Problems solved by technology

[0004] However, in the prior art, the drug iontophoresis therapeutic instrument and the interference electrotherapeutic instrument are two separate therapeutic instruments, which have a single function and high production cost, and are only suitable for use in hospitals and high-income groups, and are difficult to popularize in ordinary people. income family
In addition, most of these instruments are implemented by analog circuits at present, which makes the adjustment inflexible and the output cannot be diversified.

Abstract

The invention discloses a medication ion infusion and interference electricity multifunctional therapeutic instrument, which is provided with a control unit, a DA converting circuit, a proportion amplifying circuit, an adder, a sinewave generating circuit, a waveform modulation circuit, a power amplifying circuit and an isolating output circuit which are connected in turn, wherein the output of the control unit is also connected to the waveform modulation circuit; the output of the DA converting circuit is also connected with the waveform modulation circuit and the power amplifying circuit respectively; an adjustable voltage is connected to the adder; and the control unit adopts a singlechip to control the conversion of therapeutic modes, four waveforms of the medication ion infusion, difference frequency of the interference electricity and generation of modulation waves. The multifunctional therapeutic instrument uses the singlechip for control and adjustment, and simultaneously adopts a power output circuit to realize two different physical therapeutic modes, namely the medication ion infusion and the interference electricity, so the instrument is more convenient to adjust, has more functions, reduces the production cost, and is favorable for popularization in common families. Each therapeutic mode has a plurality of output waveforms so as to prevent the human body from generating adaptability in use.

Description

technical field [0001] The invention relates to a medical treatment instrument. In particular, it relates to a drug iontophoresis and interference electric multifunctional therapeutic instrument which is convenient to use, has diversified functions, and greatly reduces production costs, which is beneficial to popularization in ordinary families. Background technique [0002] Drug iontophoresis technology is a method of using an electric field to introduce drug ions into the human body through the skin, mucous membranes or wounds to treat diseases. The principle is that certain drugs in the drug ion solution can be dissociated into ions, and under the action of a direct current electric field force, the charged drug ions produce directional movement. It has been used as a physical therapy for more than 200 years. However, in 1990, Leudc introduced the term "iontophoresis" and basically shaped the iontophoresis device. Afterwards, extensive research was carried out on instr...
