Description

Technical Field

[0001] The present invention relates to the technical field of medical cleaning tools, and particularly relates to a flushing and drainage device for wound stomas. Background Art

[0002] Wound stoma, also known as intestinal diversion surgery, mainly includes temporary intestinal stomas after anastomosis of the intestinal tract in the patient's abdominal cavity, or permanent intestinal stomas for patients in the advanced stage of tumorous lesions due to intestinal obstruction. By lifting the stoma intestinal tube to the abdominal wall to establish an artificial anus, the problem of the patient excreting metabolic waste can be solved.

[0003] The abdominal wall stoma needs to be cleaned in a timely manner to prevent infection. The existing cleaning method is generally water flushing, but water flushing is prone to spillage and requires more cleaning utensils, which is inconvenient in operation.

[0004] To solve the above problems, a Chinese patent with the publication number CN219332752U discloses a wound stoma cleaning device, which includes symmetrically arranged connecting columns. A cleaning water cavity is fixedly connected to the two connecting columns. The upper end of the cleaning water cavity is hermetically connected to a collection cavity. An arc-shaped groove is arranged at the upper end of the collection cavity. One end of the arc-shaped groove is open, and the other end is closed. Collection holes are formed in the arc-shaped groove. A mesh plate is fixedly connected to the upper end of the collection holes of the arc-shaped groove; the arc-shaped groove is convenient for guiding the flow. Align the arc-shaped groove towards the wound stoma. When flushing the wound stoma, the cleaning water enters the arc-shaped groove and falls into the collection cavity through the mesh plate, which is convenient and comprehensive for collection; through the operation of a water pump, the water in the cleaning water cavity can be sprayed out from the nozzle along the connecting pipe to clean the wound stoma. This cleaning device is easy to use, combines a cleaning water cavity and a water collection cavity, comprehensively collects the cleaning waste liquid while cleaning the wound stoma, and simplifies the daily nursing work of the wound stoma.

[0005] The above device has the following problems in actual use: After the patient undergoes anesthesia surgery, there will be several residues and remnants adhering to the wound stoma due to the operations during the surgical process. Therefore, it is necessary to clean the residues and remnants in a timely manner. However, when the device actually cleans the wound stoma, it only flushes the wound stoma through the nozzle. But the residues and remnants will increase the adhesion force to the wound stoma as the wound stoma gradually recovers, that is, the water pressure sprayed out by the nozzle is not enough to effectively remove the residues and remnants adhering to the wound stoma, resulting in poor cleaning effect and poor practicability. Summary of the Invention

[0006] The present invention provides a flushing and drainage device for wound stomas to solve the problem that the existing cleaning device cannot effectively remove the residues and remnants adhering to the wound stoma.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a flushing and drainage device for wound ostomy, comprising a water tank and a drainage box with an opening at the bottom, the water tank is fixedly connected to the top of the drainage box, and also comprises a drainage mechanism arranged in the drainage box; the drainage mechanism comprises a drainage tube, a cylindrical tube, a cleaning component symmetrically arranged on both sides of the drainage tube along the axial direction of the drainage tube, and a driving component for driving the drainage tube to rotate; the drainage tube is rotatably connected to the drainage box, and the drainage tube is communicated with the water tank; the cylindrical tube is fixedly connected to the drainage tube, and the cylindrical tube is communicated with the drainage tube, and a plurality of water outlet holes are opened on the cylindrical tube; the cleaning component comprises a moving block, a fixed plate, a bristle layer, and a driving part for driving the moving block to perform vertical reciprocating motion; the moving block is slidably connected to the cylindrical tube; the fixed plate is connected to the moving block; the bristle layer is fixedly connected to the fixed plate.

[0008] The principles and advantages of this solution are:

[0009] 1. The free end of the bristle layer is placed against the wound stoma, and the bristle layer rotates synchronously during the rotation of the cylindrical tube. During the rotation of the bristle layer, the bristle layer has a certain force, so the bristle layer can more fully clean the residues and residues adhering to the wound stoma, so that the residues and residues can be quickly washed away in the subsequent water flushing process, thereby enhancing the flushing effect.

