Description

{BED FOR PREVENTING DECIBITUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bed for preventing bedsore, and more particularly to a bed for preventing bedsore in which an actuator is installed in bed.

A benign disease is benign disease in unconscious patients, patients with neurological or spinal cord injuries, elderly patients, patients with chronic illnesses, patients with chronic debility, and patients living in bed.

In these patients, since the same posture is maintained for a long time, the blood circulation and metabolism are not smoothly performed, so that a pressure ulcer is likely to occur in a region to be pressed.

In order to prevent pressure ulcer, it is necessary to change the posture of the patient every time to relieve the burden of the compression area. However, since all the patients can not keep moving with the help of a caregiver or other person, it is a mat and bed to prevent pressure ulcers.

However, even if it is a mat and a bed for preventing a pressure ulcer, if a patient lie or sit for a long time, a local excessive pressure is constantly or repeatedly applied to the floor, such as the back or the hip area, and the occlusion of the capillary blood vessel is continued. So that a pressure ulcer occurs.

In the formation of the pressure ulcers, the pressure acting on the lesion site and the time of the action of the pressure are influenced. In the beginning, the skin is not damaged but it is discolored. As it progresses, In severe cases, subcutaneous fat layer or even muscle and bone tissue may be damaged.

Also, in such cases, the patient experiences great pain and lowers the quality of life, and once the pressure ulcer occurs, the recovery rate is slow due to the characteristics of the patients who are uncomfortable to move. In the case of the elderly whose physical healing ability is poor, The recovery is difficult and the wounds are easily worsened, which can lead to the economic loss as well as the death of the patient and the social loss is very large.

In recent years, the electric bed 10 has been introduced more and more in order to receive even a little help from such inconvenience.

1 is an operational state view of a conventional electric bed.

As shown in FIG. 1, the electric bed 10 is an electric bed, in which an angle of a portion 12 supporting a back of a human body and a portion 14 supporting a leg in a support surface for supporting a patient is electrically controlled, So that the patient can be more easily cared for.

However, in order to prevent the occurrence of a pressure ulcer in a patient lying on the electric bed, the angle of the supporting surface may be changed at regular intervals to change the posture of the patient. Since it is not optimized according to individual characteristics and is uniformly applied, it can not provide optimized posture conversion cycle for each individual patient, and it does not take into consideration the characteristics of each body part, so the patient must move the upper body or lower body as a whole There is a problem.

It is an object of the present invention to provide a bed for preventing a pressure ulcer, and more particularly, to provide a bed for preventing a ulcer, in which concentrated management of a body part having a high risk of bed ulcers is possible.

Here, the plate may be a plate-like shape having a curvature in an upward direction.

Here, the controller may determine the height displacement value of the plate corresponding to the upper portion of the pressure sensor based on the sensing value, and may control the actuator with the determined height displacement value.

Here, the actuator may be a pneumatic cylinder, a hydraulic cylinder, or an electric motor.

The bed for preventing bedsores according to the embodiment of the present invention can manage the risk of bedsore occurrence regardless of the body size or posture of the user. Further, the user can recognize the changed posture without any additional operation, and the body is not subjected to an excessive impact.
