[0028] Embodiment 1

[0029] See also Figure 1-6 , the utility model provides the following technical solutions:

[0030] Specifically, it refers to an abdominal drainage catheter with an airbag, comprising a drainage catheter 1, wherein a metal hose 2 is sleeved inside the drainage catheter 1, an airbag component 3 is slidably matched on the peripheral side of the drainage catheter 1, and a fixing component 4 is slidably matched on the outer peripheral side of the drainage catheter 1 located on one side of the airbag component 3; the airbag component 3 comprises an airbag sleeve 301, a groove 302 is arranged on the outer peripheral side of the airbag sleeve 301, and a plurality of embedded grooves 303 are opened on the inner wall of the groove 302, and the airbag sleeve 301 is slidably matched with the drainage catheter 1; the fixing component 4 comprises a fixing sleeve 401, A plurality of hinged seats 402 are fixed to the outer peripheral side of the fixed sleeve 401, and a rotating plate 403 is hinged inside the hinged seat 402. A positioning plate 404 is fixed to one side of the rotating plate 403, an arc-shaped pressing tube 405 is fixed to the bottom of the rotating plate 403, and an embedding block 406 is fixed to the side of the arc-shaped pressing tube 405. A fastening nut 407 is threadedly connected to the outer peripheral side of the fixed sleeve 401, and a conical sleeve shell 408 is fixed to one side of the fixed sleeve 401. The arc-shaped pressing tube 405 is snap-fitted with the groove 302, and the embedding block 406 is snap-fitted with the embedding groove 303.

[0031] The specific application of this embodiment is: when the insertion depth of the drainage end of the drainage catheter 1 needs to be adjusted according to the depth of the peritoneal fluid in the patient's abdominal cavity, the relative positions of the airbag sleeve 301 and the fixed sleeve 401 on the drainage catheter 1 can be adjusted in turn according to the depth of the peritoneal fluid. After the position adjustment is completed, the fastening nut 407 threadedly connected to the outer peripheral side of the fixed sleeve 401 can be rotated. During the rotation of the fastening nut 407, the metal hose 2 sleeved on the inner wall of the drainage catheter 1 can provide certain support for the drainage catheter 1 to prevent the drainage catheter 1 from being flattened during the rotation of the fastening nut 407, which affects the subsequent drainage process. The rotation of the fastening nut 407 can make the conical sleeve 408 fixed on one side of the fastening nut 407 gradually approach one side of the plurality of hinged seats 402. During the process of approaching each other, The outer side surface of the conical sleeve 408 gradually contacts with the positioning plate 404 fixed on one side of the rotating plate 403, and at the same time provides a contraction force for the rotating plates 403 hingedly matched inside the hinge seat 402, thereby driving the rotating plates 403 to retract with each other until the arc-shaped pressure tube 405 and the clamping block 406 are successively engaged with the groove 302 and the clamping groove 303, and then the rotation of the fastening nut 407 is stopped, so as to position and fix the airbag sleeve 301 after the position adjustment, to prevent the airbag part 3 from loosening on the side of the drainage catheter 1 during the drainage process, to avoid the leakage of peritoneal effusion, and the position adjustment of the airbag sleeve 301 can be applicable to the drainage process of peritoneal effusion of different depths, to avoid the incomplete drainage of the patient's peritoneal effusion, thereby improving the applicability.

[0032] Embodiment 2

[0033] See also Figure 1-6 The second embodiment makes the following improvements on the basis of the first embodiment. Specifically, a plurality of rubber friction balls 409 are fixed to the inner wall of the fixed sleeve 401; an inflatable airbag 304 is fixed to the outer peripheral side of the airbag sleeve 301, and the outer peripheral side of the inflatable airbag 304 is connected to the air inlet pipe 305; a plurality of drainage holes 101 are opened on the side of the drainage catheter 1 near one end face; a limiting ring 201 is provided at one end of the metal hose 2, and one side of the limiting ring 201 is in contact with one end of the drainage catheter 1.

[0034] A specific application of this embodiment is: before drainage, the metal hose 2 can be slidably sleeved into the drainage catheter 1 until one side of the limiting ring 201 set at one end of the metal hose 2 fits with one end of the drainage catheter 1, so as to play a certain internal support effect on the position adjustment and fixing process of the airbag sleeve 301, and prevent the airbag sleeve 301 from being sunken in the drainage catheter 1 after the position adjustment, so as to avoid its influence on the subsequent drainage. After the position adjustment of the airbag sleeve 301 is completed, the metal hose 2 can be slid out from the drainage catheter 1, and then one end face of the drainage catheter 1 is connected and fixed to the drainage device. After the fixing is completed, the fixed sleeve 401 and the airbag sleeve 301 are slidably sleeved from the drainage end of the drainage catheter 1 to the surrounding side of the drainage catheter 1 in turn. When they slide to the desired position, the sliding sleeve connection process of the fixed sleeve 401 and the airbag sleeve 301 can be stopped. During the sliding sleeve connection process, if the inner wall of the fixed sleeve 401 is fixed The dry rubber friction ball 409 can increase the friction between the inner wall of the fixed sleeve 401 and the outer peripheral side of the drainage catheter 1 to prevent the fixed sleeve 401 from sliding after the position is determined. Then, the fixed sleeve 401 and the airbag sleeve 301 are fixed in sequence by slidingly fitting on the side of the drainage catheter 1. After the fixation is completed, the drainage end of the drainage catheter 1 can be inserted into the patient's abdominal cavity through the abdominal puncture port to ensure that the end of the drainage catheter 1 is located in the effusion area. Then, during the use process In the process, the air inlet end of the air inlet pipe 305 can be connected and fixed to the inflation device, and the inflation device can be controlled to start to inflate the inflatable airbag 304. During the inflation process, the inflatable airbag 304 is located on the abdominal wall and expands until the outer surface of the inflatable airbag 304 fits against the inner wall of the patient's abdominal cavity to form a sealed puncture port, effectively preventing the leakage of accumulated fluid from the abdominal puncture port, and finally starting the drainage device to discharge the abdominal accumulation in the patient's abdominal cavity through the drainage hole 101 and the drainage catheter 1.
