[0042]

[0043] As illustrated in FIGS. 1 to 3, the present invention relates to a signal transmission device (100) that mediates signal transmission between a sensing device (200) that detects a biosignal and a simulator (300) for testing the signal transmission performance of the sensing device (200).

[0044] According to an embodiment of the present invention, the sensing device (200) for detecting the bio-signal is a ring-shaped sensing device (200). The ring-shaped sensing device (200) is a sensing device (200) that transmits a predetermined signal toward a living body and detects a reflection signal reflected from the living body to detect and analyze various bio-signals. The sensing device (200) collects and analyzes bio-signals, and can identify and analyze bio-signals such as blood pressure, electrocardiogram, and pulse.

[0045] The simulator (300) above is a device for testing whether the sensing device (200) properly transmits a signal toward a living body and properly receives a response signal reflected from the living body. The simulator (300) itself can use a previously known tester. The sensing device (200) transmits a signal through a predetermined control unit, for example, a wired or wireless terminal such as a smart phone or a PC, and the simulator (300) generates a response signal in response to the generated signal when the generated signal transmitted from the sensing device (200) is within a predetermined condition range. When the response signal is transmitted to the sensing device (200), the validity of the signal transmitted to the sensing device (200) can be verified through the wired or wireless terminal.

[0046] The simulator (300) is provided with a connecting portion (330) to which a signal transmission device (100) according to an embodiment of the present invention is coupled. The connecting portion (330) is formed to protrude upward so as to be connected to the coupling portion (11) of the signal transmission device (100). The connecting portion (330) is provided with a plane portion for transmitting a signal, and the plane is divided such that one side comprises a receiving portion (310) for receiving a generated signal from a detection device (200) and the other side comprises a transmitting portion (320) for transmitting a response signal from the simulator toward the detection device (200). The receiving portion (310) is a photodiode for receiving the generated signal, and the transmitting portion (320) is formed with an LED for transmitting a signal to the detection device (200).

[0047]

[0048] According to an embodiment of the present invention, a signal transmission device (100) is provided to mediate signal transmission between the detection device (200) and the simulator (300), and as shown in FIGS. 1 and 2, the signal transmission device (100) includes a main body (10) and a light transmission unit (20).

[0049] The main body (10) accommodates the detection device (200) and is detachably coupled to the simulator (300). According to the present embodiment, the main body (10) includes a coupling portion (11), a mounting portion (12), and a cover portion (13).

[0050] The above-mentioned connecting portion (11) is a portion that is connected to the simulator (300), and a recessed groove is formed at the lower portion of the connecting portion so that the connecting portion (330) can be inserted. A first through-hole (112) is formed in the connecting portion (11) so that the light transmitting portion (20) can communicate with the receiving portion (310) and the transmitting portion (320) of the simulator (300). In addition, a fitting portion (111) into which the light transmitting portion (20) is fitted is formed in the connecting portion (11).

[0051] The above-described mounting portion (12) is coupled to the above-described coupling portion (11) and is a portion where the detection mechanism (200) is mounted. A protruding pin is provided on the bottom surface of the mounting portion (12) and is inserted into and fastened to the coupling portion (11). According to an embodiment of the present invention, the detection mechanism (200) is a ring-shaped ring, and the ring is mounted on the mounting portion (12). The ring-shaped detection mechanism (200) is mounted on the mounting portion (12) such that the central axis of the ring is vertical. Therefore, the upper surface of the mounting portion (14) is provided to be flat. According to the present embodiment, the upper surface of the mounting portion (12) includes an inner support portion (121) and an outer support portion (122) so that the detection mechanism (200) can be mounted.

[0052] The inner support portion (121) is disposed to face the inner surface of the ring-shaped detection device (200) and is formed to have a predetermined curvature. The outer support portion (122) is disposed to face the outer surface of the ring-shaped detection device (200) and is formed to have a predetermined curvature. The inner support portion (121) and the outer support portion (122) are spaced apart from each other by a predetermined interval, and the ring-shaped detection device (200) is inserted and disposed in the space between them. In addition, according to the present embodiment, the inner support portion (121) and the outer support portion (122) are provided in multiple numbers and spaced apart from each other. As illustrated in FIGS. 2 and 3, two inner support portions (121) are provided and spaced apart from each other, and two outer support portions (122) are provided and spaced apart from each other so as to face each of the inner support portions (121). Of course, the number of the inner support portion (121) and the outer support portion (122) is not limited thereto. In addition, a second through hole (125) through which the light transmission portion (20) passes is formed in the mounting portion (12).

[0053] The above cover part (13) is coupled to the above mounting part (12) to form a dark room. The cover part (13) is coupled from the upper side to cover the above mounting part (12), and is coupled to the above mounting part (12) while creating a predetermined internal space with the above mounting part (12).

