Description

Technical Field

[0001] This utility model relates to the field of urinary catheter technology, specifically a urinary catheter with a tube body storage and fixing structure. Background Technology

[0002] A urinary catheter is a medical device primarily used to drain urine from the bladder of patients with urinary dysfunction. It is a long, thin tubular device inserted into the bladder through the urethra, allowing urine to drain from the body through the tube. Catheters are typically made of soft materials such as rubber, latex, silicone rubber, or polyvinyl chloride (PVC), possessing characteristics such as flexibility, durability, and biocompatibility to reduce irritation and damage to the urethra. Different types of catheters are suitable for different patients and clinical situations. For example, silicone rubber catheters are widely used for patients requiring long-term indwelling catheters due to their excellent biocompatibility and corrosion resistance, while latex catheters are suitable for temporary catheterization due to their softness and good elasticity. PVC catheters are often used for disposable catheterization due to their low price and simple manufacturing process.

[0003] Chinese Patent CN213554161U discloses a urinary catheter, including a catheterization chamber and a water injection chamber. The catheter has a balloon at its front end that communicates with the water injection chamber. An upper urine outlet in front of the balloon communicates with the catheterization chamber, and a lower urine outlet behind the balloon communicates with the catheterization chamber. The catheter body is marked with graduations. A pressure-indicating balloon is located on one side of the water injection chamber inlet, communicating with the water injection chamber. One side of the pressure-indicating balloon has three circular membrane structures of different colors, each capable of withstanding different pressures. The bulge of each colored membrane indicates a different pressure limit. A certain amount of liquid is injected through the water injection chamber inlet to inflate the balloon, positioning it within the bladder to prevent catheter dislodgement.

[0004] While the above-mentioned solutions can minimize residual urine in the bladder, these catheters are typically secured with tape, which offers limited stability and is uncomfortable. Furthermore, the drainage tube of the catheter lacks effective storage when the patient moves around, making it inconvenient for the patient. Therefore, these solutions do not meet current needs. To address this, we propose a catheter with a tube storage and fixation structure. Utility Model Content

[0005] The purpose of this utility model is to provide a urinary catheter with a tube body storage and fixing structure to solve the problems mentioned in the background art, such as the urinary catheter fixing method being prone to falling off and causing discomfort when walking, and the lack of effective storage of the urinary catheter drainage tube when walking, which leads to inconvenience when walking.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a urinary catheter with a tube body storage and fixing structure, comprising an arc-shaped block, a storage box provided at the front end of the arc-shaped block, a urinary catheter body provided on one side inside the storage box, a first binding strap provided on one side of the arc-shaped block, a second binding strap provided at the other end of the arc-shaped block, a storage groove provided on one side inside the storage box, and one end of the urinary catheter body extending into the storage groove.

[0007] Preferably, the rear end faces of both the first and second straps are adhered and fixed with an antibacterial layer, and the antibacterial layer is made of nano-silver ion fiber material.

[0008] Preferably, the first strap, the second strap, and the antibacterial layer are all provided with a plurality of air vents arranged in a rectangular array.

[0009] Preferably, a skin-friendly layer is adhered and fixed to the rear end face of the arc-shaped block, and the skin-friendly layer is made of medical-grade silicone.

[0010] Preferably, two grooves are provided on one side of the front end of the first strap, and Velcro is glued and fixed inside the grooves. Two elastic bands are provided on one side of the second strap, and Velcro is glued and fixed on one side of the rear end of each elastic band.

[0011] Preferably, a connecting plate is provided on the front and rear sides of the inside of the storage slot. Three equidistant semi-circular clamping blocks are glued and fixed on the inner side of the connecting plate. Two sets of equidistant return springs are provided between the connecting plate and the storage slot, and each set of return springs has two springs. One end of each return spring is connected to the storage slot, and the other end of each return spring is connected to the connecting plate.

[0012] Preferably, an extension block is provided at the middle position on one side of the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a first strap on one side of an arc-shaped block and a second strap on the other side. The arc angle of the arc-shaped block can fit the patient's diaphragm well. The second strap's rear end is attached to the first strap's front end via a Velcro fastener. The strong adhesion and adjustability of the Velcro ensure stability even during patient movement, preventing the catheter from easily falling off. In contrast, adhesive tape often leaves residue on the patient's skin, making cleaning difficult and potentially causing allergic reactions such as redness and itching. Velcro avoids this problem, causing no damage or discomfort to the patient's skin, thus enhancing patient comfort and satisfaction during treatment.

[0015] 2. This utility model features a skin-friendly layer adhered to the rear end of the arc-shaped block, and an antibacterial layer adhered to the rear ends of both the first and second straps. The first strap, second strap, and the wear-resistant plate of the antibacterial layer all have ventilation holes. The skin-friendly layer is made of medical-grade silicone, which is non-toxic, odorless, and hypoallergenic, allowing it to gently conform to the patient's skin, reducing friction and irritation, making it particularly suitable for prolonged wear. The antibacterial layer is made of nano-silver ion fiber material, preventing bacterial growth after wearing. The ventilation hole design not only enhances the material's breathability, allowing air to circulate freely and reducing sweat accumulation, but also greatly improves wearing comfort. Even during prolonged wear or high-intensity activity, patients can keep their skin dry, avoiding discomfort or skin problems caused by sweat retention.

[0016] 3. This utility model features a storage slot on one side of the storage box. When the patient needs to move around, the drainage tube of the urinary catheter can be moved into the storage slot. The return spring, with its good elasticity, can automatically adjust and restore its shape, providing continuous thrust to the connecting plate. The connecting plate will drive the semi-circular clamp to clamp and fix the urinary catheter body. The patient does not need to worry about the drainage tube affecting their movement due to shaking or swaying during walking, nor does the patient need to worry about the embarrassment and inconvenience caused by the lack of a suitable storage method.

