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 rate. Background Art

[0002] Pathogen nucleic acid testing is a testing method that checks whether human secretion specimens contain nucleic acid of foreign invading viruses to determine whether a person is infected by a virus. Respiratory pathogen nucleic acid testing uses respiratory secretions as specimens to test and determine whether there are foreign invading viruses in the respiratory tract. In addition to respiratory disease diagnosis, it can also be used to determine diseases in other parts of the body.

[0003] In the prior art, there are still the following deficiencies when collecting specimens: 1. When collecting specimens, medical staff need to insert a pharyngeal swab into the respiratory tract to collect respiratory secretion specimens, and then put the pharyngeal swab into a specimen tube. When there are many specimens to be collected, the labor intensity of medical staff is greatly increased; 2. When a large number of specimens are collected, it is easy to make medical staff tired, and cause them to confuse the specimen labels with the specimen tubes, affecting the accuracy of subsequent tests; In view of the above problems, the present invention document proposes an automated medical sampling transportation line and method for reducing the inspection error rate.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0020] Example 1 Reference Figure 1-Figure 3 The transport line is used in the field of medical testing equipment and is mainly composed of a base 1, on the top of which a first mounting plate 2 is fixed. On one side of the first mounting plate 2, two rotating rollers 3 are rotatably connected through a bearing seat, and the two rotating rollers 3 are connected by a conveyor belt 4. A plurality of placement sleeves 5 are fixed at equal intervals on the outer wall of the conveyor belt 4, and each placement sleeve 5 is used to place a test tube 6 so as to carry the test tube 6 during the transportation process.

[0021] Reference Figure 1 , Figure 2 and Figure 5A rotating column 13 is provided above the first mounting plate 2, and a pharyngeal swab 23 is installed at one end thereof for collecting oral specimens from patients. A support plate 24 is also fixed on the top of the base 1, and a sampling hole 26 is provided in the support plate 24. The pharyngeal swab 23 passes through the sampling hole 26 so as to extend into the patient's oral cavity from the outside for specimen collection.

[0022] Reference Figure 1 , Figure 2 and Figure 8 On one side of the first mounting plate 2, a placement rack 43 is provided for storing the 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 passed through the U-shaped rack 39 through a bearing, and the placement rack 43 is placed on the top of the rotating rod 40 and rotated through the rotating structure. A plurality of jacks are provided in the placement rack 43 for inserting and fixing the test tubes 6.

[0023] 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.

[0024] Reference Figure 1 and Figure 2 The identification structure includes a camera 27 and a drag plate 25 installed on one side of the support plate 24. The camera 27 is used to collect the patient's facial data, and the drag plate 25 is used to lift the patient's chin so that the patient can stably face the sampling hole 26. An ID card reader 28 is also fixed on the top of the base 1 to read the patient's ID card information. This information is processed by the control terminal, and the inkjet printer 29 sprays a QR code on the outer wall of the test tube 6 to achieve the binding of the patient information and the test tube 6.

[0025] Reference Figure 2 , Figure 5 and Figure 6The 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. The second mounting plate 17 is provided with a rectangular groove 18, which is internally slidably connected to the wiping arm 20, and the wiping arm 20 is fixed with a mechanical claw 22 for grabbing the throat swab 23. When it is necessary to collect the 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.

[0026] Reference Figure 2 , Figure 5 and Figure 7 , the transport structure mainly realizes the automatic transport and placement of the test tube 6 through the conveyor belt 4 and the vacuum suction cup 37. The structure mainly includes the transmission and placement of the test tube 6 through the rotation of the base drive shaft 31 on the top of the first mounting plate 2. Specifically: the drive shaft 31 is connected to the rotating column 13 through a synchronous wheel and a synchronous belt transmission, ensuring that when the rotating column 13 rotates one circle, the drive shaft 31 can rotate half a circle. A rotating plate 32 is fixed at one end of the drive shaft 31, and a clearance groove 33 is provided on one side of the rotating plate 32, and a sliding block 34 is slidably connected in the clearance groove 33. A second electric push rod 35 is installed on the inner wall of one side of the clearance groove 33, and its output shaft is fixedly connected to the sliding block 34, which is used to adjust the position of the sliding block 34 and the vacuum suction cup 37 fixed on the sliding block 34. The sliding block 34 is rotatably connected to a vertical rod 36 through a fixed column, and 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 keeps the vertical rod 36 in a vertical state. When the conveyor belt 4 conveys the test tube 6 to the bottom of the vertical rod 36, the vacuum suction cup 37 contacts the top of the cap 7 and fixes the test tube 6 by vacuum adsorption. As the rotating column 13 rotates again, the driving shaft 31 and the rotating plate 32 are driven to rotate half a circle through the synchronous wheel and the synchronous belt. At this time, due to the gravity of the vertical rod 36 and the test tube 6, the test tube 6 always remains in a vertical state. After the rotating plate 32 rotates half a circle, the test tube 6 is accurately placed in the corresponding jack of the placement rack 43. When the rotating column 13 is reset and rotated, the rotating plate 32 is also reset.

