Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an air allergen sampling device. Background Art

[0002] Airborne allergenic pollen is an important outdoor allergen with a diameter of about 10 to 100 microns. It can induce a variety of allergic diseases such as allergic rhinitis, allergic conjunctivitis, allergic asthma, and allergic dermatitis. The onset of allergic diseases induced by pollen is highly consistent with the peak pollen season. The severity of pollen allergy symptoms depends on the amount of pollen and the duration of contact. Seasonal allergic rhinitis caused by tree pollen in spring and weed pollen in autumn is very serious.

[0003] Pollen allergy not only directly damages the physiological functions of patients, but also seriously affects the quality of life, causing a series of problems such as low learning and work efficiency, missed work, increased economic burden, and then causing psychological problems such as anxiety and depression, which seriously endangers human health. Pollen monitoring is currently internationally recognized as the most reliable and feasible method to assess the health hazards of pollen allergy patients.

[0004] At present, in terms of pollen collection, the mainstream practice is still to place a clean glass slide on a special collection device and choose a location with strong air flow to arrange it so that the pollen in the air can naturally settle on its surface. However, this process requires a dedicated person to regularly replace the glass slides on site, such as daily, every two days or once a week. Obviously, this traditional method that relies on manual labor not only consumes a lot of human resources, but also cannot accurately control the specific time point of each replacement, which easily causes timing deviations between samples, thereby affecting the accuracy and reliability of the final analysis results. Therefore, it is urgent to develop an air allergen sampling device to solve the above technical problems efficiently and ensure data consistency. Summary of the invention

[0005] The purpose of the present invention is to provide an air allergen sampling device to solve the technical problem that in the prior art, a dedicated person cannot accurately control the specific time point of each replacement when replacing the glass slide on site, which easily causes a timing deviation between samples, thereby affecting the accuracy and reliability of the final analysis result.

DETAILED DESCRIPTION

[0027] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The following is combined with Figure 1-7 The present application is further described in detail. An embodiment of the present application discloses an air allergen sampling device.

[0031] Reference Figure 1 and Figure 2 As shown, an air allergen sampling device includes: a box 100, a rotating mechanism 300, an adhesive coating mechanism 200 and a driving mechanism 400. An inner cavity with an opening at the top is provided inside the box 100 for accommodating the main components. A cover plate 120 that can be opened and closed is installed on the top of the box 100. When the cover plate 120 is closed, it can tightly cover the opening of the inner cavity to prevent external interference. A collection port 160 for air samples to enter is provided on the top surface of the cover plate 120. A flip cover port 130 is provided on the side of the cover plate 120 opposite to the collection port 160. A flip cover 140 is hinged at the flip cover port 130. By flipping the flip cover 140, a small device can be directly installed on the rotating mechanism 300 without opening the cover plate 120.

[0032] Reference Figure 3 and Figure 4 As shown, the rotating mechanism 300 is disposed inside the housing 100, and a rotating disk 180 is mounted on the rotating mechanism 300. The rotating disk 180 is arranged to rotate horizontally, and a plurality of collecting boxes 500 are mounted on the rotating disk 180 and are arranged to slide along the radial direction of the rotating disk 180. The plurality of collecting boxes 500 are arranged along the circumferential direction of the rotating disk 180. Through the rotational movement of the rotating mechanism 300, each collecting box 500 can sequentially reach the predetermined collecting port 160 for air allergen sampling.

[0033] Reference Figure 4 and Figure 5 As shown, the adhesive coating mechanism 200 is fixedly mounted on the cover plate 120 and corresponds to the position of the collection port 160. When the glass slide needs to be exposed to the outside through the collection port 160, the adhesive coating mechanism 200 immediately coats the glass slide with adhesive to ensure that the adhesive remains moist during use, effectively avoiding the drying of the adhesive due to the early application of the adhesive, and the falling of the adhesive on the air sample before the collection time, thereby ensuring the quality of air allergen sampling.

