[0002] Clinically, patients who have undergone prostate or bladder surgery usually need bladder irrigation. A bladder irrigation device is usually used to drain the irrigation fluid into the bladder through the urethra. The irrigation fluid removes postoperative blood clots, necrotic tissue and other foreign bodies from the bladder and then drains them into the collection device through the catheter of the collection device, reducing the risk of urethral obstruction.

[0003] In the process of using a catheter to drain the flushing fluid in the bladder to a collection device, since the flushing fluid contains blood clots or necrotic tissues and other substances, when the blood clots or necrotic tissues and other substances are large in volume, the blood clots or necrotic tissues and other substances are likely to block the catheter, thereby causing poor drainage;

[0004] When the catheter has poor drainage, medical staff usually perform unblocking operations on the catheter. Specifically, they usually use a syringe to draw physiological saline, then connect the syringe to the catheter and gently inject and withdraw it, repeating the operation until the blockage is discharged. Although the above method can achieve the purpose of unblocking the catheter, the need to use other instruments besides drainage such as syringes increases the inconvenience of the catheter unblocking operation.

[0005] Therefore, how to improve the convenience of catheter unblocking is a technical problem that urgently needs to be solved. Utility Model Content

[0026] As a preferred technical solution of the present application, an air outlet is provided on the liquid collecting device, and the air outlet is used for exhausting air.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] 1. In the scheme of the present application, a cover body and a slot are provided, and the slot allows the catheter to pass through, so that the slot limits the catheter and prevents the catheter from falling out of the slot. When the cover body rotates relative to the winding column and the base around the central axis direction of the winding column, the cover body can drive the catheter to rotate relative to the winding column and the base, thereby changing the winding amount of the catheter on the winding column. The provision of the cover body and the slot can improve the convenience of winding the catheter on the winding column and facilitate the storage of excessively long catheters. At the same time, on the basis of the catheter being wound on the winding column, the cover body is moved relative to the base in a direction close to the base, so that the winding area corresponding to the winding column is lowered, so that the catheter wound on the winding column is squeezed by the cover body and the base at both ends. After the catheter is squeezed, it can drive the catheter to rotate. The flushing liquid in the tube moves, so that the flushing liquid in the catheter can generate a certain impact force, so that when the catheter has poor drainage, the catheter wrapped around the winding column is squeezed, so that the impact force generated by the flushing liquid in the catheter can push away the blood clots or necrotic tissues and other substances blocking the liquid inlet end of the catheter, so as to dredge the catheter, and because the catheter can be wound around the winding column for multiple turns, when the catheter is squeezed, a longer section of the catheter can be squeezed, thereby increasing the amount of flushing liquid squeezed in the catheter, thereby increasing the impact force generated by the flushing liquid, and thereby improving the efficiency of catheter dredging. The device of the present application does not require additional instruments other than drainage such as syringes when dredging the catheter, and can further improve the convenience of catheter dredging operation;

[0029] 2. Furthermore, by setting the catheter matching area, when the catheter is squeezed in the catheter matching area, the part squeezed by the catheter matching area on the catheter is the area between the wound part on the catheter and the liquid outlet end of the catheter. In this way, when the movement of the cover body is controlled to squeeze the catheter cover body and the base wound on the winding column, at this time, since a certain point in the area between the wound part on the catheter and the liquid outlet end of the catheter is blocked, most of the squeezed flushing liquid in the catheter moves toward the direction close to the liquid inlet end of the catheter, thereby further improving the impact strength of the flushing liquid on the blood clot or necrotic tissue and other substances blocked at the liquid inlet end of the catheter, and further improving the dredging effect of the catheter;

[0030] 3. Further, by setting a locking assembly, when the lock head and the lock seat are matched in the initial state, the lock head and the lock seat form a one-way limiting structure, so that the movement of the extrusion piece relative to the base in the direction close to the base is locked, and the extrusion piece can move relative to the base in the direction away from the base. In this way, when the lock head is in the initial state, the catheter wound on the winding column can be prevented from being squeezed by the cover body and the base in this state, thereby providing stability when the catheter is in the drainage operation, and under the action of its one-way limiting structure, the winding area corresponding to the winding column can be increased in one direction. In this way, in the process of winding the catheter on the winding column, the size of the winding area can be adjusted according to the length of the wound catheter, so that the wound catheter can still be in a conductive state, thereby ensuring the smoothness of catheter drainage; at the same time, by controlling the control rod to release the lock head and the lock seat, at this time, the extrusion piece can move relative to the base in the direction close to or away from the base. In this state, the movement of the cover body can be controlled so that the cover body and the base squeeze the wound catheter. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0042] Embodiment 1: This embodiment provides a bladder flushing flushing liquid collection device, see Figure 1-Figure 6 As shown, it comprises a catheter 1, a liquid collecting device 2 and an extruding device 3, wherein the liquid collecting device 2 is used to collect the flushing liquid, and the extruding device 3 comprises a base 4 and an extruding member 5, wherein the base 4 and the extruding member 5 are movably matched, so that the extruding member 5 can move relative to the base 4 along the length direction of the base 4;

