[0021] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] It should be noted that in this text, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising that element.

[0023] In this text, suffixes such as "module", "component" or "unit" used to denote elements are only for the convenience of describing the present utility model and have no specific meaning in themselves. Therefore, "module" and "component" can be used interchangeably.

[0024] As Figure 1 shown, an embodiment of the present utility model provides a pipeline consumable identification device 10 based on a blood purification device, which includes a reading and writing device 11 and an electronic tag 12. Among them, the reading and writing device 11 is built into the blood purification device, and the electronic tag 12 can be pasted on the pipeline consumable.

[0025] The electronic tag 12 in the embodiment of the present utility model is a radio frequency identification tag. The reading and writing device 11 is used to implement the functions of a reader and data management. When the reading and writing device 11 emits radio waves to the electronic tag 12, the electronic tag 12 will absorb the radio wave energy and convert it into electrical energy to activate the microprocessor in the electronic tag 12. At this time, the electronic tag 12 reads and rewrites digital information according to the instructions sent by the reading and writing device 11.

[0026] In the actual application based on the blood purification device, when medical staff use the pipeline consumable, the distance between the reading and writing device 11 and the pipeline consumable meets the reading and writing distance. Furthermore, the distance between the reading and writing device 11 and the electronic tag 12 meets the reading and writing distance. Therefore, the reading and writing device 11 can perform anti-counterfeiting identification on the digital information in the electronic tag 12 before the pipeline consumable contacts the human body, and rewrite the digital information of the electronic tag 12 after the treatment, ensuring the quality of the pipeline consumable during the treatment process and preventing the reuse of disposable consumables. Compared with separately identifying the authenticity of the pipeline consumable, the above process does not increase the workload of medical staff, does not affect the use of the blood purification device by medical staff, ensures work efficiency, and the reading and writing device is completely built into the device, does not occupy the volume of the device, and does not affect the appearance.

[0027] In one embodiment, the electronic tag includes an adhesive layer and an RFID tag body fixed on the adhesive layer. Exemplarily, the electronic tag can be an M1 series adhesive paper electronic tag. In terms of product performance, this electronic tag complies with the ISO14443A standard, has an operating frequency of 13.56 MHz, and a storage capacity of 1 KB. In terms of product appearance, this electronic tag adopts a flexible design, and the tag size can be customized according to needs and can be pasted on the surfaces of various objects.

[0029] Among them, the radio frequency module 114 provides a low-power radio wave emission function. As Figure 3 shown, in the embodiment of the present utility model, the radio frequency module 114 includes a first emission circuit TX1, a second emission circuit TX2, and a reception circuit RX. Based on this circuit structure, the operating modes of the radio frequency module 114 include the first emission circuit TX1 working alone, the second emission circuit TX2 working alone, or the first emission circuit TX1 and the second emission circuit TX2 working in a cooperative and complementary manner. When the first emission circuit TX1 works alone, the second emission circuit TX2 is turned off. When the second emission circuit TX2 works alone, the first emission circuit TX1 is turned off, realizing a single-channel working mode. In the reception circuit RX, by adjusting the voltage-dividing resistance values of R24 and R33, the received signal is brought within a suitable range. In the first emission circuit TX1 and the second emission circuit TX2, the capacitors C44, C45, C46, and C47 are used to match the antenna to make the frequency reach 13.56 MHz.

[0030] In a preferred embodiment, the radio frequency module 114 uses an FM17550 non-contact communication chip as the main chip. The FM17550 non-contact communication chip operates at 13.58 MHz, supports the ISO 14443 TypeA / TypeB protocols, and simultaneously provides a low-power fast emission field function. It supports multiple communication rates, and the reading and writing distance can reach 50 mm, which is an easily satisfied reading and writing distance during the use of the blood purification device. At the same time, it has the characteristics of low voltage, low power consumption, strong driving ability, and multi-protocol support.

[0031] In a preferred embodiment, the power supply module 111 uses a low-dropout linear voltage regulator to convert the 5V power supply provided by the blood purification device into a 3.3V power supply for other modules.

[0032] In a preferred embodiment, the communication bus 112 communicates with the main control module through the interface mode of SPI (Serial Peripheral Interface).

[0033] In a preferred embodiment, the main control module 113 uses a microcontroller unit, which is an integrated circuit chip integrating a processor core, a memory, input / output interfaces, and other peripherals. It has the characteristics of high integration, small size, and rich peripherals, and is mostly used in embedded systems.

[0034] In a preferred embodiment, the antenna 115 is a PCB (Printed Circuit Board) on-board antenna. As the transmitting end of radio waves, it sends signals to the electronic tag 12 and also receives the digital information in the electronic tag 12. The on-board antenna is a highly integrated antenna, which has the advantages of high stability, strong reliability, low cost, beauty, and easy maintenance, and is widely used in electronic products.
