Innovative Veterinary Anesthesia Systems
DarvallVet, the North American division of Advanced Anesthesia Specialists, has been at the forefront of veterinary anesthesia innovation since our founding. Established by Dr. Colin Dunlop, a former Head of Veterinary Anesthesia at Colorado State University, our team combines decades of clinical expertise with advanced engineering to address longstanding challenges in veterinary critical care. We specialize in developing precision anesthesia equipment, including heated breathing circuits, zero dead space masks, and energy-efficient gas machines tailored for small animals, exotics, and research environments. Our commitment to education and technical support ensures practitioners receive comprehensive training and resources.

Recognized globally for introducing the first temperature-controlled breathing circuit, we maintain rigorous quality standards through ISO-compliant manufacturing processes. By prioritizing animal safety and practitioner efficiency, weve pioneered solutions that reduce anesthetic waste gas exposure by 90% and hypothermia risks during procedures. Our patented Cozy warm air blanket system and right-handed laryngoscopes demonstrate our dedication to practical, user-focused design. With technical services available worldwide and products distributed across veterinary hospitals and research facilities, we remain dedicated to advancing anesthesia protocols through continuous research and collaboration with industry professionals.

Services
Heated Breathing Circuits
Our patented heated breathing circuits actively warm anesthetic gases to prevent hypothermia in veterinary patients. The system maintains gas temperatures between 98F-103F through computer-controlled heating, with safety sensors that automatically adjust based on patient temperature readings. This technology helps reduce recovery times and complications associated with cold anesthetic gases, particularly in small animals and prolonged procedures.
Zero Dead Space Masks
The Zero Dead Space (ZDS) mask system eliminates residual gas buildup during anesthesia delivery. These unidirectional flow masks provide precise anesthetic control while reducing gas consumption by 80-90%. The sealed design prevents workplace contamination and improves efficiency, with specialized models available for rodents, exotics, and stereotaxic surgical applications.
Warm Air Blanket Systems
The Cozy Warm Air Blanket System delivers consistent patient warming through specially designed porous blankets and high-efficiency heaters. The system includes cage adapters that allow temperature maintenance during recovery without disturbing patients, with clinical data demonstrating effectiveness in maintaining normal body temperature throughout surgical procedures.
Anesthetic Gas Machines
Our Stinger series gas machines offer durable, low-flow anesthesia delivery systems with modular configurations. Features include dual flowmeter options, high-efficiency CO2 absorption systems, and portability enhancements like waterproof Pelican cases for field applications. Models are available for small animals, research settings, and mobile veterinary services requiring ruggedized equipment.
Waste Gas Management
Our sealed circuit systems and dedicated scavenging solutions prevent waste anesthetic gas accumulation in clinical environments. The integrated designs reduce exposure risks by 80-90% while maintaining anesthesia precision through our proprietary circuit technologies and active ventilation systems compatible with standard veterinary equipment.
