Definitions
- the present invention relates to connectors for a fluid path, and more particularly an adapter for coupling a medication providing device with a connector for providing medication to a patient.
- a connector may be made up of two portions, with the portions being connected by complementary configured opposing surfaces. Such two portions connector ensures that the one line from one portion of the connector would not be wrongly connected to a different medication line.
- a fastening mechanism comprised of such complementary connecting portions is disclosed in U.S. Pat. No. 6,612,624 and its parent U.S. Pat. No. 6,402,207.
- the '624 patent discloses in particular a ratchet mechanism, as part of the connector, that prevents or impedes the uncoupling of one portion of the connector from a syringe to which the other portion may be connected.
- the ratchet mechanism is dependent on the interaction of the teeth on the inner surface of an outer sleeve with a pawl of an inner body that fits into the outer sleeve, if the syringe were to be tightened too forcefully, the inner body would pop out of the outer sleeve.
- the ratchet mechanism is a portion of the connector that does not fully isolate the relative rotation of the outer sleeve and the inner body.
- the instant invention adapter is adapted to be interposed between a medication providing device and a connector.
- the adapter is designed to prevent the medication providing device from being removed therefrom, once the device is secured to one end of the adapter.
- the other end of the adapter is configured to accept a connector.
- the connector is rotatably connected to the adapter in one direction. Once fully connected, any further rotational movement along the same direction would simply cause the connector to rotate freely relative to the adapter. With a rotational motion in a counter direction, the connector can be removed from the adapter.
- the adapter of the instant invention includes an outer cylindrical sleeve or a housing shroud that has an internal circumferential hub catch.
- a plurality of bumps extend from the inner wall of the housing shroud toward the central axis of the shroud.
- Fitted to this housing shroud is a cylindrical inner shroud that has a protrusion circumferentially formed proximate to its distal end that snap-mates to a circumferential groove formed at the distal end of the shroud.
- the inner shroud and the housing shroud are rotatable relative to each other.
- a plurality of teeth extend from the proximal end of the inner shroud. When biased by a given force, these teeth of the inner shroud would act against the bumps extending from the inner wall of the housing shroud to prevent the inner shroud from rotating relative to the housing shroud.
- the extending teeth have inclining ramps that prevent the teeth from acting against the bumps, thereby allowing the two shrouds to rotate freely relative to each other when the biasing force is removed.
- the inner shroud may be internally threaded for accepting a specially designed connecting end of the connector.
- a third component of the adapter of the instant invention is a core that fits to the housing shroud from the latter's other end.
- the core has a cylindrical central portion defined by a chamfered flange and a ring-shaped flange. This cylindrical central portion mates with the hub catch of the housing shroud that has a number of fingers configured to allow the chamfered flange to pass through but prevent the chamfered flange, the back of which is flat, from passing in the reverse direction.
- the core is non-removably fitted to, but rotatable freely relative with, the housing shroud.
- the respective dimensions of the cylindrical central portion of the core and the opening formed by the hub catch fingers are configured to allow the core to rotate freely relative to the housing shroud. With the core fitted to the housing shroud, a medication providing device can be mated to the proximal end of the core.
- the connector for example a luer connector, of the medication providing device allows the medication providing device such as a syringe to be mated to the proximal connector of the core.
- the medication providing device such as a syringe
- the core will rotate freely along the direction of the counter torque.
- the medication providing device is therefore prevented from being removed from the adapter. Additional torque in the direction that mates the medication providing device to the core does not cause any additional tightening, as the core will also rotate freely relative to the shroud. Thus, once the medication providing device is mated to the core, it could not be removed therefrom.
- the instant invention therefore relates to an adapter for use with a medication providing device and a connector for providing medication to a patient.
- the adapter includes a housing shroud and an inner shroud fitted to the housing shroud.
- the inner shroud has an opening for accepting a connecting end of the connector such that the connector, once mated to the inner shroud, is freely rotatable in one direction and is removable from the inner shroud when rotated in a counter direction.
