Urology flushing device

Abstract

The present invention provides a urological flushing device, including a urinary catheter, a drainage tube and an infusion set. The urinary catheter includes a tube body and an air bag, and a sewage discharge channel and a water injection channel are arranged in the tube body. The air bag is used to fix the urinary catheter and prevent it from accidentally falling off. The infusion set supplies flushing liquid to the urinary catheter through a filling tube, and sprays it into the bladder through a first sewage discharge hole, so that pollutants can be discharged smoothly. The sewage discharge pipe is connected to the drainage tube to discharge the contaminated liquid into the catheter bag. The device adopts a shunt tube and a valve structure to make the bladder flushing more thorough. The infusion set uses a rocker to drive the pump body, so that the flushing liquid is continuously pumped, thereby improving the operating efficiency. The present invention can reduce the flushing time, improve the patient's comfort, and reduce the workload of medical staff, and is suitable for postoperative care in urological surgery.

Description

Technical Field

[0001] The invention relates to the technical field of medical appliances, in particular to a urology flushing device. Background Art

[0002] After urological surgery, impurities such as blood clots, tissue fragments, and bacteria may remain in the patient's bladder. If these contaminants are not discharged in time, they will increase the risk of infection and affect postoperative recovery. Therefore, it is usually necessary to flush the bladder to remove residual contaminants and reduce the incidence of infection. At present, bladder flushing mainly relies on gravity drip flushing or manual pressurized flushing. The former has a low flushing pressure and it is difficult to effectively remove impurities deposited at the bottom of the bladder; although the latter can improve the flushing efficiency, the flushing pressure is not easy to control, which may cause damage to the bladder wall and increase patient discomfort. In addition, during the flushing process, due to structural limitations, the traditional urinary catheter cannot evenly spray the flushing fluid, which makes it difficult to thoroughly clean certain areas inside the bladder and easily forms dead corners for residual contaminants.

[0003] The existing urinary catheterization devices still have the problem of catheter blockage during use. Since urine contains components such as urate and protein, long-term indwelling catheters are prone to crystal deposition, which in turn blocks the lumen and affects urine drainage and bladder flushing. Some improved urinary catheterization devices use porous structures or set additional drainage channels to improve drainage capacity, but it is still difficult to avoid the risk of lumen blockage. In addition, when traditional urinary catheters are removed, due to insufficient collapse of the airbag, mechanical damage to the urethra may be caused, increasing the patient's pain.

[0004] In response to the above problems, researchers and medical device manufacturers have been constantly trying to improve the structure of the catheter to enhance its flushing effect, reduce lumen blockage, and improve patient comfort. For example, some patented technologies propose adding auxiliary flushing channels in the catheter, or designing injection holes at the tip of the catheter to improve the spray range of the flushing fluid. However, these solutions still have shortcomings such as complex structure, high manufacturing cost, and inconvenient operation, which are difficult to meet clinical needs. Summary of the invention

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] like Figures 1 to 11 As shown, a urological irrigation device comprises:

[0044] The urinary catheter 3 comprises a tube body 32 and an air bag 31; a sewage discharge channel 321 and a water injection channel 325 are arranged in the tube body 32; the air bag 31 is fixed at one end of the tube body 32; a sewage discharge pipe, a water injection pipe and a liquid filling pipe are arranged at the other end of the tube body 32; the sewage discharge pipe and the liquid filling pipe are communicated with the sewage discharge channel 321; the water injection pipe is communicated with the air bag 31 through the water injection channel 325; a first sewage discharge hole 322 is arranged at one end of the urinary catheter 3 close to the air bag 31, and the first sewage discharge hole 322 is communicated with the sewage discharge channel 321; after water is injected into the air bag 31, it is stuck at the bladder opening of the patient to fix the urinary catheter 3 to prevent the urinary catheter 3 from accidentally falling off; urine and pollutants in the bladder enter the sewage discharge channel 321 of the urinary catheter 3 through the first sewage discharge hole 322;

[0045] The drainage tube 4 has one end connected to the drainage pipe and the other end connected to the urine catheter bag 5; urine and pollutants enter the drainage pipe through the drainage channel 321, and then flow into the urine catheter bag 5 through the drainage tube 4;

[0046] The infusion set 1 is connected to the filling tube through the hose 2; it is used to store the flushing liquid, output the flushing liquid from the first drainage hole 322 to the patient's bladder through the hose 2, the filling tube, and the drainage channel 321, and flush the pollutants in the patient's bladder into the catheter 3 and then discharge them out of the body.

