Evaluation method of ergonomics design of ultrasonic probe

Abstract

The invention relates to an evaluation method of the ergonomics design of an ultrasonic probe. The method comprises the following steps of: demanding a user to simulate ultrasonic detection operation according to the posture and the movement of an ultrasonic doctor in ultrasonic detection; carrying out a specific operation test task by an operator by using ultrasonic probes with different shape designs or weights; recording surface myoelectric signals of a specific hand muscle of the operator by using a myoelectric signal recorder; preprocessing the acquired surface myoelectric signals; then, carrying out the statistical analysis of the amplitudes of the myoelectric signals through pairwise comparison; analyzing whether significant differences to a specific hand muscle load of the volunteer caused by the factors of the shape designs or the weights, and the like of the ultrasonic probes in test operation and using the significant differences as objective evaluation indexes of the ergonomics design of the ultrasonic probe; combining Borg scale subjective comfort score values corresponding to different contrast experiments; and evaluating the ergonomics design of the ultrasonic probe. The method overcomes the defects of a single evaluation index and can comprehensively evaluate the ultrasonic probe.

Description

technical field [0001] The invention relates to an evaluation method of human factors engineering design, in particular to an evaluation method of human factors engineering design of an ultrasonic probe using surface electromyographic signals combined with subjective and objective data indicators of subjective comfort. Background technique [0002] Occupational musculoskeletal disorders are often used to refer broadly to a range of disorders resulting from occupational activities characterized by repetitive movements, prolonged work hours, or forced postures, such as low back pain, arm tremors, shoulder muscle damage, etc. It is generally believed that the static load of local muscles, repeated activities, and the use of poorly designed labor tools during work are the basic causes of musculoskeletal injuries. With the development of technology and the promotion of more advanced ultrasonic testing equipment, the number of cases undergoing ultrasonic examination has increased...

Problems solved by technology

However, the human factors engineering design of equipment has not improved with the improvement of the quality of ultrasonic testing equipment. The result is that some poorly designed equipment has led to the prevalence of occupational musculoskeletal diseases among sonographers.
