A microvolume 3-way stopcock for use in a blood sampling system. The stopcock includes a stopcock body having a cylindrical-shaped central chamber, an inlet fluid passage extending from the central chamber to a connector, a blood sample fluid passage extending from the central chamber to a connector, and a waste fluid passage extending from the central chamber to a connector. A rotatable flow control member having a T-shaped fluid passage is disposed within the central chamber. The rotatable flow control member provides adjustable fluid communication between the inlet, blood sample, and/or waste fluid passages. The stopcock is configured with a small dead space volume in the range from about 0.02 mL to 0.20 mL. A cannula may be connected to the inlet fluid passage. The combined dead space fluid volume of the stopcock and cannula may range from about 0.03 ml to 0.24 mL.

Microvolume 3-way stopcock and method for obtaining clean blood specimen

The present invention relates to a disposable medical-examination light. Specifically, the invention relates to a disposable light for use with a speculum. Generally, the disposable light includes a casing with an interior and an exterior. The casing interior may be adapted to hold at least one battery. The casing exterior may include a proximal surface and a distal surface. A protrusion may extend from the proximal surface, and at least one light-emitting diode ('LED'), such as a white and/or green light producing LED, may be substantially disposed at a proximal end of the protrusion. Additionally, a gripping mechanism may extend from the casing's proximal surface. The disposable light may also comprise electrical components for connecting at least one battery to at least one LED. Furthermore, the disposable light may also include a switching mechanism that may be configured to close an electrical circuit between an LED and a battery.
