Description

Technical Field

[0001] The utility model relates to the technical field of breath analyzers, in particular to a breath sampling device. Background Art

[0002] Exhaled breath sampling is used for the diagnosis and monitoring of respiratory inflammation, and exhaled carbon monoxide is used for the diagnosis and monitoring of respiratory and circulatory system diseases. Inflammatory factors such as infection, allergy, and trauma can increase the expression of inducible NO synthase and heme oxygenase, resulting in a significant increase in NO and CO concentrations, which can be quantitatively measured through exhaled breath analysis.

[0003] During the use of the exhaled breath sampling device, the patient may be located at a distant location due to different environments. During use, the pipeline itself is at a standard height, and it is difficult to adjust the expanded length of the pipeline according to usage requirements, resulting in poor flexibility of the equipment during operation. After the pipeline completes the collection, the sampling device lacks a respiratory mask positioning structure, and personnel can easily place the respiratory mask directly on the surface of the device, which can easily cause the virus to infect the surface of the respiratory mask. Summary of the invention

[0004] The purpose of the utility model is to provide a breath sampling device to solve the above-mentioned defects caused by the prior art.

[0005] A breath sampling device includes a sampling vehicle body, a test tank body is arranged directly above the sampling vehicle body, a lifting pipe is connected through the top of the test tank body, a storage mechanism is arranged inside the test tank body, the storage mechanism unfolds and stores the sampling pipeline to avoid the pipeline being unable to be stored or adjusted in length in time after use, and a test mechanism is arranged on the top of the storage mechanism, the test mechanism tests the material and stores and compares the data of carbon monoxide.

[0006] Preferably, the testing mechanism includes an air chamber, an air intake pipe, a CO sensor, a solenoid valve and a CO filter. The air chamber is arranged inside a sampling vehicle body, and an air intake pipe is connected to the outside of the air chamber. One end of the air intake pipe is connected to the input end of the CO sensor, the discharge end of the CO sensor is connected to the input end of the solenoid valve, and the output end of the solenoid valve is connected to the input end of the CO filter.

[0007] Preferably, the CO sensor is connected to the tail end of the air supply hose via an air intake pipe connected to the input end.

[0008] Preferably, the storage mechanism includes an air supply hose, a gear roller, a reset spring, a guide rail and a spur gear bar. The outer side of the air supply hose is wrapped and connected with a gear roller, the bottom end of the gear roller is connected with a spur gear bar, the outer side of the spur gear bar is connected to the outer side of the guide rail, the tail end of the spur gear bar is welded with the top end of the reset spring, the tail end of the reset spring is connected to the inner end of the guide rail, and the guide rails are symmetrically distributed at the inner end of the test tank body.

[0009] Preferably, the air supply hose is connected to the top of the lifting pipe through an exhalation mask that penetrates through the top.

[0010] Preferably, the top bearing of the test tank body is connected to the bottom end of the display screen.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The operator engages the bottom end of the gear roller with the spur gear. During use, when the air supply hose is pulled by the operator, the gear roller drives the spur gear set at the bottom to engage and move the material, and pulls the bottom end of the spur gear through the reset spring to adjust the release length of the pipeline.

[0013] 2. After the sampling of exhaled breath is completed, the air supply hose is loosened to allow the straight tooth bar to retract inward, thereby driving the gear roller to rotate in the opposite direction to store the hose. This prevents the patient from putting the breath mask on after the sampling is completed, causing harmful viruses to directly contaminate the breathing mask and the required pipelines. At the same time, it is convenient to connect the disposable breathing mask to the pipeline and quickly disassemble the breathing mask. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In this embodiment, the testing mechanism 6 includes an air chamber 7, an air intake pipe 8, a CO sensor 15, a solenoid valve 16 and a CO filter 17. The air chamber 7 is arranged inside the sampling vehicle body 1, and the air intake pipe 8 is connected to the outside of the air chamber 7. One end of the air intake pipe 8 is connected to the input end of the CO sensor 15, the discharge end of the CO sensor 15 is connected to the input end of the solenoid valve 16, and the output end of the solenoid valve 16 is connected to the input end of the CO filter 17. The exhaled gas is sensed and the data is calibrated by the CO sensor 15.

[0024] In this embodiment, the CO sensor 15 is connected to the tail end of the air supply hose 10 via the air intake pipe 8 connected to the input end, and the CO sensor 15 collects data of the input gas.

[0025] In this embodiment, the storage mechanism 9 includes an air supply hose 10, a gear roller 11, a reset spring 12, a guide rail 13 and a spur gear 14. The outer side of the air supply hose 10 is wrapped and connected with the gear roller 11, the bottom end of the gear roller 11 is connected to the spur gear 14, the outer side of the spur gear 14 is connected to the outer side of the guide rail 13, the tail end of the spur gear 14 is welded with the top of the reset spring 12, the tail end of the reset spring 12 is connected to the inner end of the guide rail 13, and the guide rail 13 is symmetrically distributed at the inner end of the test tank body 2. The outer side of the spur gear 14 is positioned and guided by the guide rail 13 to avoid displacement of the spur gear 14.

[0026] In this embodiment, the air supply hose 10 is connected to the top of the lifting pipe 3 through the exhalation mask 4 connected through the top, and the bottom end of the exhalation mask 4 is positioned by the lifting pipe 3 to prevent the exhalation mask 4 from displacement.

[0028] In practical application, this breath sampling device includes the following work contents:

[0029] Step 1: The operator directly connects the disposable breathing mask 4 to the top of the air intake pipe 8. During use, the air intake pipe 8 provided on one side can be pulled so that the air intake pipe 8 is pulled out along the inside of the lifting pipe 3, and the outer side of the spur gear 14 is rotated and pulled by the gear roller 11 so that the spur gear 14 slides through the outer side of the guide rail 13. At the same time, the return spring 12 is adjusted according to the position of the spur gear 14 to adjust and control the length of the air intake pipe 8 released by the gear roller 11;

[0030] Step 2: The operator uses the exhalation mask 4 to guide the exhaled gas into the passage of the air supply hose 10, and injects the gas into the interior of the air intake pipe 8 through the air supply hose 10, and directly guides the gas into the CO sensor 15 provided in the air chamber 7 through the air intake pipe 8.
