The wristband records the deceased's information to facilitate identification by staff and subsequent work. In actual use, the wristband may break due to external factors, and the staff may not be aware of the breakage, causing subsequent work to be unable to proceed normally. In order to solve the above problems, this solution was developed. Utility Model Content
[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an RFID tag and wristband that can detect the integrity of the wristband and can detect the wristband breakage in time.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an RFID tag that can detect the integrity of a wristband, including an RFID chip and a monitoring circuit, wherein the monitoring circuit spans the wrapping area of the wristband, and the RFID chip is used to detect whether the monitoring circuit is open-circuited.
[0005] Furthermore, the monitoring circuit is a metal wire.
[0006] Furthermore, one end of the metal wire is connected to the RFID chip, bypasses the wrapping area across the wristband, and then connects to the other end of the metal wire, which is then connected to the RFID chip.
[0007] Furthermore, there are two RFID chips, which are located on both sides of the wrapping area across the wristband, and the two ends of the metal wire are connected to the two RFID chips respectively.
[0008] Furthermore, the RFID tag also includes an RFID antenna body, which is electrically connected to the RFID chip and is used to transmit signals and power the RFID chip.
[0009] Furthermore, the RFID tag also includes two RFID antenna bodies, which are electrically connected to two RFID chips respectively. The RFID antenna bodies are used to transmit signals and power the RFID chips.
[0010] A wristband includes a wristband body and an RFID tag, the RFID tag being located within the wristband body, the wristband body having a wrapping area, and a monitoring loop spanning the wrapping area of the wristband.
[0011] A wristband includes a wristband body and an RFID tag, the RFID tag being located within the wristband body. The wristband body has a wrapping area, an integration area connected to one side of the wrapping area, and an RFID antenna body located within the integration area.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention features an RFID tag on the wristband body. The monitoring circuit in the RFID tag spans the wrapping area of the wristband body. When the wristband body is worn on the wrist, the wrapping area will surround the wrist. If the wrapping area is damaged, the wristband body will fall off the wrist. At this time, the monitoring circuit in the wrapping area will also be broken, causing the RFID chip to lose signal. This will send an electrical signal to the host computer to issue a warning, reminding the staff that the wristband body is damaged and needs to be inspected and replaced immediately.

[0019] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.
[0020] Example 1
[0021] like Figure 1 As shown, this embodiment provides a wristband, including a wristband body 1 and an RFID tag 2 that can detect the integrity of the wristband.
[0022] The RFID tag 2 is located inside the wristband body 1. The wristband body 1 has a wrapping area 11. One side of the wrapping area 11 is connected to the integrated area 13, and user information is marked on the surface of the integrated area 13. The other side is connected to the buckle area 12. One side of the buckle area 12 extends outward to form an extension. The extension length is greater than or equal to the width of the wrapping area 11. The wrapping area 11 is provided with multiple spaced through holes 111. The buckle area 12 is provided with left and right spaced locking holes 121, one of which is located on the extension. The wrapping area 11 wraps around the user's wrist, with the integrated area 13 on the outside and the buckle area 12 on the inside of the wrapping area 11, and one locking hole 121 corresponding to any one of the through holes 111. The extension bends to the other surface of the wrapping area 11. Two buckles and any one of the through holes 111 correspond to each other and are connected by an anti-tamper buckle. The anti-tamper buckle adopts a structure commonly used in the prior art, which will not be described in detail here.
[0023] The RFID tag 2 includes an RFID chip 21, a monitoring loop 22, and an RFID antenna body 23. The RFID antenna body 23 and the RFID chip 21 are located within the integration area 13 and are electrically connected. The RFID antenna body 23 is used to transmit signals and power the RFID chip 21. Specifically, the RFID antenna body 23 transmits the signals collected by the RFID chip 21 to the host computer. The monitoring loop 22 spans the wrapping area 11 of the wristband. Specifically, the monitoring loop 22 is a metal wire. One end of the metal wire is connected to the RFID chip 21, bypasses the wrapping area 11 of the wristband, and then folds back to connect the other end of the metal wire to the RFID chip 21.
[0024] When the wristband breaks, the metal guide wire also breaks. The RFID chip 21 detects the abnormality of the monitoring circuit 22 and sends a signal to the host computer via the RFID antenna body 23. The staff can determine whether the wristband is broken by checking the abnormality display on the host computer and remind the staff on site to check and replace it in time.
[0025] Example 2
[0026] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that there are two RFID chips 21. The two RFID chips 21 are located on both sides of the wrapping area 11 across the wristband, and the two ends of the metal wire are connected to the two RFID chips 21 respectively. The RFID antenna body 23 is used to power the two RFID chips 21. Specifically, one RFID chip 21 is located in the wrapping area 11 near the buckle area 12, and the other RFID chip 21 is located in the integration area 13. A monitoring circuit 22 is provided between the two RFID chips 21, and the monitoring circuit 22 is a metal guide wire.
[0027] When the wristband breaks, the metal guide wire also breaks. The two RFID chips 21 detect the abnormality of the monitoring circuit 22 and the RFID antenna body 23 sends a signal to the host computer staff. The host computer staff can determine whether the wristband is broken by displaying the abnormality and remind the staff on site to check and replace it in time.
[0028] Example 3
[0029] like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the wristband body 1 has a wrapping area 11, and an integrated area 13 is connected to both sides of the wrapping area 11. The wristband body 1 is connected by the overlapping through holes 111 on both sides of the wrapping area 11 through anti-tamper buckles.
[0030] There are two RFID chips 21 and two RFID antenna bodies 23. Each integrated area 13 has one RFID chip 21 and one RFID antenna body 23. A monitoring circuit 22 is set between the two RFID chips 21. The monitoring circuit 22 is a metal guide wire, and there is one metal guide wire.
[0031] When the wristband breaks, the metal guide wire also breaks. The two RFID chips 21 detect the abnormality of the monitoring circuit 22, and the two RFID antenna bodies 23 send signals to the host computer staff. Through the abnormality display on the host computer, the staff can determine whether the wristband is broken and remind the staff on site to check and replace it in time.
[0032] Preferably, there are two metal guide wires, which are located on both sides of the through hole 111. When a part of the wristband breaks, causing one of the metal guide wires to break, the two RFID antenna bodies 23 send a signal to the host computer staff. The host computer displays the abnormality and notifies the staff that the wristband has partially broken and needs to be detected and dealt with in time.
[0033] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
