Description

Technical Field

[0001] The present invention belongs to the technical field of anesthesia devices, and specifically refers to an anesthesia intubation assistance device. Background Art

[0002] Anesthesia intubation usually refers to tracheal intubation during general anesthesia surgery. This operation is mainly to keep the airway unobstructed when the patient is under anesthesia, prevent the progress of the surgery from being affected due to airway blockage, and ensure the patient's life safety. During general anesthesia, the patient is often in an unconscious state and unable to breathe independently, and the oxygen supply required by the body may not be met. Therefore, it is necessary to connect to a ventilator through tracheal intubation, and the ventilator assists in breathing to keep the airway unobstructed, so that the patient's surgical process is safer. In addition, tracheal intubation can also prevent gastrointestinal reflux and avoid airway blockage and patient hypoxia.

[0003] When existing doctors perform anesthesia intubation on patients, they usually first insert a laryngoscope into the patient's oral cavity and expose the patient's glottis through the laryngoscope. After the glottis is clearly exposed, the trachea is inserted. After confirming that the catheter position is correct, a bite block is placed between the patient's upper and lower teeth, and then the tracheal catheter and the bite block are properly fixed with adhesive tape or a tracheal catheter fixation device to prevent the catheter from shifting or slipping out. This process is cumbersome and requires high hand coordination of medical staff. Medical staff need to operate the laryngoscope with one hand to expose the glottis and insert the trachea with the other hand, and the hand is prone to soreness. Therefore, this application provides a clinical anesthesia intubation assistance device for the anesthesiology department to meet the needs. Summary of the Invention

[0033] The mounting bracket 3 is arranged in a U shape, and the spreading mechanism 4 includes a transverse sliding shaft 49, a transverse slider 50, a self-adjusting spring 51 and a support plate 52. The transverse sliding shaft 49 is arranged in the mounting bracket 3, and the transverse slider 50 is symmetrically slidably arranged on the transverse sliding shaft 49.

