本發明係有關於一種子宮收縮檢測方法，特別係有關於依據加速度判斷子宮收縮狀況是否正常之子宮收縮檢測方法。
The invention relates to a method for detecting uterine contraction, in particular to a method for detecting uterine contraction according to whether the uterus contraction condition is normal according to the acceleration.
在現代社會中，由於人們晚婚或是不婚的情況逐漸增加，使得少子化的現象日漸嚴重，對國家的人口結構有著極大的影像，目前少子化問題已經成為現今已開發國家的政府必須極積面對的一個社會問題。當然的，也有許多家庭是因為夫妻中有一人因為生活壓力過於龐大而患有***症造成懷孕困難，在現代社會中這樣的家庭也並非少數，也進而加重了少子化的現象。In modern society, due to the gradual increase of people's late marriage or non-marriage, the phenomenon of declining birthrate is becoming more and more serious, and there is a great image of the country's population structure. At present, the problem of minority birth has become a must for the governments of developed countries. A social problem facing. Of course, there are also many families because one of the couples has difficulty in pregnancy because of the excessive pressure of life and infertility. In modern society, such a family is not a minority, which in turn increases the phenomenon of declining birthrate.
對於一個家庭而言，妻子懷有身孕無疑的是一件值得高興的事情，尤其是包含有家人的期待與祝福的孩子在出生的那一刻，更是代表著一個家庭即將開始嶄新生活，夫妻也會在此時轉換成父母的身分，通常來說不易懷孕的家庭若是渴望孩子的話就會嘗試各種方法，例如說使用人工受孕、誘導***或是試管嬰兒等方式來提高懷孕的機會。For a family, it is a happy thing for a wife to be pregnant. Especially the child who has the expectation and blessing of the family at the moment of birth, it means that a family is about to start a new life. At this time, it will be converted into the identity of the parents. Generally speaking, families who are not easy to get pregnant will try various methods if they are eager for the child, for example, using artificial conception, induction of ovulation or test-tube baby to improve the chance of pregnancy.
這些不容易懷孕的家庭一旦有了孩子，便一定會希望自己的小孩能夠平安的出生，絕對不會讓這得來不易的孩子有任何的疏失或是意外。If these children are not easy to get pregnant, they will hope that their children will be born safely, and will never let the hard-won children have any mistakes or accidents.
但根據早產兒基金會的統計，早產的機率僅佔所有新生兒比例的5%至10%，但早產兒的死亡率卻占了新生兒死亡比例的八成以上，此外，近年來嬰兒胎死腹中的病例也越來越多，尤其是高齡產婦更是容易發生上述的狀況。However, according to the statistics of the Premature Infants Foundation, the prevalence rate is only 5% to 10% of all newborns, but the mortality rate of premature infants accounts for more than 80% of neonatal deaths. In addition, in recent years, infants have died. There are more and more cases, especially in older women.
對於有上述風險的產婦而言，可能會因為胎兒著床位置不好或是其他因素造成子宮有些微的收縮，但是因為這種感覺與想上廁所的感覺非常類似也有可能因為懷孕後期的肚子較為緊繃而被忽略，常使得產婦誤解了身體所提出的警告沒有前往醫院就診，當此子宮持續的微量收縮，會使得子宮內胎兒的心跳發生異常而造成早產甚至是胎死腹中，造成無法彌補的遺憾。產婦若是在子宮異常收縮時能馬上到醫院進行檢查及治療，即可避免上述的危險。但是子宮的異常收縮是一種間歇性的動作，沒有一定的規律及週期性，醫院中的醫療器材雖然可以準確地提供檢查結果，但是卻不能提供先前子宮異常收縮的數據及出院後的追蹤。For women who have the above risks, the uterus may be slightly contracted due to poor fetal implantation or other factors, but because this feeling is very similar to the feeling of going to the toilet, it may be because the stomach is later in pregnancy. Tight and neglected, often causing the mother to misunderstand the warnings given by the body without going to the hospital for treatment. When the uterus continues to shrink, the heartbeat of the uterus will be abnormal and cause premature birth or even fetal death. Make up for the regrets. If the woman can go to the hospital for examination and treatment immediately when the uterus is abnormally contracted, the above danger can be avoided. However, the abnormal contraction of the uterus is an intermittent movement. Without certain regularity and periodicity, the medical equipment in the hospital can accurately provide the examination results, but it cannot provide the data of the abnormal uterine contraction and the follow-up after discharge.
為了不影響孕婦的生活作息，且又能兼顧到孕婦及胎兒安全，最好是有一種可以適用於移動式裝置的偵測子宮收縮狀況及記錄子宮收縮狀況，並能夠透過現有的紀錄來分析子宮是否有異常的收縮產生之方法，如此，孕婦能夠藉由此方法於家中自行檢測子宮收縮是否異常，以達到早期預警的效果，並且能在下次產檢時或是因為其他狀況進入醫院時，能夠提供相關的數據給醫生做為參考，以獲得更好的醫療品質，亦可在每月的產檢間隔期間可以提供孕婦更多參考與保障。In order not to affect the life of pregnant women, but also to take into account the safety of pregnant women and the fetus, it is best to have a mobile device to detect uterine contractions and record uterine contractions, and to analyze the uterus through existing records. Is there an abnormal method of contraction, so that pregnant women can use this method to detect abnormal uterine contractions at home to achieve early warning effects, and can provide them at the next check-up or when they enter the hospital due to other conditions. Relevant data can be used as a reference for doctors to obtain better medical quality, and more reference and protection for pregnant women can be provided during the monthly inspection interval.

