Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a container rotation mechanism, a barcode scanning device, and a medical testing instrument. Background Technology

[0002] With the rapid development of medical technology, the automation level of medical testing instruments is gradually increasing. During the sample introduction process, a transmission mechanism transports blood collection tubes placed on a tube rack to the designated sampling position for sampling and testing. A barcode containing information about the sample is usually affixed to the blood collection tube. A rotating mechanism drives the blood collection tube to rotate, and a barcode scanner identifies and extracts the information from the barcode on the blood collection tube, sending it to the instrument.

[0003] The rotating mechanisms in related technologies include the following structures: The first type uses friction between the parts and the side of the blood collection tube to rotate the tube. The drawback of this mechanism is that it cannot precisely control the rotation angle of the blood collection tube, which may lead to slippage or require multiple rotations for scanning, resulting in low scanning accuracy. The second type involves pressing the top of the blood collection tube to rotate it. Most of these rotating scanning devices use two drives: one controls the vertical movement of the pressing assembly, and the other controls the rotation of the blood collection tube. This requires two drives, increasing cost, and the two drives result in a large space footprint, making the overall machine less compact. The third type involves slidably mounting a motor, lead screw, and nut on a linear guide rail. The end of the lead screw has a connector that engages with a container. Two optical sensors are used to position the motor and nut. When the connector engages with the container, the motor drives the container to rotate, thus achieving scanning. Although the spatial structure is relatively compact, it requires two sensors to complete the detection action, making the structure and control relatively complex and costly. Utility Model Content

[0004] Therefore, it is necessary to overcome the shortcomings of the existing technology and provide a container rotation mechanism, a barcode scanning device, and a medical testing instrument that can improve the accuracy of rotational barcode scanning, reduce costs, and have a compact and simple structure.

[0005] A container rotating mechanism, comprising:

[0006] The fixing base is provided with screw holes;

[0007] An electric motor, which is slidably mounted on the fixed base;

[0008] A linkage shaft is coaxially connected to the rotating shaft of the motor. The linkage shaft passes through the screw hole, and the outer wall of the linkage shaft is provided with a thread that matches the screw hole. The sliding direction of the motor is parallel to the axis of the linkage shaft.

[0009] An elastic component, wherein the elastic component is connected to the linkage shaft; and

[0010] A clamping element connected to the elastic component, the clamping element having a recess adapted to the top of the container.

[0011] In one embodiment, the elastic component includes a rotating shaft, a rotating sleeve, and an elastic element; the rotating shaft and the rotating sleeve are fitted together and can slide along the axial direction of the rotating shaft, and the rotating shaft can drive the rotating sleeve to rotate synchronously; the elastic element is connected between the rotating shaft and the rotating sleeve; one of the rotating shaft and the rotating sleeve is coaxially connected to the linkage shaft, and the other of the rotating shaft and the rotating sleeve is connected to the clamping element.

[0012] In one embodiment, the rotating shaft is provided with a guide member, and the side wall of the rotating sleeve is provided with a slide rail extending in a direction parallel to its axial direction, the guide member being slidably disposed in the slide rail; and / or,

[0013] The outer wall of the rotating shaft is provided with a first positioning part, the outer wall of the rotating sleeve is provided with a second positioning part, the elastic element is a spring, the spring is sleeved on the outside of the rotating shaft, and the opposite ends of the spring abut against the first positioning part and the second positioning part respectively.

[0014] In one embodiment, the container rotation mechanism further includes a guide rail and a slider. The guide rail is connected to the fixed base, and the extension direction of the guide rail is parallel to the axial direction of the linkage shaft. The slider is slidably disposed on the guide rail, and the motor is connected to the slider.

[0015] In one embodiment, the container rotation mechanism further includes a nut connected to the fixed base, and a screw hole formed in the nut.

[0016] In one embodiment, the container rotation mechanism further includes a protective shell connected to the fixed base, and the motor's wires are fixedly threaded through the protective shell.

[0017] A barcode scanning device includes the aforementioned container rotation mechanism, a support, and a barcode scanner. The support is used to mount the container and has a notch. The barcode scanner is arranged facing the notch. When the container rotation mechanism rotates the container, causing the code on the side wall of the container to rotate to the notch, the barcode scanner can identify the code on the side wall of the container.

