LED Penlight is a helpful tool for assessing a patient's pupil response. Suitable for paramedics, nurses and other medical professionals, it features a sealed concentric beam. This penlight is also useful for examining the ears and throat for signs of inflammation or other symptoms. A pupil gauge on the side makes it easier to make a quick assessment of a patient's status. This medical penlight gives off a bright, white light for a rapid response and is reusable. The clip on the side serves to both hold it in a pocket and activate the light beam.
