ABSTRACT:
A two piece neurodiagnostic test instrument sensitive to the prevalence of blood borne pathogens in a clinical environment. The test instrument provides a weighted balance to conduct a proper neurodiagnostic test without fear of puncturing a patient's skin. The instrument alone and without additional force applied by the physician provides the necessary weight to achieve accuracy and consistency during an examination procedure. The test instrument includes a weighted stainless steel reusable handle with a disposable plastic pinwheel test head releasably attached thereto. The test head includes a first end with coupling arms which are inserted into a receptacle in a first end of the weighted handle. A second end of the test head includes a rotatable pin wheel with a shroud disposed around an upper portion of the pin wheel. The weighted handle includes a hollow elliptical tube with a spring biased ejector bar received inside the tube. One end of the ejector bar, which is used as an ejector button, extends outwardly from a second end of the tube. Upon the completion of a clinical test, the ejector button is pushed and the ejector bar urges the test head outwardly from the first end of the handle. The test head is discharged and received inside a waste container for disposal thereby allowing a physician to never contact the test head after its use.
