Description
Technical Field
The utility model belongs to the field at medical instrument, concretely relates to expired gas input device.
Background
Currently, changes in the content of some elements in blood are clinically associated with liver, brain, kidney, stomach, duodenum, oral cavity, and lung dysfunction. When the levels of some elements in the blood are higher than the concentrations of hydrogen, methane, hydrogen sulfide, carbon dioxide, carbon monoxide and nitric oxide in the air, they diffuse from the blood into the lungs and emerge in the exhaled breath. Therefore, the exhaled gas can be used as a biomarker of various diseases and metabolic processes, so that the method replaces blood detection and provides a noninvasive diagnosis means for clinic. In recent years, the change in the composition of breath has been used to detect a number of physiological conditions, such as detection of helicobacter pylori infection, detection of small intestine bacterial overgrowth, detection of dyspepsia, detection of carbohydrate intolerance, evaluation of hepatic reserve function, and the like.
However, currently, the exhaled breath is directly exhaled into the detection instrument, and the patient must exhale in real time during the detection, and for the elderly, infants and other patients who are inconvenient to move or cannot fully follow instructions, the patient cannot exhale into the gas detection instrument in real time according to clinical needs.
In view of this, the present invention is especially provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an expired gas input device has solved the unable problem of exhaling to detecting instrument in as required of part patient.
In order to achieve the above object, the utility model provides a exhaled air input device, including exhaled air storage bag and gas analyzer interface, exhaled air storage bag is equipped with the check valve, the outside of exhaled air storage bag is connected with the storage bag interface in the check valve department, inside exhaled air storage bag is covered with the check valve pellicle on the check valve; the gas analyzer is characterized in that a probe is arranged in the gas analyzer interface and used for jacking the one-way valve film sheet, and a plurality of gas inlet holes are formed in the gas analyzer interface and around the probe.
Furthermore, the membrane sheet of the one-way valve is fixed on the one-way valve through a membrane sheet fixing device.
Further, the probe is fixed in the gas analyzer interface by a probe fixing device.
Furthermore, one side of the gas analyzer interface, which is far away from the exhaled gas storage bag, is connected with a luer interface, and the luer interface is used for connecting the gas analyzer interface with a gas analyzer.
Preferably, the probe is located within the gas analyzer interface at a central location proximate a side of the exhaled gas storage bag.
The utility model provides a pair of expired gas input device has following beneficial effect:
can store patient's expired gas, carry out analysis detection in expired gas transport to gas detection instrument, to the old man who moves inconveniently or can not obey the instruction completely or infant and so on patient, can not according to clinical needs exhale in real time to the condition in the gas detection instrument under, save expired gas in advance through expired gas input device, can accomplish expired gas's analysis and detection smoothly.

Detailed Description
In order to make the technical field better understand the solution of the present invention, the present invention will be further described in detail with reference to the following embodiments.
As shown in fig. 1, an exhaled gas input device comprises an exhaled gas storage bag 1 and a gas analyzer interface 5, can store exhaled gas of a patient, and convey the exhaled gas into a gas detection instrument for analysis and detection, and can store the exhaled gas in advance through the exhaled gas input device under the condition that the patient who is inconvenient to move or cannot completely obey instructions cannot exhale into the gas detection instrument in real time according to clinical needs, so that the analysis and detection of the exhaled gas can be completed smoothly.
Be equipped with a check valve on the expired gas storage bag 1, expired gas storage bag 1 is inside to be equipped with check valve film piece 2 in check valve department, 1 outside of expired gas storage bag is connected with storage bag interface 4 in check valve department, ventilate through opening of check valve film piece 2 between expired gas storage bag 1 and the storage bag interface 4, check valve film piece 2 passes through film piece fixing device 3 to be fixed in the inside check valve department of expired gas storage bag 1.
The central point that is close to expired gas storage bag 1 one side in gas analysis appearance interface 5 puts and is equipped with probe 6 for push up one-way valve film piece 2, and probe 6 passes through probe fixing device 7 to be fixed in gas analysis appearance interface 5, is equipped with a plurality of inlet ports 9 around probe 6 in gas analysis appearance interface 5 for the gas of circulation expired gas storage bag 1 to gas analysis appearance. One side of the gas analyzer interface 5, which is far away from the exhaled gas storage bag 1, is connected with a luer 8, and the luer 8 is a standardized micro non-seepage joint and is used for connecting the gas analyzer interface 5 with a gas analyzer and finally circulating the exhaled gas into the gas analyzer.
