Description

Technical Field

[0001] This invention relates to the field of urological disease technology, and more specifically to a urethral irrigation device for urological diseases. Background Technology

[0002] Most urinary tract diseases are treated by flushing the urethra to resolve urethral infections and remove obstructions such as blood clots or deposits. Inadequate flushing can result from uneven saline injection or the urethral irrigator falling off and causing infection. When performing urethral irrigation on patients with urinary tract diseases, some medical staff need to manually inject saline solution into the patient's urethra. The existing disposable urethral irrigation devices mostly inject saline solution into the urethra by manually controlling the injection speed. However, manual injection of saline solution cannot accurately control the flow rate. At the same time, some inexperienced medical staff may apply too much force when injecting saline solution initially, causing mechanical damage to the urethral wall, resulting in pain and tissue damage. Furthermore, some medical staff cannot control the force applied by hand when manually injecting saline solution, which leads to uneven injection speed and urethral pressure fluctuations, causing uneven pain. Secondly, existing disposable urethral irrigators are all sterile, single-use products. During use, medical staff may slip, become unfamiliar with the procedure, or perform urethral irrigation on individuals without legal capacity, resulting in improper irrigation steps, body positioning, or limb contact. These factors can cause the urethral irrigator to fall to the ground, leading to bacterial infection of the inserted components and rendering the urethral irrigator unusable. This necessitates reassembling the urethral irrigator from scratch, further consuming medical resources and increasing the time required of medical staff. Summary of the Invention

[0003] The purpose of this application is to solve or at least alleviate the problems existing in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a urethral irrigation device for urinary diseases, comprising a retractable bottle body, a nozzle threadedly connected to the upper end of the retractable bottle body, and a spring retractable sleeve fitted on the outer surface of the nozzle body; The outer wall of the retractable bottle is fitted with a speed control and buffer mechanism, wherein: The speed control buffer mechanism includes a tool for rotating a hexagonal slotted plate to adjust the gap between multiple triangular plates. The outer surface of the spring return sleeve is provided with an anti-fouling return mechanism, wherein: The anti-fouling retraction mechanism includes a telescopic link for retracting the retraction sleeve of the pressing spring.

[0005] Optionally, the speed control buffer mechanism further includes a positioning frame, which is sleeved on the outer surfaces of the upper and lower ends of the retractable bottle body. A bent rod is fixedly connected to both outer surfaces of the upper end of the positioning frame, and an adjustment chamber is rotatably connected to the lower end face of the upper part of the bent rod. A rubber sealing ring is slidably connected to the inner surface of the adjustment chamber.

[0006] Optionally, the speed control buffer mechanism further includes a guide groove plate, which is uniformly and equidistantly fixedly connected to the upper end face of the rubber sealing ring. Triangular plates are slidably connected inside the guide groove plate, and the lower ends of the triangular plates are slidably connected to the hexagonal groove plate. A push rod is fixedly connected to the edge of the lower end face of the rubber sealing ring.

[0007] Optionally, the hexagonal groove plate is rotatably connected to the inner surface of the rubber sealing ring, the triangular plates are mutually sealed and slidingly connected, the inner surface of the adjustment chamber is provided with a limiting groove, one side of the extended end of the rubber sealing ring is slidably connected in the limiting groove, the lower end of the adjustment chamber is fixedly connected with a rubber sealing nozzle, and the lower end of the rubber sealing nozzle is slidably connected to the outer surface of the push rod.

[0008] Optionally, the anti-fouling retraction mechanism further includes a support rod, which is fixedly connected to the upper outer surface of the positioning frame. An assist cross rod is rotatably connected to the upper end of the support rod, and a telescopic connecting rod is rotatably connected to the upper end of the assist cross rod. A positioning plate is rotatably connected to the upper end of the telescopic connecting rod.

[0009] Optionally, the anti-fouling retraction mechanism further includes a herringbone hand support plate, the upper end of which is rotatably connected to the lower end hinge of the telescopic connecting rod, and the left and right sides of the herringbone hand support plate are slidably connected to the outer surface of the bent rod. Each of the lower end faces of the herringbone hand support plate is fixedly connected to an assist spring, and the assist springs are all sleeved on the outer surface of the bent rod.

