Description

[Detailed Description of the Invention] This invention relates to a traction bed with pillars, and more particularly to a traction bed in which the patient's pillars are pulled with a force commensurate with the patient's weight.

The most common conventional method of towing a pillar is to wrap a band around the neck, legs, or waist, connect a rope to this band, and pull the rope with a weight, motor, etc.

The biggest disadvantage of this method was that it took time and effort to attach the towing band and hang the rope, making it difficult to tow the tow easily, and it was difficult to tow the tow while sleeping.

In other words, with this method, it is necessary to wear a band every time the patient is towed, which is inconvenient if the patient has to be towed 18+ times at home. Because they were moving and dangerous, they could only be towed under close supervision.

Furthermore, the optimal value of the lapel gravitational force is determined based on the patient's weight, for example, 1/8th of the patient's body weight. It was necessary to adjust the traction force of the weight and motor.

In order to eliminate these drawbacks, the present inventor developed a traction bed in which the patient pulls a column with his or her own body weight.

This traction bed is made by dividing the platform on which the patient lies down, and attaching the divided platforms to an inclined frame so that they move away from each other when a load is applied. Now, the patient can now pull the pillar by simply lying on the bed without using ropes or bands, using a traction force that corresponds to his or her own weight.

However, in a traction bed with this structure, the column is pulled by the frictional resistance between the platform and the patient, so when the patient stands on the platform or moves on the platform, the platform splits. Leave in places.

Therefore, at this time, it is necessary to bring both of them close to each other in some way.

Generally, both platforms are adjusted by springs so that they approach each other when no load is applied, so that when the load on the platform is removed, they approach each other.

Therefore, conventionally, for example, frames that do not touch the platform are placed on both sides of the platform, and the patient places both hands on these frames to raise the upper body and remove the load on the platform on which the patient's upper body rests. At the same time, the lower body was lifted up a little to reduce the load on the platform on which the lower body rests, and springs were used to bring the two platforms closer together.

With this structure, you cannot approach the platform without raising your upper body; in other words, you cannot approach the platform while lying down on the platform, so even if you are close to the platform, it is easy to move away when you are lying down. There was a drawback.

This idea was developed to eliminate this drawback.
An important purpose of this invention is to provide a tow bed that allows the patient to easily access the platform while lying down.

Hereinafter, embodiments of this invention will be described based on the drawings.

The traction bed shown in FIGS. 1 and 2 consists of a platform 1 on which a patient lies, a bed frame 2 to which this platform 1 is attached, and a pulling rope that pulls the platform. .

The stage 1 is set at the middle of the longitudinal direction, preferably as shown in FIG.
The lower frame 3 is tilted parallel to the inclined frame 4 so that the lower frame 3 is divided into two parts at the center or almost the center and the upper surface is horizontal, and the wheels 5 are rotatably attached to the lower frame 3. The pillars are pulled by the wheels 5 rolling along the inclined frame 4.

It is preferable that the upper surfaces of the two divided platforms 1 are located on the same plane at any position.

To achieve this, for example, as shown in FIG. This guide rod 6 fixes a linear motion bearing 7 that is movable only in the axial direction.The guide rod 6 slides in the axial direction inside the linear motion bearing 7, so that the upper surfaces of the several units 1 are aligned with each other. Hold it horizontally.

The two divided platforms 1 are connected to each other by elastic bodies such as tension springs 8, and both ends are also connected to the frame 2 via the tension springs 8.

The tension spring 8 holds the platform 1 in a position where both ends thereof do not touch the frame 2, and has the function of drawing the two divided platforms 1 toward each other.

As shown in Figures 1 and 2, when the platform 1 is placed on the inclined frame 4 via wheels 5, the platform 1 moves smoothly and pulls the column with extremely little resistance. do.

However, it is also possible to connect the platform to the tilting frame in a slidable manner without using the wheels 5.

One end of the pulling rope 17 is connected to the platform 1 on which the upper body is placed, and this is hung over a movable pulley 15 attached to the other platform 1 and a pulley 16 attached to the frame 2, and the pulling rope 17 is connected to the platform 1 on which the upper body is placed. , a hand-held handle 18 is connected.

