Description

Technical Field

[0001] The present invention relates to the technical field of in vitro diagnostic medical devices, and particularly to a large-capacity fully automatic sample handover method and handover system. Background Art

[0002] Generally, when blood collection personnel collect samples and return to the laboratory for handover, it is usually in the evening or at night. At this time, the laboratory staff often get off work and leave the laboratory, and the blood collection personnel cannot enter the laboratory for sample handover. Moreover, if the blood collection personnel enter the laboratory for sample handover, it will increase the risk of cross-contamination. Therefore, to ensure the quality of blood, the current operation of many blood stations is to store the samples in a refrigerator for refrigeration. However, there are two problems with this direct refrigeration: one is that the quality of the samples collected on the same day cannot be identified in time, and the other is that the workload of taking out the samples for experiments the next day is very large, and it is difficult to obtain test results in time when the number of samples is large.

[0003] Currently, due to the large blood collection volume of some blood station users, many blood collection points, and a huge number of samples, the handover time is relatively long, and it is not convenient enough to complete the handover and identification and classification of all samples on site. Therefore, it is still necessary to develop a large-capacity fully automatic sample handover method and handover system for blood collection personnel to quickly hand over the samples to a refrigerated refrigerator, and then the corresponding institution automatically scans, identifies, classifies, and refrigerates the samples. Summary of the Invention

[0004] Based on this, it is necessary to provide a large-capacity fully automatic sample handover method and handover system, which can realize the handover of large-capacity samples, automatically scan, identify, classify, and refrigerate the samples after the sample handover is completed, can shorten the handover time of large-capacity samples, reduce the workload of staff, improve the intelligent level of sample handover processing, and improve the handover work efficiency.

Detailed implementation manners

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0035] As Figures 1-4 shown, an embodiment of the present invention provides a large-capacity fully automatic sample handover method, which includes the following steps: (1) The operator places the sample test tube rack in the sample receiving layer within the handover module, and the carrier rack introduction mechanism transports the sample test tube rack to the refrigeration module for refrigerated storage; (2) The carrier rack transfer mechanism on the first-floor platform of the refrigeration module transports the sample test tube rack to the first-floor sample identification layer of the handover module; (3) The gripper mechanism in the sample identification layer grabs the sample test tube in the sample test tube rack, moves it to the identification area, and the identification mechanism identifies the sample; (4) According to the identification result, the gripper mechanism places the sample test tube on the classified test tube rack on the platform, and the classified test tube rack is then transported to the refrigeration module for classified storage through the carrier rack transfer mechanism.

[0036] This large-capacity fully automatic sample handover method overcomes the problem in the prior art that the processing time for handing over large-capacity samples is relatively long, which brings inconvenience to the handover personnel in blood banks. It realizes the rapid and automatic handover of large-capacity samples to a refrigerator for storage, and then the samples stored in the refrigerator are automatically scanned, identified, classified, and refrigerated by corresponding mechanisms such as a transfer mechanism, a gripper mechanism, and an identification mechanism, enhancing the convenience of large-capacity sample handover and automatically completing the entire process of identification, classification, and refrigeration of the samples after handover. This large-capacity fully automatic sample handover method reduces the workload of the staff, improves the intelligent level of sample handover processing, and improves the handover work efficiency.

[0037] As Figure 5 shown, for a large-capacity fully automatic sample handover method according to another embodiment of the present invention, steps (1) and (4) further include the following steps: The sample test tube rack in the refrigeration module can reach any layer platform of the refrigeration module through a lifting platform, and the carrier transfer mechanism on each layer platform pushes the sample test tube rack to an appropriate position for storage. The refrigeration module can be set to two layers, three layers, four layers, etc., preferably three layers. The layers of the refrigeration module are connected by a lifting platform, that is, after the sample test tube rack is received and transmitted to the refrigeration module, it can reach any layer platform of the refrigeration module through the lifting platform, and then the carrier transfer mechanism on each layer platform pushes the sample test tube rack to an appropriate position for storage. It can be understood that the refrigeration module is provided with a multi-layer structure, which can make full use of space so that all large-capacity samples can enter the refrigeration module for storage.

