Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a visual urinary catheter. Background Art

[0002] A visual urinary catheter is an innovative medical device that combines image guidance technology, enabling medical staff to view the internal structures of the urethra and bladder in real time during the catheterization operation, ensuring the correct and safe insertion of the urinary catheter. Compared with traditional urinary catheters, visual urinary catheters use built-in cameras or external imaging devices to improve the accuracy of the insertion operation and reduce the incidence of complications, especially in patients with complex pathology or anatomical structure abnormalities.

[0003] For example, a Chinese invention patent (CN 119367663 A) discloses a visual urinary catheter kit, which records: "The setting of the corrugated pipe can enhance the hardness of the catheter body, enabling the catheter body to be more accurately introduced. At the same time, a switch component is also provided, so that the lubricating liquid medicine in the first branch pipe can lubricate the urethra during the introduction of the catheter body to reduce the damage to the urethra. When the front end of the catheter body enters the bladder, the first liquid outlet is closed, causing the liquid storage sac to expand to fix the catheter body and prevent the catheter body from falling off." It also records the technical problem: "The soft tube body used has a relatively soft texture. Due to the long urethra and many bends, the soft texture of the soft tube body makes it impossible to accurately control the direction of the soft tube, and the introduction process is difficult, time-consuming and laborious. Moreover, the friction during the introduction process is also likely to cause discomfort to the patient. When changing to a harder tube body, it is easy to damage the inner wall of the urethra."

[0004] In summary, it can be seen that in the prior art, lubricating liquid is injected into the first branch pipe through a first one-way valve. However, this method has the following technical problems: The above setting of the one-way valve can only make the lubricating liquid medicine enter the first branch pipe from the infusion end to prevent the lubricating liquid medicine entering the first branch pipe from flowing back. In fact, when removing the urinary catheter, the lubricating liquid in the liquid storage sac needs to be pumped out to shrink the volume of the liquid storage sac for the convenience of removing the urinary catheter. The above device only sets a first one-way valve, which is inconvenient in the operation of removing the urinary catheter. Therefore, the present application proposes a visual urinary catheter to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the Invention

[0005] Based on this, it is necessary to provide a visual catheter for the above technical problems. By passing the liquid outlet pipe of a syringe filled with physiological saline through the cross opening on the connecting pipe, and then the liquid outlet pipe presses against the blocking ball, separating the blocking ball from the baffle. Subsequently, the medical staff can slightly tilt the liquid outlet pipe to create a certain gap between the liquid outlet on the liquid outlet pipe of the syringe and the blocking ball. Then, the physiological saline in the syringe can be injected into the connecting groove through the connecting pipe, and then into the balloon, causing the balloon to expand. Subsequently, the medical staff can pull out the syringe, and the blocking ball can be tightly attached to the baffle under the elastic force of the first spring, reducing the situation of physiological saline flowing to the outside through the connecting pipe, enabling the front end of the catheter main body to stay in the patient's bladder relying on the inflated balloon, and ensuring the stability of the device installation.

[0019] The visual catheter provided by the present invention enables the liquid outlet tube of a syringe filled with normal saline to pass through the cross-shaped opening on the connecting tube. Subsequently, the liquid outlet tube presses against the blocking ball, separating the blocking ball from the baffle.

After the catheter is inserted properly, medical staff can also observe the images of the patient's bladder on the display screen to check the urine volume and whether there are blood clots in the bladder. Moreover, during the insertion of the catheter body, medical staff can release the restriction between the sliding shell and the limiting rod by pressing the pressing rod. Subsequently, medical staff can drive the camera to adjust its position within the catheter body through the connecting wire, thereby adjusting the focusing distance of the camera to ensure clear captured images. And this process is relatively simple and convenient for medical staff to adjust. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0037] As described in the background art, however, the above-mentioned setting of the one-way valve can only make the lubricating liquid medicine enter the first branch pipe from the infusion end to prevent the reflux of the lubricating liquid medicine entering the first branch pipe. In fact, when removing the urinary catheter, it is necessary to draw out the lubricating liquid in the liquid storage sac to shrink the volume of the liquid storage sac for the convenience of removing the urinary catheter. However, the above device only sets a first one-way valve, which is a bit inconvenient in the operation of removing the urinary catheter.

