AI Technical Summary

Technical Problem

Existing perineal irrigation devices cannot achieve precise temperature control, single use, adjustable water pressure, prevention of sewage overflow, ease of operation and portability in outdoor, clinical and home settings, and have problems such as cross-infection risk and poor portability.

Method used

A disposable temperature-controlled perineal douche device was designed, which adopts a modular functional configuration, including a liquid storage and temperature control unit, a pressurized douche unit and an optional wastewater recovery unit. It adopts a pre-assembled integrated structure, uses microcapsule phase change material to achieve temperature control, manually squeezes the air bladder for pressurization, and uses a flexible catheter and collection tank to collect wastewater. The whole device is made of medical-grade sterile material and sealed packaging.

Benefits of technology

It achieves an integrated design that combines precise temperature control, single use, adjustable water pressure, prevention of sewage overflow, and ease of operation and portability, adapting to perineal cleaning needs in multiple scenarios, reducing the risk of infection, and improving the safety and convenience of use.

Abstract

The application discloses a disposable temperature control type perineum flushing device, and belongs to the technical field of perineum cleaning, aiming to solve the problems of the current disposable flushing tool, such as no temperature control, no sewage collection, uncontrollable water pressure, complicated operation, easy cross infection and poor portability of the current temperature controllable flushing device. The device comprises a pre-assembled integrated liquid storage temperature control unit and a pressurized flushing unit, and can be optionally provided with a sewage recovery unit. The liquid storage temperature control unit comprises a liquid storage bin and a temperature control assembly, the temperature control assembly is composed of a food-grade heat preservation lining and a microcapsule phase change material layer, and the temperature of the flushing liquid in the liquid storage bin can be stably maintained at 41-43 DEG C. The extrusion air bag of the pressurized flushing unit is provided with a one-way air inlet valve, the flushing catheter assembly is provided with a bendable universal catheter, a sterile nozzle and a flow regulating clamp, and the sewage recovery unit is arranged correspondingly to the pressurized flushing unit. The application realizes precise temperature control, sterile one-time use, simple operation and portable integration, is suitable for outdoor, clinical and home nursing, and has high practicality and popularization value.
