To achieve this, it includes radiopaque marker material configured to appear in MRI images. obtain.

[0047] HCP tracks the surgical sponge 10 before, during, and after the surgical procedure. Ensure that Pongee-10 is not inadvertently left behind or abandoned in patients. This is important. Therefore, as mentioned above, RFID tags 20 are used in surgical procedures. The location and number of sponges used can be identified. RFID tags 20 can be used in surgery. The absorbent material body 11 can be bonded to the upper surface of the sponge 10, adjacent to the edge or corner. Although not shown, the RFID tag 20 is located inside the handle, between layers of absorbent material, or during surgery. It is intended that the sponge 10 can be incorporated in any way into other parts of it. For example The RFID tag 20 is attached to or embedded in the handle, or in the surgical sponge 10. It can be combined with other parts.

[0048] The detection element of the RFID tag 20 can be used in conjunction with a multiplex detection system. 20 may include a capacitor and an antenna (not shown), which are leaders The RFID tag 20 receives power from its detection antenna (RFID antenna) and condenses Charge the capacitor. This capacitor will power the operation of the unpowered RFID tag 20. The RFID tag 20 has a reading function, a carrier frequency modulation function, and an imprinted code. The integrated circuit may include a read-only memory section equipped with a detection element. The integrated circuit and corresponding antenna are enclosed in a blood, water, or saline solution-resistant enclosure. It is encapsulated in a sterilizer. Therefore, the RFID tag 20 can withstand repeated sterilization. It can be attached to other surgical instruments such as metal instruments that can be sterilized and reused multiple times. It can be done. Depending on the carrier frequency and the type of RFID tag 20, RFID Tag 20 differs significantly in cost, size, and resistance to shielding by intervening tissue. There is a possibility that this will happen.

In addition to counting or identifying the sponges 10, the location of the surgical sponges 10 is detected. The goal is to achieve this dual objective. Therefore, a particular RFID tag 20 is detected It can function as both an element and an aggregation element. RFID tags are detected by the reader. In cooperation with the terminal, the position of the surgical sponge 10 is detected, and the unique identification of the surgical sponge 10 is performed. Provides data for determining other information. RFID tag 20 operates above the MHz range. It is possible. An example frequency range is approximately 13.35 to 14.15 MHz (high frequency). The range of 850 to 950 MHz (ultra-high frequency), or the microwave frequency range (i.e.) These RFID tags can include frequencies from 2.45 to 2.55 GHz. The additional bandwidth provided will allow the surgical sponge 10 to respond within a short time within the question zone. This can increase the probability of detection and discovery.

(Tyvek) (registered trademark) pouch, rigid pouch with poly Tyvek (registered trademark) cover. It may include a sieve or similar containment device. Any number of surgical sponges 10, Alternatively, surgical instruments may be packaged by strap 38 or in container 50. To be bound together, or to be bundled together.

[0054] Bundling or packaging the surgical sponges 10 as described above is done in bundles 30 This creates a challenge in scanning the RFID tags 20 on each individual surgical sponge 10 contained within. There is a possibility that the RFID tag 20 on the surgical sponge 10 will be attached when packaged. When attempting to scan, one potential challenge is the high likelihood of interference between RFID tags. This can lead to inaccurate counting of surgical sponges 10, or a shortened detection distance. It is possible. The sterility of surgical tools and instruments must be maintained, RFI The D-reader may not be sterilized or may not be usable in a sterile field. Providing sufficient detection distance is important for surgical tools and instruments. If the distance is insufficient, the HCP will add a sterile drape for the scanner before each surgery. This requires spending time and incurring additional costs. On the other hand, densely packaged To overcome the challenges of surgical instruments with RFID tags, simply increase the scanner output. Then, surgical sponges are transported or stored nearby, including in adjacent operating rooms or other storage areas. Undesirable aggregation of the range may occur. It is not intended for use in any external treatment. Attempts have been made to calculate the cost of medical instruments, but their active use in surgical procedures is not intended. Accidental counting of missing surgical instruments wastes time for the HCP and prolongs the duration of the surgical procedure. It could be the cause.

[0055] A system 100 for managing surgical instruments during surgical procedures is illustrated in Figure 2. System 100 communicates with surgical instruments equipped with RFID tags and checks the inventory of surgical instruments. Hardware and software for creating and maintaining database records to manage. This includes the type number of those surgical instruments that are made available for use in specific surgical procedures. This includes identifying the type and a unique identification number. System 100 uses HCP to determine the data Enter the information into the database, and record that information in the database before, during, and after the surgical procedure. It also provides an interface for accessing other information.

[0056] System 100 includes a system computer 101 that communicates with the display 102. The display 102 is a touchscreen 104 or other input hardware (not shown). It may also include an integrated display such as a tablet computer (without further addition). In the alternative, the display 102 is simply the system computer 101 and the display A monitor with input capabilities provided by other hardware that communicates with I-102. Obtain. Other input hardware (not shown) is a microphone for voice command control. or may include a video camera or other sensors for providing gesture control. Other alternative input hardware includes trackballs, touchpads, keyboards, and mice. It may include things like that.

[0057] The display 102 can be supported on a base 106. As shown in Figure 2, The S106 can be mounted on a pole. In another alternative, the base 106 can be mounted on a mobile cart. Alternatively, it may be a fixed unit. Base 106 is a display such as a tablet computer. The game itself features an integrated display that includes all power, computing, and input functions. The base 106 may be a mechanical support for the display 102. Alternatively, the base 106 may be a display It can support features not integrated within the display 102. For example, base 10 6 supplies power to the system computer 101 and the display 102. The base 106 may include a rechargeable battery for supplying power to the system 100. Central processing unit, memory device, data storage device, system computer It can accommodate other hardware for 101.

[0058] Base 106 also communicates with an RFID reader 108 that communicates with the system computer 101. This can be supported. The RFID reader 108 is integrated into the base 106, or It is detachable and can be operated remotely from base 106. Base 106 is handheld Dot for removable portable RFID readers such as Dot RFID Reader 108 It can provide a . When docked to base 106, the RFID reader is It can rely on its own external power supply and communicate with the system computer 101. A wired dock connection can be used for this purpose.

[0059] The RFID reader consists of RFID reader 108 and RFID tags (surgical sponge 10). It may include an RFID transceiver that enables communication between (tag 20, etc.) and R The RFID reader 108 has its own power supply, data processing, and may include memory or data storage devices. RFID reader 1 08 can be configured to operate with various levels of power supplied to the RFID transceiver. It is capable of changing the effective output of radio energy from the antenna.

