Description

Technical Field

[0001] The utility model belongs to the technical field of drainage devices, and particularly relates to a closed and monitorable drainage kit for continuous bladder irrigation. Background Art

[0002] Continuous bladder irrigation is a method of dripping sterile irrigation fluid into the bladder through a three - lumen transparent hose and draining the fluid dropped into the bladder to the outside of the body by the siphon principle. Its functions are to clean the bladder, remove foreign substances such as blood clots, mucus, and bacteria in the bladder, prevent infection, reduce complications, and promote the recovery of patients. In the past, the irrigation fluid was hung on an infusion stand. After connecting the irrigation tube to the irrigation fluid and then connecting it to the side path of the three - lumen transparent hose, the main outlet of the urinary catheter was directly connected to the urine bag. Using the siphon principle, the irrigation fluid was drained out, and the bottom outlet of the urine bag was continuously opened, and a transparent glass bottle or a bucket was used to collect the drained fluid. If urine volume needs to be recorded, the drained fluid has to be poured into a measuring cup for measurement, which is laborious and time - consuming; when the urinary catheter is blocked and the drainage is interrupted, it cannot be detected early in a timely manner. Often, it is not noticed until the patient feels abdominal distension and pain in the bladder area; the drained fluid contains blood, urine, germs, necrotic tissue, etc. At night, due to the negligence of the accompanying personnel, the drained fluid overflows the container and flows to the ground, which easily pollutes the environment and has the potential risk of nosocomial infection; for bladder cancer patients, after immediate postoperative intravesical perfusion chemotherapy and clamping of the urinary catheter, when the catheter is opened in the ward for continuous bladder irrigation, the drained fluid contains chemotherapy drugs, and the exposed fluid is likely to pollute the environment and cause harm to the people in the ward environment.

[0003] In order to solve the deficiencies of the existing technology, people have carried out long - term exploration and proposed various solutions. For example, a Chinese patent document discloses a bladder irrigation pipeline [201721204208.0], which includes a Y - type three - way pipe. The Y - type three - way joint includes a main pipe joint and two branch pipe joints. The angles between the main pipe joint and the two branch pipe joints are equal, and the angle between the two branch pipe joints is designed as an acute angle. The main pipe joint is connected to a bladder irrigation fluid plug through a flushing pipe. One of the two branch pipe joints is connected to a transparent hose plug through a transparent hose connecting pipe, and the other is connected to a urine collection bag joint through a urine collection bag connecting pipe; the inner diameters of the flushing pipe, the transparent hose connecting pipe, and the urine collection bag connecting pipe are set to 4 - 6 mm, and each of them is provided with a clip or a flow regulator. The inner arm of the clip is provided with two lugs, one end is provided with a fixed tooth, and the inner wall of the other end is provided with an adjusting ratchet tooth.
