Description

Technical Field

[0001] The present invention relates to the technical field of medical detection equipment, and in particular to an automated medical sampling and transportation line and method for reducing detection error rates. Background Art

[0002] Pathogen nucleic acid testing examines human secretion samples for the presence of viral nucleic acid to determine viral infection. Respiratory pathogen nucleic acid testing uses respiratory secretions as specimens to determine whether viruses have entered the respiratory tract. In addition to respiratory diseases, it can also be used to diagnose diseases in other areas of the body.

[0003] In the existing technology, the following deficiencies still exist when collecting specimens:

[0004] 1. When collecting specimens, medical staff need to insert a pharyngeal swab into the respiratory tract to collect respiratory secretion specimens, and then place the pharyngeal swab into a specimen tube. When a large number of specimens are collected, the labor intensity of medical staff is greatly increased;

[0005] 2. When a large number of specimens are collected, medical staff may become fatigued and confuse specimen labels with specimen tubes, affecting the accuracy of subsequent testing.

[0006] In response to the above problems, the present invention document proposes an automated medical sampling transportation pipeline and method for reducing the inspection error rate. Summary of the Invention

[0007] The purpose of the present invention is to solve the shortcomings of existing manual collection, which greatly increases the labor intensity of medical personnel and easily confuses specimen labels with specimen tubes. An automated medical sampling and transportation pipeline and method are proposed to reduce the inspection error rate.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] An automated medical sampling and transportation line for reducing the error rate of testing comprises a base, a first mounting plate fixed to the top of the base, two rotating rollers rotatably connected to one side of the first mounting plate, the two rotating rollers being connected via a conveyor belt, a plurality of placement sleeves fixed to the outer wall of the conveyor belt, and test tubes placed in the placement sleeves;

[0010] It also includes a rotating column above the first mounting plate, and a throat swab is installed at one end of the rotating column for collecting oral specimens from patients. A support plate is fixed to the top of the base, and a sampling hole is provided in the support plate. The throat swab passes through the sampling hole for collecting specimens;

[0011] The apparatus further comprises a placement rack, which is arranged on one side of the first mounting plate, a connecting plate being fixed to one end of the first mounting plate, a U-shaped rack being fixed to one side of the connecting plate, a rotating rod being rotatably passed through the U-shaped rack, the placement rack being placed on the top end of the rotating rod, and a plurality of sockets for placing test tubes being provided in the placement rack;

[0012] A vacuum suction cup is provided on one side of the first mounting plate and is used to place the test tube containing the specimen in the placement rack;

[0013] An identification structure is provided on one side of the support plate and is used to bind the patient's information to the corresponding test tube;

[0014] The collection structure is arranged on the top of the first mounting plate and is used to drive the throat swab to collect the specimen;

[0015] The transport structure is provided on the top of the first mounting plate and is used to place the test tube after collecting the specimen on the placement rack;

[0016] The rotating structure is arranged in the U-shaped frame and is used to drive the placement frame to rotate so that the test tube can be placed in the placement frame.

[0017] In one possible design, the identification structure includes a camera and a drag plate fixed on one side of the support plate, and the camera is used to collect the patient's facial data, the drag plate is used to support the patient's chin, and an ID card reader is fixed on the top of the base for reading the patient's ID card information. An inkjet printer is fixed on the top of the first mounting plate, and the inkjet printer is used to spray a QR code on the outer wall of the test tube. A control terminal is provided in the base, and the camera, ID card reader and inkjet printer are all electrically connected to the control terminal; the patient's identity information is read by the ID card reader, and the patient's appearance is photographed by the camera. The user then drags the chin on the drag plate with the mouth aligned with the sampling hole to facilitate later specimen collection. The camera and ID card reader transmit information to the Internet through the control terminal. The Internet uses the inkjet printer to form a QR code with the patient's information on the outer wall of the test tube, so that the collected specimen can be placed in the test tube to avoid confusion between the specimen and the patient's information.

