摘要： An infusion system includes a characteristic determining device and an infusion device. The characteristic determining device includes a receptacle for receiving and testing an analyte from the user to determine a concentration of the analyte in the user. The characteristic determining device also includes a communication system for transmitting a communication including data indicative of the determined concentration of the analyte in the user, and the infusion device includes a communication system for receiving the communication from the characteristic determining device. The infusion device further includes a bolus estimator for calculating an estimated amount of fluid to be infused into the body of the user based upon the received data indicative of the determined concentration of the analyte in the user and a target concentration of the analyte in the user, and an indicator to indicate when the estimated amount of fluid to be infused has been calculated.

摘要： A selectively protected electrical system includes or operates with a power source, a load, a power driver circuit for controllably transferring power from the power source to the load, the power driver circuit being encapsulated in a potting material, and a controller for enabling and disabling the power driver circuit, the controller being un-encapsulated by the potting material. If a contaminant induced electrical fault occurs in the selectively protected electrical system, the electrical fault is more likely to occur in the un-encapsulated controller, such that the selectively protected electrical system is disabled. The contaminant is inhibited from contacting and inducing an electrical fault in the power driver circuit, thus providing for a controlled failure of the selectively protected electrical system.

摘要： An improved pump, reservoir and reservoir piston are provided for controlled delivery of fluids. A motor is operably coupled to a drive member, such as a drive screw, which is adapted to advance a plunger slide in response to operation of the motor. The plunger slide is removably coupled to the piston. A method, system, and an article of manufacture for automatically detecting an occlusion in a medication infusion pump is provided. The electrical current to an infusion pump is measured. Based on measurements of one or more variables, the infusion pump detects whether there is an occlusion in the system. The methods of detecting occlusions may be dynamic.

摘要： An improved reservoir is provided for use in a medication infusion device for operating the reservoir to administer a fluid to a patient. The reservoir comprises a hollow barrel adapted to receive a supply of fluid for delivery through infusion tubing or the like to the patient, in combination with a reservoir plunger. The reservoir plunger is designed to engage a motor-driven lead screw of the medication infusion device. The reservoir plunger has an integral split nut connector formed on the end of the plunger, which is in co-axial alignment with the lead screw whereby the split nut connector can be engaged directly to the lead screw.

摘要： Methods and apparatuses for calculating and transmitting medication dosage or bolus information are provided. A blood glucose meter receives a test strip with a sample of the user's blood and measures the user's blood glucose level with a sensor. The meter then calculates a bolus amount that is transmitted to a medication infusion pump using a radio frequency transmitter or transceiver. The infusion pump receives the bolus amount data and then delivers a bolus of medication to the user based on the calculated bolus estimate. The meter may also transmit commands to, and be used to remotely control, the infusion pump.

摘要： In a fluid delivery system for delivering a fluid into an individual's body, a leak detection system indicates that the fluid has leaked outside a normal fluid path of the fluid delivery system, such as near an infusion site or a fluid-filled reservoir. Preferably, the leak detection system includes a chemical positioned near the infusion site that reacts with preservatives in the leaking fluid to generate a highly visible, brightly colored, chemical complex. Alternatively, mechanical, electro-optical, electrochemical, electrical or other chemical systems may be used to detect the presence of fluid that is leaking near the infusion site. Further, the leak detection systems may be used to detect the presence of fluid that is leaking from or near other locations within the fluid delivery system, such as on or near a fluid-filled reservoir, or a flexible tube coupled between the reservoir and the infusion site.

摘要： A closed loop infusion system controls the rate that fluid is infused into the body of a user. The closed loop infusion system includes a sensor system, a controller, and a delivery system. The sensor system includes a sensor for monitoring a condition of the user. The sensor produces a sensor signal, which is representative of the condition of the user. The sensor signal is used to generate a controller input. The controller uses the controller input to generate commands to operate the delivery system. The delivery system infuses a liquid into the user at a rate dictated by the commands from the controller. Preferably, the sensor system monitors the glucose concentration in the body of the user, and the liquid infused by the delivery system into the body of the user includes insulin. The sensor system uses the sensor signal to generate a message that is sent to the delivery system. The message includes the information used to generate the controller input. The sensor may be a subcutaneous sensor in contact with interstitial fluid. Also, two or more sensors may be used by the sensor system.
