A physician is not required to manually map each electrode with its corresponding input channel. Electrodes are coupled to their corresponding input channels in groups through connectors having a unique identification (ID). A system reads the unique ID of each connector and establishes its identity. Based on the ID, the system configures itself to correlate or associate each electrode with its corresponding input channel when the connectors are first inserted into the receiving sockets, and again, if the connectors are removed and re-inserted into different positions in the receiving sockets, to insure the electrodes are always mapped to the same input channels.SELECTED DRAWING: Figure 2

[Technical field]

[0001] cross reference The present invention relates to "System and Method for High Density This application is based on U.S. patent application Ser. No. 15 / 376,655 entitled "Ty Electrode Management" No. 6,313,635, filed on Oct. 13, 2006, the contents of which are incorporated herein by reference.

[0002] The present invention relates to the field of neuromonitoring applications, and more particularly to the various The present invention relates to a system and method for managing a number of electrodes. [Background technology]

[0003] Some medical procedures use on-body sensors to record and monitor data necessary for patient care. It requires the placement of multiple sensors to measure vital health parameters, cardiac activity, biochemistry, and other parameters. Information on brain activity, electrical activity in the brain, gastric activity, and physiological activity is usually collected by on-body sensors or Recording is performed using body-embedded sensors / electrodes, which may be connected to wired or wireless devices. A typical patient monitoring system is controlled through a link. A control unit is connected via wires to one or more of the associated electrodes. For applications using pulse oximeters or EKG devices, the device may be attached to the body. The number of electrodes to be used is not so large (a small number of electrodes), so they can be easily managed. However, in applications where a large number of electrodes need to be coupled to the body, the overall electrode setup , deployment and management becomes a tedious process.

[0004] Neuromonitoring is the monitoring of the function of selected neural structures (e.g., nerves, spinal cord, and brain regions) during surgery. Electrophysiology, such as electroencephalography (EEG) and electromyography (EMG), to monitor functional integrity The purpose of neuromonitoring is to assess the patient's risk of iatrogenic injury to the nervous system. In general, the aim is to reduce Neuromonitoring procedures such as EEG require multiple electrodes coupled to the body. In treatment, multiple electrodes are used to detect and treat various illnesses such as epilepsy, sleep disorders, and coma. It is used to record and monitor electrical activity corresponding to different parts of the brain for therapeutic purposes. EEG procedures can be either non-invasive or invasive. In non-invasive EEG, multiple electrodes are used. are placed on the scalp to record the electrical activity of the parts of the brain beneath them. In this type of surgery, electrodes are placed in strips or grids over parts of the brain, or Each of these electrodes is connected to a lead that transmits electrical current. The electrodes are connected to a control unit configured to receive and transmit signals. The electrical activity patterns obtained can be used to localize or find areas of the brain that are responsible for specific diseases. The data is then parsed using standard algorithms to determine the

[0005] The number of electrodes in an EEG system typically varies between 21 and 256. More electrodes help reduce localization errors, allowing doctors to perform better surgery. Therefore, modern EEG systems are able to measure all parts of the brain. A high-density electrode array of up to 256 electrodes was used to map the electrical activity of the However, as the number of electrodes increases in EEG procedures, the overall sensitivity The setup and validation process is time consuming and error prone.

[0006] In neural monitoring, each electrode has a different Since the electrodes are placed at different positions, the input recorded from each electrode must be processed independently. The system recognizes the identity of each electrode and processes the input received from that electrode accordingly. To achieve this, it is required to place each electrode in the neuromonitoring system. It is important to couple to the correct input channel of the control unit. In this case, the caregiver connects one electrode to each of the input channels while multiple electrodes are connected to each of the input channels. It is possible to connect to the wrong input channel, which can cause the whole process to fail. Therefore, in high-density electrode configuration, the corresponding connection to each electrode must be established individually before treatment can begin. The setup process is time consuming because the integrity must be verified before The time it takes to set up and verify multiple lead connections is reduced by having them all done before treatment begins. This prevents best practice in testing electrodes and subsequently verifying their integrity, thus compromising the quality of medical care. This means that...

