Description

Electrode unit for measuring electrophysiological signals

Technical Field

The present invention relates to an electrode unit, and more particularly to an electrode unit for measuring electrophysiological signals of a subject.

Background

The acquisition of the physiological electric signals of the human body can directly reflect the health condition of the human body. Electrocardiograph (ECG) information acquisition devices are widely used in clinical activities to monitor the physical condition of patients. Through the abnormal change of the electrocardiogram information, medical staff can find the abnormal condition of the patient in time, which is helpful for diagnosis and treatment.

To prevent cross-infection, disposable Ag/AgCl electrocardio-electrodes are often used, which are attached directly to the skin of the patient's body during use. The disposable Ag/AgCl electrocardio-electrode is fixed with a convex electrode part, and the convex electrode part and an electrode wire on the electrocardio-state analysis equipment form a connection relationship of a plug-in connection mode. However, such a protruding electrode structure may result in an electrocardio-electrode that is not compact enough in overall structure. In addition, the protruding electrode part is made of metal material with large mass, which may cause the electrode to shift along with the body movement of the patient, and is not suitable for the physiological study of athletes or some work needing diagnosis in the body movement state. Therefore, in the new design of the electrode unit for collecting the electrocardiographic signals, the structure of the electrode needs to be simplified as much as possible, so that one electrode unit can include as many electrocardiographic electrodes as possible for use. Meanwhile, a lightweight material may be used to increase comfort, breathability and waterproofness for long-term monitoring.

In some embodiments, the thickness of the base material 101 may be less than 0.5mm, for example. Thus, the base material 101 may include properties such as softness and/or light weight, resulting in a good user experience. For example, the thickness of the base material 101 may be set to about 0.4 mm. In some embodiments, the viscous gel dedicated to human skin may be supplemented with menthol to achieve cooling, antipruritic, antibacterial, and anti-inflammatory effects.

According to an embodiment of the present invention, the electrode 102 may comprise an electrocardio-electrode. The electrode unit 100 may include two electrodes 102, which may be symmetrically disposed on two sides of the position limiting module 105, so as to make the electrocardiographic signal more stable.

The plurality of connectors 103 may be separated from each other and evenly distributed inside the spacing module 105. The connector 103 may be connected with the electrode 102 via a conductive wire 104.

The conductive wires 104 may comprise resilient conductive wires. The conductive wire 104 may be a conductive wire wound with a metal wire such as a conductive nano silver wire and/or a conductive braid woven with polyester fibers. The elasticity of the conductive wires 104 may be equal to the elasticity of the base material 101, thereby maintaining the measurement stability of the electrode unit 100 when the muscle of the person is stretched.

In some embodiments, the components of the electrode unit 100 may all be made of an elastic material. Therefore, the resistance value between the skin of the object to be measured and the electrode unit 100 can be maintained substantially the same in different movement states of the object to be measured of the electrode unit 100. In some embodiments, the resistance between the electrode 102 and the connector 103 of the electrode unit 100 may remain substantially the same when the subject wearing the electrode unit 100 is bathing. In some embodiments, the resistance between the electrode 102 and the connector 103 of the electrode unit 100 may still not show a significant change after 24 hours of use. The resistance between the electrode 102 and the connector 103 of the electrode unit 100 may not significantly change in the chest-inflated or stationary state of the subject wearing the electrode unit 100.

In one embodiment, FIG. 2 illustrates a schematic cross-sectional structure of the electrode unit 100 shown in FIG. 1 along a centerline a-a'. As shown in fig. 2, the operational relationship between all components of one embodiment of the electrode unit 100 is shown. In fig. 2, the electrode unit 100 includes two layers of base materials 101 (including a first base material layer 101A and a second base material layer 101B), an electrode 102, a connector 103, a conductive wire 104, a spacing module 105, an adhesive tape 106, a film 107, and two pieces of release paper (including a first release paper 108A and a second release paper 108B).

According to an embodiment of the present invention, the electrode unit 100 is fixed on the skin of the subject by the first substrate layer 101A. A high quality medical pressure sensitive adhesive may be coated on the bottom surface of the first substrate layer 101A by a breathable coating process. In some embodiments, the first base material layer 101A may maintain viscosity for 3 to 5 days even in the case where the subject using the electrode unit 100 sweats. The first substrate layer 101A may include one or more through holes, which may be disposed at a large interval and uniformly distributed in the first substrate layer 101A. In some embodiments, the through-hole may be circular or square. As shown in fig. 2, the electrode 102 may be placed in a through hole in the first substrate layer 101A to contact the skin of the human body, and may be configured to collect electrocardiographic signals from a measured object such as a human body. The diameter of the through-hole in the first substrate layer 101A may be about 4mm to 19mm, and may be slightly smaller than the diameter of the electrode 102. Therefore, the electrode 102 can be stably inserted into the first base material layer 101A without being displaced.

One or more connectors 103 may be evenly distributed within the spacing module 105. As shown in fig. 2, for example, the two connectors 103 may be distributed within different ends of the spacing module 105.

In some embodiments, the connector 103 may be connected with the conductive wire 104 to establish an electrical connection. In one or more gaps between the connector 103 and the spacing module 105, the adhesive tape 106 may be used to reinforce the contact between the ecg signal acquisition device and the connector 103. The film 107 may be formed on the second base material layer 101B, covering the upper surface and edges of the electrode unit 100. The spacing module 105, connector 103 and tape 106 may be exposed through an opening in the film 107 for direct access. In some embodiments, the openings in the second substrate layer 101B and the openings in the film 107 may be aligned. The film 107 may be bonded directly to the second substrate layer 101B by the gelling agent. The first release paper 108A may cover the bottom of the electrode unit 100 and the edge of the film 107, and the second release paper 108B may cover the exposed surface inside the spacing module 105. The first release paper 108A and the second release paper 108B may have openings or protrusions so that the first release paper 108A and/or the second release paper 108B are easily peeled off in use. The first release liner 108A and the second release liner 108B may serve as a protective media for the electrode unit 100 when the electrode unit 100 is not used.

The present invention provides an electrode unit 100 that may have one or more advantages, such as a simple structure, light weight, and ease of use.
