Design and development of air ventilated air bed for hospitalized patients

Abstract

Proper ventilation is a critical consideration for the comfort of hospitalized patients. Dry skin, skin rashes, weariness, poor sleep, and other concerns caused by insufficient ventilation can all be avoided with proper ventilation. Air-Ventilated Air Beds are used to supply air to the major parts of the patient’s body. This air bed is constructed in such a way that air is circulated con-tinually throughout the body of the hospitalized patient. It is especially beneficial for people who are bedridden and need to spend a significant amount of time in bed due to illness. Exces-sive heat generated between the bed and the patient is perhaps the common cause of bedsores. Sweating is the leading cause of bedsores. Air ventilation is included in the system to prevent sweating and reduce the incidences of bedsores. Dual compressors, rubber tubes, flow control valves, and anti-decubitus mattresses are among the components used. The rubber tubes are used to ventilate the space between the body of the patient and the upper surface of the air bed. Above the mattress, the rubber tube mesh is positioned. The air is first compressed in two compressors before passing through the distribution manifold and through the meshing. The tubes are altered by drilling holes at certain intervals. The air from the compressor is circulated through the pipes before passing through the openings in the pipes. The unrestricted passage of compressed air via a capillary tube lowers the temperature of the air. The air exhausted through the capillary tubes maintains the patient’s body temperature stable for a while before lowering it. The air is ventilated throughout the bed in this manner. Bedsore can be avoided by reduction of sweat by using the air in close contact with the patient.
