The present specification generally relates to the field of electrical connections in medical devices and more specifically to a system and method for coupling a group of electrical connectors with their respective mating units.
Several medical procedures involve deploying multiple sensors on the human body for the recording and monitoring of data required for patient care. Information, such as vital health parameters, cardiac activity, bio-chemical activity, electrical activity in the brain, gastric activity and physiological data, is usually recorded through on-body or implanted sensors/electrodes which are controlled through a wired or wireless link. Typical patient monitoring systems comprise multiple electrodes that are coupled to a control unit of the medical system through electrical connectors. The various electrical connectors are coupled to their respective mating units or sockets located within the control unit. Several other medical apparatuses, which may not be specifically used for patient monitoring, also involve connecting multiple electrical leads with the control unit of the medical system. In all such medical systems involving a large number of electrical connectors, the overall set up, placement and management of connectors and the corresponding wire leads is a time consuming, cumbersome, and potentially inexact process.
Neuromonitoring involves the use of electrophysiological methods, such as electroencephalography (EEG), electromyography (EMG), and evoked potentials, to monitor the functional integrity of certain neural structures (e.g., nerves, spinal cord and parts of the brain) during surgery. Generally, neuromonitoring medical procedures such as EEG involve a large number of electrodes coupled to the human body. In an EEG procedure, the electrodes are used to record and monitor the electrical activity corresponding to various parts of the brain for detection and treatment of various ailments such as epilepsy, sleep disorders and coma. The EEG procedure is either non-invasive or invasive. In non-invasive EEG, a number of electrodes are deployed on the human scalp for recording electrical activity in portions of the underlying brain. In invasive EEG, through surgical intervention, the electrodes are placed directly over sections of the brain, in the form of a strip or grid, or are positioned in the deeper areas of the brain. The electrical activity pattern captured by various electrodes is analyzed using standard algorithms to localize or spot the portion of brain which is responsible for causing the specific ailment. In both invasive and non-invasive EEG, each of the electrodes is coupled to a wire lead which, in turn, is coupled through a respective electrical connector to a control unit adapted to receive and transmit the electrical signals. Medical procedures, such as EEG, usually involve “Touch Proof” electrical connectors which comprise a simple singe-conductor connector in which the metal part is completely shrouded in plastic. The EEG DIN connector also referred to as DIN 42802 or EEG safety DIN connector is a de facto standard for connecting medical and biomedical recording systems, such as electrodes to amplifiers and other medical devices. The two types of EEG DIN connectors usually include touch-proof sockets that surround in-line rigid plugs.
The current systems and methods used for coupling multiple electrical connectors, such as the touch-proof DIN connectors, with the control unit of a medical system suffer from several drawbacks. Firstly, connecting each individual electrical connector is a very time consuming process when the number of electrical connectors is large, as in the case of neuro-monitoring applications. Secondly, while connecting a large number of electrical connectors with their respective mating or receiving sockets, it is possible that the provider or clinician plugs an electrical connector into a wrong receiving socket. Thirdly, each electrical connector is independently coupled to its respective receiving socket and there is no support structure to ensure that the connector is not displaced or misaligned from its original position. Sometimes, the electrical connector may become displaced from its position and tend to partially protrude from the receiving socket leading to a loose electrical connection.
Such errors in electrode connection and placement while performing a medical procedure can negatively impact patient care. Ensuring the integrity of the system requires thorough testing to ensure that connections are correct. Therefore, in high density electrode configurations, the connection corresponding to each electrode needs to be separately established and verified for integrity before starting the procedure which increases the set up time. To save time, in practice, the provider or clinician may skip at least part of the testing procedure which can impact the quality of medical care.
Therefore, current medical devices involving a large number of electrical connections do not provide an easy and convenient way for a medical care giver to deploy such systems. These systems suffer from a significant risk of error due to unreliable measurements because of incorrect connections. Further, deployment of such systems is time consuming which hinders following best practices and therefore compromises the quality of medical care.
To ensure that medical devices work accurately, especially in critical applications, engineers must design systems that are reliable and maintain signal fidelity. Systems and devices are required which can provide a reliable interconnection between the electrodes deployed on the body of the patient and the control unit of the medical device.
