Micro-syringe as a result of the high frequency of clinical use, direct contact with patients, the failure of its equipment will have a direct impact on the patient's disease status. Researchers in this paper, by simulating the test fluid, electrical safety testing and analysis of statistical methods such as maintenance records, consider six kinds of common injection pump, in terms of performance, safety and the failure rate of three performance. Compared the performance analysis, summarized the various types of injection pump characteristics, researchers make suggestions to clinical departments, equipment procurement and equipment management departments for usage and improvement.

An auto-retractable self-disable safety syringe is introduced. The product mainly consists of barrel, plunger hander, needle holder, spring and needle cap. After injection, the clasp on top of plunger hander will be jammed with the outshoot of needle holder, meanwhile, the plunger hander tip expands the stop structure and consequently the compression spring pulls the needle and needle holder back into plunger hander. The technical parameters of present syringe such as break force, needle holder push out force and plunger hander lock force are very stable while working. With simple structure, reasonable design, easy manufacture and assemble, this product can been widely used in relevant area.