Referring to the second drawing, it is a schematic view showing the detection method of the uterine contraction detecting method according to the first embodiment of the present invention. As shown in the figure, the detection method of the uterine contraction detecting method of the present invention is to place a mobile device 30 on a user 10, wherein the mobile device 30 has an acceleration sensor 301, a processing unit 303 and a database. 305. The mobile device 30 is placed on the abdomen of the user 10. Since the uterus is located in the center of the lower abdomen of the woman, the optimal position of the mobile device 30 is directly below the navel 101 of the user 10, and can also be tied. The mobile device 30 is fixed directly under the navel 101 of the user 10 with a fixing device such as a belt, and the user 10 is in a state of standing and lying flat during measurement. The mobile device 30 described above may be a smart phone, a personal digital assistant (PDA), and a tablet or other mobile device with an acceleration sensor. The database 305 stores at least one uterine contraction status information, which may be accumulated by the user 10 during daily measurement, or may be a pre-entered pattern or other According to the uterus contraction status information obtained by the method, the at least one uterine contraction condition information has a corresponding threshold interval number and a threshold interval duration, wherein the database 305 is not limited to the mobile device 30, or is disposed in the mobile device 30 Externally connected to the database 305 by the mobile device 30 via wireless or wired to obtain uterine contraction status information.
於此說明本發明之第一實施例之子宮收縮檢測方法執行時之流程，請參閱第一圖、第二A圖、第二B圖及第二C圖，該使用者10欲以本發明之子宮收縮檢測方法檢測子宮收縮狀況時，先進行步驟ST1，該使用者10處於靜置平躺之狀態時放置該移動式裝置30於該使用者10之肚臍101正下方，此時，該移動式裝置30之X軸方向是由該使用者10的右側指向左側，該移動式裝置30之Y軸方向是由該使用者10的頭頂指向腳底。接著執行步驟ST3，該移動式裝置30內之該加速度感測器301產生複數加速度訊號，該些加速度訊號分別包含一X軸加速度訊號及一Y軸加速度訊號。Herein, the flow of the uterine contraction detecting method according to the first embodiment of the present invention is described. Referring to the first drawing, the second A drawing, the second B drawing, and the second C drawing, the user 10 intends to use the present invention. When the uterine contraction detecting method detects the uterus contraction condition, step ST1 is performed first, and the user 10 is placed in a state of standing and lying down, and the mobile device 30 is placed directly below the navel 101 of the user 10, at this time, the mobile type The X-axis direction of the device 30 is directed to the left by the right side of the user 10, and the Y-axis direction of the mobile device 30 is directed from the top of the user 10 to the sole of the foot. Then, the acceleration sensor 301 in the mobile device 30 generates a plurality of acceleration signals, and the acceleration signals respectively include an X-axis acceleration signal and a Y-axis acceleration signal.
接續上述，執行步驟ST5，該移動式裝置30內之該處理單元303設定該些加速度訊號中第一個加速度訊號為一基準訊號，也就是說該基準訊號為該加速度感測器301所產生的第一個加速度訊號。再來執行步驟ST7，該處理單元303將該些加速度訊號分別與該基準訊號進行向量內積運算取得複數加速度變化量。當該加速度感測器301產生五個加速度訊號(AS，Acceleration Signal)分別為AS 0(X 0,Y 0)、AS 1(X 1,Y 1)、AS 2(X 2,Y 2)、AS 3(X 3,Y 3)及AS 4(X 4,Y 4)時，第一組加速度訊號AS 0(X 0,Y 0)會被該處理單元303設定為基準訊號(BS，Base Signal)BS(BX,BY)，第二至第五組加速度訊號則分別與基準訊號進行向量內積運算，其公式為： Continuing the above, in step ST5, the processing unit 303 in the mobile device 30 sets the first acceleration signal of the acceleration signals as a reference signal, that is, the reference signal is generated by the acceleration sensor 301. The first acceleration signal. Then, in step ST7, the processing unit 303 performs a vector inner product calculation on the acceleration signals and the reference signal to obtain a complex acceleration change amount. When the acceleration sensor 301 generates five acceleration signals (AS, Acceleration Signal), respectively, AS 0 (X 0 , Y 0 ), AS 1 (X 1 , Y 1 ), AS 2 (X 2 , Y 2 ), When AS 3 (X 3 , Y 3 ) and AS 4 (X 4 , Y 4 ), the first set of acceleration signals AS 0 (X 0 , Y 0 ) are set as reference signals by the processing unit 303 (BS, Base Signal) BS(BX, BY), the second to fifth sets of acceleration signals are respectively subjected to a vector inner product operation with the reference signal, and the formula is:
其中i表示第i組加速度訊號。經運算後取得加速度變化量C1、C2、C3及C4。
Where i represents the i-th set of acceleration signals. The acceleration change amounts C1, C2, C3, and C4 are obtained after the calculation.
