Description

Sample tube processing module, sample detection device and production line Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a sample tube processing module, a sample testing device, and a production line. Background Technology

[0002] Biological sample analysis has become an indispensable auxiliary detection technique in etiological analysis. Typically, collected biological samples are contained in sample tubes, and then the samples contained within the tubes are analyzed.

[0003] Samples are typically analyzed automatically using sample detection devices. Before automated detection, sample tubes need to be loaded onto the device. Currently, there are two loading methods: manual and automated. Manual loading requires manually sorting and classifying sample tubes of different sizes containing the samples to be tested and placing them on sample racks or trays. Due to the limited speed of manual loading and the need for a large number of racks or trays, the cost of the sample detection device is high, and the detection efficiency is low. Automated loading typically involves mixing multiple sample tubes together and loading them one by one. Since the sample tubes are of different sizes, they also need to be automatically sorted and classified. However, existing automated sorting structures are complex, resulting in low stability and affecting sorting efficiency. Therefore, the current sample tube sorting and separation efficiency needs improvement. Summary of the Invention

[0004] The main objective of this application is to provide a sample tube processing module, a sample detection device, and a production line to solve the problem of low efficiency in screening and separating sample tubes of different specifications in the prior art.

[0007] A supply unit is used to automatically supply sample tubes one by one to the first channel. The sample tubes entering the first channel move towards the second channel along the first straight line direction based on their own gravity and / or external force.

[0008] When the maximum diameter of the sample tube entering the first channel is greater than the first width and the minimum diameter is less than the first width, the sample tube is suspended in the first screening area.

[0019] Furthermore, the distance between the two first baffles towards the first screening area gradually decreases;

[0020] The distance between the two second baffles and the second screening area gradually decreases.

[0021] Furthermore, the second segment is provided with two first interceptors, which are arranged opposite to each other along the second straight line direction and are integrally formed with the second segment to cooperate with the second segment in defining the first blocking area; or the two first interceptors are respectively connected to the second segment to cooperate with the second segment in defining the first blocking area.

[0028] Furthermore, the loading station is located in the first straight line direction. The transfer unit includes a transfer component, a first transfer drive, and a second transfer drive. The first transfer drive is used to drive the transfer component to move along the first straight line direction between the first blocking area, the second blocking area, and the loading station. The second transfer drive is used to drive the transfer component to move vertically in the first blocking area, the second blocking area, and the loading station, respectively. The transfer component is used to pick up a sample tube in the first blocking area or the second blocking area and place the picked-up sample tube in the loading station.

[0029] Alternatively, if the loading station is not in the first straight line direction, the transfer unit includes a transfer component, a first transfer drive, a second transfer drive, and a third transfer drive. The first and third transfer drives are used to drive the transfer component to move between the first blocking area, the second blocking area, and the loading station.

[0030] Furthermore, the pushing and driving component is an electric push rod or a pneumatic push rod, which is used to drive the sample tube that has entered the first channel to move towards the second channel along the first straight line direction;

[0031] Alternatively, the push-drive assembly includes a push-drive component, a first transmission component, and a push component. The first transmission component is disposed at the output end of the push-drive component, and the push component is disposed on the first transmission component.

[0032] Furthermore, the first channel has a first center line along the first straight line direction, and the second channel has a second center line along the first straight line direction, with the second center line and the first center line located on the same straight line.

[0033] Furthermore, the sample tube processing module also includes a recycling unit;

[0034] The screening unit is also configured to have a third channel, which is disposed along the first straight line direction at the end of the second channel away from the first channel;

[0035] When the minimum diameter of the sample tube entering the first channel is greater than the second width, the sample tube moves from the first channel through the second channel to the third channel and falls from the third channel to the recycling unit.

[0036] Furthermore, the sample tube processing module also includes a recycling unit;

[0037] When the maximum diameter of the sample tube entering the first channel is less than the first width, the sample tube falls from the first screening area to the recycling unit;

[0038] When the maximum diameter of the sample tube entering the first channel is less than the second width and the minimum diameter is greater than the first width, the sample tube moves from the first channel to the second channel and falls from the second screening area to the recycling unit.

[0039] Furthermore, the supply unit includes a dispensing compartment for receiving mixed sample tubes; and

[0040] A transfer component is used to transfer the sample tubes in the delivery chamber one by one to the first channel.

[0041] Furthermore, the transfer assembly includes a transfer drive, a second transmission component, and a plurality of pick-up components, wherein the plurality of pick-up components are respectively disposed on the second transmission component;

[0042] Each of the aforementioned pick-up components has a pick-up position and a discharge position, wherein the pick-up position is located at the bottom of the discharge bin and the discharge position is located above the first channel;

[0043] Driven by the transfer drive, the second transmission member drives multiple picking members to move in a cycle, so that each picking member picks up a sample tube at the picking position and places the picked sample tube into the first channel at the discharging position.

[0044] Furthermore, the direction of the first straight line is horizontal;

[0045] The lifting member includes a connecting part and a lifting part. The connecting part is connected to the second transmission member, and the lifting part extends out of the second transmission member along the first straight direction. The side of the lifting part near the second transmission member has a relief groove.

[0046] The supply unit further includes a first rejecting member, which is disposed on the movement path of the picking member from the picking position to the discharging position. When the picking member passes the first rejecting member, the first rejecting member passes through the clearance groove to reject the sample tube that is far away from the first rejecting member among the two sample tubes arranged along the first straight line direction.

[0047] And / or, the supply unit further includes a second rejecting member, a rotating member, and a retaining member. The second rejecting member is disposed on the rotating member, and the retaining member is used to drive the rotating member and the second rejecting member to remain on the movement path of the pick-up member from the material pick-up position to the material dispensing position. When the pick-up member passes the second rejecting member, the second rejecting member will reject the sample tube stacked above the sample tube at the bottom of the corresponding pick-up member.

[0048] Furthermore, the delivery chamber includes a limiting baffle and multiple flow guide baffles, the limiting baffle and the multiple flow guide baffles enclose and define the delivery chamber, and the lifting part of the lifting member moves against the limiting baffle within the delivery chamber;

[0049] The supply unit also includes a limiting component, and the side of the connecting part of the lifting member away from the limiting baffle moves against the limiting component;

[0050] The limiting component has a notch in the vertical direction. The second rejecting component, the rotating component, and the holding component are located at the notch. The limiting baffle has a flow guide groove. The sample tubes stacked above the sample tubes at the bottom of the receiving component are rejected by the second rejecting component and then returned to the delivery chamber under the guidance of the flow guide groove.

[0051] Furthermore, the limiting component includes a first limiting member and a second limiting member, the first limiting member being disposed above the second limiting member, and the first limiting member and the second limiting member being spaced apart to define the notch;

[0052] The side of the second limiting member closest to the limiting baffle gradually moves towards the limiting baffle in a vertically upward direction to form a limiting guide surface;

[0053] The rotating component includes a second abutting surface, which is obliquely downward toward the limiting baffle.

[0054] The retaining member is used to drive the rotating member to move toward the limiting baffle, and as the picking member moves vertically upward with the second transmission member, the second abutting surface abuts against the connecting part of the picking member that gradually approaches the second rejecting member, so that the second rejecting member rejects the sample tubes stacked on the picking member.

