| Abstract: |
A looped cannula for administering oxygen and consisting of a flexible hollow tube having apertures disposed along a preselected midlength of the loop and at circumferentially spaced locations so that once the loop is encircled about the head of the patient and the loop is preferentially tightened, there will be a continuous stream of oxygen through at least some of the apertures directed toward the nose of the patient. The loop is held in operative position by means of a mounting member in the form of a fabric which is located at the crown of the head and has portions extending toward the anterior of the head and terminating in mounting sections. Substantially upright portions are operatively connected to the fabric and also to the loop, such upright members being located closely adjacent the ear and holding the loop in its appropriate location. Oxygen is continuously supplied to the loop through both of the open ends by means of a single oxygen supply line which is fitted into an adapter. The adapter receives the oxygen in a chamber and supplies the oxygen from the chamber to both of the open ends of the loop.

What is claimed is:
1. A looped oxygen cannula for distributing oxygen for inhalation: comprising a dual branched flexible tubular loop with each branch being hollow and forming an oxygen supply line one independent of the other and adapted to loop over the face and upper lip of the person intended to receive oxygen and conforming to the facial outline of the patient receiving such oxygen, said loop terminating at the rear of the person's head with both ends of the loop passing through a common opening, a choke member providing said opening for the loop ends and adapted to pass along the loop ends to adjust the size of the loop to conform with the outline of the person, oxygen supply means for providing an inflow of oxygen through each of the branches of said loop which are independently fed a continuous stream of oxygen in each such branch, said branches meeting in a frontal portion at the vicinity of the upper lip of the person and at the frontal area of the face, such frontal portion including a plurality of openings in the direct vicinity of the nose of the person and distributed both circumferentially and along the length of the cannula to provide at least some streams of oxygen directed toward the nasal passages of the person for direct inhalation, said oxygen supply means being disposed at the rear of the persons's head, support members disposed one at each of the opposite side faces of the person and operatively connected to respective branches to hold them in operative position, mounting means operatively secured to the head by conforming generally with the outline of the head to secure said mounting means to the skull of the user, said mounting means including support means adapted to extend downwardly along each respective side of the head and terminating approximately below the ear and at respective sides of the ear, the support members being connected to the support means at the respective sides of the head to support the branches, whereby the oxygen cannula is supported vertically in its operative position.
