Description

  The present invention relates to a puncture needle cartridge and a blood collection puncture device, and more particularly to a blood collection puncture device configured to take out a puncture needle one by one from a plurality of puncture needles used when measuring blood glucose levels, and the like. The present invention relates to a puncture needle cartridge for a puncture device for medical use.

  Diabetes patients themselves measure blood sugar levels several times a day. At the time of this measurement, it is necessary to collect a small amount of blood from the fingertip or the like. For this purpose, as shown in FIG. 8, a disposable puncture needle 105 is attached to a device called a puncture instrument 101, and a puncture needle 105 is used to puncture a fingertip, an arm, etc., and to measure bleeding from the punctured site. Use.

  A typical puncture device 101 includes a cylindrical main body portion 130 and a cap portion 153. The cylindrical main body portion 130 includes a first spring 132 for driving the attached puncture needle 105, a second spring 134 for retracting the punched puncture needle 105, and a compressed first spring 132. Has a fire button 117 for releasing.

In use, the cap 153 is removed from the cylindrical main body portion 130, the puncture needle 105 is attached to the cylindrical main body portion 130, and the cap 153 is put on the cylindrical main body portion 130 again. Then, the first spring 132 is compressed to enable the puncturing operation, the puncture portion pressing surface 136 of the cap 153 is applied to the puncture portion such as a fingertip, and the firing button 117 is pressed, the puncture needle 105 is ejected. (In the structure of FIG. 8, it is unclear how the puncture needle 105 is driven out by the action of the first spring 132 when the firing button 117 is pressed. I hope you can correct Figure 8 and add an explanation of its operation.) After the puncture is performed, the puncture needle 105 is immediately retracted from the fingertip or the like by the second spring 134, and blood can be collected by the above-described operation. Here, it is very dangerous from the viewpoint of hygiene to reuse the puncture needle 105 once used, and therefore, the puncture needle 105 needs to be replaced at the next use (see, for example, Patent Document 1).

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
1 is an external perspective view of a blood sampling puncture device according to Embodiment 1 of the present invention, FIG. 2 is a cross-sectional view showing an internal configuration of the puncture device, and FIG. 3 is an external view of a puncture needle cartridge used in the puncture device. FIG. The puncture device for blood collection and the puncture needle cartridge are used for collecting a small amount of blood such as when measuring a blood glucose level. FIG. 4 is a diagram showing an operation of setting a puncture needle on the instrument body in order to perform a puncture operation.

  As shown in FIGS. 1 and 2, the puncture device 1 according to Embodiment 1 of the present invention has a main body bottom case 3, and a puncture needle holding rod 4 is provided in the main body bottom case 3. 2 and a puncture set lever 8 are provided. The puncture needle 5 is inserted and loaded into the puncture needle holding rod 4 to a predetermined depth. In this case, as shown in FIG. 3, a plurality of puncture needles 5 are integrally formed on the frame of the cartridge by resin integral molding on the puncture needle cartridge 18 in a line. Furthermore, each puncture needle 5 is connected to the frame of the puncture needle cartridge 18 by a thin resin film having a thickness of 0.1 mm or less, for example, at the puncture needle separation groove 5a. The part is set in a state of being buried in the main body frame side of the cartridge.

