It should be noted that the portable pull ring can be directly arranged on the barrel body without arranging the drainage bag.
The working principle of the invention is as follows: respectively designing flow velocity regulators at the Y-shaped flushing pipe and the drainage pipe; the two flushing bags are identical and are used at the same time and are replaced at the same time, so that the two flushing bags are convenient to set and provide sufficient flushing liquid; the heating device is prepared and connected with a power supply. Preparing an external drainage tube extrusion device and externally connecting a power supply. The drainage tube squeezing device comprises a controller, an air pump, a tube belt, a pressure sensor and a deflation valve. The pressure sensor detects the pressure in the pipe belt, and the pipe belt is wound outside the rubber pipe and is used for extruding the rubber pipe. Specifically, the tube strip is communicated with the air outlet of the air pump, and when the air pump charges the tube strip, the volume of the tube strip expands and presses the rubber tube at the inner side of the tube strip. When the pressure value detected by the pressure sensor reaches the set pressure value, the air pump stops working. At this time, the air release valve discharges the air in the pipe belt, and the pipe belt is reduced in volume until the rubber pipe is not extruded any more. The bleed valve may be a controlled solenoid valve or may be provided with a vent that is always open. The exhaust port has a small flow area.
Thus, when the air pump is operated to inflate, the amount of air input into the tube band by the air pump exceeds the amount of air discharged from the air outlet, the air pressure in the tube band increases, the volume increases, and the rubber tube inside is pressed. When the air pump stops working, the pressure gas in the pipe belt is discharged through the air outlet, the air pressure is reduced, the volume is reduced until the pressure in the pipe belt is the same as the atmospheric pressure, and the rubber pipe at the inner side is not extruded any more. In the case that the air release valve is provided with an air outlet which is always opened, the pressure sensor can be omitted, the central processing unit can be simplified into a timing circuit, the on and off of the air pump switch can be controlled, and the air pump can be supplied with power regularly. Advantageously, the air pump switch is a time delay switch. For example, after triggering, the switch is turned off after a set period of time (e.g., one period of time within 10 seconds to 60 seconds), similar to the widely used voice-operated switches that control lighting in the corridor, but in the present invention, the air pump switch is triggered by a timing circuit. Advantageously, the drain tube squeezing device is provided with a mode selection switch.
The drain tube compression device has two modes of operation, a first mode of operation being a timed compression mode in which, for example, inflation compression is performed once an hour or other set number of times. The second operation mode is a repeated extrusion mode in which the air pump repeatedly inflates the tube band, and extrudes the drainage tube (e.g., rubber tube) until exiting the repeated extrusion mode. A detachable electronic scale is arranged below the liquid collecting barrel, and the alarm weight can be set. The drainage bag (also called a liquid collecting bag) is arranged in the liquid collector, and the liquid collecting bag can be reused or arranged to be disposable. The liquid barrel is provided with an integrated matched cover, the cover is provided with a water inlet and a water outlet, and a small water outlet cover is arranged at the water outlet. The side surface of the drainage bag is provided with a portable pull ring (which is convenient for pouring liquid). It should be noted that the portable pull ring can be directly arranged on the barrel body without arranging the drainage bag.
