Embodiment Construction

[0018] The test system for the water vapor permeability of the dressing of the present invention, such as figure 1 As shown, the test box body (1) is included, the front part of the test box body (1) is provided with a box door, and the upper part of the test box body is provided with a fan (2). A lower partition (6) and an upper partition (9) are fixed in the test box (1). A heater (7), a temperature and humidity sensor (4) and an electronic scale (5) are arranged on the lower partition board (6). The electronic scale (5) is provided with a dressing container, and the dressing container can be a common dish or bowl container. The lower part of the lower partition (6) is provided with a control circuit board, which is electrically connected with the fan (2), the heater (7), the temperature and humidity sensor (4) and the electronic scale (5). The control circuit board can receive the data information of the temperature and humidity sensor (4) and the electronic scale (5) and c...

Abstract

A test method for the ability of a dressing to transmit water vapor. The dressing container is a wound model for the ability of the dressing to transmit water vapor. The wound model for the ability of the dressing to transmit water vapor has a transparent shell. Groove, sponge groove and through hole, groove, sponge groove and through hole are communicated, through hole communicates with the liquid storage chamber of transparent shell, cover side wall is opened into pinhole, enters pinhole and sponge groove communicates. The design of the wound model through the ability of the dressing to transmit water vapor can test the quality of the dressing to absorb liquid at the same time, so that the correct selection of the liquid control of different dressings can be made in medicine.

Description

Technical field [0001] The invention relates to the field of quality inspection of medical device products, and specifically is a test method for the ability of dressings to permeate water vapor. Background technique [0002] The inspection of the ability of dressings to permeate water vapor is an important part of the quality inspection of medical devices. However, there are currently the following problems: the ambient temperature and relative humidity of the patients using the dressing are different, and the wound sites of the patients are different. The composition and amount of wound exudate are also different. Even for the same wound of the same patient, the composition and amount of wound exudate at different periods are different. Therefore, if you want to compare and evaluate the liquid controllability of different dressings, a unified test platform must be established, including the same test model, a uniform temperature and humidity environment, the same body position...
