Bridge Mechanism Micro-Measurement System Applied to Measuring Mechanical Properties of Muscle Tension

Abstract

The invention discloses a bridge micromeasurement system applied to muscle stretching mechanical performance testing. The bridge micromeasurement system comprises a muscle fixing device, a bridge mechanism, a micro displacement measurement device and a micro force measurement device, wherein the muscle fixing device is used for maintaining preset muscle to be in a physiological state, the bridge mechanism is connected with the muscle fixing device and used for adjusting the preset muscle to be in a relaxation state at an initial moment, the micro displacement measurement device is fixedly connected with the bridge mechanism in an interference fit mode and used for measuring the displacement meeting the stretching scale of the preset muscle, and the micro force measurement device is fixedlyconnected with the bridge mechanism in an interference fit mode and used for collecting stretching force of the preset muscle under different stretch scales. Through the bridge micromeasurement system, the problem that a current muscle testing system can only test the stretching mechanical performance of large-scale muscles of animals and the like is solved, and meanwhile, the problems that the muscle fixing difficulty is large and the physiological activity of the muscle cannot be maintained are avoided.

Description

technical field [0001] The invention relates to the technical field of biomechanical performance testing, in particular to a bridge-type mechanism micro-measurement system applied to muscle stretching mechanical performance testing. Background technique [0002] Insecta plays an important role in biodiversity. It maintains its basic shape through the muscle system. Muscles can convert chemical energy into mechanical energy, which is manifested as the relaxation and contraction of muscle filaments, and all behaviors of insects are realized through muscle stretching And activities, such as crawling, jumping, flying, walking, etc. Under the stimulation of nerve impulses and mechanical tension, muscles can voluntarily contract and produce active tension, and its size is related to the change of muscle length. Insects are the product of evolution in nature, and their good flight ability is closely related to muscle movement. Therefore, it is of great value to study the mechanica...

AI Technical Summary

Problems solved by technology

However, human and animal muscles are on the millimeter scale, while insect muscles are on the micron scale. The existing animal muscle measurement methods cannot measure the tensile mechanical properties of insect muscles.

In addition, muscle is a micron-scale soft tissue, and the existing equipment is cumbersome to operate, not only unable to maintain muscle physiological activity, but also difficult to ensure measurement accuracy