- the adapter further includes a core fitted in the housing shroud to allow the medication to be routed from the medication providing device to the connector.
- the core has a proximal end for enabling the medication providing device to be connected to the adapter.
- the medication providing device is not removable from the adapter once it is connected thereto.
- the present invention also relates to a combination of a shroud having two open ends and an inner shroud non-removably fitted into one of the open ends of the shroud.
- the inner shroud has a connector end for enabling it to be mated to a given medication conveying connector.
- the inner shroud is rotatable freely in one direction once the given connector is mated thereto.
- the given connector is removable from the inner shroud when it is rotated in a counter direction.
- the combination further includes a core that is non-removably fitted to the other end of the shroud.
- the core has a through passage and a connector end for enabling the core to be mated to a luer connector of a medication providing device.
- the medication providing device once mated to the connector end of the core, is not removable from the core.
- the instant invention also relates to a method of routing a medication from a given medication providing device that includes the steps of providing a given medication conveying connector, providing an adapter having a shroud with one and other open ends, non-removably fitting an inner shroud into one end of the shroud and non-removably fitting a core into the other end of the shroud.
- the inner shroud has a connector end that enables the inner shroud to be mated to the given medical conveying connector, while the core has a through passage and a connector end for enabling it to be mated to the connector of the medication providing device that, once mated to the connector end of the core, is not removable from the core.

Abstract
An adapter connector includes a housing shroud that is fitted at one end with a core and at its other end with an inner shroud. A catch hub is provided within the housing shroud for non-removably maintaining the core to the housing shroud. The core is rotatable relative to the housing shroud. The inner shroud has a catch mechanism that enables it to mate readily with a connector, if the connector is rotated in one direction. The catch mechanism is further configured to allow the connector to be removed if it were to be turned in a counter rotational direction. The connecting portion of the inner shroud is configured to accept a complementary connector. The connecting portion of the core likewise is configured to accept a complementary connector of the medication providing device.
Description
- The present invention relates to connectors for a fluid path, and more particularly an adapter for coupling a medication providing device with a connector for providing medication to a patient.
- To prevent mis-connection of a fluid line to a device containing a particular medication, it has been shown in the prior art that a connector may be made up of two portions, with the portions being connected by complementary configured opposing surfaces. Such two portions connector ensures that the one line from one portion of the connector would not be wrongly connected to a different medication line. A fastening mechanism comprised of such complementary connecting portions is disclosed in U.S. Pat. No. 6,612,624 and its parent U.S. Pat. No. 6,402,207. The '624 patent discloses in particular a ratchet mechanism, as part of the connector, that prevents or impedes the uncoupling of one portion of the connector from a syringe to which the other portion may be connected. In practice, since the ratchet mechanism is dependent on the interaction of the teeth on the inner surface of an outer sleeve with a pawl of an inner body that fits into the outer sleeve, if the syringe were to be tightened too forcefully, the inner body would pop out of the outer sleeve. Moreover, as disclosed in the '624 patent, the ratchet mechanism is a portion of the connector that does not fully isolate the relative rotation of the outer sleeve and the inner body.
- The instant invention adapter is adapted to be interposed between a medication providing device and a connector. The adapter is designed to prevent the medication providing device from being removed therefrom, once the device is secured to one end of the adapter. The other end of the adapter is configured to accept a connector. The connector is rotatably connected to the adapter in one direction. Once fully connected, any further rotational movement along the same direction would simply cause the connector to rotate freely relative to the adapter. With a rotational motion in a counter direction, the connector can be removed from the adapter.
- The adapter of the instant invention includes an outer cylindrical sleeve or a housing shroud that has an internal circumferential hub catch. In addition, a plurality of bumps extend from the inner wall of the housing shroud toward the central axis of the shroud. Fitted to this housing shroud is a cylindrical inner shroud that has a protrusion circumferentially formed proximate to its distal end that snap-mates to a circumferential groove formed at the distal end of the shroud. The inner shroud and the housing shroud are rotatable relative to each other.