[0018] In one embodiment, the scanning device further includes a controller; the container rotation mechanism further includes a position detection component connected to the fixed base, the position detection component being used to obtain whether the clamping member is located at the target position, and to transmit a signal that the clamping member is located at the target position to the controller, the position detection component, the motor and the barcode scanner being electrically connected to the controller.

One of the reset optocoupler and the stop is disposed on the fixed base, and the other is disposed on the motor.

[0020] A medical testing instrument, including the aforementioned barcode scanning device.

[0021] In the aforementioned container rotation mechanism, barcode scanning device, and medical testing instrument, the motor drives the linkage shaft to rotate during use. Since the linkage shaft passes through a screw hole, its rotation correspondingly causes the motor to slide along the fixed base and moves the clamping component toward the container. The clamping component then fits onto the top of the container through a recess. As the clamping component continues to rotate, it correspondingly drives the container to rotate, thus completing the barcode scanning action during the container's rotation. Simultaneously, the elastic component connecting the clamping component and the linkage shaft buffers the axial movement of the linkage shaft, thereby reducing the clamping force on the top of the container and preventing damage to the container. Therefore, on the one hand, the clamping component presses against the top of the container to drive the container to rotate. Compared with the method of contacting the side of the container and driving it to rotate, there will be no slippage, which can improve the accuracy of rotation scanning. Moreover, the motor is located above the container, making the structure compact. On the other hand, a single motor and linkage shaft can complete the movement close to the top of the container and drive the container to rotate. The elastic component makes the clamping component adaptive when it contacts the top of the container, eliminating the need for at least two sensors. The structure is compact and simple, reducing costs and making it suitable for rotating containers of various heights. Attached Figure Description

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] It should be noted that the containers in this embodiment include, but are not limited to, test tubes or biochemical cups. Specifically, this embodiment uses test tubes as an example for description, but it is not limited to this.

[0032] See Figures 1 to 3 An embodiment of this application provides a container rotation mechanism, comprising: a fixed base 10, a motor 20, a linkage shaft 30, an elastic component 40, and a clamping member 50. The fixed base 10 has a threaded hole. The motor 20 is slidably mounted on the fixed base 10. The linkage shaft 30 is coaxially connected to the rotating shaft of the motor 20, passes through the threaded hole, and has a thread on its outer wall that matches the threaded hole. The sliding direction of the motor 20 is parallel to the axis of the linkage shaft 30. The elastic component 40 is connected to the linkage shaft 30. The clamping member 50 is connected to the elastic component 40 and has a recess 51 that adapts to the top of the container 60.

[0033] In the aforementioned container rotation mechanism, the motor 20 drives the linkage shaft 30 to rotate. Since the linkage shaft 30 passes through a screw hole, its rotation correspondingly drives the motor 20 to slide along the fixed base 10 and moves the clamping member 50 towards the container 60. The clamping member 50 is then fitted onto the top of the container 60 through the recess 51. As the clamping member 50 continues to rotate, it correspondingly drives the container 60 to rotate, allowing the barcode scanning action to be completed during the rotation of the container 60. Simultaneously, the elastic component 40 connecting the clamping member 50 and the linkage shaft 30 buffers the axial movement of the linkage shaft 30, thereby reducing the clamping force of the clamping member 50 on the top of the container 60 and preventing damage to the container 60. Therefore, on the one hand, the clamping member 50 and the top of the container 60 are clamped together to drive the container 60 to rotate. Compared with the method of contacting the side of the container 60 and driving the container 60 to rotate, there will be no slippage, which can improve the accuracy of rotation scanning. Moreover, the motor 20 is located above the container 60, and the structure is compact. On the other hand, a single motor 20 and linkage shaft 30 can complete the movement and drive the container 60 to rotate in the direction close to the top of the container 60. Furthermore, the elastic component 40 makes the clamping member 50 adaptive when it contacts the top of the container 60. It can eliminate the need for at least two sensors, making the structure compact and simple, reducing costs, and suitable for rotating containers 60 of various heights.

[0034] Optionally, the linkage shaft 30 may include, but is not limited to, a lead screw.

