Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0020] Example. A peritoneal puncture and drainage device with anti-leakage fluid, such as... Figure 1 As shown, the device includes a silicone drainage tube 1, with a drainage channel 2 formed on the inner side of the drainage tube 1. Multiple drainage holes 18 are provided on the side wall of the front end of the drainage tube 1. A second guide head 20 is provided at the front end of the drainage tube 1, and the front end of the second guide head 20 is spherical. The second guide head 20 facilitates smooth puncture while avoiding secondary abrasions to the patient during the puncture process.
[0021] The outer side of the drainage tube 1 is provided with a silicone sleeve 3. The front end of the sleeve 3 is contracted inward and fixed to the drainage tube 1, so that the front end of the sleeve 3 is closed, and a water injection channel 4 extending backward is formed between the sleeve 3 and the drainage tube 1.
[0022] The front part of the sheath 3 is provided with an annular groove 9. By setting the annular groove 9, the wall thickness of the sheath 3 at this point is reduced, forming a deformable bladder 19. The bladder 19 can expand into a spherical shape under a certain water pressure, which is the same principle as the inflation of a balloon.
[0023] The rear end of the drainage tube 1 is equipped with a connector 5, such as... Figure 2 As shown, connector 5 includes a head 11. The rear end of the sheath 3 and the rear end of the drainage tube 1 are both fixed to the front end of the head 11. The rear end of the head 11 is provided with a drainage interface 6, which is connected to the rear end of the drainage channel 2. A branch pipe 12 is provided on the side wall of the head 11, forming an angle of less than 30° between the head 11 and the branch pipe 12. The rear end of the branch pipe 12 is provided with a water injection interface 7, which is connected to the rear end of the water injection channel 4. An annular cavity 10 is provided on the front end face of the head 11, located between the sheath 3 and the drainage tube 1, and connected to the branch pipe 12.
[0024] The water injection interface 7 is provided with a one-way valve 8 between the water injection channel 4. The one-way valve 8 is formed by a part of the branch pipe 12 expanding radially outward to form a valve cavity 13, which is cylindrical. The valve cavity 13 is provided with a valve core, which includes a bottom plate 14 provided with a first guide head 15 inserted into the water injection joint 5. The bottom plate 14 is provided with a helical compression spring 16 on one side. The outer periphery of the bottom plate 14 and the outer periphery of the first guide head 15 are both provided with a plurality of water channels 17. Under the action of the compression spring 16, the bottom plate 14 is tightly attached to the bottom surface of the rear side of the valve cavity 13, so that the water injection interface 7 is disconnected from the water injection channel 4. When the water injection interface 7 is connected to water with a certain pressure, the valve core moves forward under the water pressure, and the one-way valve 8 is opened.
[0025] The drainage interface 6 is connected to a drainage device to suction the abdominal cavity effusion. When not suctioning, the drainage interface 6 is closed by a plug. Preferably, a one-way valve can also be provided on the drainage interface 6.
[0026] Method of use: The front end of the drainage device is inserted into the abdominal cavity through the drainage port, and at this time the capsule sleeve 19 is located in the abdominal cavity. A syringe is used to suck physiological saline, and the front end of the syringe is tightly fitted into the water injection interface 7 to establish a sealed connection therebetween. Physiological saline is pressurized by pushing the plunger of the syringe, so that the one-way valve 8 is opened, and the physiological saline enters the water injection channel. Under the action of the pressure, the capsule sleeve 19 expands into a spherical shape. The syringe is pulled out, and under the action of the compression spring 16, the one-way valve 8 is closed, so that the physiological saline cannot leak out. The drainage tube 1 exposed to the outside of the skin is pulled tight, so that the spherical capsule sleeve 19 adheres to the inner wall of the abdominal cavity to block the drainage port. A small-sized dressing is used to preliminarily fix the drainage tube 1 to the abdominal wall skin, and a large-sized dressing is used for secondary fixation.
