The invention has the following advantages: when the mechanical pressing device for sudden respiratory arrest in emergency department is used, the working process is as follows:
when sudden cardiac arrest of a patient occurs, as shown in fig. 1, 3 and 4, as shown in fig. 1, the clamping block 2 inside the clamping frame 1 is completely located in the sliding groove 36, so that the clamping frame 1 is conveniently and directly and quickly clamped on a bed frame of a sickbed, the whole device is quickly installed, the rotating shaft I4 is rotated, the rotating shaft I4 synchronously drives the screw rod III 37 to rotate, the clamping block 2 slides out of the sliding groove 36 through threaded transmission, as shown in fig. 4, the inner right angle of the clamping block 2 is clamped with the bed frame, the clamping frame 1 is quickly fixed on the bed frame, the threaded transmission is adopted, the axial self-locking characteristic of threads is utilized, no additional parts are needed, the structure is simple, the operation is convenient, the whole device is quickly installed on the sickbed, and the rescue success rate is improved.
After the clamping frame 1 is installed, the first support 6 is driven to move in the horizontal direction through the first rotating screw rod 7 by utilizing the threaded transmission, so that the first support 6 drives the second support 11 and the driving mechanism and the pressing mechanism on the second support 11 to move in the horizontal direction through the flat plate 9 and the second slide rod 12, and the second support 11 is driven to move up and down in the vertical direction through the second rotating screw rod 10 by utilizing the threaded transmission, so that the second support 11 synchronously drives the driving mechanism and the pressing mechanism on the second support to move in the horizontal direction, and the position of the pressing mechanism is adjusted quickly and stably, and the proper pressing position can be adjusted according to the body types and the heart positions of different patients, so that the accurate rescue operation is improved, and the rescue success rate of the patients is improved.
After the pressing position of the pressing mechanism is adjusted according to the body shape and the heart position of a 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 31 to rotate, the gear ring 30 drives the gear 29 and the rotating shaft II 28 to rotate, the rotating shaft II 28 drives the sliding sleeve 25 to rotate through the multi-edge rod 26, the sliding sleeve 25 synchronously drives the worm 33 to rotate, 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 swinging rod 15 through the connecting rod I14, as shown in fig. 1 and 3, the swinging rod 15 swings up and down around the left end of the swinging rod, and in the process of swinging up and down around the left end of the swinging rod 15, the side wall of the bar hole 16 and the pin rod 19 drive the pressing rod 18 to move up and down, so that the pressing rod 18 can reciprocate and press the heart part of the patient through the saccule 24, and the upper and lower strokes of the pressing rod 18 are unchanged due to the fact that the position and the diameter of the rotary disc 31 are unchanged, so that the pressing rod 18 drives the saccule 24 to press force is unchanged, and the pressing force of the pressing rod 24 is ensured to be uniform and the frequency is stable and not changed.
In the process of the up-and-down movement of the compression bar, the convex ring 22 stretches or compresses the spring 21, so that vibration generated by the up-and-down movement of the compression bar 18 is buffered through deformation of the spring 21, and the damage to a patient is reduced.
As shown in fig. 2, the piston rod of the air cylinder 32 drives the strut to move left and right, so that the strut drives the second rotating shaft 28 to move left and right through the collar 27, and then the second rotating shaft 28 synchronously drives the gear 29 to move left and right, so that the gear 29 is meshed with the gear rings 30 with different diameters on the turntable 31, and as the angular speeds of the turntable 31 and the gear rings 30 thereon are fixed, the gear rings 30 with different diameters drive the gear 29 to rotate at different speeds, the larger the diameter of the gear ring 30 drives the gear 29 to rotate, so that the larger the speed of the gear 29 drives the turbine 17 to rotate through the second rotating shaft 28, the polygonal rod 26, the sliding sleeve 27 and the worm 33, the smaller the opposite is, thereby realizing that the frequency of the up-and-down movement of the pressing rod 18 is changed through the first connecting rod 14 and the swinging rod 15, and further realizing the adjustment of the pressing frequency of the balloon 24, and thus the adjustment of 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, and when the pressure rod 18 drives the balloon 24 to move upwards for resetting, the spring plate 39 is not stressed and resets under the action of the restoring force, so that the buffering effect is generated on the pressing operation through the reciprocating deformation of the spring plate 39, thereby reducing the injury to a patient, the internal pressure of the balloon 24 is increased after the balloon 24 is stressed, the conducting direction of the one-way valve 41 points to the volute 3, the conducting direction of the one-way valve 2 points to the balloon 24, thereby enabling air in the balloon 24 to be conveyed into the volute 3 through the first air pipe, as shown in fig. 5, enabling the impeller 44 to drive the rotating shaft 4 to rotate under the action of air flow, enabling the clamping block 2 to be further driven by the screw rod III 37, further enabling the clamping block 1 to be connected with the bed frame firmly, avoiding shaking generated when the sickbed is pressed, and when the sickbed is moved, from causing the whole device to be loose, even being separated from the sickbed, and further enabling the air to enter the air supplementing mechanism to be automatically clamped into the air pipe 24 when the balloon 24 is pressed, and the air supplementing mechanism is enabled to be clamped in the first air pipe 43 when the air is reset, and the air supplementing mechanism is enabled to be compressed into the air channel to be compressed, and the air is enabled to be compressed in the air channel to be in the emergency, and the emergency, when the emergency operation is enabled to be compressed, and the air is enabled to be compressed.
After the rescue is finished, the first rotating shaft 4 is reversely rotated to enable the third screw rod 37 to reversely rotate, so that the clamping block 2 slides into the sliding groove 36 under the action of screw thread transmission, and further the rest of the frame of the clamping block 2 is separated, so that the clamping frame 1 is taken down from the frame, the operation is simple and convenient, the disassembly and the assembly are convenient, and the time and the labor are saved.
