When the device needs to be used to clean the patient's bladder, the operator opens the sealing plug of the feeding port on the liquid storage tank 301, and then adds cleaning liquid into the liquid storage tank 301. The liquid level of the cleaning liquid should be lower than the liquid storage tank. The position of the feeding port 301 prevents the cleaning liquid from being stored in the feeding port of the liquid storage tank 301. The operator pushes the moving support 1, and then inserts the right end of the connecting pipe 307 into the catheter 7. At this time, the left end of the catheter 7 In contact with the second drainage tube 512, the left end of the catheter 7 covers the annular groove of the connecting tube 307. Subsequently, the operator opens the solenoid valve on the upper left side of the infusion tube 306 through the console 2. At this time, the infusion tube 306 The inside is filled with gas. At this time, the piston 310 of the round table is sealed with the connecting pipe 307. Then, the operator starts the first electric slider 303 through the console 2. The first electric slider 303 drives the push rod 304 to move down, and the push rod 304 drives the The drain piston 305 and the support plate on it move downward, and the drain piston 305 squeezes the cleaning fluid in the liquid storage tank 301. Since the material of the drain piston 305 is rubber material, the drain piston 305 and the liquid storage tank 301 are formed. The tightness between them is increased, preventing the cleaning fluid from leaking out in the liquid storage tank 301, and achieving a better sealing effect.

The gas pressure in the infusion pipe 306 increases, the automatic exhaust valve 311 is opened, and the gas in the infusion pipe 306 is gradually discharged from the automatic exhaust valve 311. When the infusion pipe 306 is filled with cleaning liquid, the gas in the infusion pipe 306 is completely discharged, The effect of removing excess gas is achieved, and at the same time, it is ensured that the cleaning liquid in the infusion tube 306 will not be discharged, and the effect of reducing the waste of cleaning liquid is realized. When the upper surface is in contact, the amount of cleaning liquid in the liquid storage tank 301 is reduced equal to the amount of cleaning liquid in the infusion tube 306. In other words, whenever the upper left support plate of the push rod 304 is in contact with the upper surface of the second L-shaped rod 501 When contacting, the infusion tube 306 will be filled with cleaning liquid, to ensure that the amount of cleaning liquid entering the catheter 7 is equal to the amount of cleaning liquid in the quantitative box 502, and then, the push rod 304 drives the drainage piston 305 and the second L-shaped rod. 501 moves down, the spring on the second L-shaped rod 501 is compressed, the pressure in the infusion tube 306 increases, the round table piston 310 drives the sliding rod 309 to move to the right, the spring fixed with the fixing frame 308 is stretched, and the infusion tube 306 is communicated with the connecting pipe 307, the cleaning liquid in the infusion pipe 306 enters the patient's bladder through the connecting pipe 307, and the clear liquid discharge speed is controlled by adjusting the moving speed of the first electric slider 303 to achieve a better uniform speed The discharge effect, at this time, the pressure in the connecting tube 307, the catheter 7 and the patient's bladder are equal, and as the cleaning fluid enters the patient's bladder, the pressure data detected by the pressure sensor 312 gradually increases.

