Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a futon mattress made of urethane mattress or the like with continuous unevenness, which has been practically improved with more concrete and ideal bedding conditions. The present invention relates to a cassette type mattress that also serves as a benefit mattress, which is suitable for a care worker, a nurse, and a person doing laundry.

[0002]

[Prior art]

 Conventional urethane mattresses are molded from a single piece with the same size as the beds known in hospitals, so if the soil, incontinence, or partial damage occurs, the entire mattress must be replaced. In addition, the mattress is used all the time, and the part subject to weight and pressure may deform into a flat shape, and the bed may be inclined depending on the patient's condition. Damage such as shrinkage also occurs. In addition, if it is partially damaged, it cannot be repaired, so it is replaced.If it is dirty, there is a drawback that it takes time and time to wash because it is one piece, so these defects should be eliminated. As a device to avoid, the present applicant has provided a mattress divided into three as of Utility Model Announcement No. 44188 of 1991, and the utilization rate is currently improving.

[Problems to be solved by the device]

 Although it is improving as described in the conventional technology, however, nosocomial infection due to MRSA (methicillin-resistant Staphylococcus aureus) has become widespread in hospitals in recent years, and it has become a serious problem. I am creating a manual. Among these, as measures against illness, disinfection of beds and beds contaminated with germs are required, and therefore mattresses need to be washed and disinfected, and the frequency is very high. Also, labor shortage and shortening of work time are required due to lack of nurses and ward nurses.

However, the urethane mat can be easily washed by dividing it into three parts, but since it has a thickness of about 80 mm, only a few sheets can be put in the washing machine, and the processing capacity is reduced. There were problems such as chipping and time-consuming drying. The present invention has been made in view of such a situation. Frequently contaminated sweat, stains, incontinence, etc. do not easily penetrate into the lower part of the surface. From this fact, a layer with a thickness of about 80 mm is 20 mm in the upper layer part. And a lower layer portion 60 mm apart to form a two-layer stacked structure. By dividing the upper layer that is frequently washed and the lower layer that is good for each dirty washing, the processing capacity of washing is doubled, and the drying time is shortened, the working time is further shortened, and labor is saved. The purpose is to provide the desired clean and comfortable mattress.

[0005]

[Means for solving problems]

 In order to solve the above-mentioned problems, the present invention comprises a cassette cushion which is detachably attached to the upper, middle and lower parts of a cover having a non-slip ridge on the outer surface of the fabric. The cushion is attached using a bag attached to the cover, and the mattress and the mattress are made of urethane foam and the surface uneven structure is almost the same as the mattress. The same size, but with one set of three equally divided pads, or one set of one third and two thirds, was simply stacked to form a two-layer structure. Since it is not stable, a non-slip ridge is attached to the entire bottom surface of the pad ground on the upper surface of the cassette cushion cover, which is the adhesive surface between the upper and lower layers. It can be fixed just by overlapping in this way. At this time, since the cassette cushion in the lower layer is detachably attached to the combination cover, no anti-slip ridge is attached to the bonding surface with the combination cover.

[0006]

[Action]

 The mattress constructed as described above has excellent breathability and moisture permeability due to the inherent properties of urethane foam, but since it has no hygroscopicity, sweat, stains, incontinence, etc., which are frequently soiled, are only on the surface, and the lower part. It does not easily penetrate until. For this reason, a two-layer structure is divided into an upper layer portion that is dirty and a lower layer portion that is less dirty, and the upper layer portion has a thickness of about 20 mm and the lower layer portion of about 60 mm. As a result, dirt such as sweat, stains, and incontinence is processed only by the upper layer. Further, since the one of the present application is as thin as about 20 mm, the number of washing processes can be doubled, and the drying time can be shortened. Or, regular washing is required, but the frequency of washing is extremely low and durability is increased, and since the thickness is reduced to around 60 mm, it is possible to improve processing capacity in a shorter time than before. .

