Description
Technical Field
The invention relates to the field of medical instruments, in particular to an electric pulse generating device.
Background
It has been shown that 63% of all human diseases are spontaneously recovered by the human biological energy, and 21% of the diseases must be treated by drugs. Thus, at the onset of a self-healing illness, physicians often prescribe analgesics to the patient to relieve the pain associated with the illness in the hope that the patient can cure the illness by relying on his or her own bioenergy. However, the administration of analgesics has some problems, and particularly, patients who need long-term analgesia need to take analgesics for a long time, which not only have various side effects caused by the analgesics, but also have dependence and resistance to the analgesics.
In this case, the advent of Transcutaneous Electrical Nerve Stimulation (TENS) has provided a viable solution to the above-mentioned problems. TENS means stimulating nerve and muscle cells of a human body by low-frequency electric pulses with certain intensity, and stimulating the human body to naturally produce analgesic substances to relieve pain caused by diseases. TENS devices used in the prior art mainly comprise: an electric pulse generator, a singlechip and two electrodes in contact with a human body; when the TENS equipment is used, 220V mains supply needs to be connected externally, at the moment, an electric pulse generator generates an electric pulse sequence with certain frequency and intensity under the control of a single chip microcomputer, and the electric pulse sequence is conveyed to a human body through the two electrodes to achieve the purpose of relieving pain. Because the electric pulse generator of the TENS device can normally work only by needing higher voltage, the TENS device is generally powered by commercial power in the prior art, so that the portability of the TENS device is poor, and a patient cannot obtain electric pulse analgesia treatment anytime and anywhere.
