Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a transfer vehicle for critically ill patients. Background Art

[0002] The transfer cart is used to move and transfer patients who have difficulty in moving before and after surgery, and to move patients from the bed to the transfer cart, and then to the operating table or equipment that needs examination / treatment, or vice versa. For critically ill patients, due to physical weakness, unhealed wounds or other serious health problems, their mobility is greatly limited, and they are often unable to move from one location to another independently. In this case, the transfer cart becomes an indispensable and important tool in their transfer process.

[0003] Although there are many types of transfer carts for critically ill patients on the market, their safety performance has shown many shortcomings in actual use. For example, the transfer carts lack effective fixing devices or buffering measures. Patients are prone to slipping or being hit due to bumps and shaking during the transfer process, which in turn aggravates the pain of the wound and even causes new injuries. When transferring heavier patients, the beds are often difficult to maintain sufficient stability and are prone to safety hazards such as rollover. Summary of the invention

[0033] The inner wall of the movable groove 17 is rotatably connected with the screw rod 19, the outer wall of the screw rod 19 is threadedly connected to the inner wall of the movable block 18, and the bottom outer wall of the mounting frame 14 is fixedly connected with the motor 3 20, and the output shaft of the motor 3 20 is connected to one end of the screw rod 19.

[0034] In this embodiment, after the fixation is completed, the motor 2 9 is started to drive the screw rod 8 to rotate, the screw rod 8 drives the moving block 10 to move in the direction close to the patient, the moving block 10 drives the connecting plate 11 connected thereto to move, the connecting plate 11 drives the receiving plate 12 to move accordingly, the conveyor belt 13 on the outside of the receiving plate 12 moves, and the mounting frame 14 at the bottom of the connecting plate 11 and the structure on the mounting frame 14 also move accordingly; the motor 4 27 is started to drive the rotating roller 2 16 to rotate, and with the cooperation of the rotating roller 15, the conveyor belt 13 rotates clockwise, and the conveyor belt 13 is stationary relative to the patient; when the patient's body moves to the conveyor belt 13 and the receiving plate 12, the motor 2 9 drives the screw rod 8 to rotate in the opposite direction, driving the patient to move toward the bed frame 5.

[0035] Move the patient to the bed to be transferred, start the motor 29 to drive the screw rod 8 to rotate, and the moving block 10 drives the connecting plate 11 and other structures to move toward the bed.

When the receiving plate 12 gradually moves under the patient's body, the patient falls into the groove 21. The water bag 23 and the airbag bag 22 cushion the patient's fall. When the patient's body falls into the groove 21, the airbag bag 22 releases some of the gas and limits the patient's body through the groove 21 to prevent the patient from slipping.

[0044] Embodiment three:

[0045] See also Figure 1-Figure 9 As shown, on the basis of Example 1 and Example 2, the present invention provides a technical solution: an anti-dumping device 3 is arranged on the base 1, and the anti-dumping device 3 includes a support rod 301, a connecting rod 304 is fixedly connected between the outer walls of the left and right support rods 301, a vacuum suction cup 302 is fixedly connected to the bottom end of the support rod 301, a threaded rod 303 is arranged on the top of the support rod 301, a transmission wheel 305 is rotatably connected to the top outer wall of the base 1, one end of the threaded rod 303 is fixedly connected to the outer wall of the transmission wheel 305, the outer wall of the threaded rod 303 is threadedly connected to the inner wall of the base 1, a belt 306 is arranged on the outer side of the transmission wheel 305, the two transmission wheels 305 are connected through the belt 306, and a motor 307 is arranged on the top of the base 1, and the output shaft of the motor 307 is connected to the transmission wheel 305.

[0046] A vacuum pumping device 308 is fixedly connected to the top outer wall of the base 1 . A vacuum pumping tube 309 is provided at the output end of the vacuum pumping device 308 . The other end of the vacuum pumping tube 309 is provided in the vacuum suction cup 302 .

[0047] In this embodiment, the motor 307 drives the threaded rod 303 to rotate, and the threaded rod 303 drives the support rod 301 to move downward, so that the vacuum suction cup 302 contacts the ground, and the air in the vacuum suction cup 302 is extracted by the vacuum device 308, so that the vacuum suction cup 302 is tightly fixed to the ground, thereby increasing the stability of the device when in use and avoiding rollover caused by a heavy patient.

[0048] Working principle: When in use, the device is moved to the hospital bed or operating bed via the moving wheel 2, and the electric lifting rod 4 is started to adjust the height of the bed frame 5 to make it consistent with the height of the hospital bed or operating bed. After the adjustment is completed, the moving wheel 2 is locked; the motor 307 is started to drive the threaded rod 303 to rotate, and the threaded rod 303 drives the support rod 301 to move downward, so that the vacuum suction cup 302 contacts the ground, and the air in the vacuum suction cup 302 is sucked away by the vacuum device 308, so that the vacuum suction cup 302 is tightly fixed to the ground, thereby increasing the stability of the device when in use and avoiding rollover caused by heavy patients.

[0049] After the fixation is completed, the starting motor 29 drives the screw rod 8 to rotate, and the screw rod 8 drives the moving block 10 to move in the direction close to the patient, and the moving block 10 drives the connecting plate 11 connected thereto to move, and the connecting plate 11 drives the receiving plate 12 to move accordingly, and the conveyor belt 13 on the outside of the receiving plate 12 moves, and the mounting frame 14 at the bottom of the connecting plate 11 and the structure on the mounting frame 14 also move accordingly; the starting motor 4 27 drives the rotating roller 2 16 to rotate, and with the cooperation of the rotating roller 15, the conveyor belt 13 rotates clockwise, and the conveyor belt 13 is stationary relative to the patient; when the patient's body moves to the conveyor belt 13 and the receiving plate 12, the motor 29 drives the screw rod 8 to rotate in the opposite direction, driving the patient to move toward the bed frame 5.

[0050] Move the patient to the bed to be transferred, start the motor 29 to drive the screw rod 8 to rotate, and the moving block 10 drives the connecting plate 11 and other structures to move toward the bed. After the patient is placed on the bed, stop the rotation of the motor 4 27, and then start the motor 29 to drive the screw rod 8 to rotate in the opposite direction, drive the connecting plate 11 and other structures to move toward the bed frame 5 and restore them to their original positions.

[0051] When moving the patient, the inflation and deflation device 24 is started to inflate the airbag bag 22 to expand it. When the receiving plate 12 gradually moves under the patient's body, the patient falls into the groove 21. The water bag 23 and the airbag bag 22 cushion the patient's fall. When the patient's body falls into the groove 21, the airbag bag 22 releases a portion of the gas to limit the patient's body through the groove 21 to prevent the patient from slipping. When the patient's body moves into the groove 21, the motor three 20 is started to drive the screw rod two 19 to rotate, and the screw rod two 19 drives the moving block two 18 to move upward, so that the length of the upper conveyor belt 13 becomes longer, which facilitates the conveyor belt 13 to sink into the groove 21. When the movement is completed, the motor three 20 is started to drive the moving block two 18 to move upward, thereby indirectly achieving the tensioning of the conveyor belt 13.