Since the upper and lower adhesive parts have a cushion cover and a non-slip ridge on the side surface of each other, they can be fixed simply by overlapping the upper pad with the lower mattress. Since the work of attaching and detaching to and from the conventional combination cover is omitted, it can be easily replaced. Further, since the pad of the upper layer is divided into three parts, or a combination of one-third and two-thirds, it is possible to replace the dirty or damaged part. The hardness of urethane is also taken into consideration. The upper layer has a hardness of 10.5 Kgf, which is soft to the touch, and the lower layer has a hardness of 27 Kgf to prevent it from deforming into a flat shape by pressing. Therefore, the upper surface is soft and the lower part does not sink, which is ideal for bedding, and the upper and lower layers are separated so that moisture such as sweat that has entered the upper layer is blocked and the lower layer is blocked. There is no such thing as passing to the club.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings. The mattress body A (FIG. 1) of the present invention comprises a combination cover (2), urethane mats (3) (9) and pads (4) (5). The combination cover is made of fireproof fabric and has an anti-slip ridge (6) attached to the outer surface, but it is formed to the size of a generally known bed or duvet. A pair of upper bags (2A), a pair of middle bags (2B), and a pair of lower bags (2C) are provided facing each other on the left and right edges in the longitudinal direction, and are separated by a partition cloth (2D). ing. The bags (2A) (2B) (2C) are structured in a voucher-like structure. Since the cassette cushion (3A) is mounted inside the combination cover (2), the cassette cushion (3A) is formed into a size in which the length of a known ordinary mattress is equally divided into the upper part, the middle part and the lower part. Inside the cassette cushion (3A), surface irregularities are formed by urethane foam.

The pads (4) and (5) have almost the same size as the mattress (1) so that the pads (4) and (5) can be overlaid and integrated with the mattress and further divided into three parts so that they can be partially replaced. It consists of a pad (4), or a pad (4) (5) divided into one-third and two-thirds, and the inside material of the pad is a urethane foam that has surface irregularities formed on it and is covered with a side cloth. Quilting is applied only to the surrounding area, and if the quilting is applied finely, moisture will penetrate more easily than the seams, so only the surrounding area is quilted. Further, in order to fix the pads without slipping when the pads are superposed in a two-layer structure, a non-slip protrusion (6) is attached to the upper surface of the cassette cushion cover in the lower layer. In this case, the non-slip ridge (6) is not attached to the adhesive part (8) to which the combination cover (2) is attached. As a result, the cassette cushion (3) in the lower layer does not interfere with the attachment / detachment to / from the combination cover. Furthermore, by attaching the anti-slip ridges (6) to the entire bottom surface of the pads (4) (4), they can be fixed simply by stacking them. The permeation test was repeated for the thickness of the upper and lower layers, but it was about 20 mm from the upper surface, and since it did not penetrate further, the upper layer had a thickness of about 20 mm and the lower layer had a thickness of about 60 mm. At 80 mm. Since the upper layer is around 20 mm, the drying time is shortened and the surface of the upper and lower urethan foams is uneven so that the breathability and moisture permeability that are necessary for bedding can be improved. In addition to being able to increase the cost, it saves material and reduces the weight.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. I. If it becomes dirty due to dirt or incontinence, it can be easily replaced, and the lower layer can minimize the damage. B. When soiled due to incontinence, etc., only the upper layer is washed, and the lower layer is not soiled, so only the upper layer needs to be washed, and the upper layer is as thin as about 20 mm, so the conventional number of sheets It can be processed several times longer, and the drying time is shortened, and regular washing is required for the lower layer as well, but since it is as thin as 60 mm, it can be processed in a shorter time than before. It is economical because it can treat both detergent and water with 1/4 of the conventional method.

C. When partial replacement is required due to dirt or damage, the upper and lower layers require a non-slip raised fabric to be fixed simply by stacking them on top of each other, allowing easy replacement and attachment / detachment work to / from a conventional combination cover. It is also effective for patients because it can be processed in a short time, and can be laid down in the lower layer temporarily even when there is no sudden replacement or replacement product in stock. D. The hardness of the upper layer is 10.5 Kgf, which is soft, and the hardness of the lower layer is 27 Kgf, so the surface is soft, and the lower layer is hard and does not sink, so that you do not feel tired. In addition, since the upper and lower layers both have a concavo-convex structure, the floor contact area is expanded, body pressure is dispersed, and moisture is pumped by body motion without crushing capillaries. Is diffused and released to the outside, preventing bed sores. E. Even if the bed is inclined, the mattress is stable and stable.