[0027] Reference Figure 2 , Figure 4 , Figure 8 and Fig. 9, and the rotating structure drives the rotating rod 40 to rotate in 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 in the jack one by one. To ensure that the test tubes 6 can be placed on the placement rack 43 smoothly. 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 in 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 a plug rod 48 is slidably penetrated in the positioning block 50, one end of the plug rod 48 is fixedly connected to the support plate 46, and a second spring 49 is also 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, and 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 and the rotating rod 40 are in a locked state, the rotating rod 40 and the placement rack 43 can be driven to rotate, thereby adjusting the angle of the placement rack 43. After the hemispherical protrusion 11 is disengaged 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, but at this time the first one-way bearing 44 and the rotating rod 40 are in an active state, and the placement rack 43 no longer rotates.

[0028] Reference Figure 2 and Figure 4 The outer wall of the test tube 6 is rotatably connected with 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 be embedded in the annular groove 8, thereby increasing the stability of the seal.

[0029] Specifically, a rotating wheel 30 is rotatably connected to one side of the first mounting plate 2. When the test tube 6 is placed at a designated position, the rotating wheel 30 contacts the cap 7 and drives it to rotate until the cap 7 completely closes the test tube 6, completing the closing process of the sampling test tube 6.

[0030] 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: First, a chassis 41 is firmly fixed on the top of the rotating rod 40, and a plurality of pins 42 are evenly distributed on the top of the chassis 41. The design of these pins 42 must ensure that they are accurately matched with the pin holes at the bottom of the placement frame 43. When the placement frame 43 is assembled, the pin holes at the bottom of the placement frame 43 must be aligned with the pins 42 on the chassis 41 and inserted, so as to achieve a stable connection and positioning between the placement frame 43 and the chassis 41.

[0031] This design not only allows the chassis 41 to drive the placement rack 43 to rotate together, but also effectively limits the placement angle of the placement rack 43 through the cooperation between 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.

[0032] 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.

[0033] Example 2 refer to Figure 10-12 , based on the improvement of Example 1: a fixed cylinder 51 is fixedly installed on the side of the support plate 24 close to the first mounting plate 2. A round rod 52 is slidably connected inside the fixed cylinder 51, and one end of the round rod 52 is fixedly connected to a round ring 53. A third electric push rod 54 is fixedly installed on one side of the support plate 24, and its output shaft is directly connected to the round ring 53, which is used to push the round ring 53 and the round rod 52 to slide in the fixed cylinder 51.

[0034] A circular placement box 55 is rotatably connected inside the circular ring 53, in which a plurality of pharyngeal swabs 23 are placed, and the bottom ends of the wooden sticks of the pharyngeal swabs 23 extend below the circular placement box 55 for easy grasping. The outer wall of the circular placement box 55 is sleeved with a second one-way bearing, the inner ring of which is fixedly connected to the outer wall of the circular placement box 55, and the outer ring is fixedly sleeved with a spur gear ring 56.

[0035] One side of the ring 53 is rotatably connected to a driving rod 57 through a base, and a second gear 58 is fixed to the top of the driving rod 57, which meshes with the spur gear ring 56. At the same time, a bevel gear 61 is fixed to the bottom of the driving rod 57. A collar 59 is sleeved on the outer wall of the rotating column 13, and the collar 59 is also rotatably connected to the driving rod 57 through a base, and a bevel gear ring 60 meshing with the bevel gear 61 is rotatably connected to one side of the collar 59. The bevel gear ring 60 is slidably sleeved on the outer wall of the rotating column 13, and cooperates with the slide groove of the outer wall of the rotating column 13 through a plurality of sliders to ensure that it can slide axially while rotating.

