Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an adjustable fixing patch for urinary catheters. Background Technology

[0002] In clinical practice, in order to meet various diagnostic and treatment needs, medical staff often need to perform indwelling catheterization. Indwelling catheterization involves inserting a catheter through the urethra into the bladder to empty the urine. It is suitable for situations where patients cannot urinate voluntarily or need to accurately monitor urine output. To ensure the stability of the catheter and to prevent additional discomfort or damage to the patient, specially designed catheter fixation clips are often used for fixation.

[0003] Existing catheter fixation dressings have several shortcomings, such as unstable fixation, easy slippage of the catheter, excessively rigid materials unsuitable for skin adhesion, limited adhesion angles, and high cost. They are particularly prone to detachment, leading to catheter displacement or accidental removal. When the patient moves, the distal end of the catheter may shift due to traction, causing the distal end to deviate, resulting in additional pain and affecting fixation effectiveness. This not only reduces patient comfort and treatment safety but may also lead to prolonged hospital stays and increased medical costs. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an adjustable fixing patch for urinary catheters.

[0005] An adjustable fixing adhesive for a urinary catheter includes a soft rubber block, a first fixing band, a second fixing band, a first hook and loop fastener, a second hook and loop fastener, a ball seat, a universal ball, a connecting block, and a clamping assembly. The first fixing band is connected to one side of the soft rubber block, and the second fixing band is connected to the other side of the soft rubber block. The first hook and loop fastener is connected to the first fixing band, and the second hook and loop fastener is connected to the second fixing band. The ball seat is connected to the soft rubber block, the universal ball is mounted on the ball seat, the connecting block is connected to the universal ball, and the clamping assembly is connected to the connecting block.

[0006] Preferably, the clamping assembly includes a slider, a fixing block, and a spring. Two sliders are slidably connected to the connecting block, and springs are connected between each slider and the connecting block. Fixing blocks are connected to each slider.

[0007] Preferably, the clamping assembly includes a button block, with the button block slidably connected to both the front and rear sides of the connecting block. Both sides of the button block are inclined surfaces, and the area of ​​the side of the two button blocks that are close to each other is smaller than the area of ​​the side that is far away from each other. The inclined surfaces of the button blocks are in contact with the slider.

[0008] Preferably, the clamping assembly includes rubber pads, and the sides of the fixing blocks that are close to each other are connected to rubber pads.

[0009] Preferably, it also includes anti-slip pads, with anti-slip pads connected to the inner walls of both the first and second fixing straps.

[0010] Preferably, the first fixing strap, the second fixing strap, the first hook and loop fastener, and the second hook and loop fastener all have ventilation holes.

[0011] The beneficial effects of this utility model are as follows: This utility model is provided with a ball seat, a universal ball and a clamping component. The universal ball allows the clamping component to be freely adjusted in multiple directions, and the catheter can be fixed at any angle as needed, improving the flexibility of the clamping component.

Detailed Implementation

[0018] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0019] An adjustable fixing adhesive for urinary catheters, such as Figures 1-5As shown, the assembly includes a soft rubber block 1, a first fixing strap 2, a second fixing strap 3, a first hook and loop fastener 4, a second hook and loop fastener 5, a ball seat 6, a universal ball joint 7, a connecting block 8, a clamping assembly, and an anti-slip pad 14. The soft rubber block 1 is fixedly connected to the first fixing strap 2 on one side and to the second fixing strap 3 on the other side. The first fixing strap 2 is fixedly connected to the outer wall of the first hook and loop fastener 4, and the second fixing strap 3 is fixedly connected to the inner wall of the second hook and loop fastener 5. Ventilation holes 15 are provided on the first fixing strap 2, the second fixing strap 3, the first hook and loop fastener 4, and the second hook and loop fastener 5. The ventilation holes 15 help keep the patient's skin dry, reduce stuffiness and moisture buildup caused by prolonged application, and improve patient comfort. The top of the soft rubber block 1 is fixedly connected to a ball seat 6, the ball seat 6 is mounted on top of a universal ball 7, the universal ball 7 is fixedly connected to a connecting block 8, and the connecting block 8 is connected to a clamping component. The inner walls of the first fixing band 2 and the second fixing band 3 are both fixedly connected to anti-slip pads 14. The anti-slip pads 14 can increase the friction between the first fixing band 2 and the second fixing band 3 and the patient's thigh, preventing the fixing patch from shifting when the patient moves.

[0020] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping assembly includes a slider 9, a fixing block 10, a spring 11, a pressing block 13, and a rubber pad 12. Two sliders 9 are slidably connected to the connecting block 8. Springs 11 are fixedly connected between the sliders 9 and the connecting block 8. Fixing blocks 10 are fixedly connected to each slider 9. Pressing blocks 13 are slidably connected to both the front and rear sides of the connecting block 8. The left and right sides of the pressing blocks 13 are both inclined surfaces. The area of ​​the side of the two pressing blocks 13 that is close to each other is smaller than the area of ​​the side that is far away from each other. The inclined surfaces of the pressing blocks 13 are in contact with the sliders 9. Rubber pads 12 are fixedly connected to the side of the fixing blocks 10 that is close to each other.

[0021] Initially, spring 11 is in its normal state, and the two fixing blocks 10 are close to each other. When it is necessary to fix the urinary catheter, the first fixing strap 2 and the second fixing strap 3 are first wrapped around the patient's thigh. Under the adhesive action of the first Velcro 4 and the second Velcro 5, the first fixing strap 2 and the second fixing strap 3 are fixed to the patient's thigh. At the same time, the two pressing blocks 13 are pressed down to make them slide closer to each other. The inclined surface of the pressing block 13 squeezes the slider 9, causing the two sliders 9 to slide away from each other. Spring 11 is compressed, and the two fixing blocks 10 move away from each other. The urinary catheter is placed between the two fixing blocks 10. The pressing block 13 is released, and the pressing block 13 no longer squeezes the slider 9. Spring 11 returns to its original state. Under the elastic force of spring 11, the two sliders 9 slide closer to each other, and the two fixing blocks 10 move away from each other. The moving parts clamp the catheter closer together, thus securing it in place. The rubber pad 12 increases the friction between the fixing block 10 and the catheter, preventing the catheter from sliding between the two fixing blocks 10. The omnidirectional ball 7 allows the clamping assembly to be freely adjusted in multiple directions, enabling the catheter to be fixed at any angle as needed. This improves the flexibility of the clamping assembly and reduces discomfort or injury to the patient's skin or body caused by improper catheter fixation. When the patient moves, the catheter may be pulled and shift. With the help of the omnidirectional ball 7, the angle of the clamping assembly can be freely adjusted according to the patient's position and movement, keeping the catheter in a relatively stable position and reducing the risk of catheter displacement or accidental pulling due to patient movement.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