[0010] Furthermore, during the rotation of the bristle layer, the moving block can drive the bristle layer to perform vertical reciprocating motion. Therefore, while the bristle layer rotates circumferentially, the bristle layer can also perform vertical reciprocating motion. During the vertical downward motion of the bristle layer, the bristle layer is subjected to the reaction force of the wound stoma, and the bristle layer will deform. During the deformation of the bristle layer, the action range of the bristle layer is expanded, that is, the contact area between the bristle layer and the wound stoma is increased, further enhancing the cleaning effect of the bristle layer on the residue and residue, and ensuring that the bristle layer can efficiently clean the residue and residue.

[0011] In summary, through the circumferential movement of the bristle layer and the vertical reciprocating movement of the bristle layer, the debris and residues adhering to the wound stoma can be completely cleaned, the amount of debris and residues adhering to the wound stoma is reduced, and the force of the debris and residues adhering to the wound stoma is weakened, preparing for the subsequent further flushing of the debris and residues.

[0012] 2. During the rotation of the cylindrical tube, the water in the cylindrical tube will be sprayed out from the water outlet. During the spraying of water from the cylindrical tube, the water has a certain centrifugal force, which can expand the scope of water action, so that the water will spread out over a large area and act on the wound stoma. That is, the water can fully and comprehensively flush the wound stoma, thereby cleaning the wound stoma, reducing postoperative complications, reducing the probability of bacterial infection, improving the utilization rate of water, and enhancing the flushing effect of water.

[0013] Moreover, during the diffusion of water, it can act on the bristle layer, making the bristle layer wet. After the bristle layer becomes wet, it has a certain adsorption force, enabling the residues and leftovers remaining on the wound stoma to be adsorbed by the bristle layer, thereby further reducing the amount of residues and leftovers adhering to the wound stoma, enhancing the cleaning effect of the bristle layer, and improving the cleaning efficiency of the bristle layer.

[0014] Furthermore, the cleaning assembly also includes a linkage part; the linkage part includes a swing block, a rotating shaft, a first cam, and a power part for driving the rotating shaft to rotate; one end of the linkage block is hinged to the moving block, and the other end of the swing block is fixedly connected to the fixed plate; the rotating shaft is rotatably connected to the cylindrical tube; the first cam is fixedly connected to the rotating shaft, and the swing block is located on the movement track of the first cam.

[0015] During the movement of the bristle layer, when the convex part of the first cam collides with the swing block, the swing block will swing. When the convex part of the first cam no longer collides with the swing block, the swing block will reset under its own gravity. During the swing of the swing block, the bristle layer moves synchronously. During the swing of the bristle layer, the acting force of the bristle layer can be further enhanced. Therefore, the bristle layer can more easily clean the residues and leftovers. At the same time, during the swing of the bristle layer, the acting range of the bristle layer will also be further expanded, enabling the bristle layer to come into contact with and clean more residues and leftovers, thereby further improving the cleaning efficiency of the bristle layer.

[0016] In summary, through the combined action of the rotation, vertical reciprocating movement, and swing of the bristle layer, the bristle layer can comprehensively and thoroughly clean the residues and leftovers adhering to the wound stoma. That is, it ensures that the residues and leftovers can be completely removed under the combined action of the bristle layer and the water outlet holes, improves the cleaning quality of the wound stoma, and accelerates the recovery speed of the wound stoma.

[0017] Furthermore, a flapping blade is fixedly connected to the rotating shaft, and the bristle layer is located on the movement track of the flapping blade.

[0018] During the rotation of the flapping blade, on the one hand, the flapping blade can act on the bristle layer, thereby making the deformation degree of the bristle layer larger, further expanding the acting range of the bristle layer, increasing the acting force of the bristle layer, enhancing the acting effect of the bristle layer, and improving the acting efficiency of the bristle layer. That is, it ensures that the residues and leftovers remaining on the wound stoma can be cleaned more completely and comprehensively.

