Description

Technical Field

[0001] The utility model relates to the technical field of elbow urinary catheters, in particular to an elbow urinary catheter with an anti-slip structure. Background Art

[0002] A urinary catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) that can be inserted into the bladder through the urethra to guide urine out. After the catheter is inserted into the bladder, there is an air bag near the tip of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine.

[0003] During actual operation, the catheter usually swings with the patient's body movements, and the swing amplitude of the catheter increases synchronously with the increase of the patient's movement amplitude. The spring clip used to elastically clamp the catheter cannot make an adaptive position change with the swing of the catheter. Therefore, as the patient moves, the catheter is at risk of slipping between the two spring clips.

[0004] The existing patent (publication number: CN220877495U) is a kind of anti-falling catheter holder. The utility model connects the elastic clip used for clamping the catheter to the seat body rotatably through a rotating connector. When the patient moves while using the anti-falling catheter holder and drives the catheter to swing, the elastic clip can make adaptive changes in position following the swing of the catheter, thereby reducing the risk of the catheter falling off during use.

[0005] In view of the above problems, existing patents have provided solutions, but some existing structures for fixing and preventing the elbow catheter from falling off do not have a buffer structure. When the external urine bag connecting tube is connected to the elbow catheter and is accidentally pulled, the connecting port is prone to loosening or slipping, causing urine leakage.

[0006] Therefore, an elbow urinary catheter with an anti-slip structure is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 , the utility model provides a technical solution:

[0027] An elbow urinary catheter with an anti-slip structure comprises an elbow urinary catheter body 1, a base material 5 is arranged at the bottom of the elbow urinary catheter body 1, buffer mechanisms 4 are arranged on both sides of the top of the base material 5, a fixing frame 2 is arranged at the top of the base material 5, and a clamping mechanism 6 is arranged inside the fixing frame 2;

[0028] The buffer mechanism 4 includes a slide rail 401, an elastic rubber strip 402, a slide bar 403 and a slide plate 404. The bottom of the slide rail 401 is fixedly connected to the top of the substrate 5, the rear side of the elastic rubber strip 402 is fixedly connected to the rear side of the inner wall of the slide rail 401, the front side of the elastic rubber strip 402 is fixedly connected to the rear side of the slide bar 403, the slide bar 403 is slidably connected to the inside of the slide rail 401, and the side of the slide bar 403 close to the slide plate 404 is fixedly connected to the slide plate 404.

[0029] In this embodiment: the elbow urinary catheter body 1 is clamped by the first clamp ring 603 and the second clamp ring 10, and then the base material 5 is adhered to the skin surface by the hydrocolloid medical double-sided adhesive tape 8, and then the connecting tube of the external urine bag is connected to the elbow urinary catheter body 1. At this time, when the external urine bag is pulled, the slide bar 403 slides forward inside the slide plate 404, and the elastic rubber pull strip 402 is extended and deformed to buffer the external force and reduce the direct impact on the elbow urinary catheter body 1, thereby reducing the risk of loosening and falling off of the interface between the elbow urinary catheter body 1 and the external urine bag connecting tube.

[0030] Specifically, Figure 4 As shown, the clamping mechanism 6 includes a rotating column 601, a clamping plate 602 and two first clamping rings 603. The rotating column 601 is threadedly connected to the inside of the fixing frame 2. The surface of the clamping plate 602 is in movable contact with the inner wall of the fixing frame 2. The top of the first clamping ring 603 is fixedly connected to the bottom of the clamping plate 602.

[0031] Specifically, Figure 2 and Figure 4 As shown, the second clamp ring 10 is fixedly connected to both sides of the top of the slide plate 404, the first clamp ring 603 is in contact with the top of the second clamp ring 10, the inner walls of the first clamp ring 603 and the second clamp ring 10 are fixedly connected with the anti-sliding block 11, the number of the anti-sliding block 11 is several and evenly distributed on the inner walls of the first clamp ring 603 and the second clamp ring 10, and the surface of the elbow catheter body 1 is in contact with the surface of the anti-sliding block 11.

