Background and Identification
The Integra Camino is an intracranial pressure and temperature monitor made by Integra LifeSciences. Integra LifeSciences sells a range of medical devices for orthopedics, neurosurgery, and reconstructive and general surgery.
This monitor obtains intracranial pressure readings using a fluid-filled transducer connected to an external ventricular drain. The device must be leveled to the patient and turned off to cerebrospinal fluid drainage. The Integra Camino collects one accurate intracranial pressure each hour; during any other time, the pressure reading from the monitor may not be accurate unless the device stays level to the patient and is open to cerebrospinal fluid.
The Integra Camino monitor features a 7.0-inch LCD display with a resolution of 800 by 480 pixels. Integra LifeSciences advertises that the numeric parameters displayed on the device’s touchscreen can be read from up to 10 feet away. The device can be powered by a 14.4-inch lithium-ion battery or an AC power adapter.
The Integra Camino includes the name “CAMINO” printed in white capital letters at the top of the device’s front face. The device’s body is mostly light grey plastic and includes a handle at the top for transportability.