[0035] Please see Figure 3 For example, the elastic component 40 includes a rotating shaft 41, a rotating sleeve 42, and an elastic element 43. The rotating shaft 41 and the rotating sleeve 42 are fitted together and can slide along the axial direction of the rotating shaft 41. The rotating shaft 41 can drive the rotating sleeve 42 to rotate synchronously. The elastic element 43 is connected between the rotating shaft 41 and the rotating sleeve 42. One of the rotating shaft 41 and the rotating sleeve 42 is coaxially connected to the linkage shaft 30, and the other of the rotating shaft 41 and the rotating sleeve 42 is connected to the clamping member 50. Thus, after the clamping member 50 presses down against the top of the container 60, the clamping member 50 cannot continue to move downward. At the same time, the motor 20 continues to drive the linkage shaft 30 to rotate. Since the rotating shaft 41 and the rotating sleeve 42 are fitted together and can slide along the axial direction of the rotating shaft 41, the rotating shaft 41 can drive the rotating sleeve 42 to rotate synchronously. The elastic element 43 is connected between the rotating shaft 41 and the rotating sleeve 42. In this way, while the pressing element 50 drives the container 60 to rotate, the elastic element 43 can be adaptively compressed to prevent the pressing element 50 from continuing to press down and causing damage to the container 60.

[0036] It should be noted that there are many specific structural forms in which the rotating shaft 41 can drive the rotating sleeve 42 to rotate synchronously. For example, the axial cross-sectional profile of the rotating shaft 41 is a non-circular shape such as a polygon, ellipse or irregular shape, and the circumferential cross-sectional profile of the rotating sleeve 42 corresponds to the cross-sectional profile of the rotating shaft 41.

[0037] It should be noted that the "rotation shaft 41" in this embodiment can be a part of the "linkage shaft 30", that is, the "rotation shaft 41" and the "other parts of the linkage shaft 30" are integrally formed; or it can be an independent component that can be separated from the "other parts of the linkage shaft 30", that is, the "rotation shaft 41" can be manufactured independently and then combined with the "other parts of the linkage shaft 30" to form a whole.

[0038] Please see Figure 6 , Figure 6 The rotating shaft 41 and the linkage shaft 30 shown in the diagram are an integral structure.

[0039] Please see Figure 3 In this embodiment, a guide member 411 is provided on the rotating shaft 41. The guide member 411 is, for example, a limiting pin or a limiting rod. A slide rail 421 extending parallel to its axial direction is provided on the side wall of the rotating sleeve 42, and the guide member 411 slides through the slide rail 421. Thus, under the guidance of the guide member 411, the rotating sleeve 42 and the rotating shaft 41 slide together in the axial direction, and when the rotating shaft 41 rotates, it drives the rotating sleeve 42 to rotate synchronously, thereby realizing the rotation of the container 60 and ensuring the stability of the rotation.

[0040] For example, the slide 421 is configured with closed structures at both ends along its axial direction, such that the guide 411 is confined within the slide 421 and moves between the two ends of the slide 421.

[0041] Please see Figure 3 For example, the outer wall of the rotating shaft 41 is provided with a first positioning part 412, and the outer wall of the rotating sleeve 42 is provided with a second positioning part 422. The elastic element 43 is configured as a spring, which is sleeved on the outside of the rotating shaft 41, and the opposite ends of the spring abut against the first positioning part 412 and the second positioning part 422 for positioning.

[0042] Optionally, the clamping element 50 may include, but is not limited to, a clamping cover. The clamping cover encloses to form a recess 51. The clamping element 50 may include, but is not limited to, being made of an elastic material, providing good stability when clamping the top of the container 60.

[0043] Please see Figure 2 , Figure 4 and Figure 5For example, the container rotation mechanism also includes a guide rail 70 and a slider 80. The guide rail 70 is connected to the fixed base 10, and the extension direction of the guide rail 70 is parallel to the axial direction of the linkage shaft 30. The slider 80 is slidably disposed on the guide rail 70, and the motor 20 is connected to the slider 80. Thus, when the motor 20 is working, under the guidance of the slider 80, the motor 20 can slide stably along the guide rail 70, realizing vertical movement.

