Automatic buffering medical bed board assembly

Abstract

The invention discloses an automatic buffering medical board assembly. The automatic buffering medical bed board assembly comprises a bed frame, a back board, a middle bed board, a thigh board and a shank board. A medical bed further comprises a damper, a back board turning driving device comprises a first driving shaft, back board driving arms and a first linear power device, a first driving armand a driven arm are fixed to the first driving shaft, the first linear power device and the damper are hinged between the first driving arm and the bed frame as well as between the driven arm and thebed frame respectively, a buffering force exerting bush is fixed to the first driving shaft and provided with a laying-down buffering poking block and a returning poking block which are spaced circumferentially, the laying-down buffering poking block and the driven arm extrude, touch and compress the damper when the back board is laid down, and the returning poking block and the driven arm extrude and touch to lengthen and return the damper when the back board is lifted and turned. The back board of the medical bed board assembly can be rapidly laid down and has a buffering function, and therefore the automatic buffering medical bed board assembly is higher in adaptability, meanwhile can improve safety, and reduces the risk of finger or palm pinching.

Description

technical field [0001] The invention relates to a self-buffering medical bed board assembly, which belongs to the technical field of medical devices. Background technique [0002] The current medical bed includes a bed frame and a back board, an intermediate bed board, a thigh board and a calf board arranged on the bed frame. Each board is hinged to each other. The power unit is generally driven by a linear motor, and the linear motor is hinged between the backboard and the bed frame or between the thigh board and the bed frame. However, the current bed board turning device has an unreasonable structure and at least has the following disadvantages: [0003] 1. The current bed board turning device has no cushioning effect, and the bed board can only be lowered slowly, so that the bed board cannot be put down urgently in some unexpected situations. [0004] 2. When the current bed board turning device drives the bed board to turn over, the angle between the back board or the ...

AI Technical Summary

Problems solved by technology

[0003] 1. The current bed board turning device has no cushioning effect, and the bed board can only be lowered slowly, so that the bed board cannot be put down urgently in some unexpected situations.

[0004] 2. When the current bed board turning device drives the bed board to turn over, the angle between the back board or the thigh board and the middle bed board gradually decreases, which will squeeze the patient's abdomen and cause discomfort

[0005] 3. The current bed board is driven by a linear motor when it is laid down. Therefore, once the patient or others accidentally put their hands between the bed board and the bed frame, the linear motor drives the bed board to always fall and deflect, which is prone to safety accidents and even accidents. Pinching of palms or fingers

[0006] 4. The current flipping of the bed board, the flipping power device and the hinged part of the bed frame have a short service life, and frequent addition of lubricating oil is required to ensure smooth movement

[0007] 5. The bottom of the current medical bed is equipped with a placement structure for placing a light-transmitting plate, which is used for filming, but the current light-transmitting plate can only be pulled back and forth, and it is inconvenient to place and take out the light-transmitting plate

At the same time, the current medical bed generally can only take pictures at the position of the chest, and cannot realize the function of taking pictures of the whole body.
