From April 1, 2024, some beauty units shall not be produced, imported, or bought with out acquiring a medical system registration certificates, which embrace radiofrequency (RF) gear. For the record of units, please click on HERE
NMPA launched the ultimate model of “Registration Guideline for Radiofrequency Aesthetic Units” on April 12, 2023.
The radiofrequency (RF) aesthetic gear, a Class III system, refers to merchandise that use electrical vitality corresponding to radio frequency present (normally 200kHz or extra) or electrical subject (normally 13.56 or 40.68MHz) to behave on human tissues to provide thermal results to deal with pores and skin sagging, scale back pores and skin wrinkles, shrink pores, agency/elevate pores and skin tissue, or deal with zits, scarring, or scale back fats (fats softening or breakdown). They embrace standing, desktop, and handheld units.
Huge gamers within the RF aesthetic market embrace Alma Lasers, Cymedics Cynosure, Beco Medical, EndyMed, Inmode, Lumenis, Lutronic, Ibramed INDIBA, SharpLight Applied sciences, Venus Idea, Candela, and Solta Medical, a few of which already entered China.
Overview Focus Areas
The 29-page RF gear guideline elaborates the overview focus areas. The important thing components are described as following:
- Registration unit division
It shall meet the necessities of the “Tips for the Division of Medical Gadget Registration Items”, and based mostly on the technical precept, structural composition, efficiency indicators and scope of software of the product.
Vertical/desktop RF beauty units and handheld RF beauty units ought to be divided into separate registration items:
For vertical/desktop RF aesthetic gear, the primary unit and equipment are normally declared as the identical registration unit. For single-use radio frequency equipment, it can be declared individually, however the info of the host have to be clearly used. The impartial electrode may be declared as a product part or used at the side of a basic impartial electrode.
Conductive pastes, impartial coolants, cooling tanks and different merchandise used at the side of radio frequency aesthetic gear usually are not the identical registration unit as radio frequency aesthetic gear. Non-medical purposeful equipment corresponding to pores and skin stickers and markers used within the therapy course of are normally not considered product parts.
- Efficiency index necessities
The working frequency, rated load, rated energy of every mode, and the output vitality and vitality density with all out there remedy electrodes ought to be clearly outlined. Clear all of the adjustable parameters, and the mode with pulse output mode ought to specify the heartbeat frequency and pulse interval.
The world and dimension necessities of the remedy electrodes ought to be specified. Dot matrix and microneedle electrodes ought to have clear electrode dimension and distribution spacing. The microneedle electrode ought to specify the size of the microneedle, and whether it is adjustable, the adjustment vary and adjustment methodology also needs to be specified.
If it comprises a impartial electrode, it ought to meet the related microbial restrict necessities.
If a foot change is included, the foot change shall meet the necessities of YY 1057.
If there’s a temperature measurement perform, the temperature measurement vary and measurement accuracy ought to be specified. If it has a temperature management perform, the temperature management vary and management accuracy ought to be specified.
If it has a cooling perform, the place of the cooling floor ought to be described within the product diagram, and the adjustment vary and management accuracy of the cooling temperature ought to be specified.
If it has unfavorable strain perform, the vary and accuracy of unfavorable strain parameters ought to be clarified.
- Electrical Security Necessities
Basic security ought to meet the necessities of GB 9706.1 normal. For gear supposed for use in a house atmosphere or different non-professional medical atmosphere, it ought to meet the necessities of the YY 9706.111 normal.
For therapeutic merchandise that use present impact to behave on the human physique, the particular security shall meet the necessities of the GB 9706.202 (GB 9706.4) normal. The therapy gear that makes use of the electrical subject impact to behave on the human physique ought to take into account the corresponding particular security necessities in keeping with its design traits. For instance, the frequency of 40.68MHz belongs to the ultra-short wave frequency vary and may meet the necessities of the GB 9706.203 normal.
RF aesthetic gear software program is normally embodied as software program parts, and related software program analysis studies ought to be supplied in accordance with the related necessities for software program parts within the Tips for Registration and Overview of Medical Gadget Software program (Revised in 2022).
If the export of system knowledge and therapy parameters is concerned, cybersecurity-related analysis supplies ought to be supplied in accordance with the necessities of the Tips for the Overview of Medical Gadget Cybersecurity Registration (Revised in 2022).
The biocompatibility of the elements in direct or oblique human contact with the completed product ought to be evaluated. The parts anticipated to contact with the affected person within the RF beauty system are primarily the remedy electrode and the impartial electrode.
The therapeutic electrode and impartial electrode utilized in non-invasive therapy are anticipated to be in short-term contact with the affected person’s pores and skin. In keeping with the necessities of GB/T 16886.1, the biocompatibility analysis ought to at the very least take into account the next necessities: cytotoxicity, sensitization, and pores and skin irritation. Equipment for invasive remedies (together with lattice and microneedle electrodes) are anticipated to contact with broken pores and skin or subcutaneous tissue, and biocompatibility analysis ought to at the very least take into account the next necessities: cytotoxicity, sensitization, and intradermal reactions. As well as, some microneedle electrodes should be used with a particular protecting casing. The casing is predicted to keep up a correspondence with the affected person’s pores and skin. Nevertheless, as a result of the microneedle electrode will pierce the pores and skin throughout use, the casing could get contact with broken pores and skin or tissue. Subsequently, the stimulation take a look at Contemplate intradermal responses as regards to microneedle electrodes.
For hand-held units, the system deal with and therapy electrodes are anticipated to be in short-term contact with the affected person’s pores and skin, and biocompatibility analysis ought to take into account the cytotoxicity, sensitization, and pores and skin irritation. When finishing up biocompatibility analysis, the system may be thought of as a complete, or it may be thought of individually in keeping with the handles and therapy electrodes that contact completely different elements of the human physique.