[0044] It should be noted that the connection between the motor 20 and the slider 80 can be either direct or indirect. In this embodiment, to facilitate the connection between the motor 20 and the slider 80, the container rotation mechanism also includes a mounting frame 91. The mounting frame 91 and the slider 80 are connected and fixed by fasteners such as pins, rivets, screws, or bolts, and the motor 20 is fixedly mounted on the mounting frame 91.

[0045] Please see Figure 2 and Figure 3 For example, the container rotation mechanism also includes a nut 92, which is connected to the fixed base 10, and a screw hole is formed on the nut 92.

[0046] It should be noted that the "nut 92" in this embodiment can be a part of the "fixed seat 10", that is, the "nut 92" is integrally formed with the "other parts of the fixed seat 10"; or it can be an independent component that can be separated from the "other parts of the fixed seat 10", that is, the "nut 92" can be manufactured independently and then combined with the "other parts of the fixed seat 10" to form a whole.

[0047] Please see Figure 2 For example, the container rotation mechanism also includes a protective housing 93. The protective housing 93 is connected to the fixed base 10, and the wires of the motor 20 are fixedly passed through the protective housing 93. In this way, when the motor 20 is working, the wires of the motor 20 are fixedly passed through the protective housing 93, thereby being protected by the protective housing 93 and avoiding damage. In addition, it can also prevent the wires of the motor 20 from moving to the linkage shaft 30 when the motor 20 moves up and down, thus preventing the linkage shaft 30 from affecting its normal operation.

[0048] Optionally, the protective shell 93 may include, but is not limited to, sheet metal parts.

[0049] Please see Figure 1 and Figure 7 Another embodiment of this application provides a barcode scanning device, including the container rotation mechanism of any of the above embodiments, and also includes a bracket 94 and a barcode scanner. The bracket 94 is used to mount the container 60, and the bracket 94 has a notch. The barcode scanner is arranged facing the notch. When the container rotation mechanism rotates the container 60, so that the code on the side wall of the container 60 rotates to the notch, the barcode scanner can identify the code on the side wall of the container 60.

[0050] The coding is not limited to the side wall of container 60. For example, the bracket 94 is coded. A barcode scanner can also be used to identify the coding on bracket 94.

[0051] In use, the aforementioned barcode scanning device involves the motor 20 driving the linkage shaft 30 to rotate. Since the linkage shaft 30 passes through a screw hole, its rotation causes the motor 20 to slide along the fixed base 10 and the clamping member 50 to move towards the container 60. The clamping member 50 is then fitted onto the top of the container 60 through the recess 51. As the clamping member 50 continues to rotate, it correspondingly drives the container 60 to rotate, thus completing the barcode scanning action during the rotation of the container 60. Simultaneously, the elastic component 40 connecting the clamping member 50 and the linkage shaft 30 buffers the axial movement of the linkage shaft 30, thereby reducing the clamping force of the clamping member 50 on the top of the container 60 and preventing damage to the container 60. Therefore, on the one hand, the clamping member 50 and the top of the container 60 are clamped together to drive the container 60 to rotate. Compared with the method of contacting the side of the container 60 and driving the container 60 to rotate, there will be no slippage, which can improve the accuracy of rotation scanning. Moreover, the motor 20 is located above the container 60, and the structure is compact. On the other hand, a single motor 20 and linkage shaft 30 can complete the movement and drive the container 60 to rotate in the direction close to the top of the container 60. Furthermore, the elastic component 40 makes the clamping member 50 adaptive when it contacts the top of the container 60. It can eliminate the need for at least two sensors, making the structure compact and simple, reducing costs, and suitable for rotating containers 60 of various heights.

[0052] Optionally, the encoding may include, but is not limited to, QR codes, barcodes, or other recognizable patterns and numbers, as long as they can be recognized by a scanner. The specific form is not limited here and can be flexibly adjusted and set according to actual needs.

[0053] Please see Figure 4 and Figure 5 For example, the barcode scanning device also includes a controller. The container rotation mechanism also includes a position detection component 95, which is connected to the fixed base 10. The position detection component 95 is used to determine whether the clamping member 50 is in the target position and transmits a signal indicating that the clamping member 50 is in the target position to the controller. The position detection component 95, the motor 20, and the barcode scanner are all electrically connected to the controller. In this way, the position detection component 95, the motor 20, and the barcode scanner work in coordination under the control of the controller, achieving a high degree of automation and eliminating the need for manual operation. Furthermore, using a single position detection component 95 can accurately control and adjust the pressing position of the clamping member 50, eliminating the need for at least two sensors, resulting in a more compact structure and reduced cost.