[0010] Optionally, a flexible plastic ring is fixedly connected to the side wall of the positioning plate near the spring retraction sleeve, and the inner diameter of the flexible plastic ring is sleeved on the outer wall of the upper end of the spring retraction sleeve.

[0011] Optionally, the arcuate parts on both sides of the herringbone hand rest are made of hard rubber, and the two sides of the herringbone hand rest are for applying force with the fingers.

[0012] Compared with the prior art, the beneficial effects of the present invention are: The push rod pushes the piston, which is composed of a rubber sealing ring, a guide groove plate, a triangular plate, and a hexagonal groove plate, to move upward from the bottom in the regulating chamber. The pressure applied when the piston moves upward is transmitted to the other side through the hole. If the hole is small, the pressure is transmitted slowly and the piston moves slowly. When the hole is large, the pressure is transmitted quickly and the piston moves faster, thus adjusting the balance of flushing pressure. The size of the circular hole created between the triangular plates determines the resistance to fluid flow. A small hole increases fluid resistance and hinders piston movement, while a large hole reduces resistance, allowing the piston to move faster and facilitating pressure balance adjustment. The pressure temporarily applied to the piston is transmitted to the other side through the hole. If the hole is small, the pressure is transmitted slowly, slowing piston movement; if the hole is large, the pressure is transmitted quickly, accelerating piston movement. By adjusting the size of the hole, the speed at which the piston moves within the regulating chamber is controlled, thus controlling the speed at which medical staff squeeze the retractable bottle. This solves the problem of some inexperienced medical staff initially applying too much force to squeeze the retractable bottle, causing the saline solution inside to spray out rapidly. The pressure of this spray can be irritating to the patient, causing psychological stress. This prevents rapid spraying from causing mechanical damage to the urethral wall, resulting in pain and tissue damage, and also reduces the risk of bacteria entering the urethra and increasing the risk of urinary tract infections. If a urethral irrigator is dropped due to improper handling by medical staff, or if a patient with no legal capacity experiences discomfort while rinsing their urethra, changes in patient position, or physical contact may cause the irrigator to fall, the spring-loaded sleeve will automatically return to its original position. Upon returning to its original position, the spring-loaded sleeve will quickly and automatically cover the nozzle completely during the fall, thus preventing contamination upon impact with the ground and rendering the irrigator unusable. This also avoids the need to use a new urethral irrigator after it falls to the ground, reducing resource waste.

[0013] When not in use, the pressure on the V-shaped support plate is released by hand, and the spring returns the entire spring return sleeve to its original state. This allows the nozzle to be promptly covered after the patient's urethra is flushed, preventing the nozzle from being contaminated with the patient's urethral infection material and dripping into the external environment, thus avoiding environmental pollution. No additional handling of dripping liquid is required, improving the cleanliness and hygiene of using the urethral flushing device. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] refer to Figure 1 The illustration shows a urethral irrigation device for urinary diseases according to an embodiment of the present invention.

[0018] A urethral irrigation device for urinary diseases according to an embodiment of the present invention includes: a retractable bottle body 1, a nozzle 2 threadedly connected to the upper end of the retractable bottle body 1, and a spring retractable sleeve 3 sleeved on the outer surface of the nozzle 2; The outer wall of the retractable bottle body 1 is fitted with a speed control and buffer mechanism, wherein: The speed control buffer mechanism includes a hexagonal groove plate 407 for rotating and adjusting the gap between the holes of multiple triangular plates 406; The outer surface of the spring return sleeve 3 is equipped with an anti-fouling return mechanism, wherein: The anti-fouling retraction mechanism includes a telescopic link 503 for retracting the retraction sleeve 3 of the pressing spring.

