Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an intelligent grasping device and method for a breath sampler mouthpiece. Background Technology

[0002] The composition and level of volatile organic compounds (VOCs) in human exhaled breath can reflect the body's metabolic status and have been widely used in the past two decades for auxiliary diagnostic research on various lung diseases, such as lung cancer, asthma, and cystic fibrosis. In recent years, several domestic and international patents have been obtained. The work of identifying specific VOC components in the exhaled breath of patients with chronic obstructive pulmonary disease (COPD) in China to aid in disease diagnosis is receiving increasing attention.

[0003] Existing patents, such as CN109009236A, disclose a human exhaled gas collection device and method. This device has a mouthpiece connected to the front end of a collection tube wrapped in an insulated sleeve. Near the front end, there is an air inlet bypass connecting to a synthetic air container. Synthetic air is introduced into the collection tube after passing through an activated carbon filter and a gas flow controller. Near the end of the collection tube, there is a pressure regulating bypass. The end of the collection tube is connected to a detection instrument or a gas storage bag via a pipe. This invention uses a wet, non-invasive collection method, ensuring the non-coercive nature of the subject during sampling and a high consistency between the collected gas and the actual exhaled gas, avoiding interference from external air. Compared to the mask-based compression collection method, it is lower in cost, more acceptable to subjects, and suitable for large-scale sampling. However, in actual use, a mouthpiece needs to be manually connected, which is inconvenient and can lead to bacterial contamination, increasing the overall collection time and reducing the applicability of the exhaled gas collection device. Furthermore, the technology has a low degree of automation and cannot demonstrate intelligent collection capabilities. Therefore, we propose an intelligent mouthpiece grasping device and method for an exhaled gas collector. Summary of the Invention

After payment, the breath sampler will automatically start working normally.

[0016] B: The first rotating mechanism is used to rotate the gripping arm assembly, so that it rotates 180 degrees in the XY plane, so that the gripping mechanism is aligned with the mouthpiece fixed at the top of the arrangement assembly. Then, the gripping mechanism is driven to make a slight downward adjustment through the Z-axis moving mechanism, so that the gripping mechanism can grasp the mouthpiece.

[0017] C: After grabbing the mouthpiece, the Z-axis moving mechanism drives the grabbing mechanism to make a slight upward adjustment to return to the initial position, and then the first rotating mechanism is started to rotate the grabbing arm mechanism to return it to the initial position;

[0019] E: Then, the second rotating mechanism rotates the horizontal plate ninety degrees so that the mouthpiece tube is aligned with the connecting tube at the top of the exhalation collector. Then, the Z-axis moving mechanism moves downward so that the mouthpiece slowly approaches the exhalation collector, thereby connecting the mouthpiece with the connecting tube of the exhalation collector.

[0020] F: After docking, the Z-axis moving mechanism returns to its initial position, and the push component moves the exhalation collector forward. At this time, the user can blow into the mouthpiece. The exhalation collector records and analyzes the composition of the user's exhaled gas. After 30 seconds, the gas composition report is displayed on the terminal of the exhalation collector.

[0021] G: Then, the Z-axis moving mechanism moves downward to allow the gripping mechanism to grip the nozzle. The Z-axis moving mechanism moves upward to pull out the nozzle. Then, the first rotating mechanism rotates the gripping mechanism. When it rotates to the top of the trash can, the gripping mechanism is released, and the discarded nozzle automatically falls into the trash can.

[0022] H: The first rotating mechanism reverses the gripping mechanism based on step G, so that the gripping mechanism returns to its initial position. When the next user uses it, the turntable rotates at a certain angle to replace the mouthpiece in the previous position, and then the above steps are repeated to collect exhaled breaths.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This invention, through the coordinated design of the arrangement components, gripping arm components, adjustment components, pushing components, trash can, and sensing system, eliminates the need for users to touch and manually install the mouthpiece during use.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figure 1 , Figure 2 and Figure 10As shown in the figure, an intelligent grasping device and its grasping method for a breath sampler mouthpiece are included. The device includes a mounting housing 1, a mounting plate 2 fixed to one side of the housing 1, a breath sampler 3 mounted on the mounting plate 2, and an auxiliary collection component 4 for automatically installing and removing the mouthpiece mounted on the housing 1. The auxiliary collection component 4 includes an arranging component 5, a grasping arm component 6, an adjusting component 7, and a pushing component 8. The arranging component 5 is installed inside the housing 1. The grasping arm component 6 and the adjusting component 7 are both located above the top of the mounting plate 2. The output end of the adjusting component 7 is connected to the grasping arm component 8. The arm assembly 6 is connected by a drive mechanism, and the push assembly 8 is installed at the bottom of the breath sampler 3. A trash can 9 is fixed to the rear side of the mounting housing 1, and a sensing system 10 is installed on the side of the mounting housing 1. Through the coordinated design of the arrangement assembly 5, the gripping arm assembly 6, the adjustment assembly 7, the push assembly 8, the trash can 9, and the sensing system 10, the user does not need to touch or manually install the mouthpiece during use, which improves sampling efficiency, reduces bacterial contact, and expands the applicability of the breath sampling device. In addition, it also improves the degree of automation during breath sampling, demonstrating the effect of intelligent sampling.

