Abstract: A medical mechanical controlled balance ventilation single-lumen lung isolation catheter bridging spans trachea to bronchus and by-pass flow gas holes of wall, which has a intraluminal main trachea tube and a distal intraluminal bronchus tube in communication with one end of the intraluminal main trachea tube; a first opening is provided at a rear end of the distal intraluminal bronchus tube; a second holes opening zone having at least two holes is provided at a side wall of a lower end of the intraluminal main trachea tube; the transmural holes of the second holes opening zone are distributed along a same or different horizontal sectional surface or vertical sectional surface of a three dimensional space formed inside the intraluminal main trachea tube.

Abstract: The present efficient support portable constant negative pressure suction apparatus for outdoor use includes: a negative pressure suction ball extending from the proximal end to the distal end, the negative pressure suction ball being provided with an internal sac structure; the internal sac structure includes: a round gas exhaust valve, a spherical sac, and an anti-reverse flow flap arranged in sequence from the proximal end to the distal end; and also including: a negative pressure suction tube, the negative pressure suction tube being in communication with the negative pressure suction ball and the negative pressure suction tube being provided with a suction control channel.

Abstract: An effectively-support-type oxygen inhalation and sputum aspiration oropharyngeal airway device, comprising an inner airway body provided from a proximal end to a distal end, and a support plate parallel tongue surface and having -a-certain width; the support plate comprises a proximal end positioned on the front face of inner airway body and constituting the wall of duct, and a distal bending portion with bending angle of 0°-180°; the front face of distal bending portion is provided with at least two evenly distributed projections, recesses, or through holes; the surfaces of the projections facing to teeth are smooth and the surfaces of facing to pharynx have a height of 1-2 mm, or the recessing depth of recesses is 0.5-1 mm, or the diameter of through holes is 1-3 mm; the inner airway body provided from a proximal end to a distal end integrates a sputum aspiration duct and an oxygen inhalation duct.
