Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an air mat for a bed, and particularly to an air mat for a bed installed on a bed in a hospital or the like.

(Prior art and its problems) In hospitals, it is common practice to transport patients who are unable to walk from their rooms to operating rooms or examination rooms for treatment, examinations, etc. Depending on the condition of the patient and the injury, it is preferable to transport the patient in a stable condition without touching the patient's body as much as possible.To do this, a patient transport vehicle is placed next to the longitudinal side of the bed, and the patient is placed on the bed. The most preferable method of transportation is to transport the patient in parallel to the patient transport vehicle.

By the way, depending on the patient, it may be necessary to use an air mat as a bed sheet to avoid local pressure, but air mats are usually made of rubberized cloth or leather and have poor lubricity, so they cannot be used as described above. When transferring a patient, it is difficult to move the mat smoothly in parallel from the bed to the transfer vehicle.

In addition, some conventional air mats for sleeping beds have a plurality of cylindrical bags arranged in parallel so as to be perpendicular to the longitudinal direction, as described in Japanese Utility Model Application Publication No. 61-51814. Although the air mat was sufficient in terms of smoothness in the direction of parallel movement to the patient transport vehicle attached next to the longitudinal side of the bed, it did not take into account parallel movement as there was no part to hold the hand during tensioning. Moreover, simply providing a handle on the side of the air mat may also cause new problems.

In other words, the end faces of the cylindrical bags are lined up on the longitudinal side of the mat, and the handles are attached to each end face, so when moving the mat, it is difficult to pull the handles. When you try to tension it, the part of the bag to which the handle is attached is pulled before the other parts of the bag, and the overall shape of the mat bends into a roughly zigzag shape, causing the tension to become tighter. There is a lot of room for improvement in air mattresses for beds because not only do patients not move easily and smoothly, but they also bend the patient's body from side to side along with the mattress, potentially causing physical damage. It was what was left of.

(Problems to be Solved by the Invention) The present invention was devised in view of the problems of the prior art, and its purpose is to provide an air mat for a bed that is easy to pull,
The goal is to move patients, etc. safely and smoothly.

(Means for Solving the Problem) The technical means of the present invention to achieve the above object is to form a rectangular frame with a side plate having a U-shaped cross section and made of Goyu-biki cloth, Leather fabric with nylon cloth as the outer surface is stretched over the upper and lower surfaces of the frame to form the front and back surfaces, and a plurality of hanging sheets are provided between the front and back surfaces so as to be perpendicular to the longitudinal direction of the front and back surfaces. Cloths are hung at regular intervals, and one or more handles are disposed on the outer surface of the frame on the side perpendicular to the hanging cloths.

(Function) When air is filled into the mat using the technical means described above, the parts of the front and back surfaces to which the hanging cloth is not attached bulge out perpendicularly to the longitudinal direction of the mat. A front surface and a back surface having concave and convex surfaces arranged in a row alternately are formed.

Even when the mat is pulled by the handle when transporting a patient, the frame body, which is formed into a rectangular plane with side plates made of rubber-coated cloth and has a U-shaped cross section, holds the mat in place without losing its flexibility. The back surface, which maintains the shape and is provided with concave and convex surfaces extending in a direction perpendicular to the longitudinal direction of the mat, improves slipperiness during parallel movement of the mat.

(Example) An example of the present invention will be described below.
indicates an air mat, and the air mat A consists of an air mat main body a and a handle b, and the air mat main body a is composed of a frame 1, a front surface 4, a back surface 5, and a hanging cloth 6.

The frame body 1 has monolithic side plates 1a, 1a and elongated side plates 1b, 1b made of rubberized cloth and having a U-shaped cross section, facing each other, and each longitudinal side 1
a'..., 1b'... are pressed against each other to form a substantially elongated rectangular shape in plan, and a hanging cloth 6... is provided in the internal hollow part, and the upper edge 2 and lower edge of the frame 1 are attached. 3, a front surface 4 and a back surface 5 are provided, respectively.

The front surface 4 and the back surface 5 are made of leather fabric with outer surfaces made of nylon cloth larger than the upper and lower surfaces of the frame 1, and the respective edges 4a' and 5a' are the upper and lower edges of the frame 1. 3 will be assigned to each.

