摘要： A small portable infusion device (10) for ambulatory use by a patient, includes an audible enunciator integrated circuit chip (96). This chip is controlled by a microprocessor to provide output data to an operator, and to work in place of, or in association with, a visual output display (91), such as an LCD screen. The audible data output permits a remote clinician to monitor operation of the pump, diagnose, and correct problems with the pump's operation.

摘要： A medical adapter having both a needleless valve and a sharpened cannula is used to connect or adapt pierceable septa containers or other devices having different sizes to needleless connection. The adapter includes a needleless site at one end and a sharpened cannula at the other end protected by spring arms. These arms include claws at their distal ends to grasp the neck of the pierceable septum device to which the sharpened cannula is to be inserted. The claws include sharpened points for gripping the device. The arms are located on either side of the adapter body and are connected to the body through springs. Handles are also included on the arms for use by the operator to separate the arms against the spring forces during engagement of the adapter with the septum. In one case, the handles include finger grips located above the springs for pressing the handles inward to open the arms and claws and in another case, the handles are located closer to the distal ends of the arms for pulling the arms outward. The adapter in one case comprises only three parts for reduced materials and manufacturing expense.

摘要： A syringe driver system comprises a rotatable threaded lead screw shaft and a plunger which directly engages the threaded shaft such that rotation of the shaft drives the plunger into the syringe body. The plunger is formed with a threaded shaft engaging portion in the form of a half nut to engage with and follow the threaded shaft. The syringe driver system further comprises a guide system to secure the plunger in direct engagement with the threaded shaft and to prevent rotation of the plunger. An arm of the plunger stem carries markers useful in determining the near end of infusion. The syringe body carries a marker or markers useful in determining a characteristic about the syringe, such as its volume.

摘要： A catheter integral with a valved needle-free connector provides a safety catheter device configured to receive a blunt cannula and sharp needle forming an insertion mechanism. The sharp needle is mounted within a needle tube and a control handle is used to slide the sharp needle out of and into the protective needle tube. When the insertion mechanism is mounted to the connector and the control handle is used to slide the sharp needle out of the tube, a blunt cannula first moves into contact with and enters the bore of the valve mechanism of the connector opening it and protecting it from damage that may be caused by the sharp needle. The sharp needle is then extended through the connector and extends out the distal end of the catheter so that a venipuncture procedure may be performed to properly locate the catheter in the patient's circulatory system. Once located, the needle may be retracted into the insertion mechanism, the insertion mechanism disconnected from the connector, and discarded.

摘要： A magnetic automatic stop valve formed in a container of a medical fluid administration system has one magnetic element located in a float and another magnetic element located proximate a valve seat. As the fluid level in the container decreases, the magnetic field established between the float and the valve seat eventually overcomes the buoyancy of the float in the fluid and attracts the float into the valve seat at which position the flow of fluid from the container is stopped. The float is formed of two identical halves each of which has one half of an internal post. When joined together to make the float, the internal post is fully formed and extends from one end of the float to the other. One magnetic element is slid over the post during manufacture and is free to slide from one end of the float to the other. Due to the symmetrical nature of the float and the freedom of movement of the internal magnetic element on the post, the float may be inserted into the fluid container without regard to which direction it faces thus lowering manufacturing costs. Flow seals are provided to completely shutoff flow when the float is seated.

摘要： A fluid infusion pump includes a platen between an outer door and the pumping mechanism. The platen is located so that as the outer door of the pump is moved to the closed position, it moves the platen to position the fluid flow tube into occlusive contact with the pumping mechanism before the platen engages a flow stop formed integrally with the tube and releases the flow stop to permit fluid flow, thus avoiding a free flow condition. The door also includes a handle having a sear with a hook that engages the flow stop when the door is in the closed position. As the door is opened, the hook moves the flow stop to the occluded position before the platen is moved away from the tube thus preventing a free flow condition. The platen includes a flow stop release portion that is offset from the remainder of the platen that operatively engages a release tab on the flow stop to permit movement of the flow stop to the fluid flow configuration. The platen is mounted to the housing with a floating hinge and datum pins located on the face of the pumping mechanism precisely locate the platen into position with the pumping mechanism and thereby result in precise positioning of the fluid tube.

摘要： In accordance with the present invention, a modular patient care system provides patient monitoring and the supply of therapeutic requirements. Specifically, the system is comprised of an interface unit and a plurality of patient functional units. The interface unit provides an interface between the user and the system, and may be configured and adapted to provide different levels of functionality. Interface units with different levels of functionality may be interchanged so as to provide greater flexibility, safety, and cost effectiveness. Each interface unit contains interface ports for the transfer of information such as drug libraries, system configuration values, and event history. The functional units are internally programmed and controlled so as to provide a high level of system modularity, and require only power and interfacing functionality from the interface unit.

摘要： A system for controlling fluid flow through multiple conduits for use in a fluid administration device. The system includes a housing, a cam, and a control element used to move the cam to selectively occlude the conduits. When used with a medical burette, the cam is located between the vent and supply conduits and rotates to alternately occlude one or the other conduits or to leave both conduits patent. A cam lobe occludes the conduits by pressing the conduit against a pressure surface until occlusion is obtained. Depending on the rotational position of the cam, the continuous flow mode, the intermittent flow mode, and the priming mode are all obtained with a single control lever. The housing secures the conduits in predetermined, fixed positions both above and below the contact location of the cam to the conduit. A positive locking device is included to assist in locating the cam in the desired position. A tactile sensation is also provided to the operator by the locking device to indicate that the cam has been placed in the desired location. Clear visual indicators are included on the housing so that the flow mode in which the burette is presently operating can be seen from a distance.
