Description

Technical Field

[0001] The invention belongs to the technical field of medical detection, and particularly relates to a comprehensive multi-project automated specific protein analyzer. Background Art

[0002] The fully automatic specific protein analyzer is a common instrument in the field of medical testing. It is usually used to perform various tests on human samples such as whole blood, serum, plasma, peripheral blood, urine, cerebrospinal fluid, and stool lysate. Before the sample test, the sample is usually placed in a sample tube and automatically transferred to the test instrument through the track of the test instrument for testing.

[0003] In order to meet the detection and storage requirements of different samples, the mainstream biochemical analysis currently uses a single optical module for analysis, which cannot fully cover the detection of specific proteins and other items, while the mainstream specific protein analyzers cannot cover biochemical detection items. At the same time, the biochemical analyzers currently on the market do not have the puncture sampling function, and the specific protein analysis on the market does not have the detection of other sample types such as urine and feces, nor does it have the ISE electrolyte detection function. In addition, the two analyzers currently on the market do not have independent sample cup dilution and re-testing functions.

[0076] The present application is further described in detail below in conjunction with specific drawings. In the description of this embodiment, unless otherwise specified, the terms "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the present application must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application.

[0077] like Figure 1 and Figure 2 As shown, an automated specific protein analyzer for comprehensive multi-item detection provided by the present invention mainly includes a support platform, an online conveying track 1100, an expedited processing component, a double sample arm sampling mechanism 2000, a sample tray 1600, a reagent tray 1700, a reaction tray 1400, a first reagent arm 1500, an ISE electrolyte module 1200 and a dual optical path detection module.

[0078] The online conveying track 1100 includes a base 100, a first conveying track 101, a second conveying track 102, a loading platform 103 and an unloading platform 104, wherein the first conveying track 101 is arranged close to one side of the support platform, and the second conveying track 102 is arranged away from the support platform. The first conveying track 101 and the second conveying track 102 are arranged in parallel and have the same conveying direction. The loading platform 103 and the unloading platform 104 are arranged between the first conveying track 101 and the second conveying track 102. The loading platform 103 is used for the transmission and placement of sample tubes detected by the current instrument, and the unloading platform 104 is used for the transmission and placement of sample tubes after sampling by the current detection instrument. The first conveying track 101 is used for the transmission of samples detected by the current instrument, and the second conveying track 102 is used for the transmission of samples between two adjacent detection instruments.

[0079] Specifically, Figure 5-Figure 6As shown, the online conveying track 1100 is arranged on the supporting platform, which mainly includes a base 100, on which a first mounting platform is provided; the first conveying track 101 is arranged on the first mounting platform of the base 100. In this embodiment, in order to facilitate the installation of various components, a bracket is arranged on the first mounting platform, and the first conveying track 101 is arranged on the bracket, so that a certain space is left between the first conveying track 101 and the first mounting platform for the installation of the transmission component. The first conveying track 101 is used for the transmission of the sample tube group to be tested of the current detection instrument; in this embodiment, the sample tube group includes a sample rack and a plurality of sampling tubes arranged on the sample rack.

[0080] The loading platform 103 is arranged on one side of the first conveying track 101. The loading platform 103 is connected to the first conveying track 101, that is, the sample tube group to be tested can be pushed from the loading platform 103 to the first conveying track 101. The loading platform 103 is used for placing the sample tube group of the current detection instrument before sampling and detection. In order to facilitate the movement of the sample tube group from the loading platform 103 to the first conveying track 101, a first pushing block 1058 that can move back and forth is arranged above the loading platform 103. Figure 5 and Fig. 9 As shown, the first push block 1058 pushes the sample tube group onto the first conveying track 101. In this embodiment, the moving direction of the first push block 1058 is perpendicular to the conveying direction of the first conveying track 101. In this embodiment, in order to facilitate the sample tube group to move only in a straight line during the movement to the first conveying rail 101, the width of the loading platform 103 is adapted to the length of the sample rack of the sample tube group. At the same time, a loading limit rib is also provided on the side of the loading platform 103 to prevent the sample rack from moving in a direction perpendicular to the loading platform 103. In this embodiment, a first trigger switch 1071 is provided on one side of the first conveying track 101, as shown in FIG. Fig.16 As shown, when the sample tube group touches the first trigger switch 1071, the first conveying track 101 performs sample conveying.

