Description

Body-attached biosignal acquisition device

Technical Field

The present invention relates to a body-attached type biosignal acquisition device, and more particularly, to a biosignal acquisition device that can acquire a high-quality biosignal by being attached to a body such as a leg of an infant.

Background

The condition of premature infant or even normal infant, dying 3 months before, due to birth defects or inability to breathe when lying down, is called Sudden Infant Death Syndrome (SIDS). In case of emergency such as sudden infant death syndrome, parents of infants want to find and treat as early as possible. However, in order to find an emergency at an early stage, it is necessary to continuously monitor a bio signal (Biometric signal) such as oxygen saturation. The detection of the bio-signal may be achieved by a medical device comprising a bio-signal sensor. However, these medical devices are not only expensive but also large, and thus, are difficult to use in ordinary homes.

Therefore, there is a need for a biosignal acquisition device that is attached to the body of an infant and notifies a guardian of an abnormality and takes an emergency measure when the abnormality occurs, instead of always taking care of the infant in a normal home. The device can prevent death in an emergency such as sudden infant death syndrome by measuring vital biological signals related to the breathing of the infant, such as pulse and blood oxygen saturation.

In recent years, a bio-signal sensor such as a PPG sensor capable of measuring oxygen saturation has been miniaturized and produced at low cost, and with the development of wireless communication technology such as bluetooth, a bio-signal acquisition function has been installed in a terminal of a smart phone, a smart wristband, or a smart watch. However, such terminals are not suitable for monitoring infants for emergency situations. Namely, it is pointed out that it is difficult to maintain stable and continuous contact of the sensor, and that skin and hygiene problems are not taken into consideration.

If the sensors are not in close contact, there are problems of light leakage and dynamic noise. In particular, in the case of the light leakage phenomenon, a normal biological signal cannot be obtained and distortion occurs. To prevent this, it is conceivable to bring the sensor into close contact with the skin by fastening with a body-fixing means such as a strap (strap). However, a problem of redness of the skin of the infant may occur. Therefore, there is a demand for a structure that can achieve both reliability of acquiring a biological signal and health of the skin by keeping a proper pressure and bringing a sensor into close contact with the skin even if the size of the body changes according to the difference in the age of the infant and the difference in the individual. However, the above-described conventional apparatus has difficulty in satisfying these needs.

Therefore, although not explicitly described or shown in the present specification, those skilled in the art can appreciate the principle of the present invention and can present various devices within the concept and scope of the present invention. Further, it should be understood that all the terms and embodiments listed in the specification are only used for clear understanding of the concept of the present invention in principle, and are not limited to the specifically listed embodiments and states.

The above objects, features and advantages of the present invention will become more apparent from the following detailed description related to the accompanying drawings, and thus, the technical idea of the present invention can be easily implemented by those skilled in the art.

It should also be understood that not only the principles, concepts and embodiments of the invention, but also all detailed descriptions of specific embodiments which follow, are intended to cover both structural and functional equivalents thereof. It is also to be understood that such equivalents are not related to currently known equivalents or equivalents to be developed in the future, and include all elements that perform the same function. In describing the present invention, if it is determined that the detailed description of the related known technology of the present invention will obscure the gist of the present invention, the detailed description thereof will be omitted.

Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1a and 1b are diagrams illustrating a body-adhering type biosignal acquisition apparatus according to an embodiment of the present invention. As shown in fig. 1a and 1b, the body-adhering type biosignal acquisition device 10 of the present invention includes: a main body 100 provided with a sensor 110 for acquiring a biological signal in a state of being in close contact with the surface of a body 900; a detachable part 200 detachable from the main body 100; and a fixing part 300 including a first strap 310 and a second strap 320 which are disposed in parallel with each other and can wrap the body 900, respectively, for coupling the main body 100 and the detachable part 200 to the body 900. The first strap 310 and the second strap 320 are arranged in parallel, so that the device 10 can be prevented from slipping down below the ankle.

The bio-signal may be at least one of oxygen saturation, heartbeat, electrocardiogram, body temperature, blood glucose, and body fluid secretion. In particular, when the bio-signal is oxygen saturation, the sensor 110 may be a module (PPG sensor) including a photodiode and a light emitting diode, and a ratio of current values of infrared and red light signals is calculated by measuring a current value obtained by projecting or reflecting the infrared and red light signals toward the skin by the module, and then a ratio of oxyhemoglobin is obtained and oxygen saturation may be obtained using the ratio. For this purpose, it is necessary to be located at the lower part of the main body 100 (the surface facing the surface of the body 900 when attached to the body 900). The sensor 110 is brought into close contact with the skin portion of the body 900 through which the arterial blood vessels pass and operated so that normal biological signals can be obtained. Referring to fig. 1a and 1b, in order to bring the sensor 110 into close contact with the surface of the body 900, the sensor 110 is formed to protrude from the surface of the main body 100. Such a protruding structure can also be held in close contact in the case of different body sizes.

