The pain can avoid unnecessary damage during the handling process. In the clinical nursing work, it is found that the bed-ridden patient who cannot stand up on his own can save effort and is convenient to turn over the bed.

When using the traditional bed-passing tool, firstly, the operator stands on the side where the patient intends to turn, supports the patient's shoulder and buttock with both hands, gently turns the patient to the opposite side by about 30 degrees, supports the patient with the left hand, and supports the patient with the right hand. Slide the bed easy into one-third or one-half of the back of the body, release the left hand to make the patient lie on the back, and the operator uses both hands to push the bed easy to the patient's body slowly, so that the patient lies on the back The operator goes to the other side of the patient, stretches his hands from under the patient's body and pulls the edge of the bed, first pulls the bed lightly towards the operator to make the patient move towards the operator, and then pushes upwards, Make the patient turn over and lie on his side, take advantage of the situation and pull out the bed easily.

Although this kind of bed board can transfer patients, it is difficult for medical staff to complete it alone. During the process of transferring patients, the height of the bed board cannot be adjusted. It is inconvenient; and most of the existing bed boards are transferred to supine patients, which is not very practical for sitting patients.

Contents of the invention

The present invention intends to provide a bed board for a surgical trolley to solve the problem that the traditional bed board is not suitable for sitting patients and the height of the bed board is not adjustable and the application range is small.

In order to achieve the above object, the technical scheme of the present invention is as follows: the operation trolley passes the bed board, including the fixed plate and the sliding plate, the middle part of the fixed plate is provided with a through hole, both ends of the through hole are provided with chute, the two ends of the sliding plate Both are provided with bumps, and the bumps are slidably connected in the chute; the bottom of the fixed plate is fixedly connected with a plurality of first telescopic rods, and one of the first telescopic rods is fixedly connected with a cylinder, and the cylinder is slidably connected with a piston. The piston is fixedly connected with a piston rod; the end of the fixed plate close to the cylinder body is rotatably connected with an auxiliary support plate, and the end of the piston rod away from the piston is rotatably connected with the bottom of the auxiliary support plate; multiple first telescopic rods are fixedly connected with The support plate is fixedly connected with a ring gear, and the inside of the ring gear is provided with helical teeth, and a gear is meshed in the ring gear, and the gear is provided with a one-way tooth that can mesh with the helical teeth. The eccentric position of the gear is rotated and connected with a push The free end of the push rod is hinged with the first connecting rod and the second connecting rod, the free end of the first connecting rod is hinged with the first push plate, the first push plate is fixedly connected to the bottom of the fixed plate, and the second connecting rod The free end is hinged with a second push plate, and the second push plate is fixedly connected to the support plate, and a second telescopic rod is fixedly connected between the first push plate and the second push plate; the coaxial gear is fixedly connected with a screw rod, and the screw rod The upper thread is connected with a nut, the nut is fixedly connected with a driving rod, and the end of the driving rod away from the nut passes through the through hole and is fixedly connected to the bottom of the sliding plate.

With the above-mentioned technical scheme, in actual application, the first telescopic rod plays the role of overall support, the fixed plate is used to support the sliding plate, and provides a sliding track for the sliding plate, and the cylinder drives the piston rod to move, because the piston rod and the auxiliary support The plate is rotatably connected, and the auxiliary support plate is rotatably connected with the fixed plate. The movement of the piston rod drives the auxiliary support plate to rotate a certain angle along the fixed plate, so that the patient changes from a supine state to a sitting state; the ring gear acts as a fixed gear. The gear is provided with a one-way tooth that can mesh with the helical teeth, so that the gear can only move in one direction along the ring gear; the rotation of the gear drives the push rod connected to the eccentric position to reciprocate, and the reciprocating motion of the push rod drives the first joint hinged with it. The first connecting rod and the second connecting rod move, because the first connecting rod and the second connecting rod have the same hinge point, the other end of the first connecting rod and the other end of the second connecting rod are hinged with the first push plate and the second connecting rod respectively. Two push pedals, and a second telescopic rod is fixedly connected between the first push pedal and the second push pedal, so that the first push pedal and the second push pedal can only produce displacement in the vertical direction, so that the first push pedal and the second push pedal can only be displaced in the vertical direction.
