Description

An automatic bladder irrigator

technical field

The invention belongs to the field of medical devices, in particular to an automatic bladder flusher.

Background technique

Bladder irrigation is to use a catheter to pour the solution into the bladder, and then drain the poured liquid. Its purpose is to keep the urine drainage smooth for patients with indwelling catheters; remove blood clots in the bladder , mucus, bacteria and other foreign bodies to prevent infection.

At present, there are two commonly used methods for bladder flushing, closed flushing method: flushing with infusion bottles, flushing the liquid medicine or in the infusion bottles, and hanging on the infusion stand beside the bed. Connect the tee, and then connect with the urinary catheter and the drainage tube respectively. The height of the tee is slightly lower than the pubic symphysis plane, so as to facilitate the emptying of fluid in the bladder. When flushing, clamp the drainage tube first, and infuse the flushing solution at a rate of 60 drops/min. After injecting 100ml each time, clamp the infusion tube and open the drainage tube, and the flushing fluid will flow out. Repeat this process for 3-4 times each time. Open flushing method: use a bladder flusher or a large syringe, separate the connector of the indwelling urinary catheter or cystostomy tube each time, wrap the distal drainage tube connector with sterile gauze and put it aside, the urinary catheter or bladder After the end of the ostomy catheter is sterilized, it is held with sterile gauze, and the irrigator that has absorbed the irrigating fluid is connected to the end of the catheter, and the irrigating fluid is slowly injected, and then flows out naturally or slowly sucked out. Repeat this until the effluent is clear. After flushing, rinse the distal drainage tube once, and then connect the urinary catheter or cystostomy to continue drainage.

For the prior art, if there is blood clot blockage in the manual bladder flushing to cause urine retention, only repeated manual bladder flushing is performed, and the manual bladder flushing is easy to cause the staff to grasp the strength poorly and the suction is unsuccessful; the syringe and urine The connection at the water outlet of the pipe is not tight, causing urine to splash and cause pollution.

Contents of the invention

Aiming at the problem in the prior art that manual bladder flushing workers do not master the force and cause unsuccessful suction, the present invention provides an automatic bladder flusher, the purpose of which is to make the process of bladder flushing and suction liquid go smoothly, avoiding Many inconveniences such as failure of suction due to poor grasp of strength during manual bladder irrigation, and blisters caused by repeated suction by the staff.

The technical scheme that the present invention adopts is as follows:

An automatic bladder irrigator, comprising a housing, the housing is provided with a water inlet, the housing is provided with a bladder tube access groove, the housing is provided with a waste liquid outlet, and the water inlet , The bladder tube access groove and the waste liquid outlet are connected through a conduit, the conduit is located inside the casing, the water inlet is provided with a flushing pump, and the waste liquid outlet is provided with a water suction pump.

With this solution, by setting the flushing pump at the water inlet, the normal saline can be sucked into the bladder through the machine and the catheter through the set water absorption. According to the set time, the flushing pump will automatically suck out the normal saline after a few seconds. The waste liquid discharge port is discharged until the blood clot is completely sucked out. It avoids various inconveniences such as unsuccessful suction due to poor grasp of strength during manual bladder flushing, and blisters caused by repeated suction by the staff.

Wherein, the water inlet is provided with a filter screen.

With this solution, setting the filter screen through the water inlet port can effectively block most of the impurities and avoid the infection caused by the entry of impurities.

Wherein, the conduit is a three-way conduit.

With this solution, the water inlet, the bladder tube access tank and the waste liquid discharge port adopt an integral molding process. One tube connects the three tube ports, and there is no gap in the connection part, and the liquid medicine will not leak.

Wherein, the three-way conduit includes a pipe connected to the water inlet and the other two pipes, a protrusion is provided at one end of the water inlet connecting pipe, and the protrusion is located on one side of the other two pipes.

Adopting this scheme, by setting a protrusion at the bottom leading to the water inlet at the confluence of the three pipelines, it can prevent the waste water from flowing into the side of the water inlet by inertia when the suction pump is sucking waste water, and add it to the patient in the next flush. The previous waste water will be brought into the liquid medicine, which will lead to infection. After setting the protrusion, it will not affect the addition of the liquid medicine. Even if a small part of the liquid medicine is blocked by the protrusion at one end of the water inlet when adding it, it will not affect the whole. As a result, when the waste water is sucked by the suction pump, the waste water has only a small amount of kinetic energy when it is sucked into the confluence of the three pipes, and the protrusion can also block most of the waste water from entering the side of the water inlet.

