HotDog WC77 Controller - Advanced Patient Warming

Advanced Patient Warming System

The HOTDOG WC77 is the most advanced patient warming system ever developed. It is designed to provide maximum versatility and efficiency in patient temperature management, bringing the HotDog Patient Warming System to the forefront of advanced, patient-centered care. The aesthetics, touch screen interface, communication features, data feedback, and overall functionality are all designed to benefit the clinician and patient. It is compatible with older and current warming blankets, mattresses, and cables.

7-inch touch screen with Intuitive User Interface

The WC77 features a 7-inch touchscreen with an intuitive user interface. This reliable patient warming system is at your fingertips, allowing you to control all devices at once or individually by touch. Patient warming has been simplified so you can focus on other aspects of the procedure.

Temperature Monitoring

The WC77 offers temperature monitoring, displaying patient core temperature on the screen or an external monitor. This feature allows you to keep track of your patient’s temperature from the start to the end of the procedure. Core temperature is always readily available on the interface.

Customizable Graph Display

The WC77 features a customizable graph display, allowing you to zoom and scroll to any time of the procedure to view temperatures at every moment, from beginning to end.

Auto Mode

The temperature monitoring feature allows automatic control and adjustment of the warming devices based on the patient’s temperature.

Powers multiple devices at once

The WC77 can power multiple devices at once. It can use up to 4 warming blankets with ports A (located on the front) through D at one time. Additionally, a warming mattress can be added with Port M to warm above and below simultaneously. All devices can be controlled at once or individually to suit your needs.
