Disposable self-destructed syringe

Abstract

The disposable self-destructed syringe includes a needle, a cylinder, a core rod, a ratchet slot, a back limiting step, a mounting hole, one back stopping part, a back stopping pike, a ratchet, a sealing stop, and a reciprocating part. The disposable self-destructed syringe has reliable convenient use and is self-destructed after once use.

Description

technical field [0001] The invention relates to a one-time use self-destruction syringe, which belongs to medical syringes. Background technique [0002] At present, the disposable aseptic syringes widely used in hospitals at home and abroad do not fully have the characteristics of disposable use due to their structure, and people only need to adjust the syringes slightly to reuse them. . For example, some self-destructing syringes known both at home and abroad mostly destroy the seal of the piston when the syringe injects medicinal liquid, so that the syringe can only be used once. But as long as the piston and the core rod are not pressed to the bottom when injecting (that is, as long as there is a little liquid medicine left), the piston cannot be damaged and can be used repeatedly. In order to overcome the above deficiencies, our company declared a utility model disposable self-destructing syringe to the State Intellectual Property Office on June 18, 2003. Application...

Problems solved by technology

However, there are still shortcomings in clinical use. Since the exhaust was not designed at that time, the air drawn into the syringe barrel could not be exhausted, which brought great inconvenience to medical staff. Another disadvantage is the small-capacity immune syringe and insulin Syringe, which requires very little liquid remaining in the syringe, and requires the needle tip of the small-capacity syringe to be glued directly to the syringe barrel to reduce the residual amount