[0060] System 100 includes an external computing device 110, or an external computer It can communicate with the computing device 110. This includes additional memory or data storage. Garage may be included. Device 110 is a hospital network or internet server. Wireless connections of other systems such as routers or modems for communicating with remote resources such as It can provide continuation. In other alternatives, the network connection is external device 110 It is integrated into the system computer 101 without requiring any additional components.

[0061] System 100 can be provided in a surgical environment such as a hospital operating room. It can be adapted to be draped for placement in a sterile field. Furthermore, System 100 is located adjacent to the sterilization field but outside of it, and sterilization The need for drapes can be avoided. A further alternative is to sterilize Base 106. Although it can be placed outside the field, the mobile RFID reader 108 is based on 1 It is isolated from 06 and, as is known in the art, by appropriate sterile draping or other methods. It can enter the sterilization field using a bacterial maintenance device.

[0062] System 100 is a hand tagged with an RFID tag that should be managed during surgical procedures. A stock of surgical instruments 112 can be maintained. In Figure 2, the stock of surgical instruments is a surgical sponge 10 Drawer 1 containing supplies of several different types of RFID-tagged surgical instruments. Illustrated as a mobile cabinet or cart equipped with 14. As described above, The surgical sponges 10 are packaged or bundled in various quantities. RFI D-tagged surgical sponge 10 ranges from a minimum of 2 inches x 2 inches to a maximum of 8 inches x 108 inches. They are available in various shapes up to inches. Depending on the number of layers that make up a single surgical sponge 10 There is also variation in thickness. For example, some surgical sponges 10 have a minimum of 4 plies (pl y) or up to 32 plies. Most commonly, surgical sponge 10 is single Up to 10 units are packaged inside the package.

[0063] Each surgical instrument, for example, a surgical sponge 10, is uniquely identified as an individual item. This provides data for that purpose, as well as other relevant information for managing the inventory of surgical instruments. The data is tagged with an RFID tag, for example, tag 20. See Figure 3 here. An example identification scheme 120 that can be stored in the RFID tag 20 is illustrated. Various tag and data encoding schemes are currently available, including identification scheme 120. This explanation is not intended to be limiting. Generally, RFID tags are RFID integrated circuits ( Manufactured using a tag identification (TID) 122 assigned by the manufacturer of the IC. This TID122 is usually stored in a write-once memory location and read from the IC. Also known as a dedicated memory location. TID12 provided by the tag manufacturer. In addition to point 2, other information may be associated with specific surgical instruments such as surgical sponges 10. It may be provided in relation to attaching it.

[0064] The identification scheme 120 identifies the type of surgical instrument to which it is tagged, namely sponge. It may include a dedicated portion 124 to identify the type ID. One alternative is a sponge. Type ID 124, as described above, the quantity of sponges of that sponge type, user input The name displayed on the surface, and the RFID reader used to count the types of sponges. Further specifications related to the sponge type, such as the power level specified for operation. In order to search for information, the system computer 101 is used in combination with a lookup table. Therefore, it is a value that can be used. The lookup table is data from integrated display 102. Data storage, data storage provided to base 106, external computer devices Locally to the system computer 101, such as the data storage 110, and This includes the hospital network and the location of internet servers, etc., system computer 101 It can be stored remotely. In other alternatives, sponge type ID124 looks up It can be encoded to directly provide specific information without requiring correlation with table values. For example, sponge type ID124 is a specified R associated with a particular type of sponge. It can directly correspond to the FID reader power level. In either case, sponge type ID12 4 corresponds to the power level parameters stored in the RFID tag associated with the sponge type. It is possible. The power level parameter can be either directly encoding the power level value in dBm, or power, electricity. Control or change current, voltage, or direct or indirect power output from the leader's antenna. It can provide data corresponding to other settings of the adjusting leader. Sponge type ID124 is a sponge type that will be explained in more detail below. RSS related to minimum read intensity for counting surgical instruments in surgical procedures It can be correlated with or encoded by the I threshold.

[0065] Identification scheme 120 includes the sponge package, the number of sponges inside the package, and This may include information that helps identify where a particular sponge is located within that quantity. For example, the identification scheme includes a unique package ID 126 and sponge number 128. Obtain. Each sponge package contains all the components common to a single package. A unique shared identifier may be assigned. The unique package ID 126 is also unique A specific value within the package ID identifies the package as belonging to a particular type of surgical instrument. It can be encoded to help distinguish or specify. The unique package ID 126 is Furthermore, specific values ​​can be encoded to identify the quantity of sponges within a package. For every 10 sponges in the cage, sponge number 128 is different from the other sponges in the package. They are distinguished. For example, in a package of 10 sponges, sponge number 128 is 1 One sponge, one sponge with sponge number 2, and so on, up to sponge number 128. There are up to 10 sponges. Unique package ID 126 and sponge number 128 are It can also represent the package contents information stored in the tag.

[0066] Identification scheme 120 assigns a unique identifier to the written data and copies it from the previous tag. - As a security measure to ensure that it has not been done, within rewritable memory It may include a read-only copy 130 of the TID. The TID copy 130 may also be used alone. This combines with other data stored in the tag to uniquely identify the tagged sponge. It can serve as a unique identifier for identification. Further potential security As a countermeasure, or as a way to ensure that the data is not corrupted, an identification scheme 120 is a checksum of 134. The data included in the identification scheme on tag 120 All or part of it can be used as input to a mathematical algorithm to generate a checksum value. A specific mathematical algorithm determines that the tag is a sponge manufactured by a first party, To ensure that only sponges manufactured by other authorized parties are uniquely identified. Therefore, it can be owned by the sponge manufacturer. A simple example of a sum is to sum all the values ​​of the other data fields in the identification scheme 120. The sum is divided by a given constant, and the remainder is used as the checksum value. Unauthorized products that do not know the specific constants used in Gorism may have their tag data unverified. As a step in the aggregation process to verify whether this is the case, the system computer 101 performs the following: It is detected.

[0067] The identification scheme 120 is a set of rules for writing to tags during the aggregation or exclusion process. It may include a fixed value. For example, the identification scheme 120 in Figure 3 cuts after the sponge has been excluded from the aggregation. It includes the exclusion bit 132, which is a replaceable flag. This toggle can be used, for example, in aggregation. If an RFID reader operating in exclusion mode excludes data from the total at the end of a surgical procedure, By sending a command to the tag instructing it to change the value of this data field, This can be achieved. This value is achieved when an RFID-tagged sponge completes the normal aggregation procedure. It may be particularly advantageous in emergencies where it is used on patients without being used. Bit 132 is excluded from aggregation. This is a value that can be switched during the procedure, and is used to properly manage the inventory of surgical instruments during surgical procedures. It can be used by the system computer 101.

