Product Features:
The disposable pulmonary function meter filter is a filter device that connects the subject and the pulmonary function instrument, and is used to assist the patient in checking, diagnosing and treating pulmonary function. The air exhaled by the subject passes through the filter to filter out the saliva when blowing, effectively preventing the occurrence of cross-infection; one-time use can also reduce the loss of pulmonary function instruments and improve the efficiency of pulmonary function testing.
Features:
The product is made of medical-grade polymer materials and uses imported filter cotton for multi-layer filtration. It is disposable and can effectively prevent cross-infection.
Product performance:
● Microbial filtration rate: not less than 95%.
● Particle filtration efficiency (PFE): When the gas flow is 30L/min, the filtration efficiency of the disposable pulmonary function meter filter for particles larger than 0.3μm in diameter should be no less than 99.99%.
● Air flow resistance: When the gas flow rate is 30L/min, the air flow resistance of the disposable pulmonary function meter filter is not greater than 20Pa.
● Sealing: It has good sealing. When maintaining the pressure of 7kpa±0.15kpa, the gas leakage rate does not exceed 25ml/min.
Scope of application:
The product range is complete and can be used for commonly used pulmonary function meters in the market such as Kangxun, Yeager, Cosimai, Zekang and many other brands.
