Description

【０００１】
【産業上の利用分野】
本発明は、心電図測定などに用いられる吸着電極に係り、特にリード線による装着部位からの脱落を防止することのできる吸着電極に関する。
【０００２】
【従来の技術】
生体の心電図測定などに用いられる吸着電極は、従来は図２に示すように、球状に形成された吸引部としてのゴム球１は、外側直径上において円筒状に形成されたゴム球取付金具２に取り付けられている。ゴム球取付金具２のゴム球１の外側に突出する一端には半球状に形成された吸着部としてのカップ３が気密に固定されており、ゴム球１とカップ３とのそれぞれの内部はゴム球取付金具２の内周を介して連通している。カップ３は通常洋白金属で形成されている。またゴム球取付金具２には心電図などの信号を外部に導出する誘導チップ取付部４が固定されている。
【０００３】
上記のように構成された吸着電極を被検者の皮膚に装着するときは、ゴム球１を圧縮した状態で被検者の皮膚に押し付けた後にゴム球１の押圧を解除する。この結果ゴム球１は復元力により膨脹し、カップ３内は負圧となって皮膚を吸着する。この状態でカップ３は皮膚に密着され心電図などの信号を取り出すことができる。
【０００４】
【発明が解決しようとする課題】
しかしながら上記のように構成された従来の吸着電極によると、誘導チップ取付部４のリード線接続部４ａが電極中心より大きく偏心してゴム球取付金具２に固定されているため、リード線を接続したときにリード線の反撥力により、皮膚表面に装着された吸着電極が脱落するおそれがあった。またリード線をリード線接続部４ａに固定するためのバネ部品が必要であった。
【０００５】
本発明はこのような状況に鑑みてなされたもので、連結されたリード線の反撥力により皮膚表面から脱落することを防止できる安価な吸着電極を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、本発明は、弾性部材で球状に形成された吸引部と、導電性部材で半球状に形成され、前記吸引部の内部と連通する吸着部とからなる吸着電極において、前記吸引部と前記吸着部とを導電性部材で管状に形成され、クリップが把持されるクリップ把持部で連結したことを特徴とする。
【０００７】
【作用】
上記の構成によると、クリップ把持部にリード線が接続されたクリップを把持させることにより、クリップが吸着電極の中心を把持する。またクリップはクリップ把持部に対して回転可能である。この結果、従来のようにリード線の引張りによるモーメント力が発生せず、皮膚表面に装着された吸着電極の脱落を少くすることができる。
【０００８】
【実施例】
以下、本発明の吸着電極の一実施例を図面を参照して説明する。
【０００９】
図１に本発明の一実施例の構成を示す。図１において、図２に示す従来例の部分に対応する部分には同一の符号を付してあり、その説明は適宜省略する。本実施例の特徴はゴム球１とカップ３とを金属管で構成されたクリップ把持部５で連結した点にある。クリップ把持部５の両端近傍の外周には突起５ａが形成されており、ゴム球１及びカップ３のクリップ把持部５との連結部には、それぞれ突起５ａが嵌合する凹部が形成されている。またクリップ把持部５のゴム球１とカップ３との間の長さはクリップ６を装着把持できる長さとなっており、クリップ６には心電図などの生体信号を外部に導出するリード線７が接続されている。
【００１０】
本実施例によれば、クリップ把持部５にクリップ６を把持させて吸着電極を被検者の皮膚に装着し、被検者の心電図などの生体信号をリード線７を介して外部に導出するとき、クリップ６が吸着電極の中心を把持し、しかもクリップ６はクリップ把持部５に対して回転可能であるので、従来のようにリード線の引張りによるモーメント力が発生せず、吸着電極の脱落を少くすることができる。
【００１１】
またクリップ６は他の使い捨て電極用のものを使用できるため、電極の種類に応じて誘導コードを取り替える必要がない。さらにクリップ把持部５は従来のゴム球取付金具２の形状を変更するのみで容易に製作することができる。しかも従来のゴム球取付金具２に必要であったバネ部が不要となるため、コストの低減を図ることができる。
【００１２】
上記実施例で示したカップ３は洋白金属などの金属で構成してもよく、柔軟導電ゴムなどの弾性部材で構成してもよい。
【００１３】
【発明の効果】
以上説明したように、本発明の吸着電極によれば、吸引部と吸着部とを導電性部材で管状に形成されたクリップ把持部で連結し、このクリップ把持部にクリップを把持させて生体信号を導出するようにしたので、リード線の引張りによるモーメント力が発生せず、電極の脱落を少くすることができる。しかも構造が簡単となりコストの低減を図ることができる。

[Industrial applications]
The present invention relates to a suction electrode used for electrocardiogram measurement and the like, and more particularly to a suction electrode capable of preventing a lead wire from falling off from a mounting site.
