Abstract

The invention provides an in-vitro muscle stretching electrical stimulation muscular tension test experimental table. The table comprises a rack, a mobile table, a linear motion unit, an electrode and a program-controlled electrical stimulation instrument. The rack is provided with the linear motion unit, a displacement sensor and the electrode, the displacement sensor is arranged on one side of the linear motion unit which is connected with a servo motor, the servo motor is connected with a motion controller, the mobile table is arranged on the linear motion unit, and opposite muscle clamps are arranged on the rack and the mobile table, one of the muscle clamps is provided with a force sensor, and the electrode is connected with the program-controlled electrical stimulation instrument. By means of the experimental table, experimental muscle bundles can be controlled by a computer to achieve motion in a specific rule, the position of the mobile table can be manually adjusted, so that a changing curve that the force, the stretching length and other parameters of muscular tension are changed along with time when muscle is under different stretching states can be achieved, and an experimental means is provided for researching nerve muscles.

Description

technical field [0001] The invention relates to an experimental equipment for testing the electric stimulation muscle tension of a muscle in a stretched state outside the body, and belongs to the field of medical science experimental equipment. Background technique [0002] Through electrical stimulation of muscles under specific stretching methods, exercise intensity, and duration, and testing the changes in muscle tension, such experimental studies can analyze the relationship between exercise and some muscle diseases, and analyze the effects of different muscle contraction methods on muscle fibers. degree of damage. However, current medical electrical stimulators, muscle tension testing equipment, etc. do not have the function of electrically stimulating muscle tension testing of muscles under specific stretching conditions. Contents of the invention [0003] The present invention aims at the deficiencies in existing analysis techniques for the relationship between exe...