[0018] In one possible design, the collection structure includes an L-shaped frame fixed to the side of the first mounting plate away from the conveyor belt, the side of the L-shaped frame close to the conveyor belt is rotatably connected to one end of the rotating column, a rotating shaft is rotatably connected in the rotating column, the outer wall of the rotating shaft is fixedly sleeved with a support rod, one end of the support rod is fixedly embedded with a first electric push rod, the output end of the first electric push rod is fixed with a second mounting plate, the second mounting plate is provided with a rectangular groove on the side away from the support rod, a wiping arm is slidably connected in the rectangular groove, a guide rod is fixed in the rectangular groove that slides through the wiping arm, the outer wall of the guide rod is sleeved with a first spring fixedly connected to the inner wall of the bottom of the rectangular groove, and the top of the first spring is fixed to the bottom of the wiping arm. The connection, the cooperation of the first spring and the guide rod is used to move the wiping arm upward and deviate from the center of the circle. A mechanical claw is fixed to the outer wall of the wiping arm for grabbing the throat swab; the output shaft of the first electric push rod pushes the second mounting plate and the wiping arm through the sampling hole and inserted into the patient's mouth, and then the motor drives the rotating column and the wiping arm to rotate. Since the wiping arm moves upward under the action of the first spring, the second mounting plate drives the wiping arm and the throat swab to rotate eccentrically, and after rotating one circle, it rotates in the opposite direction and resets. The throat swab wipes the patient's mouth to complete the specimen collection. Afterwards, the first electric push rod drives the second mounting plate to retract and reset, and the motor drives the support rod to rotate 90° through the rotating shaft to be arranged vertically downward. The mechanical claw releases the clamping of the throat swab, and the throat swab falls into the test tube.

[0019] The cam is connected to the rotating column by a synchronous wheel and a synchronous belt transmission, and the rotating column rotates one circle to drive the driving shaft to rotate half a circle. A rotating plate is fixed on one end of the driving shaft, and a clearance groove is provided on one side of the rotating plate. A sliding block is slidably connected in the clearance groove, and a second electric push rod is fixed on the inner wall of one side of the clearance groove. The output shaft of the second electric push rod is fixedly connected to the sliding block for adjusting the position of the sliding block and the vacuum suction cup so that the vacuum suction cup can place the test tube in the corresponding socket on the placement rack. One side of the sliding block is rotatably connected to the vertical rod through the fixed column. The bottom end of the vertical rod is fixedly connected to the vacuum suction cup, and the gravity of the vertical rod and the vacuum suction cup keeps the vertical rod in a vertical state; the conveyor belt transports the test tube to the bottom of the vertical rod, and the vacuum suction cup contacts the top of the cap, and the adsorption of the test tube is completed by the vacuum suction cup. When the rotating column rotates again to complete the collection of the next specimen, the rotating column rotates one circle, and the synchronous wheel and the synchronous belt drive the drive shaft and the rotating plate to rotate half a circle. The rotating plate drives the test tube to move toward the placement rack through the sliding block. Due to the action of the vertical rod and the test tube, the vertical rod and the test tube always remain in a vertical state when the rotating plate rotates. When the rotating plate rotates half a circle, the test tube can be placed in the placement rack, and the rotating plate is reset when the rotating column is reset.

After the hemispherical protrusion is disengaged from the rack, the rack is reset under the action of the second spring, and the rack drives the first gear to rotate in the opposite direction, and the first one-way bearing and the rotating rod are in an active state.

[0021] In one possible design, the outer wall of the test tube is rotatably connected to a cap, and the inner wall of the test tube is provided with an annular groove near the opening position. A rubber ring is fixed to one side of the cap, and the rubber ring cooperates with the annular groove to increase the stability of the seal between the cap and the test tube. One side of the first mounting plate is rotatably connected to a rotating wheel for pushing the cap to seal the test tube.

