Abstract: A Doppler blood flow monitoring device includes a signal generation module, a signal reception module, a signal filtration module, a signal conversion module, at least one speaker, and a user interface. The signal generation module is configured to send a signal to a probe positioned in a probe receptacle on a vascular coupler positioned about a patient's vessel. The signal reception module is configured to receive a return signal from the probe. The signal filtration module is configured to filter the return signal. The signal conversion module is configured to convert the filtered signal into an audible indication and a visual indication corresponding to a characteristic of blood flow in the patient's vessel. The at least one speaker is configured to emit the first audible indication. Additionally, the user interface is configured to display the visual indication.

Abstract: A biological indicator reader is provided for reading a plurality of biological indicators to determine the effectiveness of at least a sterilization process. Each biological indicator is configured to exhibit fluorescence when the sterilization process has failed. Each reader comprises a housing having a plurality of biological indicator holders, a heater coupled to the housing and configured to heat the plurality of biological indicator holders to a preselected temperature to incubate the biological indicators, a UV light emitter configured to emit UV light through a first aperture on the side of each holder and an optical detector positioned under a second aperture on the bottom of the biological indicator holder, the optical detector configured to detect fluorescence intensity indicating the effectiveness of the sterilization process. A method of using the biological indicator reader is provided. A biological indicator system and display are also provided.

Abstract: A Doppler blood flow monitoring device (150) includes a signal generation module, a signal reception module, a signal filtration module, a signal conversion module, at least one speaker, and a user interface (304). The signal generation module is configured to send a signal to a probe (106) positioned in a probe receptacle on a vascular coupler positioned about a patients vessel. The signal reception module is configured to receive a return signal from the probe. The signal filtration module is configured to filter the return signal. The signal conversion module is configured to convert the filtered signal into an audible indication and a visual indication corresponding to a characteristic of blood flow in the patients vessel. The at least one speaker (214) is configured to emit the first audible indication. Additionally, the user interface is configured to display the visual indication.