[0019] In some embodiments, the speed control buffer mechanism further includes a positioning frame 401, which is sleeved on the outer surfaces of the upper and lower ends of the retractable bottle body 1. A bent rod 402 is fixedly connected to both outer surfaces of the upper end of the positioning frame 401. An adjustment chamber 403 is rotatably connected to the upper and lower end faces of the bent rod 402. A rubber sealing ring 404 is slidably connected to the inner surface of the adjustment chamber 403. The guide groove plate 405 is evenly and equidistantly fixedly connected to the upper end face of the rubber sealing ring 404. Triangular plates 406 are slidably connected inside the guide groove plate 405. The lower end of the triangular plates 406 is slidably connected inside the hexagonal groove plate 407. A push rod 408 is fixedly connected to the edge of the lower end face of the rubber sealing ring 404. The hexagonal groove plate 407 is rotatably connected to the inner surface of the rubber sealing ring 404. The triangular plates 406 are mutually sealed and slidingly connected. The inner surface of the adjusting chamber 403 is provided with a limiting groove 409. One side of the extended end of the rubber sealing ring 404 is slidably connected in the limiting groove 409. The lower end of the adjusting chamber 403 is fixedly connected to a rubber sealing nozzle 410, and the lower end of the rubber sealing nozzle 410 is slidably connected to the outer surface of the push rod 408.

[0020] refer to Figure 7 , Figure 8 , Figure 9 As shown, in the technical solution of this application, considering that the existing urethral irrigators lack speed control and buffering functions, some intern medical staff, lacking operational skills, may inject saline solution into the urethra quickly or at varying speeds. Rapid injection of saline solution causes a rapid increase in urethral pressure, resulting in pain and uneven flow rate. Subsequent slow injection may exacerbate the existing unevenness. Rapid injection can lead to mechanical damage to the urethral wall, while slow injection can cause the liquid to remain in the urethra for too long, increasing the risk of local irritation and inflammation. To address these issues, this technical solution uses a rotating regulating chamber 403 to rotate the hexagonal groove plate 407, offsetting multiple triangular plates 406 to create a gap. The size of this gap can be adjusted to control the flow rate of damping water within the regulating chamber 403 through the triangular plates 406 and the rubber sealing ring 404. This flow rate depends on the speed at which the rubber sealing ring 404 moves from the bottom to the top of the regulating chamber 403, thereby controlling the speed at which the saline solution is discharged from the retractable bottle 1.

[0021] In some embodiments, the anti-fouling retraction mechanism further includes a support rod 501, which is fixedly connected to the upper outer surface of the positioning frame 401. An assisting cross rod 502 is rotatably connected to the upper end of the support rod 501, and a telescopic connecting rod 503 is rotatably connected to the upper end of the assisting cross rod 502. A positioning plate 504 is rotatably connected to the upper end of the telescopic connecting rod 503.

[0022] The anti-fouling retraction mechanism also includes a herringbone support plate 506. The upper end of the herringbone support plate 506 is rotatably connected to the lower end of the telescopic connecting rod 503 at the hinge. The left and right sides of the herringbone support plate 506 are slidably connected to the outer surface of the bent rod 402. The lower end face of the herringbone support plate 506 is fixedly connected to a booster spring 507. The booster spring 507 is sleeved on the outer surface of the bent rod 402. A flexible plastic ring 505 is fixedly connected to one side wall of the positioning plate 504 near the spring retraction sleeve 3. The inner diameter of the flexible plastic ring 505 is sleeved on the upper outer wall of the spring retraction sleeve 3. The curved sides of the herringbone hand rest 506 are made of hard rubber, and the sides of the herringbone hand rest 506 are for the fingers to apply force.

[0023] refer to Figure 3 , Figure 6 As shown, in the technical solution of this application, considering that in the prior art, some medical staff may accidentally drop the urethral cleaning device while holding it, or that persons without civil capacity may experience discomfort during urethral cleaning and move their body or touch it, which may cause the entire urethral cleaning device to fall to the ground, inevitably contaminating the nozzle 2 inserted into the urethra. In order to reduce resource waste and considering the above problems, this technical solution uses the finger to pull the V-shaped hand support plate 506 to pull the telescopic link 503 downward and fold it. During this retraction and folding process, the spring return sleeve 3 will be pressed down and contracted to expose the nozzle 2. When it falls, the finger no longer presses the V-shaped hand support plate 506, the telescopic link 503 will spring back to its original state, and the spring return sleeve 3 will also quickly spring back to completely cover the nozzle 2.