[0022] In one possible design, a chassis is fixed to the top of the rotating rod, a plurality of pins are provided on the top of the chassis, and a plurality of pin holes matching the pins are provided on the bottom of the placement rack for positioning the placement rack and the chassis; the cooperation between the pins and the pin holes can not only enable the chassis to drive the placement rack to rotate, but also limit the angle at which the placement rack is placed, so that the jacks on the placement rack can cooperate with the vertical rods to receive the test tubes in the later stage.

[0023] The cam is fixed with a first end in contact with the first end of the driving member and a second end in contact with the first gear and a third end in contact with the first gear and a third end in contact with the first gear. The bottom end of the driving rod is fixed with a bevel gear, and the outer wall of the rotating column is provided with a collar, and the collar is rotatably connected to the driving rod through the base.

The first electric push rod and the mechanical claw cooperate to complete the grabbing of the pharyngeal swab in the circular placement box; in addition, when the rotating column rotates, the circular placement box is driven to rotate by the cooperation of the bevel gear ring, the bevel gear, the spur gear ring and the second gear, and the position of the circular placement box is adjusted to facilitate the later mechanical claw to grab the pharyngeal swab. When the rotating column rotates in the opposite direction, the second one-way bearing between the spur gear ring and the circular placement box cannot cause the spur gear ring to drive the circular placement box to rotate; in addition, the output shaft of the third electric push rod can push the circular placement box to move, so that the mechanical claw can change its position to grab the pharyngeal swab.

[0024] In a possible design, the outer wall of the rotating column is provided with a plurality of sliding grooves, and the inner wall of the bevel gear ring is fixed with a plurality of sliders, and the sliders are slidably arranged in the sliding grooves; when the rotating column rotates, the bevel gear ring is driven to rotate through the sliding grooves and the sliders, and the driving rod drives the bevel gear ring to slide along the axial direction of the rotating column through the sleeve ring, so that the rotating column can always drive the circular placement box to rotate.

[0026] S1. Insert the test tube into the placement sleeve, open the cap and point it to the left. Use the ID card reader and camera to record the patient's identity information and appearance. Place the patient's chin on the slide and align their mouth with the sampling hole to take the sample. The information is automatically transmitted to the Internet, and the inkjet printer generates a QR code on the outer wall of the test tube to ensure the accuracy of the specimen information.

[0027] S2: The first electric push rod pushes the wiping arm into the patient's mouth, and the motor drives it to rotate eccentrically to complete the collection of the throat swab specimen; after collection, the first electric push rod resets, the motor adjusts the direction of the support rod, and the mechanical claw releases the throat swab into the test tube;

[0028] S3. The conveyor belt drives the test tube to the capping position, and the rotating wheel automatically caps it; the vacuum suction cup absorbs the test tube and rotates with the rotating plate to the top of the placement rack and places it accurately;

[0029] S4. When the placement sleeve moves, the hemispherical bump triggers the rack, driving the placement frame to rotate to a suitable angle; after the rack is reset, the first one-way bearing is unlocked, and the placement frame maintains the current angle;

[0030] S5. Driven by the motor, the mechanical claw cooperates with the first electric push rod to grab a new throat swab from the circular placement box; the rotating column adjusts the position of the circular placement box through gear transmission to facilitate the mechanical claw to grab; the third electric push rod can push the circular placement box to increase the flexibility of grabbing.

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Example 1

[0051] Reference Figure 1-Figure 3 The transport line, used in the field of medical testing equipment, primarily comprises a base 1, with a first mounting plate 2 fixed to its top. Two rotating rollers 3 are rotatably connected to one side of the first mounting plate 2 via a bearing block. These two rollers 3 are connected by a conveyor belt 4. Multiple placement sleeves 5 are fixed at equal intervals on the outer wall of the conveyor belt 4. Each sleeve 5 is used to hold a test tube 6, ensuring that the test tube 6 is carried during transport.

[0052] Reference Figure 1 、 Figure 2 and Figure 5 Above the first mounting plate 2, a rotating column 13 is mounted on one end of which is a pharyngeal swab 23 for collecting oral specimens from patients. A support plate 24 is also fixed to the top of the base 1. This support plate 24 defines a sampling hole 26, through which the pharyngeal swab 23 passes, allowing it to be inserted into the patient's oral cavity for specimen collection.