[0019] Moreover, when flushing the wound stoma, the flapping leaves can flap the water being flushed, thereby causing the water to spatter, expanding the scope of action of the water, enabling the water to come into more uniform and sufficient contact with the wound stoma, enhancing the flushing effect of the water, improving the cleaning efficiency of the water, further reducing the probability of bacterial infection, and accelerating the recovery rate of the wound stoma.

[0020] Furthermore, it further includes a water spraying part; the water spraying part includes a water spraying unit and power units symmetrically arranged on both sides of the cylindrical pipe along the diameter direction of the cylindrical pipe; the water spraying unit includes a plurality of water spraying members; each water spraying member includes a water spraying pipe and a water spraying hole opened on the cylindrical pipe; the water spraying pipe is fixedly connected to the cylindrical pipe and is communicated with the water spraying hole; the power unit includes a first guiding cylinder, a first guiding block, a first spring, a long plate, and a plurality of water spraying blocks equidistantly arranged along the length direction of the long plate; the first guiding cylinder is fixedly connected to the cylindrical pipe, and the first guiding block is slidably connected to the first guiding cylinder; both ends of the first spring are respectively connected to the first guiding cylinder and the first guiding block; the long plate is fixedly connected to the first guiding block, and the cam abuts against the long plate; the water spraying block is fixedly connected to the long plate, and the water spraying port of the water spraying pipe is located on the movement track of the water spraying block.

[0021] During the flow of water in the cylindrical pipe, a part of the water will flow out along the water spraying pipe. During the flow of water in the water spraying pipe, when the convex part of the first cam abuts against the long plate, the long plate drives the water spraying block to move towards the position where the water spraying pipe is located. During the movement of the water spraying block, when the water spraying block gradually adheres to the water spraying port of the water spraying pipe, the diameter of the water spraying pipe during water spraying will be reduced. After the diameter of the water spraying pipe during water spraying is reduced, the pressure in the water spraying pipe will increase. That is, when two adjacent water spraying blocks gradually approach each other, the acting distance during water spraying of the water spraying pipe can be increased, and the acting force during water spraying of the water spraying pipe can be enhanced. Furthermore, the water spraying pipe can perform a more significant flushing on the residues and remnants remaining at the wound stoma, further weakening the acting force of the residues and remnants adhering to the wound stoma, ensuring that the residues and remnants remaining at the wound stoma can be completely flushed away.

[0022] During the flow of water in the water spraying pipe, when the convex part of the first cam no longer abuts against the long plate, the long plate drives the water spraying block to move away from the position where the water spraying pipe is located. During the movement of the water spraying block, the diameter of the water spraying pipe of the water spraying pipe gradually becomes larger, thereby increasing the flow rate of the water flowing out of the water spraying pipe, and the acting force of the water flushing is relatively gentle. Thus, the water spraying pipe can better flush the residue debris remaining at the wound stoma, enhancing the flushing effect on the residue debris, reducing the quantity of the residue debris remaining at the wound stoma, reducing the probability of secondary infection at the wound stoma, and accelerating the recovery time of the wound stoma.

[0023] In summary, by changing the diameter of the water spray pipe, it is possible to comprehensively and completely wash away the residues, remnants, and debris remaining at the wound stoma, enhancing the effect of wound stoma flushing and ensuring the quality of wound stoma flushing.

[0024] Furthermore, it further includes a blocking part; the blocking part includes a rubber filling block, a blocking hole opened on the cylindrical pipe, a blocking block for sealing the blocking hole, and a movement unit for driving the blocking block to perform vertical reciprocating motion; the blocking block is slidably connected to the blocking hole; the rubber filling block is located inside the cylindrical pipe, and the rubber filling block is fixedly connected to the blocking block.

[0025] By driving the blocking block to perform vertical reciprocating motion through the movement unit, when the blocking block drives the rubber filling block to move towards the position where the water outlet hole is located, until the rubber filling block abuts against the bottom of the inner wall of the cylindrical pipe, the rubber filling block continues to move, and the rubber filling block is squeezed and deformed. During the deformation of the rubber filling block, the contact area between the rubber filling block and the bottom of the inner wall of the cylindrical pipe expands, so that the rubber filling block can block a part of the water outlet holes, thereby reducing the number of water jets from the water outlet holes. After the number of water jets from the water outlet holes decreases, the pressure inside the cylindrical pipe will increase, so that when the water is discharged from other water spray holes and from the water spray pipe, the acting force of the sprayed water is stronger and the spraying distance is farther, ensuring that the pressurized water can more thoroughly wash the residues and remnants at the wound stoma, and further improving the quality of flushing.

