That is, the third hinge joint 50 folds and unfolds the second support frame 22 and the third support frame 23 at the same time as shown in FIG. 3 when turning the patient lying on the mattress to the side. As shown in Figure 4, the first support frame 21 and the fourth support frame 24 are attached in parallel with the first hinge joint 30 in a straight line so that simultaneous folding and unfolding operations are possible and smooth.

Here, the mattress is a multi-stage folding mattress that folds or unfolds according to the operation of the first to fourth support frames (21) (22) (23) (24), or a sponge mattress whose shape is flexible and elastically deformed by external pressure. can be employed.

Meanwhile, as shown in FIGS. 5 and 7, as the actuator A is driven, the first support frame 21 and the fourth support frame 24 or the second support frame 22 and the third support frame ( The angle of the support frame (20) can be adjusted by folding and unfolding 23) at the same time.

Here, the actuator (A) may be a pneumatic rodless cylinder in which the rod moves forward and backward using the magnetic force of a permanent magnet and pneumatic pressure.

In addition, a hydraulic or pneumatic solenoid valve that changes the direction of movement with the force applied from a hydraulic (pneumatic) pump can be adopted and applied.

For example, a hydraulic cylinder can be employed in which hydraulic pressure acts on both sides of the piston, producing output in both expansion and contraction.

In addition, the actuator (A) is a typical hydraulic motor that moves forward and backward or extends and contracts when a control unit such as a remote control transmits a control signal to a driving source such as a compressor to operate the cylinder (push loader, piston or plunger) with hydraulic or pneumatic pressure. When the electric motor is operated according to the opening and closing of the switch of the hydraulic cylinder or the control unit, it can be constructed as an electric cylinder (linear actuator) structure that converts rotary motion into linear motion and performs expansion and contraction.

For example, a linear reciprocating cylinder that uses two cylinders as a set, a linear motor that performs linear motion, a lead screw, etc., are engaged with a servo motor and a gear drive such as a rack and pinion to rotate the servo motor. Devices and actuator mechanisms that convert energy and control signals into mechanical work, such as a structure that converts motion into linear motion or a structure that controls the position by rotating a ball screw with a stepping motor using an encoder, can be adopted and applied.

Meanwhile, the control unit (not shown) may control the operation of the actuator (A) according to the switch opening/closing signal according to the operator's manual operation or the detection signal of each sensor.

The bed frame for preventing bedsores according to an embodiment of the present invention configured as described above has a virtual horizontal axis because the support frame 20 is divided into four parts and connected by first to third hinge joints 51, 52, and 53. Alternatively, it can be simply folded and unfolded manually or electrically in two areas at the same time based on the vertical axis.

Therefore, the patient lying on the mattress can be turned on his side or the patient can be reclined with the upper body raised at an angle.

For example, as shown in Figure 5, the actuator (A) is driven to move forward to move the first support frame 21 and the fourth support frame 24 or the second support frame 22 and the third support frame ( 23) at the same time by rotating it around the axes of the first hinge joint 51 and the third hinge joint 53 and folding it upright, so that the patient lying on the mattress can be easily and easily turned to the side.

In addition, as shown in FIG. 7, the actuator (A) is driven to move forward so that the first support frame 21 and the second support frame 23 are simultaneously rotated around the axis of the second hinge joint 40 and raised upward. By holding it or folding it at a certain angle, the upper body of the patient lying on the mattress can be raised at an angle and made to lean against the first support frame (21) and the second support frame (23), or the height of the upper body can be freely adjusted to a comfortable position.

In addition, a space and a ventilation hole 25 are opened between the support frame 10 and the support frame 20, so that air can be smoothly supplied and circulated to the patient's body parts in contact with the mattress at all times. .

Meanwhile, the present invention is not limited to the above-described embodiments and the accompanying drawings, and may be modified and applied in various ways not exemplified without departing from the technical spirit of the present invention. It is clear to those skilled in the art that the present invention can be broadly applied by replacing components and changing it to other equivalent embodiments.
