This device is used to detect the respiratory rate accuracy of the end of breath carbon dioxide monitoring part in a multi-parameter monitor or a separate end of breath carbon dioxide monitor. In combination with different concentrations of carbon dioxide standard gases, it can also detect the accuracy of the carbon dioxide concentration of the tested device. This device can detect both sidestream sampling type carbon dioxide monitors and mainstream sampling type carbon dioxide monitors. The equipment is easy to operate and has a small size, making it easy for measurement units to carry out testing work outside. The quality inspection departments of monitor manufacturers, ventilator and anesthesia machine manufacturers can also use this equipment for internal testing of production line machines.
Main technical parameters:
1. Respiratory rate setting range: 3-120BrPM, respiratory rate output accuracy: ± 0.5%
Respiratory frequency resolution range (based on the resolution ability of the monitor): 3-75BrPM, accuracy: ± 1 BrPM
2. Breathing (exhaling) time: 0.1-20 seconds, inhalation to exhalation ratio: 1:1/1:2/2:1, continuously adjustable
The 3 standard gas inlet is Φ 8mm hose quick connector, standard gas outlet base Φ External 22mm/internal 15mm standard ventilator pipe joint
4 manual mode: standard gas can continuously output, used for standard gas concentration detection.
Secondary pressure reducing valve components: high-pressure gauge range of 25MPa, low-pressure gauge range of 0.15-0.2MPa, pressure reducing valve outlet connected to flow meter of 0.1-1.5L/min, outlet connected to Φ 8mm hose quick connector.
6. Input concentration range of carbon dioxide standard gas: Conventional is 5% volume percentage (standard gas is CO2 gas, balance gas is nitrogen, 8L aluminum bottle, equipped with a secondary pressure reducing valve).