[0068] System 100 is a surgical instrument such as a surgical sponge 10 and an RFID tag 20. Based on the information stored in FID tags, the inventory of surgical instruments used in surgical procedures is managed. System 100 aggregates and excludes surgical instruments related to specific surgical procedures. A record that stores the information necessary to manage the inventory of surgical instruments, specifically identifying them. It may include a base. In particular, system 100 scans the device with an RFID reader 108. By doing so, the surgical instruments are counted in at the start of the surgical procedure, and the procedure It may be configured to count out surgical instruments at the end of the process. Various package quantities and different types of surgical instruments that may be used in the procedure (for example) To overcome the challenge of having different sponge sizes in one package than in another. Therefore, the RFID reader 108 reads the data stored in the tag or the data stored in the tag. Dynamic power level based on power level parameters retrieved from the lookup table It can be configured to operate with a bell.

[0069] More specifically, system 100 first uses the RFID reader at the default power level. -108 can be operated. This default power level is for RFID readers. It can represent an intermediate value within the range of 108 full operating capabilities. Alternatively, the default power level is Depending on the desired first set of reading results, this can be an extreme value or a low value. For example, Straight In environments close to the device, the default power level is used for the operation of the RFID reader 108. It may be desirable to set the capacity to its lowest extreme value. In this way, system 100 , you won't be overwhelmed by an overly exponential result set. Alternatively, the default power It is desirable to set the level to the highest possible value of the RFID reader 108's operating capability. Yes. In this case, system 100 is the inventory storage area and the sterile area where surgical procedures are performed. They are placed at a greater distance from the ground. Another consideration is the RFID tags 20 and RFID links. Ambient electromagnetic noise in the environment may interfere with consistent communication with the commander 108. It can be a quantity.

[0070] System 100 evaluates the intensity of the response signal received from a specific tag, and the received response An indicator can be assigned that reflects the strength of the answer. In other words, System 1 00 is the backscatter response of the tag in relation to the power level of the initial transmitted signal of the RFID reader. Report the power level of the signal. Use the response signal strength indicator or RSSI to report the R The quality of the response for a specific tag within the FID reader's reading zone can be evaluated.

[0071] When the RFID reader 108 is operated at the default power level, system 100 The RFID reader 108 receives a response output signal from the RFID tag 20 within its effective range. In one configuration, these signals include the RFID tag 20 to which the tag is attached. The unique identifier, power level parameters, and package contents information of the surgical instrument are included. Yes. System 100 selects such a first response and the default power level is Reconfigure RFID reader 108 to operate with different power level parameters for the first response. It can be configured. Once reconfigured, system 100 will have an RFID reader 108. It operates at a first power level and receives a first set of responses at the first power level. Within the response set, there are responses to the operation of the RFID reader 108 at a first power level. Each RFID tag 20 contains a unique identifier, package contents information, and power level parameters. The data is included. The first response set is the RFID reader at the default power level. By comparing it with the package contents information from the first response selected in response to the action, System 100 has a complete first package for checking in for surgical procedures. You can decide whether to do it or determine the error state. This series of steps This can be repeated until all desired surgical instruments for a particular surgical procedure are collected. ru.

[0072] In one alternative, for a specific RFID reader power, system 100 is spon These tagged tags provide a sufficiently strong response signal compared to RSSI associated with the type. It can be configured to aggregate only the devices. For example, an RFID reader at a specific power level When operated, it can generate numerous responses representing instruments stored nearby. Surgical instruments By requiring a minimum RSSI for item aggregation, the RFID reader is not specifically required for aggregation. Only these surgical instruments presented will be tallied and made available for actual surgical procedures. Also, other nearby devices will not be unintentionally included.

[0073] Check the package integrity during the check-in process to avoid HCP confusion. Ensure that the appropriate and expected quantity and type of sponge are available for the surgical procedure. It is important to actually do this. System 100 puts the first response set into the first package. By comparing with the information, we can confirm that all expected surgical instruments are actually present. We are verifying this. For example, we select the first response and then re-apply it to the associated first power level parameter. When configuring, system 100 has a power level parameter specified for its sponge type. If there are fewer items than the total contents of the package when asked about the contents of the package. It is configured to determine the error state. Power level parameters are, for example, package The number of sponges included in the packaging, and the size of materials that may interfere with the effective communication of wireless signals. The thickness and other factors are specially adjusted to suit specific sponge types depending on the packaging configuration. Specifically, the power level parameter of the sponge type is used for RFID reader 108. The distance between the package of surgical instruments presented for calculation is the first distance D1. Selected to maintain a preferred reading distance that is larger and smaller than the second distance D2. In the first example, the space defined between the first distance D1 and the second distance D2 is a Lie. To configure a preferred reading range for surgical instruments away from the dart, maintain sterility, or Storage near System 100 due to packaging or handling by HCP Minimize the impact of the number of sponges used. For example, measure from an RFID reader The first preferred distance D1 is approximately 12 inches, and the second preferred distance D2 is 36 inches. That is the case.

[0074] The reading range of RFID reader 108 is zero distance from RFID reader 108. Please understand that it starts from here. RFID located right next to RFID reader 108 The tag can be read by the RFID reader 108 in order to respond to questions at that distance. Yes. It depends on the difference in packaging density, that is, the number of items in the package and the material of the items. Potential interference, and how the instrument or package is held by the HCP. This all affects the quality of the response signal and therefore the reliability of the reading. These are all possible factors. However, placing surgical instruments right next to an RFID reader is risky. This could compromise the sterility of surgical instruments. Therefore, maintaining the sterility of the product is important. To achieve this, establish a preferred reading range that is sufficiently far from the RFID reader. Preferably, but not so far away that it would simply elicit a response from surgical instruments stored nearby. stomach.

[0075] These measurements are illustrative and not intended to be limiting. To maintain the sterility of surgical instruments and minimize the impact on other environmental conditions, the first And other distances are intended for the second distance. For example, the storage of sponges The storage is located at a distance D3 which is longer than the maximum priority reading distance D2, and therefore the aggregation process It is intended that the RFID reader 108 inside the device is outside its effective reading range.

