One:

Patient beds are mostly multifunctional beds placed in the inpatient room, and these beds have the upper head to support the back while the patient is already lying or sitting on the bed, or the lower toe to raise the uncomfortable legs or food. Multifunctional beds come with an auxiliary table when ingested. In addition, the conventional bed and upper and lower movable bed structure for the examination of the hospital is mostly X-shaped height adjustment structure, such a structure is a risk factor that can hurt the user's finger or clothing when the operation or damage the clothing It is inherent. Therefore, the present invention has been devised as a structure that can remove these risk factors and operate more safely and stably than conventional methods.

In order to achieve the object of the present invention, the Shanghai-dong device uses a reduction motor, a worm gear, a bevel gear, an air shock absorber, and a screw to lift or lower the user's finger or clothing while being injured or damaged. The existing structure is increased as the upper part of the bed moves to the left or the right side with the ascension, and the installation area is widened. However, the device of the present invention has the structure that can be ascended and descended vertically. It has the advantage of being used as it is. It is possible to control the rotational direction of the reduction geared motor to raise or lower the bed.It can be operated simply by pressing the up / down adjustment button attached to the bed by the patient himself or by installing a foot switch on the floor. He also added the ability to hold the patient securely on the bed and then to hold the patient up and down as the feet move.

It is very difficult for a patient who is inconvenient to move up to a high bed with his own power, and the doctor, nurse or carer who is in charge of medical care must assist one or more patients. The bed proposed in the present invention is very inconvenient to lie down on a high bed fixed in height by the power of the patient alone, when the patient who visits the hospital or acupuncture hospital has to lie down on the examination bed. By devising a bed that is free to move up and down, the decelerated geared motor is a means for allowing the patient who is inconvenient to move up and down on the bed with the knee low as early as possible to adjust it to the desired height with the simple up / down button operation. When the worm gear set (3) connected to (2) rotates, the hexagonal aluminum metal shaft (4) connected to the left and right ends of the bed rotates and the rotational force is transmitted again through the left and right bevel gear sets (5). By turning the screws (6) on both left and right sides, the bed height is raised and lowered. Since the current fits to bear the weight of heavy patients only rotational force was such that the rise and fall action than a desired proceed by mounting the air shock absorbers (7) to a secondary load reinforcement device of the screw on the left and right side. This was solved by switching the rotational direction of the reduction geared motor in order to move up and down. The left and right lift frames 9 and 12 were firmly bolted onto a steel pedestal 13 using an aluminum profile to reduce bed weight. In order to increase the mechanical strength, the auxiliary aluminum support bar 15 is mounted across the left and right frame bodies for structurally high safety, and a non-slip buffer material 14 made of urethane rubber is placed on the bottom of the stand to increase friction with the floor. It was installed so that the bed would not slip when the patient moved up and down. The patient can operate the up and down buttons (7) on the bed by himself or herself, and the foot switch (8) is provided for interlocking with these buttons. It is designed to raise and lower the bed by foot movement while holding by hand. The bed top 10 material of the present invention is designed to provide a cushion by putting artificial cotton inside to the outer fabric made of natural leather, artificial leather, leisure and nonwoven fabric, and the combination with the top plate is long horizontally across the upper left and right support legs. It is adapted to be bolted to the attached steel bar 14.

By using the device of the present invention, it provides convenience for the patient who is inconvenient to move up to the examination bed, and maximizes the simplicity of operation by providing the height of the bed to use the hand of the patient himself or the foot motion of the people around him. It is equipped with deceleration geared motor, worm gear, bevel gear, and air shock absorber during ascending and descending operation so that anyone can easily lie the patient in the examination bed with no fear of movement when the patient moves up and down with smooth operation and stable operation. It works.

Claims (2)

The patient's lifting bed is a patient lifting bed that uses the reduction gear and motor, worm gear, bevel gear, air shock absorber and screw to soften the rising and falling height. Up and down height adjustable patient lifting bed device designed to help The bed top plate in the paragraph 1 is the upper and lower height adjustable patient lifting bed device to provide comfort by putting the artificial cotton inside the cushion made of natural leather, artificial leather, leisure and non-woven outer fabric to provide comfort