The bladder irrigation device can control the speed of liquid flowing into the bladder at any time; if the patient needs to intermittently rinse the bladder, two first flow regulators at the irrigation tube may be opened and the second flow regulator at the drain tube site closed. After the liquid flows into the bladder and is fully contacted with the bladder, the two first flow regulators at the flushing pipe are closed, the second flow regulator at the drainage pipe is opened, and the liquid in the bladder is discharged into the liquid collecting barrel. When the liquid collecting barrel for storing drainage liquid is replaced, the second flow speed regulator at the drainage tube is only required to be closed. It is possible to open or close the first flow rate regulator at the flushing pipe when the liquid collecting tank is replaced. If the illness state of the patient allows, an electric heating device can be externally connected. Such as a heated resistance wire or an electrically heated rod, is rinsed with a hot solution to reduce the occurrence of bladder cramps and discomfort to the patient. If there is active bleeding in the bladder, no flushing with hot solution is possible. A rubber tube portion of the timing squeeze drainage tube may be provided, for example, the rubber tube is squeezed once per hour. When the pipe is blocked, the rubber pipe can be continuously and repeatedly extruded until the drainage is smooth. For example, when the pipe is plugged, the rubber pipe is extruded once per minute. A detachable electronic scale is arranged below the liquid collecting barrel. The weight of the weighing scale can be set to be 6kg (the weight of the liquid collecting barrel is removed), and the weighing scale alarms when the liquid in the liquid collecting barrel reaches 6kg (namely, the liquid is about 6000 ml). Closing the flow speed regulator at the rubber tube, pulling the pull rings on two sides of the drainage bag (liquid collecting bag) by both hands, lifting the liquid collecting bag, opening the small cover at the water outlet, pouring out the liquid, and then installing the empty bag in the barrel to continuously collect the liquid. If the liquid collecting bag is disposable, when the weighing scale alarms, the liquid collecting bag is taken out, the liquid is poured out and discarded, and a new liquid collecting bag is replaced in the barrel.
Compared with the prior art, the invention has the following beneficial effects: the bladder irrigation device provided by the invention overcomes the defects of manpower and time waste of nursing staff and the like caused by inconvenient control of flow rate, inconvenient measurement, easy blockage of the front end of a urinary catheter and the like of the traditional bladder irrigation device.

The present invention is further illustrated by the following examples, which are not intended to be limiting, but any modifications, equivalents, improvements, etc. within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
As shown in fig. 1, the bladder irrigation device according to an embodiment of the present invention includes a three-chamber urinary catheter 4, and further includes an irrigation bag 1, a first flow regulator 2, a drain tube squeezing device 5, a second flow regulator 6, a liquid trap, an irrigation tube 8, and a drain tube 9.
The flushing pipe 8 is Y-shaped. The flushing pipe 8 comprises a flushing bag communicating pipe branch pipe I8.1, a flushing bag communicating pipe branch pipe II 8.2 and a three-cavity urinary pipe communicating pipe branch pipe 8.3. One end of the first flushing bag communicating pipe branch pipe 8.1 and one end of the second flushing bag communicating pipe branch pipe 8.2 are communicated with one end of the three-cavity urinary pipe communicating pipe branch pipe 8.3, and the other ends of the first flushing bag communicating pipe branch pipe 8.1 and the second flushing bag communicating pipe branch pipe 8.2 are respectively communicated with a flushing bag 1. The first flushing bag communicating pipe branch pipe 8.1 and the second flushing bag communicating pipe branch pipe 8.2 are respectively provided with a first flow speed regulator 2. The three-cavity urinary catheter communication branch pipe 8.3 is connected with a flushing drip pipe 4.1 of the three-cavity urinary catheter 4, one end (upper end in the figure) of a drainage pipe 9 is connected with a urinary catheter drainage pipe end 4.2 of the three-cavity urinary catheter 4, and the other end (lower end in the figure) of the drainage pipe 9 is communicated with a liquid trap. The drainage tube 9 is provided with a drainage tube extruding device 5 and a second flow regulator 6 from top to bottom. The draft tube pressing device 5 is arranged upstream of the second flow rate regulator 6.
In the illustrated embodiment, the other ends of the first flushing bag communicating pipe branch pipe 8.1 and the second flushing bag communicating pipe branch pipe 8.2 are respectively communicated with a flushing bag 1, and the two flushing bags 1 have the same structure; the three-cavity urinary catheter communication branch pipe 8.3 is also provided with a heating device 3; the heating device 3 is a heating resistance wire or a heating rod; the three-chamber urinary catheter 4 also comprises a catheter front end 4.3. The water bag is arranged at the right end of the front end 4.3 of the urinary catheter. The water injection pipe 4.4 is used for injecting water into the water sac, so that the water sac is inflated and fixed in the bladder, thereby positioning the three-cavity urinary catheter in the bladder and preventing the three-cavity urinary catheter from falling off. For example, the right side of the front end of the urinary catheter is provided with a water sac, and 10ml of sterile physiological saline is injected into the water sac through a water injection pipe 4.4, so that the three-cavity urinary catheter is fixed and prevented from slipping. And (3) discharging the sterile physiological saline, and taking down the three-cavity urinary catheter when the water bag contracts.