[0076] Sponge type (e.g., indicated by the dimensions of a rectangle and the number of pieces, if applicable), single The number of applicable types of sponges in the package, and the number of RFID readers 108 The following is an illustrative table of relevant power level parameters corresponding to the effective power output in the tenor. vinegar.

[0077] [Table 1]

[0078] As detailed in the table, the range of power levels associated with different packages is 10d The range is from Bm to 25 dBm. Power unit dBm (or dB m (represented as w) It is used to indicate the power ratio expressed in decibels (dB) relative to 1 milliwatt (mW). This is the unit of level used. The range of package quantity is one unit within a single package. The quantity may range from pongee to 10 sponges, but other quantities are also contemplated within the scope of this disclosure. Assuming all other things are constant, the more sponge there is in the package, the more related The associated power level parameters for sponge-type devices are higher. In the package, the power level parameter is lower. The size of the sponge inside the package is In addition to considering the number of sponges in the package, the power level of the package is affected. It can be given. For example, the table above shows how many units are available per package. However, these sponges, which have a lot of material and are therefore large in size, usually have a low power level. In this way, system 100 effectively manages the inventory of surgical instruments during surgical procedures. This ensures proper management and avoids careless tallying of surgical instruments stored nearby.

[0079] The table above shows the primary dimensions of the sponge in the package and the corresponding dimensions within a single package. It should also be noted that illustrative examples of package types based on the quantity of sponges are provided. This table is not intended to limit you to other sizes, other quantities, or other types. The surgical instruments of the same type are similarly intended by this disclosure.

[0080] The power level associated with a particular package type can be determined empirically. Example For example, to determine the power level of a specific package type and quantity, the type and quantity An example of a package is used with an experimental factor design to examine various environmental conditions (i.e., scanner) (When the number and location of appliances stored relatively close together differ) and running at various power levels It can perform evaluations. It can evaluate result sets across various conditions and successfully read the contents of the package. The signal to read all instruments in the package while minimizing the impact of ambient noise. The result set with the highest reliability can be evaluated. Other methods for determining the preferred power level are also available. It is further intended that they may be hired.

[0081] In relation to managing the inventory of surgical instruments, system 100 sets the inventory status of surgical instruments to H Includes a display 102 for communicating with the CP. Specifically, system 100 aggregates The type and quantity of surgical instruments used, and when the instruments were removed from the surgical procedure. Information identifying the quantity of surgical instruments that were later excluded from the count can be displayed.

[0082] System 100 also includes an RFID reader with a power level parameter corresponding to its device type. When configured to operate with a meter, more than the total quantity of sponges in the package The HCP will be alerted to the determination of an error condition, such as when a small quantity appears in the result set. It can be configured as follows. System 100 is the type of sponge presented, and the existing ones This includes the aggregated number, the expected number within the package, and the identification of discrepancies between the two. Error information can be displayed on display 102. System 100, Alternatively, or even better, this alert display could include an audible alarm, a visual alert such as a flashing light, etc. System 100 can also, for example, have leader 108 or base 106 If undocked, the mobile RFID reader 108 will activate a tactile response. This is possible. The tactile response may include vibration pulses or patterns of pulses.

[0083] Alternatively, the bundle 30 may include a master tag 32 containing unique identification information. For example. The master tag 32 includes the number of surgical sponges 10 contained in bundle 30, and bundle 3 The master tag 32 may contain unique identification information for each sponge 10 included in 0. In addition to the unique identification number of the sponge inside, the package It may contain a unique identification number.

[0084] The master tag 32 is to be scanned based on the location of the RFID tags 20 in the bundle 30 or It may be configured to identify the sides of the package / object. For example, the master tag 32 or Package 38 includes an arrow pointing to the side of bundle 30 that should be scanned for optimal accuracy, It may include an indicator 40 to facilitate such placement / orientation. Alternatively, The indicator 40 can be placed on the side of the bundle that should be positioned closest to the scanner. The indicator 40 can be placed on one or more sides of the bundle of sponges 30. The indicator 40 can be placed on any side / face of the bundle.

[0085] It is configured to hold individual sponges, multiple sponges, bundles of 30, or multiple bundles of 30. The container 50 is equipped with a similar master tag 52 configured to identify the contents of the container 50. It may include. For example, the container master tag 52 may include the number or bundle of sponges contained in container 50. The contents of container 50, such as the number 30, and any additional equipment or medical devices included in container 50. It can identify. The container 50 configured to hold a bundle of surgical sponges 30 is indicated As described above, the Cater 40 is configured to identify the optimal scanning direction / position / movement. It may be equipped with similar indicators. Master tags 32, 52 are bundled 30 or container 5 Information provided in relation to 0, which is human-readable or machine-readable, such as RFID tags. It can provide barcodes, QR codes (registered trademarks), etc. The master tags 32, 52 provide the same additional information or the same information as provided by device tags such as the FID tag 20. The master tags 32, 52 are useful for performing additional verification before using the device in a surgical procedure.

[0086] A first method 400 for managing the inventory of surgical instruments used during a surgical procedure is illustrated. The surgical instrument can be, as described above, the surgical sponge 10. Implementing the described method 4 00 helps ensure that the HCP properly removes the surgical instrument after the surgical procedure. This method includes a first step 402 of providing an inventory of surgical instruments such as surgical sponges. The inventory can be stored in a container such as the mobile cabinet 112 illustrated in FIG. 2. The inventory includes packages of surgical instruments. In a first example the inventory includes at least a first package containing at least a first surgical sponge of a first sponge type. The first surgical sponge includes a first unique identifier associated with the sponge, first package content information, and a first power level parameter associated with the first sponge type, stored in a first RFID tag. The first package content information corresponds to the complete contents of the first package. The use of the designations "first" or "second" is only to refer to individual iterations of the aggregation method steps and is not intended to limit or require that "first" be different from "second" unless specifically stated. [[ID=,29]] [[ID=]]

[0087] As described above, the package can contain 2, 3, 5, 10, 20 or more items within a single package. It may include multiple devices, such as quantity. The unique identifier is an identification key stored in the RFID tag. It can be a single memory data field or a combination of entries from multiple data fields. Together, they can form a single unique identifier. Package contents information includes a unique package and includes such information necessary to identify the contents of the package (such as quantity). For example, the package contents information is a unique package ID 126 of the identification scheme 120. In relation to this, sponge type ID 124 and specific Sponge number 128 identifies the position of the sponge within the package in the total quantity. It can include...

