Description

[Technical field]

[0001] The present invention relates to an IC tag detection device. [Background technology]

[0002] In the medical field, various medical materials such as medicines are used. Medical materials can be very dangerous if used inappropriately, and many of them have high unit prices. Therefore, in order to prepare appropriate medical fee statements, strict management of the amount, time, and place of use is required. On the other hand, medical procedures, such as surgery, can require the use of large amounts of medical materials in tasks where every second counts. Efficient management of such medical materials is required.

[0003] For example, Patent Document 1 discloses a pharmaceutical management system for managing pharmaceuticals placed on a controlled pharmaceutical tray used in an operating room, the pharmaceutical management system having a first information acquisition means for acquiring first information related to the pharmaceutical removed from the controlled pharmaceutical tray, a second information acquisition means for acquiring second information included in the packaging of the pharmaceutical when the pharmaceutical is used, and a first inquiry means for inquiring about the consistency between the first information and the second information.

[0004] Furthermore, Patent Document 2 discloses an automatic used drug recognition system comprising: a collecting means for collecting storage containers of used injection drugs; a picking means for automatically recognizing the shape and picking position of the storage containers of used injection drugs collected by the collecting means and picking them; a drug information recording means for recording drug information; a drug information reading means for reading, with a camera, the drug information written on the storage container picked by the picking means; and a drug recognition means for identifying the type of drug by comparing the drug information recorded by the drug information recording means with the drug information read by the drug information reading means.

[0006] RF-ID (Radio Frequency Identification) is a system that uses radio waves to read and write data on RF tags without contact. RFID can efficiently scan multiple IC tags. The present inventors have considered using RF-ID to manage medical materials. When using RF-ID for medical materials, the IC tags are stored in a state where they are attached to the packaging of the bag containing the medical materials, and the inventors have considered collecting the IC tags attached to the packaging after use to manage the usage status of the medical materials. Various types of medical materials are used, and the packaging for them also comes in various forms. Meanwhile, each packaging contains many small bags, etc.

[0007] Another example of a case where a large amount of medicines and the like is used quickly is surgery. During surgery, the highest priority is to perform therapeutic treatment, and treatments that require immediate attention are often performed at all times, so collection and management of used packages are often performed after surgery. After surgery, used packages with IC tags attached are collected as waste, and are collected in a large plastic bag or the like in a disorganized manner. In this state, it is time-consuming to collect and organize the IC tags again in order to check the used medicines and the like. For this reason, it is necessary to efficiently detect IC tags even when the medicines and the like are collected in a container or the like. Under such circumstances, the present invention aims to provide a detection device and the like that efficiently detects IC tags attached to packages of medical materials.

[0012] The following is a detailed description of the embodiments of the present invention, but the following description of the constituent elements is one example (representative example) of the embodiment of the present invention, and the present invention is not limited to the following content as long as the gist of the present invention is not changed. Note that in this specification, when the expression "~" is used, it is used as an expression including the numerical values ​​before and after it.

[0013] [Detection device of the present invention] The detection device of the present invention is a medical material detection device having a container for collecting medical material IC tags used in the packaging of medical materials, a housing for accommodating the container, a first antenna for detecting the medical material IC tag arranged on the inner wall of the housing, and a rotating unit for rotating the container within the housing.

[0014] [Detection method of the present invention] The detection method of the present invention is a method for detecting medical materials using a medical material detection device having a container for collecting an IC tag for medical material used in a package of medical material, a housing for accommodating the container, a first antenna for detecting the IC tag for medical material arranged on the inner wall of the housing, and a rotating part for rotating the container within the housing, wherein the package is discarded after the medical material to be packaged is removed, and the detection method comprises the steps of: accommodating the container in the housing with a plurality of the IC tags for medical material collected from the container; and detecting the IC tags for medical material collected in the container while rotating the rotating part.

[0015] According to the detection device and the detection method of the present invention, it is possible to efficiently detect an IC tag attached to a package of a medical material. Note that in this application, the detection method of the present invention can also be performed by the detection device of the present invention, and the corresponding configurations in this application can be used mutually.