[0024] Preferably, the spring retraction sleeve 3 is designed in the shape of a bellows, with the inner diameter of the lower end being the same as the outer diameter of the lower end of the nozzle 2. The spring retraction sleeve 3 has a built-in spring that helps to rebound. When pressed downward by the telescopic link 503, it retracts downward and automatically rebounds to quickly protect the nozzle 2 after the downward pressing ends.

[0025] General working principle: Assembly steps: refer to Figure 10 As shown, first open the outer packaging bag of the disposable urethral irrigator, pinch the nozzle 2 from the outer surface of the packaging bag, and slowly push the nozzle 2 out of the packaging bag towards the end that sprays water. After the nozzle 2 is pushed out a part, align the spring retraction sleeve 3 with the exposed end, and then continue to push the nozzle 2 out completely into the spring retraction sleeve 3, so that the arc provided at the lower upper part of the nozzle 2 fits with the rubber part at the lower end of the spring retraction sleeve 3. It can be seen that the lower end of the spring retraction sleeve 3 is made of hard rubber material. Push the spring retraction sleeve 3 with force so that the lower end is squeezed and fitted onto the arc provided at the lower upper part of the nozzle 2 to form a fixed state. Then, pinch the retractable bottle 1 to flatten it, and tilt the retractable bottle 1 so that its upper end is inserted into the upper ring of the positioning frame 401. Finally, rotate the tilted retractable bottle 1 around the upper ring of the positioning frame 401 to make it vertical. Release the pinch on the retractable bottle 1, and the retractable bottle 1 will spring back and abut against the arcs at the upper and lower ends of the positioning frame 401. After the operation is completed, thread the nozzle 2 with the spring retractable sleeve 3 onto the opening on the retractable bottle 1. Then, bend the vertically positioned flexible plastic ring 505 into a horizontal position, and place the flexible plastic ring 505 in a ring shape at the upper end of the spring retractable sleeve 3. After the above steps are completed, the assembly step is finished.

