Sand levitation beds are worth more than half a million dollars each, while air-pulsed levitation beds are nearly a million dollars.
Sand suspension bed filled with 600 kilograms of silicon and ceramic synthesis of fine sand. Each grain of sand is only 50-150 microns in diameter, so fine that it is invisible to the naked eye. The sand acts as an intermediary between the bed surface and the body, forming waves through the airflow and "levitating" the person lying on it.
Air pulsation levitation bed is controlled by precision circuitry and a variety of sensors, so that the air in the airbag up and down pulsation, so that the patient lying on it "levitation" up. There are also a variety of positional adjustments that make it easy for patients to receive a variety of treatments, and it avoids the risk of sand silicosis and the cost of replacing sand particles.
The two types of beds also have drying functions, which can dry the wound exudate in time to avoid infection and bedsores. The application of suspension beds greatly relieves the pain of burn patients and also shortens the healing time of wounds greatly.
Expanded Information
Operating Principle:
Suspension bed is designed to utilize the principle of gas flow levitation, through the pressurized air to the silica sand, so that the silica sand into a fluid, the formation of buoyant force in the movement, and effectively prevent the wound from being pressurized, and at the same time, dry and hot air through the silica sand and the filter sheet blown to the wound to form a dry and hot air, continuously around the wound. At the same time, the dry hot air is blown to the wound through the silica sand and filter sheet, forming dry hot air, continuously surrounding the patient's body surface, which is favorable for warmth and wound dry scab.
Two, role:
(1)? Reduce wound exudation, dry scab fast. Suspended bed because of its own air-heat function, temperature control and dehumidification so that the moisture of the wound can be distributed in a timely manner, through the continuous action of dry and hot air, the scab is fast.
(2)? Avoid pressure on the wound. Under the buoyancy formed by the movement of silica sand, the body is in the state of floating, suspended bed so that the wound in the soft silica sand buoyancy to avoid pressure, does not affect the local blood circulation, so that the epithelial cells can grow in a suitable environment.
(3)? The use of suspension beds without turning over, improve the comfort of patients and the safety of treatment, reduce the pain of turning over and the difficulty of changing medication, so that the operation of medical, nursing, life and other operations are convenient, saving manpower and material resources.
(4) The in-bed sand flow provides a dry and relatively alkaline environment for the wound, which is not conducive to bacterial growth and reduces the chance of infection in the skin donor area.
(5) Suspension bed treatment can also increase the survival rate of skin fragments after skin grafting surgery.
