Detailed Description
As shown in fig. 1, the self-cleaning injection needle of the present invention includes a base 10, a needle body 20 and a self-cleaning assembly 30. The needle body 20 is fixedly connected with the base 10, and the needle body 20 is perpendicular to the base 20. The self-cleaning assembly 30 is arranged around the needle body 20, and the self-cleaning assembly 30 is elastically connected with the base 10. When the needle body 20 is inserted, the self-cleaning component 30 is compressed towards the base 10 under the pressure; when the needle body 20 is pulled out, the self-cleaning component 30 can automatically return to the direction far away from the base 10, and in the process, the needle body 20 can be cleaned and disinfected through the contact between the self-cleaning component 30 and the needle body 20.