[0038] To solve this technical problem, the present invention provides a visual urinary catheter, which is applied to medical treatment.

[0039] Specifically, please refer to Figures 1 - 2 , the visual urinary catheter specifically includes:

[0040] A urinary catheter main body 1, a cap 2 is fixedly installed on the outer wall of the urinary catheter main body 1, a sealing rubber 3 is fixedly connected to the inner wall of the cap 2, a connecting wire 4 is slidably connected to the inner wall of the sealing rubber 3, a processor 5 is fixedly connected to the outer wall of the connecting wire 4, the processor 5 is electrically connected to a display screen 6, a communication mechanism 7 is arranged on the urinary catheter main body 1, an adjustment mechanism 8 is arranged on the cap 2, one end of the connecting wire 4 located inside the urinary catheter main body 1 is fixedly connected to a camera 9, and a plurality of support plates 10 are fixedly connected to the outer wall of the connecting wire 4, and the plurality of support plates 10 are all slidably connected to the inner wall of the urinary catheter main body 1;

[0041] The communication mechanism 7 includes a connecting pipe 11, a urine outlet pipe 12, a lubricating liquid pipe 13, a limiting component, a blocking component, an expanding component, and a lubricating component. The connecting pipe 11 and the lubricating liquid pipe 13 are fixedly connected to the outer wall of the urinary catheter main body 1, and the urine outlet pipe 12 is fixedly connected to the inner wall of the urinary catheter main body 1.

[0042] The visual catheter provided by the present invention enables the liquid outlet pipe of a syringe filled with physiological saline to pass through the cross-shaped opening 20 on the connecting pipe 11. Subsequently, the liquid outlet pipe presses against the blocking ball 18, separating the blocking ball 18 from the baffle 15. Then, the medical staff can slightly tilt the liquid outlet pipe to create a certain gap between the liquid outlet of the liquid outlet pipe of the syringe and the blocking ball 18. Subsequently, the physiological saline in the syringe can be injected into the connecting groove 21 through the connecting pipe 11 and then into the balloon 22, causing the balloon 22 to expand. Then, the medical staff can pull out the syringe, and under the elastic force of the first spring 17, the blocking ball 18 will closely adhere to the baffle 15, reducing the situation where the physiological saline flows to the outside through the connecting pipe 11, enabling the front end of the catheter body 1 to remain in the patient's bladder relying on the inflated balloon 22 and ensuring the stability of the device installation.

[0043] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0044] Embodiment 1:

[0045] Please refer to Figures 1 - 8 , a visual catheter, which includes:

