 The present invention relates to a needle unit storage case. Background art

 Conventionally, various syringes have been provided for a patient to perform an insulin injection. For example, the syringe 80 shown in the exploded perspective view of FIG. 1 generally includes a cap 82, a cartridge holder 84, and a syringe body 86, and the cartridge 70 containing the insulin injection solution is used as a cartridge holder. Then, the cartridge holder 84 and the syringe body 86 are connected to each other, and an injection needle 50 is attached and used. The injection needle 50 is a double-edged needle fixed to the needle holder 52, and an inner screw (not shown) on the inner peripheral surface of the needle holder 52 is screwed into an outer screw 85 of the cartridge holder 84. Thus, the proximal end 50b of the injection needle 50 is made to pass through the sealing stopper of the cartridge 70.

 By the way, generally, one insulin cartridge 70 is divided into small portions and used for a plurality of injections. However, the injection needle 50 is replaced with a new one every time to prevent infection.

 The injection needle 50 is generally provided in the form of a needle unit 60. For the new needle unit 60, attach the needle cap 54 to the distal end 50a of the injection needle 50 as shown in the external view of Fig. 2 and the exploded perspective view of Fig. 3 in addition to Fig. 1, for example. The needle holder 52 is housed in the needle cover 56 in a state where it is non-rotatably fitted to the inner peripheral surface of the needle cover 56, and the flange 5 is provided around the opening 57 of the needle cover 56. A sterile seal 59 is adhered to 8 and sealed. The sterile seal 59 is provided with a tab 59a to facilitate peeling.

When attaching the injection needle 50 to the syringe 80, as shown in Fig. 4, hold the gold unit 60 from which the sterile seal 59 has been peeled off with one hand, and use the other hand to hold the cartridge 70 Holding the syringe body 80 with the syringe body 86 attached (more specifically, a cartridge hood holder 84), and moving the needle unit 60 close to the external screw 85 of the cartridge holder 84 of the syringe 80. Turn the needle unit 60 and screw the inner screw of the needle holder 52 in the needle unit 60 to the outer screw 85 of the cartridge holder 84. As a result, injection 50 is attached.

 When injecting, remove the needle cover 56 by pulling it straight in the axial direction, and remove the needle cap 54 before use.

 When the injection is completed, attach the needle cap 54, fit the needle cover 56 into the needle holder 52, turn the needle cover 56 in the opposite direction to the direction when attaching the injection needle, and move the needle 50 into the needle force bar. 56 Remove the needle unit 60 housed in 6 from the syringe 80. As a result, the injection needle 50 is recovered while being stored in the needle cover 56.

 When setting the dose, turn the rotary operation dial 88 provided at the end of the syringe body 86 while looking at the display window 87 of the syringe body 86, as shown in Fig. 5, and ask the attending physician. Set the indicated dosage unit. Then, the injection button 89 of the syringe body 86 is moved to the injection needle 50 side to perform injection.

 By the way, as described above, when attaching and detaching the injection needle 50 to and from the syringe 80, it is necessary to turn the small needle unit 60 while holding it. Some people find it difficult.

 Further, in the used needle unit 60, although the proximal end 5 Ob of the injection needle 50 is exposed from the opening 57, it is dangerous if stored or discarded as it is. Disclosure of the invention

 Therefore, the technical problem to be solved by the present invention is to make it possible to easily perform the operation of attaching and detaching the injection metal f to the syringe and to prevent the injection needle of the used needle unit from being exposed. It is to be.

 The present invention provides a needle unit storage case having the following configuration in order to solve the above technical problem.

The needle unit storage case includes a case body and a lid. The case body has a needle unit on which an injection needle of both swords is stored, and an opening side of the needle unit. A plurality of needle unit engagement holes are formed which can be inserted in a non-rotatable manner in the upward direction. The lid covers above the unit engagement hole.

 In the above configuration, the needle unit is inserted into the needle unit engaging hole of the case body with the opening side facing upward, and the upper part is covered with a lid. Thus, the needle unit is stored in the needle unit storage case with the opening side covered by the lid. In the above configuration, the needle unit engagement hole of the needle unit storage case can be used for an operation of attaching and detaching the injection needle to and from the injector. When installing the injection needle, insert the needle unit into the needle unit engagement hole of the needle unit storage case, and hold it with the base end of the injection needle exposed upward. Then, while holding down the needle unit storage case with one hand, turn the needle attachment part of the syringe close to the needle unit with the other hand and turn it. Since the needle unit is engaged with the needle unit engagement hole and does not rotate, the injection needle can be attached to the syringe by the relative rotation between the needle unit and the syringe. To remove the injection needle, simply rotate the syringe in the opposite direction.

 According to the above configuration, a relatively simple operation of holding down the needle unit storage case and turning the syringe while holding the syringe can be used to attach and detach the injection needle, and a fine operation of pinching and turning a small injection needle unit with a fingertip. Becomes unnecessary. In addition, the operation of attaching and detaching a needle to and from a syringe can be performed using a needle unit storage case that stores unused needle units to be attached to the syringe, which is convenient.