[0055] Furthermore, the length of the rotating member in the vertical direction is greater than the distance between two adjacent lifting members, and the rotating member also includes a first abutting surface, which is located above the second abutting surface and faces the limiting baffle obliquely upward.

[0056] The retaining member is used to drive the rotating member to move toward the limiting baffle, and during the process of the lifting member moving vertically upward with the second transmission member, the first abutting surface and / or the second abutting surface abut against the connecting portion of each of the two adjacent lifting members, so that the rotating member abuts against the connecting portion of at least one of the lifting members.

The first width of the first screening area is set to be smaller than the second width of the second screening area along the second straight line direction which is in the same plane as the first straight line direction and perpendicular to it. This allows the first screening area and the second screening area to screen sample tubes of different specifications. After the supply unit automatically supplies sample tubes one by one to the first channel, the sample tubes entering the first channel will move towards the second channel along the first straight line direction based on their own gravity and / or external force. During the movement, they will adaptively hang in the first screening area or the second screening area according to their own specifications, thereby automatically completing the screening process of sample tubes of different specifications. Based on the simple structure of the screening unit, efficient and stable screening of sample tubes of different specifications is achieved. Attached Figure Description

Detailed Implementation

[0079] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0080] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0081] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0082] Please refer to Figure 1. In the field of biosample testing, sample tubes (300) are typically used to collect biological samples (such as blood, urine, cerebrospinal fluid, etc.) from patients. These samples are then sent for analysis to determine the levels of various indicators. The results are used to assess the patient's physical condition, identify the cause of illness, or determine whether the patient is suitable for surgery. This method has become a very common choice for doctors in the diagnosis and treatment process. Therefore, sample testing departments process a large number of samples every day, and because the sample requirements for different tests are usually different, different sizes of sample tubes (300) are typically used for different tests.

[0083] A sample tube 300 typically consists of two parts: a cap 310 and a body 320. The body 320 is used to hold the sample, and the cap 310 seals the opening of the body 320 to prevent sample leakage. Commonly used sample tubes 300 are generally divided into two categories based on the diameters of the cap 310 and the body 320: the first category has a cap 310 diameter equal to the body 320 diameter, and the second category has a cap 310 diameter larger than the body 320 diameter. For the second category, the difference in diameter between the cap 310 and the body 320 allows for the selection of sample tubes 300 with different body 320 diameters using screening channels of varying widths.

[0084] It should be noted that the tube body 320 is not a regular cylinder. Usually, the bottom of the sample tube 300 is spherical or conical. Therefore, the diameter of the tube body 320 referred to in this application does not include the bottom part of the sample tube 300.

[0085] Because of the large number of samples that need to be tested, the sample collection department usually keeps the sample tubes 300 together after collection. This allows for the quick placement of the sample tubes 300 containing samples into a transfer container, and also allows the transfer container to hold more sample tubes 300 at once, thus enabling the transfer of a larger number of sample tubes 300 at once. However, since sample tubes 300 of different specifications are mixed together, how to efficiently and quickly screen and separate the sample tubes 300 of different specifications has become an urgent problem for the sample testing department.

[0086] To address this issue, please refer to Figures 2-3. This application provides a sample tube processing module 100. The sample tube processing module 100 includes a mounting frame 60, and a screening unit 10 and a supply unit 20 respectively disposed on the mounting frame 60. The supply unit 20 is used to supply sample tubes 300 to the screening unit 10, and the screening unit 10 is used to screen the received sample tubes 300 to classify sample tubes 300 of different specifications.

[0087] Please refer to Figures 4-7. The screening unit 10 has a first channel 114 and a second channel 116 that are interconnected along a first straight line direction L1. The supply unit 20 is used to automatically supply sample tubes 300 one by one to the first channel 114, thereby realizing the automatic supply of sample tubes 300. The sample tubes 300 entering the first channel 114 will move along the first straight line direction L1 to the second channel 116 under the action of their own gravity and / or external forces, and the screening is completed during the movement within the first channel 114 or the second channel 116.

[0088] As shown in Figures 4-5, a first screening area 1141 is formed at the bottom of the first channel 114 along the first straight direction L1, and the first screening area 1141 has a first width along the second straight direction L2; a second screening area 1161 is formed at the bottom of the second channel 116 along the first straight direction L1, and the second screening area 1161 has a second width along the second straight direction L2; the first width is smaller than the second width, and the first straight direction L1 and the second straight direction L2 are located in the same plane and are perpendicular to each other, so the first screening area 1141 and the second screening area 1161 can screen sample tubes 300 of different specifications.

[0089] When the maximum diameter of the sample tube 300 entering the first channel 114 is greater than the first width and the minimum diameter is less than the first width, the sample tube 300 is suspended in the first screening area 1141, thereby screening out the sample tube 300. In this embodiment, the maximum diameter of the sample tube 300 is the diameter of the cap 310, and the minimum diameter of the sample tube 300 is the diameter of its body 320. Since there is a difference in diameter between the cap 310 and the body 320, a stepped surface is formed between the side of the cap 310 facing the body 320 and the outer wall of the body 320. For the case where the diameter of the cap 310 is greater than the first width and the diameter of the body 320 is less than the first width, the sample will be suspended in the first screening area 1141 through the stepped surface.

[0090] Referring to Figure 7, when the maximum diameter of the sample tube 300 entering the first channel 114 is greater than the second width, and the minimum diameter is less than the second width but greater than the first width, the sample tube 300 will not be suspended in the first screening area 1141 by its own gravity. Therefore, the sample tube 300 will continue to move towards the second channel 116 and be suspended in the second screening area 1161. It can be understood that the reason why the sample tube 300 is suspended in the first screening area 1141 and in the second screening area 1161 is the same, both determined by the size relationship between the tube body 320, the tube cap 310, and the first or second width.

[0091] Therefore, in the sample tube processing module 100 of this application, by setting the screening unit 10 to form a first channel 114 and a second channel 116 interconnected along the first straight direction L1, and forming a first screening area 1141 at the bottom of the first channel 114 along the first straight direction L1, and forming a second screening area 1161 at the bottom of the second channel 116 along the first straight direction L1, and setting the first width of the first screening area 1141 to be smaller than the second width of the second screening area 1161 along the second straight direction L2 which is in the same plane as and perpendicular to the first straight direction L1, the first width of the first screening area 1141 is made to be smaller than the second width of the second screening area 1161. The first and second screening areas 1161 can screen sample tubes 300 of different specifications. After the supply unit 20 automatically supplies sample tubes 300 one by one to the first channel 114, the sample tubes 300 entering the first channel 114 will move towards the second channel 116 along the first straight direction L1 based on their own gravity and / or external force. During the movement, they will adaptively suspend themselves in the first screening area 1141 or the second screening area 1161 according to their own specifications, thereby automatically completing the screening process of sample tubes 300 of different specifications. Based on the simple structure of the screening unit 10, efficient and stable screening of sample tubes 300 of different specifications is achieved.

[0092] In some embodiments, as shown in FIG5, the first linear direction L1 and the second linear direction L2 are perpendicular to each other in the same horizontal plane. Therefore, the sample tube 300 entering the first channel 114 cannot move from the first channel 114 to the second channel 116 by its own gravity.

[0093] In order to enable the sample tube 300 to move from the first channel 114 to the second channel 116, the screening unit 10 includes a push-drive component, which is used to drive the sample tube 300 located in the first channel 114 to move to the second channel 116, so that the sample tube 300 driven by the push-drive component can move from the first channel 114 to the second channel 116.

