Q & AAbout "touch parts" or "applied parts" (Applied Parts, AP) is usually applied.
About "touch parts" or "applied parts" (AP) are usually applied to medical equipment that has "direct contact" with the patient.
It can be divided into three main types:
• Type CF (Cardiac Floating): It is the most rigorous classification, connected to the patient's heart (cardiovascular), such as: dialysis machine, heart rhythm regulator.
• Type BF (Body Floating): Compared with the less rigorous classification of CF, there is electrical contact or medium-to-long-term contact with the patient, but it is not directly connected to the heart. For example: blood pressure monitoring equipment, ultrasonic equipment and incubators, etc.
• Type B (Body): The least rigorous classification, can be grounded but has no electrical contact with the patient, and can be immediately removed from the patient's contact site. For example: MRI equipment, medical laser equipment, hospital beds, light therapy equipment, etc.
The Type CF and Type BF equipment can also be referred to as F-type applied part, because it will contact the patient, so it is necessary to regulate the grounding method and the amount of current passing through the human body.
As for the grounding method, Type B equipment does not touch the human body during use, so it can be directly grounded. But for F-type (Type BF, Type CF), it must be floating with the ground. Isolated and cannot be directly grounded.
