When the technical scheme is adopted, after the drainage tube is inserted into the abdominal cavity of a patient, the accumulated liquid flows out of the drainage tube, the accumulated liquid in the drainage tube flows into the inclined tube again, the accumulated liquid impacts the baffle, the torsion spring rotates to store force, the bottom tube opening of the inclined tube is opened by the baffle, the accumulated liquid flows into the communicating bag, and the accumulated liquid flows out of the communicating bag again to enter the drainage bag for collection. When the accumulated liquid does not flow out, the torsion spring is reset, and then the baffle is driven to seal the bottom pipe orifice of the inclined pipe. Therefore, when the drainage is carried out on the patient, the drained exudates can flow back to the abdominal cavity, and the abdominal cavity is prevented from being infected by bacteria.

Furthermore, the backflow prevention mechanism further comprises a stop valve, one end of the stop valve is fixedly installed on the inclined pipe, and the other end of the stop valve extends out of the communication bag.

Through the setting of stop valve, when the patient need not carry out the drainage, close the stop valve, and then avoid the hydrops to flow out, also place the hydrops that the drainage goes out simultaneously and flow back again in patient's abdominal cavity, avoid the patient by the risk of infection.

Further, be equipped with transfer line and medical rubber buffer in the intercommunication bag, the one end of transfer line with the top intercommunication of slope pipe, the other end of transfer line stretches out intercommunication bag and with outside intercommunication, medical rubber buffer seal install in keeping away from of transfer line in the mouth of pipe of the one end of slope pipe, the stop valve is located the baffle with between the transfer line.

Through the setting of transfer line and medical rubber stopper, close the stop valve earlier, pass medical rubber stopper with the syringe needle and carry normal saline to the transfer line in, normal saline enters into patient's abdominal cavity through the drainage tube, and then is convenient for wash patient's abdominal cavity.

Further, the drainage tube is sleeved with a flow regulator in a sliding mode, and the flow regulator can extrude the drainage tube.

Through setting up flow regulator, can adjust the speed of hydrops from patient's abdominal drainage better, avoid the speed of hydrops drainage too fast, cause the discomfort of health.

Further, the flow regulator comprises a sleeve, an arc-shaped plate and a threaded rod, the sleeve is sleeved on the drainage tube in a sliding mode, a threaded hole is formed in one side of the sleeve, the arc-shaped plate is located in the sleeve, and the threaded rod is installed in the threaded hole in a threaded rotating mode and is connected with the arc-shaped plate in a rotating mode.

Through rotating the threaded rod, and then adjust the degree that the arc extruded the drainage tube to adjust the speed of hydrops from patient's abdominal drainage.

Further, the bottom of the drainage bag is fixedly communicated with a liquid discharge pipe, and a liquid discharge switch is fixedly connected to the liquid discharge pipe.

And opening the liquid discharge switch, so that the accumulated liquid in the drainage bag can flow out of the body through the liquid discharge pipe.

The beneficial effect that this scheme produced is: through the setting of slope pipe, torsion spring and baffle, when the internal hydrops of patient was not discharged, torsion spring drove the bottom mouth of pipe that the slope pipe was sealed to the baffle. Thereby realize that the hydrops of drainage play can not flow back to in the abdominal cavity, avoid the abdominal cavity to be infected by the bacterium.

Detailed Description

The following is further detailed by way of specific embodiments:

as shown in fig. 1 to 3, an abdominal cavity drainage device comprises a drainage tube 1, a drainage bag 2, a communicating bag 3 and a backflow prevention mechanism 4.

Specifically, as shown in fig. 1 and 2, the middle part of the upper end of the communicating bag 3 is fixedly communicated with the drainage tube 1, and the middle part of the bottom end of the communicating bag 3 is fixedly communicated with the drainage bag 2.

Specifically, the backflow prevention mechanism 4 comprises an inclined pipe 41, a torsion spring 42, a baffle 43 and a stop valve 44, wherein the inclined pipe 41 is installed in the communicating bag 3 in a downward inclined mode, the top of the inclined pipe 41 is fixedly communicated with the drainage pipe 1, the torsion spring 42 is installed at the top of the bottom end pipe opening of the inclined pipe 41 in a rotating mode, the top of the baffle 43 is fixedly connected with the torsion spring 42, and the baffle 43 is in sealing abutting connection and sealing the pipe opening of the inclined pipe 41 in a natural state. Wherein, the bottom end of the stop valve 44 is fixedly arranged on the inclined pipe 41, and the top end of the stop valve 44 extends out of the communicating bag 3. Through the setting of stop valve 44, when the patient need not carry out the drainage, close stop valve 44, and then avoid the hydrops to flow out, also place the hydrops that the drainage goes out simultaneously and flow back again in patient's abdominal cavity, avoid the patient by the risk of infection.

Specifically, in order to clean the abdominal cavity of the patient, an infusion tube 5 and a medical rubber plug 6 are further arranged in the communication bag 3, and the stop valve 44 is positioned between the baffle 43 and the infusion tube 5. Wherein, the top of the transfusion tube 5 is communicated with the top of the inclined tube 41, the bottom end of the transfusion tube 5 extends out of the communicating bag 3 and is communicated with the outside, and the medical rubber plug 6 is hermetically arranged in the tube orifice at the bottom end of the transfusion tube 5. Through the setting of transfer line 5 and medical rubber stopper 6, close stop valve 44 earlier, pass medical rubber stopper 6 with the syringe needle and carry normal saline to transfer line 5 in, normal saline enters into patient's abdominal cavity through drainage tube 1, and then is convenient for wash patient's abdominal cavity.

In order to better regulate the drainage speed of effusion from the abdominal cavity of a patient, in the embodiment, the drainage tube 1 is slidably sleeved with the flow regulator 7, and the flow regulator 7 can press the drainage tube 1. Through setting up flow regulator 7, can adjust the speed of hydrops from patient's abdominal drainage better, avoid the speed of hydrops drainage too fast, cause the discomfort of health.

As shown in fig. 1 and 3, the flow regulator 7 includes a sleeve 71, an arc plate 72 and a threaded rod 73, the sleeve 71 is slidably sleeved on the drainage tube 1, a threaded hole is formed in the right side of the sleeve 71, the arc plate 72 is located in the sleeve 71, and the threaded rod 73 is rotatably installed in the threaded hole and rotatably connected with the arc plate 72.