[0094] In some embodiments, the first linear direction L1 and the second linear direction L2 are perpendicular to each other in the same inclined plane, so that the first channel 114 and the second channel 116 are in an inclined state, and the sample tube 300 entering the first channel 114 can move from the first channel 114 to the second channel 116 based on its own gravity. Therefore, the overall structure of the screening unit 10 can be further simplified, avoiding the need to set up a drive component to drive the sample tube 300 to move from the first channel 114 to the second channel 116.

[0095] In some embodiments, as shown in Figures 4-7, the screening unit 10 includes a push-drive component for driving a sample tube 300 located in the first channel 114 to move towards the second channel 116. Furthermore, the first linear direction L1 and the second linear direction L2 are perpendicular to each other within the same inclined plane, such that the first channel 114 and the second channel 116 are in an inclined state, and the sample tube 300 entering the first channel 114 is also in an inclined state, thereby enabling the sample tube 300 entering the first channel 114 to move more smoothly towards the second channel 116.

[0096] The first channel 114 is also configured with a first blocking area 115, which is disposed between the first screening area 1141 and the second screening area 1161 along the first straight line direction L1. When the sample tube 300 entering the first channel 114 switches to a suspended state in the first screening area 1141, the sample tube 300 will continue to move towards the first blocking area 115 under its own gravity and / or the drive of the push drive component, until it is intercepted and stopped in the first blocking area 115. This prevents the sample tube 300 from continuing to move to the second channel 116 and falling from the second screening area 1161, and also achieves the positioning of the sample tube 300, so that the transfer unit 30 can easily transfer the sample tube 300 screened by the first screening area 1141 away in the first blocking area 115.

[0097] The second channel 116 is also configured to form a second blocking area 118, which is located along the first straight line direction L1 on the side of the second screening area 1161 away from the first blocking area 115. When the sample tube 300 moving from the first channel 114 to the second channel 116 switches to a suspended state in the second screening area 1161, the sample tube 300 will continue to move towards the second blocking area 118 under its own gravity and / or the drive of the push drive component, until it is intercepted and stopped in the second blocking area 118. This prevents the sample tube 300 from continuing to move and achieves the positioning of the sample tube 300, so that the transfer unit 30 can easily transfer the sample tube 300 screened by the second screening area 1161 away in the second blocking area 118.

[0098] Please refer to Figures 4-7. The filtering unit 10 also includes a channel component, which is configured to form the first channel 114 and the second channel 116. The drive component is disposed on the channel component.

[0099] The channel assembly includes a base frame 111, a first baffle 1121, a second baffle 1122, a first interceptor 1131, and a second interceptor 1132. The base frame 111 includes a first segment 1111, a second segment 1112, a third segment 1113, and a fourth segment 1114 connected in sequence along the first straight direction L1.

[0100] The two first baffles 1121 extend along the first straight direction L1 and are respectively disposed opposite to each other along the second straight direction L2 in the first segment 1111, and together with the first segment 1111, they form the first channel 114; wherein, the first segment 1111 defines the first screening area 1141.

[0101] The distance between the two first baffles 1121 towards the first screening area 1141 gradually decreases, that is, the width of the opening end of the first channel 114 towards the first screening area 1141 along the second straight direction L2 gradually decreases, so that the sample tube 300 entering the first channel 114 can move towards the first screening area 1141 under the guidance of the two first baffles 1121, thereby preventing the sample tube 300 from falling out of the first channel 114; wherein, the first guiding surface of the two first baffles 1121 facing each other along the second straight direction L2 can be an inclined surface or a curved surface. No specific limitation is made here.

[0102] At least one of the first interceptors 1131 is disposed in the second segment 1112 and together with the second segment 1112 forms the first blocking area 115; wherein, the first blocking area 115 is only used to intercept the sample tube 300 suspended in the first screening area 1141. For the sample tube 300 that has not switched to the suspended state in the first screening area 1141, it will move from the first channel 114 across the first blocking area 115 to the second channel 116 based on its own gravity and / or the drive of the push drive component.

[0103] In some embodiments, the second segment 1112 is provided with two first interceptors 1131. The two first interceptors 1131 are arranged opposite to each other along the second straight direction L2 and spaced apart by a first distance. The first distance is less than the diameter of the tube body 320 of the sample tube 300 suspended in the first screening area 1141, so as to cooperate with the second segment 1112 to define and form the first blocking area 115, and to intercept the sample tubes 300 screened by the first screening area 1141. The two first interceptors 1131 are integrally formed with the second segment 1112, thereby simplifying the assembly of the channel assembly and improving assembly efficiency; or, the two first interceptors 1131 are detachably connected to the second segment 1112 to cooperate with the second segment 1112 to define and form the first blocking area 115, so that the first interceptors 1131 can be adaptively replaced according to the diameter of the tube body 320 of the sample tube 300 suspended in the first screening area 1141, in order to intercept sample tubes 300 with smaller tube body 320 diameters.

[0104] Please refer to Figure 6. The screening unit 10 further includes a first detection element 13, which is located in the second segment 1112 and is used to detect whether a sample tube 300 is suspended in the first blocking area 115. When the first detection element 13 detects that a sample tube 300 is suspended in the blocking area, the first detection element 13 will send a first signal to the host computer. After receiving the first signal, the host computer controls the transfer unit 30 to move the sample tube 300 located in the first blocking area 115 away, so that the host computer can control the push drive component to reset and control the supply unit 20 to continue to deliver the sample tube 300 to the first channel 114.

[0105] The two second baffles 1122 extend along the first straight direction L1 and are respectively disposed opposite to the third segment 1113 along the second straight direction L2, and together with the third segment 1113, form the second channel 116; wherein the third segment 1113 defines the second screening area 1161.

[0106] The distance between the two second baffles 1122 and the second screening area 1161 gradually decreases, that is, the width of the opening end of the second channel 116 towards the second screening area 1161 along the second straight direction L2 gradually decreases, so that the sample tube 300 entering the second channel 116 can move towards the second screening area 1161 under the guidance of the two second baffles 1122, thereby preventing the sample tube 300 from falling out of the second channel 116; wherein, the second guiding surface of the two second baffles 1122 facing each other along the second straight direction L2 can be an inclined surface or a curved surface. No specific limitation is made here.

[0107] At least one second interceptor 1132 is disposed on the fourth segment 1114 and together with the fourth segment 1114 forms the second blocking area 118; wherein, the second blocking area 118 is only used to intercept the sample tube 300 suspended in the second screening area 1161. For the sample tube 300 that has not switched to the suspended state in the second screening area 1161, it will pass through the second blocking area 118 and continue to move backward based on its own gravity and / or the drive of the push drive component.

[0108] In some embodiments, the fourth segment 1114 is provided with two second interceptors 1132. The two second interceptors 1132 are arranged opposite to each other along the second straight direction L2 and spaced apart by a second distance. The second distance is smaller than the diameter of the tube body 320 of the sample tube 300 suspended in the second screening area 1161, so as to cooperate with the fourth segment 1114 to define and form the second blocking area 118, and to intercept the sample tube 300 screened by the second screening area 1161. The two second interceptors 1132 are integrally formed with the fourth segment 1114, thereby simplifying the assembly of the channel assembly and improving the assembly efficiency. Alternatively, the two second interceptors 1132 are detachably connected to the fourth segment 1114 to cooperate with the fourth segment 1114 to define and form the second blocking area 118, so that the second interceptors 1132 can be adaptively replaced according to the diameter of the tube body 320 of the sample tube 300 suspended in the second screening area 1161, so as to intercept sample tubes 300 with smaller tube body 320 diameters.

