[0068] The server provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0069] Example 1:

[0070] like Figure 1-6As shown, this application embodiment provides a traction device 1 for compressing a urinary catheter for hemostasis, including a traction device 1 for pulling the urinary catheter A5. The traction device 1 is composed of an adjustment unit 101, a protection unit 102, and a fixing unit 103 connected in sequence, and the urinary catheter A5 is sequentially inserted between the adjustment unit 101, the protection unit 102, and the fixing unit 103. The adjustment unit 101 is used to adjust the clamping strength of the urinary catheter A5 that is adapted to it. The front end of the protection unit 102 is connected to the adjustment unit 101 and is used to place the penis A4. The fixing unit 103 is detachably installed at the rear end of the protection unit 102 and is worn in the pubic area of ​​the lower abdomen.

[0071] Furthermore, the adjustment unit 101 includes an elastic adjustment component 2 connected to the front end of the protection unit 102; and a catheter fixing component 3, which is adjustablely mounted on the elastic adjustment component 2.

[0072] Furthermore, the catheter fixation assembly 3 includes an installation sleeve 301, which is movably mounted on the elastic adjustment assembly 2; a fixing sleeve 302, which is fixedly connected to the front end of the installation sleeve 301; an external thread 303 on the fixing sleeve, which is disposed on the outer wall of the fixing sleeve 302; a fixing nut 304, which is threadedly mounted on the fixing sleeve 302; and several openings 305, which are respectively axially disposed on the outer wall of the fixing sleeve 302.

[0073] Furthermore, it also includes an internal thread 4 on the mounting sleeve, which is provided on the inner wall of the mounting sleeve 301; and a first clearance hole 5, which is provided on the bottom surface of the inner cavity of the mounting sleeve 301 and extends to the outside of the mounting sleeve 301.

[0074] Furthermore, the elastic adjustment component 2 includes an adjustment sleeve 201, which is movably installed inside the mounting sleeve 301; an external thread 202 on the adjustment sleeve, which is disposed on the outer wall of the adjustment sleeve 201 and cooperates with the internal thread 4 of the mounting sleeve; an elastic element 203, which is movably installed inside the adjustment sleeve 201; and a second clearance hole 204, which is disposed on the bottom surface of the inner cavity of the adjustment sleeve 201 and extends through to the outside of the adjustment sleeve 201.

[0075] In this embodiment of the application, due to the aforementioned structure, patients with prostate cancer, hypertrophy, etc., who require prostatectomy, may experience bleeding at the bladder neck A1. Currently, a dilating balloon on the catheter A5 is often used to compress and stop the bleeding at the bladder neck A1. When fixing the catheter A5, nurses often use gauze for fixation. However, gauze cannot effectively control and maintain the clamping stability of the catheter A5, resulting in the catheter A5 becoming too tight or too loose. Therefore, a device that facilitates the control of the catheter A5 is needed. The catheter A5 is installed on the traction device 1, and the position of the catheter A5 is changed by the adjustment unit 101, and the clamping strength of the catheter A5 is adjusted. The urinary catheter A5 is inserted into the inner hole of the fixing sleeve 302, passing through the first clearance hole 5, the second clearance hole 204, and the guide groove 9 in sequence, and then into the penis A4. After the urinary catheter A5 is inserted, the fixing nut 304 is first screwed inward. During the screwing process, the fixing nut 304 compresses the external thread 303 of the fixing sleeve. At this time, the gap between the four openings 305 on the fixing sleeve 302 becomes smaller. When the fixing sleeve 302 locks the urinary catheter A5 and prevents it from slipping, the screwing of the fixing nut 304 can be stopped. Soft materials (such as soft rubber, silicone, etc.) can be placed in the inner wall of the fixing sleeve 302. Due to the different thicknesses of the urinary catheters A5, to avoid damage to the outer wall of the urinary catheter A5 during the locking process, the openings 305 and the fixing nut 304 facilitate the fixing sleeve 302 to fix urinary catheters A5 of various diameters.

[0076] Furthermore, by adjusting the distance between the elastic adjustment component 2 and the catheter fixing component 3, the catheter A5 is pulled to move. When the catheter A5 needs to be pulled, the adjusting sleeve 201 is rotated inward, the elastic element 203 deforms, the elastic element 203 is a spring, the spring shortens, and the adjusting sleeve 201 moves towards the rocker 7. Since the external thread 202 of the adjusting sleeve and the internal thread 4 of the mounting sleeve are matched, the adjusting sleeve 201 and the mounting sleeve 301 are connected by threads. When the adjusting sleeve 201 moves towards the rocker 7, the mounting sleeve 301 receives a reaction force and moves in the opposite direction of the adjusting sleeve 201. The mounting sleeve 301 drives the fixing sleeve 302 that clamps the catheter A5 to move outward together, so that the catheter A5 receives traction force, so that the catheter A5 moves and drives the dilating balloon to reach the bladder neck A1. The dilating balloon on the catheter A5 compresses the bleeding site of the bladder neck A1 to stop the bleeding. The threaded design allows nurses to easily adjust the position between the installation sleeve 301 and the adjustment sleeve 201, thereby adjusting the position of the urinary catheter A5. During the adjustment process, the urinary catheter A5 is always locked by the fixing sleeve 302, thus ensuring the stability of the urinary catheter A5 when pulled.

