Abstract: A volume metering dispenser comprises a body having a fluid cavity therein. The body further has a body wall, at least a portion of which is transparent or translucent, thereby permitting the operator to see the level of fluid within at least a portion of the fluid cavity. A valve is disposed within the body portion, the valve comprises a seal. The seal is selectively engaged to the body in order to selectively dispense fluid. The volume metering dispenser further comprises a resilient member. The resilient member is elastically deformable and the valve is attached to the resilient member.

Abstract: Devices, systems, and methods for measuring tissue oxygen saturation (StO2) within the body are disclosed. A patient interface for use with a tissue measurement instrument can include a spring clip having a first arm and a second arm, a spring configured to bias the first and second arms together, and a means for optically connecting the patient interface to the tissue measurement instrument. The patient interface can be used in conjunction with an optical sourcing and receiving unit of a monitor for measuring tissue oxygen saturation at a measurement site on the patient. A testing interface on an external portion of the instrument housing and a testing module can be used to perform tests on the instrument.

Abstract: Devices, systems, and methods for measuring tissue oxygen saturation are disclosed. An illustrative spectrometer for interfacing an optical sensor with a display unit includes a number of measurement radiation sources, a number of radiation source fibers each optically coupled to one of the measurement radiation sources, a reflected radiation fiber optically coupled to the optical sensor, a measurement radiation output fiber including an image fiber, and a radiation mixing bar intermediate the radiation source fibers and the measurement radiation output fiber.
