[0038] Hereinafter, the present invention will be described in detail with reference to the attached drawings.

[0039]

[0040] FIG. 1 is a schematic diagram of a wearable device and a charger according to an embodiment of the present invention, and FIG. 2 is a schematic diagram of the configuration of a wearable device according to an embodiment of the present invention. Here, (a) of FIG. 1 is a schematic diagram of a wearable device of the present invention, and (b) of FIG. 1 is a schematic diagram of a charger of the present invention.

[0041] As shown in FIGS. 1 and 2, the wearable device of the present invention includes a housing (160) having a ring shape and an internal space; a sensor unit (110) coupled to the housing (160) and in contact with the user's skin to measure the user's pulse wave; a communication unit (130) that receives and processes a signal from the sensor unit (110) to generate a transmission signal, which is a transmitted signal; and an analysis unit (120) that receives and analyzes the transmission signal. In addition, the analysis unit (120) can analyze the user's pulse wave information to determine whether the user has glaucoma.

[0042] The housing (160) has a ring shape and can be worn on the user's finger, and accordingly, the inner surface of the housing (160) can be in contact with the user's finger skin. The outer surface of the housing (160) exposed to the outside can be formed of a metal material such as titanium or stainless steel (SUS), and the inner surface of the housing (160) can be formed of a non-metal such as plastic. However, the material forming each part of the housing (160) is not limited to this, and it goes without saying that various materials can be used.

[0043] The wearable device of the present invention may further include a vibration unit (140) that receives an operating signal from the analysis unit (120) and transmits vibration to the user's skin, thereby transmitting a health abnormality signal to the user.

[0044] Specifically, when the analysis unit (120) determines that the user has glaucoma through the following process, the analysis unit (120) transmits an operating signal to the vibration unit (140), and the vibration unit (140) generates vibration in response to the operating signal, thereby transmitting the vibration from the vibration unit (140) to the user's skin, thereby allowing the user to recognize that he or she has glaucoma.

[0045] The wearable device of the present invention may further include an elastic part formed in the internal space of the housing (160) to allow the sensor part (110) to come into close contact with the user's skin and to allow the vibration part (140) to come into close contact with the user's skin.

[0046] The elastic member may include a first elastic body (151) having elasticity and formed in the internal space of the housing (160) and coupled with the sensor member (110) to press the sensor member (110) toward the center of the housing (160), and a second elastic body (152) having elasticity and formed in the internal space of the housing (160) and coupled with the vibrating member (140) to press the vibrating member (140) toward the center of the housing (160).

[0047] As shown in Fig. 2, a portion of the sensor portion (110) may protrude on the inner surface of the housing (160), and a portion of the vibration portion (140) may also protrude on the inner surface of the housing (160).

[0048] And, when the user's finger is inserted into the housing (160), the skin of the user's finger presses the protruding portion of the sensor portion (110) and the protruding portion of the vibration portion (140), respectively, and at the same time, the pressing force of the first elastic body (151) and the pressing force of the second elastic body (152) corresponding to the pressing force of the finger are transmitted to the sensor portion (110) and the vibration portion (140), respectively, so that the sensor portion (110) and the vibration portion (140) can be in close contact with the skin of the user's finger.

[0049] Accordingly, the vibration transmission efficiency of the vibration unit (140) to the user's finger is increased, and the pulse measurement precision and sensitivity, etc., when the sensor unit (110) measures the pulse of the blood vessels under the skin of the user's finger can be improved.

[0050] The wearable device of the present invention may further include a battery (170) formed in the internal space of the housing (160) and supplying electricity to the sensor unit (110), the communication unit (130), and the analysis unit (120). In addition, electricity may be supplied from the battery (170) to the vibration unit (140). Such a battery (170) may be formed as a rechargeable type and may operate by supplying electricity to each of the above-described components.

[0051] The analysis unit (120) may be formed in the internal space of the housing (160) or on the outside of the housing (160). FIG. 2 illustrates that the analysis unit (120) is formed in the internal space of the housing (160), but the analysis unit (120) may also be formed on the outside of the housing (160). Specifically, the analysis unit (120) may be installed in an external electronic device such as a computer, smartphone, tablet PC, or smartwatch to perform the same function.

[0052]

[0053] Fig. 3 is a flowchart of a blood pressure measurement process of an analysis unit (120) according to an embodiment of the present invention, and Fig. 4 is a measurement graph by a photoplethysmography sensor according to an embodiment of the present invention. In Fig. 4, the horizontal axis is the number of detections and the vertical axis is the detection intensity value (dimensionless number compared to the maximum detection intensity value) by the photoplethysmography (PPG) sensor.

[0054] As shown in Fig. 3, in order to measure the user's blood pressure, the analysis unit (120) may perform a peak measurement step (S111) of measuring the time difference between the primary peak and the secondary peak that appear when measuring the pulse wave; a height selection step (S112) of selecting the user's height; an SI calculation step (S120) of calculating the SI value; and a blood pressure measurement step (S130) of deriving the user's blood pressure value using the SI value.

