Static electricity is generated by contact, departure, friction, induction, etc. between objects. Static electricity is very harmful to medical electronic equipment, it is directly related to whether it can guarantee the safe operation in the medical process. Medical equipment is a high-tech product that integrates light, machinery and electricity. It is directly used for testing various parameters and states of the human body. Therefore, the electrostatic protection of medical equipment is particularly important.
The human body generally carries a static electricity of 100V-200V. In wet and rainy days, the static electricity is about 100V. In dry weather, the static electricity of the human body increases with the movement of the human body and friction with clothing, up to 1000V. Frequent contact with the human body cannot be avoided. Therefore, medical engineering technicians must educate equipment operators on the basic knowledge of electrostatic protection, so that they fully realize the dangers of static electricity, and prevent high static electricity caused by poor grounding of the instrument and friction. In addition, some valuable medical equipment often uses some anti-static products for protection treatment, so that the harm of static electricity is minimized.
