GB 9706.217-2020 Medical electrical equipment—Part 2-17:Particular requirements for the basic safety and essential performance of automatically-controlled brachytherapy afterloading equipment
Basic Information
Scope
This section applies to the basic safety and basic performance of automatic controlled brachytherapy afterloading medical electrical equipment, hereinafter referred to as ME equipment.
If a chapter or article explicitly states that it only applies to ME equipment or only to ME systems, the title and its content also apply. Otherwise, the chapter or article applies to both ME equipment and ME systems.
Except for 7.2.13 and 8.4.1 in the general standard, there are no special requirements for the physiological function hazards of ME equipment or ME systems within the scope of this section.
Note: See 4.2 of the general standard.
This section applies to automatic controlled brachytherapy afterloading equipment, which is used for the treatment and relief of diseases.
This section stipulates requirements for:
a) Automatic controlled afterloading ME equipment
1) Contains and only uses sealed radioactive sources emitting beta, gamma, or neutrons, or is designed and manufactured for automatic controlled afterloading ME equipment for brachytherapy.
2) Can automatically send the sealed radioactive sources from the storage source or the brachytherapy X-ray sources from a reference position outside the patient's body to the treatment position within the applicator and return to the storage source or the reference position of the brachytherapy X-ray sources.
3) Designed to have contact with the patient.
4) The source drive mechanism should automatically complete the movement of the radioactive sources according to the preset program controlled by a control timer or timing device. The control timer or timing device can be a programmable electronic subsystem (PESS, computer or microprocessor) or a non-programmable electronic system.
b) ME equipment
1) Under normal use, it is operated by an operator who has been properly authorized or qualified for the specific medical applications and specific clinical uses, suc
