Definitions
- the present invention relates to a device for drawing fluid from a lumen.
- the present invention relates to a device for drawing blood from a blood vessel.
- Intravenous blood collection devices have long been used to draw bodily fluids from patients.
- collecting a bodily fluid such as blood, involves inserting a needle into a vessel or lumen from which the fluid is to be drawn and then collecting the fluid as it flows through the needle.
- some intravenous blood collection devices have been provided with transparent windows that allow a user to observe a "flash" of blood that confirms that the needle tip is correctly positioned.
- the flash may be small or obscured, meaning that it may be difficult to detect.
- the invention resides broadly in a device for drawing fluid from a lumen comprising a body, a first needle portion extending from a forward portion of the body and a second needle portion extending from a rear portion of the body, wherein the body includes an observation portion adapted to allow visual observation of the fluid, and wherein the observation portion is provided with enhancement means adapted to enhance the visibility of the fluid in the observation portion.
- the invention resides in a device for drawing fluid from a lumen comprising a body, a first needle portion extending from a forward portion of the body and a second needle portion extending from a rear portion of the body, wherein the body includes an observation portion adapted to allow visual observation of the fluid, and wherein the observation portion is configured to enhance the visibility of the fluid in the observation portion.
- the first and second needle portions may be of any suitable size, shape or configuration. Preferably, however, the first and second needle portions are substantially tubular so that a fluid (for instance, blood) may flow through the first and second needle portions.
- a fluid for instance, blood
- the first needle portion may be adapted to be inserted into a patient's body.
- the first needle portion may be adapted to pierce or puncture the patient's skin and enter a lumen (such as a blood vessel) from which fluid may be drawn.
- the first needle portion is adapted to function as a puncture needle.
- the second needle portion is adapted to be brought into communication with a medical device.
- the second needle portion may be adapted to be brought into contact with a fluid collection vessel (such as a vial, test tube, flask, bag or the like), a flexible tube, a syringe or the like.
- the medical device may be provided with a seal, meaning that the second needle portion may be required to pierce of puncture the seal (such as a plug, bung, membrane or the like) in order to be brought into communication with the medical device.
- the second needle portion is adapted to function as a puncture needle.
- the second needle portion may be provided with covering means adapted to prevent leakage of fluid from the second needle portion before the second needle portion is brought into contact with a medical device.
- Any suitable covering means may be used, although in a preferred embodiment of the invention, the covering means may comprise a flexible sheath adapted to prevent any fluid exiting the second needle portion from leaking out of the device. It is envisaged that, when the second needle portion is brought into communication with a medical device, the second needle portion will puncture the covering means, thereby allowing fluid to flow from the second needle portion into the medical device.
- the first needle portion may form a part of a first needle, while the second needle portion may form a part of a second needle, the first and second needles being spaced apart from one another within the body of the device.
- the first and second needle portions form part of a single needle. In this embodiment, it is envisaged that the first and second needle portions form opposing ends of a single needle.
- the needle extends entirely through the body such that the first needle portion extends from a forward portion of the body while the second needle portion extends from a rear portion of the body.
- the body may comprise a passageway or bore therein through which the needle may be passed.
- the passageway may be of any suitable dimensions, however in a preferred embodiment of the invention, the passageway has a diameter along at least a portion of its length that is large enough to retain the needle in the passageway in a frictional engagement. Typically, this frictional engagement may occur at or toward the forward of rearward end of the body.
- the passageway may include a chamber portion along a portion of its length.
- the chamber portion is of a greater diameter than the remainder of the passageway such that a gap is formed between the needle and the inner wall of the chamber portion.
- the needle is provided with one or more apertures that, when the device is assembled, align with the chamber portion. In use, it is envisaged that a portion of the fluid flowing through the needle will enter the chamber portion through the one or more apertures in the needle.
- the chamber portion may be of any suitable size or configuration.
