Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an electrode holder that holds an electrode and brings it into contact with the skin surface of a human body during recording of an electrocardiogram using an electrocardiograph.

(Prior Art) Conventionally, electrocardiogram recording electrodes are suctioned and held on the skin surface using suction cups separately for each measurement site of the human body (mainly the chest). However, with this suction cup method, if the negative pressure of the suction cup is weak, the suction force will be lost even if the patient moves slightly or sweats, so there are problems with the electrode holding power. Standard 12-lead electrocardiogram recording was becoming difficult. Furthermore, since adsorption requires pretreatment such as applying jelly to the skin surface to improve conductivity, it takes time and effort to set up the electrodes, which is extremely inconvenient especially in emergencies. In addition, the negative pressure of the suction cup sometimes caused subcutaneous bleeding in the patient's chest wall. On the other hand, a method of fixing the electrodes using adhesive tape has also been adopted, but in this case, the adhesive tape often causes redness of the skin, causing discomfort to the patient, and making the patient uncomfortable during long-term recording. There were many complaints.

[Purpose of the invention] Therefore, the present invention has excellent stability in the electrode holding state, enables electrocardiogram recording over long periods of time and during exercise, and allows for easy and quick electrode setting without the need for pretreatment such as applying jelly. The object of the present invention is to provide an electrode holder for electrocardiogram recording that can be used without causing subcutaneous bleeding or the like.

(Structure of the invention) The present invention comprises a front body and a back body, and the front body has a front-opening structure that can be opened and closed with an opening/closing device such as a fastener, and has an electrocardiogram recording electrode. The front body, into which is inserted and held, is made of a mesh fabric made of stretchable fiber threads and is stretchable.

With this configuration, the plurality of electrodes can be stably held in elastic contact with the human skin surface due to the elasticity of the front body. This makes it possible to record electrocardiograms for long periods of time and during exercise. In addition, there is no need for pre-treatment such as applying conductive jelly as with the suction cup type, and the electrodes can be set easily and quickly just like wearing a dust jacket, and there is a risk of subcutaneous bleeding, skin redness, etc. disappears.

(Example) An embodiment of the present invention will be described with reference to the drawings.

The electrocardiogram recording electrode holder 1 according to this embodiment is composed of a front body 2 and a back body 3, and the front body 2 is constructed in the shape of a front opening that can be opened and closed by a fastener 4.

The front body 2 of this holder 1 is formed of a highly stretchable mesh fabric made of stretchable fiber yarn such as spandex, and a plurality of electrodes 5 are inserted and held in the mesh of the front body 2. It's summery.

That is, as shown in FIG. 3, the electrode 5 includes a contact 51 that contacts the human skin surface A, a shallow-bottomed wire connector 52 to which the electrocardiogram recording wire 6 is connected, and this wire connector. A magnet 5 is interposed between the contactor 52 and the contact 51 to detachably connect the two.
It consists of 3. The contactor 51 includes a disk-shaped (or rectangular plate-shaped) contactor main body 51a, and this main body 5.
An attraction part 51b formed in the shape of a disk with a smaller diameter than 1a and attracted to the magnet 6 is integrally connected via a shaft-shaped part 51c, and the main body 51 is located inside the front body, and the attraction part 51b is attached to the attraction part 51b. is held at a position corresponding to each measurement part of the human body on the front body 2 in a state in which it protrudes to the outside of the front body, and in this state, the wire connector 52 is attracted to the attraction part 51b by the magnet 53 to form the electrode 5. . Note that the suction portion 51b is passed from the inside of the front body to the outside by elastically spreading the mesh by utilizing the elasticity of the mesh fabric.

In this case, in order to quickly and accurately set the electrodes 5 in each measuring part, the standard positions of each measuring part (electrode holding device) are pre-marked in circles on the front body 2, as shown in FIG. It is indicated by mark m...

On the other hand, the rear body 3 of the holder 1 is made of a relatively strong fabric such as jersey, and is sewn to the front body and both sides in order to maintain the strength of the entire holder.

When using this electrode holder 1, place the required number of electrodes 5 on the front body 2 as described above, following the markings of the circles m pre-provided on the front body 2 as standard electrode setting positions. With the main body 51a of the contactor 51 positioned on the inside and the wire connector 52 on the outside, the contactor 51 is attached to the upper body in the same way as wearing a zipper, and the fastener 4 is closed. Alternatively, the electrodes 5 may be set before the fastener 4 is closed after being worn on the upper body. In addition, before or after closing the fastener 4, the patient's physique,
The set position of the electrode 5 is adjusted according to the body shape.

In this worn state, the electrodes 5 are stably held in a state in which the contact body 51a is elastically pressed against the human skin surface A due to the elasticity of the front body 2 and in close contact with it, as shown in FIG. In addition, when worn, the front body 2 is always kept in close contact with the skin surface A by following the movements of the human body and muscles due to its elasticity, so that the contact state of the electrodes 5 with the skin surface A is maintained. Reliably held. Therefore, unlike the conventional suction cup method, there is no risk of the electrode coming off the skin surface or causing poor contact due to slight movements of the human body, sweating, etc. For this reason, standard 1 during long periods of exercise and electric transmission, which was difficult in the past.
2-lead electrocardiogram recording becomes possible.

By the way, the contact 51 of the electrode 5 and the wire connector 52 may be detachably connected by screw connection. Further, in order to further enhance the stretchability of the entire holder, the back body 3 may also be formed of a mesh fabric made of stretchable fiber yarn. Furthermore, buttons, tape fasteners, etc. may be used as opening/closing devices for the front body.

(Effect of the invention) As described above, when using the electrocardiogram recording holder of the present invention, it is worn on the upper body like wearing a chiyotsuki, and the electrodes inserted through the front body are attached to the human skin surface due to the elasticity of the front body. Because the electrodes are held in close contact with each other, unlike conventional suction cup types, there is no risk of the electrodes coming off due to slight movement or sweating, and the electrodes are held in a much more stable state. Become something. This makes it possible to record standard 12-lead electrocardiograms for long periods of time and during exercise, which has been difficult in the past. In addition, there is no need for pretreatment such as applying conductive jelly as in the case of the suction cup type, and the electrodes can be set easily and quickly, making it extremely convenient for recording electrocardiograms, especially in emergencies.
Furthermore, there is no risk of subcutaneous bleeding as in the case of the suction cup type or redness of the skin as in the case of the adhesive tape fixation type. Furthermore, electrocardiogram recording can be easily performed on patients who have lost part of their limbs due to trauma.
