Abstract

The utility model discloses a pneumatic muscle stretching or bending apparatus, belonging to a rehabilitation appliance. Paralysis limbs can be driven to do the stretching and bending actions. The pneumatic muscle stretching or bending apparatus has the advantages of promoting promote blood circulation, preventing muscle amyotrophy, recovering the function of the limbs, health care and eliminating fatigue. The pneumatic muscle stretching or bending apparatus mainly comprises an air supply, an electric change valve, a relay and an air bag. The utility model has strong target, and can be used for each part of the human body with simple structure and convenient carryover.

Description

Pneumatic muscle stretching or bending apparatus

This utility model relates to a kind of muscle driving device, and it can drive paralyzed limbs and finish action in the wrong, the effect of playing blood circulation promoting, preventing amyotrophy, recover limb function of stretching.

Existing rehabilitation or health and fitness facilities mainly divide two kinds: power type and physical type.More power type utilizes electricity to drive human body such as is massaged, vibrates, beats at stimulation, can improve the local blood circulation of human body, but the effect that does not have the function of exercising one's muscles owing to do not have directly to drive limbs.Other has a kind of pulse generator, can cause the contraction that muscle is slight, but is not that effect is different with limb motion with induced way equally.Physical type comprises various health and fitness facilitieses, as running fitness equipment, multi-gym etc., is characterized in toning up the muscles, but will leans on user self execution of having an effect, and this obviously is unsuitable for the paralytic that limbs can't be moved.Still do not have so far and a kind ofly can drive the easy apparatus that paralyzed limbs is finished exercises, the patient has to do by other people in treatment and rehabilitation course and finishes functional exercise, and is not only very inconvenient, and consumes very much operator's muscle power.

This utility model aims to provide a kind of simple in structure, pneumatic type muscle driving device that can drive each main muscle of whole body, and its basic acts is to stretch in the wrongly, is mainly used in the function of recovering paralyzed limbs.

This utility model is achieved in that it mainly is made up of source of the gas, electric reversal valve, relay, air bag; Source of the gas output enters electric reversal valve during work; Relay is an actuating signal with the output pressure, controls electric reversal valve valve core of main valve and is shifted at regular intervals once, opens or close working hole, finishes gas transmission, aerofluxus action.The delivery outlet of air bag and electric reversal valve and air vent join and are bound by on the limbs, and expansion, strong during inflation drives limbs; Weak when losing heart, loosen limbs.Design action is determined that by bladder shape air bag can be designed to multiple shape one cover, replaces mutually, also can be designed to an air bag and have multiple shape (or some air bags integrally combine), adjusts the valve distortion.In order to keep the bag volume unanimity of different size, can in than air vesicle, fill the soft foam inner tube of a tyre that has air chamber, to dwindle volume.This utility model has mainly utilized bladder shape to change principle and the gravity principle that produces displacement.

This utility model is different from other rehabilitation appliances because of having the ability that drives limbs; Finishing difference because of difform air bag moves flexible, practical; Simplified frame for movement because of having taked pneumatic type; Because of the operating part air bag is that software is easy to carry.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the pneumatic diagram of this utility model power section.

Fig. 2 is the side view (during inflation) of air bag in this utility model.

Fig. 3 is a difform air bag situation in use in this utility model.

Among the figure: (1) source of the gas; (2) electric reversal valve; (3) relay; (4) air bag; (5) degree of tightness band; (6) flexible pipe; (7) threeway; (8) lead to the pipeline of reversal valve delivery outlet; (9) lead to the pipeline of reversal valve air vent.

Present embodiment adopts air compressor to do source of the gas (1), and the electric reversal valve of automatically controlled normally closed (leading to) cut-off type of two-position three way list is made reversal valve (2) (hereinafter to be referred as reversal valve), and pressure switch is made relay (3).Among Fig. 1, the air inlet O of the delivery outlet of air compressor (1) and reversal valve (2) joins, pressure switch (3) and electric joining of reversal valve (2).Among Fig. 2, the flexible pipe (6) of air bag (4) is through threeway (7) branch, and one (8) lead to the delivery outlet A of reversal valve (2), and another (9) lead to the air vent P of reversal valve (2).Pressure switch during work (3) control reversal valve (2) valve core of main valve is shifted once at regular intervals, opens or close delivery outlet A, finishes gas transmission, aerofluxus action; The action of pressure switch (3) is arranged by output pressure.Constantly inflation of air bag (4), disappointing produces reciprocating motion, drives and stretches in the wrong by the limbs of its degree of tightness band (5) constraint.Air bag (4) can be designed to different shapes as required, by its shape decision action.Air bag (4) can be multiple shape one cover, mutual alternative, also can be an air bag (4), multiple shape, by the mutual conversion of adjustment valve.For the air bag (4) of large-size, the soft foam inner tube of a tyre that has air chamber can be filled in inside, to dwindle volume, to keep all air bags (4) volume unanimity.The operating frequency of air bag (4) is advisable for 30～60 times to be adjusted in the per minute kind.Among Fig. 3, a is the situation that this utility model drives biceps brachii m., and b is for driving the situation of quadriceps femoris, and c as long as user is prostrate, just can drive lumbodorsal muscle for driving the situation of rectus abdominis m. among the c.

Claims

1, a kind of muscle driving device, it is characterized in that: it mainly is made up of source of the gas, reversal valve, relay, air bag, and the delivery outlet of source of the gas and the air inlet of reversal valve join, and reversal valve and relay join; The flexible pipe of air bag is through threeway branch, a delivery outlet that leads to reversal valve, and another leads to the air vent of reversal valve.

2, according to the described muscle driving device of claim 1, it is characterized in that: be filled with the soft foam inner tube of a tyre of band air chamber in the air bag of difformity and size, to keep all bag volume unanimities.