[0046] The catheter main body 1 is fixedly installed with a cap 2 on the outer wall thereof. The inner wall of the cap 2 is fixedly connected with a sealing rubber 3. The inner wall of the sealing rubber 3 is slidably connected with a connecting wire 4. The outer wall of the connecting wire 4 is fixedly connected with a processor 5. The processor 5 is electrically connected to a display screen 6. A communication mechanism 7 is arranged on the catheter main body 1. An adjustment mechanism 8 is arranged on the cap 2. One end of the connecting wire 4 located inside the catheter main body 1 is fixedly connected with a camera 9. The outer wall of the connecting wire 4 is fixedly connected with a plurality of support plates 10. The plurality of support plates 10 are all slidably connected to the inner wall of the catheter main body 1. By supporting the camera 9 through the plurality of support plates 10, the distances between the outer wall of the camera 9 and the inner wall of the catheter main body 1 at various positions around can be made the same, so as to facilitate the urine to flow into the catheter main body 1, and also facilitate the operator to relatively accurately know the position where the catheter main body 1 is located through the video captured by the camera 9. Among them, the number of the support plates 10 is two, three or four. The sealing rubber 3 has a certain elasticity and closely adheres to the outside of the connecting wire 4, which can prevent the urine in the catheter main body 1 from flowing out through the gap between the sealing rubber 3 and the connecting wire 4. It should be noted that in this application, the camera 9 is a micro camera, and the specific size can be adjusted according to requirements. These micro cameras are usually of high definition (HD) or full high definition (FHD) level, and can provide clear images under limited light conditions to help doctors observe the urethra and bladder conditions in real time. At the same time, since the inside of the catheter main body 1 is usually insufficient in light, the micro camera is equipped with an LED or fiber optic light source, which can illuminate the internal environment of the catheter main body 1 to ensure sufficient lighting for imaging. The micro camera transmits the video data to the processor 5 through the adapted connecting wire 4 for processing. Subsequently, the processor 5 transmits the processed image signal to the display screen 6 through a cable, and the doctor can view the urethra and bladder in real time;

[0047] The communication mechanism 7 includes a connecting pipe 11, an outlet urine pipe 12, a lubricating fluid pipe 13, a limiting component, a blocking component, an expanding component, and a lubricating component. The outer wall of the catheter main body 1 is fixedly connected with a connecting pipe 11 and a lubricating fluid pipe 13. The inner wall of the catheter main body 1 is fixedly connected with an outlet urine pipe 12. One end of the outlet urine pipe 12 far away from the catheter main body 1 is connected with a urine bag through a hose. This part belongs to the prior art and will not be specifically described here. By injecting normal saline into the connecting pipe 11, the balloon 22 can be correspondingly inflated, so that the catheter main body 1 can be stuck in the patient's bladder. By injecting lubricating fluid into the lubricating fluid pipe 13, it is convenient for medical staff to insert the catheter main body 1.

[0048] The limiting component includes a fixing frame 14. The inner walls of the connecting pipe 11, the urine outlet pipe 12, and the lubricating fluid pipe 13 are respectively fixedly connected to the fixing frame 14. The inner walls of the three fixing frames 14 are all slidably connected to a T-shaped rod 16. A first spring 17 is sleeved on the outer part of each of the three T-shaped rods 16. The first spring 17 is fixedly connected to the outer wall of the fixing frame 14. Baffles 15 are respectively fixedly connected to the inner walls of the connecting pipe 11, the urine outlet pipe 12, and the lubricating fluid pipe 13. A blocking ball 18 adapted to the baffle 15 is fixedly connected to the outer wall of the T-shaped rod 16. One end of the first spring 17 away from the fixing frame 14 is fixedly connected to the outer wall of the blocking ball 18. The limiting components in the connecting pipe 11 and the lubricating fluid pipe 13 can respectively allow normal saline and lubricating fluid to be injected into the connecting pipe 11 and the lubricating fluid pipe 13. At the same time, it is also possible to draw out the normal saline in the balloon 22 by inserting a syringe into the connecting pipe 11, which restricts the reverse flow of normal saline or lubricating fluid when the syringe is not inserted into the connecting pipe 11 or the lubricating fluid pipe 13. The limiting component in the urine outlet pipe 12 allows the urine in the patient's bladder to flow through the catheter main body 1 and the urine outlet pipe 12 to the urine bag, and restricts the reverse flow of the urine in the urine bag into the catheter main body 1.