[0002]
[Prior art]
Conventionally, as shown in FIG. 2, an adsorption electrode used for measuring an electrocardiogram of a living body has a rubber ball 1 as a suction portion formed in a spherical shape, and a rubber ball mounting bracket 2 formed in a cylindrical shape on an outer diameter. Attached to. A hemispherical cup 3 as an adsorbing portion is airtightly fixed to one end of the rubber ball mounting bracket 2 protruding outside the rubber ball 1, and the inside of each of the rubber ball 1 and the cup 3 is made of rubber. It communicates via the inner periphery of the ball mounting bracket 2. The cup 3 is usually formed of nickel silver. Further, an inductive tip mounting portion 4 for guiding a signal such as an electrocardiogram to the outside is fixed to the rubber ball mounting bracket 2.
[0003]
When the suction electrode configured as described above is mounted on the skin of the subject, the rubber ball 1 is pressed against the skin of the subject in a compressed state, and then the rubber ball 1 is released from the pressure. As a result, the rubber ball 1 expands due to the restoring force, and the inside of the cup 3 becomes a negative pressure to adsorb the skin. In this state, the cup 3 is brought into close contact with the skin and can take out signals such as electrocardiograms.
[0004]
[Problems to be solved by the invention]
However, according to the conventional suction electrode configured as described above, since the lead wire connecting portion 4a of the guide chip mounting portion 4 is eccentrically larger than the center of the electrode and is fixed to the rubber ball mounting bracket 2, the lead wire is connected. Occasionally, the repelling force of the lead wire may cause the suction electrode attached to the skin surface to fall off. In addition, a spring component for fixing the lead wire to the lead wire connecting portion 4a was required.
[0005]
The present invention has been made in view of such a situation, and an object of the present invention is to provide an inexpensive suction electrode that can prevent the lead wire from falling off the skin surface due to the repulsive force of the connected lead wire.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention relates to a suction electrode comprising a suction portion formed in a spherical shape with an elastic member, and a suction portion formed in a hemispherical shape with a conductive member and communicating with the inside of the suction portion. The suction unit and the suction unit are formed in a tubular shape with a conductive member, and are connected by a clip holding unit that holds a clip.
[0007]
[Action]
According to the above configuration, the clip grasps the center of the suction electrode by causing the clip grasping portion to grasp the clip to which the lead wire is connected. The clip is rotatable with respect to the clip grip. As a result, a moment force due to the pulling of the lead wire is not generated unlike the related art, and the detachment of the suction electrode mounted on the skin surface can be reduced.
[0008]
【Example】
Hereinafter, an embodiment of the adsorption electrode of the present invention will be described with reference to the drawings.
[0009]
FIG. 1 shows the configuration of one embodiment of the present invention. In FIG. 1, portions corresponding to those of the conventional example shown in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted as appropriate. The feature of this embodiment lies in that the rubber ball 1 and the cup 3 are connected by a clip grip 5 formed of a metal tube. Protrusions 5a are formed on the outer periphery near both ends of the clip grip 5, and concave portions into which the protrusions 5a are fitted are formed at the connection portions of the rubber ball 1 and the cup 3 with the clip grip 5 respectively. . The length between the rubber ball 1 and the cup 3 of the clip gripper 5 is such that the clip 6 can be attached and gripped, and the clip 6 is connected to a lead wire 7 for guiding a biological signal such as an electrocardiogram to the outside. Have been.
[0010]
According to the present embodiment, the clip 6 is gripped by the clip gripper 5, the suction electrode is attached to the skin of the subject, and a biological signal such as an electrocardiogram of the subject is led out through the lead wire 7. At this time, since the clip 6 grips the center of the suction electrode and the clip 6 is rotatable with respect to the clip grip portion 5, no moment force is generated due to the pulling of the lead wire as in the related art, and the suction electrode falls off. Can be reduced.
[0011]
Further, since the clip 6 can be used for another disposable electrode, it is not necessary to replace the lead cord according to the type of the electrode. Further, the clip gripper 5 can be easily manufactured only by changing the shape of the conventional rubber ball mounting bracket 2. In addition, since a spring portion required for the conventional rubber ball mounting bracket 2 is not required, cost can be reduced.
[0012]
The cup 3 shown in the above embodiment may be made of a metal such as nickel-plated metal, or may be made of an elastic member such as a soft conductive rubber.
[0013]
【The invention's effect】
As described above, according to the suction electrode of the present invention, the suction portion and the suction portion are connected by the clip holding portion formed in a tubular shape by the conductive member, and the clip is held by the clip holding portion. Is derived, no moment force is generated due to the pulling of the lead wire, and the falling off of the electrode can be reduced. In addition, the structure is simplified, and the cost can be reduced.
