Recently look at "GB 9706.1-2007 medical electrical equipment: safety requirements", some words do not understand the meaning. Such as "patient"
Such as "patient leakage current", "patient circuit", these words in the end what the meaning of the patient? Please know that friends have educated us.
Standard Number: GB 9706.1-2007
Standard specification: Medical electrical equipment - Part 1: General requirements for safety
This standard applies to the safety of medical electrical equipment.
While this standard is primarily concerned with security issues, it also includes requirements for reliable operational compliance.
The safety aspects of the equipment due to the expected physiological effects of this standard are not taken into account.
Unless otherwise specified in the standard text, the appendix in the standard does not require enforcement.
"Patient leakage current": patient application part (in the diagnosis or treatment process, the patient may be exposed to the part, such as: ultrasonic probe, DR plate shell) after the rated voltage increased by 10% after the patient flow to the ground current The
Patient circuit: the application part (in the diagnosis or treatment process, the patient may be exposed to the part).
Patient circuit Please read GB 9706.1-2007 Medical electrical equipment: Safety General requirements in the 5.1.15 content, understand the patient circuit definition, the patient current. The patient leakage current can understand, that is, the circuit on the patient's current, leakage current.
