This utility model is at clinically the prevention of decubital ulcer not being had a kind of device of a kind of not only economy but also practicality (being adapted at China's large scale application) now and designing.Its functional characteristics is that mattress is made up of two groups of several air bags that are spaced together, there is certain pressure differential the alternately inflation respectively of these two groups of air bags, aerofluxus in both, make the conversion of health compression zone bit interleaving like this, the health compression face is reached the effect of massage, blood circulation promoting prevents that decubital ulcer from taking place.
Its whole structural scheme of mechanism of this utility model multifunction simple anti-bedsore mattress is seen accompanying drawing 1.
Description of drawings:
Accompanying drawing 1 is a low-pressure for (1) group air bag, working state schematic representation when (2) group air bag is high pressure.
Accompanying drawing 2 is mean pressure (hyperbar+low pressure)/2 o'clock working state schematic representation for (1) group, (2) group air bag.
Accompanying drawing 3 is a high pressure for (1) group air bag, working state schematic representation when (2) group air bag is low-pressure.
Below parts, device and the above accompanying drawing of overall work combinations of states that constitutes technical characterictic of the present utility model is described in detail:
1. mattress (seeing accompanying drawing 1)
This mattress is to organize several air bags interval parallel arranged by two groups (1) group and (2) to become mattress, each air bag of every group is drawn an airway, accumulate airway (3) and (4) then respectively, airway (3) is divided into two again and is in charge of (13) and (14).Airway (4) is divided into again is in charge of (11) and (12).
As accompanying drawing 1, when the interior pressure of several air bags that (2) are organized was high pressure, this group air bag was big to patient's body-support power, and the pressure in several air bags of (1) group is low pressure, and is little to the support force of human body.As accompanying drawing 3, when the pressure in several air bags of (1) group became high pressure, this group was big to patient's body-support power, and several air bags of (2) group become low pressure simultaneously, and is little to the support force of human body.Timing hockets like this, can reach to prevent that decubital ulcer from taking place.
As abundance gas, this moment can be with airway (4) and (3) connection as the family life mattress, after giving two groups air bag sufficient gas respectively, with the closed catheter of each air bag, can can not cause danger because of indivedual air bags damage gas leakage this moment as the swimming pad.
2. controller (seeing accompanying drawing 1,2,3)
This controller is made up of gas switch (7), high pressure valve (5), low-pressure valve (6), unidirectional guide valve (10).6 gas ports are housed on the outer wall of gas switch (7), (15), (16), (17), (18), (19), (20), wherein (15), (17), (18), (19) five equilibrium garden week, (20) be positioned in the middle of (19), (15), (16) are positioned in the middle of (15), (17).(15) communicate with (11) with (33), (20) with (14), (19) with (6), (18) with (13), (17) with (12), (16).The switch of gas switch (7) has two airways (8), (9) in the heart, and they each have two adjacent holes, branch garden weeks such as this four hole.
High pressure valve (5) can have nut (22) to regulate the pressure of pressure spring (23), and making the pressure in the high pressure valve is high pressure (high pressure of regulation).When the gas pressure in the pressure valve has surpassed the high pressure of regulation, valve core (21) is pressed towards the outer steam vent (24) that surpasses, gas is discharged from (24), the valve internal pressure drop to the high pressure of regulation when following valve core (21) rebounded by (23), maintain in the high pressure range of regulation thereby regulate the pressure that makes in the high pressure valve.The operation principle of low pressure valve (6) is identical with high pressure valve, and just low pressure valve is kept in the low pressure range that is pressed in regulation in it.Unidirectional guide valve (10), its function are that gas can only advance in (33) from guide valve (10).
When gas switch (7) was in accompanying drawing 1 state, two holes of airway (8) communicated with (15) and (17) respectively, and two holes of airway (9) communicate with (18) and (19) respectively.This moment gas from (10), (33), (19), (9), (18), (14), (3) give (2) group airbag aeration, cause pressure to reach the high pressure of regulation, during as its intrinsic pressure regulation high pressure that has surpassed high pressure valve, gas is discharged from (24).Prevent because of inflating the excessive air bag explosion that makes.When being in the state of accompanying drawing 2 as gas switch, two holes of airway (8) communicate with (20), (16) respectively, and airway (9) is a dead space.Gases at high pressure in (2) group air bag enter in the low pressure air bag (1) by (3), (13), (16), (8), (20), (11), (4) at this moment, making the pressure in two groups of air bags is that mean pressure (high pressure+low pressure)/2 can be saved source of the gas air feed (mean pressure-low pressure) like this, then gas switch is transferred to the duty of accompanying drawing 3, two holes of airway (8), (9) communicate with (15), (19), (17), (18) respectively at this moment.(2) the mean pressure gas in the group air bag enters (6) by (3), (14), (18), (9), (17), gas (low pressure of mean pressure-regulation) with too high mean pressure, discharge by (28), make the interior pressure of (2) group maintain the low pressure range of regulation.(1) mean pressure in the group air bag comes sufficient than the portion gas that the height of regulation forces down (regulation high pressure-mean pressure) by the gas by (10), (33), (19), (8), (15), (12), (4).Regularly carry out repeatedly, can reach the prevention decubital ulcer and take place.
