Nasal patient interface arrangement for transporting breathing gas
A recently granted patent (Publication Number: US11771860B2) describes a nasal patient interface arrangement for delivering breathing gas to a patient. The arrangement includes an inspiratory air conduit, a nose adapter, and a valve arrangement. The valve arrangement controls the passage of gas through a first bidirectional gas passage and can be piloted between a deflated state and an inflated state. When the valve is inflated, the first gas passage is at least partially blocked to prevent the passage of gas. The arrangement also provides a second bidirectional gas passage connected to the inspiratory air conduit, nose adapter, and first gas passage. The valve arrangement is enclosed in the first gas passage and is connected to a pneumatic unit via a gas delivery passage. The valve arrangement is automatically inflated when breathing gas is provided through the inspiratory air conduit and second gas passage to the nose adapter.
The valve arrangement includes a tubular shaped valve element, such as a balloon valve, that seals the first bidirectional gas passage when inflated. In the deflated state, the balloon valve allows air to pass from the nose adapter to the ambient air through the first gas passage. In the inflated state, the balloon valve prevents air passage from the nose adapter to the ambient air. The gas delivery passage delivers gas to the inside of the balloon valve, allowing it to inflate.
The arrangement also includes a pressure measuring tube in fluid connection with the second bidirectional gas passage. The gas delivery passage and/or pressure measuring tube can be arranged alongside or inside the inspiratory air conduit. The nose adapter includes at least one prong that can be inserted into the nostril of the nose. The valve arrangement is situated at a distance of less than 2 cm from the nose when the nose adapter is connected.
The patent also describes a breathing apparatus that includes the nasal patient interface arrangement. Additionally, a method for operating the breathing apparatus is outlined. The method involves inflating the valve in the first gas passage, providing breathing gas through the second gas passage to the nose adapter during inhalation, and deflating the valve to allow the majority of exhaled gas to pass through the first gas passage to the ambient air during exhalation.
Overall, this patent describes a nasal patient interface arrangement that efficiently delivers breathing gas to a patient while controlling the flow of gas through a bidirectional gas passage. The arrangement includes a valve arrangement that can be automatically inflated and deflated based on the inhalation and exhalation of the patient.
