Patent ID: 8438940

Claim:
An apparatus for simulatively measuring an environment in a microspace between a wound on human skin and a wound dressing, the apparatus comprising: a constant temperature-and-humidity chamber which simulatively reproduces an environment in which a wound dressing is practically used, a warming unit which is disposed in the constant temperature-and-humidity chamber and warms a container holding therein a water retentive member, which holds water, up to a simulated human body temperature, a water vapor diffusion-controlling member, which covers an opening of the container and controls the permeation of water vapor, a sample holder with water vapor permeability, the sample holder being provided on the water vapor diffusion-controlling member to hold a sample thereon such that a closed space simulating the microspace is formed between the sample holder and the sample, and a sensor which measures temperature and/or humidity in the closed space between the sample holder and the sample.
