    摘要： A non-invasive technique and system is provided for measuring flow of liquid driven by a flexible diaphragm of a membrane pump (18). Flow, pressure and/or temperature of a gas, such as air, used to drive the pump (18) is continuously monitored. Instantaneous volume of liquid being pulled into or out of a chamber of the pump (18) can be calculated from measured values of the gas used to drive the pump (18). Sensors (10, 12 and/or 14) are used to measure values relating to the gas. The sensed parameters are concurrently monitored and continuously determine the amount of gas flowing to and from the diaphragm of the membrane pump (18) utilized to move liquid within a liquid pathway. The measurements may then be used to calculate the instantaneous flow rate of the liquid.

    摘要： An electrode for use in cooperation with a signal-receiving apparatus is the subject matter of this invention. The electrode receives an electrical signal from a subject, which signal is then observed. The electrode includes an electrical half cell. The half cell includes a metal and an electrolyte solution. A diaphragm holds the electrolyte in contact with the metal. The diaphragm is sufficiently permeable to allow ionic conduction between the surface of a subject and the electrolyte.

    摘要： Sample tube racks having retention bars to retain sample tubes in the racks during processing of the contents of the sample tubes are described. An example rack for holding sample tubes includes a sample tube carrier having an elongated body and walls defining apertures. Each of the apertures is configured to receive a respective one of the sample tubes. The walls define elongated openings, each of which corresponds to a respective one of the sample tubes and extends along at least a portion of a length of the respective sample tube, and the elongated openings enable viewing of information on the outer surfaces of the sample tubes. The example rack also includes an elongated retention bar to be pivotally coupled to one end of the sample tube carrier. The retention bar has openings, each of which is positioned over a respective one of the apertures, and the openings are dimensioned to prevent removal of the sample tubes from the sample tube carrier through the retention bar.