[0039] Among them, such as Figure 3 As shown, to facilitate the replacement of mouthpieces, the arrangement assembly 5 includes a turntable 11, a drive shaft 12, a first motor 13, a drive pulley 14, and a driven pulley 15. The turntable 11 is rotatably connected to the inside of the mounting housing 1 via the drive shaft 12. The first motor 13 is fixed to the inner wall of the mounting housing 1, and its output end is fixedly connected to the drive pulley 14. The driven pulley 15 is fixed to the outside of the drive shaft 12 and is connected to the drive pulley 14 via a synchronous belt. Multiple fixing components 16 for adsorbing and clamping mouthpieces are evenly installed on the outside of the turntable 11. The arrangement assembly 5 enables the adjustment of the position of multiple fixing components 16, thereby facilitating the movement and replacement of multiple mouthpieces and making it convenient to remove the mouthpieces.

[0040] At the same time, such as Figure 4As shown, in order to clamp the mouthpiece, the fixing assembly 16 includes a first fixing plate 17, an arc-shaped support plate 18, a first support plate 19, a straightening cylinder 20, and a clamping plate 21. The first fixing plate 17 is fixed to the outside of the turntable 11. Two first support plates 19 are provided, and the two first support plates 19 are symmetrically fixed to the top sides of the first fixing plate 17. The arc-shaped support plate 18 is fixed between the two first support plates 19. The straightening cylinder 20 is fixed on the first support plate 19. The clamping plate 21 is fixed to the output end of the straightening cylinder 20. A vacuum pump 55 is installed on the first fixing plate 17. The output end of the vacuum pump 55 is connected to an air guide pipe 56. Multiple negative pressure suction pipes 57 are connected to the air guide pipe 56. Multiple suction holes 58 are opened inside the arc-shaped support plate 18 to be inserted into the negative pressure suction pipes 57. A conveyor belt device 59 is also installed at the bottom inside the mounting housing 1. New mouthpieces can be replenished in time through the conveyor belt device 59 to facilitate continuous use of the equipment.

[0041] When continuously supplying the nozzles: First, the conveyor belt device 59 will transport the nozzles placed on it. When it is transported to the area directly below the arc-shaped support plate 18, the vacuum pump 55 will be activated. The vacuum pump 55 will generate a vacuum at the opening of the suction hole 58 and create a pressure difference with the area above the nozzle, thereby sucking the nozzle into the arc-shaped support plate 18. After it is sucked in, the two straightening cylinders 20 will be activated. The straightening cylinders 20 will drive the two clamping plates 21 to center and clamp the nozzle, thereby fixing the nozzle on the arrangement assembly 5. The subsequent nozzle supply method is the same as above.

[0042] In addition, such as Figure 5 As shown, in order to achieve the gripping of the mouthpiece and docking of the mouthpiece with the exhalation collector, the gripping arm assembly 6 includes a horizontal plate 22, an X-axis moving mechanism 23, and a gripping mechanism 24. A limit groove is provided on the horizontal plate 22. The X-axis moving mechanism 23 includes a limit connecting post 25, a moving block 26, a first lead screw 27, and a second motor 28. The limit connecting post 25 is slidably connected in the limit groove. The moving block 26 is fixed to the top of the limit connecting post 25. The first lead screw 27 is threadedly connected to the moving block 26. Both sides of the first lead screw 27 are connected to the top of the horizontal plate 22 through bearing seats. The output end of the second motor 28 is fixedly connected to the first lead screw 27 through a coupling, and the tail end of the second motor 28 is fixedly connected to the end of the horizontal plate 22 away from the mounting housing 1 through a connecting plate. The gripping mechanism 24 is fixed to the bottom end of the limit connecting post 25.

[0043] At the same time, such as Figure 7 and Figure 8As shown, in order to adjust the position of the gripping arm assembly 6, the adjustment assembly 7 includes a first rotating mechanism 36, a Z-axis moving mechanism 37, and a second rotating mechanism 38. The first rotating mechanism 36 includes a fourth motor 39, a first gear 40, a second gear 41, and a support cylinder 42. The tail end of the fourth motor 39 is fixedly connected to the mounting plate 2 through a connecting plate. The first gear 40 is fixed to the output end of the fourth motor 39. The support cylinder 42 is fixed on the mounting plate 2 and is rotatably connected to the second gear 41 through a bearing. The second gear 41 meshes with the first gear 40. The Z-axis moving mechanism 37 is mounted on the second gear 41.

