Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of a patient transfer vehicle used when a patient who cannot move by himself is taken off the bed and transferred to another place such as a bathhouse, or when the patient is put on the bed from another place.

Prior Art As a prior art, for example, a device shown in Japanese Patent Application Laid-Open No. 54-66591 has a movable stretcher body 1.
An upper frame 2 is provided on top of the upper frame 2, and a transfer frame 3 is provided on the upper frame 2 so as to be able to slide with respect to the upper frame 2. A belt 4 is stretched on the transfer frame 3, and both ends of the belt 4 are stretched. It is attached to a rod 5 placed along the longitudinal direction of the transfer table 3. The rod 5 is configured to be hooked to the upper pedestal 2 with a pin 17 when a patient is transferred onto or off the transfer table 3.

Problems to be Solved by the Invention In the conventional device of the invention, when the transfer table 3 is advanced or retracted onto or from the bed 6, it is impossible to move the transfer table 3 forward or backward with the back side of the transfer table 3 in contact with the top surface of the bed 6. Since friction occurs between the bed 6 and the back surface of the transfer table 3, it can be lowered. Therefore, the transfer table 3 is placed slightly higher than the bed 6, and the transfer table 3 is placed on the bed 6 with a slight gap between the back surface of the transfer table 3 and the top surface of the bed 6.
must advance and retreat. In order to maintain this clearance, it is necessary to make the stretcher main body 1 heavy so that it does not tilt. Since the stretcher main body 1 is made heavy, it is difficult to move the entire device.

Furthermore, when a patient is placed on the transfer table 3 which is slidably gripped on the upper part of the upper pedestal 2, the gripping mechanism must be made strong because the patient slides and protrudes sideways from the upper pedestal 2 to a large extent. . As a result, the device became increasingly large and expensive to manufacture, and its weight increased, reducing operability.

Also, when the transfer table 3 advances toward the bed 6 placed on the side of the transfer vehicle, the belt 4 located on the back side of the transfer table 3 is directed in the same direction as the advance direction of the transfer table 3. and slide on the outer periphery of the transfer table 3. When the transfer table 3 attempts to scoop up a patient lying on the bedding spread on the bed 6, the belt 4 contacts the bedding, and the belt 4 pushes the bedding in the advancing direction of the transfer table 3, causing the patient to be pushed away. There was a drawback that the bedding was placed between the patient and the transfer table 3, which prevented the patient from being placed on the transfer table 3.

Also, move the patient on belt 4 from the transfer vehicle to bed 6.
Transfer platform 3 has advanced to the top of bed 6 to unload it to
When retracting toward the upper frame 2, the belt 4 on the back side of the transfer table 3 slides on the outer periphery of the transfer table 3 in the same direction as the retracting direction of the transfer table 3. Therefore, when the belt 4 contacts and presses the bedding, the belt 4 pulls the bedding toward the upper pedestal 2, resulting in damage to the bedding and foreign matter getting caught in the lower part of the transfer table 3, causing the transfer platform to malfunction. .

Therefore, the object of the present invention is to provide a patient transfer vehicle that allows patients to be loaded and unloaded with little effort without damaging the bedclothes, and that is easy to move even in narrow spaces.

Means for solving the problem The present invention includes a transfer table 3 on which a human body is placed, and a transfer table 3 on which a human body is placed.
It consists of an upper pedestal 2 having a sliding mechanism 7 for horizontally slidably gripping and sliding the transfer table 3, and a stretcher main body 1 supporting the upper pedestal 2. A belt 4 on which a human body is placed is slidably covered with respect to the transfer table 3.
The base end and the terminal end of the winding are fixed to the upper frame 2 at a lower position of the transfer stage 3 to form a patient transfer vehicle.

Example Stretcher body 1 with wheels 15 at the bottom
An upper pedestal 2 is provided on the top of the mount 2, which grips a sliding mechanism 7 that holds the transfer table 3 so as to be slidable in the horizontal direction.

The stretcher main body 1 is composed of a support section 9 and a leg section 10, which are made up of a screw shaft mechanism or the like, which can be freely expanded and contracted by rotating an elevating handle 8.

The transfer table 3 is made of a rectangular flat plate with an appropriate thickness, and rollers 16 having the same diameter as the thickness are provided on both side surfaces of the long side of the rectangular flat plate in parallel with each other.
The shaft ends of the rollers 16 are supported by extended sides of both short sides of a rectangular flat plate.

The belt 4 is wound in the transverse direction of the transfer table 3 from the front surface to the back surface, and a small portion where the belt 4 is not wound is left at both ends of the transfer table 3 in the longitudinal direction. In this part, a rack 11 is carved in the lateral direction of the back surface of the transfer table 3.

As shown in FIG. 3, the transfer table 3 is held by the upper frame 2 so that both longitudinal ends of the transfer table 3 can be slid in the transverse direction of the transfer table 3. As shown in FIG. 4, the upper pedestal 2 is formed into a rectangular parallelepiped having a width that is approximately one-third of the width of the short side of the transfer table 3, and is positioned below and parallel to the longitudinal direction of the transfer table 3. . A starting end of the belt 4 is fixed to one side of the upper frame 2 in the transverse direction, and a terminal end of the belt 4 is fixed to the other side.

