Description

TECHNICAL FIELD

The present invention relates to a functional table for patient transportation, and more particularly, to a functional table for patient transportation which is capable of transporting patients with safety, ease and promptness without a risk of secondary damage to the patients.

BACKGROUND ART

As known in the art, there has been proposed a variety of apparatuses for transporting emergency patients, critical patients, bone-fracture patients and the like, who are impossible or nearly impossible to move for themselves, from one place to another.

A patient in a hospital may be often moved from his/her hospital bed to a medical examination table or an operating table and vice versa. Primary equipment may include a stretcher carried by an assistant and a patient transporting bed with wheels.

However, there is a problem in moving the patient from the hospital bed to the stretcher or the patient transporting bed. For example, although it is a simple task to move the patient in support of the assistant if the patient is cooperative or can move for himself, there may be a challengeable task to move the patient from the hospital bed to the stretcher or the patient transporting bed if the patient is unconscious or has a damage such as a bone-fracture or an injury, which may be worsened by movement.

For the purpose of overcoming the above problem, a patient transporting apparatus is disclosed in, for example, Korean Patent Application Publication No. 2003-0073921.

The disclosed patient transporting apparatus is for transporting a patient who is laid on a stretcher placed on a carrier body. However, this has a problem in that it requires two assistants who have to lift the stretcher from its both sides when the patient is transported from one bed to another, and the weight of the stretcher to support the patient is still the same. In addition, a secondary damage may occur if the assistants miss the stretcher.

Moreover, there is a further problem that a patient who cannot be moved at all has to receive help from at least another assistant in order to transport and safely lay the patient on another table.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view illustrating a side of a functional table for patient transportation according to an embodiment of the present invention. As shown in FIG. 1, a functional table of the present invention includes a patient supporter to support a patient 100 (see FIG. 4), a vertically-movable support frame 20 to support the patient supporter 10, a base frame 30 which is connected to the bottom of the support frame 20 and supports the whole of functional table, and transporting wheels 40 which are connected to the bottom of the base frame 30 to allow the functional table to be freely moved in every direction.

In this manner, the functional table of the present invention is so configured that the patient supporter 10 on which the patient 10 is laid can be adjusted in its height by the vertically-movable support frame 20 connected to the central bottom of the patient supporter 10 as needed, and the functional table can be moved in every direction by the transporting wheels 40 connected to edges of the base frame 30 connected to the bottom of the support frame 20 to support the functional table.

Such a configuration allows the patient 100 to be transported to a medical examination table 200 (see FIG. 4) with more ease, convenience and safety without immoderate movement.

FIG. 2 is a view illustrating a front of the functional table for patient transportation according to an embodiment of the present invention. As shown in FIG. 2, the functional table has a structure in which the patient supporter 10 has two sides which are folded at a certain angle in a vertical direction in which the patient 100 is laid, with one of the two sides formed of two or more stages and with an upper portion of the one of the two sides being slidable in the vertical direction.

Such a structure allows for safe transportation of the patient 100 whose movement has to be minimized to prevent a backbone damage and so on when the patient 100 is transported to/out of the table.

This structure is differentiated from conventional simple sliding transportation structures in that the table can be vertically moved, with its both sides being inclined at a certain angle with respect to the patient 100 and with multi-staged one of the sides being slid in the vertical.

FIG. 3 is a front view showing an operation of the functional table for patient transportation according to the present invention. In more detail, FIG. 3 shows a change in an angle of the functional table in the vertical direction and a sliding structure. As shown in FIG. 3, the functional table has a structure in which the patient supporter 10 can be vertically moved by driving of the support frame 20 located in the lower center of the patient supporter 10 and can be inclined by changing its both sides by a certain angle, and an upper sliding supporter 13 can be slid by virtue of a two-staged structure of one of the sides.

Such a structure aims at safe and easy transportation of the patient 100 from the functional table to medical examination equipment such as CT, MRI and so on.

In other words, a traditional patient transportation table has a problem that a patient has to be moved by help of others from the patient transportation table to a medical examination equipment table since the former has a height different from that of the latter and a further safety problem that this process forces immoderate force or movement to be taken by the patient whose action or movement has to be minimized.

To overcome these problems, the patient transportation functional table of the present invention includes the support frame 20 to adjust the height of the patient supporter 10 to the height of the medical examination equipment table with ease and has a structure in which the sliding supporter 13 on which the patient 100 is laid can be slid from the patent transportation functional table to the medical examination equipment table for safe transportation of the patient 100 with minimized movement of the patient 100.

