[0037] Please refer to Figure 1 As shown, an embodiment of the present invention provides an in vitro diagnostic device 1.

[0038] An in vitro diagnostic device 1 includes a sample tube inlet identification device 20, a multi-station rotating bar code scanning device 30, a sample rack conveying device 40, an analyzer 50, and a control device. The control device can be a PLC or a PID. The control device is not shown in the drawings.

[0039] Please refer to Figure 2 As shown, the sample tube inlet identification device 20 is used to obtain the encoder reading value on the sample tube 90 and make a type judgment of the sample tube 90 according to preset information. The sample tube inlet identification device 20 is also used to send the sample tube 90 after type judgment to the multi-station rotating bar code scanning device 30. The multi-station rotating bar code scanning device 30 is used to perform bar code scanning on the sample tube 90. The sample rack conveying device 40 is used to convey the sample rack for the sample clamping mechanism of the sample tube inlet identification device 30 to clamp.

[0040] Specifically, in one embodiment, please refer to Figure 2 As shown, the sample tube inlet identification device 20 includes a sample bracket mechanism 21, a sample clamping mechanism 22, and an identification mechanism 230. The sample bracket mechanism 21 is used to accommodate the sample tube 90. The sample clamping mechanism 22 and the identification mechanism 230 are electrically connected to the control device. The identification mechanism 230 is arranged on the sample clamping mechanism 22 to obtain the encoder reading value on the sample tube 90 and make a type judgment of the sample tube 90 according to preset information.

[0041] Please refer to Figures 3 - 5 As shown, the sample bracket mechanism 21 includes a bottom plate 212, support columns 213, and a bracket 211. The bracket 211 is located above the bottom plate 212. There is a gap between the bottom plate 212 and the bracket 211. The bracket 211 is connected to the bottom plate 212 through the support columns 213. The bracket 211 is provided with a through hole 2111 for placing the sample tube 90, and at least one end of the through hole 2111 is in a chamfered structure.

[0042] There are multiple brackets 211, and the multiple brackets 211 are stacked in sequence. There are gaps between adjacent brackets 211 and between the brackets 211 and the bottom plate 212. The through holes 2111 on different layers of brackets 211 are coaxially arranged correspondingly, and each bracket 211 is connected to the bottom plate 212 through a support column 213. By providing multiple layers of brackets 211, accurate fixation of the sample tube 90 is achieved, and tilting of the sample tube 90 is avoided.

[0043] A sample receiving groove is provided on the bottom plate 212, and the through hole 2111 on the bracket 211 corresponds to the sample receiving groove.

[0044] In one embodiment, there are multiple through holes 2111 on the bracket 211, and multiple sample receiving grooves on the bottom plate 212. The multiple through holes 2111 on the bracket 211 correspond to the multiple sample receiving grooves on the bottom plate 212 one by one.

[0045] In one embodiment, the multiple through holes 2111 on the bracket 211 are arranged in an array.

[0046] In one embodiment, the bottom surface of the sample receiving groove is curved. The curved structure facilitates the contact and cooperation of the bottom surface of the sample tube 90, and improves the stability of the sample tube 90.

[0047] In one embodiment, both ends of the through hole 2111 are provided with a chamfer structure 21111. For the sample carrier mechanism 21 of the present invention, rounded corner structures 21111 are provided at both ports of the through hole 2111 of the bracket 211. The rounded corner on the upper surface of the bracket 211 has a guiding effect when the sample tube 90 is inserted; the rounded corner on the lower surface of the bracket 211 has a guiding effect when the sample tube 90 is pulled out, so that even if the sample tube 90 has dirt or a wrinkled barcode paper, it will not get stuck.

[0048] In one embodiment, the sample carrier mechanism 21 further includes a fastener 214. The bracket 211 and the support column 213 are connected through the fastener 214.

[0049] In one embodiment, the bracket 211 has two layers. A boss 2121 is provided on the upper surface of the bottom plate 212, and a fastening hole 21211 penetrates through the boss 2121. Counterbores that are communicated and correspond to the fastening hole 21211 are provided on the upper surface and the lower bottom surface of the bracket 211. Support columns 213 are embedded in the corresponding counterbores between the two layers of brackets 211. A fastener 214 that is threadedly engaged with the support column 213 is provided in the counterbore on the upper surface of the bracket 211, and a fastener 214 that is threadedly engaged with the support column 213 is provided in the fastening hole 21211.

[0050] In one embodiment, the fastener 214 can be a screw.

