使用本發明之呼吸器時，氣瓶21是處於開啟狀，並 供應氣體使供氣管路22内維持一定的氣壓源。但在手動按 壓件374未被按壓之下，由於栓塞件373的阻隔，使氣體 流道33呈一阻斷狀態，患者不會吸入氣體。俟手動按壓件 374被按壓後，氣體流道33始呈一開通狀態，氣體會流經 背壓室32後再流通至第一閥體部411，閥片42袁氣體壓力) 作用下免開启欠使氣體流通至面ϋ „，以供患者吸入氣暴。但 當患者吐出之氣體流通至第二閥體部412後，關片42 Α — 反向壓力作用工if j，使氣體無至敗复既第二411 ，而從氣體旁通道417排出至外部。 此外，當背壓室32内之氣體壓力大於第一彈性元件 382施加於球塞381的頂推力時，則球塞381受背壓室32 内之氣壓驅動，而朝限流元件343方向產生位移，使背壓 室32内過高的氣壓經由泡壓通道34及浪射L 344被釋出 ，直到背壓室32内之氣體壓力與第—彈性元件如施加於 球塞381的頂推力相同時，球塞381藉由第一彈性元件382 的頂推力而抵接於大、小孔徑部341、342相鄰處形成之肩 部345而封閉舰通道34，使f壓室32内之氣體無法排出 至外部。因此，藉由㈣閥38的配置，背壓室32内之氣 壓能維持-定值，使患者能安全地在均—氣壓下接受治療 Ο 9 1285121 、 由於患者吸氣及吐氣之氣體交換動作主要發生在單向 • 閥4内，且在本實施例中單向閥4是一可拋棄式閥體，所 以，當下個患者在使用時便不用擔心衛生上的顧慮。又， 患者吐出之氣體藉由閥片42的擋止不會流通至控制閥3, 因此患者口中吐出之飛沫及細菌便不會殘留於控制閥3内 ，使控制閥3方便清潔。值得一提的是，單向閥4也可為 重覆使用式的閥體，並不受限於本實施例所揭露。 ·· 歸納上述，本發明之呼吸器，藉由可拋棄式單向閥4 的配置，使患者吸氣及吐氣之氣體交換動作主要發生在單 向閥4内，患者吐出之氣體會由單包閥4排出至外部而不 會流通至控制閥3，對控制閥3造成污染，使控制閥3方便 清潔，因此下個使用的患者不用擔心衛生安全上的顧慮， 故確實能達到本發明所訴求之目的。 惟以上所述者’僅為本發明之較佳實施例而已，當不 能以此限定本發明實施之範圍，即大凡依本發明申請專利 • 範圍及發明說明内容所作之簡單的等效變化與修飾，皆仍 屬本發明專利涵蓋之範圍内。 【圖式簡單說明】 圖1是一習知呼吸器之分解示意圖； 圖2是本發明呼吸器之較佳實施例之一分解示意圖； 圖3是該較佳實施例之一控制閥的上視圖； 圖4是圖3沿IV_IV方向之一剖視圖，說明一手動開關 單元未受觸壓時的狀態； 圖5是一類似圖4之視圖，說明該手動開關單元受觸 10 1285121 ^ 壓時的狀態；及 圖6是該較佳實施例之一單向閥的分解圖。 11 1285121 【主要元件符號說明】When the respirator of the present invention is used, the gas cylinder 21 is in an open state, and the supply of gas maintains a certain source of pressure in the gas supply line 22. However, when the manual pressing member 374 is not pressed, the gas flow path 33 is in a blocked state due to the blocking of the plug member 373, and the patient does not inhale the gas. After the manual pressing member 374 is pressed, the gas flow path 33 starts to be in an open state, and the gas flows through the back pressure chamber 32 and then flows to the first valve body portion 411, and the valve piece 42 is under the pressure of the gas. The gas is circulated to the surface for the patient to inhale the gas storm. However, when the gas discharged by the patient flows to the second valve body portion 412, the closing piece 42 Α - the reverse pressure action if j, the gas is not defeated The second plug 411 is discharged from the gas bypass passage 417 to the outside. Further, when the gas pressure in the back pressure chamber 32 is greater than the top thrust of the first elastic member 382 applied to the ball plunger 381, the ball plunger 381 is subjected to the back pressure chamber. The air pressure in the 32 is driven, and the displacement is generated in the direction of the flow restricting member 343, so that the excessively high gas pressure in the back pressure chamber 32 is released through the bubble pressure passage 34 and the spray L 344 until the gas pressure in the back pressure chamber 32 is When the first elastic member is the same as the top thrust applied to the ball plunger 381, the ball plunger 381 abuts against the shoulder portion 345 formed adjacent to the large and small aperture portions 341, 342 by the top thrust of the first elastic member 382. The ship passage 34 is closed so that the gas in the f-pressure chamber 32 cannot be discharged to the outside. Therefore, By the configuration of the (4) valve 38, the air pressure in the back pressure chamber 32 can be maintained at a constant value, so that the patient can safely receive treatment under the pressure of the mean 气压 9 1285121, because the gas exchange action of the patient inhaling and exhaling mainly occurs in In the one-way valve 4, and in the present embodiment, the one-way valve 4 is a disposable valve body, so that the next patient does not have to worry about hygiene when using it. Moreover, the gas discharged by the patient is used by the valve. The stop of the piece 42 does not flow to the control valve 3, so that the droplets and bacteria discharged from the patient's mouth do not remain in the control valve 3, making the control valve 3 easy to clean. It is worth mentioning that the check valve 4 can also be used. The valve body for repeated use is not limited to the embodiment. In the above, the respirator of the present invention allows the patient to inhale and exhale the gas by the configuration of the disposable check valve 4. The exchange action mainly occurs in the check valve 4, and the gas discharged by the patient is discharged from the single-package valve 4 to the outside without flowing to the control valve 3, causing pollution to the control valve 3, making the control valve 3 easy to clean, so the next Patients who use do not have to worry about health and safety The above-mentioned concerns are indeed achieved by the present invention. However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, to apply for a patent according to the present invention. The simple equivalent changes and modifications made by the scope of the invention and the description of the invention are still within the scope of the invention.
