Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention provides a method for fixing electrodes on a patient's body to record an electrocardiogram, by making the electrodes wear on the patient so that the electrodes can be placed closely at a predetermined position on the patient's body. Concerning personal accessories.

0002

[Prior Art] As is well known, in order to record an electrocardiogram, a method has traditionally been adopted in which individual electrodes are attached to the patient's body using adhesive tape, corresponding to the position where the electromotive force of the heart is induced. has been done.

Incidentally, among heart diseases such as angina pectoris, myocardial infarction, and arrhythmia, electrocardiogram changes occur only when the symptoms occur, so it is essential to record the electrocardiogram at that time to confirm the diagnosis. However, in these diseases, changes in the electrocardiogram are often transient, and it is often difficult to induce seizures even during provocation tests at the time of medical examination, so it often takes time to confirm the initial diagnosis.

[0004] Therefore, in order to record an electrocardiogram at the time of onset of symptoms, consideration must be given to being able to record an electrocardiogram on the spot during an attack in daily life.
Time electrocardiogram recording tests have been performed.

[0005]

[Problems to be Solved by the Invention] In the conventional 24-hour electrocardiogram recording test method, if a patient does not have a seizure during the 24-hour period in which the recorder is worn, the
The 4-hour record itself becomes meaningless. It is possible to extend the recording time by replacing the recording tape, but in the case of 24-hour ECG monitoring or ECG monitoring in hospital wards, the conventional method is to attach electrodes to the patient's body with adhesive tape, which requires close contact with the patient's skin. There is a risk of rash and itching, which causes great pain to the patient. Furthermore, during long recording inspections, the adhesive tape peels off due to sweat and grime, making the work difficult. On the other hand, in the case of electrocardiogram recording in electrocardiogram laboratories, conventional methods involve attaching large clip-type electrodes to the hands and feet, or attaching suction cup-type electrodes to the chest. Needless to say, it is not suitable for electrocardiogram recording tests. Furthermore, since the recording itself consisted of only two or three simple bipolar leads, it had many disadvantages such as decreased objectivity for ST segment analysis, which is important for diagnosing angina pectoris.

[0006]

[Means for Solving the Problems] As a result of various studies, the present inventors have found that in order to solve the above problems, electrodes are attached to sheet-like personal items such as underwear, and patients wear such clothing. If you wear the device and spend the time before having a seizure, it is much easier to work with than the conventional methods of attaching electrodes with adhesive tape or clipping them together. It has been found that this method has a special effect when waiting for continuous electrocardiogram recording, and is advantageous because it greatly reduces patient's pain. However, when constructing such a personal accessory, it is necessary to consider the following conditions.

First, according to the experience of the present inventor, some patients have only two or three seizures per month, and it is expected that recording examinations may sometimes have to be carried out over a considerable period of time. Therefore, it is necessary for the personal clothing to minimize the burden on the patient when wearing it, and it is required that it does not put pressure on the patient's body or cause discomfort while waiting for an attack.

[0008] Second, when a seizure occurs, the relationship between the electrodes and the body must be in a state that allows for rapid and good recording.

Thirdly, it must be easy to put on and take off the body, taking into account the need to take it off when taking a bath or the like.

[0010] Therefore, the inventor of the present invention has proposed that while a patient can comfortably wear personal clothing while waiting, when a seizure or the like occurs and an electrocardiogram must be recorded in a hurry, the electrodes can be quickly moved to the intended purpose on the body surface. The present invention has been achieved by realizing that it is advantageous to configure the clothing so that it can be closely attached to the body part, and by changing the state of the clothing by using a balloon part that is inflated through supply of fluid. It was made.

[0011] The present invention is characterized by a sheet-like personal accessory provided with electrodes corresponding to positions where electromotive force of the heart is induced when worn. The present invention comprises a balloon portion formed by at least a portion of the clothing item in order to bring the portion into close contact with the body, and a fluid supply means for inflating the balloon portion.

[0012] In order to achieve the above-mentioned object, the balloon portion may be formed at a position apart from the electrode, and constitute a tightening means for tightening the personal item to the body by inflating the balloon portion.

Alternatively, the balloon portion may be formed so as to be located on the electrode, and constitute a pressing means that presses the electrode against the body by inflating the balloon portion, whereby the above-mentioned object can also be achieved. .

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described in detail below with reference to the drawings.