[0026] During the movement of the rubber filling block away from the position where the water outlet hole is located, the number of water jets from the water outlet holes returns to the initial state, that is, the acting force of the water sprayed from the water outlet holes and the water spray pipe is relatively gentle, which can comprehensively wash the loose residues, remnants, and debris, further reducing the number of residues, remnants, and debris at the wound stoma and improving the flushing efficiency.

[0027] Furthermore, the cleaning component further includes a pressurizing part; the pressurizing part includes a piston cylinder, a piston block, and a driving unit for driving the piston block to perform reciprocating motion along the length direction of the piston cylinder; the piston cylinder is fixedly connected to the drainage pipe; the piston block is slidably connected to the piston cylinder; an air inlet pipe and an air outlet pipe are communicated with the piston cylinder; the free end of the air outlet pipe is communicated with the cylindrical pipe.

[0028] Through the mutual cooperation of the piston block and the piston cylinder, the piston block can continuously draw in and discharge compressed gas into the air outlet pipe. During the flow of the compressed gas, the compressed gas can further accelerate the water flow rate inside the cylindrical pipe, enhance the water pressure, and increase the acting force and acting distance of the water sprayed from the water outlet holes and the water spray pipe, further ensuring that the water can perform a more significant flushing effect on the wound stoma and improving the water flushing efficiency.

[0029] Furthermore, the pressurizing section further includes an auxiliary unit; the auxiliary unit includes a connecting plate, a screw rod, a guide rod, a nut seat, a vertical block, an auxiliary block, a second spring, and an auxiliary member for driving the screw rod to rotate forward and backward; the connecting plate is fixedly connected to the piston cylinder; the screw rod is rotatably connected to the connecting plate; the guide rod is fixedly connected to the connecting plate; the nut seat is threadedly connected to the screw rod, and the nut seat is slidably connected to the guide rod; the vertical block is fixedly connected to the piston block; the auxiliary block is slidably connected to the nut seat, and the auxiliary block is located on the movement track of the vertical block; both ends of the second spring are respectively connected to the auxiliary block and the nut seat; the air outlet pipe is an elastic pipe, and the air outlet pipe is located on the movement track of the auxiliary block.

[0030] Under the combined action of the nut seat and the vertical block, the auxiliary block can continuously squeeze the air outlet pipe. After being squeezed by the auxiliary block, the air outlet pipe can reduce the diameter when discharging compressed air, so that the pressure inside the air outlet pipe becomes larger. That is, after the compressed air is further pressurized by the air outlet pipe, the acting force of the compressed air can be enhanced, so that the compressed air can flow farther in the cylindrical pipe, further expanding the flow range of the compressed air, and then enhancing the flow effect of the water in the cylindrical pipe, ensuring that the water in the cylindrical pipe is pressurized more comprehensively and fully.

[0031] Furthermore, the cleaning component further includes a linkage unit; the linkage unit includes a fixed block, a rotating shaft, an elliptical disc, a rubber plug, a linkage hole opened on the cylindrical pipe, and a linkage member for driving the rotating shaft to rotate; the fixed block is fixedly connected to the drainage pipe; the rotating shaft is rotatably connected to the fixed block; the elliptical disc is fixedly connected to the rotating shaft; the rubber plug is fixedly connected to the linkage hole, and the elliptical disc abuts against the rubber plug.

[0032] Through the mutual cooperation of the elliptical disc and the rubber plug, the rubber plug can be continuously squeezed and deformed. During the deformation of the rubber plug, a negative pressure can be formed inside the rubber plug, so that the rubber plug can further pressurize the water flowing in the cylindrical pipe, making the water flow faster in the cylindrical pipe, acting over a longer distance, and having a better flushing effect.