[0032] Specifically, Figure 4 As shown, a bearing 7 is provided at the bottom of the rotating column 601 , the surface of the rotating column 601 is fixedly connected to the inner wall of the bearing 7 , and the bottom of the outer wall of the bearing 7 is fixedly connected to the top of the clamping plate 602 .

[0033] Specifically, Figure 4 As shown, a screw block 3 is fixedly connected to the top of the rotating column 601 .

[0034] In this embodiment: by moving the elbow catheter body 1 to the inside of the first clamp ring 603 and the second clamp ring 10, and then holding the screw block 3 to rotate the rotating column 601, the rotating column 601 is threadedly connected to the inside of the fixing frame 2, and when the rotating column 601 rotates, the rotating column 601 can be moved downward, which can drive the clamping plate 602 and the first clamp ring 603 to move downward, so that the bottom of the first clamp ring 603 contacts the top of the second clamp ring 10, and the elbow catheter body 1 can be clamped. By contacting the anti-sliding block 11 with the surface of the elbow catheter body 1, the first clamp ring 603 and the second clamp ring 10 can clamp the elbow catheter body 1 more stably.

[0035] Specifically, Figure 5 As shown, a hydrocolloid medical double-sided adhesive tape 8 is fixedly connected to the bottom of the substrate 5, and the material of the substrate 5 is a polyvinyl chloride film.

[0036] Specifically, Figure 5 As shown, both the substrate 5 and the hydrocolloid are provided with ventilation holes 9 , the number of ventilation holes 9 is several and evenly distributed inside the substrate 5 and the hydrocolloid, and the top ventilation holes 9 are connected to the bottom ventilation holes 9 .

[0037] In this embodiment, the hydrocolloid medical double-sided adhesive tape 8 at the bottom of the substrate 5 can firmly adhere the substrate 5 to the patient's body, thereby fixing the elbow catheter body 1. The air holes 9 provided inside the substrate 5 and the hydrocolloid allow air to circulate, thereby reducing skin discomfort. The top and bottom air holes 9 are connected, thereby ensuring a ventilating effect.

[0038] Working principle: Move the elbow catheter body 1 between the first clamp ring 603 and the second clamp ring 10, then hold the screw block 3 to rotate, the screw block 3 can drive the rotating column 601 to rotate, the rotating column 601 is connected with the internal thread of the fixing frame 2, and the rotating column 601 can move when the rotating column 601 rotates. The bottom of the rotating column 601 is rotatably connected with the clamp plate 602 through the bearing 7, so that the clamp plate 602 is prevented from rotating with the rotating column 601, and the clamp plate 602 is convenient to move up and down inside the fixing frame 2 The rotating column 601 is rotated to move the clamping plate 602 downward, driving the first clamping ring 603 close to the second clamping ring 10 on the top of the slide plate 404. The first clamping ring 603 and the second clamping ring 10 work together to clamp the elbow catheter body 1. The multiple anti-sliding blocks 11 on the inner walls of the first clamping ring 603 and the second clamping ring 10 increase the friction with the surface of the elbow catheter body 1, further preventing the elbow catheter body 1 from slipping off. Then, the connecting tube of the external urine bag is connected to the elbow catheter body 1. When the external urine bag is accidentally pulled, the slide plate 404 will drive the slide bar 403 to move in the slide rail 401. At this time, the elastic rubber pull strip 402 will be stretched, and the elastic deformation of the elastic rubber pull strip 402 is used to buffer the external force, reduce the direct impact on the elbow catheter body 1, and thus reduce the risk of loosening and falling off of the interface between the elbow catheter body 1 and the external urine bag connecting tube. The substrate is made of polyvinyl chloride soft film, which has certain softness and adaptability. The hydrocolloid medical double-sided adhesive 8 at the bottom of the substrate can firmly adhere the substrate to the patient's body to fix the elbow catheter body 1. The air holes 9 opened inside the substrate and the hydrocolloid allow air to circulate and reduce skin discomfort. The top and bottom air holes 9 are connected to ensure the ventilation effect, avoiding the existing partial structure for fixing and preventing the elbow catheter from falling off. The structure does not have a buffer structure. When the external urine bag connecting tube is accidentally pulled after being connected to the elbow catheter, the connection port is prone to loosening or slipping, resulting in urine leakage.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
