The Spirit 300 HAS will provide a source of supplemental oxygen for ambulatory home healthcare patients, by vaporizing 93% liquid oxygen and then dispensing it to the patient via an integral electronic conserving device. The Spirit 300 HAS is intended to be transfilled only by the In-X Corporation's Home-Away System. The Spirit 300 HAS is neither a life sustaining nor life supporting device.
The Spirit 300 HAS is a small, lightweight, liquid oxygen portable unit. The unit consists of a vacuum-insulated cryogenic dewar, a vaporizer coil, an economizer regulator, two pressure safety relief valves, a manifold, an electronic printed circuit board conserving device and a protective case. The dewar has a capacity and capability to store 0.3 liters of liquid oxygen. The vaporizer coil warms the oxygen gas to a suitable temperature, as it exits the dewar. Dependant on the flow selection setting, the manifold either delivers the gas to the conserving device PCB or delivers a 2 LPM continuous flow directly to the oxygen outlet. The continuous flow setting is labeled CF on the flow selector. The conserving device has equivalent setting for 1, 1.5, 2, 3, 4, and 5 LPM prescriptions. At the various conserving device settings, the outlet gas is delivered in quick pulse dosages just at the onset of patient inhalation. The amount of gas delivered (with each breath) is approximately 15 ml/LPM setting. The Spirit 300 HAS is filled from a concentrator liquefaction device.
The provided text is a 510(k) summary for the Spirit 300 HAS Portable Liquid Oxygen Unit. It describes the device and its intended use, but it does not contain any information regarding acceptance criteria or a study proving the device meets acceptance criteria.
The document is a regulatory submission for premarket notification, which focuses on demonstrating substantial equivalence to a predicate device rather than presenting performance criteria and validation study results in detail. While device performance in terms of flow settings is mentioned in the device description, specific acceptance criteria for these performances and the studies validating them are not provided in this summary.
Therefore, I cannot fulfill the request for information on acceptance criteria and the study that proves the device meets them based on the provided text.
§ 868.5655 Portable liquid oxygen unit.
(a)
Identification. A portable liquid oxygen unit is a portable, thermally insulated container of liquid oxygen that is intended to supplement gases to be inhaled by a patient, is sometimes accompanied by tubing and an oxygen mask. An empty portable liquid oxygen unit is a device, while the oxygen contained therein is a drug.(b)
Classification. Class II (performance standards).