Wherein, the other end of the bladder tube access groove is connected with a rubber tube, and the shape of the rubber tube is wide-mouthed.

Adopting this scheme, the shape of the rubber tube is set to be wide-mouthed, and the opening becomes larger as it goes outward, so that the catheter can be slowly inserted into the rubber tube, and the catheter can be easily inserted due to the large opening at the end of the rubber tube. When the urinary catheter enters the rubber tube, the cross-section matches the cross-sectional size of the urinary catheter, and the catheter continues to be squeezed until it stops moving, which prevents the connection between the rubber tube and the urinary catheter from being airtight , the liquid is splashed outside the device to pollute the environment.

Wherein, the rubber tube is provided with equally spaced annular grooves.

With this scheme, when the rubber tube and the catheter are fixed in place, the rubber tube is continuously folded back according to the equal intervals of the annular grooves set on the rubber tube, because the rubber tube is an elastic material, and the rubber tube is in a tight state when it is continuously folded back. This makes the rubber tube firmly cover the urinary catheter, reduces the gap between the rubber tube and the urinary catheter as much as possible, and avoids splashing of liquid.

Wherein, two left and right baffles are arranged in the bladder tube access groove, and the combined size of the two baffles matches the size of the bottom of the bladder tube access groove, and the combined size of the two baffles is The shape matches the shape of the bottom of the bladder tube access groove. The spring is connected to the baffle, and the other end of the spring is connected to the side wall of the bladder tube access groove. A stay cord is respectively connected, and the other end of the stay cord passes through the side wall of the bladder tube access groove.

This scheme is adopted, because the suction of the water suction pump is greater than the gravity of the waste water when the water suction pump is sucking waste water, the waste water can only be sucked out, but there is a certain height difference between the bladder tube access tank and the waste water outlet, and the water suction pump is located in the bladder when it stops. The waste water between the tube access tank and the waste water discharge outlet will fall into the place before the suction due to gravity, which will lead to unclean flushing and affect the effect. By setting two baffles at the bottom of the bladder tube access tank, The two baffles have the same size and shape and are symmetrical to each other. The baffle is hingedly connected to the side wall of the bladder tube access groove. One end of the spring is connected to the baffle, and the other end of the spring is connected to the side of the bladder tube access groove. On the wall, it is connected by welding, and a small ring is welded above the end of the baffle, and the small ring above the end of the baffle is connected with a pull rope, and the other end of the pull rope runs through the side wall of the bladder tube access groove and extends to external. When the flushing pump is activated, the pull cord is pulled, and the baffle is pulled up, and the incoming saline flows smoothly to the patient. When the suction pump is activated, the pull cord is first pulled, and then the pull cord is no longer pulled, and the baffle is under the momentum of the waste water. In the open state, because the elastic force of the spring is less than the momentum of the waste water, when the suction pump is stopped, the waste water will fall into the patient's urinary catheter under the action of gravity, causing infection. But without the impulsive force of the waste water, the baffle will be closed under the elastic force of the spring, and the waste water will be blocked in the bladder tube access tank, and finally eliminated through treatment, which solves the problem of waste water backflow and infection.

Wherein, a rubber ring is arranged on the inner side of the bladder tube access groove where the pull cord penetrates.

With this scheme, since the pull rope and the through opening cannot be in a completely sealed state, it will cause waste water to flow out from the gap and cause pollution. By setting the rubber ring inside the through part and through the viscous connection, the pull rope will pass through the through opening. It is necessary to squeeze the rubber ring to wear it out. During the extrusion process, the rubber ring deforms and fills the gaps through deformation to solve the problem of wastewater flowing out.

Wherein, the drawstring is connected with a ring at one end outside the bladder tube access groove.

With this solution, the drawstring is provided with a ring at the end of the bladder tube access groove, and the drawstring is tied to the ring, which can save effort when stretching the drawstring, and the radius of the ring is larger than that of the bladder tube. The radius of the through opening in the groove prevents the stay cord from falling into the bladder tube access groove.

Wherein, a universal wheel is connected to the lower part of the housing, and a braking device is arranged on the universal wheel.

Adopting this scheme, the device can be moved conveniently by setting the universal wheel, and the brake device can be set on the universal wheel to prevent the device from slipping during operation and causing poor effect.