[0051] The sample carrier mechanism 21 of the present invention has a simple structure and can accurately fix and position the sample tube 90. The sample carrier mechanism 21 of the present invention can fix the sample tube 90. Due to the fixing method using the bottom plate 212 and the bracket 211, high-precision positioning of the sample tube 90 can be achieved. The above-mentioned sample carrier mechanism 21 does not have the complex structure of the traditional single-layer clamping elastic sheet type sample carrier, has a lower mold opening cost, and the positioning of the test tube is accurate, which is convenient for the multi-directional movement component 222 to grasp the sample tube 90. In addition, the above-mentioned sample carrier mechanism 21 is provided with a chamfer structure 21111 to facilitate the picking and placing of the sample tube 90.

[0052] In a specific example, the sample clamping mechanism 22 includes a material clamping component 221 and a multi-directional movement component 222 connected to the material clamping component 221. The multi-directional movement component 222 is electrically connected to the control device.

[0053] Please refer to Figure 6 As shown, the material clamping component 221 includes a first clamping arm 2211 and a second clamping arm 2212 oppositely arranged on the multi-directional driving component, and a material clamping driving part 2213 connecting the first clamping arm 2211 and / or the second clamping arm 2212. There is a gap between the first clamping arm 2211 and the second clamping arm 2212, and this gap forms a material clamping space. The material clamping driving part 2213 is installed on the multi-directional driving component. The material clamping driving part 2213 is used to drive the first clamping arm 2211 and / or the second clamping arm 2212 to act to clamp or release the sample tube 90. The material clamping driving part 2213 is electrically connected to the control device.

[0054] The multi-directional movement component 222 is connected to the material clamping driving part 2213. The material clamping driving part 2213 can be a driving motor. The first clamping arm 2211 and the second clamping arm 2212 can be connected and rotated towards each other or in reverse through a lead screw structure. The material clamping driving part 2213 can also be a driving cylinder, a driving motor, etc.

[0055] In a specific example, the material clamping driving part 2213 is connected to the first clamping arm 2211 and the second clamping arm 2212 to drive the first clamping arm 2211 and the second clamping arm 2212 to act.

[0056] In a specific example, on the opposite surfaces of the first clamping arm 2211 and the second clamping arm 2212, there is one or several of grooves, bumps and ridges for increasing the friction force with the sample tube 90. For example, on the opposite surfaces of the first clamping arm 2211 and the second clamping arm 2212, there are grooves for increasing the friction force with the sample tube 90, and the inner diameter of the grooves is between 0.1 mm and 1 mm; for example, on the opposite surfaces of the first clamping arm 2211 and the second clamping arm 2212, there are bumps for increasing the friction force with the sample tube 90, and the outer diameter of the bumps is between 0.1 mm and 1 mm; for example, on the opposite surfaces of the first clamping arm 2211 and the second clamping arm 2212, there are ridges for increasing the friction force with the sample tube 90, the length of the ridges is 1 mm - 2 mm, and the width of the ridges is 0.1 mm - 0.5 mm. It is not difficult to understand that in other embodiments, the opposite surfaces of the first clamping arm 2211 and the second clamping arm 2212 may be in a rough structure, as long as the purpose of increasing the friction force between the opposite surfaces of the first clamping arm 2211 and the second clamping arm 2212 and the sample tube 90 can be achieved.

[0057] In a specific example, the opposite surfaces of the first clamping arm 2211 and the second clamping arm 2212 are both in a curved surface shape that is concave inward, so as to adapt the opposite surfaces of the first clamping arm 2211 and the second clamping arm 2212 to the outer wall of the sample tube 90 and improve the firmness of grasping.

[0058] In a specific example, the clamping component 221 further includes an anti-sticking component 2214. The anti-sticking component 2214 includes an anti-sticking pressing member 22141, an anti-sticking base 22142 and an anti-sticking elastic member 22143. The anti-sticking base 22142 is installed on the multi-directional driving component. A part of the anti-sticking pressing member 22141 is arranged between the first clamping arm 2211 and the second clamping arm 2212. The anti-sticking elastic member 22143 is arranged between the anti-sticking pressing member 22141 and the anti-sticking base 22142. When the anti-sticking elastic member 22143 is in a compressed and reset state, the anti-sticking pressing member 22141 does not protrude from the clamping space, that is, when the anti-sticking elastic member 22143 is in a compressed and reset state, the ends of the anti-sticking pressing member 22141 located in the clamping space do not extend out of the clamping space.

[0059] In a specific example, the anti-sticking component 2214 further includes an anti-sticking guide rail 22144. The anti-sticking guide rail 22144 is installed on the anti-sticking base 22142. The extending direction of the anti-sticking guide rail 22144 is consistent with the axial direction of the anti-sticking pressing member 22141, and the anti-sticking pressing member 22141 is slidably connected to the anti-sticking guide rail 22144.

