Background
The artificial abortion is a remedial measure after contraceptive failure and mainly comprises the traditional negative pressure uterine aspiration and drug abortion technologies and the like. The devices needed by the negative pressure uterine aspiration are divided into an electric negative pressure aspirator and a traditional manual negative pressure aspirator; in practical application, the aspirator used in the induced abortion operation needs to be connected with the aspiration tube to extend into the uterus, directly contact with the group fabric on the endometrium, and aspirate embryo tissues out of the uterus through negative pressure aspiration operation, thereby achieving the purpose of stopping pregnancy.
The problems of the prior art are: the cylinder body of the traditional negative pressure aspirator lacks negative pressure scale marks, the negative pressure accuracy is poor, accurate negative pressure absorption control is difficult to realize, and medical staff can judge the negative pressure in the current operation only through experience; meanwhile, when the method is specifically operated, the method can only implement the suction of the roller according to the maximum negative pressure each time, and the selection and adjustment of different negative pressures can not be realized.
Because the embryo tissue of the human body has great difference in size after 5-6 weeks of growth compared with 8-10 weeks of growth, the required maximum suction negative pressure requirement is completely different because of different suction volumes; in addition, in different stages of negative pressure uterine aspiration, the requirements on negative pressure are different, if the traditional negative pressure aspirator is adopted, the adaptability adjustment capability is poor, and specific negative pressure aspiration operation can not be implemented on patients with different gestation periods and in different stages of operation, so that the traditional negative pressure aspirator often excessively aspirates the uterine endometrium to cause damage or causes incomplete abortion. In addition, the maximum suction negative pressure of the cylinder of the traditional negative pressure dynasty is about 375mmhg, which can only be applied to patients with 5-7 weeks of accidental pregnancy, the device can not be suitable for 8-10 weeks of accidental gestation patients, because the maximum suction negative pressure still can not meet the related technical requirements.
The traditional negative pressure aspirator adopts a valve design that the inclined plane is limited and blocked, the traditional valve design has poor locking stability and reliability of the valve, and is easy to fall off, so that the valve is unstable in locking the negative pressure; simultaneously, medical staff easily carelessly touch the valve and cause the inclined plane card to be unable, and the valve kick-backs this moment, becomes malleation by negative pressure in the twinkling of an eye, and just the hydrops that absorbs will be taken back in the uterus together with the air fast, causes the injury to blood vessel, endometrium etc. on the endometrium, and serious condition can lead to the air embolism, endangers patient life safety.