[0109] Please refer to Figure 6. The screening unit 10 also includes a second detection element 14, which is located in the fourth segment 1114 and is used to detect whether a sample tube 300 is suspended in the second blocking area 118. When the second detection element 14 detects that a sample tube 300 is suspended in the second blocking area, the second detection element 14 will send a second signal to the host computer. After receiving the second signal, the host computer controls the transfer unit 30 to move the sample tube 300 located in the second blocking area 118 away, so that the host computer can control the push drive component to reset and control the supply unit 20 to continue to deliver the sample tube 300 to the first channel 114.

[0110] The transfer unit 30 is used to transfer the sample tube 300 suspended in the first blocking area 115 or the second blocking area 118 to the loading station, so that the first blocking area 115 can intercept the next sample tube 300 that has switched to the suspended state in the first screening area 1141, and the second blocking area 118 can intercept the next sample tube 300 that has switched to the suspended state in the second screening area 1161.

[0111] In some embodiments, the first detection element 13 is also used to cooperate with the transfer unit 30 to detect the height of the sample tube 300 suspended in the first blocking area 115, so that the first detection element 13 can detect whether there is a suspended sample tube 300 in the first blocking area 115, and can also cooperate with the transfer unit 30 to detect the height of the sample tube 300 intercepted in the first blocking area 115, thereby making the first detection element 13 multifunctional.

[0112] The sample tube 300 suspended in the first blocking area 115 has a fixed height in the vertical direction above the detection position of the first detection element 13. The host computer can obtain the time taken by the transfer unit 30 to lift the sample tube 300 located in the first blocking area 115 from the time the transfer unit 30 starts to lift the sample tube 300 vertically upward until the first detection element 13 stops detecting the sample tube 300. The host computer can also calculate the height of the sample tube 300 based on the speed at which the transfer unit 30 lifts the sample tube 300 and the aforementioned fixed height.

[0113] The height of the sample tube 300 suspended in the first blocking area 115 is detected by the first detection element 13 in conjunction with the transfer unit 30. Therefore, when the sample tube 300 is transferred to the loading station, the host computer can control the transfer unit 30 to move downward a suitable distance from its initial position above the loading station and reach the loading position according to the height of the sample tube 300, so as to accurately load the sample tube 300 to the loading station. This allows the transfer unit 30 to be compatible with the transfer of sample tubes 300 of different heights to the loading station with the cooperation of the first detection element 13.

[0114] The initial position is the position where the transfer unit 30 moves along the plane of the first straight line L1 to the position directly above the loading station. The loading position is the position where the transfer unit moves vertically downwards a certain distance from the initial position to load the sample tube 300 to the loading station. Therefore, the initial position, the loading position, and the loading station are on the same straight line in the vertical direction, and the loading position is located between the processing station and the initial position in the vertical direction. The transfer unit acts on the cap 310 of the sample tube 300 to transfer the sample tube 300. The sample tube 300 transferred to the loading station is loaded through the part of the tube body 320 near the bottom of the tube.

[0115] It is understood that the vertical distance from the loading station to the initial position is fixed, but the loading position of the transfer unit 30 is different for sample tubes 300 of different heights being screened in the first screening area 1141. For sample tubes 300 with higher height, the loading position of the transfer unit 30 is higher, and therefore the distance the transfer unit 30 moves from the initial position to the loading position is shorter; conversely, for sample tubes 300 with lower height, the loading position of the transfer unit 30 is lower, and therefore the distance the transfer unit 30 moves from the initial position to the loading position is longer.

[0116] In some embodiments, the second detection element 14 is also used to cooperate with the transfer unit 30 to detect the height of the sample tube 300 suspended in the second blocking area 118, so that the second detection element 14 can detect whether there is a suspended sample tube 300 in the second blocking area 118, and can also cooperate with the transfer unit 30 to detect the height of the sample tube 300 intercepted in the second blocking area 118, thereby making the second detection element 14 multifunctional.

[0117] The sample tube 300 suspended in the second blocking area 118 has a fixed height in the vertical direction above the detection position of the second detection element 14. The host computer can obtain the time taken by the transfer unit 30 to lift the sample tube 300 located in the second blocking area 118 from the time the transfer unit 30 starts to lift the sample tube 300 vertically upward until the second detection element 14 stops detecting the sample tube 300. The host computer can also calculate the height of the sample tube 300 based on the speed at which the transfer unit 30 lifts the sample tube 300 and the aforementioned fixed height.

[0118] The height of the sample tube 300 suspended in the second blocking area 118 is detected by the second detection element 14 in conjunction with the transfer unit 30. Thus, when the sample tube 300 is transferred to the loading station, the host computer can control the transfer unit 30 to move downward a suitable distance from its initial position above the loading station and reach the loading position according to the height of the sample tube 300, so as to accurately load the sample tube 300 to the loading station. This allows the transfer unit 30 to be compatible with the transfer of sample tubes 300 of different heights to the loading station with the cooperation of the second detection element 14.

[0119] In some embodiments, the sample tube processing module 100 includes a separate height detection unit 40. The height detection unit 40 is used to capture images of the sample tubes 300 selected in the first screening area 1141 or the second screening area 1161, and send the captured images to the host computer. The host computer receives the images to obtain the height of the sample tube 300 corresponding to the image, and controls the transfer unit 30 to move the sample tube 300 vertically downward from the initial position a corresponding distance to the corresponding loading position according to the height of the sample tube 300, so as to accurately load the sample tube 300 to the loading station, so that the transfer unit 30 can be compatible with the transfer of sample tubes 300 of different heights to the loading station with the cooperation of the height detection unit 40.

[0120] The height detection unit 40 may be a camera or other image acquisition device that can capture images of the sample tube 300 transferred by the transfer unit 30.

[0121] In some embodiments, as shown in Figures 3 and 14, the height detection unit 40 includes a transmitter 41 and a receiver 42. The transmitter 41 and the receiver 42 are located on opposite sides of the loading station, and the receiver 42 is used to receive the detection light emitted by the transmitter 41. When the transfer unit 30 moves the selected sample tube 300 from the initial position to the loading position, the bottom of the sample tube 300 will preferentially enter the detection area formed between the transmitter 41 and the receiver 42. Since the distance from the bottom of each sample tube 300 to the loading station is the same when the bottom of each sample tube 300 triggers the detection area, the host computer only needs to control the transfer unit 30 to continue descending vertically by a fixed height to accurately load the corresponding sample tube 300 to the loading station. This allows the transfer unit 30, with the cooperation of the height detection unit 40, to accommodate the transfer of sample tubes 300 of different heights to the loading station.

[0122] When a sample tube 300 is loaded at the loading station, part of the detection light emitted by the transmitter 41 will be blocked by the sample tube 300, so that the receiver 42 can only receive the detection light that is not blocked by the sample tube 300. Thus, the height of the sample tube 300 at the loading station can be obtained based on the detection light actually received by the receiver 42.

