近年來，由於高齡化及飲食習慣的改變，心血管疾病(例如腦中風)有逐年增加的趨勢而嚴重威脅人類的生命。根據近幾年醫學文獻的報導，脈搏以及血氧濃度(blood oxygen saturation)可以提供許多關於心血管方面的生理參數，因此，若能隨時量測脈搏以及血氧濃度等生理參數，對心血管疾病的預防有相當多的助益。 In recent years, due to aging and changes in eating habits, cardiovascular diseases (such as strokes) have been increasing year by year and seriously threaten human life. According to medical literature reports in recent years, pulse and blood oxygen saturation can provide many physiological parameters about cardiovascular disease. Therefore, if physiological parameters such as pulse and blood oxygen concentration can be measured at any time, cardiovascular disease can be measured. The prevention has considerable benefits.
為了提早發現或監測心血管方面的病變，有業者開發出一種光學式的量測裝置，其可像耳機一般置於耳道內來量測耳道的微循環血液，進而得到脈搏及血氧濃度等生理參數，因此，不僅在居家照護上，或是在預防醫學的領域上都有相當龐大的市場。 In order to detect or monitor cardiovascular lesions early, the industry has developed an optical measuring device that can be placed in the ear canal like a headphone to measure the microcirculation blood of the ear canal, thereby obtaining pulse and blood oxygen concentration.

In addition, the illustrations of all the embodiments of the present invention are merely illustrative and do not represent true dimensions and proportions.
請分別參照圖1A至圖1C所示，其中，圖1A為本發明較 佳實施例之一種耳道式量測裝置1的示意圖，圖1B為耳道式量測裝置1的功能方塊示意圖，而圖1C為耳道式量測裝置1使用時的示意圖。 Please refer to FIG. 1A to FIG. 1C respectively, wherein FIG. 1A is a comparison of the present invention. A schematic diagram of an ear canal measuring device 1 of the preferred embodiment, FIG. 1B is a functional block diagram of the ear canal measuring device 1, and FIG. 1C is a schematic view of the ear canal measuring device 1.
本發明之耳道式量測裝置1可像習知之耳道式耳機般配戴於人體的耳道內。其中，耳道式量測裝置1包括一耳機本體11、一可變機構12以及一感測模組13。另外，耳道式量測裝置1更包括一聲音模組14、一控制模組15、一運算模組16及一傳輸模組17。 The ear canal measuring device 1 of the present invention can be worn in the ear canal of a human body like a conventional ear canal earphone. The ear canal measuring device 1 includes a headphone body 11 , a variable mechanism 12 , and a sensing module 13 . In addition, the ear canal measuring device 1 further includes a sound module 14, a control module 15, a computing module 16, and a transmission module 17.
可變機構12與耳機本體11連接，並可與人體之外耳道緊密結合。在本實施例中，可變機構12係為一機械式的可變結構，而其材料可包含矽膠或橡膠、或其它軟性材料。其中，可變機構12具有一耳塞墊121及一彈性件122，耳塞墊121與耳機本體11連接，並包覆彈性件122，且感測模組13係設置於彈性件122上。換言之，如圖1A所示，本實施例之耳塞墊121係為具有彈性的構件(例如為一簧片)而與耳機本體11連接，在配戴時，耳塞墊121係塞入外耳道內，透過軟性材質的耳塞墊121，可使耳道式量測裝置1緊密貼合於人體的外耳道內。不過，由於每個人的外耳道尺寸不相同，因此，本發明係透過由耳機本體11內延伸至耳塞墊121之彈性件122，使耳塞墊121可頂抵並緊密地貼合於外耳道內，以下將再進一步說明。 The variable mechanism 12 is coupled to the earphone body 11 and is tightly coupled to the ear canal outside the human body. In the present embodiment, the variable mechanism 12 is a mechanical variable structure, and the material thereof may comprise silicone or rubber, or other soft materials. The variable mechanism 12 has an earplug pad 121 and an elastic member 122. The earplug pad 121 is connected to the earphone body 11 and covers the elastic member 122. The sensing module 13 is disposed on the elastic member 122. In other words, as shown in FIG. 1A, the earplug pad 121 of the present embodiment is connected to the earphone body 11 by a resilient member (for example, a reed). When worn, the earplug pad 121 is inserted into the external auditory canal. The soft material earplug pad 121 allows the ear canal measuring device 1 to be closely attached to the external auditory canal of the human body. However, since the size of the external auditory canal of each person is different, the present invention allows the earplug pad 121 to be abutted and tightly fitted into the external auditory canal through the elastic member 122 extending from the earphone body 11 to the earplug pad 121. Further explanation.
