Description

CLAIM FOR PRIORITY This application is a continuation of U.S. patent application Ser. No. 17/737,829 filed on May 5, 2022 and titled “RESPIRATORY FLUID FLOW CONTROL DEVICE AND METHOD OF USING SAME,” (the “'829 Application”) which issued as U.S. Pat. No. 12,508,390 on Dec. 30, 2025. The '829 Application is herein incorporated, in its entirety, by reference. TECHNICAL FIELD The present disclosure relates generally to respiratory assist devices. More specifically, the disclosure relates to a respiratory fluid control device or adaptor for delivering oxygen to a patient and method of using the same. BACKGROUND Positive airway pressure therapies are used for the treatment of various respiratory conditions including both central apnea and obstructive apnea. During sleep or sedation, it is common in patients for the muscles that normally hold the upper airway open to relax so that airway tissues partially occlude or obstruct the airway, preventing adequate gas flow to the lungs. In many patients that are in a relaxed state such as sleeping or who have received sedative drugs, the muscles of the upper airways are relaxed to such an extent that any effort to inhale by the patient collapses the airway and obstructs gas flow restricting ability to draw in breathable gas. The negative pressure created as the patient tries to draw gas into the lungs pulls the airway closed even more, exacerbating the problem. Positive airway pressure (PAP) therapies use a tightly sealed breathing mask and a source of flowing breathable gas to create positive pressure in the airway. This positive pressure supports the airway opening such that it does not collapse as the patient inhales. The flow generator used for PAP must have sufficient flow to supply patient inhalation volume and compensate for any mask leak. The flow generator must also have sufficient positive pressure to counterbalance any negative pressures created by the patient during inhalation. Continuous positive airway pressure, or CPAP, is a specific PAP therapy that continuously applies a specific prescribed pressure to the airways throughout every cycle of the breath. CPAP forces the airway to stay open during inhalation so that breathable gas can pass freely into the lungs on demand even when the airway opening is relaxed. SUMMARY OF DISCLOSURE According to the present disclosure, an adaptor for generating flow comprises: an adaptor housing body, the adaptor housing body comprising a distal end and an open proximal end for attachment to a patient interface; the distal end of the adaptor housing body having an oxygen inlet, the oxygen inlet comprising a coupler on an exterior side for connection to an oxygen source to convey pressurized oxygen from a pressurized oxygen source in connection with the coupler to the adaptor; the oxygen inlet extending into an interior of a distal air intake portion, and the oxygen inlet having a nozzle with at least two apertures for directing oxygen into an interior of a distal air intake portion; and the distal air intake portion comprising at least one air inlet port to allow air to be drawn into the interior of the distal air intake portion, and a flow-resisting media covering at least a portion of the at least one air inlet port.
