Description

[Detailed description of the invention] This invention is aimed at being used in hospitals for patients who have been confined to their beds for a long time. The present invention also relates to a method for producing a healthy pine tress.

These patients suffer from pressure sores caused by the flat surface of the pine tress. It is normal to be discouraged. This flat pine tress makes the pine tress waterproof. Thin protection made of flat plastic material for ease of cleaning protected by a cover. This thin waterproof protective cover is suitable for use with flat mats. This increases the disadvantages of pressure stress and promotes pressure sores in patients. Today hospitals and the elderly Pine tresses are used in nursing, but it does not bother the bed for a long time. It is directed towards the patient. However, such pine tresses are It is extremely complex and expensive. Therefore, it is not commonly used as much as desired. The current situation is that there is no one. As a result, many patients today prefer to sit on flat, hard materials. Because he has to sleep in bed, he quickly develops bedsores.

Certain of such pine tresses are e.g. disclosed in US-A-328791. However, the healthy pine tress shown there contains one or several layers. The entire upper surface of the pine tress is formed by a body or core and a layer having a porous shape. It consists of a covering surface layer, and the side surface of that layer opposite to the core in cross section is the so-called It has an uneven surface in the shape of a loose egg-shaped flying structure, that is, the uneven shape is One convex part is surrounded by 41 concave parts on all sides, and four convex parts are surrounded by the saddle surface. connected to each other by the saddle surface in such a way that the parts are connected to each other. The surface of the layer on the 8th side has a flat surface. Ru.

The main purpose of the present invention is to manufacture a healthy pine mattress that does not cause bedsores. That is. And if bedsores occur due to traditional pinerests, It is easy to treat, easy to clean, and inexpensive to manufacture. It is an attempt to provide a waterproof pine tress.

Other objectives are that porous plastics have waterproof properties and that the surface of porous plastics The surface has a cell system that is generally 100% sealed, and the surface is waterproof; This is achieved by a healthy pine tress that is smooth, and in this way the pine The tress is the lowest point of the saddle located vertically between the hole and the adjacent convexity. A cushion is formed between. It is also an object of the present invention to provide a closed cell system. one or several relatively thin layers of similar plastics are bonded or A layer of polyurethane foam is applied to the plastic core, and its core may be constructed of urethane foam, metal coils or similar materials. stomach. Porous plastics are heat treated with heated air to achieve 100% cell sealing. It may be processed and constructed, and then cut to an appropriate size. Another process is , a relatively thin layer of porous plastic is heat treated and cut to an appropriate size. by applying it to traditional pine tresses, such as spring-type pine tresses. be.

Useful developments or embodiments of the healthy pine tress of this invention are defined in claims 2 to 8. have defined characteristics.

The invention has many advantages. It is easy to process and has reasonable manufacturing cost. provides a comfortable surface for patients, is easy for hospital staff to clean, and is Cleaning agents or disinfectants containing alcohol can be easily used and at the same time the weight It has the advantage of being lightweight. Healthy pine tress of different weight or size Another advantage is that it is relatively easy to manufacture.

The surface structure of the invention provides an air cushion for resting the body at the lowest point of the pinerest. and a saddle-like surface and is therefore extremely important for patients with pressure sores. It's convenient. As the tip massages the surface of the body, blood circulation is promoted and the floor The treatment of the deviation becomes easier and its progression is stopped.

Even if the patient is incontinent, the urine will be collected in the hole and the patient will not get wet. Does not require the use of diapers. Pine tress can be washed clean with water, Ready for immediate use. For example, hospital staff have to pick up and drop off patients. Or maybe your body gets tired from tossing and turning, and if you rest on a pine mattress, it will hurt your back. It can give you some rest. This is due to the pine surge effect of pine tress. be.

The pinerest of the present invention is also suitable for patients who have been injured by burns or the like. That is, six This is because air of different temperatures circulates inside the pine tress, and this pine tress reduces the contact surface of the body and relieves the pressure of pine stress in an advantageous way throughout the body. This is because it disperses and minimizes the generation of humidity and heat between the body and the bed.

The healthy pine tree of the present invention can have twice the lifespan of conventional healthy pine trees. It has been proven. This pine tress can be used with a plastic cover or pine tress cover. do not need. Requires repair or maintenance of equipment, motors, etc. that make disturbing and loud noises No complicated accessories are used.

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.

Figure 3 shows a pine tress that has a surface layer that does not completely cover it and a core that consists of several layers. The figure shows the pine tress viewed from the side.

Figure 4 shows examples of different hump shapes seen in perspective views. , the surface layer may be one or more layers, such as polyethylene foam plastic. A cell structure that completely surrounds the core or main body and is 100% sealed. It is made of porous polystyrene plastic with an uneven surface.

