Disposable pulmonary function meter filters

Disposable pulmonary function meter filters

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 work of pulmonary function testing.
