Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lead wire relay device for relaying a lead wire between a main body of a biometric information collecting device such as an electrocardiograph and a bioelectrode for collecting biometric information from a living body.

[0002]

[Prior art]

 In recent years, the demand for electrocardiography has been increasing with the increase in heart disease. Above all, long-term electrocardiography is carried out by carrying a 24-hour electrocardiograph for the purpose of detecting transient arrhythmias. (Commonly known as Holter electrocardiography) is drawing attention.

This long-term electrocardiograph is composed of an electrocardiograph body attached to the waist of a subject, and an electrode section composed of a plurality of bioelectrodes connected to the electrocardiograph body via lead wires. It is composed of These electrodes are attached to the chest of the subject according to a predetermined guidance system (NASA guidance, CM5 guidance, etc.).

[0004]

[Problems to be solved by the device]

 However, this conventional long-term electrocardiograph is a test that gives a strong sense of restraint to the subject. That is, the electrocardiograph body is usually located on the waist of the subject, that is, outside the clothes, while each electrode is attached directly to the skin of the subject, and therefore the lead connecting the electrode and the electrocardiograph body is used. The wire is extended from the electrode part attached to the skin, through the gap between the underwear, and from the gap of the outerwear to the waist where the electrocardiograph body is located, and is worn.

As described above, in the conventional long-term electrocardiographic examination, it is necessary to attach a plurality of lead wires that are longer than necessary, and the examination must be performed all day (24 hours). It was very inconvenient for me to change my clothes.

The present invention has been made in view of the above problems, and an object thereof is to eliminate the inconvenience of a subject due to a lead wire in an electrocardiogram examination, and the inconvenience of changing clothes. An object is to provide a lead wire relay device for electrodes.

[0007]

[Means for Solving the Problems]

 The electrocardiograph according to the present invention includes a first relay section having a hole-shaped connection section electrically connected to one of the bioelectrode and the biometric information collecting device via a first lead wire, and a biometric unit. A first electrode that is electrically connected to the other side of the electrode or the biological information collecting device through a second lead wire and that has a needle-like connecting terminal that can be electrically connected to the hole-like connecting portion. And two relay units.

The hole-shaped connection portion is provided in the first relay portion and the hole portion formed corresponding to the needle-shaped connection terminal, and the hole-shaped connection portion is disposed in the first relay portion. It is composed of electrically conductive corresponding terminals whose sides can contact. Further, in the lead wire relay device of the present invention, the pressing plate provided facing the corresponding terminal, the external knob connected to the pressing plate, and the pressing plate elastically attached to the corresponding terminal direction. A connection terminal contact / separation mechanism including a biasing elastic member is provided.

With such a configuration, in the lead wire relay device of the present invention, the subject attaches each of the biomedical electrodes to a predetermined position on the chest and then attaches the needle-shaped connection terminals of the second relay portion, respectively. The underwear is made to penetrate from the back side and is held in a state of protruding above the underwear. Then, the needle-like connecting terminal protruding above the underwear is inserted into the hole-like connecting portion of the first relay portion. When the needle-shaped connection terminal is inserted into the first relay portion through the hole, the pressing plate presses the needle-shaped connection terminal against the corresponding terminal by the elastic force of the elastic member. As a result, the biological electrode and the biological information collecting device are electrically connected and mechanically held. Also, when it is necessary to separate the first relay section and the second relay section due to change of clothes etc., pulling the external knob causes the pressure plate to move against the elastic force of the elastic member. As a result, the pressure contact state between the second connection terminal and the corresponding terminal is released.

A cavity 30 is provided inside the first relay portion 12 as represented by the hole-shaped connection portion 27 in FIG. 1, and a second hollow portion is provided on the surface facing the second relay portion 13. A hole portion 31 through which the needle-shaped connection terminal 24 of the relay portion 13 can be inserted is formed. In addition, a conductive corresponding terminal 32 is disposed on the side wall of the cavity 30 at a position corresponding to the side surface portion of the needle-shaped connection terminal 24 inserted therein. The hole portion 31 and the corresponding terminal 32 form the hole-shaped connection terminal 27. A pressure plate 33 is arranged in the cavity 30 so as to face the corresponding terminal 32. The pressing plate 33 is connected to the external knob 34 through a through hole 35 formed in the side wall of the first relay portion 12. A spring 36 is disposed between the back surface of the pressure plate 33 and the inner side wall surface of the first relay portion 12, and elastically biases the pressure plate 33 toward the corresponding terminal 32. When the needle-like connecting terminal 24 is inserted through the hole 31, the pressing plate 33 moves the needle-like connecting terminal 24 in the direction B shown in FIG. 1 by the elastic force of the spring 36 and press-contacts the corresponding terminal 32. It is designed to hold the state. As a result, the lead wire 17 connected to the needle-shaped connection terminal 24 is electrically connected to the lead wire 20 via the corresponding terminal 32. Since the hole-shaped connecting portions 28 and 29 corresponding to the other needle-shaped connecting terminals 25 and 26 have the same configuration, the description thereof will be omitted.

For example, in the above-described embodiment, the electrocardiograph main body 23 side is connected to the first relay section 12 and the biomedical electrodes 14 to 16 side are connected to the second relay section 13, but this connection is reversed. It may be. That is, you may make it connect the bioelectrodes 14-16 side to the 1st relay part 12, and connect the electrocardiograph main body 23 side to the 2nd relay part 13. Further, the needle-like connection terminals 24 to 26 of the second relay portion 13 may be covered with safety caps when not in use in order to increase safety. Further, in the above-described embodiment, the connection terminal connecting / separating mechanism constituted by the pressing plate 33, the external knob 34 and the spring 36 is provided, but the needle connecting terminal 24 is not provided. 26 to 26 and the hole-shaped connecting portions 27 to 28 may be attached and detached.
