Abstract
The utility model discloses an expired gas collection device which comprises a three-way gas valve, a gas guiding pipe, a blowing nozzle and a gas collection bag, wherein two valve ports of the three-way gas valve are connected with the blowing nozzle and the gas collection bag respectively; and the other valve port of the three-way gas valve serves as a gas outlet and is connected with a detecting instrument. According to the expired gas collection device, expiratory volume can be controlled accurately; and convenience and accuracy in gas detection are improved.
Description
Technical field
The utility model relates to a kind of medicine equipment, particularly a kind of expiration gathering-device for collecting the human body breath.
Background technology
In the modern medical service field, be that disease surveillance or prevention all can be used human body expiration detection.Conventional detection method is that patient directly blows facing to detecting instrument.Accurate for what detect, usually begin Exhaled gasesS and can not advance detecting instrument as the gas sample, blow to instrument again behind a certain amount of gas of need to breathing out first and detect.Be difficult to accurately grasp the exhalation amount yet generally begin Exhaled gasesS, can only lean on experience, the accuracy that causes detecting has been subject to impact.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of expiration gathering-device.
The technical solution of the utility model is achieved in that and comprises threeway gas trap, wireway, blowing nozzle and gas collection bag, and sealing links to each other two valve ports of threeway gas trap with the gas collection bag with blowing nozzle respectively, and another valve port is done the gas outlet, for linking to each other with detecting instrument.
Described blowing nozzle be soft material make horn-like, be connected on the threeway gas trap by wireway.
Identification label is arranged to mark out particular capacity on the gas collection bag, be convenient to people and distinguish and select.The gas collection bag can be divided into plurality of specifications according to the capacity difference, and the gas collection bag of different size is packed together.
The beneficial effects of the utility model are: by the threeway gas trap blowing nozzle is communicated with the gas collection bag when carrying out the gas detection, making the beginning Exhaled gasesS is to enter the gas collection bag and do not enter detecting instrument, because the capacity of gas collection bag is certain, namely reach expiratory gas volume after blowing completely, and then adjustment threeway gas trap makes blowing nozzle communicate with the gas outlet, make follow-up Exhaled gasesS enter detecting instrument, guaranteed the accuracy that detects.
Description of drawings
Fig. 1 is the schematic appearance of the utility model expiration gathering-device.
Embodiment
By reference to the accompanying drawings the utility model is described further.
As shown in Figure 1, use threeway gas trap 3.One valve port of threeway gas trap 3 is connected with blowing nozzle 1 by wireway 2.Blowing nozzle 1 adopts rubber etc. to make than softwood matter, make horn-like, applying mouth surrounding skin when being convenient to exhale, preventing that air from sneaking into affects testing result.Another valve port of threeway gas trap 3 is connected with gas collection bag 5, and the gas collection bag 5 of different capabilities can be changed according to testing requirement.The 3rd valve port of threeway gas trap 3 connects detecting instrument as the gas outlet by another root wireway 6.
Identification label is arranged to mark the capacity of gas collection bag, the requirement that detects to adapt to all ages and classes section or different crowd gas on the gas collection bag 5.The gas collection bag can be divided into multiple according to the capacity difference, and packs as one group take different capabilities gas collection bag.
For example generally need to breathe out first for the adult and just can detect behind the gas of 300ml, can be connected to 300ml gas collection bag 5 on the threeway gas trap 3 this moment, adjustment threeway gas trap 3 makes blowing nozzle 1 be communicated with gas collection bag 5 and disconnects with wireway 6, by blowing nozzle 1 and wireway 2, threeway gas trap 3 is exhaled and is arrived gas collection bag 5, until the gas collection bag 5 full 300ml that are, and then adjust wireway 6 that threeway gas trap 3 is communicated with blowing nozzle 1 to be connected with detecting instrument and with 5 disconnections of gas collection bag, by gas collection mouth 1, wireway 2, threeway gas trap 3 and wireway 6 are blown to detecting instrument and are carried out the gas detection.And for children because the 200ml gas of only need to breathing out first, then to change capacity into be getting final product of 200ml to gas collection bag 5.
Claims (3)
1. an expiration gathering-device is characterized in that comprising threeway gas trap, wireway, blowing nozzle and gas collection bag, and sealing links to each other two valve ports of threeway gas trap with the gas collection bag with blowing nozzle respectively, and another valve port is done the gas outlet, is used for linking to each other with detecting instrument.
2. expiration gathering-device according to claim 1 is characterized in that: described blowing nozzle be soft material make horn-like, be connected on the threeway gas trap by wireway.
3. expiration gathering-device according to claim 1, it is characterized in that: described gas collection bag by measure size is divided into different size, and the gas collection bag of different size is packed together.