[0088] This method is the second step in operating the RFID reader at the default power level. Includes 404. The step of operating the RFID reader is within the range of the RFID reader. This refers to initiating the release of radio energy to elicit a response from an RFID tag. To initiate the steps, the HCP will either directly or through other connected hardware components. This can provide input to the RFID reader. The default power level is not necessarily specific to This shows the power level setting of the reader, which is not related to the Pongee type. For example, the default The power level may represent the intermediate range of the RFID reader's operating capability. Alternatively, the default The power level of the sponge is adapted to various sponges so that the RFID reader can read it. This can represent the intermediate range of power level parameters related to the type. For example, the default power The power level parameter can be set to 15 dBm. In other alternatives, the default power level parameter is... The force level depends on the specific environment in which the RFID reader operates, or on other considerations mentioned above. This allows you to select one of the maximum or minimum extreme values ​​of the RFID reader's range. .

[0089] This method allows the RFID reader to operate at the default power level. This includes step 406, which receives one or more responses to the action. The TEP is a system where HCP attaches RFID tags to the packaging of surgical instruments and connects them to an RFID reader. To present something physically, or conversely, for an RFID reader to be able to read an RFID reader effectively. This includes positioning the package so that it fits within the reading range. The preferred reading range is The length can be between 12 and 36 inches. The response to step 404 may be one or more. It can contain a number of tag data. For example, in an environment where multiple RFID tags exist, RFID The reader uses an anti-collision function or reads data from multiple tags in a single read operation. It can read, collect, and process data. For example, such an anti-collision machine. The performance conforms to the industry standard ISO / IEC 15693-3:2009 - Anti-collision and transmission This is described in the transmission protocol. The RFID reader is used to perform the operation of this method. It communicates with a computer processing device or incorporates a computer processing device. The information is stored in the RFID reader's memory and the memory of another computer processing device. It can be stored in a database or distributed across multiple computer processing devices. The description of any processing or calculation step is an RFID reader, or an RFID reader This can be done by another device that is communicating with it.

[0090] Of the received response data, the data of the first tag continues the steps of method 400. is used, and the data of the first tag includes the first unique identifier, the first power level parameter stored in the first RFID tag, and the first package content information of the first tag. The data for continuing method 400 from this step 406 can be the first complete data received within the response time. Alternatively, the response in step 406 can prioritize the use of a certain type of sponge over other types of sponges or use other criteria to specify or select a particular sponge to proceed with the steps of method 400 in sequence. In one example, the response data received at the default power level can be evaluated to determine whether multiple sponges from a single package are present in the response set. If the sponges with the minimum ratio from a single package are present in the response data, the first tag for continuing the steps of method 400 is selected from the packages with at least the minimum ratio present. The minimum ratio can be between about 25% and about 50% of the sponges within the complete package. The minimum ratio can be at least 30% of the sponges in the complete package. including the first power level parameter stored in the first RFID tag, and the first package content information of the first tag. The data for continuing method 400 from this step 406 can be the first complete data received within the response time. Alternatively, the response in step 406 can prioritize the use of a certain type of sponge over other types of sponges or use other criteria to specify or select a particular sponge to proceed with the steps of method 400 in sequence. In one example, the response data received at the default power level can be evaluated to determine whether multiple sponges from a single package are present in the response set. If the sponges with the minimum ratio from a single package are present in the response data, the first tag for continuing the steps of method 400 is selected from the packages with at least the minimum ratio present. The minimum ratio can be between about 25% and about 50% of the sponges within the complete package. The minimum ratio can be at least 30% of the sponges in the complete package. Based on the first RFID tag data, method 400 includes step 408 of reconfiguring the RFID reader to operate according to the first power level parameter corresponding to the first sponge type, and step 410 of operating the RFID reader at the first power level. This operation constitutes a second interrogation by the RFID reader, but at a power level different from the default power level. The first power level can be higher or lower than the default power level, thereby resulting in more or fewer highly responsive tags.

[0091] Based on the first RFID tag data, method 400 includes step 408 of reconfiguring the RFID reader to operate according to the first power level parameter corresponding to the first sponge type, and step 410 of operating the RFID reader at the first power level. This operation constitutes a second interrogation by the RFID reader, but at a power level different from the default power level. The first power level can be higher or lower than the default power level, thereby resulting in more or fewer highly responsive tags. This operation constitutes a second interrogation by the RFID reader, but at a power level different from the default power level. The first power level can be higher or lower than the default power level, thereby resulting in more or fewer highly responsive tags. This operation constitutes a second interrogation by the RFID reader, but at a power level different from the default power level. The first power level can be higher or lower than the default power level, thereby resulting in more or fewer highly responsive tags. This is the answer. If the first power level is higher than the default power level, for example, In the case of sponge types where multiple sponges are packed more densely into one package, the stronger Powerful questions can be more effective by overcoming interference caused by the proximity of multiple tags. Tags with high response rates may be found. The first power level is lower than the default power level. In some cases, such as when a single sponge type is packaged in one package, effective Because the reading range is reduced to a closer range, the number of response tags decreases. Therefore, the method Step 400 includes receiving a first response set to a first power level.

[0092] During step 412, when the system receives a first set of responses at a first power level, It may be configured to selectively search for a single sponge type corresponding to a first sponge type. The response to the question at the first power level that does not match the first sponge type is the first It can be automatically excluded from the response set, reducing the amount of data processed.

[0093] Next, Method 400 determines the error condition by setting a power level different from the default power level. A first set of responses in response to the operation of the RFID reader at a first power level, and a first This includes step 414, which compares the package contents information with the first response set. The uniqueness of all tags within the effective reading range of the RFID reader at this power level. It has identification information. The RFID reader operates at the default level, and the first package Based on the response to step 404, which receives content information, a first response set (RFID A comparison can be made with the response when the commander is operated at a first power level.

[0094] When the package is complete, i.e., error-free, the first response set is , appropriately including the identification numbers of all sponges indicated by the first package contents information It is likely that the first package contents information is information about multiple sponges within a single package. In this case, this involves managing the use of surgical instruments during surgical procedures and the use of hands within the patient after surgical procedures. Minimizing HCP errors or confusion when avoiding undesirable inclusion of surgical instruments. To achieve this, it is crucial to verify that all expected equipment actually exists. In total, the complete package of surgical instruments is assembled for the surgical procedure in step 416, and the instruments are In surgical procedures, it can be placed in an appropriate staging area at the HCP's discretion. The above steps begin with step 404, which powers the RFID reader with the power of the folt. Branch 4 will be used until the desired stock of surgical instruments is compiled and available for surgical procedures. This can be repeated along step 17. When the RFID performs the steps described, the package Different types of sponges with varying quantities and associated power levels may coexist. The different power levels associated with the package type are, regardless of the sponge type, R The distance between the FID reader and the surgical sponge package is approximately 12 inches to 36 inches. Maintain a preferred reading range.

