During cesarean section, a negative pressure suction device is needed to suck out amniotic fluid and blood in the uterus, the pelvic cavity or the abdominal cavity. The suction device adopted by the applicant at present comprises a suction apparatus and a suction bag, wherein the suction bag comprises a suction bag cover and a bag body, a suction joint and a negative pressure joint are connected to the suction bag cover, and the suction joint and the negative pressure joint are both communicated with the bag body. The suction bag is put into the suction apparatus, the suction bag cover is matched and sealed with the suction apparatus, the negative pressure joint and the suction apparatus are connected with negative pressure, and the suction joint is connected with the suction pipe. The negative pressure suction reduces the air pressure between the bag body and the suction apparatus and also reduces the air pressure in the bag body; the bag body is communicated with the suction joint to suck air or liquid, and the bag body is sealed with the suction device, so that the air pressure between the bag body and the suction device is lower, and the bag body is expanded. The suction tube is inserted into uterus, and amniotic fluid and blood in uterus can be sucked into the bag body under the action of negative pressure. The suction bag of the suction device is disposable, the suction device is reusable, the bag body of the suction bag is a soft plastic bag, the suction bag is low in cost and convenient to store, and the suction bag has advantages compared with other negative pressure suction devices.

When the negative pressure suction is performed during the cesarean section, the amniotic fluid and the blood are preferably sucked out respectively, so that the amniotic fluid and the blood are respectively measured. The accurate measurement of the amniotic fluid volume and the blood volume has important clinical significance. The negative pressure suction device can not separate the sucked amniotic fluid from the sucked blood, is not beneficial to respectively measuring the amniotic fluid volume and the blood volume, and needs two suction devices to respectively suck the amniotic fluid and the blood and is inconvenient in clinical operation if the amniotic fluid and the blood are separately sucked and measured.

ZL200820233544.2 discloses a cesarean section hydroblood shunt aspirator, and the aspirator includes three metering bottles, can inhale amniotic fluid and blood in different metering bottles through adjusting the tee bend. The suction apparatus has the following disadvantages: 1. the number of the metering bottles is large, and the use is inconvenient; the price of the measuring bottle is higher than that of the suction bag, and the hard volume can not be reduced, so that the measuring bottle is inconvenient to store; 2. when negative pressure suction is carried out during cesarean section, a suction tube extending into the uterus needs to be held by hands; when the common tee joint is adjusted, the common tee joint needs to be operated by two hands, namely, the tee joint is held by one hand, and a knob of the tee joint is rotated by the other hand; this makes the switching operation inconvenient for a single person.
