Currently, conventional blood collection management systems are still widely used in most hospitals. In blood sampling management system, take the heparin tube that patient's blood sample used, can relate to the selection of heparin tube type, paste bar code label in the use, processes such as blood sampling process, blood sampling sample are typeeed, handing-over, are transported, are collected and letter sorting. At present, no matter the selection of heparin tube type or paste the bar code label that has patient information at this heparin tube, all rely on manual operation to accomplish or have corresponding independent equipment to accomplish, but can not realize the automatic linking of action, follow-up transport, the letter sorting of heparin tube after having gathered blood also mostly are the operation, whole in-process not only work load is big, cause the error easily moreover, can consume a large amount of manpowers and time, and paste the mark uniformity not good. Labeling inconsistency often causes that the following inspection equipment cannot be well identified, and the overall working progress is influenced. In addition, the traditional blood sampling management system is lack of unified management on personal information and blood sampling item information of patients, and the problem of inconvenience in input and query often exists.
At present, most of domestic large and medium medical institutions establish a LIS (Laboratory information System) which includes a function of managing clinical specimens. However, the LIS system adopts manual bar code scanning to perform information entry and reception confirmation of clinical test specimens. Because the entry efficiency of manual bar code scanning is low (1.5 s/sample on average), a large number of samples can greatly consume the energy of medical staff, and the probability of errors caused by manual entry can also rise along with the increase of the number of samples. Meanwhile, because the manual scanning efficiency is low and contradicts with the limitation of the sample conveying time required in the actual medical work, the deficiency of part of the information checking process in the existing sample collecting, transferring and receiving links is caused, so that the real-time information of the samples during the collecting, transferring and receiving processes to the clinical laboratory is dead zones, the samples are missed and mistakenly found in the time period, the great medical hidden danger is caused, and the medical responsibility is difficult to be divided.

the first control unit is used for verifying whether the RFID labels of the sample containers are accurate or not according to the written and read ID information, and is also used for controlling the driving mechanism to adjust the transmission direction of the conveyor belt and loading the sample containers with the same ID information into the same tray.
In the embodiment, the output channel is communicated with the labeling and printing mechanism, and the output channel is provided with a second reading and writing unit for reading the ID information of the sample container with the RFID label;
the second reading and writing units comprise antennas and readers, whether the ID information in the RFID tags of the sample containers is the same as the ID information written in the sample containers is checked by reading the ID information in the RFID tags of the sample containers, the purpose of checking is achieved on one hand, and on the other hand, the subsequent first control unit can conveniently load the sample containers with different ID information into different trays according to the ID information.
A conveyor belt having a drive mechanism, the conveyor belt having a plurality of trays for holding specimen containers disposed in sequence thereon;
wherein each tray loads a specimen container of the same patient according to the RFID label attached to the specimen container; when the number of the specimen containers of one tray cannot be loaded with the same patient, the next tray is called to continue loading. Because the number of the specimen containers contained in each tray is fixed, when one tray can not be filled with specimen containers with the same ID information, the next tray is only required to be called to continue loading, and each tray is ensured to be only filled with specimen containers of one patient.
On the basis of the above embodiment, the method further comprises the following steps:
and a position sensor is arranged below the output channel and on the side surface of the conveyor belt and used for detecting a position signal of the tray, and the first control unit controls the conveyor belt to drive forwards according to the position signal of the tray so that the tray to be loaded with the specimen container is aligned to the output channel.

In the embodiment, the first control unit controls the rotation of the transmission belt by controlling the phase change of the driving mechanism, and the transmission belt always transmits in the same direction. For example, each tray can only load a preset number of sample containers, and when the number of the sample containers with the same ID is verified to be more than the preset number, the conveyor belt is controlled to move to call the next tray to continuously load the sample containers; conversely, when the second reading unit reads that the ID information is different from the ID information corrected previously, the next tray is called to load the sample container, ensuring that each tray only loads the sample container of the same ID information. First the control unit is the terminal of taking the display screen for label packing's state is pasted to the label according to the RFID label display specimen container, thereby be convenient for patient and operating personnel to know.
Specifically, each tray is preset at the position of the conveyor belt, the middle of the tray is aligned under the output port of the output channel, namely the length of the tray is longer than that of the output channel, a first position sensor and a second position sensor are arranged on one side of the conveyor belt along the conveying direction of the conveyor belt according to the length of the tray, the installation distance of the first position sensor and the second position sensor on the conveyor belt is longer than the length of one tray and is located between the gaps of two adjacent trays, when the first position sensor detects the tray signal, a first trigger signal is sent, when the second position sensor does not detect the tray signal and the first position sensor also does not detect the tray signal, namely when the position sensor passes through the gap detection, the tray is determined to be aligned with the output port of the output channel. When the control conveyor belt rotates to move to the next tray aligning output channel, the second position sensor detects the position signal from the absence to the presence and then returns to the absence, and the control conveyor belt is aligned with the output port of the output channel.
One side of the tray is movably connected to the conveyor belt, so that the tray can be turned over laterally along the conveying direction; a pushing mechanism for pushing the side face of the tray to turn is arranged on one side of the conveying belt, and a packing mechanism for loading a specimen container is correspondingly arranged on the other side of the conveying belt.