[0034] The driving mechanism 400 is also fixed on the cover plate 120 and is responsible for pushing the collection box 500 to move horizontally along the radial direction of the turntable 180. When air allergen sampling is required, the driving mechanism 400 will push the designated collection box 500 under the collection port 160 to receive the air sample entering from the collection port 160.

[0035] The controller 110 is connected to the rotating mechanism 300, the adhesive coating mechanism 200 and the driving mechanism 400 respectively through electrical signals. The controller 110 can accurately control the actions of the above mechanisms according to a preset program or external instructions, including the rotation angle of the turntable 180, the adhesive coating timing, and the in and out speed of the collection box 500, thereby realizing an automated air allergen sampling process, further improving the intelligence level and operation convenience of the device.

[0036] The rotating mechanism 300 is used to achieve precise rotation control, and includes a servo motor 310, a base 320 and a swivel 330. The base 320 is fixedly connected to the top and bottom of the box 100 to serve as the basic support of the entire rotating mechanism 300 and ensure the stability of the rotating mechanism 300 during operation. Secondly, the swivel 330 passes through the inner cavity opening of the box 100 from the center line of the base 320, one end of which extends outward from the top of the box 100, and the other end is arranged inside the box 100 and is provided with a gear. The servo motor 310 is fixedly mounted on the base 320, and its driving end is meshed with each other through the gear on the swivel 330, so as to realize the transmission of the driving torque output by the motor to the swivel 330. The swivel 330 is arranged at the outer end of the box 100 and is coaxially fixedly connected with the turntable 180, so that when the swivel 330 rotates, it can directly drive the turntable 180 to rotate synchronously, ensuring the consistency of movement between the two.

[0037] In addition, the servo motor 310 and the controller 110 are electrically connected to each other, and the controller 110 precisely controls the rotation angle and speed of the servo motor 310, thereby precisely regulating the position change of the turntable 180. This precise control not only improves the response speed and positioning accuracy of the system, but also improves the working efficiency and reliability of the entire device.

[0038] Eight slide grooves 190 are evenly distributed on the turntable 180. These slide grooves 190 extend along the radial direction of the turntable 180, that is, they are arranged radially from the center to the outside. Two parallel slide rails 191 are provided on the side wall of each slide groove 190. These two slide rails 191 fit tightly together to provide a stable support and guide for the collection box 500 placed thereon.

[0039] Reference Figure 6 and Figure 7 As shown, the collection box 500 includes a box bottom 510 for accommodating glass slides and a box cover 520 for covering the box bottom 510 and sealing the glass slides to protect the glass slides inside from contamination or damage. The box bottom 510 has track grooves 511 arranged corresponding to the slide rails 191 on both sides. When installing the collection box 500, it is only necessary to align the box bottom 510 with the slide groove 190, align and insert the two slide rails 191 in the slide groove 190 with the track grooves 511 on the box bottom 510, and the collection box 500 can be easily and stably slid in the slide groove 190. This ensures that the collection box 500 can slide smoothly in the slide groove 190 without tilting or shaking.

[0040] The sliding direction of the collection box 500 is the length direction of the collection box 500, which helps to ensure that the glass slide can slide smoothly in the slide groove 190 on the turntable 180 together with the collection box 500. The bottom 510 of the box is provided with a receiving groove 512 with an opening at the top. The size and shape of the receiving groove 512 are specially used to receive the glass slide, and the width ends of the glass slide will be close to the two side walls of the receiving groove 512, thereby providing necessary stability during installation and use, preventing the glass slide from shifting or falling off, and especially avoiding the risk of glass slide loss or damage in windy weather in traditional collection devices.

[0041] A certain gap is left between the side wall in the length direction of the glass slide and the receiving groove 512, mainly to facilitate the user to easily remove or replace the glass slide when needed, thereby ensuring the simplicity of operation and not affecting the firmness of the glass slide during use.

