Flow Meter with Humidifier Bottle

A flow meter with a humidifier bottle is a medical device used to regulate and deliver oxygen from cylinders to patients while adding moisture to prevent airway dryness.

A flow meter with a humidifier bottle is designed for precise oxygen delivery in hospitals, nursing homes. It connects to standard medical oxygen cylinders and allows controlled oxygen flow to patients, ensuring comfort and safety during therapy.

Key Components

Flow Meter: Measures and controls oxygen flow, typically ranging from 0.5 to 10 L/min for adults, with some models supporting up to 15 L/min. The flow is adjusted using a control knob.

Pressure Gauge: Indicates cylinder pressure, often ranging from 0–250 kg/cm², helping monitor oxygen availability.

Humidifier Bottle: A transparent, autoclavable bottle filled with water to a marked level. It humidifies oxygen to prevent dryness in the airways during prolonged use.

Bull Nose and Nut: Connects the flow meter to the oxygen cylinder securely, often sealed with Teflon tape to prevent leaks.

Connecting Joint and Outlet: Allows attachment of oxygen tubing or nasal cannula for patient delivery.