[0033] Furthermore, the driving part is a third spring; both ends of the third spring are respectively connected to the moving block and the cylindrical pipe; the moving block is located on the movement track of the rubber filling block.

[0034] During the vertical reciprocating movement of the rubber filling block, when the rubber filling block abuts against the moving block, the moving block moves vertically downward under the drive of the rubber filling block, and the third spring is compressed; when the rubber filling block no longer abuts against the moving block, the moving block resets under the action of the third spring, and the moving block moves vertically upward. Therefore, the moving block can make vertical reciprocating movements.

[0035] Furthermore, the power part is a belt; both ends of the belt are respectively sleeved on the rotating shaft and the rotating axis.

[0036] During the rotation of the rotating shaft, the rotating shaft rotates synchronously under the drive of the belt. Brief Description of the Drawings

[0062] Specific implementation process:

[0063] After the anesthesia surgery is completed, the medical staff can hold the anti-slip groove 45 of the water tank 1 through the mechanical arm. Before the mechanical arm moves the water tank 1, the free end of the bristle layer 6 is first placed against the wound stoma, and then the water tank 1 is moved. During the movement of the water tank 1, the water in the water tank 1 is injected into the drainage tube 3 through the water pump in the water tank 1, and finally discharged through the water outlet 49.

That is, the water can fully and comprehensively flush the wound stoma, thereby cleaning the wound stoma, reducing postoperative complications, reducing the probability of bacterial infection, improving the utilization rate of water, and enhancing the flushing effect of water.

[0065] Moreover, during the diffusion period, the water can act on the bristle layer 6, making the bristle layer 6 moist. After the bristle layer 6 is moistened, the bristle layer 6 has a certain adsorption force, so that the residues and residues remaining on the wound stoma can be adsorbed by the bristle layer 6, thereby further reducing the amount of residues and residues adhering to the wound stoma, enhancing the cleaning effect of the bristle layer 6, and improving the cleaning efficiency of the bristle layer 6.

[0066] During the rotation of the cylindrical tube 4, the bristle layer 6 rotates synchronously. During the rotation of the bristle layer 6, the bristle layer 6 has a certain force, so the bristle layer 6 can more fully clean the residues and residues adhering to the wound stoma, so that the residues and residues can be quickly washed away during the subsequent water flushing process, thereby enhancing the flushing effect. In addition, during the rotation of the bristle layer 6, the fixed block 32 moves circumferentially with the drainage tube 3. During the circumferential movement of the fixed block 32, the rotating shaft 33 moves synchronously. During the circumferential movement of the rotating shaft 33, the third gear 48 moves synchronously. During the movement of the third gear 48, the third gear 48 is engaged with the second annular rack 44, and then the third gear 48 rotates. During the rotation of the third gear 48, the rotating shaft 33 rotates synchronously. Therefore, while the rotating shaft 33 moves circumferentially, the rotating shaft 33 can also rotate.

[0067] During the rotation of the rotating shaft 33, the second cam 39 rotates synchronously. During the rotation of the second cam 39, when the convex part of the second cam 39 abuts against the piston block 23, the piston block 23 moves towards the position where the drainage tube 3 is located, and the second spring 31 is compressed; when the convex part of the second cam 39 no longer abuts against the piston block 23, the piston block 23 resets under the action of the second spring 31, and the piston block 23 moves away from the position where the drainage tube 3 is located. Therefore, the piston block 23 can perform horizontal reciprocating motion.

[0068] During the horizontal reciprocating motion of the piston block 23, since the rack 43 meshes with the second gear 42, the second gear 42 can rotate forward and backward. During the forward and backward rotation of the second gear 42, the screw rod 26 rotates synchronously. During the rotation of the screw rod 26, the nut seat 28 can drive the rubber filling block 20 to perform vertical reciprocating motion through the pushing block 38. During the vertical reciprocating motion of the rubber filling block 20, when the rubber filling block 20 abuts against the moving block, the moving block moves vertically downward under the drive of the rubber filling block 20, and the third spring is compressed; when the rubber filling block 20 no longer abuts against the moving block, the moving block resets under the action of the third spring, and the moving block moves vertically upward. Therefore, the moving block can perform vertical reciprocating motion.

