Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a sorting tray mechanism. Background Art

[0002] Clinical testing institutions are faced with an increasing number of vacuum blood collection tubes that need to be processed daily. The vacuum blood collection tube sample sorting system is designed to replace traditional manual operations and automate sample collection and sorting. The loader in the sorting system organizes the scattered and mixed vacuum blood collection tubes into orderly, independent tubes, facilitating the sorting system's subsequent automated classification and advanced processing (such as cannulation and inserting the tubes into the corresponding centrifuge block trays and sample trays / sample racks supported by various analyzers).

[0003] At present, the traditional high-speed blood collection tube sample sorting machine with intubation function uses two relatively independent sorting systems (loader + scanner + conveyor track + robot) to complete the sorting work. This structural layout of the sorting system causes the vacuum blood collection tubes originally mixed together on the client to be diverted into two independent loaders. Due to the limitations of the respective range of movement of the two sets of robots, a large number of vacuum blood collection tubes need to be transferred twice before they can be sorted into the appropriate sorting channel. Therefore, the traditional sorting system has the disadvantages of low efficiency, high failure rate and high cost.

[0004] In addition, traditional sorting machines generally scan the barcode of vacuum blood collection tubes at the loader position. After the scan is completed, the information is sent to the hospital's laboratory information system to query the test items of the blood collection tube to determine the final sorting channel of the blood collection tube. In reality, due to the busy hospital network, the time for the sorting machine to obtain the test item information of the blood collection tube is often irregular, and sometimes the time is relatively long. In this case, the blood collection tube stays around the loader component, blocking the subsequent loading of blood collection tubes, causing the entire sorting system to be suspended, seriously affecting the sorting efficiency.

[0034] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0035] A sorting tray mechanism according to an embodiment of the present application, such as Figures 1-6 As shown, it comprises: a support portion 1, the support portion 1 comprising a base 11 and a mounting plate 12 located above the base 11; the mounting plate 12 is connected to a top plate 14 via a plurality of connecting columns 13;

[0036] The rotating unit 2 is connected to the support part 1; the rotating unit 2 includes a rotating power part 21, a rotating support part 22 and a rotating disk 23, the rotating power part 21 is connected to the base 11; the rotating support part 22 is detachably connected to the base 11; the rotating support part 22 is rotatably connected to a sleeve part 24 through a rotating part. As an example, the rotating part is a bearing, and the upper and lower ends of the sleeve part 24 are respectively connected to the rotating support part 22 through bearings; the rotating disk 23 is connected to the upper end of the sleeve part 24, and a passive connecting part 241 is formed on the outer wall of the sleeve part 24. As an example, the passive connecting part 241 is an annular tooth groove; the rotating power part 21 is a motor with an encoder, which is a prior art and will not be repeated here; the output end of the rotating power part 21 cooperates with the sleeve part 24, and the rotating power part 21 works. The sleeve member 24 is driven to rotate, thereby realizing the rotation of the rotating disk 23; the output end of the rotating power unit 21 is connected to an active connecting member 211, and the active connecting member 211 is used in conjunction with the passive connecting member 241. As an example, the passive connecting member 241 is an annular tooth groove, and the active connecting member 211 is a driving gear that cooperates with the annular tooth groove. In order to facilitate the layout of the structure, the driving gear and the annular tooth groove are connected by a synchronous belt 242 to realize the transmission between the driving gear and the annular tooth groove; the rotating disk 23 is located on the inner side of the mounting plate 12, and the rotating disk 23 is located below the top plate 14; there is a preset gap between the rotating disk 23 and the mounting plate 12, so that the mounting plate 12 does not interfere with the rotation of the rotating disk 23; the mounting plate 12 also serves as a limiter for the blood collection tube 3, so that the corresponding blood collection tube 3 will not fall out of the matching groove 231;

[0037] The rotating disk 23 is circular, and its edge is formed with a plurality of spaced-apart matching grooves 231 adapted to fit the blood collection tubes 3. The notches of the matching grooves 231 are chamfered to facilitate the insertion of the blood collection tubes 3 into the corresponding matching grooves 231. The caps of the blood collection tubes 3 that have entered the matching grooves 231 are positioned above the matching grooves 231. The caps of the blood collection tubes 3 are larger than the matching grooves 231, thereby preventing the blood collection tubes 3 from falling out of the matching grooves 231.

