Description The present invention relates to a health mattress intended for use in hospitals for patients who have been suffering from bed problems for a long time, and also to a method for manufacturing the same.

Such patients commonly suffer from pressure sores caused by the flat surface of the pinerest. Such flat pine tresses are protected by a thin protective cover made of flat plastic material to make the pine tress waterproof and convenient for cleaning. This thin, waterproof protective cover magnifies the disadvantages of flat mattresses and promotes pressure sores on the patient. Today, pine mattresses are used in hospitals and geriatric patients, but they are intended for patients who have been suffering from bed rest for a long time. However, such pine tresses are complex and expensive to manufacture. Therefore, at present it is not commonly used as much as desired. As a result, many patients today quickly develop pressure sores because they must sleep on flat, hard surfaces.

Certain of such pine tresses are disclosed, for example, in US-A-328791, in which the healthy pine tresses shown have a body or core comprising one or several layers and a porous form. The surface layer covers the entire upper surface of the pine tress formed by the layer, and the side surface of the layer opposite to the core in cross section has an uneven surface in the form of a so-called egg-shaped knob structure, In other words, the uneven shape is such that one protrusion is surrounded by four recesses on all sides, and the four protrusions are connected to each other by the saddle surface. The connected layer has a convex portion and a concave portion, and the core side surface of the layer has a flat surface.

The main object of the present invention is to manufacture a healthy mattress that does not cause bedsores. Furthermore, the present invention aims to provide a waterproof pinerest that is easy to treat even if bedsores occur due to conventional pinerests, is easy to clean, and can be manufactured at low cost.

Another purpose is that porous plastics have waterproof properties and that the surface of porous plastics is generally 100% waterproof.
This is achieved by a healthy pine tress that has a cell system that seals % and whose surface is waterproof and smooth; in this way the pine tress has the lowest point, holes and holes when viewed vertically. A cushion is formed between saddles located between adjacent projections. It is also an object of the invention that a relatively thin layer of a similar plastic with a closed cell system is applied by adhesive or other method to a polyurethane foam plastic core consisting of one or several layers, the core being is urethane foam,
It may also be constructed from a metal coil or something similar. Porous plastic is 100% cellular
It may be constructed by heat-treating it with heated air in order to obtain airtightness, and then cutting it into an appropriate size.
Another process is to heat treat a relatively thin layer of porous plastic, cut it to size, and apply it to a conventional pine tress, such as a spring type pine tress.

Useful developments or embodiments of the healthy mattress according to the invention have the features defined in claims 2 to 8.

The invention has many advantages. It is easy to process, provides a comfortable surface for patients at a reasonable manufacturing cost, is easy for hospital staff to clean, and can easily be used with cleaning agents or disinfectants containing alcohol. It also has the advantage of being light in weight. Another advantage is that it is relatively easy to produce healthy pine tresses of different weights or sizes.

Due to the surface structure of the invention, an air cushion for resting the body is created between the lowest point of the pinerest and the saddle-like surface, which is therefore very convenient for patients with pressure sores. Since the tip massages the surface of the body, blood circulation is promoted, facilitating the healing of pressure sores and preventing their progression.

Even if the patient is incontinent, the urine will be collected in the holes in the pine tress, and the patient will not get wet and will not need to use a diaper. Pine tresses can be flushed clean and can be used immediately. For example, when hospital staff rest on a pine mattress, their backs can be given considerable rest when their bodies are strained to lift, lower, or turn patients. This is due to the pine surge effect of pine tress.

The pinerest of the present invention is also suitable for patients who have been injured by burns or the like. This is because air of different temperatures circulates in the holes, and this pine tress reduces the contact surface of the body with the bed, distributing the pressure of the pine tress in an advantageous way over the whole body, This is because it minimizes the generation of humidity and heat between the body and the bed.

The healthy pine tress of the present invention has been proven to have twice the lifespan of conventional healthy pine tresses. This pine tress does not require a plastic cover or pine tress cover. There are no disturbing or noisy devices or complex accessories such as motors that require repair or maintenance.

The invention will be explained in more detail by way of example in the accompanying drawings, in which: FIG.

FIG. 1 is a cross-sectional view of a healthy pine tress showing the surrounding layers and core sectioned.

FIG. 2 is a sectional view of the healthy pine tress viewed from the side.

FIG. 3 shows a side view of a pine tress having a surface layer that does not completely cover the pine tress and a core consisting of several layers.

FIG. 4 shows examples of different tufted shapes seen in perspective view.

FIG. 5 shows the processing steps of the present invention.

1 and 2, the surface layer completely surrounds a core or body consisting of one or more layers, such as polyethylene foam plastic.
It is made of porous polystyrene plastic with irregularities and a cell structure that is 100% sealed.

