Thereby, attachment / detachment of a contact electrode and a clip is made easy.

JP 2003-10138 A

  By the way, since the contact electrode attached to the chest is in conductive contact with the living body, an electrical conduction path is formed between the contact electrode and the contact electrode when the contact electrode is in contact with surrounding electrical equipment for some reason. It is desirable to avoid this as much as possible. Even if a conduction path is formed, in most cases, a dangerous current rarely flows. However, in the unlikely event that it comes into contact with a ground terminal or a terminal of an electrical outlet, an unnecessary current may flow.

  On the other hand, in the conventional electrode clip, the contact holding the electrode terminal portion is exposed above, so that a part of the exposed contact or the tip portion of the electrode terminal portion sandwiched between the contacts is around There was a possibility of contact with some of the electric appliances, especially the earth terminal and the electrical outlet, and there was a problem with safety in a strict sense.

  In addition, because the contacts and electrode terminals are exposed, they are susceptible to noise from fluorescent lights in rooms where ECG examinations are performed, rubbing clothes, water droplets, or dust, and are not required for detected signals. There is a problem that an accurate electrocardiogram signal cannot be obtained due to the addition of a simple signal.

  The present invention has been made in view of the above points, and is easy to attach to and detach from a contact electrode attached to a living body, and ensures electrical safety, and biological information such as an electrocardiogram is affected by noise. It is an object of the present invention to provide a biological information acquisition clip that is difficult to detect accurately.

One aspect of the biological information acquiring clip of the present invention has a first holding piece and a second holding piece facing each other, and a protrusion of an electrode attached to a living body by opening and closing the first holding piece and the second holding piece. A clip portion that sandwiches the terminal portion and electrically connects the terminal portion to a signal conductor provided on at least one of the first sandwiching piece and the second sandwiching piece, and above the clip portion, the provided apart from the signal conductors, have a, and the planar conductive member that shields the clip portion, the conductive member along the opening and closing direction of the first clamping piece and a second clamping piece, and, taking disposed Ru configured to cover the connecting portion opposite the connecting portion between the signal conductor and the terminal portion.

  ADVANTAGE OF THE INVENTION According to this invention, while being easy to attach or detach to the contact electrode attached to a biological body, electrical safety can be ensured and biological information, such as an electrocardiogram, can be accurately detected without being affected by noise.

  Usually, the contact electrode 40 is used by being directly attached to a living body (here, the skin of the chest of the subject). For this reason, a disposable electrode is used as the contact electrode 40 used in the present embodiment. This prevents the contact electrode 40 itself from being reused, prevents infection to other subjects, gives the subject a sense of hygiene and eliminates anxiety.

  The contact electrode 40 has a structure in which a soft conductive pad 44 is provided on one surface of a thin sheet-like base pad 42 and a protruding terminal portion 46 is provided on the other surface. Furthermore, one surface (back surface) 42a of the base pad 42 has adhesiveness so that conductive contact with the living body can be easily performed.

  Before use, a removable tape is stuck on the back surface 42a which is the adhesive surface of the base pad 42. The terminal portion 46 is provided so as to protrude from the conductive pad 44, and is exposed to the outside through the other surface (front surface) 42 b of the base pad 42. The terminal portion 46 includes a neck portion 46a sandwiched by a connector such as the biological information acquisition clip 100, and a head portion 46b formed at the tip of the neck portion 46a and having an outer diameter larger than the outer diameter of the neck portion 46a. .

  When the contact electrode 40 configured as described above is used, the tape on the back surface 42a of the base pad 42 is peeled off, and the adhesive surface (back surface 42a) of the base pad 42 is brought into contact with and adhered to the skin. By this adhesion, the conductive pad 44 also comes into contact with the skin surface, and the electric pulse from the measurement site is detected by the conductive pad 44. The electrical pulse is sent to a biological information acquisition device such as an electrocardiograph via the conductive pad 44, the terminal portion 46, the biological information acquisition clip 100, and the cable 30, and is displayed. Waveform analysis is also performed.

  The biometric information acquisition clip 100 includes a clip portion 110 that holds the terminal portion 46, an external electric light such as static electricity due to a fluorescent lamp in a room for performing an electrocardiogram examination, rubbing clothes, etc. And a conductive member 180 that shields noise.

  2-7 is a figure which shows the structure of the clip 100 for biometric information acquisition which concerns on this Embodiment.