[0081] The unloading platform 104 is arranged on one side of the first conveying track 101. The unloading platform 104 is arranged on the same side as the loading platform 103. The unloading platform 104 is connected to the first conveying track 101 so that the sample tube group after sampling can be pushed from the first conveying track 101 to the unloading platform 104. The unloading platform 104 is used for temporary storage and placement of the sample tube group after sampling or transfer to the next detection instrument. A second pushing block 601 capable of reciprocating linear movement is arranged above the first conveying track 101. Figure 6 and Fig.19As shown, the second pushing block 601 can push the sample tube group located on the first conveying track 101 to the unloading platform 104. In this embodiment, the moving path of the second pushing block 601 is perpendicular to the conveying path of the first conveying track 101. In this embodiment, in order to facilitate the sample tube group to move only in a straight line from the first conveying rail 101 to the unloading platform 104, the width of the unloading platform 104 is adapted to the length of the sample rack of the sample tube group. At the same time, an unloading limit rib is also provided on the side of the unloading platform 104 to prevent the sample rack from moving in a direction perpendicular to the unloading platform 104. In this embodiment, a second trigger switch 1072 is provided on the first conveying track 101. Fig.18 As shown, when the sample tube group after sampling touches the second trigger switch 1072, the first conveying track 101 stops conveying samples, and the second pushing block 601 pushes the sample tube group on the first conveying track 101 to the unloading platform 104. The first trigger switch 1071 and the second trigger switch 1072 are both prior art, equivalent to the position detection device, and will not be described in detail here.

[0082] The expedited processing assembly 300 is disposed on the other side of the first conveying track 101 and corresponds to the position of the loading platform 103. The expedited processing assembly 300 is provided with an expedited push block 308 that moves back and forth. Figure 6 and Fig.11 As shown, when emergency sampling and testing is required, the expedited push block 308 will push the sample tube group that is currently on the first conveying track 101 and has not entered the sampling procedure back to the loading platform 103, thereby leaving a preset space on the first conveying track 101, making it easier for the operator to place the expedited sample tube group on the first conveying track 101 to enter the next sampling and testing process.

[0083] The present application sets an expedited processing component 300 on the opposite side of the loading platform 103 of the first conveying track 101. The expedited processing component 300 is provided with a reciprocating expedited push block 308. Through the movement of the expedited push block 308, a placement space for an expedited sample tube group is reserved on the first conveying track 101, thereby realizing expedited processing of samples on the same detection instrument, without the need for an additional separate expedited sample detection instrument, reducing the equipment cost of the detection organization, and at the same time, not disrupting the original detection order of the current instrument, ensuring the detection of ordinary and normal sample tube groups, and ensuring detection efficiency.

[0084] In this embodiment, again refer to Figure 7The expedited processing assembly 300 further includes a first drive motor 301 and a first rotating shaft 305. The first drive motor 301 is disposed on the base 100. The first rotating shaft 305 is connected to the output shaft of the first drive motor 301. One end of the expedited push block 308 is disposed on the first rotating shaft 305. The first drive motor 301 drives the first rotating shaft 305 to rotate, thereby driving the expedited push block 308 to rotate toward the upper feeding platform 103, that is, pushing the sample tube group out of the first conveying track 101. In this embodiment, in order to reduce the swing space of the expedited push block 308, the expedited push block 308 is replaced by two rockers of smaller length, and two first rotating shafts 305 are synchronously driven and share a first drive motor 301 for driving;

[0085] Specifically, a first rotating pulley 302 is arranged on the output shaft of the first driving motor 301, two second rotating pulleys 304 are arranged on one of the first rotating shafts 305, and a third rotating pulley 307 is arranged on the other first rotating shaft 305. The first rotating pulley 302 is connected to one of the second rotating pulleys 304 through a first rotating synchronous belt 303, and the third rotating pulley 307 is connected to the other second rotating pulley 304 through a third synchronous belt 306. By arranging the first rotating pulley 302, two second rotating pulleys 304 and one third rotating pulley 307, synchronous rotation of the two first rotating shafts 305 is achieved, the driving device is reduced, and the swinging space required for the emergency push block 308 is also reduced.

