Definitions

  • the blood is brought to flow from a vein, passing a double needle placed in a blood sample device, into an evacuated blood sample tube, this blood sample tube supplying the vacuum being required to promote the flow of the blood from the vein, through the double needle and into the blood sample tube.
  • the double needle and the blood sample device are generally screwed together before use, and following use these two parts are again disconnected and discarded separately.
  • the present invention relates to an improved safety blood sample device of the category mentioned in the preamble of claim 1.
  • a blood sample device of this kind is known from U.S. Pat.No. 4.643.199.
  • the tubular holder is axially displaced between the two end positions by using one hand to hold the safety shield and the other hand to pull or push the holder, the rear portion of which in both positions projects from the safety shield.
  • the locking of the holder in the positions is carried out by rotating the holder relative to the safety shield, whereby some internal locking lugs on the safety shield engage corresponding transversal slots in the holder, so that further axial displacement of holder relative to safety shield is prevented.
  • This construction is disadvantageous for various reasons. Above all both hands are needed for the displacement of the needle holder between the two end positions and for locking it in the two positions.
  • the blood sample device according to the known art is provided with a very long holder, projecting from the safety shield even in the position for use, owing to the fact that the displacement and the locking of the holder relative to the safety shield is obtained by means of this projecting rear end of the holder. This end must project so far to the rear, that the laboratory assistant is able to push or pull at the holder or to rotate it gripping this projecting end.
  • the blood sample tubes being mounted in this holder, during the mounting must be pressed home to ensure the penetration of the needle through the stopper in the upper end of the blood sample tube r these tubes must be a little longer than the holder, and that is the reason why the most frequently utilized short blood sample tubes cannot be used in connection with this known blood sample device.
  • the forward portion of the needle in the known blood taking device is not totally encapsulated by the shield in the protective position, being only protected by a removable needle shield. Following removal of this, there is a great risk of being stuck , leaving for instance an increased risk of being infected because of the no longer intact skin surface.
  • the locking • arrangement of a blood sample device of the known art is disadvantageous in being activated and deactivated by rotating the holder relative to the safety shield; the needle mounted in the bottom of the holder rotates too, and the tapering point of the needle may damage the inner side of the vein, making it more difficult to the laboratory assistant to find an intact vein next time.
  • the above mentioned disadvantages are eliminated when constructing the blood sample device according to claim 1 and claim 2.
  • Providing the holder with a finger grip element, in the following also designated a grip, for its displacement in the safety shield brings along a number of advantages: it enables the laboratory assistant to use only one hand when working with the device; the holder might be of a substantially shorter length ensuring a wide field of application as to the length of the blood sample tubes; the weight of the device is decreased; the raw material costs and the production price are decreased and the waste problems are reduced.
  • the locking arrangement is also operated by means of the grip without the need of rotating the holder relative to the safety shield, the last of the above mentioned disadvantages is eliminated, enabling the taking of blood samples in a much safer way with only a minimal risk of damaging the veins of the patient; besides the risk of forgetting to lock the holder is eliminated, as the locking takes place . automatically.
  • a further advantage of the blood sample device according to the invention should be mentioned, namely that the tapered point of the needle, in case the needle is mounted in the device during the manufacture hereof, is correctly oriented relative to the grip, so that when introducing the needle in the vein, the laboratory assistant need not search for the correct position of the needle point as it is correctly positioned from the start.
  • the blood sample taking device may be used in connection with smaller diameter tubes, often being applied when taking blood samples from children,
  • a separate double or single needle may be mounted for special applications utilizing very thin or very thick needles or enabling the using up of a surplus stock of separate needles, and
  • Fig. 1 is a sectional view of a blood sample taking device . according to the invention showing the needle in encapsula ⁇ ted position,
  • fig. 2 the same as fig. 1, but showing the needle in an intermediate position during the forward displacement of the holder
  • fig. 3 the same as fig. 1, but showing the needle in its foremost projecting position, a blood sample tube being in ⁇ serted,
  • fig. 4 is a view from above of the blood sample device, the needle being in an intermediate position
  • fig. 5 is a fragmentary sectional view of a grip according to one embodiment of the invention.
  • fig. 6 is a view from above of a blood sample device according to the invention, showing an embodiment of the slot-formed openings in the safety shield
  • fig. 7 is a fragmentary view of a blood sample device according to the invention, showing an embodiment of the further holder for small diameter tubes and a way of connecting it to the holder, and
  • fig. 8 is a fragmentary sectional view of a device of the invention with a screwed-in separate standard double needle.
  • the blood sample taking device comprises a holder 1 inten ⁇ ded to receive an evacuated blood sample tube 2.
  • the bottom of the holder 1 is adapted to carry a double needle 3-
  • the holder 1 is axially displaceable in a safety shield 4 between a blood sample taking position, where the forward portion of the needle 3 is projecting from the safety shield 4, and a protective position, where the same portion of the needle 3 is totally encapsulated inside the safety shield 4.
  • the holder 1 carrying the needle 3 can be locked in these two positions by means of locking arrangements, preferably spring-like locking arrangements.