[0007] Surgical applications of EEG also use grid electrodes. Grid electrodes are essentially multi-lead electrodes. (up to 16) into a single connector, which is then split into 16 individual links. The inputs are then attached to an adapter with a corresponding input for each channel. However, the patient is connected to an EEG system with 200+ electrodes. When monitoring with a , grouping these electrodes together would result in more than a dozen adapters, The connections corresponding to these adapters must be verified individually every time before starting treatment.

[0008] Therefore, current neuromonitoring medical devices that contain multiple electrodes are difficult to place these systems on. These systems do not provide physicians with an easy and convenient way to check the Misplacement of these systems poses serious risks of inaccurate measurements. Moreover, the deployment of these systems requires a great deal of time, and subsequent optimization is required. This would hinder implementation and reduce the quality of medical care.

[0009] What is needed is a device and system that is easy to use and does not require a lot of time to configure. Such devices and systems automatically recognize the location or identity of the various electrodes. , associate those electrodes with specific input channels, allowing the physician to assign each electrode to a specific input channel. There should be no need to manually map with force channels. Summary of the Invention

[0041] The systems, devices and methods described below are directed to neuromonitoring, such as electroencephalography (EEG) procedures. A novel electrode management solution for electrode management in such applications is disclosed. A system and method are disclosed that provide a highly reliable and convenient method of In the system embodiment, the physician connects each electrode lead to a corresponding input channel on the system control unit. This eliminates the need for manual matching of the The electrodes are connected directly to the control unit of the neuromonitoring system or to the input channels of the amplifier. Rather, the control unit is connected to the electrodes with the aid of a unique connector and a corresponding socket. When combined, the socket contains the electrode type and placement location and can automatically detect the electrode. Once the electrodes are identified, the control unit instructs the system to map each electrode to a corresponding automatically correlate, associate, assign, or "map" the input channels Here, we will redefine the terms "correlate," "associate," "assign," and "associate." Or "mapping" means to map a particular electrode to a corresponding particular input channel in the control unit. The connector and receptacle are the components that allow the control unit to place the The electrodes are correctly identified, and the information received from each electrode is recorded in the connector, so that it can be inserted into the receiving socket. Ensures proper processing of electrode placement on the patient's body, regardless of whether do.

[0042] In some embodiments, the electrodes are configured to have similar monitoring functionality and similar locations on the body. Multiple groups were created so that electrodes of similar types based on placement location were included in the same group. For the purposes of this specification, "similar monitoring functionality" refers to "electrodes" refers to electrodes used in similar neuromonitoring modalities, including but not limited to: Electrodes used in research such as electroencephalography (EEG), electromyography (EMG), and evoked potential testing The devices are grouped into groups of similar monitoring functionality. Thus, all devices used for EEG All electrodes constitute electrodes with similar monitoring functionality and can be used in conjunction with other modalities such as EMG. are clearly distinct from electrodes used in diagnostics (which do not have similar monitoring functionality). For the purposes of this specification, "similar placement position" refers to the position of the patient's head or headrest. This refers to electrodes placed together at specific locations on the skin, e.g., the front, back, and back of the patient's scalp. Electrodes configured for placement on the left, right or right side of the head are similarly positioned based on each location. Thus, all electrodes placed on the patient's scalp at the front are grouped into Electrodes having similar placement positions are constructed and placed on the patient's scalp at the back, left or right side of the head. These electrodes are clearly distinct from the electrodes used (because they do not have similar placement locations) and Each of the electrodes has a different placement position.

