Description
本創作關於一種負壓式睡眠呼吸中止治療裝置的消音結構。 The present invention relates to a sound absorbing structure of a negative pressure sleep breathing abortion treatment device.
睡眠呼吸中止(Obstructive Sleep Apnea,OSA)、呼吸不足(hypopnea)及上呼吸道阻塞徵候群(Upper Airway Resistance Syndrome,UARS)係在睡眠期間、麻醉期間或者麻醉後因上呼吸道完全或部份阻塞所引起的各種症狀,它們會造成睡眠期間呼吸中斷而潛藏著嚴重的血液中缺氧的危機。OSA,呼吸不足及/或UARS的患者會因為睡眠期間氧氣不足而經常地重覆被喚醒,導致片斷性睡眠及不良的睡眠品質。 Obstructive Sleep Apnea (OSA), hypopnea (Hypernea), and Upper Airway Resistance Syndrome (UARS) are caused by complete or partial obstruction of the upper respiratory tract during sleep, during anesthesia, or after anesthesia. A variety of symptoms, they can cause a disruption of breathing during sleep and a serious crisis of hypoxia in the blood. Patients with OSA, hypopnea and/or UARS are often repeatedly awakened due to insufficient oxygen during sleep, resulting in fragmental sleep and poor sleep quality.
對於睡眠呼吸中止症狀患者最普遍治療方法是採用正壓呼吸器(Constant Positive Airway Pressure(CPAP)Machine)。正壓呼吸器係由面罩、幫浦及濕潤機組成。正壓呼吸器係連續地將高壓空氣吹入患者鼻道,以使患者在睡眠期間保持呼吸道暢通。正壓呼吸器相當有效,但它會引起令人不舒服的副作用,例如喉嚨乾燥及鼻道阻塞。使用正壓呼吸器的患者經常會在早晨感到腫脹及頭疼。由於它引起的嚴重副作用使得它具有低的適應性。 The most common treatment for patients with sleep-disordered breathing is the use of a Constant Positive Airway Pressure (CPAP) Machine. Positive pressure breathing apparatus consists of a mask, a pump and a humidifier. The positive pressure respirator continuously blows high pressure air into the patient's nasal passages to keep the patient's airway clear during sleep. Positive pressure respirators are quite effective, but they can cause unpleasant side effects such as dry throat and blocked nasal passages. Patients who use positive pressure respirators often experience swelling and headaches in the morning. It has low adaptability due to the serious side effects it causes.
另一種治療方法是在患者口腔內施予負壓,利用負壓通入使用者口腔前端,通常是在唇部或唇部稍後方,藉由負壓將舌頭拉向前方,以拉提舌頭的後端遠離呼吸道背面。採用口腔負壓的口部裝置通常使用真空幫浦提供真空源,但真空幫浦運轉時產生的 噪音往往干擾患者的睡眠,使得如何降噪成為採用負壓式睡眠呼吸中止治療裝置需要解決的一項課題。 Another treatment method is to apply a negative pressure in the patient's mouth, and use a negative pressure to pass into the front end of the user's mouth, usually at the back of the lip or lip, and pull the tongue forward by negative pressure to pull the tongue out. The back end is away from the back of the respiratory tract. Oral devices that use negative oral pressure typically use a vacuum pump to provide a vacuum source, but when the vacuum pump is running Noise often interferes with the patient's sleep, making noise reduction a problem that needs to be solved with a negative pressure sleep breathing therapy device.
