Description

Technical Field

[0001] This utility model relates to the field of urinary catheter technology, specifically a urinary catheter with a self-fixing structure. Background Technology

[0002] A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. It is usually made of natural rubber, silicone rubber, or polyvinyl chloride. In clinical practice, many patients need catheterization because they are unable to urinate on their own under various circumstances. In such cases, a urinary catheter is used to help the patient urinate.

[0003] According to Chinese Patent Publication No. CN216022353U, a urinary catheter with a directional fixing structure is disclosed, including a catheter body. An annular fixing seat is fixedly sleeved on the outer wall of the catheter body. Two straps are fixedly connected to the outer wall of the annular fixing seat. The two straps are symmetrically arranged, and each strap has a breathable micropore. A left connecting strip and a right connecting strip are fixedly installed at the ends of the two straps that are far apart from each other. This utility model has a reasonable design and good practicality. The two straps facilitate the binding and fixing of the catheter body to a suitable position on the patient's thigh. The operation is simple and convenient, and the catheter body is firmly fixed, preventing it from falling off. Moreover, when the two straps come into contact with the patient's thigh skin, they have good softness, comfort, sweat absorption, breathability, and antibacterial properties. Furthermore, the two straps are easy to remove from the patient's leg without causing skin injury or pain.

[0004] Traditional urinary catheters are usually secured with tape or simple fastening straps. However, during use, they are prone to displacement or dislodgement due to patient movement or the weight of the catheter itself, leading to urine leakage and increasing the risk of infection. Traditional fixation methods are also inconvenient to adjust, especially when it is necessary to adjust the position of the catheter or the length of the fastening strap, which is cumbersome and prone to errors. Utility Model Content

[0005] The purpose of this invention is to provide a urinary catheter with a built-in fixing structure, which can avoid the inconvenience of traditional fixing methods, especially when it is necessary to adjust the position of the urinary catheter or the length of the fixing strap, which is cumbersome and prone to errors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a urinary catheter with a self-fixing structure, comprising a urinary catheter body, characterized in that: a fixing sleeve is fitted on the tube body of the urinary catheter body, a plurality of limiting plates are movably arranged at the upper end of the fixing sleeve, one end of the plurality of limiting plates is fitted to the tube body of the urinary catheter body, a perforation is opened on one side of the fixing sleeve, a fixing strap is movably arranged in the perforation, a fixing buckle is provided at one end of the fixing strap, the other end of the fixing strap extends outward through the fixing buckle, an opening is opened on one side of the fixing buckle, a positioning block is slidably arranged in the opening, and the positioning block engages with a buckle groove opened at one end of the fixing strap.

[0007] As a preferred embodiment of the urinary catheter with a self-fixing structure according to this utility model, the fixing sleeve is provided with an elastic column inside.

[0008] As a preferred embodiment of the urinary catheter with a self-fixing structure according to this utility model, a limiting sleeve is provided on the upper side of the fixing sleeve, the limiting sleeve restricts the limiting plate, and a spring is provided on the inner side of the limiting plate.

[0009] As a preferred embodiment of the urinary catheter with a self-fixing structure of this utility model, the positioning block is provided with end plates at both the upper and lower ends, and the end plates are provided with sliding grooves. The fixing blocks provided on the upper and lower sides of the fixing buckle are slidably disposed in the sliding grooves, and a spring is connected between the inner side of the sliding groove and the fixing block.

[0010] As a preferred embodiment of the urinary catheter with a self-fixing structure of this utility model, hollow rods are symmetrically arranged at both ends of the fixing buckle, and pull rods are symmetrically arranged at both ends of the end plate. The pull rods are slidably connected to the hollow rods, and a spring is connected between the pull rods and the inner wall of the hollow rods.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a fixing sleeve fitted onto the catheter body, allowing the catheter body to slide within the fixing sleeve and adjust its fixed position. At the same time, the elastic column inside the fixing sleeve contacts the catheter body, increasing friction and improving the stability of the fixing sleeve. Combined with the limiting plate contacting the catheter body at one end to prevent the catheter body from sliding freely, the fixing strap is used to fix the catheter body to the patient's leg, further improving the stability of the catheter.