[0026] Adjustment steps: Resistance adjustment refer to Figure 7 , Figure 8 , Figure 9 , Figure 5 As shown, medical staff first rotate the adjustment chamber 403 according to the positions on its outer wall. During the rotation of the adjustment chamber 403, the hexagonal groove plate 407 is simultaneously driven to rotate within the rubber sealing ring 404 through the limiting groove 409. During the rotation of the hexagonal groove plate 407, the hexagonal groove on its upper surface presses against the triangular plates 406 located in the six straight grooves of the hexagonal groove opening. At this time, the rotation of the hexagonal groove plate 407 causes one end of each straight groove in the hexagonal groove to be displaced and raised. The raised end presses against the sliding rod at the upper end of the triangular plate 406, which slides along the outer end of the guide groove plate 405. As multiple triangular plates 406 slide along the outer end of the guide groove plate 405... At this time, multiple triangular plates 406 are staggered to form a circular hole in the middle. The larger the rotation range of the hexagonal groove plate 407, the larger the circular hole formed between the multiple triangular plates 406. By adjusting the different sizes of holes formed between the triangular plates 406, the piston composed of the rubber sealing ring 404, guide groove plate 405, triangular plate 406, and hexagonal groove plate 407 is pushed by the push rod 408 to move upward from the bottom in the adjustment chamber 403. The pressure applied when the piston moves upward will be transmitted to the other side through the hole. If the hole speed is small, the pressure is transmitted slowly and the piston moves slowly. When the hole is large, the pressure is transmitted faster and the piston moves faster, thereby adjusting the balance of flushing brine pressure. Advanced Level 1: Rebound prevents infection refer to Figure 2 , Figure 3 , Figure 6As shown, at this time, the medical staff places their index and middle fingers on the upper surfaces of the A-frame support plate 506 on both sides, and presses their thumbs on the bottom of the retractable bottle 1. Holding the urethral cleaning device in this way, the medical staff applies downward pressure with their index and middle fingers. The two sides of the A-frame support plate 506 slide downward on the outer surface of the bent rod 402. While sliding downward, the assist spring 507 is compressed and retracted. The lower end of the telescopic link 503 is pulled downward with the lower hinge point of the telescopic link 503 as the center. At this time, the telescopic link 503 pushes the assist cross rod 502 downward to rotate to both sides. At the same time, it pulls the two sides of the lowest end of the telescopic link 503 to move to the left and right sides respectively, thereby retracting and folding the telescopic link 503 downward. As the telescopic link 503 retracts and folds, it moves downward via the positioning plate 504 and the flexible plastic ring 505 until it is fitted onto the outer surface of the uppermost end of the spring retraction sleeve 3. As the telescopic link 503 continues to move downward, it presses the spring retraction sleeve 3 downward through the flexible plastic ring 505, causing it to retract and fold, and gradually exposing the nozzle 2. Thus, it can be seen that the spring retraction sleeve 3 has a built-in spring. If the urethral irrigator is dropped due to improper handling by medical staff, or if some patients, who are incapacitated, experience discomfort while rinsing their urethra, or if the patient's position changes or their limbs touch the urethral irrigator and it is knocked off, the spring retraction sleeve 3 will spring back to its original state due to the built-in spring. When it springs back to its original state, the spring retraction sleeve 3 will quickly and automatically cover the nozzle 2 completely during the fall, thus preventing contamination upon falling to the ground and rendering the irrigator unusable. It also avoids the need to use a new urethral irrigator after it falls to the ground, thus preventing resource waste. Advanced Level Two: Resistance limits uniform injection refer to Figure 7 , Figure 6 , Figure 3 , Figure 2As shown, after the spring retraction sleeve 3 is pressed down and retracted through the A-frame support plate 506 and the telescopic connecting rod 503 to allow the nozzle 2 to leak out, the index and middle fingers continue to press down on the A-frame support plate 506. This indicates that the force used by the spring retraction sleeve 3 and the assist spring 507 is less than the force required to generate pressure after the saline solution is injected into the retraction bottle 1. With the index and middle fingers pressing down on the A-frame support plate 506, a certain size hole is created between the triangular plates 406 by rotating the adjustment chamber 403 beforehand. At this time, the medical staff apply downward pressure with their index and middle fingers pressing on the A-frame support plate 506. When the thumb, positioned at the bottom of the retractable bottle 1, applies an upward force, and the index, middle, and thumb simultaneously squeeze the retractable bottle 1, the positioning frame 401 at the bottom of the retractable bottle 1 is also pushed, and simultaneously, through the push rod 408, it drives the piston composed of the rubber sealing ring 404, guide plate, triangular plate 406, and hexagonal groove plate 407 (hereinafter referred to as the piston). During the process of the piston moving upward from the bottom in the regulating chamber 403, since the regulating chamber 403 above the upper end of the piston is filled with brine, during the process of the piston moving upward from the bottom of the regulating chamber 403, multiple triangular plates are adjusted. The circular holes created between the triangular plates 406 allow the brine in the upper part of the regulating chamber 403 to flow into the lower end of the regulating chamber 403 of the piston as the piston continues to move upward. The size of the circular holes between the triangular plates 406 determines the resistance to fluid flow. Small holes increase fluid resistance and hinder piston movement, while large holes reduce resistance, allowing the piston to move faster and facilitating pressure balance adjustment. The pressure temporarily applied to the piston is transmitted to the other side through the holes. If the holes are small, the pressure is transmitted slowly, slowing down piston movement. When the pressure increases, the pressure is transmitted faster, and the piston moves faster. By adjusting the size of the orifice, the speed at which the piston moves within the regulating chamber 403 can be controlled. This, in turn, controls the speed at which medical staff squeeze the retractable bottle 1. This solves the problem that some inexperienced medical staff may initially apply too much force to squeeze the retractable bottle 1, causing the saline solution inside the bottle 1 to spray out rapidly. The pressure of this spray can be irritating to the patient, causing psychological stress. At the same time, the rapid spray can cause mechanical damage to the urethral wall, resulting in pain and tissue damage. This reduces the risk of bacteria entering the urethra and lowers the risk of urinary tract infections.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
