When the patient's arm is not hung, the ring frame 511 has no load. At this time, the piston block 506 is at the lower end under the action of the inflatable reset spring 505, and the inflatable inner ring 510 is not inflated. When the arm passes through the ring frame 511, the ring frame 511 will be subjected to a downward pulling force, so that the piston rod 502 can be pulled upward, and the piston block 506 will press the gas into the inflatable inner ring 510, so that the inflatable inner ring 510 expands, so as to increase the contact area with the arm and avoid the problem of strangulation marks caused by too little force. When disassembling later, you only need to put down the arm. At this time, the ring frame 511 loses the pulling force. Under the reset of the inflatable reset spring 505, the piston block 506 will move upward, so as to remove the air in the inflatable inner ring 510, release the lock on the arm, and facilitate the later release;

Under the guidance of the guide vertical bar 606, the weight support plate 607 can move downward along the guide vertical bar 606. When the suspension position changes, the weight block 609 still does not shake, thereby ensuring the stability of the suspension;

[0040] A locking side block 620 is provided at the lower end of the mounting side plate 615, and a third locking bolt 621 is screwed on the locking side block 620 to lock the side of the rotating shaft 614, so that the position of the rotating shaft 614 can be limited;

[0041] The upper end of the base 100 is provided with a binding positioning component for auxiliary positioning, and the base 100 can be connected to the raised block on the side of the bed through the binding positioning component, so that the device is more stable to use. The binding positioning component includes a floating vertical plate 301 fixed to the upper end of the base 100, and a floating seat 302 is slidably provided on the floating vertical plate 301.

By rotating the first locking bolt 303, the locking pressure plate 304 squeezes the raised block on the side of the bed, thereby completing the fixed connection between the equipment and the bed position.

[0042] The downward pressing self-locking component includes a downward pressing slide bar 404 arranged at the middle position of the lower end of the base 100, a downward pressing slide sleeve 402 is provided on the sliding sleeve 402 at the lower end of the downward pressing slide bar 404, a downward pressing locking plate 401 is provided at the lower end of the downward pressing sliding sleeve 402, the downward pressing locking plate 401 and the base 100 are connected by a downward pressing spring 403, an anti-slip layer is provided at the lower end of the downward pressing locking plate 401, the cross-sections of the downward pressing slide sleeve 402 and the downward pressing spring 403 here are rectangular or elliptical, a vertical slide bar 400 is provided at the upper end of the downward pressing locking plate 401, the upper end of the vertical slide bar 400 passes through the vertical through hole at the upper end of the base 100, and the vertical A traction block 405 is provided at the upper end of the straight sliding rod 400, and the traction block 405 is connected to one end of an elastic traction rope 406, and the other end of the elastic traction rope 406 is connected to the lifting rod 612 by passing through a guide wheel 407 on the base 100, and the guide wheel 407 is rotatably arranged on a vertical side plate on the base 100. When the device is in use, when the lifting rod 612 slides upward along the lifting sleeve 611, one end of the elastic traction rope 406 will be pulled, so that the traction block 405 moves downward along the base 100, and the traction block 405 drives the downward locking plate 401 to move downward, thereby pressing against the ground, thereby completing the locking of the entire device;

[0043] The self-locking method here is automatically completed when the equipment is raised, and the equipment can only move by itself after it is lowered. This ensures the stability of the equipment movement and avoids the problem of tipping due to excessive center of gravity.

[0044] The lifting and pushing assembly includes a lifting screw hole arranged at the lower end of a lifting rod 612, in which a lifting screw 602 is matched, and the lower end of the lifting screw 602 is rotatably connected to the upper end of a fixed column 103, and a first gear 601 is fixedly provided on the lifting screw 602, and the side surface of the first gear 601 is meshed with the second gear 605, and the second gear 605 is connected and fixed to a lifting turntable 604, and the lifting turntable 604 is rotatably arranged on a lifting sleeve 611, and the second gear 605 is driven to rotate by the lifting turntable 604, and the second gear 605 is matched with the first gear 601 to drive the lifting screw 602 and the lifting rod 612 to rotate relative to each other, and under the action of the thread, the lifting rod 612 will move up and down along the lifting sleeve 611 to provide power for the lifting and lowering of the hoisting, and a scale bar may also be provided on the outside of the lifting rod 612 to provide a reference for height adjustment.

[0045] Working principle: Move the device to one side of the bed, and connect the base 100 to the raised block on the side of the bed by binding the positioning assembly, so that the device is more stable to use. The lifting turntable 604 drives the second gear 605 to rotate, and the second gear 605 matches the first gear 601 to drive the lifting screw 602 and the lifting rod 612 to rotate relative to each other. Under the action of the thread, the lifting rod 612 will move up and down along the lifting sleeve 611 to adjust the height of the airbag set 500. When using the device, when the lifting rod 612 slides upward along the lifting sleeve 611, one end of the elastic traction rope 406 will be pulled, so that the traction block 405 moves downward along the base 100, and the traction block 405 will drive the downward locking plate 401 to move downward, thereby pressing tightly against the ground to complete the locking of the entire device;

[0046] Then the patient's arm is passed through the inflatable inner ring 510. When the arm passes through the ring frame 511, the ring frame 511 will be subjected to a downward pulling force, so that the piston rod 502 can be pulled upward, and the piston block 506 will press the gas into the inflatable inner ring 510, thereby expanding the inflatable inner ring 510 to increase the contact area with the arm and avoid the problem of strangulation marks caused by insufficient force. The weight block 609 is placed on the weight support plate 607 at the other end of the hanging rope 610 to provide sufficient traction. Under the guidance of the guide vertical bar 606, the weight support plate 607 can move downward along the guide vertical bar 606. When the hanging position changes, the weight block 609 will still not shake, thereby ensuring the stability of the suspension.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
