(14) Central nervous system 

Brain and medulla spinalis.

(15) Stand alone software

A software with one or more medical purposes which may complete the intended purposes without using a medical device hardware and runs on the universal computing platform.

(16) Medical device with measuring functions

A medical device intended to measure the physiological, pathological and anatomic parameters or make quantitative determination on the energies/substances entering or leaving the human body. The measuring results shall be accurately quantified, and the accuracy of such results may have obvious effects on patient's health and safety.

(17) Chronic wound

A wound which is not healed for a long time due to various reasons, such as venous ulcer, arterial ulcer, diabetic ulcer, traumatic ulcer and pressure ulcer, etc..

Article 4 According to degree of risk (from low to high), the classifications of medical devices are divided into class I, class II and class III in due order.

The risk degree of a medical device shall be determined comprehensively according to the intended purpose, structural characteristics, pattern of use, status of use as well as whether the device is body contacting.

Article 5 According to the factors which may influence the degree of risk of medical devices, medical devices are divided as follows:

(1) Non-active medical devices and active medical devices, according to structural characteristics.

(2) Body-contacting device and non-body-contacting device, according to whether they are in contact with human body.

(3) Patterns of use of medical devices, according to their different structural characteristics and whether are in contact with human body, include: 

Non-active body-contacting devices: liquid transportation devices, blood and other body fluids alternation devices, medical dressing, invasive devices, reusable surgical devices, implantable devices, contraceptive and family planning devices and other non-active body-contacting devices.
