It describes the operating state of the multifunctional electric bed for hospital of the present invention configured as described above.

First, the operation state for adjusting the left and right inclination and the front and rear inclination of the first operation frame 20 using the inclination adjustment means 100 will be described.

First, in order to tilt the first operation frame 20 to the left or the right side, the controller operates a pair of left and right pairs of cylinders 120 and 130 fixed to the support frame 10 by the lower end.

Then, the cylinders 120 and 130 are hinged to the rotating plate 112 while the ends are coupled to the shafts 121 and 131 to the horizontal holes 114 formed at the left and right sides of the movable bracket 110, respectively. 113a) Since it is connected to the pair of connecting bars 113 coupled, for example, when the left cylinder 120 is operated, the left end of the movable bracket 110 is lifted and tilted to the right, and the right cylinder 130 When the) is operated, the right end of the movable bracket 110 is lifted and tilted to the left. The left and right ends of the movable bracket 110 are respectively provided on both the left and right sides of the first operation frame 20. Since the hinge 111 is coupled, the first operating frame 20 is inclined in the same direction as the inclined direction of the movable bracket 110.

On the other hand, when tilting the movable bracket 110 in order to tilt the first operation frame 20 to the left or right, for example, one cylinder 120 is still and only the other cylinder 130 is moved, so that the movable bracket 110 is horizontal. The distance between the two shafts 121 and 131 of the pair of cylinders 120 and 130 coupled to the long holes 114 is longer than when the movable bracket 110 is horizontal.

In the present invention, however, the pair of connecting bars 113 coupled to the hinge 113a to the rotating plate 112 while rotating the rotating plate 112 compensates for the difference between the axes between the two sides or the inside of the plate. The operation is smooth.

As such, when the first operation frame 20 is inclined to the left or right side, the second operation frame 30 is installed to be positioned above the first operation frame 20, and the second operation frame 30 is connected to the second operation frame 30. Since the bed top plate frame 40 is also inclined at the same time in the same direction as the inclination direction of the first operation frame 20, the body of the patient lying on the bed top plate frame 40 can also be inclined to the left or right of course.

This time, the operation state for adjusting the inclination before and after the first operation frame 20 by using the inclination control means 100 will be described.

First, in order to lift the front of the first operating frame 20 to the upper side by operating the controller to the horizontal hole 141 formed in the front and rear directions on the fixing bracket 140 behind the first operating frame 20 The tip is coupled to the shaft 151 and the lower end of the cylinder 150 fixed to the support frame 10 is left as it is, a pair of shafts 121 and 131 coupled to the horizontal hole 114 of the movable bracket 110 The cylinders 120 and 130 are operated at the same time to raise and lower the movable bracket 110.

Then, both ends of the movable bracket 110 are hinged 111 so as to be rotatable on both the left and right sides of the first operating frame 20, respectively, so that the front of the first operating frame 20 has a front end of the cylinder 150. It is lifted upwards about the axis 151.

On the contrary, when the rear of the first operation frame 20 is to be lifted upward, the movable bracket 110 in which both ends of the left and right sides are hinged 111 in front of the first operation frame 20 by operating a controller. Leave the pair of cylinders 120 and 130 coupled to the shaft 121, 131 to the horizontal long hole 114 of (), in the front and rear directions to the fixing bracket 140 behind the first operating frame 20 The front end is coupled to the formed horizontal long hole 141, the shaft 151 and the lower end operates the cylinder 150 fixed to the support frame 10.

Then, the rear of the first operation frame 20 is lifted upward by the cylinder 150 with respect to the hinge 111 of the movable bracket 110.

As such, when the first operation frame 20 is tilted forward or backward, the second operation frame 30 connected to the first operation frame 20 and installed on the upper side of the first operation frame 20 is connected to the second operation frame 30. Since the bed top plate frame 40 is also inclined at the same time in the same direction as the inclination direction of the first operation frame 20, the body of the patient lying on the bed top plate frame 40 can also be inclined forward or backward naturally.

Next, the operation state for rotating the second operation frame 30 to the left or right by 90 ° angle using the rotation control means 200 will be described.

First, in order to rotate the second operation frame 30 to the left and right, the controller 230 is operated by operating a hydraulic or electric actuator 230 having a rear end coupled to the first operation frame 20 by a hinge 232. Rotating the rotary lever 220, the hinge 231 is coupled to the tip.

