Description

Negative pressure suction bottle for gynecology

Technical Field

The utility model relates to the field of medical equipment, in particular to a negative pressure suction bottle for gynecology.

Background

When gynecological operations such as doctor's, abortion, uterine curettage, etc. are carried out, a negative pressure suction device is generally used to suck endometrium or gestational tissue. The tissue aspirated from the uterine cavity is typically a mixture of tissue, blood, mucus. Usually, after the operation is finished, a strainer and a filter gauze are needed to wash and filter out the uterine cavity tissue, and then clinical diagnosis and pathological examination are carried out. The filtering and cleaning steps of the uterine cavity tissues not only reduce the working efficiency, but also easily cause the uterine cavity tissues to be washed and lost by water in the filtering and cleaning process, such as the villus tissue of pregnancy or the only small amount of endometrium to be lost, and cause great psychological burden to patients and surgeons. And the complex operation filtering and flushing process has the potential risk of cross infection and tissue specimen confusion.
