[0025] The following is a further detailed description of the present invention in conjunction with the attached Figures 1-3 drawings.

[0026] Embodiment 1: A bladder irrigation device for use after urological surgery, such as Figure 1 、 Figure 3As shown in the figure, it includes a flushing component, a triple-lumen balloon catheter 3, and a drainage component. One end of the triple-lumen balloon catheter 3 is provided with a liquid inlet cavity 31, a balloon inflation cavity 32, and a liquid outlet cavity 33, and an inflatable balloon is provided on the outer side of the other end. The flushing component is connected to the liquid inlet cavity 31, the drainage component is connected to the liquid outlet cavity 33, and the balloon inflation cavity 32 is communicated with the inflatable balloon, and the inflatable balloon is inflated through the balloon inflation cavity 32 to make it expand. The drainage component is provided with a transparent bag 8, and a colorimetric card is installed in the transparent bag 8. The flushing component includes a flushing bag 1, a flushing hose 2, and an intelligent flow rate regulating valve 6 arranged on the flushing hose 2; the flushing hose 2 is a Y-shaped tube, and both ends of the top of the flushing hose 2 are respectively connected to the flushing bag 1, and one end of the bottom is connected to the liquid inlet cavity 31. The flushing hose 2 is made of soft and tough medical silicone material to reduce the irritation to the urethra. Its inner diameter and outer diameter sizes are determined according to the actual flow rate requirements, the inner diameter is 3-5mm, and the outer diameter is 5-7mm; the size of the flushing bag 1 is 500ml-2000ml.

[0027] The intelligent flow rate regulating valve 6 has several regulating gears for controlling the flow rate according to the color number of the colorimetric card. The intelligent flow rate regulating valve 6 automatically adjusts the flow rate of the liquid in the flushing hose 2 according to the selected regulating gear through a preset program.

[0028] The drainage component includes a drainage bag 5, a drainage hose 4, and a drainage regulating valve 7 installed on the drainage hose 4; one end of the drainage hose 4 is connected to the liquid outlet cavity 33, and the other end is connected to the drainage bag 5; the transparent bag 8 is fixedly connected to the drainage bag 5. The drainage bag 5 is used to collect the waste liquid after flushing. The drainage bag 5 has a large capacity, and its size is 3000ml-5000ml; an anti-backflow structure is provided inside the drainage bag 5 to prevent the waste liquid from flowing back into the bladder and causing infection. A drainage port 51 is provided at the bottom of the drainage bag 5, and a drainage valve 52 is provided at the drainage port 51 to facilitate the discharge of the waste liquid in the drainage bag 5.

[0029] The color range of the colorimetric card includes 8 different color numbers, and each color number corresponds to a different color depth of the waste liquid; the colorimetric card is made of waterproof and durable materials, with accurate colors and not easy to fade; the flushing speed ranges corresponding to each color are clearly marked on the colorimetric card, which is convenient for medical staff to quickly read. The flushing speed ranges corresponding to each color clearly marked on the colorimetric card are as follows: when the color of the waste liquid matches the 1-2 color numbers, adjust the flushing speed to 80-100 drops / min; when the color of the waste liquid matches the 3-4 color numbers, adjust the flushing speed to 100-150 drops / min; when the color of the waste liquid matches the 5-6 color numbers, adjust it to 150-200 drops / min; when the color of the waste liquid matches the 7-8 color numbers, adjust the flow rate to the maximum and make it drip in a straight line.

[0030] After transurethral resection of the prostate, select a 1000-ml irrigation bag 1, fill it with an appropriate amount of normal saline as the irrigation fluid, connect the irrigation hose 2, the three-way balloon catheter and the drainage hose 4, and the drainage bag 5. The intelligent flow rate regulating valve 6 is preset with a program for adjusting the flow rate according to the color comparison card, and the color comparison card is placed in a transparent bag 8.

[0031] After starting the irrigation, the waste liquid flows back to the drainage bag 5, and the medical staff observes the color of the waste liquid and compares it with the color comparison card. Suppose the initial color of the waste liquid matches the color No. 3. The intelligent flow rate regulating pump automatically adjusts the irrigation speed to about 120 drops / min.

[0032] As the irrigation progresses, the color of the waste liquid becomes lighter. When it matches the color No. 2, the irrigation speed is adjusted to about 90 drops / min. During the entire irrigation process, if the color of the waste liquid reaches above color No. 5, the medical staff reports to the doctor, and the doctor makes a treatment according to the situation.

[0033] Embodiment 2: A bladder irrigation device for use after urological surgery, as Figure 2 、 Figure 3 shown, is basically the same as Embodiment 1, except that the irrigation assembly includes an irrigation bag 1, an irrigation hose 2, and a high-precision manual regulating valve 9 provided on the irrigation hose 2; the irrigation hose 2 is a Y-shaped tube, and both ends at the top of the irrigation hose 2 are respectively connected to the irrigation bag 1, and one end at the bottom is connected to the liquid inlet cavity 31. The high-precision manual regulating valve 9 has precise scale markings, and the medical staff can manually adjust the irrigation speed.

[0034] For patients after bladder tumor resection, use a 2000-ml irrigation bag 1, connect the irrigation hose 2, the three-way balloon catheter and the drainage hose 4, and the drainage bag 5, and place the color comparison card in the transparent bag 8.

[0035] During the irrigation process, the medical staff observes that the color of the waste liquid in the drainage bag 5 matches the color No. 4, and manually adjusts the high-precision regulating valve to about 130 drops / min according to the markings on the color comparison card.

[0036] If the color of the waste liquid deepens to color No. 6, the medical staff promptly adjusts the flow rate to about 180 drops / min and reports to the doctor. After the doctor's evaluation, it is decided to continue observing, and the medical staff continues to adjust the irrigation speed according to the change in the color of the waste liquid until the irrigation is completed.

[0037] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