- the chamber portion may extend entirely about the circumference of the needle, thereby comprising an annular chamber surrounding the needle.
- the chamber portion may extend only partially around the circumference of the needle.
- the volume of the chamber portion is relatively small.
- the volume of the chamber is smaller than the volume of the needle over which the chamber lies such that only a small amount of fluid is required to be diverted out of the needle and into the chamber before the chamber is filled.
- the chamber may be or form a part of the enhancement means that enables a user to observe the fluid in the chamber portion, rather than a large volume of fluid being required to enable the user to view the fluid.
- the chamber is annular, another advantage of the invention will be that the fact that the fluid is present will be ascertainable from any direction when viewing the device. A smaller volume of fluid can be used in the annular chamber than would be used to fill a cylindrical chamber and the annual chamber will typically have a larger surface area than a cylindrical chamber of the same volume.
- the observation portion of the body is fabricated from a transparent or semi-transparent material (such as glass or plastic).
- the observation portion is substantially aligned with the chamber portion of the passageway such that fluid entering the chamber portion may be observed through the observation portion of the body.
- the observation portion may comprise a portion of the outer surface of the body.
- the entire body may be fabricated from a transparent or semi-transparent material so that the flow of fluid may be observed from any angle. This is particularly the case if the chamber portion extends entirely about the circumference of the needle.
- the observation portion is provided with enhancement means to enhance the visibility of the fluid in the observation portion.
- enhancement means to enhance the visibility of the fluid in the observation portion.
- the enhancement means may be of any suitable form. However, in a preferred embodiment of the invention the enhancement means comprise one or more recesses or shaped portions in the body.
- the recesses may be of any suitable size, shape or configuration.
- the one or more recesses may be in the form of one or more dimples in the surface of the body.
- the one or more recesses may be in the form of channels or grooves extending in one or more directions along the surface of the body.
- the one or more recesses are shaped so as to refract, multiply and/or enhance the image of the fluid in the chamber portion to make the fluid easier for a user to see.
- the one or more recesses are substantially concave in order to improve the refraction, multiplication and/or enhancement of the image of the fluid in the chamber portion.
- the enhancement means may be a particular colour as some colours or tints will make some fluids more visible to the naked eye of an operator. It is also possible that the enhancement means may contain a material to react with the fluid to make the fluid more easily visible to the naked eye of an operator.
- the enhancement means may therefore be a physical enhancement means or a chemical enhancement means. If the frictional engagement between the needle and the passageway is not sufficient to retain the needle within the body, retaining means may be used to retain the needle in place. Preferably, the retaining means are adapted to seal one or more ends of the body (in order to prevent leakage of fluid) and/or to retain the needle in place.
- one or both of the front and rear portions of the body may be provided with retaining means such as retaining caps or retaining plugs.
- the retaining means may be in the form of a settable or hardenable material, such as an adhesive or a thermosetting plastic, applied to one or more ends of the body.
- the needle is retained in place by the set or hardened material.
- one or both of the retaining caps or retaining plugs and the body may be provided with engagement means adapted to improve the engagement between the retaining caps or retaining plugs and the body.
- the retaining caps or retaining plugs may be retained within the body using adhesives or the like.
- connection means adapted to allow the device to be connected to a suitable medical device.
- the connection means may be of any suitable form.
- the connection means may be one or more projections, clips, fasteners or the like.
- the connection means may comprise a screw-threaded portion adapted for connection to a complementary screw-threaded portion in a medical device.
- the connection means will typically be provided on a rear portion of the body adjacent the second needle portion.
- one or both of the first and second needle portions may be provided with needle caps during transportation and storage.
- the invention resides broadly in a device for drawing blood from a lumen, comprising a body, a first needle portion extending from a forward portion of the body and a second needle portion extending from a rear portion of the body, wherein the body includes a transparent observation portion adapted to allow visual observation of the blood, and wherein the observation portion is provided with one or more recesses adapted to enhance the visibility of the blood in the observation portion.