[0060] In a specific example, the anti-sticking component 2214 further includes a limit connection block 22145 and a guide shaft 22146. The limit connection block 22145 is connected to the anti-sticking base 22142, the guide shaft 22146 is connected to the limit connection block 22145, the anti-sticking elastic member 22143 extends along the guide shaft 22146, and can perform telescopic movement along the axial direction of the guide shaft 22146.

[0061] In a specific example, the anti-sticking pressing member 22141 includes an anti-sticking pressing strip 221411 and an anti-sticking pressing block 221412. The anti-sticking pressing strip 221411 is connected to the anti-sticking pressing block 221412. A part of the anti-sticking pressing strip 221411 is disposed between the first clamping arm 2211 and the second clamping arm 2212, and the anti-sticking pressing block 221412 is slidably connected to the anti-sticking guide rail 22144.

[0062] In a specific example, the anti-sticking pressing member 22141 further includes a fitting block 221413. The fitting block 221413 is connected to the anti-sticking pressing block 221412, and the fitting block 221413 is also in anti-sticking elastic connection and cooperation.

[0063] In a specific example, one end of the guide shaft 22146 is fixed on the limit connection block 22145. A part of the anti-sticking pressing member 22141 is disposed through the guide shaft 22146 and can move along the guide shaft 22146. One end of the anti-sticking elastic member 22143 is disposed through the fitting block 221413.

[0064] In a specific example, the anti-sticking elastic member 22143 is an anti-sticking spring. The anti-sticking elastic member 22143 is sleeved on the guide shaft 22146.

[0065] The sample tube feeding and identifying device 20 of the present invention is provided with a material clamping component 221. When clamping the sample tube 90, it can effectively prevent the problem of the sample tube 90 sticking, and avoid related failures and problems caused by the sample tube 90 sticking to the clamping arm. When the material clamping component 221 of the present invention is in use, the material clamping component 221 moves to the position of the sample tube 90, and the material clamping driving component 2213 drives the first clamping arm 2211 and the second clamping arm 2212 to open. Driven by the multi-directional motion component 222 connected thereto, the material clamping component 221 moves above the sample tube 90, and the first clamping arm 2211 and the second clamping arm 2212 are gradually pressed down to both sides of the sample tube 90. When the sample tube 90 contacts the anti-sticking pressing member 22141, it will compress the anti-sticking elastic member 22143. When the anti-sticking elastic member 22143 is compressed to a certain position, the material clamping driving component 2213 drives the first clamping arm 2211 and the second clamping arm 2212 to close and clamp the sample tube 90. The multi-directional motion component 222 drives the material clamping component 221 to move to a predetermined position, and the material clamping driving component 2213 drives the first clamping arm 2211 and the second clamping arm 2212 to open. At this time, the anti-sticking elastic member 22143 gradually resets under the action of the elastic restoring force, so that the sample tube 90 is separated from the first clamping arm 2211 and the second clamping arm 2212, and the multi-directional motion component 222 drives the material clamping component 221 to reset, thus realizing the anti-sticking of the sample tube 90.

[0066] The sample tube feeding and identifying device 20 of the present invention can realize the automatic identification and sorting of the sample tube 90. For sample tubes 90 of various specifications, it can automatically identify and be compatible with various models of sample tubes 90, without manual participation in sorting, reducing labor costs, saving manual time, and greatly reducing the test and detection costs. The automatic identification speeds up the sorting speed and improves the sorting efficiency. When in use, the sample tube 90 does not need to be manually sorted and placed into the analyzer 50. Through the sample tube feeding and identifying device 20 of the present invention, the model identification and sorting of the sample tube 90 and subsequent sending for testing or de-capping by the de-capping mechanism can be quickly realized, and the degree of automation is greatly improved.

[0082] Please refer to Figure 8As shown in the figure, the multi-station rotary bar code scanning device 30 includes a rotating mechanism 310 and a bar code scanning mechanism 320. The rotating mechanism 310 includes a plurality of rotatable rotating seats. The bar code scanning mechanism 320 and the plurality of rotating seats are arranged in sequence in a row. There are intervals between the bar code scanning mechanism 320 and the rotating seats, and between adjacent rotating seats. At least two of the plurality of rotating seats are used to place sample tubes 90 with different lengths, and the height difference between the two rotating seats is equal to the height difference between the two sample tubes 90 (the lengths of the two sample tubes 90 are different, that is, different specifications). The rotating mechanism 310 and the bar code scanning mechanism 320 are electrically connected to the control device.