[0042] The edges of both sides of the length of the bottom 510 are respectively provided with dovetail grooves 530 with the openings facing upwards, and the two dovetail grooves 530 run through the entire length of the bottom 510. Correspondingly, two dovetail strips 540 matching the dovetail grooves 530 are provided on the side of the box cover 520 facing the bottom 510, and are fixedly connected to the bottom of the box cover 520. During the installation process, the box bottom 510 can be pushed along the width direction of the box bottom 510 so that the dovetail strips 540 are aligned with the dovetail grooves 530 and inserted smoothly, thereby achieving a tight connection between the box cover 520 and the bottom 510, forming a completely sealed state. This method is not only simple and easy to implement, but also effectively avoids the possibility of external pollutants entering the interior of the collection box 500, ensuring the safety and cleanliness of the internal slides.

[0043] In the width direction of the box cover 520, there is a step block 550 protruding upwards. The step block 550 is higher than the bottom surface of the box cover 520 and gradually protrudes outward near the center of the box cover 520. A corresponding step groove 560 is also provided in the width direction of one side of the box bottom 510. The step groove 560 is formed by the outer surface of the box bottom 510 being recessed inwards. When the collection box 500 is correctly installed on the turntable 180, one end with the step groove 560 and the step block 550 should point to the center of the turntable 180, that is, this end is closer to the center of the turntable 180 than the other end of the collection box 500.

[0044] When the collection box 500 needs to be opened for maintenance or replacement of the slide, the box bottom 510 is pushed by the driving device to move along the slide rail 191 in a direction away from the center of the turntable 180. During this process, the step block 550 will separate from the step groove 560, especially the part close to the center of the box cover 520 will be out of contact first, thus avoiding possible interference between the step block 550 and the step groove 560 during the sliding process, ensuring that the box bottom 510 can slide out smoothly, which is convenient for the user to perform subsequent operations.

[0045] A first tilting block 570 and a second tilting block 580 are also provided in the width direction of the collection box 500. The first tilting block 570 is fixedly connected to the width end surface of the box bottom 510, located on the side opposite to the stepped groove 560, and its tilting angle gradually increases from one end close to the receiving groove 512 to the other end. The second tilting block 580 is fixed to the bottom surface of the box cover 520, and its tilting angle gradually decreases from one end close to the center of the box cover 520 to the end of the box cover 520. When the box cover 520 and the box bottom 510 are closed, the inclined surfaces 150 of the first tilting block 570 and the second tilting block 580 will fit closely together.

[0046] In this way, the path for particles in the air to enter the collection box 500 from the side wall in the length direction of the collection box 500 is increased through the cooperation between the dovetail groove 530 and the dovetail bar 540, the step groove 560 and the step block 550, and the first inclined block 570 and the second inclined block 580, thereby effectively preventing foreign matter from entering the interior of the collection box 500 and ensuring that the slide inside the collection box 500 is clean and tidy.

[0047] An inclined surface 150 is provided at one end of the cover plate 120, and the inclined surface 150 is lower than the top surface of the cover plate 120 on the side facing the west of the cover plate 120, that is, the inclined surface 150 is gradually inclined and lowered from the side close to the cover plate 120 to the edge end of the cover plate 120. The collection port 160 is opened at the inclined surface 150 and is perpendicular to the inclined surface 150 and penetrates through it.

[0048] When collecting air samples, the turntable 180 rotates driven by the servo motor 310, and drives the collection box 500 on the turntable 180 to be located below the collection port 160, and closer to the center of the turntable 180 in the radial direction of the turntable 180. At this time, the driving mechanism 400 pushes the box bottom 510 carrying the slide to slide out along the slide rail 191 and is pushed out from the collection port 160 to collect the side wall of the air sample.

[0049] By arranging the collection port 160 at the inclined surface 150, the influence of the cover plate 120 on the glass slide during air sample collection can be reduced, making the operation smoother. By pushing the box bottom 510 on which the glass slide is placed out of the collection port 160, the obstruction that the cover plate 120 may cause during the glass slide collection process is reduced, so as to collect air samples.

