ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to an air bed structure capable of alternate lying thereon on either of one's sides. And is especially related to an air bed structure of which the aeration functions, except that for lying on one's back, further include single air-bladder aeration on both sides of the air bed, single air-bladder aeration on one side of the air bed, both air-bladder aeration on one side of the air bed, single air-bladder aeration on the other side of the air bed and both air-bladder aeration on the other side of the air bed.
2. Description of the Prior Art
A serious ill patient generally needs lying on a bed for several decades of days, several years or for the whole life long. Lying for years on a bed makes him contact the mattress with his back, buttocks, the skins on these areas will get decubitus by long pressing and bad aeration, and getting rotten skin is the worse. In view of this, the art of medical instrument has had studied and developed air beds which are capable of separate aeration and discharging, in order that time of being pressed of skins may be reduced as much as possible. However, conventional air beds only has too simple function to satisfy the patients' requirement by virtue that an air bed is only divided into several air bladders which are alternately aerated and discharged.
SUMMARY OF THE INVENTION
In view of the non-ideally practical function of the conventional air beds, the inventor studied and develops the present invention to provide an ideal and practical air bed with its novel structure as well as effect for the patients lying long thereon.
The direct object of the present invention is to provide an air bed structure capable of alternate lying thereon on either of one's sides. Wherein, the air bed is divided into four parts, i.e., an upper left side, a lower left side, an upper right side and a lower right side part. In this way, two air valves with unique structural design and with unique piping arrangement as well as electronic control are provided to render the air bladders of the four parts to have various states of aeration and discharging. Thereby, with the present invention, an object of getting the single air-bladder aeration on both sides of the air bed, the single air-bladder aeration on one side of the air bed, both air-bladder aeration on one side of the air bed, the single air-bladder aeration on the other side of the air bed or both air-bladder aeration on the other side of the air bed to make a large turning or a small turning on the bed for lying on either of one's sides can be achieved for a patient.
The present invention will be apparent in its composition of structure and the effect created after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.
