  • Patent number: 6024723
    Abstract: A device is described for reminding a patient suffering from ailments such as diabetes and high cholesterol levels, who performs daily blood tests, of the site of the last blood extraction, in the case where blood is drawn from one or more sites of each finger of the hands. The invention includes two disks, each having an inner face and an outer face, the inner face containing a representation of the opposite hand from the other. On each disk finger holes are punched in the vicinity of the fingers to represent the sites where blood is drawn. On the inner face of each disk is a red marker area which may be displayed under the finger hole on the opposite disk, corresponding to the last site where blood was drawn. When the user progresses from one hand to the other in his testing regime, the device is flipped over, and the outside face of the other disk is used to display the status of the site where blood has been drawn on a representation of the hand currently used.

  • Patent number: 6024725
    Abstract: A sleeve for introducing a surgical instrument (e.g., a lipoplasty probe) into the body via a wound pierced in the skin, and an insertion device for making the wound and inserting the sleeve therethrough are provided. The sleeve reduces the transmission of friction and heat (e.g., caused by the highly repetitive in-and-out and rotational movements and ultrasonic vibration of the lipoplasty probe) to the skin of the patient. In addition, the size of the hole associated with insertion of the sleeve is significantly smaller and more uniform in shape than that associated with a traditional scalpel incision. By piercing the skin, rather than making an incision with a scalpel, and by reducing friction and heat transmission to the skin, the irritation, inflammation, flowering (i.e., curling up of the skin at the edges of an incision), and scarring associated with lipoplasty are minimized, and the cosmetic result of the procedure is improved.

  • Patent number: 6015438
    Abstract: A full displacement retractable syringe has a front mounted retraction mechanism and a plunger with a sliding seal and a retraction opening with a sliding stopper. A needle holder is held in place with a holding ring which seals the front part of the barrel from fluid leakage and forms the bottom of a variable chamber in the barrel. The top of the variable chamber is formed by the nose of the plunger with its sliding plunger seal and stopper. Substantially all of the fluid contained in the variable chamber is expelled through a needle when the plunger is depressed to bring the upper and lower boundaries of the fluid chamber together. Because the plunger seal is restrained from forward movement by a stop in the barrel, the nose of the plunger slides through the plunger seal to operate the retraction mechanism.
