Main purpose
The respiratory tract suction duct airflow resistance tester is mainly used to measure the airflow resistance of various respiratory ducts and is an important indicator for detecting the performance of various ducts.
technical indicators
1. Operating interface: Touch screen: 7-inch K600+core/dot matrix 65 color 800 * 480 resolution, Simplified Chinese,
Automatic operation test mode for various parameters of human-machine dialogue, real-time display of test data and automatic calculation of duct airflow resistance data. Automatically determine the test results and trigger an automatic alarm if they are not qualified.
2. The testing includes: nominal specifications, number of tests, printing settings, testing, pressure values, time, calibration and other functional settings.
(1) High precision pressure sensor, testing range: 0.01kPa-30kPa, error ≤± 1%. Resolution: 0.001kPa, error ≤ ± 0.002kPa.
(2) Flow output range: 0.1L-40L/min, adjustable to any setting.
(3) Test duration: 0.1s-100min, error ≤± 0.5s.
(4) Equipped with an onboard printer that can print test data.
3. The air resistance of the closed suction catheter meets the air resistance limits of different patient groups: the expected transmission capacity of adult suction catheter is ≥ 300/ml; the maximum air resistance limit is 0.03 [hPa/(L/min)], and the flow rate is 30L/min. The expected transmission capacity of the suction catheter for children is 50ml~300/ml; The maximum atmospheric resistance limit is 0.07 hPa/(L/min), and the flow rate is 15 L/min. The expected transmission capacity of the suction catheter for newborns is ≤ 50ml; the maximum atmospheric resistance limit is 0.4 hPa/(L/min), and the flow rate is 2.5 L/min.
4. Power supply: AC90V-240V/50Hz (adaptive wide voltage), overall power: 70W. Net weight: approximately 20kg.
