Safety needle group capable of being automatically sleeved with protective sleeve

Abstract

The present invention provides a safety needle set that can automatically fit the sheath, which is used to set a needle assembly with a needle head. The safety needle set has a clamping lower seat and a clamping upper seat that are combined with each other. The clamp upper seat and the clamp lower seat are jointly arranged above and below the needle assembly, and a sheath is sandwiched between the clamp upper seat and the clamp lower seat, and the sheath is set outside the needle head and It is slidably clamped between the clamp upper seat and the clamp lower seat, and a spring is sandwiched between the sheath and the clamp upper seat and the clamp lower seat, and the sheath is automatically pushed by the elastic force of the spring , so that the sheath is sheathed on the outside of the needle head, and the sheath will cover and lock the needle head when it slides forward to a certain position, so that it can no longer be exposed for use.

Description

technical field [0001] The present invention relates to a safety needle set that can automatically fit the sheath, in particular to a safety needle set that uses the sheath to automatically push outwards to block the used needles from the outside world, thereby preventing related personnel from touching the needle set later In addition, the sheath automatically moves outward after the needle is used for injection and is positioned correctly. The sheath has no possibility of retraction, which can prevent the used needle from being used again. Background technique [0002] Generally, the use of the traditional needle set is to remove the protective needle cover at the front end of the needle set, and then insert the needle into the human body to inject the medicinal solution, and make the butterfly wing stick to the surface of the injection site of the human body. Withdraw the needle. Since the needle has been used, the operator must carefully put the needle back into the ori...

Problems solved by technology

[0003] However, the general needle group is mostly used for drip injection. Since the drip injection takes several hours, it is characterized by: the needle of the needle group may be displaced, the needle may be missed, and the needle needs to be pulled out halfway to re-inject. It has been contaminated afterwards, so when the needle is pulled out of the body, the original protective needle cover must be put back, otherwise the used needle may stab the staff and cause the problem of infection

However, the original injector and the needle puller may not be the same person, and the defect that the original protective needle cover cannot be found often occurs
