EFFECTIVELY-SUPPORT-TYPE OXYGEN INHALATION AND SPUTUM ASPIRATION OROPHARYNGEAL AIRWAY DEVICE

摘要

An effectively-support-type oxygen inhalation and sputum aspiration oropharyngeal airway device, relating to the technical field of medical instruments, solving the technical problem that existing oropharyngeal airway devices have an adverse stimulation effect which easily causes complications imperiling a patient's life, and integrating sputum aspiration and oxygen inhalation structures and functions and improving the efficiency of the device. The effectively-support-type oxygen inhalation and sputum aspiration oropharyngeal airway device, comprising an inner airway body (11) provided from a proximal end to a distal end, and a support plate (10) parallel to the human tongue surface and having a certain width; the support plate (10) comprises a proximal end (101) and a distal bending portion (102), the proximal end (101) being positioned on the front face of the inner airway body (11) and constituting the wall of a duct, and the bending angle of the distal bending portion (102) being 0° to 180°; the front face of the distal bending portion (102) is provided with at least two evenly distributed projections (402), or recesses (403), or through holes (401); the surfaces of the projections (402) facing to the teeth are smooth and the surfaces of the projections (402) facing to the pharynx have a height of 1 mm to 2 mm, or the recessing depth of the recesses (403) is 0.5 mm to 1 mm, or the diameter of the through holes (401) is 1 mm to 3 mm; the inner airway body (11) provided from a proximal end to a distal end integrates a sputum aspiration duct and an oxygen inhalation duct.
