Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, specifically an adjustable low-pressure bladder irrigator. Background Art

[0002] Bladder irrigation is a method that uses a catheter to pour a solution into the bladder and then drains the poured liquid by means of the siphon principle. It is generally divided into a closed irrigation method and an open irrigation method. Closed irrigation method: That is, infusion bottle irrigation. The irrigation liquid medicine is in the infusion bottle, which is hung on the infusion rack beside the bed. The height of the bottle is about 1 meter from the patient's pelvis. The lower end of the infusion tube is connected to a three-way valve, which is then respectively connected to the urinary catheter and the drainage tube. The height of the three-way valve is slightly lower than the pubic symphysis plane to facilitate the emptying of the liquid in the bladder. During irrigation, first clamp the drainage tube, and infuse the irrigation liquid at a speed of 60 drops per minute. After injecting 100 ml each time, clamp the infusion tube and open the drainage tube. The irrigation liquid flows out. Repeat this process 3 - 4 times each time. Open irrigation method: Use a bladder irrigator or a large syringe. Each time during irrigation, first separate the connector of the indwelling urinary catheter or the bladder fistula catheter. The distal drainage tube connector is wrapped with a sterile gauze and placed aside. After disinfecting the end of the urinary catheter or the bladder fistula catheter, hold it with a sterile gauze. Connect the irrigator filled with the irrigation liquid to the end of the catheter, slowly inject the irrigation liquid, and then let it flow out naturally or slowly suck it out. Repeat this process until the outflow liquid is clear. After the irrigation is completed, flush the distal drainage tube once, and then connect the urinary catheter or the bladder fistula to continue drainage.

[0003] When injecting with a large syringe, it requires medical staff to manually control the speed. Most ordinary bladder irrigators cannot display the hydraulic pressure. It is difficult for medical staff to control the injection rate according to the hydraulic pressure, and it is easy to cause too high hydraulic pressure or instantaneous impact of the liquid, which is likely to cause bladder damage and patient discomfort.

[0044] In the present Embodiment 1: The fluid - passing docking mechanism includes a first liquid - guiding hose 501, a second liquid - guiding hose 502, a syringe plunger 503, a first urinary catheter adapter 504, and an anti - detachment ring 505. The first liquid - guiding hose 501 is fixedly connected between the fourth flow - through hard tube 401 and the first flow - through hard tube 101. The second liquid - guiding hose 502 is fixedly connected between the third flow - through hard tube 301 and the second flow - through hard tube 201. The syringe plunger 503 is fixedly connected to one end of the second flow - through hard tube 201 away from the second liquid - guiding hose 502. The first urinary catheter adapter 504 is fixedly connected to one end of the first flow - through hard tube 101 away from the first liquid - guiding hose 501. The anti - detachment ring 505 is integrally arranged on the surface of the first urinary catheter adapter 504, and the shape of the first urinary catheter adapter 504 is tower - shaped. During use, first, the second disassembly and assembly head 408 is snap - connected to the surface of the fourth flow - through hard tube 401, and the first disassembly and assembly head 305 is snap - connected to the surface of the third flow - through hard tube 301;

[0045] Then, air is injected into the sealing tank 203 through a syringe. The more gas there is inside the sealing tank 203, the lower the inflation effect when the buffer airbag 205 expands, and the lower the buffering effect. By adjusting the air volume inside the sealing tank 203, the inflation effect of the buffer airbag 205 can be adjusted. After filling with air, the sealing cover 208 is closed;

[0046] Then, the pressurizing airbag 413 is continuously pressed to inflate the air storage box 410. When inflating, the pressing of the pressurizing airbag 413 will open the exhaust check valve 414 and close the intake check valve 415. The gas inside the pressurizing airbag 413 is pressed into the air storage box 410 through the second air - guiding hose 411. When the pressurizing airbag 413 is released, it will expand and restore. The exhaust check valve 414 closes, and the intake check valve 415 opens. The pressurizing airbag 413 inhales external air into it. By repeatedly pressing the pressurizing airbag 413, a certain amount of high - pressure gas is stored inside the air storage box 410;

[0047] Then, a new syringe is replaced, and it is filled with rinsing liquid. Then the syringe is docked with the syringe plunger 503, and the syringe is squeezed to drain the liquid, so that the air inside the device is discharged. Then the first urinary catheter adapter 504 is inserted into the urinary catheter for pushing and injecting for cleaning;

[0048] During cleaning, the hydraulic pressure will squeeze the deformation film 107 to deform. The greater the hydraulic pressure, the greater the deformation degree of the deformation film 107. The hydraulic oil inside the liquid storage cavity 103 is pressed and enters the liquid column capillary channel 106. The greater the hydraulic pressure, the smaller the space inside the liquid storage cavity 103, and the deeper the liquid column entering the liquid column capillary channel 106. By observing the size and change speed of the liquid column, the size and change speed of the hydraulic pressure can be understood;

[0049] If the hydraulic pressure increases instantaneously, the liquid will squeeze the buffer airbag 205 to expand, so that the pressure can be released and the instantaneous increase of hydraulic pressure can be avoided. If the hydraulic pressure decreases instantaneously, the buffer airbag 205 will contract, and the cleaning liquid inside it will be replenished into the second flow hard pipe 201 to avoid the instantaneous decrease of hydraulic pressure;

