Description

Cervical drainage device and drainage system

technical field

The utility model relates to the technical field of medical devices, in particular to a cervical drainage device and a drainage system.

Background technique

Obstetric blood loss is the leading cause of maternal death. Bleeding from the uterine cavity can quickly flow into the vagina through the cervical canal, and coagulate and collect under the buttocks through the vagina. The traditional clinical methods of counting transcervical blood loss are visual assessment and measurement by weighing after surgery. However, this method has great limitations: due to the hidden location of blood loss and the rapid coagulation of blood flowing through the cervix, the accuracy of the estimation is seriously affected, and even a large amount of blood may directly coagulate and accumulate in the vagina, resulting in the measurement of blood loss. mistake. In short, the currently commonly used measurement methods can neither detect the blood loss through the cervical canal in time nor accurately measure it.

Chinese patent document CN201721527159.4 discloses a disposable cervical drainage hood, which helps the inner surface of the drainage tube to cover the external opening of the cervix through an inflatable hood, and plays the role of fixing the drainage tube, which is conducive to "full drainage or suction through the cervix." "lost blood", but the device does not have anticoagulant effect, once the blood coagulates, it will not be able to effectively drain the blood.

In addition, none of the cervical drainage tubes disclosed in Chinese patent documents CN201621037193.9, CN201621037192.4 and CN200420008457.9 can also solve the problem that the drainage liquid coagulates and blocks the catheter. Blockage of the catheter by fluid coagulation will result in less fluid collected than the actual fluid volume, making it difficult to accurately measure the amount of bleeding in real time.

To sum up, there is currently a lack of a device for collecting transcervical drainage fluid that is convenient for real-time and accurate measurement.