[0123] In some embodiments, as shown in Figures 4-7, the base frame 111 is integrally formed so that the first segment 1111, the second segment 1112, the third segment 1113 and the fourth segment 1114 are an integral structure, thereby giving the base frame 111 better structural strength and stability, and simplifying the assembly steps of the channel assembly.

[0124] It is understood that the first interceptor 1131 and the second interceptor 1132 may also be integrally formed with the base frame 111 to form an integral structure, thereby simplifying the assembly steps of the channel assembly.

[0125] In some embodiments, the base frame 111 can be divided into a first frame and a second frame on opposite sides along the first straight direction L1. The distance between the first frame and the second frame can be adjusted along the second straight direction L2, thereby making the first distance of the first screening area 1141 along the second straight direction L2 adjustable, and the second width of the second screening area 1161 along the second straight direction L2 adjustable. This allows for adaptive adjustment of the distance between the first frame and the second frame along the second straight direction L2 according to the specifications of the sample tube 300 to be screened.

[0126] In some embodiments, the loading station is located on the first linear direction L1, such that the first blocking area 115, the second blocking area 118, and the loading station are all located on the first linear direction L1. Therefore, the transfer unit 30 can transfer the sample tube 300 located in the first blocking area 115 or the second blocking area 118 to the loading station by moving in a two-dimensional linear motion along the first linear direction L1 and the vertical direction.

[0127] In this embodiment, as shown in Figures 2-3 and 8, the transfer unit 30 includes a transfer component 31, a first transfer drive 32, and a second transfer drive 33. The first transfer drive 32 drives the transfer component 31 to move along the first straight line L1 between the first blocking area 115, the second blocking area 118, and the loading station, so that the transfer component 31 can move above the first blocking area 115, the second blocking area 118, and the loading station under the drive of the first transfer drive 32. The second transfer drive 33 drives the transfer component 31 to move vertically between the first blocking area 115, the second blocking area 118, and the loading station, so that the transfer component 31 can pick up the screened sample tubes 300 in the first blocking area 115 or the second blocking area 118 and place the picked-up sample tubes 300 in the loading station, thereby realizing the transfer of the screened sample tubes 300.

[0128] By setting the loading station on the first straight direction L1, the overall structure of the transfer unit 30 can be effectively simplified, so as to control the production cost of the transfer unit 30 and simplify the control program of the transfer unit 30.

[0129] In some embodiments, the loading station is not on the first straight direction L1, that is, the loading station is not on the same straight line as the first blocking area 115 and the second blocking area 118. Therefore, the transfer unit 30 needs to perform three-dimensional linear motion in two different straight directions and one vertical direction in the same plane to transfer the sample tube 300 of the first blocking area 115 or the second blocking area 118 to the loading station.

[0130] In this embodiment, as shown in Figure 8, the transfer unit 30 includes a transfer component 31, a first transfer drive 32, a second transfer drive 33, and a third transfer drive 34. The first transfer drive 32 and the third transfer drive 34 are used to drive the transfer component 31 to move between the first blocking area 115, the second blocking area 118, and the loading station. The second transfer drive 33 is used to drive the transfer component 31 to move vertically in the first blocking area 115, the second blocking area 118, and the loading station, respectively. The transfer component 31 is used to pick up the sample tube 300 in the first blocking area 115 or the second blocking area 118 and place the picked-up sample in the loading station.

[0131] The first transfer drive 32 and the third transfer drive 34 are respectively used to drive the transfer assembly 31 to move in different linear directions within the same plane. In a specific embodiment, the first transfer drive 32 can drive the transfer assembly 31 to move along the first linear direction L1, and the third transfer drive 34 can drive the transfer assembly 31 to move along the second linear direction L2, so that the linear directions in which the first transfer drive 32 and the third transfer drive 34 drive the transfer assembly 31 to move are perpendicular to each other within the same plane.

[0132] It is understood that, in some embodiments, the linear directions in which the first transfer drive 32 and the third transfer drive 34 each drive the transfer component 31 to move may be intersecting and not perpendicular to each other in the same plane.

[0133] In this embodiment, by setting the first transfer drive 32, the second transfer drive 33 and the third transfer drive 34 to drive the transfer assembly 31 to perform three-dimensional motion to transfer the sample tube 300 of the first blocking area 115 or the second blocking area 118 to the loading station, the requirements for the location of the loading station can be reduced, so that the transfer unit 30 can accurately transfer the sample tube 300 of the first blocking area 115 or the second blocking area 118 to the loading station.

[0134] Please refer to Figure 8 again. The transfer assembly 31 includes a first clamping arm 311, a second clamping arm 312, and a clamping drive 313. The clamping drive 313 is used to drive at least one of the first clamping arm 311 and the second clamping arm 312 to move closer to or further away from the other, so that the first clamping arm 311 and the second clamping arm 312 can clamp the screened sample tube 300 in the first blocking area 115 or the second blocking area 118 under the drive of the clamping drive 313, and release the clamped sample tube 300 at the loading station.

[0135] Please refer to Figures 4-7. The screening unit 10 further includes a third detection element 15, which is disposed on the base frame 111. The supply unit 20 includes a pick-up element 223, which has a material dispensing position. The pick-up element 223 is used to dispense a sample tube 300 into the first channel 114 at the material dispensing position.

[0136] In some embodiments, the third detection element 15 is used to detect whether a sample tube 300 is being held on the pick-up member 223 near the discharge position. If a sample tube 300 is detected being held on the pick-up member 223 near the discharge position, the third detection element 15 will send a third signal to the host computer. After the pick-up member 223 places the sample tube into the pair channel 114, the host computer will control the push drive component to push the sample tube 300 located in the first channel to move along the first straight direction L1 to the second channel 116 according to the third signal.

[0137] In some embodiments, the third detection element 15 may also be used to detect whether there is a sample tube 300 in the first channel 114. When the third detection element 15 detects that there is a sample tube 300 in the first channel 114, the third detection element 15 will feed back a third signal to the host computer, and the host computer will control the push drive component to push the sample tube 300 located in the first channel 114 to move along the first straight direction L1 to the second channel 116 according to the third signal.

[0138] When the third detection element 15 is configured to directly detect whether there is a sample tube 300 in the first channel, for a sample tube 300 that enters the first channel 114 and falls directly from the first screening area 1141, the third detection element 15 will not detect the sample tube 300 that falls directly from the first screening area 1141. Alternatively, if the third detection element fails to continuously detect the sample tube 300 that falls directly from the first screening area 1141 within the preset detection time period, the third detection element 15 will not feed back the third signal to the host computer. Therefore, the host computer will not control the push drive component to perform the operation of pushing the sample tube 300 from the first channel 114 to the second channel 116, thereby effectively avoiding the push drive component from performing an invalid push operation.

[0139] When the sample tube 300 entering the first channel 114 switches to a suspended state in the first screening area 1141, the push drive component will push the sample tube 300 to the first blocking area 115, and the transfer unit 30 will transfer the sample tube 300 to the loading station in the first blocking area; when the sample tube 300 entering the first channel 114 switches to a suspended state in the second screening area 1161, the pusher 123 will continue to push the sample tube 300 to the second blocking area 118, and the transfer unit 30 will transfer the sample tube 300 to the loading station in the second blocking area 118.

