Described attraction import, decompression import, negative pressure control gas outlet are distributed in the front portion of body, and said attraction outlet, relief outlet and negative pressure control air inlet are distributed in body and are in the part in the handle;
Said handle has the main interface that is connected with attraction equipment, and attracts import that the attraction outlet in chamber joins and the circulation road between them; Said handle also has unidirectional outlet and unidirectional import; Said unidirectional import communicates with the negative pressure control air inlet of negative pressure control chamber, and breather cheek valve wherein is housed, and the relief outlet of said unidirectional outlet and relief chamber communicates, and unidirectional air outlet valve wherein is housed.
On the basis of adopting technique scheme, this utility model also can adopt following further technical scheme:
In the said unidirectional import dustproof filter layer is housed.
On the body cross section, said negative pressure control chamber and relief chamber are in a side, and said attraction chamber is in opposite side.
The opening direction of said decompression import and negative pressure control gas outlet is towards negative pressure control chamber and residing this side of relief chamber, and the opening direction of said attraction import is towards attracting residing this side in chamber.
This utility model also can be provided with visual guider, and said visual guider is in said suction catheter body head, and said decompression import and negative pressure control gas outlet are in the rear of visual guider.
Said visual guider comprises pin type photographic head and light source.
Owing to adopt above technical scheme; Be with the existing miscarriage pipet main distinction: this utility model in use; In case when occurring systolic pressure or negative pressure in the uterine cavity; Pressure reduction can in time be adjusted through relief chamber and negative pressure control chamber, can prevent artificial abortion's art Middle Palace blood adverse current, prevention endometriosis and infertility; Reduce Uterus wall muscular tension in artificial abortion's art, reduce hemorrhagely, ease the pain; Simultaneously relief chamber and negative pressure control chamber are unidirectional one to go out one and advance, and the crimson blood discharge can not reflux, and avoids cross infection; The air inlet adjust blood pressure can prevent that through filter course air unclean in the operating room from directly getting into uterine cavity; Thereby lower uterine cavity and infect probability; And the outfit of visual guider; More increase intuitive and the accuracy rate (directly subtend embryonal tissue) in the operation, also do not influenced the operate as normal in three chambeies simultaneously; Thereby the shortest available treatment time, the most accurate target treatment means obtain best therapeutic modality (Wicresoft, wound is minimum).Reach best therapeutic effect.
