Description

Technical Field

[0001] The invention relates to an examination bed, in particular to a multifunctional bed specially used for examination of pregnant women. Background Art

[0002] During pregnancy, especially after 6 to 7 months, most women will have difficulty in moving. It is difficult for them to lie down or get up in bed and they need external force. At present, the examination beds used in the examination departments of hospitals, such as the B-ultrasound room, are flat beds without guardrails, which are not convenient for pregnant women to lie down or get up. In addition, in order to facilitate the operation of medical staff, the height of the flat bed is usually not low, and these examination departments usually do not allow the spouse of the pregnant woman to enter. Therefore, it is difficult for pregnant women to get in and out of bed when they are examined alone, and it is not easy to lie down and get up. Therefore, it is very necessary to design a special bed that is convenient for pregnant women to get in and out of bed, lie down and get up. Summary of the invention

[0005] A front driving rod is threadedly matched with the inner thread of the driving screw tube, and a rolling disk is provided at one end of the front driving rod extending out of the driving screw tube. A leg board for placing the user's legs is rotatably connected to one end of the hip board, and a support block with an inclined surface is provided on the lower plane of the leg board, and a rolling groove matching the rolling disk is provided on the inclined surface of the support block. When the motor drives the driving screw tube to rotate and lift the hip board upward, the driving screw tube can drive the front driving rod inside it to move axially in the direction away from the driving screw tube, thereby forcing the rolling disk to roll along the rolling groove and push the support block to move outward until the leg board rotates to a horizontal position; when the motor drives the driving screw tube in reverse to move the hip board downward, the rolling disk moves axially in the direction close to the driving screw tube, and the leg board rotates downward under the action of gravity until it is perpendicular to the horizontal plane;

A motor 19 is fixed on the L-shaped support plate 18. A second gear 20 matching the first gear 17 is provided on the rotating shaft of the motor 19. The second gear 20 is driven to rotate by the rotating shaft of the motor 19, thereby driving the first gear 17 to rotate, forcing the driving solenoid 15 to rotate, thereby forcing the transmission block to move axially along the driving solenoid 15, thereby adjusting the angle between the support rod 5 and the horizontal plane, and realizing the lifting function of the hip plate 8;

[0033] Of the two first sliding blocks 4 in the slide rail mechanism, one is fixed to the U-shaped seat 2 via a locking screw 32 , and the other reciprocates on the slide rod 3 .

[0034] A button 30 for controlling the forward and reverse rotation of the motor is provided at the edge of the lower end surface of the hip plate 8. This structure can prevent the entire bed body from sliding along the U-shaped seat.

[0035] The working process of this embodiment:

[0036] The medical staff first presses the down button at the bottom of the hip board, and the hip board is driven by the motor to descend to the lowest point. The leg board is vertically downward, and the back board is 60°-80° with the horizontal plane. The whole device is chair-shaped. The pregnant woman slowly sits on the hip board like sitting on a chair. Then the medical staff presses the up button to lift the hip board to the highest point. At the same time, the leg board and the back board will gradually flip over to coincide with the hip board plane under the action of the internal structure. The whole device is bed-shaped, and the height is suitable for medical staff to do examinations;

[0037] After the examination, the medical staff pressed the down button again to adjust the device into a chair shape to make it easier for the pregnant woman to get out of bed.
