Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an emergency cardio-cerebral-pulmonary resuscitation device. Background Art

[0002] In the process of treating patients with cardiac arrest, it is necessary to press the patient's chest and perform cardiopulmonary resuscitation on the patient. If not rescued in time, it may cause death. When treating patients outside the hospital, personnel with certain first aid knowledge are required to perform chest compressions on the patient until the ambulance arrives.

[0003] The patent of Chinese patent publication number CN111714358A discloses an emergency internal medicine cardio-cerebral-pulmonary resuscitation rescue device, including a medical bed, and brackets are fixed on both sides of the medical bed by bolts. In the present invention, the rubber support pad can be moved upward by driving the motor to lift the patient's neck, which is convenient for medical staff to deal with foreign bodies in the patient's respiratory tract. The horizontal electric telescopic rod can drive the clamp to fix the patient's head to prevent the patient's head from shaking during emergency. At the same time, the rubber pressure pad can be fitted with the patient's chest by twisting the hand plate, and the patient's chest can be continuously pressed by the vertical electric telescopic rod, which saves the physical strength of medical staff and can also grasp the rhythm of pressing. However, due to the difference in patient size, the device cannot quickly adjust the pressing amplitude, which makes the device easy to cause danger to the patient when in use, or cause the pressing to be inadequate. At the same time, in the emergency process, every second counts. The device cannot be quickly installed and disassembled, which will affect the subsequent treatment and the use of other medical equipment. Summary of the invention

One end of the quick-release component 4031 is arranged inside the slot 4032, and the other end of the quick-release component 4031 is connected to one end of the connecting rod 404. By installing the quick-release component 4031 in different slots 4032, the distance between the quick-release component 4031 and the support seat 401 is controlled, thereby controlling the range of up and down movement of the buffer component 405, thereby adjusting the pressing arc according to the body shape of different patients, preventing the patient from being injured by excessive pressing, and reducing the possibility of secondary injury to the patient.

During installation, by pressing the pressing column 40318, the sliding rod 40316 compresses the spring 2 40317, and drives the connecting plate 40315 to the rear side away from the fixed column 40311, so that the connecting plate 40313 pulls the block 40314. The card block 40314 is hidden in the hidden groove 40312, and then the fixing column 40311 is inserted into the corresponding card slot 4032. Finally, the pressing column 40318 is released, and the spring 2 40317 drives the connecting plate 40315 to reset, so that the connecting plate 40313 makes the card block 40314 bulge through the torsion spring, and makes the card block 40314 stuck in the installation hole 4033, so that the connecting rod 404 is connected to the crank 402. When disassembling, just repeat the above actions. The installation and disassembly are very quick and convenient.

[0032] The buffer assembly 405 includes an outer sleeve 4051, an inner connecting rod 4052, a sliding column 4053 and a spring three 4054. The upper end of the sliding column 4053 is fixedly connected to the lower end of the inner connecting rod 4052, and the outer periphery of the sliding column 4053 is slidably connected to the inside of the outer sleeve 4051. The spring three 4054 is arranged on the inner bottom wall of the outer sleeve 4051, and the spring three 4054 is arranged at the lower part of the sliding column 4053. The lower end of the outer sleeve 4051 is fixedly connected to the middle part of the pressing plate 406, the outer periphery of the inner connecting rod 4052 is slidably connected to the middle part of the limiting sleeve 407, and the upper end of the inner connecting rod 4052 is rotatably connected to the end of the connecting rod 404 away from the crank 402. When the pressing plate 406 is pressed on the patient's ribs, the sliding column 4053 will slide inside the outer sleeve 4051 and compress the spring three 4054 at the same time, thereby being able to provide a certain degree of buffering and reducing the possibility of secondary injury to the patient.

[0033] The connecting mechanism 3 includes a fixed sleeve 301, a partition 302, two latches 303, two springs 1 304, two shift blocks 305, two connecting sleeves 306, two connecting columns 307 and a mounting plate 308. The outer periphery of the partition 302 is fixedly connected to the middle of the fixed sleeve 301, and the outer periphery of one end of the latch 303 is slidably connected to the inside of the front and rear sides of the fixed sleeve 301. The spring 1 304 is arranged between the partition 302 and the latch 303. One end of the shift block 305 is fixedly connected to the outer periphery of the latch 303. The lower part of the connecting sleeve 306 is fixedly connected to one end of the connecting column 307, and the other end of the connecting column 307 is fixedly connected to the front and rear sides of the mounting plate 308. The mounting plate 308 is installed on the left and right sides of the bed. By pressing the two shift blocks 305 inward, the pin 303 compresses the spring 1 304 and moves toward the partition 302, so that the pin 303 is removed from the inside of the connecting sleeve 306, so that the support frame 1 can be quickly removed from the bed, which is convenient for subsequent treatment and the use of other medical equipment.

[0034] The outer periphery of the latch 303 is arranged inside the connecting sleeve 306. By pressing the two shift blocks 305 inward, the latch 303 compresses the spring 1 304 and moves toward the partition 302, and then the latch 303 is aligned with the connecting sleeve 306. After releasing the shift block 305, the spring 1 304 drives the latch 303 to reset, so that the latch 303 is inserted into the connecting sleeve 306, so that the support frame 1 can be quickly installed on the bed for easy use.

[0035] Working principle:

[0036] By pressing the two shifting blocks 305 inward, the latch 303 compresses the spring 1 304 and moves toward the partition 302, and then the latch 303 is aligned with the connecting sleeve 306. After releasing the shifting block 305, the spring 1 304 drives the latch 303 to reset, so that the latch 303 is inserted into the connecting sleeve 306, so that the support frame 1 can be quickly installed on the bed for easy use. By pressing the pressing column 40318, the sliding rod 40316 compresses the spring 2 40 317, and drives the connecting plate 40315 to the rear side away from the fixing column 40311, so that the connecting plate 40313 pulls the block 40314, and the block 40314 is hidden in the hidden groove 40312, and then the fixing column 40311 is inserted into the corresponding slot 4032, and finally the pressing column 40318 is released, and the spring 40317 drives the connecting plate 40315 to reset, so that the connecting plate 40313 makes the block 40314 bulge through the torsion spring, and The card block 40314 is stuck in the mounting hole 4033, thereby connecting the connecting rod 404 with the crank 402, thereby controlling the distance between the quick-release assembly 4031 and the support seat 401, thereby controlling the range of up and down movement of the buffer assembly 405, thereby adjusting the pressing arc according to the body shape of different patients, preventing the pressing amplitude from being too large to injure the patient, and reducing the possibility of secondary injury to the patient. The buffer assembly 405 is restricted by the limit sleeve 407 so that the buffer assembly 405 can only move up and down vertically, driving the reduction motor 408 to rotate the crank 402, thereby driving the buffer assembly 405 up and down through the connecting rod 404, and then the patient's heart can be compressed for a long time, reducing the doctor's physical strength. When the pressing plate 406 is pressed on the patient's ribs, the sliding column 4053 will slide inside the outer sleeve 4051 and compress the spring three 4054 at the same time, so that a certain degree of buffering can be performed to reduce the possibility of secondary injury to the patient. When disassembling, the reverse operation can be performed.
