Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a housing jacket for a biological signal recording device, and particularly to a portable biological signal recording device that can be used for long periods of time.

[Conventional technology]

Conventionally, when a subject carries a portable long-term recording device for biological signals such as a Holter electrocardiograph (for example, the electrocardiogram recording device 21), it is stored in a dedicated storage case as shown in Figure 9 and carried over the shoulder. The first method is to hang it from the waist as shown in Figure 10, the second method is to hang it from the waist as shown in Figure 10, and the second method is to hang it from the waist as shown in Figure 11. A third method in which the device is supported by a person's body, and a fourth method in which the device is stored in a portable bag and carried around without being attached to the human body.

[Problem to be solved by the invention]

The conventional method described above has the following problems.

In the first method, the device to be carried weighs about 300g to Ikg and is hung on one shoulder, so if it is carried for a long time, the weight will be transferred to the shoulder of the elderly or children.

This was a heavy burden on the sickly subjects.

Moreover, the burden caused mental pain and had the possibility of worsening the patient's medical condition. Because the device is hung on one's shoulder, there is a possibility that when exercising during daily life, the device may vibrate, resulting in deterioration of signal quality, or damage to the device due to contact with other objects. Ta.

Compared to the first method, the second method puts less stress on the subject and causes less vibration on the device, but it does not solve problems such as damage to the device due to contact with other objects. In addition, this method has the disadvantage that if the waist belt is not tightened tightly, it will gradually fall off due to the weight of the device, and if it is too tightened, it will interfere with daily life, so it is not suitable for obese people. was difficult.

The third method is a method that compensates for the shortcomings of the first and second methods, and it solves the drawbacks such as vibration, but for the subject wearing it, it is fixed at two points: the shoulder and the waist. However, there were problems in that the user felt strongly uncomfortable due to the feeling of restraint, and the device could not be easily removed.

The fourth method does not cause a feeling of restraint or discomfort compared to the first to third methods, but it requires the subject to carry a portable bag with him wherever he goes during daily activities, and the subject always has to be conscious of carrying the bag. The complexity that must be maintained,
In the unlikely event that you forget your bag, the signal input cable is fixed to the human body, so the bow may be stretched, causing problems with the cable or the equipment's node wear, or causing problems with data loss due to electrodes coming off. had.

Furthermore, a common problem with methods 1 to 4 is that the electrodes are attached to the surface of the body; from there, a signal cable is passed through clothing to send signals to a device attached to the clothing, so the cables are exposed. In some cases, the electrodes may not be properly attached by pulling on them, and the device must be removed from the storage compartment when going to bed or changing clothes, which can lead to problems such as data loss due to poor electrodes, etc. It had a point.

On the other hand, with recent advances in microprocessors, microprocessors are being incorporated into devices that previously only had a tape recorder recording function, increasing the weight and size of the devices. Separate types of devices have also appeared.

In order to cope with such weight, size, and separation type, the first to fourth methods had the problems described above, and actually imposed a heavy burden on the test subject.

[Means to solve the problem]

The biosignal recording device storage jacket of the present invention is pre-equipped with at least one pocket for storing the biosignal recording device, and an air bag that can control internal pressure and is placed facing the sensor that acquires the biosignal. The device is constructed with two strings, one end of which is fixed, and the other end of which is pulled and tied together in accordance with the wearer's body.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an external view showing the configuration of an embodiment of the present invention.
FIG. 2 is an external view showing the state in which this embodiment is worn on a human body.

In Figure 1, the overall shape is in the form of a life jacket or a pesto, and the arm is passed through the sleeve hole 4, worn directly on the body or over underwear, and the string 5 is tightened.
Therefore, it fits your body.

Reference numerals 1 to 3 are pockets that house biological signal recording devices and the like. If there is only one device to be worn, it is stored in one of the pockets, from which the signal input cable 6 connected to the sensor 7 for acquiring biological signals comes out.