It will be appreciated that the catheter tip 4.3 communicates with the catheter drainage tip 4.2 to drain urine and irrigant from the bladder through the catheter drainage tip 4.2.
The drainage tube squeezing device 5 comprises a controller, an air pump, a tube belt, a pressure sensor and a deflation valve. The air pump is electrically connected with the signal output end of the controller. The pressure sensor is electrically connected with the signal input end of the controller, and is positioned in the pipe belt or communicated with the pipe belt. The pressure sensor detects the pressure within the tube band. The tube band is wound on the outer wall of the drainage tube 9 and is used for extruding the drainage tube 9.
The tube belt is communicated with the air outlet of the air pump, and when the air pump charges the tube belt, the volume of the tube belt expands and extrudes the drainage tube 9 at the inner side of the tube belt. When the pressure value detected by the pressure sensor reaches the set pressure value, the air pump stops working, the air release valve is arranged on the pipe belt, and the air in the pipe belt is discharged by the air release valve.
In an alternative embodiment, the air release valve is a solenoid valve, and the solenoid valve is electrically connected with the signal output end of the controller. The tube band is inflated and deflated by causing the solenoid valve to open and close at a set timing, thereby squeezing and releasing the drain tube 9. When the drainage tube is squeezed, the fluid in the drainage tube flows reversely, namely flows towards the urinary catheter, so that the blockage of the three-cavity urinary catheter is prevented. It will be appreciated that the timing of operation of the bleed valve is coordinated with the timing of operation of the air pump. When the air pump works, the air release valve is closed. After the air pump stops working, the air release valve is opened. Therefore, the repeated inflation and deflation of the tube belt are realized, and the drainage tube is repeatedly extruded, so that the drainage tube or the three-cavity urinary catheter is prevented from being blocked. For example, one anti-blocking operation may be performed every 5 minutes. Each anti-blocking operation included 0.5 minutes of air pump inflation and 0.5 minutes of air bleed.
In another embodiment, the purge valve is a vent that is always open. The exhaust port has a set flow area. It will be appreciated that the exhaust port has a small flow area. The flow area of the exhaust port is smaller than that of the pipe with the air inlet or the air outlet of the air pump. For example, the flow area of the exhaust port is set in the range of 0.1 square millimeters to 0.5 square millimeters. Or the flow area of the exhaust port is set such that: the time for which the air discharge is completed in the maximum inflation state to balance the internal and external air pressures is a set period of time, for example, in the range of 0.3 seconds to 1.0 seconds, more specifically, for example, 0.5 seconds. The maximum inflation state refers to a state that the air pump works to enable the pipe belt to be inflated with the most air in one anti-blockage operation period.
In an alternative embodiment, a rubber elastic balloon is provided on said drain tube 9. Advantageously, the rubber-elastic balloon is arranged in series on the drainage tube 9. The diameter of the rubber elastic air bag is larger than that of the drainage tube 9. For example, the maximum diameter of the rubber elastic balloon is set to be equal to or greater than three times the diameter of the drainage tube. The rubber elastic bladder is, for example, generally cylindrical or spindle-shaped in shape. The pipe strap is wound on the periphery of the rubber elastic air bag. For example, the tube band is spirally wound around the outer periphery of the rubber elastic balloon.
Under the condition that the air release valve is an air outlet which is always opened, the air release valve is fixedly connected to the rubber elastic air bag, and an air inlet (an opening communicated with the air pump) of the pipe belt is also fixedly connected to the rubber elastic air bag so as to prevent the pipe belt from falling off from the rubber elastic air bag. The structure is combined with the spiral arrangement of the pipe belt, so that the extrusion can be well realized, and the pipe belt can be prevented from falling off. More advantageously, a lubricant is provided on the outer periphery of the tube band, or between the tube band and the rubber elastic balloon, so as to reduce friction between the tube band and the rubber elastic balloon and prevent breakage of the tube band.
