Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protector for a syringe, and more particularly to a protector for a syringe which protects a finger from the needle when the needle is housed in a sheath.

[0002]

2. Description of the Related Art A syringe has an injection needle housed in a sheath when not in use to protect a finger. Then, the sheath is removed at the time of use, and the injection needle is put into the sheath again after injection or blood collection.

Since the opening of the sheath is narrow when the needle is stored in the sheath, it is easy for the finger holding the sheath to pass and be struck by the tip of the needle. In this case, if the patient or blood sample recipient carries the pathogen, secondary infection will occur.

Therefore, conventionally, in the case of injection, after use, in the case of blood collection, the collected blood is transferred to another container (for example, a test tube) and then immediately stored in a dust box or in a furnace at 1200 ° C. or higher. It is heated to a high temperature to melt the injection needle and take measures to kill the pathogen. Particularly, in the latter method, the device becomes heavy and large-scaled, and it is not portable, and the cost is high.