(Overall configuration of personal accessory) FIG. 1 shows personal accessory 1.
The garment 1 includes a belt body part 2 having a front body part 2a, and a pair of belt shoulder parts 3, 3 extending upward from the front center of the belt body part. It is formed into a sheet shape. Such clothing items 1 can be manufactured by cutting and sewing woven fabrics, knitted fabrics, synthetic leather, etc., or by cutting and welding synthetic resin films, etc., and the material is not limited. By incorporating a stretchable knitted fabric in whole or in part, it is possible to improve the wearing feeling.

[0016] The belt body portion 2 is separated from the side of the wearer (patient, the same applies hereinafter) and is configured to be detachable, and has a fastener 4 for detachable attachment. The belt shoulder parts 3, 3 are configured to be detachable from the rear part of the belt body part 2 through both shoulders of the wearer, and have a fastener 5 for this purpose. These fasteners 4 and 5 are hooks,
Appropriate materials such as buttons, hook-and-loop fasteners, and zippers can be used.

A plurality of electrodes 6 are provided on the inside of the garment 1, corresponding to positions where electromotive force of the wearer's heart is induced when the garment is worn. The illustrated example has electrodes 6a-6j arranged according to a monopolar thoracic lead. The lead wires extending from these electrodes 6 are routed through the inside of the garment 1, connected to a connector 7 provided on the outside of the garment 1, and detachably inserted into the connector 7 via a multi-axis pin. Plug 8 to be attached
It is preferable that the electrocardiogram is guided through the cable 9 to the electrocardiogram.

A balloon portion 10 is formed on the entire or part of the garment 1, and the balloon portion 10 is inflatable with fluid from a fluid supply means (not shown). When the personal item 1 is made of a synthetic resin film, such a balloon part 10 can be formed by forming the synthetic resin film into a dual structure of inside and outside, and closing the inside and outside films into a bag shape by high frequency welding or the like. It can be easily formed by On the other hand, if the personal item 1 is made of woven or knitted fabric, a separate balloon member made of rubber or synthetic resin elastomer may be attached to the personal item 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 blowing out compressed air. At this time, as the substance for inflating the balloon portion 10, in addition to air or gas, a liquid may be used, and any fluid may be used.

In the illustrated example, in order to conveniently connect the fluid supply means and the balloon part 10, an inlet tube 11 extending from the balloon part 10 and a supply tube 12 extending from the fluid supply means are connected by a detachable joint 13. are doing.

Although FIG. 1 shows an embodiment of the vest-shaped personal item 1, the shape of the personal item 1 is not limited to this, and can be designed as desired.

(First Embodiment) FIG. 2 shows a first embodiment regarding the configuration of the balloon section 10. In this first embodiment, the electrode 6 is placed on the front F of the wearer, and the balloon part 10 is placed on the back R of the wearer.

In the normal wearing state shown in FIG. 2(A), the clothing item 1 has a certain amount of room or room for the wearer's body, and the size is set so that the wearer can relax without putting pressure on his or her body. It has been done.

[0024] Therefore, when the wearer has a seizure, etc.
When symptoms appear, the fluid supply means is activated to start fluid supply, and the balloon part 1 is removed as shown in FIG. 2(B).
Expand 0. 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, so that the balloon portion 10 is inflated in a short time. . By expanding the balloon part 10 in this way,
As shown by the arrow T in FIG. 2(B), the clothing accessory 1 is stretched toward the back R of the wearer. As a result, the front body 2a of the garment 1 is tightened to the front F of the wearer, and the electrode 6 is brought into close contact with the wearer's body as indicated by the arrow P. This makes it possible to record an accurate electrocardiogram while keeping the electrode 6 firmly in close contact with a predetermined position on the body.

[0025] Thus, in this first embodiment,
The balloon portion 10 constitutes a tightening means for tightening the clothing item 1 to the body.

(Second Embodiment) FIG. 3 shows a second embodiment regarding the configuration of the balloon section 10. In this second embodiment, a plurality of balloon parts 10a, 10b are provided. One balloon part 10a is located on the back R of the wearer as in the first embodiment, and the other balloon part 10b is located on the front F of the wearer and outside the electrode 6. It is located at.

[0027] The pair of front and rear balloon parts 10a and 10b are as follows:
Parallel supply paths 12a and 12b communicated with each other are connected to fluid supply means S via a switching valve 12c. In the normal wearing state shown in FIG. 3(A), the personal accessory 1
As in the case of the first embodiment described above, there is a certain amount of room for the body.

