AI Technical Summary

Technical Problem

In the prior art, medical staff use manual operation of syringes to extract amniotic fluid, which is time-consuming and labor-intensive, and has low work efficiency, increasing the risk of adverse pregnancy outcomes in pregnant women.

Method used

An amniotic fluid puncture needle is designed, including a puncture assembly and a storage assembly. By setting up an arc-shaped handle plate, interference fit of the cannula and cannula, the design of a transparent tube, and the combination of a circular plate and a plug, the function of absorbing amniotic fluid is realized, and the first shunt tube and the second shunt tube are used alternately to ensure the sustainability of the extraction.

Benefits of technology

It improves the efficiency of amniotic fluid extraction, reduces the labor intensity of manual extraction by medical staff, and reduces the risk of adverse pregnancy outcomes in pregnant women.

Abstract

The utility model provides an amniotic fluid puncture needle, and belongs to the technical field of medical instruments. The amniotic fluid puncture needle comprises a puncture assembly and a storage assembly, the puncture assembly comprises a needle head, a connecting tube, a three-way valve, a first shunt tube and a second shunt tube, the connecting tube is connected to the needle head, the storage assembly comprises connectors and a vacuum tube, the first shunt tube and the second shunt tube are both communicated with the connectors, and the vacuum tube is communicated with the first shunt tube and the second shunt tube. By arranging the needle head, the connecting pipe, the three-way valve, the first flow dividing pipe, the second flow dividing pipe, the connector and the vacuum pipe, amniotic fluid in the connecting pipe is divided and guided through the three-way valve, negative pressure suction is conducted in cooperation with the connector and the vacuum pipe, and therefore the first flow dividing pipe and the second flow dividing pipe can be conveniently and alternately used; the extraction continuity is guaranteed, the effect is improved, meanwhile, the manual extraction labor intensity of personnel is relieved, and the risk of the bad pregnancy outcome of the pregnant woman is reduced.