[0053] Reference Figure 1 、 Figure 2 and Figure 8 On one side of the first mounting plate 2, a storage rack 43 is provided for storing collected test tubes 6. A connecting plate 38 is fixed to one end of the first mounting plate 2, and a U-shaped rack 39 is fixed to one side of the connecting plate 38. A rotating rod 40 is rotatably inserted through the U-shaped rack 39 via a bearing. The storage rack 43 is placed on top of the rotating rod 40 and rotates via a rotating structure. The storage rack 43 has multiple sockets for inserting and securing the test tubes 6.

[0054] Reference Figure 2 and Figure 7 In order to remove the collected specimen test tube 6 from the conveyor belt 4 and place it on the placement rack 43, a vacuum suction cup 37 is provided as an auxiliary tool. The vacuum suction cup 37 absorbs the test tube 6 and moves it to the top of the placement rack 43, and then releases the test tube 6 to make it fall into the insertion hole.

[0055] Reference Figure 1 and Figure 2The identification structure includes a camera 27 and a carriage 25 mounted on one side of a support plate 24. Camera 27 captures the patient's facial data, while carriage 25 supports the patient's chin, allowing them to face the sampling hole 26 stably. An ID card reader 28 is also mounted on the top of the base 1 to read the patient's ID card information. This information is processed by a control terminal, and a QR code is printed on the outer wall of the test tube 6 by an inkjet printer 29, effectively binding the patient's information to the test tube 6.

[0056] Reference Figure 2 、 Figure 5 and Figure 6 The collection structure mainly includes an L-shaped frame 12, a rotating column 13, a rotating shaft 14, a support rod 15, a first electric push rod 16, a second mounting plate 17, a rectangular groove 18, a guide rod 19, a first spring 21, a wiping arm 20 and a mechanical claw 22. Among them, the L-shaped frame 12 is fixed on the side of the first mounting plate 2 away from the conveyor belt 4, one end of the rotating column 13 is rotatably connected to the L-shaped frame 12, and the other end is connected to the support rod 15 through the rotating shaft 14. The first electric push rod 16 is fixed on the support rod 15, and its output end is connected to the second mounting plate 17. A rectangular groove 18 is provided on the second mounting plate 17, and the wiping arm 20 is slidably connected inside. The wiping arm 20 is fixed with a mechanical claw 22 for grabbing the throat swab 23. When it is necessary to collect a specimen, the first electric push rod 16 pushes the wiping arm 20 and the throat swab 23 into the patient's mouth, and the specimen is collected by rotating the rotating column 13.

[0057] Reference Figure 2 、 Figure 5 and Figure 7The transport mechanism primarily utilizes a conveyor belt 4 and vacuum suction cups 37 to automatically transport and place test tubes 6. This mechanism primarily involves the rotation of a base drive shaft 31 on top of the first mounting plate 2 to achieve the transfer and placement of test tubes 6. Specifically, the drive shaft 31 is connected to the rotating column 13 via a synchronous pulley and belt, ensuring that for every full rotation of the rotating column 13, the drive shaft 31 rotates half a full rotation. A rotating plate 32 is secured to one end of the drive shaft 31. A clearance groove 33 is defined on one side of the rotating plate 32, within which a sliding block 34 is slidably connected. A second electric push rod 35 is mounted on the inner wall of the clearance groove 33. Its output shaft is fixedly connected to the sliding block 34 and is used to adjust the position of the sliding block 34 and the vacuum suction cup 37 attached to it. The sliding block 34 is rotatably connected to a vertical rod 36 via a fixed column. The bottom end of the vertical rod 36 is fixedly connected to the vacuum suction cup 37. The gravity of the vertical rod 36 and the vacuum suction cup 37 maintains the vertical rod 36 in a vertical position. When the conveyor belt 4 transports the test tube 6 to below the vertical rod 36, the vacuum suction cup 37 contacts the top of the cap 7, securing the test tube 6 through vacuum suction. As the rotating column 13 rotates again, the drive shaft 31 and the rotating plate 32 rotate half a turn via the synchronous pulley and synchronous belt. At this point, the test tube 6 remains vertical due to the gravity of the vertical rod 36 and the test tube 6. After the rotating plate 32 rotates half a turn, the test tube 6 is precisely placed in the corresponding socket of the placement rack 43. When the rotating column 13 returns to its original position, the rotating plate 32 also returns to its original position.

