Description

Technical Field

[0001] This utility model relates to the field of alcohol measurement technology, and in particular to a lung function and alcohol measurement device. Background Technology

[0002] Handheld spirometers are commonly used devices to assist traffic police in detecting drunk driving. Their working principle is as follows: the spirometer contains an electrochemical sensor. When alcohol molecules in a breath sample pass through this sensor, the alcohol is converted into acetaldehyde, releasing electrons in the process. These electrons cause a change in the current of the electrochemical sensor. The microprocessor then measures the current of the sensor to determine the alcohol content in the breath and converts it into a blood alcohol content value. This method offers the advantages of rapid and accurate measurement.

[0003] In the prior art, to facilitate driving safety, handheld lung capacity detectors are used to test before driving, which can effectively reduce the risk of drunk driving. However, the functions of alcohol measurement devices are relatively simple and cannot meet the needs of users, so they fail to attract consumers' attention. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing alcohol measuring devices, which have limited functionality and fail to meet user needs, thus failing to attract consumer attention. This invention provides a lung function and alcohol measuring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lung function and alcohol measurement device includes an alcohol detector and a spirometer, wherein the alcohol detector has a blowing tube at its top, and further includes:

[0007] A connecting block, which is fixed to the side of the spirometer for air intake into the spirometer;

[0008] The alcohol detector is equipped with a connecting tube, and an electrochemical sensor for detecting alcohol is installed inside the connecting tube. An extension block connected to the connecting tube is fixed to the side end of the alcohol detector, and a matching groove matching the extension block is opened in the connecting block.

[0009] A connecting component, disposed between the extension block and the connecting block, is used to connect the alcohol detector and the spirometer for use.

[0010] And a compression assembly used in conjunction with the connecting assembly, the compression assembly being used to disconnect the alcohol detector and the spirometer for independent use.

[0011] In one possible design, the connecting assembly includes two second grooves formed within the connecting block, each second groove having a locking block that slides within it, and locking springs fixed to the far ends of the two locking blocks. The two locking springs are respectively fixed within the two second grooves, and the extension block has two locking slots formed within it, with the two locking blocks engaging with the two locking slots respectively.

[0012] In one possible design, the extrusion assembly includes a first groove formed within a connecting block, a sliding plate sliding within the first groove, a pressing plate fixed to the top of the sliding plate, two first springs fixed to the bottom of the sliding plate, the side ends of the two first springs fixed within the first groove, extrusion grooves formed within the two snap-fit ​​blocks, and two extrusion plates fixed to the bottom of the sliding plate, the two extrusion plates moving downwards and penetrating into the two extrusion grooves respectively, the two extrusion plates contacting the inclined surfaces of the two extrusion grooves respectively.

[0013] In one possible design, the side end of the extension block is fixed with a sealing gasket for sealing the extension block and the connecting block.

[0014] In one possible design, a first handle is fixed to the bottom of the alcohol detector, and a second handle is fixed to the bottom of the spirometer, with the bottom ends of the first and second handles at the same horizontal plane.

[0015] In one possible design, both the bottom of the first handle and the second handle are provided with anti-slip pads.

[0016] In this application, during use, one takes a deep breath and then blows air into the inhalation tube. The blown air enters the connecting tube and passes through an electrochemical sensor installed in the connecting tube. Alcohol is converted into acetaldehyde, releasing electrons in the process. These electrons cause a change in the current of the electrochemical sensor. The microprocessor measures the current of the sensor to determine the alcohol content in the exhaled breath and converts it into the blood alcohol content value. Subsequently, the gas passes through the connecting tube, extension block, and connecting block into the spirometer for spirometry testing.

[0017] When the alcohol tester and spirometer need to be separated, press the pressure plate. The pressure plate moves the slide downwards, which in turn moves the compression plate downwards. The compression plate presses against the inclined surface of the compression groove, causing the compression groove to move away from the other side. The compression groove then leaves the locking slot, allowing the alcohol tester and spirometer to be used separately. When they need to be connected, insert the extension block into the matching slot. The elasticity of the locking spring pushes the locking block into the locking slot, fixing the positions of the alcohol tester and spirometer for simultaneous use.

[0018] Beneficial effects

[0019] In this utility model, the lung function and alcohol measuring device can be connected to an alcohol detector and a spirometer by means of a connecting component, so that the user's spirometer can be measured at the same time as the alcohol measurement.

[0020] In this utility model, the lung function and alcohol measuring device can be separated into an alcohol detector and a spirometer through a squeezing component, so that they can be used separately.

