Abstract
Description
Technical Field
[0001] This utility model relates to irrigation equipment, specifically a bladder irrigation device for urology. Background Technology
[0002] In clinical treatment of urological diseases, bladder irrigation is an extremely important procedure. Bladder irrigation involves instilling a specific solution into the bladder through a catheter, followed by drainage using the siphon principle. This process aims to cleanse the bladder, prevent or control infection, and remove residual substances from the bladder, playing a crucial auxiliary role in the treatment of urethral diseases.
[0003] However, current bladder irrigation devices on the market have many problems that urgently need to be addressed. One of the most prominent issues is the lack of an automatic throttling mechanism. During actual bladder irrigation, healthcare professionals need to constantly monitor the remaining irrigation fluid to ensure the irrigation operation is stopped promptly when the fluid is almost depleted. However, clinical work is often busy and complex, making it difficult for healthcare professionals to maintain precise monitoring at all times. If negligence occurs, air can easily enter the bladder through the catheter after the irrigation fluid is used up. Air entering the bladder can lead to a series of adverse consequences, such as increasing the risk of bladder infection because bacteria and other microorganisms in the air may enter the bladder; it can also cause discomfort symptoms such as bladder spasms and pain, seriously affecting the patient's treatment experience and recovery process. This not only brings additional suffering to the patient and negatively impacts the treatment effect but may even lead to medical disputes. Utility Model Content
[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a bladder irrigation device for urology, which effectively solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model includes:
[0006] The flushing tube has its inlet end connected to the flushing bottle;
[0007] The flushing bottle is equipped with a float ball inside the cavity. A sealing plate is fixedly connected to the bottom of the float ball. The diameter of the sealing plate is larger than the inner diameter of the inlet opening of the flushing tube.
[0008] The top of the connecting column is fixedly connected to the bottom of the sealing plate, and its bottom extends into the flushing pipe and is fixed with a disc.
[0009] The limiting plate is sleeved on the outer periphery of the connecting column and located above the disc. The limiting plate has a through hole in the center for the connecting column to pass through. The limiting plate is fixedly connected to the inner wall of the flushing pipe by at least two symmetrically arranged fixing rods.
[0010] Preferably, the density of the float is less than that of the flushing fluid, and its maximum buoyancy is greater than the total weight of the sealing disc and the connecting column.
[0011] Preferably, the sealing disc is made of medical-grade silicone, and its bottom surface is provided with a conical sealing surface that matches the shape of the inlet opening of the flushing tube.

[0024] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.
[0025] Example 1, by Figure 1-4 This utility model provides a bladder irrigation device for urology, including an irrigation tube 1, an irrigation bottle 2, a strap 3, a float 4, a sealing disc 5, a connecting column 6, a disc 7, a limiting disc 8, a through hole 9, and a fixing rod 10.
[0026] Rinse tube 1, its inlet end is connected to rinse bottle 2;
[0027] The inner cavity of the rinsing bottle 2 is provided with a float 4, and a sealing plate 5 is fixedly connected to the bottom of the float 4. The diameter of the sealing plate 5 is larger than the inner diameter of the liquid inlet opening of the rinsing pipe 1.
[0028] The top of the connecting column 6 is fixedly connected to the bottom of the sealing plate 5, and its bottom end extends into the flushing pipe 1 and is fixed with a disc 7.
[0029] The limiting plate 8 is sleeved on the outer periphery of the connecting column 6 and located above the disc 7. The limiting plate 8 has a through hole 9 in the center for the connecting column 6 to pass through. The limiting plate 8 is fixedly connected to the inner wall of the flushing pipe 1 by at least two symmetrically arranged fixing rods 10.
[0030] Flushing tube 1: Serves as a channel for the delivery of flushing fluid. Its inlet end is tightly connected to the flushing bottle 2 to ensure that the flushing fluid can flow smoothly into the bladder.
[0031] Rinse bottle 2: Used to hold the rinsing fluid, it is the liquid storage unit of the entire equipment. A hanging strap 3 is located at the center of its top, allowing the rinsing bottle to be suspended at a suitable height, allowing the rinsing fluid to flow naturally downwards under gravity. A float 4 is installed inside the cavity of rinsing bottle 2.
[0032] Float 4: Its density is less than that of the flushing fluid, allowing it to float in the flushing fluid. Its maximum buoyancy is greater than the total weight of the sealing plate 5 and the connecting column 6. This characteristic allows float 4 to move up and down according to the change in the flushing fluid level in flushing bottle 2.
[0033] Sealing disc 5: Fixed to the bottom of float 4, with a diameter larger than the inner diameter of the inlet opening of flushing tube 1. Made of medical-grade silicone, its bottom surface has a conical sealing surface that matches the shape of the inlet opening of flushing tube 1, which can effectively seal the inlet of flushing tube 1 and prevent air from entering the pipeline after the flushing fluid is used up.
[0034] Connecting column 6: The top end is fixedly connected to the bottom surface of the sealing plate 5, and the bottom end extends into the flushing pipe 1 and is fixed with a disc 7, which serves to connect the sealing plate 5 and the disc 7. At the same time, it moves in the flushing pipe 1 with the rise and fall of the float 4.
