Description

TECHNICAL FIELD

[0002] Generally, gauze is used for hemostasis in surgical operation. However, due to the deep body cavity of some surgical sites, in order to avoid the gauze left in the patient's body, the gauze must be accurately counted before and after the operation. At present, most of the counting process is mainly counted by artificial statistics, or the gauze with X-ray developing line is used to prevent medical disputes caused by gauze left in the patient's body, wherein the X-ray developing line contains developing agent. When the number of gauze used does not match the counted number, an X-ray machine is used to scan the patient, and the anti-radiation performance of the X-ray developing line is used to judge whether the gauze is still in the patient's body through fluoroscopy or radiography.

[0003] However, manual counting is prone to errors, and the structure of the X-ray developing line is fragile and prone to damage or breakage, so it cannot be ensured that the gauze is not left in the patient's body. In addition, the X-ray detector has radioactive substances, and its detection is easy to harm the health of the patient. In recent years, with the progress of wireless radio frequency identification technology, there are products in the market that combine wireless radio frequency identification labels with gauze, but most of them are fixed on the gauze by sewing or directly pasting. This production method not only takes time, but also has a gap between the wireless radio frequency identification label and the gauze, which is easy to have liquid seepage, affecting the use efficiency of the wireless radio frequency identification label. Therefore, there is still a need for a wireless radio frequency identification label that is easier to make and can more closely integrate the gauze. SUMMARY

The low to medium temperature hot melt adhesive is used to combine the heat transfer wireless radio frequency identification tag with the fabric material. The temperature of the process is only required to be between 100 to 140 degrees Celsius, which can complete the fixation of the heat transfer wireless radio frequency identification tag with the fabric material. In addition to the convenience of combination, the fibers of the fabric material such as gauze or surgical towel will not be damaged and the shrinkage will not be affected due to high temperature. Therefore, when the fabric material with the heat transfer wireless radio frequency identification tag is applied to the human body, the heat transfer wireless radio frequency identification tag has skin-friendliness and flexibility, so there is no obvious foreign body sensation. In addition, when the wireless radio frequency identification tag is combined with the fabric material by hot pressing, the hot melt adhesive will penetrate into the fibers of the fabric material to have a more tight bonding strength. When the fabric material is immersed in liquid (for example: blood), the wireless radio frequency identification tag will not be affected by the liquid penetration to reduce the performance, and has a longer service life.
