Abstract: An ultrasound acoustical coupling pad comprising, a retaining member comprising a sheet having a front surface, a back surface, and a cut-out. The pad has a doppler transducer received in the cut-out, and a strip of acoustical gel covering at least a substantial portion of the front surface of the retaining member. The pad has a backing member comprising a sheet secured to the retaining member and having an edge portion extending outwardly from the retaining member and strip, with the edge portion having adhesive on a front surface thereof to secure the pad to the skin of a patient.

Abstract: A temperature, pulse and respiration probe having a mouthpiece which fits over the patient's teeth and carries a thermistor for sensing the patient's temperature and a reflective photodetector for sensing both the patient's pulse and the patient's respiration. The reflective photodetector is mounted adjacent to a part of the interior surface of the patient's mouth which relatively rapidly, periodically changes its reflectivity due to the patient's pulse and which also relatively slowly, periodically changes its reflectivity due to the patient's respiration. The photodetector produces a single signal representative of both the relatively rapid and the relatively slower changes in the reflectivity corresponding to the patient's pulse and respiration rate, respectively. In one embodiment, all of these sensors are mounted to a portion of the mouthpiece adjacent the patient's inner gum. In another embodiment the sensors are mounted to a portion of the mouthpiece which underlies the patient's tongue.

Abstract: A sterile cover for an instrument comprising, a tray having an upright post, with the post having an upper end and a lower end. The cover has a sleeve of flexible material having an open end and a closed end. The sleeve is placed on the post with the closed end being located adjacent the upper end of the post, with the sleeve extending over the post from the upper end toward the lower end of the post, and with the open end of the sleeve being accessible to a user to remove the sleeve from the post.
