Description
Technical field
This utility model relates to decubital ulcer prevention and control, particularly a kind of array pressure balance decubital ulcer prevention and control bed.
Background technology
Decubital ulcer is also called pressure ulcer, pressure ulcer (Pressure ulcers; Pu); refer to that body part organizes long-term pressurized; disturbance of blood circulation; histotrophic nutrition lacks; cause skin to lose normal function and the tissue damage that causes and necrosis, be multiplely born in health pressurized and lack fatty tissue protection, without the bone knuckle place that muscular tissue is wrapped up or muscle layer is thinner.Different positions has different predilection sites, dorsal position is apt to occur in occipital tuberosity, scapular region, elbow, sacrococcygeal region, heel, lateral position is apt to occur in outside in auricle, acromion, elbow, hip, knee joint, the interior outside of ankle joint, ventricumbent position is apt to occur in forehead, lower jaw, shoulder, breast, costal margin, crista iliaca, knee joint, toe, and seat is apt to occur in ischial tuberosity.
Decubital ulcer not only can cause local tissue damage, adds the misery of heavy patient, and is developed to downright bad ulcerative stage when it, damage can reach surface of bone deeply, antibacterial very easily enters blood circulation and causes septicemia and jeopardize patients ' lives, and therefore, decubital ulcer is one of reason of Critical Ill Patient and elderly patients' death.Decubital ulcer occurs relevant with numerous risk factor, and the main cause of disease comprises: pressure factor, nutriture, age, humidity of skin etc., even relevant with reaction to psychological stress.The existence of continuous is that decubital ulcer occurs, the key factor of development, and decompression facility plays a key effect in bedsore prevention and treatment.
The air matting that traditional bedsore prevention and treatment mattress mainly comprises cotton-wool mattress, foam mattresses and in recent years goes on the market.
Its resilience of cotton-wool mattress, foam mattresses is all undesirable.Wherein, it is head that people lies on too hard mattress, the back of the body, buttocks, these four points of heel bear pressure, other positions of health are not fulfilled completely, in fact spinal column is in stiff very tense situation, not only do not reach best rest effect, and such mattress of sleeping, the time has been grown and also can damage health; People lies on too soft mattress, and once lying down, whole body depression is gone down, and spinal column is in case of bending for a long time, causes compressing to internal organs, and the time has been grown, uncomfortable, is also unfavorable for health.And due to the defect in service life of cotton-wool mattress, foam mattresses self, resilience in use for some time is significantly declined, the requirement of user comfortable sleeping environment cannot be met, affect the healthy of patient.
Conventional pneumatic mattress also also exists because patient keeps a kind of sleeping posture for a long time, the pressure site that health is contacted with mattress is fixed, therefore easy initiation pressure decubital ulcer, and the part contacted with mattress for a long time due to patient is airtight, thus bring out dermatosis.In addition, this kind of air matting is also without massage treatment effect, and life-time service this kind of mattress, can to the healthy generation certain influence of patient.
For solving above-mentioned Problems existing, Chinese patent 01254920.7, discloses a kind of counteracting bedsores ventilation mattress.By arranging little passage along the patient position that couches on mattress, be connected with the passage on mattress with several ventilation ducts, connect heater to be brushed to make the skin of patient and mattress contact portion, contained the generation of decubital ulcer, be conducive to the healthy of patient.But this patent there is no effect of decompression and massage human body; make the body part couched for a long time effectively to be massaged and to treat, affect the normal function of this body, and patient's position needs timing to rely on artificial conversion; cause nursing intensity too high, further increase nursing cost.
Chinese patent 2010201387396, disclose a kind of massage mattress, provide a kind of mattress comprising electric massager and some elasticity separate cartridge compositions mutually born against, electric massager is provided with in each elasticity separate cartridge, by the vibration of the shuttle belt dynamic elasticity separate cartridge of electric massager, there are certain massage and health-care effect.But, the electric massager quantity provided in this patent is too much, the work efficiency of electric massager is made to be difficult to ensure, very easily there is the out-of-work phenomenon of part electric massager, thus weaken the effect of massage and health care, meanwhile, the electric massager that production quantity is too various can cause mattress production high cost, causes the desire to purchase affecting consumer because mattress price is too high further.
Chinese patent 2008200522317, discloses a kind of massage mattress.Provide a kind of mattress of built-in aerating device, this aerating device is connected by the air sac belt of trachea with mattress outside, is massaged human body by air sac belt.But the air sac belt in this patent needs when massaging manually to take out from mattress, and needing manual inflation, massage object cannot be reached by automatically controlling, and massage functions is limited.
In sum, current domestic existing mattress also exist production cost too high, the drawbacks such as bedsore prevention and treatment and temperature regulate, pressure site is fixing can not be carried out in clinical middle realization to critical patient.
Forefathers have made research and the work of a large amount of pre-counteracting bedsores, but fundamentally could not solve the generation problem of decubital ulcer.Tracing it to its cause is be limited to objective condition, cannot obtain the pressure data of local organization.The basic problem of the generation of decubital ulcer is the long-term pressurized of local organization, does is the pressure that so local organization is subject to how many on earth? the pressure of how just right reduction local? these problems are key points.
Utility model content
For solving the problem of above-mentioned prior art, this utility model provides a kind of array pressure balance decubital ulcer prevention and control bed, can obtain the pressure data of local organization exactly, and make accommodation, reduces local pressure.
The technical solution of the utility model is:
A kind of array pressure balance decubital ulcer prevention and control bed, comprise the mattress above a body and bed body, bed body below described mattress is distributed with the Stress control array be made up of some pressure control units, each pressure control unit is provided with pressure transducer, pressure transducer is by A/D converter connection handling device, and described processor controls the action of corresponding pressure control unit according to the pressure data that pressure transducer gathers.
Concrete, described pressure control unit comprises the worm screw of vertically placing, described worm screw lower end is arranged in the rotating shaft of motor, a universal drive shaft is established at described worm screw top, described universal drive shaft overlaps from top to bottom successively the first clamping plate and the second clamping plate, and be provided with pressure transducer between described second clamping plate and the first clamping plate, universal drive shaft top is circular arc, circular arc top is placed with conformal top board, and described conformal top board is connected by some balancing springs with the second clamping plate.
Preferably, described processor drives the motor action of corresponding pressure control unit by pressure control circuit, and then the lifting of controlled pressure control unit.