Therefore, when the wearer shows symptoms, when the fluid supply from the fluid supply means S is started, the balloon part 10a on the back is inflated first, and then the balloon 10b on the front part is inflated. . That is, the balloon parts 10a and 10b are inflated under such a time difference. As a result, not only can the electrode 6 be indirectly brought into close contact with the body by tightening the clothing 1 to the body as in the first embodiment, but also the electrode 6 can be brought directly into contact with the body by the front balloon portion 10b. Since the electrode 6 can be brought into pressure contact with the wearer's body, even if the wearer's body surface is uneven, the electrode 6 will not float away from the wearer's body surface and can be reliably brought into pressure contact with the wearer's body surface.

The configuration of the switching valve 12c that allows the inflation time difference is such that when the fluid is supplied to one of the supply channels 12a, when the back balloon portion 10a is inflated to a constant pressure, the pressure is It is possible to employ a pressure-sensing valve that detects and switches the supply of fluid not only to one supply path 12a but also to the other supply path 12b. Alternatively, a timer type valve may be used that starts counting when fluid is supplied to one of the supply channels 12a and switches the flow channel to communicate with both supply channels 12a and 12b after a predetermined period of time has elapsed.

[0030] Thus, in this second embodiment,
The balloon portion 10a on the back constitutes a tightening means similar to the first embodiment, while the balloon portion 10b on the front constitutes the electrode 6.
It constitutes a pressing means for pressing the body against the body.

(Third Embodiment) In the third embodiment shown in FIG. 4, the clothing accessory 1 includes band members 13a and 13b extending long from both sides of the band trunk 2 constituting the front body 2a. Balloon portions 10c and 10d are provided near the ends of both band members 13a and 13b, respectively. Although not shown, a plurality of electrodes are attached to the inside of the front body 2a corresponding to predetermined positions on the body.

[0032] This clothing accessory 1 has a pair of band members 13a, 13 which are attached from the front body 2a to the front of the wearer's body.
After crossing b at the back of the body, wrap both sides of the band 13a and 13b.
further wrap around the body and cross them at the front of the body, position the respective balloon parts 10c and 10d on the left and right flanks of the body, and in this state position the fasteners 14 of each band body 13a and 13b on the lower side. It is detachably fixed to corresponding parts of the band members 13a and 13b.

Therefore, when the pair of balloon parts 10c and 10d are inflated by the fluid supplied from the fluid supply means (not shown), the tension caused by this expansion causes the pair of windings to be Band body 13a,
13b is pulled and tightened onto the wearer's body, thereby bringing the front body 2a into close contact with the front of the body and bringing the electrodes into pressure contact with the body surface. At this time, the pair of band members 13a, 13b
It is preferable to consider that the coefficient of friction is as small as possible at each intersection of the band members 13a and 13b.
It is desirable to select the material from fabrics with smooth surfaces such as synthetic resin films and synthetic leather. Alternatively, the band body is divided at a portion corresponding to the intersection, and the divided ends are connected by a plurality of parallel strings of a predetermined length, and the strings overlap vertically to form the intersection. It may be configured as follows.

[0034] Thus, the pair of balloon parts 10c and 10d in this third embodiment constitute a tightening means for tightening the garment 1 to the body.

(Another Embodiment) As mentioned above, the balloon portion of the present invention can be configured as a means for tightening the personal clothing 1, or as a pressing means for directly pressing the electrode 6 against the body. The clothing accessory 1 has two functions, and one of the functions can be selected and provided on the clothing accessory 1. That is, as described above, in the first and third embodiments shown in FIGS. 2 and 4, the balloon portions 10, 10c, and 10d constitute the tightening means. On the other hand, in the second embodiment shown in FIG. 3, two balloon parts 10a and 10b are used together, which constitute a tightening means and a pressing means, respectively.

By the way, although not shown in the drawings, the present invention
It is also possible to provide only the balloon portion that constitutes the pressing means alone, and thereby it is also possible to achieve the intended purpose. That is, in the configuration shown in FIG. 3, only the balloon part 10b constituting the pressing means is provided, and only the balloon part 10b is inflated by the fluid provided by the fluid supply means S, thereby bringing the electrode 6 into pressure contact with the wearer's body. It may also be used as a configuration.