[0069] The moving block can drive the brush layer 6 to perform vertical reciprocating motion. Therefore, while the brush layer 6 rotates circumferentially, the brush layer 6 can also perform vertical reciprocating motion. During the vertical downward movement of the brush layer 6, the brush layer 6 receives a reaction force from the wound stoma, and the brush layer 6 will deform. During the deformation of the brush layer 6, the acting range of the brush layer 6 expands, that is, the contact area between the brush layer 6 and the wound stoma increases, further enhancing the cleaning effect of the brush layer 6 on the residue and the remaining matter, and ensuring that the brush layer 6 can efficiently clean the residue and the remaining matter.

[0070] During the rotation of the rotating shaft 33, the rotating shaft 33 drives the rotating shaft 12 to rotate through the belt 36. During the rotation of the rotating shaft 12, the first cam 13 rotates synchronously. During the vertical reciprocating motion of the brush layer 6, when the convex part of the first cam 13 collides with the swing block 11, the swing block 11 will swing. When the convex part of the first cam 13 no longer collides with the swing block 11, the swing block 11 will reset under its own gravity. During the swing of the swing block 11, the brush layer 6 moves synchronously. During the swing of the brush layer 6, the acting force of the brush layer 6 can be further enhanced. Therefore, the brush layer 6 can more easily clean the residue and the remaining matter. At the same time, during the swing of the brush layer 6, the acting range of the brush layer 6 will also be further expanded, so that the brush layer 6 can contact and clean more residue and remaining matter, thereby further improving the cleaning efficiency of the brush layer 6.

[0071] Meanwhile, during the rotation of the rotating shaft 12, the flapping blade 14 rotates synchronously. During the rotation of the flapping blade 14, on the one hand, the flapping blade 14 can act on the brush hair layer 6, thereby making the deformation degree of the brush hair layer 6 larger, further expanding the action range of the brush hair layer 6, increasing the acting force of the brush hair layer 6, enhancing the action effect of the brush hair layer 6, and improving the action efficiency of the brush hair layer 6. That is, it ensures that the residues and remnants remaining at the wound stoma can be cleaned more completely and comprehensively.

[0072] Moreover, when water flushes the wound stoma, the flapping blade 14 can flap the water being flushed, thereby causing the water to splash, expanding the action range of the water, enabling the water to contact the wound stoma more evenly and fully, enhancing the flushing effect of the water, improving the cleaning efficiency of the water, further reducing the probability of bacterial infection, and accelerating the recovery speed of the wound stoma.

[0073] During the flow of water in the cylindrical tube 4, a part of the water will flow out along the water spray pipe 15. During the flow of water in the water spray pipe 15, when the convex part of the first cam 13 abuts against the long plate 18, the long plate 18 drives the water spray block 19 to move towards the position where the water spray pipe 15 is located, and the first spring is compressed. During the movement of the water spray block 19, when the water spray block 19 gradually abuts against the water spray orifice of the water spray pipe 15, the diameter of the water spray pipe 15 during water spraying is reduced. After the diameter of the water spray pipe 15 during water spraying is reduced, the pressure in the water spray pipe 15 will increase. That is, when two adjacent water spray blocks 19 gradually approach, the acting distance during water spraying of the water spray pipe 15 can be increased, the acting force during water spraying of the water spray pipe 15 can be enhanced, and thus the water spray pipe 15 can perform a more significant flushing on the residues and remnants remaining at the wound stoma, further weakening the acting force of the residues and remnants adhering to the wound stoma, and ensuring that the residues and remnants remaining at the wound stoma can be completely flushed away.

