Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, and in particular to a disposable enema device. Background Technology

[0002] A traditional enema device is a medical instrument specifically designed for bowel cleansing and enema therapy. It works by instilling specific liquid medications or cleansing agents into the intestines to achieve purposes such as cleansing the intestines, softening stool, and treating diseases. The enema device mainly consists of a reservoir bag, tubing, rectal tube, and control valve. During operation, medical personnel first deliver the lavage solution from the reservoir bag to the rectal tube through the tubing, and then regulate the flow rate and volume of the liquid using the control valve to achieve bowel cleansing. Existing enema devices are typically made of metal or plastic and require cleaning and sterilization after use for reuse. However, these devices present hygiene problems such as incomplete cleaning leading to bacterial growth and increasing the risk of cross-infection. Existing disposable enema devices incorporate a heating pump inside the reservoir bag to control the temperature of the enema solution; however, this design does not achieve uniform heating of the enema solution and also presents certain hygiene issues.

[0003] Therefore, it is crucial to provide a technical solution that can solve the above-mentioned technical problems. Utility Model Content

[0042] The heat exchanger is designed to convert the low-temperature liquid in the liquid heating layer 5 into a liquid at the desired temperature (which can be adjusted according to actual conditions).

[0043] Furthermore, the weight sensor 12 is bonded to the bottom of the storage bag 1 and is located at the bottom of the inner enema fluid receiving cavity; preferably, there are two or more weight sensors 12, which are symmetrically arranged along the center of the bottom of the storage bag 1, for accurately monitoring the amount of enema fluid in the storage bag 1.

[0045] Furthermore, a scale 16 is provided on the outer surface of the anal tube 15, which is used to reflect the length of the anal tube 15 entering the patient's body.

[0046] It should be noted that the heat exchange component 17 and the weight sensor 12 are reusable, while other components can be sterilized; the heat exchanger, inlet pump, and outlet pump can be manually adjusted.

[0047] When using it, the following steps are included:

[0048] (S1) Medical staff check whether the disposable enema device is intact, then add the liquid heating medium to the middle layer of the storage bag 1 as the liquid heating layer, and connect the inlet pipe 8 and the outlet pipe 9 to the heat exchange component 17.