[0077] Example 2:

[0078] like Figure 4-9As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a protective unit 102 comprising a protective sheet 6, the two ends of which are respectively connected between the elastic member 203 and the fixing unit 103; a rocker plate 7, which is fixedly connected to the front end of the protective sheet 6 for protecting the glans; an elastic member guide post 8, which is disposed on the outer end face of the rocker plate 7; and a guide groove 9, which is disposed on the elastic member guide post 8 and extends to the inner wall of the rocker plate 7; wherein the elastic member 203 is sleeved on the elastic member guide post 8.

[0079] Furthermore, it also includes an extension piece 10, which is adjustablely installed at the rear end of the protective piece 6 to extend the overall length of the protective piece 6; a protrusion 11, which is disposed at the bottom end of the extension piece 10; and a threaded post 12, which is fixedly connected to the lower end face of the protrusion 11.

[0080] Furthermore, it also includes a slide groove 13, which is disposed on the protective plate 6 and has a protrusion 11 slidably installed inside; an annular groove 14, which is disposed on the slide groove 13 and has a threaded post 12 inserted inside; and an adjusting nut 15, which is adjusted and installed on the threaded post 12.

[0081] In this embodiment of the application, due to the aforementioned structure, the adjustment unit 101 is mounted on the protection unit 102. The protection unit 102 protects the penis A4, and the penis A4, placed on the protective plate 6, also provides support. Since the length of the penis A4 varies among different men, the overall length of the protective plate 6 needs to be adjustable. An adjustable extension plate 10 is added to the rear end of the protective plate 6 near the fixing unit 103. When adjusting the overall length of the protective plate 6, the adjusting nut 15 is first loosened. The adjusting nut 15 moves downward along the threaded post 12. At this time, the upper end face of the adjusting nut 15 is not in contact with the lower bottom face of the protective plate 6, and the locking force between the protective plate 6 and the extension plate 10 is lost. When the protective plate 6 is pulled outward, the overall length of the protective plate 6 and the extension plate 10 is increased; when the protective plate 6 is pushed inward, the overall length of the protective plate 6 and the extension plate 10 is shortened. During the movement of the protective plate 6, the protrusion 11 moves along the slide groove 13, and the threaded post 12 moves within the annular groove 14. When the length is adjusted to a suitable position, the adjusting nut 15 is tightened upward. A dressing with absorbent and anti-inflammatory effects can be placed inside the rocker arm 7 of the protective plate 6 to protect and reduce inflammation of the glans penis.

[0082] Example 3:

[0083] like Figure 4-6 , Figure 9-11As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a pair of connecting pieces 16, which are respectively fixedly connected to the rear ends of the extension piece 10 on both sides; a pair of mounting posts 17, which are respectively fixedly connected to each connecting piece 16; a pair of mounting grooves 18, which are respectively disposed on each mounting post 17; and a pair of positioning holes 19, which are respectively disposed on the inner wall of each mounting groove 18 and communicate with the outside of the mounting post 17.

[0084] Furthermore, the fixing unit 103 includes a support plate 20, which fits against the pubic area of ​​the lower abdomen of the human body; a pair of connecting posts 21, which are respectively disposed on the support plate 20 and installed in each mounting groove 18, and located at the corresponding metatarsal symphysis of the support plate 20; a pair of movable grooves 22, which are respectively disposed on each connecting post 21; a pair of compression springs 23, which are respectively installed in each movable groove 22; and a pair of locking beads 24, which are respectively movably installed in each movable groove 22, with half of them protruding outside the movable groove 22; wherein, the two ends of the pair of compression springs 23 are fixedly connected between the bottom end of the movable groove 22 and the locking beads 24.

[0085] In this embodiment of the application, due to the above-described structure, the combined adjustment unit 101 and protection unit 102 are detachably mounted on the fixing unit 103. The support plate 20 is attached to the pubic area of ​​the lower abdomen of the human body. The lower ends of the support plate 20 are located at the pubic symphysis. A pair of connecting posts 21 are provided on the support plate 20. The pair of connecting posts 21 are respectively located at the pubic symphysis corresponding to the support plate 20. Mounting posts 17 are respectively provided on both sides of the connecting piece 16 of the extension piece 10. Each connecting post 21 is installed in the mounting groove 18 of each mounting post 17. During installation, hold each mounting post 17 with both hands and align the mounting groove 18 of each mounting post 17 with each connecting post 21. As the connecting post 21 is inserted into the mounting groove 18, the side wall of the mounting groove 18 presses against the locking ball 24, causing the locking ball 24 to move along the movable groove 22. At this time, the compression spring 23 shortens. When the connecting post 21 is inserted into the movable groove 22 and corresponds to the positioning hole 19, the locking ball 24 is released from compression. The compression spring 23 returns to its original position and pushes the locking ball 24 outward along the movable groove 22. The locking ball 24 moves outward and one-third of its length moves into the positioning hole 19. The locking ball 24 positions the mounting post 17 and ensures the connection between the connecting post 21 and the mounting post 17. During disassembly, each mounting post 17 is held by both hands and pulled outward. During the pulling process, the inner wall of the mounting groove 18 compresses the locking bead 24, causing the locking bead 24 to move into the movable groove 22. The locking bead 24 disengages from the positioning hole 19, and the connection between the mounting post 17 and the connecting post 21 is lost. The mounting post 17 can then be directly removed from the connecting post 21. The locking bead 24, compression spring 23, and positioning hole 19 facilitate nurses in removing the adjustment unit 101 and protection unit 102 from the wearable device, and also facilitate patient wear.
