Abstract

The invention relates to a matched needle for a safety insulin pen. The matched needle comprises a needle seat fixedly provided with a needle tube and a safety protection sleeve. The needle seat comprises a pen cap part in threaded fit with the end of the insulin pen and a sliding joint part coaxially and fixedly arranged at the front end of the pen cap part. The sliding joint part is cylindrical, the front end of the needle tube stretches out of the end of the sliding joint part, the safety protection sleeve is a bucket-shaped component, the inner diameter of the safety protection sleeve is in clearance fit with the sliding joint part, and the rear end of the safety protection sleeve is open. A needle hole allowing a needle tip to penetrate out is formed in the position, corresponding to the needle tube, of the front end of the safety protection sleeve. According to the matched needle for the safety insulin pen, the safety protection sleeve is arranged, after the matched needle for the insulin pen is used, the safety protection sleeve slides out forwards to cover the exposed needle tip, therefore, puncture is avoided, and the risk of cross infection is reduced.