[0044] In addition, such as Figure 8 As shown, in order to adjust the gripping arm assembly 6 in the Z-axis direction, the Z-axis moving mechanism 37 includes a fifth motor 43, a third lead screw 44, and an adjusting block 45. The fifth motor 43 is fixed inside the second gear 41. The third lead screw 44 is fixedly connected to the output end of the fifth motor 43 through a coupling. The adjusting block 45 is threadedly connected to the third lead screw 44. A second slide rod 46 is provided on one side of the third lead screw 44. The bottom end of the second slide rod 46 is fixed to the top end of the second gear 41, and the adjusting block 45 is slidably connected to the outside of the second slide rod 46. The second rotating mechanism 38 is fixed to one end of the adjusting block 45 and is connected to one end of the horizontal plate 22.

[0045] At the same time, such as Figure 8 As shown, in order to achieve the rotation of the gripping arm assembly 6, the second rotating mechanism 38 includes a sixth motor 47, a third gear 48 and a fourth gear 49. The sixth motor 47 is fixed on the outside of the adjusting block 45, the third gear 48 is fixed on the output end of the sixth motor 47, the fourth gear 49 is meshed with the third gear 48, one end of the central shaft of the fourth gear 49 is fixedly connected to the horizontal plate 22, and the other end is rotatably connected to the adjusting block 45 through a bearing.

[0046] like Figures 1-10 As shown, a method for grasping an intelligent grasping device for a breath sampler mouthpiece includes the following steps:

[0047] A: First, after sensing and identifying through the sensing system 10, or after scanning the code with a mobile phone, the audio and video display will guide you on how to use the device (it can ask if you need guidance, or tell you if you are a new or old customer, and know if the customer has an APP on their mobile phone). After payment, the breath sampler 3 will automatically start working normally.

[0048] B: The first rotating mechanism 36 is used to rotate the gripping arm assembly 6 so that it rotates 180 degrees in the XY plane, so that the gripping mechanism 24 is aligned with the mouthpiece fixed at the top of the arrangement assembly 5. Then, the gripping mechanism 24 is driven to make a slight downward adjustment through the Z-axis moving mechanism 37 so that the gripping mechanism 24 grips the mouthpiece.

[0049] C: After grabbing the mouthpiece, the Z-axis moving mechanism 37 drives the grabbing mechanism 24 to make a slight upward adjustment to return to the initial position, and then the first rotating mechanism 36 is started to rotate the grabbing arm mechanism to return it to the initial position.

[0050] D: Adjust the gripping mechanism 24 again by using the X-direction moving mechanism 23 on the horizontal plate 22 to move it laterally, so that the mouthpiece gripped by the gripping mechanism 24 is aligned with the connecting tube at the top of the exhalation collector 3.

[0051] E: Then, the second rotating mechanism 38 rotates the horizontal plate 22, causing the horizontal plate 22 to rotate 90 degrees, so that the mouthpiece tube is aligned with the connecting tube at the top of the exhalation collector 3. Then, the Z-axis moving mechanism 37 moves downward to make the mouthpiece slowly approach the exhalation collector 3, so that the mouthpiece and the connecting tube of the exhalation collector 3 are connected.

[0052] F: After docking, the Z-axis moving mechanism 37 returns to the initial position, and the pushing component 8 pushes the exhalation collector 3 forward. At this time, the user can blow into the mouthpiece. The exhalation collector 3 records and analyzes the composition of the user's exhaled gas. After waiting for 30 seconds, the gas composition report is displayed through the terminal of the exhalation collector 3.

[0053] G: Then, the Z-axis moving mechanism 37 moves downward to make the gripping mechanism 24 grip the nozzle. The Z-axis moving mechanism 37 moves upward to pull out the nozzle. Then, the gripping mechanism 24 is rotated by the first rotating mechanism 36. When it is rotated to the top of the trash can 9, the gripping mechanism 24 is released and the discarded nozzle automatically falls into the trash can 9.

[0054] H: The first rotating mechanism 36 rotates the grasping mechanism 24 in the opposite direction based on step G, so that the grasping mechanism 24 returns to its initial position. When the next user uses it, the turntable 11 rotates at a certain angle to replace the mouthpiece in the previous position, and then the above steps are repeated to collect exhaled breaths.

