Abstract
Description
本發明係有關一種電極之技術,特別是指一種軟式之感應電極。 The present invention relates to a technique for an electrode, and more particularly to a soft sensing electrode.
按,隨著醫療技術演進,眾多人體密碼隨之破解,而生理訊號亦可輕易的被偵測到而讓醫生進一步瞭解患者的身體狀況,例如偵測心電訊號輸出心電圖,可依據心跳週期頻率推測患者的心臟是否健康;偵測肌電訊號輸出肌電圖,可依據波形推測患者的肌肉、神經系統甚至小腦是否有問題;而偵測腦波訊號則是測量大腦皮質的電流,可藉由腦部的生理變化判斷患者的意識、情緒等狀態或是昏迷、中風、癲癇、腦炎、和其他腦疾病病人的追蹤。 According to the evolution of medical technology, many human body passwords are cracked, and physiological signals can be easily detected to allow doctors to further understand the patient's physical condition, such as detecting ECG output ECG, according to the heartbeat cycle frequency. Predict whether the patient's heart is healthy; detect the EMG output EMG, can predict whether the patient's muscles, nervous system or even the cerebellum have problems according to the waveform; and detect the brain wave signal is to measure the current of the cerebral cortex, by Physiological changes in the brain determine the patient's consciousness, mood, etc., or the tracking of patients with coma, stroke, epilepsy, encephalitis, and other brain diseases.
目前偵測生理訊號的電極多為濕式電極,將電極片黏貼、吸附在身體上,再於電極片上夾上金屬夾便可偵測到生理訊號,如檢查心電圖時所使用的黏貼式電極;但若欲偵測腦波則麻煩的多,因為頭皮上被頭髮覆蓋,頭髮不同於體表的毛髮,較粗又茂密,不但黏貼式電極難以貼在頭皮上,隔著頭髮也不易導電,若不將頭髮剃掉,便需在電極片上塗抹導電膠以幫助導電,除了準備時間冗長並有可能造成頭皮傷害外,一般導電膠只要半小時就會乾掉,因此每測量半小時就需補充導電膠,常使檢測者滿頭膠水;另有一種乾式電極,其為一長寬在1.5公分內的立方體,不需要導電膠幫助導電,但用在量測腦波時仍會受頭髮干擾而影響量測結果。 At present, the electrodes for detecting physiological signals are mostly wet electrodes, and the electrode sheets are adhered and adsorbed on the body, and then the metal clips are clamped on the electrode sheets to detect physiological signals, such as the adhesive electrodes used for checking the electrocardiogram; However, if you want to detect brain waves, it is much more troublesome. Because the scalp is covered with hair, the hair is different from the body surface. It is thick and dense. It is difficult to stick the electrode on the scalp, and it is not easy to conduct electricity through the hair. If the hair is not shaved, it is necessary to apply conductive adhesive on the electrode sheet to help conduct electricity. In addition to the long preparation time and possible damage to the scalp, the conductive glue will dry out in half an hour, so the conductive adhesive needs to be added every half hour. It often makes the tester full of glue; there is also a dry electrode, which is a cube with a length and width of 1.5 cm. It does not need conductive glue to help conduct electricity, but it is still affected by hair interference when measuring brain waves. Test results.
有鑑於此,本發明遂針對上述習知技術之缺失,提出一種感應電極,以有效克服上述之該等問題。 In view of the above, the present invention has been directed to the absence of the above-mentioned prior art, and proposes an inductive electrode to effectively overcome the above problems.
本發明之主要目的在提供一種感應電極,其係利用軟式的針狀電極接觸皮膚,如頭皮,且柔軟的軟性探針可將頭髮排開,不需將頭髮剃掉亦不需塗抹導電膠,便可直接接觸頭皮感測腦波,且其軟性材質也對頭皮有好的保護作用。 SUMMARY OF THE INVENTION The main object of the present invention is to provide a sensing electrode which uses a soft needle electrode to contact the skin, such as the scalp, and a soft soft probe for arranging the hair without shaving or applying conductive glue. It can directly touch the scalp to sense brain waves, and its soft material also has a good protective effect on the scalp.
本發明之另一目的在提供一種感應電極,其底座及軟性探針通體導電,且軟性探針可彎曲以增加與皮膚的接觸面積,不只有探針的尖端可感應生理訊號。 Another object of the present invention is to provide an induction electrode in which the base and the soft probe are electrically conductive, and the soft probe is bendable to increase the contact area with the skin, and not only the tip of the probe can sense physiological signals.
為達上述之目的,本發明提供一種感應電極,包含一底座及複數軟性探針,軟性探針直立於底座之一面,感測至少一生理訊號並透過底座傳遞出去。當感應電極貼近皮膚進行感測時,利用軟性探針的材質特性可將毛髮排開、探針彎曲接觸皮膚而感測到生理訊號,可避免毛髮阻隔影響感測效果。 To achieve the above object, the present invention provides a sensing electrode comprising a base and a plurality of soft probes, the soft probe standing on one side of the base, sensing at least one physiological signal and transmitting through the base. When the sensing electrode is close to the skin for sensing, the material characteristics of the soft probe can be used to separate the hair and the probe is bent into contact with the skin to sense the physiological signal, thereby preventing the hair barrier from affecting the sensing effect.

In this embodiment, there are five soft probes 14, each of which has the same length and thickness.
影響探針對於生理訊號接收機率的因素包含接觸面積、阻抗及導電率等,底座12及軟性探針14皆為軟性、導電材質,其材質舉例而言可為混合銀玻璃的矽膠,阻抗低;底座12及軟性探針14係一體成型,其製造方法係利用熱壓模成型或射出成型方式。 The factors affecting the rate of the probe for the physiological signal include the contact area, the impedance and the conductivity. The base 12 and the soft probe 14 are both soft and conductive materials, and the material thereof can be, for example, a silicone glass mixed with a low impedance; The base 12 and the soft probe 14 are integrally molded, and the manufacturing method is a hot press molding or an injection molding method.
在第1圖之實施例中,軟性探針14係與底座12互相垂直,且軟性探針14為直條;第3圖為本發明感應電極10之另一實施例,在此實施例中軟性探針14的頂端向外彎曲擴張,更有利於將頭髮排開。 In the embodiment of FIG. 1, the soft probe 14 is perpendicular to the base 12, and the soft probe 14 is a straight strip; and FIG. 3 is another embodiment of the sensing electrode 10 of the present invention, which is soft in this embodiment. The tip end of the probe 14 is outwardly curved and expanded to facilitate the discharge of the hair.
當應用本發明之感應電極貼近皮膚進行感測時,可將複數個感應電極裝設在量測腦波的腦波帽上,或是量測其他生理訊號的儀器上,軟性探針接觸皮膚後,其柔軟的材質特性會使軟性探針的頂端因壓力而彎曲,藉以將周圍的毛髮排開,進而在皮膚表面感測到生理訊號,如心電訊號、腦波訊號或肌電訊號等,避免毛髮阻隔影響感測效果,將完整清晰的訊號傳送到量測儀器中。另外軟性探針的軟性材質也對頭皮有好的保護作用。 When the sensing electrode of the present invention is applied to the skin for sensing, a plurality of sensing electrodes may be mounted on a brain wave cap for measuring brain waves, or an instrument for measuring other physiological signals, and the soft probe contacts the skin. The soft material properties cause the tip of the soft probe to bend due to pressure, thereby arranging the surrounding hair and sensing physiological signals such as electrocardiogram, brain wave signal or myoelectric signal on the skin surface.