The first strap 310 is attached to the detachable portion 200 or is formed integrally with the detachable portion 200. Here, the term "attached" means that they are assembled to each other after being formed separately, and the term "integrally formed" means that they are formed as one by a method such as injection molding. An unevenness 210 capable of supporting a pressure generated between the sensor 110 and the surface of the body 900 is formed on a surface of the detachable portion 200 coupled to the main body 100. Even if the detachable portion is made of a flexible (elastic) material, the pressure generated when the sensor 110 and the body 900 are in close contact with each other can be supported by the concave-convex portion 210 formed in this manner.

The body 900 may be a human lower leg. Particularly preferably the calf of an infant. Lower leg refers to the portion of a person's leg below the knee joint. In particular, the sensor 110 is preferably attached to the inside of the ankle or the outside of the ankle. Because the person's lower leg is a convexly streamlined shape, the second strap 320 effectively prevents the device 10 from slipping under the ankle when the device 10 of the present invention is attached, as shown in fig. 1 a.

In order to obtain a bio-signal, such as a PPG signal, from an infant, toes are used in existing medical devices. Recently, attempts have been made to utilize the sole, thigh, wrist, and the like. However, in order to stably obtain a bio-signal in a general household, it is necessary to select an attachment position which can be easily attached and detached and supported and can minimize inconvenience felt by a baby, and the calf is a solution for this.

Fig. 2a and 2b are diagrams showing a body-attachment state of a body-attachment type biosignal acquisition apparatus according to an embodiment of the present invention. As shown in fig. 2a and 2b, the fixing part 300 may further include a connector 330, and the connector 330 connects the first and

second straps

310 and 320 or connects the detachable part 200 and the second strap 320, maintaining a space between the first and

second straps

310 and 320. In particular, the length of the connecting member 330 is preferably adjustable by the user. As shown in fig. 2a, when the body is small, the connecting member 330 is adjusted to be short, and as shown in fig. 2b, when the body is large, the connecting member 330 is adjusted to be long. Such length adjustment can be achieved by providing the connector 330 with velcro (velcro) or a buckle (buckle) or a plurality of buttons (button), snap (snap fastener), magnet (magnet), etc. However, without being limited to a name, it may be implemented with a concave-convex structure capable of coupling with each other. In fig. 2a and 2b, the shape of the connecting member 330 is shown by a straight-line type strap, but the shape is not limited thereto, and may be embodied by various shapes such as two or three rows of straps, a curved shape, and the like.

Fig. 3a and 3b are diagrams illustrating a shape of a strap according to an embodiment of the present invention. As shown in fig. 3a and 3b, the interval between the first and

second bands

310 and 320 is preferably gradually increased toward the ends of the first and

second bands

310 and 320. In this manner, the flared configuration helps prevent the

straps

310, 320 from lifting off the surface of the lower leg when wrapped around the convex, streamlined lower leg.

The first strap 310 and the second strap 320 include

coupling members

311, 312, 321, 322 coupled to each end, respectively. Specifically, as shown in fig. 3a and 3b, a first coupling member 311 and a second coupling member 312 are formed at both ends of a first strap 310, respectively, and when the first strap 310 wraps the body 900, the first coupling member 311 and the second coupling member 312 are coupled to each other. And, a first coupling piece 321 and a second coupling piece 322 are respectively formed at both ends of the second strap 320, and when the second strap 320 wraps the body 900, the first coupling piece 321 and the second coupling piece 322 are coupled to each other.

Fig. 4a and 4b are diagrams illustrating a coupling state of a coupling member according to an embodiment of the present invention. As shown in fig. 4a and 4b, when the circumference of the body 900 changes (fig. 4a and 4b), the positions or areas where the

coupling members

311, 312, 321, 322 are coupled are preferably adjustable by the user so that the first strap 310 and the second strap 320 can be closely attached to the surface of the body 900, respectively. The adjustment of the position or area of the coupling may be achieved by providing the

coupling members

311, 312, 321, 322 with velcro (velcro) or a buckle (buckle) or a plurality of buttons (snap), snap fasteners (snap), magnets (magnet), or the like. However, without being limited to a name, it may be implemented with a concave-convex structure capable of coupling with each other.

