- the provided systems and methods allow identification of whether an electrode is in fact compatible with a specific medical device. The results can be used to control the use of the electrode with that medical device. Accordingly, the use of electrodes outside their recommended uses can be prevented or reduced.
- the provided systems and methods further enable tracking of the use of electrodes with medical devices, and tracking of the performances of the electrodes when used with different medical devices. Accordingly, the compatibility of different electrodes with different medical devices can be further assessed and analysed over time, so that future use of the electrodes may be optimised or improved based on their previous performances.
- the provided systems and methods further allow monitoring of abnormalities that occurred during the use of the medical electrodes.
- the monitoring results and the abnormalities detected can be subsequently reported to the manufacturer of the electrodes. This provides a more effective and efficient way of performance monitoring and quality control for electrode products, and allows product improvements to be implemented in a timely manner.
- the trackable electrode device 100 includes at least one electrode member 110 (which may also be referred to as a "medical electrode” or “traditional electrode”) and a radio- frequency (RF) tag 120.
- the electrode member 110 and the RF tag 120 are attached or fitted in proximity to each other within or upon a substrate 130.
- the substrate 130 attaches the electrode member 110 to the RF tag 120, i.e., holds the electrode member 110 and the RF tag 120 together.
- the substrate 130 can be made from one or more flexible materials, e.g., cloth, paper, plastic or foam.
- the substrate 130 may be separable from the electrode member 110 and the RF tag 120, i.e., the substrate 130 may be removed from the electrode member 110 and the RF tag 120 during use by a person.
- the substrate 130 may be in the form of a removable sheet or cover that is removed by a clinician or operator before or after applying the electrode member 110 to the patient or connecting it to the medical device.
- This form of the substrate 130 may be referred to as a“removable substrate”, which is discussed in further detail below.
- this removable substrate holds the electrode member 110 and the RF tag 120 in a preselected arrangement; then the removable substrate is removed from the electrode member 110 and/or the RF tag 120 for application to (and generally adhesion to) the subject’s skin or the external medical device.
- the RF tag 120 may have its own adhesive/backing independent of the electrode member 110, so once the removable substrate is removed, the electrode member 110 and/or the RF tag 120 are no longer attached to and held by the substrate 130.
- the substrate 130 may remain integral with the electrode member 110 and the RF tag 120 during use, i.e., the substrate 130 is not removed from the electrode member 110 and the RF tag 120 during use.
- the substrate 130 may be in the form of a flexible pad or sheet integrated with the electrode member 110. This form of the substrate 130 may be referred to as an “integral substrate”. This is described in further detail below.
- the trackable electrode device 100 further includes a non electrode adhesive pad for facilitating securing the medical device to the patient's body, and/or to the medical electrodes members.
- the RF tag 120 may be embedded or accommodated in the non electrode adhesive pad.
- the non-electrode adhesive pad may be located at or proximate to the centre of the trackable electrode device 100, or any other location on the trackable electrode device 100 that allows the RF tag 120 to communicate with an external RF reading device.
- the electrode member 110 may have the same structure as a known medical electrode device.
- the electrode member 110 includes a flexible sheet 210 that is adaptable to the contour of the skin of a patient.
- the flexible sheet 210 is made of an insulating material, e.g., cloth, plastic, closed cell foam, or any other suitable insulating material.
- the electrode member 110 further includes an adhesive layer 220 containing a sticking substance on one side of the flexible sheet 210, for securing the flexible sheet 210 to the skin of the patient.
- the sticking substance is referred to as an adhesive, which may include but not be limited to acrylic, silicone, and polyurethane based adhesives.
- the electrode member 110 further includes a removable cover 222, which may form the (removable) substrate 130, that covers the adhesive layer 220 during storage, and which is removed by a clinician shortly before applying the adhesive layer 220 to the skin of the patient.
- the conductive area 230 is formed of conductive substance that can electrically connect the skin of the patient with an electrode connector 240 (also referred to as an“electrode- side connector” herein), the conductive substance being, e.g., conductive hydrophilic gel.
- the electrode- side connector 240 is made of a conductive material (e.g., metal), and may be a fastener, and in some embodiments has a shape similar to a male/female snap fastener, or has the form of a tab, wire or custom connector, and can be electrically connected, via a flexible conductive cable (also known as a "lead") or directly, to an external medical device that monitors or generates electrical signals.