In addition, a support bar to prevent the patient 100 from being get out of the functional table is preferably provided in a side of the patient supporter 10. The support bar serves as a protection support as well as a grip grasped by the patient 100 who intends to be relaxed. This protective support bar is provided in both sides of the functional table and may include a railing sensor used to prevent the patient 100 from being get out of the table unconsciously. This railing sensor can sense movement of the patient 100 and generate an alarm or the like if the patient 100 is to get out of the functional table, thereby providing a safer functional table.

In addition, one side of the patient supporter 10 is formed of a multi-staged sliding driver which has guide rails formed in its both sides. In addition, preferably, a nonmagnetic roller connected to the guide rails is rolled in a horizontal direction. Alternatively, a multi-staged supporter may be employed as long as it can be slid.

In addition, preferably, the support frame includes a cylinder connected to the base frame 30 and a hydraulic actuator to actuate the cylinder vertically using a hydraulic pressure. As one example, although not shown, the hydraulic actuator may include an electric motor, a hydraulic pump driven by the electric motor for oil pumping, an oil tank connected to the hydraulic pump by a first connecting pipe for oil storage, and a second connecting pipe to connect the hydraulic pump and the cylinder so that oil can be fed from the hydraulic pump to the cylinder. Alternatively, although not shown, the hydraulic actuator may include an electric motor and a screw bar which is rotatably connected to the shaft of the electric motor and has threads screwed to the bottom of the support frame.

The patient transportation functional table of the present invention can be freely moved in every direction by the transporting wheels 40 provided in four bottom edges of the base frame 30. The transporting wheels 40 preferably include an electricity-free driving controller. This is because continued rotation and movement of the wheels 40 may generate static electricity due to friction with the ground, which may be delivered to the patient 100 or other medical equipment, thereby putting them in danger. Accordingly, it is advantageous to include a device which is able to prevent the static electricity from being introduced into the patient 100 and selectively automatically drive the wheels 40 and a driving controller to control the device.

A process of transporting the patient 100 from the patient transportation functional table to the medical examination equipment table and vice versa and effects thereof will be now described with reference to the relevant figures.

FIGS. 4 and 5 are views showing a process of transporting the patient 100 from the functional table to the medical examination equipment table. As shown in FIG. 4, the functional table on which the patient 100 is laid approaches the examination table and the support frame is driven to adjust the height of the functional table to the height of the examination table. Thereafter, one opposing side of the patient supporter 10 adjacent to the examination table is rotated and ascended such that it is inclined at a certain angle.

Then, the patient 100 can be slidably moved by the inclination according to the gravity in the opposite direction and, accordingly, can be horizontally naturally moved toward the examination table without significant movement. In this manner, the patient 100 can be naturally and safely moved by the functional table which is able to be rotated at a certain angle around the vertical axis of the patient 100.

FIG. 5 is a view showing an operation of transporting the patient 100 from the functional table to the examination table. As shown in FIG. 5, when the patient 100 is horizontally moved to the examination table by the table vertical axial rotation, a portion of the patient 100 who lies on the functional table is leaned toward the sliding supporter 13. As one side of the patient supporter 10 on which the patient 100 lies has a two-staged sliding structure, the patient 100 can be transported to the examination table with safety and convenience by sliding and moving the upper sliding supporter 13 to the examination table.

In this manner, according to the present invention, the patient 100 can be transported to the examination table only by actuation of the functional table with ease, safety and promptness without help of others.

FIGS. 6 to 9 are views showing a process of transporting the patient 100 from the examination table to the patient transportation functional table. As shown in FIG. 6, the patient 100 is again moved to the examination table after the patient 100 is examined in the examination table. With the patient 100 lying on the examination table, the functional table is moved to the examination table and is adjusted in height to the examination table by driving the support frame 20.

At the same height of the examination table and the functional table, the multi-staged sliding supporter 13 is slidably moved to support the patient 100 at one side of the functional table adjacent to the examination table.

Then, referring to FIG. 7, in order to again move the patient 100 to the functional table, instead of horizontally moving the sliding supporter at the same height, when the support frame 20 of the functional table is descended to lower the functional table, one side of the patient supporter 10 supporting the sliding supporter is leaned at a certain angle so that the sliding supporter 13 can be horizontally naturally moved to the functional table by the gravity, as shown in FIG. 7.

Once the support frame of the functional table is descended to make a tilt angle and the patient 100 is slidably moved with the sliding supporter 13 by the tilt, the patient 100 can be placed in the central portion of the functional table with safety and promptness when the support frame 20 is again ascended, as shown in FIG. 8.

Then, finally, as shown in FIG. 9, by moving the sliding supporter 13 to its original position and ascending and stopping the support frame to its original position, the patient 100 can be transported from the examination table to the patient transportation functional table with ease, safety and promptness.

Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that adaptations and changes may be made in these exemplary embodiments without departing from the spirit and scope of the invention, the scope of which is defined in the appended claims and their equivalents.
