Description

Technical Field

[0001] This utility model belongs to the field of medical testing technology, and in particular refers to a comprehensive, multi-item automated specific protein analyzer. Background Technology

[0002] Fully automated specific protein analyzers are common instruments in the medical testing field. They are typically used to perform various tests on human samples such as whole blood, serum, plasma, peripheral blood, urine, cerebrospinal fluid, and fecal lysate. Before testing, the sample is usually placed in a sample tube and automatically transported to the instrument via its track.

[0003] To meet the diverse testing and storage needs of different samples, current mainstream biochemical analyses employ single-optical-module analysis, which cannot fully cover the detection of specific proteins and other items. Furthermore, mainstream specific protein analyzers cannot cover all biochemical testing items. Additionally, current biochemical analyzers lack puncture sampling capabilities, and specific protein analyzers do not support testing of other sample types such as urine and stool, nor do they possess ISE electrolyte detection capabilities. Moreover, neither of the two currently available analyzers offers independent sample dilution and retesting functions.

[0004] Furthermore, neither of the two analyzers mentioned above has the capability to connect with mainstream urine analyzers, thus reducing the efficiency of clinical testing and increasing the risk of sample contamination. Utility Model Content

[0077] ​The application will be described in further detail below with reference to the accompanying drawings. In the description of the embodiments, unless otherwise specified, the terms "left", "right", and the like indicate the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the application and simplify the description, and do not indicate or imply that the application must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0078] As Figure 1 and Figure 2 shown, the utility model provides a kind of comprehensive multi-project detection's automated specific protein analyzer, mainly including support platform, online conveying track 1100, urgent processing component, double sample arm sampling mechanism 2000, sample disc 1600, reagent disc 1700, reaction disc 1400, first reagent arm 1500, ISE electrolyte module 1200 and double optical path detection module.

[0079] Online conveying track 1100 includes base 100, first conveying track 101, second conveying track 102, feeding platform 103 and discharging platform 104, wherein the first conveying track 101 is arranged close to the side of the support platform, 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 consistent conveying directions, the feeding platform 103 and the discharging platform 104 are arranged between the first conveying track 101 and the second conveying track 102, the feeding platform 103 is used for the transmission and placement of sample tubes for current instrument detection, the discharging 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 for current instrument detection, and the second conveying track 102 is used for the transmission of samples between adjacent two detection instruments.

[0080] Specifically, as Figures 5-6 shown, the online conveying track 1100 is arranged on the support platform, which mainly includes a base 100, a first mounting platform is arranged on the base 100; a first conveying track 101 is arranged on the first mounting platform of the base 100, in the 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 transmission components, and the first conveying track 101 is used for the transmission of sample tube groups to be detected by the current detection instrument; in the embodiment, the sample tube group includes a sample holder and a plurality of sampling tubes arranged on the sample holder.

[0081] The loading platform 103 is arranged on one side of the first conveying track 101. The loading platform 103 is in communication with the first conveying track 101, that is, the sample tube group to be detected 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 before sampling and detection of the current detection instrument. 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 capable of reciprocating is arranged above the loading platform 103. As shown in Figure 5 and Figure 9 The first pushing block 1058 pushes the sample tube group to the first conveying track 101. In the embodiment, the moving direction of the first pushing block 1058 is perpendicular to the conveying direction of the first conveying track 101. In the embodiment, in order to facilitate the linear movement of the sample tube group during the movement of the sample tube group to the first conveying track 101, the width of the loading platform 103 and the length of the sample rack of the sample tube group are matched. Meanwhile, a loading limiting edge is arranged on the side of the loading platform 103 to avoid the movement of the sample rack in the direction perpendicular to the loading platform 103. In the embodiment, a first trigger switch 1071 is arranged on one side of the first conveying track 101. As shown in Figure 16 When the sample tube group touches the first trigger switch 1071, the first conveying track 101 starts to convey the sample.

[0082] 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 in communication with 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 temporarily storing and placing the sample tube group after sampling or transferring to the next detection instrument. A second pushing block 601 capable of reciprocating linearly is arranged above the first conveying track 101. As shown in Figure 6 and Figure 19 The second pushing block 601 can push the sample tube group on the first conveying track 101 to the unloading platform 104. In the embodiment, the moving path of the second pushing block 601 is perpendicular to the conveying path of the first conveying track 101. In the embodiment, in order to facilitate the linear movement of the sample tube group during the movement of the sample tube group from the first conveying track 101 to the unloading platform 104, the width of the unloading platform 104 and the length of the sample rack of the sample tube group are matched. Meanwhile, an unloading limiting edge is arranged on the side of the unloading platform 104 to avoid the movement of the sample rack in the direction perpendicular to the unloading platform 104. In the embodiment, a second trigger switch 1072 is arranged on the first conveying track 101. As shown in Figure 18As shown, when the sample tube group after sampling touches the second trigger switch 1072, the first conveying track 101 stops sample conveying, and the second pushing block 601 pushes the sample tube group on the first conveying track 101 to the discharging platform 104. The first trigger switch 1071 and the second trigger switch 1072 are both prior art, equivalent to position detection devices, and will not be described in detail here.