During the process of the circular truncated piston 310 moving to the right, the circular truncated piston 310 drives the three first limit rods 401 to move to the right, and the three first limit rods 401 gradually release the limit on the adjacent second limit rods 402 . After the infusion tube 306 is connected to the connecting tube 307, the torsion springs on the three first L-shaped rods 403 are initially in the accumulating state, the torsion springs on the three first L-shaped rods 403 begin to reset, and the three first L-shaped rods 403 The torsion springs on the rods 403 drive the adjacent clamping rods 404 to rotate, respectively, and the three clamping rods 404 respectively drive the adjacent second limit rods 402 to move outward. When adjacent to the outer side of the first limit rod 401, the right parts of the three clamping rods 404 clamp the urinary catheter 7 tightly, so as to avoid the pressure increase in the urinary catheter 7 and the separation of the connecting pipe 307. The inner side of the right part of the rod 404 is respectively set as an arc-shaped rod, the outer side of the connecting pipe 307 is provided with an annular groove, and the arc-shaped rods of the three clamping rods 404 are respectively matched with the annular grooves of the connecting pipe 307, so that the three clamping rods are clamped tightly. The right part of the rod 404 presses the left part of the outer side of the urinary catheter 7 into the annular groove of the connecting pipe 307 to achieve a better clamping and sealing effect. When the pressure sensor 312 detects that the pressure reaches a certain value, the operator passes The console 2 stops the first electric slider 303, and at the same time, the operator closes the solenoid valve on the infusion tube 306 through the console 2 to prevent the backflow of the cleaning fluid in the patient's bladder, and the infusion tube 306 stops transporting into the catheter 7 Cleaning fluid, the pressure in the infusion tube 306 no longer changes, and the spring fixed with the fixing frame 308 drives the circular piston 310 to move to the left to reset, and the circular piston 310 drives the three first limit rods 401 through the three springs on its right side. Reset, at this time, the second L-shaped rod 501 is quantitatively completed, and the cleaning fluid cleans the patient's bladder. After the cleaning fluid stays in the patient's bladder for a period of time, the patient's bladder is cleaned.

After the cleaning liquid has finished cleaning the patient's bladder, the operator opens the solenoid valve on the second drainage tube 512 through the console 2, and at the same time, the operator activates the second electric slider 508 through the console 2, and the second electric slider 508 The limit block 509 is driven to move downward, the limit block 509 drives the L-shaped limit rod 506 to move downward, and the L-shaped limit rod 506 drives the third limit rod 505 to move downward. FIG. 6 shows the second L-shaped rod 501 At this time, the second L-shaped rod 501 should be located below the third limit rod 505, the third limit rod 505 drives the pull rod 504 to move down, and the pull rod 504 drives the drainage piston 503 to move down, and the drainage piston The fixed spring of 503 is compressed, the air pressure between the upper part of the drainage piston 503 and the quantitative box 502 is reduced, the one-way valve on the left side of the top part of the quantitative box 502 is closed, and the one-way valve on the right side of the top part of the quantitative box 502 is opened. The cleaning fluid enters the quantitative box 502 through the catheter 7 through the connecting pipe 307, the second drainage pipe 512, the air bag 606 and the first drainage pipe 511. At this time, the pressure detected by the pressure sensor 312 gradually decreases. When the third limit rod 505 When the left end of the second L-shaped rod 501 contacts the right side of the lower part of the second L-shaped rod 501, the third limit rod 505 is squeezed by the second L-shaped rod 501 to move to the right, and the third limit rod 505 drives the L-shaped limit rod 506 to move to the right. Moving to the right, the spring fixed to the L-shaped limit rod 506 is stretched. When the third limit rod 505 no longer moves to the right, the wedge-shaped block of the L-shaped limit rod 506 and the limit groove of the limit block 509 are in contact with each other. The limit is released. At this time, the distance that the third limit rod 505 moves downward is equal to the distance that the second L-shaped rod 501 moves downward. At the same time, since the inner diameter of the quantitative box 502 is equal to the inner diameter of the liquid storage tank 301, the quantitative box The amount of the cleaning liquid in 502 is equal to the amount of the cleaning liquid entering the urinary catheter 7, which achieves the effect of comparing and detecting the amount of the discharged cleaning liquid and the amount of the drained cleaning liquid.

Subsequently, the spring fixed to the drainage piston 503 is reset, and the drainage piston 503 moves upward at this time, the pressure of the cleaning liquid in the quantitative box 502 increases, the one-way valve on the left side of the upper part of the quantitative box 502 is opened, and the upper right side of the quantitative box 502 is opened. The one-way valve is closed, and the drainage piston 503 discharges the cleaning fluid in the quantitative box 502 into the collection box through the drain pipe 510. When the cleaning fluid in the patient's bladder is completely drained, there is no need to control the stop position of the second electric slider 508. , realizes the effect of rapidly discharging the cleaning liquid in the quantitative box 502, avoids the cleaning liquid adhering to the quantitative box 502 for a long time, and causes impurities to remain on the inner wall of the quantitative box 502. When the cleaning liquid in the quantitative box 502 is completely discharged, the first The three limit rods 505 and the L-shaped limit rod 506 return to their original positions, the cleaning fluid drainage is completed, the operator resets the second electric slider 508 through the console 2, and the second electric slider 508 drives the limit block 509 to move upwards, When the limiting block 509 returns to the initial position, the left wedge-shaped block at the lower part of the L-shaped limiting rod 506 is snapped into the limiting groove of the limiting block 509 again, and the drainage of the cleaning liquid is completed.

