Description

Detailed description of the invention

The present invention relates to accessories or wearable devices, in particular relating to such devices configured to be fitted and worn in the umbilical fossa. Here, the conceptual phenomenon of an accessory or a wearable device may be a mere decoration or a frightening purpose, or may be a built-in device equipped with an electronic device or the like for the purpose of measurement or communication.

Hereinafter, the concept of the present invention as described above will be illustrated with respect to the case of a wearable telemeter transmitter that collects and transmits a fetal signal (and, if necessary, a maternal signal as well) for the purpose of fetal monitoring. However, this example is merely an example for some purposes, and the gist of the present invention is not bound by the example of this particular embodiment.

In most cases of fetal monitoring these days, it is usual to mount a telemeter transmitter equipped with sensors on the abdominal wall of the mother and perform monitoring in an unrestrained state. However, this telemeter transmitter on the abdominal wall is usually mounted with a structure or configuration that can be fastened and tied up with a belt that orbits the body, and when worn, it "protrudes" from the abdominal wall. This bulge raises some problems, but it has traditionally been overlooked by the tacit understanding that "it is natural".

List some issues.
(1) If the sensor protrudes above the abdomen, it interferes with various other medical operations in the first place.
(2) When the sensor protrudes on the abdomen, friction occurs between the clothes, blankets, futons, etc. that are put on it, and mechanical noise due to so-called clothes rubbing (scratch) is generated, which is collected. It mixes directly or indirectly with the fetal signal or other biological signals that are produced, resulting in disturbing interference noise (artifacts).
(3) If the sensor protrudes on the abdomen, stress in the tangential direction is generated in synchronization with the above-mentioned rubbing of clothes, which may change the position and orientation of the sensor.

The present invention aims to realize a device configuration that can avoid such an unfavorable situation. That is, the wearable telemeter transmitter for fetal monitoring, which is designed and manufactured in a form embodying the gist of the present invention, is fitted into the umbilicus and is fitted, and as a result of being fitted, the back surface (opposite the body surface). The feature is that the surface facing the outside world) becomes "floating" with the surrounding abdominal wall so that it does not protrude.

Hereinafter, one of the typical and representative preferred examples will be described with reference to the illustration. FIG. 1 is a cross-sectional view of a wearable telemeter transmitter for fetal monitoring designed and manufactured in a form embodying the gist of the present invention according to the present invention, and as a whole, this device fits perfectly in the umbilical fossa. It is fitted and attached, and as a result of being attached, its back surface (the surface facing the outside world on the opposite side of the body surface) becomes "floating" with the surrounding abdominal wall, and it becomes a non-protruding state. It is configured as follows.

In this, the outer shell (1) of the device, which has a dome-shaped outer shape facing the umbilical fossa (2) side, forms a liquid chamber, and its wall is a hard (non-flexible) structure or a soft (flexible) structure. It is a structure, and its walls have the necessary strength but are sufficiently transparent for the ultrasonic waves used here. The liquid that fills this liquid chamber and allows ultrasonic waves to pass through well is selected from light water, heavy water, vegetable oil, animal oil, mineral oil, silicone oil, and the like. Although not shown, an ultrasonic wave transmitter / receiver having directivity by itself and an electronic device for supporting the ultrasonic wave transmitter / receiver for Doppler observation of fetal heartbeat are arranged in the liquid chamber. The electronic device has a function of transmitting a wireless telemeter as needed (or essential for making a closed structure), and a primary battery or a secondary battery is provided as a power source means. Gel or oil, water, higher alcohol, etc. for establishing an ultrasonic bond is interposed between the dome-shaped outer shell (1) and the skin of the umbilical fossa, and on the opposite side of the umbilical fossa. On the top plate facing the outside world, a large circular or rectangular adhesive plaster (4) is stretched between the skin (5) around the umbilicus and the presser plate (3). This holding plate (3) can be omitted, in which case the adhesive plaster (4) is directly stretched between the top plate of the dome-shaped outer shell and the skin (5) around the umbilicus. In the worn state, a step is generated from the skin (5) around the umbilical fossa by the amount of the holding plate and the adhesive plaster (for example, 2 to 3 mm), but the area of the step is a flat surface and is not a “bulge”.

However, since the device or function mounted in the liquid chamber is not related to the gist of the present invention and is included in the degree of freedom in carrying out the present invention, the details thereof cannot be explained one by one. ..

FIG. 2 is a bird's-eye view showing each part shown in FIG. 1 separated and disassembled on the central axis, and the numbers of the parts are the same as those in FIG. Here, as a practical point, the presser plate may be configured to be integrated with the present device in advance by adhesion or fitting, or may be omitted altogether.

In addition to the examples shown in FIGS. 1 and 2, the function or mounting content of this dome can be tailored to the observation of electrical phenomena using bioelectrodes, in which case the abdominal wall-guided fetal heart can be used for fetal monitoring. It is possible to obtain an electric signal, and it is also possible to observe external measurement labor pain based on a myoelectric signal as a side effect.

Furthermore, in addition to the examples shown in FIGS. 1 and 2, the function or mounting content of this dome can be tailored to observe mechanical or acoustic phenomena using a displacement meter, stress meter, accelerometer, or the like. In that case, it is possible to obtain a fetal heartbeat signal for fetal monitoring, and it is also possible to observe external labor pain based on the observation of hardness as a side effect.

Furthermore, in addition to the examples shown in FIGS. 1 and 2, the function or mounting content of this dome can be tailored to the observation of electrical phenomena using bioelectrodes, in which case the abdominal wall-guided foetation can be used for fetal monitoring. It is possible to obtain an electrocardiographic signal, and it is also possible to observe external labor pain based on the observation of a myoelectric signal as a side effect.

The specific means and methods for collecting each of the above possible signals are reasonably self-evident to experienced, expert and peers, and are not practical options outside the concept of the present invention. Since it belongs to the degree of freedom, it will not be explained in detail here.

On the other hand, the structure of the present invention can be used not for collecting signals but for radiating specific energies such as light, electromagnetic waves, and ultrasonic waves toward the outside world. The radiation can be for the purpose of markers, beacons, lights, decorations or scares. For example, by incorporating a light-emitting diode that emits intermittent light together with a battery and making the holding plate and adhesive tape for attachment transparent enough, an interesting animal with a shiny navel (including humans) can be simulated. In addition, if the function that the navel shines is used as a marker or beacon, a system will be constructed to be useful for automatic opening and closing doors, prevention of lost children, and discovery of people who have sunk in the sea, rivers, lakes, or swimming pools. You can do it. Such examples may also be preferred embodiments of the present invention.

The special fair 8-20500 is known for the purpose of finding a person who has sunk in the sea, river, lake or swimming pool, but even in that case, "where above each swimmer's neck" Since the "antenna for attaching to the crab and the transmitter that transmits the identification code" protrudes from the body surface, it can be the object of improvement by the implementation of the present invention.

The specific means and methods for the emission of each of the above possible energies are reasonably self-evident to experienced, intellectual and peers, and are not practical options outside the concept of the present invention. Since it belongs to the degree of freedom, it will not be explained in detail here.