The bladder irrigation device further comprises an electronic scale 10. The liquid collector is arranged on the electronic scale 10, and an audible and visual alarm is connected to the electronic scale 10. The liquid collector is a disposable liquid collecting bag or a liquid collecting barrel. The liquid collector comprises a water inlet 7.1, a small water outlet cover 7.3, a water outlet 7.4, a barrel body 7.5 and a barrel body upper cover 7.6, wherein the barrel body upper cover 7.6 is buckled on the barrel body 7.5. The upper cover 7.6 of the barrel body is provided with a water inlet 7.1 and a water outlet 7.4, the lower end of the drainage tube 9 is connected with the water inlet 7.1, and the water outlet 7.4 is buckled with a small water outlet cover 7.3. A drainage bag is arranged in the barrel body 7.5, and a portable pull ring 7.2 is arranged on the drainage bag. It should be noted that the portable pull ring can be directly arranged on the barrel body without arranging the drainage bag.

As shown in fig. 1, the three-chamber urinary catheter 4 is a three-way tube, which connects the irrigation bag, the bladder and the fluid trap, respectively. The lower protruding part (water injection pipe 4.4, also called valve sleeve) is used for fixation. Specifically, as previously described, the water injection pipe 4.4 is connected to a water bladder or similar flexible container for support and fixation. For example, the three-chamber urinary catheter 4 is placed in a human body, 10ml of sterile physiological saline is injected from the water injection tube 4.4, and the inflated water sac is blocked in the bladder, so that the three-chamber urinary catheter 4 is prevented from falling off the human body.
After the Y-shaped flushing pipe and the three-cavity urinary pipe are connected and discharged, the speed of liquid dripped into the bladder is regulated by the first flow regulator 2, and whether the urinary pipe is blocked by blood clots and the like is judged by observing the speed of liquid dripped into the bladder and the speed of liquid discharged from the drainage tube 9. In order to prevent the blockage of the tube, the drainage tube extruding device 5 is powered on and placed at the rubber tube part of the drainage tube, and the drainage tube extruding device 5 is arranged to extrude the rubber tube at regular time. When the tube is plugged, the drainage tube extruding device 5 is arranged to continuously extrude the rubber tube part of the drainage tube, and pressure is applied to wash away the blood clot and other tissues to a position far away from the orifice of the urine tube, or the blood clot and other tissues are scattered into small blocks to be discharged from the drainage tube, so that liquid smoothly flows out of the drainage tube to the liquid collecting barrel.
The detachable electronic scale 10 is installed under the liquid collecting barrel, the alarm weight can be set, for example, the alarm weight is set to be 6kg (the weight of the liquid collecting barrel is removed), when the liquid in the liquid collecting barrel reaches 6kg (namely, the liquid is about 6000 ml), the weighing scale alarms, the second flow regulator 6 at the rubber tube is closed, the portable pull rings 7.2 at the two sides of the liquid collecting bag are pulled by two hands, the collecting bag is pulled, the small water outlet cover 7.3 is opened, the liquid can be poured out, then the empty bag is installed in the barrel, and the liquid is continuously collected. (if the weighing scale is disposable, when the weighing scale alarms, the liquid collecting bag is taken out, the liquid is poured out and discarded, and a new collecting bag is replaced in the barrel.)
In the clinical use process, if a patient needs to intermittently flush the bladder, the two first flow regulators 2 at the flushing pipe can be opened, the second flow regulator 6 at the drainage pipe position is closed, after the liquid flows into the bladder and is fully contacted with the bladder, the two first flow regulators 2 at the flushing pipe are closed, the second flow regulator 6 at the drainage pipe is opened, and the liquid in the bladder is discharged into the liquid collecting barrel, so that the invention can realize continuous bladder flushing and intermittent bladder flushing.
In the clinical use process, if the illness state of the patient is allowed (if active bleeding exists in the bladder, the patient can not be washed by using a hot solution), the heating device 3 can be externally connected, the occurrence of bladder spasm of the patient and discomfort of the patient are reduced, and the experience of the patient is improved.