- A plurality of teeth extend from the proximal end of the inner shroud. When biased by a given force, these teeth of the inner shroud would act against the bumps extending from the inner wall of the housing shroud to prevent the inner shroud from rotating relative to the housing shroud. The extending teeth have inclining ramps that prevent the teeth from acting against the bumps, thereby allowing the two shrouds to rotate freely relative to each other when the biasing force is removed. The inner shroud may be internally threaded for accepting a specially designed connecting end of the connector.
- A third component of the adapter of the instant invention is a core that fits to the housing shroud from the latter's other end. The core has a cylindrical central portion defined by a chamfered flange and a ring-shaped flange. This cylindrical central portion mates with the hub catch of the housing shroud that has a number of fingers configured to allow the chamfered flange to pass through but prevent the chamfered flange, the back of which is flat, from passing in the reverse direction. Thus, once the central portion of the core mates with the hub catch, the core is non-removably fitted to, but rotatable freely relative with, the housing shroud. The respective dimensions of the cylindrical central portion of the core and the opening formed by the hub catch fingers are configured to allow the core to rotate freely relative to the housing shroud. With the core fitted to the housing shroud, a medication providing device can be mated to the proximal end of the core.
- The connector, for example a luer connector, of the medication providing device allows the medication providing device such as a syringe to be mated to the proximal connector of the core. Once the medication providing device is mated to the core, if a user were to try to remove the medication providing device from the core by applying a counter torque to the medication providing device, the core will rotate freely along the direction of the counter torque. The medication providing device is therefore prevented from being removed from the adapter. Additional torque in the direction that mates the medication providing device to the core does not cause any additional tightening, as the core will also rotate freely relative to the shroud. Thus, once the medication providing device is mated to the core, it could not be removed therefrom.
- The instant invention therefore relates to an adapter for use with a medication providing device and a connector for providing medication to a patient. The adapter includes a housing shroud and an inner shroud fitted to the housing shroud. The inner shroud has an opening for accepting a connecting end of the connector such that the connector, once mated to the inner shroud, is freely rotatable in one direction and is removable from the inner shroud when rotated in a counter direction. The adapter further includes a core fitted in the housing shroud to allow the medication to be routed from the medication providing device to the connector. The core has a proximal end for enabling the medication providing device to be connected to the adapter. The medication providing device is not removable from the adapter once it is connected thereto.
- The present invention also relates to a combination of a shroud having two open ends and an inner shroud non-removably fitted into one of the open ends of the shroud. The inner shroud has a connector end for enabling it to be mated to a given medication conveying connector. The inner shroud is rotatable freely in one direction once the given connector is mated thereto. The given connector is removable from the inner shroud when it is rotated in a counter direction. The combination further includes a core that is non-removably fitted to the other end of the shroud. The core has a through passage and a connector end for enabling the core to be mated to a luer connector of a medication providing device. The medication providing device, once mated to the connector end of the core, is not removable from the core.
- The instant invention also relates to a method of routing a medication from a given medication providing device that includes the steps of providing a given medication conveying connector, providing an adapter having a shroud with one and other open ends, non-removably fitting an inner shroud into one end of the shroud and non-removably fitting a core into the other end of the shroud. The inner shroud has a connector end that enables the inner shroud to be mated to the given medical conveying connector, while the core has a through passage and a connector end for enabling it to be mated to the connector of the medication providing device that, once mated to the connector end of the core, is not removable from the core.