[0083] In a specific example, refer to Figure 8 As shown in the figure, the rotating seat includes a rotatable first rotating seat 311 and a rotatable second rotating seat 312. The bar code scanning mechanism 320, the first rotating seat 311, and the second rotating seat 312 are arranged in sequence. There are intervals between the bar code scanning mechanism 320 and the first rotating seat 311, and between the first rotating seat 311 and the second rotating seat 312. The first rotating seat 311 is used to place a first specification sample tube 91 with a shorter length, and the second rotating seat 312 is used to place a second specification sample tube 92 with a longer length. The height difference between the first rotating seat 311 and the second rotating seat 312 is equal to the height difference between the first specification sample tube 91 and the second specification sample tube 92. When the rotating seat includes a rotatable first rotating seat 311 and a rotatable second rotating seat 312, the multi-station rotary bar code scanning device 30 constitutes a two-station rotary bar code scanning device.

[0084] For example, refer to Figure 1 As shown in the figure, the length of the first specification sample tube 91 is 75 mm, and the length of the second specification sample tube 92 is 100 mm. Then the second rotating seat 312 is 25 mm higher than the first rotating seat 311. The second rotating seat 312 places the second specification sample tube 92 with a height of 100 mm, and the first rotating seat 311 places the first specification sample tube 91 with a height of 75 mm. The distance between the bar code scanning mechanism 320 and the first rotating seat 311 is 80 mm, and the scanning width of the bar code scanning mechanism 320 is about 100 mm, which can completely cover the first specification sample tube 91. The distance between the bar code scanning mechanism 320 and the second rotating seat 312 is 135 mm, and the scanning width of the bar code scanning mechanism 320 is about 180 mm, which can completely cover the second specification sample tube 92. The center of the bar code scanning mechanism 320 and the center of the first specification sample are on the same horizontal line.

[0085] In a specific example, refer to Figure 1As shown, the rotating mechanism 310 further includes a rotation driving component 313. The rotation driving component 313 is connected to the first rotating seat 311 and the second rotating seat 312. The rotation driving component 313 drives the first rotating seat 311 and the second rotating seat 312 to rotate at a constant speed. The rotation driving component 313 is electrically connected to the control device. The number of rotation driving components 313 can be two. When the number of rotation driving components 313 is two, the two rotation driving components 313 are respectively connected to and control the first rotating seat 311 and the second rotating seat 312. The control device can control the rotation period of the rotation driving component 313 to drive the first rotating seat 311 and the second rotating seat 312, that is, how many turns to rotate. For example, the control device can control the rotation driving component 313 to drive the first rotating seat 311 and the second rotating seat 312 to rotate 1 / 3 turn, 1 / 2 turn, etc. In this way, the code scanning mechanism 320 can complete the code scanning work of a sample tube 90 by corresponding code scanning 3 times, 2 times, etc.

[0086] In a specific example, refer to Figure 1 As shown, the multi-station rotating bar code scanning device 30 further includes a support mechanism 330. The support mechanism 330 includes a support seat 331, and the first rotating seat 311 and the second rotating seat 312 are both rotatably connected to the support seat 331.

[0087] In a specific example, refer to Figure 1 As shown, the support mechanism 330 further includes a support frame 332. The support frame 332 is connected to the support seat 331, and the code scanning mechanism 320 is arranged on the support frame 332.

[0088] In a specific example, refer to Figure 9 and Figure 10As shown, the multi-station rotating bar code scanning device 30 further includes a sample tube limiting mechanism 340. The sample tube limiting mechanism 340 is respectively arranged on the first rotating seat 311 and the second rotating seat 312, and is respectively used for limiting the position of the first specification sample tube 91 and the second specification sample tube 92. The multi-station rotating bar code scanning device 30 of the present invention is provided with a sample tube limiting mechanism 340 to realize the position limitation of the sample tube 90, and avoid the position movement of the sample tube 90 when rotating with the first rotating seat 311 or the second rotating seat 312. Specifically, the sample tube limiting mechanism 340 is used for limiting the position of the first specification sample tube 91. After the first specification sample tube 91 is placed on the first rotating seat 311, the sample tube limiting mechanism 340 limits the first specification sample tube 91 to prevent the displacement of the first specification sample tube 91 and improve the scanning efficiency. The sample tube limiting mechanism 340 is used for limiting the position of the second specification sample tube 92. After the second specification sample tube 92 is placed on the second rotating seat 312, the sample tube limiting mechanism 340 limits the second specification sample tube 92 to prevent the displacement of the second specification sample tube 92 and improve the scanning efficiency.