[0140] In some embodiments, the push drive assembly is an electric push rod or a pneumatic push rod, which is mounted on the base frame 111 and includes a main body and a push part. The push part extends into the first channel 114 and, driven by the main body, can move along the first straight direction L1 from one end of the first channel 114 away from the second channel 116 to the second blocking area 118, so that the sample tube 300 suspended in the first screening area 1141 can be pushed to the first blocking area 115 and transferred to the loading station by the transfer unit 30, and the sample tube 300 suspended in the second screening area 1161 can be pushed to the second blocking area 118 and transferred to the loading station by the transfer unit 30.

[0141] By setting the electric push rod or the pneumatic push rod, the push drive assembly has the advantages of simple structure and integral structure, which makes it easy to quickly assemble the pneumatic push rod or the electric push rod onto the base frame 111.

[0142] In some embodiments, the drive assembly includes a drive member 121, a first transmission member 122, and a drive member 123. The first transmission member 122 is disposed at the output end of the drive member 121, and the drive member 123 is disposed on the first transmission member 122. The drive member 121 drives the first transmission member 122 to move along the first linear direction L1, thereby causing the drive member 123 to move synchronously, so that the drive member 123 drives the sample tube 300 entering the first channel 114 to move towards the second channel 116 along the first linear direction L1.

[0143] The driving component 121 can be a motor, the first rotating component 25 can be a transmission belt or a transmission chain, the pushing component 123 can be a pusher block, the pusher block is disposed on the transmission belt or the transmission chain, the base frame 111 is also provided with a driven wheel, the output end of the motor is provided with a driving wheel, and the transmission belt or the transmission chain is disposed between the driving wheel and the driven wheel. Under the drive of the motor, the pusher block can move along the first straight direction L1 from the end of the first channel 114 away from the second channel 116 to the second blocking area 118 via the transmission belt or the transmission chain, so that the sample tube 300 suspended in the first screening area 1141 can be pushed to the first blocking area 115 and transferred to the loading station by the transfer unit 30, and the sample tube 300 suspended in the second screening area 1161 can be pushed to the second blocking area 118 and transferred to the loading station by the transfer unit 30.

[0144] In some embodiments, as shown in FIG7, the push drive assembly further includes a guide member 126, which may be a guide rail or a guide rod. The guide member 126 is disposed on the base frame 111 along the first linear direction L1, and the push member 123 is slidably connected to the guide member 126. This allows the push drive member 121 to drive the push member 123 to move more stably along the first linear direction L1 towards the second channel 116 under the limiting and guiding effect of the guide member 126 during the movement of the push drive member 121 driven by the first transmission member 122.

[0145] In some embodiments, as shown in FIG5, the first channel 114 has a first centerline L3 along the first straight direction L1, and the second channel 116 has a second centerline L4 along the first straight direction L1, wherein the second centerline L4 and the first centerline L3 are located on the same straight line. Therefore, a sample tube 300 that enters the first channel 114 and has not switched to a suspended state within the first channel 114 will smoothly pass through the first blocking area 115 and enter the second channel 116, thereby effectively improving the smoothness and stability of the sample tube 300 moving from the first channel 114 to the second channel 116, so as to improve the screening efficiency of the sample tube 300.

[0146] In some embodiments, as shown in Figures 4-5, the screening unit 10 is further configured with a third channel 119, which is disposed along the first straight direction L1 at the end of the second channel 116 away from the first channel 114. Sample tubes 300 that are not switched to a suspended state within the second channel 116 will move to the third channel 119 under the drive of the push-drive assembly.

[0147] The base frame 111 may also include a fifth segment 1115, which is connected to the end of the fourth segment 1114 away from the third segment 1113, and the fifth segment 1115 defines the third channel 119.

[0148] Please refer to Figures 2 and 9. The sample tube processing module 100 also includes a recovery unit 50. The recovery unit 50 is disposed on the mounting bracket 60 and located below the screening unit 10. The recovery unit 50 is used to recover sample tubes 300 that have fallen from the first screening area 1141 or the second screening area 1161, as well as to recover sample tubes 300 that have entered the third channel 119.

[0149] When the maximum diameter of the sample tube 300 entering the first channel 114 is less than the first width, the sample tube 300 will fall from the first screening area 1141 to the recycling unit 50, thereby recycling the sample tube 300.

[0150] When the maximum diameter of the sample tube 300 entering the first channel 114 is less than the second width and the minimum diameter is greater than the first width, the sample tube 300 will move from the first channel 114 to the second channel 116 under the drive of the push drive component, and fall from the second screening area 1161 to the recycling unit 50, thereby recycling the sample tube 300.

[0151] When the minimum diameter of the sample tube 300 entering the first channel 114 is greater than the second width, the sample tube 300 moves from the first channel 114 through the second channel 116 to the third channel 119 under the drive of the push drive assembly, and falls from the third channel 119 to the recycling unit 50, thereby recycling the sample tube 300.

[0152] By setting up the recycling unit 50, sample tubes 300 that were not screened in the first screening area 1141 or the second screening area 1161 will be recycled by the recycling unit 50.

[0153] The recycling unit 50 includes a recycling channel 51 and a recycling container 52. The recycling channel 51 includes a converging part 511 and a receiving part 512. The converging part 511 is located below the channel assembly and can receive sample tubes 300 that fall from the first screening area 1141, the second screening area 1161, and the third channel 119. The receiving part 512 is connected to the converging part 511 and is located below the converging part 511. The recycling container 52 is located below the receiving part 512, so that the recycling container 52 can directly receive the fallen sample tubes 300. The recycling container 52 can be separated from the receiving part 512, so that after collecting a certain amount of sample tubes, the collected sample tubes 300 can be transferred away by pulling out or removing the recycling container 52, thereby improving the recycling efficiency of the screened sample tubes 300.

[0154] Please refer to Figures 10-13. The supply unit 20 includes a delivery compartment 21 and a transfer component 22. The delivery compartment 21 is used to receive mixed sample tubes 300, that is, medical personnel can put mixed sample tubes 300 to be screened into the delivery compartment 21 in batches, thereby improving the delivery efficiency of sample tubes 300. The transfer component 22 is used to transfer the sample tubes 300 in the delivery compartment 21 one by one to the first channel 114, so that the screening unit 10 can screen the received sample tubes 300 one by one.

[0155] The transfer assembly 22 includes a transfer drive 221, a second transmission component 222, and a plurality of the holding components 223. The plurality of holding components 223 are respectively disposed on the second transmission component 222. The transfer drive 221 drives the second transmission component 222 to move, so that the plurality of holding components 223 disposed on the second transmission component 222 can transfer the sample tube 300 to the first channel 114 one by one.

[0156] Each of the aforementioned holding components 223 further includes a picking position and a dispensing position. The picking position is located at the bottom of the dispensing chamber 21, and the dispensing position is located above the first channel 114. During its movement from the picking position to the dispensing position, each of the aforementioned holding components 223 will pick up a sample tube 300 at the picking position and dispensing the picked-up sample tube 300 into the first channel 114 at the dispensing position.

[0157] The second transmission component 222 is a transmission belt or transmission chain. Under the drive of the transfer drive component 221, the second transmission component 222 drives multiple picking components 223 to move cyclically, so that each picking component 223 cyclically picks up a sample tube 300 at the picking position and places the picked sample tube 300 in the first channel 114 at the discharging position.

