Abstract
Description
Technical Field
[0001] This invention relates to the field of bladder irrigation technology, specifically to a bladder irrigation device with constant temperature and speed control alarm function. Background Technology
[0002] Bladder irrigation is a medical technique that involves injecting a sterile solution into the bladder through a catheter or cystostomy tube, using the siphon principle to drain the fluid and clean the bladder. It is mainly used to maintain catheter patency, remove blood clots or bacteria, treat bladder diseases, and help identify infections.
[0003] During prostate surgery (such as transurethral resection of the prostate) or bladder tumor resection, enlarged prostate tissue or tumors are removed. This process may result in tissue fragments and wound bleeding. If these substances are not promptly eliminated, they can accumulate in the bladder, forming blood clots that can block the catheter, leading to difficulty urinating, bladder overdistension, and even secondary massive bleeding. Therefore, a bladder irrigation device is needed to flush the bladder. Current irrigation methods use a continuously flowing saline solution to flush out residual substances and avoid the risk of blockage. However, since the saline solution is delivered via an IV bottle, which is often directly exposed to the outside environment, even when heated to a constant 37 degrees Celsius, the temperature may not remain constant in cold weather, causing inconvenience for subsequent irrigation. Summary of the Invention
[0004] The purpose of this invention is to provide a bladder irrigation device with constant temperature and speed control alarm function to solve the problems existing in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a bladder irrigation device with constant temperature and rate control alarm function, comprising an infusion stand and a catheter body inserted into the human bladder and communicating with a drainage bag, wherein a heat preservation device is installed on the surface of the infusion stand, and the heat preservation device comprises: A support base is fixed to the surface of the telescopic rod of the infusion stand, and a movable disc is rotatably connected to the top of the support base; The thermostatic section is fixed on both sides of the movable plate, and the size of the thermostatic section on both sides is adapted to the size of the infusion bottle; The second limiting component is located between the support base and the constant temperature section and is used to fix the constant temperature section after rotation.

[0007] Preferably, the heating element includes: The heat-conducting plate has an arc-shaped structure and is attached to the inner side of the infusion plate; A heating plate is installed on both sides inside the infusion plate. Several heat-conducting sheets are fixed on one side of the infusion plate and are arranged at equal intervals. The other end of the heat-conducting sheets passes through the infusion plate and is attached to the heat-conducting plate.
[0008] Preferably, the temperature-regulating part further includes a limiting member, the limiting member comprising: The limiting plate has one end bent and rotatably connected to one side of the cover plate; The locking block is fixed to one side of the infusion plate, and the limiting plate is engaged with the locking block after rotation.
[0009] Preferably, the second limiting member includes: The limiting convex ball slides through both sides of the top of the support base; One end of the spring is fixed to the bottom of the limiting protrusion, and the other end is fixed to the inner wall of the support base; The limiting hole and the slot are both located at the bottom of the connecting block. The limiting hole is located in the middle of the slot, and the two ends of the slot near the outer side are inclined outward.
[0010] Preferably, a reminder part is installed on the surface of the catheter body, the reminder part including: The first airbag is installed on the inner wall of the catheter body, and the inner wall of the inflated part is at the same level as the inner wall of the catheter body. The second balloon is fitted onto the surface of the catheter body. Several connecting tubes connect the second balloon to the first balloon, and the connecting tubes penetrate the inner wall of the catheter body.
[0011] Preferably, the diameter of the connecting tube is 0.1-0.2 mm, and the diameter of the second airbag after inflation is 2-3 mm.
[0012] Preferably, the surface of the cover plate is provided with an observation window, and the observation window is made of transparent material.

[0014] Preferably, the inner cavity of the support seat is provided with sliding grooves on both sides, and the two ends of the limiting protrusion are fixed with sliders, which are slidably connected on the surface of the sliding grooves.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, after the infusion bottle is placed inside the infusion plate, and the cover plate is fixed to the infusion plate, the heating element can be activated to heat the infusion bottle, keeping it at a constant temperature. This facilitates better subsequent bladder flushing. During flushing, if the catheter becomes blocked, the urine drainage path is obstructed, causing urine to accumulate in the catheter lumen upstream of the blockage point. The pressure gradually increases, and this pressure directly acts on the first balloon in the lumen, squeezing it. The squeezed balloon then enters the second balloon through the connecting tube, causing the second balloon to inflate. This serves as a reminder of the blockage in the catheter body.

