    摘要： An apparatus is provided for monitoring a predetermined parameter of a patient's body fluid while infusing an infusion fluid into the patient. The apparatus comprises an infusion line and a catheter configured for insertion into a blood vessel of the patient, and a reversible infusion pump connected between a source of an infusion fluid and the infusion line and catheter. The apparatus further comprises a body fluid sensor assembly mounted in fluid communication with the infusion line and which includes a first sensor and a sample cell. The first sensor provides a signal indicative of a predetermined parameter of any fluid present in the infusion line. The sample cell is substantially transmissive to light comprising a wavelength λ. The apparatus further comprises a controller that is configured to operate the infusion pump in a forward direction so as to pump the infusion fluid through the infusion line and catheter for infusion into the patient. The controller is configured to intermittently interrupt its operating of the infusion pump in the forward direction to operate the infusion pump in a rearward direction so as to draw a body fluid sample from the patient through the catheter and infusion line. The body fluid sample drawn from the patient is disposed such that a first portion of the body fluid sample is in sensing contact with the first sensor of the body fluid sensor assembly, and a second portion of the body fluid sample is disposed within the sample cell of the body fluid sensor assembly. The controller further is configured to monitor the signal provided by the first sensor of the body fluid sensor assembly and to detect a change in the signal indicative of the arrival of the body fluid sample at the first sensor. The controller, in response to detecting the arrival of the body fluid sample at the first sensor, is configured to cease its operating of the infusion pump in the rearward direction. The signal produced by the first sensor provides an indication of a predetermined parameter of the patient's body fluid when the body fluid sample is in sensing contact with the first sensor.

    摘要： Disclosed are systems, apparatus and methods for determining information related to analyte(s) (e.g., concentration) in a sample such as biological fluid. An analysis system for determining information relating to at least one analyte in a sample of biological fluid can be configured to: withdraw the sample of biological fluid from the source of biological fluid; interrupt the flow of infusion fluid while the sample of biological fluid is withdrawn; analyze the withdrawn biological fluid to determine information relating to at least one analyte; and resume the flow of infusion fluid after the sample of biological fluid is withdrawn. A method of interrupting flow of an infusion fluid without triggering an alarm can comprise, while the flow of the infusion fluid is interrupted, diverting the flow of the infusion fluid from a fluid passageway to an expandable volume at a rate that maintains constant flow from an infusion pump.

    摘要： A coupling pad can be used with a transducer element. Ultrasound produced by the transducer element can be propagated through the coupling pad to a patient. In one arrangement, the pad is a pouch containing a pliant substance. In other arrangements, the pad is a somewhat solid member formed of a material that transmits ultrasound waves efficiently. The pad may be configured to fit between a patient's skin and a transducer element so that output from the transducer element passes through the pad to a treatment site of the patient.

    摘要： The invention is concerned with digital communication systems and there is disclosed a digital telephone system wherein any digital telephone may be switched, by control from a local exchange, between a power-up state wherein continuous operating power is consumed by the telephone and a power-down state wherein the telephone is effectively turned off except for the consumption of a small amount of power sufficient only to enable communication between the telephone and the exchange. A telephone is powered-up by detecting, at the telephone, a control signal in the digital data transmitted from the exchange to the telephone. Each telephone includes a detection circuit for detecting the control signal and actuating a power rationing switch to switch the telephone to the power-up state. The power rationing switch may also be actuated momentarily when the telephone goes from the idle to busy condition to initiate a call so as to signal the exchange of the requirement for full operating power. The exchange is capable of deciding whether a telephone wishing to power-up can do so without causing exceeding of an allowable sum of power ration for the telephones of the system. A test center for digitally testing the lines between the exchange and the telephones is also disclosed. The test center causes a digital test signal to be transmitted from the exchange to a telephone at the end of a line under test wherein it is modified in a particular way and transmitted back to the exchange. The returned test signal is compared, at the test center, with a similarly modified non-transmitted test signal enabling a count of the errors to be made. The S/N ratio on the line under test is reduced to increase the errors.
