Description

{MEASURING DEVICE FOR PHYSICAL INFORMATION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body information measuring apparatus, and more particularly, to a body information measuring apparatus capable of measuring respiration and body fluid of a subject during sleep.

As interest in health increases, the use of devices that provide various kinds of physical information is increasing. For example, in the case of a smart watch, body information such as a wearer's heart rate, momentum, and body temperature is measured and provided to the wearer. In addition to smart watches, devices for measuring body information are also provided in garments, helmets, belts, and the like, and such devices are wearable devices worn by the user.

The wearable device may be uncomfortable because it must be in contact with the user's body. Therefore, there is an increasing need to develop a device capable of measuring body information without directly contacting the user.

In recent years, the development of sensor technology has enabled measurement of the health status of the subject by measuring the gas generated from the respiration of the body. However, the method of measuring gas after coming into contact with the mouth or nose of the subject by using a device such as a mask, etc., causes gas generated in the respiration of the body to cause inconvenience to the user and discomfort.

1 and 2 are a perspective view and a side view, respectively, illustrating states in which a body information measuring apparatus 100 according to an embodiment of the present invention is installed on a bed. FIG. 3 is a plan view illustrating the body information measuring apparatus 100 illustrated in FIG. 1, and FIG. 4 is a sectional view illustrating a body gas detecting sensor unit 120 in the body information measuring apparatus 100 illustrated in FIG. to be.

1 to 4, a body-information measuring apparatus 100 according to an embodiment of the present invention includes a body-of-information measuring apparatus 100 installed on a bed, for detecting living body gas and body fluids generated from a subject 170 during a sleep of a subject 170 And analyze it. The body information measuring apparatus 100 includes a body gas detecting sensor unit 120 for measuring the living body gas of the subject 170 and a body fluid detecting sensor unit 112 for detecting the body fluid of the subject 170.

Although the body information measuring apparatus 100 according to the present embodiment is illustrated as being installed in a bed, the body information measuring apparatus according to the present invention is not limited in its installation place. Therefore, the body information measuring apparatus according to the present invention can be installed in a sofa, a massage chair, a crib bed, a desk, or the like.

The bed on which the body information measuring apparatus 100 is installed includes a frame 102, a support 104 for supporting the frame 102 at a predetermined height from the ground and a mattress 110 located on the frame 102 . An upper plate 108 protruding upward is provided at one end of the frame 102. The examinee can lie down on the mattress 110 to take sleep.

The living body gas detection sensor unit 120 may be installed on the top plate 108 adjacent to the head portion of the subject 170. 1 and 2, the living-body gas detection sensor unit 120 may be positioned vertically above the subject 170 lying on the mattress 110, It is possible to easily detect the excreted living body gas.

The living body gas detection sensor unit 120 includes a fixing means 122, a position adjusting member 124, a housing 126, a gas measuring sensor 136 and a moisture restraining means 138.

The fixing means 122 makes it possible to fix the living body gas detecting sensor portion 120 to the top plate 108 of the bed. The fastening means 122 may also be removed from the top plate 108. The fixing means 122 may be changed in configuration depending on the place or position where the body information measuring apparatus 100 is applied. For example, when the body-information measuring device is coupled to the massage chair, the fixing means 122 may be realized by a vacuum adsorption device (cubicle).

The position adjusting member 124 connects the fixing means 122 and the housing 126 so that the shape of the position adjusting member 124 is deformable so that the position of the housing 126 can be changed. The position adjustment member 124 may be formed of a flexible material or may have a plurality of links to change its position. When the body information about the examinee 170 is measured by the position adjusting member 124, the housing 126 can be positioned vertically above the subject 170 as shown in FIGS. When the body information on the examinee 170 is not measured, the position adjusting member 124 is deformed to limit the movement of the examinee 170 by making the housing 126 as close as possible to the top plate 108 You can do it.

Inside the housing 126, there is provided a gas holding space 128 for collecting the living body gas and allowing it to stay for a predetermined time. The gas staying space 128 is formed by the inner inclined surface 130, so that the living body gas can be concentrated in the direction of the gas measurement sensor 136. Also, since the gas holding space 128 is opened only on the lower surface and the other surface is closed, the living body gas can stay therein. Due to the gas staying space 128, the body-information measuring apparatus 100 according to the present embodiment can measure a trace amount of living body gas.

Although the inner inclined surface 130 is illustrated as having a curved shape, it is needless to say that the inner inclined surface 130 may have various shapes such as a straight line or a stepped shape.

A side groove 134 is formed on the inner surface of the housing 126 on the inlet side. The side grooves 134 correspond to the grooves formed continuously or partly along the circumference of the housing 126. A moisture restraining means 138 is inserted into the side groove 134, and a part thereof is exposed to the gas retention space 128.

Moisture may be generated due to sweating or water vapor generated in the skin of the examinee 170 or influences due to temperature or humidity. It is difficult to accurately measure the gas component due to the influence of the presence of steam in the biological gas component to be measured. Therefore, the body-information measuring apparatus 100 according to the present embodiment includes the moisture restraining unit 138 that suppresses and removes the moisture in the gas staying space 128 of the housing 126.

The moisture restraining means 138 may be constituted by at least one of an absorbent, a desiccant, a desiccant, a drying agent, a small fan, or a combination thereof. Examples of the absorbent, the dehumidifying agent and the drying agent for removing the generated moisture include, but are not limited to, sodium polyacrylate, silica gel, calcium oxide, calcium chloride, activated carbon, By using a fan (small fan) to supply weak wind to the surface of the skin of the examinee 170, moisture may be less likely to be generated.

The operation of the moisture restraining means 138 may be associated with the measurement timing of the gas measurement sensor 136. For example, the water restraining means 138 corresponding to the small-sized blower can be operated before the measurement timing of the living body gas to the gas measuring sensor 136.

The gas measurement sensor 136 may be located at the center of the upper surface of the gas staying space 128. The gas measurement sensor 136 can measure a living body gas generated due to respiration of the examinee 170 or a living body gas generated from the skin. The living body gas stays in the gas holding space 128 of the housing 126 and the gas measuring sensor 136 measures the living body gas while being positioned inside the gas holding space 128.

The gas measurement sensor 136 is composed of, for example, a semiconductor sensor, and is configured to detect a gas component contained in the gas staying space 128, such as acetone, hydrogen, carbon monoxide, methane, hydrogen sulfide, isoprene, trimethylamine, ammonia, , Acetaldehyde, ethanol and the like are measured. Further, the gas that can be measured by the gas measurement sensor 136 is not limited to the above. The gas measurement sensor 136 is not limited to a semiconductor sensor but may be a carbon nanotube sensor, an electrochemical sensor, an optical fiber sensor, a thin film sensor, a MEMS thermally conductive sensor, a surface acoustic wave sensor, , And an electromotive force change type sensor.
