Abstract

A tape-type electronic label for operating room instruments. The electronic label is used for operating room instruments. It is only necessary to appropriately trim the length of the strapping tape, tear off the release paper, and connect the label part and the strapping tape. If the resonant hole slot of the antenna is close to the operating room instrument and the loop is located at the outer edge of the operating room instrument, it can be installed in various types or specifications by wrapping the strip-shaped tape around it. On the operating room instrument, the tag part is used as a wireless identification that is not easy to lose; in this way, the electronic tag installed on the operating room instrument uses the resonance hole slot of the pair of guide loops of the antenna and the operating room instrument. The electromagnetic wave signal resonates, so that the remote reading device can stably read the ID identification code of the radio frequency identification chip against metal interference, and can obtain the identification effect of long-distance reading.

Description

Tape-type electronic labels for operating room instruments

The present invention relates to an electronic tag that can be easily and not lost easily installed on operating room instruments of various types or specifications, and has metal resistance and long-distance reading and identification performance. In particular, it relates to a tape-type electronic tag for operating room instruments.

Today's medical institutions are constantly striving to improve the quality of medical care to avoid the occurrence of medical negligence; but unfortunately, medical negligence is still inevitable. Therefore, the issue of patient safety has always been one of the most important issues for the World Health Organization (WHO) and European, American and Japanese countries. It is also an important issue for the health care service systems of various countries around the world.

The operating room is indeed a high-risk, high-cost, complex, professional, and high-tech unit. Generally, surgery must be performed by a team composed of surgeons, anesthesiologists, anesthesia nurses, mobile nurses and other operating room personnel. In the case of medical errors, 16.9% of surgical adverse events are due to medical negligence. In order to reduce medical errors and negligence and improve the safety of pre-operative care for patients in the operating room, the pre-operative disinfection supply department counts and packs instruments; supervises the use of instruments during the operation; and recovers, sorts, counts and disinfects the instruments after the operation. work is extremely important. RFID radio frequency identification technology is used for the identification of surgical instruments, which should bring safety and efficiency to the above work, especially the identification/tracking of surgical instruments before and after use. The hospital can ensure complete and thorough disinfection, avoid the risk of nosocomial infection, or avoid Medical accidents occur where surgical instruments are left in the human body.

The existing sticker-type RFID electronic tags on the market are generally attached to the equipment only by adhesive, and are easy to be lost during cleaning and disinfection. If they are attached to metal equipment, there is also the problem of metal interference with communication.

Although the patent application No. TW202226261A "Electronic Identification Device for Operating Room Instruments" previously published by this invention can improve the above-mentioned disadvantages of sticker-type electronic tags being easy to lose and susceptible to metal interference, the only problem is that the telescopic strap of the base is buckled and fixed around the instrument. The caliber (size) cannot be adjusted, so the applicable objects are subject to many restrictions. Especially when the base is molded (made), the male and female fasteners must be embedded in the molding mold in advance. This is a careful and time-consuming process. This greatly affects the production efficiency of the identification device.

A covering film, which is a flexible insulating film sheet relative to the shape of the base material sheet, is attached to the surface of the base material sheet, covers the antenna and the radio frequency identification chip to form a protective surface layer, and is connected with the The disc-shaped film and the strip-shaped film together constitute a label part and a bundle Strip tape; an adhesive layer, which is attached to the entire lower surface of the long strip of film on the bottom surface of the base material sheet, and is coated with adhesive to form a self-adhesive layer; a release paper, which is attached to the adhesive layer The adhesive coating shape of the adhesive layer is adhered to the surface of the adhesive layer; if you want to use the electronic label for operating room instruments, you only need to appropriately trim the length of the binding strip tape and tear off the release paper , with the resonant hole slot of the antenna at the connecting position of the label part and the strip-shaped tape close to the operating room instrument, and the loop loop is located at the outer edge of the operating room instrument, that is, The strip-shaped tape is looped and attached to operating room instruments of various types or specifications, and the tag portion is used as a wireless identification for those that are not easily lost; in this way, the electronic tag installed on the operating room instrument utilizes the pair of antennas The resonance slot of the guidance loop resonates with the electromagnetic wave signal on the operating room instrument, so that the remote reading device can stably read the ID identification code of the radio frequency identification chip against metal interference, and can obtain long-distance reading. Get the recognition effect.

A second object of the present invention is to provide a tape-type electronic label for operating room equipment, wherein the base material sheet is a copper foil flexible board (Flexible Print Circuit; FPC), and is etched on the copper foil surface. The antenna is made on the disc-shaped film; the antenna is made on the disk-shaped film of the base material sheet, and the antenna can be completed by electronic circuit soft board processing.

Another object of the present invention is to provide a tape-type electronic label for operating room equipment, wherein the base material sheet and the covering film are both soft rubber sheets made of polyimide (PI), so that When the electronic tag is used on operating room instruments, the high-temperature resistance properties of the base material sheet and the covering diaphragm material allow the electronic tag to be used for high-temperature sterilization and disinfection along with the operating room instruments.

Another object of the present invention is to provide a tape-type electronic tag for operating room equipment, wherein the disc-shaped film of the base material sheet is rectangular, and the antenna is built around the center periphery of the surface of the disc-shaped film. Loop loop, the pair of guide loops extending parallel to each other toward the central position of the disc-shaped film surface relative to the strip-shaped film segment, and forming a slot toward the resonance hole slot of the strip-shaped film , so that when the strip of tape is wrapped around and pasted on the surface of the operating room instrument, the notch of the resonance hole slot can be naturally approached to the operating room instrument for simple operation, so that the electronic tag can easily be effective or not on the operating room instrument. Effects of incorrect installation.
