ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to an air bed structure capable of alternate aerating and lying thereon on one's side. And especially to an air bed structure of which the aeration function can include the multiple styles such as complete aeration, first one-side aeration, second one-side aeration, first alternate aeration, second alternate aeration etc.
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 and 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 divided only 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 aerating and lying thereon on one's side. Wherein, the air bed is divided into a right and a left side part (which each includes several air bladders) except an elongate air bladder used as a protection cushion or a bottom cushion. Air bladders of each part are divided into several sets which are alternately arranged relative to each other. Air bladders of each set are communicated with one another. 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 air bed to have the novel function of complete aeration, first alternate aeration, second alternate aeration, and especially, first one-side aeration and second one-side aeration etc. Thereby, with the present invention, an object of lying on the air bed on one's side can be achieved.
Following the above stated direct object, the present invention can have the indirect objects as stated below:
1. As for a patient or an old person lying on the air bed for a long period, the function of lying on the air bed on one's side (right side or left side) can get rid of dullness and boringness induced when he can only lie on his back to see the ceiling, and can enlarge his field of view to make more pleasure as to his emotion psychologically.
2. As for a patient with drowned lungs, by virtue that the present invention allows lying on the air bed on one's side, water in the lungs can be made shaking timely to lower propagation rate of germs and thus to avoid rapid propagation of germs due to unmoving for a long time (this is like the way that mosquitoes propagate in a vessel with water).
3. As for a patient being subjected to getting phlegm and pus in his respiratory organ, by virtue that the present invention allows lying on the air bed on one's side, rate of suffocation by over amount of phlegm and pus can be lowered.
4. As for a patient being in need of changing dressing of a wound or in need of patting his back, a nurse can change dressing of the wound or pat his back easily after lying on one side of the patient on the bed. This can reduce inconvenience and suffering of body weight.
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.
