Description

Technical Field

[0001] The utility model relates to the technical field of RFID tags, in particular to a blood bag integrated with an RFID tag. Background Art

[0002] As early as 2019, the National Medical Products Administration issued requirements for the use of a unique identification system for medical devices. According to Article 11 of the [Appendix to the National Medical Products Administration's Official No. 66 of 2019], it is clearly stated: "The unique identification data carrier of medical devices shall meet the requirements of automatic identification and data collection technology and manual reading. If space is limited or use is restricted, the carrier form that conforms to automatic identification and data collection technology shall be used first. Automatic identification and data collection technologies include one-dimensional codes, two-dimensional codes or radio frequency tags, and the use of advanced automatic identification and data collection technologies is encouraged."

[0003] Medical blood bags are one of the key production and key supervision categories of medical devices, and are important medical device products related to the safety of medical blood. At present, although the medical blood bags on the market are strictly assigned the unique identification code (UDI) required for medical devices in accordance with the requirements of the Food and Drug Administration, the UDI system, namely the unique identification system for medical devices, is an identification system established to quickly and accurately identify all aspects of medical device production, operation and use, realize full life cycle management, and improve regulatory efficiency. However, most of them are in the form of printing or printing the UDI code on the label paper, and then attaching the label paper to the blood bag. The disadvantages of this method are: a. The label paper with the UDI code is attached to the blood bag by gluing, and the label paper is easily contaminated and damaged; b. Criminals can make UDI code labels by identifying the UDI code on the label paper and attach them to inferior blood belts for use; c. Recently, the market has seen the embedding of RFID into the finished blood bag label. The purpose of this method is only to facilitate the inventory and storage management of blood bags, and it cannot truly realize the uniqueness of the blood bag identity.

[0004] At the same time, in the prior art, the Chinese patent authorization number is: CN216310819U, and the name is a blood bag patent. Its implementation method is not truly embedded, but it adopts a method of adding an RFID tag placement cavity on the upper surface of the existing blood bag. The cost is high, the RFID tag is still easy to be transferred, and this area is in direct contact with the liquid, which directly affects the radio frequency performance of the RFID tag. Utility Model Content

[0005] In view of the above problems, the utility model provides a blood bag which is simple in structure and has improved safety and is integrated with an RFID tag.

[0006] The technical solution of the utility model is: a blood bag integrated with an RFID tag, comprising a blood bag body, an RFID tag with a UDI code, and a self-adhesive label with a UDI code.

[0007] The blood bag body comprises an upper plastic layer and a lower plastic layer arranged one above the other, wherein a blood bag liquid cavity area and a blood bag non-liquid cavity area are formed between the upper plastic layer and the lower plastic layer;

[0008] The RFID tag is heat-sealed and connected to the non-liquid cavity area of ​​the blood bag body;

[0009] The self-adhesive label is connected to the surface of the blood bag liquid cavity area in the blood bag body.

[0010] The RFID tag is located between the upper plastic layer and the lower plastic layer.

[0011] The self-adhesive label is located on the surface of the upper plastic layer or the lower plastic layer.

[0012] The UDI code on the self-adhesive label is marked by printing or imprinting.

[0013] The UDI code on the self-adhesive label is a one-dimensional code and / or a two-dimensional code.

[0014] The upper plastic layer and the lower plastic layer are made of the same material, which is polyethylene or polyvinyl chloride.

[0015] The two UDI code data in the RFID tag and the self-adhesive label are the same.

[0016] During operation, the utility model directly embeds the RFID tag into the blood bag, writes the UDI code into the memory of the RFID tag chip, and encrypts the written data to prevent it from being tampered with at will. At the same time, the written UDI code is consistent with the one-dimensional code and two-dimensional code with the UDI code attached to the blood bag, which can meet the requirements of visual multi-code verification in the medical field and can truly achieve effective traceability of one object with one code.

[0026] The utility model Figure 1-4 As shown, the blood bag integrated with the RFID tag comprises a blood bag body 1, an RFID tag 2 with a UDI code and a self-adhesive label 3 with a UDI code, wherein the RFID tag is embedded in the blood bag body, and the self-adhesive label is attached to the top of the blood bag body, and the two UDI code data are consistent.

[0027] The RFID tag 2 is embedded in the non-liquid cavity area 5 of the blood bag, which can avoid the influence of the cavity liquid on the performance of the RFID tag, so that the tag has a better writing and reading effect.

[0028] The structure of the RFID tag embedded in the blood bag is a three-layer structure, including an upper plastic layer, an RFID tag, and a lower plastic layer, wherein the plastic layer is a medical-grade plastic material that meets medical standards, such as polyethylene or polyvinyl chloride, to ensure that the material is non-toxic and sterile. The RFID tag part can be a label with or without glue.

[0029] A blood bag liquid cavity area 4 (i.e., an area for contacting blood) and a blood bag non-liquid cavity area 5 (i.e., an area not in contact with blood) are formed between the upper plastic layer 11 and the lower plastic layer 12; the self-adhesive label is connected to the surface of the blood bag liquid cavity area 4 in the blood bag body.

[0030] The self-adhesive label 3 is located on the surface of the upper plastic layer or the lower plastic layer.

[0031] The RFID tag is embedded in the blood bag in such a way that during the stage of heat-sealing the bag using the upper and lower plastic layers, the RFID tag is placed in the middle layer of the area that needs to be heat-sealed.

[0032] The heat sealing method is to use a high-frequency electric field to make the internal molecules of the plastic oscillate to generate heat energy to fuse them into bags.

[0033] The RFID tag can be designed according to requirements, and the RFID tag can be placed at any position in the heat-sealing area.

[0034] In the application of the utility model, an RFID tag with data storage and data encryption functions is embedded in a blood bag, a UDI code is marked on a self-adhesive label by printing or printing, the UDI code information on the self-adhesive label is read by a code scanning instrument, the UDI is written into the memory of the RFID chip embedded in the blood bag, and the written content is locked or encrypted;

[0035] Alternatively, the UDI code may be first written into the memory of the RFID chip embedded in the blood bag, and then the UDI code written into the blood bag may be read by a radio frequency device, and the obtained UDI code may be marked on a self-adhesive label by printing or printing, and finally the self-adhesive label with the UDI code may be attached to the blood bag with the same UDI code.

[0036] The utility model embeds the RFID tag into the blood bag and writes the UDI code into the RFID tag, so as to achieve a one-to-one correspondence between the UDI code of the RFID tag and the UDI code on the visualized self-adhesive label, effectively ensuring the uniqueness of the blood bag, and at the same time solving the risks of the existing single self-adhesive label being easily contaminated, damaged, or detached from the surface UDI code; and has the advantages of batch inventory and rapid identification of RFID tags.
