Problems solved by technology

[0003] It can be seen that due to the various forms of needles, scissors, smaller pliers and larger pliers may be used to disassemble the needle, and there are many types of items that need to be equipped, which is very inconvenient
In addition, when the needle is connected by interference fit or material elasticity, sometimes the connection force is high, and the needle is difficult to pull out

Description

Technical field [0001] The invention relates to the field of clamping and cutting tools, in particular to a needle detaching device. Background technique [0002] Needles are one of the most commonly used items in hospitals, such as scalp needles on infusion sets and needles on syringes. After the medical device is used, the needle needs to be put into the sharps box. The scalp needle is connected to the infusion tube, and scissors are needed to cut the infusion tube so that the scalp needle falls into the sharps box. The needle is connected with the syringe barrel, and the connection methods include interference fit or material elastic connection and threaded connection. In order to avoid needlestick injuries and infection, avoid disassembling the needle by hand. When the needle is connected by interference fit or material elasticity, it is necessary to clamp the needle with pliers, and then pull the needle or syringe barrel forcefully to separate the needle from the syringe ...