In summary, owing to adopting above-mentioned technical scheme, the beneficial effect of the present invention is:

1. By setting the flushing pump at the water inlet, the normal saline can be sucked into the bladder through the machine and the catheter through the set water absorption. According to the set time, the flushing pump will automatically suck out the normal saline from the waste liquid after a few seconds. The outlet is discharged until the blood clot is completely sucked out. It avoids various inconveniences such as unsuccessful suction due to poor grasp of strength during manual bladder flushing, and blisters caused by repeated suction by the staff.

2. Setting the filter screen through the water inlet port can effectively block most impurities and avoid infection caused by impurities entering.

3. The water inlet, the bladder tube access tank and the waste liquid discharge port adopt an integral molding process. One tube connects the three tube ports. There is no gap in the connection part, and the liquid medicine will not leak.

4. By setting a protrusion at the bottom leading to the water inlet at the confluence of the three pipelines, it can prevent the waste water from flowing into the side of the water inlet by inertia when the water suction pump is sucking waste water. Bring in the waste water from the last time, which will lead to infection. After setting the protrusion, it will not affect the addition of the medicine. Even if a small part of the medicine is blocked by the protrusion at the end of the water inlet when it is added, it will not affect the overall effect. When When the water suction pump absorbs waste water, it only has a small amount of kinetic energy when the waste water is sucked into the confluence of the three pipelines, and the protrusion can also block most of the waste water from entering the side of the water inlet.

5. The shape of the rubber tube is set to a wide-mouth type, and the opening becomes larger as it goes outward, so that the catheter can be slowly inserted into the rubber tube. Due to the large opening at the end of the rubber tube, the catheter can easily enter. When the catheter enters When the cross-section of the rubber tube matches the size of the cross-section of the catheter, the catheter continues to be squeezed until it stops moving. This prevents the connection between the rubber tube and the catheter from being leaky and liquid splash Spray outside the device and pollute the environment.

6. When the rubber tube and the urinary catheter are fixed in place, they should be folded back and forth according to the scale lines set on the rubber tube at equal intervals. Because the rubber tube is made of elastic material, the rubber tube is in a tight state by continuous folding, which makes the rubber tube Tightly cover the urinary catheter, reducing the gap between the rubber tube and the urinary catheter as much as possible, and avoiding the splash of liquid.

7. Two left and right baffles are arranged in the access groove of the bladder tube. The matching size of the two baffles matches the size of the bottom of the bladder tube access groove, and the shape of the two baffles matches the shape of the bladder tube. The shape of the bottom of the tube access groove matches, the spring is connected to the baffle, and the other end of the spring is connected to the side wall of the bladder tube access groove, and a pull cord is connected above the end of the baffle. The other end of the drawstring runs through the side wall of the bladder tube access groove to prevent backflow of waste water and cause infection.

8. Since the pull rope and the through opening cannot be in a completely sealed state, it will cause waste water to flow out from the gap and cause pollution. By setting the rubber ring inside the through part and through the viscous connection, the pull rope must pass through the through opening. The rubber ring can only be worn out by squeezing the rubber ring. During the extrusion process, the rubber ring is deformed, and the gap is filled through the deformation to solve the problem of wastewater flowing out.

9. By setting a ring at the end of the drawstring outside the bladder tube access groove, and the drawstring is tied to the ring, it can save more effort when stretching the drawstring, and the radius of the ring is larger than that of the bladder tube access The radius of the through opening in the groove prevents the stay cord from falling into the bladder tube access groove.

10. The movement of the device can be facilitated by setting the universal wheel, and setting the brake device on the universal wheel can prevent the poor effect caused by the sliding of the device during operation.

The water inlet 2 inside the housing 1, the bladder tube access groove 4, and the inside of the waste liquid outlet 3 are connected through a conduit 7, and an integrated molding process is adopted. By setting the flushing pump 5 at the water inlet 2, the water inlet 2 can be set With a good water absorption capacity, the physiological saline is absorbed and pushed into the bladder through the machine and the catheter. According to the set time, the flushing pump 5 will automatically suck out the normal saline after a few seconds and discharge it from the waste liquid outlet until the blood clot is completely sucked out. It avoids various inconveniences such as failure of suction caused by poor grasp of strength during manual bladder irrigation, and repeated suction of the staff, which causes hand wear and blisters and other inconveniences. The upper part of the bladder tube access groove 4 is provided with an exhaust port 15 to prevent internal factors The pressure problem affects the operation, which belongs to the prior art.

Preferably, the water inlet 2 is provided with a filter.

The reverse osmosis membrane is set on the filter net, and the membrane pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water.

Preferably, the conduit 7 is a three-way conduit.

