Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables an electrode to be closely attached to a predetermined position on the body of a patient when the electrode is fixed to the body of the patient for recording an electrocardiogram by putting the electrode on the patient. In particular, the present invention relates to a retractable electrode structure for such a clothing accessory.

[0002]

2. Description of the Related Art As is well known, conventionally, in order to record an electrocardiogram, a method of sticking individual electrodes to the body of a patient with adhesive tape in correspondence with the position of inducing electromotive force of the heart is adopted. Has been done.

Incidentally, among cardiac diseases, angina pectoris, myocardial infarction, arrhythmia and the like cause changes in the electrocardiogram only when symptoms occur, and therefore recording the electrocardiogram at that time is indispensable for confirming the diagnosis. However, in these diseases, changes in the electrocardiogram are transient, and it is often difficult to induce seizure even in a provocation test at the time of examination, and it often takes time to confirm the initial diagnosis.

For this reason, in order to record an electrocardiogram when a symptom appears, care must be taken so that the electrocardiogram can be recorded on the spot at the time of an attack in daily life.
A time electrocardiography test has been performed.

[0005]

According to the conventional 24-hour electrocardiogram recording and inspection method, as a matter of course, if no seizure occurs within 24 hours while the patient is wearing the recorder, 2
The 4-hour record itself becomes meaningless. The recording time can be extended by replacing the recording tape, etc., but in the case of 24-hour electrocardiogram or ECG monitoring in a ward, the electrode is conventionally attached to the patient's body with adhesive tape, so the skin There is a risk of rash or itching, which causes great pain to the patient. Further, in a long-time recording inspection, the work is difficult because the adhesive tape is peeled off due to sweat or dirt. On the other hand, in the case of recording an electrocardiogram in an electrocardiographic examination room, it is a method of sandwiching a large clip-type electrode on a limb or adsorbing a sucker-type electrode on the chest so that the purpose of the invention is to continuously monitor it. Needless to say, it is not suitable for electrocardiographic examination. Furthermore, since the recording itself only makes two or three simple bipolar leads, there are many unsuitable points, such as a decrease in objectivity for ST segment analysis, which is important for the diagnosis of angina.

[0006]

As a result of various studies, the present inventor has found that, in order to solve the above problems, an electrode is attached to a sheet-shaped clothing accessory such as underwear, and a patient wears such clothing. Wearing a tool and spending the time until a seizure is significantly easier than the conventional method of sticking electrodes with adhesive tape or sandwiching them with clips, and especially 12-lead We have found that there is a special effect in waiting for the continuous recording of the electrocardiogram, and the patient's pain is greatly reduced, which is advantageous. However, in constructing such a clothing accessory, it is necessary to consider the following conditions.

First, according to the experience of the present inventor, it is expected that some patients will have only a few strokes per month, and that a record examination for a considerably long period of time will sometimes have to be performed. Therefore, it is necessary for the clothing accessory to minimize the burden on the patient when wearing the clothing, and it is required not to press the body during the waiting period before the attack or to cause a feeling of strangeness. In particular, in the configuration in which the electrode is provided inside the clothing, the electrode compresses the wearer's skin during wearing,
It is necessary to take care not to scratch the skin, and if the electrode gel, adhesive or metal is in contact with the skin for a long period of time, it may cause allergic contact dermatitis. You have to be careful.

Second, at the time of an attack, the relationship between the electrodes and the body must be maintained in a state that enables quick and good recording.

Thirdly, it should be easy to put on and take off the body in consideration of taking off the clothing accessories when taking a bath.

Therefore, the present inventor has found that the patient can wear the garment in a relaxed manner while waiting, and the electrodes do not press or scratch the skin of the patient, while a seizure or the like suddenly occurs, and an electrocardiogram is obtained. We have found that it is advantageous to configure the electrode so that it can be brought into close contact with the target site on the body surface quickly when recording must be performed. The present invention can be achieved by arranging the electrodes so that they can be projected and retracted, and the electrodes are made to stick out and be brought into close contact with the body when necessary.

Thus, the present invention constitutes the first means.
Do not touch the position where the electromotive force of the heart is induced when worn.
In a sheet-shaped clothing accessory that has an electrode
The sheet-shaped part corresponding to the pole has a concave opening on the inner surface of the clothing accessory.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In the overall structure shown in FIGS. 1 and 2, 1
As shown in FIG. 1, the garment 1 shown as an example includes a band body 2 having a front body 2a, and a pair of band shoulders 3 and 3 extending upward from the center of the front surface of the band body. It is formed into a sheet-like thing provided with. Such a clothing accessory 1 can be manufactured by cutting a woven fabric, a knitted fabric, a synthetic leather or the like and sewing it, or a synthetic resin film or the like and cutting and welding the material. By incorporating a knitted fabric that is wholly or partially stretchable, the wearing feeling can be made good.

The band body portion 2 is detachably and detachably formed corresponding to a flank portion of a wearer (patient, the same applies hereinafter), and has a fastener 4 for this detachment. The strap shoulders 3, 3 are configured to be detachable from the rear portion of the strap body 2 via both shoulders of the wearer, and have fasteners 5 for this detachment. As these fasteners 4, 5, hooks, buttons, hook-and-loop fasteners, zippers, and the like can be appropriately used.

A plurality of electrodes 6 are provided on the inside of the clothing accessory 1 so as to correspond to the positions for inducing electromotive force of the heart of the wearer when the wearer wears it. In the example shown, it has electrodes 6a-6j arranged according to a monopolar chest lead. Lead wires extending from these electrodes 6 are wired through the inside of the clothing accessory 1 and are connected to a connector 7 provided outside the clothing accessory 1, and are detachably inserted into the connector 7 via a multiaxial pin. Plugs worn 8
Therefore, it is preferable to have a structure in which the cable is guided to the electrocardiogram through the cable 9.