[0055] Example 2

[0056] like Figure 5 and Figure 6As shown, this embodiment further illustrates Example 1. The gripping arm assembly 6 in the figure includes a horizontal plate 22, an X-axis moving mechanism 23, and a gripping mechanism 24. A limiting groove is provided on the horizontal plate 22. The X-axis moving mechanism 23 includes a limiting connecting post 25, a moving block 26, a first lead screw 27, and a second motor 28. The limiting connecting post 25 is slidably connected in the limiting groove. The moving block 26 is fixed to the top of the limiting connecting post 25. The first lead screw 27 is threadedly connected to the moving block 26. Both sides of the first lead screw 27 are connected to the top of the horizontal plate 22 through bearing seats. The output end of the second motor 28 is fixedly connected to the first lead screw 27 through a coupling. The tail end of the second motor 28 is fixedly connected to the end of the horizontal plate 22 away from the mounting housing 1 through a connecting plate. The gripping mechanism 24 is fixed to the bottom end of the limiting connecting post 25. The gripping arm assembly 6 realizes the gripping of the mouthpiece and the docking of the mouthpiece with the exhalation collector. The gripping mechanism 24 includes a second fixed plate 29, a second support plate 30, a third motor 31, a second lead screw 32, a threaded sleeve 33, and a clamping block 34. The second fixed plate 29 is fixed to the bottom end of the limiting connecting column 25. Two second support plates 30 are provided, and the two second support plates 30 are symmetrically fixed to the bottom sides of the second fixed plate 29. The second lead screw 32 is a bidirectional lead screw structure, and the second lead screw 32 is rotatably connected to the second support plate 30. The third motor 31 is fixed to the outside of one of the second support plates 30, and its output end is fixedly connected to the second lead screw 32 through a coupling. Two threaded sleeves 33 and two clamping blocks 34 are provided. The clamping block 34 is fixed to the bottom end of the threaded sleeve 33, and the threaded sleeve 33 is threaded to the outside of the second lead screw 32. A first sliding rod 35 is also fixed between the two second support plates 30, and the top of the threaded sleeve 33 is slidably sleeved on the outside of the first sliding rod 35.

[0057] When gripping the mouthpiece: by starting the third motor 31, the third motor 31 drives the second lead screw 32 to rotate, the second lead screw 32 drives the two threaded blocks to move closer to each other, the threaded blocks drive the clamping block 34 to move, and the two clamping blocks 34 move closer to each other to clamp the mouthpiece, thereby realizing the automatic gripping of the mouthpiece.

[0058] Example 3

[0059] like Figure 1 , Figure 2 and Figure 9As shown, this embodiment further illustrates Example 1. The mounting housing 1 in the figure has a mounting plate 2 fixed to one side. An exhalation collector 3 is mounted on the mounting plate 2. An auxiliary collection component 4 for automatically installing and removing the mouthpiece is mounted on the mounting housing 1. The auxiliary collection component 4 includes an arranging component 5, a gripping arm assembly 6, an adjusting component 7, and a pushing component 8. The arranging component 5 is installed inside the mounting housing 1. The gripping arm assembly 6 and the adjusting component 7 are both located above the top of the mounting plate 2. The output end of the adjusting component 7 is connected to the gripping arm assembly 6 via a transmission connection. The pushing component 8 is installed... At the bottom of the breath sampler 3, a trash can 9 is fixed to the rear side of the mounting housing 1. A sensing system 10 is installed on the side of the mounting housing 1. The pushing assembly 8 includes a U-shaped base 50, an L-shaped plate 51, an electric push rod 52, a slider 53, and a slide rail 54. The U-shaped base 50 is fixed to the top of the mounting plate 2. The L-shaped plate 51 is fixed to one side of the U-shaped base 50. The electric push rod 52 is fixed to the L-shaped plate 51, and its output end is fixedly connected to the rear side wall of the breath sampler 3. The slider 53 is fixed to the bottom of the breath sampler 3. A slide rail 54 is fixed to the inner side of the U-shaped base 50, and the slider 53 is adapted to the slide rail 54.

[0060] When the breath sampler 3 is pushed forward: by activating the electric push rod 52, the electric push rod 52 drives the breath sampler 3 to move, thereby adjusting the position of the connecting tube at the top of the breath sampler 3, making it convenient for the user to blow air.

[0061] In this scheme, a nozzle storage box is also provided on the side of the device housing facing away from the auxiliary acquisition component 4, and a funnel is connected to the bottom of the nozzle storage box. The nozzle comes out of the storage box, adjusts its posture through the funnel, and finally falls onto the conveyor belt device 59.

[0062] In this solution, the inner wall of the equipment housing is also equipped with an image recognition device, which is used to capture images of the fixed mouthpiece and automatically recognize the mouthpiece posture. After a series of image processing such as video signal acquisition, extraction, and matching, the image recognition device transmits the signal to the control system.