接續上述，在取得該些加速度變化量後執行步驟ST9，判斷該些加速度變化量是否持續符合一門檻區間。子宮收縮會在一段時內持續的發生，因此該些加速度變化量要持續的符合該門檻區間才有可能是因為加速度感測器301感測到子宮收縮而產生的加速度訊號。其中，該門檻區間有一門檻區間之下限值及一門檻區間之上限值。於本實施例中該門檻區間之下限值為1g，該門檻區間之上限值為1.2g，此下限值及上限值是於實驗中量測子宮收縮狀況所取得之數值，亦有可能隨著所使用之加速度感測器的靈敏度而有所差異，且加速度變化量要符合該門檻區間達10秒以上才會被認定為是子宮收縮，也就是加速度變化量必須要是連續不間斷的大於該門檻區間之下限值並小於該門檻區間之上限值，以藉此防避免有其他因素(例如有人碰觸到該移動式裝置30)造成的加速度瞬間改變被視為子宮收縮。Following the above, after obtaining the acceleration change amounts, step ST9 is executed to determine whether the acceleration change amounts continue to meet a threshold interval. The uterine contraction will continue to occur for a period of time, so the amount of acceleration change that continues to meet the threshold interval is likely due to the acceleration signal generated by the acceleration sensor 301 sensing the contraction of the uterus. Wherein, the threshold interval has a threshold lower limit value and a threshold interval upper limit value. In the present embodiment, the lower limit of the threshold interval is 1 g, and the upper limit of the threshold interval is 1.2 g. The lower limit value and the upper limit value are values obtained by measuring the uterine contraction condition in the experiment, and also It may vary with the sensitivity of the accelerometer used, and the amount of acceleration change must be consistent with the threshold interval for more than 10 seconds to be considered uterine contraction, that is, the amount of acceleration change must be continuously uninterrupted. An upper limit value greater than the threshold interval and less than the upper limit of the threshold interval, thereby preventing an instantaneous change in acceleration caused by other factors (such as a person touching the mobile device 30) is regarded as uterine contraction.
接續上述，當該些加速度變化量持續符合該門檻區間後，表示該加速度感測器301有感測到子宮收縮所產生的加速度值，接著執行步驟ST11，該處理單元303依據一門檻區間次數及一門檻區間持續時間比對該資料庫305取得收縮狀況資訊。該處理單元303計算該門檻區間次數及該門檻區間持續時間，並與該資料庫305中的資料進行比對，取得符合該門檻區間次數及該門檻區間持續時間的收縮狀況。其中該門檻區間次數是表示在一段時間裡該些加速度變化量連續符合該門檻區間的次數，如第二C圖中該門檻區間次數為二次，該門檻區間次數更可用以其他方式表示，例如說在十分鐘內出現五次、出現頻率是0.008Hz或是每分鐘0.5次(0.5bpm)等。該門檻持續時間是表示每次有連續符該門檻區間的加速度變化量的持續時間，如第二C圖所示，該門檻持續時間可以用分、秒等時間單位來表示，如持續60秒；更可以用一個持續區間來表示，如持續50秒~60秒；亦可以用每次持續時間是否變化量過大表示，例如第一次持續時間為60秒第二次持續時間為55秒第三次持續時間為62秒，每次持續時間變化量在10秒內則變化量未過大，又例如第一次持續時間為40秒第二次持續時間為25秒第三次持續時間為10秒，每次持續時間變化量超過15秒則變化量過大。Continuing the above, when the acceleration change amount continues to meet the threshold interval, it indicates that the acceleration sensor 301 senses the acceleration value generated by the uterus contraction, and then proceeds to step ST11, and the processing unit 303 determines the number of intervals according to a threshold interval. A threshold interval duration information is obtained for the database 305. The processing unit 303 calculates the threshold interval and the threshold interval duration, and compares the data in the database 305 to obtain a contraction condition that matches the threshold interval and the threshold interval duration. The number of the threshold intervals is the number of times the acceleration changes continuously meet the threshold interval in a period of time. For example, the number of the threshold intervals in the second C diagram is twice, and the number of the threshold intervals can be expressed in other manners, for example, It is said that it appears five times in ten minutes, the frequency of occurrence is 0.008 Hz or 0.5 times per minute (0.5 bpm). The threshold duration is a duration indicating an amount of acceleration change of the threshold interval each time. As shown in FIG. C, the threshold duration may be expressed in units of time, such as minutes and seconds, for example, for 60 seconds; It can be expressed by a continuous interval, such as 50 seconds to 60 seconds; it can also be expressed by whether the duration is too large, for example, the first duration is 60 seconds, the second duration is 55 seconds, and the third time. The duration is 62 seconds, and the amount of change in each duration is less than 10 seconds. For example, the first duration is 40 seconds, the second duration is 25 seconds, and the third duration is 10 seconds. If the amount of change in the subduration exceeds 15 seconds, the amount of change is too large.
舉例而言，正常收縮(Normal Contraction)的子宮收縮狀況資訊為該門檻區間次數為十分鐘5次及該門檻區持續時間為60秒，當該些加速度變化量符合正常收縮的子宮收縮狀況資訊所對應的該門檻區間次數及該門檻區間隔時間時，該處理單元303從該資料庫取得目前收縮狀況為正常收縮；高滲收縮(Hypertnic Contraction)的子宮收縮狀況資訊為該門檻區間次數為十分鐘內大於5次及該門檻區間隔時間為20秒，當該些加速度變化量符合高滲收縮的子宮收縮狀況資訊所對應的該門檻區間次數及該門檻區間隔持續時，該處理單元303從該資料庫取得目前收縮狀況為高滲收縮；低滲收縮(Hypotonic Contraction)的子宮收縮狀況資訊為該門檻區間次數為十分鐘內小於5次及該門檻區持續時間變化量過大，當該些加速度變化量符合低滲收縮的子宮收縮狀況資訊所對應的該門檻區間次數及該門檻區持續時間時，該處理單元303從該資料庫305取得目前收縮狀況為低滲收縮。For example, the normal contraction uterus contraction status information is that the threshold interval is 10 minutes and the threshold time is 60 seconds, when the acceleration changes in accordance with the normal contraction of the uterine contraction information Corresponding to the number of the threshold interval and the interval between the thresholds, the processing unit 303 obtains the current contraction condition from the database as a normal contraction; the hypertrophic contraction (Uypertnic Contraction) uterine contraction status information indicates that the threshold interval is ten minutes. The processing unit 303 is configured to be greater than 5 times and the interval time of the threshold region is 20 seconds. When the acceleration change amount corresponds to the number of the threshold interval corresponding to the hyperosmolar uterus contraction condition information and the threshold interval continues, the processing unit 303 The current state of contraction is hyperosmolar; the uterine contraction status of hypotonic contraction is that the threshold interval is less than 5 times within ten minutes and the duration of the threshold is too large, when the acceleration changes The number of thresholds corresponding to the amount of uterine contraction information in accordance with hypotonic contraction and the threshold At the time of the zone duration, the processing unit 303 obtains from the database 305 that the current contraction condition is hypotonic contraction.
