Abstract

The utility model discloses a DC electrotherapy machine for brains, comprising a DC power supply (1), a constant current source circuit (5) and electrodes (3). The DC electrotherapy machine can cure diseases because of brain blood supply insufficiency such like dizziness, headache, hind neck rigidity, cerebral thrombosis, neurasthenia, etc. The structure of the machine is extremely simple and portable. The DC electrotherapy machine for brains is suitable for medical departments and households.

Description

D C electrotherapy machine for brain

This utility model belongs to the electric pole type galvanization apparatus.

The people is to old, because cerebral blood supply insufficiency causes that easily dizziness, headache, feeling of fullness in the head and collare are stiff, the healthy of old people in serious harm.At present medical department general DL type direct current therapy unit treat above-mentioned disease, not only weak curative effect, and apparatus structure complexity, complex operation, cost height, circuit design are unreasonable.

The purpose of this utility model is that this instrumentation is easy, can carry according to a kind of light, inexpensive, efficient, the safe dc treatment instrument device of brain district organizational structure characteristics design.

This utility model includes two electrode, constant-current source circuit and dc sources that structure is identical.Annexation between them is to be end points with these two electrodes, and constant-current source circuit and dc source are connected in series.Constant-current source circuit is made up of audion, light emitting diode, biasing resistor, current-limiting resistance, potentiometer, and current-limiting resistance, potentiometer, light emitting diode successively are connected in series between the emitter stage of audion and the base stage; Connect biasing resistor between the extremely base of audion and the colelctor electrode; Each electrode is made up of electrode lining cloth, electrode body and electrode pad.

Use this electrizer, general patient after half an hour rheoencephalogram improvement is arranged, a case is arranged, treat a month cerebral thrombosis and disappears, this electrizer also has obvious mitigation to cerebral vasospasm, to the treatment neurasthenia, having a sleepless night has good effect.Because this electrizer is very light, therefore can make hat type, head-clamp formula, tie-type and directly be worn on the head, also can be contained on the spectacle frame, very easy to use, except that for the medical department use, also be a kind of good family health care medical apparatus and instruments.

Below, describe concrete structure of the present utility model and operation principle in detail by drawings and Examples.

Accompanying drawing 1 is the electrical schematic diagram of this electrizer;

Accompanying drawing 2 is structure charts of electrode;

Accompanying drawing 3 is hat type assembling assumption diagrams of this electrizer.

Among the figure, (1) is dc source, can select 12V(5 aneroid battery 8 joints for use) or the 15V(packed cell), (5) are constant-current source circuit, it is by audion BG, light emitting diode D(2); Potentiometer W(4), biasing resistor R ₁With current-limiting resistance R ₂Form, audion BG can select 3CG type or 3DG type for use, and light emitting diode D can select LN21 for use, and potentiometer W span is 4.7K Ω～100K Ω, R ₁Be 10K Ω～100K Ω, R ₂Be 100 Ω～500 Ω, in accompanying drawing 1 and accompanying drawing 3, light emitting diode D is expressed as (2); Potentiometer W is expressed as (4), (3) be electrode, its structure is divided into (8) three layers of electrode lining cloth (6), electrode body (7), electrode pad, contact conductor (9) is drawn with circuit by an end of electrode body (7) and is connected, electrode body (7) can select for use metal otter board to make, and electrode pad (8) can select for use artificial leather to make.

Accompanying drawing 3 has been drawn the embodiment of this brain direct current therapy unit, and it is that circuit bank is contained in the medicated cap, becomes the electrizer of cap structure.Concrete assembling is: two identical electrodes (3) of structure are contained in respectively on the position, front and rear part of medicated cap mouth (11), light emitting diode (2) is contained on the shade (12), dc source (1) with 15V packed cell and remaining element be assemblied in that wiring board (13) is gone up, wiring board (13) is contained in the middle of the two layers of cloth of medicated cap body (10), and the handle that makes potentiometer (4) is exposed at outside the medicated cap body (10), be convenient to adjust output current, output current intensity can be adjustable continuously at 0.2mA～3mA.

The operation principle of this brain direct current therapy unit is: after this machine is worn on the head, energized, because head closely contacts with two electrodes (3), head makes circuit constitute series closed circuit as working media, light emitting diode (2) is bright, circuit working, the constant current that constant-current source circuit (5) produces passes head by electrode (3); According to DC current the enhanced function of the metabolism that makes biological tissue is arranged, the blood flow of head energization area is increased, reach the disease that treatment causes because of cerebral blood supply insufficiency.

Claims

1, a kind of brain direct current therapy unit, include two electrodes (3) that structure is identical, it is characterized in that also containing constant-current source circuit (5) and dc source (1), annexation between them is to be two-end-point with two identical electrodes (3) of structure, constant-current source circuit that is connected in series (5) and dc source (1).
