Technical Field

[0001] The utility model belongs to the technical field of medical device recycling, and in particular relates to an automatic separation, bending and curling recycling device for a needle of an intravenous infusion device. Background Art

[0002] An IV infusion set is a common medical tool that uses a needle to inhale or pump out gas or liquid. It is used in many fields such as medicine and experiments. To avoid cross infection, syringes in any scenario are disposable and are not allowed to be reused. The medical department has put forward relevant requirements and regulations in this regard. The needles and syringes of medical syringes should be collected and destroyed and recycled by designated units, and should not be discarded or stored anywhere.

[0003] At present, medical staff mainly separate the needles of intravenous infusion sets by cutting the hose with scissors to separate the needles and hoses, and then put them into corresponding recycling bins. In this process, the hands of medical staff are easily stabbed by sharp needles, causing cross infection. In addition, the method of cutting the hose with scissors cannot completely separate the metal needle and the plastic part of the hose, and there is also the problem of incomplete separation. Therefore, at this stage, an automatic device that can separate and recycle needles is needed, which can not only avoid needlestick injuries, but also completely separate the plastic part of the hose and the metal needle of the intravenous infusion set.
