In the present embodiment, the two pressing members are a first pressing plate 17 and a second pressing plate 18, respectively. The first extrusion plate 17 and the second extrusion plate 18 are provided with extrusion holes 19.

The hard end part 1 is provided with a first liquid channel 12, the upper end of the first liquid channel 12 is communicated with the telescopic sleeve 16, and the lower end of the first liquid channel 12 is communicated with the sliding hole. The extrusion seals the other end of the corresponding telescoping tube 16. The hard end part 1 is provided with a second liquid channel 13, and the upper end of the second liquid channel 13 is communicated with the sliding hole. The second liquid passage 13 is opposite to the first liquid passage 12 in the up-down direction. The other end of the second liquid channel 13 is fixedly connected with a connecting hose 14, and the second liquid channel 13 is communicated with the connecting hose 14. The connecting hose 14 is located at the gap between the drain hose 5 and the flushing pipe, and the end of the connecting hose 14 remote from the second liquid channel 13 communicates with the drain hose 5. The upper ends of the S-shaped channel 8 and the vertical channel 9,S and the upper ends of the vertical channel 8 and the vertical channel 9 are arranged on the connecting block 7 and penetrate through the upper end face of the connecting block 7, and the lower ends of the S-shaped channel 8 and the vertical channel 9 penetrate through the lower end face of the connecting block 7. The upper ends of the S-shaped channels 8 and the vertical channels 9 cooperate with the lower ends of the first liquid channels 12. The lower end of the vertical channel 9 cooperates with a second liquid channel 13. The lower end of the S-shaped channel 8 cooperates with the flushing channel 6. A baffle 15 is fixedly arranged in the flushing channel 6, and the baffle 15 is matched with the vertical channel 9. When the connection block 7 enters the flushing channel 6, the vertical channel 9 is blocked by the baffle 15.

In a normal state, the connecting block 7 is positioned at a gap between the drainage hose 5 and the flushing pipe, one end of the vertical channel 9 is communicated with the first liquid channel 12, and the other end of the vertical channel 9 is communicated with the second liquid channel 13. When the connection block 7 enters the flushing channel 6 and closes off the flushing channel 6, the upper end of the S-shaped channel 8 communicates with the first liquid channel 12. The lower end of the S-shaped channel 8 extends into the flushing channel 6, so that the liquid injection device is communicated with the first liquid channel 12 through the flushing channel 6 and the S-shaped channel 8, and flushing liquid is injected into the telescopic tube 16, so that the telescopic tube 16 is gradually stretched, and the two extrusion parts are gradually close to each other. The two extrusions crush the blood clots or stones in the groove 3.

The fixation module comprises an air bag 23. The air bag 23 is annular, and the air bag 23 is fixedly sleeved on the outer circumference of the hard end part 1. The balloon 23 is located below the upper end opening of the flushing channel 6. The flushing pipe is provided with a gas channel 24, one end of the gas channel 24 is communicated with the air bag 23, and the other end of the gas channel 24 is connected with an external inflation device. The inflator inflates the airbag 23. The inflator is of prior art. The inflator is not shown in the drawings. When the hard end 1 is placed in the urethra of the patient, the balloon 23 is inflated to expand the balloon 23, the balloon 23 is abutted against the urethra of the patient, and the hard end 1 is fixed.

The drainage device and the liquid injection device are provided with the gauges, so that the liquid quantity flowing out of the bladder, namely the liquid outlet quantity, can be accurately obtained, and the liquid quantity injected into the bladder of the patient, namely the liquid injection quantity, can be obtained. The urine volume produced by the patient can be obtained through the liquid outlet volume and the liquid injection volume, and the urine volume produced by the patient can be counted conveniently.

Working principle: initially, the connection piece 7 is located at the gap between the drainage hose 5 and the hard end 1. Under the action of the elastic pull rope 22, the telescopic tube 16 is contracted into the first mounting groove, and the first extrusion plate 17 is abutted against the inner wall of the groove 3. The airbag 23 is in an uninflated state. The first liquid channel 12, the vertical channel 9 and the second liquid channel 13 are communicated.

The flushing channel 6 is communicated with the liquid injection device, the drainage hose 5 is communicated with the drainage device, and the gas channel 24 is communicated with the inflation device.

