Direct Dose Sealflex Adult Large Mask for Lung Ventilation Studies

In addition to the patient comfort provided by the soft, pliable air cushion of the disposable face mask, the direct dose features reduced patient anxiety because no needle is used. The syringe luer locks tightly to the direct dose tube, away from the patient’s face. The one-way valve prevents the gas from reversing trough the mask luer connector, allowing the technologist to disconnect immediately after injecting. Sold in multiples of 25. This product is non returnable.
