Hidden self-destruction needle head

Abstract

The invention relates to the technical field of injection needles, in particular to a hidden self-destruction needle, which comprises an injection needle and a needle hiding device, the needle hiding device comprises a needle hiding cap, a protective cap, a guide sleeve and an elastic element, a clamping groove set is formed in the guide sleeve and comprises a guide groove and a locking groove, of which the inner ends are communicated with each other; a tooth column is arranged on the protective cap and is positioned in the guide groove; the first inclined plane matching structure and the second inclined plane matching structure are both used for enabling the protective cap to rotate in the same direction while axially displacing, the locking groove is used for blocking the tooth column in the locking groove, so that the protective cap cannot axially displace inwards. The hidden self-destruction needle head can shield the injection needle head, and the hiding function of the injection needle head is achieved; meanwhile, after being used once, the syringe needle can be automatically locked and hidden again, so that the syringe needle is prevented from being repeatedly used, and self-destruction is realized. In addition, the instrument does not need to provide additional destroying actions manually, operation is convenient, the safety performance is greatly improved, and the market prospect is good.

Description

technical field [0001] The invention relates to the technical field of injection needles, in particular to a hidden self-destruct needle. Background technique [0002] At present, injection needles are usually protected by a needle cover to prevent accidental stabbing by staff and damage to injection needles due to collisions. Such injection needles mainly have the following defects: [0003] 1) During the injection process, the injection needle is directly exposed to the outside world, which is likely to cause the patient's sense of fear and psychological pressure, which is not conducive to the smooth progress of the injection, especially when injecting children, it is common for children to have a sense of fear; [0004] 2) After the injection is completed, the operator often does not put the needle cover on the injection needle again, and the injection needle is directly exposed to the outside world, which will lead to the possibility of stabbing the relevant personnel an...

Problems solved by technology

[0003] 1) During the injection process, the injection needle is directly exposed to the outside world, which is likely to cause the patient's sense of fear and psychological pressure, which is not conducive to the smooth progress of the injection, especially when injecting children, it is common for children to have a sense of fear;

[0004] 2) After the injection is completed, the operator often does not put the needle cover on the injection needle again, and the injection needle is directly exposed to the outside world, which will lead to the possibility of stabbing the relevant personnel and causing cross-infection;

[0005] 3) After the injection is completed, the injection needle cannot self-destruct, and there is a possibility of being reused, which may easily cause the spread of the disease
