Pressure sores prevention bed with adjustable head rest wherein a patient's body remains in the same position

Abstract

The pressure sores prevention bed according to this invention consists of two parts arranged in an alternated fashion. Parts A (1) and Parts B (2) are moved upward and downward by the lifting sets C (3), M (10), and F (6), N (11). While Parts A (1) are at the lowered position, Parts B (2) support the patient's entire weight, and the patient's skin does not touch Parts A (1). While Parts B (2) are at the lowered position, Parts A (1) support the patient's entire weight, and the patient's skin does not touch Parts B (2). The lifting sets C (3) and F (6) are controlled by the control set D (4) which has a timing switch which can be set for a period of 1-30 minutes, with a circuit breaking system provided. The pressure sores prevention bed according to this invention also includes the system for inclining the head end of the bed and the system for tilting the head rest at the angle of 10-15°.

Description

OBJECTIVE OF THE INVENTION [0001] The pressure sores prevention bed according to this invention consists of two parts, A (1) and B (2). Both parts are operated to move the bed upward and downward at the predetermined time by using a timer. The movements of the two parts result in the shifting of the patient's weight pressed against the bed. When Parts B moves downward below Parts A, the latter supports the patient's entire weight, and when Parts A moves downward below Parts B, the latter supports the patient's entire weight. The points where the weight is supported on Parts A and B are different depending on the cushion arrangements (in the xylophone track pattern or the chess pattern). The shifting of the weight supporting points allows the patient's skin and muscles to be relaxed. The appropriate time interval for each shifting is no more than 30 minutes. In addition, the head end of the bed can be inclined, and the head rest can be tilted at the angle of 10-15° with respect to th...

The movements of the two parts result in the shifting of the patient's weight pressed against the bed. When Parts B moves downward below Parts A, the latter supports the patient's entire weight, and when Parts A moves downward below Parts B, the latter supports the patient's entire weight. The points where the weight is supported on Parts A and B are different depending on the cushion arrangements (in the xylophone track pattern or the chess pattern). The shifting of the weight supporting points allows the patient's skin and muscles to be relaxed. The appropriate time interval for each shifting is no more than 30 minutes. In addition, the head end of the bed can be inclined, and the head rest can be tilted at the angle of 10-15° with respect to the bed structure. Such features are especially useful for treating broken neck patients with the need of using the weight balls. MAIN OBJECTIVE

[0002] It is the main objective of this invention to prevent a patient from pressure sores which normally occurs to the patients who have to stay in bed and cannot move their body due to any serious damage to their brain, spine, or the whole body. The position of these patients needs to be changed every 1-2 hours, otherwise the pressure sores will occur approximately within 2-3 days. However, with the use of this invention, the pressure sores occurrence can be prevented without changing the patient's position. FURTHER OBJECTIVE

[0003] Moreover, this invention helps reduce muscle ache, thus making the patient feel comfortable and recover more quickly after such operations as hip joint replacement, operations on the digestive system, operations on the cardiovascular system, or brain surgery. The inclinable head end also facilitates the process of administering food to the patient and the physical therapy. Since the head rest can also be tilted at the angle of 10-15° with respect to the bed structure, it is helpful for those patients who are under the treatment for broken neck. COMMERCIAL OBJECTIVE

[0004] The cost and time of the health care needed for the patient with pressure sores are high because the patient needs special care from the doctors and nurses at the hospital, and from the relatives after leaving the hospital. It is therefore the objective of this invention to reduce the time and money for both the hospital and the patient's relatives. In addition, the beds for the patient with pressure sores currently available on the market are not substantially efficient, and the efficient ones have to be imported from overseas at high price whereas the bed according to this invention is cheaper because the materials used are obtained domestically.