[0047] In this embodiment, Robert clamps are provided on the drainage tube 4 and the hose 2 to clamp the drainage tube 4 and the hose 2 .

[0048] In this embodiment, a water injection soft valve is provided on the water injection pipe, which is used to inject water into the airbag 31 or suck water out of the airbag 31 through a syringe; a check valve is provided on the liquid filling pipe, which is used to inject flushing liquid into the catheter 3 in one direction to prevent the backflow of pollutants in the catheter 3; and a detachable plug is provided on the sewage pipe.

[0049] In this embodiment, the airbag 31 includes an integrally formed sleeve 312 and a balloon 317; the sleeve 312 is sleeved and fixed on the tube body 32; a shunt tube 315 is arranged between the sleeve 312 and the balloon 317; a first shunt hole 316 is arranged on the balloon 317, and a second shunt hole 314 is arranged on the sleeve 312; the two ends of the shunt tube 315 are respectively connected to the first shunt hole 316 and the second shunt hole 314; a third shunt hole 324 connecting the second shunt hole 314 and the sewage channel 321 is arranged on the tube body 32; the first shunt hole 316 is located between the first sewage hole 322 and the second shunt hole 314; the diameter of the third shunt hole 324 is larger than the outer diameter of the shunt tube 315. In the initial state, one end of the shunt tube 315 close to the tube body 32 passes through the third shunt hole 324 and is placed in the drainage channel 321, reducing the space occupied by the airbag 31 to avoid increasing the pain of the patient when the urinary catheter 3 is implanted. At the same time, the shunt tube 315 blocks the drainage channel 321 in the drainage channel 321, and when the urinary catheter 3 is implanted, it can prevent the drainage tube from being connected to the catheter bag 5, resulting in urine and pollutants leaking out; after the urinary catheter 3 is implanted, the balloon 317 is pushed into the drainage channel 321. The balloon 317 is inflated by injecting water therein, and during the expansion process, the shunt tube 315 is pulled out of the drainage channel 321, making the drainage channel 321 unobstructed. The fully inflated balloon 317 is stuck at the patient's bladder opening, and high-level urine and pollutants enter the drainage channel 321 through the first drainage hole 322 and are discharged from the body. Low-level pollutants at the periphery of the balloon 317 enter the drainage channel 321 through the shunt tube 315 and are discharged, so that the pollutants in the bladder are discharged more thoroughly.

[0050] Preferably, the urinary catheter 3 further includes an elastic tie 313; the elastic tie 313 is placed in the drainage channel 321, one end of the elastic tie 313 is fixedly connected to the tube body 32, and the other end passes through the third shunt hole 324 and the second shunt hole 314 to extend into the shunt tube 315 and is fixedly connected to the shunt tube 315. When the balloon 317 is filled with water and expanded, the elastic tie 313 is stretched. When the urinary catheter 3 is taken out, the water in the balloon 317 is pumped out. When the balloon 317 retracts, the elastic tie 313 assists in pulling one end of the shunt tube 315 into the drainage channel 321, so that the balloon 31 returns to its initial state, which facilitates the removal of the urinary catheter 3 and avoids increasing the pain of the patient.