[0050] The driving mechanism 400 includes an electromagnetic slide bar 410 and an electromagnetic slider 420. The electromagnetic slide bar 410 is fixedly connected to the inner side of the inclined surface 150 of the cover plate 120, and the length extension direction of the electromagnetic slide bar 410 is extended along the radial direction of the turntable 180, and the length extension direction of the electromagnetic slide bar 410 and the collecting port 160 are in the same radial direction of the turntable 180, and the electromagnetic slider 420 is slidably arranged along the length direction of the electromagnetic slide bar 410. A connecting component for connecting the collecting box 500 is arranged on the electromagnetic slider 420. The electromagnetic slide bar 410 is electrically connected to the controller 110, so that the controller 110 controls the electromagnetic slider 420 on the electromagnetic slide bar 410 to move along the electromagnetic slide bar 410.

[0051] The connection assembly includes a connection rod 430 and a magnetic plate 440. One end of the connection rod 430 is fixedly connected to the electromagnetic slider 420, and the other end is fixedly connected to the magnetic plate 440. The length extension direction of the connection rod 430 is perpendicular to the length extension direction of the electromagnetic slider 410. An iron sheet is provided on the side wall of the bottom of each collection box 500 facing the center of the turntable 180, so that the magnetic plate 440 can absorb and push the box bottom 510 to move, ensuring accuracy and reliability during operation.

[0052] When air sample collection is required, the servo motor 310 drives the turntable 180 to rotate so that the designated collection box 500 moves to the bottom of the collection port 160, and the servo motor 310 stops running. This precise positioning technology ensures that each collection can be carried out at the correct position, improving the efficiency and success rate of sample collection. Subsequently, under the instruction of the controller 110, the electromagnetic slider 420 drives the connecting rod 430 and the magnetic plate 440 installed thereon to approach the bottom of the collection box 500. When the magnetic plate 440 contacts the bottom of the box 510, it will form a magnetic fixation with the iron sheet on the bottom of the box 510. Then, the electromagnetic slider 420 continues to slide along the electromagnetic slide rod 410, and pushes the bottom of the box 510 to move outward along the slide rail 191, thereby realizing the action of pushing the slide out of the collection port 160.

[0053] When the box bottom 510 needs to be reset, the electromagnetic slider 420 moves along the electromagnetic slide rod 410 toward the center of the turntable 180, and the magnetic attraction between the magnetic plate 440 and the iron sheet is used to pull the box bottom 510 toward the center of the turntable 180 to complete the reset operation.

[0054] When the bottom 510 of the box is reset, the electromagnetic slider 420 continues to move toward the center of the turntable 180, and the magnetic plate 440 overcomes the magnetic attraction between the magnetic plate and the iron sheet, and finally separates from the collection box 500 that has completed the air allergen sampling. This separation process ensures that the next sample collection step can start smoothly, further optimizing the overall operation process.

[0055] After separation is completed, the electromagnetic slider 420 stops sliding, and the servo motor 310 starts again, driving the turntable 180 to rotate to replace the next collection box 500. After replacement, the electromagnetic slider 420 repeats the above-mentioned pushing and resetting actions to collect the air sample of the next slide. Through the coordinated operation of the servo motor 310 and the electromagnetic slider 420, fast and accurate sample collection and replacement are achieved, which significantly improves the working efficiency and reliability of the equipment.

[0056] By presetting the time interval for replacing the slide in the controller 110, the rotation and timing of the servo motor 310, and the subsequent push-out and reset actions of the electromagnetic slider 420 can be accurately controlled. This time control mechanism enables the device to continue to operate efficiently without the need for professionals to replace the slide, further enhancing its practicality and automation.