For example, when recording electrocardiograms for a long period of time, such as with a Holter electrocardiograph, as shown in Figure 3, the electrocardiogram electrode 2 is used as a sensor.
2 is attached to the chest wall of the human body. The lead wires from the electrocardiogram electrodes are collected and guided to the electrocardiogram recording device 21 through the signal input cable 23.

In addition, when carrying multiple devices, for example, when attaching a real-time analysis device such as a Holter electrocardiograph and a magnetic tape recording device, each device can be connected to the connector 9 of the cable 8 as shown in Figure 1. Connected.

Next, the most important thing when acquiring biological signals over a long period of time is to stably obtain high-quality biological signals.

In this embodiment, these are realized by the following means. First, in order to obtain a stable signal, the jacket 111 shown in FIG. 1 needs to fit snugly to the body. For this purpose, as shown in FIGS. 5 and 6, the fitting string 5 shown in FIG. 1 is stretched over the jacket so that the entire jacket fits the body. The laces 41 in FIGS. 5 and 6 have a folding ring 42, at which each lace is folded back towards the side of the body. There is a guide 43 for this purpose on the side of the body. FIG. 6 is a view of the string path viewed from the body surface, and the string 41 from the back is fixed by the string fixing part 44. Furthermore, there is a guide 43 that brings the front string to the back of the body. The strings shown in FIGS. 5 and 6 do not necessarily come out on the surface of the jacket, but it is sufficient if a guide path such as sewing along the path of the strings is inserted into the jacket in advance.

In addition, to prevent devices stored in each pocket from accidentally popping out, the openings of the pockets are made of flexible material.
Keep it at 0.

In this way, the device and the jacket are firmly fixed, but on the other hand it is also necessary to fix the biosignal input sensor (electrode). In this embodiment, as shown in FIG. 4, an air mat 31 is attached to the back side of the jacket at a portion corresponding to the position where the electrodes are to be attached. In addition, a pump 32 for injecting air into the air mattress 31 is placed at a location convenient for operation, slightly away from the air mattress 31. Therefore, as shown in FIG. 7, the biological signal input electrode attached to the body surface 51 is firmly pressed down by the air mat 53 into which air is injected, and will not come off even if there is some body movement. By making the entire jacket out of a suitably stretchable fabric by injecting air, it is possible to fit the jacket regardless of body shape.

Furthermore, in order to further enhance the effects of this embodiment, the material on the back of the biosignal input electrode 52 worn on the body is also made of a flexible fastener, and the fabric of the air mat 53 is also made of a flexible fastener to ensure close contact between the electrode and the air mat part. This further improves the properties of the electrode and prevents incomplete electrode holding due to air bias υ, etc.

〔Effect of the invention〕

As explained above, the present invention has the following effects compared to the conventional system.

(1) Compared to attaching a device to the shoulders or waist, the weight on the body is dispersed and the burden is reduced.

This makes it easier for elderly, infirm patients, children, etc. to attach the device.

(2) The present invention is not attached to clothes as in the past, but is attached to the body surface or underwear, so clothes can be attached over it, and it is visible from the outside that the device is attached. Since there is no screen, you can wear it without any hesitation to obtain information about your daily life.

(3) Conventionally, when sleeping, the electrode was removed from the body and placed on the bedside, but with the present invention, it is possible to sleep with it attached to the body, which eliminates the complication and eliminates the possibility of the electrode coming off when removed from the body. , accidents such as cable breakage can be prevented.

(4) Since it can fit around the waist of the body, better quality signals can be obtained compared to conventional methods, and there is no loss of biological information due to electrode detachment, etc.

(5) In the conventional method, the signal input cable was placed over the clothes, so the signal input cable was inserted from outside under the clothes, but with this method, it is not exposed, which prevents disconnection accidents due to contact with the cable and noise contamination.

(6) This method uses shrinkable fabric, air mats, and other methods to fit the device regardless of body size or shape, so it has the advantage that anyone can wear it compared to conventional methods.