[0036] Specifically, when the motor drives the rotating shaft 14 and the support rod 15 to rotate 90°, 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.

[0037] During the rotation of the rotating column 13, the bevel gear ring 60, the bevel gear 61, the spur gear ring 56, and the second gear 58 can precisely cooperate to drive the circular placement box 55 to rotate in one direction, thereby adjusting the position of the throat swab 23 inside it, which is convenient for the subsequent grasping of the mechanical claw 22. It is worth noting that when the rotating column 13 rotates in the opposite direction, due to the presence of the second one-way bearing, the spur gear ring 56 cannot drive the circular placement box 55 to rotate, thereby ensuring the stability and reliability of the system.

[0038] 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 gripping points for the throat swab 23 at different positions, further improving the flexibility and efficiency of the system.

[0039] In order to ensure that the rotating column 13 can stably and effectively drive the circular placement box 55 to rotate when rotating, the specific implementation is as follows: A plurality of sliding grooves are arranged on the outer wall of the rotating column 13 , and a plurality of sliding blocks matching with the sliding grooves are fixed on the inner wall of the bevel gear ring 60 .

[0040] Specifically, when the rotating column 13 rotates, the bevel gear ring 60 can be driven to rotate together through the cooperation of the slide groove and the slider. At the same time, since the driving rod 57 is connected to the bevel gear ring 60 through the collar 59, the bevel gear ring 60 will slide along the axial direction of the rotating column 13 while rotating. This design ensures that no matter what position the rotating column 13 is in, the bevel gear ring 60 can maintain a stable meshing relationship with the bevel gear 61, thereby continuously and effectively driving the circular placement box 55 to rotate.

[0041] A method for using an automated medical sampling transportation line to reduce the inspection error rate comprises the following steps: S1. When it is necessary to collect specimens, the test tube 6 is inserted into the placement sleeve 5, and the cap 7 is opened, with the opening position of the cap 7 facing the left. The identity information of the patient is read through the ID card reader 28, and the appearance of the patient is photographed through the camera 27. Then the user's chin is dragged on the drag plate 25, and the mouth is aligned with the sampling hole 26, which is convenient for the later specimen collection. The camera 27 and the ID card reader 28 transmit the information to the Internet through the control terminal. The Internet forms a two-dimensional code with the patient's information on the outer wall of the test tube 6 through the inkjet printer 29, and then the collected specimen can be placed in the test tube 6 to avoid confusion between the specimen and the patient's information; S2. During the detection, 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 oral cavity. 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 to reset. The throat swab 23 wipes the patient's oral cavity to complete the specimen collection. After that, 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 to be arranged 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. S3, the rotating roller 3 and the conveyor belt 4 cooperate to transport the test tube 6 to the right side, the rotating wheel 30 can just resist the cap 7 to complete the capping of the test tube 6 by the cap 7, the rubber ring 9 and the annular groove 8 cooperate to ensure the stability of the capping of the cap 7, the conveyor belt 4 transports the test tube 6 to the bottom of the vertical rod 36, the vacuum suction cup 37 resists the top of the cap 7, and the adsorption of the test tube 6 is completed by the vacuum suction cup 37. When the rotating column 13 rotates again to complete the next specimen collection, the rotating column 13 rotates one circle through the synchronous wheel and the synchronous belt to drive the driving shaft 31 and the rotating plate 32 to rotate half a circle, and the rotating plate 32 drives the test tube 6 to move toward the placement rack 43 through the sliding block 34. Due to the action of the vertical rod 36 and the test tube 6, when the rotating plate 32 rotates, the vertical rod 36 and the test tube 6 always remain in a vertical state. When the rotating plate 32 rotates half a circle, the test tube 6 can be placed in the placement rack 43, and the rotating column 13 is reset when the rotating plate 32 is reset; 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 at a later time. After the hemispherical protrusion 11 is disengaged 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; 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. The mechanical claw 22 is located below the circular placement box 55, and 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 through the cooperation of the bevel gear ring 60, the bevel gear 61, the spur 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 spur gear ring 56 and the circular placement box 55 cannot make the spur 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.

[0042] 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 conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