[0055] In order to perform the peak measurement step (S111) and the height selection step (S112), the analysis unit (120) can derive the vascular stiffness (Stiffness Index, SI) using the pulse wave information. Here, the vascular stiffness (SI) can be calculated by the following [Mathematical Formula 1].

[0056] [Mathematical Formula 1]

[0057] SI=h / ΔT

[0058] Here, SI is the vascular stiffness index (SI) value, h is the user's height, and ΔT is the time difference between the primary peak and the secondary peak that appear when measuring the user's pulse wave.

[0059] Information about the height of a user wearing the wearable device of the present invention may be stored in advance in the analysis unit (120), and the sensor unit (110) is equipped with a photoplethysmography (PPG: Photo-PlethysmoGraphy) sensor, so that, as shown in FIG. 4, the sensor unit (110) can continuously detect each of the primary peak and secondary peak of the pulse wave over time.

[0060] At this time, the pulse graph is a graph of a wave formed by multiple unit waves as one-cycle waves having one-cycle wavelength (λ), and each unit wave may have a first peak (a in Fig. 4) and a second peak (b in Fig. 4).

[0061] In addition, the photoplethysmography sensor of the sensor unit (110) can continuously detect the first peak and second peak of the user's pulse wave by continuously detecting the pulse wave, and the analysis unit (120) can use this to calculate the vascular stiffness (SI) as described above, thereby calculating the vascular stiffness (SI) value over time.

[0062] And, the analysis unit (120) can derive the user's blood pressure value by using the user's blood vessel stiffness value according to [Mathematical Formula 2] below.

[0063] [Equation 2]

[0064] BP=a*ln(SI)+b

[0065] Here, BP is blood pressure, SI is vascular stiffness, and a and b are each constants predetermined for each user. When the user of the wearable device of the present invention is determined, the SI value can be measured in advance using the wearable device of the present invention and the user's blood pressure can be measured using an external device, and the data thereon can be input into the analysis unit (120). The analysis unit (120) can use such data to derive the values ​​of a and b of [Mathematical Formula 2] and store them as constants of [Mathematical Formula 2].

[0066] As described above, blood pressure can be measured in the analysis unit (120), and such blood pressure is derived from an SI value, and thus, changes in the user's blood pressure over time can also be derived based on changes in the SI value over time. Such changes in blood pressure can be measured as changes in the mean arterial pressure (MAP) as described below.

[0067] That is, by measuring the mean arterial pressure for multiple pulses in units of hours, the fluctuations thereof can be measured and utilized, and this will be explained in more detail below.

[0068]

[0069] Figures 5 to 7 are graphs for mean intraocular pressure, mean arterial pressure, and mean ocular perfusion pressure, respectively.

[0070] Here, FIG. 5 is a graph of the hourly mean intraocular pressure (IOP) measured during a predetermined measurement time during the day for two patients (Patient 1, Patient 2), FIG. 6 is a graph of the hourly mean arterial pressure (MAP) measured during a predetermined measurement time during the day for the two patients (Patient 1, Patient 2), and FIG. 7 is a graph of the hourly mean ocular perfusion pressure (MOPP) measured during a predetermined measurement time during the day for the two patients (Patient 1, Patient 2).

[0071] In each of the graphs in FIGS. 5 to 7, the horizontal axis represents time, and the vertical axis represents mean intraocular pressure (IOP), mean arterial pressure (MAP), and mean ocular perfusion pressure (MOPP), respectively.

[0072] As shown in Figure 5, when comparing the graphs of Patient 1 and Patient 2, it can be confirmed that the average intraocular pressure (IOP) fluctuation value of Patient 1 is greater, and Patient 1 can be determined to have glaucoma. (In the case where the IOP fluctuation value exceeds 5, it is diagnosed as having glaucoma.)

[0073] As shown in Figure 6, when comparing the graphs of Patient 1 and Patient 2, it can be seen that the mean arterial pressure fluctuation (MAP fluctuation) is formed during the measurement time, and similar to the occurrence of fluctuations in the mean intraocular pressure fluctuation (IOP fluctuation), the mean arterial pressure fluctuation (MAP fluctuation) of Patient 1 is larger. (Patient 1: 23.3, Patient 2: 11.3)

[0074] In this regard, in an experimental measurement of the correlation between computed blood pressure and intraocular pressure, a correlation (correlation: 0.94) was confirmed in that when systolic blood pressure increases by 10 mmHg, intraocular pressure increases by 0.24 mmHg, and when diastolic blood pressure increases by 10 mmHg, intraocular pressure increases by 0.4 mmHg.

