Abstract
The utility model discloses a double-cavity type uterine cavity absorbing and scraping tube which comprises an absorbing and scraping tube body, an absorbing and scraping tube cavity and an absorbing and scraping mouth. The internally-attached tube wall of the absorbing and scraping tube cavity is provided with an air inlet tube cavity. An air outlet of the air inlet tube cavity is formed in the portion close to the head of an arc tube and the absorbing and scraping mouth. An air inlet is formed in the portion close to the tail of the arc tube and extends out of the tube wall of the absorbing and scraping tube. During an operation, when an absorbing and scraping head extends into the uterine cavity, an opening in the rear end of the air inlet tube cavity is pressed and plugged by the index finger, the opening is released after negative pressure is increased, air enters the uterine cavity under the effect of external atmosphere, and therefore uterine cavity tissues can be sucked out smoothly under the effect of the negative pressure. According to the double-cavity type uterine cavity absorbing and scraping tube, by the utilization of the air circulation principle, the uterine cavity tissues are sucked out smoothly under the low negative pressure, and therefore occurrence of complicating diseases is lowered.
Description
Technical field
This utility model relates to a kind of bicavate cavity of uterus sucking and scraping pipe.
Background technology
Traditional clearing heat in the pericardium sucking and scraping pipe is that a single lumen catheter is made, and this single lumen catheter is scraped in process in suction, and gas can not circulate, and in the time that negative pressure is on the low side, uterine cavity tissue is difficult to sucking-off.In the time attracting negative pressure too high, easily inhale and hinder myometrium again.Sometimes even cause that by fallopian tube tube chamber pelvic cavity negative pressure is too high, cause uterine cavity tissue suck-back to enter pelvic cavity and cause endometriosis, bring misery to patient.
Utility model content
This utility model object is to utilize the principle of gas circulation, and under less negative pressure, sucking-off uterine cavity tissue smoothly, reduces the generation of intercurrent disease.
The bicavate cavity of uterus sucking and scraping pipe that this utility model provides, comprise sucking and scraping pipe pipe shaft, sucking and scraping pipe tube chamber, inhale and scrape mouth, in sucking and scraping pipe tube chamber, paste tube wall and be provided with air inlet tube chamber, the gas outlet of air inlet tube chamber is located near arc tube head, approach suction and scrape mouth, air inlet is located near curved pipe tail and stretches out sucking and scraping pipe tube wall.
In art, suction is scraped to head and press stifled air inlet pipe cavity rear end opening with forefinger while stretching into uterine cavity, put its opening when increasing after negative pressure, gas enters uterine cavity under the atmospheric effect in the external world, and uterine cavity tissue smooth sucking-off under suction function.
