[0039] A control unit 100;

[0040] A plurality of radio frequency sensing units 200, each of which is arranged in a target area on the human body model. The sensing range of each radio frequency sensing unit 200 corresponds to the size of the target area. The output ends of the plurality of radio frequency sensing units 200 are connected to the input end of the control unit 100.

[0041] A plurality of electronic tags, each of which is arranged on a corresponding instrument. Each electronic tag stores the identity information of the corresponding instrument. When the corresponding instrument enters the target area, the radio frequency sensing unit 200 identifies and transmits the identity information stored in the electronic tag to the control unit 100.

[0042] In the embodiments of the present application, the plurality of radio frequency sensing units 200 are finely arranged one by one corresponding to the plurality of target areas on the human body model, and the sensing range is matched with the size of the target area. The control unit 100 identifies the identity information stored in the electronic tag on the instrument through the radio frequency sensing unit 200, so as to accurately identify which specific instrument is used at which specific part of the human body model, which lays a data foundation for subsequent operation compliance verification, intelligent feedback and evaluation, and greatly improves the effect of nursing practical teaching.
