Description

Intelligent control vibration constant-temperature cold therapy rehabilitation wearing device

Technical Field

The invention relates to the technical field of sports medicine, in particular to an intelligent control vibration constant-temperature cold therapy rehabilitation wearing device.

Background

Exercise of varying intensity produces varying degrees of fatigue on the musculoskeletal, neurological, cardiovascular and metabolic systems, and the micro-tears of muscle tissue caused by exercise are commonly described as motor muscle injuries, resulting in delayed muscle soreness, so adequate recovery is necessary to maintain the body's optimum competitive condition during exercise and competition. In the existing recovery means, people mainly advocate a cold therapy mode to improve recovery after physical exercise and achieve unusual effect in practice.

In the cold therapy operation, it has been found that when the prescribed dose and frequency of cold therapy are applied to the muscle mass, the bone, or the like of different parts, the treatment effect is most excellent by using a specific cooling temperature (dose) and a prescribed frequency of treatment, and the cooling temperature range of the treatment may be 0 degrees or more and 0 degrees or less. Because of the influence of human body cold-resisting adaptivity, superficial skin muscle tissues are easy to be cooled, but deep muscles are difficult to be cooled due to cold-resisting stress reactions such as human blood flow increase, and particularly when the cooling rate is low, foreign researches (DeGroot, et al.,2013) indicate that the larger the temperature difference between a medium and a human body is, the larger the cooling rate is, the more obvious the cooling treatment effect of the deep muscle tissues is, and therefore, the cold treatment is more effectively controlled at the low temperature under the condition of zero before the occurrence of cold injury. In the existing cold therapy technology, the local cold compress is directly applied to a patient by using ice water or an ice bag with the temperature of 0 ℃ or above, and the treatment effect of the cold therapy cannot be completely reflected due to the fact that the refrigeration medium is not constant in temperature and the refrigeration quantity is uncontrollable.