[0043] The electrodes of each group are then mapped to separate connectors in a predefined order. All the connectors are mated with the sockets on the system control unit. When the poles are mapped to a connector, the poles are attached to the connector in a given order. The exact location and type of each electrode within the group is standardized and unique to the connector so that The connector and the receiving socket are assigned an identity code or ID. When any connector is inserted into a socket, the The socket can identify the connector from its unique identification code or ID, and the connector Based on the identity of the connector, all electrodes mapped to this connector are The specific location and type are determined. The ID information is explicitly carried by the connector and The ID information is implicitly carried by the electrically accessible In various embodiments, the memory may be, for example, a read-only memory (ROM). M), programmable read-only memory (PROM), erasable programmable read Electrically Erasable Programmable Read-Only Memory (EPROM) and Electrically Erasable Programmable Read-Only Memory (ERM) non-volatile memory such as EEPROM, or a combination of both, and Dynamic Random Access Memory (DRAM) and Static Random Access Memory (SRAM) The electrodes and connectors of the group are never separated. If the connector is reinserted elsewhere on the array of available inputs, the system The system remaps those inputs to the correct channels. The ID information is stored in all electrodes at once, in some embodiments, compared to one electrode at a time in current systems. 16 electrodes at a time. The information needed to determine where to attach the electrodes is (using a unique ID) and a given setup (e.g. 10 / 20 system headset (in the case of a cap) or specified by the user on a per connector basis to the computer system It is a function of the specified setup.

[0044] In some embodiments, when the connector is mated with the receiving socket, the medical system The user then selects the specific In one embodiment, the user provides information regarding the various electrodes that are coupled to the input. Enter this information manually via a keyboard or keypad associated with the system (or (select data from a list of available options). Once the user provides this information ,The exact location and type of electrodes within a group coupled to a particular connector is standardized. In some alternative embodiments, information regarding the exact order in which the electrodes are coupled to each connector may be provided. is provided to the medical system prior to insertion of the connector into the receiving socket.

[0045] The receiving socket has a bank of input points, each with a unique ID and representing a separate electrode group. The connector is configured so that any suitable connector can be inserted into any input on the receiving socket. When the socket establishes an electrical connection with the connector, the receiving socket reads the connector's unique ID. You can read the connector's identity and verify its identity. Upon validation, the system will determine the type and specific location of the various electrodes mapped to the connector. It can be recognized.

[0046] Using the concept of connectors with unique IDs as disclosed herein: The location of electrodes within a particular group is standardized to the connector. The poles are mated to the inputs of the connector in a predetermined order and the system reads the unique ID of the connector. The caregiver should assign the correct designation (electrode type and position) to each electrode. The electrodes corresponding to the single connectors are mapped in the same predetermined order or sequence prior to the procedure. Once identified, electrode groups can be removed and It can then be reinserted into any available slot without error. The system will Pay attention to the new connections and ensure the correct sense is given to the inputs. The handling of the electrodes is important in high-density electrode applications such as EEG procedures involving more than 200 electrodes. This makes the whole setup process less cumbersome. Conventional systems require Removing and reinserting a corresponding electrical connector into a receptacle located within the medical device. In this case, each electrical connector must be reinserted into the exact same receptacle or electrode body. However, in the above system, the user must remove various connectors from the medical device. These connectors can then be reinserted into any input point in the receiving socket.

[0047] An exemplary beneficial use of the connector system herein is in conjunction with an MRI procedure. The input of the monitoring system amplifier is itself generated by the MRI machine. It must be isolated from the amplifier itself, since it cannot be allowed to enter a strong magnetic field. Disconnecting and reconnecting 200 leads for such a procedure is time consuming and prone to error. This laborious process is the preferred imaging technique, with MRI procedures being the preferred imaging technique. Even if the lead is not identified, it may prevent the use of MRI procedures. In a network environment, the above process is not only error-prone, but also requires manually re-running each channel. Some systems require the channels to be used consecutively. Therefore, the "abandoned" channel will continue to be displayed. The improved connector system reduces the chance of misconnecting leads and , the above process will be faster.

