Description

Technical Field

[0001] This utility model relates to the field of urinary catheter fixation technology, and in particular to a novel urinary catheter. Background Technology

[0002] A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. It is made of natural rubber, silicone rubber, or polyvinyl chloride. After the catheter is inserted into the bladder, a balloon near the tip of the catheter secures it in the bladder, preventing it from easily falling out. The drainage tube is connected to a urine bag to collect urine. In current technology, common urinary catheters lack fixation and may wobble during use.

[0003] Existing patent (publication number: CN221731789U) discloses "This utility model relates to the field of urinary catheters, and discloses a novel anti-dislodgement urinary catheter, including a catheter body, an air balloon fixedly connected to the outer wall of the catheter body, a drainage head fixedly connected to the bottom of the catheter body, a fixing tube fixedly connected to the top of the catheter body, a shunt tube fixedly connected to the top of the fixing tube, a fixing connector fixedly connected to the top of the shunt tube, a one-way air valve fixedly connected to the right side of the shunt tube, a fixing component provided on the outer wall of the fixing tube, and a urine bag provided on the outer side of the air balloon, the interior of the urine bag communicating with the interior of the catheter body. In this utility model, by fixing the left fixing plate to the fixing tube, flipping the fixing plate with an opening and closing plate to press the fixing buckles on both sides into the through hole for fixing, and fixing the Velcro on both sides to the position where fixing is needed, the urinary catheter can be fixed, achieving a firm fixation effect and preventing dislodgement."

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: When using this catheter, although the fixing plates on both sides can be pressed into the through holes by flipping the opening and closing plate to fix it, and the Velcro on both sides can be fixed in the position that needs to be fixed, thus completing the fixing of the catheter, the opening and closing plate and the catheter are fixed together and cannot be disassembled. Some users may experience a foreign body sensation when using it.

[0005] Therefore, this application provides a novel urinary catheter to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel urinary catheter. When using this urinary catheter, the fixing mechanism can be installed or disassembled according to the actual situation, thereby improving the practicality of the urinary catheter.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a novel urinary catheter, comprising a fixing mechanism, an outer tube wall, a water bladder, an external air bladder, and an inner tube wall. The fixing mechanism comprises a first fixing frame, a second fixing frame, and a third fixing frame. The second fixing frame has four fixing buckles fixedly installed on the side near the third fixing frame, and the third fixing frame has four fixing grooves on the side near the second fixing frame.

[0008] A storage frame is fixedly installed on the side of the third fixing frame away from the second fixing frame. Sliding grooves are provided on the upper and lower sides of both the second and third fixing frames. An installation plate is slidably snapped onto the side of the second fixing frame away from the third fixing frame.

[0009] Furthermore, the inner tube wall is disposed inside the outer tube wall, and the first fixing bracket is fixedly disposed around the outer tube wall.

[0010] Furthermore, a fixing airbag is provided around the lower end of the outer tube wall, and an inner tube body is provided inside the inner tube wall.

[0011] Furthermore, a fixing block is fixedly provided on one side of the mounting plate, and Velcro is fixedly provided on the surface of the mounting plate.

[0012] Furthermore, the water bladder is disposed on one side of the upper end of the outer tube wall, and the external air bladder is disposed on one side of the upper end of the outer tube wall.

[0013] Furthermore, the inner tube body is connected to the fixed airbag.

[0014] Furthermore, the outer airbag is connected to the interlayer between the outer tube wall and the inner tube wall.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a novel urinary catheter. When in use, a fixing balloon is inserted into the user's body, and water is injected into the balloon. The water is then transported through the inner tube body to the fixing balloon, causing it to expand. This helps to fix the urinary catheter in the user's body. Air is then injected into the gap between the outer tube wall and the inner tube wall through the outer balloon, which helps to expand the outer tube wall. This allows the catheter to be increased in size and fixed according to the user's physical condition, thus improving its practicality.