Then, the rear end of the rotary lever 220 is coupled to the input shaft 211 of the reducer 210, so as the input shaft 211 is rotated and the rotational speed and rotational force are decelerated and increased to be transmitted to the output shaft 212 and output shaft 212. The second operating frame 30 fixed to the upper surface of the rotating plate 213 coupled to the) rotates to the left or right at an angle of 90 °.

At this time, the rotation direction determination of whether to rotate the second operation frame 30 to the left or right is configured to rotate the rotary lever 220 coupled to the input shaft 211 of the reducer 210 to the left. Or it is configured to rotate to the right side in the present invention because the front end of the rotary lever 220 is formed to be divided into the V-type according to the installation location of the electric bed according to the present invention, the left end (220a) or It is very convenient to use because it can be selected from the right end (220b) to hinge the front end of the actuator 230 to determine the rotation direction.

As such, when the second operation frame 30 is rotated 90 degrees to the left or the right, the bed top frame 40 connected to the second operation frame 30 is also rotated in the second operation frame 30. Since the same direction is rotated at the same time and the body of the patient lying on the bed top frame 40 is also naturally rotated to the left or right by 90 ° angle.

On the other hand, when the second operation frame 30 and the bed upper frame 40 to rotate at the same time to the left or right by 90 ° angle both sides of the front and rear bed upper frame 40 is the first operating frame ( 20) may cause interference by contacting the safety plate 21 vertically installed at both front and rear ends of the front and rear sides of the bed upper plate frame 40 which is connected to the second operation frame 30. Make it folded and then rotate it.

Therefore, hereinafter, the operating state of the bed upper plate frame 40 connected to the second operation frame 30 will be described in detail.

Then, the tip of the upper support plate 42 coupled to the tip of the cylinder 42b around the hinge 42a is folded while lifting or lowering.

On the other hand, in order to fold the thigh support plate 43 to operate the controller to operate the cylinder 43b connected to the butt support plate 41.

Then, the rear end of the thigh support plate 43 coupled to the front end of the cylinder 43b around the hinge 43a is folded while lifting or lowering.

Meanwhile, in order to fold the calf support plate 44 coupled to the thigh support plate 43 and the hinge 44a, a cylinder 44b connected to the thigh support plate 43 is operated using a controller.

Then, the rear end of the calf support plate 44 coupled to the tip of the cylinder 44b around the hinge 44a is folded while being lifted or lowered, at this time, by the folding angle of the thigh support plate 43 and the calf support plate 44. The bending angle of is adjusted.

Using the electric bed of the present invention with the various functions as described above, for example, the tilt adjusting means 100 is set to operate at an interval of 30 minutes so that the left and right tilts before and after the first and second operating frames 20 are tilted. When the control is provided, the second operation frame 30 is installed to be located above the first operation frame 20, and the bed upper plate frame 40 connected to the second operation frame 30 is also the first operation Since the inclination of the frame 20 is inclined at the same time at the same time, the body of the patient lying on the bed top frame 40 is also naturally left, right, and forward and backward while body pressure is dispersed, so that blood circulation is smooth and prevention of pressure sores. .

On the other hand, the patient lying on the electric bed while operating the upper body support plate 42, thigh support plate 43, calf support plate 44 constituting the tilt control means 100 and the bed top frame 40, in particular By making it possible for the critically ill patient who is uncomfortable to take a variety of postures, it is possible to remove the sputum in the lungs with less effort. (The configuration and operation of the tilt control means 100 and the bed top frame 40 Since the configuration and operation have already been described above, detailed operation states are omitted.)

That is, the sputum discharge can be facilitated by executing various operation modes.

Meanwhile, the electric bed of the present invention operates the upper body support plate 42, the thigh support plate 43, and the calf support plate 44 constituting the rotation control means 200 and the bed top frame 40 in combination with the patient. The chair can be easily transferred to a chair.

That is, when the controller is operated in the seating mode, for example, after the upper support plate 42 and the thigh support plate 43 constituting the bed upper frame 40 are raised (see FIG. 10), the bed upper frame 40 is connected. After the installed first operating frame 20 is rotated by the rotation control means 200 and the second operating frame 30 by 90 degrees (see Fig. 11), the thigh support plate 43 is lowered horizontally and at the same time The calf support plate 44 is lowered to be in a right angle, as well as the upper support plate 42 ascends as much as possible (see FIG. 12).
