Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 4 As shown, the utility model provides a medical hepatobiliary drainage device, including a liquid storage tank 1, a vacuum pump 2 is arranged on the side of the liquid storage tank 1, a drainage pipe 3 is arranged at the bottom end of the liquid storage tank 1, the top of the liquid storage tank 1 is connected with a top connecting pipe 5, a drainage flow rate regulating mechanism 4 is also arranged above the liquid storage tank 1, the drainage flow rate regulating mechanism 4 is connected with the top connecting pipe 5, a closing valve 6 is also arranged on the top connecting pipe 5, and the drainage flow rate regulating mechanism 4 is connected with a drainage pipe 7.

[0025] In this embodiment, although the existing medical hepatobiliary drainage device can drain the liquid in the liver and gallbladder through the drainage catheter and the drainage bottle, the liquid flow rate during the drainage process cannot be controlled. When the flow rate of the drainage liquid is too fast, it is easy to cause pain to the patient, and in severe cases it may cause organ damage, which is very inconvenient for the patient to use.

[0026] By starting the vacuum pump 2, the vacuum pump 2 generates negative pressure to suck the drainage liquid, so that the top connecting tube 5 connected to the top of the liquid storage tank 1 sucks the drainage flow rate control mechanism 4, and the drainage flow rate control mechanism 4 extends into the patient's body through the drainage tube 7 set at its top to drain the liver and gallbladder, thereby extracting the liquid in the patient's body. By setting the drainage flow rate control mechanism 4 between the top connecting tube 5 and the drainage tube 7, the drainage flow rate control mechanism 4 can control the flow rate of the liquid entering therein, so that the device can conveniently adjust the flow rate while adapting to people of different ages and the amount of liquid to be extracted, so that the flow rate of the liver and gallbladder liquid can be controlled during the drainage process, avoiding the patient's pain caused by excessive flow rate, and at the same time will not cause damage to the patient's organs, which is more convenient for users to use.

[0027] like Figures 1 to 4 As shown, in the present embodiment, the drainage flow rate regulating mechanism 4 includes a top regulating chamber 401 arranged above the liquid storage tank 1, a first liquid storage ball tube 402 is arranged on the top side inside the top regulating chamber 401, a second liquid storage ball tube 403 is arranged below the first liquid storage ball tube 402, the top end of the first liquid storage ball tube 402 is connected to the drainage tube 7, the bottom end of the second liquid storage ball tube 403 is connected to the top connecting tube 5 passing through the bottom wall of the top regulating chamber 401, the second liquid storage ball tube 403 and the first liquid storage ball tube 402 are connected by a liquid inlet connecting tube 404, and a squeezing device is arranged on the liquid inlet connecting tube 404.

[0028] In this embodiment, by means of the second liquid storage bulb 403 and the first liquid storage bulb 402 arranged in the top regulating chamber 401, the second liquid storage bulb 403 can be connected with the top connecting tube 5, the first liquid storage bulb 402 can be connected with the drainage tube 7, and the first liquid storage bulb 402 and the second liquid storage bulb 403 are connected by means of the liquid inlet connecting tube 404. When the liquid passes through the inside of the liquid inlet connecting tube 404, the diameter can be adjusted by means of the squeezing device arranged on the side of the liquid inlet connecting tube 404, so that the flow rate of the body fluid flowing through the inside of the liquid inlet connecting tube 404 can be adjusted to a certain extent, so that the drainage flow rate can be controlled.

[0029] like Figures 1 to 4As shown, in this embodiment, the extrusion device includes a fixed connecting seat 405 arranged in the middle of the side of the top adjusting bin 401, the end of the fixed connecting seat 405 extends into the top adjusting bin 401, and a limiting through hole 406 is provided at the end of the fixed connecting seat 405. The liquid inlet connecting pipe 404 passes through the limiting through hole 406, and a sliding inner cavity 407 is arranged on the inner wall of the limiting through hole 406. A regulating screw 408 is threadedly inserted in the sliding inner cavity 407, and the end of the regulating screw 408 passes through the inner wall of the sliding inner cavity 407 and extends to the outside of the fixed connecting seat 405. A pushing slide 409 is rotatably arranged at the end of the regulating screw 408, and a resistance ball 410 is arranged in the sliding inner cavity 407. A resistance spring 411 is arranged on the side of the resistance ball 410, and the end of the resistance spring 411 is connected to the pushing slide 409.

[0030] When the user needs to lower the drainage flow rate, the user turns the regulating screw 408 set on the top regulating bin 401, so that the regulating screw 408 pushes the push slide 409 to slide inside the sliding inner cavity 407, thereby driving the resistance spring 411 to push the resistance ball 410, so that the resistance ball 410 can resist the wall of the liquid inlet connecting tube 404 passing through the limiting through hole 406, so that the internal diameter of the liquid inlet connecting tube 404 is gradually reduced, thereby achieving the purpose of reducing the liquid flow rate inside the liquid inlet connecting tube 404, making it convenient for people to use.

[0031] The side of the top regulating chamber 401 is stably connected to the top of the liquid storage tank 1 through a fixed frame.

[0032] The end of the regulating screw 408 is provided with anti-slip grooves for increasing friction.
