Description

Acupuncture needle wireless identification structure

The present invention relates to a wireless acupuncture needle identification structure that is resistant to metal interference and has long-distance reading and identification capabilities.

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

Acupuncture treatment covers a wide range. According to the first edition of the World Health Acupuncture Special Issue published by the World Health Organization (WHO) in 1980, there are 43 diseases that are proposed and recommended to be treated with acupuncture worldwide. In November 1996, the World Health Organization (WHO) Milan Conference in Italy approved 64 acupuncture indications, including digestive system diseases, endocrine metabolic diseases, gynecological diseases, neuropsychiatric diseases, motor system diseases, etc.

Acupuncture is a method of inserting needles into the subcutaneous tissue or muscles at specific locations on the human body surface to treat various diseases or relieve pain. Whether it is acupuncture treatment or acupuncture pain relief, the needles must be used to directly contact the internal tissues of the human body, so the hygiene and safety of the needles themselves are very important. If the needles used to treat diseases are not hygienic enough and are infected with unnecessary pathogens, secondary injuries will be caused. In order to avoid the reuse of disposable needles, the management of needle recycling and waste inventory is very important. RFID wireless radio frequency identification technology is used for needle identification, which should bring safety and efficiency to the above work, especially identification/tracking of needles before and after use. Hospitals can ensure the implementation and thorough execution of recycling and inventory work, avoid the risk of hospital infection, or avoid medical accidents where needles remain in the human body.

Conventional disposable acupuncture needles are usually made of stainless steel, and the needle body is extremely thin. Even at the needle handle, most of the diameters are only about 1.2 mm, making it difficult to use RFID tags on the needles. In particular, if multiple needles are to be identified over a long distance at the same time (to increase needle identification efficiency), the shape or space of the needles will be limited. It will be difficult to build an ultra-high frequency radio frequency antenna and the antenna electromagnetic wave signal transmission and reception is easily interfered by metal. It is even more difficult to use ultra-high frequency wireless radio frequency identification chip (UHF RFID) technology to achieve the above requirements.

The main purpose of the present invention is to provide a wireless identification structure for acupuncture needles, wherein the front end of an acupuncture needle has a needle tip and the rear end has a needle handle, and an electronic tag is installed on the needle handle. The electronic tag includes:

A substrate sheet is a strip of flexible insulating film, which is composed of a thickened section connected to a sensing section at one end to form a whole tape sheet body. The tape sheet body has a tape inner surface, and the tape inner surface is backed with adhesive. The tape sheet body is rolled and adhered to the outer diameter surface of the needle handle. The distance between the outermost edge of the sensing section after rolling and the outer surface of the needle handle is defined as the isolation thickness;

An antenna is a metal film antenna made on the surface of the sensing section of the substrate sheet, having a perforated groove, and a slit-shaped notch is provided on one side of the perforated groove, so that the antenna forms two poles of a loop on both sides of the slit-shaped notch, and the two sides of the slit-shaped notch serve as pads;

A wireless radio frequency identification chip is disposed on the pad of the antenna and electrically connected to the two poles of the antenna loop;

When the acupuncture needles with the electronic tags are taken out from the storage, the identification is read by the activation reader to start the control, and after the acupuncture needles are used, they are collected and sent to the waste place, and the identification is confirmed by the reader to confirm that they are all recycled; the overall inventory and control process, the electronic tags on the acupuncture needles, through the isolation thickness of the tape sheet of the substrate sheet after winding, the antenna is separated from the acupuncture needle by a gap, Including, the tape sheet is wound around the expanded sensing section to fully unfold the antenna, so that the loop formed by the perforated slot of the antenna can be used to resonate with the electromagnetic wave signal reflected from the acupuncture needle, so that the activated reader or point receiving reader can stably read the ID identification code of the wireless radio frequency identification chip against metal interference, and obtain the effect of long-distance reading and identification of the acupuncture needle identity.

The second purpose of the present invention is to provide an acupuncture needle wireless identification structure, wherein the substrate sheet is a metal foil soft board, and the antenna is directly manufactured on the surface of the sensing section through etching of the metal foil surface; so that the antenna manufactured on the substrate sheet can be easily processed by an electronic circuit soft board.

Another purpose of the present invention is to provide an acupuncture needle wireless identification structure, wherein the isolation thickness of the tape sheet of the substrate sheet wound around the needle handle is at least 0.4 mm, so that the antenna can be made of an electronic circuit board commonly used in the market as the substrate sheet, and the antenna and the acupuncture needle can have a sufficient distance to prevent interference.

Another purpose of the present invention is to provide an acupuncture needle wireless identification structure, wherein the tape sheet of the substrate sheet is connected to a sensing section at one end by a thickened section, and a covering section is extended from the other end of the sensing section, and the covering section is wrapped around the sensing section and adhered to cover the antenna and the wireless radio frequency identification chip, so that the antenna and the wireless radio frequency identification chip can be isolated and protected from the outside world.

Another purpose of the present invention is to provide an acupuncture needle wireless identification structure, wherein the tape sheet of the substrate sheet is wound and adhered to the needle handle, and a shrink sleeve that completely seals the electronic tag is placed on the outermost surface of the wound tape sheet; so that the antenna and the wireless radio frequency identification chip can be isolated and protected from the outside world, and the installation fixity of the electronic tag on the needle handle is increased.

