Abstract

The invention relates to a thrombolytic agent syringe, and relates to the technical field of medical equipment so as to solve the technical problem that operation of an existing syringe is inconvenient. The thrombolytic agent syringe includes a syringe barrel, a push rod and a piston installed in the syringe barrel. The front end of the syringe barrel is provided with a needle connector connectedwith a needle for injection, the push rod is fixedly connected with the piston, a rod body of the push rod stretches backwards to the outside of the syringe barrel, the front end of the piston is fixedly provided with an integrally closed saline storage chamber, the saline storage chamber is filled with normal saline, and the front end of the piston is fixedly provided with a spike which can pierce the wall of the saline storage chamber. The provided syringe can reduce the injection cost of a thrombolytic agent.

Description

technical field [0001] The invention relates to medical equipment technology, in particular to a technology of a thrombolytic drug injector. Background technique [0002] In the treatment of acute ischemic stroke (cerebral infarction), it is necessary to inject thrombolytic agents for patients. When injecting thrombolytic agents, an extension tube is connected between the syringe and the needle, and the thrombolytic agents in the extension tube are included in the total amount of drugs Therefore, after the thrombolytic agent in the syringe is pushed out, the syringe needs to be pulled out from the extension tube, and another syringe filled with normal saline is connected to the extension tube, and a small amount of normal saline is injected. The remaining drug in the extension tube is injected together by injection. This bolus injection of thrombolytic agent requires two conventional syringes, the former one is used for bolus injection and the latter one is used for locking...