Devices and systems are required which are convenient to use and do not consume too much time for deployment. Systems are required which enable the connection of multiple electrical connectors with their respective receiving units in groups rather than separately connecting each wire lead. Further, there is a need for interconnection structures which can support the electrical connectors in a correct position, thus preventing displacement and misalignment.
The following embodiments and aspects thereof are described and illustrated in conjunction with systems, tools and methods which are meant to be exemplary and illustrative, not limiting in scope.

The present specification describes an improved system and method for connecting electrical connectors to medical devices. Systems are disclosed through which the overall set up, placement and management of electrical connectors is convenient and less time consuming. In embodiments, the electrical connectors are handled in groups such that a group of electrical connectors is plugged into or removed from a corresponding receiving or mating unit located within a medical device as a single unit. The present specification discloses a Mass Connection Plate (MCP) which acts as an intermediate connector or enabler to quickly engage or disengage a group of electrical connectors with their respective receiving or mating units located within a medical device. As the electrical connectors are secured by the MCP as a group, the likelihood of plugging a connector in a wrong receiving socket on the medical device is significantly less than compared to that in the conventional systems in which connectors are individually and directly connected with their respective receiving sockets.
In embodiments, the MCP allows an electrical connector to be securely positioned so that the electrical connector does not pull or push free from its position upon insertion or removal of the connection plate from the medical device. In embodiments, the MCP is configured to be attached or detached form a corresponding medical device with a simple push or pull action, respectively.
In various embodiments, the shapes and dimensions of different sections of a MCP are customized based on corresponding shapes and dimensions of electrical connectors and the mating device.
The present specification is directed towards multiple embodiments. The following disclosure is provided in order to enable a person having ordinary skill in the art to practice the invention. Language used in this specification should not be interpreted as a general disavowal of any one specific embodiment or used to limit the claims beyond the meaning of the terms used therein. The general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the invention. Also, the terminology and phraseology used is for the purpose of describing exemplary embodiments and should not be considered limiting. Thus, the present invention is to be accorded the widest scope encompassing numerous alternatives, modifications and equivalents consistent with the principles and features disclosed. For purpose of clarity, details relating to technical material that is known in the technical fields related to the invention have not been described in detail so as not to unnecessarily obscure the present invention.
It should be noted herein that any feature or component described in association with a specific embodiment may be used and implemented with any other embodiment unless clearly indicated otherwise.
As shown in
The system disclosed in
The intermediate connection plate shown in
In the above embodiment, the electrical connectors 204 are shown as electrical male connectors and the mating units 205 are shown as the electrical female connectors, however in other embodiments, different possible configuration are used.
The middle planar section 301 comprises a front section 301a and a back section (not visible in the figure). The middle planar section 301 further comprises a top edge section 301e, a bottom edge section 301f, a first side edge section 301c and a second side edge section 301d. The middle planar section 301 is configured such that it comprises the above described series of hills 303 and valleys 304 along the first side edge section 301c and the second side edge section 301d.
The intermediate connection plate 300 is configured such that the proximal section of an electrical connector is received in a well 306 carved into ledge 305 and the distal section of the electrical connector passes through a corresponding valley 304 of the middle planar section 301 where it is received in one of the plurality of keyholes/receiving sections 310. Therefore, each matching combination of a well 306, a valley 304 and a keyhole/receiving section 310 together comprise a single, unified channel in the MCP 300 in which one electrical connector can be positioned. By way of example, in embodiments, the u-shaped portions or wells 306 positioned within the ledge 305 have a diameter ranging between 0.148 and 0.150 inches.
In embodiments, the various keyholes/receiving sections 310 are adapted to receive the distal portions of the electrical connectors respectively and also provide support to hold the electrical connectors firmly in their respective positions.
In embodiments, the intermediate connection plate 300 has a monolithic structure in which the various sections are all seamlessly coupled to each other through injection molding. In embodiments, the connection plate 300 is manufactured using plastic. In embodiments, the connection plate 300 is manufactured using impact resistant materials that can withstand a sudden high force or shock. In embodiments, the connection plate 300 is disposable.
