Description

The equipment prevent dedsore both sides decline.

The present invention is an electric auxiliary device for preventing bedsores in critically ill patients, and the device is in the form of one unit or module and can be attached and detached from the bed, so that it can be applied to the existing bed as it is, and a set control method (operated by a controller) Control, time control, height adjustment, and alternating timing settings for left and right placement) not only can effectively provide the patient's bed sore prevention, but also allow the patient's posture to be continuously changed through an electric motor.This is a bar that does not require a caregiver or guardian. It relates to an electric bed sore prevention device detachable to the bed, characterized in that the periodic bed sore prevention management can be performed.

In general, bedsores (褥瘡, Decubitus) refers to a skin injury caused by contacting the back, waist, shoulders, and elbows of a patient lying on a bed for a long time.

These symptoms of bedsores can be seen in patients who have been debilitated in bed for a long time or in patients who cannot freely change their position due to a disorder of the cerebrospinal nerve. It can also be caused by pressure from the cast.

The skin on the pressed part becomes pale at first because the blood circulation deteriorates, and the area around it becomes red, causing tenderness.

It is one of the very dangerous diseases in which blisters (blisters) are formed later, and the part that caused gangrene (壞疽) is eliminated and odorous secretions are released by forming ulcers.

Another bed for preventing bedsores is disclosed in Korean Patent Application Publication No. 10-2001-0001177 (published on January 5, 2001).

The bed disclosed in the above patent data raises and lowers a separate mesh-type hoisting frame by an automatic or semi-automatic lifting means by a periodic operation means such as a timer to prevent pressure sores that are likely to occur in patients who have to lie on the bed for a long period of time. It has a structure in which air is blown between the mattress and the patient's body to dry by blowing air and sterilize by emitting ions and ultraviolet rays while preventing bedsores of the patient by ventilation.

In addition, another bed for preventing bedsores is disclosed in Korean Patent Laid-Open Publication No. 10-2003-0020162 (published on March 8, 2003).

The bed for preventing bedsores and its lifting method disclosed in the above patent data is that the flat plate and the uneven plate constituting the upper plate of the bed are alternately lifted and lowered, so that the horizontal state is partially maintained in the ascending state, and at the same time, one of the lowering and raising motions is performed. Since the other is configured to maintain a certain horizontal state even during the period, the flat plate and the uneven plate are raised and lowered without being detected by the patient or the bed user, allowing ventilation and smooth blood circulation to the pressure area of the body. Has been.

However, the bed as described above has a problem in that it is less feasible because a high manufacturing cost occurs in implementing a structure in which an uneven plate or the like is alternately lifted and lowered.

In addition, the beds as described above have improved the occurrence of bedsores to some extent by ventilating air or sterilizing ions and ultraviolet rays, or improving ventilation and blood circulation to the body pressure area, but the cushioning feeling is bad and the resistance is significantly reduced. There is a problem that it does not have a great effect on the elderly with symptoms of bedsores, as it is only to the extent of delaying bedsores when used for the elderly who have been used, and it does not function to actively remove the factors that cause bedsores.

Moreover, the problem of insufficient pressure due to the normal bed being covered with a blanket, and when the user wakes up in the bed, air continuously blows out through the exhaust hole, causing strain on the motor or weakening the pressure, making it difficult to achieve the intended purpose. There is a problem that it is difficult.

The present invention is to solve the above-described problem, and the technical gist of the present invention is an electric auxiliary device for preventing bedsores in critically ill patients, and the device is in the form of one unit or module and can be attached and detached to the bed, so that it can be applied to the existing bed It has the advantage of being able to effectively prevent bedsores of the patient by the set control method (motion control by a controller, time control, height adjustment, alternating timing setting for left and right placement, etc.), as well as the ability to continuously maintain the patient's posture by motorized operation. The purpose of this is to provide an electric bedsore prevention device detachable to a bed, characterized in that periodic bedsore prevention management can be performed without a caregiver or guardian.

In order to achieve this object, the present invention has a link arm 120 that is elevating and descending based on the support 110, and an actuator in which a first hinge hole 130 is formed at one side of the link arm 120 ( 100) and; A rail 210 is formed to slide in a direction orthogonal to the actuator 100, and a guide block 220 capable of reciprocating in a longitudinal direction on the line of the rail 210 has a second hinge hole 230 A linear guide 200 formed to have; A hinge bracket 310 is formed to correspond to the first hinge hole 130 of the actuator and the second hinge hole 230 of the linear guide, and the hinge bracket 310

An angle adjustment plate 300 on which an up-down plate 320 is formed to lift the affected part of the patient to prevent pressure sores; It is composed and made.

At this time, it is preferable that the link arm 120 of the actuator is an articulated link arm that can be rotated by one or more hinge shafts (140) in the vertical direction.

In addition, the hinge shaft 140 is preferably provided with a stopper 150 to adjust the rotation angle on one side.

Accordingly, it is preferable that the angle adjustment plate 300 has a non-slip dot or Velcro pad 321 formed on the upper surface of the up-down plate 320 so as to improve adhesion to the bottom surface of the bed mattress.

In addition, it is preferable that the bed sore prevention device is disposed on both sides so as to face each other based on the central part of the bed so that the patient's body can be turned left and right.

As described above, the present invention is an electric auxiliary device for preventing bedsores in critically ill patients, and the device is in the form of one unit or module and can be attached and detached to the bed, so that it can be applied to the existing bed as it is, and the set control method (controller It is possible to effectively prevent bedsores by using motion control, time control, height adjustment, and alternating timing setting for left and right arrangements), as well as allowing the patient to continuously change the patient's posture with an electric motor. It has the effect of allowing periodic bedsore prevention management to be performed without a child or a guardian.