[0036] During specific use, first let the patient lie on the bed, then fix the device to the side of the bed through the clamping mechanism 1. Rotate the adjusting screw rod 81 by screwing the clamping knob 82. The adjusting screw rod 81 drives the upper clamping plate 77 to move up and down through the adjusting sleeve 80, so as to adjust the distance between the upper clamping plate 77 and the lower clamping plate 78, facilitating the fixed installation of the device on the side of the operating bed. The guiding telescopic rod 79 guides and limits the upper clamping plate 77 and the lower clamping plate 78. Then fix the laryngoscope in the fixed clamping device 27 and the adjustable clamping device 28. Pass the handle part of the laryngoscope into the clamping sleeve one 30 and the clamping sleeve two 39. Then rotate the clamping screw rod one 34 to drive the arc-shaped clamping plate one 35 to move downward in the clamping sleeve one 30, and rotate the clamping screw rod two 43 to drive the arc-shaped clamping plate two 44 to move up and down in the clamping sleeve two 39, thereby clamping and fixing the grip of the laryngoscope. Then assemble the bite tube 12. Thread the dental pad tube 18 and the limit ring seat 17 together and set them aside for later use. Then adjust the height and horizontal position of the device. Rotate the vertical adjusting knob 70 to drive the bevel gear one 66 to rotate. The bevel gear one 66 drives the vertical screw rod 63 to rotate through the bevel gear two 67. The vertical screw rod 63 drives the vertical sliding part 64 to slide up and down along the vertical slide rod 65 and the vertical screw rod 63 through the vertical screw hole 69, adjusting the height of the top plate 60 to adapt to patients with different head circumferences. Rotate the horizontal adjusting knob 76 to drive the horizontal rotating shaft 75 to rotate. The horizontal rotating shaft 75 drives the horizontal screw rod 73 to rotate. The horizontal screw rod 73 drives the horizontal sliding plate 72 to move horizontally along the horizontal sliding sleeve 71 through the horizontal screw hole 74, thereby adjusting the horizontal position of the U-shaped fitting plate 5. When the bottom wall of the U-shaped fitting plate 5 fits the patient's face and the self-adjusting intubation positioning mechanism 6 is directly above the mouth, stop adjusting the height adjusting frame 59 and the horizontal adjusting frame 61. Then control the first electric push rod 24 to contract through the control button one, thereby driving the Z-shaped bracket 25 to move downward. The Z-shaped bracket 25 drives the laryngoscope to move downward and insert between the two support plates 52 through the mounting plate 26 and the fixed clamping device 27 and the adjustable fixed clamping device 27 provided on the mounting plate 26. The support plates 52 drive the two horizontal sliders 50 to slide and separate along the horizontal slide shaft 49 through the connecting rod 53, and compress the self-adjusting spring 51 to deform. The arc-shaped transition part 55 facilitates inserting the laryngoscope between the two support plates 52, thereby facilitating opening the patient's oral cavity. When the laryngoscope is inserted into the patient's epiglottis, control the first electric push rod 24 to stop moving, and control the second electric push rod 37 to move upward through the control key two 48. Drive the adjusting U-shaped frame 38 and the clamping sleeve two 39 to move upward through the second electric push rod 37. The clamping sleeve one 30 and the clamping sleeve two 39 automatically rotate to always maintain a coaxial setting. Through the mutual cooperation of the second electric push rod 37, the clamping sleeve one 30 and the clamping sleeve two 39, the laryngoscope can be obliquely lifted, facilitating the complete exposure of the glottis and facilitating the fixation of the laryngoscope, making it more convenient for medical staff during intubation. When the two support plates 52 separate, they drive the two connecting rods 53 to separate. The two connecting rods 53 pull the first hinge rod 56 and the second hinge rod 57 to rotate downward synchronously.Thereby driving the hinge shaft 58 to move downward, the first hinge rod 56 and the second hinge rod 57 ensure that the hinge shaft 58 is always in the exact middle of the two connecting rods 53. The hinge shaft 58 drives the self-adjusting intubation positioning mechanism 6 through the limit slider and the limit sliding frame 10, so that the self-adjusting intubation positioning mechanism 6 slides along the width direction of the U-shaped fitting plate 5 to ensure that the distances between the self-adjusting intubation positioning mechanism 6 and the two support plates 52 are always equal. Then, tracheal intubation is performed. The assembled bite tube 12 is inserted from above the positioning ring seat 11. The cam 15 enables the bite tube 12 to only move downward, and when moving upward, the resistance is large and it is difficult to move. After inserting the bite tube 12 into the patient's mouth, then pass the trachea through the bite tube 12 and perform intubation. After the intubation is completed, inflate the limit airbag 19 through the inflation nozzle 21, so that the limit airbag 19 inflates and bulges to fix the trachea. With the help of the cam 15 and the limit airbag 19, double fixation of the trachea is achieved. Then, control the second electric push rod 37 and the first electric push rod 24 to move in the reverse direction and reset, thereby driving the laryngoscope to be pulled out of the patient's mouth. The self-adjusting spring 51 drives the transverse sliders 50 to move closer to each other. The transverse sliders 50 drive the support plates 52 to fit together through the connecting rods 53, releasing the expansion of the patient's oral cavity. At this time, the patient's teeth bite on the bite tube 12. When extubation is required, deflate through the control valve 22, so that the limit airbag 19 deflates and shrinks, releasing the limit on the trachea, and then perform the extubation operation. Then, adjust the height of the height adjustment frame 59 to rise, drive the U-shaped fitting plate 5 to move upward, and drive the bite tube 12 to be pulled out of the patient's mouth. Then, unscrew and separate the dental pad tube 18 and the limit ring seat 17, and the dental pad tube 18 can be pulled out downward from inside the positioning ring seat 11.,