  As shown in FIGS. 2 to 7, the biological information acquisition clip 100 is fixed to the distal end portion 31 of the cable 30.

  The biometric information acquisition clip 100 includes a first clamping member 120 and a second clamping member 130 that are coupled to each other at the connecting portion 101. The first holding member 120 and the second holding member 130 protrude forward from the connecting portion 101, protrude rearward from the first holding piece 122 and second holding piece 132 facing each other and the connecting portion 101, and are formed on the outer surface. And knobs 124 and 134 in which depressions are formed. In addition, a biasing member (compression coil spring) 140 that biases the first clamping piece 122 and the second clamping piece 132 in contact with each other, that is, in the closing direction, is interposed between the knobs 124 and 134. ing.

  The first clamping member 120 and the second clamping member 130 are formed of an insulating material, for example, a synthetic resin such as plastic or a hard resin having an insulating property, together with the connecting portion 101. In the normal state, the first sandwiching member 120 and the second sandwiching member 130 are arranged so that the knobs 124 and 134 are spaced apart in the left-right direction, and the first sandwiching piece 122 and the second sandwiching piece 132 are in contact with each other. It has become a state. In the first clamping member 120 and the second clamping member 130, the direction in which the knobs 124 and 134 are brought closer to each other against the biasing force of the biasing member 140, that is, the arrow direction indicated by the solid line C (FIG. 3). The first clamping piece 122 and the second clamping piece 132 that are directly connected to these are opened to the left and right (opened in the direction of arrow D).

  The 1st clamping piece 122 and the 2nd clamping piece 132 clamp the protrusion-shaped terminal part 46 of the contact electrode 40 shown in FIG. At least one of the first sandwiching piece 122 and the second sandwiching piece 132 comes into contact with the terminal portion 46 when the first sandwiching piece 122 and the second sandwiching piece 132 sandwich the terminal portion 46, and from the terminal portion 46. A signal conductor (here, a plate-shaped signal conductive plate) 150 is provided.

  Here, the signal conductor 150 is composed of metal plate-like contacts 152 and 154 whose centers are cut out in a V shape in plan view (see FIGS. 3 and 4). As shown in FIGS. 2, 3 and 6, the signal conductor 150 (plate-like contacts 152, 154) has a semicircular arc shape with the V-shaped notches 152a, 154a facing each other in the horizontal direction. The first sandwiching piece 122 and the second sandwiching piece 132 that are formed are respectively attached to the lower portions.

  With this configuration, when the first sandwiching piece 122 and the second sandwiching piece 132 sandwich the terminal portion 46, the V-shaped notches 152a and 154a of the respective plate-like contacts 152 and 154 are connected to each other. The neck 46a is sandwiched and brought into contact with the neck 46a (see FIG. 6).

  As shown in FIGS. 2 and 6, at least one of the plate-like contacts 152 and 154 (here, the plate-like contact 152) is connected to the signal line 32 that is a core wire of the cable 30.

  The clip part 110 (refer FIG. 1) is comprised by the 1st clamping piece 122, the 2nd clamping piece 132, and the signal conductor 150 (plate-like contact 152,154). A conductive member 180 is provided above the clip portion 110 so as to be separated from the plate contacts (signal conductor 150) 152, 154.

  The conductive member 180 covers the clip part 110 at the top, and is formed of a sheet material (conductive sheet) or a conductive film having a conductive property that can be expanded and contracted here. The conductive member 180 is made of an elastic material such as rubber, and has a semi-elliptical shape in plan view as shown in FIG. The conductive member 180 may have any shape as long as it covers the clip portion 110, and may have a fan shape in plan view.

  The conductive member 180 is embedded in the first clamping member 120 and the second clamping member 130 as an upper part of the clip part 110 and as a part of the clip part 110 by insert molding or double molding. The first holding member 120 and the second holding member 130 are integrally formed.

  Since the conductive member 180 made of a conductive sheet that can be expanded and contracted in this way, as shown in FIG. 7, when the first clamping piece 122 and the second clamping piece 132 are separated from each other, that is, when both are opened. However, it expands and contracts according to the shape in this state. Therefore, the conductive member 180 itself does not hinder the opening and closing of the first sandwiching piece 122 and the second sandwiching piece 132, and the plate-like contacts 152 and 154 and the terminal portion 46 in the clip portion 110 and the outside (opposite to the living body). Can be electrically shielded from the outside).