[0089] In a specific example, referring to Figure 9 and Figure 10 As shown, the sample tube limiting mechanism 340 includes a limiting fixed seat 341 and a first limiting strip 342. The first limiting strip 342 is installed on the limiting fixed seat 341, and a plurality of first limiting strips 342 are arranged on the limiting fixed seat 341. There is a gap between adjacent first limiting strips 342, and the plurality of first limiting strips 342 enclose a limiting space for accommodating the first specification sample tube 91 or the second specification sample tube 92. The sample tube limiting mechanism 340 of the multi-station rotating bar code scanning device 30 of the present invention includes a limiting fixed seat 341 and a first limiting strip 342. A plurality of first limiting strips 342 are arranged on the limiting fixed seat 341, and the plurality of first limiting strips 342 form a limiting space for accommodating the first specification sample tube 91 or the second specification sample tube 92. Such a setting can facilitate the placement of the first specification sample tube 91 or the second specification sample tube 92 into the limiting space, which is convenient to take, time-saving and labor-saving.

[0090] In a specific example, the first limiting strip 342 is elastic. Preferably, the first limiting strip 342 can be an elastic filamentous structure made of spring steel wire, spring steel strip, or other metal materials. The elastic setting of the first limiting strip 342 enables its own bending and resetting. When it is necessary to insert the first specification sample tube 91 or the second specification sample tube 92, the first limiting strip 342 can be manually pulled outwards to facilitate the insertion of the first specification sample tube 91 or the second specification sample tube 92. Or when the outer diameter of the first specification sample tube 91 or the second specification sample tube 92 is slightly larger than the radial dimension of the limiting space, the elastic deformation of the first limiting strip 342 can adapt to the first specification sample tube 91 or the second specification sample tube 92 without replacing the limiting mechanism, increasing the adaptation range.

[0091] Furthermore, the first limiting strip 342 is a filamentous structure, and the diameter of the first limiting strip 342 is 1 mm - 5 mm. For example, the diameter of the first limiting strip 342 is 1 mm, 2 mm, 3 mm, 4 mm, 5 mm or other non-integer values. The diameter of the first limiting strip 342 should not be too small. If the diameter of the first limiting strip 342 is less than 1 mm, the strength is low and it cannot well limit and fix the first specification sample tube 91 or the second specification sample tube 92. The diameter of the first limiting strip 342 should not be too large. If the diameter of the first limiting strip 342 is greater than 5 mm, on the one hand, the cost is high, and on the other hand, the distance between adjacent first limiting strips 342 will be reduced, reducing the scanning range and the scanning accuracy.

[0092] In a specific example, one end of the first limiting strip 342 away from the limiting fixing seat 341 is bent to form a first bending portion and this end extends outwards.

[0093] The setting of the first bending portion can play a role in clamping the first specification sample tube 91 or the second specification sample tube 92. Since the first bending portion tends to be inside the limiting space, that is, the distance formed by multiple first bending portions is smaller than the radial dimension of the limiting space. In this way, the first specification sample tube 91 or the second specification sample tube 92 can be clamped. Even if the outer diameter of the first specification sample tube 91 or the second specification sample tube 92 is smaller than the radial dimension of the limiting space, the limiting and fixing effect of the first specification sample tube 91 or the second specification sample tube 92 can be achieved through the clamping action of multiple first bending portions.

[0094] In a specific example, one end of the first limiting strip 342 away from the limiting fixed seat 341 bends towards the limiting space to form a first bending part. In the multi-station rotating bar code scanning device 30 of the present invention, one end of the first limiting strip 342 away from the limiting fixed seat 341 bends and the end extends outwards. In this way, the ends of the respective first limiting strips 342 extend outwards, and the opening becomes larger, facilitating the placement of the first specification sample tube 91 or the second specification sample tube 92 into the limiting space.

[0095] In a specific example, the sample tube limiting mechanism 340 further includes a second limiting strip 343. The second limiting strip 343 is installed on the limiting fixed seat 341. A plurality of second limiting strips 343 are provided on the limiting fixed seat 341. There is a gap between adjacent second limiting strips 343. The length of the second limiting strip 343 is greater than the length of the first limiting strip 342. The plurality of second limiting strips 343 and the first limiting strip 342 together enclose a limiting space. In the multi-station rotating bar code scanning device 30 of the present invention, a plurality of second limiting strips 343 are provided. The plurality of second limiting strips 343 and the first limiting strip 342 together enclose a limiting space for accommodating the first specification sample tube 91 or the second specification sample tube 92. The second limiting strip 343 is longer than the first limiting strip 342. Such a setting can be applicable to the placement of the first specification sample tube 91 or the second specification sample tube 92 with various different lengths into the limiting space, facilitating taking and having a wide adaptability.

