[0029] Further, as Figure 3 Shown, urinary catheter 25 is made of natural rubber, silicone rubber or polyvinyl chloride PVC pipeline, can be inserted into urinary bladder via urethra to drain urine, after urinary catheter 25 is inserted into urinary bladder, there is an air bag 27 fixed urinary catheter 25 near the head end of urinary catheter 25 to stay in urinary bladder, and it is not easy to come out.

[0030] Further, as Figure 3As shown, the second interface 23 of the rotary valve 21 is connected with the urine bag 34, and the first interface 22 of the rotary valve 21 is connected with the detachable rotary joint 18. When the bladder irrigation or the bladder pressure measurement is not needed, the connection between the additional device 1 and the guide assembly 2 is disconnected, that is, the arrow direction of the rotary valve 21 is directed to the direction of the first interface 22, and the arrow direction of the rotary valve 21 is the closed end. The arrow direction of the rotary valve 21 is rotated to the closed side, so that only the urine collecting assembly 3 is connected with the bladder, and the urine collecting assembly 3 can collect the urine. When the bladder irrigation or the bladder pressure measurement is needed, the arrow direction of the rotary valve 21 is directed to the second interface 23, so that only the additional device 1 is connected with the bladder. The irrigation liquid is injected by the additional device 1 and then flows into the bladder through the guide assembly 2, so that the bladder is irrigated. Through the use of the guide assembly 2, the additional device 1 and the urine collecting assembly 3 can be quickly switched, and the bladder catheter is more convenient to use. Compared with the current clinical bladder pressure measurement, the urine tube is separated, and the risk of urethral infection is reduced.

[0031] The additional device 1 comprises a needle 11, one end of the needle 11 is fixedly connected with one end of a first extension pipe 13, the other end of the first extension pipe 13 is fixedly connected with one end of a drip bottle 15, the other end of the drip bottle 15 is fixedly connected with one end of a second extension pipe 16, the other end of the second extension pipe 16 is provided with a detachable rotary joint 18, and the outside of the second extension pipe 16 is provided with a standard ruler scale 17.

Several groups of positioning through-holes 44 are arranged at equal intervals to facilitate the closed loop size of the bandage 42, thereby preventing edema of the patient's limb and leg compression.

[0037] Working Principle: The urinary catheter 25 is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) and can be inserted into the bladder through the urethra to drain urine. After the urinary catheter 25 is inserted into the bladder, a balloon 27 near the tip of the urinary catheter 25 secures the urinary catheter 25 in the bladder and prevents it from coming out.

[0038] The second interface 23 of the rotary valve 21 is connected with the urine bag 34, and the first interface 22 of the rotary valve 21 is connected with the detachable rotary joint 18, when the bladder flushing or the bladder pressure measurement is not needed, the connection between the additional device 1 and the guide assembly 2 is disconnected, that is, the arrow direction of the rotary valve 21 is directed to the direction of the first interface 22, the arrow direction of the rotary valve 21 is the closed end, and the rotary valve 21 is rotated to the closed side, so that only the urine collecting assembly 3 is connected with the bladder, and the urine collecting assembly 3 can collect the urine, when the bladder flushing or the bladder pressure measurement is needed, the arrow direction of the rotary valve 21 is directed to the second interface 23, so that only the additional device 1 is connected with the bladder, and the flushing liquid is injected by the additional device 1 and then flows into the bladder through the guide assembly 2, so that the bladder is flushed. Through the use of the guide assembly 2, the additional device 1 and the urine collecting assembly 3 can be quickly switched, and the bladder catheter is more convenient to use.

[0039] The total capacity of the graduated dropper bottle 15 is 100ml, and the scales are 25ml, 50ml and 75ml, and the setting reason is that 25ml is recommended by experts for bladder pressure measurement, and the total capacity of 100ml is convenient for observation and measurement. If only the bladder flushing is needed, all the pipe clamps 12 can be opened. If the bladder pressure measurement is needed, the pipe clamp 12 outside the first extension pipe 13 is opened, the pipe clamp 12 outside the second extension pipe 16 is closed, then the pipe clamp 12 outside the first extension pipe 13 is closed after the dropper bottle 15 is filled with 25ml liquid, the exhaust valve 14 outside the dropper bottle 15 and the pipe clamp 12 outside the second extension pipe 16 are opened, 25ml liquid is completely flowed into the bladder under the action of gravity, and the standard scale scale 17 segment is used for measuring the bladder pressure. When 25ml of normal saline enters the bladder, the pipe clamp 12 outside the second extension pipe 16 is closed, the exhaust valve 14 outside the second extension pipe 16 is opened, the "0" point of the standard scale scale 17 segment of the second extension pipe 16 can be directly placed at the horizontal iliac spine of the midaxillary line, and the bladder pressure can be measured according to the water column fluctuation, which is very fast and convenient.
