Problems solved by technology

[0003] However, in actual use, the above-mentioned device can only realize the function of anti-reflux. When the air traction function is performed, due to the instability of the air pressure, it is likely to cause excessive pressure of amniotic fluid absorption and cause side effects, which has great limitations.

Abstract

The invention discloses a backflow prevention amniotic fluid aspirator special for the obstetrics and gynecology department. The backflow prevention amniotic fluid aspirator comprises a bottom hollowshell and a top hollow hell, main hollow structures are both arranged in the centers of the upper surface of the bottom hollow shell and the lower surface of the top hollow shell, the inner side of the upper surface of the bottom hollow shell is connected with the outer side of the lower surface of the top hollow shell through a main threaded structure, the bottom of the bottom hollow shell is installed on the upper surface of a supporting baseboard, and a turbine mounting space is arranged at the portion, located over the main hollow structure, inside the top hollow shell. Aerodynamics is utilized, so that the device has the adsorption capacity, and therefore amniotic fluid is adsorbed; meanwhile, the device is provided with an amniotic fluid backflow prevention mechanism, and the occurrence that the amniotic fluid flows back due to the liquid height difference can be effectively prevented; besides, the device is provided with an absorption air pressure control mechanism, the pressurevalue when the amniotic fluid is adsorbed can be effectively controlled, and therefore side effects caused when the amniotic fluid adsorption pressure is too large are effectively prevented.

Description

technical field [0001] The invention relates to the technical field of clutch mechanisms, in particular to a reflux-preventing special amniotic fluid aspirator for obstetrics and gynecology.
