In the medical bed provided with an insertion groove forming function for lifting a patient, the first and second embodiments according to the specific structure of the insertion groove forming part 400 will be described.

The first embodiment of the insertion groove forming unit 400 may include a track roller 410 and a return coil spring 420, as shown in FIGS. 2 to 4, so that the track roller 410 can slide and move. In the fixed mattress 200, a linear moving groove 220 and an inclined moving groove 230 are recessed.

That is, the fixed mattress 200 extends from the linear moving groove 220 and the linear moving groove 220 which are recessed in each of the insertion grooves 210 facing each other with the front and rear sides of the lifting mattress 300 to the left. The inclined moving groove 230 is formed to be inclined downward in the direction and is provided in a pair of left and right, respectively. At this time, each of the insertion groove forming parts 400 includes a track roller 410 and a return coil spring 420, and the track roller 410 is the linear moving groove 220 and the inclined movement of the fixed mattress 200. It is coupled to the front and rear sides of the lifting mattress 300 so as to be slidable along the groove 230.

Accordingly, as shown in FIGS. 3 and 4, when an external force acts from the right direction of the lifting mattress 300, the track roller 410 coupled to the lifting mattress 300 slides along the linear moving groove 220 to the left. It moves in a straight line with the elevating mattress 300 in the direction, and moves downward with the elevating mattress 300 toward the lower left along the inclined moving groove 230. That is, as shown in Figure 5, when a caregiver or medical staff pushes an insert member such as an arm or a transfer device from the right direction of the lifting mattress 300, the lifting mattress 300 operates to move linearly in the left direction and downward. And, as shown in Fig. 6, it is possible to easily lift the patient upward.

After lifting the patient upward in this way, the external force is released, and the elevating mattress 300 returns as shown in FIG. 1, which is achieved through the return coil spring 420. That is, the return coil spring 420 is installed between the frame 120 of the bed body 100 and the elevating mattress 300 so that the elevating mattress 300 is an insertion groove 210 of the fixed mattress 200 It provides a spring force to seal it. Although the return coil spring 420 is largely shown as one in the drawing, a pair or a plurality of more than one may be provided.

Meanwhile, the second embodiment of the insertion groove forming unit 400 is a moving link 430, a first rotating link 440, a second rotating link 450, a moving transmission link as shown in FIGS. 7 to 9 460), a spring force transmission link 470 and a return torsion spring 480 may be included.

The moving link 430 is fixedly coupled to the lower portion of the elevating mattress 300 to move together with the elevating mattress 300. That is, according to the movement of the moving link 430, each link to be described later rotates.

One end of the first rotation link 440 is rotatably coupled to the right side of the moving link 430 and the other end is rotatably coupled to the frame 120 of the bed body 100. That is, the frame 120 becomes a fixed reference as a base link, and the moving link 430 moves based on the fixed frame 120, and the first rotation link 440 is It will rotate.

The second rotation link 450 has the same length as the first rotation link 440 and forms a parallel crank mechanism together with the first rotation link 440, and one end is rotatable to the left of the moving link 430 And the other end is rotatably coupled to the frame 120 of the bed body 100. That is, as shown in Figs. 8 and 9, the second rotation link 450 forms a parallel crank mechanism together with the first rotation link 440, so the moving link 430 is always framed together with the lifting mattress 300 ( 120) will move in a parallel state.

The movement transmission link 460 has one end rotatably coupled to the left end of the movable link 430, and the spring force transmission link 470 has one end rotatably coupled to the other end of the movable transmission link 460 , The other end is rotatably coupled to the frame 120 of the bed body 100. At this time, a return torsion spring 480 is installed at the other end of the spring force transmission link 470, and the return torsion spring 480 seals the insertion groove 210 of the fixed mattress 200 with the lifting mattress 300 A spring force is provided to the spring force transmission link 470 so as to be performed.

That is, as shown in FIG. 9, when an external force acts from the right direction of the lifting mattress 300, the lifting mattress 300 moves linearly and downward in the left direction, and along with the movement of the lifting mattress 300 in the left direction The moving link 430 also moves to the left. At this time, the moving link 430 is moved in a parallel state with respect to the frame 120 by the first rotation link 440 and the second rotation link 450, and the spring force while the movement transmission link 460 rotates. The transmission link 470 is rotated, and the return torsion spring 480 is compressed according to the rotation of the spring force transmission link 470 to accumulate spring force. After that, when the external force is released from the right direction of the lifting mattress 300, the spring force transmission link 470 is rotated and restored by the spring force of the return torsion spring 480 as shown in FIG. 8, and the moving transmission link 460 ) It is to return the elevating mattress 300 to the right side with the moving link 430 while also returning to rotation.

In addition, each of the insertion groove forming parts 400, when the lifting mattress 300 seals the insertion groove 210 of the fixed mattress 200, the first rotation link 440 and the second rotation link ( 450) is located inclined to the right. This is different from the insertion groove forming part 400 maintaining the closed state of the lifting mattress 300 by the linear moving groove 220 in the track roller 410 structure of FIGS. 2 to 4, as shown in FIG. This is because it is necessary to maintain the sealed state by supporting the lower right of the lifting mattress 300 by the right end sealing member 500.

At this time, as shown in FIG. 8, when the patient is lying down and pressure is applied from the upper side, if the first rotation link 440 and the second rotation link 450 are inclined to the left, the moving link 430 is arbitrarily moved to the left. Since the first rotation link 440 and the second rotation link 450 must be positioned to be inclined in the right direction, the lower right of the lifting mattress 300 is in the right end sealing member 500 because it can be moved linearly and downward. Since it is supported by the airtight structure of the lifting mattress 300 is maintained.

As described above, the medical bed equipped with an insertion groove forming function for lifting the patient according to the present invention can be moved by magnetic force through the insertion groove forming part 400 together with the fixed mattress 200 and the elevating mattress 300. There is an effect of minimizing the discomfort of the patient when a caregiver or medical staff wants to lift and move it through an arm or a transfer device while providing a comfortable bed to a patient who does not have it.

In particular, the structure of the insertion groove forming unit 400 is a structure of a track roller 410 that slides along a linear moving groove 220 and an inclined moving groove 230 or a moving transmission link 460 and a spring together with a parallel crank mechanism. There is an effect of having a simple structure at low cost through the structure of the power transmission link 470.
