Problems solved by technology

[0003]13C infrared spectrometer is suitable for clinical medical diagnosis and analysis of sample gas in 13C urea breath test samples 13C abundance exceeds the change amount DOB(‰) of the bottom gas 13C abundance to determine whether the subject is infected with Helicobacter pylori (Hp), 13 C Infrared spectrometer matching exhalation sampling bag can be used to collect the gas exhaled by the tester. It is a necessary special consumable. However, the air blowing port of the current sampling bag is not equipped with a device to prevent gas backflow, and the gas is easy to flow out. The concentration of substances contained in the gas will also change accordingly, and there is no corresponding spectrometer anti-pollution device

Embodiment 1

[0017] Such as figure 1 , 2 As shown, a breathalyzer sampling bag includes an air storage bag 1 and an air blowing nozzle 2, the air storage bag 1 is connected to the air blowing nozzle 2, and an elastic The plastic baffle 3, the plastic baffle 3 is oval, the plastic baffle 3 and the blowing nozzle 2 are at an angle of 15 degrees, the upper end of the plastic baffle 3 with a longer diameter is connected to the inner wall of the blowing nozzle 2, and the lower end is close to the inner wall , the width of the plastic baffle 3 is the same as the inner diameter of the blowing nozzle 2, a plastic tube 4 is arranged at the opening of the blowing nozzle 2, the outer diameter of the plastic tube 4 is the same as the inner diameter of the blowing nozzle 2, and the plastic tube 4 extends into the blowing nozzle The inside of the mouth 2 is 1.5cm. When blowing air, the plastic flap 3 can spring open, and the airflow enters the air storage bag 1. When the blowing stops, the plastic flap...

Embodiment 2

[0019] Such as image 3 As shown, the rest are the same as in Embodiment 1, the difference is that the middle part of the plastic tube 4 is set as a wrinkled telescopic structure 5, and this setting can change the length of the plastic tube 4 at will according to the needs of the tester, and the plastic tube 4 A circular water-absorbing filter paper 6 is connected inside, and the diameter of the circular water-absorbing filter paper 6 is the same as the inner diameter of the plastic tube 4, which can absorb part of the moisture and saliva in the exhaled breath of the tester, reduce the influencing factors of detection, and prevent the pollution of the instrument.

Abstract

The invention discloses a sampling bag for an expiration tester, and relates to the technical field of medical instrument. The sampling bag comprises an air storage bag and a blowing spout, wherein the air storage bag is connected with the blowing spout; an elastoplast separation blade is arranged inside the connection part of the air storage bag and the blowing spout; the plastic separation blade is ellipsoidal; an inclination angle of 15 degrees is formed between the plastic separation blade and the blowing spout; the upper end of the plastic separation blade in the longer diameter is connected with the inner wall of the blowing spout, and the lower end is tightly jointed with the inner wall; the width of the plastic separation blade is equal to the inner diameter of the blowing spout; a plastic tube is arranged at the opening part of the blowing spout; the outer diameter of the plastic tube is equal to the inner diameter of the blowing spout; the plastic tube extends into the blowing spout for 1.5 cm; the plastic separation blade can be knocked open and bounds back along with the starting and ending of blowing, so that air inside the air storage bag is prevented from flowing out; a person being detected can blow through the plastic tube, so that saliva of the person being detected is prevented from being in contact with the air inlet of the detecting instrument to prevent contamination.

Description

[0001] technical field [0002] The invention relates to the technical field of medical devices, in particular to a sampling bag for a breathalyzer. Background technique [0003] 13 C infrared spectrometer is suitable for clinical medical diagnosis and analysis 13 C urea breath test sample gas 13 C abundance exceeds confidence 13 The change amount DOB(‰) of C abundance is used to judge whether the subject is infected with Helicobacter pylori (Hp), 13 C infrared spectrometer matching exhalation sampling bag can be used to collect the gas exhaled by the tester, which is a necessary special consumable, but the air blowing port of the current sampling bag is not equipped with an anti-gas backflow device, the gas is easy to flow out, and the gas contains substances The concentration of the spectrometer will also change accordingly, and there is no corresponding anti-pollution device for the spectrometer. Contents of the invention [0004] The object of the present inventio...
