Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mat used for a bed, and more particularly to a mat that can prevent bedsores of a sick person and reduce the burden on a caregiver.

[0002]

[Prior art and problems of the invention]

 Usually, a hospital bed is a pipe frame with a mat laid on it, which allows the upper body to be raised, so the mat should be split in two or folded accordingly. You can do it.

By the way, since bedridden old people cannot personally carry out their own activities, for example, a caregiver must change clothes, defecate, and clean the body.

[0004] In such a nursing work, it is generally necessary to move the patient's body, but in a bed as described above, only the upper body can be raised, and the caregiver must perform the rest, It requires a certain amount of power and is a daunting task for carers of women and the elderly.

In addition, the bedridden old man cannot turn over by himself, which is also a cause of bed sores.

[0006] Therefore, an object of the present invention is to provide a mat that can reduce the burden on the caregiver as described above and prevent bed sickness of the sick person.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the mat of the present invention defines a central substrate by a first boundary line and a second boundary line into a central region and two side regions adjacent to the central region, and at the same time, a first boundary line is formed. A first fold line is provided on the line, and a lower substrate that overlaps the central region and the side region on the second boundary line side is provided on the lower surface of the central substrate via a hinge provided along the first boundary line. The upper substrate is connected to the upper surface of the central substrate, and the upper substrate is overlapped with the central region and the side region on the first boundary line side through a hinge provided along the second boundary line. Forming a composite substrate having a second fold line corresponding to the first boundary line, and a spine overlapping the composite substrate at the center of the composite substrate via a hinge orthogonal to each boundary line. Boards are connected in series, and the first board and the second board are provided on the back board. Corresponding third and fourth fold lines are provided, and an injection port formed by a flexible sheet is provided between the central substrate and the lower substrate, the central substrate and the upper substrate, and the upper substrate and the back plate, respectively. It has an air chamber.

[0008]

[Action]

 In the mat configured as described above, when air is injected into either the air chamber formed between the central substrate and the lower substrate or between the central substrate and the upper substrate, the central region and one side region of the composite substrate are When lifted up at an angle and injecting air into the air chamber formed between the composite substrate and the back plate, the back plate is lifted.

[0009]

【Example】

 Hereinafter, embodiments will be described with reference to the drawings. As shown in FIG. 2, the mat shown in FIG. 1 is composed of a composite substrate 10 including a central substrate 11, a lower substrate 12 and an upper substrate 13, and a back plate 20, and each of the substrates 11, 12, 13 and The back plate 20 has some shape retention.

The central substrate 11 has a rectangular shape, and is divided into a central region and a side region adjacent to the central region by a first boundary line A and a second boundary line B extending in the longitudinal direction, and on the first boundary line A. Is provided with a first fold line 11a.

The lower substrate 12 and the upper substrate 13 are sized to overlap the central region and one side region of the central substrate 11, and each side edge has a same shape as the side region. The plates 12a and 13a are connected in series. A fold line 13b is provided between the upper substrate 13 and the connecting plate 13a.

The lower substrate 12 and the upper substrate 13 are formed by connecting the connecting plates 12a and 13a to the lower surface of one side region and the upper surface of the other side region of the central substrate 11, respectively. The substrate 11 is integrated with the substrate 11 to form the composite substrate 10, and the folding lines 11a and 13b serve as hinge points of the substrates 12 and 13. Further, the upper substrate 13 is provided with a second fold line 13c which overlaps with the central substrate 11 and coincides with the first fold line 11a.

The back plate 20 is overlapped from the vicinity of the central portion in the longitudinal direction of the composite substrate 10 to one end thereof, and the edge on the central portion side of the composite substrate 10 has the second fold line 13c and the fold line. It is connected to the upper surface of the composite substrate 10 via a hinge 21 orthogonal to the line of sight 13b. In addition, the back plate 20 is provided with a third fold line 22 and a fourth fold line 23 which overlap with the second fold line 13c and the fold line 13b while being overlapped with the composite substrate 10.

As described above, in the composite substrate 10 in which the back plate 20 is integrated, as shown in FIGS. 1A and 1B, the central substrate 11 and the lower substrate 12, and the central substrate 11 and the upper substrate 13 are provided. Air chambers 31a, 32a, 33a are formed between the upper substrate 13, its connecting plate 13a, and the back plate 20 by thin synthetic resin sheets 31, 32, 33 fixed to their corresponding peripheral edges. In addition, in each of the air chambers 31a, 32a and 33a, as shown in FIGS. 4 to 6, the composite substrate 10 is provided with air inlet / outlet ports 31b, 32b and 33b.

As shown in FIG. 3, the mat configured as described above has an air pump 40 connected to each of the air supply / exhaust ports 31b, 32b, 33b via a hose 41, and each air is controlled by the controller 42. If the chambers 31a, 32a, 33a can be selectively poured and exhausted, as shown in FIGS. 4 to 6, a part of the composite substrate 10 or the back plate 20 is removed by the injected air. Lifted up, the caregiver can easily wake up the sick person lying on the mat to the left or right or back and forth.

In addition, when a bedridden sick person operates the controller 42 himself and raises his / her body to the left or right or back and forth, the state becomes the same as when he or she rolls over. Can be prevented. In addition, you can wake up at the time you like to look out the window or read a newspaper to change the mood, which also helps prevent old people from becoming blurred.

If only the caregiver performs the injection / exhaust work into each air chamber, it is not necessary to control the electric air pump 40 with the controller 42 as described above, and the foot-operated air pump is used. May be appropriately connected to the inlet / outlet ports 31a, 32a, 33a for use.

Further, the lifting angle of the composite substrate 10 and the back plate 20 is determined by the size of the synthetic resin sheets 31, 32, 33, but it is preferable to set it at about 75 ° at maximum.

[0019]

【effect】

 As described above, in the mat of the present invention, the back plate is attached to the composite substrate including the central substrate, the upper substrate and the lower substrate, and the air gap is provided between the central substrate and the upper substrate, the central substrate and the lower substrate, and the composite substrate and the back plate. A room is provided, and the air chamber is insufflated to raise a part of the composite substrate or the back plate so that the sick person on the mat can be moved to the left or right or back and forth. The care work can be performed easily and the caregiver's burden is reduced.

If the sick person is allowed to inject / exhaust into the air chamber by himself / herself, the sick person who does not turn over can turn into the same state as when he / she rolls over when he / she likes. It is also possible to prevent bed sores and the like caused by not rolling over.

Furthermore, there is an advantage that the joints of the body naturally move by raising and lowering the body forward or backward using this mat, and the contracture of the joints of the bedridden elderly or the like is prevented.