另外，為了讓不同耳朵外型的不同使用者配戴耳道式量測裝置1時都能固定於同樣的位置，因此，如圖1A及圖1C所示，本實施例之耳道式量測裝置1更具有一耳套墊18，耳套墊18與耳機本體11連接。其中，耳套墊18為一軟性的矽膠墊，使耳道式量測裝置1可以塞在人體耳廓上的三角空間，增加耳道式量測裝置1與耳朵的密合度，讓不同耳朵外型的使用者配戴時都能固定於耳廓上的三角空間內。 In addition, in order to allow different users of different ear shapes to be fixed in the same position when wearing the ear canal measuring device 1, the ear canal measurement of the present embodiment is shown in FIG. 1A and FIG. 1C. The device 1 further has an ear pad 18 that is coupled to the earphone body 11. The earmuff pad 18 is a soft silicone pad, so that the ear canal measuring device 1 can be inserted into the triangular space on the auricle of the human body, and the adhesion between the ear canal measuring device 1 and the ear is increased, so that the ear can be different from the ear. The user can be fixed in the triangular space on the auricle when wearing.
感測模組13設置於可變機構12內。感測模組13可包含軟體、硬體或韌體。於此，如圖1B所示，感測模組13具有一發光元件131及一光學感測元件132。在實施上，感測模組13也可具有複數發光元件131及複數光學感測元件132，並不加以限定。其中，發光元件131可發出一光線射向外耳道，當光線經由外耳道的反射或光線由外耳道進入人體繞射而出時可被光學感測元件132所接收，光學感測元件132接收後輸出一感測 訊號SS，而感測訊號SS係為一光體積變化訊號。由於人體脈搏產生時，全身血管的血流量亦會產生變化，代表血管內的血紅素及去氧血紅素的含量也會改變。其中，血紅素及去氧血紅素對於特殊波長的光線具有相當敏感的特性(例如：紅光、紅外光或綠光)，因此若以發光元件131(如發光二極體)發出紅光、紅外光或綠光(紅光的波長範圍為622~770nm，紅外光的波長範圍為771~2500nm，綠光的波長長範圍為492~577nm)射向外耳道皮膚底下的組織及血管，然後以光學感測元件132(如光敏元件)接收反射或穿透過皮膚的光線，透過接收回來的光線強弱，可得到血管內血流變化的情形，這種變化稱之為光體積變化信號(Photoplethysmography,PPG)。PPG是一種因血液循環系統而產生的物理量，當心臟在收縮及舒張時，血管內單位面積的血流量會造成週期性的變化。由於PPG信號變化是因心臟搏動造成，因此，光學感測元件132所接收的反射或繞射之光線能量程度即可對應到脈搏。因此，透過耳道式量測裝置1可量測到人體的脈搏及血氧濃度的變化，以及與耳道相關之生理資訊。 The sensing module 13 is disposed in the variable mechanism 12. The sensing module 13 can comprise a soft body, a hardware or a firmware. As shown in FIG. 1B , the sensing module 13 has a light emitting component 131 and an optical sensing component 132 . In practice, the sensing module 13 may also have a plurality of light-emitting elements 131 and a plurality of optical sensing elements 132, which are not limited. The light-emitting element 131 emits a light to the outer ear canal. When the light is reflected by the external auditory canal or the light is diffracted by the external auditory canal, the optical sensing element 132 can be received by the optical sensing component 132. Measurement The signal SS, and the sensing signal SS is a light volume change signal. As the pulse of the human body is generated, the blood flow of the systemic blood vessels also changes, and the content of hemoglobin and deoxyhemoglobin in the blood vessels also changes. Among them, hemoglobin and deoxyhemoglobin have relatively sensitive characteristics (for example, red light, infrared light or green light) for light of a specific wavelength, so if the light-emitting element 131 (such as a light-emitting diode) emits red light, infrared light Light or green light (red light wavelength range 622 ~ 770nm, infrared light wavelength range 771 ~ 2500nm, green light wavelength range 492 ~ 577nm) to the tissues and blood vessels