[0013] 2. This utility model uses a spring to cause the positioning block to engage in the corresponding buckle groove, so that the fixing strap is fixed to the patient's leg. This not only makes it easy to adjust the length of the fixing strap, but also eliminates the need for tape, thus preventing damage to the patient's skin. Attached Figure Description

[0020] Please refer to Figure 1-Figure 5 This utility model provides a urinary catheter with a built-in fixing structure, including a urinary catheter body 1, a fixing sleeve 2 fitted on the tube of the urinary catheter body 1, and the urinary catheter body 1 can slide within the fixing sleeve 2, thereby adjusting the fixing position of the urinary catheter body 1.

[0021] In order to prevent the catheter body 1 from sliding freely when not adjusting, multiple limiting plates 5 are movably provided at the upper end of the fixing sleeve 2. The multiple limiting plates 5 are conical in structure, and springs 6 are provided on the inner side of the limiting plates 5. The springs 6 contact the catheter body 1 to avoid squeezing the catheter body 1 when fixing it.

[0022] In this arrangement, one end of each of the multiple limiting plates 5 is attached to the tube body of the catheter body 1, and a limiting sleeve 7 is provided on the upper side of the fixing sleeve 2. The limiting sleeve 7 restricts the limiting plates 5, causing one end of the limiting plates 5 to be attached to the catheter body 1, thus preventing the catheter body 1 from sliding freely.

[0023] Furthermore, an elastic post 4 is provided inside the fixing sleeve 2. After the elastic post 4 comes into contact with the catheter body 1, it increases the friction and further prevents the catheter body 1 from sliding at will.

[0024] like Figure 2 As shown, a perforation 3 is provided on one side of the fixing sleeve 2, and a fixing strap 8 is movably installed in the perforation 3. A fixing buckle 9 is provided at one end of the fixing strap 8, and the other end of the fixing strap 8 extends to the outside through the fixing buckle 9. The fixing strap 8 is used to fix the catheter body 1 to the patient's leg to prevent the catheter body 1 from separating from the patient.

[0025] It is worth noting that an opening 10 is provided on one side of the fixing buckle 9, and a positioning block 11 is slidably disposed in the opening 10. Both ends of the positioning block 11 are provided with end plates 12, which are located on the upper and lower sides of the fixing buckle 9, respectively. A sliding groove 13 is provided on the end plate 12, and the fixing blocks 15 provided on the upper and lower sides of the fixing buckle 9 are slidably disposed in the sliding groove 13. The fixing blocks 15 can prevent the positioning block 11 from separating from the fixing buckle 9. At the same time, through the sliding cooperation between the sliding groove 13 and the fixing block 15, the positioning block 11 can be moved away from the buckle groove 19. At this time, the length of the fixing strap 8 can be adjusted. When the positioning block 11 and the buckle groove 19 are engaged, the fixing strap 8 can be fixed.

[0026] A spring 14 is connected between the inner side of the slide groove 13 and the fixing block 15, which can improve the stability of the positioning block 11 in the latching groove 19.

[0027] like Figure 5 As shown, hollow rods 16 are symmetrically arranged at both the upper and lower ends of the fixing buckle 9, and pull rods 18 are symmetrically arranged at both the upper and lower ends of the end plate 12. The pull rods 18 are slidably connected to the hollow rods 16, and a spring 17 is connected between the pull rods 18 and the inner wall of the hollow rods 16. The pull rods 18 and the spring 17 can not only improve the stability of the positioning block 11, but also make the positioning block 11 more stable in the buckle groove 19.

[0028] In summary, the working principle of the urinary catheter with a built-in fixing structure according to this utility model embodiment is as follows: the limiting plate 5 is bent outward so that the limiting plate 5 does not contact the urinary catheter body 1. At this time, the fixing position of the urinary catheter body 1 can be adjusted. The limiting plate 5 is then used to restrict the urinary catheter body 1 to prevent it from sliding freely. After the fixing strap 8 is wrapped around the patient's leg, one end of it is passed through the fixing buckle 9 and the positioning block 11 is used to lock it in the buckle groove 19 to fix the fixing strap 8 and improve the stability of the urinary catheter body 1.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
