Definitions
- the present invention relates to an equipment for blood sample collection of the type described in the introductory clause of claim 1, i.e. an equipment com ⁇ prising a hypodermic needle and a needle holder, which also includes a receiver cylinder for an evacuated vial.
- This vial has a perforatable end cap which at the inser ⁇ tion of the vial into the holder is perforated by an interior needle therein, such that hereby a suction connection is established between the specimen vial and the outer sampling needle.
- the collection of blood will be supported by the vacuum in the specimen vial, such that advantageously essentially thinner sampling needles than in the conventional, so-called open systems may be used.
- a needle is used having a holding piece which can be connected to a stub on the holder and which has a two-sided protruding needle which is pointed at both ends and constitutes both the sampling needle and the associated inner needle in the holder for cooperation with the specimen vial.
- twin needles concerned are dangerous to handle. They are also problematic in those cases where it is relevant to fill more vials from one and the same insertion of the sampling needle, as in the intermediary periods blood may freely seep from the needle.
- valve portions may be used instead of the said resilient covering tube over the inner needle.
- One of the specifi ⁇ cations (4,312,362) discloses that a valve slide is brought to uncovering a hole at the side of the inner end of the interior needle in response to the vacuum which is applied by the connection of the vial, but this construction will hereby be limited to a one-off use for filling of a single vial only, as no means are present for resetting the valve slide.
- the purpose of the invention is to provide a blood specimen collection system of the said kind by which the necessary valve function can be ensured in a suitable, effective and constructively simple manner.
- the blood specimen device being embodied as indicated in the characterizing clause of claim 1.
- the valve element is hereby constituted by the inner needle itself, which at the insertion of the vial is pushed to an open position in that the closed front of the needle is brought into engagement with the bottom end of the cylinder, such that the needle thereupon at its pointed tailend is able to perforate the seal of the vial by further insertion of the latter.
- the needle At retraction of the vial the needle will be brought along to the closed position without any dis ⁇ placement problems, whereby the equipment can be reused for insertion of a new vial.
- the inner needle and the outer sampling needle or its holding base are placed radially offset from one another, as the inner needle can thereby be opened by being pressed against a stop, which lies offset from the connecting passage to or from the sampling needle; hereby it can be totally avoided that the inner needle must be connected to spe ⁇ cial, problem incurring guiding and stop portions, cf. USA Patent specification No. 4,166,450. It is hereby an extremely lucky or significant circumstance that also for other reasons it is advanta ⁇ geous that the inner and the outer needle are radially offset from one another, viz. by a central positioning of the inner needle and an eccentric or peripheral plac ⁇ ing of the outer needle.
- the holder may be made of a transparent material such that the insertion of the vial may wait until it is ascertained that a trace of effusing blood from the sampling needle appears at the bottom portion of the holder.
- Fig. 1 is an exploded perspective view of a set of collection appliances constituting part of a collection system according to the invention.
- Fig. 2 is a lateral sectional view of two of the appliance components.
- Fig. 3 is a more detailed sectional view of an end portion of the applied holder.
- Figs. 4 and 5 are sectional views of an embodiment of a vial for use in the system, and
- Fig. 6 is a sectional view of another embodiment of the vial.
- a collection set comprising a sampling needle 2, a holder 4 and a vial 6.
- the needle 2 is made in the usual manner for injection needles, viz. comprising a holder portion 8 having a one-sided pro ⁇ jecting needle 10 and a bushing 12 at the other side of a collar 14.
- the bushing 12 is intended for insertion into or screwing onto a connector stub 16 on the holder 14, this being easily performed when a cover 18 is placed over the needle, such cover encasing the needle 10 and being removed after the fitting, when the appli ⁇ ance is required.
- the holder 4 is tubular having a closed end at the stub 16 and an opposing open end where the tube com ⁇ prises a protruding collar 20. Inside the holder 4 and in connection with the stub 16 a central needle 22 is placed projecting slightly inwardly into the holder, however nowhere near to the area at the open end, such that in practice this needle is inaccessible to contact.
- the vial 6 is an evacuated glass, the mouth of which is covered by a cap 24 that can be perforated by the needle 22 when the vial is inserted into the holder 4.
- the perforation requires a certain pressure, but the vial can be pressed in with quite a heavy force, using the collar 20 as a grip just like when pressing home a syringe piston.
- the appliances can be applied thus that the needle 10 upon assembly with the holder 4 is inserted into a vein whereupon the vial 6 is inserted and is pressed into the holder 4.
- the vacuum in the vial 6 spreads to the foremost needle 10 and the blood is drawn to the vial 6.
- this is filled as required it can simply be removed from the holder, which is easily done because the vial in the inserted position protrudes substantially rearwardly from the holder. If no more samples are to be collected, the needle 10 may be withdrawn and provided with the cover 18, after which the unit 2, 4 may be taken to waste collection.
- the needle 10 may remain in the vein, and upon removal of the vial 6 a new vial 6 may be inserted into the holder.
