201216922 六、發明說明： 【發明所屬之技術領域】 [0001] 本發明係有關於一種可攜式手持裝置，其係尤指一 種可偵測生理狀態之可攜式手持裝置。 【先前技術】 [0002] 按，心率變異度（Heart Rate Var iabi 1 i ty， HRV)的心率是指心臟跳動的頻率，單位是BPM (Beat Per Minute)，是由1 981年Akse 1 rod發表，其藉由非 侵入的方式量測並紀錄心電訊號，在經過快速傅立葉轉 〇 換以求得心率變異特性的功率頻譜；而變異度則是每個 心跳時間間格上的差距，亦即心臟跳動的頻率與心跳時 間間格上的程度變化。心率變異度之特性功率頻譜可以 對應出自主神經系統之生理作用機制。長時間HRV的高低 變化可以反應一個人的自律神經是否失調，也可以反應 出心臟功能的健康情形。 自主神經系統屬於周邊神經系統的一部份，它控制 身體内器官的功能，自主神經系統分為兩類：交感和副 〇 ^ 交感神經系統。交感神經系統在有壓力的時候其活動占 優勢，所產生的效應讓身體預備在面對壓力反應時做出 動作。它的效用是為身體消耗能量；而副交感系統則是 在休息及靜養時其活動占優勢，所產生的效應會加速及 調節諸如消化和生長的過程。為了讓身體能休息及靜養 ，它的活動可用來保存能量。 目前評估自主神經系統活動最有效的方法就是心率 變異度（HRV )之分析。HRV特性會由交感與副交感神經 系統交互作用與調控產生變異，所以醫學上常藉由心率 099136818 表單編號A0101 第3頁/共18頁 0992064311-0 201216922 變異來研究自主神經系統的調節情形。因此由心率變異 度的高低，即可得知一個人的自主神經是否失調，而心 率變異度亦可反應心臟功能的健康，其低變異度代表著 高心臟病危險性。因此藉由心率變異特性可作為多項疾 病判斷或治療之徵兆，例如心律不整、糖尿病、憂鬱症 等。 「心律不整」是指心跳不正常，亦即心跳間隔長短 不同，而心跳的頻率過快或過慢時也算是心律不整，例 如心跳頻率比正常快的「頻脈」或是心跳頻率比正常慢 的「徐脈」。除了某些心臟本身有疾病時會發生心律不 整之情形外，因呼吸有所變動時亦會發生心律不整之情 形；例如一個人深深吸氣時心跳會加快，而把氣吐出來 時心跳就會慢下來，這是正常的生理現象。此外如運動 時心跳會加快，而休息或睡覺時心跳則會變慢，另外如 自主神經系統的興奮、咖啡或茶的刺激、發燒、緊張、 壓力過大、疼痛、缺氧、藥物等等，都可能使心跳速率 及節律有所改變。 心律不整時，從毫無症狀到有一些輕微症狀如：感 覺心跳加快，或是感覺到不規則的心跳；當心律不整嚴 重時，會引起病人休克、昏倒甚至猝死。不少猝死病患 平時並無任何徵候，即使年輕人也可能發生。醫學界現 在認為，除了藉由過去病例分析外，可藉由心率變異度 之突然降低作為疾病的預測指標。尤其是經常忙碌的人 ，經由長期心率變異度的監控，若發現HRV偏低或逐漸降 低，則應立刻休息，可減少猝死之機率。 HRV亦可作為糖尿病（D1 abetes)之治療效果的判斷 099136818 表單編號A0101 第4頁/共18頁 0992064311-0 201216922 。糖尿病患初期，在血糖雖維持正常範圍内，但HRV已逐 漸下降。而中期及末期的糖尿病患可能併發神經壞死症 (Diabetic Neuropathy)，此時交感及副交感之細小 纖維開始壞死，病人會出現站立眩暈（低血壓）、心悸、 盜汗、及肚瀉等自律神經失調症狀。經由長期量測HRV， 會發現HRV偏離原有之基準線，治療效果也可依此判斷。 另外，HRV$可判斷憂餐症（Depression)的發病 。憂鬱症是一種醫學疾病，不僅僅是「情緒沮喪」而已 。每年有上千萬的人患上這種疾病；婦女患有憂#症的 〇 可能性是男性的兩倍。患有其他疾病，比如心臟病、中 風、癌症及糖尿病的患者病發憂鬱症的機率更高。而這 些病患的HRV在量測上通常顯現活性偏低之情形。文獻顯 示許多西醫處方藥可以改善憂鬱症狀。據估計，80%至 90%的憂鬱症患者可以經專業的藥物療法和心理療法而 痊癒。若長期利用HRV的量測來追蹤療效，則可更快使憂 營症疾癒。 若要獲得HRV的資訊，不需要分析整個心電圖的細節 ® ，只要能取得心跳的間期，就能由心跳間期分析而得到 。測量HRV是需要一段時間，約十分鐘以上，沒辦法在短 時間内知道結果。量測的方法，首先需要找到心電訊號 的心跳間期，然後經過重新取樣，把取樣後的資料經過 快速傅立葉轉換，即可求得心律變異的功率頻譜，從心 率變異的功率頻譜可以得到高頻（0. 15-0. 4Hz)和低頻 (0. 04-0. 15Hz)的功率，由高低頻功率的變化可以當 作自律神經活性的指標。 接上所述，現今有一種脈動感測技術是一種非侵入 099136818 表單編號A0101 第5頁/共18頁 0992064311-0 201216922 式偵測組織内血管床血量變化的光學計量技術，而一般 採用穿透式與反射式兩種型態的感測探頭，運用不同光 源與光感測器組合以擷取血液脈動生理訊號。穿透式脈 動感測器的機構設計中，光源與感測器分別在受測組織 的兩端，必須選擇可穿透光的身體部位來進行檢測。通 常感測探頭是以鉗夾手指、耳朵、或鼻子等可穿透部位 來進行檢測，光源也需選擇穿透組織能力較強的光波長 作為光源。反射式的探頭設計是將光源與感測器放置於 同一側的方式來檢測，可在身體任一部位進行檢測。其 設計上必須考慮不同待測部位的組織光學性質，並選擇 適當光源波長與適當的功率，才能偵測到進入組織再從 組織反射回來的脈動訊號。 然而，現今之脈動感測裝置都相當笨重，若需要進 行量測時，必須在醫院或是相關的醫療院所進行量測， 如此，造成民眾相當地不便。 因此，如何針對上述問題而提出一種新穎可偵測生 理狀態之可攜式手持裝置，其可隨時進行量測，而避免 造成民眾的不便，使可解決上述之問題。 【發明内容】 [0003] 099136818 本發明之目的之一，在於提供一種可偵測生理狀態 之可攜式手持裝置，其將一脈動感測模組與一可攜式手 持裝置連接，而讓使用者可隨時進行量測，進而增加使 用方便性。 本發明之目的之一，在於提供一種可偵測生理狀態 之可攜式手持裝置，其藉由一訊號轉換單元轉換一脈動 感測模組所產生之一感測訊號為一音頻訊號，而可減少 表單編號A0101 第6頁/共18頁 0992064311-0 201216922201216922 VI. Description of the Invention: [Technical Field] [0001] The present invention relates to a portable handheld device, and more particularly to a portable handheld device capable of detecting a physiological state. [Prior Art] [0002] Heart Rate Var iabi 1 ty (HRV) heart rate refers to the frequency of heart beat, in BPM (Beat Per Minute), published by Akse 1 rod in 1981 By measuring and recording the ECG signal in a non-invasive manner, the fast power Fourier transform is used to obtain the power spectrum of the heart rate variability characteristic; and the variability is the gap between each heartbeat time, that is, The degree of change in the frequency of heart beats and heartbeat time. The characteristic power spectrum of heart rate variability can correspond to the physiological mechanism of the autonomic nervous system. The high and low changes of HRV for a long time can reflect whether a person's autonomic nerve is out of tune, and can also reflect the health of heart function. The autonomic nervous system is part of the peripheral nervous system. It controls the function of organs in the body. The autonomic nervous system is divided into two categories: sympathetic and parasympathetic ^ sympathetic nervous system. The sympathetic nervous system prevails when it is stressed, and the resulting effects prepare the body to act in the face of stress. Its utility is to consume energy for the body; while the parasympathetic system prevails during rest and rest, and the effects that accelerate and regulate processes such as digestion and growth. In order to allow the body to rest and rest, its activities can be used to conserve energy. The most effective method for assessing autonomic nervous system activity is the analysis of heart rate variability (HRV). The HRV characteristics are mutated by the interaction and regulation of the sympathetic and parasympathetic nervous systems. Therefore, the regulation of the autonomic nervous system is often studied by heart rate 099136818 Form No. A0101 Page 3 / 18 pages 0992064311-0 201216922 Variation. Therefore, from the level of heart rate variability, it can be known whether a person's autonomic nerve is out of tune, and heart rate variability can also reflect the health of heart function, and its low variability represents a high risk of heart disease. Therefore, heart rate variability can be used as a symptom of multiple disease judgments or treatments, such as arrhythmia, diabetes, depression, and the like. "Arrhythmia" means that the heartbeat is not normal, that is, the heartbeat interval is different. When the heartbeat frequency is too fast or too slow, it can be regarded as arrhythmia. For example, the heartbeat frequency is faster than normal, or the heartbeat frequency is slower than normal. "Xu Mai". In addition to some cases where the heart itself has a disease, arrhythmia may occur. When the breathing changes, arrhythmia may occur. For example, when a person inhales deeply, the heart beats faster, and when the gas is spit out, the heart beats. Slow down, this is a normal physiological phenomenon. In addition, the heart rate will increase when exercising, and the heartbeat will slow down during rest or sleep. In addition, the excitement of the autonomic nervous system, coffee or tea stimulation, fever, nervousness, stress, pain, hypoxia, drugs, etc. It may change the heart rate and rhythm. When the heart rhythm is not complete, from no symptoms to some mild symptoms such as: feeling a rapid heartbeat, or feeling an irregular heartbeat; when the heart rhythm is not serious, it may cause the patient to shock, faint or even drown. Many sudden death patients usually have no signs, even young people may occur. The medical profession now believes that, in addition to past case analysis, a sudden decrease in heart rate variability can be used as a predictor of disease. Especially for people who are busy, after monitoring the long-term heart rate variability, if the HRV is found to be low or gradually reduced, it should be rested immediately, which can reduce the chance of sudden death. HRV can also be used as a judgment for the therapeutic effect of diabetes (D1 abetes). 099136818 Form No. A0101 Page 4 of 18 0992064311-0 201216922. In the early stage of diabetes, although the blood sugar remained within the normal range, the HRV has gradually decreased. In the middle and late stages of diabetes, Diabetic Neuropathy may be complicated. At this time, the sympathetic and parasympathetic fine fibers begin to necrosis, and patients may experience symptoms such as standing vertigo (hypotension), palpitations, night sweats, and diarrhea. . After long-term measurement of HRV, it will be found that HRV deviates from the original baseline, and the treatment effect can be judged accordingly. In addition, HRV$ can determine the onset of Depression. Depression is a medical condition, not just "emotional depression." Tens of millions of people suffer from this disease every year; women are twice as likely as men to suffer from anxiety. People with other diseases, such as heart disease, stroke, cancer and diabetes, have a higher chance of developing depression. The HRV of these patients usually shows a low activity in the measurement. The literature shows that many Western medicine prescription drugs can improve depression symptoms. It is estimated that 80% to 90% of people with depression can be cured by professional drug therapy and psychotherapy. If you use HRV measurements to track the long-term effects, you can make your ailments worse. To get HRV information, you don't need to analyze the details of the entire ECG ® , as long as you can get the heartbeat interval, you can get it from the heartbeat interval analysis. Measuring HRV takes a while, about ten minutes or more, and there is no way to know the result in a short time. The measurement method first needs to find the heartbeat interval of the ECG signal, and then after re-sampling, the sampled data is subjected to fast Fourier transform to obtain the power spectrum of the heart rate variation, and the power spectrum from the heart rate variation can be obtained high. The power of the frequency (0. 15-0. 4Hz) and the low frequency (0. 04-0. 15Hz) can be regarded as an indicator of autonomic nerve activity by the change of high and low frequency power. In addition, there is a pulsation sensing technology which is a non-invasive 099136818 Form No. A0101 Page 5 / 18 pages 0992064311-0 201216922 An optical metrology technique for detecting changes in blood volume of a vascular bed in a tissue, and generally wears Transmissive and reflective two types of sensing probes use different light sources combined with light sensors to extract blood pulsation physiological signals. In the mechanism design of the penetrating pulsation sensor, the light source and the sensor are respectively at the two ends of the tested tissue, and the body part that can penetrate the light must be selected for detection. Generally, the sensing probe is detected by clamping a penetrating portion such as a finger, an ear, or a nose, and the light source also needs to select a light wavelength that has a strong penetrating ability as a light source. The reflective probe design is designed to place the light source and sensor on the same side and can be detected at any part of the body. It must be designed in consideration of the tissue optical properties of different parts to be tested, and the appropriate source wavelength and appropriate power can be selected to detect the pulsation signal that enters the tissue and is reflected back from the tissue. However, today's pulsation sensing devices are quite cumbersome. If they need to be measured, they must be measured in a hospital or a related medical institution. This is quite inconvenient for the people. Therefore, how to solve the above problem is to provide a novel portable device capable of detecting a physiological state, which can be measured at any time without being inconvenienced by the public, so that the above problems can be solved. SUMMARY OF THE INVENTION [0003] One of the objects of the present invention is to provide a portable handheld device capable of detecting a physiological state, which connects a pulsation sensing module to a portable handheld device for use. Measurements can be made at any time to increase ease of use. One of the objects of the present invention is to provide a portable handheld device capable of detecting a physiological state, wherein a sensing signal generated by a signal conversion module is converted into an audio signal by a signal conversion unit.
