Description

Technical Field

[0001] This application relates to the field of peritoneal dialysis nursing technology, specifically a peritoneal dialysis nursing waste fluid collection and treatment device. Background Technology

[0002] Peritoneal dialysis is one of the commonly used renal replacement therapies for patients with end-stage renal disease. Patients need to have dialysis fluid infused into the peritoneal cavity multiple times a day, remain there for a period of time, and then have the dialysis waste fluid, containing metabolic waste products, drained out. This process generates a large amount of medical waste fluid, which may contain bacteria, toxins, and chemicals, and is classified as infectious medical waste.

[0003] Currently, in home or hospital care, peritoneal dialysis waste fluid is usually disposed of by directly draining it into a regular container or toilet. This method has significant drawbacks: odor diffusion: the waste fluid has a strong urine odor, and direct exposure to the air will pollute the indoor environment, causing discomfort to patients and their families; infection risk: aerosols or droplets in the waste fluid may carry pathogens and spread into the air, posing a risk of cross-infection; inconvenient measurement: ordinary containers do not have measuring functions, making it difficult for medical staff or patients to accurately observe and record the drainage volume each time, which is not conducive to monitoring the patient's condition; and cumbersome disposal: especially for patients with limited mobility, moving large amounts of waste fluid from the container to the toilet for disposal is both laborious and inconvenient, and spillage is likely to occur.

[0004] Therefore, this application provides a peritoneal dialysis nursing waste fluid collection and treatment device to solve the above problems. Utility Model Content

The insert slot allows the filter assembly to be fixed inside the mounting plate and the sealing cap to be fixed to the top of the collection box. The collection tube and the outlet end of the peritoneal dialysis machine's drainage tube are introduced into the collection tube. The control valve inside the collection tube is opened, and the waste liquid flows into the collection box under gravity for collection. At this time, the air in the collection box is compressed by the waste liquid and discharged outward through the exhaust pipe. When the discharged air passes through the filter assembly, the odor molecules in it are adsorbed by the activated carbon, and any bacteria it may contain are blocked or killed by the antibacterial filter cotton, thus achieving safe exhaust without odor or bacteria. The waste liquid collection volume can be observed by the scale inside the observation tank.

At this time, the air inside the collection box is compressed by the waste liquid and discharged through the exhaust pipe. The discharged air passes through the filter assembly. During operation, odor molecules are adsorbed by activated carbon, and any bacteria that may be present are blocked or killed by antibacterial filter cotton, thus achieving safe exhaust without odor or bacteria. The amount of waste liquid collected can be observed by the scale inside the observation tank. When cleaning is required, the entire device can be moved to a bathroom or a large medical waste liquid collection point, the bottom discharge pipe can be aligned with the sewer, and the control valve can be opened. The waste liquid can then be discharged smoothly under gravity.
