[0011]

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 with their opening sides facing the substrate. . Specifically, it is constituted by the following modes.

The needle unit holding plate includes a substrate, and a pair of hook-shaped engaging members disposed in parallel on the same surface of the substrate and projecting inward from each other.

In the above structure, the needle unit holding plate is formed in a substantially plate shape, and a flange provided around the opening of the needle unit is inserted and engaged between the engagement pair having a hook-like cross section.
The needle unit is held on the substrate. At this time, since the opening of the needle unit faces the substrate, even when the sterilization 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. The unit can be held.

Therefore, it is possible to prevent a used injection needle from being exposed with a simple and bulky configuration.

The needle unit holding plate may be configured so that the needle unit flange is disengaged from the engagement pair by moving the needle unit perpendicularly to or away from the substrate surface, or May be configured to be moved between the engagement pairs in the direction of the substrate surface to be 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 pairs.

In the above construction, 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. And try to regulate that movement. The projection is appropriately formed so that the flange of the needle unit cannot be pulled out of the engagement pair unless a predetermined force is applied. For example, a configuration is adopted in which the height of the flange of the needle unit is elastically deformed so that it can get over the projection, or the projection is retracted when the projection is pressed by the flange of the needle unit.

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

Preferably, perforations are formed in the substrate.

According to the above arrangement, the substrate holding a plurality of needle units is separated along perforations, so that the substrate can be divided into portions holding an appropriate number of needle units.
It is convenient.