[0038] The mounting plate 12 of the support portion 1 is provided with an introduction slide 121 and at least one track distribution slide 122. When there are two or more track distribution slides 122, the two or more track distribution slides 122 are arranged at intervals; the introduction slide 121 serves as a channel for delivering the blood collection tube 3 into the corresponding matching groove 231, and the track distribution slide 122 serves as a channel for pushing the blood collection tube 3 out of the corresponding matching groove 231. In this embodiment, there are two track distribution slides 122, so that different blood collection tubes 3 enter the preset track distribution slide 122 to enter the next process; the introduction slide 121 The outlet end is higher than the upper surface of the notch of the matching groove 231, so that the blood collection tube 3 entering from the introduction slide 121 can directly reach the corresponding matching groove 231; the inlet end of the track distribution slide 122 is lower than the upper surface of the notch of the matching groove 231, or the inlet end of the track distribution slide 122 is flush with the upper surface of the notch of the matching groove 231, so that the blood collection tube 3 can enter the track distribution slide 122 conveniently; a buffer block 15 is provided on the top plate 14 or the mounting plate 12 of the support part 1, and the buffer block 15 is located directly opposite the introduction slide 121, and is used for auxiliary guidance of the blood collection tube 3 into the corresponding matching groove 231.

[0039] It also includes a tube pushing unit 4, which is connected to the top plate 14 of the support part 1. The tube pushing unit 4 pushes the corresponding blood collection tube 3 from the matching groove 231 to the corresponding track distribution slide 122, and the corresponding blood collection tube 3 enters the corresponding process from the corresponding track distribution slide 122; one track distribution slide 122 corresponds to one tube pushing unit 4.

[0040] In one embodiment, if Figure 1 and Figure 6 As shown, the tube pushing unit 4 includes a push-pull power part 41 connected to the top plate 14 of the support part 1. The push-pull power part 41 is an electric telescopic rod, which is a prior art and will not be described here in detail. The movable end of the push-pull power part 41 is connected to a push rod 42. When the movable end of the push-pull power part 41 is in the extended state, the push rod 42 is located directly opposite the entrance end of the corresponding track distribution slide 122 and is located behind the blood collection tube 3, which makes it convenient to push the corresponding blood collection tube 3 into the corresponding track distribution slide 122.

[0041] In one embodiment, if Figure 6 As shown, the push tube unit 4 also includes a mounting support plate 43, and the push-pull power part 41 is connected to the top plate 14 of the support part 1 through the mounting support plate 43. The mounting support plate 43 is provided with a clearance groove 44, and the push rod 42 moves in the clearance groove 44.

[0042] Since the orientation of the barcode information surface is random and uncertain when the blood collection tube enters the rotating disk, the blood collection tube needs to be rotated axially to ensure that the barcode information can be completely read by the scanner. Figure 1 、 Figure 7 and Figure 8 As shown, a first blood sampling tube rotation drive unit 5 is designed, which includes a rotation drive unit 51 provided on the rotation support member 22 of the support portion 1. The rotation drive unit 51 is a rotary motor, which is a prior art and will not be described in detail here; the rotation drive unit 51 is connected to the rotation support member 22 through a connecting plate 52; the rotation drive unit 51 is located on the inner side of the blood sampling tube 3, and the movable end of the rotation drive unit 51 is connected to a rotating roller 53 for driving the blood sampling tube 3 to rotate axially; the blood sampling tube is driven to rotate by the rotational force so that the code scanner can scan the code on the blood sampling tube; a rubber material with greater friction may be provided on the rotating roller to increase the friction between the blood sampling tube and the rotating roller to ensure the stability of the blood sampling tube during rotation.

[0043] The first blood sampling tube rotation drive unit 5 further includes a first auxiliary rotating wheel 54 and a second auxiliary rotating wheel 55 which are spaced apart and are rotatably connected to the mounting plate 12 of the support portion 1. The rotating roller 53, the first auxiliary rotating wheel 54 and the second auxiliary rotating wheel 55 cooperate to form a rotating space for axially rotating the blood sampling tube 3. When the blood sampling tube 3 enters the rotating space, the blood sampling tube is driven to rotate so that the code on the blood sampling tube can be scanned by the code scanner. It should be noted that when the code position is within a reasonable range, it is not rotated.

[0044] In order to make the first blood collection tube rotation driving unit 5 more convenient during operation, the front and rear sides of the matching groove 231 of the rotating disk 23 are formed with a clearance space, such as Figure 7 As shown, the wall of the blood sampling tube 3 located in the matching groove 231 is exposed outside the matching groove 231. Since the blood sampling tube 3 is connected to the upper surface of the matching groove 231 through its tube cap, the relative connection of the blood sampling tube 3 is achieved. The clearance does not affect the position of the blood sampling tube 3 in the matching groove 231. The clearance allows the rotating roller 53, the first auxiliary rotating wheel 54 and the second auxiliary rotating wheel 55 to cooperate with the wall of the blood sampling tube 3, thereby facilitating rotation.

