The invention has the advantages that: when the mechanical pressing device for emergency department sudden breathing stop is used, the working process is as follows:

as shown in fig. 1, fig. 3 and fig. 4, when the sudden cardiac arrest of a patient occurs, as shown in fig. 1, the fixture block 2 inside the fixture frame 1 is completely located in the chute 36, so that the fixture frame 1 can be directly and quickly clamped on the bed frame of a hospital bed, thereby facilitating the quick installation of the whole device, and then rotating the first rotating shaft 4, so that the first rotating shaft 4 synchronously drives the third screw rod 37 to rotate, and the fixture block 2 slides out of the chute 36 through thread transmission, as shown in fig. 4, so that the inner right angle of the fixture block 2 is clamped with the bed frame, thereby rapidly fixing the fixture frame 1 on the bed frame, and adopting thread transmission, utilizing the axial self-locking characteristic of threads, without additional parts for fixation, the structure is simple, the operation is convenient, and rapidly installing the whole device on the hospital bed frame, thereby facilitating the improvement of the success rate of rescue.

After the clamping frame 1 is installed, the first support 6 is driven to move in the horizontal direction through rotating the first screw rod 7, so that the first support 6 passes through the flat plate 9, the second slide rod 12 drives the second support 11 and the driving mechanism and the pressing mechanism on the second support 11 to move in the horizontal direction, the second support 11 is driven to move up and down in the vertical direction through rotating the second screw rod 10 through screw transmission, the second support 11 is driven to move in the horizontal direction of the driving mechanism and the pressing mechanism on the second support in a synchronous mode, the position of the pressing mechanism can be adjusted quickly and stably, the appropriate pressing position can be adjusted according to the body types and the heart positions of different patients, accurate rescue operation is improved, and the success rate of rescue of the patients is improved.

After the pressing position of the pressing mechanism is adjusted according to the body type and the heart position of the patient, the motor 13 is started to work, the motor 13 drives the rotary disc 31 and each gear ring 30 on the upper surface of the rotary disc to rotate, so that the gear rings 30 drive the gear 29 and the second rotating shaft 28 to rotate, so that the second rotating shaft 28 drives the sliding sleeve 25 to rotate through the multi-edge rod 26, so that the sliding sleeve 25 synchronously drives the worm 33 to rotate, so that the worm 33 drives the turbine 17 to rotate, the rotation of the turbine 17 applies pulling force or pushing force to the right end of the swing rod 15 through the first connecting rod 14, as shown in fig. 1 and 3, so that the swing rod 15 swings up and down around the left end of the swing rod 15, the side wall of the strip-shaped hole 16 and the pin rod 19 drive the pressing rod 18 to move up and down in the process of swinging up and down around the left end of the swing rod 15, so that the pressing rod 18 performs reciprocating and circulating pressing on the heart position of the patient through the saccule 24, and the position and the diameter of the rotary disc 31 are unchanged, therefore, the up-down stroke of the compression rod 18 is not changed, so that the pressing force of the compression rod 18 driving the balloon 24 is not changed, the uniform force during each pressing is ensured, and the frequency is stable and unchanged.

The spring 21 is stretched or compressed by the convex ring 22 in the process of the up-and-down movement of the compression rod, so that the vibration generated by the up-and-down movement of the compression rod 18 is buffered by the deformation of the spring 21, and the injury to a patient is reduced.

As shown in fig. 2, the piston rod of the cylinder 32 drives the support rod to move left and right, so that the support rod drives the second rotating shaft 28 to move left and right through the lantern ring 27, thereby enabling the second rotating shaft 28 to synchronously drive the gear 29 to move left and right, enabling the gear 29 to be meshed and connected with gear rings 30 with different diameters on a rotating disc 31, since the angular velocity of the turntable 31 and the respective ring gears 30 thereon is fixed, the different diameters of the ring gears 30 cause the gear 29 to rotate at different speeds, and the larger the diameter of the ring gear 30, the greater the speed at which the gear 29 is caused to rotate, so that the gear 29 drives the turbine 17 to rotate at a higher speed through the second rotating shaft 28, the polygonal rod 26, the sliding sleeve 27 and the worm 33, and vice versa, thereby realizing that the frequency of the up-and-down movement of the compression bar 18 is changed through the first connecting rod 14 and the swing rod 15, and further realizes the adjustment of the pressing frequency of the balloon 24, so that different pressing frequencies can be adjusted according to different rescue stages.

In the process of pressing the balloon 24, the balloon 24 is flattened, as shown in fig. 6, and the spring plate 39 tends to be flat, so that the spring plate 39 obtains a restoring force, when the pressing rod 18 drives the balloon 24 to move upwards and return, the spring plate 39 is not pressed and returns under the action of the restoring force, so that the pressing operation is buffered through the reciprocating deformation of the spring plate 39, so that the injury to a patient is reduced, after the balloon 24 is pressed, the internal pressure is increased, because the conduction direction of the first check valve 41 points to the volute 3, and the conduction direction of the second check valve 42 points to the balloon 24, so that the air in the balloon 24 is conveyed into the volute 3 through the first air pipe, as shown in fig. 5, the impeller 44 drives the first rotating shaft 4 to rotate under the action of air flow, so that the first rotating shaft 4 further drives the bed frame 2 to press the bed frame through the third screw 37, and further realizes that the connection between the clamping frame 1 and the bed frame is more stable, thereby avoid pressing during operation and rocking that the sick bed produced when removing and lead to whole device and sick bed not hard up, break away from even, and then ensure the stability of rescue operation, improve the success rate of rescuing to when sacculus 24 resets, inside produces suction, and makes in the air gets into sacculus 24 through trachea two 43, realizes automatic tonifying qi, so that drive tight bedstead of mechanism clamp certainly when next time pressing.

After the rescue is finished, the first reverse rotation rotating shaft 4 enables the third screw rod 37 to reversely rotate, so that the clamping block 2 slides in the sliding groove 36 under the action of thread transmission, the rest bed frame of the clamping block 2 is separated, the clamping frame 1 is taken down from the bed frame, and the multifunctional rescue tool is simple and convenient to operate, convenient to disassemble and assemble, time-saving and labor-saving.
