In addition, some patients have respiratory diseases and need to breathe through this kind of breathing. The gas is supplied to treat #, so the sucker and the conduit through which the gas is supplied are generally used for medical behavior. However, the (treatment) gas supplied to the patient in the early stage is not warmed, and the gas that does not match the temperature and the physiological condition may cause coughing or other discomfort. Therefore, there is a proposed improvement by the related art, and the respirator catheter 2 shown in FIG. 1 has a catheter body 2 and a heating wire 22 (made of a high-resistance material) is disposed in the catheter body 21 by means of - control The device 3 manipulates the warming action of the heating wire 22 to apply the gas in the conduit body 21. Although such a respirator 2 successfully solves the problem that the supply gas temperature is too low, the problem '(4) the heating wire 22 must be placed in the catheter body 21, and the heating wire is not connected or fixed to the inner circumferential surface 211 of the guide body 21, Only the supply of the material at the mouth of the pipe, the addition of _ 22 can not be caused by the twigs of the raw silk 22 explosion and affect the heating effect. [Explanation] Therefore, the object of the present invention is to provide a respirator having an effective function and structure.

Taking Figure 2 as an example, the respirator is located on the left side of the respirator catheter ' in the figure. The gas supply unit is located in the respirator guide 2 in the figure; ^, and the gas flow direction is as indicated by the arrow 3 . The respirator is a kind of surface I ′ which can cover the mouth and nose of the patient, and the 1 气体 gas supply I element is a gas supply cylinder, and a device for controlling gas in and out is added to the bottle mouth, and the supply gas is mostly oxygen. A preferred embodiment of the invention comprises a hollow tubular body, a rib 12 and a heating unit 13. The tubular body 11 has an inner surface m and an outer surface 112 defining a passage 113 for gas to flow unidirectionally from the gas supply unit to the respirator. The body n further has a use end 114 adjacent to the respirator and a gas source end 115 adjacent to the gas supply unit. 1289066 and the rib 12 is spirally wrapped around the outer surface 112 of the tubular body 11 along the length of the tubular body, and the helical ribs 12 are distributed at substantially equal intervals along the length of the tubular body U to provide along the tube. Uniform heating of the length of the body u. The heating unit 13 generates a heat source to heat the conveying gas in the passage 113 by using a flexible elongated electric heating element. In the embodiment, the heating unit 13 includes a plurality of electric resistance wires 131 (electric heating elements) disposed in the ribs 12, A first temperature sensor 132, a second temperature sensor 133, and a control device 134. The first temperature sensor 132 is electrically connected to the resistance wire j 3 ^ adjacent to the use end 114, and the second temperature sensor 133 is electrically connected to the resistance wire 131 adjacent to the gas source end 115. The control device 134, the second temperature sensor 133, the resistance wire 131 and the first temperature sensor 132 form an electrical circuit, which is familiar to those skilled in the art and will not be described again. Wherein, the pipe body 11 and the rib 12 are both made of a thermoplastic polyester elastomer, and the present embodiment is made of DuPont's hytrel (this is a trademark product registered by DuPont). Oxygen resin (9)... (10) Magic is also a viable alternative. The electric resistance wire 131 is embedded in the elongated rib 12 and then fixed to the outer surface 112 of the preformed tubular body U, so that the rib 12 of the embedded electric resistance wire 13 1 is formed in an integral state with the tubular body 11. As shown in FIG. 3, when the gas supply unit is turned on, the gas advances along the channel 113 (flowing from the right side to the left side in the figure), and at this time, the temperature rise of the resistor and the wire 131 can be started by the control device 134. At the same time of heating, the 1280906 first temperature sensor 132 can detect the gas temperature of the use end 114, and the second fox sensor 133 can detect the gas temperature of the gas source end 115, and all temperature sensing benefits 132, 133 detection The results are all sent back to the control device 134 and compared with the preset temperature for immediate monitoring. The temperature of the resistance wire 131 is transmitted through the material of the tube body 11, so that the flowing gas in the channel 113 is heated, so that the gas that is sent to the user's mouth and nose through the call will be an optimum temperature closer to the physiological state, thereby reducing the user's The discomfort of low temperature air.
在加熱進行同時，二溫度感應器132、133皆持續地檢 驗自其旁側通過的供應氣體溫度，若其中任一者132或133 感應結果顯示氣體溫度過高，則可及時通報控制裝置134, 由控繼m調整供應給電阻絲131之電流量，進而改 變氣體溫度。反之，若供應氣體溫度過高，也能夠利用同 樣的迴路系統回報控制裝置134，使得經由呼吸器導管i的 ，體溫度能夠更精微地被調整，確保進人使用者口鼻部的 氣體皆能達到最適或恆溫狀態。 此外，正因為電阻絲131被包 飞？Ί1达 溉匕埋於肋條12内，又肋條 吕體11為一體成形，整個呼 说1 及态導官1可適用於各種 常折狀悲，也就是說，該呼吸 ^吁及益導官1能夠適切地配合工 作裱楗的需求，進行多種角度 ，雷_ m η 丹又扪“斤’在肋條12保護之τ 電阻4⑶不易發生斷裂或者是鬆脫掉落， 功能得正常進行之外亦能增加其使用壽命。另:方面加太、 發明之電阻絲]31受到肋條 ，本 降低，在使用上較安全。所包覆，故外部之發熱程度 歸納上述，本發明之呼吸 π吕|透過將電阻絲】3】 8 l289〇66 :包埋於肋條12中，徹底阻絕電阻絲131散亂或混雜排列的 困擾，又肋條12螺旋纏繞於管體u之外表面112，對通道 中的流通氣體進行加熱，配合溫度感應器132、133與 控制裝置Π4,確保加熱作業以幾近恆溫的狀態進行，更能 在溫度過高或過低時靈活調整，因而確實能達到本發明之 目的。 惟以上所述者，僅為本發明之較佳實施例而已，當不 鲁 t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-種習知呼吸器導管之—使用狀態示意圖； 圖2是一局部侧視示意圖，說明本發明呼吸器導管之 一較佳實施例；及 圖3疋局部剖視圖，說明在該較佳實施例中，一電 φ P且絲被埋汉於1力條中並沿著導管本體呈螺旋狀圍繞的情 9 1289066 【主要元件符號說明】 1 呼吸器導管 12· · · 肋條 11 · · •管體 13· · · 加熱單元 111 · _ 内表面 131 · · 電阻絲 112 · • 外表面 132 · · 第一溫度感應器 113 通道 133 · · 第二溫度感應器 114 使用端 134 · · 控制裝置 115 氣體來源端 10While the heating is being performed, the two temperature sensors 132, 133 continuously check the temperature of the supply gas passing through the side thereof.
