Patent number: 7806852Abstract: An apparatus and associated methods are provided to authenticate a patient based on a biometric identifier of the patient before a prescribed dose of medical therapeutic, such as analgesics or other medication, are dispensed to the patient. Authentication takes places by pressing a button and scanning the patient's fingerprint and recording data corresponding to the fingerprint into memory. To receive the medical therapeutic, the patient can have his or her fingerprint read and compared to the stored fingerprint. If there is a match and the programmed limitations are met (e.g., a time interval has elapsed since the last dose), then the medical therapeutic is automatically dispensed to the patient. The system may be integrated with a new patient-controlled medical therapeutic device or the system may be added to an already existing device. Other features and advantages of the example embodiments are described.Type: GrantFiled: April 3, 2006Date of Patent: October 5, 2010Inventor: Phillip A. Jurson

Patent number: 7785295Abstract: A medical line securement device holds a medical article such as a connector fitting for a catheter or a catheter adaptor in position upon the body of a patient and inhibits axial motion of the medical article. The securement device includes a retainer with a base and a cover. The cover is hinged to the base such that it may be moved between an open and closed position. The base and cover each have a groove which cooperate when the cover is in the closed position to form a channel through the retainer. The medical article includes an elongated body which is received within the groove of the retainer, the elongated body lying between at least a pair of regions of larger radius of the medical article. By receiving the portion of the elongated body of the medical article between the regions of larger radius, axial motion of the medical article through the groove is inhibited. The retainer may also include one or more slots to receive any radial projections of the medical article within the retainer.Type: GrantFiled: August 10, 2007Date of Patent: August 31, 2010Assignee: Venetec International, Inc.Inventor: Steven F.
