DETAILED DESCRIPTION
[0025] The utility model will be made further detailed explanation below combining with the drawings and specific embodiment
[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the bladder irrigation device of the embodiment includes Y-shaped catheter 1 for inserting into the bladder, infusion tube 2 detachably connected to the right end of the rear side of the catheter 1, drainage tube 3 detachably connected to the left end of the rear side of the catheter 1, urine discharge tube 4 detachably connected to the rear end of the drainage tube 3, urine bag 5 detachably connected to the rear end of the urine discharge tube 4, clean liquid bag 6 detachably connected to the rear end of the infusion tube 2, control assembly 7 arranged between the infusion tube 2 and the drainage tube 3 and used for controlling the flow rate of liquid in the catheter 1, observation assembly 8 arranged on the drainage tube 3 and used for judging the pressure in the bladder, and sealing assembly 9 arranged at the front part of the catheter 1.
[0027] The control assembly 7 includes fixing strip 71 arranged in the left-right direction and fixedly arranged below the drainage tube 3 and fixedly connected to the lower side of the infusion tube 2, fixing plate 72 arranged between the drainage tube 3 and the infusion tube 2 and fixedly connected to the upper side of the fixing strip 71, rotating shaft 73 rotatably arranged at the upper part of the fixing plate 72 in the front-rear direction, rotating plate 74 fixedly arranged on the rotating shaft 73, a pair of compression members 75 respectively fixedly arranged on the left and right sides of the rotating plate 74 and used for extruding and compressing the drainage tube 3 or the infusion tube 2, and a pair of locking subassemblies 76 respectively arranged below the compression members 75 and used for making the compression members 75 relatively stationary or relatively movable with respect to the fixing plate 72.
[0028] The observation assembly 8 includes pressure measuring tube 81 fixedly arranged on the drainage tube 3 and located in front of the compression members 75 and in communication with the drainage tube 3, and check valve 82 fixedly arranged at the communication part of the pressure measuring tube 81 and the drainage tube 3.
[0029] When using this product, place the saline solution in the cleansing bag 6 and hang the bag up. This allows the saline solution to continuously flow into the catheter 1 along the infusion tube 2, and then into the bladder. The saline solution that accumulates in the bladder dilutes the impurities and flows out along the drain tube 3. When the patient has not flushed for a long time, viscous substances can easily accumulate in the bladder. In this case, the operator presses down on the left compression component 75, causing it to rotate downwards along the shaft 73. This reduces the gap between the left compression component 75 and the fixing strip 71, compressing the left drain tube 3. This makes it difficult for the liquid to flow out of the drain tube 3, thus allowing the liquid that continuously flows into the bladder from the infusion tube 2 to remain in the bladder. The accumulation of saline solution in the bladder causes it to fill with saline solution, increasing the pressure and flushing out impurities. This flushes out substances adhering to the bladder. The pressure is monitored through the pressure measuring tube 81. If the bladder is full of saline solution, further filling will cause the pressure to open the check valve 82 and enter the pressure measuring tube 81, flushing out the contents of the bladder. Pressing and rotating the right-side compression component 75 compresses the infusion tube 2, slowing the inflow of saline solution. Simultaneously, the drainage tube 3 opens, expelling the wastewater. Slowing the inflow of saline solution allows for rapid and complete drainage, preventing substances from remaining in the bladder due to the saline solution.
[0030] like Figure 2 and Figure 4 As shown, the lower left and right ends of the fixing strip 71 are respectively provided with limiting grooves 10. Each locking sub-assembly 76 includes a flexible movable strip 761 that is embedded in the corresponding limiting groove 10 and whose upper end is fixedly connected to the lower part of the corresponding side compression member 75, a number of hollow grooves 762 that are spaced apart along the length direction of the movable strip 761 on the movable strip 761, and a number of flexible movable plates 763 that are movably arranged corresponding to each hollow groove 762.
[0031] The lower ends of each movable plate 763 are fixedly connected to the lower inner wall of the corresponding hollow groove 762.
[0032] When using this product, by pulling the movable strip 761 on the side where the liquid flow needs to be compressed and slowed down, the compression component 75 is driven to rotate downward, thereby reducing the gap between the compression component 75 and the fixed strip 71, thus compressing the pipe and adjusting the liquid flow rate. After adjusting to the appropriate position, the free end of the movable plate 763 in the hollow groove 762 closest to the lower side of the limiting groove 10 is pushed outward, causing the movable plate 763 to abut against the lower side of the fixed strip 71 and restricting the movement of the movable strip 761, thereby fixing the rotation angle of the compression component 75.
[0033] like Figure 1 and Figure 2As shown, the sealing assembly 9 includes a flexible sealing ring 91 on the outer tube wall of the catheter 1 at the front portion in the front-rear direction, and a fixed rubber ring 92 fixed to the rear side of the sealing ring 91 and having its edge bonded to the outside of the bladder.
