Description

[Detailed Description of the Invention] The present invention relates to a patient transfer device used in a hospital or the like to lift a bedridden patient from a bed or the like and safely transfer him or her to a stretcher or the like.

In hospitals, etc., when changing the bed of a bedridden patient, transferring a bedridden patient onto a stretcher, etc., or transferring the patient from a stretcher to an operating table, a large number of caregivers are not only required. This required the caregiver to be highly skilled and was a difficult task for the caregiver.
Therefore, from the viewpoint of safety, it is strongly desired that machines be used to perform such labor in place of caregivers.

However, although it is relatively easy to spatially move a bedridden patient (hereinafter referred to as a patient) using power, it is difficult to lift such a patient from a bed, etc., or to move a patient once lifted from the bed. It has not been realized in the past because there are many problems when mounting it on a computer. In other words, when a machine is inserted between the patient's body on the bed and the bed to lift the patient's body, it is extremely difficult to scoop the patient's flexible body without causing discomfort or adverse effects. On the other hand, it was technically extremely difficult to gently place a patient on a bed or the like again once the patient had been lifted.

It is an object of the present invention to solve the above-mentioned drawbacks and provide a patient transfer and transfer device that can safely lift and move the body of a bedridden patient without causing any discomfort or adverse effects on the body of the bedridden patient.

An embodiment of the present invention will be described below, taking as an example a case in which a bedridden patient on a bed is transferred to a stretcher.

The principle of the device of this invention is that a pair of plate-shaped blades are stacked horizontally and fixed at a predetermined distance, and each of these blades is rotatable upward and downward from one side, which is the tip of the blade. An endless belt is wound around the bed, and these belts are rotated in opposite directions by respective driving parts, and the tip of the blade around which the belt is wound is placed between the patient's body on the bed and the bed. Just by lightly inserting it, the patient's body is automatically transferred along with the belt onto the blade. In this case, the structure is such that the relative speed between the belt and the human body, or between the belt and the bed, is zero, so the patient can be transferred and transferred safely without causing discomfort such as rubbing the patient's back or any associated negative effects on the patient's body. will be carried out.

The explanation will be given below based on FIGS. 1 to 7.

As shown in FIGS. 2, 4, and 5, the device 2 of the present invention has a pair of plate-shaped blades 3a, 3b.
and a pair of endless belts 6a, 6b wrapped around each of these blades 3a, 3b, respectively.
And these belts 6a, 6b are connected to blades 3a,
It is composed of a pair of drive devices 7 that respectively move and rotate the drive device 3b along the outer circumferential surface of the drive device 3b.

The blades 3a and 3b are as shown in FIG.
It is a rectangular plate large enough to hold the body of a bedridden patient, and its width is formed to match the height of the human body.One long side is the tip (left side in the figure) and the other long side is the back. It becomes the end. these blades 3
a and 3b are stacked horizontally while maintaining the required spacing (a spacing that allows sufficient insertion of the belts 6a and 6b), and both sides thereof are fixed to a frame 5 shown in FIG. Furthermore, each of these blades 3a, 3b has a belt 6a, extending from its tip to its rear end.
Since the belt 6b is wound around, these belts 6a, 6
In order to reduce the friction of each blade 3a, 3
At the tip of b, needle rollers 4a and 4b are rotatably supported by a frame 5 along the edge thereof, as shown in FIG. These needle rollers 4a, 4
b is the belt 6 by reducing the frictional force.
The tension of belts a and 6b is reduced, and as a result, the belt 6
This is provided to greatly extend the life of parts a and 6b. Further, both upper and lower surfaces of the blades 3a and 3b are coated with Teflon or the like to reduce the coefficient of friction. In addition, these blades 3a, 3
Because the human body is placed on the b, it is desirable that it has strength enough to withstand the weight of the human body and is also lightweight, and its material is preferably a light alloy, resin, or the like.

