PROBLEM TO BE SOLVED: To provide a thrust preventing instrument for safely handling a purcataneous injection needle, relatively inexpensive, easy to manufacture and suitable for a single usage. SOLUTION: The thrust preventing instrument is formed of two plate members (F, D) arranged so as to be overlapped with each other and mutually fixed by link members (B, C, E, A) and constituted so as to be capable of being changed from a close contact state wherein two plate members are pushed one another to a spaced-apart state wherein two plate members are spaced apart from each other and the space surrounded by the link members is formed between the plate members and the part (17) thrust in the skin of a needle can be housed in the space when the needle is pulled off from the skin. |
