JPH05146470A - Decubitus preventive mat - Google Patents

Abstract

PURPOSE:To prevent the generation of a decubitus by connecting the space parts of respective mats constituted by bonding the peripheral edges of soft sheets and forming the parts enclosed with the peripheral edges on the inner and outer sides of endless curvilinear lines by line adhesion to a liquid forcing pump via a rotary valve. CONSTITUTION:The mat bodies A to E are formed into hemming parts 2 by previously bonding the peripheral edges of two sheets of upper and lower soft sheets and are connected to each other by line adhesion of the inside surfaces of the upper and lower sheets enclosed with the hemming parts 2 in the form of the endless curvilinear lines to form the spaces (a) enclosed by the endless curvilinear lines and the spaces (b) sandwiched by the outer side of the endless curvilinear lines and the inner side of the hemming parts 2; thereafter, fluid inlet/outlet pipes 3a, 3b communicating with the spaces (a), (b) are installed to the mat bodies. These mats A to E are constituted by integrally connecting all of the respective fluid inlet/outlet pipes 3a, 3b to a rotary valve 5 so that the spaces (a), (b) are alternately bulged at specified periods by the fluid, such as compressed air or warm water, sent from the pump P.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat for preventing ulcers, which are so-called bed sores, which occur in the body of a patient who is long ill and debilitated.

[0002]

BACKGROUND OF THE INVENTION [0002] Acne is a kind of gangrene that occurs in a weakened body that is susceptible to pressure, so in order to prevent it, the supine state of the sick person is changed from time to time. It is necessary to change the compression position by moving the patient, but forcibly moving the debilitated sick person may warp and worsen the illness, and it is not easy to lift the sick person with few caregivers. In the current situation, a thin mat made especially soft is laid and the sick person is laid on it.

[0003]

On the other hand, according to the present invention, the mat itself is preliminarily formed with a wide raised portion on its surface, and the raised portion supports the body of a sick person, and the contour of the raised portion is By adopting a structure that changes from time to time, it is possible to appropriately change the compression position for the sick person caused by the continuation of the supine state without moving the sick person.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a plurality of mats mainly supporting the space between the head and the feet of a supine patient (the embodiment shown in the drawings). 5) in A), B, C, D, and E. Of these, the main mat C for supporting the hips, which is the center
It is preferable that a circular hole 1 for defecation is previously provided in the center of the hollow body.

As shown in FIG. 2, these mat main bodies A to E form upper and lower sheets of a portion surrounded by the edging portion 2 while forming the edging portion 2 by preliminarily bonding the upper and lower soft sheets together at their peripheral edges. The inner surfaces are connected to each other by wire-bonding them in the shape of an endless bending line to form a space a surrounded by the endless bending line and a space b sandwiched between the outside of the endless bending line and the inside of the edging portion 2. After that, fluid inlet / outlet pipes 3a, 3b communicating with these spaces a, b are additionally provided.

Numerals 4 ... are eyelet holes transparently provided in the edging portion, through which the mats are arranged and fixed on a desired bed or mattress.

As described above, each of the mats A to E is formed by partitioning and forming a space a and a space b inside the hollow body. Of these, when the circular hole 1 is previously provided in the central portion of the mat C for the hip portion, a part of the space a is formed in a notched circular shape surrounding the circular hole 1 as apparent from FIG. There is.

As shown in FIG. 1, the mat main bodies A to E are connected to a well-known rotary valve 5 together with the respective fluid inlet / outlet pipes 3a ... 3b. Spaces a and b are alternately bulged at regular intervals by a fluid such as air or hot water.
Reference numeral 6 is a pressure responsive switch provided on the pump P.

FIG. 4 shows an operation sequence of the rotary valve 5 described above. That is, in FIG. 4 (a), the fluid from the pump P flows into the spaces a ... through the spool 7, and at the same time, the fluid in the spaces b ... Is discharged from the discharge holes 8 to the outside. , The spaces a ... swell and the spaces b ... contract.

Next, when the spool 7 is slightly rotated counterclockwise as shown in FIG. 2B, the fluid from the pump P flows through the through hole of the spool 7 into the space b ...・
.. The fluid inside is discharged from the discharge hole 8 through the through hole of the spool 7, thus expanding the space b.
・ ・ Shrinks.

The rotation of the spool 7 is performed in advance by a timer, for example, every 5 minutes, and the fluid pressure is such that the pump P is driven at a constant pressure via the pressure response switch 6 at all times. As a result, each mat main body A to E
On the surface of the, the spaces a and b are alternately bulged and contracted repeatedly, so that the pressing position for the sick person is appropriately changed.

[0012]

The present invention can be used by mounting it on an ordinary sick person bed or an easy chair type bed surface with the above-mentioned constitution, but the surfaces of the mat main bodies A to E are partially alternated. As described above, it is possible to prevent the occurrence of acne as described above. In addition, when the circular hole 1 is provided in the center of the mat main body C for supporting the buttocks in advance, it is equipped with a toilet bowl. A bed, that is, a bed for which a defecation hole is provided on the surface of the bed and the toilet bowl is hung on the lower surface of the bed, the circular hole 1 can be adapted to the defecation hole and used at any time, It is extremely efficient.
