The description focuses on the material properties and physical function of the wound dressing, with no mention of AI or ML.
Yes
The device is indicated for managing various wounds (pressure sores, diabetic ulcers, burns, skin donor sites) to promote healing, which is a therapeutic function.
No
The device is described as a topical dressing for wound management, not for identifying or diagnosing a medical condition.
No
The device description clearly states it is a "bacterial synthesized cellulose mesh," which is a physical material, not software. The performance studies also focus on physical properties and biological interactions, not software performance.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is a "topical dressing to manage pressure sores, diabetic ulcers, 1st to 2nd degree burns and skin donor sites." This describes a device that is applied directly to the body for therapeutic purposes (wound management).
- Device Description: The description details the physical properties and function of the dressing, focusing on its role in providing a suitable environment for wound healing.
- Lack of Diagnostic Activity: There is no mention of the device being used to analyze samples from the body (like blood, urine, tissue, etc.) to diagnose a condition, monitor a disease, or screen for a health issue. IVDs are designed for these types of in vitro analyses.
Therefore, the Bios King Biocellulose Film is a medical device, specifically a wound dressing, but it does not fit the definition of an In Vitro Diagnostic device.

Dear Dr. Kuo:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

Device Description:
Bios King Biocellulose Film is made of bacterial synthesized cellulose mesh with a selectively permeable structure allowing water evaporation, and thus provides a moist but not damp environment for wound healing. Bios King Biocellulose Film is resistible to the tensile force generated from the wound handing. It can adhere to wound beds without fixation devices.
Indications for Use:
Bios King Biocellulose Film is indicated as a topical dressing to manage pressure sores, diabetic ulcers, 1st to 2nd degree burns and skin donor sites.
Technological Characteristics:
Bios King Biocellulose Film is made of biocellulose mesh synthesized by a gram-negative bacteria strain called acetobacter xylinum, which secrets a large quantity of organized and twisted cellulose microfibrils. The pores within the Bios King Biocellulose Film permit water vapor transportation. Bios King Biocellulose Film is removed of water content through lyophilization process. After that, it barely absorbs water. Bios King Biocellulose Film passes endotoxin test, skin irritation test and maximized skin sensitivity test following ISO 10993 protocols. Bios King Biocellulose Film biocellulose film encompasses tensile strength and readily conforms to irregular wound shapes.
Substantial equivalence:
The safety and efficacy of Bios King Biocellulose Film are substantially equivalent to the predicate devices, including BioFill Biocellulose Dressing Sterile (K950621) and X-CELL Wound
