Auto-disposal safe medical needle

Abstract

The invention discloses an auto-disposal safe medical needle, which comprises a sleeve, a needle seat, a lock buckle head and a catheter, wherein the sleeve is provided with an inner cavity; the needle seat can do reciprocating movement in the inner cavity, and is provided with a needle head; the lock buckle head is mutually buckled with the needle seat; the catheter is communicated with the inside of the lock buckle head; a blocking block and a lock buckle block are arranged in the inner cavity of the sleeve; the needle seat is correspondingly provided with a position limiting part and a locking part; the position limiting part is in butted matching with the blocking block; and the locking part is in interlocking matching with the lock buckle block and can deform. The auto-disposal safe medical needle has the advantages that the cross infection among patients can be avoided; the secondary use of the medical needle and the puncture injury on work personnel after the use or in the disposal process can also be avoided; meanwhile, the auto-disposal effect can be achieved; and the deliberate recycle of the medical needle can be prevented.

Description

technical field [0001] The invention relates to a self-destruction safety medical needle. Background technique [0002] Medical needles, which are used for infusion or blood collection, are commonly used medical devices. Ordinary medical infusion needles can be reused. If they are not effectively cleaned and disinfected, they will easily cause cross-infection among patients. In order to solve this problem, disposable Infusion needles have been widely used, but this disposable infusion needle is only required at the management system level to be used in a single use. At the same time, in order to avoid the secondary use of infusion needles and the stabbing of staff after use or in the process of destruction, causing serious consequences of virus cross-infection, safety infusion needles have been widely used in the medical field, and the medical regulations of many countries have more clearly stipulated Safety infusion needles must be used. In recent years, many kinds of dis...

Problems solved by technology

[0002] Medical needles, which are used for infusion or blood collection, are commonly used medical devices. Ordinary medical infusion needles can be reused. If they are not cleaned and disinfected effectively, it is easy to cause cross-infection among patients. In order to solve this problem, disposable Infusion needles are widely used, but this kind of disposable infusion needle is only required to be used once at the management system level

At the same time, in order to avoid the secondary use of infusion needles and the stabbing of staff after use or in the process of destruction, causing serious consequences of virus cross-infection, safety infusion needles have been widely used in the medical field, and the medical regulations of many countries have more clearly stipulated Safety infusion needles must be used

In recent years, people have developed many kinds of disposable safety infusion needles with automatic destruction devices, which technically guarantee the function of only one-time use, but the structure is complicated and the cost is high