[0083] The urgent processing assembly 300 is arranged on the other side of the first conveying track 101 and corresponds to the position of the feeding platform 103. The urgent processing assembly 300 is provided with an urgent pushing block 308 that moves back and forth, as shown in Figure 6 and Figure 11 As shown, when urgent sampling detection is needed, the urgent pushing block 308 will push the sample tube group that is not in the sampling program and is currently located on the first conveying track 101 back to the feeding platform 103, so that the first conveying track 101 leaves a preset space for the operator to place the urgent sample tube group on the first conveying track 101 to enter the next sampling detection process.

[0084] The application sets the urgent processing assembly 300 on the opposite side of the feeding platform 103 of the first conveying track 101, and sets the urgent pushing block 308 that moves back and forth in the urgent processing assembly 300. The placement space of the urgent sample tube group is reserved on the first conveying track 101 through the movement of the urgent pushing block 308, so that the urgent processing of the sample can be realized on the same detection instrument, without the need for an additional separate urgent sample detection instrument, reducing the equipment cost of the detection mechanism, and at the same time, without disturbing the original detection order of the current instrument, ensuring the detection of ordinary normal sample tube groups and ensuring the detection efficiency.

[0085] In this embodiment, referring again to Figure 7 The urgent processing assembly 300 further includes a first driving motor 301 and a first rotating shaft 305. The first driving motor 301 is arranged on the base 100, the first rotating shaft 305 is connected with the output shaft of the first driving motor 301, one end of the urgent pushing block 308 is arranged on the first rotating shaft 305, the first driving motor 301 drives the first rotating shaft 305 to rotate, and in turn drives the urgent pushing block 308 to rotate to the side of the feeding platform 103, that is, to push the sample tube group away from the first conveying track 101. In this embodiment, in order to reduce the swing space of the urgent pushing block 308, two small-length rocker arms are used to replace the urgent pushing block 308, and two first rotating shafts 305 are used to drive synchronously and share one first driving motor 301 for driving;

[0086] Specifically, the 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 the third rotating pulley 307 is arranged on the other first rotating shaft 305. The first rotating pulley 302 is connected with one of the second rotating pulleys 304 through the first rotating synchronous belt 303, and the third rotating pulley 307 is connected with the other second rotating pulley 304 through the third synchronous belt 306. By arranging the first rotating pulley 302, the two second rotating pulleys 304, and the third rotating pulley 307, synchronous rotation of the two first rotating shafts 305 is achieved, the driving device is reduced, and the swing space required by the urgent pushing block 308 is also reduced.

[0087] Alternatively, the two first rotating shafts 305 can also be driven separately to ensure synchronous swing of the two first rotating shafts 305.

[0088] Alternatively, the urgent pushing block 308 can also be arranged in a translational driving structure. For example, the moving path of the urgent pushing block 308 is a straight line perpendicular to the conveying route of the first conveying track 101, that is, a straight-line air cylinder is used for driving, or a guide rail sliding block structure is combined with a screw nut structure to realize linear movement, or a guide sleeve guide shaft structure is used to replace the foregoing guide rail sliding block structure.

[0089] In one embodiment, as shown in Figure 6 and Figure 8 , 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, and the first side plate 1016 is connected with the first bottom plate 1015 and perpendicular to each other. The first side plate 1015 is provided with a first limiting baffle 10161. The first limiting baffle 10161 limits the sample rack to avoid movement of the sample rack in the direction perpendicular to the first bottom plate 1015.

[0090] Further, the first driving pulley 1012 and the first driven pulley 1014 are respectively arranged at 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 arranged around the first driving pulley 1012 and the first driven pulley 1014, and part of the first synchronous belt 1013 is arranged above the first bottom plate 1015 to support the first synchronous belt 1013, so that 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 the first synchronous belt 1013 is arranged in the groove formed by the side limiting strips 10151 arranged on both sides of the first bottom plate 1015. The first conveying motor 1011 is arranged on the base 100 through a support, the first driving pulley 1012 is fixedly connected with 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, so as to realize the transfer and transportation of the sample tube group. It should be noted that in the embodiment, the first conveying motor 1011 can realize forward and reverse rotation, so as to return the sample tube group which has been conveyed and has not been scanned to the sample information to the feeding platform 103.

[0091] In one embodiment, the multifunctional sample detection transmission track further comprises a first rotating assembly 400 for rotating the sample tube. Since the sample information is attached to the sample tube, when the operator places the sample tube on the sample holder, the directions of the sample information are inconsistent. At this time, the sample tube needs to be rotated to keep the direction of the sample information consistent, so as to facilitate the information scanning to enter the next step. In the embodiment, the sample information can be a two-dimensional code or a bar code.

[0092] Specifically, as shown in Figure 12 and Figure 13 , the first rotating assembly 400 comprises a first rotating support 401 fixedly arranged on the base 100, a first rotating motor 403 arranged on the first rotating support 401, and a first main rotating disc 404 arranged on the output shaft of the first rotating motor 403, and the first main rotating disc 404 is driven to rotate by the rotation of the first rotating motor 403.

[0118] Further, in order to facilitate the assembly between the first cleaning bin 21041 and the first sampling needle 2103, the first sealing block 2104111 is arranged on the first cleaning bin 21041, the first sealing block 2104111 seals the first cleaning bin 21041, thereby forming a sealed first cleaning cavity 2104121.