A plurality of hanging cloths 6 are installed across the inner wall 4a of the front surface 4 and the inner wall 5a of the back surface 5 at equal intervals so as to be orthogonal to the longitudinal direction thereof, and are suspended using an electric pump or the like. When air is injected from the injection part 7 to inflate the main body a, the hanging cloth 6...
The parts of the front surface 4 and the back surface 5 that are not in contact with the mat body a bulge out perpendicularly to the longitudinal direction.
Concave and convex surfaces x and x' are provided in which concave and convex portions are alternately arranged so as to be perpendicular to the longitudinal direction of the plate.

Although not shown, a built-in pump may be used without any restrictions.

The hanging cloth 6 has approximately the same height as the vertical side 1a' of the short side plate 1a, and has the same height as the horizontal side 1a' of the side plate 1a.
A long side 6 of cloth pieces 6a, 6a made of rubberized cloth or the like and formed into a substantially U-shaped cross section and placed back to back.
a′ and 6a′ are glued together and sewn together to form a substantially I-shaped cross section, and the inner wall 4 of the surface 4
When the upper end 6' and the lower end 6'' are attached to the inner wall 5a of the back surface 5 and the inner wall 5a of the back surface 5, a desired flow path 8, 8 shall be formed.

Two handles b are provided on each side plate on the side where the hanging cloth 6 intersects perpendicularly, that is, on the outer surface of the facing elongated side plates 1b and 1b. and a grip part 10 protruding from the surface of this seat part 9 are integrally formed, and a long side plate 1b that faces the back surface of the seat part 9.
Apply glue to the required locations.

Although the drawing shows two pieces provided only on the long side plates 1b, 1b, the present invention is not limited to this, and they may be provided on the short side plates 1a, 1a as well. The number of grips 10 is arbitrary, and the shape of the grip portion 10 is not limited to the shape shown in the drawings, but may be a ring shape or a rod-like shape perpendicular to the bottom surface 9 without any restrictions.

Therefore, as shown in Fig. 4, in order to transfer a patient lying on an air mat A placed on bed B to an operating room, etc., a patient transfer vehicle C should be placed next to the bed B side, and an attendant should When the person grasps the grip part 10 of the handle b of the air mat A and pulls it, the uneven surface x' of the back surface 5, which is the sliding surface of the air mat A, moves the air mat A in the lateral direction (onto the transfer tool C). The frictional resistance applied when moving in the moving direction) is reduced, and the patient can be smoothly moved in parallel onto the patient transport vehicle C without getting caught, and the patient is moved onto the patient transport vehicle C together with the air mat A.

In addition to the above-mentioned bed placed on bed B in a hospital, for example, when placed directly on the floor at home, even if you want to change the laying position, hold the handle B and move it. The same effect can be obtained if

Although the above embodiment has been described with the air chamber in the form of a single layer, the air mat main body a is made into a two-layer structure, and a large number of minute air blowholes are provided on the surface of the upper layer. Optionally, air is constantly supplied by a compressor or the like, and the air is blown from the blowholes toward the user's body surface to prevent bedsores.

(Effect of the invention) Since the present invention has the above-mentioned configuration, by filling the mat with air, the parts of the front and back surfaces to which the hanging cloth is not attached are perpendicular to the longitudinal direction. It bulges out, and has a front and back surface with uneven surfaces arranged alternately in the longitudinal direction of the mat, and the back surface with the uneven surface improves the slipperiness when the mat moves in parallel, and is made of rubberized cloth. The frame body, which is rectangular in plan and has side plates with a U-shaped cross section, holds the mat in a predetermined shape without impairing its flexibility, making it easy to place the patient transport vehicle next to the bed and pull the mat onto the transport vehicle. It is now possible to provide an air mattress for bed that can be smoothly moved in parallel onto the transport vehicle without causing deformation of the mat body, which can easily occur when moving in parallel with conventional air mats for bed. It is very useful and has high practical value since there is no fear that the patient's body will be deformed into a zigzag shape or the like, causing pain or disability due to bending of the patient's body.