The intermediate connection plate or mass connection plate 300 allows a user to quickly connect or disconnect a group of electrodes from a medical device as a single unit which makes the entire process of set up, placement and management of electrical connectors convenient and efficient. The system is especially helpful when a patient is required to be repositioned on the operating table. Further, as the electrical connectors are secured by the MCP 300 as a group, the likelihood of plugging a connector into an incorrect receiving socket on the medical device is significantly less than compared to that in conventional systems in which the connectors are individually and directly connected with respective receiving sockets.
The MCP 300 also holds the electrical connectors firmly in place and prevents individual connectors from partially protruding out of the receiving sockets. In embodiments, the MCP 300 comprises a plastic plate with custom designed geometries that allow the connectors to easily snap or lock into respective channels located in the MCP 300. Once a connector is snapped into its desired location, it is held there until all other connectors are also snapped into the mass connection plate. In typical conventional systems, the ungrouped connectors are individually fully inserted into the corresponding receiving sockets up to the large major diameter of the connectors. With the MCP 300, part of this typical insertion depth is utilized to fully snap onto the MCP 300 thereby allowing the connector to be slightly less than fully mated, while still making good/sufficient contact with the corresponding mating device. Usually, the insertion depth of connectors utilized for coupling them with a mass connection plate is equal to the corresponding thickness or depth of a mass connection plate. In some exemplary embodiments, the MCP 300 has a thickness or depth ranging between 0.395 inches and 0.605 inches. The typical insertion depth of a connector is 0.480 inches. If the connector has an insertion depth of at least 0.350 inches, the connector would achieve a good and sufficient contact with the corresponding mating device. Therefore, the thickness of the MCP, at the point of attachment with the connector, is preferably no greater than 0.130 inches, ensuring that at least 0.350 inches remains on a standard connector for mating to a corresponding device and achieving a sufficient connection. In other embodiments, the thickness of the MCP, at the point of attachment with the connector, accounts for no more than 24-27% of the length of the insertion depth of the connector, thereby leaving 73-76% of the length of the insertion depth left for mating with the corresponding device and achieving a sufficient connection.
The MCP 300 is further configured such that a support wall or rib structured in the form of hills 303 is used to help stabilize and align the connectors after they are fitted into the desired locations. The same support wall or rib is also used when removing the connectors out of their snapped-in positions by providing a fulcrum point. In the disclosed system, the electrical connectors are coupled with the MCP 300 and subsequently the MCP 300 is coupled with a medical device without additional tools. A loaded connection plate essentially forms a singular connection mechanism and is plugged or unplugged from an associated piece of medical equipment with a unitary simple push or pull action. In embodiments, the connection plate is plugged/unplugged by grasping and pushing/pulling the outmost edges of middle planar section comprising the hills 303. Accordingly, the connectors are sufficiently attached to the MCP through a friction fit such that they do not become disconnected when the loaded connection plate is pushed into, or pulled out of, the connection ports of the medical device. The connectors are able to be removed/unsnapped manually from their corresponding location on the MCP 300 and replaced individually as required. In
In embodiments, the MCP 300 comprises unique keying features which prevents the cross-wiring of various electrical connectors, such as, but not limited to recording electrodes and simulation electrodes. In embodiments, the exact dimensions of various sections or portions in the MCP 300 are customized for specific applications depending on the corresponding geometries of the electrical connectors and the receiving units.
The mass connection plate 400 shown in
Once a single connector 411 is positioned/snapped into its desired location on MCP 400 it is held there until all other connectors are also positioned into the MCP 400. The MCP 400 is configured such that support walls or ribs configured in the form hills 403 helps to stabilize and align the connectors after they are snapped into the respective channels.
In the system disclosed in
The mass connection plate 500 shown in
The various keyholes/receiving sections located on the back side of the MCP 500 are configured to receive the distal portions of respective electrical connectors 511 and provide support to hold the electrical connectors firmly in their position.
