Embodiment 2
The Position intervention specific embodiment adjusted by air pump is as follows:
(gas device is Mixing and aeration rate air charging system in A Position intervention, carries out controlling different positions by three stage speedsThe aeration quantity for setting air bag is different, so that it is uniformly applied to reach the tilting force acted on the person
(B pressure test device is placed in inside air bag, and in aeration phase, stage detection air pressure inside is if more than default valveValue air pressure then pauses immediately inflation.
(C releasing phase takes classification to deflate using means of deflation, and requiring the rate deflated for different location air bag is notWith, and descending manner user experience is avoided the occurrence of, and it is most to air pressure maximum air bag deflation time, it is scratched to reach blanket each pointDegree uniformly synchronous decline.Preset threshold, first controller " body edge " gas maximum to inner gas pressure at this time are carried out to deflatingCapsule carries out the deflation set time, and detection air pressure at this time continues to deflate if being less than, and if more than stopping deflating, it is adjacent to carry out itsIt is exactly that " second largest " air bag is deflated, same operation is to air bag when inflation Jing Guo aeration phase " minimum ", then in progress " firstReinstatement is known in the air bag deflation second level greatly ", constantly circulation.
(D obtains sound of snoring size, sound of snoring sound source position, user's trunk that pressure sensor obtains by microphone arrayPosition and carry out first step judgement, carry out Position intervention operation if the user if this sound of snoring, otherwise do nothing
(operation of E Position intervention, if detection head position, trunk position with lie on the back sleeping position or prostrate meets, then to userThe air bag contacted with back, buttocks is inflated operation, and it is fourth gear if " body edge " air bag that rate classification, which is inflated,(speed is maximum) rate inflation, is adjacent to third gear, is followed successively by two grades, one grade.This gas replenishment process, which meets B preset pressure valve, can only fitIt answers the sound of snoring strong and weak and changes, so that the torque that the suitable rate suitable period carries out uniform stressed to user makes its adjustmentSleeping position releasing phase is as described in C.
(F Position intervention operation, if detection head position, trunk position meet with lateral sleeping position, then to user and backPortion, buttocks contact air bag be inflated operation, rate classification is inflated, should make if the direction left side of body front its byRight tilting moment operates same E, so that it is tumbled to the left if to the right if body.
(operation of G Position intervention, items detection show that user's sleeping position preference is lain on the back or prostrate is then lain on one's side consciouslySleeping position forms mode, and the accidentally stage intervention that carries out tumbling to it makes its be accustomed to lateral sleeping position, and preferably to make to snore, patient is obtainedTo well sleep.
The Position intervention concrete scheme adjusted by gas generating bottle is as follows:
(the inflation air bleeding mode that A Position intervention uses gas generating bottle to combine with means of deflation, gas generating bottle (figure5) discharge quantity is adjusted by the telescope motor on cylinder piston, it is gas generated by igniting size control, but sent out using gasRaw bottle is the disadvantage is that rate is uncontrollable and the uneven formula that often bursts out, then using classification airing form, subfractionation, with 10 millisecondsThe air pressure preset threshold for setting corresponding air bag is classified for unit, it is maximum to air pressure maximum air bag deflation air pressure, to reach blanketThe uniformly synchronous decline of each point amount of deflection.Controller " body edge " air bag maximum to inner gas pressure at this time first is deflated, warpSpend the small set time, carry out its " second largest " air bag adjacent namely immediately and deflate, same operation to when inflating through gas overchargingThe air bag in stage " minimum " controls the control piston closing of gas generating bottle telescope motor if corresponding air bag reaches preset threshold and fillsGas.Since gas generating bottle rate is too fast, the uniform amount of deflection that " maximum " " secondary greatly " is had adjusted roughly by corresponding " successively " ...
(B is the same as above-mentioned BCD
(operation of C Position intervention, if detection head position, trunk position with lie on the back sleeping position or prostrate meets, then to userThe air bag contacted with back, buttocks is inflated operation, and rate classification is inflated, such as " body edge " air bag, then with above-mentioned AIt is corresponding, it is secondary big ... to carry out opening time successive modes of inflation as maximum
(D is same as above FG