[0043] The extrusion member 5 includes a winding column 6 and a cover 7. The cover 7 is provided with a slot 8 for allowing the catheter 1 to pass through. The winding column 6 is used to wind the catheter 1. When the cover 7 on the extrusion member 5 moves relative to the base 4 toward the base 4, the winding area corresponding to the winding column 6 is lowered, and the catheter 1 wound on the winding column 6 can be squeezed by the cover 7 and the base 4.

[0044] Furthermore, the cover body 7 can rotate around the central axis of the winding column 6 relative to the winding column 6 and the base 4.

[0045] In the present application, by providing a cover body 7 and a slot 8, the slot 8 can allow the catheter 1 to pass through, so that the slot 8 limits the catheter 1 and prevents the catheter 1 from escaping from the slot 8. When the cover body 7 rotates around the central axis direction of the winding column 6 relative to the winding column 6 and the base 4, the cover body 7 can drive the catheter 1 to rotate relative to the winding column 6 and the base 4, thereby changing the winding amount of the catheter 1 on the winding column 6. The provision of the cover body 7 and the slot 8 can improve the convenience of winding the catheter 1 on the winding column 6, and is convenient for storing the overly long catheter 1; at the same time, on the basis of the catheter 1 being wound on the winding column 6, by moving the cover body 7 relative to the base 4 in a direction close to the base 4, the winding area corresponding to the winding column 6 is lowered, so that the catheter 1 wound on the winding column 6 is squeezed by the cover body 7 and the base 4 at both ends, and the catheter 1 is squeezed After being pressed, the flushing liquid in the catheter 1 can be driven to move, so that the flushing liquid in the catheter 1 can generate a certain impact force. Therefore, when the catheter 1 has poor drainage, the catheter 1 wrapped around the winding column 6 is squeezed, so that the impact force generated by the flushing liquid in the catheter 1 can push away the blood clots or necrotic tissues and other substances blocking the liquid inlet end of the catheter 1, so as to dredge the catheter 1. Moreover, since the catheter 1 can be wound around the winding column 6 for multiple turns, when the catheter 1 is squeezed, a longer section of the catheter 1 can be squeezed, thereby increasing the amount of flushing liquid squeezed in the catheter 1, thereby increasing the impact force generated by the flushing liquid, and thereby improving the dredging efficiency of the catheter 1. The device of the present application does not require additional instruments other than drainage such as syringes when dredging the catheter 1, which can further improve the convenience of the dredging operation of the catheter 1.

[0046] As a preferred embodiment, on the basis of the above method, further, a catheter matching area 9 is provided on the base 4, and the catheter matching area 9 is used to selectively squeeze the catheter 1 to control the unblocking of the catheter 1.

[0047] Furthermore, by setting the catheter fitting area 9, when the catheter fitting area 9 squeezes the catheter 1, the portion squeezed by the catheter fitting area 9 on the catheter 1 is the area between the wrapped portion on the catheter 1 and the liquid outlet end of the catheter 1. In this way, when the movement of the cover body 7 is controlled to squeeze the catheter 1 cover body 7 and the base 4 wrapped around the winding column 6, at this time, since a certain point in the area between the wrapped portion on the catheter 1 and the liquid outlet end of the catheter 1 is blocked, most of the squeezed flushing fluid in the catheter 1 moves toward the direction close to the liquid inlet end of the catheter 1, thereby further improving the impact strength of the flushing fluid on materials such as blood clots or necrotic tissues blocking the liquid inlet end of the catheter 1, and further improving the unblocking effect of the catheter 1.

[0048] As a preferred embodiment, on the basis of the above-mentioned method, further, the catheter matching area 9 includes a first pressure block 10 and a second pressure block 11, the first pressure block 10 is fixed on the base 4, and the second pressure block 11 moves or rotates relative to the base 4, and the movement of the second pressure block 11 relative to the base 4 is controlled to change the distance between the first pressure block 10 and the second pressure block 11, so that the first pressure block 10 and the second pressure block 11 squeeze the catheter 1 or release the squeezing effect on the catheter 1.

[0049] Furthermore, by setting the first pressing block 10 and the second pressing block 11 and changing the distance between the first pressing block 10 and the second pressing block 11, the clamping effect of the catheter 1 between the first pressing block 10 and the second pressing block 11 is changed, so that the first pressing block 10 and the second pressing block 11 squeeze the catheter 1 or release the squeezing effect on the catheter 1, thereby improving the convenience of controlling the unblocking of the catheter 1.