  The conductive member 180 is provided on the biological information acquisition clip 100 by insert molding or double molding. Here, the conductive member 180 is formed integrally with the clip portion 110. The upper surface of the conductive member 180 is covered with a material that elastically deforms and expands and contracts more easily than the material forming the first sandwiching piece 122 and the second sandwiching piece 132, and the biological information acquisition clip 100 is attached to the terminal portion 46. In the applied state, the conductive member 180 is not exposed to the outside. The conductive member 180 is connected to the shield wire 36 of the cable 30.

  Here, the configuration of the cable 30 is shown.

  FIG. 8 shows a cross-sectional view of the cable 30. As shown in FIG. 8, the cable 30 to which the biological information acquisition clip 100 is fixed has a signal line 32 disposed in the center, and the signal line 32 is covered with an insulating covering material 34. A conductive shield wire 36 is disposed on the outer periphery of the material 34. Further, the shield wire 36 is covered with an external insulating covering material 38 that serves as an outer cover of the cable 30.

  As shown in FIG. 2, the signal line 32 of the cable 30 is arranged in the biological information acquisition clip 100 from the rear end portion of the first holding member 120, that is, from the rear end surface of the knob portion 124 into the knob portion 124. It is installed. Thus, the signal line 32 arranged in the knob portion 124 is inserted through the inside of the first holding member 120 (the knob portion 124), and the tip portion (first holding piece 122) of the first holding member 120 is inserted. It is joined to the plate contact 152 (see FIG. 6).

  On the other hand, as shown in FIG. 2 and FIG. 5, the shield wire 36 is inserted into the biological information acquisition clip 100 from the rear end portion of the second holding member 130, that is, from the rear end surface of the knob portion 134 into the knob portion 134. It is arranged. Thus, the shield wire 36 disposed in the knob 134 is joined to the conductive member 180 from the second holding piece 132 side.

  Thus, the signal line 32 is led out from the biometric information acquisition clip 100 on the first clamping member 120 side, and the shield line 36 is led out from the biometric information acquisition clip 100 on the second clamping member 130 side. . Therefore, the signal line 32 and the shield line 36 of the cable 30 are connected to the plate-like contacts 152 and 154 and the conductive member 180 through completely different paths, and the signal line 32 is connected to the shield line 36. There is no.

  When using the biological information acquisition clip 100 of the present embodiment, first, the contact electrode 40 is brought into contact with the living body (here, the skin of the subject).

  On the other hand, the biological information acquisition clip 100 is moved and held in a direction in which the biasing members 140 approach each other against the biasing force (direction of arrow C shown in FIG. 3). Thereby, the 1st clamping piece 122 and the 2nd clamping piece 132 rotate to the direction (arrow D direction shown in FIG. 3) mutually spaced centering on the connection part 101, and the clip part 110 will be in an open state. And the terminal part 46 of the contact electrode 40 is located between the 1st clamping piece 122 and the 2nd clamping piece 132, and holding | maintenance of the knob | pick parts 124 and 134 is cancelled | released. Then, by the urging force of the urging member 140, the knobs 124 and 134 move in the normal direction (arrow F direction), and accordingly, the first clamping piece 122 and the second clamping piece 132 approach each other. It moves in the direction (arrow E direction shown in FIG. 3).

  As a result, the terminal portion 46 is sandwiched between the first sandwiching piece 122 and the second sandwiching piece 132 via the respective plate-like contacts 152, 154, and the terminal portion 46 and the plate-like contacts 152, 154 are brought together. Connect electrically. At this time, the plate-like contacts 152 and 154 sandwich the neck 46a of the terminal portion 46 between the V-shaped notches 152a and 154a, and the head 46b is hooked on the plate-like contacts 152 and 154. It becomes a state. As a result, the terminal portions 46 are not electrically disconnected from the plate contacts 152 and 154 and are electrically connected to each other.

  Further, the plate contacts 152 and 154 and the terminal portion 46 are connected in the clip portion 110, and the connection portion is covered with a conductive member 180 covering the clip portion 110 at the upper portion of the clip portion 110.