[0048] Any feature or component described herein in the context of a specific embodiment may be can be used and practiced with any other embodiment unless expressly indicated otherwise. Please note that.

[0049] FIG. 1 illustrates a conventional medical system 100 that includes multiple electrodes placed on the body of a patient 102. The medical device 101 may be any conventional neuromonitoring device with multiple electrodes. The present invention relates to a medical system, such as an electroencephalography (EEG) system, which is capable of detecting a specific disease. To monitor the neurological status of patients for diagnosis and preventive treatment of neurological disorders and several other It is used to monitor patients during anesthesia during procedures, particularly during anesthesia. The device 101 is coupled to a patient 102 via a number of electrical leads 103. Each of the electrodes is coupled to an electrode (not shown) placed at an appropriate location on the patient's body. In applications where electrodes must be bonded to the body, the setup, i.e., placement and management of the electrodes, is Each electrode is placed in a different position to capture electrical activity in its vicinity. Since the input recorded by each electrode must be processed independently, Thus, the system recognizes the identity of each of the electrical leads 103 and processes them accordingly. The input received from the patient 102 must be processed. After placement in position, the user attaches the electrical leads 103 corresponding to each electrode to the medical device 101. The electrodes must be inserted correctly into the specific input channel configured for them. If there are fewer, say less than 10 or 15, the user must identify the electrodes and However, as the number of electrodes increases, this process This can be extremely difficult and error prone. Furthermore, even if the electrodes are in the correct position on the medical device 101, Even if it is coupled to an input slot, each connection is rechecked to verify its integrity before processing. In practice, this is extremely difficult and time-consuming. The setup process is time-consuming and in some situations, e.g. during a surgical procedure, The surgeon will complete or partially inspect each connection for completeness until the surgical procedure is complete. This would result in omissions from the medical staff, increasing the possibility of medical malpractice.

[0050] FIG. 2 illustrates an embodiment of a patient 202 having multiple electrodes positioned on the body. 2 shows a block diagram of an exemplary medical system 200 that can be used to treat multiple electrical The device comprises a number of electrodes (not shown) coupled to the body of the patient 202 via wires 203 . In neuromonitoring medical procedures such as EEG, these electrodes are grouped together The electrodes within a particular group are similar in terms of their input signals and locations. The systems and methods described herein also include multiple electrodes and corresponding electrical leads 203. The groups are arranged in a number of groups, for example 203a, 203b, ..., 203n. Each group is independently constructed to contain electrodes of similar type and position. In the present embodiment, instead of the medical device 201 directly connecting the electrodes placed, these electrodes are connected to multiple groups. The group is arranged in a loop, and each group is connected to the medical device 2 via a connector 205 having a unique ID. 01. Electrical leads 203a, 203b,...,203n (similar types) are and position electrodes) correspond to a corresponding connector 205a, 205b,... . . , 205n, the group of electrical leads 203a are coupled to connector 205a. , electrical lead 203b is connected to connector 205b, and similarly lead 203n is connected to connector 20 5n. The various connectors 205a, 205b,...,205n are connected to the medical device 2 10. The receiving socket 204 has an array of input points. , any of these inputs accepts connectors 205a, 205b,..., 205n Each of the connectors 205a, 205b,..., 205n has its own eye. The receiving socket 204 has a density such that any of such connectors can be connected to it. The system is configured to verify the identity of the connector when it is By verifying the identity of the data transfer device 205, the system 200 5, the various electrodes coupled to it, including their types and locations, can be identified. All electrodes coupled to a single connector 205 belong to the same group and therefore their signals are interchangeable with respect to signal processing requirements. The anatomical locations of the patient-connected electrodes are always in the same prescribed input order on the connector 205. Additionally, the receiving socket 204 can receive an optional connector 205 and therefore the group of electrodes coupled to the connector. These connectors are configured to identify the loops by their unique IDs, The input can be plugged into any input of the input 204.

