Definitions
- the invention relates to a method of through-contacting an electrically insulating substrate, e.g. a carrier foil for a medical electrode.
- an electrically insulating substrate e.g. a carrier foil for a medical electrode.
- Another form of via provides the attachment of contact rivets e.g. in the manufacture of medical off-center electrodes, but in many cases, insulation problems with it, since the lower part of the rivet must be performed as well as the top electrically conductive and this can have a negative impact on the measurement result.
- the object of the invention is to simplify the füriervorgang of one side of a carrier film to another and to reduce the production cost.
- connection paths can be used to cause the electrical conduction between the two sides of the carrier material.
- the galvanic contact can be produced in an edge region of the carrier material by excess printing of the carrier material or mutual spraying of an electrically conductive material.
- the electrically conductive material comes through excess application, whether printing or spraying, over the edge region of the one side of the substrate to the other in connection and this compound remains permanently after the drying or curing process of the electrically conductive material.
- the galvanic contact can be produced by excess printing of the carrier material or mutual spraying of an electrically conductive material in the region of a through-hole, a perforation or a perforation of the carrier material.
- the excess application establishes the connection between the two sides of the carrier material through the respectively existing or formed holes.
- the galvanic contact by excess printing of the carrier material or mutual spraying of an electrically conductive material in the region of pores or openings of the Carrier material can be produced.
- the pores or openings can be generated artificially in the carrier material or already be present in this, so that the conductive material can penetrate during printing or spraying the substrate for the purpose of producing the galvanic contact.
- the printing process can be designed so that the carrier material is first printed on one side and then on the other side or on both sides at the same time with the electrically conductive material, so that the printed material on one side of the printed material on the other side in the area touches the executed galvanic contact.
- the invention relates to a medical electrode having a carrier material, which has a galvanic plated-through from a first side to a second side of the carrier material.
- the commercially available electrodes today consist of one or more layers of materials. Usually, the lowermost layer is a foam or paving material that is glued directly to the skin. On it is again a carrier material which contains the actual skin contact element, e.g. from Ag / AgCl.
- a principal problem in the design of an electrode based on a substrate is that the actual skin contact element lies on the skin-facing side of the substrate, whereas the cable termination must be applied on the side facing away from the skin. So it must be made a galvanic contact between the two sides of the substrate.
- the object of the invention is therefore to provide a medical electrode in which the via can be performed by simple technical means.
- the galvanic via is formed by on both sides of the substrate made of an electrically conductive material from excessively applied printing or spraying in the region of at least one through hole or an edge region of the carrier material.
- the invention further relates to a medical electrode for attachment to the skin surface, e.g. an ECG electrode, with a skin contact element and a cable contact point, which are arranged on a carrier material spaced from each other and are electrically connected to each other via a galvanic via in the substrate.
- a medical electrode for attachment to the skin surface e.g. an ECG electrode
- a skin contact element and a cable contact point which are arranged on a carrier material spaced from each other and are electrically connected to each other via a galvanic via in the substrate.
- Medical electrodes according to the invention can serve both the signal detection on the human skin and the signal input into the skin.
- ECG electrodes are described by way of example in the context of this application, but the invention relates to all medical electrodes for attachment to the skin.
- Electrodes of the type mentioned are, for example, off-center electrodes, so named because the cable contact point not centrally above the skin contact element, eg consists of a printed Ag / AgCl contact surface. Off center electrodes have certain advantages over centered electrodes in terms of operation and measurement reliability, and are therefore widely used.
- a contact rivet is provided for these types of electrodes for the purpose of the through-connection from the side of the carrier material on which the cable contact point is present to the patient-facing side on which the skin contact element is mounted an electrically conductive rivet shell and a likewise conductive rivet base is composed.
- the object of the invention is therefore to avoid the difficulties mentioned and to specify a production technology easily feasible and reliable type of plated through hole for an aforementioned electrode.
- this is achieved in that the galvanic plated through by on both sides of the carrier material of a electrically conductive material applied overshadowing printing or spraying in the region of at least one through hole or an edge region of the carrier material is formed.
- This type of plated through-hole by means of coating on both sides of the carrier material can be done simultaneously with the printing or spraying of the carrier material for the formation of contact paths on the surface of the carrier material and is therefore feasible without much effort. It can be dispensed with a completely continuous conductive design of the contact rivets, which insulation problems with respect to the patient's skin can be avoided.
- the base layer can be provided with a recess, through which the riveting can be made subsequently, after the double-sided printed or spattered carrier material has been glued. This makes it possible to use devices that are used for the production of centered electrodes.
- the at least one through hole which is printed or sprayed according to the invention from both sides, can be formed by an opening, by a porous region, a perforation or a perforation or the like of the carrier material.
- a first contact area may be formed on the first side of the carrier material and a second contact area may be formed on the second side of the carrier material, which are interconnected via the galvanic via, and the skin contact element may be formed as a circular area on the second side of the carrier material and with the second contact area to be electrically connected via a connecting path.
- the first and the second contact region in each case extend annularly around the boundary of the through hole on the first and on the second side of the carrier material.
- a further feature of the invention may in this context be that the rivet base is formed electrically insulating.
- the electrically conductive upper part is electrically insulated from the skin of the patient by the electrically insulating lower part and no further measures have to be taken to avoid a falsification of the measurement result.