  • the holder 1 is provided with a finger grip element 10 on one side thereof, being movable in a longitudinal slot 11 in the safety shield 4, thereby displacing the holder 1 relative to the safety shield 4.
  • the locking of the holder 1 in the end positions is accomplished by providing the grip 10 with an enlarged locking projection 12 and by providing the slot 11 with corresponding enlargements 13, as shown in fig. 4, without rotating the holder 1 relative to the safety shield 4.
  • the double needle 3 can be pre-mounted in the bottom of the holder 1, or a standard needle 3 may be mounted before the blood sample taking.
  • the rear portion of the needle 3,for penetration into the blood sample tube may be provided with a bag-shaped membrane 6, known to those skilled in the art, this bag-shaped membrane 6 being secured to a cone ring 5. Before this rear portion of the needle penetrates the penetrable, reclosable stopper 7 of the blood sample tube 2, this portion of the needle 3 is tightly encapsulated in the bag-shaped membrane 6.
  • the bag-shaped membrane 6 again tightly encapsulating the needle point, ensures that drops of blood, if any, do not leak out of the device.
  • the locking projection 12 at the grip 10 cannot be pushed out of the enlargements 13 in the slot 11, when a blood sample tube 2 is inserted in the device, which prevents any unintended release of the holder 1 during the application.
  • This locking arrangement may comprise recesses 8 in the holder 1 and corresponding locking hooks 9 on the shield 4.
  • the safety shield 4 may be provided with openings 14, for instance longitudinal slot-formed openings as shown in fig. 6, by means of which the laboratory assistant is able to hold the tube 2 by his hand, this being recommendable when utilizing the bag-shaped membrane 6 owing to the fact that the tube 2 is pressed to the rear by the membrane.
  • the holder 1 may also be provided with an arrangement to receive and hold a further holder 16 for short blood sample tubes 2 with a smaller diameter, these tubes being often used when taking blood samples from children.
  • This arrange ⁇ ment may for instance consist of a snap lock part 15 placed in the bottom of the holder 1, and corresponding projec ⁇ tions on the rim of the holder 16 for engagement with the said part 15 .
  • the perforation in the bottom of the holder 1 may be internally threaded, for attaching a separate needle, pre ⁇ ferably a separate standard double needle 18 corresponding ⁇ ly externally threaded or a separate standard single
  • (R) needle utilizing for instance a screwed-in standard LUER adaptor, or a periferal vein catheter.
  • a compression spring may be positioned between the inner forward portion 22 of the shield 4 and the outer forward portion 23 of the holder so as to obtain a quick return displacement, if desired, of the holder 1 from the blood sample taking position to the protective position and making an unintended release before use of the holder 1 im ⁇ possible.
  • the position of the holder 1 relative to the shield 4 is as shown in fig. 1, the locking arrangements 8, 9 not being activated, the needle 3 anyway totally encapsulated in the shield 4 with the holder 1 in locked position, the projection 12 being situated in the rear enlargements 13 of the slot 11.
  • the operation of the blood sample device is as follows: The grip 10 is pressed down, thereby releasing the locking pro ⁇ jection 1-2 from the rear enlargement 13 of the slot 11.
  • the holder 1 is pushed forward as shown in fig. 2 to the forward end of the slot 11 and the grip 10 is released.
  • the locking projection 12 is now, owing to the elasticity of the grip 10, situated in the anterior enlargement 13 of the slot 11.
  • the grip elasticity stabilizes the holder 1 during its displacement in the shield 4 and during the blood taking procedure.
  • An evacuated blood sample tube 2 is then partly inserted in the holder 1, just reaching the rear point of the needle 3.
  • the bag-shaped membrane 6 is penetrated and pressed together.
  • the device is now ready for use as shown in fig. 3.
  • the forward point of the needle 3, being tapered in a sloped downward fashion relative to the grip 10, is intro ⁇ quizd into a vein of the patient.
  • the evacuated blood sample tube is then pushed further forward, until the needle point has penetrated the stopper 7 of the tube 2, establishing a connection between the evacuated space in the tube and the vein of the patient. A pressure difference arises, making the blood flow freely from the vein, through the needle into the tube 2.
  • the vacuum in the blod sample tube 2 disappears, and the blood sample drawing cannot take place.
  • the pressure difference is equalized, the blood will stop flowing, and the tube 2 may be removed from the device.
  • the bag-shaped membrane automatically returns to its unfolded position, encapsulating the rear point of the needle 3. If desired a new blood sample tube may be inserted.
  • the stopper 7 of the blood sample tube 2 prevents the grip 10 from unintendedly being pressed down.
  • the grip 10 is pressed down, releasing the locking projection 12 from the anterior enlargement 13 in the slot 11.
  • the safety shield 4 is pushed forward, touching the arm of the patient, following the drawing out of the needle 3 from the vein by pushing back the grip 10 and continuing the movement to the end of the slot 11 in which position the locking hooks 9 of the shield 4 engage the recesses 8 in the holder 1. Releasing the grip 10 then brings along the insertion of the locking projection 12 in the rear enlargement 13 of the slot 11. The holder 1 is now finally secured in the shield 4, the device is in its protective position, the needle 3 being totally encapsulated in the shield 4, the disposal of the device is free of risk.