  As a result, the electric pulse from the terminal portion 46 of the contact electrode 40 (see FIG. 1) is output to the signal line 32 via the plate-like contacts 152 and 154 shielded by the conductive member 180. The signal line 32 is covered with an external insulating covering material 39a at the branch cable 31a (see FIG. 2) at the distal end portion 31 of the cable 30, and is covered with an insulating covering material 34 (see FIG. 8) inside the cable 30. The electric pulse from the terminal unit 46 is guided to the biological information acquisition device or the like via the signal line 32. Note that the branch cable 31b (see FIG. 2) that branches together with the branch cable 31a (see FIG. 2) at the distal end portion 31 of the cable 30 is configured by covering the shield wire 36 with an external insulating covering material 39b.

  As described above, in the biological information acquisition clip 100, the plate-like contacts 152 and 124 of the clip portion 110 connected to the contact electrode 40 (specifically, the terminal portion 46 of the contact electrode 40) are covered with the conductive member 180. Thereby, since the connection part of the plate-shaped contacts 152 and 124 and the contact electrode 40 is not exposed outside, it does not contact surrounding electric appliances.

  Moreover, since this connection part is covered with the electrically-conductive member 180, the noise to the connection part by the static electricity of the surrounding electrical appliance can be shielded. Therefore, when an electrocardiogram is performed using the biological information acquisition clip 100, it is due to noise caused by fluorescent light or commercial power supply in the room where the electrocardiogram is performed, static electricity due to rubbing of clothes, adhesion of water droplets, adhesion of dust, etc. The detected signal can be accurately output to the cable without receiving noise, and an accurate electrocardiogram signal can be obtained.

  In addition, the biological information acquisition clip 100 includes a sheet-like conductive material provided on the upper part of the clip part 110 including plate-like contacts 152 and 154 that are signal conductors 150 on the first holding piece 122 and the second holding piece 132 that open and close to the left and right. The member 180 is arranged and the clip member 110 is covered with the conductive member 180. For this reason, the biological information acquisition clip 100 can realize a configuration in which the thickness in the vertical direction with respect to the contact electrode 40 is made as thin as possible so as not to receive external noise.

  Furthermore, since the clip 100 for biometric information acquisition is configured to be connected to the contact electrode 40 by sandwiching the terminal portion 46 of the contact electrode 40 between the first sandwiching piece 122 and the second sandwiching piece 132 in the clip portion 110, It can be easily attached and detached. Thus, unlike a conventional press-fit electrode connecting portion (for example, a hook-type electrode disclosed in Japanese Patent Application Laid-Open No. 2003-10138) that is connected to the terminal portion 46 of the contact electrode 40 by press-fitting, the contact electrode 40 is attached / detached. Does not cause discomfort to the patient. In the conventional press-fit type electrode connection part, when pressing and attaching to the contact electrode, the patient's skin is pressed through the contact electrode 40, or the electrode connection part is moved in the direction opposite to the press-fitting direction to move from the contact electrode. In order to remove, the skin may be pulled through the contact electrode 40.

  In the present embodiment, a conductive member 180 made of a stretchable conductive sheet is provided integrally with the clip part 110 at the upper part of the clip part 110. However, the present invention is not limited to this. That is, in the clip part 110, if the conductive member 180 that shields noise from the outside is provided so as to cover the clip part 110 above the connection part between the contact electrode 40 and the plate contacts 152, 154 by clamping, Any configuration may be adopted. Further, the conductive member 180 may be provided to the clip portion 110 so that the connection portion between the clip portion 110 and the terminal portion 46 can be exposed. For example, the conductive member 180 is disposed above the clip portion 110 so as to be rotatable in a horizontal direction from a position covering the connection portion above, or slidably disposed from the same position, or to the clip portion 110. It may be configured to be attached to a lid that opens and closes in the vertical direction.

  Here, a modification of the biological information acquisition clip is shown in FIG. In addition, this biological information acquisition clip differs from the biological information acquisition clip shown in FIG. 1 only in the mounting state of the conductive member, and the other basic configurations are the same. Therefore, the same components are denoted by the same reference numerals, and description thereof is omitted.

  The biometric information acquisition clip 100A shown in FIG. 9 has a first clamping member 120A and a second clamping member that are openable and closable with the first clamping piece 122A and the second clamping piece 132A formed at the distal end with the connecting part 101A as a fulcrum. 130A is provided.

