Static electricity is a relatively static charge, which is a common natural phenomenon. In daily life, static electricity is generated by friction, pressure, heat, impact, and the like. The static electricity has high voltage, low energy and great harm.
The phenomenon of electrostatic discharge is often encountered in daily life, and its harmfulness has attracted more and more attention. Medical engineers and technicians should be aware of the dangers caused by static electricity in hospitals and actively guard against them.
The main hazard of static electricity in hospitals is: because the electric field strength near the charged body reaches a certain number and discharge occurs, so static electricity can cause damage to medical equipment, and its electric spark may ignite some inflammable and explosive materials, causing explosions and Fire. Static electricity can also cause electric shock to people. When the human body approaches an electrostatic body or a static-charged human body approaches the grounding body, it may be shocked. Because the static energy is very small, the electric shock itself will not cause serious harm to people, but its associated damage may cause secondary injury such as falling and falling due to electrostatic shock, and also cause nervousness or fear of the operator and the patient. Affect the test results and treatment effects, and may even cause psychological damage.
The harm caused by static electricity to hospitals should be highly valued on the one hand, and more importantly, measures should be taken to prevent and eliminate them. To ensure good grounding of the medical equipment, the equipment must be well connected to the casing and the instrument vehicle to maintain the same potential and prevent the accumulation of electric charge in the equipment. The operator of the equipment must wear a grounded wrist strap and wear qualified high quality defense. Electrostatic clothing to prevent the danger of static electricity and adverse effects on the human body.
