There is an air passage 19 inside the vertical rod 3, and the lower end of the air passage 19 is located at The lower end surface of the vertical bar 3 and the upper end of the air channel 19 are located in the air bag 17, and the sliding sleeve 18 will never cross the upper port of the air channel 19 during the sliding process. When the vertical bar 3 moves down to the lowest position with the flat plate 2, the vertical bar The lower end of 3 is pressed on the lower side inner wall of bottom box 1, and the lower port of airway 19 is closed; The air pressure inside rises to expand the airbags 17 on these vertical poles 3 through the air passage 19, and the airbags 17 expand to fill the gap between the wounded and the peripheral vertical poles 3, and completely hug the wounded, while the vertical poles under the patient Rod 3 moves down to lowest position along with plate 2, and the lower port of air channel 19 can be closed, so the air pressure in bottom box 1 can't act in the air bag 17 on these vertical rods 3, and the air bag 17 on these vertical rods 3 can't will swell.

Sealing rings 20 are installed at the joints of the vertical bar 3 and the bottom box 1 and the joints of the sliding sleeve 18 and the vertical bar 3 to ensure the airtightness in the bottom box 1 and the air bag 17 .

After the air cushion 16 is inflated and inflated, a plurality of grooves 21 are provided at the bottom thereof, and horizontal bars can be inserted into the grooves 21 to lift the air cushion 16 and the patient.

A plurality of stoppers 10 of each vertical bar 3 are evenly distributed around the circumference, and when the plate 2 presses the vertical bar 3 outward through the stoppers 10, the force on the vertical bar 3 is more balanced.

In the initial state, the height of the slide bar 8 above the upper surface of the flat panel 2 is greater than 5 centimeters, so that after the patient is transferred onto the flat panel 2, the slide bars 8 positioned under the patient's body will be depressed, so that these slide bars The bar 8 pushes out the block 10 below it, and the lower end of the block 10 extends below the flat plate 2 .

The upper surface of the air cushion 16 is pasted with a smooth plastic film to reduce the resistance between the air cushion 16 and the patient when it is pulled under the patient.

In the initial state, the plate 2 is lifted to a higher position, the limit shoulder 5 at the lower end of the vertical rod 3 is in contact with the inner wall of the bottom box 1, the upper end of the vertical rod 3 is retracted into the plate 2, and the first spring 6 is under compression state, the upper end of the slide bar 8 is higher than the flat plate 2, the second spring 9 is at the original length, the outer end of the block 10 is retracted into the vertical bar 3, and the third spring 11 is at the original length; there is a lower air pressure in the bottom box 1, A certain upward supporting force is provided to the vertical bar 3, so that the vertical bar 3 will not drop when the external force does not act downward.

When transporting the injured, first pull the air cushion 16 from the patient's head or feet to the patient's body, and slowly pull the air cushion 16 so as not to drive the injured limbs. If necessary, apply lubricant on the air cushion 16 to reduce resistance; After the air cushion 16 is pulled under the patient, inflate the air cushion 16 to expand it. The degree of inflation should make the air cushion 16 have a certain rigidity to facilitate lifting. 16 and the patient are lifted onto the flat panel 2, and then the air cushion 16 is deflated and pulled out slowly; before the air cushion 16 is lifted onto the flat panel 2, four hydraulic cylinders 4 are activated to lift the flat panel 2 upward, and the vertical rod 3 is driven by the shaft The spacing of the shoulder cannot move upwards, and the first spring 6 is further compressed until the upper surface of the flat plate 2 is raised to be flush with the upper end surface of the slide bar 8 to form a plane. The purpose of doing this is to extract the air cushion 16 for convenience.

After the patient is transferred onto the flat panel 2, four hydraulic cylinders 4 are started to pull the flat panel 2 back to the height of the initial state. At this time, the upper ends of the slide bars 8 that are not positioned under the patient's body are still higher than the flat panel 2. These slide bars 8 The stopper 10 on the vertical bar 3 does not protrude, and the slide bar 8 under the patient's body will be pressed down by the patient for a certain distance. Downside; then the plate 2 is pulled down by four hydraulic cylinders 4, the vertical bar 3 that is not pressed by the patient remains stretched out under the action of the bottom air pressure, and the vertical bar 3 under the patient is due to the stopper 10 on it Stretch out below the plate 2, so it will be pulled by the plate 2 and move downward synchronously. After the plate 2 drops to the lowest position, the lower ends of these vertical rods 3 will be pressed against the bottom wall of the bottom box 1; The vertical rod 3 will surround the wounded to form a circle identical to the outline of the wounded. Whatever posture the wounded is, the surrounding circle is exactly what posture, and the posture of the wounded is fixed as a whole.

After the flat panel 2 moves down to the lowest position, the bottom box 1 is inflated through the air intake pipe 12, and the lower end of the air passage 19 in the vertical rod 3 that keeps extending is still in an open state, so the air pressure in the bottom box 1 will pass through. The air passage 19 acts on the airbags 17 on these vertical rods 3, and the airbags 17 on the vertical rods 3 that remain stretched out can be blown up and expanded, and the airbags 17 expand to make up the gap between the wounded and the peripheral vertical rods 3, The wounded is fully hugged and fixed for transfer; and the lower end of the vertical bar 3 pressed down by the flat plate 2 is pressed against the bottom wall of the bottom box 1, and the lower ports of the air passages 19 in these vertical bars 3 are closed, and the air passages in the bottom box 1 are closed. Air pressure can not act on the lower ends of these vertical rods 3, nor can it act in the air bag 17 on these vertical rods 3, so the vertical rod 3 that is depressed is not subject to upward pressure and the air bag 17 does not expand.

After transporting the wounded to the hospital, open the switch valve 15 on the exhaust pipe of the bottom box 1 to release the pressure in the bottom box 1, and the air bag 17 shrinks, and then start four hydraulic cylinders 4 to lift the flat panel 2 to the level with the slide bar 8. When the upper end is in the same position, the air cushion 16 can be used to transfer the wounded to the treatment place.

The present invention can keep the injured person's original posture through the air cushion 16 and transfer the injured person to the flat panel 2 without moving or distorting the injured person's limbs during the transportation process, and the injured person's body is not stressed; The vertical bar 3 and the flat panel 2 move down, and the unpressed vertical bar 3 keeps stretching out to form a contour surrounding the wounded, and the airbag 17 is inflated to completely hug the wounded, so that the wounded's limbs will not be passive Or unconscious activities, so as to avoid secondary damage to the injured during the transfer process.