  The first clamping member 120A and the second clamping member 130A have the same basic configuration as the first clamping member 120 and the second clamping member 130 of the biological information acquisition clip 100. That is, the first clamping member 120A and the second clamping member 130A are formed of an insulating material, here, plastic, and knobs 124 and 134 are formed at the respective rear end portions. In the first sandwiching member 120A and the second sandwiching member 130A, the first sandwiching piece 122A and the second sandwiching piece 132A at the distal end are rotated in directions away from each other by bringing the knobs 124 and 134 closer to each other. That is, the clip portion 110A is in an open state. In addition, the clip portion 110A has a plate-like contact (not shown), like the clip portion 110 of the biological information acquisition clip 100. A conductive member 180 that covers a connection portion between the plate-like contact and the terminal portion 46 of the contact electrode 40 is disposed above the clip portion 110A.

  In the biological information acquiring clip 100A as the modification, the conductive member 180 projects from the upper surface portion of the first holding piece 122A onto the connecting portion 101A connecting the second holding piece 132A and the second holding piece 132A. Thus, it is integrally formed with the first sandwiching piece 122A. The upper surface of the conductive member 180 is covered with an insulating material similar to that of the first sandwiching member 120A.

  According to this configuration, when the second holding piece 132A moves in the separating direction with respect to the first holding piece 122A, the movement of the second holding piece 132A moves under the conductive member 180, and the clip portion Regardless of the open / closed state of 110A, it is in a state of being arranged on the clip portion 110A.

  As a result, the biological information acquiring clip 100A can obtain the same effects as the biological information acquiring clip 100. In the modification, the conductive member 180 disposed above the clip portion 110A that sandwiches the terminal portion 46 of the contact electrode 40 is provided integrally with the first sandwiching piece 122A of the clip portion 110A. Not limited to. In the configuration of the biological information acquisition clip 100A, the clip may be integrally formed on the second holding piece 132A so as to extend from the second holding piece 132A side to the upper side of the first holding piece 122A.

  Further, in the configuration of the biometric information acquisition clip 100A, in the clip portion 110A, the connecting portion 101A serving as a fulcrum for opening and closing the first holding piece 122 and the second holding piece 132 is connected to the first holding piece 122 and the second holding piece 132. An independent shaft portion may be used, and the conductive member 180 may be fixed to the shaft portion. In the case of this configuration, the conductive member 180 is fixed to the shaft portion so as to overhang the clip portion 110A having the first sandwiching piece 122A and the second sandwiching piece 132A. Thereby, the clip part 110A can be opened and closed under the conductive member and covered with the conductive member.

  Further, in the clip portion 110, a connecting portion serving as a fulcrum for opening and closing the first sandwiching piece 122 and the second sandwiching piece 132 is a shaft portion independent of the first sandwiching piece 122 and the second sandwiching piece 132, and the shaft portion includes It is good also as a structure which attached the electrically-conductive member 180 rotatably. In the biological information acquisition clip 100 configured as described above, when the contact electrode 40 is mounted, the conductive member 180 is rotated so that the connection portion with the terminal portion 46 by the plate-like contact is retracted from the upper position. it can. That is, in the biological information acquisition clip 100, the conductive member 180 can expose the connection portion between the clip portion 110 and the terminal portion 46. As a result, the plate-like contact is exposed upward, and the connection work can be performed while visually confirming the positional relationship between the plate-like contact and the terminal portion 46 of the contact electrode 40. Then, after the connection between the plate-like contact and the terminal portion 46 of the contact electrode 40, the conductive member 180 is rotated and positioned above the connection portion with the terminal portion 46 by the plate-like contact to cover these connection portions. Electrically shut off from the outside. Here, the conductive member is configured to be able to expose the position where the connection portion between the clip part 110 and the terminal part 46 is blocked by rotating, but is not limited thereto. The conductive member 180 that covers the connection portion with the terminal portion 46 by the plate-like contact, in other words, the connection portion between the clip portion 110 and the terminal portion 46 is attached to a position that covers the clip portion 110 above the clip portion 110 so as to be freely opened and closed. It is good also as a structure attached or foldable freely. Thereby, by opening / closing or folding the conductive member, the plate-like contact (clip part) and the terminal part are exposed upward, and the connection between them can be made while visually recognizing. After these connections, the conductive member is positioned at a position that covers the connection portion of the two (plate contact (clip portion) and terminal portion) above, thereby electrically connecting both the connection portion and the outside of the living body.
