In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0068] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0069] Embodiment 1:

[0070] like Figure 1-6 As shown, an embodiment of the present application provides a traction device 1 for compressing a hemostatic catheter, including a traction device 1 for pulling a 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 catheter A5 is sequentially inserted between the adjustment unit 101, the protection unit 102 and the fixing unit 103; wherein the adjustment unit 101 is used to adjust the clamping strength of the catheter A5 adapted thereto; the protection unit 102, whose front end is connected to the adjustment unit 101, is used to place the penis A4; the fixing unit 103, which is detachably mounted on the rear end of the protection unit 102, and is worn in the pubic area of ​​the lower abdomen of the human body.

[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 adjustably mounted on the elastic adjustment component 2 .

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

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

[0074] Furthermore, the elastic adjustment component 2 includes an adjustment sleeve 201, which is movably installed in the mounting sleeve 301; an adjustment sleeve external thread 202, which is arranged on the outer wall of the adjustment sleeve 201 and cooperates with the mounting sleeve internal thread 4; an elastic member 203, which is movably installed in the adjustment sleeve 201; and a second air avoidance hole 204, which is arranged on the bottom surface of the inner cavity of the adjustment sleeve 201 and penetrates to the outside of the adjustment sleeve 201.

[0075] In this embodiment of the present application, due to the use of the above structure, patients with prostate cancer, hypertrophy, etc. need to undergo prostatectomy, which will cause bleeding in the bladder neck A1. Now, the expansion balloon on the catheter A5 is mostly used to compress the bladder neck A1 to stop bleeding. When fixing the catheter A5, nurses mostly use gauze to fix it, but the gauze cannot better control and maintain the clamping stability of the catheter A5. The catheter A5 may be too tight or too loose, so a device that is convenient for controlling the catheter A5 is needed. The catheter A5 is installed on the traction device 1, and the position of the catheter A5 adapted thereto is changed by the adjustment unit 101, and the clamping strength of the catheter A5 is adjusted. The catheter A5 is inserted into the inner hole of the fixing sleeve 302, passes through the first avoidance hole 5, the second avoidance hole 204 and the guide groove 9 in sequence and is inserted into the penis A4. After the catheter A5 is inserted, the fixing nut 304 is first screwed inward. During the process of screwing the fixing nut 304 in, the outer thread 303 of the fixing sleeve is squeezed. At this time, the gaps between the four openings 305 on the fixing sleeve 302 become smaller. When the fixing sleeve 302 locks the catheter A5 and does not slide, the screwing of the fixing nut 304 can be stopped, and a soft material (for example, soft glue, silicone, etc.) can be set in the inner wall of the fixing sleeve 302; due to the different thicknesses of the catheters A5, the outer wall of the catheter A5 is prevented from being damaged during the locking process. The setting of the openings 305 and the fixing nut 304 facilitates the fixing sleeve 302 to fix catheters A5 of multiple 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 adjustment sleeve 201 is rotated inward, the elastic member 203 is deformed, and the elastic member 203 uses a spring. The spring is shortened, and the adjustment sleeve 201 moves toward the seesaw 7. Since the external thread 202 of the adjustment sleeve cooperates with the internal thread 4 of the mounting sleeve, the adjustment sleeve 201 and the mounting sleeve 301 are connected by threads. When the adjustment sleeve 201 moves toward the seesaw 7, the mounting sleeve 301 obtains a reaction force and moves in the opposite direction of the adjustment 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 obtains traction, so that the catheter A5 moves and drives the expansion balloon to reach the bladder neck A1. The expansion balloon on the catheter A5 compresses the bleeding part of the bladder neck A1 to stop bleeding. The threaded arrangement makes it easy for the nurse to adjust the position between the installation sleeve 301 and the adjustment sleeve 201, thereby adjusting the position of the catheter A5. During the adjustment process, the catheter A5 is always locked by the fixing sleeve 302, thereby ensuring the stability of the catheter A5 when being pulled.

[0077] Embodiment 2:

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

[0079] Furthermore, it also includes an extension piece 10, which can be adjustably 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 arranged at the bottom end of the extension piece 10; and a threaded column 12, which is fixedly connected to the lower end surface of the protrusion 11.

[0080] Furthermore, it also includes a slide groove 13, which is arranged on the protective sheet 6, and a protrusion 11 is slidably installed inside; an annular groove 14, which is arranged on the slide groove 13, and a threaded column 12 is inserted inside; and an adjusting nut 15, which is adjustably installed on the threaded column 12.