[0050] When the hydraulic pressure is too high, the rubber membrane 405 will be compressed and expanded to a certain extent. The expansion of the rubber membrane 405 will push the rising slide plate 407 to slide upward, and at the same time the spring will contract until the switch hole 422 slides into the space between the first sliding seal ring 418 and the second sliding seal ring 419. The high-pressure gas inside the air storage box 410 will be discharged into the first air guide hose 309 through the exhaust groove 421, and then enter the inside of the first disassembly and assembly head 305. Since the pressure relief capillary hole 306 is too small, it is difficult for the high-pressure gas to be discharged instantaneously, so that the closed-circuit piston 307 can be squeezed to slide. The sliding of the closed-circuit piston 307 will squeeze the rubber sleeve 303 to contract. After the rubber sleeve 303 contracts, the flow rate passing through it will decrease or even close, and the hydraulic pressure behind it will decrease, thus avoiding the patient from being affected by too high hydraulic pressure and ensuring that the medical staff can adjust in time. After the pressure adjustment hydraulic pressure becomes smaller, the rubber membrane 405 is compressed and lowered and contracts, and the spring squeezes the rising slide plate 407 to slide back to its original position, and the lifting slide column 416 is driven to slide, so that the switch hole 422 slides out, the air storage box 410 is closed, and after there is no gas supplement, the gas inside the first disassembly and assembly head 305 leaks out from the pressure relief capillary hole 306, and the rubber sleeve 303 rebounds and restores, and the closed-circuit piston 307 is squeezed back to its original position.

[0051] In the second embodiment: The flow-through docking mechanism includes a first liquid guide hose 501, a second liquid guide hose 502, a needle bolt 503, a second urinary catheter adapter 506 and an anti-detachment strip 507. The first liquid guide hose 501 is fixedly connected between the fourth flow hard pipe 401 and the first flow hard pipe 101. The second liquid guide hose 502 is fixedly connected between the third flow hard pipe 301 and the second flow hard pipe 201. The needle bolt 503 is fixedly connected to one end of the second flow hard pipe 201 away from the second liquid guide hose 502. The second urinary catheter adapter 506 is fixedly connected to one end of the first flow hard pipe 101 away from the first liquid guide hose 501. The anti-detachment strip 507 is integrally arranged on the surface of the second urinary catheter adapter 506, and the shape of the second urinary catheter adapter 506 is conical, and the anti-detachment strip 507 is a spiral anti-detachment strip. When in use, first snap the second disassembly and assembly head 408 on the surface of the fourth flow hard pipe 401, and snap the first disassembly and assembly head 305 on the surface of the third flow hard pipe 301;

[0052] Then inject air into the sealing tank 203 through a syringe. The more gas is inside the sealing tank 203, the lower the expansion effect of the buffer airbag 205 when it expands, and the lower the buffer effect. By adjusting the air volume inside the sealing tank 203, the expansion effect of the buffer airbag 205 can be adjusted. After filling with air, close the sealing cover 208;

[0053] Then, the pressurized airbag 413 is continuously pressed to inflate the interior of the air storage box 410. During inflation, pressing the pressurized airbag 413 will open the exhaust check valve 414 and close the intake check valve 415. The gas inside the pressurized airbag 413 is pressed into the interior of the air storage box 410 through the second air guide hose 411. When the pressurized airbag 413 is released, it will expand and recover, the exhaust check valve 414 will close, the intake check valve 415 will open, and the pressurized airbag 413 will suck the external air into the interior. Repeatedly pressing the pressurized airbag 413 will store a certain amount of high-pressure gas inside the air storage box 410.

[0054] Then replace the new syringe, fill it with flushing liquid, and then dock the syringe with the needle plug 503, squeeze the syringe to drain the liquid so that the air inside the device is expelled, and then insert the second catheter plug 506 into the catheter to perform push injection cleaning;

[0055] During cleaning, the hydraulic pressure will squeeze the deformable membrane 107 and deform it. The greater the hydraulic pressure, the greater the deformation of the deformable membrane 107. The hydraulic oil inside the liquid storage chamber 103 will enter the liquid column capillary channel 106 under pressure. The greater the hydraulic pressure, the smaller the space inside the liquid storage chamber 103, and the deeper the liquid column entering the liquid column capillary channel 106. By observing the size and change speed of the liquid column, the size and change speed of the hydraulic pressure can be understood.

[0056] If the hydraulic pressure increases instantaneously, the liquid will squeeze the buffer airbag 205 to expand, thereby releasing the pressure and preventing the hydraulic pressure from increasing instantaneously. If the hydraulic pressure decreases instantaneously, the buffer airbag 205 will contract, and the cleaning liquid inside it will be replenished into the second circulation rigid tube 201, thus preventing the hydraulic pressure from decreasing instantaneously.

[0057] When the hydraulic pressure is too high, the rubber membrane 405 will be compressed and expanded to a certain extent. The expansion of the rubber membrane 405 will push the expansion plate 407 to slide up, and the spring will shrink until the switch hole 422 slides into the space between the first sliding seal ring 418 and the second sliding seal ring 419. The high-pressure gas inside the air storage box 410 will be discharged into the first air guide hose 309 through the exhaust groove 421, and then enter the first disassembly head 305. Since the pressure relief capillary hole 306 is too small, the high-pressure gas is difficult to be discharged instantly, thereby squeezing the closing piston 307 to slide. The sliding of the closing piston 307 will squeeze the rubber sleeve 309. 03 contracts. After the rubber sleeve 303 contracts, the flow passing through it is reduced or even closed, and the hydraulic pressure behind it is reduced, thereby preventing the patient from being subjected to excessive hydraulic pressure and ensuring that medical staff can make timely adjustments. After the pressure-adjusted hydraulic pressure becomes smaller, the rubber membrane 405 is compressed and contracted, and the spring squeezes the sliding plate 407 to slide and reset, and the lifting slide 416 is driven to slide, causing the switch hole 422 to slide out, and the gas storage box 410 is closed. After there is no gas to be replenished, the internal gas of the first disassembly and assembly head 305 leaks out from the pressure relief capillary hole 306, the rubber sleeve 303 rebounds and recovers, and the closed-circuit piston 307 is squeezed and reset.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