The end of the hard tip 1 is inserted into the bladder through the patient's urethra. Wherein the opening at the upper end of the irrigation channel 6 is located in the bladder. Then, the air is inflated into the balloon 23 by the inflator, so that the balloon 23 is inflated to be larger, and the balloon 23 is abutted against the inside of the urethra of the patient, thereby fixing the hard end portion 1. While the balloon 23 seals the urethra so that fluid in the bladder cannot flow out through the urethra.

And then the flushing liquid is conveyed into the bladder of the patient through the flushing channel 6 by the priming device, the drainage device is started, and the liquid in the bladder of the patient flows out through the groove 3, the through hole 4 and the drainage hose 5. Thereby achieving the purpose of flushing the bladder of the patient.

During the irrigation process, blood clots or stones within the patient's bladder flow with the fluid. If the outer diameter of the clot or stone is smaller than the inner diameter of the through-hole 4, the clot or stone flows out with the liquid. When the outer diameter of the blood clot is larger than the inner diameter of the through hole 4, the blood clot will be caught in the through hole 4 to block the through hole 4.

When the blood clot is stuck in the through hole 4 and plugs the through hole 4, the plugged blood clot is partially located in the through hole 4 and partially located in the groove 3. Fluid within the patient's bladder cannot flow out through the through-holes 4. Because the drainage device continues to work, negative pressure is generated in the drainage hose 5, the drainage hose 5 is further flattened gradually, the middle parts of the two arc sections are close to each other, the two ends of the arc sections are gradually stretched, and the flow area of the drainage hose 5 is gradually reduced. However, the middle parts of the two arc sections are not completely attached, and the drainage hose 5 is in a communication state, so that after the through hole 4 is dredged, liquid in the groove 3 can smoothly flow out through the drainage hose 5. The connection block 7 slides into the flushing channel 6 and the vertical channel 9 moves into the flushing channel 6. The connecting block 7 seals off the flushing channel 6, and the baffle 15 shields the vertical channel 9 on the connecting block 7. While the S-shaped channel 8 is opposite to the first liquid channel 12 and the lower end of the S-shaped channel 8 is moved into the flushing channel 6. The portion of the flushing channel 6 located below the connection block 7 communicates with the first liquid channel 12 via the S-shaped channel 8, i.e. the first liquid channel 12 communicates with the priming device. The priming device delivers irrigant through the irrigation channel 6, the S-channel 8, the first liquid channel 12 into the telescopic tube 16. As the flushing fluid in the telescoping tube 16 increases, the flushing fluid pushes the extrusion in a direction away from the corresponding first mounting groove, the telescoping tube 16 stretches, and the elastic pull cord 22 stretches. The first compression plate 17 and the second compression plate 18 are brought close to each other, and thus compress the blood clot jammed in the through-hole 4. With the relative movement of the first compression plate 17 and the second compression plate 18, the clot is compressed into a plurality of small pieces by the compression members. Until the first pressing plate 17 and the second pressing plate 18 are attached to each other, the blade 20 enters the notch 21, and the blade 20 cuts the blood clot at the end of the through hole 4, so that the part of the blood clot entering the through hole 4 is separated from the part outside the through hole 4. So that the blood clot can pass smoothly through the through-hole 4.

After the blocked blood clot is cleaned, namely after the through hole 4 is dredged, liquid in the bladder of the patient can smoothly enter the drainage hose 5 through the through hole 4, and the drainage hose 5 is restored under the action of self elasticity. The connection block 7 slides away from the flushing channel 6, and the connection block 7 moves from within the flushing channel 6 into the gap between the drain hose 5 and the hard end 1. The irrigation channel 6 is opened and the infusion channel delivers irrigation fluid through the irrigation channel 6 into the bladder of the patient. The first liquid channel 12, the vertical channel 9 and the second liquid channel 13 are communicated, and under the action of the elastic pull rope 22, the two extrusion parts move away from each other, so that the telescopic sleeve 16 is shortened. The liquid in the hard end 1 flows into the drainage hose 5 through the first liquid passage 12, the vertical passage 9, the second liquid passage 13, and the connection hose 14, and is discharged to the outside. The flushing device can now continue the flushing operation.

Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