[0057] The adhesive coating mechanism 200 includes an adhesive storage box 210, a roller 250, and a sponge strip 270. The cover plate 120 is provided with a through hole 170 for placing the adhesive storage box 210, the adhesive storage box 210 is inserted into the through hole 170, and the adhesive storage box 210 can be adjusted in height on the cover plate 120 along the through hole 170, and the cover plate 120 is provided with an adjustment component for adjusting the height of the adhesive storage box 210. Specifically, the adhesive storage box 210 and the collection port 160 are located in the same radial direction of the turntable 180, and the position of the adhesive storage box 210 is closer to the center of the turntable 180 than the collection port 160, and the adhesive storage box 210 is arranged adjacent to the collection port.

[0058] The adhesive storage box 210 has an adhesive containing cavity 211 with a positioning opening, and the bottom surface of the adhesive storage box 210 also has an adhesive sinking cavity 212 that penetrates through it. The adhesive sinking cavity 212 is connected to the adhesive containing cavity 211 and is located on the bottom surface of the adhesive containing cavity 211. The roller 250 is rotatably arranged in the adhesive sinking cavity 212, and the roller 250 protrudes from the bottom surface of the adhesive box 210 and is arranged in the adhesive storage box 210. The adhesive sinking cavity 212 has adhesive cotton 240 and a screen 230. The adhesive cotton 240 is laid in the adhesive containing cavity 211 and contacts the roller 250, and the screen 230 is laid on the adhesive cotton 240.

[0059] Considering that long-term exposure of the adhesive may cause chemical changes due to environmental factors (such as temperature, humidity, etc.), resulting in reduced viscosity and affecting the pollen adhesion effect; at the same time, too long exposure time may also cause the adhesive to absorb dust, microorganisms and other impurities in the air, interfering with the results of pollen collection and analysis. For this reason, in this application: when it is necessary to collect air samples from the slide or replace a new slide, the slide will pass through the adhesive storage box 210 and the collection port 160 in turn to achieve the purpose of instant application of the adhesive. The specific operation steps are as follows:

[0060] Driven by the collection box 500, the glass slide first passes through the adhesive storage box 210. At this time, the surface of the glass slide will contact the adhesive pre-placed in the adhesive storage box 210, and a layer of fresh adhesive will be evenly applied through the action of the roller 250 to ensure the freshness of the adhesive and its good adhesion performance; then, the glass slide continues to move and reaches the location of the collection port 160, and starts to perform the normal air sample collection task. In this way, the glass slide just completes the adhesive coating process before entering the collection port 160, which enhances the adhesion ability of its surface, so that it can more effectively capture and fix pollen particles in the air, avoid pollen loss caused by external conditions (such as wind speed changes), and improve collection efficiency and quality.

[0061] The setting of the screen 230 ensures that the adhesive can be uniformly infiltrated into the adhesive-infiltrated cotton 240. By laying the adhesive-infiltrated cotton 240 in the adhesive-infiltrated cavity, the adhesive is blocked to prevent excessive flow and dripping of the adhesive. And by utilizing the contact between the adhesive-infiltrated cotton 240 and the roller 250, the infiltrated adhesive is smeared on the roller 250 as the roller 250 and the adhesive-infiltrated cotton 240 roll in contact, so that the adhesive is rolled and laid on the surface of the slide when it contacts the slide.

[0062] The adhesive coating mechanism 200 also includes a sponge bar 270, which is fixedly connected to the bottom surface of the adhesive storage box 210, and the sponge bar 270 is arranged closer to the center of the turntable 180 relative to the roller 250, that is, the glass slide preferentially contacts the sponge bar 270 during the process of being pushed out to coat the adhesive, so that the sponge bar 270 can wipe and clean the surface of the glass slide.

[0063] The adhesive coating mechanism 200 further includes at least one scraper 260, which is also fixedly connected to the bottom surface of the adhesive storage box 210 and the positions where the scraper 260 and the sponge strip 270 are set are symmetrically arranged with the roller 250 as the center. The plurality of scrapers 260 are evenly arranged along the length direction of the adhesive storage box 210, i.e., the moving direction of the paddle. The scraper 260 is provided with a V-shaped cutout 261 facing the side of the roller 250, and the opening direction of the V-shaped cutout 261 is arranged toward the direction of the roller 250, and the opening direction of the V-shaped cutout 261 is arranged along the length direction of the scraper 260.