Fig. 4b shows a case where the circumference of the body 900 is shortened as compared with the case of fig. 4a, and it can be known that the coupling area of the first coupling member 311 and the second coupling member 312 of the first band 310 is adjusted to be wider than the case of fig. 4 a.

Fig. 5a and 5b are diagrams illustrating a coupling state of a plurality of coupling elements according to an embodiment of the present invention. As shown in fig. 5a and 5b, the

coupling pieces

311, 312, 321, and 322 of one or more of the first strap 310 and the second strap 320 may be configured such that when at least one of the straps wraps the body 900, both sides of the one or more straps are fixed at any angle. Since the three-dimensional radius of the lower leg of the infant and the curvature of the lower leg are different depending on the age of the infant and the individual physical characteristics of the infant, the two sides of the band can be fixed at any angle, and the band can be tightly attached to the infant along the curved surface with uniform pressure. Such a structure that is fixed in a state of an arbitrary angle can be realized by providing the

coupling members

311, 312, 321, and 322 with velcro (velcro), a buckle (buckle), a plurality of buttons (snap), snap fasteners (snap), or a magnet (magnet). In particular, when the snap fastener or the magnetic fastener is provided, the

straps

310 and 320 are preferably formed of medical silicone or a material having elasticity such as rubber and friction force in order to be fixed to prevent mutual rotation.

As shown in fig. 1b, one surface of each of both sides of the first strap 310 facing the body 900 may be formed with one or more protrusions 315 and one or more valleys 314 to prevent the first strap 310 from rotating in a circumferential direction of the body 900 when the first strap 310 wraps the body 900. The protrusions 315 and the valleys 314 are formed in an elastic structure suitable for the bending of the first strap 310 so that the skin can be pressed with an appropriate strength according to the change in the size of the body 900 according to the age of the infant to which the device 10 is attached. The protrusions 315 and valleys 314 have a function of dispersing pressure that may be concentrated on the skin portion in contact with the sensor due to the protruding shape of the sensor 110. As the age of the infant to which the device 10 is attached increases and the body 900 becomes larger, the number of the projections 315 or valleys 314 is preferably adjusted accordingly. This process may be embodied by variably adding the structure of the protrusions 315 and valleys 314 or replacing the entire first strap 310.

The protrusions 315 and the valleys 314 are closer to the detachable portion 200 than the end of the first strap 310. As shown in fig. 1b, the protrusion 315 is formed in a streamline shape having a slow curvature, and is preferably adapted to be worn on the curved surface of the ankle of an infant from less than 1 month to 12 months old.

Fig. 6a and 6b are views showing the concave and convex shapes of the detachable portion according to an embodiment of the present invention. The cross section of the concavity and convexity 210 may be a curved surface shape. By designing the cross section to be curved, the main body 100 can be easily attached and detached. In particular, as shown in fig. 6a and 6b, the cross section of the unevenness 210 is preferably "S" shaped. By designing the sensor 110 in the "S" shape, the surface supporting the main body (see the arrow in fig. 6 a) when pressure is generated between the sensor and the skin of the body 900 is enlarged, or a plurality of surfaces supporting the main body (see the arrow in fig. 6 b) are formed, so that the pressure can be sufficiently supported.

Also, a protrusion or a groove may be formed on one or more surfaces of the first strap 310 or the second strap 320 facing the body 900. The protrusions or grooves may serve to ventilate and prevent sweat from entering the skin.

In addition, all or part of the detachable portion 200 is preferably made of an elastic material. That is, in the detachable section 200, at least a portion in contact with the main body 100 where the unevenness 210 is formed is made of an elastic material, and therefore, it is preferable that the main body 100 be detachably formed. The elastic material can be medical silicone. The medical silicone resin is harmless and sanitary, and is made of an elastic material and can properly maintain its shape when an external force is applied. Further, the detachable portion 200 and the first strap 310 may be integrally formed of medical silicone.

The above description is illustrative of the technical idea of the present invention, and various modifications, changes, and substitutions can be made by those skilled in the art without departing from the essential characteristics of the present invention.

Therefore, the embodiments and drawings disclosed in the present invention do not limit the technical idea of the present invention, but are used to explain the technical idea of the present invention, and the technical idea scope of the present invention is not limited by the embodiments and drawings. The scope of the present invention should be construed in accordance with the scope of the claims, and all technical ideas included in the scope equivalent thereto are also included in the scope of the claims.