[0016] FIG. 1 is a schematic diagram showing an embodiment of the detection device of the present invention. FIG. 2 is a schematic diagram showing an embodiment of a housing etc. used in the detection device of the present invention. The detection device has a container, a housing, a first antenna, and a rotating part. The container is accommodated in the housing. Packages with IC tags attached are collected in the container. A first antenna is arranged around the container in the housing. The container can be rotated by the rotating part in the housing. The rotating part can be rotated by a user turning a handle. The housing is equipped with casters and can be moved. A user sensor is attached to the outside of the housing. The user sensor detects the user.

[0017] The information detected by the first antenna inside the housing and the user sensor outside the housing is received by the receiving unit. The information received by the receiving unit is processed by the control unit. The control unit is also connected to a memory, and can call up information stored in the memory as appropriate or write information to the memory. The control unit can identify the medical material corresponding to the information on the IC tag detected by the first antenna. The control unit can compare the user information detected by the user sensor with the information detected by the first antenna.

[0018] FIG. 3 is a flow diagram showing an embodiment of the detection method of the present invention. Step S11 is a step of storing an IC tag. This storing step can be performed by storing the IC tags for medical materials collected in a container in the housing in a suitable plastic bag or the like. Next, step S21 is a step of detecting the IC tag. When performing this detection, the container is rotated by a rotating part, and the IC tags for medical materials can be detected at multiple times. Next, step S31 is a step of identifying the medical material corresponding to the detected IC tag for medical materials. This allows the IC tags for medical materials stored in the container in the housing to be detected efficiently.

[0019] [Packaging] The package is a package containing medical materials. The shape, material, size, etc. of the package are appropriately adjusted according to the medical materials. The shape of the package may be, for example, a bag or a box. The material of the package may be resin, paper, aluminum vapor deposition, etc.

[0020] [Medical materials] Medical supplies are a general term for medical equipment, instruments, and medicines used in providing medical care. Medical supplies are stored and managed in a packaged state.

[0021] [IC tag] An IC tag has an inlet consisting of an IC (Integrated Circuit) chip and an antenna connected to it. In addition, a protective material for protecting the inlet and a processing material for attachment are combined. Using a corresponding reader, etc., multiple IC tags can be read wirelessly at once using RFID technology. IC tags that use radio waves in the HF band or UFH band can be used. In addition, either active tags or passive tags can be used. Since it is often required to detect multiple IC tags at once, UHF band tags that can be detected from a long distance are preferable. In addition, passive tags can be used because they can be detected using a first antenna in a closed space inside a housing.

[0022] [IC tags for medical materials] The medical material IC tag is an IC tag used in the packaging of the medical material. The medical material IC tag to be detected by the detection device of the present invention can be one recovered from the packaging of used medical materials. The medical material IC tag to be detected may be one peeled off from the packaging, or may be used while still attached to the packaging. Since it is easier to detect each IC tag when multiple IC tags are spaced apart from each other, and the packaging is considered to act as a buffer, it may be detected while still attached to the packaging. When the packaging is an aluminum vapor deposition product that tends to block radio waves, it is more preferable to selectively recover the IC tag portion and reduce the aluminum vapor deposition portion.

[0023] [container] The container is a container for collecting IC tags for medical materials. The container may be rectangular, cone-shaped, cylindrical, or the like. These containers may be used by attaching a plastic bag or the like to which medical IC tags have been collected in advance. These containers may be used in a state in which multiple medical IC tags have been collected. The container may be a cage-shaped container with many open areas or made of resin, so as not to interfere with the radio waves used to detect the IC tags.

[0024] For example, approximately 50 to 200 pieces of medical materials may be used in one surgery, and a container that can collect and store the medical material IC tags from packages that have contained such a number of medical materials can be used.

[0025] [Case] The housing is for housing the container. The housing may also include a first antenna, a user sensor, a rotating part, and the like. The housing may be of a size that is easy for a user to use. For example, the width and depth may be about 30 cm to 1 m, and the height may be about 50 cm to 1.5 m.

[0026] [Electromagnetic shielding] The housing is preferably electromagnetically shielded. When detecting by the present invention, the medical material IC tag to be detected is disposed inside the housing in a state where it is collected in a container. A first antenna for detecting the medical material IC tag is also disposed inside the housing. On the other hand, since the detection device is used in a medical field, there is a possibility that IC tags attached to unused medical material packages are placed around the detection device. In such a situation, in order to selectively detect used medical material IC tags and the like inside the housing without detecting unused items outside the housing, it is preferable that the housing has electromagnetic shielding properties. This electromagnetic shield may be of a so-called waterproof level and may not leak light. As a material, a metal with excellent conductivity may be used. In addition, a radio wave mesh curtain or the like may be used in combination with the lid of the opening used for inserting and removing the container, if necessary.

