A labor-saving current regulating device for an electrotherapy instrument

Technical field:

The invention belongs to the technical field of current regulation of electrotherapy instruments, and relates to a labor-saving current regulation device for electrotherapy instruments, in particular to a device that can adjust the current through the human body according to the different tolerance levels of different parts of different subjects. s installation.

Background technique:

There is a unique electric current in the human body. For example, every part of the human body, such as the human heart, brain, muscles, and nerves, will emit a very weak bioelectric current that cannot be felt by itself. Bioelectric current plays an important role in the normal operation of body functions. It plays a very important role, especially for the coordinated operation of cells, nerves, and meridians in the human body. Modern scientific research has confirmed that if the operating functions of the meridians of the human body are blocked by external factors, the circulation of Qi and blood in the human body will also be blocked. Similarly, if the potential of nerve cells in the human body is unbalanced, the resistance will increase, the current will be blocked, and the electrical signal will be transmitted. Blockage can also cause pain in related nerve nuclei and tissues.

Electrotherapy is to connect pulsed electrical signals of a certain voltage and frequency to the human body through electrodes. Since many components of human tissue have certain electrical characteristics, when receiving electrical stimulation, the muscles, nerves, body fluids, and blood of the human body will produce A certain degree of physical and chemical reactions. The existing technology has designed an electrotherapy instrument, which applies a certain frequency of current to the meridians of the human body, especially a current that is the same as or slightly higher than the frequency of the human body's own biological current to adjust the biological current in the human body, so that it can be balanced, so as to achieve therapeutic effect. effect; in the course of treatment, the current will be adjusted according to the tolerance of different parts of the subject, and once the electrotherapy instrument is produced, its output current is a fixed value or has several current gears for selection, which is not suitable Due to the different tolerance levels of the subjects or different parts of the subjects; during the treatment operation, the operator needs to adjust the current button on the electrotherapy device while treating, which affects the treatment progress, which is very inconvenient; currently there is another The method of implementing electrotherapy, one electrode of the electrotherapy instrument is connected to the sponge with water, the other electrode is placed on the body of the subject, the physical therapist steps on the sponge with water with bare feet, and the current is transmitted to the body of the subject through the hands of the physical therapist , and perform physical therapy, but if the body resistance of the subject is inconsistent with that of the physical therapist, the physical therapy effect on the subject will not be good, and the physical therapist will be subjected to electric current stimulation beyond its own carrying capacity, causing physical discomfort to the physical therapist And physiological abnormalities, and the scene of the physical therapist stepping on the sponge with bare feet is also unsightly; the foot-operated current regulating device has only one sliding column and a pedal, and can only be stepped on with one part of the foot, which easily makes the operator fatigued. Therefore, it is necessary to design a labor-saving current regulating device for an electrotherapy instrument. The current regulating device is set on the sole of the foot to adjust the current size, and two pedal parts are set so that the sole and the heel of the foot can be stepped on alternately, so as to relieve operator fatigue, save time and effort, and be easy to operate. Reliable, improve the effect of physical therapy, reduce physical discomfort and other conditions of the physical therapist.