- a valve-blocking of the needle 22 In principle this can be brought about in the same way as with the hitherto used rearward protruding needle portions on the needles 2, viz. by covering of the needle 22 with a resilient, narrow case which at the pressing against the cap 24 will become perforated and be pushed forward to exposing the needle, but according to the invention it is preferred to make use of a valve device, which is effective at the fixed end of the needle.
- the needle 22 is mounted in a passage in a holder plug 26, which is pressed in to a position right against the closed end of the holder 4, and outermost this passage communicates with a recess 28 in the plug 26, the needle from the beginning being mounted such that with its rearmost collar portion 30 it abuts on the recess bottom at the relevant end of the said passage for the needle.
- the recess 30 is in open connection with a central passage 32 through the stub 16 on the holder 4, this stub being placed eccentric on the end portion of the holder, while the needle 22 is situ ⁇ ated centrally in the holder.
- the end of the needle at the collar 30 is closed tightly, preferably by being pressed together and folded out as shown by 31.
- the eccentric position of the stub 16 is tantamount to the outer needle 10 being situated close to the ex ⁇ tension of an outer wall area of the holder 4, which is an advantage at the insertion of the needle into the vein, as the holder then permits a very acute-angled insertion of the needle into the vein.
- the portion of the inner needle 22 which is accom ⁇ modated in the passage in the plug 22 is provided with side openings 34 which are kept closed by the passage in the position shown by solid lines in Fig. 3.
- the needle will be pushed back when the cap 24 is pressed against its point, and hereby the needle will be displaced to the position shown in dashed lines in which the collar 30 pushes against the front of the holder 4, and in which the side openings 34 communicate with the recess 28 and thereby with the passage 32 through the stub 16, i.e. the needle 22 will thereby communicate with the outer needle 10.
- the point of the needle 22 will penetrate the cap 24 as the needle 22 is now prevented from further displacement, and the vacuum in the vial will thus spread to the collection needle 10.
- the needle 22 When the vial 6 is extracted, the needle 22 will be carried along the first stretch as care is taken that its frictional connection with the cap 24 is stronger than its friction with the passage through the plug 26, and the first result of the extraction will thus be that the needle 22 is brought back to the position in which the side openings 34 are situated inside the said pas ⁇ sage, i.e. closed outwardly, and as also the free tail end of the needle is closed at 31, the interior of the needle is thus completely blocked from the connection with the recess 28 and the needle 10.
- the in ⁇ vention it is preferred to work with a newly innovated type of vial, where the perforatable element is a disc of rubber or a corresponding material which is clamped by means of a screw cap mounted on a threaded element closely connected with the vial glass, as such an embo ⁇ diment with increased safety can be adapted to the pur ⁇ pose and besides shows further advantages.
- FIG. 4-5 An example of such a vial is shown in Figs. 4-5 where a plug 40 is inserted in the vial mouth so as to seal against the vial by means of a sealing ring 42, the plug having a protruding portion 43 which is provided with an outer threading.
- the plug has a completely open central passage 44, and on top of the plug a rubber disc 45 is laid, which is tightened against the plug by means of a screw cap 46 in the overside of which is provided a central hole 48.
- the unit 40, 45, 46 can be assembled in advance for closing the vial at the evacuation thereof, and at the use the needle 22 needs only penetrate the disc 45. It is not crucial whether this perforation takes place exactly centrally, but structurally it is convenient letting the needle 22 be centrally placed.
- the sealing ring 42 is provided as a flat disc having a hole 49, the diameter of which is noticeably smaller than the outer diameter of the plug area 50, on which the ring be mounted by insertion from the free end of the plug portion 40.
- the disc 42 will be deformed as shown in Fig. 5, viz. to forming of an upwardly conical expanding tube portion, which by insertion into the vial can tighten firmly against the inside of the latter even though tolerance deviations occur with respect to the inner diameter of the vial and the outer diameter of the sealing disc 42.
- the assembled plug body can be inserted into the vial while this is kept under vacuum.
- the blood sample can be taken out after unscrewing the cap 46 either by pouring out or by drawing by a pi ⁇ pette.
- the plug unit shown has the great advantage that it is thus easily opened without removing the plug, and that the plug, however, is removable from a smooth cylindrical vial which thereby after centrifuging can cooperate with a serum separator. It has previously been attempted to provide the vial glass itself with an outer thread for a screw cap, but this is hardly possible without deformation of the smooth cylindrical inside, and thereby the vial is made unsuitable for cooperation with a usual serum separator.
- Fig. 6 is shown another embodiment of the vial, where the holding plug or the non-illustrated screw cap comprises a bushing portion 52, which can be placed on the outside of the vial mouthing and tighten against the latter by means of an embedded sealing ring 54.
- This embodiment which likewise cooperates with a smooth- walled vial, is advantageous by being easily 'deflated-' when this is required, as one may press against the lower edge of the portion 52 and thereby produce a cap ⁇ sizing.