under the skin of the external auditory canal, and then optical sense The measuring element 132 (such as the photosensitive element) receives the light that reflects or penetrates the skin, and the intensity of the received blood is transmitted through the received light, and the change is called a photoplethysmography (PPG). PPG is a physical quantity produced by the blood circulation system. When the heart is contracting and relaxing, the blood flow per unit area of the blood vessel causes periodic changes. Since the PPG signal change is caused by the heart beat, the degree of light energy of the reflected or diffracted light received by the optical sensing element 132 can correspond to the pulse. Therefore, the changes in the pulse and blood oxygen concentration of the human body and the physiological information related to the ear canal can be measured through the ear canal type measuring device 1.
另外，由於外耳道的表面並不是平順的表面，而且也不是規則的形狀，其尺寸更是因人而異，不過，每個人的外耳道都具有一共同特性，即是具有一彎折部(圖未顯示)。因此，在本實施例中，感測模組13的位置係對應於外耳道之彎折部，藉此，使感測模組13可正確量測到所要的生理參數。 In addition, since the surface of the external auditory canal is not a smooth surface, and it is not a regular shape, its size varies from person to person. However, each person's external auditory canal has a common characteristic, that is, it has a bent portion (Fig. display). Therefore, in the embodiment, the position of the sensing module 13 corresponds to the bending portion of the external auditory canal, thereby enabling the sensing module 13 to accurately measure the desired physiological parameter.
另外，請參照圖2A至圖2C所示，其分別為圖1A之耳道式量測裝置1配戴於不同尺寸的外耳道之示意圖。於此，圖2A之耳道式量測裝置1係配戴於較小尺寸的外耳道，圖2B之耳道式量測裝置1係配戴於一般尺寸的外耳道，而圖2C之耳道式量測裝置1係配戴於較大尺寸的外耳道。 In addition, please refer to FIG. 2A to FIG. 2C , which are schematic diagrams of the ear canal measuring device 1 of FIG. 1A being worn on different sizes of external auditory canal. Here, the ear canal type measuring device 1 of FIG. 2A is worn on the outer ear canal of a smaller size, and the ear canal type measuring device 1 of FIG. 2B is worn on the external ear canal of a general size, and the ear canal type of FIG. 2C is used. The measuring device 1 is worn on a larger outer ear canal.
如圖2A所示，由於可變機構12之彈性件122具有彈性，且不受壓力時會往外側翹地而頂抵於耳塞墊121，因此，當耳道式量測裝置1配戴於較小尺寸的外耳道，外耳道將提供一力量F1透過耳塞墊121而壓迫彈性件122，使彈性件122產生一往外側的彈性回復力，並透過彈性件122往外側之彈性回復力而使耳塞墊121與外耳道緊密地貼合。 As shown in FIG. 2A, since the elastic member 122 of the variable mechanism 12 has elasticity and is biased outwardly against the earplug pad 121 when it is not under pressure, when the ear canal type measuring device 1 is worn In the small-sized external auditory canal, the external auditory canal provides a force F1 through the earplug pad 121 to press the elastic member 122, so that the elastic member 122 generates an elastic restoring force to the outside, and the elastic restoring force to the outside through the elastic member 122 causes the earplug pad 121 Closely fits the external auditory canal.