 The used needle unit is removed from the syringe, and is inserted into the needle unit engaging hole of the needle unit storage case. By closing the cover, the proximal end of the injection needle exposed from the opening is covered with the cover. Since the injection needle is not exposed, it is safely held in the needle unit storage case.

 Therefore, the operation of attaching and detaching the injection needle to and from the syringe can be easily performed, and the injection needle of the used needle unit can be prevented from being exposed. In addition, since the needle units can be stored in the needle unit storage case in an aligned state, it is easy to check the number of unused and used needle units.

 The needle unit storage case may be configured so that a part of the stored needle unit on the side opposite to the opening side is exposed to the outside, thereby reducing the size.

Preferably, the case body includes a needle unit inserted into the needle unit engaging hole. Completely stored inside.

 According to the above configuration, the circumference of the needle unit inserted into the needle unit engaging hole is completely covered by the case body and the lid, and the needle unit can be more safely held in the needle unit storage case. It becomes possible. BRIEF DESCRIPTION OF THE FIGURES

 Hereinafter, a needle unit storage case 10 according to an embodiment of the present invention will be described with reference to FIGS.

 As shown in the perspective view of FIG. 6, the needle unit storage case 10 has a needle unit engagement hole 3 5 (see FIG. 6) for receiving the needle unit 60 on the upper surface of a generally rectangular parallelepiped case body 30.

7 and FIG. 8).

 More specifically, as shown in the cross-sectional view of FIG. 7, the case main body 30 is a resin member in which a box-shaped lower part 38 and a substantially plate-shaped upper part 32 are locked. A locking groove 39 is formed in the upper part of the inner periphery of the lower part 38, and a hook-shaped locking leg 36 is projected from the lower surface of the upper part 32, and a projection of the locking leg 36 is formed. 37 is locked in the locking groove 39 of the lower part 38 so that the upper part 32 and the lower part 38 are connected.

A large number of needle unit engagement holes 35 are formed in the upper part 32, and the needle unit 60 is inserted into the needle unit engagement hole 35 with its opening 57 side facing upward. The flange 58 is held in engagement with the upper surface of the upper part 32. You.

 More specifically, the needle unit engagement hole 35 is formed in a shape obtained by transferring the cylindrical surface of the needle unit 60 to the substantially cylindrical inner peripheral surface of the cylindrical portion 34 of the upper part 32. To be fitted to the cylindrical surface of That is, a groove extending in the axial direction is formed in the cylindrical surface of the needle unit 60, and the needle unit is formed on the inner peripheral surface of the needle unit engagement hole 35, as shown in the sectional view of FIG. A projection 35a that engages with the groove of the cylindrical surface 60 is formed. The needle unit 60 can be inserted into the needle unit engagement hole 35 with the opening 57 side facing upward, and the inserted needle unit 60 is inserted into the groove of the cylindrical surface. The projections 35a of the 35 are engaged so that rotation is prevented.

 The left and right edges of the upper part 32 protrude outward from the lower part 38, and the engaging groove 24 of the lid 20 engages with this protruding part so that the lid 20 can be disengaged from the case body 3. By sliding along the upper surface of the needle unit 0, the lid 20 covers the upper part of the needle unit 60 held in the needle unit engagement hole 35. A concave portion 26 is formed on the lower surface side of the lid body 22 so that when the lid 20 is closed, it does not interfere with the flange 58 or the sterile seal 59 of the needle unit 60.

 Unused needles are sealed in the needle unit engagement holes 35 of the needle unit storage case 10 with the sterile seal 59 facing upward. When attaching the needle 50 to the syringe 80, first remove the unused needle unit 60 from the needle unit engaging hole 35 of the needle unit storage case 10, and peel off the sterile seal 59. After that, the needle unit 60 is inserted again into the needle unit storage case hole 35, and the needle unit 60 is opened with the proximal end 50b of the injection needle 50 exposed upward from the opening 57 of the needle unit 60. In the needle unit storage case 10.

Next, hold the needle unit storage case 10 with one hand, hold the syringe 80 vertically with the other hand, and attach the external screw 85 provided at the end of the cartridge holder 84 of the syringe 80 to the injection needle 5. Insert the base unit 50 into the ft unit 60 with the base end 50b exposed upward and turn the syringe 80. At this time, the needle unit 60 engages with the needle unit engagement hole 35 and rotates. Is prevented, so that the outer screw 84 of the syringe 80 can be screwed into the inner screw of the needle holder 52 of the needle unit 60. When the screw is completely screwed, the syringe 80 is straightened To lift. At this time, since the needle unit 60 does not engage with the needle unit engagement hole 35 in the axial direction, the needle unit 60 is attached to the syringe 80 and the needle unit 60 is inserted through the needle unit engagement hole 35. Removed. When performing injection, the needle cover 58 of the needle unit 60 and the needle cap 54 are removed to expose the injection needle 50 for use.
