Locking Ventilation Bag

The Locking Ventilation Bag ensures that a ventilation bag is securely attached to a gas machine during anesthesia.


The removable ventilation bag on anesthetic gas machines is widely used during surgical procedures requiring anesthesia. During routine ventilation and anesthetic emergencies, the bag often “pops” off the arm of the ventilator due to the pull of the anesthesia provider’s hand during manual ventilation and changes of pressures. This temporary malfunction is a design flaw that disrupts ventilation, oxygen delivery, and anesthetic gas delivery which poses a health risk to patients during anesthesia. A ventilation bag with a secure connection to the gas machine is paramount to provide a continuous, uninterrupted delivery of anesthetic gases and oxygen during anesthesia.


The Locking Ventilation Bag is a ventilation bag with a built-in, secure locking mechanism. The bag lock device attaches the disposable ventilation bag to the top of the gas machine arm by secure side straps. The novel design augments the disposable ventilator circuit by ensuring continuous and uninterrupted manual ventilation of a patient during anesthesia and enables rapid removal when necessary. This product ensures that positive pressures and anesthetic levels can be maintained without interruption during both routine ventilation and emergency situations.

Competitive Benefits

  • Safe, reliable, continuous ventilation
  • Bag lock device ensures the continuous delivery of oxygen and anesthetic gases
  • Bag lock device can maintain uninterrupted delivery of positive pressure, even during anesthetic emergencies
  • Design of side strap allows for easy removal in case of malfunction, transport, cleaning or emergency
  • Widespread use for general anesthetic procedures
  • Large potential market of gas machine and ventilator circuit suppliers considering one circuit use per anesthetic/patient

Application Fields

The Locking Ventilation Bag can be used for general anesthetic procedures, such as mask ventilation, laryngeal mask anesthesia, maintenance and sedation cases, induction, emergency and transport after general anesthetic to post-anesthesia care unit.

Stage of Development

A prototype has been designed.