Detailed Implementation
[0018] 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.
[0019] Please see Figure 1-9 As shown, a bladder irrigation device with constant temperature and speed control alarm function includes an infusion stand 100 and a catheter body 300 inserted into the human bladder and connected to a drainage bag. A heat preservation device 200 is installed on the surface of the infusion stand 100. The heat preservation device 200 includes a support base 210 fixed to the surface of the telescopic rod of the infusion stand 100. A movable plate 220 is rotatably connected to the top of the support base 210. A constant temperature section 230 is fixed on both sides of the movable plate 220. The size of the constant temperature section 230 is adapted to the size of the infusion bottle. The constant temperature section 230 includes connecting blocks 231 fixed to both sides of the movable plate 220. A support plate 232 is fixed to the other end of the connecting blocks 231. An infusion plate 236 is fixed to the top of the support plate 232. A temperature-controlled device is installed inside the infusion plate 236. A temperature sensor is used to monitor the temperature of the infusion bottle in real time and display it on the control panel 700. The size of the left infusion plate 236 is larger than that of the right infusion plate 236. A heating element 234 is installed on the inner side of the infusion plate 236. A cover plate 233 is hinged to the surface of the infusion plate 236. The back of the cover plate 233 is adapted to the inner side of the infusion plate 236. When heating the infusion bottle, the infusion bottle can be placed inside the infusion plate 236 as the cover plate 233 is opened. After placement, the cover plate 233 can be closed on the surface of the infusion plate 236. Then, the infusion bottle can be heated at a constant temperature by the heating element 234. A limiting member 240 is fixed between the support base 210 and the constant temperature part 230 to fix the constant temperature part 230 after rotation.
[0020] The heating element 234 includes a heat-conducting plate 2341 attached to the inner side of the infusion plate 236. It has an arc-shaped structure. Heating plates 2342 are installed on both sides inside the infusion plate 236. Several heat-conducting sheets 2343 are fixed on one side of the infusion plate 236 and are arranged at equal intervals. The other end of the heat-conducting sheet 2343 passes through the infusion plate 236 and is attached to the heat-conducting plate 2341. When the infusion bottle is heated, as the heat-conducting plate 2341 is heated, heat is transferred to the heat-conducting plate 2341 through the heat-conducting sheet 2343, so that the heat-conducting plate 2341 comes into contact with the infusion bottle, thereby keeping the infusion bottle warm.
[0021] The constant temperature section 230 also includes a limiting member 235, which includes a limiting plate 2351 rotatably connected to one side of the cover plate 233. One end of the limiting plate 2351 is bent. A locking block 2352 is fixed to one side of the infusion plate 236. After the limiting plate 2351 is rotated, it is locked to the locking block 2352. After the cover plate 233 and the infusion plate 236 are in contact, the limiting plate 2351 can be rotated so that the other end of the limiting plate 2351 is locked to the locking block 2352, thereby fixing the cover plate 233 and the infusion plate 236.
[0022] The second limiting component 240 includes limiting protrusions 241 that slide through both sides of the top of the support base 210. A spring 242 is fixed to the bottom of each limiting protrusion 241, and the other end of the spring 242 is fixed to the inner wall of the support base 210. Limiting holes 243 and slots 244 are provided at the bottom of each connecting block 231. The limiting holes 243 are located in the middle of the slots 244, and the two ends of the slots 244 near the outer side are inclined outwards. When switching between different support plates 232, as the movable disc 220 rotates on the top of the support base 210, the limiting protrusions... After 241 disengages from the interior of the limiting hole 243, the movable disk 220 can be rotated. After switching the two connecting blocks 231, the limiting protrusion 241 first enters the slot 244. Since the slot 244 is inclined, the limiting protrusion 241 will be squeezed into the interior of the support base 210 before entering the interior of the limiting hole 243. After the limiting protrusion 241 is located at the position of the limiting hole 243, the elastic force of the spring 242 causes the limiting protrusion 241 to be locked into the limiting hole 243, thereby fixing the position of the movable disk 220.