[0095] Comparing the first set of responses with the first package contents information indicates that the package is complete. This may indicate that it is not a package. If this decision is made in step 418, HCP will show an error. —A warning may be issued regarding this. This step can be carried out in various ways. For example, RFID Visual alerts can be displayed to the HCP on a display that communicates with the reader. The visual alert displays the type of sponge presented, the number and ID of the responding tags, and the packaging. Specific information about the error, such as the expected number in the cage and the identification of discrepancies between the two, is displayed in the table. It may be shown. Alternatively, or further, HCP may be a display or RFID reader. Error decisions may be warned by other visual alerts, such as a light that stays on or flashes. HCP, for example, in an RFID reader, detects errors with an audible alarm or tactile response. A warning may be issued. The tactile response may include vibrational pulses or patterns of pulses.

[0096] When an error condition is warned, HCP will try to correct the error if possible, or Alternatively, the incomplete packaging of the sponge will be discarded and transferred to other packaging provided to the inventory. Proceed along branch 419 and operate the RFID scanner at the default power level. It starts with compiling the inventory of desired surgical instruments so that they can be used for surgical procedures. You can repeat the 400 steps of the method until you reach your goal.

[0097] Once the desired stock of surgical instruments is compiled, the HCP proceeds with the surgical procedure as step 420. This can be done. Once the surgical procedure is complete, the surgical instruments can be used to treat the patient in step 422. Then it is removed. Following removal from the patient, for example in step 424, the RFID reader By using the scanner to read the surgical instruments again, the surgical instruments are excluded from the count. Therefore, excluding surgical instruments from the count is because the labels provided to the surgical instruments are optically run. To review or to manually enter information to exclude surgical instruments from the calculations. It may include the following.

[0098] During the exclusion step 424, the RFID reader operates at the default power level. It is possible. Alternatively, the RFID reader can be aggregated for processing, and still excluded from aggregation. It can operate at power levels corresponding to the power level parameters of a non-sponge-type device. The sponge types are aggregated, and the sponge types have different associated power level parameters. In this case, the RFID reader operates at different power levels associated with different sponge types. It can operate by sequentially executing question actions while cycling through them. RFI The D-leader receives the response set and is not related to the power level of a particular question cycle. While excluding responses from other types of sponges, it addresses the power level of a specific question cycle. Only responses from this type of sponge can be registered.

[0099] Method 400 also includes step 426 of displaying the status of the surgical instrument inventory. Figure 4 shows the diagram. As illustrated at the end of the method, this step is consistently applied throughout the entire method. It is intended that the RFID reader may respond to question steps 406 and 412. The type of sponge is indicated, and as the surgical procedure progresses, the aggregated and excluded externals are shown. Maintain current statistics of medical instruments. For example, displaying the status of instrument inventory is necessary. Display specific summaries for surgical instruments, including those excluded from the summaries, for each type of surgical instrument. This may include: This indication of stock status refers to the immediate availability of surgical instruments for surgical procedures. It provides immediate and instant calculations, reducing the burden on HCPs when tracking and summarizing the use of surgical instruments. To minimize the risk and ensure that no surgical instruments are left behind in the patient after the surgical procedure.

[0100] A second method 500 for managing the inventory of surgical instruments used during surgical procedures is illustrated in Figure 5. The surgical instrument may be a surgical sponge 10, as described above. Implementing Method 500 ensures that the HCP can properly remove surgical instruments after a surgical procedure. Helps to ensure any particular method and system described herein. The symbols / steps can be used in conjunction with other methods and systems described throughout. I hope you understand this.

[0101] Method 500 is the first step 50 of providing a stock of surgical instruments such as surgical sponges. Includes item 2. The inventory is stored in containers such as the mobile cabinet 112 shown in Figure 2. This is possible. The inventory includes packages of surgical instruments. In the first example, the inventory is , at least a first pad including at least a first sponge-type surgical sponge Includes cage. The first surgical sponge is a first unique identifier associated with the sponge, the first Package contents information, and the first power level parameter related to the first sponge type. Includes a first RFID tag that stores data. The first package contents information is stored in the first package. This corresponds to the complete content of the page. The use of the designation "1st" or "2nd" is for aggregation purposes. It simply refers to individual iterations of the legal steps, and unless otherwise specified, “the first” is This is not intended to restrict or require anything different from "Second."

[0102] As described above, a package can contain 2, 3, 5, 10, 20 or more numbers within a single package. It may include multiple devices, such as quantity. The unique identifier is an identification key stored in the RFID tag. It can be a single memory data field or a combination of entries from multiple data fields. Together, they can form a single unique identifier. Package contents information includes a unique package This includes information necessary to identify the contents of the package (such as quantity). The package contents information is associated with a unique package ID 126 of the identification scheme 120. Sponge type ID 124 to obtain the complete package quantity, and the specific sponge Includes sponge number 128 which identifies the position within the package in the complete quantity. It is possible.

[0103] Method 500 involves step 504 to operate the RFID reader and the RFID reader This includes step 506, which receives tag information in response to being activated. To get started, HCP uses RFID directly or via other connected hardware components. This step allows the reader to receive input. To specifically present the package to the RFID reader, or conversely, to the RFID reader Position the package so that the reader is within the effective reading range of the RFID reader. This includes the following. The preferred reading range may be between 12 and 36 inches. A response to a 504 error may include one or more tag data. For example, multiple RFIs. In environments where D tags are present, the RFID reader will use the anti-collision function, or 1 A single read operation can read, collect, and process data from multiple tags. Example For example, such anti-collision functionality conforms to the industry standard ISO / IEC 15693-3: Described in 2009-Anti-collision and transmission protocols. RFID reader To perform the operation of this method, it communicates with a computer processing device or the computer It incorporates a computer processing device. The information is processed by an RFID reader and another computer. It is stored in a database stored in the memory of the computer device, or across multiple computers. Processing can be distributed across processing devices. Description of any processing or computation step is provided by the RFID reader. —or it can be done by another device communicating with the RFID reader.