[0158] By setting the second transmission component 222 to drive the multiple holding components 223 to circulate, the rotating assembly can continuously supply sample tubes 300 to the first channel 114 one by one. By setting the spacing between adjacent holding components 223 to be the same, the second transmission component 222 can also drive the adjacent holding components 223 to transfer sample tubes 300 to the first channel 114 one by one at a basically the same interval time under the uniform drive of the transfer drive component 221.

[0159] In some embodiments, as shown in FIG13, the first linear direction L1 is horizontal. The holding member 223 includes a connecting portion 2231 and a holding portion 2232, the connecting portion 2231 and the holding portion 2232 being connected approximately along the first linear direction L1. The connecting portion 2231 is connected to the second transmission member 222, such that the holding member 223 is connected to the second transmission member 222; the holding portion 2232 extends out of the second transmission member 222 along the first linear direction L1 and is used to hold the sample tube 300.

[0160] The picking part 2232 has a clearance groove 2233 on the side near the second transmission member 222; the supply unit 20 also includes a first rejecting member 23. The first rejecting member 23 is disposed in the delivery bin 21 and located on the movement path of the picking part 223 from the material picking position to the material discharging position, and at least one first rejecting member 23 is provided in the delivery bin 21. As the picking part 223 moves with the second transmission member 222, the first rejecting member 23 will pass through the clearance groove 2233 of each picking part 223, so that the first rejecting member 23 can reject the sample tube 300 picked up on the picking part 2232 corresponding to the clearance groove 2233, so that the first rejecting member 23 passes through the clearance groove 2233 to reject the sample tube 300 away from the first rejecting member 23 among two sample tubes arranged along the first straight direction L1, and only one sample tube 300 is retained on the picking part 2232.

[0161] It should be noted that the two sample tubes 300 arranged along the first straight line direction L1 on the receiving part 2232 have multiple arrangement states. For ease of description, the two sample tubes 300 are defined here as the first sample tube 300 and the second sample tube 300. The first sample tube 300 is close to the first rejection member 23, and the second sample tube 300 is far away from the first rejection member 23. The first rejection member 23 will push the first sample tube 300 against the second sample tube 300 to make the second sample tube 300 be rejected.

[0162] In the first case, the caps 310 of the first sample tube 300 and the second sample tube 300 are respectively close to the first rejection member 23, therefore, the cap 310 of the second sample tube 300 is close to the bottom of the first sample tube 300; in the second case, the bottoms of the first sample tube 300 and the second sample tube 300 are respectively close to the first rejection member 23, therefore, the bottom of the second sample tube 300 is close to the cap 310 of the first sample tube 300; in the third case, the cap 310 of the first sample tube 300 is close to the first rejection member 23, and the bottom of the second sample tube 300 is close to the first rejection member 23, therefore, the bottoms of the first sample tube 300 and the bottoms of the second sample tube 300 are close to each other; in the fourth case, the bottom of the first sample tube 300 is close to the first rejection member 23, and the cap 310 of the second sample tube 300 is close to the first rejection member 23, therefore, the caps 310 of the first sample tube 300 and the second sample tube 300 are close to each other. In the four scenarios described above, the first sample tube 300 and the second sample tube 300 can be placed close together along the first straight line direction L1, or they can be spaced apart by a certain distance along the first straight line direction L1. Further examples will not be provided here.

[0163] Please refer to Figure 13 again. The holding part 2232 includes a first sub-part 22321 and a second sub-part 22322. The first sub-part 22321 is connected between the connecting part 2231 and the second sub-part 22322, and the first sub-part 22321 is configured to form the clearance groove 2233. When the first rejecting member 23 passes through the clearance groove 2233, the sample tube 300 held on the holding part 2232 corresponding to the clearance groove 2233 will be adjusted to the second sub-part 22322, thereby retaining the first sample tube 300 on the second sub-part 22322.

[0164] The length of the second sub-part 22322 along the first straight direction L1 is less than the length of the first channel 114. When the pick-up member 223 moves to the feeding position, the second sub-part 22322 is completely above the first channel 114 along the first straight direction L1. Therefore, the sample tube 300 after being adjusted in position can be more accurately placed into the first channel 114, thereby enabling the channel assembly to screen the sample tube 300 more efficiently.

[0165] The picking part 2232 is configured to form a picking groove 22323. Before the picking member 223 moves from the picking position to the discharging position, the opening of the picking groove 22323 remains vertically upward. Therefore, the sample tube 300 located in the picking groove 22323 can be stably picked up. As the picking member 223 gradually approaches the discharging position, the opening of the picking groove 22323 gradually begins to deflect with the second transmission member 222. At the discharging position, the opening of the picking groove 22323 tilts along the second straight direction L2 to tilt the picked sample tube 300 towards the first channel 114.

[0166] The first rejection member 23 has a rejection surface 231, which is obliquely downward toward the bottom of the delivery chamber 21 and is disposed away from the second transmission member 222.

[0167] In addition, as shown in Figures 10-12, the supply unit 20 also includes a second rejecting member 24, a rotating member 25, and a holding member 26. The second rejecting member 24 is disposed on the rotating member 25, and the holding member 26 is used to drive the rotating member 25 and the second rejecting member 24 to remain on the movement path of the picking member 223 from the picking position to the discharging position. Therefore, when the picking member 223 passes the second rejecting member 24, the second rejecting member 24 will reject the sample tube 300 stacked above the sample tube 300 at the bottom of the corresponding picking member 223, so that only one sample tube 300 is picked up on the picking member 223, so as to avoid the picking member 223 simultaneously placing multiple sample tubes 300 into the first channel 114, which would affect the screening unit 10 from carrying out the screening work.

[0168] The dispensing chamber 21 includes a limiting baffle 211 and multiple flow guide baffles 212. The limiting baffle 211 and the multiple flow guide baffles 212 enclose and define the dispensing chamber 21. The flow guide baffles 212 and the limiting baffle 211 are used to guide the sample tubes 300 to be dispensed in batches to be stacked approximately along the first straight line direction L1 from the bottom of the dispensing chamber 21, so as to facilitate the retrieval by the retrieval component 223.

[0169] The picking part 2232 of the picking member 223 moves against the limiting baffle 211 in the delivery chamber 21, thereby limiting the picking part 2232 by the limiting baffle 211, so that the multiple picking members 223 can stably circulate and transfer the sample tube 300 between the picking position and the discharging position under the combined limiting action of the second transmission member 222 and the limiting baffle 211.

[0170] The supply unit 20 also includes a limiting component. The connecting portion 2231 of the picking member 223 moves against the limiting component on the side away from the limiting baffle 211, thereby making the sample tube 300 more stably circulated between the picking position and the discharging position under the relative limiting of the limiting component and the limiting baffle 211 along the second straight direction L2.

[0171] As shown in Figure 12, the limiting assembly includes a first limiting member 272 and a second limiting member 273. The first limiting member 272 is disposed above the second limiting member 273, and the first limiting member 272 and the second limiting member 273 are spaced apart to define a notch 271. The second rejecting member 24, the rotating member 25, and the retaining member 26 are disposed at the notch 271, and the distance between the notches 271 in the vertical direction is greater than the length of the rotating member 25 in the vertical direction, so that the rotating member 25 can rotate within the notch 271 without touching the first limiting member 272 and the second limiting member 273.

