Abstract

The utility model provides an electrotherapy blanket which comprises a blanket body and an electro-therapeutic apparatus. A plurality of pairs of positive contact electrodes and negative contact electrodes connected with the output end of the electro-therapeutic apparatus are arranged on the blanket body, the electro-therapeutic apparatus is composed of a pulse generating circuit, a circular gating control circuit for controlling circular breakover of the contact electrodes, a contact electrode drive circuit and a power supply circuit. The circular gating control circuit is formed by connecting a frequency divider and a counter and controls the contact electrodes to be sequentially connected in turn and output electric pulse signals adapting to human body feeling. When people lie on the backs, lie prostrate or lie on the sides, the contact electrodes of the electrotherapy blanket are directly contacted with the body skin and output the electric pulse signals which the people can adapt to, and the purposes of relieving discomfort and performing overall physical therapy are achieved.

Description

Electrotherapy pad blanket

Technical field

The utility model relates to the pad blanket, in particular the blanket of electrotherapeutic function.

Background technology

Blanket mainly contains damp proof insulation, thermal effect; But say from actual functional capability; Increase electrotherapeutic function, let it have the function of use that is more suitable for comprising electrotherapy, on suitable degree, exempt the handicapped burden that also must regularly go hospitalize of patient in patient's enforcement of suffering from pain in waist and lower extremities, backache, shoulder pain; And can utilize spare time at night or other time of having a rest to carry out electrotherapy, to alleviate daily discomfort.

Summary of the invention

The goal of the invention of the utility model is to provide a kind of electrotherapy pad blanket with electrotherapeutic function.The electrotherapy pad blanket technical scheme that the utility model provides; Its major technique content is: a kind of electrotherapy pad blanket; Comprise pad blanket and electro-therapeutic apparatus; The some of electro-therapeutic apparatus are filling up on the blanket positive and negative contact electrode arranged; Electro-therapeutic apparatus is made up of circulation gating circuit, contact electrode drive circuit and the power supply circuits of pulse generating circuit, each contact electrode circulation conducting control, and the circulation gating circuit is connected and composed by the frequency divider sum counter, and the decoding output of counter is connected the contact electrode drive circuit respectively through backward dioded with the pulse output end parallel connection of pulse generating circuit and by putting in order.

The disclosed electrotherapy pad of the utility model blanket technical scheme; Because of each contact electrode arranged distribution on the bigger fabric pad blanket of area; The people lie on the back, prostrate or when lying on one's side, the body skin directly is contacted with each contact electrode, each contact electrode is in proper order open-minded in turn down in the control of circulation gating circuit; The electric impulse signal that output and human body sensory adapt; Basically be to walk always to act on corresponding acupuncture by collaterals of human, it can simulate amplitude, frequency and the frequency that the massage rhythm and pace of moving things of staff and intensity that patient can adapt to are regulated the output pulse, reaches the purpose of alleviating uncomfortable whole electrotherapy.

The specific embodiment

The disclosed electrotherapy pad of the utility model blanket; Comprise pad blanket and electro-therapeutic apparatus; Electro-therapeutic apparatus output is connected with the two ten pair positive and negative contact electrode 1-20s of vertical arrangement fixed and arranged on the pad blanket, and the arrangement of these contact electrodes is as shown in Figure 1, and contact electrode all is the gentle matter conductive silicon rubber electrodes of the spaced apart bar shaped of horizontal expansion; Can be folding with the pad blanket, wherein the layout quantity of contact electrode also can increase or reduce according to actual needs.

The circuit of electro-therapeutic apparatus constitutes as shown in Figures 2 and 3, include output treatment pulse pulse generating circuit, control each circulation gating circuit that the contact electrode rotation is opened, contact electrode drive circuit and power supply circuits and constitute.Powerup issue when solving no industrial frequency AC civil power, these power supply circuits are power supply with the battery, cell voltage is boosted to be reached more than the 30V, required to satisfy result of treatment.With No. 5 batteries of four joints the 5V supply voltage being provided is example, and power supply circuits are booster power supply circuit, in the present embodiment; As shown in Figure 2, these power supply circuits are made up of MC34063 pressure regulation integrated chip IC1 and peripheral components thereof, and the design of 5V cell voltage is promoted to 60V; Its output is connected with the square wave regulating circuit by voltage-stabiliser tube D2, D3 and potentiometer W1 parallel connection; Two voltage-stabiliser tube D2, D3 have set the range of regulation of 6-60V for potentiometer W1, if can be connected in the industrial frequency AC civil power, for compatible battery uses; The voltage stabilizing of power supply circuits set inside is to the voltage stabilizing chip of 5V, and the output of voltage stabilizing end connects booster power supply circuit.The circuit constituted mode of pulse generating circuit is a lot; In this structure; To select for use two NAND gate IC2A, IC2B among the four NAND gate buffer chip CD7402 to connect and compose oscillator is example; Branch road is provided with potentiometer R6 between two NAND gate IC2A, the IC2B, adjustment oscillator output pulse frequency in the 0.5Hz-10KHz scope of setting, and the output of pulse oscillator links to each other with the input of other two dual input NAND gate IC2C, IC2D respectively.The circulation gating circuit is connected and composed by the frequency divider sum counter, and frequency divider is connected and composed by CD4541 chip IC 4, to the clock end clock signal of counter IC5; Each decoding output of counter IC5 connects the contact electrode drive circuit, in the present embodiment, because contact electrode quantity is many; Need counter chip is adopted port expansion circuit, expand to 20 output lines, to save circuit resource; The port expansion structure is a lot, provides an embodiment to cast a brick to attract jade at this.20 pairs of contact electrodes are divided into upper and lower distribution two groups; Each decoding output of counter IC5 connects two-way backward dioded V1-V10; Wherein one road backward dioded is linked in sequence to the first groups of contact electrode drive circuit; Another road backward dioded second groups of contact electrode drive circuit that is linked in sequence, the carry end CO of counter IC5 is connected with trigger IC3, and two outputs of trigger IC3 are connected on another input of two dual input NAND gate IC2C, IC2D; The output signal of trigger output signal and impulse generator mutually " with " afterwards parallelly connected with the output of pulse generating circuit, be connected to the input of contact electrode drive circuit again.Counter is pressed the clock signal in frequency divider output cycle and is controlled down chronologically; Step sequence is exported high level in turn and is opened connected drive circuit, and remaining drive circuit is blocked by low level, by the driving tube amplification of drive circuit; Output amplitude reaches on the positive and negative contact electrode that the treatment pulse signal is given with its output is connected of 6-60V; Under next frequency divider control cycle control, make down or go up a pair of contact electrode conducting, so order is back and forth.
