Definitions

  • the invention relates to a diagnostic patch having the features of the preamble of claim 1.
  • the diagnostic patch here is used, for example, for the long-term monitoring of biological measured values.
  • a number of diseases can be identified by a characteristic course of certain physiological parameters. This characteristic course often occurs only intermittently and irregularly. Until the person has visited a doctor or clinic after the onset of symptoms, the onset has often subsided and the physiological parameter has returned to normal. It is then difficult to establish a measurement precisely at the moment when the irregular course of the physiological parameter recurs, especially since at this time an accurate diagnosis is regularly not yet established.
  • Diagnostic patches known from US 2009/0062670 A1 can be applied to the skin of the patient in such a situation and fundamentally make it possible to produce the measurement diagrams summarized under the term ExG.
  • This is a collective term for the respective recording of all medically relevant bioelectric signals such as electrocardiogram (ECG), electroencephalogram (EEG), electromyogram (EMG) and any other record of this kind.
  • ECG electrocardiogram
  • EEG electroencephalogram
  • EMG electromyogram
  • These diagnostic patches known from the prior art comprise, in addition to the support surface even an electronic system. The recording takes place continuously over a long period of time and is electronically stored on the diagnostic patch itself until the data is transmitted to a central computer, which performs a comprehensive evaluation and thus enables a diagnosis.
  • the problem underlying the invention is to design and further develop the diagnostic patches known from the prior art in such a way that both a more favorable production and an improved absorption of elastic loading are made possible.
  • a textile base ie an elastic carrier substrate which comprises electrically conductive fibers, together with a possibility of fastening on this elastic basis a more robust carrier for electronic components, leads to a design which is both low-cost and more robust.
  • a textile base - ie the part of the diagnostic patch which rests directly on the skin - is advantageous not only because it allows the realization of good elasticity properties and a favorable production, but also the formation of electrical lines and electrode surfaces in the textile This is made possible in particular by the fact that the textile comprises electrically conductive yarns, which perform precisely these tasks. In this way, formed lines and electrode surfaces then have the favorable elastic properties of the carrier substrate to the same extent and thus stand out from metal wires, which were simply glued to elastic plastics.
  • subclaims 2 and 3 are directed to the particularly advantageous embodiments, in which the particularly important electrodes and the lines to these are formed by conductive yarns of the textile.
  • the subject-matter of claim 6 offers the particular advantage that the effective surface of the conductive filaments is increased by the meandering arrangement of the electrically conductive warp threads, including the conductive yarns, which facilitates the formation of an electrode by these filaments.
  • the subclaims 8 to 10 relate to diagnostic patches, in which the carrier for the electronic components can be fastened particularly easily on the textile and also removed again. This not only makes it possible to reuse the carrier with the electronic components with different textile substrates, but also allows to separate the carrier with the electronic components for examination, e.g. to send to a clinic.
  • the dependent claims 1 1 to 17 in turn relate to a diagnostic patch with a support for the electronic components and describe particularly advantageous arrangements of electronic components on this support.
  • the dependent claims 20 to 24 characterize the advantageous attachment of other components on the textile.
  • the quality of the measurement regularly depends on the orientation of the connection between the electrodes relative to the actual signal path in the body, the course of which is not readily known.
  • the diagnostic patch according to the dependent claim 26 with three electrode surfaces allows a very good measurement of the desired bioelectric size regardless of the orientation of the diagnostic patch.
  • FIG. 1 A plan view of a second embodiment of a proposed diagnostic patch.
  • the diagnostic patches shown in the drawing are suitable for attachment to the skin of a patient, either alone or together with other diagnostic patches of the same construction, and are used to measure and record one or more ExG data.
  • the measured values include, in particular, the heart tension, from which an ECG is then formed.
  • the diagnostic patch can be worn over a longer period of time and therefore serves primarily to observe the relevant physiological values of the patient outside a clinic and even at the patient's home.
  • the diagnostic patch may also stimulate, such as administer an electrical pulse to the patient. This is for example in patients with craniomandibular dysfunction into consideration.
  • the diagnostic patch may notice a - often unconsciously - teeth grinding of the patient and emit an electrical pulse in response. The pulse is perceived by the patient and causes the teeth grinding to be deliberately avoided as a reaction.
  • the administered pulse can also directly trigger the intended muscle contraction.
  • the proposed diagnostic patch 1 comprises a base 2 with a connection structure 3 for a carrier 4 for electronic components.
  • the base 2 forms the substrate of the diagnostic patch 1 and represents that surface of the diagnostic patch 1 which rests directly or indirectly on the skin in such a way that it particularly carries out elastic deformation of the skin.
  • the base 2 can be bonded to the skin both partially and on its entire surface.
  • the carrier 4 is suitable for mounting electronic components 5 on it in the manner of a circuit board.
  • both a mechanical and an electrical connection between the base 2 and the carrier 4 is produced.

  • the base further comprises an electrical line system, which line system in turn comprises a first electrode surface 6 and a first electrical connection 7 between the connection structure 3 and the first electrode surface 6.
  • the first electrode surface 6 basically serves the indirect or direct detection of bioelectric signals, which then form the basis for the further functionality of the diagnostic patch 1. Equally well, the first electrode surface 6 and any other possible electrode surface can also be used for emitting an electrical signal, and in particular for stimulation as already described, as well as for stimulation of an organ. In this case, one and the same electrode surface, and therefore also the first electrode surface 6, may be suitable for detecting a bioelectric signal as well as for stimulation. This also applies to any existing further electrode surfaces.

Detachment of this part of the conduit system from the textile 2a is at the same time practically excluded.
  • the at least one conductor yarn produces the electrical connection 7 between the connection structure 7 and the first electrode surface 3.
  • This electrical connection 7 necessarily extends over a relatively long distance, since the electrodes of the diagnostic patch must be at a certain distance from each other for effective measurement.
