Non-Rebreathing ZDS Masks and ZDS Qubes, and Accessories
Darvall Zero Dead Space (ZDS) Masks and Zero Dead Space (ZDS) Qubes feature uni-directional gas flow which eliminates dead space and allows low fresh gas flow.
Darvall ZDS* Masks
Darvall ZDS Masks provide predictable delivery of anesthesia for birds, reptiles and exotics. The stream-lined flow eliminates dead space, avoiding the need for tight fitting face masks.
Features & Benefits:
- Delivers inlet gas directly into patient mask (zero dead space) for more rapid and predictable anesthesia
- Reliable control of anesthetic delivered to patient
- Diaphragm openings available to suit a range of animals, from rats and mice to small animals and exotics.
- More efficient single animal induction of small animals and exotics
- Two diaphragm sizes included
- Available as autoclavable or economical non-autoclavable.
Darvall ZDS Qubes*
Darvall ZDS Qubes bring new solutions to the longstanding anesthesia problems encountered by zoo veterinarians, academics, and pocket-pet practitioners.
- Eliminate waste gas pollution
- Increase efficiency
- Reduce morbidity / mortality
- Maintain predictable anesthesia
Features & Benefits:
- Lo-flo Zero Dead Space (ZDS) design – enhances response to changes in anesthesia, allows for fast & predictable anesthesia, and efficient gas flow
- Sealed mask system – saves money with up to 80% decrease in anesthetic and oxygen consumption and reduced waste gas volume
- Solid, heavy cube design – secure and stable for improved patient positioning
- Complete range of models, masks and diaphragms available – accommodates puppies and kittens, to a most pocket pets

ZDS Qubes and ZDS Masks offer solutions to these longstanding problems
Waste gas contamination of workplace.
- “Sealed” mask prevents leakage into workplace
- High-flow waste gas scavenging NOT required to prevent anesthetic agent contamination
- Capacity of active gas scavenging system reduced ~80%
Inadequate anesthetic depth.
- Zero dead space (ZDS*) mask, uni-directional flow design delivers gas direct to patient, preventing rebreathing
- No unpredictable “leakage” of delivered gas
Long, uncontrolled inductions.
- Use ZDS Qube* for induction
- Yields rapid, controlled induction
- Eliminates patient transfer from chamber to procedure site, minimizing workplace contamination
Time (and tape) in patient set-up.
- Unique anesthesia solution (patent pending)
- Solid aluminum (1 lb) design gives positioning stability
- Hoses secured and fixed in place automatically
- Eccentric mask aperture gives multiple patient heights
- Wide range of masks & diaphragms to suit most animals and procedures
Morbidity/mortality due to hypothermia.
- Reduces fresh gas flow by 80 – 90% (inflow oxygen is cold and dry)
- Eliminates high scavenge system air flow around patient to resolve hypothermia
- Heated ZDS Qube* provides warmed inspired gas
High anesthetic costs.
- “Sealed” mask system reduces anesthetic/oxygen consumption
- Gas flow (and consumption) reduced 80 – 90%
- Typical 1 – 2 liters/min flow reduced to 100 – 200 mls/min
* = patents pending
HEATED Darvall ZDS Qubes
Darvall HEATED ZDS Qube warms patients from within. Our totally new warming technology features a heat controller with a microprocessor and temperature sensors. Together they warm the patient’s inspired air to between 98ºF and 103ºF.
- Prevents hypothermia in rodents and other pocket pets
- Warms from the start of anesthesia
- Controlled heating: 98ºF – 103ºF
- Continuously monitors patient’s temperature
- Safe: closed-loop feedback
- Eliminates waste gas pollution
- Increases efficiency
- Reduces morbidity / mortality
- Maintains predictable anesthesia
Features & Benefits:
- Warms From Within!
- Captures control of patient’s body temperature from induction
- Increase your precision by adding an optional esophageal / rectal temperature probe
- Lo-flo Zero Dead Space (ZDS) design – enhances response to changes in anesthesia, fast & predictable anesthesia, and efficient gas flow
- Sealed mask system – save money with up to 80% decrease in anesthetic and oxygen consumption and reduced waste gas volume
- Solid, heavy cube design – secure and stable for improved patient positioning
- Operates as Heated or Non-Heated
- Complete range of masks and diaphragms available – accommodates rodents, kittens, and most pocket pets