In the tow bed shown in FIG. 3, one movable pulley 15 is attached to each of the several beds 1, one end of the pulling rope 17 is connected to the platform 1 for the upper body, and the tow bed itself is attached to the several movable pulleys 15. It is hung on the movable pulley 15 and the pulley 16 of the frame, and the handle 1 at the end
8 pulls both cars closer to 1.

The pulling rope 17 shown in FIG. 1 pulls the lower body platform 1 with a stronger force than the upper body platform, so it is convenient when a heavier load is applied to the lower body. The rope 17 has a feature that the force of pulling both the beds 1 and the patient in the longitudinal direction of the bed is balanced, and the patient can be pulled towards the bed 1 without shifting the position.

The frame 2 of the bed has inclined frames 4 on both sides, as shown in FIG. 2, and the inclined frames 4 are arranged so that when a vertical load is applied to the platform 1, both the platforms 1 slide away from each other. The dividing portions of the loading platform 1 are shaped like high chevrons.

The inclination angle of the inclination frame 4, that is, the angle with the horizontal plane, is
The larger this value, the stronger the traction force, but generally it is 5 to 3
The angle is determined to be 0 degrees, preferably about 10 to 20 degrees.

The inclined frame 4 has a rail 10 on its upper surface, as shown in FIGS. 2 and 4, so that the wheels 5 can roll along it.
are either fixed or have a C-shaped cross section, with wheels rolling on the inside.

The platform 1 is divided into two parts at a point slightly shifted to one side from the center.
If both platforms 1 are not subjected to equal vertical loads, the forces with which both platforms 1 are moved along the inclined frame by the vertical loads are not equal.

This is because the force by which the platform 1 is moved along the tilted frame 4 due to the vertical load W is W +1 sin, ignoring frictional resistance and assuming that the tilt angle of the tilted frame is θ.
θ, so if the vertical loads of both platforms 1 are different and the inclination angles are equal, the forces with which both platforms 1 are moved along the inclination frame are different.

To make this equal, for example, as shown in Figure 1,
If the left platform 1 on which the head is placed is short and the load applied thereto is light, the inclination frame 4 on which the left platform is placed may be formed to have a large inclination angle.

If both platforms 1 are pulled in opposite directions and with equal force, even if a patient is placed on the platform, both platforms will not move only to one side.

However, since both platforms are connected to the frame 2 via a tension spring 8 that generates a traction force proportional to the amount of displacement, even if unequal traction forces act on both platforms, the platform 1 can be moved vertically. Needless to say, it is possible to not make it contact the frame 9, that is, to position the support base 1 in a state where it is pulling the column.

In addition, as shown in FIG. 1, a tilted frame 1 with a downward slope toward the end is installed on the left platform 1 at the location where the head is placed.
1, and attach a head platform 13 on which the head is placed via wheels 12 that roll along this inclined frame 11, the head platform 13 will simultaneously pull the column. It can also pull the patient's neck.

In FIG. 5, one platform 1 is fixed to the frame, and only the platform 1 on which the upper body is placed is movably placed on the inclined frame 4. 1, which is hung on a pulley 16 attached to the frame, and pulled by a handle 18 at the end of the platform 1.
It is something that attracts.

The tow bed of this invention allows you to simply rest on the platform and use your own weight to pull the column. Needless to say, it is also possible to connect a towing rope to the tow and use a weight or a motor for traction.

When placing a futon on the platform, use a futon that allows the divisions of the platform to expand and contract.

As described above, in the tow bed of the present invention, the platform is divided and at least one of the divided platforms is movably connected to the inclined frame, so that the bed can be held down on the platform. By simply moving the platform away from each other, the column is pulled, and this traction force becomes stronger as the patient weighs more, and is adjusted to a more ideal traction force according to the patient's weight. Furthermore, by pulling the pulling rope, the platform can be easily and easily pulled while lying down on the platform, allowing you to raise your upper body or hold the frame and lift your body as you did in the past. There is no need to lift it, and the platform is pulled while in the towing position.
This allows for towing in ideal conditions.