In order to achieve the above-mentioned purpose, the present invention specifically provides a preferred embodiment and is described in detail with reference to the attached drawings as follows:

A wireless identification structure for acupuncture needles, as shown in Figures 1, 2, 3, and 4, is an acupuncture needle 10 having a needle tip 12 at the front end of the needle body 11 and a needle handle 13 at the rear end. The needle handle 13 is equipped with an electronic tag 20, and the electronic tag 20 includes:

A substrate sheet 21 is a strip-shaped flexible insulating film, which is composed of a thickened section 210 connected to a sensing section 211 at one end to form a whole tape sheet 21A. The tape sheet 21A has a tape inner surface 212, and the tape inner surface 212 is backed with glue. The tape sheet 21A is rolled and pasted on the outer diameter surface of the needle handle 13. The distance between the outermost edge of the sensing section 211 after rolling and the outer surface of the needle handle 13 is defined as the isolation thickness T;

An antenna 22 is a metal thin film antenna made on the surface of the sensing section 211 of the substrate sheet 21, having a perforated groove 220, and a slit-shaped notch 221 is provided on one side of the perforated groove 220, so that the antenna 22 forms two poles of a loop on both sides of the slit-shaped notch 221, and the two sides of the slit-shaped notch 221 serve as pads 222 (Pad);

A wireless radio frequency identification chip 23, which is an ultra-high frequency wireless radio frequency identification chip (UHF RFID), is disposed on the pad 222 of the antenna 22 and electrically connected to the two poles of the loop of the antenna 22;

When the acupuncture needle 10 containing the electronic tag 20 is taken out from the storage place, the identity is read by the activation reader (not shown) to start the control, and the acupuncture needle 10 is collected to the waste place after use and the identity is confirmed by the receiving reader (not shown) to confirm the complete collection; the overall inventory and control process, the electronic tag 20 on the acupuncture needle 10 is isolated from the acupuncture needle 10 by the isolation thickness T of the tape sheet 21A of the base sheet 21 after being wound. The gap between the segments includes that the sensing segment 211 after the tape sheet 21A is rolled up and expanded fully unfolds the antenna 22. In this way, the loop formed by the hole slot 220 of the antenna 22 can be used to resonate with the electromagnetic wave signal reflected from the acupuncture needle 10, so that the activation reader (not shown) or the point receiving reader (not shown) can stably read the ID identification code of the wireless radio frequency identification chip 23 against metal interference, and obtain the long-distance reading and identification effect of the identity of the acupuncture needle 10.

According to the above-mentioned embodiment, as shown in Figures 1 and 3, the substrate sheet 21 is a metal foil (such as copper or aluminum foil) soft board, and the antenna 22 is directly manufactured on the surface of the sensing segment 211 through etching of the metal foil surface; so that the antenna 22 manufactured on the substrate sheet 21 can be easily manufactured using an electronic circuit soft board.

According to the above-mentioned embodiments, as shown in FIGS. 1, 2, and 4, the isolation thickness T of the tape sheet 21A of the substrate sheet 21 wound around the needle handle 13 is at least 0.4 mm, so that the antenna 22 can be made of a commonly used electronic circuit board (thickness of about 0.2 mm) as the substrate sheet, and the antenna 22 and the acupuncture needle 10 can have a sufficient distance to prevent interference. The RFID system uses a frequency band of 922-928 MHz. As an example, the electronic tag 20 is set on the handle 13 of the stainless steel acupuncture needle 10 as shown in FIG2. Through the reading distance test, as shown in FIG10, the measured theoretical reading distance is 0.65-0.68 m (meter), which proves that the electronic tag 20 is set on the handle 13 of the stainless steel acupuncture needle 10 and is not affected by the acupuncture needle. The metal material of the needle 10 interferes or affects the needle 10; and the actual reading distance (due to the increase in equipment power) is 1.5 times the theoretical reading distance on average, indicating that the electronic tag 20 is set on the handle 13 of the stainless steel acupuncture needle 10, and the reading distance in the 922~928MHz frequency band can reach 0.97~1.05m (meters), which meets the needs of the hospital's disposable needle use and recycling (discarding) field.

According to the above embodiment, it is feasible that, as shown in Figures 5 and 6, the tape sheet 21A of the substrate sheet 21 is connected to a sensing section 211 by a thickened section 210 at one end, and a covering section 213 is extended from the other end of the sensing section 211, and the covering section 213 is wrapped around the sensing section 211 and adhered to cover the antenna 22 and the wireless radio frequency identification chip 23, so that the antenna 22 and the wireless radio frequency identification chip 23 can be isolated and protected from the outside.

According to the above embodiment, preferably, as shown in Figures 7, 8, and 9, the tape sheet 21A of the substrate sheet 21 is rolled and adhered to the needle handle 13, and a shrink sleeve 30 (such as a heat shrink film sleeve) is placed on the outermost surface of the rolled tape sheet 21A to completely seal the electronic tag 20; so that the antenna 22 and the wireless radio frequency identification chip 23 can be isolated and protected from the outside world, and the installation fixity of the electronic tag 20 on the needle handle 13 is increased.

The above description is only illustrative and not restrictive of the present invention. Persons skilled in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined in the attached specification, but they will all fall within the scope of protection of the present invention.
