Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only used as examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, an automatic turn-over bed comprises a bed frame 4 and an upper computer, and further comprises: the system comprises an information acquisition module, a headrest plate 1, a main beam 7, a secondary beam 5, a main body plate 3, a leg plate, a driving structure and a supporting beam 8. The headrest plate 1 is arranged at the head of the bed and is detachably connected with the bed frame 4. One end of the main beam 7 is fixedly connected with the bed tail of the bed frame 4, and the other end is fixedly connected with the headrest plate 1. The two ends of the auxiliary beam 5 are respectively fixedly connected with the two side plates 61 of the bedstead 4 and fixedly connected with the main beam 7, and the bedstead 4 is divided into four areas. The main body plate 3 is provided with two blocks which are respectively arranged in two areas between the secondary beam 5 and the headrest plate 1. Two leg plates are respectively arranged in two areas between the auxiliary beam 5 and the bed tail. The supporting beams 8 are arranged below the two sides of the bedstead 4, are fixedly connected with the bed legs and are parallel to the bedstead 4. And the information acquisition module is in communication connection with the upper computer and is used for acquiring the sleeping posture of the patient.

As shown in fig. 1 and 4, the driving mechanism is fixedly connected to the support beam 8 and electrically connected to the upper machine so as to abut against the lower surface of the main body plate 3 or the leg plate, and drives the main body plate 3 or the leg plate to rotate about the main beam 7. The driving structure includes: drive motor, slide rail 91, support structure 92 and screw 93. The driving motor is arranged on the bedstead 4 and is electrically connected with the upper computer. One end of the slide rail 91 is fixedly connected with the main beam 7, and the other end is fixedly connected with the support beam 8. The screw 93 is installed in the slide rail 91, one end of which is rotatably connected with the main beam 7, and the other end of which penetrates through the support structure 92 and the support beam 8, is driven by a driving motor, and is in threaded connection with the support structure 92, and is used for driving the support structure 92 to slide in the slide rail 91. Since the support beams 8 are positioned below the frame 4 and the main beams 7 are at the same level as the frame 4, the slide rails 91 connecting the main beams 7 and the support beams 8 are inclined. When the support structure 92 moves on the slide rails 91, it causes the body panel 3 or the leg panel to tilt or lift.

The support structure 92 is mounted in the slide rail 91 with one end abutting against the lower surface of the main plate body or the leg plate and the other end slidably connected to the slide rail 91. The support structure 92 includes: the slider 921, screw hole 922, rotation wheel 925, bracing piece 924 and connecting block 923. The slider 921 is mounted in the slide rail 91 and slidably connected to the slide rail 91. The threaded hole 922 is a through hole formed in the slider 921, and is provided with an internal thread to be engaged with the screw 93. The connecting block 923 is located above the sliding rail 91 and is fixedly connected with the sliding block 921. One end of the support rod 924 is fixedly connected with the connecting block 923. The rotating wheel 925 is rotatably mounted on the other end of the support lever 924, is rotatably connected to the support lever 924, and abuts against the lower surface of the main body panel 3 or the leg panel. Since the contact point between the top of the supporting structure 92 and the main body plate 3 and the central beam 62 is gradually shifted along with the rotation of the main body plate 3 and the central beam 62, the top of the supporting structure 92 and the main body plate 3 or the central beam 62 are finally jammed, and the turnover is difficult. Therefore, the rotating wheel 925 is used as a contact structure for force application, and the problem of blocking can be well avoided.

One side of the main body plate 3 is hinged with a main beam 7, and the other three sides respectively abut against the auxiliary beam 5, the headrest plate 1 and the bed frame 4. The lower surface of the main body plate 3 is provided with a first slide groove 31 parallel to the slide rail 91. The bottom surface of the first sliding groove 31 abuts against the rotating wheel 925 of the support structure 92.

The leg plates are hinged to the main beam 7. The leg plate includes: a center beam 62, side plates 61 and a flipping plate 63. The central beam 62 is disposed above the slide rail 91, parallel to the slide rail 91, and has one end slidably connected to the turnover plate 63 and the other end abutting against the frame 4. The two side plates 61 are respectively arranged on two sides of the central beam 62, one side is hinged with the central beam 62, the other side is connected with the rotating plate in a sliding way, and the other two sides are propped against the bedstead 4.

As shown in fig. 2, the turning plate 63 is mounted on the side of the main beam 7 and hinged to the main beam 7. The turning plate 63 is provided with a first trough 631, a second trough 633 and a slide hole 632. The first and

second tanks

631 and 633 are provided on one surface of the reversing plate 63 facing the side plate 61, and are used for sliding the side plate 61 on the reversing plate 63. The slide hole 632 is a through hole opened in the middle of the rotating plate for the center beam 62 to pass through. The first and

second tanks

631 and 633 are mesa tanks. The running track of the side plate 61 can be fixed, and meanwhile, the side plate 61 can be prevented from being limited when inclined.