[0086] Optionally, the two first rotating shafts 305 may also be driven separately to ensure the synchronous swinging of the two first rotating shafts 305 .

[0087] Optionally, the emergency push block 308 can also be set as a translation drive structure. For example, the moving path of the emergency push block 308 is a straight line, perpendicular to the conveying route of the first conveying track 101, that is, a linear cylinder drive is adopted, or a guide rail slider structure is combined with a screw nut structure to achieve linear movement, or a guide sleeve guide shaft structure replaces the aforementioned guide rail slider structure.

[0088] In one embodiment, Figure 6 and Figure 8 As shown, the first conveying track 101 includes a first bottom plate 1015, a first side plate 1016, a first synchronous belt 1013, a first driving pulley 1012, a first driven pulley 1014 and a first conveying motor 1011, the first bottom plate 1015 is arranged on the first mounting platform of the base 100, the first side plate 1016 is connected to the first bottom plate 1015 and is perpendicular to each other, wherein the first side plate 1015 is provided with a first limiting rib 10161; the first limiting rib 10161 limits the sample rack to prevent the sample rack from moving in a direction perpendicular to the first bottom plate 1015.

[0089] Furthermore, the first active pulley 1012 and the first driven pulley 1014 are rotatably arranged at the two ends of the first bottom plate 1015 (i.e., the length direction of the first bottom plate 1015), the first synchronous belt 1013 is wound around the first active pulley 1012 and the first driven pulley 1014, and a portion of the first synchronous belt 1013 is close to the first bottom plate 1015, so that the first bottom plate 1015 supports the first synchronous belt 1013, and the sample tube group is placed on the first synchronous belt 1013. In the embodiment, the width of the first synchronous belt 1013 is adapted to the width of the first bottom plate 1015, and sidewall strips 10151 are provided on both sides of the first bottom plate 1015 to form a groove, the first synchronous belt 1013 is located in the groove, the first conveying motor 1011 is provided on the base 100 through a bracket, the first active pulley 1012 is fixedly connected to the output shaft of the first conveying motor 1011, and the first synchronous belt 1013 is driven to rotate by the rotation of the first conveying motor 1011, thereby realizing the transfer and transportation of the sample tube group. It should be noted that in the present embodiment, the first conveying motor 1011 can realize forward and reverse rotation, so as to return the sample tube group that has been conveyed and has not been scanned for sample information to the loading platform 103.

[0090] In one embodiment, the multifunctional sample detection transmission track further includes a first rotating assembly 400, which is used to rotate the sample tube. Since the sample tube is labeled with sample information, when the operator places the sample tube in the sample rack, the direction of the sample information is inconsistent. At this time, the sample tube needs to be rotated to keep the sample information consistent, so as to facilitate information scanning and enter the next step. In this embodiment, the sample information can be a QR code or a bar code.

[0091] Specifically, Fig.12 and Fig.13 As shown, the first rotating assembly 400 includes a first rotating bracket 401 fixedly disposed on the base 100, a first rotating motor 403 disposed on the first rotating bracket 401, and a first main rotating disk 404 disposed on the output shaft of the first rotating motor 403, and the first main rotating disk 404 is driven to rotate by the rotation of the first rotating motor 403;

[0092] The first rotating assembly 400 also includes a second rotating bracket 508, on which two first sub-rotating disks 405 are arranged, and the second rotating bracket 508 is movably arranged on the base 100. For example, the second rotating bracket 508 can approach or move away from the first conveying track 101, and the second rotating bracket 508 and the first rotating bracket 401 are arranged on both sides of the first conveying track 101. By the second rotating bracket 508 approaching or moving away from the first conveying track 101, the two second sub-rotating disks 405 are abutted and fixed to the first main rotating disk 404 on the sample tube, and the sample tube is driven to rotate to the information scanning position by the rotation of the first main rotating disk 404.

