A kind of alveolar expired gas catcher, comprise a gas dosing air bag, the air inlet side of gas dosing air bag is connected with connection tube by clapper, the end connector of connection tube is containing pipe, the sidewall of connection tube has one or two gas collecting mouth, gas collecting mouth is provided with gas collecting mouth switch, the side of giving vent to anger of gas dosing air bag arranges gas outlet, gas outlet is provided with gas outlet's switch.
Description
Technical field
This utility model belongs to clinical medicine auxiliary implement field, is specifically related to a kind of clinical medicine for collecting the device of alveolar expired gas.
Background technology
Spontaneous pneumothorax is Pneumology Department common disease, and the essence of this disease is bronchopleural fistula, and the air namely sucked, through bronchus-alveolar, by the cut of visceral pleura or/and duct enters pleural space, gathers at pleural space, causes a series of pathophysiology abnormal.The mist that IA gas is made up of multiple gases such as oxygen, carbon dioxide, nitrogen.After pneumothorax occurs, IA gas enters pleural space by the cut of visceral pleura, after visceral pleura cut is closed, enter various pure gas in pleura intracavity gas, such as oxygen, carbon dioxide dividing potential drop will change, and occur difference with IA oxygen, partial pressure of carbon dioxide.Diagnose clinically at present both at home and abroad spontaneous pneumothorax all with x-ray chest radiograph or Thoracic CT scan result for standard, but whether the cut of visceral pleura closes, and decides clinician and takes which type of method, implements treatment to patient.
Utilize partial pressure to measure at present and judge that the method whether visceral pleura cut closes has: compare partial pressure of oxygen, the partial pressure of carbon dioxide difference in the intrathoracic gas in pneumothorax side and patient's arterial blood gas simultaneously, the method need extract the arterial blood of patient repeatedly, bring very large misery to patient, sometimes also can be extracted into venous blood by mistake.In addition, the relation under pulmonary disease state in arterial blood in partial pressure of oxygen and partial pressure of carbon dioxide and alveolar gas and normal person different, therefore judging that whether closed pneumothorax side visceral pleura is scientific poor.
Utility model content
This utility model object provides a kind of safe, reliable, gathering-device of implementing simple alveolar expired gas, and the gas specimen obtained to collect noinvasive device replaces the ABS having now wound.
This device is the difference of the partial pressure of oxygen (PO2) utilized in Thoracic gas and alveolar breath, partial pressure of carbon dioxide (PCO2), judge whether the visceral pleura cut of pneumothorax side closes, thus instruct doctor to take science, reliable Therapeutic Method.
The alveolar expired gas catcher that this utility model provides, comprise a gas dosing air bag, the air inlet side of gas dosing air bag is connected with connection tube by clapper, the end connector of connection tube is containing pipe, the sidewall of connection tube has one or two gas collecting mouth, gas collecting mouth is provided with gas collecting mouth switch, the side of giving vent to anger of gas dosing air bag arranges gas outlet, gas outlet is provided with gas outlet's switch.
The volume of described gas dosing air bag is 400ml.Individual event flap between gas dosing air bag and connection tube controls gas can only enter metering air bag, and the gas measured in air bag can not enter in connection tube.
Advantage of the present utility model and good effect:
This utility model structure is simple, practical, safety, to patient's fanout free region.In the alveolar breath specimen got, oxygen and carbon dioxide dividing potential drop real result is reliable, the foundation that can judge as the state of an illness of the diseases such as pneumothorax and evaluate.
Accompanying drawing explanation
Fig. 1 is alveolar expired gas catcher.
In figure, 1. suck pipe, 2. gas collecting mouth switch, 3. gas collecting mouth, 4 connection tubes, 5. clapper, 6. gas dosing air bag, 7. gas outlet's switch, 8 gas outlets.
Detailed description of the invention
Embodiment 1:
As shown in the figure, the alveolar expired gas catcher that this utility model provides, comprise a gas dosing air bag 6, the air inlet side of gas dosing air bag is connected with connection tube 4 by clapper 5, the end connector of connection tube is containing pipe 1, and the sidewall of connection tube has one or two gas collecting mouth 3, gas collecting mouth is provided with gas collecting mouth switch 2, the side of giving vent to anger of gas dosing air bag arranges gas outlet 8, gas outlet is provided with gas outlet's switch 7.
The volume of described gas dosing air bag is 400ml.Individual event flap between gas dosing air bag and connection tube controls gas can only enter metering air bag, and the gas measured in air bag can not enter in connection tube.
Concrete operations are as follows:
After clamping patient nostril with nose clip, patient shuts up containing pipe with sucking, and " as blowing the trumpet " blows, and gas enters gas dosing air bag by connection tube and the clapper that communicates with it, when the breath in air bag reaches 400ml, then what breathe out has been exactly IA gas.Now, oral cavity, in conductive airways and the IA gas of part breathe out.By the gas of connection tube, acquisition port extracts expired gas 20ml, censorship under the state that is hedged off from the outer world.
The main points of this device are that the breath of 1. patient is breathed out in air by the outlet of this device.2. the gas entering clapper far-end can not reflux return in connection tube.
Claims (2)
1. an alveolar expired gas catcher, it is characterized in that this catcher comprises a gas dosing air bag, the air inlet side of gas dosing air bag is connected with connection tube by clapper, the end connector of connection tube is containing pipe, the sidewall of connection tube has one or two gas collecting mouth, gas collecting mouth is provided with gas collecting mouth switch, the side of giving vent to anger of gas dosing air bag arranges gas outlet, gas outlet is provided with gas outlet's switch.
2. alveolar expired gas catcher according to claim 1, is characterized in that the volume of described gas dosing air bag is 400ml; Individual event flap between gas dosing air bag and connection tube controls gas can only enter metering air bag, and the gas measured in air bag can not enter in connection tube.