The core of this pine tress is 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 layer is formed by abutting the uneven surfaces facing each other so that the tips are facing each other. A hard sheet is placed between the eyebrows, but the core is a traditional pine tress. Good too.

Figure 3 shows that the surface layer of porous polyethylene plastic has an uneven core. Alternatively, the present invention is shown in which a part of the main body 2 is simply covered. This body 2 has several layers. That is, the uneven sheet 3 made of polyethylene cellular plastic or polyethylene Even if it is composed of a plastic sheet 4 and a concave-convex sheet 5 of polyurethane foam plastic, good.

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

Figure 5 shows a textured porous polyethylene plastic with a closed cell system. 2. How is the diaphragm formed around the core 2, cut and glued to the core and heat treated? It is shown how well the tubes are processed to form a 100% seal.

This shape is a block or mass of porous polyethylene plastic. is transferred between shaping rollers 7.8, thereby forming a porous polyethylene plastic. Obtained by compressing plastic into a zigzag pattern under great pressure.

The compressed porous polyethylene plastic is cut approximately half its height by knife 9. Cut horizontally into minutes to form a permanent egg carton-like shape on one side and the other On the side 11, a plane cut surface is formed.

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

When this process is completed, the flat side of this layer is exposed to the adhesive roller 12, which applies the adhesive. It is moved up and its surface is attached to the core of the pine tress. And only a little A certain amount of pressure is applied to obtain good contact and the surface is bonded 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.

A block of porous polyethylene plastic is passed between two shaping rollers, The advantage is that it applies greater pressure and forms a zigzag pattern. Within the scope of the present invention. Compressed porous polyethylene plastic makes it is cut horizontally by knife 9 to approximately half its height, resulting in a permanent egg. A carton-like shape of is formed on one side, i.e. one protrusion is at right angles to each other. It is surrounded by four concave parts in the direction and connected to four convex parts through the saddle surface. In this way, the convex portion and the concave portion are connected to each other. Porous polyethylene viewed from the side A relatively thin layer of plastic will conform to the core where it will be coated with the layer after heat treatment. Cut to appropriate length to fit. Porous polyethylene plastic viewed from the side A relatively thin layer is then applied around the core to ensure easy mounting. Unify with something like black tape. The core looks like a spring pine tress type. A conventional pine tress may also be used. Alternatively, chairs, sofas, wheelchairs, cars or buses. A pine tress used as a school chair may also be used. By changing the height of the sides , pine tresses adapted to different weights can be manufactured. If the distance between the tip and the valley is large The larger the pine tress, the more weight the person using it will be able to carry. Furthermore, the top The horizontal distance between them may be varied according to the weight and size of the user. desired weight For a suitable pine tress, the plastic layer 1 on the side can be colored in different colors. It can be easily obtained by For example, blue colored plastic weighs 75-85 kg, Red is 65-75kg, green is 55-65kg, yellow is 45-55kg, etc. It is. In this way, the storage and operation of pine tresses can be carried out in consumer stores, This will be easier in hospitals and facilities for geriatric care.

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

The results are as follows.

1. Born in 1917, weighing 46 kg, suffered from incontinence and was confined to a wheelchair and bed. The woman, who had been spending the night at the bar from 7 p.m. to 9 a.m., was killed by a pine tree in August 1988. At first, it was painful, but now there is no pain.

2. Born in 1910, weighing 36.9 kg, he was very thin and lost his life sitting in an easy chair. The woman, who was suffering from a withdrawal syndrome, slept from 2:20 p.m. to 9:30 p.m. On August 17, 1988, she was given a pine tress, and at first she had bedsores and turned over in bed. However, with this new pine tress, the bedsores disappeared within a few days, and after 2 months, the bedsores disappeared. The pain disappeared.

3. Born in 1908, weighing 35 kg, confined to a wheelchair and in bed from 7 p.m. The woman who stayed there until 9 a.m. was hospitalized from September 30, 1988 to November 1988. Pine stress was given to her for 20 days, and she was recovering at home, but at first she felt pain. However, the pain disappeared during his stay in the hospital.

4. Born in 1922, weighing 62.5 kg, he was incontinent while sitting in an easy chair. and had diarrhea, and slept in bed from 2:30 p.m. to 10:00 p.m. The man was given a pine tress on October 13, 1988. dimple in the back There was some pain, but the pain disappeared on October 14, 1988.

5. Born in 1903, weighs 54 kg, sits in an easy chair, and is in bed at 6 p.m. The woman who was there from 9:30 to 9:30 had a red butt and back, but After being given a response, it improved and is now pain-free.