The core of the pine tress consists of a uniform layer of polyurethane cellular plastic or two or more layers with an uneven surface on one side and a flat surface on the other, the layers abutting the uneven surfaces facing each other. The core may be a conventional pine tress, although a rigid sheet is placed between these layers.

FIG. 3 shows the invention in which a textured, porous polyethylene plastic surface layer merely covers part of the core or body 2. FIG. The body 2 may consist of several layers, namely a textured sheet 3 of polyethylene cellular plastic, or a polyethylene sheet 4 and a textured sheet 5 of polyurethane cellular plastic.

FIG. 4 shows different shapes of nubs suitable for use in the present invention.

Figure 5 shows how a textured porous polyethylene plastic with a closed cell system is formed around the core 2, cut and bonded to the core and heat treated to form a 100% hermetic seal. It is shown.

Such a shape is obtained by transferring a block or mass of polyethylene porous plastic between shaping rollers 7, 8, thereby compressing the polyethylene porous plastic into a zigzag pattern under high pressure.

The compressed porous polyethylene plastic is cut horizontally to approximately half its height by a knife 9, forming a permanent egg carton-like shape on one side and a flat cut on the other side 11. A surface is formed.

The thickness of porous polyethylene plastic,
By changing the pressure of the roller, layers with different shapes and thicknesses with different heights of unevenness are formed.

When this step is complete, the flat side of this layer is
is moved onto an adhesive roller 12 that applies adhesive;
Its surface is attached to the core of the pine tress.
Then a slight pressure is applied to get good contact and the surface is glued to the core.

Heat treatment with heated air 14 is performed to seal the cell 100%.

The core with the glued waterproof layer is then cut to size.

It is within the scope of the present invention to advantageously pass a piece of porous polyethylene plastic between two shaping rollers, thereby applying a large amount of pressure to form a zigzag pattern. The compressed porous polyethylene plastic is then cut horizontally to approximately half its height by knife 9, so that a permanent egg carton-like shape is formed on one side, i.e. The convex portion is surrounded by four concave portions that are perpendicular to each other, and the convex portion and the concave portion are connected to each other so as to be connected to the four convex portions via the saddle surface. A relatively thin layer of porous polyethylene plastic viewed from the side is cut to an appropriate length to fit the core which will be coated with the layer after heat treatment. A relatively thin layer of porous polyethylene plastic, viewed from the side, is then applied around the core and held together with something like Velcro tape for easy mounting. The core may be a conventional pine tress, such as a spring pine tress type. Alternatively, it may be a pine tress used as a chair, sofa, wheelchair, bicycle or bus chair. By changing the height of the sides, pine tresses adapted to different weights can be manufactured. The greater the distance between the tip and the valley, the more weight the person using the pine tress will need to carry. Furthermore, the horizontal distance between the tops may vary according to the weight and size of the user. A mattress suitable for the desired weight can easily be obtained by coloring the side plastic layer 1 in different colors. For example, blue colored plastic weighs 75-85 kg, red plastic weighs 65-75 kg, and green plastic weighs 55 kg.
65Kg, yellow is like 45-55Kg. In this manner, the storage and operation of the pine mattress is facilitated in consumer stores and facilities such as geriatric hospitals.

The pine tress according to the invention was tested in the fall of 1988 in a ward for senile dementia patients.

The results are as follows.

1. A woman who was born in 1917, weighed 46 kg, suffered from incontinence and was confined to a wheelchair in bed from 7:00 pm to 9:00 am. In August 1988, she was given a pinerest, which at first caused severe pain. However, there is no pain now.

2. Born in 1910, weighing 36.9 kg, he was extremely thin, suffered from incontinence while sitting in an easy chair, and was 14 years old.
On August 17, 1988, the woman, who had been sleeping from 1:20 to 9:30, was given a pine tress, and at first she had bedsores and was tossing and turning, but with this new pine sling, the bedsores disappeared within a few days. However, the pain disappeared after 2 months.

3. The woman, born in 1908 and weighing 35 kg, was confined to a wheelchair and spent her time in bed from 7pm to 9am.
The patient was given a pine tress for the 20th day of the month, and was subsequently treated at home. Initially, the patient was in pain, but the pain disappeared during his stay at the hospital.

4. Born in 1922, weighing 62.5 kg, sitting in an easy chair, incontinent, and occasionally suffering from diarrhea.
The man who slept in bed from 14:30 to 10:00 was given a pine tress on October 13, 1988. There was some pain in the pit of my back, but by October 14, 1988, the pain had disappeared.

5. A woman born in 1903, weighing 54 kg, sitting in an easy chair, and spending time in bed from 6:30 pm to 9:30 pm, had redness on her buttocks and back, but when she was given a pine tress, her condition improved and she is now is free from pain.