[0096] In a specific example, the second limiting strip 343 has elasticity. Preferably, the second limiting strip 343 can be an elastic filamentous structure made of spring steel wire, spring steel strip, or other metal materials. The setting that the second limiting strip 343 has elasticity can enable its own bending and resetting. When it is necessary to insert the first specification sample tube 91 or the second specification sample tube 92, the second limiting strip 343 can be manually pulled outwards first to facilitate the placement of the first specification sample tube 91 or the second specification sample tube 92. Or when the outer diameter of the first specification sample tube 91 or the second specification sample tube 92 is slightly larger than the radial dimension of the limiting space, the elastic deformation of the second limiting strip 343 can adapt to the first specification sample tube 91 or the second specification sample tube 92 without replacing the limiting mechanism, increasing the adaptation range.

[0097] Further, the second limiting strip 343 is in a filamentous structure, and the diameter of the second limiting strip 343 is 1 mm - 5 mm. For example, the diameter of the second limiting strip 343 is 1 mm, 2 mm, 3 mm, 4 mm, 5 mm or other non-integer values. The diameter of the second limiting strip 343 should not be too small. If the diameter of the second limiting strip 343 is less than 1 mm, the strength is low and it cannot well limit and fix the second specification sample tube 92 or the second specification sample tube 92. The diameter of the second limiting strip 343 should not be too large. If the diameter of the second limiting strip 343 is greater than 5 mm, on the one hand, the cost is high, and on the other hand, the distance between adjacent second limiting strips 343 will be reduced, reducing the scanning range and lowering the scanning accuracy.

[0098] In a specific example, one end of the second limiting strip 343 away from the limiting fixing seat 341 is bent to form a second bending portion and this end extends outward. The multi-station rotating bar code scanning device 30 of the present invention is provided such that one end of the second limiting strip 343 away from the limiting fixing seat 341 is bent and the end extends outward. In this way, the ends of the respective second limiting strips 343 extend outward, increasing the opening and facilitating the placement of the first specification sample tube 91 or the second specification sample tube 92 into the limiting space.

[0099] In a specific example, one end of the second limiting strip 343 away from the limiting fixing seat 341 is bent toward the inside of the limiting space to form a second bending portion.

[0100] The setting of the second bending portion can play a role in clamping the first specification sample tube 91 or the second specification sample tube 92. Since the second bending portion tends to be inside the limiting space, that is, the distance formed by the plurality of second bending portions is smaller than the radial dimension of the limiting space. In this way, the first specification sample tube 91 or the second specification sample tube 92 can be clamped. Even if the outer diameter of the first specification sample tube 91 or the second specification sample tube 92 is smaller than the radial dimension of the limiting space, the limiting and fixing effect of the first specification sample tube 91 or the second specification sample tube 92 can be achieved through the clamping action of the plurality of second bending portions.

[0101] In a specific example, referring to Figure 10 As shown, the sample tube limiting mechanism 340 further includes a fixed base 344. A card slot is provided on the fixed base 344. The limiting fixing seat 341 is annular, and the limiting fixing seat 341 is arranged on the fixed base 344 and the limiting space corresponds to the card slot.

[0102] In a specific example, referring to Figure 10As shown in the figure, the sample tube limiting mechanism 340 further includes a shock absorber 345. The shock absorber 345 is arranged in the card slot. The shock absorber 345 can be a rubber pad. The multi-station rotary bar code scanning device 30 of the present invention is provided with the shock absorber 345, which is arranged in the card slot, and can buffer and shock absorb when the first specification sample tube 91 or the second specification sample tube 92 is placed, so as to avoid damage to the first specification sample tube 91 or the second specification sample tube 92.

[0103] Setting the sample tube limiting mechanism 340 reduces the risk of mis-scanning, takes less time, reduces labor costs, and can be applicable to test tubes with different outer diameters for bar code identification.

[0104] When the multi-station rotary bar code scanning device 30 of the present invention performs bar code scanning, it is not necessary to manually adjust the position of the sample tube 90, greatly improves the bar code scanning efficiency, has a low cost, can improve the degree of automation of bar code scanning, reduces manual participation, reduces the risk of mis-scanning, takes less time, reduces labor costs, avoids long-term human contact with the sample tube 90, reduces the risk of sample contamination, and indirectly improves the accuracy of the analysis results. When the multi-station rotary bar code scanning device 30 of the present invention is in use, sample tubes 90 with different lengths are correspondingly placed on the rotating seats at different heights in sequence, and the rotating seats are rotated by a predetermined number of turns, such as rotating half a turn or 1 / 3 turn each time, and correspondingly rotating 2 times or 3 times can complete the bar code scanning work of a sample tube on one rotation. After the bar code scanning is completed, the sample tube 90 is placed at a predetermined position. The work that requires manual participation is to place the sample tube 90 on the corresponding rotating seat, or the picking and placing work of the sample tube 90 can also be completed by other multi-directional movement components 222. Since there are intervals between the bar code scanning mechanism 320 and the rotating seat, and between adjacent rotating seats, the bar code scanning range of the bar code scanning mechanism 320 is increased, and the interference between adjacent rotating seats is small. Further, different rotating seats are used to place sample tubes with different lengths. For example, the height difference between adjacent rotating seats is equal to the height difference between adjacent sample tubes. Therefore, the previous rotating seat and the sample tube 90 on it will not affect the scanning work of the subsequent rotating seat and the sample tube 90 on it, that is, the height of the previous sample tube 90 is lower than the height of the subsequent sample tube 90, and no bar code scanning occlusion will be caused.

