Abstract

PROBLEM TO BE SOLVED: To allow anyone to wind a bandage rapidly and neatly. SOLUTION: The width of a bandage is adjusted with an adjustment screw and the winding speed of the bandage is adjusted using a switch 16. The bandage is passed between plates and put on a rectangular, partly bending bar 4 from below, and a lid 6 equipped with a plate is lowered. The bar carrying the bandage makes close contact with rollers 1, and as the bar starts to rotate the rollers also start to rotate, winding the bandage around the bar. After the bandage has been wound around the bar, the lid is raised. Then the bar stops rotating. Finally, the partly bending rectangular bar is bent by hand and the bandage is drawn out from the bar. Even if the bandage kept bent is wound around the bar 4, it can be rewound by turning the adjustment screw 12 and unwinding it.

Description

DETAILED DESCRIPTION OF THE INVENTION

In the present invention, a bandage is placed on a square rod 4 from below, sandwiched between the plates 2 and 3, and at the same time, a roller plate 8 having a different size is wound on the rod 4.
Further, the present invention is intended to be used by many people such as nurses, doctors and patients in many other places such as nurse stations and hospital waiting rooms.

Conventionally, bandages have been rolled up by hand, so it takes a long time to roll up the bandage and it is difficult to roll up the bandage cleanly. In addition, because it is several meters long, if you wind more than a couple of them, your hands will hurt and you may get irritated. Therefore, it was impossible to wind up quickly and neatly.

[0003] The present invention can be placed on a desk or the like,
Since the operation is simple, it is possible to easily and quickly roll it up to anyone, and the operation will be briefly described with reference to the drawings. First, the width of the bandage to be passed is set with the adjusting screw 5, and the speed is adjusted. After setting the bandaging speed with the switch 16, the bandage is fixed between the plate 2 on which the bandage is fixed below and the plate 3 attached to the lid 6 which can freely move up and down. When the lid 6 is lowered and the lid 6 is lowered, the rod is automatically brought into close contact between the two rollers 1, and at the same time, the switch 18 is pressed and the rod 4 is rotated. It is to wrap. This solves all of the conventional problems of time-consuming winding, difficulty in winding cleanly, pain in hands, and frustration.

In order to adjust the width of the bandage, a plate 10 is formed by using two screws 13 having opposing right and left screws and turning an adjusting screw 5 for adjusting both screws 13. It is adjustable and it is possible to wrap a bandage with a minimum width of 3 cm and a maximum width of 10 cm. The bandage has a maximum radius of 5c.
m can be wound.

When the bandage is shrinking or in order to make it available to many age groups, an adjustment switch 16 can be used to increase or decrease the rotation speed of the bandage.
The speed is divided into three stages, large, medium and small. Further, in order to prevent the bandage from being bent and wound, the tip of the plate 3 is sharpened, or a member 14 attached to the plate 2 is used. Further, the lid 6 and the plate 3 are made transparent so that the bandage can be seen.

[0006] The roller 1 is provided with a bearing for smooth rotation, and a spring-loaded box 19 is used to attract the two rollers 1 to a narrow width between the rods. In addition, the hinge plate 7 is used to move the roller plate 8 up and down. The roller plate 8 is made heavy so that the roller 1 comes into close contact with the rod 4.

[0007] The present invention utilizes a predominantly plastic material. Further, in order to prevent the rod from running idle and preventing the bandage from being wound, the surface of the roller 1 is made of a rubber-like material, and the surface of the plate 2 is made of a sponge-like material. Further, the rod 4 is made of a plastic material so that it can be easily pulled out. In addition, the main parts use metallic materials.

[0008] A tension coil spring 11 is attached to the bent portion of the rod 4 which bends on the way so that the rod 4 can be bent freely. Further, since the rod rotates clockwise, a clockwise tension coil spring is used. This allows
When rotating, the bend is less likely to bend.

Box 9 has one output conversion device inside,
It contains a DC motor, a gear for adjusting the two plates 10 that make up the width of the bandage, a gear for turning the bar 4, and the like. If this is written in a diagram, it becomes difficult to see it, so the diagram is omitted.

If the bandage is incorrectly folded and wound, the bandage can be rewound by manually turning the adjusting screw 12 in the opposite direction to the rotation of the rod 4, ie, counterclockwise.

The bandage to be put on the bar 4 can be wound as long as it can be put on the bar 4 from below. However, if the end of the bandage is cut into two pieces and it is used as a string, the part not cut into two pieces must be wound on a stick. Because if you put the string on the stick 4, when you pull out the bandage from the stick 4 after winding,
This is because the bandage that has been rolled up may be unwound.