Here, an operation procedure for attaching the puncture needle 5 to the puncture device 1 will be described.
First, in a state where the puncture needle set lever 8 is not set (in the state shown in the drawing, it is lowered), the axes of the puncture needle loading port 9 of the puncture device 1 and the puncture needle 5 on the puncture needle cartridge 18 are aligned. The puncture device 1 is pushed in while matching (FIG. 4 (a)). At this time, in order to facilitate the operation, as shown in FIG. 3, one of the puncture needles 5 arranged in parallel (the one at the left end in the drawing) is brought up from the initial position by a predetermined angle. In this state, the rear end portion of the puncture needle 5 guided into the puncture needle holding rod 4 of the puncture device 1 pushes the bottom surface of the puncture needle loading chamber 10 of the puncture needle holding rod 4 to a position where it is pushed. In this state, the constricted portion (central recess) 5b of the puncture needle 5 engages with the puncture needle holding claw 26 provided at the entrance of the puncture needle holding rod 4 (FIG. 4B). Thus, when the puncture device 1 is retracted and separated from the puncture needle cartridge 18 with the puncture needle 5 held in the puncture needle holding rod 4 of the puncture device 1, the puncture device 1 punctures the puncture needle 5. The operation of pulling away from the needle cartridge 18 is performed. In the process of pulling the puncture needle away from the puncture needle cartridge, a force is generated to tear the thin resin film in the puncture needle separation groove 5a near the tip of the puncture needle 5. When the operator applies further force against the tearing force (action / reaction force), the puncture needle 5 is pulled away from the main body of the puncture needle cartridge 18 (FIG. 4C).

  Thereafter, in order to puncture from the state of FIG. 4 (c), the puncture needle set lever 8 is tilted by a predetermined angle in the direction of arrow A shown in FIG. 5 (a). Thus, the puncture operation can be prepared. Hereinafter, the operation for preparing the puncturing operation and the puncturing operation will be described.

  First, the puncture depth adjusting ring 40 at the tip of the puncture device 1 is rotated around the axis, and the position of the puncture depth adjusting ring 40 in the axial direction of the puncture device 1 is shifted in advance. The determined puncture depth of the puncture needle 5 is set.

  Then, after loading the puncture needle 5 into the puncture needle holding rod 4 of the puncture device 1, the puncture needle set lever 8 is tilted by a predetermined angle in the direction of arrow A as shown in FIG. The wheel rotation lever portion 8a on the puncture needle set lever 8 abuts on the set pin 12 on the flywheel 11, and moves the flywheel 11 to the set direction side (in the direction of arrow B in FIG. 5A). In this case, the wheel engagement pin 16, which is a connection point between the flywheel 11 and the link 19, is rotated by the rotation of the flywheel 11 and the left side portion of the flywheel set spring 13 shown in the drawing. 13b is pressed so that the flywheel set spring 13 is more compressed, and passes through the maximum compressed state, so that the left side 13b of the flywheel set spring 13 is the right side 13 The wheel engagement pin 16 is approximately parallel to the front end side of the wheel engagement pin stop lever portion 17a on the front end side of the puncture button 17 rotatably supported by an external operation. By contacting, the rotation of the flywheel 11 is locked, and the preparation state for the puncturing operation shown in FIG.

  As described above, while the flywheel 11 rotates by a predetermined angle from the state of FIG. 4C to the puncture preparation state of FIG. 5A, the rotational movement of the flywheel 11 is controlled by the puncture holding rod 4. The puncture needle holding rod 4 connected to the flywheel 11 is slid in the axial direction of the puncture device 1 by the link 19 that converts the puncture device 1 into the slide movement. During this time, the wheel engagement pin 16 on the flywheel 11 and the puncture needle holding rod 4 are connected by the one link 19, and the flywheel 11 is determined by the puncture needle set lever 8 as described above. Therefore, the wheel engagement pin 16 initially rotates in a direction away from the puncture needle holding rod 4, and the puncture needle holding rod 4 is rotated. Sinks into the body of the puncture device 1. Thereafter, as described above, the flywheel 11 further rotates, and the front end of the wheel engagement pin 16 is the front end of the puncture button 17 that is pivotally supported so that the wheel engagement pin stop lever portion 17a. The flywheel 11 stops and the movement of the puncture needle holding rod 4 also stops at the same time. The flywheel 11 receives the rotational force obtained by the urging force of the flywheel set spring 13. The set is completed by the puncture button 17 in the puncture preparation position (FIG. 5A).

