Abstract
The utility model relates to a mattress for preventing bedsore, which belongs to the medical device. The utility model comprises mattress surfaces and is characterized in that a plurality of air bags are arranged between the mattress surfaces; the air bags are connected with an air pump through an air tube and an electromagnetic valve; the air pump and the electromagnetic valve are controlled by an electrical automatic control device. The utility model can effectively prevent bedsore and had the advantages of simple structure, etc.
Description
This utility model is to belong to medical apparatus and instruments.
Hospital takes regularly to stand up to the patient to change position or regularly change the generation that pad prevents decubital ulcer usually at present, in addition, also will give the compression zone bit timing manual massage of health; This has not only increased misery to the patient, has also increased trouble to the entourage.
The purpose of this utility model is exactly at the problems referred to above, provides a kind of and can change health pressurized position automatically, the pressurized tissue can be interrupted alternately obtain blood circulation, effectively prevents the pad that decubital ulcer takes place.
The purpose of this utility model is achieved in that this utility model comprises the cotton-padded mattress face, and its structural feature is to have a plurality of air bags between the cotton-padded mattress face, and air bag links to each other with air pump by trachea, electromagnetic valve, and air pump, electromagnetic valve are controlled by electrical automatic control equipment.
Major advantage of the present utility model:
1, can effectively prevent the generation of decubital ulcer:
Because this utility model is provided with a plurality of air bags, and is controlled by automatic control electric device, make air bag support human body by the time of people's setting, the position of setting, just can be equivalent to regularly stir, change pressure spot, effectively prevent the generation of decubital ulcer:
2, simple in structure:
This utility model mainly is made up of cotton-padded mattress face, air bag, air pump, electromagnetic valve, automatic electric control device, and it is simple in structure, and cotton-padded mattress face, air bag need outside special the making, and all the other all can be purchased from market, so processing technology is also simple.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an electrical automatic control equipment schematic diagram of the present utility model.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:
The utility model comprises cotton-padded mattress face 8, has a plurality of air bags 6 between the cotton-padded mattress face 8, and air bag 6 passes through tracheae 4, magnetic valve 1 links to each other with air pump 2, and air pump 2, magnetic valve 1 are controlled by electrical automatic control equipment 3 System.
Electrical automatic control equipment 3 of the present utility model is technology that those of ordinary skill is easily implemented, and electrical automatic control equipment 3 of the present utility model comprises the clock ic chip1(for example, model is TW1943), with the door ic chip2(for example, model is 74087) bistable circuit W, controllable silicon T1、T

Through transformer T step-down, three windings of inferior fraction, winding one are 20 volts, after rectifier D, integrated package 7812 voltage stabilizings by civil power, and one the road supplies with the clock ic chip 123 jiaos and 12 volts relay, another road is supplied with and a door ic chip through integrated package 7805 step-downs2(for example, model is 7408) and bistable circuit W (for example, Model is 74LS160); Winding two is 30 volts, triggers relay for magnetic valve 1 and bistable state after the halfwave rectifier Device; Winding three is 5 volts, and an end string has 100 kilohms of resistance and clock ic chip135 pin link to each other, Pulse signal source when walking with 50 hertz.
The clock ic chip1Export the high level that showed stroke in 0-12 hour, control air pump 2 after amplifying , magnetic valve 1, reach regularly the purpose to air bag 6 inflation/deflations, specifically with changed in 0-12 hour the time Between data signal realize the programme-control of relay. Illustrate take relay as clue that below this is electric automatically The operating principle of control device:
Relay J2Working signal be taken from 1-12 hour digital stroke " E " signal (the 9th pin) because " E " section even number time is all exported high potential such as 12,2,6,8,10, be added in triode G2Base stage on, amplify the rear drive relay J2Action, from numeral " E " section output electronegative potential of " 4 " word as can be known, utilize F and the G stroke of " 4 " word to make signal source (because all export electronegative potential in F, the G section of 12,1,2,3 these several bit digital, only having " 4 " word F, G section is high potential), F and the G stroke of 4 words is added in and the door ic chip2Input, just obtain at output A high potential. For preventing " 5 ", " 9 " misoperation, when arriving, " 5 " word disconnects and door IC2Output be provided with relay J1。
Relay J1Action depend on controllable silicon T1, but controllable silicon T1Negative pole with triode G3Link to each other, only have triode G3When saturated, controllable silicon T1Could connect triode G3Base stage be connected controllable silicon T with the b of digital stroke1The control utmost point link to each other relay J in fact with 10 hours b, c numeral stroke1Just adhesive in 10,11,12,1,2,3,4 hours, only when " 4 ", with the door ic chip2Just export high potential. Relay J1Disconnection, be " b " stroke no-output of utilizing numeral " 5 ", when the b of " 5 " section is electronegative potential, triode G3Cut-off, controllable silicon T1, relay J1Disconnect.
Relay J
3Be with normally-closed contact control air pump 2, electromagnetic valve 1 work, when energising, air pump 2 work, i.e. gas injection, the length of its time is by selector switch K
1Decision, when selecting 1 minute, controllable silicon T
2The control utmost point and audion G
1The colelctor electrode of (phase inverter) joins, audion G
1Base stage be high level, current collection is low level, controllable silicon T very
2End, when numeral F section when " 0 " jumps to " 1 " is a low level, audion G
1Base stage low level, current collection high level very, controllable silicon T
2Conducting.As button K
1When selecting 2 minutes, controllable silicon T
2The control utmost point directly link to each other by resistance with a G section that minute shows, the G section is high level, controllable silicon T when showing 2 minutes
2Conducting.
Postpone attracting electric relay T
5Effect be to make relay J
3When the selected working time reached, adhesive reliably disconnecting reliably again in a flash of adhesive, for prepare next time, postponed attracting electric relay and is subjected to relay J