[0017] 2. The present invention proposes a novel urinary catheter. When in use, the catheter can be fixed to the surface of the user's clothing by the Velcro on the surface of the mounting plate, thereby fixing the catheter, improving stability and preventing shaking. When the catheter does not need to be fixed, the second and third fixing brackets can be pulled to disengage the fixing buckle from the fixing groove, thereby completing the disassembly of the fixing mechanism. This allows the user to freely choose to install or disassemble the fixing mechanism according to their needs. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 An embodiment of this utility model provides a novel urinary catheter, comprising a fixing mechanism 1, an outer tube wall 2, a water-filled balloon 4, an external air balloon 5, and an inner tube wall 7. The inner tube wall 7 is disposed inside the outer tube wall 2. A first fixing frame 104 is fixedly disposed around the outer tube wall 2. A fixing air balloon 3 is disposed around the lower end of the outer tube wall 2. An inner tube body 6 is disposed inside the inner tube wall 7. The water-filled balloon 4 is disposed on one side of the upper end of the outer tube wall 2. The external air balloon 5 is disposed on one side of the upper end of the outer tube wall 2. The inner tube body 6 is connected to the fixing air balloon 3. The external air balloon 5 is connected to the interlayer between the outer tube wall 2 and the inner tube wall 7.

[0027] Specifically, the fixing balloon 3 is inserted into the user's body, and then water is injected into the water balloon 4. The water then flows through the inner tube body 6 to the fixing balloon 3, causing it to inflate and thus fixing the urinary catheter in the user's body to prevent it from falling out. Air is injected into the gap between the outer tube wall 2 and the inner tube wall 7 through the outer balloon 5, causing it to inflate. This allows for free adjustment of the catheter's diameter according to the user's actual situation, and the catheter can be enlarged and fixed at any time according to the patient's physical condition, further improving the practicality of the urinary catheter.

[0028] Reference Figure 4 and Figure 5 The fixing mechanism 1 includes a first fixing frame 104, a second fixing frame 105, and a third fixing frame 107. The second fixing frame 105 is fixedly provided with four fixing buckles 108 on the side close to the third fixing frame 107. The third fixing frame 107 is provided with four fixing slots 106 on the side close to the second fixing frame 105. The third fixing frame 107 is fixedly provided with a storage frame 103 on the side away from the second fixing frame 105. The second fixing frame 105 and the third fixing frame 107 are provided with sliding grooves on their upper and lower sides. The second fixing frame 105 is slidably snapped onto the side away from the third fixing frame 107. A fixing block 102 is fixedly provided on one side of the mounting plate 101. Velcro is fixedly provided on the surface of the mounting plate 101.

[0029] Specifically, the fastening mechanism 1 is fixed to the user's clothing surface by the Velcro on the surface of the mounting plate 101, which helps to prevent the catheter from shaking and loosening, thus improving stability. When the user does not need to fix the catheter, they can push the fixing block 102 to slide the mounting plate 101 into the storage frame 103, thus not limiting the catheter. In addition, the second fixing bracket 105 and the third fixing bracket 107 can be pulled at the same time, causing the four fixing buckles 108 to disengage from the four fixing slots 106, which helps to disengage the second fixing bracket 105 and the third fixing bracket 107 from the first fixing bracket 104, thus completing the disassembly of the fastening mechanism 1. This helps to reduce the weight of the catheter and improve comfort. The user can freely install and remove the fastening mechanism 1 according to their needs, further improving the practicality of the catheter.

[0030] Working principle: When using this catheter, water is injected into the water bladder 4 and then delivered to the fixing air bladder 3 through the inner tube body 6, causing it to expand and thus securing the catheter to the user's body. After securing, air can be introduced into the gap between the outer tube wall 2 and the inner tube wall 7 through the outer air bladder 5, causing it to expand. This allows for adjustment of the thickness of the outer tube wall 2 according to the user's actual situation, preventing it from falling off during use. After securing the fixing air bladder 3 to the user's body, the catheter can also be secured by the Velcro on the surface of the mounting plate 101 to prevent shaking. When the user does not need to secure the outer tube wall 2, they can choose to push the fixing block 102 to slide the mounting plate 101 into the storage frame 103, or simultaneously pull the second fixing bracket 105 and the third fixing bracket 107 to move away from each other, causing the four fixing buckles 108 to disengage from the fixing groove 106, thereby disengaging the second fixing bracket 105 and the third fixing bracket 107 from the first fixing bracket 104. This allows the user to freely choose to install or disassemble the fixing mechanism 1 according to the actual situation.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
