  First, when the puncture needle replacement jig 107 is inserted from the distal end portion 103 of the puncture device 101, the puncture needle 201 is integrated in series by pushing the replacement jig pressing portion 502 as shown in FIG. One pushes the entire puncture needle cartridge 200 through the puncture needle locking member 202. In this way, by the mounting operation of the replacement jig 107, the firing spring 403 formed of an elastic member such as a compression spring that is a means for urging the puncture needle cartridge 200 toward the puncture unit 103, which is the distal end portion of the puncture device 101. Against the reaction force, a set claw portion 404 formed at one end of the puncture button 102 and a set claw engagement portion 206 formed on the surface of the puncture needle cartridge 200 pass through the tip of the set claw portion 404. By engaging, the setting operation is completed without allowing the puncture needle cartridge 200 to return to the initial position again by the return force of the firing spring 403.

  Once the puncture needle cartridge 200 is set in this manner, the puncture button 102 is operated to lock the set claw portion 404 that has locked the puncture needle cartridge 200 and the set claw engagement portion 206. Is released. By this operation, the puncture needle cartridge 200 moves linearly on its axis by the restoring force of the firing spring 403, and puncture is performed while the distal end portion of the puncture needle 201 is fixed in the puncture needle cartridge 200. The puncture part 103 at the tip of the instrument 101 is reached at once. By this operation, the puncture needle 201 passes through the puncture portion 103 without being pulled out while being held by the puncture needle retaining elastic member 205 that holds the puncture needle 201. Thereafter, the puncture needle 201 is returned to a position where the original puncture needle cartridge 200 is not punctured and set by the reaction force of the firing spring 403, and thus a series of puncture operations are completed.

  In addition, as described above, the puncture needle 201 fixed in the puncture needle cartridge 200 is ejected by holding only the first puncture needle 201 that has been punctured and ejected by the replacement jig 107, as described above. The needle 201 is reliably advanced. At the time of the progressive operation of the puncture needle 201, the distal end portion of the puncture needle retaining elastic member 205 is the same as the distal end of the replacement jig pressing portion 502 as shown in FIG. By engaging with the elastic member 205, the engaged state with the puncture needle 201 is released, and at the same time, the tip of the exchange jig return member 503 provided on the exchange jig 107 side is attached to the surface of the puncture needle 201. The indented portion 204 is gripped. Thereafter, when an operation for extracting the replacement jig 107 is performed, the puncture needle 201 is extracted from the puncture needle cartridge 200.

  In this way, the group of puncture needles 201 connected in series by their own elastic characteristics tends to move while sliding integrally within the puncture needle cartridge 200. At this time, a load is applied to the puncture needle 201 in a direction against the binding force of the puncture needle 201 by the holding force of the puncture needle locking member 202. Therefore, in order to prevent the serial connection of the puncture needle 201 from being removed by this load, the shape of the elastic deformation portion 304 formed by means such as injection molding of the puncture needle 201 to elastically connect, This can be realized by adjusting the bending allowance to an optimal size that can secure the retaining strength.

  Further, in this way, when the puncture needle 201 that has been punctured is replaced and removed by the replacement jig 107, a group of puncture needles 201 in the puncture needle cartridge 200 can be sequentially fed to the distal end side of the puncture device 101. .

  In addition, the puncture needle cartridge 200 is supported as a guide member for the rectilinear movement by supporting the puncture needle 201 at two or more locations in the longitudinal direction of the puncture needle 201 in order to reduce blurring during the linear operation of the puncture needle 201. It functions.

  Moreover, when changing the puncture depth of the puncture needle 201, it is achieved by sliding the puncture depth adjusting unit 106 in the longitudinal direction of the main body of the puncture device 101. In addition to the slide mechanism as described here, the puncture depth adjusting unit 106 can be rotated by, for example, a rotating mechanism such as a screw mechanism provided on a ring-shaped member engaged with the puncture needle cartridge stopper 402. Even if the operation is performed on the outer peripheral portion of the puncture device 101, the puncture depth can be changed.

  Next, an operation of loading a new puncture needle 201 after the predetermined number of puncture needles 201 has been used in the puncture needle cartridge 200 will be described.

  Initially, it has been described that the puncture needle cartridge 200 is built in the puncture device 101. However, when the puncture needle 201 has been used up, the puncture needle cartridge 200 is removed by removing the cap 105 behind the puncture device 101. The rear end of 200 is exposed. The puncture needle cartridge 200 is loaded from the puncture needle head cap 301 side in a state where a plurality of puncture needles 201 are connected as shown in FIG. At this time, the connected puncture needles 201 are continuously pushed in by hand, and finally, the loading operation is completed by pushing in until the main body rear end cap 105 abuts against the retaining elastic member 205 of the puncture needle 201.

  By repeating the above operation, the puncture operation performed at the time of measuring the blood sugar level or the like can be performed continuously, and the operator presses the puncture button 102 after a predetermined operation of the replacement jig 107, so that FIG. As shown in FIG. 5, the puncture operation can be performed while lightly pressing the blood collection unit such as the fingertip or arm with the puncture unit 103, and a series of blood collection operations can be performed.

  The puncture device set according to Embodiment 1 of the present invention as described above includes a puncture needle cartridge 200 for arranging a plurality of puncture needles 201 in series inside a cylindrical puncture device 101, and the puncture needle. A puncture needle cartridge stopper 402 for locking the cartridge 200 at a predetermined position in its axial direction, a firing spring 403 for urging the puncture needle cartridge 200 in one direction, and a puncture operation that continues after the puncture of the puncture needle In order to enter, the puncture needle cartridge is provided at the puncture position, and the used puncture needle can be discarded, and the puncture replacement jig 107 is disposed. Since the puncture needle is safely discarded and the puncture position is set for the subsequent puncture operation, the puncture operation can be performed continuously with a simple operation. Can, it is possible to provide a more highly safe puncture device.

  In the first embodiment, the side of the main body case 101 of the puncture device 100 is shown in FIG. 1 so that the remaining amount of the puncture needle cartridge 200 can be discriminated until the puncture needle 201 is used up while being sequentially fed. Such a remaining amount confirmation window 104 is provided so that the remaining number of puncture needles 19 can be easily confirmed from the outside. For confirmation of this remaining amount, as shown in FIG. It is possible to write the serial number 303 or the like on 201 by printing or engraving. It is also possible to color each puncture needle 201 or to color the last one such as red.