[0075] In addition, as shown in Figure 7, when comparing the graph of Patient 1 and the graph of Patient 2, the mean ocular perfusion pressure fluctuation (MOPP fluctuation) graph is formed similarly to the graph of mean arterial pressure fluctuation (MAP fluctuation), and similar to the occurrence of fluctuation range of mean intraocular pressure fluctuation (IOP fluctuation), it can be confirmed that the mean ocular perfusion pressure fluctuation (MOPP fluctuation) of Patient 1 is larger. (Patient 1: 27.3, Patient 2: 7.3)

[0076] As described above, it can be confirmed that the trend of the average intraocular pressure fluctuation (IOP fluctuation) value per patient is related to the trend of the average arterial pressure fluctuation (MAP fluctuation) value per patient and the trend of the average ocular perfusion pressure fluctuation (MOPP fluctuation) value.

[0077] That is, the user's blood pressure fluctuation affects the average intraocular pressure fluctuation (IOP fluctuation), and patients with severe average intraocular pressure fluctuation (IOP fluctuation) have a high incidence of glaucoma, i.e., they can be used for diagnosis as having symptoms of glaucoma.

[0078] By the above principle, the analysis unit (120) can determine that the user has glaucoma if the average mean arterial pressure (MAP) fluctuation value of the user during the measurement period is greater than a predetermined value.

[0079] Specifically, the analysis unit (120) stores a reference variation value, which is a variation value of the mean arterial pressure that serves as a reference for a user wearing the wearable device of the present invention, and the analysis unit (120), which receives a signal from the sensor unit (110) as described above and derives the user's blood pressure variation, can continuously measure the variation value of the mean arterial pressure by hour, and when the analysis unit (120) analyzes that the variation value of the user's mean arterial pressure exceeds the reference variation value during the measurement of the variation value of the mean arterial pressure by hour within a preset measurement period, the analysis unit (120) can determine that the user has glaucoma.

[0080] And, an operating signal is transmitted from the analysis unit (120) to the vibration unit (140), the vibration unit (140) operates, and the vibration of the vibration unit (140) is transmitted to the user's finger, so that the user can confirm that he or she has glaucoma.

[0081]

[0082] A glaucoma monitoring system can be formed, including a wearable device of the present invention as described above, and a charger that is selectively combined with the wearable device of the present invention to perform charging.

[0083] As shown in (b) of Fig. 1, the charger may include a body (210) that wirelessly charges a battery (170) when adjacent to the wearable device of the present invention; and a holder (220) that is formed by protruding from the upper surface of the body (210) and into which the wearable device of the present invention is fitted.

[0084] In addition, a terminal (211) that is connected to a power cable and receives electricity from a power source is formed on the body (210), and an indicator (221) that displays with light whether the battery (170) is being charged, whether the battery (170) is fully charged, etc. (each distinguished by color) can be formed on the upper surface of the holder (220).

[0085] In addition, the glaucoma monitoring system may further include a central processing unit formed outside the wearable device of the present invention, which receives information from a plurality of wearable devices and performs collection and analysis of the information.

[0086] The central processing unit can classify users into each patient group using information from multiple wearable devices, and perform analysis on the trends of mean arterial pressure fluctuation (MAP fluctuation), mean intraocular pressure fluctuation (IOP fluctuation), and mean ocular perfusion pressure fluctuation in each patient group, and can derive the above-mentioned reference fluctuation value that serves as a diagnostic criterion in each patient group using patient diagnosis data according to intraocular pressure input into the central processing unit.

[0087] Here, in order to classify patient groups, patient information such as gender, patient age, patient height and weight, etc. can be used. The central processing unit can also receive information on the wearing user from the analysis unit (120), and if the user belongs to a certain patient group, selects a standard variation value suitable for the patient group and transmits it to the analysis unit (120), and the analysis unit (120) can perform the above analysis judgment using the standard variation value.

[0088]

[0089] When using the wearable device of the present invention as described above, the mean arterial pressure fluctuation (MAP fluctuation) is derived by measuring the user's pulse wave, and whether the user has glaucoma is determined based on the mean arterial pressure fluctuation information, so that the measurement is quick and the onset of glaucoma can be easily determined and analyzed.

[0090] In addition, when using the wearable device of the present invention, the wearable device of the present invention is always worn on the user's finger, and pulse wave measurement, etc. is performed in real time, and continuous analysis of disease occurrence is performed, so that the accuracy and speed of disease diagnosis can be improved.

[0091] Hereinafter, a method for monitoring glaucoma symptoms using the wearable device of the present invention will be described.

[0092] First, in the first step, the sensor unit (110) can detect the user's pulse wave. Then, in the second step, the pulse wave information is transmitted from the sensor unit (110) to the analysis unit (120), and the analysis unit (120) can derive the vascular stiffness index (Stiffness Index, SI) using the pulse wave information.

[0093] Next, in the third step, the analysis unit (120) can derive the user's blood pressure value using the user's vascular stiffness value, and derive the user's average mean arterial pressure (MAP) value for each hour within the measurement period. Then, in the fourth step, the analysis unit (120) can determine that the user has glaucoma if the user's average arterial pressure fluctuation value is greater than a predetermined value.

[0094] The remaining details of the glaucoma monitoring method of the present invention are the same as those described for the wearable device of the present invention described above.
