Fig. 1 is circuit connection diagram of the present utility model;
Fig. 2 is system structure sketch map of the present utility model;
Among the figure: 1. flushing liquor water bag, 2. heater, 3. temperature sensor, 4. gas-liquid separator, 5. pressure transducer, 6. first peristaltic pump, 7. second peristaltic pump, 8. turbidity detecting sensor.
The specific embodiment
Be described in further detail below in conjunction with 1 pair of the technical solution of the utility model of accompanying drawing:
As shown in Figure 1, the lower end of flushing liquor water bag is provided with heater, flushing liquor can be heated when flowing through this heater, clinical effectiveness confirms to heat effectively to reduce the generation of cystospasm to 20 ℃～30 ℃ normal saline flushing bladder, increase patient's comfort level, reduce complication, 35～37 ℃ is the optimum temperature of continuous bladder irrigation.The heater lower end is provided with temperature sensor, and temperature sensor is connected with the PLC Programmable Logic Controller by the A/D modular converter, and the PLC Programmable Logic Controller passes through D/A modular converter transmission of control signals to temperature control equipment simultaneously.When the temperature of flushing liquor was lower than 20 ℃～30 ℃, heater was heated to flushing liquor, and when temperature reached 35～37 ℃, heater was incubated flushing liquor, realized the closed loop control of temperature thus.
First peristaltic pump, second peristaltic pump, pressure transducer, bladder link to each other by the tube for transfusion that a four-way connects.Pass through control second peristaltic pump before the flushing beginning, make the blowdown port shutdown, flushing liquor arrives bladder through first peristaltic pump after flowing out heater, the reading of pressure transducer will increase gradually this moment, the pressure detecting data are by A/D modular converter input PLC Programmable Logic Controller, controller is controlled the rotation of first peristaltic pump by D/A modular converter transmission of control signals to the first peristaltic pump, reduces the flow velocity of flushing liquor.When pressure transducer finds that intravesical pressure reaches default maximum, the PLC Programmable Logic Controller is by D/A modular converter transmission of control signals to the first peristaltic pump, second peristaltic pump, make flushing liquor flow into port shutdown and the blowdown port is opened, the process that the simulation human body natural urinates.Detection to instant pressure is controlled the rotating speed of first peristaltic pump, second peristaltic pump according to pressure transducer, realizes the closed loop control of pressure thus.Pressure transducer also can be used for continuing detection bladder pressure (intra-abdominal pressure).
The physiological function of bladder is to store and drain urine.Long term indwelling catheter and spinal nerves damage can cause the disorder of bladder physiological function.This utility model is by the programmed settings in advance of PLC Programmable Logic Controller, can be by the corresponding actions of control first peristaltic pump, second peristaltic pump, make intravesical pressure remain on a fixed numeric values, thereby simulation bladder physiological function is tempered maintenance bladder normal physiological function.Bladder irrigation is one of measure of prevention and control indwelling catheter patient urinary tract infection, the principle of bladder irrigation is to utilize the effect of pressure that a certain amount of sterile liquid is injected bladder by urinary catheter, this therapeutic instrument is by the control to the peristaltic pump rotating speed, can strengthen the speed of flushing liquor perfusion, go out clot and foreign body fast, reach cleaning bladder, dilution urine, scavenger precipitation thing, prevent that catheter from stopping up, keeping the unobstructed purpose of urine drainage.
Be provided with the turbidity detecting sensor at the sewage draining exit place, this sensor can be monitored the variation that urine in the discharge liquor contains blood volume in real time, Monitoring Data is immediately passed to the PLC Programmable Logic Controller by the A/D modular converter, by predefined program, different turbidity is changed, monitor in real time, and in case of emergency, make corresponding status alarm.