During the process of introducing the cleaning solution in the patient's bladder into the quantitative box 502, if the pressure detected by the pressure sensor 312 drops to a negative pressure (lower than atmospheric pressure), it proves that the urinary catheter 7 is blocked. At this time, the operator passes the console 2. Stop the second electric slider 508. At this time, the drainage piston 503 no longer moves downward. Then, the operator starts the deceleration motor 601 through the console 2. The deceleration motor 601 drives the gear 602 to rotate, and the gear 602 drives the ring gear 605 to rotate. , the ring gear 605 pushes the adjacent protrusions 607 to squeeze the airbag 606 in turn through the two protrusions on the ring gear 605. Since the two protrusions on the inner side of the ring gear 605 and the six protrusions 607 are both smoothly arranged, the ring gear 605 is smooth. The resistance of 605 is smaller when rotating, which reduces the load of the deceleration motor 601 and prolongs the service life of the deceleration motor 601. By intermittently squeezing the air bag 606, the pressure in the air bag 606 fluctuates. Fluctuation occurs, the catheter 7 is gradually dredged, the effect of dredging the catheter 7 is realized, and the situation that the catheter 7 is blocked and cannot discharge the cleaning liquid in the patient's bladder is avoided. The material of the air bag 606 is an elastic material, so that the air bag is 606 automatically resets when it is not squeezed by external force, and the airbag 606 is ellipsoid. When the middle of the outer side of the airbag 606 is squeezed, the two ends will not change greatly, ensuring that the two ends of the airbag 606 will not pull the first drainage tube. 511 and the second drainage tube 512, since the traditional dredging method is for the medical staff to squeeze the second drainage tube 512 to achieve the effect of dredging, the six bumps 607 are arranged in the circumferential direction, and the six bumps 607 are squeezed. The method is alternate extrusion, the air bag 606 is evenly stressed, which increases the service life of the air bag 606, prevents the medical staff from different pressures when squeezing, and realizes the effect of dredging immediately after the catheter 7 is blocked, reducing the The time from the blockage of the urinary catheter 7 until the medical staff squeezes is shortened, and a better effect of quickly dredging the urinary catheter 7 is achieved.

When the pressure detected by the pressure sensor 312 returns to normal, the operator activates the second electric slider 508 through the console 2 , at this time, the drainage piston 503 moves down to discharge the cleaning fluid in the patient's bladder into the quantitative box 502 When the amount of cleaning liquid does not reach the discharge amount in the liquid storage tank 301, the L-shaped limit rod 506 and the limit block 509 will not contact the limit, which ensures that the drainage mechanism 5 completes the quantitative operation of the cleaning liquid. After all the cleaning liquid is discharged, the operator resets the second electric slider 508 through the console 2, and the second electric slider 508 drives the limit block 509 to move upward. When the limit block 509 returns to the original position, the L-shaped limit The limit block on the left side of the lower part of the rod 506 is re-inserted into the limit groove of the limit block 509, and the drainage of the cleaning fluid is completed. If multiple cleanings are required, the operator repeats the above steps. Holding the left ends of the three second limit rods 402 by hand, the three second limit rods 402 move relative to each other, and after the three second limit rods 402 are respectively limited by the adjacent first limit rods 401, the operator When the catheter 7 is pulled out, the device is used. The operator then disassembles the infusion tube 306 and then discharges the residual cleaning liquid in it. At the same time, the operator disassembles the liquid collecting tank and discharges the cleaning liquid in it.