[0034] When the product is used, after the front end of the catheter 1 is inserted into the bladder, the fixed rubber ring 92 is pushed forward, so that the front sealing ring 91 is attached to the bladder and blocks the gap between the bladder and the catheter. Then, the fixed rubber ring 92 keeps the sealing and blocking state, preventing the liquid in the bladder from overflowing.
[0035] As shown in Figure 1 , Figure 2 and Figure 5 , the urine bag 5 is provided with a negative pressure air bag 11 at the front portion, the negative pressure air bag 11 is connected to the urine bag 5 through a gas conveying pipe 12, the negative pressure air bag 11 is provided with an air exhaust valve 13 for one-way flow of air from the inside of the negative pressure air bag 11 to the outside, and the gas conveying pipe 12 is provided with an inflation valve 14 for one-way flow of air from the inside of the urine bag 5 to the inside of the negative pressure air bag 11.
[0036] When the product is used, when it is observed that the rate of waste liquid flowing into the urine bag 5 is seriously slowed down, the caregiver squeezes the negative pressure air bag 11 to exhaust the air in the negative pressure air bag 11 from the air exhaust valve 13, and then the negative pressure air bag 11 is reset under the elastic action of itself, so that the air pressure in the negative pressure air bag 11 is lower than the air pressure in the urine bag 5, thereby causing the air in the urine bag 5 to be filled into the negative pressure air bag 11 through the inflation valve 14, so that the air pressure in the urine bag 5 is reduced to be lower than the air pressure in the urine discharge pipe 4, so that under the action of atmospheric pressure, the liquid and impurities in the urine discharge pipe 4 and the liquid discharge pipe 3 are driven to flow into the urine bag 5, thereby solving the problem of blockage of the urine discharge pipe 4 and the liquid discharge pipe 3 by contaminated substances.
[0037] The working principle of the device is as follows:
[0038] First step: insert the catheter 1 into the bladder of the patient, and push the fixed rubber ring 92 forward, so that the front sealing ring 91 is attached to the bladder and blocks the gap between the bladder and the catheter. Then, the fixed rubber ring 92 keeps the sealing and blocking state, preventing the liquid in the bladder from overflowing.
[0039] The second step: physiological saline is placed in the clean liquid bag 6, and the clean liquid bag 6 is hung, so that the physiological saline continuously flows into the catheter 1 along the infusion tube 2, and then flows into the bladder, and the physiological saline accumulated in the bladder dilutes the dirt in the bladder and flows out along the drainage tube 3, when the patient does not flush for a long time, the viscous material is easy to accumulate in the bladder, at this time, the operator drives the left movable strip 761 downward, so that the left compression part 75 is driven to rotate downward, the gap between the compression part 75 and the fixed strip 71 is reduced, so that the drainage tube 3 is compressed, and the flow rate of the liquid is adjusted, when the adjustment is adjusted to the appropriate position, the free end of the movable plate 763 in the hollow groove 762 closest to the lower side of the limiting groove 10 is pushed outward, so that the movable plate 763 abuts against the lower side of the fixed strip 71 and limits the movement of the movable strip 761, so that the rotation angle of the left compression part 75 is fixed, the liquid is not easy to flow out of the drainage tube 3, so that the liquid continuously flowing into the bladder from the infusion tube 2 is accumulated in the bladder, so that the bladder is filled with physiological saline, and the pressure is increased, so that the dirt is washed away, and the material adhered in the bladder is washed down.
[0040] The third step: through the pressure measuring tube 81, if the bladder is filled with physiological saline, the liquid continuously filled in the bladder will open the check valve 82 under the action of pressure and enter the pressure measuring tube 81, which represents that the material in the bladder is washed down at this time.
[0041] The fourth step: the right compression part 75 is pressed to compress the infusion tube 2, so that the physiological saline is slowed down, and the drainage of the drainage tube 3 is opened, so that the waste water filled with dirt is discharged, and the physiological saline is slowed down, so that the waste water can be quickly and completely discharged, and the problem that part of the material is retained in the bladder due to the influence of the physiological saline is avoided.
[0042] The fifth step: because there are many materials in the waste water discharged, the urine tube 4 is blocked, the caregiver squeezes the negative pressure air bag 11, the gas in the negative pressure air bag 11 is discharged from the exhaust valve 13, and then the negative pressure air bag 11 is reset under the action of its elasticity, so that the air pressure in the negative pressure air bag 11 is lower than the air pressure in the urine bag 5, so that the air in the urine bag 5 flows into the negative pressure air bag 11 through the inflation valve 14, so that the air pressure in the urine bag 5 is reduced and is lower than the air pressure in the urine tube 4, so that the liquid and impurities in the urine tube 4 and the drainage tube 3 are driven to flow into the urine bag 5 under the action of atmospheric pressure.
[0043] The above merely describes the specific implementation of the present application, and does not limit the patent range of the present application, any equivalent structural transformation or direct or indirect application in other related technical fields based on the content of the present application is also included in the patent protection range of the present application.
