Description

Full-automatic health air cushion bed for preventing bed-sores

This utility model relates to a kind of air fluidized bed, is mainly used in anti-decubital ulcer of bed patient and therapeutic massage.

At present the anti-decubital ulcer utensil that uses of hospital be one as the lifebuoy aerated rubber loop, use inconvenient, can only make local place mat for patient, the patient crouches and can only keep a kind of posture on rubber ring simultaneously, otherwise slides easily, in addition, because patient can not keep the normal flat state that crouches, time has been grown malaise symptoms such as can feeling acid is expanded, numbness, and anti-decubital ulcer effect is undesirable, and patient does not have comfort.

The purpose of this utility model is to provide anti-decubital ulcer effective, has health-care massage function, the all-electronin anti-decubital ulcer health air-pad bed of control automatically.

The technical solution of the utility model is: this utility model is by electronic controller, two air pumps, the A valve, the B valve, in logical valve and the cylindrical airbag of two group leaders constitute, wherein electronic controller is by regulated power supply, the time control circuit and the being used to energy regulator of regulating the air pump energy constitute, the time control circuit respectively with two air pumps, the A valve, the B valve, in logical valve link to each other and control, two air pumps communicate with two groups of airbags respectively and air feed by pipeline, two groups of airbags are alternately arranged successively, during startup by the time control circuit control two air pumps simultaneously to two groups of airbag air feed, two groups of alternately inflations of airbag subsequently, venting, A valve and B valve bump air valve by the normal open electricity and constitute, in logical valve bump air valve by the normal off electricity and constitute.Time control circuit in the electronic controller is made of three " 555 " chips.Two groups of airbags can adopt and amount to 14, and promptly 7 every group, also can increase and decrease as required, two groups of airbags are alternately arranged according to the order of sequence and are placed, and massage by periodically inflation, venting, prevent decubital ulcer.Each airbag is independently.Two air pumps, A valve, B valve, in connect by small hose between the logical valve, airbag.Energy regulator can be made of switch and a plurality of resistance.

Air pump and valve under this utility model is controlled automatically by all-electronin, periodically inflate and make its venting to two groups of airbags, this automatically alternately charge and discharge gas then automatic cycle sexually revise the put forth effort position of human body to mattress, play massage and health-care effect, the scalable aeration speed, and can realize starting first functions such as fast aeration and each circulating energy-saving inflation, have stronger adaptability and modulability, the complete machine energy consumption is low, the life-span is long, comfortable, have the massage effect, can prevent the generation of decubital ulcer effectively.For healthy person, can be used as the massage bed accessory and reach health-care effect.

Further describe this utility model below in conjunction with drawings and Examples.

Fig. 1 is a whole control structure block diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model;

Fig. 3 is a schematic diagram of gas circuit of the present utility model.

Fig. 1 is a control logic block diagram of the present utility model, and Fig. 2 and Fig. 3 reflect overall structure from circuit and gas circuit respectively.In Fig. 2, IC ₁, IC ₂And IC ₃Be " 555 " chip, IC ₄Be " 7812 " chip, ZJ ₁, ZJ ₂, ZJ ₃Be miniature intermediate relay.Work as switch S ₁Closure makes IC by 12 volts of voltages after transformation rectification, filtering, the voltage stabilizing ₁, IC ₂, IC ₃Work simultaneously.IC wherein ₃Finish time-delay and start-up control function first, IC ₃Work makes ZJ ₃Energising, connect PA air pump and PB air pump, logical valve 2 cuts out A valve, B valve simultaneously in opening, make two groups of airbags totally 14 inflations (wherein the odd number airbag is numbered 1,3,5,7,9,11,13, and the even numbers airbag is numbered 2,4,6,8,10,12,14) simultaneously among Fig. 3.Make like this use first or stop using after reuse (because of there not being residual air in the airbag) and can guarantee that this device can transfer user mode to from stored condition rapidly first fast to the airbag inflation.At this moment other delay circuit work is invalid, first start-up circuit IC ₃Monostable time delay is ZJ after 7 minutes ₃Disconnect (IC ₃Just connecting S ₁In time, just start once, delayed time 7 minutes), IC ₁And IC ₂Be in normal operation this moment, because IC ₂Can only delay time for 45 seconds, this circuit has been worked this moment and has been finished, just IC ₁Be in the outage delay time interior (6 minutes) of no stable state, ZJ ₁Have a power failure, make the work of PA air pump, the A valve cuts out, at this moment ZJ ₂Have a power failure make the B valve open, in logical valve Z close, make gas enter the even numbers airbag by pipeline, the PB air pump is not worked simultaneously, and the B valve is opened, the air that has been full of in the odd number airbag is excreted in the atmosphere, odd number airbag volume dwindles because of losing heart, and highly reduces, and the airbag of even numbers simultaneously is then because of inflating continuous expansion, highly raising.IC ₁Behind the delay working 6 minutes, enter another time again and be 6 minutes monostable on-delay state.This moment IC ₂Work ZJ simultaneously ₁, ZJ ₂Energising, A valve and B valve are closed simultaneously, in logical valve Z energising open, PA air pump and PB air pump are worked simultaneously and are inflated to airbag.Because human body weight is even numbers airbag inner air pressure in addition, force air in the even numbers airbag to odd number airbag fast aeration, this part air energy is utilized effectively, so both reduced energy consumption, improved the circulation aeration speed again, reduce the fluctuating quantity of patient on air fluidized bed simultaneously, improved comfortableness; IC after 45 seconds ₂Quit work ZJ ₂Have a power failure IC ₁Work on ZJ ₁Continue energising, the PB air pump is continued to the gas transmission of odd number airbag.At this moment the PA air pump quits work, and the A valve is opened to the atmosphere evacuated air, causes even numbers airbag volume to dwindle because of losing heart, and highly reduces; The odd number airbag then constantly expands simultaneously, highly raises.So circulation, make odd number airbag and even numbers airbag every 6 minutes, inflation and venting respectively, this cycle alternation inflation makes two groups of airbags alternately contact skin, support human body, one group of airbag inflation contact skin, another group airbag venting forms the hole, and the airbag of contact skin is because of periodically alternately oppressing skin, skin had massage effect, the hole that the airbag of venting produces then helps air flows, and airbag charges and discharge the change in volume that gas produces in addition, has quickened air and has flowed, the hot humid gas of skin surface is in time discharged, guarantee the drying and the blood circulation of skin, thereby prevent the generation of decubital ulcer effectively, make the patient of long-term bed exempt the misery of decubital ulcer.In Fig. 2, PA, PB air pump adopt the inductance type air pump, and energy regulator is by switch S ₂And resistance R ₁₀, R ₁₁, R ₁₂, R ₁₃Constitute, adopt energy regulator both to reduce energy consumption, satisfied different weight patient's needs again, improved comfortableness.Adopt two air pump work both can improve aeration speed first, improved each circulation aeration speed again, reduced the degree of heat of components and parts, improve machine life.Be to be connected between the logical valve during air pump, valve reach among Fig. 3 with cross valve.

This utility model is as a kind of effective medical health care products, easily promotes in vast hospital, also be suitable for family as patient with bed or be used for therapeutic massage.