[0045] Further, if Figure 8 As shown, it also includes a linkage plate 56, and the first auxiliary rotating wheel 54 and the second auxiliary rotating wheel 55 are rotatably connected to the linkage plate 56 respectively; the mounting plate 12 is connected to a fixing seat 57, and the fixing seat 57 is connected to at least two guide rods 58, which have good stability. The linkage plate 56 is movably penetrated on the guide rod 58, and the guide rod 58 is penetrated by an elastic member 59, which is a spring. The elastic member 59 is located between the linkage plate 56 and the fixing seat 57. The elastic member 59 squeezes the linkage plate 56 to make the first auxiliary rotating wheel 54 and the second auxiliary rotating wheel 55 fit the outer wall of the blood collection tube 3.

[0046] In one embodiment, if Figure 3 、 Figure 4 and Figure 9 As shown, it also includes a blood collection tube height judgment unit 6, which includes a connecting frame 61, and the connecting frame 61 is connected to the base 11 of the support part 1; three sensors 62 are arranged at intervals on the connecting frame 61, and the distances of the three sensors 62 relative to the base 11 are different. The sensor 62 is used to sense whether there is a blood collection tube 3 on the corresponding matching slot 231, or to judge the height specification of the blood collection tube 3 under the corresponding matching slot 231; based on the sensor signal, it can be judged whether there is a blood collection tube or the specification of the blood collection tube, so as to allocate the final sorting destination of the blood collection tube. It should be noted that the structure and working principle of the sensor 62 are existing technologies and will not be repeated here; for example: the positions of the centrifugal block trays of different detection devices are different, and there are certain restrictions on the height of the inserted blood collection tubes to be tested. Generally speaking, blood collection tubes of different heights cannot be mixed and inserted into the centrifugal block tray of the same detection device.

[0047] In one embodiment, if Figure 1 As shown, it also includes a scanning unit 7, which includes a mounting frame 71. The mounting frame 71 is connected to the top plate 14 of the support part 1. The mounting frame 71 is connected to a scanner 72. After the blood collection tube height judgment unit 6 determines that the blood collection tube 3 is a blood collection tube, the scanner 72 reads the information on the blood collection tube 3 and determines which track distribution slide 122 the blood collection tube 3 enters. It should be noted that the structure and working principle of the scanner 72 are existing technologies and will not be repeated here.

[0048] In one embodiment, if Figure 1 and Figure 8 As shown, it also includes a coding rotation drive unit 8, which is used to print the corresponding code on the blood collection tube 3 to help personnel of clinical testing institutions quickly identify the ownership and serial number of the test tube. It should be noted that the composition of the code and the corresponding information are existing technologies and will not be repeated here; the coding rotation drive unit 8 is arranged on the rotating support 22 of the support part 1, and the coding rotation drive unit 8 includes a coder and a second blood collection tube rotation drive unit. The structure of the second blood collection tube rotation drive unit is the same as that of the first blood collection tube rotation drive unit 5, but the position is different. The second blood collection tube rotation drive unit rotates the blood collection tube axially, and the coder prints the corresponding code on the surface of the blood collection tube. It should be noted that the structure and working principle of the coder are existing technologies and will not be repeated here.

[0049] After the blood collection tube height judgment unit determines the blood collection tube, the scanning unit 7 starts working, reads the information on the blood collection tube and ultimately determines which track distribution slide 122 the blood collection tube enters; according to the information determined by the scanning device, the blood collection tube is pushed into the corresponding track distribution slide 122 through the tube pushing unit 4.

[0050] The function of the sorting disk of this embodiment is to introduce mixed sample blood collection tubes into the slide 121, and drive the rotating disk 23 with sixteen stations to rotate periodically through the rotating unit 2 composed of a motor with an encoder. At the corresponding positions, there are respectively designed structures such as blood collection tube height judgment, blood collection tube barcode scanner, inkjet printer, and track distribution slide set as needed. In addition, blood collection tube rotation drive, tube pushing and other mechanisms are respectively designed at the scanning, inkjet printing and each track channel position, so as to realize the accurate and orderly actions of blood collection tube height judgment, scanning, inkjet printing and track distribution, and complete the sorting of samples.

[0051] The multifunctional sorting tray of the utility model realizes the pre-sorting function of vacuum blood collection tubes in the sorting system, and can serve the physical steering distribution channels at various angular positions at the back end; the blood collection tubes can be sorted into one, two, or multiple sorting channels at different angular positions at the same time; the sorting tray provides multiple test tube buffer positions after scanning the barcodes of the blood collection tubes. When sending information to the hospital's laboratory information system to obtain the test items of the blood collection tubes to determine the sorting channels, the sorting tray can still keep rotating and continue the subsequent scanning of the blood collection tubes, and the total sorting processing time will not be affected by the time difference of the network query waiting time, thereby ensuring the high-efficiency operation of the sorting system; one or more structures with rotating test tubes and inkjet printing functions are set on the sorting tray; and with a high and low tube recognition sensor, the final distribution track of the blood collection tubes can be allocated in advance to avoid blood collection tubes of different heights being inserted into the same centrifugal block tray.