FIG. 3 showsadapter 2 in its assembled form withinner shroud 36 andcore 38 respectively fittingly mated tohousing shroud 30. - A perspective view of
housing shroud 30 is shown inFIG. 4A . Together with the sectional views ofFIGS. 4B and 4C and the end view ofFIG. 4D ,housing shroud 30 is shown to have a first ordistal opening 32 and a second orproximal opening 34. As best shown in the sectional views ofFIGS. 4B and 4C , ahub catch 40 made up of extendingfingers 42 is provided at the proximal portion ofhousing shroud 30. Each offingers 42 has afinger tip 44 that extends toward thelongitudinal axis 46 ofcylindrical housing shroud 30 to form anopening 48 that has a smaller diameter thanproximal opening 34.Finger tips 44 of thefingers 42 that make uphub catch 48 are chamfered in the direction of opening 34 and yet are flat when viewed from the direction ofopening 32. Atdistal opening 32 ofhousing shroud 30 there is alip 50.Opening 32 is reduced in diameter atlocation 52. As can be seen from the end view ofFIG. 4D , which is viewed from opening 32, each offingers 42, best represented byfingertips 44, is separated from its adjacent fingers by anotch 54 that provides additional flexibility to the fingers whencore 38 is inserted tohousing shroud 30 viaopening 34. Also shown inFIG. 4D , as well as the cross-sectional views ofFIGS. 4B and 4C , are a plurality ofbumps 56 that extend inwardly towardlongitudinal axis 46. -
FIGS. 5A-5D showinner shroud 36 of the instant invention adapter. As shown,inner shroud 36 has a throughbore 53 that extends from itsdistal end 54 to itsproximal end 56. At its distal end there is aprotrusion 58 formed circumferentially at its outer surface.Outer wall 60 extends fromdistal end 54 toproximal end 56, ending with a plurality ofteeth 62 that extend longitudinally away fromproximal end 56. Each of the teeth has an apex 62 a, aramp portion 62 r and anupright portion 62 u. Each of the teeth is separated from its adjacent teeth by aspace 64.Inner shroud 36 is internally threaded from itsproximal opening 54 through a major portion of the shroud, per indicated bydesignation 66. -
Core 38 of the adapter of the instant invention is best shown inFIGS. 6A-6D .Core 38 comprises at its proximal portion a connector end, in the form of a luer fitting 68 that allows it to be coupled to a luer end of a medication providing device such as for example a syringe or medication pump. Extending from the proximal portion ofcore 38 is acircumferential flange 70 that has a diameter substantially the size ofproximal opening 34 ofhousing shroud 30. A cylindricalcentral portion 72 extends fromflange 70 to ashoulder flange 74 that has a flatrear surface 76 facingflange 70.Shoulder flange 74 is chamfered at an angle along itssurface 78 so that the widest portion ofshoulder flange 74 extends at an angle inwards towardslongitudinal axis 46 until it joins the distalmale portion 80. A bore 82 throughcore 38 extends from the tip ofdistal portion 80 to opening 84 at the proximal end ofcore 38. - In combination, the adapter of the instant invention has fitted into
housing shroud 30 at itsproximal opening 34core 38 and at itsdistal opening 32inner shroud 36. With reference toFIGS. 4A-4D , 5A-5D and 6A-6C, it can be seen thatinner shroud 36 is mated tohousing shroud 30. More particularly, thecircumferential protuberance 58 ofinner shroud 36 is press or snap fitted tospace 51 at the distal end ofhousing shroud 30. Since the cross dimension ofinner shroud 36 is configured to fit withinspace 51 ofhousing shroud 30, onceprotuberance 58 is movably mated tospace 51 and is retained bylip 50,inner shroud 26 is no longer removable fromhousing shroud 30.Protuberance 58 ofinner shroud 36 is slidably movable withinspace 51 between reduceddiameter location 52 andlip 50, per shown by bi-directional arrows 59.Inner shroud 36 therefore is movable axially relative withhousing shroud 30. -
Inner shroud 36 may be biased relative tohousing shroud 30 in the direction indicated by directional arrow 86 (FIG. 4B ) whenconnector 4 is being coupled toadapter 2 via opening 54 ofinner shroud 36. Whenconnector 4 is being threadingly mated toinner shroud 36, a force is applied by the user, i.e., a torque in the direction to lockconnector end 10 ofconnector 4 to the internal threadedportion 66 ofinner shroud 36. The torque force, which is combined with a biasing forward force, causesinner shroud 36 to be pushed along the direction ofdirectional arrow 86 so thatteeth 62 ofinner shroud 36 would come into contact withbumps 56 formed internally athousing shroud 30.Bumps 56 then act as a backstop to enable the user to threadinglymate connector 10 toinner shroud 36, and thereforeadapter 2. - Once
