Description

Gas breathing filter device

Technical Field

The utility model relates to the field of respiratory system disease detection equipment, in particular to a gas breathing filtering device.

Background

Exhaled NO has been used for routine detection of respiratory diseases as an internationally recognized marker of non-invasive airway inflammation. The national thoracic society of America (ATS) and European Respiratory Society (ERS) established international technical standards for exhaled NO determination in 2005, requiring subjects to use disposable bacterial viral filters, first inhale air with NO content below 5ppb, then exhale at a constant pressure of 5-20cmH2O, while preventing air leakage throughout exhalation and inhalation, ensuring the safety and effectiveness of exhalation tests.

Since expiratory NO is related to expiratory flow rate and is easily disturbed by nasal air, the standardized expiratory nitric oxide measurement method recommended by ATS/ERS for measuring inflammation in the lower respiratory tract requires a single continuous expiration of 10 seconds (or 6 seconds in children) at a fixed expiratory flow rate of 50ml/s at an expiratory pressure of at least 5cmH 2O.

The most direct method for exhaling at a constant flow rate is realized by measuring and indicating the expiratory flow rate, and then an exhaler autonomously adjusts the expiratory force through an indicated feedback signal, and in the practical application process, the expiratory flow rate is continuously controlled within the range of 45-55 ml/s within 2-3 seconds, or is difficult to control.

For the children and the patients with serious diseases who can not control breathing autonomously, a tidal breathing method is required to be used for sampling and analyzing, compared with a standard expiratory nitric oxide sampling and analyzing method, the tidal breathing method relates to higher expiratory flow rate, shallower breathing and shorter breathing time period, and whether repeated and reliable data with clinical guidance significance can be obtained under the condition is always a hot point of concern in the industry.

At present, the prior art mainly adopts a straight barrel type handle, the air passage of the handle is longer, the filter cavity is also slender, the air resistance of the air sucked from the outside is large, the whole air blowing process is not consistent easily during air blowing, the air blowing fails, and when the face mask is additionally arranged on the air blowing handle during straight barrel operation, a patient needs to lower the head to blow air, which is not in line with human engineering.