[0049] The blocking component includes a rubber disc 19. The rubber discs 19 are respectively fixedly connected to the inner walls of the connecting pipe 11 and the lubricating fluid pipe 13. Cross-shaped openings 20 are provided on the outer walls of the two rubber discs 19 and close to the center. The blocking component reduces the situation that when the device is worn on the patient, non-medical staff accidentally squeeze the blocking ball 18, resulting in the outflow of normal saline or urine through the connecting pipe 11 or the lubricating fluid pipe 13. When the liquid outlet pipe of the syringe passes through the cross-shaped opening 20, the cross-shaped opening 20 will expand accordingly. Due to the certain elasticity of the rubber disc 19 itself, the rubber disc 19 will closely fit on the liquid outlet pipe of the syringe, reducing the reverse outflow of the liquid in the patient's body or the injected liquid.

[0050] The expanding component includes a connecting groove 21. The connecting groove 21 is provided on the inner wall of the catheter main body 1. A balloon 22 is fixedly connected to the outer wall of the catheter main body 1. The two ends of the connecting groove 21 are respectively communicated with the connecting pipe 11 and the balloon 22. The expansion of the balloon 22 can stably fix the catheter main body 1 in the patient's bladder, improving the stability of the device placement.

[0051] The lubrication assembly includes a lubricating fluid tank 23. A lubricating fluid tank 23 is provided in the catheter body 1. An annular groove 24 is provided in the catheter body 1. The two ends of the lubricating fluid tank 23 are respectively communicated with the annular groove 24 and the lubricating fluid pipe 13. A plurality of outlet grooves 25 communicated with the annular groove 24 are provided in the catheter body 1. The outlet grooves 25 are communicated with the outside. It should be noted that the catheter body 1 in the prior art is coated with a lubricating layer before being inserted into the urethra. However, this lubricating layer gradually becomes thinner until it can no longer play a lubricating role as the catheter body 1 is gradually inserted. Since, during the insertion of the catheter body 1, the front end of the catheter body 1 continuously contacts the inner wall of the urethra that has not been contacted before, the lubricating layer at the front end of the original catheter body 1 becomes relatively thin quickly. And the inside of the urethra contacted by the front end of the catheter body 1 will be contaminated with some lubricating fluid, thereby relatively reducing the consumption of the lubricating fluid on the part outside the catheter body 1 and away from the front end of the catheter body 1. In this embodiment, the final flow of the lubricating fluid is through the outlet grooves 25 provided at the front end of the catheter body 1. The lubricating fluid flowing out will preferentially replenish the front end of the catheter body 1, making up for the rapid consumption of the lubricating layer at the front end of the catheter body 1, and thus making the insertion process of the catheter body 1 smoother.

[0052] With the above structural design, when medical staff need to insert the catheter main body 1 into a patient, the urine bag can be first connected to the urine outlet tube 12, and then the catheter main body 1 is inserted into the patient's urethra. During this process, the camera 9 can collect video data on the internal situation of the patient's urethra, and then the collected data is transmitted to the processor 5 through the connection line 4. Subsequently, the processor 5 converts these data into images that can be presented on the display screen 6. Medical staff can observe whether there is urethral rupture and stenosis during the catheterization process according to the images displayed on the display screen 6, and at the same time assist the patient in inserting the catheter main body 1. During the insertion process, when it is necessary to inject lubricating fluid, the liquid outlet tube of the syringe filled with lubricating fluid is passed through the cross opening 20 on the lubricating fluid tube 13, and then the liquid outlet tube presses against the blocking ball 18, causing the blocking ball 18 to separate from the baffle plate 15. During this process, the T-shaped rod 16 slides on the inner wall of the fixing frame 14, and the first spring 17 deforms accordingly. Subsequently, the medical staff can slightly tilt the liquid outlet tube so that there is a certain gap between the liquid outlet of the liquid outlet tube of the syringe and the blocking ball 18. Then, the lubricating fluid in the syringe can be injected into the lubricating fluid tank 23 through the lubricating fluid tube 13. Subsequently, the lubricating fluid fills the annular groove 24, and finally the lubricating fluid flows into the urethra through each outlet groove 25. After the lubricating fluid injection is completed, the medical staff can remove the syringe, and then the blocking ball 18 can be made to closely adhere to the baffle plate 15 under the action of the elastic force of the first spring 17. When the front end of the catheter main body 1 is inserted into a suitable position in the patient's urethra, the medical staff inserts a syringe filled with normal saline into the urine outlet tube 12, and then performs an operation similar to the lubricating fluid injection principle to inject the normal saline into the balloon 22 through the connection groove 21. Subsequently, the balloon 22 expands in the patient's bladder, thereby restricting the position of the catheter main body 1. When the medical staff needs to remove the catheter main body 1 from the patient's body, the medical staff inserts an empty syringe into the cross opening 20 on the urine outlet tube 12, and makes the liquid outlet tube of the syringe press against the blocking ball 18, and pushes the blocking ball 18 away from the baffle plate 15 through the syringe and its liquid outlet tube. Then, the extraction operation is performed by relying on the syringe, and the normal saline in the balloon 22 can be extracted through the connection groove 21, thereby reducing the volume of the balloon 22 in preparation for removing the catheter main body 1. Subsequently, the operation of removing the catheter main body 1 can be carried out.

