The present invention relates to a needle unit holding plate. Background art

Conventionally, various syringes have been provided for a patient to perform 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 liquid is forced into a cartridge. It is inserted into the holder 84, the cartridge holder 84 and the syringe body 86 are connected, and the 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 50 is passed 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, for example, Fig. 1, the ^ diagram in Fig. 2 and the exploded perspective view in Fig. 3. The needle holder 52 is accommodated 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 is provided around the opening 57 of the needle cover 56. A sterile seal 59 is adhered to the flange 58 to seal it. The sterile seal 59 is provided with a tab 59a to facilitate peeling.

When attaching the injection barrel 50 to the syringe 80, as shown in Fig. 4, hold the needle 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 With a syringe unit 80 (specifically, a cartridge holder 84) to which the needle unit 86 is connected, and the needle unit 60 is brought close to the external screw 85 of the cartridge holder 84 of the syringe 80, and the needle unit is closed. Turn the knob 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. Thus, the injection needle 50 is attached.

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

When the injection is completed, attach the ^ "cap 54, fit the needle cover 56 to the needle holder 52, turn the needle cover 56 in the opposite direction to the direction when mounting the injection needle, and insert the injection needle 50 The needle unit 6◦ stored in the force bar 56 is removed from the syringe 80. As a result, the injection needle 50 is recovered while being stored in the needle cover 56.

Set the indicated dosage unit. Then, the injection button 89 of the syringe body 86 is moved toward the injection needle 50 to perform injection.

By the way, since the proximal end 50b of the injection needle 50 is exposed from the opening 57 of the needle unit 60 from which the sterile seal 59 has been removed, the used needle unit 60 is generally resistant to use. Discard in a pierceable collection container. However, since this collection container accommodates a certain number of needle units 60, it is large, bulky, and inconvenient to carry. Disclosure of the invention

Therefore, the technical problem to be solved by the present invention is to prevent the used injection or the exposure of the used injection in a simple and bulky manner.

The present invention provides a needle unit holding plate having the following configuration in order to solve the above technical problems.

The basic feature of the needle unit holding plate is that the substrate is provided with a needle unit engaging portion for detachably holding a plurality of needle units in a state where the opening side faces the substrate. Specifically, it is constituted by the following aspects. The needle unit holding plate includes a substrate, and a pair of hook-shaped engaging members disposed on the same surface of the substrate in parallel with each other and projecting inward from each other.

In the above configuration, the needle unit holding plate is formed in a substantially plate shape, and a flange provided around an opening portion of the needle unit is inserted between the engagement pairs having a hook-shaped cross section to be engaged, and the needle unit is provided. Holding the substrate on the substrate. At this time, since the opening of the needle unit faces the substrate, even if the sterile seal is removed and the injection needle is exposed from the opening, the needle is covered with the substrate and is not exposed to the outside. Unit can be held. Therefore, it is possible to prevent the used injection needle from being exposed with a simple and bulky configuration.

The needle unit holding plate may be configured such that the needle unit is disengaged from the engagement pair by moving the needle unit in a direction perpendicular to the substrate surface, or the needle unit flange is connected to the substrate unit. It may be configured to be moved between the engagement pair in the surface direction and inserted and removed.

In the latter configuration, preferably, the needle / needle unit holding plate further includes a projection on the substrate and / or the engagement pair, which protrudes into a space formed between the engagement pair.

In the above configuration, the projection is arranged near the flange of the needle unit held between the engagement pair, and when the flange of the needle unit moves between the engagement pair, the projection interferes with the flange of the needle unit. Try to regulate movement. The projection is formed appropriately so that the flange of the needle unit cannot be inserted or removed from between the engagement pair unless a predetermined force or more is applied. For example, the height of the flange of the needle unit is set to a value that allows the flange to elastically deform to get over the projection, or the projection is retracted when pressed by the flange of the needle unit.

Therefore, with a simple configuration, it is possible to prevent the needle cover from easily falling out of the needle unit holding plate.
