  • Patent number: 8658193
    Abstract: Technologies are described herein for styptic compounds comprising a hemostatic or styptic agent suspended within a hydrophobic carrier medium. Example carrier mediums may include waxes, lipids, oils, or combinations thereof. The compound may be a semisolid at room temperature and soft enough to be easily dispensed and formed into or onto bleeding tissue of an animal or human. The hydrophobic qualities of the carrier medium can protect the styptic agent from absorbing moisture. The carrier medium can mechanically support positioning treatments adjacent to the bleeding tissue. The carrier medium can further serve to mechanically seal the tissue to aid in hemostasis while also protecting the tissue from debris and contamination. The carrier medium can aid in maintaining moisture within the tissue. Slurry-based manufacturing processes can support a substantially homogeneous dispersal of styptic agent throughout the carrier medium.

  • Patent number: 8529469
    Abstract: A method for conducting a fecal examination includes providing a collection spoon and a collection container comprising a transparent body having a cap which can be removed to permit fecal matter to be received in the collection container with the spoon to be mixed with a flotation material to aid in separating the fecal matter and ova or eggs of parasites that may be contained in the fecal matter and then dispensed through a filter mounted in the cap of the collection container to a test tube and a cover slip on the test tube for examination of the filtered material for the presence of the ova of parasites.

  • Publication number: 20100168613
    Abstract: A fecal examination preparation receptacle comprising a plastic transparent body having a cap which can be removed to permit fecal matter to be received in the receptacle to be mixed with a flotation material to aid in separating the fecal matter and ova or eggs of parasites that may be contained in the fecal matter and then dispensed through a filter mounted in the cap of the receptacle for examination of the filtered material for the presence of the ova of parasites.

  • Patent number: 5456094
    Abstract: An earring assembly in which the earring has a post to pass through a pierced opening in the earlobe of a wearer to receive a clasp to hold the earring securely in position with the clasp being formed of plastic material with a head to be located behind the ear lobe of the wearer and a tubular sleeve projecting from the head to be located within the pierced opening in the ear lobe and receiving the post to completely isolate the earring from the flesh of the wearer and to limit the spacing of the earring ornament and clasp to avoid pressure on the ear lobe. The clasp is easily cut with readily available tools for modification to accommodate the thickness of the wearers ear lobes and the positioning of adjacent earrings.

  • Patent number: 4293405
    Abstract: A fecal examining device comprising a closure member in the form of a tray adapted to be fitted upon the open lower end of a solution-receiving receptacle or cylinder, said closure member or tray including a central, open-top cup that extends into the cylinder for a short, predetermined distance. A cap is provided for closing the open top of the cup or well when the tray is not attached to the cylinder. A perforated piston is provided for manual movement within the cylinder to thereby separate ova from the fecal material in solution.