[0054]

[0055] The above-described light transmitting unit (20) is provided inside the main body (10) to receive and transmit a generation signal transmitted from the detection device (200) toward the simulator (300) and to transmit a response signal generated by the simulator (300) in response to the generation signal to the detection device (200). The light transmitting unit (20) includes a first contact portion (21) that contacts the detection device (200) side and a second contact portion (22) that contacts the simulator (300) side. In addition, according to the present embodiment, the light transmitting unit (20) includes a guide (23) that connects the first contact portion (21) and the second contact portion (22). The first contact portion (21) that contacts the detection device (200) to receive a signal generated from the detection device (200), and the second contact portion (22) that contacts the simulator (300) to transmit the signal generated to the simulator (300) and receive a response signal from the simulator (300) are made transparent, and the remaining outer surface can be formed partially opaque. The interior of the light transmission portion (20) is made of a light-transmitting material.

[0056] According to the present embodiment, the surface of the light transmitting portion (20) can be polished to improve reflectivity. Since the light transmitting portion (20) is manufactured to have a predetermined size and shape, the problem of length deviation caused by cutting and bending of conventional optical fibers can be resolved.

[0057] According to an embodiment of the present invention, a plurality of first contact portions (21) are provided corresponding to a plurality of signal collection sensors (201) provided in the detection device (200). The plurality of signal collection sensors (201) provided in the detection device (200) are substantially the same sensors and are installed at different positions on the inner circumference of the ring-shaped ring, so that signals received at points of contact with the user's skin may be different. According to an embodiment of the present invention, tests may be performed on the signal collection sensors (201) alternately. For example, after receiving a generation signal from a first signal collection sensor (201) and transmitting it to the simulator (300), the simulator (300) transmits a response signal to the first signal collection sensor (201) to check whether the first signal collection sensor is normal, and then after receiving a generation signal from a second signal collection sensor and transmitting it to the simulator (300), the simulator (300) transmits a response signal to the second signal collection sensor to check whether the second signal collection sensor is normal.

[0058] According to the present embodiment, as illustrated in FIG. 2, the signal collection sensor (201) provided in the detection device (200) protrudes toward the center from the inner surface of the ring-shaped detection device (200), and the outer surface of the signal collection sensor (201) is formed to be round. The first contact portion (21) makes line contact or surface contact with the detection device (200). That is, the first contact portion (21) is formed to be concave inward to correspond to the round shape of the signal collection sensor (201), and makes surface contact with the outer surface of the signal collection sensor (201).

[0059] The second contact portion (22) is in surface contact with the simulator (300). Specifically, the second contact portion (22) includes a transmission contact portion (221) and a reception contact portion (22).

[0060] The above-mentioned transmission contact portion (221) contacts the receiving portion (310) of the simulator (300) through which the simulator (300) receives a signal generated from the detection device (200). The above-mentioned reception contact portion (222) contacts the transmitting portion (320) through which the simulator (300) transmits a response signal to the detection device (200). As illustrated in Fig. 4, the transmission contact portion (221) and the receiving contact portion (222) are separated from each other. The transmission contact portion (221) and the receiving contact portion (222) forming the second contact portion (22) are both formed flat.

[0061] According to the present embodiment, as illustrated in FIGS. 3 and 4, the light transmitting portion (20) is formed with a positioning projection (24) that is inserted into a positioning groove (1211) provided in the inner support portion (121). The first contact portion (21) provided on the upper side of the light transmitting portion (20) approaches between the inner support portions (121) that are spaced apart from each other, and the positioning projection (24) provided on the side of the first contact portion (21) is inserted into the positioning groove (1211), thereby fixing the position of the light transmitting portion (20). When the light transmitting portion (20) is positioned in this manner, the first contact portion (21) comes into line or surface contact with the signal collection sensor (201) of the detection device (200).

[0062] According to the present embodiment, a light sensor (124) for detecting illumination on one side of a ring-shaped detection device (200) is provided in the mounting portion (12). The light sensor (124) can detect an LED indicator light indicating the power status of the detection device (200). The light sensor (124) is installed in a sliding hole (123) formed to extend in one direction in the mounting portion (12). The light sensor (124) can move in the longitudinal direction of the sliding hole (123), and is coupled so as to be rotatable while mounted in the sliding hole (123). The above light sensor (124) can move along the sliding hole (123) and rotate in the sliding hole (123), so that when the detection mechanism (200) is seated in the mounting portion (12), the light sensor (124) can be accurately aligned with the lighting position on one side, and also, when the specification of the light sensor (124) is changed, the position of the light sensor (124) and the lighting can be easily aligned. In this way, as the light sensor (124) rotates, it enables accurate observation of the lighting portion, and since it can move along the sliding hole (123), it can rotate while moving in one direction along the sliding hole, so that the light sensor (123) can accurately sense the lighting at a more accurate position. In addition, although not shown, guide scales in the longitudinal direction and the rotational direction can be provided to identify the position at which the light sensor (124) moves along the longitudinal direction of the sliding hole (123), or the rotation angle.

[0063]

[0064] Hereinafter, the operation and effect of the signal transmission device (100) for testing a detection device that detects a biosignal according to the above configuration will be described.

