Drainage device for obstetric operation

Abstract

The invention relates to a drainage device for an obstetric operation. The drainage device for the obstetric operation comprises a collection cavity and a sealing cover detachably connected with the collection cavity, the sealing cover is provided with two connectors, and the two connectors are respectively communicated with a negative pressure assembly and an insertion tube; a puncture needle isarranged on the inner side of the end, away from the connector, of the insertion tube; the puncture needle is connected with a driving assembly installed on the insertion tube, and the driving assembly drives the puncture needle to protrude out of the end of the insertion tube and retract into the insertion tube after puncture is completed; the other end of the connector communicated with the insertion tube penetrates through the sealing cover and is connected with a U-shaped pipe; and a plug assembly is arranged in the U-shaped pipe. The driving assembly drives the puncture needle to protrudeout of the insertion tube to conduct the puncture work, the puncture needle is retracted into the insertion tube after puncture is completed, it can be effectively avoided that in the drainage process, the protruding puncture needle causes secondary injury to a patient, and safety performance is high.

Description

technical field [0001] The invention relates to the related technical field of medical devices, in particular to a drainage device for obstetric surgery. Background technique [0002] At present, in obstetrics and gynecology surgery, drainage bags are often used for negative pressure drainage of wounds. Existing drainage devices generally use drainage bottles, drainage tubes and puncture needles. The effusion is drained under its own pressure, and the effusion cannot be completely drained. If it is completely withdrawn, effusion backflow will occur; therefore, another drainage device will be installed with a negative pressure device, and the drainage bag will use the external negative pressure drainage device to generate negative pressure to drain the liquid into the drainage bag. The fluid in the patient's body is drawn out. [0003] The current negative pressure drainage device is composed of a drainage tube and a drainage bag. It has a good negative pressure suction and ...

Problems solved by technology

[0002] At present, in obstetrics and gynecology surgery, drainage bags are often used for negative pressure drainage of the wound. The existing drainage devices generally use drainage bottles, drainage tubes and puncture needles. The effusion is drained under its own pressure, and the effusion cannot be completely drained. If it is completely drawn out, the effusion backflow phenomenon will occur; therefore, another drainage device will be installed with a negative pressure device, and the drainage bag will use the external negative pressure drainage device to generate negative pressure, so that the liquid can be drained into the drainage bag. Aspirate fluid from the patient

[0003] The current negative pressure drainage device is composed of a drainage tube and a drainage bag. It has a good negative pressure suction and can avoid reflux infection. However, due to the existence of the puncture needle, the puncture needle is always exposed during the drainage process, which is easy for pregnant women. Cause secondary damage, low safety performance