[0035] Disc 7: Its diameter is larger than the diameter of the through hole 9 of the limiting disc 8, and its bottom surface is provided with anti-slip texture. Driven by the connecting column 6, disc 7 can cooperate with the limiting disc 8 to achieve lifting and limiting of disc 7.
[0036] Limiting disc 8: Sleeves around the outer periphery of connecting post 6 and located above disc 7, with a through hole 9 in the center for connecting post 6 to pass through. It is fixedly connected to the inner wall of flushing pipe 1 by at least two symmetrically arranged fixing rods 10 to ensure its stable position. The limiting disc 8 is located 5-10mm below the inlet of flushing pipe 1, and the diameter of its through hole 9 is 0.5-1mm larger than the diameter of connecting post 6, ensuring that connecting post 6 can pass freely while limiting the rising height of disc 7.
[0037] Fixed rod 10: used to fix the limiting plate 8 to the inner wall of the flushing pipe 1, so that the limiting plate 8 maintains a stable position in the flushing pipe 1, and provides guidance and limiting function for the movement of the disc 7 and the connecting column 6.
[0038] Working principle: In the initial state of use, the flushing bottle 2 is suspended at a suitable height by the top strap 3, and the bottle is filled with flushing fluid. The inlet end of the flushing tube 1 is connected to the flushing bottle 2. Due to gravity, the flushing fluid begins to flow into the bladder through the flushing tube 1. At this time, the liquid level in the flushing bottle 2 is relatively high, and the float 4 is in a higher position due to the greater buoyancy.
[0039] As the rinsing process continues, the rinsing fluid in rinsing bottle 2 gradually decreases, and the fluid level begins to drop. Due to the reduced buoyancy, float 4 causes the connected sealing plate 5 and connecting column 6 to descend together. The disc 7 fixed to the bottom of connecting column 6 also descends accordingly.
[0040] As the liquid level in the rinsing bottle 2 drops to a certain level, the disc 7 gradually moves away from the limiting disc 8. Since the diameter of the disc 7 is larger than the diameter of the through hole 9 in the center of the limiting disc 8, the liquid inlet channel of the rinsing pipe 1 is restricted when the disc 7 moves away from the limiting disc 8. At this time, the flow rate of the rinsing liquid begins to slow down.
[0041] As the liquid level drops further, the float 4 continues to sink, and the sealing plate 5 also descends accordingly. When the flushing fluid in the flushing bottle 2 is about to run out, the sealing plate 5 descends until it completely covers the inlet opening of the flushing tube 1. Because the sealing plate 5 is made of medical-grade silicone and the conical sealing surface on its bottom matches the shape of the inlet opening of the flushing tube 1, it can form a good seal, effectively preventing air from entering the flushing tube 1.
[0042] Throughout the process, the limiting disc 8 is securely connected to the inner wall of the flushing pipe 1 via the fixing rod 10, providing precise guidance and limiting for the movement of the connecting column 6 and the disc 7. It is positioned 5-10mm below the inlet of the flushing pipe 1, and the diameter of the through hole 9 is 0.5-1mm larger than the diameter of the connecting column 6. This ensures that the connecting column 6 can move freely up and down while precisely controlling the rising height of the disc 7. This ensures that the equipment can orderly adjust the flushing fluid flow rate when the liquid level changes, and promptly seals the inlet end of the flushing pipe 1 before the flushing fluid is exhausted, achieving a safe and efficient bladder flushing operation.
[0043] Beneficial effects: Automatic control of flushing fluid flow rate and stop: Through the coordinated work of components such as float 4, sealing plate 5, connecting column 6, disc 7 and limit plate 8, the flushing fluid inlet can be sealed in time when the flushing fluid is about to run out, based on the change of the liquid level in the flushing bottle, thus stopping the flushing. This eliminates the need for frequent manual monitoring and improves work efficiency.
[0044] Preventing air from entering: The sealing plate 5 is made of medical-grade silicone, and the conical sealing surface on the bottom matches the shape of the inlet opening of the flushing tube 1, which can effectively seal the inlet of the flushing tube. After the flushing fluid is used up, it can prevent air from entering the pipeline, reduce the risk of infection, and ensure the safety of the flushing process.
[0045] Precise positioning and guidance: The limiting plate 8 is fixed to the inner wall of the flushing pipe 1 by the fixing rod 10, and its position is stable. It is set at a suitable position below the inlet of the flushing pipe 1. The diameter of the through hole is reasonably designed to ensure that the connecting column 6 can pass through freely, while precisely limiting the rising height of the disc 7. It provides precise guidance and positioning for the movement of the connecting column 6 and the disc 7, ensuring that the equipment can regulate the flow rate of the flushing fluid in an orderly manner.
[0046] Easy to use: The top of the rinsing bottle 2 is equipped with a hanging strap 3, which makes it easy to hang the rinsing bottle 2 at a suitable height and let the rinsing liquid flow down naturally by gravity. The operation is simple and convenient.
