Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a transport device for sick, injured, physically disabled, etc. (hereinafter collectively referred to as "patients"), and can be widely used in hospitals and rehabilitation facilities. It is.

<Prior art> A stretcher (carrier) is used when moving a person who is unable to walk by themselves from a hospital bed for treatment or other purposes. Commonly used stretchers require several people to transfer patients, which puts heavy labor on caregivers. To solve this problem, a stretcher was proposed in 4H11 that uses a belt to allow patients to be loaded and unloaded without relying on the physical strength of the caregiver.

Special Publication No. 5G-24536, Special Publication No. 5G-3429
These are those described in Publication No. 81, Japanese Utility Model Publication No. 57-50015, and the like. By the way, these stretchers employ a structure in which a plate-like structure equipped with a belt is pushed out from the main body and inserted between the patient's body and the bedclothes. In such a structure, there is a high possibility that the end of the plate-like structure gets caught in the unevenness of the bedding. If a large amount of resistance occurs due to snagging or other causes, an abnormality will occur in the power system due to overload. Alternatively, the main body may be pushed away by the reaction, leading to the undesirable result that the belt cannot be fully inserted under the patient's body.

〈Purpose of Purpose〉 The invention is to place a lifting belt under the patient's body.
The purpose of the present invention is to provide a patient transport device with a large slip-in capability.

<Configuration of the Invention> In the present invention, a scoop belt for scooping up a patient is provided on the upper surface,
A self-propelled movable deck equipped with an O-ra on the lower surface is mounted on a moving table so that the movable deck crawls with its own blade and crawls under the patient's body. Then, a rail is attached to the support deck that supports the movable deck, and a moving guide is fixedly attached to the movable deck to connect it to the rail, so that the movable deck can travel a certain distance z1.
In addition to being movable, the movable deck is given the ability to follow the unevenness of the bedding by FF I-' in lifting up from the support JN1i deck.

<Example> An example will be described below based on the figures. In Figure 8,
1 is a bed stand, 2 is a mattress, 3 is a futon, and 4 is a patient lying on the futon 3. Reference numeral 10 denotes a transportation device according to the present invention, and its main body is essentially a moving platform 11 constructed from a combination of steel materials. The structure will be explained with reference to figures other than FIG. Rod-shaped handles 12 and 13 are provided at the longitudinal ends and side surfaces of the movable platform 11, respectively.

The moving platform 11 is supported by two sets of wheels. - set is a group of wheels for normal running, and is composed of a pair of front width wheels 14i4 and a pair of rear wheels 15°15. The rear wheels 15.15 are swivel wheels. The other set is a group of wheels for lateral movement, and one pair of elevating wheels 1 are arranged on both sides of the moving platform 11 in the longitudinal direction.
6. Consists of 16', 17', and 17. Each elevating wheel is raised and lowered by an electric actuator 18, and the fourth stage is raised to a higher position than the normal traveling wheel group. In addition, each elevating wheel faces in the direction perpendicular to the longitudinal direction of the movable platform 11) (ijlΦj. 19, 2
0° ρ1 is the support plate that constitutes the upper surface of the movable table 11.
- Line up in order in the longitudinal direction of the movable platform 11 with ki. The upper surfaces of the support decks 19, 20, 21 normally constitute a single horizontal plane, and are each inclined at a predetermined angle within a vertical plane that includes the longitudinal direction of the movable platform 11, if necessary. The following support structure makes this possible. First, the support deck 19 is connected to the support deck 2.
One end adjacent to 0 is pivoted to a slider 22. The slider 22 has rails 23 and 2 provided on the side edge of the moving table 11.
3, and only linear movement parallel to the longitudinal direction of the moving table 11 is possible.

The slider 22 is moved by an electric actuator 24 fixed to the moving table 11. Further, the substantially central portion of the support deck 19 and the slider 22 are connected by an electric actuator 25 to support the support deck 19. Support deck 20
is installed on the movable platform 11 (P1=the central part is pivotally supported by the support column 26.26.Furthermore, an electric actuator 27 connects between the end near the support deck 19 and the movable platform 11.Support The deck 21 is attached to the end of the support deck 20 by a hinge 28, and the vicinity of the center thereof and the movable platform 11 are connected by an electric actuator 129.The electric actuator 18, 24, . .'27.
29 is similar to Jyatsuki, in which Rondo is slowly moved in and out with strong force. A battery 30 attached to the side of the moving table 11 is responsible for supplying current.