[0093] Furthermore, in order to reduce the resistance encountered by the sample tube during rotation, the two second auxiliary rotating disks 405 are rotatably disposed on the second rotating bracket 508 .

[0094] Furthermore, in order to avoid excessive pressure on the sample tube caused by the second auxiliary rotating disk 405 and the first main rotating disk 404 to abut against and fix the sample tube, the two second auxiliary rotating disks 405 are elastically arranged on the second rotating bracket 508. Specifically, two horizontal and parallel second fixing posts 408 are arranged on the second rotating bracket 508, one end of the second fixing post 408 is fixed on the second rotating bracket 508, and a second mounting support 406 movable along the axial direction of the second fixing post 408 is arranged on the two second fixing posts 408, and the two second auxiliary rotating disks 405 are rotatably arranged on the second mounting support 406, and two second buffer springs 407 are also sleeved on the two second fixing posts 408. When the two second auxiliary rotating disks 405 abut against the sample tube, the second buffer springs 407 will be compressed, so that the extrusion force on the sample tube is only the elastic force of the spring, so as to avoid the second auxiliary rotating disk 405 directly and rigidly contacting the sample tube with the first main rotating disk 404, which causes the sample tube to be squeezed or damaged or the sample tube to be subjected to greater resistance when rotating.

[0095] In one embodiment, a scanner 402 is also fixed on the first rotating bracket 401. The scanner 402 is used to scan the sample information on the sample tube. When the sample information on the sample tube is not in the scanning position, the first main rotating disk 404 rotates to drive the sample tube to rotate to the scanning position, so that the scanner 402 completes scanning the sample information. In this embodiment, the scanner 402 is a prior art and will not be described in detail.

[0096] In one embodiment, the multifunctional sample detection transmission track also includes a sampling fixing assembly 500 that moves relative to the base 100, and the sampling positioning assembly 500 includes a sampling limiter 5083 and a sampling baffle 509, wherein the sampling baffle 509 and the sampling limiter 5083 are arranged on the same track, and the sampling limiter 5083 is arranged on the second rotating bracket 508, wherein the sampling limiter 5083 and the sampling baffle 509 can move toward or away from each other synchronously. By setting the sampling baffle 509, the sampling baffle 509 can be moved to position the sampling tubes on the sample tube group and to be located on the same straight line. In combination with the sampling stopper 5083, one of the sampling tubes in the sample tube group can be positioned and fixed, so that the rubber stopper of the sample tube is located below the sampling positioner 5083, and the sampling needle passes through the sampling positioner 5083 and penetrates into the sample tube for sampling. When the sampling needle exits the sample tube, the sampling positioner 5083 upper limits the rubber stopper in the axial direction of the sample tube to prevent the sampling needle from driving the rubber stopper out of the sample tube. In this embodiment, the sampling stopper 5083 is provided with a U-shaped fixing groove, and the size of the U-shaped fixing groove is adapted to the outer diameter of the sampling tube.

[0097] Furthermore, in order to prevent the sampling stopper 5083 from having a rigid contact with the sample tube when sampling the sample tube, the sampling stopper 5083 is movably arranged on the second rotating bracket 508. Specifically, a first linear guide 5081 is arranged on the second rotating bracket 508, a first slider 5082 is arranged on the first linear guide 5081, and the sampling stopper 5083 is arranged on the first slider 5082.

When the sampling stopper 5083 is engaged and positioned with the sample tube, the force applied by the sampling stopper 5083 to the sample tube is only the elastic force of the tension spring, so that the sampling stopper 5083 and the second rotating bracket 508 are elastically connected. Furthermore, a first buffer spring 5102 is arranged between the second connecting block and the sampling bracket, one end of the first buffer spring 5102 abuts against the second connecting block 5101, and the other end thereof is fixedly connected to the sampling bracket 501. When the sampling baffle 509 moves toward the sampling limiter 5083, the second buffer spring 5102 is compressed, further ensuring the elastic abutment of the sampling baffle 509 against the sample tube.