[0058] Reference Figure 2 、 Figure 4 、 Figure 8 and Figure 9, and the rotating structure drives the rotating rod 40 to rotate inside the U-shaped frame 39 through a motor, thereby driving the placement rack 43 to rotate so that the test tubes 6 can be placed into the insertion holes one by one. To ensure that the test tubes 6 can be placed smoothly on the placement rack 43. The rotating structure includes a first one-way bearing 44 sleeved on the outer wall of the rotating rod 40, and the bearing is located inside the U-shaped frame 39. The outer ring of the first one-way bearing 44 is fixed with a first gear 45, and the inner ring is fixed to the outer wall of the rotating rod 40. This design enables the first gear 45 to drive the rotating rod 40 to rotate in one direction. A support plate 46 is slidably connected to the inner wall of one side of the U-shaped frame 39, and a rack 47 meshing with the first gear 45 is fixed on the support plate 46. In order to ensure the reset of the rack 47, a positioning block 50 is also provided in the U-shaped frame 39, and an insertion rod 48 is slidably passed through the positioning block 50. One end of the insertion rod 48 is fixedly connected to the support plate 46, and a second spring 49 is provided between the two. When the conveyor belt 4 drives the placement sleeve 5 to move to the side of the rotating roller 3, the hemispherical protrusion 11 installed on the fixed ring 10 on the outer wall of the placement sleeve 5 pushes the rack 47 to move to the right. The rack 47 cooperates with the first gear 45 to drive the first one-way bearing 44 to rotate. Since the first one-way bearing 44 is locked with the rotating rod 40, it can drive the rotating rod 40 and the placement rack 43 to rotate, thereby adjusting the angle of the placement rack 43. After the hemispherical protrusion 11 disengages from the rack 47, the rack 47 is reset under the action of the second spring 49, driving the first gear 45 to rotate in the opposite direction. However, at this time, the first one-way bearing 44 and the rotating rod 40 are in a movable state, and the placement rack 43 no longer rotates.

[0059] Reference Figure 2 and Figure 4 The outer wall of the test tube 6 is rotatably connected to a cap 7, and an annular groove 8 is provided on the inner wall of the test tube 6 near the opening. A rubber ring 9 is fixed to one side of the cap 7. When the cap 7 is rotated to fit tightly with the opening of the test tube 6, the rubber ring 9 will fit into the annular groove 8, thereby increasing the stability of the seal.

[0060] Specifically, a rotating wheel 30 is rotatably connected to one side of the first mounting plate 2. When the test tube 6 is placed in the designated position, the rotating wheel 30 contacts the cap 7 and pushes it to rotate until the cap 7 completely closes the test tube 6, completing the sealing process of the sampling test tube 6.

[0061] Reference Figure 2 and Figure 8 In order to achieve a stable connection and angle limitation between the rotating rod 40 and the placement frame 43, the specific implementation is as follows:

[0062] First, a chassis 41 is securely fastened to the top of the rotating rod 40. Multiple pins 42 are evenly distributed across the top of the chassis 41. These pins 42 are designed to precisely mate with the pin holes on the bottom of the mounting bracket 43. During assembly, the pin holes on the bottom of the mounting bracket 43 must be aligned with the pins 42 on the chassis 41 and inserted, ensuring a secure connection and positioning between the mounting bracket 43 and the chassis 41.

[0063] This design not only allows the chassis 41 to rotate with the placement rack 43, but also effectively limits the placement angle of the placement rack 43 through the cooperation of the pin 42 and the pin hole. This feature is particularly important in subsequent operations because it ensures that the socket on the placement rack 43 can accurately cooperate with the vertical rod 36, thereby smoothly receiving the test tube 6, significantly reducing the inspection error rate caused by position deviation.