connector end 10 is fully mated to the threadedportion 66 ofinner shroud 36, ifconnector 4 is rotated further in the direction of the locking torque movement,inner shroud 36 would pull away and rotate freely, asramp portion 62 r ofteeth 62 would guideteeth 62 away from bumps 56. But if a counter torque were to be applied toconnector 4 to rotateinner shroud 36 in a direction opposite to that ofmating connector 4 toinner shroud 36,connector 4 is removable frominner shroud 36, asback portion 62 b of each ofteeth 62 acts against a side of acorresponding bump 56 to thereby prevent rotation ofinner shroud 36 relative tohousing shroud 30. As a result,connector 4 is removable fromadapter 2 when it is rotated in a direction counter to the rotation needed to thread it intoadapter 2. -
Core 38 is fitted tohousing shroud 30 via itsproximal opening 34. Ascore 38 is pushed intohousing shroud 30, the chamferedsurface 78 ofshoulder 74, since it is at a forward incline, is able to readily causecatch fingers 44 ofhousing shroud 30 to slightly flex, particularly since theadjacent fingers 44 are separated byslots 54, so thatshoulder 76 would pass opening 48 ofcatch hub 48. Onceshoulder 74 fully passes thecatches 44 offingers 42, since its back surface is flat,core 38 is prevented bycatch hub 48, more specifically by the plurality offingers 42, from being removed or separated fromhousing shroud 30. -
Distal opening 34, as best shown in the cross-sectional views ofFIGS. 4B and 4C , has across section 35 that has the same diameter asflange 70. Aledge 37 at opening 34 preventsflange 70 from being pushed further intohousing shroud 30, perdirectional arrow 88. Thus, oncecore 38 is fitted tohousing shroud 30, it is non-removably fitted thereto. The cylindricalcentral portion 72, which is sandwiched byshoulder 76 andflange 70, is positioned within the proximal portion ofhousing shroud 30. - The
nose portion 80 ofcore 38 is configured to have a length that allows it to be positioned withinspace 51 ofhousing shroud 30, as best shown inFIG. 3 . Thus positioned,nose portion 80 is adaptable to mate withconnector end 10 ofconnector 4, whenconnector 4 is mated toinner shroud 36. Onceconnector 4 is mated toinner shroud 36, a through path extending from opening 20 ofconnector 4 to opening 84 ofcore 38 is established to thereby enable fluid such as medication to pass from a medication providing device to the connector, and from there through the catheter connected thereto to the patient. - As
core 38 is non-removably connected tohousing shroud 30 bycentral portion 72 being rotatably mounted to catchhub 42,core 38 is rotatable freely either clockwise or counterclockwise relative tohousing shroud 30. The respective dimensions ofproximal opening 34 ofhousing shroud 30 andflange 70 may be manufactured to establish a predetermined friction betweenhousing shroud 30 andcore 38 to enable a user to readily connect a medication providing device, such as for example a conventional syringe or the connector of a medication pump, toluer connector 68 ofcore 38. But once the syringe is fully connected tocore 38, due to the fact thatcore 38 is freely rotatable relative tohousing shroud 30, the medication providing device could no longer be removed fromadapter 2, as any rotational movement applied to the medication providing device would causecore 38 to rotate freely relative tohousing shroud 30. - By thus preventing the detachment of the medication providing device from
adapter 2 once it is connected to theluer connector end 68 ofcore 38, the adapter of the instant invention ensures that the medication in the medication providing device could only be conveyed to the connector that has a connector end that could mate correctly only with the connector end of the adapter, i.e., threadedconnector portion 66 ofinner shroud 36 for the embodiment being discussed. Of course, ifconnector 4 has a differently configuredconnector end 10, a corresponding connector end is needed atinner shroud 36 for properly mating therewith.Adapter 2 of the instant invention is therefore able to provide a bridge for connecting a medication providing device to the proper connector, to thereby ensure that a correct fluid pathway is established to convey the correct medication to the patient.
