Looking for a Parks Doppler? Parks Medical Doppler flow detectors are the standard handheld vascular Doppler in hospitals, clinics and vascular labs, and the Parks 811-B is also widely used as a veterinary Doppler for indirect blood pressure in dogs and cats.

IPR Medical offers Parks Medical ultrasonic Doppler flow detectors, including the 811-B, the 811-BL with cautery suppressor, the 811-BTS with auto-shutoff and the dual-frequency 915-BL. We buy and sell new and recertified Parks units, stock genuine Parks replacement components, and repair Parks Dopplers in-house as an authorized Parks Medical repair facility.

Parks Medical Electronics of Aloha, Oregon, was founded as Parks Electronics Laboratory in 1961, and Parks says its 811 series has been the most popular Doppler for more than 50 years. In 2025, JLL Partners acquired Parks and combined it with Vascular Technology, Inc. IPR Medical sells Parks Dopplers and repairs the Doppler units in-house; probes are sold as replacements, not repaired. See our Parks Doppler history and repair page.
