Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a bed turning device that enables bedridden patients to turn over in bed.

(Prior Art) Some conventional beds are capable of raising the upper body of a sick person lying on the bed.

(Problem that the invention aims to solve) However, although it is necessary to turn over the bed in order to prevent bedsores and change clothes, no bed has been provided so far that allows the patient to turn over without causing any pain. It had not been done. As a result, attendants and nurses had great difficulty turning patients over.

The purpose of this invention is to provide a bed that allows sick patients to turn over as necessary without causing any pain.

(Means for solving the problem) In other words, this invention is based on the back base frame provided at the back of the bed. A pair of left and right movable frames are attached so that they can rotate counterclockwise, and in conjunction with the rotation of the movable frame, an extrusion roller that rises from below the movable frame and gradually projects to the outside of the movable frame is installed. The gist is that it is attached to each movable frame.

(Function) When lifting one of the patient's left and right sides, for example, the right side, the right side movable frame is rotated. The movable frame rotates counterclockwise using the left end as a fulcrum, and the extrusion rollers that work with the movable frame rise from their initial position below the movable frame and gradually protrude to the outside of the movable frame.

The patient is therefore tilted on his left side by counterclockwise rotation of the movable frame. At the same time, the pushing rollers that were initially under the movable frame rise and gradually protrude to the outside of the movable frame in conjunction with the rotation of the movable frame, so that the sick person can be lifted up so that his back can be rubbed. You can easily turn over.

(Example) This invention will be explained below based on the drawings. Note that since this turning device is provided symmetrically, the left side thereof will be mainly explained.

Reference numeral 1 denotes a back base frame of the bed, and a reinforcing frame 2 is fixedly installed below it. This back machine frame 1 is attached to the back (upper body side) of a bed base frame with legs (not shown), and has a bracket 3 protruding from the front and back center.

4a is the left movable frame of a pair of left and right movable frames, and a pin 5 protruding from the right end is connected to the bracket 3.
By fitting into the shaft hole, it is rotatably supported by the back machine frame 1. 6 is a driving rod, which is a movable frame 4a.
The rod protrudes downward from approximately the center of the hydraulic cylinder 7, and its lower end pivotally supports the rod tip of a hydraulic cylinder 7 whose base is pivotally supported on the right side of the reinforcing frame 2 (ie, below the right movable frame 4b).

A pair of support rods 8 project forward and downward from the left side of the movable frame 4a, and a support shaft 9 is loosely fitted into the lower end of each of the support rods 8. 10 is the upper connecting rod,
The upper end portion is fixed to the support shaft 9 at approximately the center thereof. A bracket 11 projects downward from the center of the reinforcing frame 2, and the right end of a lower connecting rod 12 is pivotally supported by a pin 13 at the lower end of the bracket 11. The left end of the lower connecting rod 12 and the lower end of the upper connecting rod 10 are connected and supported by a pin 14.

Reference numeral 15 denotes a pair of front and rear cylinders, into which the right end of an operating rod 16 whose left end is fixed to the support shaft 9 is loosely fitted, and the tip of a mounting rod 17 protruding from the cylinder 15. Push-out rollers 18 are attached to both sides. These operating rods 16
The cylinder 15 and the mounting rod 17 are coaxially attached. Furthermore, the upper connecting rod 10 and the operating rod 16
The opening angle is fixed at 120 degrees.

19 is a front and rear 1 attached to the lower part of the movable frame 4a.
This guide frame 19 is a pair of guide frames, and the guide frame 19 is formed into a substantially dogleg shape convex downward, with a set of two upper and lower plates. Rollers 20 attached to both sides of the left end of the cylinder 15 are rotatably fitted into the guide frame 19.

Now, the operation of the movable frame 4b shown by the imaginary line in FIG. 1 will be explained.

Due to the operation of the hydraulic cylinder 7, the movable frame 4b rotates counterclockwise in a semicircle upward with the pin 5 as a fulcrum. As the movable frame 4b rotates, the support shaft 9 also rotates while being regulated by the upper and lower connecting rods 10 and 12. Therefore, the operating rod 16 moves back and forth within the cylinder 15, and the extrusion rollers 18 are moved upward by the rollers 20 guided by the guide frame 19.

At this time, the extrusion roller 18 moves upward,
Further, upper and lower connecting rods 10, 12, a guide frame 19, etc. are formed so as to gradually protrude outside the right side movable frame 4b and move on the straight line A. That is, if the pushing rollers 18 are configured to move on the straight line A, the patient can be lifted up as if rubbing the patient's back with both hands, and the patient can be easily turned sideways without causing any pain. be. Of course, such an extrusion roller 18
It is also possible to perform this movement using a cam device or the like.

Although the illustrated embodiment uses the hydraulic cylinder 7 to drive the movable frames 4a and 4b, it is also possible to use a motor or use manual power.

Further, a mattress or a futon is placed on the movable frames 4a and 4b via a back floor plate, but this floor plate requires a groove for the extrusion rollers 18 to enter and exit.

(Effect) Since the push-out roller can be lifted up by rubbing it from the back with both hands, it is possible to easily turn over the patient without causing any pain.
