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.

Abstract: A therapeutic device comprising, a sleeve for covering a portion of a patient's body and having flexible walls defining an inner space to receive liquid, a conduit system connected to the space, and a device for circulating a liquid through the conduit system and the sleeve space. The therapeutic device has a device for changing the temperature of the circulating liquid in the conduit system, and a device for pressurizing the liquid in the sleeve space.

Abstract: A folded drape comprising, a sheet of flexible material including a first surface for contacting the body of a patient after placement of the drape, and an opposed second surface. The sheet has first and second spaced lateral fold lines defining a central panel having a fenestration located adjacent a lateral central portion thereof, and a third lateral fold line located intermediate the central panel and one end edge of the sheet, with the third fold line defining an end panel intermediate the one end edge and the third fold line, and with the first fold line being located intermediate the second and third fold lines.
