Abstract: A variable device for regulating the outlet pressure of a fluid from a valve body, includes a pressure-sensing chamber having a wall formed by a resilient self-restoring diaphragm which is responsive to pressure in the chamber. A valve element connected to the diaphragm controls flow into the chamber. Increased pressure in the chamber decreases the flow into the chamber and decreasing pressure increases flow whereby fluid flow out from the chamber is maintained at a desired pressure. The outlet pressure is adjusted by deflecting the diaphragm in a direction to open the valve while permitting a section of the diaphragm connected to the valve member to remain responsive to the pressure in the chamber. An adjustment cover is provided to adjustably deflect the diaphragm and includes a catch mechanism to allow adjustment of the fluid outlet pressures and also retain the device at a desired value. An indicator arrangement may be provided to visually indicate the fluid outlet pressure.

Abstract: Disclosed is an infusion pump for expelling a fluid from a collapsible fluid reservoir to a patient. The pump includes a housing having a chamber therein for receiving the fluid reservoir. A first wall is provided on the housing for contacting the fluid reservoir, and a second wall is movable from a first position distanced from the first wall to form the chamber therebetween, and a second position relatively closer to the first wall. Advancing the movable wall from the first position to the second position expels fluid from the collapsible reservoir at a substantially constant rate by applying increasing force on the fluid reservoir through the dispensation cycle. Preferably, the first and second walls are provided with non-planar complementary surface configurations for contacting the collapsible reservoir. Retraction mechanisms for retracting the movable wall from the second position to the first position, and user readable indicium of the status of the dispensation cycle are also disclosed.

Abstract: A PCA device includes a fluid conduit having an upstream portion and a downstream portion, a first flow-restricting orifice in the upstream portion, a second flow-restricting orifice in the downstream portion, a pressure-responsive check valve in the downstream portion in parallel with the second flow-restricting orifice, and a bolus dose delivery mechanism including a chamber in fluid communication between the upstream portion and the downstream portion. Continuous flow is provided through the first flow-restricting orifice, the chamber, and the second flow-restrictive orifice, the continuous flow serving to fill the chamber at a controlled rate through the first flow-restrictive orifice. The bolus dose delivery mechanism is manually actuable to express the contents of the chamber through the check valve to supplement the continuous flow through the downstream portion. The bolus dose delivery mechanism includes a resilient diaphragm that forms a sealed closure for the chamber. The diaphragm is movable from a decompressed position to a compressed position by a plunger that directly engages the diaphragm, and it is restored to the decompressed position by the flow of fluid into the chamber.

Abstract: An infusion pump for providing a pressurized liquid flow from a collapsible, deformable reservoir bag includes a magnetically actuated pressurizing member that applies a pressure to the bag in response to the force of magnetic attraction applied by a magnet. In several embodiments, a bag is seated on a platen of magnetizable metal, and a magnet with a compressing surface is mounted for movement toward and away from the platen. As the magnet is moved toward the platen by the force of magnetic attraction, the bag is pressurized between the magnet and the platen. The magnet may be spring biased either toward or away from the platen to alter the relationship between the decreasing volume of the bag and the pressure applied to it, by compensating in a known manner for the change in the magnitude of the magnetic force with the distance between the magnet and the platen. In another embodiment, a pair of magnets are pivotably attached to opposed edges of the platen, so as to be pivotable, "drawbridge" style, toward and away from the platen. In still another embodiment, a fixed magnet attracts a magnetizable metal plate which is connected, by a pivoting linkage, to a pressure plate. A reservoir bag is placed between the pressure plate and a fixed surface. As the metal plate moves toward the magnet, the linkage causes the pressure plate to move toward the fixed surface, pressurizing the bag therebetween.

Abstract: An injection set with a slit septum held in place in the inlet of a housing by a cap affixed to the inlet. A concave end of the septum is exposed through an aperture in the cap, and a peripheral flange portion of the septum is squeezed between the housing inlet and the cap, causing the septum's concave end to bulge and flatten, thus improving the sealing of the septum's slit. Extending through the septum slit is a drug transfer spike having a ball-shaped tip sharp enough to penetrate the diaphragm of a drug vial but not so sharp as to puncture the skin of a user.