The belts 6a and 6b are endless belts having approximately the same width as the blades 3a and 3b,
Needle rollers 4a at the tips of blades 3a, 3b,
4b to a drive device 7 installed behind the rear ends of the blades 3a, 3b, and is rotated by the drive device 7 while slidingly contacting the outer peripheral surfaces of the blades 3a, 3b. Therefore, these belts 6a and 6b are made of a thin material such as nylon that has a small coefficient of friction.

The drive device 7 is installed behind the rear end of the blades 3a, 3b as shown in FIG.
A pair of driving pulleys 8a and 8b around which 6b is wound, and this driving pulley 8.
Guide rollers 12a, 12b installed near the belts 6a, 8b to increase the wrapping angle of the belts 6a, 6b
It is made up of.

Furthermore, these driving pulleys 8a and 8b have a motor and a speed reducer built into the cylindrical pulley as shown in FIG. 6, and a shaft 9 protruding from both sides of the pulley.
By fixing a and 9b to the frame 5 and feeding power from the cable 13, the pulley can be rotated freely. Furthermore, this driving pulley 8
For a and 8b, it is also possible to use a type in which the motor and the speed reducer are provided outside the cylindrical pulley.

In addition, rubber rings 11 are provided on the outer peripheral surfaces of the driving pulleys 8a and 8b as shown in FIG. 5 in order to increase the coefficient of friction with the belts 6a and 6b.
a and 11b are ringed. This rubber ring 1
Instead of 1a and 11b, the pulley surface may be provided with fine irregularities. Further, gears 10a and 10b are fixed to the end portions of the driving pulleys 8a and 8b in a meshed state, respectively, and the driving pulleys 8a and 8b always rotate in opposite directions. Therefore, when the belt 6a suspended on the driving pulley 8a moves in the direction of arrow a on the upper surface of the upper blade 3a as shown in FIG. 5, the belt 6b suspended on the driving pulley 8b also moves on the lower blade 3b. Move the bottom surface of in the same direction a. On the contrary, driving pulleys 8a, 8
If b rotates in the opposite direction, belts 6a and 6b also rotate in the opposite direction to a direction. In this way, the upper belt 6a and the lower belt 6b always move in the same direction on the upper surface of the blade 3a and the lower surface of the blade 3b.

Such a device 2 is actually used by being fixedly installed on a trolley or the like, and as shown in FIG. automatically transfers the human body onto the blade 3a. In other words, when lifting a human body from the bed 1, the belt 6 is
a and 6b are rotated in the direction of the arrow a in the figure on the upper surface of the blade 3a and the lower surface of the blade 3b, and the tips of the blades 3a and 3b are connected to the human body and the bed 1.
Insert a little bit in between. At this time, if the moving speed of the belts 6a and 6b with respect to the blades 3a and 3b is v, then at the tips of the blades 3a and 3b, the upper belt 6a moves from the lower surface of the blade 3a to the upper surface, and the lower belt 6b moves from the lower surface of the blade 3a to the upper surface. 3b
Since both are fed out from the upper surface to the lower surface at a speed of v, the upper belt 6a and the human body, and the lower belt 6b
The relative speed of the bed 1 becomes zero, and the blades 3a and 3b move forward at a speed of v with respect to the belts 6a and 6b in the direction of the arrow b in the figure while sneaking between the human body and the bed 1. In this way, the human body can be transferred onto the blade 3a together with the belt on the bed 1 without causing any friction between the human body and the bed. On the other hand, once the blade 3a
When transferring the human body placed on the bed to bed 1, etc., reverse the above operation and tighten the belts 6a, 6.
By rotating b in the opposite direction to the above, it can be easily placed on the bed 1.

In this way, according to the present invention, it is possible to safely and automatically transfer a patient from a bed, etc. to a stretcher, etc. without causing any adverse effects or discomfort on the body of a bedridden patient. It is extremely useful.
