Description

Technical Field

[0001] The utility model relates to the technical field of RFID tags, and in particular to an RFID tag for inventory management of medical consumables. Background Art

[0002] In RFID (radio frequency identification technology), since each RFID tag is unique, a one-to-one correspondence can be established between the RFID tag and the product. RFID is often used in the field of anti-counterfeiting, such as the anti-counterfeiting of valuable items such as wine and medicine.

[0003] For example, patent application number CN202020716680.8 provides an RFID tag suitable for inventory management of medical consumables, including a fragile base film, an RFID antenna and a coating, the RFID antenna including a near-field coil and a far-field coil, the far-field coil and the near-field coil constitute an ultra-high frequency RFID antenna, wherein the far-field coil and the near-field coil are stacked together by an insulating film, the fragile base film, the RFID antenna and the coating constitute a fragile RFID tag, which has the functions of anti-uncovering and anti-transfer, and when uncovered, the far-field coil and the near-field coil are broken at the same time, which is convenient for inventory registration of disposable medical consumables; the unique barcode information can be saved in the RFID tag and entered into the inventory system of medical consumables, which is convenient for inventory registration and tracking of each medical consumable, and the RFID tag can be pasted on the opening of the medical consumables packaging.

[0004] Based on the above search and in combination with the prior art, it is found that although the RFID tags for medical consumables inventory management similar to the above disclosed in the prior art can play a good anti-counterfeiting role, once uncovered, the barcode information is lost, resulting in the inability to conduct a second view, which has certain disadvantages in use. Therefore, an RFID tag for medical consumables inventory management is proposed to improve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example: Reference Figure 1-5 An RFID tag for inventory management of medical consumables shown includes a label paper 1, an RFID antenna, a coating layer 4 and an adhesive layer 7, wherein the coating layer 4 is arranged on one end surface of the label paper 1, and the adhesive layer 7 is arranged on the other end surface of the label paper 1.

[0027] Among them, the RFID antenna includes a first RFID antenna 2 and a second RFID antenna 3, the first RFID antenna 2 and the second RFID antenna 3 are respectively arranged on both sides of the label paper 1, and a connecting layer 5 is arranged on the side of the first RFID antenna 2 and the second RFID antenna 3 away from the coating layer 4, the connecting layer 5 includes a connecting portion 51 and a breakable portion 52, the connecting portion 51 and the breakable portion 52 are distributed at intervals in the area where the orthographic projection of the second RFID antenna 3 is located, and the connecting portion 51 is completely distributed in the area where the orthographic projection of the first RFID antenna 2 is located.

[0028] It should be further explained that the bonding force of the adhesive layer 7 where the fragile portion 52 is located is greater than the sum of the breaking strengths of the fragile portion 52, the second RFID antenna 3 and the coating layer 4. When the label is removed again after being affixed, the second RFID antenna 3 is disconnected from the position of the fragile portion 52, preventing the user from affixing the label to other products for counterfeiting.

[0029] By setting a first RFID antenna 2 that is not easily destroyed and a second RFID antenna 3 that is easily destroyed on the same label paper 1, the information contained in the first RFID antenna 2 and the second RFID antenna 3 is the same. While the destroyed second RFID antenna 3 is used to effectively prevent counterfeiting, the user can also obtain the barcode information of the product through the first RFID antenna 2 that is not easily destroyed, which has better applicability.

[0030] Specifically, the first RFID antenna 2 includes a first far-field coil 21 and a first near-field coil 22. An insulating film layer 6 is arranged between the first far-field coil 21 and the first near-field coil 22. The first far-field coil 21 is located on the side of the insulating film layer 6 close to the adhesive layer 7, and the first near-field coil 22 is located on the side of the insulating film layer 6 close to the coating layer 4.

[0031] Similarly, the second RFID antenna 3 includes a second far-field coil 31 and a second near-field coil 32. An insulating film layer 6 is also arranged between the second far-field coil 31 and the second near-field coil 32. The second far-field coil 31 is located on the side of the insulating film layer 6 close to the adhesive layer 7, and the second near-field coil 32 is located on the side of the insulating film layer 6 close to the coating layer 4.

[0032] Among them, the label paper 1 is respectively provided with a groove 101 and a through hole 102 adapted to the first RFID antenna 2 and the second RFID antenna 3. The groove 101 is located on the side of the label paper 1 close to the coating layer 4, and a connecting groove 103 is provided in the middle of the side of the label paper 1 close to the coating layer 4. The groove 101 is connected with the through hole 102 through the connecting groove 103. Part of the first near-field coil 22 extends to the inner side of the through hole 102 through the connecting groove 103 to prevent the user from maliciously cutting the label paper 1 to separate the first RFID antenna 2 for separate use.

[0033] The orthographic projection of the first near-field coil 22 partially overlaps with the first far-field coil 21 , and the orthographic projection of the second near-field coil 32 partially overlaps with the second far-field coil 31 .

[0034] The first far-field coil 21 is electrically connected to the first near-field coil 22 in cascade connection, and the second far-field coil 31 is electrically connected to the second near-field coil 32 in cascade connection.

[0035] Working principle of the utility model: when the label is peeled off again after being affixed, since the bonding force of the adhesive layer 7 where the fragile portion 52 is located is greater than the sum of the breaking strengths of the fragile portion 52, the second RFID antenna 3 and the coating layer 4, the second RFID antenna 3 is disconnected from the fragile portion 52 to prevent the user from affixing the label to other products for counterfeiting. By arranging the first RFID antenna 2 that is not easily damaged and the second RFID antenna 3 that is easily damaged on the same label paper 1, the first RFID antenna 2 and the second RFID antenna 3 contain the same information. While the damaged second RFID antenna 3 is used to effectively prevent counterfeiting, the user can also obtain the barcode information of the product through the first RFID antenna 2 that is not easily damaged, and the applicability is better.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