[0104] Of the received response data, the data of the first tag continues to step 500. Used for this purpose, the data of the first tag is sufficient to identify the sponge type. Includes identifiers and information of the type. Information identifying the sponge type includes specific sponge types. This includes or can be used to obtain the relevant RSSI aggregation threshold. The data for continuing from step 506 to method 500 is the first data received within the response time. It could be complete data. Alternatively, the response in step 506 is a type of sponge. Prioritize the use of this type of sponge over other types of sponges, or use other criteria to determine the specific sponge You can specify or select a step to proceed through the steps of Method 500 in order.

[0105] Based on the first RFID tag data, method 500 determines the RS of the first RFID tag response. Step 508 determines the SI, and the determined RSSI is associated with the sponge type. The RFID reader includes step 510, which compares the tag information with the RSSI threshold. Determine the RSSI of the first RFID tag response, or process the first RFID tag response to R To determine the SSI, another computing device such as a system computer The RSSI can communicate information related to the first RFID tag response. The RSSI is a question that prompts a response. It is determined as the measured power of the response signal to the power of the number.

[0106] The RSSI determined for a specific tag is equal to or greater than the RSSI threshold associated with sponge type. If so, the relevant sponge is to be used with it in step 512. It is tallied in place. If the relevant RSSI threshold for the relevant surgical instrument type is not met, A tag response that does not exceed the limit is intended not to mean an error that requires HCP to be warned about. Rather, a low RSSI is, for example, when stored nearby but in a surgical procedure. This could simply mean a tag response as ambient noise from surgical instruments not intended for use. Step 504, which operates the reader, as shown along branch 513, tag information Step 506 to receive the information, step 508 to determine the RSSI value, and step 506 to compare P510 will continue until the desired stock of surgical instruments is checked in for the surgical procedure. It repeats.

[0107] Method 500 includes step 520 of displaying the status of equipment inventory. The method is illustrated in Figure 5. As illustrated at the end, this step is performed continuously throughout the entire method. The intention is to indicate the type of sponge that responds to the RFID reader's question step 506. And, as the surgical procedure progresses, the current total of surgical instruments that have been tallied and excluded from the total. Maintain this. For example, displaying the status of instrument inventory means that the types of surgical instruments present are... This may include displaying specific aggregates of surgical instruments that have been aggregated and excluded from the aggregate. This inventory status display provides a direct and immediate calculation of the surgical instruments present for surgical procedures. This minimizes the burden on HCPs when tracking and compiling the use of surgical instruments. Ensure that no surgical instruments are left behind in the patient after the procedure.

[0108] A specific package of surgical instruments is presented by the HCP for aggregation purposes, for example, Update the display steps and add package quantity and type as aggregated, etc. If approval is not granted by the system, the HCP will bring the package closer to the RFID reader. Alternatively, by placing the package in the center in front of the reader, the RFID reader can be positioned correctly. The HCP may attempt to adjust the package's position. Adjust the orientation relative to the reader, or move and rotate the package relative to the RFID reader. By combining these, it may be possible to attempt to aggregate the packages. In some cases, it may be determined by a specific instrument. The defined RSSI may not reach the threshold RSSI associated with the device type. In this case, HCP can discard the equipment as defective. Sufficiently strong in the aggregation phase. If a response signal cannot be achieved, it means the device is unable to provide a response signal during the aggregation exclusion phase. This indicates the confusion for HCPs who try to manage and calculate instrument inventory at the end of surgical procedures. There's a possibility of connection.

[0109] Once the desired stock of surgical instruments is compiled, the HCP will proceed with the surgical procedure as step 514. This can be done. Once the surgical procedure is complete, step 516 will show the surgical instruments to the patient. Then it is removed. Following removal from the patient, for example in step 518, the RFID reader By using the scanner to read the surgical instruments again, the surgical instruments are excluded from the count. Therefore, excluding surgical instruments from the count is because the labels provided to the surgical instruments are optically run. To review or to manually enter information to exclude surgical instruments from the calculations. It may include the following.

[0110] During the exclusion step 518, a response to the question signal is received, and the sponge is previously used for treatment. When aggregated, the RFID reader operates at the default power level and sponsor The data can be excluded from the count. Alternatively, the RFID reader can exclude the data that has been counted for processing. According to the power level parameters associated with the Pongee type, the power level of the consecutive question cycles It can be operated by changing the bell. In a further alternative, the RFID reader is Step 424 describes the variable power level method used to evaluate the RSSI of a specific sponge and By combining these, you can verify that the appropriate sponges are excluded from the calculation. (Exclusion process) To achieve the required RSSI during the process, the sponge is presented within the range of the RFID reader. This allows for the sponge remaining in the surgical field to be inadvertently excluded from the count.

[0111] In line with the above description, Method 500 is, for example, a calculation and calculation subtraction through surgical procedures. To display the status of the equipment inventory 520, including providing the identification number of the removed equipment. include.

[0112] Further methods for managing the inventory of surgical sponges used during surgical procedures are shown in Figure 6. As illustrated above, the surgical instruments are as shown in the diagram. Similar to methods 400 and 500 above, the surgical instruments are as shown above. This could be a surgical sponge 10, and this method ensures proper removal of the surgical sponge after the surgical procedure. This can be helpful in supporting HCP when ensuring safety. In this case as well, the above method 400, Like method 500, method 600 provides a stock of surgical instruments such as surgical sponges. This includes step 602. The inventory is stored in a mobile cabinet 112, as illustrated in Figure 2. It can be stored in a container. The inventory includes the packaging for surgical instruments. The first In the example, the inventory includes at least one first surgical sponge of the first sponge type. Both include the first package. The first surgical sponge is the first unique related to the sponge. The identifier, the first package contents information, and the first electricity related to the first sponge type Includes a first RFID tag that stores force level parameters. The first package contents information , corresponds to the complete contents of the first package. The designation "First" or "Second" Usage refers only to individual iterations of the aggregation method step, unless otherwise specified. This is not intended to limit or require that "the first" be different from "the second". .

[0113] As described above, a package can contain 2, 3, 5, 10, 20 or more numbers within a single package. It may include multiple devices, such as quantity. The unique identifier is an identification key stored in the RFID tag. It can be a single memory data field or a combination of entries from multiple data fields. Together, they can form a single unique identifier. Package contents information includes a unique package This includes information necessary to identify the contents of the package (such as quantity). The package contents information is associated with a unique package ID 126 of the identification scheme 120. Sponge type ID 124 to obtain the complete package quantity, and the specific sponge It may include sponge number 128, which identifies the position within the package in the complete quantity. .

