Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a sorting plate for pre-sorting blood collection tubes. Background Art

[0002] With the aging of the population and the continuous improvement of people's living standards, the number of vacuum blood collection tubes that clinical testing institutions need to handle every day is increasing. The use of vacuum blood collection tube sample sorting system is to replace the traditional manual operation and realize the functions of automatic sample collection and sorting. Among them, the loader in the sorting system is to sort out the various vacuum blood collection tubes scattered and mixed together, and turn them into orderly and independent vacuum blood collection tubes one by one, which is convenient for the sorting system to carry out subsequent automatic classification and advanced processing (such as intubation, inserting the blood collection tube into the corresponding centrifugal block tray, sample tray / sample rack supported by each analyzer);

[0003] At present, the traditional high-speed blood collection tube sample sorting machine with cannulation function adopts two relatively independent sorting systems (loader + scanner + conveyor track + robot) to complete the sorting work. This structural layout of the sorting system makes the vacuum blood collection tubes originally mixed together on the client be diverted into two independent loaders. Due to the limitation of the activity range 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 the vacuum blood collection tube at the position of the loader. 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, it often happens that due to the busy hospital network, the time for the sorting machine to obtain the test item information of the blood collection tube is not fixed, and sometimes the time is relatively long. In this case, the blood collection tube stays around the loader component, blocking the subsequent loading of the blood collection tube, and the entire sorting system is in a suspended state, which seriously affects the sorting efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] An embodiment of the present application provides a sorting tray for pre-sorting blood collection tubes, such as Figure 1-Figure 6 As shown, it comprises: a support portion 1, the support portion 1 comprises 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 member 22 and a rotating disk 23, the rotating power part 21 is connected to the base 11; the rotating support member 22 is detachably connected to the base 11; the rotating support member 22 is rotatably connected to a sleeve member 24 through a rotating part, as an example, the rotating part is a bearing, and the upper and lower ends of the sleeve member 24 are respectively connected to the rotating support member 22 through bearings; the rotating disk 23 is connected to the upper end of the sleeve member 24, and a passive connecting member 241 is formed on the outer wall of the sleeve member 24, as an example, the passive connecting member 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 member 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 a passive connecting member 241. As an example, the passive connecting member 241 is an annular tooth groove, and the active connecting member 211 is an active gear matched with the annular tooth groove. In order to facilitate the layout of the structure, the active gear and the annular tooth groove are connected by a synchronous belt 242 to realize the transmission between the active 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 a plurality of matching grooves 231 are formed on its edge, which are arranged at intervals and are adapted to the blood collection tube 3. The notches of the matching grooves 231 are chamfered to facilitate the blood collection tube 3 to enter the corresponding matching grooves 231. The tube cap of the blood collection tube 3 entering the matching grooves 231 is located above the matching grooves 231. The size of the tube cap of the blood collection tube 3 is larger than the size of the matching grooves 231, so that the blood collection tube 3 will not fall from 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 sampling 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 sampling 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 to the introduction slide 121, and is used for auxiliary guidance of the blood sampling tube 3 entering 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, and the push-pull power part 41 is an electric telescopic rod, which is a prior art and will not be described here; the movable end of the push-pull power part 41 is connected to a push rod 42, and the movable end of the push-pull power part 41 is in an extended state, and the push rod 42 is located directly opposite to the entrance end of the corresponding track distribution slide 122, and is located behind the blood collection tube 3, so as to facilitate pushing 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 driving unit 5 is designed, and the first blood sampling tube rotation driving unit 5 includes a rotation driving part 51 arranged on the rotation support member 22 of the support part 1, and the rotation driving part 51 is a rotation motor, which is a prior art and is not described here; the rotation driving part 51 is connected to the rotation support member 22 through a connecting plate 52; the rotation driving part 51 is located on the inner side of the blood sampling tube 3, and the movable end of the rotation driving part 51 is connected to a rotating roller 53, which is used to drive 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 arranged 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 driving unit 5 also includes a first auxiliary rotating wheel 54 and a second auxiliary rotating wheel 55 which are arranged at intervals. The first auxiliary rotating wheel 54 and the second auxiliary rotating wheel 55 are respectively rotatably connected to the mounting plate 12 of the support part 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 scanner can scan the code on the blood sampling tube. It should be noted that when the code position is within a reasonable range, it will not be 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 tube 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 realized. The clearance space does not affect the position of the blood sampling tube 3 in the matching groove 231. The clearance space enables the rotating roller 53, the first auxiliary rotating wheel 54 and the second auxiliary rotating wheel 55 to cooperate with the tube wall of the blood sampling tube 3 for easy rotation.

[0045] Furthermore, 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 at least two guide rods 58 are connected to the fixing seat 57, which has good stability. The linkage plate 56 is movably penetrated on the guide rod 58, and an elastic member 59 is penetrated on the guide rod 58. The elastic member 59 is a spring, and 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 Fig. 9 As shown, it also includes a blood collection tube height judgment unit 6, and the blood collection tube height judgment unit 6 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 on the connecting frame 61 at intervals, and the distances of the three sensors 62 relative to the base 11 are all different. The sensor 62 is used to sense whether there is a blood collection tube 3 on the corresponding matching groove 231, or to judge the height specification of the blood collection tube 3 under the corresponding matching groove 231; according to the signal of the sensor, 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 detected. Generally speaking, blood collection tubes with 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, and the scanning unit 7 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 sampling tube height judgment unit 6 determines that the blood sampling tube 3 is a blood sampling tube, the scanner 72 reads the information on the blood sampling tube 3 and determines which track distribution slide 122 the blood sampling tube 3 enters. It should be noted that the structure and working principle of the scanner 72 are prior art 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 the personnel of the clinical testing institution 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 prior art 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 axially rotates the blood collection tube, 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 prior art 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 to work, 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 mix the sample blood collection tubes through the introduction 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. The corresponding positions are respectively designed with structures such as blood collection tube height judgment, blood collection tube barcode scanner, inkjet printing, and track distribution slides set according to needs, and 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 present invention realizes the pre-sorting function of the vacuum blood collection tube in the sorting system, and can serve the physical turning distribution channels at various angles and positions of the back end; the blood collection tubes can be sorted into one, two, or multiple sorting channels at different angles and positions at the same time; the sorting tray provides multiple test tube buffer positions after scanning the barcodes of the blood collection tubes, and when sending information to the laboratory information system of the hospital to obtain the detection items of the blood collection tubes to determine the sorting channels, the sorting tray can still keep rotating and continue the subsequent scanning action 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; on the sorting tray, one or more structures with rotating test tubes and inkjet printing functions are arranged; with a high and low tube identification sensor, the final distribution track of the blood collection tubes can be allocated in advance, and blood collection tubes of different heights are prevented from being inserted into the same centrifugal block tray.
