Multiple air passages applied to air mattress

Abstract

A multiple air passages applied to air mattress includes a plurality of transverse bladders, in particular, the bladders are longitudinally compressed to define air passages, and cavities are formed between the air passages and some specific bladders for communicating the air passages with an interior of the aforementioned bladders. The air passages of the present invention can apply to an alternating air mattress or to one with multiple zones. By means of the air passages conducive to an air-crossing transmission and a designated distribution, the present invention preferably omits a complex distribution and attains a neat appearance, lower costs, and a mass production.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a technique of an air transmission for used in air mattresses, in particular to one achieved via a manner without external-connected pipes.[0003]2. Description of the Related Art[0004]Patients who have difficulty in freely ambulating as a result of illness are generally laid on the bed for a long-term time. Whereas, the part where the patient's body, like muscle and skin, keeps in touch with the bed is readily subjected to a poor circulation due to a long-term compression by the weight, with the result that the patient would gently contract a bedsore. The frequency of such symptom occurred to those who have to lie in bed for long time is a nature.

AI Technical Summary

Benefits of technology

[0009]A primary object of the present invention is to provide a multiple air passages applied to air mattress which applies a series of unique air passages in the air mattress. The subject air passages are particularly embedded in the mattress during the producing process. Accordingly, the present invention keeps the subject air mattress from a complicate pipe distribution and adapts to a mass production for economically reducing manufacturing costs. Furthermore, the air mattress without the exposure of the inlet pipes would facilitate a neat appearance and prevent the pipes from dropping off.

[0011]From above, the present invention conduces to a manufacture without pipe distribution, a neat appearance, lower costs, and a mass production.

[0017]Preferably, a supporting portion is permissibly disposed in the air passage to keep the normality in the air circulation and prevent from unexpectedly blocking the cavities.

[0018]Preferably, the air mattress further includes a head bladder able to keep inflating for supporting the human head while lying in bed. Furthermore, the air mattress has a one-way valve disposed in the air passage. The one-way valve serves to avoid the countercurrent of the air after passing and has a supporting portion in appropriate length disposed inside the air passage. The supporting portion assists the air in entering by a single direction. The supporting portion is not arranged at the end of the one-way valve, so that the barometric pressure at the outer end thereof can be blocked by using a blocking unit to automatically shut the air passage off.

Problems solved by technology

Whereas, the part where the patient's body, like muscle and skin, keeps in touch with the bed is readily subjected to a poor circulation due to a long-term compression by the weight, with the result that the patient would gently contract a bedsore.

In connection with patient having the bedsore, he or she inevitably becomes uncomfortable in view of the fester and sore impinging on the skin and even suffers from the possibility of septicemia and amputation.

Accordingly, a precaution against the bedsore is a sorely significant issue for the long-term patient in bed.

The aforementioned air mattress in such pipe-distributed manner may however have shortcomings as described below:1. The pipe externally mounted at the side of the air mattress would result of a complex pipe distribution while in production, consume lots of working time and labors, and increase manufacturing costs.2. The exposure of the pipes to the air mattress substantially gets a bad appearance and may drop the joint of the pipes off when users incautiously stumble on the pipes, which adversely affects the operation of the air mattress.