[0038] As Figure 5 shown, for a large-capacity fully automatic sample handover method according to another embodiment of the present invention, step (2) further includes the following steps: The sample test tube racks on the negative first floor and negative second floor platforms of the refrigeration module reach the first floor platform through the lifting platform. It can be understood that when it is necessary to identify the sample test tubes, the carrier transfer mechanism on the first floor platform of the refrigeration module transports the sample test tube rack to the first floor sample identification layer of the handover module. For the sample test tube racks stored on the negative first floor and negative second floor platforms of the refrigeration module, they reach the first floor platform through the lifting platform, and then the carrier transfer mechanism on the first floor platform transports the sample test tube rack to the first floor sample identification layer of the handover module. That is, through the lifting platform, the sample test tube racks in the refrigeration module can enter each layer of the refrigeration module for storage, or reach the first floor platform from each layer, and the carrier transfer mechanism on the first floor platform transports the sample test tube rack to the first floor sample identification layer of the handover module for sample identification, realizing the hierarchical storage and automatic identification of large-capacity samples.

[0039] As Figure 5As shown in the figure, a large-capacity full-automatic sample handover method according to another embodiment of the present invention, the step (3) further includes the following steps: a scanning head scans the bar code on the sample test tube, a camera takes a photo sample of the sample, and analyzes the characteristics of the sample and the blood quality. The gripper mechanism respectively grabs the sample test tubes in the sample test tube rack, moves them to the identification area, the scanning head scans the bar code on the sample test tube, reads the sample information, and at the same time the camera takes a photo sample of the sample, and analyzes the characteristics of the sample and the blood quality, and identifies whether the sample overflows, whether the sample volume is too small, etc., and automatically completes the rapid and accurate identification of each sample.

[0040] As Figure 5 As shown in the figure, a large-capacity full-automatic sample handover method according to another embodiment of the present invention, the step (4) further includes an empty rack recycling step, and the empty sample test tube rack is recycled through the empty rack recycling channel. An empty rack recycling channel penetrating to the bottom layer is provided in the first-layer identification area of the handover module, so that the empty sample test tube rack after the gripper mechanism grabs the sample test tubes for identification and classification can be recycled through this empty rack recycling channel. After the identification and classification process is completed, the operator can recycle the test tube rack from the exit of the empty rack recycling channel, which brings convenience to the user and can save the working space of the operation platform.

[0041] The applicant declares that those skilled in the art in the technical field, on the basis of the above embodiments, combine a certain step of the above embodiments with the technical solutions in the invention content, and the resulting new method is also within the scope of the present invention. For the sake of simplicity of the specification, other implementation manners of these steps are not listed in this application.

[0042] As Figures 1-3 As shown in the figure, a large-capacity full-automatic sample handover system includes a handover module and a refrigeration module. The handover module has a three-layer structure, namely a first-layer sample identification layer 120, a negative first-layer sample receiving layer 130, and a negative second-layer control layer 140. The refrigeration module is connected to one side of the handover module, and the refrigeration module also has a three-layer structure parallel to the three-layer structure of the handover module. A lifting platform 152 is provided between the three-layer structures of the refrigeration module, and automatic doors 151 are provided at the connections between the first layer 160 and the negative first layer 170 of the refrigeration module and the handover module.

[0043] The large-capacity fully automatic sample transfer system overcomes the problem in the prior art that the processing time for large-capacity sample transfer is relatively long, which brings inconvenience to the transfer personnel in blood banks. It realizes the rapid and automatic transfer of large-capacity samples to the refrigerator for storage, and then the samples stored in the refrigerator are automatically scanned, identified, classified, and refrigerated through corresponding mechanisms such as a transfer mechanism, a gripper mechanism, and an identification mechanism, enhancing the convenience of large-capacity sample transfer and automatically completing the whole process of identification, classification, and refrigeration of the samples after transfer. The large-capacity fully automatic sample transfer system reduces the work burden of the staff, improves the intelligent level of sample transfer processing, and improves the transfer work efficiency.

[0044] As Figures 1-3 shown, the large-capacity fully automatic sample transfer system, the first-layer sample identification layer 120 includes a gripper mechanism 121, an identification mechanism, and a carrier conveyor mechanism 124. The negative first-layer sample receiving layer 130 includes a sample receiving mechanism 131 and a carrier introduction mechanism 132. The negative second-layer control layer 140 includes a control device 141. The operator places the sample test tube rack into the sample receiving mechanism 131. The negative first-layer automatic door 151 opens, and the carrier introduction mechanism 132 introduces the sample test tube rack into the refrigeration module on the same layer for storage. After the sample test tube rack enters the refrigeration module, it can enter other layers of the refrigeration module through the lifting platform of the refrigeration module, and the automatic door 151 closes automatically. When it is necessary to identify the sample, the first-layer automatic door 151 opens, and the sample test tube rack is conveyed to the first-layer sample identification layer of the transfer module. The gripper mechanism 121 grabs the sample test tube and moves it to the identification area, and the identification mechanism identifies the information and quality of the sample. The identified sample test tube is placed on the classification test tube rack and conveyed to the refrigeration module for classified storage through the carrier conveyor mechanism. The control device 141 is electrically connected to each mechanism, stores and analyzes data information, and issues command signals to control the automatic operation of each mechanism.

