Breathing Bags


A breathing bag is an accessory used in the respiratory anesthesia system for gas storage, helping to regulate gas flow.When the gas supply exceeds system demand, the excess is temporarily stored in the bag; when the supply falls short of system demand,the bag deflates, releasing its stored volume to supplement the supply, acting as a gas flow buffer. Undis breathing bags are available in latex, latex-free, silicone, and PE materials.

Complete specifications, multiple configurations available

In addition to conventional breathing bag sizes (0.5L, 1L, 2L, 3L), Undis offers a 5L model to accommodate patients of different body sizes both domestically and internationally. An optional ring is available at the tail end of the breathing bag. If a smaller volume breathing bag is temporarily needed but not in stock, the bag can be folded in half and hung on the top clip.

 

Integrated process for a tight connection

Securely connected to the bag, 22mm standard connector ensures a tight fit with anesthesia machines or breathing circuits, effectively maintaining the preset anesthetic gas concentration. The connector allows for smooth insertion and removal.This effectively prevents accidental dislodgement during surgery and enhances surgical safety.