As shown in FIG. 2A, the electrode 6 is
The recessed portion 10 is attached to the bottom of the recessed portion 10 formed by the corresponding sheet-shaped portion of the clothing accessory 1 and opening to the inner surface of the clothing accessory 1, so that the electrode 6 does not normally protrude from the opening of the recessed portion 10. It is buried inside. As will be described later , such a recessed portion 10 is constituted by a grooved gather formed by bending a sheet-shaped member constituting the clothing accessory 1 in a wave shape, or is formed in a spot-like shape on the sheet-shaped member. It can be constituted by a cup-shaped pocket formed.

[0019] The recess 10 is normally is kept recessed shape, is when tightened Chakumigu 1 by fastening means 11 to be described later extending transversely of the recessed portion 10 by the tension of the sheet-like member It is configured to deform the recessed portion 10 into a flat state or a nearly flat state. Alternatively, the pressing means 16 described later
Flatten while pressing the recessed part 10 pressed from the side
It is configured to be transformed into a close state .

( Structure of tightening means ) In the embodiment shown in FIGS. 1 and 2, tightening means 11 is provided to allow the clothing 1 to be tightened so that the recess 10 can be expanded and contracted. In the case of the illustrated example, the tightening means 11 is a single or a plurality of balloon portions 12 formed on the whole or a part of the clothing accessory 1, and a fluid supplying means for supplying a fluid to the balloon portions 12 to inflate the balloon portion 12 (FIG. (Not shown). Such a balloon portion 12 is used for the clothing accessory 1.
When it is formed of a synthetic resin film, it can be easily formed by forming the synthetic resin film into an inner and outer double structure and closing the inner and outer films in a bag shape by high frequency welding or the like. On the other hand, when the clothing accessory 1 is made of a woven or knitted fabric, a separate balloon member made of rubber or synthetic resin elastomer may be attached to the clothing accessory 1.

The fluid supply means (not shown) can be easily realized by using an electric or manual air pump or an air cylinder capable of ejecting compressed air. At this time, as the substance for inflating the balloon portion 12, liquid other than gas such as air and gas can be freely used, and any liquid can be used.

In the illustrated example, in order to conveniently connect the fluid supply means and the balloon portion 12, the inlet tube 13 extending from the balloon portion 12 and the supply tube 14 extending from the fluid supply means are connected by a detachable joint 15. is doing.

Although FIG. 1 shows the embodiment of the garment 1 having the best shape, the shape of the garment 1 is not limited to this, and any design is possible.

In the illustrated embodiment, as shown in FIG.
The electrode 6 is arranged on the front part F of the wearer, and the balloon part 12
Is provided on the back R of the wearer. Then, in the normal wearing state shown in FIG. 2 (A), the clothing accessory 1 has a certain amount of room or allowance with respect to the body, and the size is set so that the wearer can relax without pressing the body. There is. Further, in this state, the electrode 6 is buried in the recess 10 and does not press the wearer's skin.

Therefore, when the wearer has a seizure,
When the symptom is observed, the fluid supply means is actuated to start the fluid supply, and as shown in FIG.
Inflate 2 That is, when the fluid supply means is the above-mentioned air pump, the pump is operated, and when the fluid supply means is the above-mentioned air cylinder, the valve of the cylinder is opened to inflate the balloon portion 12 in a short time. . By expanding the balloon portion 12 in this way,
As shown by an arrow T in FIG. 2B, the clothing accessory 1 is strained toward the back R of the wearer. As a result, the front body 2a of the clothing accessory 1 receives tension and expands, deforming the recessed portion 10 into a flat or near-flat state, so that the electrode 6 is brought into close contact with the body as indicated by the arrow P. This makes it possible to record an accurate electrocardiogram with the electrode 6 firmly attached to a predetermined position on the body.

As described above, in the embodiment based on the tightening means 11 , the tightening means 11 constituted by the balloon portion 12 extends the recessed portion 10 in the transverse direction, and as a result, the electrode 6 is attached to the inner surface of the garment 1. The basic structure is to make it more prominent. Incidentally, when the recessed portion 10 is composed of grooved gathers, the gathers are arranged symmetrically with respect to the front center line of the wearer so that all the gathers can be equally extended by the tightening means 11. It is preferable to keep. In other words, gathers without the electrodes 6 may be provided for this purpose.

By the way, when the joint 15 is separated or the exhaust port (not shown) of the balloon portion 12 is opened to discharge the fluid in the balloon portion 12 and to deflate the balloon portion 12, the concave portion is depressed. The portion 10 is restored to the concave shape again, and thereafter, the same operation as described above can be repeated. Therefore, when the sheet-shaped member of the clothing accessory 1 including the recessed portion 10 is formed of a knitted fabric, the restoring means is configured by braiding an elastic yarn such as a rubber yarn so as to allow the extension and the restoration. It is preferable to keep. On the other hand, the concave portion 1
When the sheet-shaped member of the clothing accessory including 0 is formed of a synthetic resin film or the like, the restoring means is configured by lining an elastic sheet such as a rubber sheet that holds the concave shape in the bent portion of the concave portion 10. It is preferable to set.

( Structure of Pressing Means ) In addition to the tightening means 11 as described above , the retracting means for the electrode 6 which is the object of the present invention is to push the recessed portion 10 from the outside so that the electrode 6 of the dressing tool 1 is pressed. It can be constituted by a pressing means 16 for making it protrude from the inner surface.