A long shaft 12 is installed in the longitudinal direction inside the upper mount 2, and sliding handles 13 for rotating the long shaft 12 are provided at both ends of the long shaft 12 protruding to the outside of the upper mount 2.
is attached. The long shaft 12 is provided with a pinion 14 that meshes with the rack of the transfer table 3.

Effect The operation of the present invention will be described below.

First, when loading the patient on the belt 6 onto the transfer vehicle,
The height of the transfer table 3 is adjusted using the lift handle 8, and the height from the floor to the back surface of the transfer table 3 is set to be slightly higher than the belt 6. Next, the transfer vehicle is brought close to the bed 6, and the sliding handle 13 is turned to cause the transfer platform 3 to protrude toward the bed 6.

The rotational force of the sliding handle 13 is transmitted to the long shaft 12, and the rotational force of the pinion 14 attached to the long shaft 12 is further transmitted to the rack 11 of the transfer table 3, and the thrust applied to the rack 11 causes the transfer table to move. 3 slides horizontally to the side and protrudes.

When the transfer table 3 advances onto the bed 6, the transfer table 3
Since one end of the belt 4 hanging on the transfer table 3 is fixed to the upper frame 2 on the back side of the advancing side, it does not move relative to the upper frame 2, and only the transfer table 3 slides in the advancing direction. move. As the transfer table 3 moves, the belt 4 on the surface of the transfer table 3 is pulled to the back side of the transfer table 3 while rotating the rotatable roller 16, and as a result, the belt 4 is moved with respect to the transfer table 3. The belt 4 moves in the direction in which the platform 3 moves. The belt also moves on the front and back sides of the transfer table 3 as described above. Therefore, when the transfer table 3 advances onto the bed 6, even if the belt 4 on the back side of the transfer table 3 comes into contact with the bedding on the bed 6, it presses the bedding and advances.

Next, the patient is placed on the transfer table 3 that is advancing onto the bed 6 or on the transfer table 3 that has completed its advancement. After placing the patient on the transfer table 3, the sliding handle 13 is reversely rotated to move the transfer table 3 toward the upper frame 2. During this retraction, the belt 4 on the front surface of the transfer table 3 slides in the retracting direction with respect to the transfer table 3, and the belt 4 on the back surface of the transfer table 3 does not slide with respect to the transfer table 3. Therefore, the patient placed at the end position of the transfer table 3 is moved in the retracting direction on the transfer table 3 at the same time as the transfer table 3 is withdrawn, and is positioned at the center side of the transfer table 3. Also transfer table 3
Even if the belt 4 on the back surface is in contact with the bedding, the bedding is moved in the direction of entering and exiting a transfer table 3 without being pulled.

The patient placed on the transfer vehicle is moved to a desired location by an assistant moving the transfer vehicle.

When lowering the patient onto the bed 6, the operation to place the patient from the bed 6 onto the transfer vehicle described above is reversed. That is, by operating the lift handle 8, the transfer table 3
The height of the patient is slightly higher than the bed 6, the transfer table is brought into contact with the bed 6, the sliding handle 13 is operated to advance the transfer table 3 onto the bed 6, and the patient is lowered onto the bed 6 later. . When the transfer table 3 is slid onto the bed 6, the belt 4 on the surface of the transfer table 3 moves in the moving direction of the transfer table 3 relative to the transfer table 3, and the transfer table 3
The patient placed in the center of the transfer table 3 is moved to the end of the transfer table 3.

Sliding handle 13 after lowering the patient to the bed 6
is rotated in the opposite direction to move the transfer table 3 toward the upper frame 2 and to separate the transfer table from the bed 6.

Since the transfer table 3 slides in both left and right directions with respect to the transverse direction of the transfer table 3, it is possible, for example, to place a patient on the right side of the transfer table and unload the patient from the left side of the transfer table. You can also do it.

Effects of the invention The transfer table that slides from side to side is wrapped in a belt, and the belt is fixed to the upper pedestal located on the back of the transfer table, so the belt can be moved by sliding the transfer table. Since they are carried out simultaneously, the transfer table and belt can be moved simultaneously by rotating the sliding handle, simplifying the structure and eliminating the need for operations such as inserting pins, making handling easier.

Furthermore, the belt on the surface of the transfer table slides in the advancing direction relative to the transfer table when the transfer table advances onto the bed, and the belt moves when the transfer table retracts from the bed toward the upper frame. Since it slides in the direction of withdrawal from the stage, when loading a patient, the patient placed on the edge of the stage can be moved to the center of the stage, so the extent to which the stage protrudes from the upper stage is limited. It may be less. Furthermore, since the transfer table can be moved while the belt on the back side of the transfer table is in close contact with the bed, a part of the stretcher main body does not lift up from the floor surface when transferring a patient. Furthermore, when the patient is taken off the transfer table, the patient placed in the center of the transfer table moves to the edge of the transfer table, so that the caregiver can easily take the patient down. Therefore, unlike conventional devices, there is no need to make the entire device heavy in order to prevent it from tipping over.
In addition, since the sliding distance of the transfer table is short, the mechanism for gripping the transfer table is simple and has a simple construction, making the device lighter and easier to handle and move. The workload has been significantly reduced.