[0024] In use, insert one end of the catheter body 17 into the patient's urethra, with the arc-shaped block 1 pressed tightly against the patient's thigh skin. Then, wrap the first strap 8 and the second strap 9 around the thigh at the appropriate position. The elastic band 12 conforms to the leg due to its elasticity, with one end inserted into the groove 10. The Velcro 13 and Velcro 11 are attached and fixed together. The strong adhesion and adjustability of the Velcro ensure that the catheter body 17 is stable and does not fall off. The skin-friendly layer 15 and the antibacterial layer 16 contact the skin, reducing friction and irritation and inhibiting bacterial growth. The vent 14 ensures air circulation and keeps the skin dry. When the patient walks, the drainage tube of the catheter body 17 can be placed into the storage slot 3. The return spring 4 drives the connecting plate 5 to move the semi-circular clamp 7 to clamp and fix the drainage tube. When removing it, the connecting plate 5 is moved by the extension block 6, squeezing the return spring 4, so that the semi-circular clamp 7 releases the drainage tube. The operation is simple and quick.

[0025] Please see Figure 2 and Figure 3 The rear ends of the first strap 8 and the second strap 9 are both bonded with an antibacterial layer 16, which is made of nano-silver ion fiber material. Nano-silver ion fiber material has excellent antibacterial properties, which can effectively inhibit bacterial growth, reduce the risk of cross-infection, and provide patients with a safer and more hygienic wearing environment.

[0026] Please see Figure 1 The first strap 8, the second strap 9, and the antibacterial layer 16 are all provided with a number of rectangular array-distributed ventilation holes 14. The ventilation holes 14 can enhance the breathability of the material, promote air circulation, reduce sweat accumulation, keep the skin dry, and improve the patient's wearing comfort.

[0027] Please see Figure 2 and Figure 3The rear end face of the arc-shaped block 1 is bonded and fixed with a skin-friendly layer 15, which is made of medical-grade silicone. Medical-grade silicone has the characteristics of being non-toxic, odorless, and hypoallergenic, and can gently fit the patient's skin, reduce friction and irritation, and bring the patient a more comfortable and safe wearing experience.

[0028] Please see Figure 1 , Figure 2 and Figure 4 Two grooves 10 are provided on one side of the front end of the first strap 8. Velcro 13 is glued and fixed inside the grooves 10. Two elastic bands 12 are provided on one side of the second strap 9. Velcro 11 is glued and fixed on one side of the rear end of each elastic band 12. The Velcro design makes the strap fixing easier and faster. At the same time, the elasticity of the elastic band 12 can ensure that the strap fits tightly to the patient's leg, improving the stability and comfort of the fixation.

[0029] Please see Figure 2 The front and rear sides of the storage slot 3 are provided with connecting plates 5. Three equally spaced semi-circular clamping blocks 7 are glued and fixed to the inner side of each connecting plate 5. Two sets of equally spaced return springs 4 are provided between the connecting plate 5 and the storage slot 3. Each set of return springs 4 has two springs. One end of each return spring 4 is connected to the storage slot 3, and the other end of each return spring 4 is connected to the connecting plate 5. The cooperation of the return springs 4 and the semi-circular clamping blocks 7 can achieve stable clamping and fixing of the drainage tube, preventing the drainage tube from affecting movement due to shaking or swinging during walking. At the same time, the elasticity of the return springs 4 makes the clamping process more gentle and will not damage the drainage tube.

[0030] Please see Figure 2 An extension block 6 is provided at the middle position on one side of the connecting plate 5. The design of the extension block 6 makes it easier for the user to grasp and move the connecting plate 5, thereby realizing the squeezing of the reset spring 4 and the release of the semi-circular clamp 7. The whole operation process is simple and convenient.

[0031] Working principle: In use, after inserting one end of the catheter body 17 into the patient's urethra, the outer wall of the arc-shaped block 1 contacts the skin of the patient's thigh. The first strap 8 and the second strap 9 are wrapped around the appropriate position on the patient's thigh. At this time, the elastic band 12 can fit well against the patient's leg, and one end of the elastic band 12 is inserted into the groove 10, so that the Velcro 13 and the Velcro 11 are adhered and fixed. The strong adhesion and adjustability between the Velcro ensure that it remains stable even when the patient is moving, and the catheter body is not easy to fall off. When the catheter body 17 is fixed, the skin-friendly layer 15 and the antibacterial layer 16 will adhere to the patient's skin, reducing friction and irritation, inhibiting bacterial growth, and greatly improving the comfort during wear. The ventilation holes 14 allow for free air circulation, reducing sweat buildup, keeping the skin dry, and preventing discomfort or skin problems caused by sweat retention. When the patient needs to move around, the drainage tube of the catheter body 17 can be moved into the storage slot 3. Through the elastic action of the front and rear return springs 4, the connecting plate 5 will drive the semi-circular clamp 7 to clamp and fix the drainage tube of the catheter body 17. The patient does not need to worry about the drainage tube affecting movement due to shaking or swinging during walking, nor does he / she need to worry about the embarrassment and inconvenience caused by the lack of a suitable storage method. When it is necessary to remove it, the connecting plate 5 can be moved by grasping the extension block 6, so that the connecting plate 5 squeezes the return spring 4 and moves the semi-circular clamp 7 away from the drainage tube. The operation is simple and convenient, and it is easy to use.
