Emergency percutaneous trans-tracheal high flow oxygen catheter-type resuscitator for restoration of breathing in non-breathing patients

Claim 1

A patient adaptor means comprising the combination of a ventilating apparatus and a tracheotomy instrument, said tracheotomy instrument including a catheter of plastic material which has a plastic memory and is fabricated in a curved shape, said catheter adapted to fit over the outside of a substantially straight needle and be straightened out by said needle when the needle is pushed through the catheter and penetrates into the trachea to have the catheter therein, said material causing the catheter to resume the original curved shape as a result of said plastic memory within the trachea after the needle is withdrawn therefrom, attachment means secured to said catheter near the outer end where the needle is totally withdrawn after the catheter has been inserted into the trachea, said attachment means adapting the catheter to be taped, tied or fastened to the neck, and a fluid fitting at said outer end connected to said ventilating apparatus, said ventilating apparatus comprising a pressurized source of oxygenated gas connected to a pressure conduit, a vacuum source connected to a suction conduit and an output conduit connected to said fluid fitting, valve means interconnecting said pressure, suction and output conduits, and passage means in said valve means to connect said pressure conduit to said output conduit and to disconnect said suction conduit from said output conduit to provide an inflation phase in one position and to connect said suction conduit to said output conduit and disconnect said pressure conduit from said output conduit to provide a deflation phase when said valve means are in a second position, said valve means comprising valve members cyclically operated by an air motor mechanically connected thereto, and a throttle valve connected to said motor to regulate the flow of control fluid thereto.