At this time, the first lifting rod 2101 moves up, and the first sampling needle 2103 is reset under the action of the first spring 210214. The first sampling needle 2103 is repositioned for puncture sampling. It should be pointed out that the resistance of the rubber stopper to the first sampling needle 2103 is much smaller than the elastic force applied to the first sampling needle 2103 by the first spring 210214, so that the first sampling needle 2103 can puncture and sample smoothly.

The length direction of the first limiting boss 21043 is consistent with the axis of the first lifting rod 2101, and the first limiting groove 21011 and the first limiting boss 21043 are adapted in shape. The first limiting boss 21043 is clamped in the first limiting groove 21011, wherein the distance moved by the first limiting boss 21043 in the first limiting groove 21011 is not less than the moving distance required for the first sampling needle 2103 to take samples, thereby ensuring that the first limiting boss 21043 will not separate from the first limiting groove 21011.

[0128] Optionally, a first limiting groove 21011 may be provided on the first lifting rod 2101, and a first limiting boss 21043 may be provided in the first channel.

It should be noted that the second lifting assembly has the same structure as the first lifting assembly, and the second rotating assembly has the same structure as the first rotating assembly, which will not be described in detail here. Due to the tight structure, in order to make way, the second arm 2202 is bent to ensure that the second sampling needle 2203 does not touch the first lifting rod 2101 when adding samples.

[0133] In one embodiment, in the second reference Figure 1 and Figure 2 The sample tray 1600 is rotatably disposed on the support platform, and a plurality of first mounting positions are arranged on the sample tray 1600.

The main purpose of its design is to flexibly handle the gradient dilution of samples without affecting the main timing of the reaction unit, and to be able to store cups for retesting samples. When gradient dilution is required, the sample tray is rotated to mix the sample that is first dripped into the dilution cup, and then the sample after the first dilution is aspirated and dripped into the adjacent dilution cup.

In this embodiment, there are multiple first annular boss 170041, first annular support groove 170021, second annular support groove and second annular boss. By adopting this convex-concave structure, the sample plate 1600 can be kept warm to avoid direct heat interaction and heat loss.

[0135] Furthermore, it also includes a reagent tray 1700 rotatably arranged on the support platform. The reagent tray 1700 is rotatably arranged on the support platform like the sample tray 1600.

In the present application, the rotation radius of the sample tray 1600 is set to be larger than the rotation radius of the reagent tray 1700, thereby achieving the setting of the reagent tray 1700 on the inner circle of the sample tray 1600.

[0136] Furthermore, a rotating assembly is also included for rotating the sample disk 1600 and the reagent disk 1700. The rotating assembly includes a first support cylinder 16003 fixedly arranged on the support platform, a first rotating rod 16001 and a first rotating sleeve 17001, and the three are arranged coaxially.

The ISE electrolyte module 1200 is used for electrolyte analysis and detection of samples; by setting the ISE electrolyte module 1200, the function of realizing electrolyte detection on the same detection instrument is solved. After the second sampling needle 2203 obtains the instruction for electrolyte detection through the pre-sample information, it samples the sample to be detected and adds it to the ISE electrolyte module 1200 for analysis. At the same time, when the system obtains other samples that need to detect other biochemical or protein items, the first sampling needle 2103 of another group simultaneously performs the sampling and adding actions of other samples, and other biochemical or protein detection items use another set of reaction systems. Therefore, the detection efficiency of clinical projects is greatly improved, so on the basis of the original constant speed of 400 tests / hour for biochemical or protein detection, the detection efficiency is further improved. After counting the electrolyte detection items, the overall detection speed of the detection instrument reaches 800 tests / hour.

[0142] The dual-light path detection module is arranged on the supporting platform and is used for optical detection of the reaction cup on the reaction disk 1400.