[0114] Method 600 involves step 604 to operate the RFID reader and the RFID reader 6 The step includes receiving tag information in response to operating 04. RFID Step 604, which activates the reader, is to bring the RFID reader to the initial power level for the first period. This includes operating during this step 604. During this step 604, the RFID reader is limited to the first During the specified period, a first set of responses is collected. Based on the initial power level, the first set of responses is collected. The package is evaluated, and it is determined whether a complete first package exists in the response set. In other words, based on the collected tag responses and the package content information of the tag responses, complete All equipment in the package operates at initial power levels during the first period of RFID It is determined whether it exists in the response set as a response to the message. Complete package If it is determined that the `Ji` is present in the response set, method 600 optionally performs a complete package. The cage is associated with the initial power level of the RFID reader in step 604. The procedure includes a step of evaluating whether it is of a type that has a certain power level.

[0115] A complete package exists, and the complete package matches the initial power level of the associated electricity Once it is determined that it is a type with a force level, the instrument in the complete package is in step 6 It is counted as a surgical procedure at 10. The complete package is found, but the instruments are early electric It may not be the type that has a corresponding power level that matches the force level, In that case, the instrument will not be counted as a surgical procedure.

[0116] The devices are tallied after the first operation of the RFID reader at the initial power level of the first period. Then, in step 612, the RFID reader increases (incrementally) the power level, which is different from the initial power level. It can be reconfigured to operate at (incremental) power levels. This method is Start with a low-power RFID reader and increase to a high-power level, or high-power It is possible to start with a high-power RFID and increase to a lower power level. At Bell, background tag responses from nearby stored devices are detected by the RFID reader. - The likelihood of reception increases. At lower power levels, the tags are closer to each other. This can cause interference or attenuation of the RFID reader's interrogation signal, resulting in densely packed packages. There may be fewer tag responses received from sizing surgical instruments. Therefore, The power level range circulates within the operating capability of the RFID reader, and the RFID tagged device It is beneficial to ensure that the appropriate set is reliably included in the surgical procedure statistics.

[0117] With increased power levels, reception of response sets, and package aggregation, the RFID reader The steps to be performed are determined to be complete and match the power level of the cyclic operation. If it is a type with the relevant power level, the desired RFID tagged equipment stock will be processed It can continue along branch 613 until it is tallied for use. The desired stock of surgical instruments If it is categorized as a surgical procedure, HCP can proceed with the surgical procedure as step 614. Yes, it is possible. Once the surgical procedure is complete, the surgical instruments are removed from the patient in step 616. Following removal from the patient, for example in step 618, an RFID reader is used By scanning the surgical instruments again, the surgical instruments are excluded from the count. (Exclusion step) In the P618, the RFID reader can operate at the default power level. Alternatively, the exclusion step 618 may be the same as the exclusion step 424 described above. It may be the same as both of step 518. Alternatively, surgical instruments may be excluded from the count. This involves optically scanning the labels provided on surgical instruments, or collecting and removing the labels from surgical instruments. This may include manually entering information to specify it as an external item. In accordance with the above description, Method 600, for example, uses the identification numbers of instruments that have been tallied and excluded from the tally through surgical procedures. This includes providing and displaying the status of equipment inventory.

[0118] In one embodiment, step 402 provides a stock of sponges such as stock 112. RF readers such as FID reader 108 are provided, as well as touchscreen 104. By inputting into the RFID reader 108, it switches to operating in aggregation mode. The RFID reader 108 can be connected to the system computer 101 or the RFID reader. It initially operates with the default power level value of 15dBm, which is stored in one of the -108 values. It is configured in such a way. The RFID reader 108 performs the questioning cycle in step 404, etc. The first response to the question was taken from a portion of the inventory presented to the RFID reader for aggregation. The system receives the set. System 100 is connected to system computer 101 or RFID reader. In any of the steps in step 108, for example in step 406, a single package contains a sponge Evaluate the first set of responses to identify at least 30% of the RFID reader. -108 consists of two 18" x 18" wrap sponges, each with the same unique package ID 12 It is determined that it exists in the first response set which has 6.

[0119] RFID reader 108, for example, in step 408, 18" x 18" wrapped sponge Reconfigure to operate at 14 dBm, which is the power level parameter associated with the type. The power level parameter is set to the system computer 101 or the RFID reader 108. Retrieved from a stored lookup table or database. RFID reader 108, for example, in step 410, performs the question cycle at 14 dBm. RFID Orderer 108 receives a second response set, for example in step 412. The set contains five 18" x 126 boxes, each bearing the same unique pack ID 126, representing the complete package. The response data is from an 18" wrap sponge. Optionally, the system is 1 It is possible to exclude data from a second response set that does not correspond to the 8" x 18" wrap sponge type. System 100 determines the complete package, for example in step 414, and for example in step We've compiled a list of 5 18" x 18" plastic wrap sponges for use in surgical procedures at pp416. The RFID reader 108 is reconfigured to operate at the default power level. For example, in step 417, until all the necessary equipment is totaled, the remaining stock of 112 Continue checking inventory for the portion. RFID reader 108 follows the same sequence. At the default power level, of the 10 2"x2" gauge sponges in the package Detect at least three of these, reconfigure to operate at 25dBm, and power level 25dBm The bell detects all 10 of the 10 sponges in the package, and then the 10 2"x2" sponges The packages of gauze sponges are tallied. When the remaining stock of 112 is tallied, for example, At step 420, the surgery is performed using the collected instruments.

[0120] After the surgical procedure is completed, the collected instruments are excluded from the count, and as a result, step 424 After procedures such as those mentioned above, no device will be unintentionally left inside the patient. RFID reader -108 provides input to the touchscreen 104 or RFID reader 108. This allows it to be switched to operate in exclusion mode. RFID reader 108 The collected 18" x 18" wrap sponges and 2" x 2" gauze sponges While searching for each, continuous questioning was conducted at 14 dBm and 25 dBm at 300 millisecond intervals. Run the crunch. The consecutive questions continue until all sponges of one type are excluded from the tally. To be continued. Subsequently, the continuous question cycle is related to the power level associated with the aggregated sponge type. This occurs only in the case of .Optionally, system 100 selects each spot identified in the response set. Evaluate the RSSI related to the range and find the minimum response intensity before the sponge is excluded from the aggregation. It can be confirmed that it exists.