[0117] In one embodiment, referring to Figure 13As shown in the figure, the jacking limit mechanism 43 includes a jacking limit base 431, a jacking limit substrate 432, a jacking limit rod 433, and a limit driving component 434. The jacking limit substrate 432 is movably connected to the jacking limit base 431 and can move vertically along the jacking limit base 431. A working station 439 is provided on the jacking limit substrate 432. The jacking limit rod 433 is connected to the jacking limit substrate 432 and is distributed around the periphery of the working station 439. The limit driving component 434 is connected to the jacking limit substrate 432. The limit driving component 434 is electrically connected to the control device.

[0118] In one embodiment, the jacking limit mechanism 43 further includes a jacking limit guide rail 435, a jacking limit slider 436, a jacking limit roller 437, and a cam 438. The jacking limit guide rail 435 is provided on the jacking limit base 431 and extends in the vertical direction. The jacking limit slider 436 is fixedly connected to the jacking limit substrate 432 and slidably connected to the jacking limit guide rail 435. The jacking limit slider 436 has an elongated relief channel 4361. The jacking limit roller 437 is rotatably connected in the relief channel 4361. The limit driving component is rotatably connected to the jacking limit roller 437 through the cam 438. By providing the jacking limit guide rail 435, the jacking limit slider 436, the jacking limit roller 437, and the cam 438, the sample rack transfer device 40 of the present invention realizes the movement of the jacking limit substrate 432 in the vertical direction, reduces the volume of the jacking limit mechanism 43, and reduces the occupied space of the entire sample rack transfer device 40.

[0119] In one embodiment, a sample rack recycling mechanism 45 is further included. The sample rack recycling mechanism 45 includes a recycling tray 451 and a tray guide rail 452. A buffer station 453 is provided on the recycling tray 451. The working station 439 is docked with the buffer station 453. The tray guide rail 452 is provided on the recycling tray 451 and extends to the buffer station 453 and the working station 439. By providing the sample rack recycling mechanism 45, the sample rack transfer device 40 of the present invention can realize the recycling of the sample rack after sampling, saves the time cost of manual recycling, and has a high degree of recycling automation. During recycling, after the sample rack at the working station 439 completes sampling or clamping of the sample tube, it is pushed by the sample rack pushing mechanism 42 onto the tray guide rail 452. When the next sample rack is pushed onto the tray guide rail 452, it will push the previous sample rack to move forward a distance equal to the thickness of one sample rack along the tray guide rail 452, and so on, until the sample racks on the tray guide rail 452 are full. It can be seen that the sample rack recycling mechanism 45 can directly rely on the sample rack pushing mechanism and does not require special power support.

[0120] The sample rack transfer device 40 of the present invention has a simple structure, a small structural space, low cost and wide adaptability. When the sample rack transfer device 40 of the present invention is in use, after placing the sample rack on the transfer component 412, no manual intervention is required. After the transfer component 412 transfers the sample rack to the transfer station 411, the sample rack pushing mechanism 42 pushes the sample rack at the transfer station 411 to the working station 439. The lifting and limiting mechanism 43 limits and fixes the sample rack at the working station 439. The sample rack completes the sample aspiration or grasping work at the working station 439. The barcode scanner 44 acquires the information of the sample rack at the working station 439. After the above processes are completed, the lifting and limiting mechanism 43 releases the sample rack, and the sample rack continues to be pushed by the sample rack pushing mechanism 42 to a defined position for recycling.

[0142] An embodiment of the invention further provides an in vitro diagnostic device 1.

[0143] An embodiment of the present invention further provides a usage method of the multi-station rotating bar code scanning device 30.

[0144] A usage method of a multi-station rotating bar code scanning device 30 includes the following steps.

[0145] This method performs the bar code scanning work on two specifications of sample tubes 90. The first is the first specification sample tube 91, and the other is the second specification sample tube 92.

[0146] When the first specification sample tube 91 is obtained, it is correspondingly placed on the first rotating seat 311. The first rotating seat 311 rotates 1 / 3 of a circle, and after rotating 3 times, the bar code scanning work of the first specification sample tube 91 can be completed. After the scanning is completed, the first specification sample tube 91 is manually placed at a predetermined position.