[0045] As Figure 1 shown, the gripper mechanism 121 is arranged above the first-layer sample identification layer 120 of the transfer module. The gripper mechanism 121 has five degrees of freedom in X, Y, Z, R, and G, and can move, grab, and transfer test tubes. The gripper mechanism is electrically connected to the control device. The gripper mechanism 121 automatically grabs the sample test tubes conveyed to the identification layer, moves them to the identification area, and the gripper mechanism 121 drives the sample test tubes to rotate, and the identification mechanism identifies the information and quality of the samples.

[0046] As Figure 1As shown in the figure, the gripper mechanism 121 includes a scanning head 123 and a camera 122. The scanning head 123 can scan the barcodes on the sample tubes, and the camera 122 can take pictures and sample the sample tubes. The scanning head 123 and the camera 122 are electrically connected to the control device 141 respectively. The scanning head 123 reads the sample information, and at the same time the camera 122 takes pictures and samples the sample, analyzes the characteristics of the sample and the blood quality, such as whether the sample overflows, whether the sample volume is too small, etc., and automatically completes the rapid and accurate identification of each sample. The identification information is transmitted to the control device 141, and the control device 141 stores, analyzes and processes the data.

[0047] As Figure 1 shown in the figure, a classification test tube rack 128 is provided on the operation platform of the first-layer sample identification layer 120. Generally, it can be divided into biochemical, enzyme immunoassay and nucleic acid categories according to the experimental items. According to the identification information, the gripper mechanism 121 places the sample tubes into their respective classification test tube racks. An abnormal temporary storage area is also provided on the operation platform for storing the identified abnormal specimens, which will be taken out later for manual processing. When the classification test tube rack is full of sample tubes, the classification test tube rack is conveyed to the refrigeration module for storage by the rack conveying mechanism. Of course, each layer of the refrigeration module can also be separately set as a biochemical layer, an enzyme immunoassay layer and a nucleic acid layer, and the classification test tube rack reaches the corresponding layer area through a lifting platform for refrigerated storage. After the handover and classification processing are completed, the operator can directly take out the samples from the corresponding layer area of the refrigeration module and directly perform the subsequent corresponding detection experiments, which greatly brings convenience to the users.

[0048] As Figures 1-3 shown in the figure, the handover module is also provided with an empty rack recycling channel for recycling the empty sample tube racks after sample identification. An empty rack recycling channel 125 that penetrates to the bottom layer is provided in the first-layer identification area of the handover module, so that the empty sample tube racks after the gripper mechanism 121 grabs the sample tubes for identification and classification can be recycled through the empty rack recycling channel 125. After the identification and classification processing is completed, the operator can recycle the test tube rack from the exit of the empty rack recycling channel, which brings convenience to the users and can save the working space of the operation platform.

[0049] The applicant also declares that the present invention uses the above embodiments to illustrate the implementation method and system structure of the present invention, but the present invention is not limited to the above embodiments. Any improvements, equivalent replacements, increases or decreases of steps, and selections of specific methods by those skilled in the technical field all fall within the protection scope of the present invention.

[0050] The working process of this large-capacity fully automatic sample handover system is as follows:

[0051] S110: The operator places the sample test tube rack in the sample receiving layer within the handover module, and the rack import mechanism transports the sample test tube rack to the refrigeration module for refrigerated storage;

[0060] Compared with the prior art, the large-capacity full-automatic sample handover method of the present invention can achieve rapid handover of a large number of samples outside the department and transport them to the refrigeration module for storage. Then, the samples stored in the refrigeration module are automatically transported to the sample identification layer of the handover module, and the identification mechanism automatically scans and identifies the samples. The gripper mechanism classifies the samples according to the identification result, and the classified samples are then automatically transported to each layer of the refrigeration module for classified storage.