[0051] In this embodiment, the urinary catheter 3 further includes a valve 311; the valve 311 is placed in the drainage channel 321 and is arranged in close contact with the third shunt hole 324; one end of the valve 311 close to the first drainage hole 322 is fixedly connected to the tube body 32, and one end away from the first drainage hole 322 is provided with a recovery hole for the shunt tube 315 to pass through. The shunt tube 315 passes through the recovery hole and enters the balloon 317 or is retracted into the drainage channel 321; when there are pollutants and urine in the patient's bladder to be discharged, the pollutants and urine enter the shunt tube 315 to open the lower end of the valve 311, open the recovery hole, and then flow into the drainage channel 321; when the urine in the bladder is discharged and flushing liquid needs to be injected for flushing, the valve 311 is attached to the third shunt hole 324, and the flushing liquid is only sprayed from the first drainage hole 322 in a high position, so that the coverage area of ​​the flushing liquid spray is larger, which is convenient for fully flushing the pollutants inside the bladder.

[0052] In this embodiment, a receiving groove 323 for receiving and releasing the shunt tube 315 is provided on the outside of the tube body 32, which is used to receive and release the shunt tube 315 connected to the first shunt hole 316 of the balloon 317, thereby reducing the space occupied by the shunt tube 315 when it is received and released.

[0053] In this embodiment, the infusion device 1 includes a shell 15, a liquid storage cup 11, an infusion tube 14, a liquid collecting ring 16, a power assembly and multiple pump bodies 18; a handle is fixedly provided on the outside of the shell 15; the liquid storage cup 11, the infusion tube 14, the liquid collecting ring 16, and the pump body 18 are fixed on the shell 15; an annular guide cavity 161 is provided inside the liquid collecting ring 16; the liquid storage cup 11 is placed above the liquid collecting ring 16; multiple pump bodies 18 are distributed on the outside of the liquid storage cup 11 in a circular array with the axis of the liquid storage cup 11 as the center; the liquid inlet of the pump body 18 is connected to the liquid storage cup 11, and the liquid outlet is connected to the liquid collecting ring 16; one end of the infusion tube 14 is connected to the hose 2, and the other end is connected to the liquid collecting ring 16; the power assembly is installed on the shell 15, and is used to drive the pump body 18 to pump the flushing liquid in the liquid storage cup 11 into the annular guide cavity 161 of the liquid collecting ring 16.

After the rubber sleeve 185 is pressed down, the air inside the rubber sleeve 185 enters the pump chamber and is discharged through the liquid outlet. When the rubber sleeve 185 rebounds, the negative pressure inside it causes the flushing liquid in the liquid storage cup 11 to enter the rubber sleeve 185 through the liquid inlet, the pumping channel 188, and the liquid inlet guide hole 187. Repeat the above actions to pump the flushing liquid in the liquid storage cup 11 out. When in use, first discharge the air in the pump body 18 until the flushing liquid flows out of the infusion tube 14 smoothly, and then connect the infusion tube 14 to the hose 2.

[0055] In this embodiment, the power assembly includes a rocker 19, a turntable 110, a rotor 12, a first bevel gear 17 and a second bevel gear 13; the turntable 110 is rotatably mounted on the liquid storage cup 11 through a bearing sleeve; the rotor 12 is fixed to the lower side of the turntable 110, and the lower end surface of the rotor 12 is in sliding contact with the upper end of the rubber sleeve 185; the lower end surface of the rotor 12 is set as an inclined surface; the rocker 19 is rotatably set on the housing 15; the first bevel gear 17 is fixedly mounted on the rocker 19, and the second bevel gear 13 is fixedly mounted on the bottom of the turntable 110 and meshes with the first bevel gear 17 for transmission; rotating the rocker 19 drives the first bevel gear 17 to rotate, so that the second bevel gear 13 drives the turntable 110 and the rotor 12 to rotate synchronously, and the lower end surface of the rotor 12 presses down the rubber sleeves 185 of multiple pump bodies 18 in sequence during the rotation process. The rubber sleeves 185 of the plurality of pump bodies 18 are pressed down and rebounded in sequence, so that the flushing liquid is continuously pumped into the patient's bladder.
