Preparing an external drainage tube extruding device and an external power supply. The utility model provides a drainage tube extrusion device includes controller, air pump, pipe area, pressure sensor and bleed valve. The pressure sensor detects the pressure in the pipe belt, and the pipe belt is wound outside the rubber pipe and used for extruding the rubber pipe. Specifically, the tube band is communicated with an air outlet of the air pump, and when the air pump inflates the tube band, the volume of the tube band expands and the rubber tube on the inner side of the tube band is extruded. And when the pressure value detected by the pressure sensor reaches the set pressure value, the air pump stops working. At the moment, the air release valve discharges the air in the pipe belt, and the volume of the pipe belt is reduced until the rubber pipe is not squeezed any more. The bleed valve may be a controlled solenoid valve or may be arranged to have an exhaust port that is always open. The exhaust port has a small flow area.

Therefore, when the air pump works and inflates, the air quantity input into the tube belt by the air pump exceeds the air quantity discharged from the air outlet, the air pressure in the tube belt is increased, the volume is increased, and the rubber tube on the inner side is extruded. When the air pump stops working, the pressure gas in the pipe belt is discharged through the exhaust port, 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 on 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, and the central processing unit can be simplified into a timing circuit for controlling the on and off of the air pump switch to supply power to the air pump at regular time. Advantageously, the air pump switch is a time delay switch. For example, after triggering, the switch is turned off after a set time period of operation (e.g., one time period within 10 seconds to 60 seconds), similar to the widely used voice operated switch for controlling lighting in a corridor, however, in the present invention, the air pump switch is triggered by the timing circuit. Advantageously, the drain squeezing means is provided with a mode selection switch.

The drain extrusion device has two modes of operation, the first mode of operation being a timed extrusion mode in which, for example, one or other set number of air extrusions is inflated per hour. The second mode of operation is a repetitive squeeze mode in which the air pump repeatedly inflates the tube strip, squeezing the drainage tube (e.g., rubber tube) until exiting the repetitive squeeze mode. A detachable electronic scale is arranged below the liquid collecting barrel, and the alarm weight can be set. The inside of the liquid collector is provided with a drainage bag (also called a liquid collection bag), and the liquid collection bag can be repeatedly used and can also be set to be disposable. The liquid barrel is provided with an integrated matched cover, a water inlet and a water outlet are arranged on the cover, and a small water outlet cover is arranged at the water outlet. The side 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 of the utility model can control the speed of the liquid flowing into the bladder at any time; if the patient needs to intermittently irrigate the bladder, the two first flow regulators at the irrigation tube may be opened and the second flow regulator at the drain site may be closed. After the liquid flows into the bladder and is fully contacted with the bladder, the two first flow rate regulators at the position of the flushing pipe are closed, the second flow rate regulator at the position of 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. When the liquid collecting barrel is replaced, the first flow speed regulator at the position of the flushing pipe can be opened or closed. If the patient's condition permits, an external electric heating device can be connected. Such as a heated resistance wire or an electrically heated rod, to be flushed with a hot solution, thereby reducing the occurrence of bladder spasms and discomfort to the patient. If there is active bleeding in the bladder, it cannot be flushed with hot solution. The rubber tube portion of the drainage tube may be set to be pressed at regular times, for example, once per hour. When the pipe is blocked, the rubber pipe can be continuously and repeatedly extruded until the drainage is smooth. For example, in plugging a tube, the rubber tube is squeezed once per minute. A detachable electronic scale is arranged below the liquid collecting barrel. An alarm weight may be set, for example an alarm weight of 6kg (excluding the weight of the drum itself), and when the liquid in the drum reaches 6kg (i.e. about 6000ml), the scale alarms. The flow rate regulator at the position of the rubber tube is closed, the two hand-held pull rings at the two sides of the drainage bag (liquid collection bag) are lifted by two hands, the liquid collection bag is lifted, the small cover at the water outlet 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 liquid collecting bag is disposable, when the weighing scale gives an alarm, the liquid collecting bag is taken out, the liquid is poured out and discarded, and the barrel is internally replaced by a new liquid collecting bag.

The water sac is arranged at the right end of the front end 4.3 of the ureter. Water is injected into the water sac through the water injection pipe 4.4, so that the water sac is expanded and fixed in the bladder, the three-cavity urinary catheter is positioned in the bladder, and the three-cavity urinary catheter is prevented from falling off. For example, the right side of the front end of the urinary catheter is provided with a water sac, 10ml of sterile normal saline is injected into the water sac through a water injection pipe 4.4, and therefore the functions of fixing the three-cavity urinary catheter and preventing the three-cavity urinary catheter from slipping are achieved.

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 mm square to 0.5 mm square. Alternatively, the flow area of the exhaust port is set such that: the time for completing the air discharge in the maximum inflation state to equalize the internal and external air pressures is a set time period, for example, in the range of 0.3 seconds to 1.0 second, more specifically, for example, 0.5 seconds. The maximum inflation state refers to a state that the air pump works to enable the tube band to be inflated with the most air in an anti-blocking operation period.

In an alternative embodiment, on the drain tube 9, a rubber elastic balloon is provided. Advantageously, said rubber-elastic balloon is arranged in series on the drain tube 9.
