Description

Operating room stick-type instrument electronic identifier

This creation is related to a stick-type instrument wireless identifier for operating rooms that can be easily, stably and reliably installed on the rod of a metal instrument and has an external electronic reading device with good and stable reading effect.

Today's medical institutions are constantly striving to improve the quality of medical care to avoid medical negligence; unfortunately, medical negligence is still inevitable. Therefore, the issue of patient safety has always been one of the most important issues of the World Health Organization (WHO), Europe, America, and Japan, and it is also an important issue of the health care service system of countries around the world.

The operating room is indeed a high-risk, high-cost, complex, professional, and high-tech unit. In general, surgery must be performed by a team of surgeons, anesthesiologists, anesthesia nurses, mobile nurses, and other operating room personnel. In the case of medical errors, 16.9% of adverse surgical events were medical negligence. In order to reduce medical errors, negligence and improve the safety of pre-operative care for patients in the operating room, the disinfection and supply department before the operation performs the inventory and distribution of the equipment; the supervision of the use of the equipment during the operation; the recovery, classification, inventory and disinfection of the equipment after the operation The work is of utmost importance. The RFID radio frequency identification technology used in the identification of surgical instruments should be able to bring safety and efficiency to the above work, especially the identification/tracking of surgical instruments before and after use. The hospital can ensure the complete and thorough disinfection, avoid the risk of nosocomial infection, or avoid A medical accident occurred in which surgical instruments were left in the human body.

However, the use of RFID electronic identification tags on today's surgical instruments still has the following problems to be solved:

1. The electronic label on the device is easy to lose:

For surgical instruments to be identified by the RFID system, they must first face how to include a large number of existing instruments in the system management; the existing sticker-type RFID electronic tags on the market generally only rely on glue to attach to the instruments, which are easy to lose during the cleaning and disinfection process. Situation: especially stick-type instruments such as blood aspirator heads, nerve strippers, curettes, laparoscopes, etc. Because the sticks are smooth, it is difficult for RFID electronic tags to be reliably attached to the sticks of the instruments.

2. The electronic tag reading signal is susceptible to interference:

Surgical instruments are mostly made of non-rusting metal materials. Electronic tags (RFID tags) on the market are affixed to the instruments. The transmission and reception of electromagnetic wave reading signals is susceptible to metal interference, resulting in unstable, poor or incorrect signal reading.

Therefore, in order to solve the above-mentioned problems, how to reliably install RFID electronic identification components on existing instruments and have a stable and effective reading effect is actually a technical problem that needs to be solved urgently when using RFID identification systems for surgical instruments.
