  • Patent number: 4623328
    Abstract: A preferred patient blood treatment system for the photoactivation of reagents in contact with a patient's blood employs an infusion pump for adding anti-coagulation reagent to the blood during extracorporeal operations. The infusion pump is preferably driven by a stepper motor and monitored by a periodic photo chopper employing a plurality of sensors. The spacing of the sensors and the spacing of the photo choppers work in concert to detect rotation of the stepper motor and to discriminate such from stutter or other characteristic nonrotational faults associated with stepper motors.

  • Patent number: 4619617
    Abstract: The invention distinguishes between two aspects of learning the technique of cardio-pulmonary resuscitation. One aspect is in learning what CPR feels like. The other is in learning the sequence of actions, times, rates, etc. It is the latter aspect that is more easily forgotten, and the invention provides a very inexpensive aid, which has the simplest possible mouth and chest simulators. The student can carry out a periodic repetition of the routine of motions on the aid. Refresher courses are then not needed so often, and the courses can concentrate on the "feel" aspects of CPR rather than the "routine" aspects. A simple and inexpensive teaching and practice aid for CPR is provided which has a stand on which a piece of foam material is mounted, and a generally self-supporting tube which has an upwardly facing open end. The other end of the tube is connected to a balloon. The structure and action of the device more or less replicates the physiology of a person in cardio-pulmonary arrest.

  • Patent number: 4614499
    Abstract: A simulator, for use with stereoradiographs, as a neurosurgical aid in locating potential paths for the implantation of probes in selected locations of the brain. It has a support, on the top surface of which is mounted a pair of radiographs disposed for stereoscopic viewing. An elongated ruler lies over the stereoradiographs and is movable in translation over them. A pair of transparent flat plotting plates are mounted on the ruler and are slidable therealong. Each plotting plate has a circular hole and a transparent circular disc is rotatable around this hole; a radial line extending from the center of the disc giving a "floating line" in the stereoscopically viewed model to simulate a probe to be implanted in the brain.

  • Patent number: 4611998
    Abstract: An infant-sized mannequin is provided for use in training or practicing cardiopulmonary resuscitation involving synchronized insufflation and external cardiac massage manipulations. The mannequin is provided with lung-simulating structure, including a pressure switch transducer actuated by insufflations applied to the mannequin and producing an electrical signal indicative of the rate and pressure of the applied insufflations. The mannequin is also provided with a plunger mechanism actuatable by cardiac massage manipulations applied to the mannequin. The plunger mechanism in turn actuates a potentiometer transducer which produces an electrical signal indicative of the rate and depth of cardiac massage. The electrical signals are conveyed by wire connections to a recorder producing separate record traces of cardiac massage action and insufflation, for providing a visual record of the several CPR parameters indicative of the performance skill of one performing CPR on the mannequin.

  • Patent number: 4609356
    Abstract: An educational toy comprises a tray (12, 14) having a plurality of templates (16) positioned thereon in a rearrangeable pattern. Each template has a hole therethrough of a unique shape. A corresponding plurality of mating male forms (20) are provided. The toy is used by placing the forms into their mating templates. Upon placement of a form into its mating template, a magnet (30) in the base of the form becomes positioned close enough to close a reed switch (32) under the tray. Closure of the reed switch activates a timing circuit (FIG. 7) which activates a moving, sounding toy (22) for a brief interval, thereby indicating to the child that he or she has made a correct placement. The templates can be easily rearranged in many patterns on the tray so that the child will not get bored with the game.

  • Patent number: 4607847
    Abstract: A game derived from tick-tack-toe, and a gameboard and game pieces for playing the game. The gameboard is square, with a grid of sixteen square locations to receive game pieces. For two players, a cover is placed over seven of the locations to leave a grid of nine, and for three or four players all sixteen locations are used. The game pieces are octagonal and are placed for movement along the grid or diagonally to the grid. Pieces are placed in turn to attempt to place three in a contiguous line. When all pieces have been placed and no player has won, the pieces are moved within the grid in an effort to win. A piece must be moved in the direction set when the piece was placed, but the piece can be changed during a move, or the direction can be changed as one player's turn.

  • Patent number: 4607848
    Abstract: A word game played for amusement involving the guessing of concealed words through definitional and phonetic clues. The outcome of a roll of die or other randomness means determines the set of definitional clues and single phonetic clues the player is to use. When the words are properly guessed, the player covers a score board space corresponding to the random number. As play progresses, the score board spaces become full and influence strategy. The first player to fill their score board wins.

  • Patent number: 4607849
    Abstract: A jet exhaust simulator provides a multichamber jet fuel burner in which the fuel supplies to the chambers may be remotely and independently controlled, and in which a pilot flame chamber with squib igniter provides a reliable source of combustion. Primary, secondary, and tertiary fuel nozzles are provided, with the tertiary nozzles using straight venturis to inject large fuel drops into a burning fuel/air mixture in order to produce an exhaust plume closely simulating the length and infrared light emissions characteristics of a jet aircraft engine. The exhaust simulator is particularly adapted for use in a towable aerial target for the testing of infrared seeker guided shells or missles.

  • Patent number: 4605373
    Abstract: An artificial limb (e.g., leg) is provided with rigid members simulating the lower and upper halves of the lower leg, the knee joint and the upper leg. At each joint is a sensor-potentiometer similar to the joy-stick of a computer game arranged so that relative movement of rigid members cause movement of the joy-stick. Leads from the outputs of the sensors are connected to an analog-to-digital converter connected to a personal computer. In teaching first aid for fractured limbs, the student is taught to apply splints and move the patient to a stretcher with as little relative movement as possible. The training device indicates relative movement. The screen may display positions of the rigid members in two planes and/or numerical tallies.

  • Patent number: 4604061
    Abstract: A display rack and color selector assembly adapted to present to a homeowner a group of sample boards carrying actual roof shingles in a variety of colors and to afford a visual picture of a typical home whose architectural style is similar to that of the homeowner, the roof of the pictured home being selectively covered by a shingled surface in any one of the sample colors. The color selector includes a front panel on whose face is a radial array of pictures of typical homes in different architectural style, the roof in each picture being notched out to define a window whose geometry matches that of the roof. Mounted behind the panel is a rotatable color wheel which is divided into segments each having a shingled surface whose color corresponds to that of a respective sample in the group.

  • Patent number: 4601665
    Abstract: A cardiovascular examination training aid includes a mannikin with a flexible wall animated by a group of electromechanical linear transducers which are energized in accordance with the program in a selected ROM cartridge of a group and whose output is timed by a variable frequency clock and corresponds to a desired cardiovascular condition. Also controlled by the selected cartridge program is a pulse or heart sound produced in a stethoscope in accordance with the area of application of the stethoscope and the program in the selected cartridge. Blood pressure is measured by producing a pulse audio signal for the brachial artery region and applying a pressure cuff to the region and applying the signal to the stethoscope only when the cuff pressure is within a range established by the cartridge program.
