摘要： A formulation dispenser is disclosed for use in a parenteral delivery system. The dispenser comprises an inlet for admitting fluid into the dispenser and an outlet for letting fluid leave the dispenser. A beneficial agent is housed in a formulation chamber in the dispenser and a membrane permeable to fluid and agent defines one boundary of the formulation chamber. A piston is slideably disposed in the dispenser for governing the flow of fluid through the dispenser, or for permitting fluid to contact the membrane and enter the formulation chamber for forming a solution containing agent that flows through the outlet into the parenteral system.

摘要： A portable heart monitoring apparatus incorporating unique structural and functional features. Electrodes carried on the apparatus capture electrical signals representing the functioning of a heart beating therewithin and provides sensible output indications corresponding to predetermined characteristics of the electrical signals and, hence, of the detected heartbeat. One of the sensible outputs provided is the selective actuation of either of two logic lights indicating whether the heartbeat is above or below respectively a predetermined beating rate. The unit is automatically turned on by merely holding the instrument in the user's hand and the selective actuation of the various operational modes may be conveniently made by selectively placing one of the hands's digits (such as the thumb) from one touch contact point to another. Part of the operation in the test mode involves the effective testing of the reserve battery power without actually loading the battery. Structurally, the device is convenient to hold in the hand and includes, on one side, a ground plane for establishing electrical contact with the user's hand. The ground plane structure is also formed as an open-sided storage compartment for the electrodes and is surrounded by a wrap-around structure for self-storing of the electrode leads.
