Abstract

PROBLEM TO BE SOLVED: To move and return a person in need of care from/to a bed even by a powerless aged, woman, or child by single hand, by forming a part or 1/2 part of a ring injection nozzle into a different shape from other nozzle hole shapes and forming a part or a 1/2 part of a sheet face injected in tubular shape into a deformed shape, when the sheet is injection-molded. SOLUTION: When a part or 1/2 part of a polymer film injection molding nozzle injection part is deformed, the part only can be continuously formed as a different shape from the other face. If this deformed part is faced to a sheet flat part so as to be a dual structure, it reduces the contact face resistance of the dual sheet. A polymer drawing sheet 3 spread between a person 1 who is in need of care and lying on the side and a bed 2 is folded in two, has a dual structure of the top sheet 4 and the bottom sheet 5, and the surface shape of one of the top and the bottom sides has recessed/projecting shapes. Formation of small recesses/projections and small wave form part on this sheet face in the same way reduces the frictional area to the flat face and can enhance the sliding performance.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet for pulling and moving a lying human body.

[0002]

2. Description of the Related Art A large force is required to move a lying human body such as a bedridden person, but if the sheets laid on the human body are pulled together with the sheets, the human body can be manually shifted.

[0003]

However, this means for pulling out the sheet has the following disadvantages. B) When the lying human body is heavy, since the frictional resistance between the sheet and the bed surface is large, a large tensile stress is required, and a careless caregiver cannot fulfill the purpose. B) When the sheet is pulled with both arms, stress is locally concentrated on the grasped sheet, so that the bed surface may be damaged and a new sheet may be damaged. The present invention has been made to eliminate these disadvantages.

[0004]

SUMMARY OF THE INVENTION The present invention resides in a method for producing a polymer sheet for further reducing the sliding and pulling action of a recumbent human body, and an apparatus and a structure thereof.

As shown in FIG. 1, when a moving stretcher or a moving bed chair device is placed adjacent to a bed and a polymer attracting sheet is pulled from the outside thereof via a rod,
The tensile stress is distributed to the entire seat by the rigidity of the rod, and the human body on the seat can perform the seat transfer operation quietly and safely by the seat sliding action. In this case, even with a single polymer sheet, the desired movement can be performed with less frictional resistance than that of a conventional cotton cloth or other fiber cloth, that is, with a small pulling stress.

In the present invention, as shown in FIGS. 2A and 2B, in a manufacturing process of a double-layered structure or a homogeneous sheet inserted between the upper and lower sheets, a surface such as an uneven shape or a corrugated shape is formed in a part thereof. As a result, the frictional resistance against the flat surface can be further reduced, so that the pulling stress for the movement of the human body is further reduced, and even a weak woman or girl can perform the movement work necessary for welfare and nursing care.

[0007] That is, the same work can be performed when a person in need of lying down who has been conventionally evaded as heavy labor is comfortably removed from the bed, fulfills the necessary care purpose each time, and then returns to the bed again. By doing so, care management can be easily performed.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION If a part or a half of a nozzle ejection portion for injection forming a polymer film (for example, a low-density polyethylene sheet or the like) is deformed as shown in FIG. It can be formed continuously as different shapes. If the sheet flat portion is opposed to the deformed portion to form a double structure, the contact surface resistance between the double sheets is reduced.

In FIG. 1, a polymer attracting sheet (3) developed between a care-requiring person (1) lying down and a bed (2).
Has a double structure of an upper sheet (4) and a lower sheet (5) in two folds. One of the upper and lower surfaces has an uneven surface as shown in an enlarged cross section A in FIG. 2 and has a wavy shape as shown in B.

If a large number of small irregularities and small corrugations are formed on the sheet surface, the frictional area with respect to the flat surface is reduced, and as a result, the slipperiness is improved. Further, if a small wavefront is formed obliquely on the entire surface of the sheet as shown in FIG. 4 by the rolling processing method or the like, the waveforms intersect by using the folded sheet even if the entire surface has the same direction, so that friction can be reduced. Means.

Further, by inserting another sheet having irregularities or a corrugated shape between the flat upper and lower sheets, the frictional resistance between the upper and lower sheets is reduced. In this state, if the upper sheet end (4) is wound one or more turns with a rigid pulling rod, and the rod is pulled, the pulling stress of the rod is transmitted evenly to the entire sheet, and the upper sheet remains on a lying human body. The drawing movement is started in the state of.

In this case, since the sliding action is mainly performed between the upper and lower sheets having less friction, unlike the one-sheet method, the bed surface is not damaged by the pulling action. Further, if the uneven portions are formed on the entire surface of the sheet, the friction between the flat surfaces increases due to the mutual interference of the uneven portions.

[0013]

The low-density polyethylene sheet having good slipperiness is inexpensive, and is formed into a double-folded sheet or a multi-layered sheet, and the slipperiness is further improved by providing small irregularities and corrugations on the surface. The pulling stress caused by the method of pulling the sheet of the reclining human body is greatly reduced, and even a weak elderly person / woman can move or return from the bed of the care-requiring person, which is the basis of nursing care alone. It has tremendous benefits for welfare and nursing care.