[0147] When manually taking the second specification sample tube 92, place it on the second rotating seat 312, and the second rotating seat 312 rotates 1 / 3 of a circle. The scanning of the second specification sample tube 92 can be completed after rotating 3 times. After the scanning is completed, the second specification sample tube 92 is manually placed in the predetermined position.

[0148] When using the multi-station rotary barcode scanning device 30 of the present invention, it is necessary to simultaneously have position requirements for the barcodes of the sample tubes 90. For example, the first sample tube 91 is a first specification sample tube 91 with a length of 75 mm, and the other is a second specification sample tube 92 with a length of 100 mm. Since the second rotating seat 312 is 25mm higher than the first rotating seat 311 in front, the height of the sample tube limiting mechanism 340 on the first rotating seat 311 can be set to 45mm, and the height of the sample tube limiting mechanism 340 on the second rotating seat 312 can be set to 30mm; then the barcode length of the 100mm second-specification sample tube 92 is maximum 55mm (including a 5mm lower static area and a barcode effective length of 45mm), and the barcode pasting requires that a minimum of 15mm be reserved at the bottom of the second-specification sample tube 90, so that the sample tube limiting mechanism 340 on the first rotating seat 311 will not block the scanning of the second-specification sample tube 92, that is, the ultimate purpose is to require that the total height of the rotating seat close to the code scanning mechanism 320 and the sample tube limiting mechanism 340 thereon cannot block the barcode of the sample tube 90 on the rotating seat.

[0149] An embodiment of the present invention further provides a method for automatically identifying the model of a sample tube 90 .

[0150] A method for automatically identifying the model of a sample tube 90 includes the following steps:

[0151] Grab the sample tube 90.

[0152] Obtain the encoder reading on the sample tube 90 and determine the type of the sample tube 90 based on the preset information. When the encoder reading is within the first range, it indicates that the sample tube 90 is a sample tube of the first specification without a cap; when the encoder reading is within the second range, it indicates that the sample tube 90 is a sample tube of the first specification with a cap; when the encoder reading is within the third range, it indicates that the sample tube 90 is a sample tube of the second specification without a cap; when the encoder reading is within the fourth range, it indicates that the sample tube 90 is a sample tube of the second specification with a cap; and the same applies to sample tubes 90 of other specifications.

[0153] If the sample tube is identified as uncapped (e.g., a first specification uncapped sample tube or a second specification uncapped sample tube), the sample tube 90 is moved to enter testing. If the sample tube is identified as capped (e.g., a first specification capped sample tube or a second specification capped sample tube), the sample tube 90 is moved to a decapping mechanism for decapping before entering testing. The method for automatically identifying the model of the sample tube 90 of the present invention is simple to operate, requires minimal manual intervention, and has a high degree of automation.

[0154] An embodiment of the present invention further provides an in vitro diagnostic method.

[0155] An in vitro diagnostic method using the in vitro diagnostic device 11 includes the following steps:

[0156] Obtain the sample rack at the general sample injection device 61, enter the pipeline device 10, the sample rack from the pipeline device 10 enters the transfer component 412 of the sample rack transfer device 40, the transfer component 412 sends the sample rack to the transfer station 411, after the first transfer position sensor 4127 and the second transfer position sensor 4128 detect that the sample tube reaches the transfer station 411, the sample rack pushing mechanism 42 pushes the sample rack to the working station 439.

[0157] The sample clamping mechanism 22 of the sample tube injection and identification device 20 clamps the sample tube 90 on the sample rack at the working station 439, and the identification mechanism 230 provided on the sample clamping mechanism 22 obtains the encoder reading value on the sample tube 90 and makes a type judgment of the sample tube 90 according to the preset information.

[0158] The clamping component 221 and the multi-directional movement component 222 of the clamping mechanism 22 cooperate to send the sample tube 90 that meets the test requirements to the multi-station rotating bar code scanning device 30. After the multi-station rotating bar code scanning device 30 obtains the bar code of the sample tube 90, the clamping component 221 and the multi-directional movement component 222 of the clamping mechanism 22 cooperate to send the sample tube 90 from the multi-station rotating bar code scanning device 30 to the sample rack at the buffer device 70 for storage.

[0159] The mobile sample loading device 80 obtains the sample tube 90 on the sample rack at the buffer device 70 and sends the sample tube 9 to the analyzer 50.

[0160] In addition, when there is an emergency sample, the emergency sample can be directly connected to the buffer device 70, and the emergency sample injection device 62 can directly enter the sample rack in the buffer device 70 to wait for analysis.
