The specific embodiment

Medical bed mattress is as shown in Figure 1 and Figure 2 fixed on heelpiece 16 by some airbags 17 arrangements and forms the mattress with certain thickness and volume, each airbag 17 is separated into upper chamber 6 and lower chamber 7 at middle part by airbag separate layer 8, and each upper chamber 6 and each lower chamber 7 are connected with respectively trachea.

Upper chamber 6 is alternate is divided into two groups, wherein the trachea of one group of upper chamber 6 is communicated with A group air chamber trachea 4 jointly, the trachea of another group upper chamber 6 is communicated with B group air chamber trachea 5 jointly, and A group air chamber trachea 4 and B group air chamber trachea 5 are communicated with respectively inflation gas exhausting valve 3, and inflation exhaust controller 3 connects air pump 2.Inflation gas exhausting valve 3 is alternately inflated and aerofluxus A group air chamber trachea 4 and B group air chamber trachea 5.

The trachea of lower chamber 7 is connected respectively to lower chamber group trachea 14, and lower chamber group trachea 14 connects charging check valve 9, and charging check valve 9 front ends connect air pump 2.

The power supply of air pump 2 and inflation exhaust controller 3 is controlled by micro-computer controlled device 1, between inflation exhaust controller 3 and air pump 2, in connecting pipe, is connected with pressure transducer 10.When mattress is used, patient crouches on mattress, air pump 2 starts and provides air to A group air chamber trachea 4, B group air chamber trachea 5 and lower chamber group trachea 14 simultaneously, after mattress has pressurizeed, stop air pump 2, micro-computer controlled device 1 starts inflation exhaust controller 3, carries out a small amount of aerofluxus of several times, the pressure data that records by pressure transducer 10 is transferred to micro-computer controlled device 1, and micro-computer controlled device 1 calculates the setting air pressure that is applicable to patient body weight.Mattress is normally worked subsequently, chamber inflated exhaust controller 3 carries out inflation and aerofluxus alternately to A group air chamber trachea 4 and B group air chamber trachea 5, upper chamber 6 alternately forms the action of inflation and aerofluxus, the massage that patient body is pushed and loosened, thus patient's decubital ulcer is prevented and treated.Pressure transducer 10 is monitored inner gas pressure at any time, and inner gas pressure reaches while setting air pressure, and micro-computer controlled device 1 is to air pump 2 power-off, and air pump 2 quits work.

The manual rapid escape valve 11 that connects A group air chamber trachea 4, B group air chamber trachea 5 and lower chamber group trachea 14 is provided at the end of mattress, patient, occur being critically ill and need to implement that artificial respiration, operation etc. are rescued and treatment measure in the situation that, open manual rapid escape valve 11, can be by whole the air in airbag 17 fast evacuation, avoid hindering the enforcement of rescue and treatment measure.Manually having rapid escape valve power supply gang switch 13 on rapid escape valve 11, when opening manual rapid escape valve 11, cut off the power supply of air pump 2.Manually the exhaust end of rapid escape valve 11 can connect negative pressure exhaust interface 12, is convenient to connect the standby negative-pressure pipeline of hospital, makes the aerofluxus of airbag 17 quicker.

Shown in Fig. 3, Fig. 4, Fig. 5, manually rapid escape valve comprises valve seat 21, and the front end of valve seat 21 has pump-line interface 22, and there is flap shutter 23 base 21 rear ends, there is exhaust duct holder 24 flap shutter 23 rear ends, and exhaust duct holder 24 has the exhaust duct 25 of some connection mattress exhaustors.The periphery of flap shutter 23 has connecting ring 26, connecting ring 26 and base 21 rear end correspondences respectively have the concavo-convex circle of ring-type, between connecting ring 26 and valve seat 21, by the concavo-convex snare of corresponding ring-type, close connection, make thus connecting ring 26 relatively rotate, and drive flap shutter 23 to rotate.There is rotating shaft 27 centre of flap shutter 23, there is axis hole 32 centre of exhaust duct holder 24, there is spring mounting hole 33 in the outside of axis hole 32, rotating shaft 27 is enclosed within this axis hole 32, there is Compress Spring 28 outer end of rotating shaft 27, one end of Compress Spring 28 withstands on axis hole 32 outsides, and the other end is fixing by the trip bolt 29 of rotating shaft 27 outer ends.On flap shutter 23, have the some through holes 30 corresponding with exhaust duct 25, the front end of each exhaust duct 25 respectively has seal washer 31.By the tension force extruding of Compress Spring 28, the seal washer 31 of each exhaust duct 25 front ends can be close to flap shutter 23, makes each exhaust duct 25 in closed state.While opening, rotate flap shutter 23, each through hole 30 on flap shutter 23 can be aimed at each exhaust duct 25 simultaneously, each exhaust duct 25 is opened simultaneously, and the air in mattress is found time rapidly by the negative-pressure pipeline of hospital by pump-line interface 22, thereby realizes Quick air-discharge.

In the situation that occurring that airbag insufficient pressure, power-off, inflation and aerofluxus are broken down, micro-computer controlled device 1 provides alarm signal, and indicating alarm device 15 sends alarm signal.
