Abstract
A ventilating bed cushion includes a frame, a ventilating device, an air supplying device, an upper layer of air-permeable fabric and a lower layer of waterproof fabric. The ventilating device has a polished upper surface and a lower surface. The upper surface is formed with multiple vents. The ventilating device is formed with an inner air guide way for supplying a predetermined amount of air. Therefore, a specific portion of a patient's body lying on the bed cushion can be forcedly ventilated so as to avoid decubitus. In addition, the ventilating bed cushion is widely applicable and can be easily operated. In addition, it has a massaging effect and a low-cost simple structure.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a ventilating bed cushion, and more particularly to a ventilating bed cushion in which the ventilating device is movable to a desired position for forcedly ventilating a specific portion of a patient's body lying on the bed cushion so as to avoid decubitus. The air supplying device can also provide steaming treatment effect and massaging effect. The ventilating bed cushion has wide application range and can be easily operated. In addition, the ventilating bed cushion has simple structure and is manufactured at low cost.
FIG. 1
shows a conventional bed
90
including a hard bed board
91
and a soft bed cushion
92
. with respect to physically defective users, especially those who need to live in a hospital or lie on the bed for a long term, such as a patient, a maimed person or an old-timer, a relative or a guardian must frequently turn the patient's body on the bed. However, in the case of hot weather or poor ventilation or insufficient turning, the patient often suffers decubitus on the back and additionally get hurt.
Therefore, it is necessary to provide an improved bed product which is manufactured at low cost and can be easily operated to avoid the above problem.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a ventilating bed cushion which is able to avoid decubitus and has wide application range and can be easily operated.
It is a further object of the present invention to provide the above ventilating bed cushion which can also provide steaming treatment effect and massaging effect.
It is still a further object of the present invention to provide the above ventilating bed cushion which has simple structure and is manufactured at low cost.
The present invention can be best understood through the following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to
FIGS. 2
to
7
. The ventilating bed cushion of the present invention includes a frame
10
, a ventilating device
20
, an air supplying device
30
, an upper layer of air-permeable fabric
40
and a lower layer of waterproof fabric
50
.
The frame
10
is pivotally connected with a front and a rear rollers
11
,
12
. A front and a rear cranks
111
,
121
respectively outward extend from the front and rear rollers
11
,
12
.
The ventilating device
20
has a polished upper surface and a lower surface with low frictional coefficient. The upper surface is formed with multiple vents
2
l. The ventilating device
20
is formed with an inner air guide way
22
. In addition, the ventilating device
20
is disposed with multiple connecting straps
23
for connecting with the front and rear rollers
11
,
12
.
A switch
31
(or a flow controlling valve) and a connecting tube
32
are disposed between the air supplying device
30
and the ventilating device
20
for supplying a predetermined amount of air to the ventilating device
20
or shutting off the air.
The soft upper air-permeable fabric
40
and the lower waterproof fabric
50
are both fixed on the frame
10
to enclose the ventilating device
20
.
In operation, in the case that a ventilation operation is performed to the back of a user lying on the present invention, an operator can crank (or scroll) the front or the rear crank
11
,
12
. Accordingly, by means of the pulling of the connecting straps
23
, the ventilating device
30
is moved to a desired position for supplying a predetermined amount of air to the surface of a user's body lying on the upper air-permeable fabric
40
.
The present invention has the following functions and advantages:
1. Avoiding decubitus: With respect to physically defective users, such as an old-timer, a patient living in a hospital and a maimed person, a specific portion of the body can be forcedly ventilated so as to avoid decubitus caused by long term of poor ventilation of the skin.
2. Steaming and massaging treatment effect: The air supplying device can provide an air flow at a normal temperature. Moreover, the air supplying device can provide hot wind or steam instead of the air for thermally treating a specific portion of the patient's body such as the waist. Furthermore, the air supplying device can be used in cooperation with specific herbal medicine to achieve a herbal steaming treatment effect. Also, when moving the air supplying device, a massaging effect is achieved for the patient's back.
3. Wide application range: The present invention is applicable to a clinic bed of a hospital, a domestic bed and even a spring bed cushion with sufficient height. The present invention is only rested on the existent bed without changing the structure of the bed.
4. Simple operation: The cranks are manually operable to move the air supplying device. Therefore, a relative or a medical guardian taking care of the patient can easily operate the present invention.
5. Simple structure: The present invention is composed of a frame, a ventilating device, an air supplying device, an upper layer of air-permeable fabric and a lower layer of waterproof fabric so that the components of the present invention are simple.
6. Low manufacturing cost: The present invention is manufactured at low cost so that the patient can easily afford the present invention.
