Problems solved by technology

When the patient exhales, the exhaled gas passes through the inhalation port, which causes the pollution of the inhalation path in the three-way tube, and the three-way tube is used repeatedly. When other patients use the three-way tube to inhale again, the clean gas will be released. It is inhaled into other patients through the contaminated path, so the test population will have a great risk of mutual infection when testing

Embodiment Construction

[0030] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0031] Such as Figure 1~2 As shown, a tidal breath collection system includes a face mask 1, a three-way joint 2, an exhalation collection air bag 3, and an inhalation air bag 4. The face mask 1 is connected to one end of the three-way joint 2, and the three-way joint The other two ends of the exhalation collection air bag 3 and the inhalation air bag 4 are respectively connected, and it is characterized in that: the inhalation ai...

Abstract

The invention provides a tidal breathing collection system and method. The tidal breathing collection system comprises a face mask, a three-way joint, a breathing collection air bag and an inspirationair bag, wherein the face mask is connected with one end of the three-way joint, and the other two ends of the three-way joint are respectively connected with the breathing collection air bag and theinspiration air bag; the inspiration air bag is provided with an air outlet end and an air inlet end; and an air outlet check valve is arranged at the air outlet end, and an air inlet check valve isarranged at the air inlet end. According to the tidal breathing collection system, the check valves are arranged at two ends of the inspiration air bag, and are connected with the three-way joint through hoses, so that inhaling and exhaling paths are separated; when a subject uses the system, a washed clean gas is inhaled by the subject through the air outlet end with the air outlet check valve, an air pipe and the three-way joint, and the gas exhaled by the subject is collected into the inspiration collection air bag through the three-way joint and the air pipe, the three-way joint having a common path for inhaling and exhaling is disposably used by single person, and the possibility of cross infection is avoided.

Description

technical field [0001] The invention relates to the field of gas sampling, in particular to a tidal breath collection system and method. Background technique [0002] By collecting tidal breath gas components and measuring their concentrations, doctors can assist doctors in diagnosing patients' diseases, monitoring disease states and observing treatment effects, etc. [0003] Tidal nitric oxide is used for the diagnosis and monitoring of respiratory system inflammation. This is because the endogenous gas signal molecule NO is produced by the oxidative deamination of arginine in cortical cells. Infection, allergies, trauma and other inflammatory factors can be induced by increasing The expression of NO synthase leads to a significant increase in NO concentration, which can be quantified by exhaled breath analysis. Pulmonary inflammatory diseases that lead to increased eNO include: bronchial asthma, upper respiratory tract viral infection, bronchiectasis, and fibrosing alveol...
