510(k) Summary of Safety and EffectivenessSechrist Industries, Inc., 3300E/ER Hyperbaric ChamberDevice DescriptionThe Model 3300E/ER Hyperbaric Chamber is a monoplace (one patient) pressurechamber designed to administer 100% oxygen at pressure greater than ambient, up to 3atmospheres absolute (30 psi) of pressure.The Model 3300E/ER Hyperbaric Chamber is constructed with a horizontal seamlessacrylic inner cylinder. One end is equipped with a hard anodized aluminum cover andthe other with a hard anodized aluminum door assembly, with access ports available forpatient support (such as patient monitoring and delivery of intravenous fluids). Thecontrol system is pneumatic/electronic containing the controls, indicators, chamberpressure display gauges, and intercom assembly.Summary of Substantial EquivalenceThe design features and materials used in the manufacture of the Sechrist Industries, Inc.3300E/ER Hyperbaric Chamber are substantially equivalent several pre-amendmentproducts. Additionally the 3300E Hyperbaric Chamber is of similar shape andfunctionality to the predicate device.Therefore, due to the similarity of design features, materials, test results and the similarityof the indicated use to other pre-amendment devices and the predicate device , SechristIndustries, Inc. believes this product does not have any safety or efficacy issues.3