[0051] In one embodiment, the connectors 205a, 205b,..., 205n are designated with a predefined identification. When any connector is plugged into the receiving socket 204, The socket 204 transmits a signal from its output pins to verify the identity of the connector 205. Once the identity of the connector 205 is confirmed, the system The system 200 recognizes the set of electrodes that are mapped to the connector and maps each electrode to its corresponding Configure itself to automatically correlate, associate, or map with input channels. Determine.

[0052] Manually map each electrode to its corresponding input channel in the medical device 201. Instead, using the concept of treating electrodes in independent groups as described above, The user ensures that electrodes belonging to the same group are connected to the same connectors in the same order. This means that the input is a portion of a mechanically defined grid or strip. This happens by default when a user receives a large number of such connectors. You can plug any of the electrodes into any of its inputs. You can manually map electrodes to input channels. The conventional process of matching the patient with the drug is extremely tedious and time consuming, but the disclosed method The disclosed system and method significantly reduce the set-up time required before beginning a therapeutic procedure. The method eliminates human involvement in the process of mapping electrodes to corresponding input channels. This also reduces the risk of making errors.

[0053] The number of electrodes coupled to any connector 205 can vary and depend on the actual medical need. Typically, only electrodes that are similarly located and receive similar input signals are grouped together. , can be combined into a single connector. In medical procedures such as EEG, electrodes are Divided into groups of 5, 6, 8, 10 and 16 electrodes, each of these electrode groups Targeting specific areas of the brain. In such cases, the above mentioned electrode groups are supported. There are a number of different sized connectors that can be arranged.

[0054] FIG. 3A illustrates an exemplary connector 300 and receiving socket 310 in one embodiment. As shown in FIG. 3A, the connector 300 is placed on the patient's body using the connector 300. The connector 3 has a plurality of signal output pins 302 corresponding to a plurality of electrodes (not shown) to be connected.

In an embodiment, each connector, such as connector 300, has a unique identity and is When electrodes are grouped together, This means that the input signals are of the same type and their relative positions are fully specified. These electrodes are connected to the input terminals of the connector in a specific, pre-determined order. FIG. 3A shows an “n” channel connector 300, which has a maximum number of electrodes, n. where n is any natural number.

The device has a row of signal input points or sockets 311. The socket has enough input points to accept a large number of connectors. In the actual application, the number of input points is more than 200. The receiving socket 310 controls the entire system. In one embodiment, the amplifier is coupled to a control unit / amplifier (not shown) that is used to The receiving socket 310 is configured to receive the ID output pin 301 of the connector 300. The connector 300 has an ID input receiving hole 312. The ID output pin 301 is The signal output pin 302 is received in a portion of the signal input receiving hole 311. 3A, the receiving socket 310 is inserted into the receiving socket 310. In this embodiment, the system includes a plurality of receiving sockets 310 and a plurality of connectors 300, and any of the connectors The connector 300 is connected to an arbitrary receiving socket 310, and the ID output pin 301 of the connector is connected to the corresponding ID input receiving pin. It can be inserted so that it aligns with and is inserted into the hole 312 .

[0056] Once the identity of the connector 300 is confirmed, the system couples to the connector 300. The type and location of all electrodes connected to the input receptacle 31 into which the connector 300 is inserted. 1. Once the electrode is identified, it is inserted into the receiving socket 310. The associated control unit automatically correlates each electrode to its corresponding input channel. Reconfigure the system to associate, assign or map.

[0057] Each connector, such as connector 300, has a unique ID (identity). This identification information is stored in the connector 300 and is output from its identification (ID) output pin 301 to the system. This ID information is accessible to the system and identifies the type and relative position of each electrode in the connector 300. In one embodiment, the ID field is a GUID (Globally Unique Identifier). ), the GUID is a standard format that contains 128 bits of data and is used by computers. The ID field is used by the software as an identifier. Once assigned a GUID, each input is then uniquely identified.