[0021] In this invention, the technical solution incorporates an alcohol detector and a spirometer to perform both alcohol and spirometer tests. A connecting assembly allows for rapid connection and integration of the two devices, enabling simultaneous alcohol testing and spirometer testing. The air blown into the alcohol detector is then transferred to the spirometer via a connecting tube for spirometer testing, effectively enhancing the functionality of the alcohol testing equipment and attracting consumer attention.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1

[0031] Reference Figures 1-6 A lung function and alcohol measurement device, used in the field of alcohol measurement technology, includes an alcohol detector 1 and a spirometer 2. The alcohol detector 1 has a blow tube 3 at its top and also includes:

[0032] Connecting block 6, which is fixed to the side of the spirometer 2 for air intake into the spirometer 2;

[0033] The alcohol detector 1 includes a connecting tube 21 containing an electrochemical sensor for detecting alcohol. An extension block 18, connected to the connecting tube 21, is fixed to the side of the alcohol detector 1. A matching groove 19, matching the extension block 18, is provided in the connecting block 6. In use, a deep breath is inhaled, followed by blowing into the air tube 3. The blown air enters the connecting tube 21 and passes through the electrochemical sensor within it. Alcohol is converted to acetaldehyde, releasing electrons in the process. These electrons cause a change in the current of the electrochemical sensor. The microprocessor measures the current of the sensor to determine the alcohol content in the breath and converts it into a blood alcohol content value. The gas then passes through the connecting tube 21, the extension block 18, and the connecting block 6 into the lung capacity detector 2 for lung capacity detection.

[0034] A connecting component is disposed between the extension block 18 and the connecting block 6 for connecting the alcohol detector 1 and the lung capacity detector 2. The connecting component includes two second grooves 12 formed in the connecting block 6, each with a locking block 14 slidingly within it. Locking springs 13 are fixed to the far ends of the two locking blocks 14, and the two locking springs 13 are respectively fixed within the two second grooves 12. Two locking slots 16 are formed in the extension block 18, and the two locking blocks 14 are respectively locked into the two locking slots 16. When connection is required, the extension block 18 is inserted into the matching slot 19, and the elasticity of the locking springs 13 pushes the locking blocks 14 into the locking slots 16, fixing the positions of the alcohol detector 1 and the lung capacity detector 2 for convenient synchronous use.

[0035] And a compression assembly used in conjunction with the connecting assembly, the compression assembly being used to disconnect the alcohol detector 1 and the spirometer 2 for independent use; the compression assembly includes a first groove 8 formed in the connecting block 6, a slide plate 9 sliding in the first groove 8, a pressing plate 7 fixed to the top of the slide plate 9, two first springs 10 fixed to the bottom of the slide plate 9, the side ends of the two first springs 10 being fixed in the first groove 8, compression grooves 15 formed in the two snap-fit ​​blocks 14, and two compression plates 11 fixed to the bottom of the slide plate 9. 1. The two compression plates 11 move downwards and penetrate into the two compression grooves 15 respectively, and the two compression plates 11 contact the inclined surfaces of the two compression grooves 15 respectively. When it is necessary to separate the alcohol detector 1 and the lung capacity detector 2, press the pressing plate 7. The pressing plate 7 drives the sliding plate 9 to move downwards. The sliding plate 9 drives the compression plate 11 to move downwards. The compression plate 11 squeezes the inclined surface of the compression groove 15. The compression groove 15 is squeezed and moves in a direction away from each other. The compression groove 15 leaves the snap-fit ​​groove 16, and the alcohol detector 1 and the lung capacity detector 2 can be separated for use.

[0036] Furthermore, a sealing gasket 20 for sealing the extension block 18 and the connecting block 6 is fixed to the side end of the extension block 18.

[0037] Example 2

[0038] refer to Figures 1-6 An improvement on embodiment 1: A measuring device further includes a first handle 4 fixed to the bottom of the alcohol detector 1, and a second handle 5 fixed to the bottom of the spirometer 2. The bottoms of the first handle 4 and the second handle 5 are on the same horizontal plane; providing two different gripping methods, which can be gripped according to needs;

[0039] The first handle 4 and the second handle 5 are fixed to the bottom of the alcohol detector 1 and the lung capacity detector 2, respectively. After separation, the alcohol detector 1 and the lung capacity detector 2 can be easily taken out.

[0040] The bottom of both the first handle 4 and the second handle 5 are equipped with anti-slip pads; these can be used to support the assembled alcohol detector 1 and spirometer 2.

[0041] However, as is well known to those skilled in the art, the working principles and wiring methods of the alcohol detector 1 and the spirometer 2 are commonplace and are conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0042] Working principle: When using, take a deep breath and then blow air into the air inhalation tube 3. The blown air enters the connecting tube 21. The gas passes through the electrochemical sensor installed in the connecting tube 21, where alcohol is converted into acetaldehyde. During this process, electrons are released, causing a change in the current of the electrochemical sensor. The microprocessor measures the current of the sensor to measure the alcohol content in the exhaled breath and converts it into the blood alcohol content value. Subsequently, the gas passes through the connecting tube 21, the extension block 18, and the connecting block 6 into the lung capacity detector 2 to detect lung capacity.

[0043] When it is necessary to separate the alcohol detector 1 and the lung capacity detector 2, press the press plate 7. The press plate 7 moves the slide plate 9 downward, and the slide plate 9 moves the squeeze plate 11 downward. The squeeze plate 11 squeezes the inclined surface of the squeeze groove 15. The squeeze groove 15 is squeezed and moves in the opposite direction. The squeeze groove 15 leaves the snap-fit ​​groove 16, so the alcohol detector 1 and the lung capacity detector 2 can be separated for use. When it is necessary to connect them, insert the extension block 18 into the matching groove 19. The snap-fit ​​spring 13 pushes the snap-fit ​​block 14 to snap into the snap-fit ​​groove 16, fixing the position of the alcohol detector 1 and the lung capacity detector 2 for convenient synchronous use.

[0044] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
