Spine motion quantity measurement method of medical training dummy with simulated spine

Abstract

The invention discloses a spine motion quantity measurement method of a medical training dummy with a simulation spine. The simulation spine which can be realized easily is designed and the motion characteristics of the simulation spine have a certain similarity to the motion characteristics of the spine of a human body. The invention provides the low-cost measurement method which can be used formeasuring the bending angle and the motion acceleration of the neck, the chest and the lumbar vertebra of the 'spine', thereby providing means for the handling training of spine injuries and the detection of the fixation effect of stretchers and spine fixing apparatuses. The technical scheme comprises the dummy with the simulation spine, a motion measurement and data transmission circuit and a data processing terminal.

Description

technical field [0001] The invention relates to a medical teaching instrument and a medical instrument testing equipment, more specifically, it is a method for measuring the amount of spinal movement which can be used not only for spinal injury handling training but also for testing the fixation effect of stretchers and spinal fixation equipment. Background technique [0002] Improper handling of spinal injuries can easily cause secondary injuries, and severe cases can cause high paraplegia and even life-threatening. Laerdal's nursing model has flexible joints and can be used for patient transfer training; Armstrong Medical Industries' emergency series simulators have a simulated human body size, can be placed in various positions, and have reasonable weights. They are specially designed for the injured in emergencies. Handling and rescue. Domestic companies such as Tianjin Tianyan and Beijing Medical Model also have similar products. At present, this type of product only ...

AI Technical Summary

Problems solved by technology

Due to the large gap in the application background between the car crash test and the handling training, the concerns are also different (the car crash is concerned with the impact on the neck and chest, while the handling training is concerned with the bending angle and acceleration of the neck, chest, and lumbar spine). Crash dummies are expensive and not suitable for handling training

[0004] On the other hand, stretchers and fixation equipment used for handling spinal injuries also lack scientific testing methods to evaluate their fixation and handling effects

Routine tests for this type of product are generally mechanical strength, material properties, etc. Due to the lack of suitable testing methods, there is no scientific method to give a quantitative evaluation of the fixation and handling effects that are related to the safety of patients.
