    摘要: A compact, integrated intravenous fluid delivery device. In one embodiment, the invention may be used with first and second intravenous fluid sources and an intravenous fluid line. This embodiment includes a spike for connecting the device to the first intravenous fluid source. A fluid passageway passes through the spike. A connection site (e.g. a puncture site) connects the device to the second intravenous fluid source. This embodiment also includes a drip chamber, through which the fluid may flow to the intravenous fluid line. This embodiment may include an adjustable valve, which includes a flexible tube mounted so that fluid may pass from the fluid passageway in the spike, from the connection site, and through the tube. The valve includes an actuator mounted with respect to the tube so that it may be urged to compress the tube. The spike, the adjustable valve, and the drip chamber are rigidly attached to each other, with no flexible tubing between the various components. This embodiment may further include a one-way valve mounted below the spike and above the connection site, so that intravenous fluid may flow from the fluid passageway through the one-way valve, and so that fluid from the second fluid source may flow to the intravenous fluid line, but may not flow through the fluid passageway in the spike.

    摘要: In a fluid flow control system a weight comparator compares the weight of fluid in a reservoir with a weight reference that is programmed to decrease at a desired rate. A fluid flow comparator compares the actual fluid flow rate with a programmed fluid flow rate and operates directly on a flow controller to control fluid flow in the system. The weight comparator operates indirectly on the flow controller by recurringly updating the programmed fluid flow rate so that flow is controlled on a current basis by the fluid flow comparator and on a long-term basis by the weight comparator.

    摘要: An infusion pump has a removable reservoir including a piston and drive member. The drive member is an internally threaded elongated portion of the piston. A motor rotates a short drive screw, which engages the threads of the drive member to displace the piston in the reservoir. In one embodiment the piston is attached to the drive member by a severable central stem which breaks away to allow engagement with the drive screw. With the stem severed, the piston cannot be retracted, or the reservoir refilled. Other safety features are shown for locking the displaced piston in the reservoir. A digital metering system has a safety circuit to prevent dangerous failure modes of the rotation sensor and motor drive systems.

    摘要: A unitary sheet device for removably securing a catheter to the skin of a patient includes a pair of flaps for being affixed to the skin and a central portion performed in a contour conforming to the catheter hub. When affixed, the central portion and the patient's skin together form a receptacle for securely holding the catheter against movement. The central portion may be a tapered conical sheet and the flaps may have adhesive for ease of attachment. A detent is provided, which may include a hole through the central portion of the sheet for engaging a protrusion from the catheter hub. Flexing of the sheet disengages the detent. A non-adhesive tab on one flap aids in removing the device.

    摘要: In a system for controlling flow of fluid from a reservoir to be delivered intravenously to a patient, a valve adjustably constricts a fluid path and maintains a given adjustment until the adjustment is changed. In a preferred embodiment, a valve assembly is insertable into a servo assembly that controls flow through the valve. The valve can be removed from the servo assembly and, when so removed, will retain its last adjustment. A preferred embodiment of the valve utilizes a screw to compress a tube of resilient material.

    摘要: A device for transporting a human subject over a surface. The device is a dynamically balancing vehicle having a control loop for providing balance. The device includes a platform defining a fore-aft plane. The platform supports a payload including the human subject. A ground contacting module is included which may include one or more wheels. A ground-contacting member is movably coupled to the platform. The platform and the ground-contacting module form an assembly having a center of gravity that is defined with respect to the ground-contacting member and which includes any loads on the device. The device further includes a support. The support may be a seat for supporting the subject and the support is coupled to the platform in such a manner as to permit variation of the position of the center of gravity in the fore-aft plane by translation and rotation of at least a portion of the support. In one embodiment, translation and rotation of the seat of the device are mechanically coupled together.
