308nm Excimer Phototherapy Device (CN-308E, KN-4003B3, KN-4003B4, KN-5000C, KN-5000D, KN-5000H, KN-5000K)

This device is designed to treat vitiligo and psoriasis by emitting narrowband ultraviolet B (UVB) radiation at 308 nanometers. The targeted phototherapy promotes repigmentation in vitiligo and reduces inflammation in psoriasis, though it must always be used under medical supervision in clinical settings.

The 308nm Excimer Phototherapy Device is supplied as a reusable medical instrument, meaning it is intended for repeated use within a medical facility. Proper storage and handling must follow standard medical device protocols to ensure sterility and functionality between treatments, as outlined in the manufacturer’s guidelines.

This device has received FDA 510(k) clearance and complies with the Medical Device Directive (MDD), classifying it as a Class II device. These pathways confirm its safety and effectiveness for dermatological use under physician supervision, ensuring it meets regulatory standards for targeted phototherapy in medical institutions.

Yes, this device comes in multiple models (CN-308E, KN-4003B3, KN-4003B4, KN-5000C/D/H/K), each potentially tailored for specific dermatological applications. While exact differences aren’t detailed here, the variations likely cater to different treatment parameters or patient needs, such as varying emission intensities or treatment areas, under the same core principle of 308nm UVB therapy.

Since it is a reusable medical instrument, storage must adhere to standard protocols for UV-based devices to prevent degradation of the light source or contamination. The manufacturer’s instructions (not provided here) should specify environmental conditions—such as temperature, humidity, and protection from direct light—while ensuring it remains in a clean, sealed state when not in use.
