In order to prevent the connecting pipe from moving around, the upper end of the box body 3 is provided with a pipe clamp.

When the medical bed is used, the supporting plate 1 is placed on the horizontal bed board, a medical worker can press two L-shaped clamping blocks 20 towards the middle by using two hands, the clamping blocks 20 extrude the second springs on the corresponding sides of the clamping blocks, when the clamping blocks 20 are separated from the clamping plates 19 on the corresponding sides of the clamping blocks, the U-shaped plate 2 is lifted upwards, then the upper body of the patient lies above the supporting plate 1 in a flat mode, the head of the patient is placed above the soft cushion, the lower jaw of the patient can be lifted by the inclined plane at the upper end of the soft cushion, the air passage of the patient is opened, the medical worker needs to clean foreign matters in the nose of the patient, then the right end of the U-shaped plate 2 swings downwards until the clamping plates 19 on the right end of the U-shaped plate 2 extrude the clamping blocks 20 on the corresponding sides of the U-shaped plate and clamp the clamping blocks 20, and at the moment, the pressing cushion is attached to the chest of the patient;

the medical staff takes the connecting pipe out of the pipe clamp, then covers the opening end of the respiratory mask 18 at the mouth and nose of the patient and starts the motor 23, the output end of the motor 23 drives the sleeve 25 to rotate through the transmission plate 26 and the spherical convex block, the sleeve 25 drives the two transverse shafts to synchronously rotate through the belt and the belt wheel, the transverse shafts drive the eccentric wheel 27 to rotate, the eccentric wheel 27 drives the rectangular frame 10 on the corresponding side to swing up and down through the circular ring 31, the two rectangular frames 10 drive the pressing plate 11 to reciprocate up and down through the pressing rod 12, and the pressing plate 11 presses the chest cavity of the patient through the pressing pad;

when the motor 23 rotates, the rotating shaft 4 is driven to rotate through the pair of bevel gears 24, the rotating shaft 4 drives the circular plate 21 to rotate, the circular plate 21 drives the sliding block 7 to slide in a reciprocating mode left and right through the connecting rod 22, the sliding block 7 drives the two wedge-shaped blocks 8 to move in a reciprocating mode left and right, the two wedge-shaped blocks 8 drive the rotating disc 5 to rotate anticlockwise through the extrusion fixing blocks 6, the rotating disc 5 drives the supporting disc 13 to rotate anticlockwise through the supporting shaft, the supporting disc 13 drives the arc-shaped plate 30 and the arc-shaped rack 32 to rotate anticlockwise, and the rotating angle of the rotating disc 5 is equal to the included angle between every two adjacent fixing blocks 6 when the motor 23 rotates for one circle;

after the motor 23 rotates the ring, the pressing pad finishes pressing the chest cavity of the patient for the second time, the arc-shaped plate 30 starts to press the moving block 28 leftwards, the moving block 28 compresses the compression spring leftwards and drives the pressing column 29 to move leftwards, because the arc length corresponding to the arc-shaped plate 30 is slightly larger than the arc length corresponding to the arc-shaped rack 32, the arc-shaped rack 32 and the gear are in a non-meshed state at the moment, the spherical convex block between the two transmission plates 26 is separated after the pressing column 29 moves leftwards, the sleeve 25 at the output end of the motor 23 stops rotating, namely the two transverse shafts stop rotating, and the pressing pad stops pressing the chest cavity of the patient;

when the supporting disk 13 rotates counterclockwise for a certain angle, the arc-shaped rack 32 is engaged with the gear, the arc-shaped rack 32 drives the cylindrical gear 33 to rotate, the cylindrical gear 33 drives the cam 14 to rotate through the pin shaft, because the first spring is arranged between the piston 16 and the cylinder 15, the cam 14 drives the piston 16 to slide back and forth in the cylinder 15 through the T-shaped rod 17, the gas in the cylinder 15 firstly enters the lung of the patient through the connecting pipe and the breathing mask 18, then the gas in the lung of the patient is sucked into the cylinder 15, when the patient is subjected to artificial respiration, the arc-shaped rack 32 drives the cylindrical gear 33 to rotate for a circle, then the two are disengaged, because the upper and lower ends of the cam 14 are both convex ends, the piston 16 can be driven to slide back and forth twice by the rotation of the cam 14, the artificial respiration can be carried out on a patient twice, and the requirements of 30:2 of the ratio of cardiac compression to artificial respiration during cardio-pulmonary resuscitation in medicine are met;

after carrying out once cardiopulmonary resuscitation, medical personnel can observe the state of patient this moment, when the patient resumes heartbeat and breathing, can close motor 23, then open U-shaped plate 2 through extrusion fixture block 20 can, when patient's heartbeat still does not resume with breathing, can make motor 23 continue to rotate, supporting disk 13 drives arc 30 anticlockwise rotation and breaks away from the contact with movable block 28, movable block 28 slides right under the effect of pressure spring, movable block 28 drives compression leg 29 and moves right and make the spherical bulge on two driving plates 26 contact, motor 23 output begins to drive sleeve 25 and rotates, the pressure pad begins to press patient's heart, it carries out cardiopulmonary resuscitation to last the patient, it can to resume heartbeat and breathing until the patient, close motor 23 and open U-shaped plate 2.

The heart-lung resuscitation device is novel in concept, ingenious in structure, convenient to operate and high in practicability, the arranged rectangular frame and the arranged pressure lever can replace hands of medical workers to press the chest cavity of a patient, the working strength of the medical workers is reduced, precious time is saved for the medical workers, the arranged cam and the arranged piston can replace the medical workers to perform artificial respiration on the patient, heart pressing and artificial respiration are performed alternately, the efficiency of the heart-lung resuscitation is improved, the arranged rotary disc and the plurality of fixed blocks enable the ratio of the heart pressing and the artificial respiration to meet the medical requirements, and the effect of the heart-lung resuscitation is enhanced.

Therefore, the emergency cardiopulmonary resuscitation device provided by the invention can effectively solve the problems of time and labor waste when medical workers in the current emergency department perform cardiopulmonary resuscitation on patients, is simple in structure operation and convenient to use, and improves the efficiency of cardiopulmonary resuscitation.
