    • A test accessory for testing a variety respirators. The accessory is designed to compliment existing equipment to provide a robust assessment of respirator performance. The accessory may include a head form having an inflatable bladder capable of fitting a variety of sizes of respirator masks. In some embodiments, the inflatable bladder does not rely on adhesives to effect a seal, thereby eliminating manufacturing and quality assurance steps. The test accessory may also include a detachable instrumentation module that may be removed from the accessory, enabling calibration and maintenance at a remote facility without need for transporting the entire unit. The module may also house a memory device that may be upgraded with calibration data and firmware during the calibration process.
    • 用于测试各种呼吸器的测试附件。 该附件旨在补充现有设备,以提供对呼吸机性能的可靠评估。 附件可以包括具有能够适应各种尺寸的呼吸面罩的可充气囊的头部形式。 在一些实施例中,可充气囊不依赖于粘合剂来实现密封,从而消除制造和质量保证步骤。 测试附件还可以包括可以从附件移除的可拆卸的仪表模块,使得能够在远程设备上进行校准和维护,而不需要传输整个单元。 该模块还可以容纳可以在校准过程期间用校准数据和固件升级的存储器设备。