Preferably, the three-way conduit includes a pipe connected to the water inlet 2 and the remaining two pipes, a protrusion 13 is provided at one end of the pipe connected to the water inlet 2, and the protrusion 13 is located on one side of the remaining two pipes .

One end of the pipe connected to the water inlet 2 is provided with a protrusion 13. The position of the protrusion 13 is near the confluence of the three pipes, which can prevent the waste water from flowing into the side of the water inlet 2 by inertia when the water suction pump 6 sucks waste water. The waste water from the last time will be brought in when adding the liquid medicine to the patient next time, which will cause infection. After the protrusion 13 is set, the addition of the liquid medicine will not be affected, even if a small part of the liquid medicine is blocked by the protrusion 13 at the water inlet when adding One end of 2 will not affect the overall effect. When the water suction pump 6 sucks waste water, only a small amount of kinetic energy is provided when the waste water is sucked into the confluence of the three pipelines. The protrusion 13 can also stop most of the waste water from entering the side of the water inlet 2.

Preferably, the other end of the bladder tube access groove 4 is connected with a rubber tube 8, and the shape of the rubber tube 8 is wide-mouthed.

The shape of the rubber tube 8 is set to a wide-mouth type, and the more the opening is larger, the catheter can be slowly inserted into the rubber tube 8, and the catheter can easily enter due to the large opening at the end of the rubber tube 8. When the tube enters the rubber tube 8, the cross-section matches the size of the cross-section of the catheter, and the catheter continues to squeeze inward until it stops moving, which prevents the connection between the rubber tube 8 and the catheter. If it is not airtight, the liquid will splash out of the device and pollute the environment.

Preferably, the rubber tube 8 is provided with equally spaced annular grooves 9 .

When the rubber tube 8 and the urinary catheter are fixed in place, the rubber tube 8 is constantly folded back according to the equally spaced annular grooves 9 provided on the rubber tube 8, because the rubber tube 8 is an elastic material, and the rubber tube 8 is in a tight state when it is continuously folded back.

Pull cords 12 are respectively connected above the mating sides of the two baffles 10 , and the other end of the draw cords runs through the side wall of the bladder tube access groove 4 .

Because the suction of water suction pump 6 when absorbing waste water will be greater than the gravity waste water of waste water just can be sucked out, but bladder tube access groove 4 and waste liquid outlet 3 have certain height difference, and water suction pump 6 is then positioned at stop when stopping. The waste water between the bladder tube access tank 4 and the waste liquid outlet 3 will fall into the place before the suction due to gravity, which will cause unclean flushing and affect the effect. Block baffle 10, two baffles 10 have the same size and shape and are symmetrical to each other, baffle 10 is hingedly connected with the side wall in bladder tube access groove 4, one end of spring 11 is connected on the baffle 10, spring 11 The other end of the bladder tube is connected to the side wall of the bladder tube access groove 4, and is connected by welding. A small ring is welded above the end of the baffle plate 10, and the small ring above the end of the baffle plate is connected with a pull cord 12. The other end of the rope 12 runs through the side wall of the bladder tube access groove 4 and extends to the outside. Pull the stay cord 12 when starting the flushing pump 5, and the baffle plate 10 is pulled up, and the salt water that enters leads to the patient smoothly. 10 is in the open state under the impulsive force of waste water, because the elastic force of spring 11 is less than the impulsive force of waste water, when stopping suction pump 6, waste water will fall in the patient's urinary catheter under the effect of gravity, cause infection. But without the momentum of the waste water, the baffle plate 10 will be in a closed state under the elastic force of the spring 11, and the waste water will be blocked in the bladder tube access tank 4, and finally eliminated through treatment, which solves the problem of waste water backflow and infection , wherein, the outside of the spring is wrapped with an anti-rust film, and the two ends of the anti-rust film are fixedly connected with the wall of the bladder tube access groove 4.

Preferably, a rubber ring is provided on the inner side of the bladder tube access groove 4 where the pull cord 12 penetrates.

It is impossible for the stay cord 12 and the through opening to be in a completely sealed state, which will cause waste water to flow out from the gap and cause pollution. By arranging a rubber ring on the inside of the penetrating part and connecting it viscously, the stay cord 12 must be squeezed out when passing through the through opening. The rubber ring can only be worn out. During the extrusion process, the rubber ring is deformed, and the gap is filled through the deformation to solve the problem of wastewater outflow.

Preferably, one end of the drawstring 12 outside the bladder tube access groove 4 is connected with a ring.