[0064] After the roller 250 applies adhesive to the surface of the glass slide, the glass slide will contact the scraper 260 as it continues to move, and the scraper 260 will scrape the adhesive on the glass slide. The multiple scraping actions of the multiple scrapers 260 can ensure that the adhesive on the surface of the glass slide is smooth and even after passing through the adhesive coating mechanism 200, and in this process, excess adhesive will be collected at the V-shaped cutout 261, and supplemented to the position on the glass slide with less adhesive in the subsequent scraping process.

[0065] The adhesive coating mechanism 200 further includes a sealing cover 220 and a heating plate, wherein the sealing cover 220 is used to seal the top opening of the adhesive storage box 210 to prevent the adhesive inside the adhesive box 210 from solidifying. The heating plate is fixedly mounted on the inner wall of the adhesive storage box 210, and the heating plate is electrically connected to the controller 110. The adhesive in the adhesive storage box 210 is heated in a timely manner before each rotation of the turntable 180 through the control of the controller 110, so as to ensure that the adhesive storage box 210 is at a constant temperature or a set temperature, and to ensure the fluidity of the adhesive in the adhesive storage box 210.

[0066] The adhesive coating mechanism 200 further includes a limiter 610 for limiting the movement of the box cover 520 when the box cover 520 is separated from the box bottom 510 . Thus, when the electromagnetic slider 420 pushes the box bottom 510 to move, the limiter limits the movement of the box cover 520 to facilitate the separation of the box cover 520 from the box bottom 510 .

[0067] The limiting member 610 is a limiting block fixedly mounted on the adhesive storage box 210, and the limiting block is provided with a limiting groove 620 in the direction of the center of the rotating disk 180. The box cover 520 is fixedly connected with a positioning block 590, and the positioning block 590 is arranged at the position where the second tilting block 580 is mounted on the box cover 520. In this way, the positioning block 590 can rotate and slide through the limiting groove 620 during the rotation of the rotating disk 180. When the air sample is collected, the positioning block 590 on the box cover 520 of the collection box 500 with the slide placed thereon is just located in the limiting groove 620. At this time, when the box bottom 510 is pushed to slide, the box cover 520 is limited by the positioning block 590 to complete the relative sliding separation of the box cover 520 and the box bottom 510.

[0068] The adjustment component includes an electric slide rod 280 fixedly connected to the bottom surface of the cover 120, and the length extension direction of the electric slide rod 280 is perpendicular to the plane of the cover 120. An electric slider 290 is slidably arranged on the electric slide rod 280. The electric slider 290 is fixedly connected to the adhesive storage box 210, so that the electric slider 290 can carry the adhesive storage box 210 to move in the height direction, and the limit groove 620 is provided with a movable space for the positioning block 590 during the sliding process of the limit block.

[0069] The electric slider 290 is electrically connected to the controller 110. When the positioning block 590 is stuck in the limiting groove 620, there is a certain distance between the positioning block 590 and the bottom surface of the limiting groove 620. At this time, when the box bottom 510 is pushed to slide out toward the collection port 160, the positioning block 590 of the box cover 520 abuts against the side wall of the limiting groove 620. When the box bottom 510 is completely detached, the positioning block 590 falls down and contacts the bottom surface of the limiting groove 620 under the weight of the box cover 520. When the box bottom 510 retracts and resets, the controller 110 controls the electric slider 290 to move and drive the adhesive storage box 210 to move upward, and the moving distance is equal to the falling distance of the positioning block 590, so as to ensure that the dovetail strip 540 is aligned with the dovetail groove 530 and inserted, and at the same time, the roller 250 is prevented from applying adhesive to the slide glass for the second time.

[0070] This enables automatic replacement and adhesive application of the slide without human intervention.

Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