最後執行步驟ST13，輸出收縮狀況資訊，該處理單元303輸出於步驟ST11中所取得的收縮狀況資訊，收縮狀況資訊可顯示於移動式裝置30之顯示單元上。於此步驟完成後即完成本發明之第一實施例之子宮收縮檢測方法，任一孕婦皆可以自身所持有之移動式裝置於家中先行檢測目前的子宮收縮狀況，並藉由移動式裝置上所顯示之子宮收縮狀況資訊判斷目前子宮收縮狀況是否異常來決定是否前往醫院，而不用每一次有子宮收縮時都急急忙忙前往醫院就診。Finally, step ST13 is executed to output the contraction status information. The processing unit 303 outputs the contraction status information obtained in step ST11, and the contraction status information can be displayed on the display unit of the mobile device 30. After the completion of this step, the uterine contraction detecting method of the first embodiment of the present invention is completed, and any pregnant woman can detect the current uterine contraction condition at home by using the mobile device held by herself, and by using the mobile device. The displayed uterine contraction status information determines whether the current uterine contraction condition is abnormal to decide whether to go to the hospital, instead of rushing to the hospital every time there is uterine contraction.
在第一實施例中已提及本發明可用於檢測子宮收縮的狀況，而在懷孕的過程中子宮亦有可能產生除了收縮以外的異常狀況，此異常狀況依然可以使用本發明之方法來偵測。It has been mentioned in the first embodiment that the present invention can be used to detect a condition of uterine contraction, and during the course of pregnancy, the uterus may also generate abnormal conditions other than contraction, which can still be detected using the method of the present invention. .
在此說明本發明之第二實施例之子宮收縮檢測方法之流程圖，本發明之第二實施例可同時運用於偵測子宮收縮的狀況及子宮異常狀況，請參閱第三A圖、第三B圖及第三C圖，其係本發明之第二實施例之子宮收縮檢測方法之流程圖。如圖所示，本實施例與第一實施例之差異在於步驟ST9替換為步驟ST901：判斷加速度變化量是否持續符合門檻區間，若否，則執行步驟ST10：判斷加速度變化量是持續大於還是持續小於門檻區間，當加速度變化量持續大於門檻區間時執行步驟ST101，當加速度變化量持續大於門檻區間時執行步驟ST103。若是，則後續步驟與第一實施例相同，於此不再贅述。Here, a flow chart of the uterine contraction detecting method according to the second embodiment of the present invention will be described. The second embodiment of the present invention can be simultaneously applied to detect the condition of uterine contraction and the abnormal state of the uterus. Please refer to the third A and third figures. B and 3C are flowcharts of the uterine contraction detecting method of the second embodiment of the present invention. As shown in the figure, the difference between this embodiment and the first embodiment is that step ST9 is replaced with step ST901: determining whether the acceleration change amount continues to meet the threshold interval, and if not, executing step ST10: determining whether the acceleration change amount is continuously greater or longer. If the amount of acceleration change continues to be greater than the threshold interval, step ST101 is performed, and when the amount of acceleration change continues to be greater than the threshold interval, step ST103 is performed. If yes, the subsequent steps are the same as those in the first embodiment, and details are not described herein again.
當於步驟ST9時該處理單元303判斷加速度變化量並未持續符合該門檻區間時則執行步驟ST10，判斷該些加速度變化量是持續大於還是持續小於門檻區間。當該處理單元303判斷該些加速度變化量大於該門檻區間之上限值並持續一段時間時即代表目前處於飽和刺激(Saturated Stimulation)的子宮異常狀態，此時執行步驟ST101，該處理單元303輸出一第一異常狀況資訊並顯示於移動式裝置之顯示單元上，該第一異常狀況資訊表示目前子宮處於飽和刺激。When the processing unit 303 determines in step ST9 that the acceleration change amount does not continue to meet the threshold interval, step ST10 is performed to determine whether the acceleration change amount is continuously greater than or continues to be less than the threshold interval. When the processing unit 303 determines that the acceleration change amount is greater than the upper limit of the threshold interval and continues for a period of time, it represents a uterus abnormal state that is currently in a saturated stimulus. At this time, step ST101 is performed, and the processing unit 303 outputs A first abnormal condition information is displayed on the display unit of the mobile device, and the first abnormal condition information indicates that the current uterus is in a saturated stimulus.
