Description

DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) [Industrial Application Field] The present invention relates to a connector device for a plate-shaped electrode installed on the human body.

[Conventional technology]

When taking an electrocardiogram, plate electrodes are attached to appropriate positions on the human body, a connector is connected to the electrodes, and electrical signals are picked up through the connectors.

[Problem to be solved by the invention]

However, in the past, the connection between the electrode and the connector was a button type, so (1) pressure was applied in the direction of the human body when they were connected;
(2) Since the connector part protrudes after the connector is connected, if this connector part is caught between the testee and the bed, etc., it may cause discomfort to the testee. Each had their own disadvantages in providing pleasure.

An object of the present invention is to eliminate such disadvantages.

[Means to solve the problem]

In order to achieve the above object, the electrode member connector device of the present invention includes an electrode member, a connector member connected to the electrode member, and a hook and loop fastener member that detachably connects these. The fastener member consists of a receiving plate having loop fibers protruding from the substrate and a locking plate having locking fibers protruding from the substrate, and either the receiving plate or the locking plate is attached to the electrode member or the connector member. and the other is fixed to the connector member or the electrode member, and a through hole is formed approximately at the center of the substrate of the receiving plate and the substrate of the locking plate, and the electrode member and the connector member are configured. In doing so, the elastic member is surrounded by conductive foil, the electrode member or the connector member is fitted into the through hole of the substrate, and the electrode member or the connector member is connected to the loop fiber of the receiving plate or the locking member. The electrode member is made to protrude beyond the locking fibers of the plate, the electrode member is pressed into contact with the connector member, and the locking fiber of the electrode member or the connector member is locked with the loop fiber of the connector member or the electrode member. and the connector member are connected to each other.

Moreover, the elastic member can also be formed from a foamed urethane material.

[Action of the invention]

In the electrode member connector device configured as described above, the electrode member and the connector member can be brought into pressure contact only by adhering the hook-and-loop fastener member, and the electrical signal sensed by the electrode member can be transferred to the connector member. I can tell you. In this case, since an elastic member is installed inside the electrode member and the connector member, the pressing force when the electrode member is pressed into contact with the connector member is likely to be buffered by the elastic member.