[0053] Embodiment 2:

[0054] The visual catheter provided in Embodiment 1 is further optimized. Specifically, as Figures 9 - 11As shown in the figure, the adjusting mechanism 8 includes a limiting rod 26, a sliding shell 27, a pressing component, and a clamping component. Two limiting rods 26 are fixedly connected to the outer wall of the cap 2, and a sliding shell 27 is fixedly connected to the outer wall of the connecting line 4. The sliding shell 27 is slidably connected to the outer walls of the two limiting rods 26. The adjusting mechanism 8 can adjust the position of the camera 9 in the catheter main body 1 and adjust the focusing distance of the camera 9, so as to ensure that the captured image is clear.

[0055] The pressing component includes a pressing rod 28. The pressing rod 28 is slidably connected to the inner wall of the sliding shell 27. A sliding plate 29 is fixedly connected to the outer wall of the pressing rod 28. A second spring 30 is sleeved outside the pressing rod 28. The two ends of the second spring 30 are respectively fixedly connected to the outer wall of the sliding plate 29 and the inner wall of the sliding shell 27. Through the pressing component, the restriction between the sliding shell 27 and the limiting rod 26 can be released, and this process is relatively simple to operate.

[0056] The clamping component includes a rotating rod 31. Two rotating rods 31 are rotatably connected to the inner wall of the sliding shell 27. Clamping plates 32 are respectively fixedly connected to the outer walls of the two rotating rods 31. The two clamping plates 32 are respectively slidably connected to the front and back sides of the pressing rod 28. The clamping plates 32 are movably clamped outside the limiting rod 26. The clamping component can limit the sliding shell 27 outside the limiting rod 26, and further limit the position of the camera 9 inside the catheter main body 1, ensuring the stability of obtaining the image information of the patient's body.

[0057] Through the above structural design, during the insertion of the catheter main body 1, medical staff can press the pressing rod 28 to drive the sliding plate 29 to move accordingly, causing the second spring 30 to deform accordingly, and then squeezing the two clamping plates 32, so that the two clamping plates 32 respectively rotate around the corresponding rotating rods 31, causing the clamping plates 32 to leave the corresponding limiting rods 26 and releasing the restriction between the sliding shell 27 and the limiting rod 26. Then, medical staff can move the sliding shell 27, and the connecting line 4 drives the camera 9 to adjust its position inside the catheter main body 1, so as to adjust the focusing distance of the camera 9. After adjusting the camera 9 to the appropriate position, the medical staff can release the pressing rod 28. Then, the pressing rod 28 slides inside the sliding shell 27 under the action of the elastic force of the second spring 30, driving the two clamping plates 32 to rotate in cooperation with the corresponding rotating rods 31, causing the clamping plates 32 to be clamped inside the corresponding limiting rods 26, and then the position of the sliding shell 27 can be restricted.