[0172] The limiting baffle 211 has a flow guide groove 2111, the opening of which faces the second rejection member 24. When the sample tube 300 stacked above the sample tube 300 at the bottom of the holding member 223 is rejected by the second rejection member 24, the rejected sample tube 300 will enter the flow guide groove 2111 and return to the delivery chamber 21 under the guidance of the flow guide groove 2111. By setting the flow guide groove 2111, the sample tube 300 rejected by the second rejection member 24 can be effectively buffered to prevent the sample tube 300 rejected by the second rejection member 24 from falling directly into the delivery chamber 21.

[0173] The second rejecting member 24 is located vertically in the middle of the flow channel 2111. When the sample tube 300 being rejected by the second rejecting member 24 is being picked up by the second rejecting member 24, the next sample tube 223 being picked up by the second rejecting member 24 has not yet moved to the area corresponding to the opening of the flow channel 2111. Therefore, the sample tube 300 rejected by the second rejecting member 24 will return to the delivery chamber 21 from the gap between the rejected sample tube 223 and the adjacent sample tube 223 waiting to be rejected. This avoids the sample tube 300 being rejected by the second rejecting member 24 from colliding with the sample tube 223 that is approaching the second rejecting member 24, which would cause the impacted sample tube 223 to shake during the movement of the second transmission member 222, affecting the stability of the sample tube 300.

[0174] Referring again to Figure 12, the second limiting member 273 gradually approaches the limiting baffle 211 from the side near the limiting baffle 211 in a vertically upward direction to form a limiting guide surface 2731. The limiting guide surface 2731 is used to limit and guide the picking member 223, which is gradually approaching the second rejecting member 24, to approach the limiting baffle 211, so that the clearance groove 2233 of the picking member 223, which is limited and guided by the second limiting member 273, can be directly facing the first rejecting member 23, thereby allowing the first rejecting member 23 to pass through the clearance groove 2233 and reject the sample tube 300 on the picking member 223 that is away from the first rejecting member 23.

[0175] The rotating member 25 includes a second abutting surface 252, which is inclined downward toward the limiting baffle 211. The retaining member 26 is used to drive the rotating member 25 to move toward the limiting baffle 211. During the process of the picking member 223 moving vertically upward with the second transmission member 222, the second abutting surface 252 abuts against the connecting part 2231 of the picking member 223 of the second rejecting member 24, so that the second rejecting member 24 can approach the picking member 223 against which the second abutting surface 252 abuts, and reject the sample tubes 300 stacked on the picking member 223, so that there are no sample tubes 300 stacked on the picking member 223 after being rejected by the second rejecting member 24.

[0176] Therefore, after a sample tube 300 is rejected by the first rejection member 23 and the second rejection member 24 respectively, the sample tube 300 is picked up by the sample tube 223 on the second sub-part 22322.

[0177] The second rejection member 24 extends along the first straight direction L1, and the length of the second rejection member 24 along the first straight direction L1 is greater than the length of the holding part 2232 of the holding member 223, so that the second rejection member 24 can completely cover the holding part 2232 to reject all the stacked sample tubes 300 on the holding part 2232.

[0178] In some embodiments, the length of the rotating member 25 in the vertical direction is greater than the distance between two adjacent holding members 223, and the rotating member 25 further includes a first abutting surface 251, which is located above the second abutting surface 252 and is obliquely upward toward the limiting baffle 211.

[0179] The retaining member 26 is used to drive the rotating member 25 to move towards the limiting baffle 211. During the vertical upward movement of the picking member 223 along with the second transmission member 222, the first abutting surface 251 first abuts against the picking member 223 after the sample tubes 300 have been removed from the stack by the second rejection member 24. At this time, the second abutting surface 252 does not abut against any of the picking members 223. When the second abutting surface 252 abuts against the picking member 223 to be rejected by the second rejection member 24, the first... One abutting surface 251 separates from the receiving component 223 after it has been rejected by the second rejecting component 24. At this time, only the second abutting surface 252 abuts against the receiving component 223, which is currently having its stacked sample tubes 300 rejected by the second rejecting component 24. As the receiving component 223 continues to move upward, the receiving component 223 that abuts against the second abutting surface 252 will pass over the second abutting surface 252 and abut against the first abutting surface 251. At this time, the sample tubes 300 stacked on the receiving component 223 have been rejected by the second rejecting component 24.

[0180] Therefore, during the process of the second rejecting member 24 rejecting the sample tube 223, at least one of the first abutting surface 251 and the second abutting surface 252 will abut against the connecting portion 2231 of the corresponding sample tube 223. This allows the second rejecting member 24 to effectively reject the sample tubes 300 stacked on the sample tube 223 under the action of the retaining member 26 and the rotating member 25, while also stably and smoothly connecting from the sample tube 223 that has already been rejected by the second rejecting member 24 to the sample tube 223 to be rejected. This avoids the second rejecting member 24, after rejecting the previous sample tube 223, directly impacting the sample tube 300 to be rejected by the next sample tube 300 under the drive of the retaining member 26, causing the impacted sample tube 223 to shake significantly and causing the sample tube 300 held by the sample tube 223 to fall directly.

[0181] The retaining member 26 is an elastic member. Under the abutting action of the lifting member 223 and the rotating member 25, the retaining member 26 is always in an elastically compressed state, and the force applied to the elastic member by the rotating member 25 changes accordingly with the movement of the lifting member 223. The elastic member can be a torsion spring, compression spring, metal sheet, etc., which stores energy after being compressed by the rotating member 25 and can release energy to the rotating member 25 to drive it to maintain at least one abutment against the lifting member 223.

[0182] On the other hand, referring to Figures 2-3 and 14, this application also provides a sample detection device. The sample detection device includes the sample tube processing module 100 described in any of the preceding claims. Therefore, the sample detection device possesses all the beneficial effects of the aforementioned sample tube processing module 100, which will not be elaborated further here.

[0183] The sample detection device further includes a detection module, which is used to detect the samples contained in the sample tube 300 selected from the first screening area 1141 or the second screening area 1161.

[0184] The loading station can be set on the detection module so that the transfer unit 30 can directly transfer the selected sample tube 300 to the detection module so that the detection module can directly detect the sample tube 300.

[0185] Furthermore, referring to Figures 2-3 and 14, this application also provides a sample testing pipeline. The sample testing pipeline includes the sample tube processing module 100 described in any of the preceding claims. Therefore, the sample testing device possesses all the beneficial effects of the aforementioned sample tube processing module 100, which will not be elaborated further here.

[0186] The sample testing pipeline also includes a track conveying module 200 and a testing module. The track conveying module 200 is connected to the sample tube processing module 100 and at least one of the testing modules. The track conveying module 200 is used to convey the sample tubes 300 selected from the first screening area 1141 or the second screening area 1161 to the testing module. The testing module is used to test the samples contained in the received sample tubes 300.

[0187] The track transport module 200 may include a first track 210 and multiple second tracks 220. The first track 210 is connected to the sample tube processing module 100 via one of the second tracks 220, and to the detection module via another of the second tracks 220. Multiple carriers may be mounted on the tracks, each carrier capable of carrying a sample tube 300. The host computer controls the movement of the carriers to coordinate with the sample tube processing module 100 and the detection module to transfer the sample tube 300.

[0188] The detection line may also include a centrifugation module, which is connected to the first track 210 via another second track 220 and is used to centrifuge samples that need to be centrifuged.

[0189] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0190] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0191] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
