Abstract: Apparatus and method for preventing photosensitive epilepsy in a user includes positioning light sources in front of the users eyes so that light from the light sources is directed toward the user's peripheral visual field of view. The light reduces the intensity difference between light received by the peripheral visual field of view and light received by the central visual field of view.

Abstract: A device for piercing the skin to obtain a blood sample includes a sleeve which has an open first end and a cavity. A piercer is disposed within the cavity, and has a tip which is positioned near the open first end of the sleeve. The user applies opposing finger pressure to the device so that the skin of one finger enters the cavity and is pierced by the piercer. During this operation the piercer does not move with respect to the sleeve.

Abstract: A device for improving the early detection of a malignant breast cancer tumor in the breast of a human being includes a foreign body implant which is shaped and dimensioned to imitate a breast tumor. The foreign body implant is implanted in the breast of a human being and provides a tactile standard with which to compare a possible actual breast cancer tumor. During periodic breast self examination, the human being feels the foreign body implant to reinforce a tactile memory of what breast tumors feel like.

Abstract: A test tube insert includes a flange having a width greater than a width of a mouth of a larger test tube into which the insert is to be inserted. The flange defines a first central opening. An annulus extends integrally downward from the flange. The annulus includes a fenestrated wall and a floor defining a second central opening. A small test tube body, smaller than the larger test tube, extends integrally downward from the floor of the annulus with the second central opening forming a mouth of the small test tube body. The test tube insert is disposed in the mouth of the larger test tube. Fluid is transferred through the central opening and the fluid fills the small test tube body of the test tube insert and flows through the fenestrated wall once the small test tube body is full into the larger test tube.

Abstract: A trocarless intravenous cannula with a multifilament tip is described. The trocarless intravenous cannula has a tapered, distal multifilament tip that is comprised of a plurality of individual filaments. In one aspect, the distal part of the cannula is fenestrated. The tip and the distal part of the cannula may both be covered in a dry, water-soluble coating.