The first sliding groove 31 and the second sliding groove 621 formed in the main body panel 3 and the center beam 62 can prevent a problem such as a side slip from occurring when the center beam 62 and the main body panel 3 are supported, and the like from affecting the turning operation, for a running rail to which the turning wheels 925 are fixed.

As shown in fig. 3, the center beam 62 includes: a sliding block 622, a main block body, a stopper 623, and a second sliding groove 621. The sliding block 622 passes through the sliding hole 632 and is slidably connected with the turnover plate 63. The limiting block 623 is fixedly connected with the lower end of the sliding block 622. The main body block 624 is fixedly connected with the upper end of the sliding block 622. The second sliding groove 621 is a groove formed in the lower surface of the block body and abuts against the rotating wheel 925 of the support structure 92. The limiting block 623 limits the rising height of the central beam 62, so that the central beam 62 can completely use the upward pushing force generated by the supporting framework for the tilting of the tilting plate 63 after rising to a certain height.

When the turnover device is used, the upper computer detects whether the time for turning over is up or whether a turn-over instruction is obtained. And if the patient needs to turn over, acquiring the sleeping posture information of the patient acquired by the information acquisition module.

If the patient lies down in the sleeping posture at the moment, the upper computer controls the driving structure on the left side or the right side to move. The right side is taken as an example, that is, the upper computer controls the motion of the driving structure on the right side. Make two blocks of curb plates 61 that are located right side shank board use central beam 62 to rise as the center, and then make patient's right leg crooked, make the outside perk of right side main body board 3 simultaneously, the height of lifting gradually for patient's body takes place the slope gradually. When the central beam 62 has risen to its maximum height, the continued movement of the drive mechanism causes the central beam 62 to rotate the pivotal plate about the main beam 7, thereby tilting the lower limbs along with the trunk and effecting a turn. The back of standing up can make the right leg be the left side that left leg was arranged in to crooked posture, plays the supporting role for the patient can not become prostrate from the side lying, has shifted the center of whole patient's health simultaneously, makes the patient can not reset the back at main part board 3, leads to the back not to support and makes the patient turn over back to the state of lying, makes to stand up the failure.

If the patient needs to turn over, the patient is in a lateral lying state. The drive structure of the position that the host computer control patient was recumbent on one's side for main part board 3 takes place to rotate, inclines patient's truck to the orientation of lying, and under the effect of gravity again, patient's truck just can become the state of lying on one's side from recumbent on one's side, and under the linkage effect of truck, the shank that plays the supporting role also can get back to corresponding position under the drive of truck simultaneously.

As shown in fig. 3, 4 and 5, it is considered that the process of the main body plate 3 and the leg plate returning from the inclined state to the horizontal state is smoother, rather than falling by gravity alone. The first slide groove 31 and the second slide groove 621 are both provided as T-shaped grooves. And limiting posts 926 are provided at both sides of the rotating wheel 925, and the limiting posts 926 are slidably connected with the inner wall of the first sliding groove or the second sliding groove 621.

Further, in the process of returning to the original position, the limiting pillar 926 will apply a pulling force to the central beam 62 and the main body plate 3, so that the returning speed of the main body plate 3, the central beam 62 and the supporting structure 92 is the same, and the main body plate 3 and the central beam 62 are prevented from being hit on the supporting structure 92.

Considering that the patient is not cared by people and has weak self body control force, when the patient turns over automatically, the arm of the patient is pressed under the body, and the blood circulation is influenced.

As shown in fig. 1. The headrest plate further comprises two arm plates 2 which are respectively arranged at the positions close to the two ends of the headrest plate 1. The arm plate 2 is rotatably connected with the headrest plate 1. The arm board 2 includes: one end of the strip-shaped plate body is arranged in the headrest plate 1, and the other end of the strip-shaped plate body penetrates through the headrest plate 1 to rotate freely. And the driving component is arranged on the bedstead 4, is in communication connection with an upper computer and is used for driving the strip-shaped plate body to rotate. The arm board 2 is placed on the main body board 3 in a normal state, when a patient needs to turn over, if the patient needs to turn over to lie on the left side, the upper computer can control the driving assembly to rotate the arm board 2 on the left side, so that the arm is far away from the trunk, then the arm board 2 on the right side is rotated out of the main body board 3, and the arm board 2 is prevented from influencing the overturning motion of the main body board 3. Then the turning-over operation is carried out, so that the condition that the arms are pressed under the body and the blood circulation is influenced can be avoided. After the main body plate 3 is returned to the frame 4, the arm plate 2 on the right side is returned to the main body plate 3.

So current bed or the pad of turning over is compared in this application, and the pad of turning over of this application can be crooked the standing up to patient's shank for the patient stands up back shank and forms to buckle, makes the patient turn up from flat bed and become more stable under the condition of lying on one's side, avoids taking place because the failure or the excessive problem of turning over of standing up, is particularly useful for not having the patient of autonomic regulatory ability to the limbs. In addition, the arm board 2 of this application can help the patient to swing the arm, has avoided when standing up the patient to the side and crouching, and the arm is under the health, influences the condition of blood operation. The work of medical staff is also reduced.