Support deck 19.20. , 2'1, each pair of movable decks 31, 32, and 33 are placed on the upper surface. Each movable deck has a pair of scoop belts 3 on the top and bottom surfaces.
4.34 and crawlers 35.35, some of which protrude outside the support deck. The scoop belt 34 and crawler 35 are all oriented perpendicular to the longitudinal direction of the carriage 11. Each movable deck 31, 32, 33 has a motor box 36 at its end, in which a motor 37, 38 with a reduction gear is housed. The electric motor 11t37 is connected to the sprocket 39 of the scoop belt 34, and the electric motor 38 is connected to the sprocket 40 of the crawler 35 by a non-slip winding transmission means such as a chain or a timing belt to transmit rotation. The power source for the electric motors 37 and 38 is a battery, as in the case of the electric actuator. In addition, each movable deck 31.3'2°, 133 has a moving guide 4 in the center.
1 is permanently installed.

The mold movement guide 41 is a rectangular cup-shaped member with a slit on the lower surface, and each support deck 19.20゜'J\L1
It receives a rail 42 fixed to the top surface of the rail. rail 4
The shape of No. 2 is shown in FIG. 7. The portion far from the J0 motor box 36 has an overhanging portion 43 at the upper end, and this overhanging portion 43 prevents the moving guide 41 from coming off upward. However, there is a space between the overhanging portion 43 and the lower edge of the moving guide 41, and the movable deck 31, 32, 33 can float within a certain height range. This means that the movable deck can tilt relative to the support deck as shown in FIG.

In the illustrated embodiment, consideration is given only to preventing the moving guide 41 from coming off upward, but in order to prevent the moving guide 41 from coming off in the moving direction, an appropriate retaining means may be provided at the end of the moving guide 41. .

Next, the action will be explained. To move patient 4 to another location,
First, the transport device 10 is placed parallel to the bed 1. At this time,
The transport device 10 may be remote from the bed 1. Then, the electric actuator 18 causes the lifting wheels 16. ．． 17, lift the front and rear wheels 14 and 15, and support the transport device 10 with the lifting wheels 1 (3 and 17).Then, push the transport device 10 with the Q handle 13, and move the Move it to the side of the bed 1. Now, when the lifting wheels 17 are retracted as shown in FIG. The end falls on Futon 3.

The inclination and height of the transport device 10 are controlled by the degree of protrusion of the lifting wheels 16 and 17. Next, the electric motor 38 is driven to move the movable deck 31. '32.33 crawler 35 in the direction of advance
move. At the same time, the scoop belt 34 remains stationary so that its upper surface flows toward the motor box 36. The movable decks 31, 32, 33 are guided by the rails 42 and the movable decks 1
Advance from the longitudinal side of 1. Because of the floating structure, the movable decks 31, 32, and 33 move in between the futon 3 and the patient's 4 body while closely following the ups and downs on the path.

If the feeding speed of the scoop belt 34 is made equal to the advancing speed of the movable deck, the entry can be carried out smoothly.

When the movable decks 31, 32', 33 are completely under the patient 4, the crawler 35 is stopped and only the scoop belt 34 continues to operate. Then, the patient 4 is carried towards the back of the movable deck 31, '32.33, as shown in FIG. When the patient 4 reaches a predetermined position, stop the scoop bar 34, move the protrusion bar 35 in the opposite direction, and divide the movable deck 31 by 11. ．． 32.
33 also retreats -1 while supporting patient 4 as shown in Figure 7. When the movable deck 31, 32, 33 has retreated to a position where there is no problem in terms of weight balance, lift wheel 1
7 and return the transport device 10 to horizontal position. Thereafter, the transport device 10 is pulled away from the bed 1, the lifting wheels 16, 17 are pulled up, the transport device 10 is returned to support by the front and rear wheels 14, 15, and the transport device 10 is moved to the destination.

When placing patient 4 on another or original bed, the procedure is reversed. That is, the movable deck 31, 32, 33 is placed on the bed and advanced until the end reaches the center of the bed. After the movable deck stops, the hookup belt 34 is moved in the opposite direction to move the patient 4 toward the bed. When the patient 4 reaches the end of the movable deck, the scoop belt 34
When the deck is moved backward, the patient 4 is left in that position.

After scooping up the patient 4 with the movable decks 3'l, 32, 33, when the patient 4 is desired to take an upright posture, the transport device 10 is transformed as shown in FIG. 12. In other words, move the slider 22 to the right side of the figure and move the electric actuator 25.
The support deck 19 is flipped up, and the connected body of the support decks 20.21 is bent into a figure-eight shape by the electric actuators 27.28. Patient 4 then leans his head and back against the movable deck 31, and places his buttocks and the back of his upper legs on the movable deck 32.
The movable deck of the present invention can be supported in a posture where the toes are placed on the movable deck and -y Ki33. In the present invention, since the movable deck has a self-propelling means called a crawler, it can be supported even if there is an obstacle. It has a higher ability to reach the destination than those that step over it and push it later. Furthermore, since the movable deck is guided by rails, it does not take a wrong course, and since it is connected to the rails in a floating manner, it can adapt well to the height of the bed and the undulations of the bedding.
