Description

Bed for bedsore prevention}

The present invention relates to a bed for preventing bedsores, and more particularly, a bed for preventing bedsores that help prevent pressure sores by changing a subject's posture or enabling movement, thereby preventing continuous pressure from being applied to a specific part of the body. is about

Patients with reduced mobility spend most of their time lying in bed, and one of the most common diseases in these patients is bedsores.

Pressure sores, also called pressure ulcers, are a disease in which continuous or repeated pressure is applied to the protrusion of the bone, resulting in thrombus formation in blood vessels due to impaired blood circulation and necrosis of the tissue closest to the bone.

To prevent pressure sores, you should observe the area of pressure well and relieve the pressure. There are ways to change your posture every 1 to 2 hours or use a water bed or a cushion made of fur.

However, since these pressure sores frequently occur in unconscious patients, patients with cranial or spinal nerve damage, critically ill patients, etc., it is difficult to change posture or relieve pressure at will.

In addition, skin diseases such as bedsores frequently occur in the excretion of urine and feces. For this purpose, good ventilation is required to keep the skin dry.

In order to solve this problem, as prior art 1, Korean Patent Registration No. 10-1546345 (a device for preventing pressure ulcers) is described.

Korea Patent No. 10-1546345 (bedsore prevention device) consists of a fixing bracket, support rod, pulley, cable clamp, winch module, cable, and controller. It has the advantage of being able to easily change the patient's posture by moving it, but since a plurality of cables are combined at the end of the seat, one or more drivers who can assist the subject's posture are needed, or if there is no driver, a fall that separates from the seat It is possible to change the position, but there is a disadvantage in that the movement of the subject in the bed is not free.

It may be composed of a unit 113 and a fourth elevating unit 114 .

In this case, the height of the first lifting unit 111 and the second lifting unit 112 and the third lifting unit 113 and the fourth lifting unit 114 may be formed to have the same height, and the height can be adjusted as necessary. It can be formed to be possible.

The support pipe 200 is horizontally fixed to the upper end of the line actuator 100 .

In this case, the support pipe 200 may include a first support pipe 210 and a second support pipe 220 .

One end of the first support pipe 210 is coupled to the upper end of the first elevating unit 111, and the other end is coupled to the upper end of the second elevating unit 112 to form a first elevating unit 111 and a second elevating unit ( 112) as a form of connecting the upper end may be arranged horizontally.

In addition, one end of the second support pipe 220 is coupled to the upper end of the third elevating unit 113 , and the other end is coupled to the upper end of the fourth elevating unit 114 , and the third elevating unit 113 and the fourth elevating unit 114 . It may be arranged horizontally in the form of connecting the upper end of the part 114 .

At this time, the first support pipe 210 and the second support pipe 220 are preferably arranged in parallel.

The driving module 300 includes a first driving module 310 disposed on the left side of the bed 10 in the longitudinal direction and a second driving module 320 disposed on the right side of the bed 10 in the longitudinal direction.

The first driving module 310 and the second driving module 320 may each include a roll pipe 301 , a motor 302 , a reduction gear 303 , and a control unit 304 .

The motor 302 and the reduction gear 303 may be formed to wind or unwind the sheet 500 by rotating the roll pipe 301 in one direction or the other.

At this time, the roll pipe 301 is arranged horizontally on the side of the bed 10 in the longitudinal direction, and is fixed at a predetermined distance away from the bed 10 so that the sheet 500 can be wound and unwound while rotating. It is preferable to be

Accordingly, a fixing portion capable of fixing the roll pipe 301 to be spaced apart from the bed 10 may be provided separately.

The motor 302 drives the roll pipe 301 to rotate, and the reduction gear 303 may be formed to control the driving of the motor 302 .

The controller 400 may operate and control the driving of the line actuator 100 and the driving module 300 .

The controller 400 may include a control unit (not shown) for applying a control signal to the line actuator 100 and the driving module 300, and the line actuator 100 is driven according to the applied control signal to drive the lifting unit ( 100) may be raised or lowered, or the roll pipe 301 may be rotated to allow the sheet 500 to be wound or unwound.

In this case, the controller 400 may be configured to be operable by wire and wirelessly.

The sheet 500 has one end wound around the first drive module 310 and the other end wound around the second drive module 320 across the upper surface of the bed 10 through the upper end of the support pipe 200 . are placed

At this time, since the line actuator 100 is driven and the upper end of the lifting unit 110 is disposed higher than the height of the mat unit, the support pipe 200 may be disposed above the mat unit.

Accordingly, when the sheet 500 is wound or unwound by the driving module 300 , the sheet 500 is draped over the support pipe 200 , so that the sheet 500 may be inclinedly placed on the top of the mat part.

In addition, the tension of the seat 500 may be adjusted by controlling the rotation directions of the first driving module 310 and the second driving module 320 through the controller 400 .

In addition, the direction in which the sheet 500 is wound on the roll pipe 301 may be variable, and the driving direction of the roll pipe 301 may be changed according to the winding direction of the sheet 500 .

Figure 5 is a front view showing an example of the use of the present invention bed for preventing bedsores.

Referring to FIG. 5-(a) as an embodiment, when the first driving module 310 and the second driving module 320 rotate in the left direction, the sheet 500 is wound around the first driving module 310 and , the sheet 500 is unwound from the second driving module 320 to move the sheet 500 to the left.

At this time, as shown in FIG. 5-( b ), the subject M seated in a state lying on the seat 500 moves to the left together, and the seat by the first support pipe 210 disposed on the left By tilting the 500, the posture of the lying subject M is arranged obliquely, so that the posture of the subject M can be easily changed.

At this time, the sheet 500 is wound from the outside to the inside of the drive module 300 so that the rotation directions of the first drive module 310 and the second drive module 320 are the same, and the sheet 500 is wound in the winding direction. Accordingly, the rotation directions of the first driving module 310 and the second driving module 320 may vary.
