Description

Technical Field

[0001] The invention belongs to the technical field of skin modeling devices, and in particular relates to a skin injury modeling device. Background Art

[0002] In vitro research on cosmetics is increasingly focusing on the impact of complex environments on the skin, so a device that can comprehensively simulate temperature, humidity, and airflow is needed. Currently, common environmental simulations include light source simulators (such as ultraviolet light, sunlight, yellow light, etc.), and existing laboratory environmental simulation devices (temperature control devices, humidity control devices, wind control devices) have single functions and cannot simulate complex environmental conditions at the same time.

[0003] At present, the skin injury modeling tools are mostly focused on simulating light damage and physical external wounds. For example, CN201320270057.4 discloses a UV irradiator that uses a Philips PL-S9W / 01 UV lamp. Its advantages are low research cost, easy use, adjustable radiation dose, and stability of batch biological detection models. CN215688691U discloses a tool that is convenient for skin injury modeling. When modeling skin injuries on animals, the extension length of the blade can be adjusted according to the use requirements to ensure the accuracy of the cutting depth and the success rate of the experiment.

[0004] The current skin damage models mainly rely on UV or chemical stimulation, such as SLS stimulation, to create damaged skin models. Although the existing devices for preparing damaged models can control temperature and humidity separately, they cannot simulate the comprehensive environment of the skin model, including controlling the temperature, humidity or local airflow of the skin model.