[0027] The housing may have a door that opens and closes to accommodate the container. The housing may also have a door-closed sensor for detecting that the door of the housing is closed. By using the door-closed sensor, it is possible to confirm that the door is closed when detecting the medical IC tag. If the door is used with the door open, there is a risk of erroneously detecting other medical material IC tags in the medical field outside the housing. In particular, when the housing has electromagnetic shielding properties, the electromagnetic shielding performance may not be fully exhibited if the door is left open, so it is possible to reliably know that the door is closed. For example, a contact displacement sensor, a photoelectric sensor, a laser sensor, etc. may be used as the door-closed sensor.

[0028] [First antenna] The first antenna is disposed on the inner wall of the housing. The first antenna is for detecting IC tags for medical materials. The first antenna is used in combination with a reader to detect weak radio waves generated when the tag resonates with and reflects radio waves sent from the reader, so that the reader can read them again. For this reason, the IC tags for medical materials and a reader that corresponds to the first antenna are also disposed inside the housing.

[0029] The first antenna is preferably arranged around the container so that it can be detected from a plurality of different directions relative to the container. The number of first antennas can be two, three, four, five, etc. The radio waves of the medical material IC tag also have directivity, so it may be difficult to detect depending on the direction, position, distance, and angle. For this reason, it is preferable to provide a plurality of first antennas inside the housing. The housing can be mainly rectangular parallelepiped. In such a rectangular parallelepiped shape, the antennas can be arranged in an L-shape, such as on the side and back, or on the side and bottom, or can be provided on three surfaces, such as the side, back, and bottom. Note that even if an excessive number of antennas are provided, the detection accuracy will not be improved any further, and the cost may increase, or the reading speed and reading accuracy may decrease. From these points of view, it is preferable to provide three first antennas, one on the side, back, and bottom.

[0030] [Rotating part] The rotating part rotates the container in the housing. The rotation by the rotating part may be automatic or manual. Even a half to one rotation changes the relative position with respect to the first antenna, so that the IC tag for medical materials can be detected efficiently. The rotating part in the housing of FIG. 1 and FIG. 2 can rotate the container by rotating a handle attached to the axis of the rotating part in a horizontal plane with the vertical axis as an axis. The rotation speed of the rotating part can be about 10 rpm to 120 rpm or about 20 to 60 rpm in terms of the number of rotations. Some RFID readers can detect tens to hundreds of RFIDs per second by using ones with a simultaneous response adjustment function, so that the IC tag for medical materials can be detected in various directions and angles by detecting for about several seconds while rotating at such a number of rotations. The number of rotations is preferably about half to 100 rotations, and may be about 2 to 20 rotations.

[0031] The specific process for detecting IC tags for medical materials is as follows: the package is disposed of after the medical materials to be packaged have been used, and the container with the multiple IC tags for medical materials collected therein is housed in a housing in a housing process. Next, the rotating part is rotated to detect the IC tags for medical materials collected in the container.

[0032] The housing may have a rotation sensor therein for detecting that the rotating part has rotated. The rotation sensor can confirm that the rotating part has been rotated when detecting the medical material IC tag.

[0033] [Identifying IC tags for medical materials] Product information is written and stored in the medical material IC tag by a writer corresponding to the used IC tag. This stored product information may be information provided at the time of shipping the medical material. Alternatively, individual master information for the site of use that matches the "written data in the medical material IC tag" and the "details of the medical material" data for each hospital or department in the medical site where the detection device is used is prepared, and the medical material IC tag can be identified based on the individual master information.

[0034] Information from the medical material IC tag detected using the first antenna inside the housing is transmitted from the transmitter by a reader or the like used in the housing and received by a receiving unit for data processing connected to the control unit, memory, and display unit.

[0035] [Control Unit] The control unit performs control for identifying the medical material IC tag detected using the first antenna, and for this purpose, for example, compares the information of the medical material IC tag detected in the housing with the master information stored in the memory to identify the medical material to which the medical material IC tag was attached.

