Title: Implantable cardiac function monitor and stimulator for diagnosis and therapy delivery
Inventor: SALO RODNEY W
IPC: A61M5/172
Filed: 1992-11-03
Abstract: An implantable monitor/stimulator is disclosed that monitors and assesses indices of cardiac function, including the strength and timing of cardiac contraction, then automatically executes a physician-selected mode of therapy. It accomplishes this by assessing impedance, electrocardiogram, and/or pressure measurements, then calculating various cardiac parameters. The results of these calculations may be stored within the device, telemetered to an external monitor or display and/or may be used by the physician to determine the mode of therapy to be chosen. If indicated, therapy is administered by the device itself or by telemetering control signals to various peripheral devices for the purpose of enhancing either contraction or relaxation of the heart.      The cardiac parameters that are calculated all provide an assessment of level of cardiac function by monitoring changes in ventricular filling and ejection or by calculating isovolumic phase indices of heart contraction. Examples of such parameters are ejection fraction, cardiac output, stroke work, and/or various pressure-volume relationships. These parameters determine the mode of therapy that will be selected by a physician. Choices of therapy include several forms of pacing of cardiac or skeletal muscle, and telemetry to implanted or external units for drug infusion or for monitoring by a central data system.

Title: Storage bag for blood and blood components
Inventor: HARMS FRANK H
IPC: F25D25/00
Filed: 1991-05-09
Abstract: IMPROVED STORAGE BAG FOR BLOOD AND BLOOD COMPONENTS            ABSTRACT           A bag (10) is disclosed for the collection, freezing, storage, and rapid thawing of fluids, and particularly blood and blood components.  Front and back sheets (11,12) of fluid impervious material are bonded to one another along edge portions (14) thereof, to form a bag (10), defining a reservoir.  The front and back sheets (11,12) are further bonded together at a plurality of locations (60) intermediate the edge portions (14) to constrain the distance by which the front and back sheets can separate.  The intermediate fastening locations (60) are disposed to permit uniform filling of the reservoir.  A port (30) is provided for introducing a discharging fluid into and out of the reservoir.  When a fluid is introduced into the reservoir, the front and back sheets (11,12) are constrained from separating in response to a pressure exerted by the fluid by the intermediate fastenings (60) between the front and back sheets (11,12) to constrain the thickness of the bag (10).  The distance between the centermost points in the interior of the bag and the corresponding closest points on the exterior of the bag is thereby minimized, increasing the rate at which it is transferred into or out of the bag contents.  Heat transfer is thus greatly improved, markedly reducing the time required to freeze or thaw the bag contents.

Les distances minimale et maximale possibles des objets (A, B, C) sur les lignes de visée (18a, 18b, 18c) du premier capteur (14) sont prédéterminées et utilisées pour calculer des « lignes de direction » (24, 26, 28) qui coïncident avec les ligne de visée (18a, 18b, 18c) et qui vont de la distance minimale à la distance maximale dans chaque cas. Ces lignes de direction (24, 26, 28) sont transposées dans le champ de vision du second capteur (16) et sont adaptées aux coordonnées d'azimut et de site des objets individuels (A, B, C) à l'aide d'un algorithme de résolution élémentaire (algorithme glouton) ou d'un algorithme à optimisation globale.

Abstract: A polymeric device and method for the control of insects on animals is disclosed.  The device is in the form of an ear tag or other shape which can be attached to an animal using known techniques.  A unique polymer/insecticidal formulation is provided by combining an ectoparasiticidal active compound, preferably an organophosphate, with a polyurethane polymer.  The polymer is the reaction  product  of  4,4'-diphenylmethane  diisocyanate, polytetramethylene glycol and 1,4-butanediol.  By utilizing the particular polymers described, high loadings of insecticides are possible and the resulting product shows no tendency to exude insecticide during prolonged storage.  The product made according to the invention can provide effective control of horn flies on cattle for six months or more utilizing a single ear tag or the like where it would take two tags constructed according to the prior art to achieve comparable results.   The result is lower costs in product and labor,  greater safety to an animal and workers and a lower quantity of residual product to dispose.
