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

Embodiment

[0020] Example: such as Figure 1-4 As shown, the present invention provides a specific embodiment of a self-destructing safety medical needle, which includes: a sleeve 10 having an inner chamber 12, a needle base 20 capable of reciprocating movement in the inner chamber 12 and having a needle 22, and The locking head 28 of the needle base 20 interlocking and the conduit 30 communicating with the interior of the locking head 28, wherein the sleeve 10 is provided with a blocking block 120 and a locking block 122 in the inner cavity 12, and the needle base 20 is provided with a corresponding There is a limiting portion 24 abutting against the blocking block 120 , and an elastically deformable locking portion 26 interlocking with the locking block 122 . The blocking block 120 prevents the needle hub 20 from continuing to move, and the locking block 122 prevents the needle hub 20 from moving backward. The locking portion 26 is preferably a pair of elastically expandable expansion...

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...