[0036] [Memory] To recognize that the ID tag is a medical material to be managed, a master table is used to identify the medical material corresponding to the product ID written in the EPC area of ​​the IC tag and the information written in the user area. The memory can store information from this master table, information on the medical material IC tag detected when using a detection device, etc., and the results of identification by comparing the master table with the medical material IC tag detected by the detection device, etc.

[0037] [Display] Information for operating the detection device and the detection results of the IC tags for medical materials can be displayed on a display unit such as a monitor. The display unit may further be capable of displaying any information, such as a warning when an abnormality is found in the detection results.

[0038] [Operation section] The detection device has an operation unit for setting and operating the detection device. The operation unit is attached to the housing and can be a combination of buttons, a keyboard, a mouse, a touch panel, etc., which are operated when starting or ending detection.

[0039] These control units, memories, display units, and operation units can be realized by incorporating, for example, personal computers, smartphones, tablet terminals, servers, clouds, etc., either alone or in combination, as programs or application software.

[0040] [User] The user is someone who uses a detection device. The detection device identifies who performed the check for disposal of the medical materials, and uses the results to determine whether proper disposal has been performed and as basic information for creating a medical fee statement. For this reason, it is preferable that the detection device of the present invention is also capable of identifying the user when identifying the medical material IC tag.

[0041] [User sensor] The user sensor is an antenna for detecting a user of the detection device. The user places a container in the housing and operates the handle of the rotating part. For this reason, it is preferable to attach the user sensor to the housing. Also, the housing can be provided with an electromagnetic shield or the like to distinguish the detection from the IC tag in the internal container. For this reason, it is preferable to attach the user sensor to the outside of the housing, such as on the top or side of the housing.

[0042] [User Identification Information] Any method can be adopted for identifying user information to identify the user with the user sensor. For example, biometric authentication such as face recognition, fingerprint, or iris, an IC tag worn by the user, or an identification code entered by the user can be used. Preferably, a user IC tag, which is an IC tag worn by the user, is used, and the user sensor is an antenna combined with a corresponding RFID reader. It is preferable to obtain the user's identification information multiple times when the detection device or the like is used. The RFID technology adopted for the user IC tag is preferably a close contact type, a proximity type, a nearby type, or the like, in order to identify a user who is near the detection device.

[0043] 4 is a flow diagram showing another embodiment of the detection method of the present invention, which also utilizes user information.

[0044] Step S12 is a step of storing the IC tags. This storing step can be a step of storing the collected medical material IC tags and the like in a container in the housing, such as a suitable plastic bag. Next, step S22 is a step of identifying user information, which is performed by acquiring user identification information using a user sensor attached to the detection device, and identifying the user based on the identification information.

[0045] Step S32 is a step for determining whether the user is appropriate. If the user is inappropriate, such as if the user cannot be identified or is not registered, detection of the medical material IC tag is stopped.

[0046] If the user is appropriate, a step of detecting the medical material IC tag is performed in step S42. When performing this detection, the container is rotated by a rotating part, and the medical material IC tag can be detected at multiple times.

[0047] Step S52 is a step of detecting the user information again. By detecting the user information multiple times together with the medical material IC tag, it is possible to obtain reliable information that the user actually used the detection device.

[0048] Step S62 is a step of matching the detected medical material IC tag with the corresponding medical material. This makes it possible to efficiently detect the medical material IC tag contained in the container inside the housing. Furthermore, user information can also be obtained as highly reliable information. This information can be used as more reliable information for medical billing.

[0049] Although an example has been described here in which steps S22 and S32 are performed before step S42, the steps may be switched so that step S42 of detecting the IC tag is performed first, and then steps S22 and S32 of identifying user information, etc. are performed later. Also, when the user is not appropriate, the detection may not be stopped, and the results of the user information may simply be stored.

[0050] The method may further include a step of checking the state detected by the door closing sensor and / or the rotation sensor in the state checking unit. If the state checking unit detects the medical material IC tag and the door closing state or the rotation state is not appropriate, the state is deemed to be inappropriate, and the detection may be stopped or a warning may be displayed.

[0051] FIG. 5 is a table showing an outline example of detection of medical materials by the detection device of the present invention. When an IC tag is detected with a specific detection number using a detection device, the EPC area and user area information for identifying the IC tag are compared with the master information to identify the specific medical material. The detected IC tag can be recorded along with information on how it was detected in the detection device, the time it was detected, and the orientation of the rotating part at the time of detection.

