  • Patent number: 4911688
    Abstract: A clear cover to be placed on the skin of the human body to surrond a wound on the skin (14), and to hold fluid (21) in contact with the wound. The cover has a flat, thin, flexible ring (1); the underside of which has an adhesive coating (7) to hold the ring on the body (14). A raised chamber (2) is formed by a thin flexible wall extending up from the ring (1), which has nipples (3) for being pierced by hypodermic needles (16); for filling the chamber (2) with fluid (21), and for venting air out of the chamber when the chamber is receiving fluid.The above fluid containing cover having means to create free ions and an electrical field to enhance healing and regeneration of tissue; including a voltage source (10), a series resistance (11), and a metallic anode (12).

  • Patent number: 4896085
    Abstract: A silent, high torque, impulse actuator system for low average power devices. The system incorporates a typical small three pole D.C. motor which has been modified to allow quick electrical conversion, with unipolar switching circuitry, from conventional rotation, to silent magnetic braking at a stop position; and then to a normally OFF condition.The high efficiency of this intermittent drive system is enhanced by the unique combination of being normally off between actuations; the high efficiency of the D.C. motor during start conditions; and the use of a round cam to provide a cosine power stroke that utilizes the inertia of the motor rotor to maximum mechanical advantage.

  • Patent number: 4732151
    Abstract: For use in suturing: (a) Thin steel needle put into flesh (using a tool) on one side of the wound until anchor fixed to a needle engages flesh. At that time point of needle will protrude. Anchor crimped on the protruding side; (b) Anchors are in ball form with square cavities to accept projections on hand tool; (c) Plier-like tool used to grab anchors has projection which fits into anchor cavities; (d) dispenser for needle/anchor assembly and dispenser for crimp-on anchor provide for quick removal in sterilized condition.

  • Patent number: 4685912
    Abstract: A flexible tube is mounted on top of the drip chamber. The top of the tube is connected to the spike via a one-way ball-type valve. The bottom of the tube is connected to the drip chamber via a duck-bill-type valve inside of the drip chamber. The duck-bill is held closed against head pressure by a metal spring clip acting on the lip. The duck-bill will open when the tube is squeezed and fluid will be injected into the drip chamber.The drip chamber is charged bubble-free by the use of an output tube open to the chamber and joined to the flexible tubing carrying the hypodermic needle. During the initial fill the output tube is positioned above the fluid level and air in the chamber vented via the output tube, the flexible tubing and the hypodermic needle. When the desired level is reached, the output tube is submerged and bubble-free fluid fills the output tube, the flexible tubing, and the hypodermic needle.