As shown in
In an embodiment, the present specification describes a method for connecting a group of electrical connectors with the connection ports of a medical device using the connection plate or mass connection plate of the present specification. Referring now to
Typically, as the connection plates or the MCPs are customized for specific medical applications and their sizes, shapes and other dimensions may vary depending on the corresponding sizes and shapes of medical connectors and connection ports being used in that specific medical application. Further, the MCPs can have different capacities depending on the number of electrical connectors that can fit into the various channels or grooves located in an MCP. The clinician selects an appropriate MCP depending on the type of electrical connectors and the medical device involved in the application and the number of electrical connectors to be coupled using the MCP. In some embodiments, the clinician may use multiple MCPs of same or different capacities to engage a large number of connectors with the corresponding connection ports of a medical device.
In embodiments, the MCP of the present specification comprises a middle planar section further comprising a plurality of protruding portions extending outward from at least one of the edge sections of the middle planar section wherein each protruding portion of the plurality of protruding portions is separated from an adjacent protruding portion of the plurality of protruding portions by a space and wherein each space is adapted to receive a middle portion of an electrical connector. Further, in embodiments, the MCP comprises a proximal portion coupled to the middle planar section and extending outward in a first direction that is substantially perpendicular to the plurality of protruding portions, wherein the proximal section comprises a first plurality of receiving areas adapted to receive a proximal portion of an electrical connector. Further, in embodiments, the MCP comprises a distal portion coupled to the middle planar section and extending outward in a second direction that is substantially perpendicular to the plurality of protruding portions and in opposition to the first direction, wherein the distal portion comprises a second plurality of receiving areas adapted to receive a distal portion of an electrical connector.
At step 553, the electrical connectors are positioned into the various slots/grooves provided in the MCP. In embodiments, in step 553, the electrical connectors are positioned so that a distal end of each individual electrical connector is positioned onto one of the receiving areas in the distal section of the MCP, a middle portion of each individual electrical is positioned onto one of the spaces in the middle planar section of the MCP and a proximal portion of each individual electrical connector is positioned onto one of the receiving areas in the proximal portion of the MCP.
At step 554, a loaded MCP comprising a group of electrical connector positioned into its channels/grooves is placed near the connection ports of the medical device. At step 555, the positioning of the MCP is fine tuned so that each electrical connector is aligned to a corresponding receiving port in the medical device. At step 556, the MCP is pushed towards the medical device to insert the connectors engaged with the MCP into the corresponding receiving ports of the medical device. Once the connectors are sufficiently inserted into the receiving ports of the medical device, an electrical connection is established between the electrical connectors and the medical device and the system is ready for operation.
As described above, a complete group of electrical connectors are inserted into a medical device with a single push action by using the mass connection plate of the present specification.
In some embodiments, because the MCP 700 has a symmetrical design, it would be possible to rotate the MCP 700 by 180 degrees and still plug it in the medical device leading to an incorrect connection. Therefore, in some embodiments, the presence of protruding portion 739 prevents any incorrect mating between MCP and medical device. The mass connection plates that are not symmetrical in design do not require a protrusion or protruding portion 739 as these plates will not connect/mate with device in an incorrect orientation.
In an embodiment, the thickness 738 of protruding portion 739 is equal to 0.298 inches.
In embodiments, the protruding portion 939 present on MCP 900 is offset from the centerline of the MCP and is configured to enter into a corresponding mating void present on the medical device when the MCP is connected in a correct orientation. In embodiments, the MCP 900 can be engaged with the device in only one specific orientation. In other orientations, the MCP 900 cannot engage with the medical device as the mating void on the medical device would not be aligned to receive the protruding portion 939.
In some embodiments, because the MCP 900 has a symmetrical design, it would be possible to rotate the MCP 900 by 180 degrees and still plug it in the medical device leading to an incorrect connection. Therefore, in some embodiments, the presence of protruding portion 939 prevents incorrect mating between MCP and medical device. The mass connection plates that are not symmetrical in design do not require a protrusion or protruding portion 939 as these plates will not connect/mate with device in an incorrect orientation.
In an embodiment, the thickness 938 of the protruding portion 939 is equal to 0.298 inches.