[0081] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the adjustment unit 101 is installed on the protection unit 102, the protection unit 102 protects the penis A4, and the penis A4 is placed on the protection sheet 6, which can also play a supporting effect. Since the lengths of the penis A4 of different men are different, the overall length of the protection sheet 6 needs to be set to be adjustable. At the rear end of the protection sheet 6, close to the fixing unit 103, an adjustable extension sheet 10 is added. When the overall length of the protection sheet 6 needs to be adjusted, first loosen the adjusting nut 15, and then tighten the adjusting nut 15. The nut 15 moves downward along the threaded column 12. At this time, the upper end surface of the adjusting nut 15 does not fit the lower bottom surface of the protective sheet 6. The locking force between the protective sheet 6 and the extension sheet 10 is lost. When the protective sheet 6 is pulled outward, the overall length of the protective sheet 6 and the extension sheet 10 is lengthened. When the protective sheet 6 is pushed inward, the overall length of the protective sheet 6 and the extension sheet 10 is shortened. During the movement of the protective sheet 6, the protrusion 11 moves along the slide groove 13. When the threaded column 12 moves in the annular groove 14 and is adjusted to a suitable length, the adjusting nut 15 is tightened upward. A water-absorbing and anti-inflammatory dressing can be placed on the inner side of the seesaw 7 of the protective sheet 6 to protect and reduce inflammation of the glans penis.

[0082] Embodiment 3:

[0083] like Figure 4-6 , Figure 9-11 As 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 two sides of the rear end of the extension piece 10; 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 arranged on each mounting post 17; a pair of positioning holes 19, which are respectively arranged on the inner wall of each mounting groove 18 and connected to the outside of the mounting post 17.

[0084] Furthermore, the fixing unit 103 includes a support plate 20, which fits in the pubic area of ​​the lower abdomen of the human body; a pair of connecting columns 21, which are respectively arranged on the support plate 20, respectively installed in each installation groove 18, and located at the toe joint corresponding to the support plate 20; a pair of movable grooves 22, which are respectively arranged on each connecting column 21; a pair of compression springs 23, which are respectively installed in each movable groove 22; a pair of locking beads 24, which are respectively movably installed in each movable groove 22, and half of them are exposed outside the movable groove 22; wherein, both 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 present application, due to the adoption of the above-mentioned structure, the combined adjustment unit 101 and protection unit 102 are detachably mounted on the fixing unit 103, the support plate 20 is fitted to the pubic area of ​​the lower abdomen of the human body, the lower ends of the support plate 20 are located at the symphysis of the metatarsals, a pair of connecting columns 21 are arranged on the support plate 20, and the pair of connecting columns 21 are respectively located at the pubic symphysis corresponding to the support plate 20, and mounting columns 17 are respectively arranged on both sides of the connecting plate 16 of the extension plate 10, and each connecting column 21 is respectively installed in the mounting groove 18 of each mounting column 17. During installation, hold each mounting post 17 with two hands respectively, and align the mounting groove 18 of each mounting post 17 with each connecting post 21. During the process of inserting the connecting post 21 into the mounting groove 18, the side wall of the mounting groove 18 squeezes the locking bead 24, causing the locking bead 24 to move along the movable groove 22. At this time, the compression spring 23 is shortened. When the connecting post 21 is inserted into the movable groove 22 and corresponds to the positioning hole 19, the locking bead 24 loses its squeezing, and the compression spring 23 resets and pushes the locking bead 24 outward to move along the outside of the movable groove 22. The locking bead 24 moves outward and moves one-third into the positioning hole 19. The locking bead 24 positions the mounting post 17 and ensures the connection between the connecting post 21 and the mounting post 17. When disassembling, pinch each mounting column 17 with both hands and pull the mounting column 17 outward. During the pulling process of the mounting column 17, the inner wall of the mounting groove 18 squeezes the locking bead 24, so that the locking bead 24 moves into the movable groove 22. The locking bead 24 disengages from the positioning hole 19, and the mounting column 17 loses connection with the connecting column 21. The mounting column 17 can be directly removed from the connecting column 21. The setting of the locking bead 24, the compression spring 23 and the positioning hole 19 makes it convenient for nurses to remove the adjustment unit 101 and the protection unit 102 from the wearable device, which is also convenient for patients to wear.