接續上述，當於步驟ST10中，當該處理單元303判斷該些加速度變化量小於該門檻區間之下限值並持續一段時間時即代表目前處於不規則收縮(Contraction Stimulation)的子宮異常狀態，此時執行步驟ST103，該處理單元303輸出一第二異常狀況資訊並顯示於移動式裝置之顯示單元上，該第二異常狀況資訊表示目前子宮處於不規則收縮。其中，更可以加入一異常狀況門檻值，當該些加速度變化量大於該異常狀況門檻值時，才進一步的判斷該些加速度變化量是否小於該門檻區間之下限值並持續一段時間。Following the above, when the processing unit 303 determines that the acceleration change amount is less than the lower limit of the threshold interval and continues for a period of time, it represents the abnormal state of the uterus which is currently in the contraction stimulation. When the step ST103 is executed, the processing unit 303 outputs a second abnormal condition information and displays it on the display unit of the mobile device, and the second abnormal condition information indicates that the uterus is in an irregular contraction. Wherein, an abnormal condition threshold value may be added. When the acceleration change amount is greater than the abnormal condition threshold value, it is further determined whether the acceleration change amount is less than the lower limit value of the threshold interval and continues for a period of time.
上述為本發明之第二實施例之子宮收縮檢測方法，任一孕婦皆可以自身所持有之移動式裝置於家中先行檢測目前的子宮收縮狀況，並藉由移動式裝置上所顯示之子宮收縮狀況資訊判斷目前子宮收縮狀況是否異常來決定是否前往醫院，而不用每一次有子宮收縮時都急急忙忙前往醫院就診。According to the uterine contraction detecting method of the second embodiment of the present invention, any pregnant woman can detect the current uterine contraction condition at home by the mobile device held by herself, and the uterus contraction displayed on the mobile device The status information determines whether the current uterine contraction condition is abnormal to decide whether to go to the hospital, instead of rushing to the hospital every time there is uterine contraction.
本發明是使用加速度的變化量來判別子宮收縮狀態，然而目前的醫學文獻多是以壓力的變化量來表示子宮的收縮狀況，本發明之方法亦可依據目前醫學文獻中用來表示子宮收縮狀況壓力的變化量來判斷子宮收縮的狀況，以下將詳細說明。The present invention uses the amount of change in acceleration to determine the uterine contraction state. However, the current medical literature mostly refers to the contraction state of the uterus by the amount of change in pressure. The method of the present invention can also be used to indicate the uterine contraction state according to the current medical literature. The amount of change in pressure is used to determine the condition of uterine contraction, which will be described in detail below.
在此說明本發明之第三實施例之子宮收縮檢測方法之流程圖，本發明之第三實施例是運用於依據目前醫學文獻中用來表示子宮收縮狀況壓力的變化量來偵測子宮收縮的狀況及子宮異常狀況，請參閱第四圖，其係本發明之第三實施例之子宮收縮檢測方法之流程圖。如圖所示，本實施例與第二實施例之差異在於步驟ST7之後與步驟ST901之前更有一步驟ST8：取得校準加速度變化量，將該些加速度變化量輸入一回歸方程式(Equation of Regression)中，該回歸方程式會輸出複數校正後加速度變化量，並於後續步驟中都以該些校正後加速度變化量取代該些加速度變化量。該回歸方程式是將以本發明之子宮收縮檢測方法所檢測到的加速度變化量與目前醫學文獻中所記載的壓力變化量經由迴歸分析(Regression Analysis)後取得。其中迴歸分析可依據實際使用需求選用簡單線性迴歸(simple linear regression)、複迴歸分析(multiple regression analysis)及對數線性迴歸(Log-linear model)等。Here, a flow chart of a uterine contraction detecting method according to a third embodiment of the present invention is described, and a third embodiment of the present invention is applied to detect uterine contraction based on the amount of change in the pressure of the uterus contraction state in the current medical literature. For the condition and uterine abnormality, please refer to the fourth figure, which is a flow chart of the uterine contraction detecting method according to the third embodiment of the present invention. As shown in the figure, the difference between this embodiment and the second embodiment is that after step ST7 and before step ST901, there is a step ST8: obtaining a calibration acceleration change amount, and inputting the acceleration change amounts into an equation of regression (Equation of Regression) The regression equation outputs the complex corrected acceleration change amount, and replaces the acceleration change amounts with the corrected acceleration change amounts in subsequent steps. This regression equation is obtained by regression analysis (Regression Analysis) of the amount of change in acceleration detected by the uterine contraction detecting method of the present invention and the amount of pressure change described in the current medical literature. Among them, regression analysis can be based on simple linear regression, multiple regression analysis and log-linear model.
於步驟ST8完成後在接著執行步驟ST901至ST13，待執行完成後即完成本發明之第三實施例之子宮收縮檢測方法，任一孕婦皆可以自身所持有之移動式裝置於家中先行檢測目前的子宮收縮狀況，並藉由移動式裝置上所顯示之子宮收縮狀況資訊判斷目前子宮收縮狀況是否異常來決定是否前往醫院，而不用每一次有子宮收縮時都急急忙忙前往醫院就診。After the completion of step ST8, steps ST901 to ST13 are subsequently performed, and after the completion of the execution, the uterine contraction detection method of the third embodiment of the present invention is completed, and any pregnant woman can first detect the current at home by the mobile device held by herself. The uterus contraction condition, and whether the current uterine contraction condition is abnormal by the uterus contraction status information displayed on the mobile device determines whether to go to the hospital, instead of rushing to the hospital every time there is uterine contraction.
本發明是使用加速度的變化量來判別子宮收縮狀態，然而於檢測時孕婦會有翻身、移動或是其他狀況使得移動式裝置30移動時，該加速度感測器301所感測到的X軸加速度及Y軸加速度跟著發生變化，此時兩軸的加速度變化量就會包含子宮收縮時的加速度及該移動式裝置30移動時的加速度，為此需要降低該移動式裝置30在移動時對檢測所造成的影響，以下將詳細說明。The present invention uses the amount of change in acceleration to determine the uterine contraction state. However, when the pregnant woman has a turn-over, movement or other condition during the detection, the X-axis acceleration sensed by the acceleration sensor 301 and The acceleration of the Y-axis changes accordingly. At this time, the amount of acceleration change of the two axes includes the acceleration when the uterus contracts and the acceleration when the mobile device 30 moves. For this reason, it is necessary to reduce the detection caused by the mobile device 30 when moving. The impact will be described in detail below.