[0065] As shown in FIGS. 1 and 2, a mounting portion (12) is mounted on a coupling portion (11) of a signal transmission device (100). The light transmission portion (20) is mounted by inserting a positioning projection (24) formed on the upper portion thereof through the first and second through-holes (112, 125) into a positioning groove (1211) provided on the inner support portion (121) of the mounting portion (12). In this state, the first contact portion (21) is aligned in a direction from the inner support portion (121) toward the outer support portion (122). Subsequently, a ring-shaped detection mechanism (200) is mounted and positioned on the inner support portion (121) and the outer support portion (122), and at this time, the signal collection sensor (201) of the detection mechanism (200) and the first contact portion (21) come into line or surface contact. Next, after the cover part (13) is coupled to the mounting part (12), the signal transmission device (100) is coupled to the simulator (300). When the signal transmission device (100) is coupled to the simulator (300), the second contact part (22) of the light transmission part (20) makes surface contact with the receiving part (310) and the transmitting part (320) of the simulator (300). Specifically, the transmitting contact part (221) of the second contact part (22) makes surface contact with the receiving part (310) of the simulator (300), and the receiving contact part (222) of the second contact part (22) makes surface contact with the transmitting part (320) of the simulator (300).

[0066] The above detection device (200) can be controlled by linking with an external control device, and generates a predetermined signal through the wired / wireless terminal. For example, the detection device (200) can be controlled to transmit a generation signal based on a predetermined waveform that implements a human bio-signal as a signal. The control unit can transmit a signal corresponding to a human's blood pressure, electrocardiogram, or pulse wave through the signal collection sensor (201) of the detection device (200). This signal is a generation signal, and the generation signal passes through the optical transmission unit (20) to the transmission contact unit (221) and then enters the receiving unit (310) of the simulator (300). Of course, the generation signal can be transmitted to the second contact unit (22) through the optical transmission unit (20), and the generation signal can pass to the receiving contact unit (222) corresponding to the transmission unit (320), but the function of detecting the generation signal is performed in the receiving unit (310).

[0067] The simulator (300) receives the generated signal through the receiver (310). If the simulator (300) determines that the generated signal is an appropriate signal within a predetermined error range compared to the signal applied by the control unit, the simulator (300) transmits a response signal corresponding to the generated signal through the transmitter (320). If the generated signal is transmitted to the detection device (200) again through the optical transmission unit (20), and the response signal received by the detection device (200) is determined to be within a predetermined error range, it can be determined that the signal collection sensor (201) of the detection device (200) is operating reliably.

[0068]

[0069] In this way, the signal transmission device (100) for testing the detection device (200) according to the present invention can provide the effect of enabling reliable verification of the detection device by reducing the deviation of the optical path by transmitting the light signal transmitted by the conventional optical fiber through the pre-fabricated channel-shaped light transmission device (20) when light is transmitted through the optical transmission unit (20) inside the signal transmission device (100) forming a dark room, and can provide the effect of quickly determining whether the detection device is defective and significantly reducing the defect rate.

[0070] In addition, the signal transmission device (100) according to the embodiment of the present invention provides an effect of preventing damage to the contact portion of the detection device (200) or simulator (300) by both ends of the optical fiber when transmitting signals using a conventional optical fiber, since the optical transmission unit (20) is in line or surface contact with the detection device (200) and in surface contact with the simulator (300).

[0071] In addition, the generation signal of the detection device (200) is vertically incident on the receiving unit (310) by the transmission contact unit (221), and the response signal of the simulator (300) is vertically transmitted from the transmission unit (320) to the transmission contact unit (221), so that the signal transmission device (100) according to the present invention can reliably secure signal transmission and response characteristics by preventing optical loss in advance in relation to the simulator (300).

[0072]

[0073] Meanwhile, according to another aspect of the present invention, an optical structure used in a signal transmission device (100) for testing a sensing device that detects the biosignal is provided. In practice, the optical structure is identical to the optical transmission unit (20) constituting the signal transmission device (100). Specifically, the optical structure receives a generation signal transmitted from a sensing device (200) and transmits a response signal generated by the simulator (300) in response to the generation signal to the sensing device (200), and includes a first contact portion (21) that contacts a sensor for collecting a biosignal of the sensing device (200), a second contact portion (22) that contacts the simulator (300) side, and a guide portion (23) that connects the first contact portion (21) and the second contact portion (22) to provide a path for light to pass through, and is made of a transparent material.

[0074] In addition, in the present embodiment, the detection device (200) is a ring-shaped detection device (200) formed in a ring shape, and the first contact portion (21) is provided in plurality corresponding to a plurality of signal collection sensors (201) provided in the detection device (200) and makes line contact or surface contact with the detection device (200). The first contact portion (21) makes surface contact so as to receive light from the signal collection sensor (201).

[0075] And, the second contact portion (22) makes surface contact with the simulator (300). As illustrated in FIG. 4, the second contact portion (22) includes a transmission contact portion (221) that contacts the receiving portion (310) of the simulator (300) through which the simulator (300) receives a signal generated from the detection device (200), and a receiving contact portion (222) that contacts the transmitting portion (320) through which the simulator (300) transmits a response signal to the detection device (200), and the transmission contact portion (221) and the receiving contact portion (222) are separated from each other.

[0076] The above guide portion (23) is formed as a tubular channel and transmits an optical signal to the first contact portion (21) and the second contact portion (22).
