Hospital medical devices can be divided into three categories, namely, diagnostic, therapeutic two categories and the necessary level of different requirements of medical equipment classification.

First, the diagnostic equipment class can be divided into the following categories:

(X-ray machine, CT scan, magnetic resonance, B super, etc.), analytical instruments (various types of counters), the use of various types of instrumentation (thermometer, blood pressure meter, microscope, audiometer, various physiological recorder, etc.) , Biochemical, immunoassay instruments, etc.), electrophysiological (such as ECG machine, EEG machine, EMG machine, etc.).

Second, the treatment of equipment can be divided into the following categories:

(Such as a variety of anesthesia machine, ventilator, cardiopulmonary bypass, etc.); radiotherapy machinery (such as deep X-ray therapy machine, cobalt 60), radiotherapy and chemotherapy (such as deep radiotherapy machine, laser treatment machine, Treatment machine, accelerator, gamma knife, all kinds of isotope therapy, etc.); other categories (microwave, hyperbaric oxygen, etc.).

Third, the hospital essential medical equipment grade requirements can be divided into three categories:

The first, the second, and the third. That is, the first category refers to the routine management of sufficient to ensure its safety, effectiveness of the medical device; the second category refers to its safety, effectiveness should be controlled by the medical device; the third category refers to the implantation of the human body, Used to support and maintain life; the human body is potentially dangerous and its safety, effectiveness must be strictly controlled medical equipment.

It is worth noting that if a medical device contains a class and two categories, then this medical device is the second category. If a medical device contains two and three categories, then this medical device belongs to three categories. And so on, we can draw the same conclusion.

Home with a variety of simple medical equipment, such as thermometer, stethoscope, sphygmomanometer, etc., with the development of electronic technology, automatic, semi-automatic electronic home medical equipment such as electronic sphygmomanometer, blood glucose tester, electronic thermometer and so on.
