Self-destroying type transfusion syringe

Abstract

The invention discloses a self-destroying type transfusion syringe in the technical field of medical tools. The self-destroying type transfusion syringe includes a transfusion syringe body, a first sleeve, a lifting mechanism and a second sleeve sleeving the first sleeve; the transfusion syringe body is arranged in the first sleeve, and a syringe needle of the transfusion syringe body stretches out of the second sleeve; a transverse through groove and a connecting groove are formed in the second sleeve, the right side of the transverse through groove is communicated with the connecting groove,a connecting fin penetrates through the first sleeve and is slidingly connected into the transverse through groove and the connecting groove, and the transverse through groove includes a second transverse through groove body and a first transverse through groove body; the wall of the second sleeve is internally provided with an interlayer, a sponge block and a glue storage bag containing glue arearranged at the bottom of the lifting mechanism, the glue storage bag is positioned on the right side of the sponge block, and the outer wall of the first sleeve is provided with a supporting block used for supporting the lifting mechanism. The first transverse through groove is longer than the supporting block, and a transfusion pipe is fixedly connected with the first sleeve. Self-destroying ofthe transfusion syringe can be achieved.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a self-destructing infusion needle. Background technique [0002] The intravenous infusion needle is one of the most commonly used and simplest medical devices. The infusion set includes an infusion needle, a connecting seat and an infusion tube that are fixedly connected in sequence. The needle sticks into the skin. With the advancement of technology, the infusion needle has been developed from the original multiple disinfection and repeated use method to the current one-time use method. However, the existing disposable infusion needles have no self-destruct function, and can be reused after a little treatment. Once reused, it is very easy to cause cross-infection of blood diseases such as AIDS and liver disease or other diseases, thereby causing great harm to society. In addition, the needles after use have no protective measures and are exposed outside, which will...

Problems solved by technology

However, the existing disposable infusion needles have no self-destruct function, and can be reused after a little treatment. Once reused, it is very easy to cause cross-infection of blood diseases such as AIDS and liver disease or other diseases, thereby causing great harm to society. In addition, the used needles have no protective measures and are exposed outside, which will also bring inconvenience to the disposal of medical waste. The needles will also pierce the skin and cause cross-infection

[0003] In view of the above problems, the Chinese patent application No. CN201520496439.8 discloses "a self-destructing infusion needle that is easy to use". This patent is provided with an annular groove on the needle head and an elastic limit clamp on the sliding sheath. And the limit protrusion, after the infusion is completed, the limit protrusion clamps the annular groove under the action of the elastic limit clamp, so that the needle cannot advance and retreat, but this patent only fixes the infusion needle on the sliding sheath Inside, the structure of the infusion needle is complete, and the infusion needle can be taken out by cutting the sliding sheath, and it can be used for secondary use after a little treatment, and the purpose of self-destruction cannot be achieved
