A device for endotracheal intubation based on magnetorheological fluid

Abstract

The invention discloses a trachea intubation device based on a magneto-rheological fluid. The device comprises a trachea intubation device body, a control box, a display, a piece of human-machine interaction equipment, an operating bed and a magnetic field generator, wherein the magnetic field generator is disposed on the operating bed; an air cylinder, a gas supply control valve, a gas heater, a gas pressure and flow monitoring component, a hydraulic cylinder, a liquid supply control valve, a liquid heater, a liquid pressure and flow monitoring component, a pneumatic triple linkage part, a controller and a power source used for power supply are disposed in the control box; the display and the human-machine interaction equipment are installed outside the control box; and the trachea intubation device body is composed of a visual probe, a visual probe data line, a film trachea catheter, a film trachea catheter connector, a gas supply connector and a liquid supply connector. The trachea intubation device based on the magneto-rheological fluid disclosed by the invention has the advantages that the use cost is low; the structure is compact; the problem of trachea intubation of an anatomic variation patient can be solved; trachea intubation duration can be shortened; trachea intubation courses can be simplified; and risks in the patient's trachea intubation can be reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular a tracheal intubation device based on magnetorheological fluid. Background technique [0002] During the operation, doctors need to intubate the trachea of ​​seriously ill patients. Since the tracheal tubes currently used clinically are all standardized tracheal tubes, when encountering patients with congenital airway anatomical variation or airway variation caused by other disease states, it will increase the difficulty of tracheal intubation, prolong the time of tracheal intubation or even fail , is likely to cause hypoxia and endanger the patient's life. However, if a thinner endotracheal tube is used, it will lead to insufficient oxygen supply and affect the postoperative recovery of the patient. [0003] The standard endotracheal tube will be thinner than the patient's trachea, and cannot be effectively fitted on the patient's airway mucosa, leaving a gap. During the operation...

Problems solved by technology

[0004] The standard endotracheal tube is soft, even if its diameter is increased, it cannot effectively solve the problem of reflux of the patient's stomach contents into the patient's trachea