[0054] Specifically, when the clamping member 50 is in the target position, the position detection component 95 detects the clamping member 50 and sends a signal indicating that the clamping member 50 is in the target position to the controller. The controller then controls the motor 20 to reset and stop moving based on the signal indicating that the clamping member 50 has reached the target position. When scanning the container 60, because the motor 20 is reset, it can precisely adjust and control the pressing position of the clamping member 50. The controller can simultaneously control the barcode scanner to operate while the clamping member 50 and the container 60 are engaged and rotating, and the scanner accordingly acquires and identifies the code on the side wall of the container 60.

[0055] The target position includes, but is not limited to, the initial position, the final position, or other positions of the clamping member 50, which can be flexibly adjusted and set according to actual needs. In this embodiment, the target position is specifically taken as the initial position. In addition, the motor 20 is specifically taken as a stepper motor 20. When the clamping member 50 moves to the initial position, the controller controls the step count of the motor 20 to reset to 0 and controls the motor 20 to stop moving, and the clamping member 50 remains in the initial position. When used for scanning the container 60, since the motor 20 has been reset to 0, the motor 20 operates according to the preset number of steps under the control of the controller, thereby accurately adjusting and controlling the pressing position of the clamping member 50. In addition, the controller can calculate the pressing position of the clamping member 50 based on the running step count of the motor 20. Then, during the process of the clamping member 50 and the container 60 being combined and driving the container 60 to rotate, the controller synchronously controls the barcode scanner to work, and the barcode scanner accordingly acquires and identifies the code on the side wall of the container 60.

[0056] For example, the position detection component 95 includes a reset optocoupler 951 and a stop 952 that cooperates with and can be detected by the reset optocoupler 951. One of the reset optocoupler 951 and the stop 952 is disposed on the fixed base 10, and the other is disposed on the motor 20.

[0057] Optionally, the stop 952 may include, but is not limited to, a baffle, a plate, or a strip.

[0058] For example, the stop 952 is specifically mounted on the mounting bracket 91, and the reset optocoupler 951 is mounted on the fixed base 10. Thus, when the motor 20 is working, the motor 20 and the mounting bracket 91 slide along the guide rail 70, and the stop 952 moves synchronously along the guide rail 70 under the drive of the mounting bracket 91. When the stop 952 moves to the reset optocoupler 951, it can be sensed by the reset optocoupler 951, thereby the controller controls the motor 20 to stop operating and reset the motor 20.

[0059] Another embodiment of this application provides a medical testing instrument, including the barcode scanning device of any of the above embodiments.

[0060] In use, the aforementioned medical testing instrument is operated by a motor 20 that drives a linkage shaft 30 to rotate. Since the linkage shaft 30 passes through a screw hole, its rotation causes the motor 20 to slide along the fixed base 10 and the clamping member 50 to move towards the container 60. The clamping member 50 is then fitted onto the top of the container 60 via a recess 51. As the clamping member 50 continues to rotate, it correspondingly drives the container 60 to rotate, allowing the scanning process to be completed. Simultaneously, the elastic component 40 connecting the clamping member 50 and the linkage shaft 30 buffers the axial movement of the linkage shaft 30, thereby reducing the clamping force exerted by the clamping member 50 on the top of the container 60 and preventing damage to the container 60. Therefore, on the one hand, the clamping member 50 and the top of the container 60 are clamped together to drive the container 60 to rotate. Compared with the method of contacting the side of the container 60 and driving the container 60 to rotate, there will be no slippage, which can improve the accuracy of rotation scanning. Moreover, the motor 20 is located above the container 60, and the structure is compact. On the other hand, a single motor 20 and linkage shaft 30 can complete the movement and drive the container 60 to rotate in the direction close to the top of the container 60. Furthermore, the elastic component 40 makes the clamping member 50 adaptive when it contacts the top of the container 60. It can eliminate the need for at least two sensors, making the structure compact and simple, reducing costs, and suitable for rotating containers 60 of various heights.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0064] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
