The adjustable venturi mask is made according to the venturi principle, that is, oxygen enters the mask through a narrow hole to generate a negative pressure around the jet stream, carrying a certain amount of air from the open edge into the mask, and the size of the mask slit changes the air. The ratio to oxygen. Since the airflow injected into the mask is greater than the maximum flow rate and tidal volume when the patient inhales, the oxygen concentration is constant, because the gas with high flow rate continuously flushes the inside of the mask, and it is difficult to tribute in the mask in the exhaled air, so there is basically no repetitive breathing. Patients with hypoxemia with hypercapnia need to choose a venturi inner cover to accurately control the aerobic concentration.

Adjustable venturi mask operation instructions

1. When using oxygen as the gas source, please check whether the humidification bottle leaks, so as to avoid the atomization failure caused by insufficient air pressure. If the air source uses a small diameter special output connector, please contact the supplier for a product with a suitable air pipe connector.

2. Cover the top cover so that it fits comfortably with the patient's face and is secured with an elastic band. Adjust the aluminum clip so that the mask is in close contact with the face to prevent oxygen from entering the eye.

3. Unscrew the atomization cover, add the liquid according to the doctor's advice, then install the atomization cover, and screw it down to the right. Insert the nebulizer into the mask and connect the air supply with the connecting tube.

4. Turn on the air supply and adjust the gas flow to 4L/min~10/min. If necessary, tap the nebulizer until it starts to atomize.

Adjustable Venturi mask operation precautions

1. The amount of charge should not exceed the large capacity of the zui specified by the atomizer (see specifications). Do not inject the solution into the small hole in the center of the atomizer when adding the drug.

2, in cold and wet weather, do not go outside immediately after atomization treatment, otherwise it is easy to catch a cold.

3. If the patient feels nausea, cut off the small vents on both sides of the mask.

Cleaning and disinfection

1. Disassemble the atomizer and rinse the parts with running water.

2. If disinfection is required, use a disinfectant suitable for plastics, such as medical alcohol.
