Embodiment 1

[0040] Embodiment one, with reference to Figure 1-6 : Mask-type exhalation collection device, comprising:

[0041] A mask 1 provided with an exhalation hole 13 and an air inlet 14, the exhalation hole 13 is fixedly provided with an outer one-way valve or an outer one-way ventilation valve, and the outer one-way valve or the outer one-way ventilation valve is arranged on the mask 1 On the outer surface of the mask 1, the air inlet 14 is fixedly provided with an inner one-way flap or an inner one-way ventilation valve, and the inner one-way valve or the inner one-way ventilation valve is arranged on the inner surface of the mask 1, and the air inlet 14 is connected to the atmosphere or Oxygen cylinder, preferably, a filter screen cover 12 is provided in the pipeline connecting the air inlet 14 to the atmosphere or the oxygen cylinder, and the outer surface of the mask 1 is provided with a rubber strap 11, specifically, the rubber strap 11 is connected to the mask 1 through a bu...

Embodiment 2

[0055] Embodiment two, refer to Figure 1-4 In this embodiment, the first air pump 4 is provided on the basis of the first embodiment. For infants or unconscious patients, in order not to affect their exhalation, the first air pump 4 should be preferably provided. Specifically, the exhalation The air hole 13 is connected to the suction port of the first air pump 4 through a pipeline, and the exhaust port of the first air pump 4 is connected to the input end of the first three-way valve 3 through a pipeline. As for the filter device 2, the simple filter device 2 should be arranged in the pipeline connecting the exhalation hole 13 and the first air pump 4.

[0056] The mask-type exhalation collection method comprises the following steps:

[0057] S1. Gas separation: The first three-way valve 3 is continuously powered off through the single-chip computer, and the exhaled gas enters the first three-way valve 3, and then is transported to the atmosphere or the second collector thr...

Abstract

The invention discloses a face mask type exhaled air collection device, and belongs to the technical field of medical apparatus and instruments. The face mask type exhaled air collection device comprises a face mask provided with an exhaling hole and an air inlet, a first three-way valve, a second three-way valve, a first air collection mechanism, a second air pump and a third three-way valve, wherein the exhaling hole is connected with the input end of the first three-way valve, and exhaled air realizes air separation through the first three-way valve; one output end of the first three-way valve is connected with the input end of the second three-way valve, and alveolar air is conveyed through the second three-way valve; one output end of the second three-way valve is connected with the input end of the first air collection mechanism; the other output end of the second three-way valve is connected with the input end of the third three-way valve; and one output end of the third three-way valve is connected with the air exhaust hole of the second air pump. The invention puts forwards the face mask type exhaled air collection device so as to conveniently realize collection of the exhaled air of an infant or a patient who is unconscious.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a mask-type exhalation collection device and a method thereof. Background technique [0002] The human circulatory system exchanges substances through the alveoli and the respiratory system, so by detecting the human breathing gas, the internal environment of the human body can be detected indirectly. Compared with traditional diagnostic methods, respiratory diagnosis is faster, more convenient, non-invasive, and has less side effects. Therefore, breathing detection has received more and more attention. At present, respiratory diagnosis has been widely used clinically in the detection of Helicobacter pylori. [0003] Existing exhalation collection devices basically collect the exhaled gas by blowing through the mouth when people are awake. However, this method is difficult to effectively collect breath from unconscious patients or infants. Contents of the invention ...