Next, a puncturing operation will be described.
In the state of FIG. 5A, when the puncture button 17 is pressed, the puncture button 17 rotates upward, so that the wheel engagement pin stop lever portion 17a pushes the wheel engagement pin 16 rightward in the drawing. The wheel engagement pin 16 moves to the right while slightly rotating the flywheel 11 clockwise, and the wheel engagement pin stop lever portion 17a and the wheel engagement pin 16 are unlocked. As a result, the flywheel 11 that has accumulated the rotational force obtained by the urging force of the flywheel set spring 13 releases the force at a stroke, and the flywheel 11 has an arrow at a stroke around its axis. It rotates in the B direction (counterclockwise).

  At this time, the puncture needle holding rod 4 connected to the flywheel 11 and the link 19 moves linearly (slidably moves) from the inside of the puncture device 1 to the outside, and then the link is generated by the rotation of the flywheel 11. After passing through the position (FIG. 5 (b)) where the puncture needle 5 protrudes from the puncture device 1 to the maximum position, the puncture needle 5 becomes the position on the straight line in the longitudinal direction of the puncture needle holding rod 4. The operation of returning to the puncture device 1 is performed by the inertial force of the flywheel 11. During this return operation, the wheel engagement pin 16 at the tip of the link 19 is pulled from the line connecting the rotation center 8 b of the puncture needle set lever 8 and the rotation center 11 b of the flywheel 11 by the force of the flywheel set spring 13. Until reaching the farthest position and stopping at the position, the puncture needle holding rod 4 is stopped while reciprocating around the position, and the puncture needle holding rod 4 protrudes from the puncture device 1 at this time. In order to prevent the wheel engagement pin 16 from returning to the puncture position, the reverse rotation is implanted in the bottom case 3 so as not to return the movement of the wheel engagement pin 16 toward the puncture position. A prevention claw 20 is provided to prevent the flywheel 11 from moving in the reverse rotation direction by engaging the both (FIG. 5C).

Next, the operation of discarding the puncture needle 5 that has completed the puncture operation will be described.
In the state where the above-described puncturing operation is completed, the puncture needle loading port 9 side of the puncture device 1 is inserted into the puncture device guide portion 21 of the puncture needle cartridge 18. At this time, the puncture needle extraction claw 22 at the distal end portion of the inner cylindrical portion 23 disposed in the puncture device guide portion 21 performs the operation of entering the neck portion 5b of the puncture needle 5, and at the same time, the puncture needle extraction claw 22 The distal end of the inner cylindrical portion 23 having the puncture needle holding claw 26 at the distal end portion of the puncture needle holding rod 4 performs an operation of expanding outward as shown in FIG. 6A, whereby the puncture needle 5 itself Is taken into the inner cylindrical portion 23 (FIG. 6B). Thereafter, the used puncture needle 5 can be held in the puncture needle cartridge 18 by pulling out the puncture device 1. After that, the previous used puncture needle 5 held by the puncture needle cartridge 18 in this way is pushed in with the next used puncture needle 5 held by the puncture device 1 so that the previous one The used puncture needle 5 can be dropped into the disposal box portion 24 of the puncture needle cartridge 18 and the next used puncture needle 5 can be held by the inner cylindrical portion 23 of the puncture needle cartridge 18. Then, by repeating this one after another, the used puncture needle 5 is discarded in the puncture needle cartridge 18, and after all the puncture needles of the cartridge 18 are used, it is disposed in the cartridge 18 or its inner cylindrical portion. The cartridge 18 itself can be discarded after being continuously discarded or gripped in the cartridge 23.

  The puncture needle 5 can be continuously discarded into the puncture needle cartridge 18 by performing this discard operation continuously, that is, successively.

  Further, on the side surface of the portion of the main body of the puncture needle cartridge 18 constituting the disposal box portion 24, as shown in FIG. 3, for example, against blood obtained by puncturing using the puncture device, An insertion port 25 for exhausting the used biometric data measurement sensor that has performed the measurement is formed, and by inserting the used biometric data measurement sensor through the insertion port 25, the used biodata measurement sensor is used. The puncture needle and the used measurement sensor can be discarded together after use.

  In particular, the present invention provides a blood collection puncture device configured to take out puncture needles one by one from a plurality of puncture needles and a puncture needle cartridge for use in measuring blood glucose levels. This is useful for measuring values.
