HANDHELD THERAPEUTIC GAS DELIVERY

摘要

A nozzle apparatus for dispensing an adjustable combination of gas, having a nozzle outlet adjustably combined with a delivery component. The nozzle outlet may have a groove for receiving a roll pin; and an inner lumen comprising a cylindrical shaft having a diameter between 5/1000ths and 20/1000ths of an inch. The delivery component configured to receive air from the nozzle outlet, may have a first circular ambient air hole having a diameter, and a second circular ambient air hole having the same diameter as the first ambient air hole, and a removable plugging device covering the second circular ambient air hole. The delivery component may be adjustable in orientation with respect to the nozzle outlet, and may be adjustable to vary a concentration of therapeutic gas delivered to a patient.

主权项

1. A nozzle apparatus for dispensing an adjustable combination of gas, the nozzle apparatus comprising:
a roll pin; a nozzle outlet comprising:
a groove for receiving the roll pin, wherein the groove is disposed along at least a portion of the perimeter of the nozzle outlet and configured to allow rotation of the nozzle outlet about its lengthwise axis and relative to the roll pin; andan inner lumen comprising a cylindrical shaft having a diameter between 5/1000ths and 20/1000ths of an inch; a triggering device configured to be movable from an unactuated first position to an actuated second position, wherein gas is permitted to flow through the inner lumen when the triggering device is moved to the actuated second position; a spring member operably connected to the triggering device and configured to urge the triggering device towards the unactuated first position, wherein a user of the nozzle apparatus must exert a force to oppose the urging force of the spring member to move the triggering device from the unactuated first position to the actuated second position; and a delivery component configured to receive gas from the nozzle outlet, the delivery component comprising:
a first circular ambient air hole;a second circular ambient air hole; andone or more removable plugging devices covering the ambient air holes.