[0023] A reminder part 400 is installed on the surface of the catheter body 300. The reminder part 400 includes a first balloon 410 installed on the inner wall of the catheter body 300, and the inner wall of the reminder part 400 after inflation is at the same level as the inner wall of the catheter body 300. A second balloon 420 is sleeved on the surface of the catheter body 300. It is made of medical-grade silicone with a Shore hardness of 30-40, and has high elasticity and deformation recovery. Several connecting tubes 430 are connected between the second balloon 420 and the first balloon 410. The diameter of the connecting tubes 430 is 0.1-0.2 mm. The diameter of the second balloon 420 after inflation is 2-3 mm, which can quickly transmit pressure changes. The balloon response time is ≤3 seconds. When the balloon is inflated, it can intuitively indicate the severity of the blockage. 430 penetrates the inner wall of the catheter body 300. When the catheter becomes blocked, the urine drainage path is obstructed, and the urine in the lumen cannot flow smoothly to the drainage bag. The bladder continues to produce urine, causing urine to accumulate in the catheter lumen upstream of the blockage point, and the pressure gradually increases. This pressure acts directly on the first balloon 410 in the lumen and squeezes the first balloon 410. The squeezed balloon 410 will enter the second balloon 420 through the connecting tube 430, allowing the second balloon 420 to inflate. This facilitates the warning of the blockage in the catheter body 300. The deformation critical pressure of the first balloon 410 (2kPa) is higher than the normal drainage pressure to avoid false triggering, and lower than the dangerous pressure of bladder injury (3kPa), ensuring timely warning and safety.
[0024] The surface of the cover plate 233 is equipped with an observation window 800, which is made of transparent material. This allows the amount of liquid inside the infusion bottle to be observed through the observation window 800, facilitating subsequent replacement.
[0025] The surface of the infusion stand 100 is equipped with a control panel 700, and the control panel 700 contains a control board for operating the heating temperature of the heating plate 2342. This allows the heating of the heating plate 2342 to be controlled and observed through the surface display screen.
[0026] The inner cavity of the support base 210 is provided with sliding grooves 600 on both sides. The two ends of the limiting protrusion ball 241 are fixed with sliders 500. The sliders 500 slide on the surface of the sliding groove 600. This not only maintains the stability of the limiting protrusion ball 241 when it moves, but also prevents the limiting protrusion ball 241 from moving out excessively.
[0027] Working principle: In use, the catheter body 300 is inserted into the patient's bladder, and then the urine bag is connected to the catheter body 300. During bladder irrigation, the infusion bottle is placed inside the infusion plate 236 and abutted against the heating element 234. After placement, the cover 233 is closed, and then the limiting plate 2351 is rotated to engage with the locking block 2352, thus limiting the infusion bottle. The heating plate 2342 can then be heated via the control panel 700. The heat is conducted through the heat-conducting plate 2343 to the heat-conducting plate 2341, heating the infusion bottle. The heated temperature is transmitted to the surface of the control panel 700 for display via a temperature sensor. The heated infusion bottle then enters the catheter body 300 through the infusion tubing, and then into the patient's bladder for flushing. If the infusion bottle being flushed is small, the movable disc 220 can be rotated to switch the temperature control unit 230, and then the movable disc 220 is fixed by the limiting member 240. If the catheter body 300 becomes blocked during subsequent bladder irrigation, the urine drainage path is obstructed, and urine in the lumen cannot flow smoothly to the drainage bag. The bladder continues to produce urine, leading to urine accumulation in the catheter lumen upstream of the blockage point. The pressure gradually increases, directly acting on the first balloon 410 in the lumen and compressing it. The compressed balloon 410 then enters the second balloon 420 through the connecting tube 430, allowing the second balloon 420 to inflate and facilitate the sealing of the catheter body 300. When the situation is alerted, medical staff will release the blockage by flushing the catheter, adjusting its position, or replacing it. The catheter lumen will then be cleared, and urine will flow out smoothly. The pressure will quickly drop back to the initial range of 0.5-1 kPa. The first balloon 410 will lose its radial pressure constraint and will return to its natural contraction state under its own elasticity. The gas in the second balloon 420 will be drawn back into the airway by the restoring force of the first balloon 410. The second balloon 420 will gradually deflate and flatten, returning to its initial standby state, waiting for the next blockage trigger.