另外，如圖2B所示，當耳道式量測裝置1配戴於一般尺寸的外耳道時，外耳道一樣可提供一力量F2(F2<F1)透過耳塞墊121而壓迫彈性件122，彈性件122一樣也會產生一往外側的彈性回復力，並透過彈性件122往外側之彈性回復力而使耳塞墊121可與外耳道緊密地貼合。 In addition, as shown in FIG. 2B, when the ear canal measuring device 1 is worn on the external ear canal of a general size, the external auditory canal can provide a force F2 (F2 < F1) through the ear pad 121 to press the elastic member 122, and the elastic member 122. Similarly, an elastic restoring force to the outside is generated, and the elastic restoring force of the elastic member 122 to the outside allows the earplug pad 121 to closely fit the external auditory canal.
此外，如圖2C所示，當耳道式量測裝置1配戴於較大尺寸的外耳道時，外耳道一樣會提供一力量F3(F3<F2<F1)透過耳塞墊121而壓迫彈性件122，彈性件122也會產生一往外側的彈性回復力(只是比較小)，並透過彈性件122往外側之彈性回復力而使耳塞墊121可與外耳道緊密地貼合。因此，耳道式量測裝置1可藉由彈性件122產生一向外的彈性回復力，使可變機構12之耳塞墊121可緊密地貼合於不同大小尺寸外耳道之皮膚表面。當不同使用者配戴耳道式量測裝置1進行活動時(例如運動)，耳道式量測裝置1也不會因震動、鬆脫而造成漏光，因此，與習知相較，本發明不僅適合於不同使用者的耳道而具有配戴舒適的優點，更可避免運動時所產生的漏光現象所造成的生理訊號量測上的誤差。 In addition, as shown in FIG. 2C, when the ear canal measuring device 1 is worn on a large-sized external auditory canal, the external auditory canal provides a force F3 (F3 < F2 < F1) through the ear pad 121 to press the elastic member 122. The elastic member 122 also produces an elastic restoring force to the outside (only relatively small), and the elastic restoring force of the elastic member 122 to the outside allows the earplug pad 121 to closely fit the external auditory canal. Therefore, the ear canal measuring device 1 can generate an outward elastic restoring force by the elastic member 122, so that the earplug pad 121 of the variable mechanism 12 can be closely attached to the skin surface of the external ear canal of different sizes. When different users wear the ear canal type measuring device 1 to perform activities (for example, exercise), the ear canal type measuring device 1 does not cause light leakage due to vibration and looseness, and therefore, compared with the prior art, the present invention It not only fits the ear canal of different users, but also has the advantage of wearing comfort, and can avoid the error of physiological signal measurement caused by the light leakage phenomenon generated during exercise.
請再參照圖1A及1B所示，聲音模組14設置於耳機本體11內，並與控制模組15電性連接。其中，聲音模組14具有一聲音處理元件及一揚聲器，當耳道式量測裝置1連接於一音樂播放器時，聲音模組14可輸出音樂，使配戴者可一邊活動一邊聽音樂，使耳道式量測裝置1具有一般耳機的功能。 Referring to FIG. 1A and FIG. 1B , the sound module 14 is disposed in the earphone body 11 and electrically connected to the control module 15 . The sound module 14 has a sound processing component and a speaker. When the ear canal measuring device 1 is connected to a music player, the sound module 14 can output music, so that the wearer can listen to music while playing.

The variable mechanism 12 is detachably connected to the earphone body 11c. Here, the earphone body 11c has a protruding portion 111, and the variable mechanism 12c has a hook portion 124, and the protruding portion 111 is disposed corresponding to the hook portion 124. In other words, the user can select an ear boot (variable mechanism 12c) suitable for the size of his or her ear canal, and attach the ear boot (variable mechanism 12c) to the earphone body 11c. Wherein, when the variable mechanism 12c is attached, the hook portion 124 can be correspondingly engaged with the protruding portion 111. Therefore, when different users wear the ear canal type measuring device 1c for activities (for example, exercise), since the variable mechanism 12c suitable for the external auditory canal is selected, light leakage due to vibration and looseness is not caused, therefore, the ear The road type measuring device 1c not only has the advantage of wearing comfort, but also avoids the error in the measurement of the physiological signal caused by the light leakage phenomenon generated during the movement.