[0052] In addition, the user information of the detection device at the time of the detection can also be acquired. The information on medical materials can also be used in comparison with information on whether or not there was a planned use for surgery, etc., which is set by the user. For example, it is possible to check whether packages of medical materials that are not planned to be used have been collected, or whether there are medical materials that were planned to be used but have not been collected. By appropriately warning the situation of such items that have not been properly processed, it is possible to contribute to the proper management of medical materials.

[0053] In this way, by matching the reading time of the medical material with the detection time of the user, it is possible to know whether the detection device reads the information or whether the information was added later without using the detection device. Also, if the purpose is to improve the accuracy of information and provide a security solution, security can be improved by limiting the users who are registered.

[0054] In addition, by being able to distinguish whether the data read in regarding medical materials or users is from a detection device or data that was later manually added to the management software from a PC, it is possible to determine when the input information is incorrect and to identify intentional corrections.

[0055] Match The detection device may have a collation unit that compares a first time when the first antenna detects the medical material IC tag with a second time when the user sensor detects the user. The collation unit may perform a step of checking the consistency between the first time and the second time.

[0056] The detection device of the present invention is rotated by a rotating part, so detection is performed at multiple times. Therefore, by acquiring the user's identification information multiple times in accordance with the above, it is possible to reliably grasp that the user has performed the work. In other words, the time when the first antenna was used, the time when the user sensor was used, and the information on the IC tag etc. acquired using each antenna are acquired together, and these are appropriately recorded in memory, and the results are compared to see if they are within an appropriate range.

[0057] The information detected by the detection device of the present invention can be used as information for medical billing for medical materials used in surgery, etc. It can also be used for replenishing and ordering medical materials that have been used.

[0058] Furthermore, the detection device can have the ability to identify and input patient information, add information on materials that could not be read by other means such as manually, and communicate with equipment such as a higher-level server that stores master data for the entire hospital.

[0059] [Test example] The following is an outline of the tests carried out to obtain the knowledge of the present invention. The effects on reading of the container when the container is stationary or when the container is rotated during reading were confirmed.

[0060] As shown in Figure 2, an attempt was made to detect IC tags (medical material IC tags) affixed to the packaging of medical materials using a container attached to the rotating part and a housing with an antenna placed around it. Label tags were used for packaging other than aluminum-deposited products. Flag label tags were used for packaging of aluminum-deposited products. A specific low-power radio station (250 mW) was used as the RFID reader. An RFID reader / writer (UHF band) was used as the reader. A combination of an RFID circularly polarized antenna and a rectangular antenna for the gate was used as the antenna. The antennas were placed in three places on the side, back, and bottom of the container.

[0061] The medical supplies included 89 items of 59 categories (including 4 small boxes, 2 aluminum-coated boxes, and the rest wrapped in plastic bags). The medical supplies included syringes, needles, tubes, surgical gloves, tube connectors, stopcocks, skin staples, harmonic scalpels, catheters, gel pads, tissue stabilizers for internal fixation, trocars, wrap bases, wrap shields, balloon trocars, air seals, air filters, catheter mounts, anesthesia masks, X-ray gauze, infusion sets, vessel fusers, suction reservoirs, guidewires, stents, local anesthesia packs, and general surgery kits. The information identifying the medical supplies, such as the manufacturer and product name, was recorded in advance on IC tags affixed to the packages that contained the medical supplies, and the master information for the corresponding medical supplies was stored in memory before the evaluation.

[0062] Figure 6 is an image of an IC tag for medical materials inside a container. Figure 6(a) is an image showing an example of an IC tag attached to the packaging of medical materials. Figure 6(b) is an image showing the state in which the IC tag for medical materials has been collected into a large plastic bag. Figure 6(c) is an image showing the state in which the plastic bag of Figure 6(b) has been placed inside a container inside a housing. After this, the lid of the housing was closed and the IC tag for medical materials was detected.

[0063] When the antenna was placed in three directions and read in a stationary state, 85 out of 89 were detected. After that, by manually rotating the antenna and reading, all 89 were read. [Industrial Applicability]

[0064] The detection device of the present invention is an invention of a product, and the detection method of the present invention is not a method for surgery, treatment, or diagnosis of humans. The detection device of the present invention can be used for the management of medical materials after use, and is therefore industrially useful.
