It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0026] In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. In the description of the present utility model, the meaning of "a plurality" is more than two, unless otherwise clearly and specifically defined.

[0027] As Figures 1-4 shown, the present utility model provides an anti - detachment catheter for pediatric urological care, including a first catheter body 10, a second catheter body 20, a sleeve 30, an airbag 40, an annular lifting tube 50 and a driving assembly 60.

[0028] A connecting tube 70 is arranged between the first catheter body 10 and the second catheter body 20. The first end of the connecting tube 70 is fixedly connected to the first end of the first catheter body 10 and keeps sealed. The second end of the connecting tube 70 is fixedly connected to the first end of the second catheter body 20 and keeps sealed. The two ends of the connecting tube 70 are respectively in communication with the first end of the first catheter body 10 and the first end of the second catheter body 20.

[0029] The sleeve 30 is sleeved outside the first catheter body 10. An annular cavity 32 is formed between the sleeve 30 and the first catheter body 10. The first end of the sleeve 30 is fixedly connected to the first catheter body 10 and keeps sealed. An annular socket 31 is formed between the second end of the sleeve 30 and the first catheter body 10. The annular socket 31 is in communication with the annular cavity 32. A notch 33 communicating with the annular cavity 32 is opened on the outer side surface of the first end of the sleeve 30.

[0030] The airbag 40 is fixedly installed on the outer side surface of the sleeve 30 and remains sealed, and the airbag 40 communicates with the notch 33.

[0031] The annular lifting pipe 50 is arranged in the annular socket 31, and the annular lifting pipe 50 is in sliding contact with the inner wall of the annular socket 31 and remains sealed.

[0032] The driving assembly 60 is used to control the up and down movement of the annular lifting pipe 50 in the annular socket 31.

[0033] In the initial state, the airbag 40 is in a contracted state and hidden in the notch 33.

[0034] The specific use process is as follows: First, the medical staff inserts the second end of the first urinary catheter body 10 into the bladder of the child patient through the urethra. Then the medical staff controls the annular lifting pipe 50 to move upward in the annular socket 31, and the compressed gas in the annular cavity 32 will enter the airbag 40 through the notch 33 to inflate the airbag 40. The airbag 40 expands outward to fix the second end of the first urinary catheter body 10 in the bladder, preventing the second end of the first urinary catheter body 10 from falling off from the bladder. This fixing method has better firmness and reduces the discomfort of the child patient. The urine in the bladder is discharged outward through the first urinary catheter body 10, the connecting pipe 70 and the second urinary catheter body 20.

[0035] When it is necessary to remove the second end of the first urinary catheter body 10 from the bladder, the medical staff only needs to control the annular lifting pipe 50 to move downward in the annular socket 31. The gas in the airbag 40 will enter the annular cavity 32 through the notch 33, the airbag 40 contracts and hides in the notch 33, and then the first urinary catheter body 10 can be pulled out outward.

[0036] In one embodiment, the outer peripheral surface of the connecting pipe 70 has an external thread. The driving assembly 60 includes a rotating ring 61. The rotating ring 61 is sleeved on the connecting pipe 70, and the inner wall of the rotating ring 61 has an internal thread. The rotating ring 61 is in threaded cooperation with the connecting pipe 70. An annular guiding groove 62 is formed on the end surface of the rotating ring 61, and an annular guiding block 51 is fixedly installed on the outer end surface of the annular lifting pipe 50. The annular guiding block 51 is in sliding contact with the annular guiding groove 62, and the axis line of the rotating ring 61 coincides with the axis line of the lifting pipe 50.

[0037] When the medical staff controls the rotating ring 61 to rotate forward, since the rotating ring 61 is in threaded cooperation with the connecting pipe 70, the annular lifting pipe 50 will move upward. On the contrary, when the medical staff controls the rotating ring 61 to rotate reversely, the annular lifting pipe 50 will move downward. Therefore, the medical staff can control the up and down movement of the annular lifting pipe 50 by controlling the rotation of the rotating ring 61, and the operation is convenient.

[0038] In one embodiment, the connecting pipe 70 is made of a rigid metal material, so that the connecting pipe 70 has better rigidity and is not easily bent, which further facilitates the medical staff to control the rotation of the rotating ring 61. Preferably, the rigid metal material is steel or aluminum alloy or titanium alloy.

[0039] In one embodiment, the rotating ring 61 has anti-slip lines to prevent the medical staff from slipping when controlling the rotation of the rotating ring 61.

[0040] In one embodiment, an annular sealing groove is formed on the inner wall of the annular socket 31, and an annular sealing ring 34 is fixedly installed in the annular sealing groove. The annular sealing ring 34 is in close contact with the annular lifting pipe 50, enhancing the sealing performance between the annular lifting pipe 50 and the annular socket 31 and preventing the gas in the annular cavity 32 from leaking.

[0041] In one embodiment, a guide rod 35 is fixedly installed on the inner wall of the annular socket 31, and the guide rod 35 is slidably connected to the annular lifting pipe 50. Under the action of the guide rod 35, when the medical staff controls the rotation of the rotating ring 61, the annular lifting pipe 50 will move up and down stably without being driven to rotate by the rotating ring 61, making the present utility model more stable in use.

[0042] In one embodiment, both the airbag 40 and the notch 33 are annular structures.

[0043] The above shows and describes the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present utility model.
