Description

Equipment and method for cold/hot physiotherapy with fixed depth

Technical Field

The invention relates to the technical field of electronic thermal physiotherapy, in particular to equipment and a method capable of achieving fixed-depth cold/hot physiotherapy.

Background

With the improvement of the physical life of people, the proportion of sub-health people in the people is increasing. At the same time, the pursuit of health and physical aesthetics is also increasing. In order to cope with sub-health conditions such as muscle soreness, torsion loss, cold and hot stiff, pigmentation, etc., more and more methods are being tried, and the approach achieved by means of external devices is becoming the main stream of cold/hot physiotherapy.

The cold/hot physiotherapy of subcutaneous tissues, hair follicles, fat, muscle, ligament, joint and the like is realized by adopting various forms of microwaves, electrons, visible light, infrared light, ultrasound, hot/cold compress and the like, and the cold/hot physiotherapy has the main effects of accelerating blood circulation, preventing pigment deposition, promoting healing, chilblain, collagen stimulation, internal tissue inflammation, slimming and shaping, noninvasive wrinkle removal, skin wrinkle removal, whitening and even inhibiting removal of certain subcutaneous tumor sacs, tumors, hyperplasia, infection and the like.

However, it is inevitable that the body is subjected to a local or wide range of cold/heat treatment during the cold/heat flow process, and during the cold/heat physical quantity input to the deep tissue, a sufficient cold/heat treatment effect is achieved on the target tissue, and an operator must control the freezing/high temperature at a relatively low/high temperature, and add a sufficient freezing/heating time to achieve the input of the corresponding cold/heat physical quantity to the deep tissue and achieve the corresponding physiotherapy effect. However, this process will inevitably result in the human epidermis and dermis systems being subjected to higher intensity, longer duration cold/heat flow treatments. Therefore, the long-time high-strength cold/heat therapy mode can achieve the purpose of physiotherapy, and superficial cells, dermal tissues and the like of a human body can be injured by freezing/heat preferentially, so that serious inflammatory reactions of patients and even skin ulcers and the like can be caused directly.

In the other case, in the heating/freezing operation, it often happens that the therapeutic device lifts off the skin, and at this time, the local contact area is rapidly lowered/raised under the effect of excessive cold/hot flow, so that in the formal physiotherapy process, it is required to ensure that the equipment and the skin of the human body reach good thermal contact degree, and no special cold/hot resistance difference exists between the cold/hot flow applied by the equipment and the body. Otherwise, too fast or too great difference of thermal resistance can lead to extremely uneven cold and hot flow physiotherapy, causing irreversible cold and hot damage to partial deep tissues and epidermis and dermis tissues of the superficial skin of a human body.

Irreversible damage to tissue under supercooling/heating conditions is caused by processes that coagulate, nucleate/denature part of tissue under low/high temperature conditions, and cause membrane damage to tissue structure, dehydration of tissue, denaturalization, etc., which generally require a sufficient period of time to support. In particular, the irreversible crystallization dehydration process of a general tissue under supercooling requires an external factor induction or a sufficiently long freezing time at a low temperature to induce a real crystallization process. There is a related patent document [ patent_l.c.de Bei Nadi kedi ] of a skin freezing system for treating acne and skin conditions, which is directed to an irreversible frostbite mode for realizing directional induction of human tissues by inducing factors such as cryolite condensation nuclei at low temperatures. In the same way, tissue inactivation and dehydration at high temperatures [ 40-50 ℃ also take a certain time to occur. In contrast, if a timely low-temperature interference can be given to the corresponding process in the process, the tissue dehydration process such as irreversible peptide chain and the like can be effectively avoided. Our application was based on the above-described concept.

When the freezing experiment is carried out, the freezing resistance of the skin is ensured as much as possible, and the moisture state of the skin and the link for improving the skin state can be carried out before the thermal physiotherapy is carried out. Specifically, the physiotherapy surfaces of the first and second thermal physiotherapy units are respectively connected with 1K-10 MHz capacitance sensing, micro capacitance values corresponding to the first/second thermal physiotherapy units are detected, when the capacitance value of the corresponding unit area is higher than 100PF/cm ² (the background capacitance is subtracted), and when the capacitance ratio of the first and second thermal physiotherapy units is equal to the external physiotherapy area ratio of the first/second thermal physiotherapy units, the capacitance values are recorded. Furthermore, microcurrent stimulation mode is respectively carried out on the physiotherapy surfaces of the first and the second heat physiotherapy units to activate the superficial skin activity, expand local microcapillaries and improve the cold and hot resistance of the epidermis.

Under the condition of influencing the temperature of the deep hair follicle area, the temperature of the superficial epidermal tissue is quickly restored to a normal active area, and the substantial damage to the superficial tissue caused by continuous heat waiting is avoided.

The first heat energy physiotherapy unit repeats the above-mentioned process, and then the second heat energy physiotherapy unit is tested according to the temperature sensor, and the peripheral physiotherapy range zone is maintained in waiting physiotherapy temperature zone. The physical therapy is actually controlled within 5-10 min. During treatment, the temperature of the physiotherapy surface is 40 ℃, the temperature of the dermis at a position 1mm away from the surface of the skin is 42 ℃, the temperature of subcutaneous 3mm is 45-52 ℃, the temperature of subcutaneous and subcutaneous fat at a deeper depth is reduced to the basal body temperature of 37 ℃, and the temperature of the dermis is reduced to the dermis temperature of approximately 32 ℃.
