Chapters and articles marked with an asterisk (*) provide explanatory notes in Appendix AA "Guidelines and Basic Principles for Specific Provisions" of this part. Medical Electrical Equipment Part 2-50. Basic safety and safety of infant light therapy equipment Special requirements for basic performance 201.1 Scope, purpose and related standards In addition to the following, Chapter 1 of the general standard applies. 201.1.1 *Scope replace. This section specifies the safety requirements for infant phototherapy equipment. However, if the manufacturer has indicated in its risk management Compared with the benefits of preparation treatment, the related hazards and risks can be maintained within an acceptable range, and the replacement that meets specific provisions and has the same safety Substitution method will not be regarded as a violation of relevant regulations. This section applies to the basic safety and basic performance of infant light therapy equipment, also known as ME equipment. If a clause or sub-clause is specifically applicable to ME equipment or ME system, the title and content of the clause or sub-clause will be clearly stated. Make it clear. If not clearly stated, this clause or sub-clause applies to the relevant ME equipment and ME system. Except for 7.2.13 and 8.4.1 in the general standards, the special requirements of this part do not include ME equipment or ME systems within the scope of this part The inherent hazards of expected physiological functions. Note. See 4.2 in the general standard. This section does not apply to. --- Devices that provide heat through blankets, pads or mattresses in medical use, see YY 9706.235 for information; ---Infant incubator, see YY 0455 for information; ---Infant transfer incubator, see YY 9706.220 for information; ---Infant radiant warmer, see GB 11243 for information. 201.1.2 Purpose replace.