[0064] Through the above specific implementation methods, the automated medical sampling and transportation pipeline of the present invention can effectively reduce the inspection error rate and improve the efficiency and accuracy of sampling and transportation.

[0065] Example 2

[0066] refer to Figure 10-12 , based on the improvement of Example 1: A fixed cylinder 51 is fixedly mounted on the side of the support plate 24 near the first mounting plate 2. A round rod 52 is slidably connected to the interior of the fixed cylinder 51, and a circular ring 53 is fixedly connected to one end of the circular rod 52. A third electric push rod 54 is fixedly mounted on one side of the support plate 24, and its output shaft is directly connected to the circular ring 53, which is used to push the circular ring 53 and the round rod 52 to slide within the fixed cylinder 51.

[0067] A circular storage box 55 is rotatably connected to the inner portion of the ring 53. Multiple throat swabs 23 are placed within this box, with the bottom ends of the wooden sticks of the throat swabs 23 extending below the circular storage box 55 for easy access. A second one-way bearing is mounted on the outer wall of the circular storage box 55. The inner ring of the second one-way bearing is fixedly connected to the outer wall of the circular storage box 55, while the outer ring is fixedly mounted with a spur gear ring 56.

[0068] One side of the circular ring 53 is rotatably connected to a drive rod 57 via a base. A second gear 58 is fixed to the top of the drive rod 57, which meshes with the spur gear ring 56. A bevel gear 61 is also fixed to the bottom of the drive rod 57. A collar 59 is sleeved around the outer wall of the rotating column 13. This collar 59 is also rotatably connected to the drive rod 57 via a base. A bevel gear ring 60 is rotatably connected to one side of the collar 59, which meshes with the bevel gear 61. The bevel gear ring 60 is slidably mounted on the outer wall of the rotating column 13 and engages with grooves in the outer wall of the rotating column 13 via multiple sliders, ensuring axial sliding during rotation.

[0069] Specifically, when the motor drives the rotating shaft 14 and the support rod 15 to rotate 90 degrees, the support rod 15 drives the mechanical claw 22 to rotate to the bottom of the circular placement box 55. At this time, the first electric push rod 16 cooperates with the mechanical claw 22 to complete the grabbing action of the pharyngeal swab 23 in the circular placement box 55.

[0070] During the rotation of the rotating column 13, the precise coordination of the bevel gear ring 60, bevel gear 61, spur gear ring 56, and second gear 58 drives the circular placement box 55 to rotate unidirectionally, thereby adjusting the position of the throat swab 23 inside it and facilitating subsequent grasping by the mechanical claw 22. It is worth noting that when the rotating column 13 rotates in the opposite direction, the presence of the second one-way bearing prevents the spur gear ring 56 from driving the circular placement box 55 to rotate, thus ensuring the stability and reliability of the system.

[0071] In addition, the output shaft of the third electric push rod 54 can push the ring 53 and the circular placement box 55 to move as a whole, providing the mechanical claw 22 with grabbing points for the throat swab 23 at different positions, further improving the flexibility and efficiency of the system.

[0072] In order to ensure that the rotating column 13 can stably and effectively drive the circular placement box 55 to rotate during rotation, the specific implementation is as follows:

[0073] A plurality of sliding grooves are provided on the outer wall of the rotating column 13 , and a plurality of sliding blocks matching the sliding grooves are fixed on the inner wall of the bevel gear ring 60 .

[0074] Specifically, when the rotating column 13 rotates, the bevel gear ring 60 rotates along with it through the cooperation of the sliding groove and the slider. At the same time, because the driving rod 57 is connected to the bevel gear ring 60 via the collar 59, the bevel gear ring 60 also slides axially along the rotating column 13 as it rotates. This design ensures that regardless of the position of the rotating column 13, the bevel gear ring 60 maintains a stable meshing relationship with the bevel gear 61, thereby continuously and effectively driving the circular placement box 55 to rotate.

