Description

Full-automatic pressure sore prevention nursing bed and using method thereof

Technical Field

The invention relates to the technical field of nursing beds, in particular to a full-automatic pressure sore prevention nursing bed and a using method thereof.

Background

Pressure sores (commonly known as bedsores) are limited injuries of skin or potential subcutaneous soft tissues, the incidence rate of hospitalized patients in general hospitals is 3% -14%, the incidence rate of treatment in home without hospitalization is 50%, the pressure sores are caused, not only are physical and mental pains caused, but also the family burden of patients is increased due to the increase of treatment cost and nursing amount, even the pressure sores which are not cured for a long time are easy to cause skin cancer, osteomyelitis, septicemia, hypoproteinemia and the like, the life of the patients is threatened, and the death rate is increased.

The formation of pressure sores is a complex process, and the pressure sores are considered to be the result of the combined action of vertical pressure, friction force and shearing force and various internal and external factors of an organism at present, wherein the vertical pressure is the most common reason for the formation of the pressure sores, and the blood flow is unsmooth when the skin is pressed for a long time, so that ischemia, oxygen deficiency and nutrient substance deficiency are caused to damage the skin; the friction force is not a leading factor causing ischemia, but acts on epithelial tissues, removes the protective keratinized skin on the outer layer, increases the sensitivity of the skin to pressure sores, causes the separation between cells on the upper layer of the epidermis and cells on the basal layer of the epidermis, causes hyperemia, edema, hemorrhage, inflammatory cell aggregation and dermal necrosis, simultaneously, because the barrier function of the skin is damaged, the oxygen and nutrition supply of the epidermis is insufficient, pathogenic microorganisms are easy to invade, the tissues are easy to be pressed and injured, in addition, the friction force can increase the local temperature, the occurrence of metabolic disorders and the final formation of pressure sores are facilitated, and the dragging action when a patient is carried, sheet folds or scraps are common clinical friction sources; the shearing force is a mechanical force which is generated in deep tissues and causes the soft tissues to deform in the transverse direction, when the body is fixed, the body tilts due to the action of gravity, a deep fascia and a bone tend to slide downwards, the friction force of a chair or a bed sheet keeps the skin and a shallow tendon in place, so the shearing force is generated and is a reaction of the friction force, the shearing force can obviously increase the harm of vertical pressure, blood flow blockage occurs under lower pressure due to the fact that blood vessels among the tissues are stretched, twisted and torn, the blood supply of a larger area is cut off, the oxygen tension of the tissues is reduced, and deep necrosis is caused.

Although a nursing bed in the current market can independently turn over and sit a patient, the workload of family members and nursing personnel is greatly reduced, for an old person lying in bed for a long time, when the old person eats a meal, the bed head of the nursing bed is lifted to help the old person to sit up, the skin of the sacral tail of the old person stays in place under the action of the bed sheet friction force, and the bone slides downwards under the action of gravity, so that shear force is generated at the sacral tail. Therefore, a full-automatic pressure sore prevention nursing bed and a using method thereof are provided.