[0074] During the flow of water in the water spray pipe 15, when the convex part of the first cam 13 no longer abuts against the long plate 18, the long plate 18 resets under the action of the first spring, and the long plate 18 drives the water spray block 19 to move away from the position where the water spray pipe 15 is located. During the movement of the water spray block 19, the diameter of the water spray pipe 15 of the water spray pipe 15 gradually becomes larger, and thus the flow rate of the water flowing out of the water spray pipe 15 increases, and the acting force of the water flushing is relatively gentle. Therefore, the water spray pipe 15 can better flush the residue debris remaining at the wound stoma, enhance the flushing effect on the residue debris, reduce the quantity of the residue debris remaining at the wound stoma, reduce the probability of secondary infection at the wound stoma, and accelerate the recovery time of the wound stoma.

[0075] In summary, through the change in the diameter of the water spray pipe 15, it is possible to comprehensively and completely wash the residues, residual substances, and residue debris remaining at the wound stoma, enhancing the effect of wound stoma flushing and ensuring the flushing quality of the wound stoma.

[0076] During the vertical reciprocating movement of the plugging block 21 driving the rubber filling block 20, when the rubber filling block 20 moves towards the position where the water outlet hole 49 is located, until the rubber filling block 20 abuts against the bottom of the inner wall of the cylindrical pipe 4, the rubber filling block 20 continues to move, and the rubber filling block 20 is squeezed and deformed. During the deformation of the rubber filling block 20, the contact area between the rubber filling block 20 and the bottom of the inner wall of the cylindrical pipe 4 expands, so that the rubber filling block 20 can block a part of the water outlet holes 49, thereby reducing the number of water sprays from the water outlet holes 49. After the number of water sprays from the water outlet holes 49 decreases, the pressure inside the cylindrical pipe 4 will increase, so that when the water is discharged from other water spray holes and from the water spray pipe 15, the acting force of the sprayed water is stronger and the spraying distance is farther, ensuring that the pressurized water can more thoroughly wash the residues and residual substances at the wound stoma, and further improving the flushing quality.

[0077] When the rubber filling block 20 moves away from the position where the water outlet hole 49 is located, the number of water sprays from the water outlet hole 49 returns to the initial state, that is, the acting force of the water sprayed from the water outlet hole 49 and the water spray pipe 15 is relatively gentle, and it can comprehensively wash the loose residues, residual substances, and residue debris, further reducing the number of residues, residual substances, and residue debris at the wound stoma and improving the flushing efficiency.

[0078] During the horizontal reciprocating movement of the piston block 23, through the mutual cooperation of the piston block 23 and the piston cylinder 22, the piston block 23 can continuously pump the compressed gas into and out of the air inlet pipe 24. During the flow of the compressed gas, the compressed gas can further accelerate the water flow rate inside the cylindrical pipe 4, enhance the water pressure, and increase the acting force and acting distance when the water is sprayed from the water outlet hole 49 and the water spray pipe 15, further ensuring that the water can more significantly wash the wound stoma and improving the water flushing efficiency.

[0079] During the vertical reciprocating movement of the nut seat 28 and during the horizontal reciprocating movement of the vertical block 29 along with the piston block 23, the auxiliary block 30, under the combined action of the nut seat 28 and the vertical block 29, can continuously squeeze the air outlet pipe 24. After being squeezed by the auxiliary block 30, the air outlet pipe 24 can reduce the diameter when discharging compressed air, so that the pressure inside the air outlet pipe 24 increases. That is, after the compressed air is pressurized again through the air outlet pipe 24, the acting force of the compressed air can be enhanced, so that the compressed air can flow a farther distance inside the cylindrical pipe 4, further expanding the flow range of the compressed air, and then enhancing the flow effect of water inside the cylindrical pipe 4, ensuring that the water inside the cylindrical pipe 4 is pressurized more comprehensively and fully.

[0080] During the rotation of the rotating shaft 33, the elliptical disk 34 rotates synchronously. Through the mutual cooperation of the elliptical disk 34 and the rubber plug 35, the rubber plug 35 can be continuously squeezed and deformed. During the deformation of the rubber plug 35, a negative pressure can be formed inside the rubber plug 35, and then the rubber plug 35 can further pressurize the water flowing inside the cylindrical pipe 4, making the water flow faster inside the cylindrical pipe 4, acting over a farther distance, and having a better flushing effect.