[0075] A method for using an automated medical sampling and transportation pipeline to reduce the error rate of testing comprises the following steps:

[0076] S1. When a specimen needs to be collected, the test tube 6 is inserted into the placement sleeve 5 and the cap 7 is opened with the opening of the cap 7 facing the left. The patient's identity information is read through the ID card reader 28, and the patient's appearance is photographed through the camera 27. The user then places his chin on the drag plate 25 and aligns his mouth with the sampling hole 26 to facilitate subsequent specimen collection. The camera 27 and the ID card reader 28 transmit information to the Internet through the control terminal. The Internet uses the inkjet printer 29 to print the patient's information as a QR code on the outer wall of the test tube 6. The collected specimen can then be placed in the test tube 6 to avoid confusion between the specimen and the patient's information.

[0077] S2. During the test, the output shaft of the first electric push rod 16 pushes the second mounting plate 17 and the wiping arm 20 through the sampling hole 26 and inserts into the patient's mouth. Then the motor drives the rotating column 13 and the wiping arm 20 to rotate. Since the wiping arm 20 moves upward under the action of the first spring 21, the second mounting plate 17 drives the wiping arm 20 and the throat swab 23 to rotate eccentrically, and after rotating one circle, it rotates in the opposite direction and resets. The throat swab 23 wipes the patient's mouth to complete the specimen collection. Afterwards, the first electric push rod 16 drives the second mounting plate 17 to retract and reset. The motor drives the support rod 15 to rotate 90° through the rotating shaft 14 and arranges it vertically downward. The mechanical claw 22 releases the clamping of the throat swab 23, and the throat swab 23 falls into the test tube 6.

[0078] The test tube 6 is placed in the placement rack 43 and the rotating column 13 is reset when the rotating column 13 is reset.

[0079] S4. As the conveyor belt 4 drives the placement sleeve 5 to move, when the placement sleeve 5 runs to one side of the rotating roller 3, the hemispherical protrusion 11 on the outer wall of the placement sleeve 5 pushes the rack 47 to move to the right, and the rack 47 cooperates with the first gear 45 to drive the first one-way bearing 44 to rotate. The first one-way bearing 44 and the rotating rod 40 are in a locked state, driving the rotating rod 40 and the placement rack 43 to rotate, adjusting the angle of the placement rack 43 so that the test tube 6 can be placed on the placement rack 43 later. After the hemispherical protrusion 11 disengages from the rack 47, the rack 47 is reset under the action of the second spring 49, and the rack 47 drives the first gear 45 to rotate in the opposite direction, and the first one-way bearing 44 and the rotating rod 40 are in an active state;

[0080] S5. When the mechanical claw 22 grabs a new throat swab 23 for specimen collection, the motor drives the rotating shaft 14 and the support rod 15 to rotate 90°, and the support rod 15 drives the mechanical claw 22 to rotate upward, and the mechanical claw 22 is located below the circular placement box 55. The first electric push rod 16 cooperates with the mechanical claw 22 to complete the grabbing of the throat swab 23 in the circular placement box 55; in addition, when the rotating column 13 rotates, the circular placement box 55 is driven to rotate by the cooperation of the bevel gear ring 60, the bevel gear 61, the straight gear ring 56, and the second gear 58, and the position of the circular placement box 55 is adjusted to facilitate the mechanical claw 22 to grab the throat swab 23 later. When the rotating column 13 rotates in the opposite direction, the second one-way bearing between the straight gear ring 56 and the circular placement box 55 cannot make the straight gear ring 56 drive the circular placement box 55 to rotate; in addition, the output shaft of the third electric push rod 54 can push the circular placement box 55 to move, so that the mechanical claw 22 can change its position to grab the throat swab 23.

[0081] However, as is well known to those skilled in the art, the working principles and wiring methods of the third electric push rod 54, the second electric push rod 35, the first electric push rod 16, the inkjet printer 29, the ID card reader 28 and the camera 27 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0082] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
