Description

An isolating device for surgical nursing teaching

technical field

The invention relates to the technical field of nursing teaching aids, in particular to an isolation device for surgical nursing teaching.

Background technique

Surgical nursing teaching often involves simulating real scene operations. In order to master various nursing skills, students need to perform real-life manipulations on mannequins, etc. During teaching, when the teacher is manipulating real objects, other students will conduct surrounding observation. When there are too many students, everyone will be fixed in the In one position, it is impossible to see all the action details from multiple angles, and even some people cannot see it. Generally, a screen is used to divide it into multiple spaces, so that students can clearly observe;

However, most of the existing screen devices are straight boards, and the bending angle cannot be adjusted according to the needs of use. The flexibility is poor, and the length is fixed and the length cannot be added according to the demand. In addition, the existing screens Most of the cloth is directly fixed on the frame, and the screen is easy to be contaminated with dust after long-term use, but the screen cloth is not easy to disassemble, and it is inconvenient to replace and clean.