在此說明本發明之第四實施例之子宮收縮檢測方法之流程圖，本發明之第四實施例是運用在該使用者10於翻身、移動或是其他狀況使得移動式裝置30移動時，請參閱第五圖，其係本發明之第四實施例之子宮收縮檢測方法之流程圖，其中Z軸方向是由該使用者10的前側指向後側。如圖所示，本實施例與第三實施例之差異在於步驟ST5之後與步驟ST7之前更有一步驟ST6：判斷基準訊號之該Z軸加速度訊號與每一該些加速度訊號之Z軸加速度訊號進行相減其差值是否大於Z軸變化量門檻值，若是，則執行步驟ST601，重新設定基準訊號，該處理單元設定該加速度訊號為一新基準訊號；若否，則執行步驟ST7。Z軸加速度除了於Z軸感測到的加速度外，更會包含X軸及Y軸的加速度，因此以Z軸加速度為依據在基準訊號之Z軸加速度訊號與該些加速度訊號的Z軸加速度訊號的差值大於一Z軸變化量門檻值時，將此加速度訊號設定為基準訊號。其中，該Z軸變化量門檻值為1.5，該Z軸變化量門檻值為依據文獻所提及的子宮收縮的正常與異常時所產生的壓力最大值轉換成加速度值後所取得，換句話說就是無論在正常或異常的收縮狀況，皆不會產生大於此Z軸變化量門檻值的加速度。亦可於視實際使用需求將該Z軸變化量門檻值降低，以使得重新設定基準訊號的靈敏度提升。本實施例其餘部分與第三實施例相同，於此不再贅述。Here, a flow chart of a uterine contraction detecting method according to a fourth embodiment of the present invention is described. The fourth embodiment of the present invention is applied when the user 10 moves, moves or otherwise causes the mobile device 30 to move. Referring to Fig. 5, a flowchart of a uterine contraction detecting method according to a fourth embodiment of the present invention, wherein the Z-axis direction is directed to the rear side by the front side of the user 10. As shown in the figure, the difference between this embodiment and the third embodiment is that after step ST5 and before step ST7, there is a step ST6: determining the Z-axis acceleration signal of the reference signal and the Z-axis acceleration signal of each of the acceleration signals. If the difference is greater than the threshold value of the Z-axis change amount, if yes, step ST601 is executed to reset the reference signal, and the processing unit sets the acceleration signal as a new reference signal; if not, step ST7 is performed. In addition to the acceleration sensed by the Z-axis, the Z-axis acceleration also includes the accelerations of the X-axis and the Y-axis. Therefore, the Z-axis acceleration signal of the reference signal and the Z-axis acceleration signal of the acceleration signals based on the Z-axis acceleration are used. When the difference is greater than a Z-axis change threshold, the acceleration signal is set as the reference signal. Wherein, the threshold value of the Z-axis variation is 1.5, and the threshold value of the Z-axis variation is obtained by converting the maximum value of the pressure generated by the normal and abnormal uterine contractions mentioned in the literature into an acceleration value, in other words, That is, no acceleration greater than the threshold of the Z-axis change is generated regardless of the normal or abnormal contraction condition. The Z-axis variation threshold may also be lowered depending on actual usage requirements, so that the sensitivity of resetting the reference signal is increased. The rest of the embodiment is the same as the third embodiment, and details are not described herein again.
舉例而言，有五組加速度訊號(X 0,Y 0,Z 0)、(X 1,Y 1,Z 1)、(X 2,Y 2,Z 2)、(X 3,Y 3,Z 3)及(X 4,Y 4,Z 4)，第一組加速度訊號(X 0,Y 0,Z 0)被該處理單元303設定為基準訊號(BX,BY,BZ)。(X 1,Y 1,Z 1)及(X 2,Y 2,Z 2)兩組加速度訊號的Z軸加速度Z 1和Z 2與基準訊號的Z軸加速度BZ相減的差值不超過該Z軸變化量門檻值，因此不重新設定基準訊號，繼續執行步驟ST7，以(X 1,Y 1,Z 1)及(X 2,Y 2,Z 2)的X軸加速度和Y軸加速度分別與(BX,BY,BZ)也就是(X 0,Y 0,Z 0)的X軸加速度與Y軸加速度進行向量內積運算取得加速度變化量。而(X 3,Y 3,Z 3)之加速度訊號的Z軸加速度Z 3與基準訊號的Z軸加速度BZ相減的差值超過該Z軸變化量門檻值，此時執行步驟ST601該處理單元303重新設定(X 3,Y 3,Z 3)這組加速度訊號為基準訊號(BX,BY,BZ)，而下一組加速度訊號(X 4,Y 4,Z 4)則是與新的基準訊號(BX,BY,BZ)也就是(X 3,Y 3,Z 3)進行比較Z軸變化與計算加速度變化量。 For example, there are five sets of acceleration signals (X 0 , Y 0 , Z 0 ), (X 1 , Y 1 , Z 1 ), (X 2 , Y 2 , Z 2 ), (X 3 , Y 3 , Z 3 ) and (X 4 , Y 4 , Z 4 ), the first set of acceleration signals (X 0 , Y 0 , Z 0 ) are set by the processing unit 303 as reference signals (BX, BY, BZ). (X 1 , Y 1 , Z 1 ) and (X 2 , Y 2 , Z 2 ) The difference between the Z-axis accelerations Z 1 and Z 2 of the two sets of acceleration signals and the Z-axis acceleration BZ of the reference signal does not exceed The Z-axis change amount threshold value, so the reference signal is not reset, and step ST7 is continued to perform the X-axis acceleration and the Y-axis acceleration of (X 1 , Y 1 , Z 1 ) and (X 2 , Y 2 , Z 2 ), respectively. The vector internal product operation is performed with (XX, BY, BZ), that is, (X 0 , Y 0 , Z 0 ), and the acceleration of the acceleration is obtained by performing a vector inner product calculation. The difference between the Z-axis acceleration Z 3 of the acceleration signal of (X 3 , Y 3 , Z 3 ) and the Z-axis acceleration BZ of the reference signal exceeds the threshold value of the Z-axis variation, and the processing unit of step ST601 is executed. 303 reset (X 3 , Y 3 , Z 3 ) This set of acceleration signals is the reference signal (BX, BY, BZ), and the next set of acceleration signals (X 4 , Y 4 , Z 4 ) is the new reference The signal (BX, BY, BZ) is also (X 3 , Y 3 , Z 3 ) to compare the Z-axis variation with the calculated acceleration variation.

Hurry to the hospital.

接著說明本發明之第五實施例之子宮收縮檢測方法執行時之流程，請參閱第二A圖、第二B圖、第七圖、第八A圖、第八B圖及第八C圖，該使用者10欲以本發明之子宮收縮檢測方法檢測子宮收縮狀況時，先進行步驟ST21，該使用者10處於靜置平躺之狀態時放置該移動式裝置30於該使用者10之肚臍101正下方。接著執行步驟ST23，該移動式裝置30內之該加速度感測器301產生複數加速度訊號，該些加速度訊號分別包含一X軸加速度訊號及一Y軸加速度訊號。Next, the flow of the uterine contraction detecting method according to the fifth embodiment of the present invention will be described. Please refer to the second A diagram, the second B diagram, the seventh diagram, the eighth A diagram, the eighth B diagram, and the eighth C diagram. When the user 10 wants to detect the uterus contraction condition by the uterine contraction detecting method of the present invention, the first step ST21 is performed, and the user 10 is placed in the state of standing and lying down to place the mobile device 30 on the navel 101 of the user 10. Directly below. Then, in step ST23, the acceleration sensor 301 in the mobile device 30 generates a plurality of acceleration signals, and the acceleration signals respectively include an X-axis acceleration signal and a Y-axis acceleration signal.
接續上述，執行步驟ST25，該移動式裝置30內之該處理單元303設定該些加速度訊號中第一個加速度訊號為一基準訊號。繼續執行步驟ST27，判斷基準訊號之該Z軸加速度訊號與每一該些加速度訊號之Z軸加速度訊號進行相減其差值是否大於Z軸變化量門檻值，若是，則執行步驟ST2701，重新設定基準訊號，該處理單元設定該加速度訊號為一新基準訊號；若否，則執行步驟ST9。於步驟ST29中，該處理單元303將該些加速度訊號分別與該基準訊號進行向量內積運算取得複數加速度變化量。In the above step, the processing unit 303 in the mobile device 30 sets the first acceleration signal of the acceleration signals as a reference signal. Continuing to step ST27, it is determined whether the Z-axis acceleration signal of the reference signal is subtracted from the Z-axis acceleration signal of each of the acceleration signals by a difference between the Z-axis acceleration signal and the Z-axis change threshold. If yes, step ST2701 is performed to reset. The reference signal, the processing unit sets the acceleration signal as a new reference signal; if not, step ST9 is performed. In step ST29, the processing unit 303 performs a vector inner product calculation on the acceleration signals and the reference signal to obtain a complex acceleration change amount.
接續上述，在取得該些加速度變化量後執行步驟ST211，取得收縮強度值，該處理單元將該些個加速度變化量分別轉換成複數個收縮強度值，其轉換公式為：Following the above, after obtaining the acceleration change amounts, step ST211 is performed to obtain a contraction intensity value, and the processing unit converts the plurality of acceleration change amounts into a plurality of contraction intensity values, respectively, and the conversion formula is:
其中I為收縮強度值，
為一第一常數，
為一第二常數，Da為該基準訊號與一原點座標(0,0)之夾角，Sa為該些個加速度變化量。
Where I is the contraction strength value, Is a first constant, Is a second constant, Da is the angle between the reference signal and an origin coordinate (0, 0), and Sa is the acceleration change amount.
該第一常數C1及該第二常數C2會隨著該加速度感測器301之靈敏度而改變。該基準訊號與該原點座標(0,0)之夾角之算法可用利公式：The first constant C1 and the second constant C2 change with the sensitivity of the acceleration sensor 301. The algorithm for the angle between the reference signal and the origin coordinate (0, 0) can be used in the following formula:
以找出該基準訊號與該原點座標之夾角。其中，當量測時該基準訊號與該原點座標相同時Da會等於零，因ln(0)為無意義數，此時會請使用重新調整該移動式裝置30的位置已重新設定該基準訊號。
To find the angle between the reference signal and the origin coordinate. Wherein, when the reference signal is the same as the origin coordinate in the equivalent measurement, Da will be equal to zero, because ln(0) is a meaningless number, and the position of the mobile device 30 has been reset to reset the reference signal. .
接著執行步驟ST213，判斷該些收縮強度值是否持續符合一門檻區間。如第八A圖所示，子宮收縮會在一段時內持續的發生，因此該些收縮強度值要持續的符合該門檻區間才有可能是因為加速度感測器301感測到子宮收縮而產生的收縮強度值。其中，該門檻區間有一門檻區間之下限值及一門檻區間之上限值。於本實施例中該門檻區間之下限值為30mmHg，該門檻區間之上限值為40mmHg，且加速度變化量要符合該門檻區間達10秒以上才會被認定為是子宮收縮，也就是加速度變化量必須要是連續不間斷的大於該門檻區間之下限值並小於該門檻區間之上限值。Next, step ST213 is executed to determine whether the contraction strength values continue to meet a threshold interval. As shown in FIG. 8A, the uterine contraction will continue to occur for a period of time, so that the contraction strength values are consistently consistent with the threshold interval because the acceleration sensor 301 senses the contraction of the uterus. Contraction strength value. Wherein, the threshold interval has a threshold lower limit value and a threshold interval upper limit value. In this embodiment, the lower limit of the threshold interval is 30 mmHg, and the upper limit of the threshold interval is 40 mmHg, and the acceleration change amount is equal to the threshold interval for more than 10 seconds to be regarded as uterine contraction, that is, acceleration. The amount of change must be continuously uninterrupted greater than the lower limit of the threshold interval and less than the upper limit of the threshold interval.
當於步驟ST213時該處理單元303判斷加速度變化量並未持續符合該門檻區間時則執行步驟ST215，判斷該些收縮強度值是持續大於還是持續小於門檻區間。如第八B圖所示，當該處理單元303判斷該些收縮強度值大於該門檻區間之上限值並持續一段時間時即代表目前處於飽和刺激(Saturated Stimulation)的子宮異常狀態，此時執行步驟ST2151，該處理單元303輸出一第一異常狀況資訊並顯示於移動式裝置之顯示單元上，該第一異常狀況資訊表示目前子宮處於飽和刺激。When the processing unit 303 determines in step ST213 that the acceleration change amount does not continue to meet the threshold interval, step ST215 is performed to determine whether the contraction intensity values are continuously greater than or continuously less than the threshold interval. As shown in FIG. 8B, when the processing unit 303 determines that the contraction intensity values are greater than the upper limit of the threshold interval and continues for a period of time, it represents a uterus abnormal state currently in a saturated stimulation, and is performed at this time. In step ST2151, the processing unit 303 outputs a first abnormal condition information and displays it on the display unit of the mobile device, and the first abnormal condition information indicates that the current uterus is in a saturated stimulus.
接續上述，當於步驟ST213中，如第八C圖所示，當該處理單元303判斷該些收縮強度值小於該門檻區間之下限值並持續一段時間時即代表目前處於不規則收縮(Contraction Stimulation)的子宮異常狀態，此時執行步驟ST2153，該處理單元303輸出一第二異常狀況資訊並顯示於移動式裝置之顯示單元上，該第二異常狀況資訊表示目前子宮處於不規則收縮。其中，更可以加入一異常狀況門檻值，當該些加速度變化量大於該異常狀況門檻值時，才進一步的判斷該些加速度變化量是否小於該門檻區間之下限值並持續一段時間。Following the above, in step ST213, as shown in the eighth C diagram, when the processing unit 303 determines that the contraction intensity values are less than the lower limit of the threshold interval and continues for a period of time, it represents that the current contraction is irregular (Contraction Stimulation uterus abnormal state, at this time step ST2153 is executed, the processing unit 303 outputs a second abnormal condition information and is displayed on the display unit of the mobile device, the second abnormal condition information indicating that the uterus is currently in irregular contraction. Wherein, an abnormal condition threshold value may be added. When the acceleration change amount is greater than the abnormal condition threshold value, it is further determined whether the acceleration change amount is less than the lower limit value of the threshold interval and continues for a period of time.
接續上述，於步驟ST213中當該些收縮強度值持續符合該門檻區間後，表示該加速度感測器301有感測到子宮收縮所產生的加速度值，接著執行步驟ST217，該處理單元303依據一門檻區間次數及一門檻區間持續時間比對該資料庫305取得收縮狀況資訊。該處理單元303計算該門檻區間次數及該門檻區間持續時間，並與該資料庫305中的資料進行比對，取得符合該門檻區間次數及該門檻區間持續時間的收縮狀況。Following the above, in step ST213, after the contraction intensity values continue to meet the threshold interval, it indicates that the acceleration sensor 301 senses the acceleration value generated by the uterus contraction, and then proceeds to step ST217, the processing unit 303 according to The threshold interval number and the threshold interval duration ratio are obtained for the database 305. The processing unit 303 calculates the threshold interval and the threshold interval duration, and compares the data in the database 305 to obtain a contraction condition that matches the threshold interval and the threshold interval duration.
最後執行步驟ST219，輸出收縮狀況資訊，該處理單元303輸出於步驟ST217中所取得的收縮狀況資訊，收縮狀況資訊可顯示於移動式裝置30之顯示單元上。於此步驟完成後即完成本發明之第五實施例之子宮收縮檢測方法，於本實施例加速度變化量會被轉換為收縮強度值，可以讓使用者及醫療人員更直接的判斷收縮狀況。Finally, step ST219 is executed to output the contraction status information, and the processing unit 303 outputs the contraction status information acquired in step ST217, and the contraction status information can be displayed on the display unit of the mobile device 30. After the completion of this step, the uterine contraction detecting method of the fifth embodiment of the present invention is completed. In this embodiment, the amount of acceleration change is converted into a contraction strength value, which allows the user and the medical staff to more directly judge the contraction condition.
