Description

  The present invention relates to a pen-type syringe mounting aid and a carrying case for a pen-type syringe, and in particular, a pen-type syringe that can be suitably used for attaching a needle before use in a pen-type syringe and a recapping operation after use. The present invention relates to a mounting aid and a carrying case.

  The pen-type syringe is a syringe used when a diabetic patient performing insulin therapy injects an insulin preparation into the body. There are two types of pen-type syringes, a cartridge type and a disposable type. In a cartridge-type pen-type syringe, a special injection needle formed in a cap shape built into the needle case is screwed into the tip of a pen-type cartridge containing a predetermined amount of insulin preparation, and is removed from the needle case. Then, the insulin preparation is injected into the body by inserting a needle into the treatment site. Then, after injection by the pen-type syringe, the injection needle is removed from the pen-type cartridge and discarded as medical waste. The removal of the injection needle is performed by covering the injection needle with the needle case and covering the injection needle into the needle case. This act of covering the injection needle is referred to as a recap operation. In the recap operation, a pen-type syringe mounting aid may be used to prevent an infection from occurring due to a needle stick accident.

  As shown in FIG. 7, in the conventional attachment assist tool 104 for the pen-type syringe 110, a step 102 a that holds the needle case 113 obliquely is formed at the bottom of the packaging container 102 that houses the pen-type syringe 110. It was. Therefore, by inserting the injection needle 112 into the cap-shaped needle case 113 held obliquely after the injection of the pen-type syringe 110, the person who performed the injection does not hold the needle case 113 by hand. 110 can be recapped.
