本发明涉及一种自动喂食 /抽痰装置， 特别是指一种自动且可于喂食 /抽痰 过程中侦测患者是否不适的自动喂食 /抽痰装置。 背景技术
对许多类型的神经系统疾病来讲， 随着病情的进展， 咽喉部肌肉都会逐步 停止正常工作， 而导致吞啦困难、 窒息、 呛咳、 失声或呼吸困难的症状， 当患者 吞咽困难时， 通常会吃的更少， 并因此不能摄入足够的营养， 此时， 即需通过喂 食管 （鼻胃管一经鼻腔插入， 通过食道进入胃， 或胃管一通过手术， 直接经腹部 插入胃中）接受流质食物， 而在多数情况下， 喂食管可以帮助预防疾病并延长生 命 （在类似肌萎缩性侧索硬化症（ALS) 等疾病中， 喂食管可以作为常规治疗方 法的一部份， 因为在临近疾病晚期， 吞咽功能都可能受到影响） 。
另外， 喂食管除可针对吞咽困难的患者外， 亦可应用于施行口腔、 咽喉、 食道、 气管手术后病人、 意识不清、 严重忧郁或厌食者， 使用时， 医护人员将液 态食物（如牛奶或果汁…等）倒入灌食空针， 并将灌食空针提高约 30〜45公分， 让食物借着重力原理慢慢灌入， 然而由于每次喂食量约 250 cc〜350 cc、时间不 可少于 15〜20分钟， 且喂食过程中， 患者有时出现恶心、 呕吐、 腹泻、 发汗、 痉挛及心跳加速， 此时需立刻停止喂食动作， 由医护人员处理； 因此喂食过程医 护人员不但要进行灌食动作， 还必须随时留意患者是否有任何不适， 因此很容易 产生医疗意外。
另外， 这些患者若有做气切， 常常也有插气管， 插管来抽痰或喂食过程中 或呕吐过程中， 有时食物往气管流入导致吸入性肺炎， 故需有抽痰的动作。
由此可见， 上述习用方法仍有诸多缺失， 实非一良善之设计者， 而亟待加 以改良。 发明内容

本发明所提供的自动喂食装置的使用流程如下所述：
步骤一、 以控制器或手动方式将 H向控制阀连接灌食空针 5及液态食物补 充桶 1的方向通道打开；
步骤二、 以切换开关 2或三向阀 3打开液态食物补充桶 1的储水槽； 步骤三、 利用空气泵浦带动灌食空针 5内的活塞 6抽取储水槽中 20 cc〜 30cc的温水至灌食空针 5内； ,
步骤四、 关闭液态食物补充桶 1的储水槽；
步骤五、 以控制器或手动方式将三向控制阀连接液态食物补充桶 1的方向 通道关闭；

步骤十八、 重复步骤二〜步骤七， 将残留喂食管内的液态食物以温水冲入 患者胃中， 以避免残留食物附着于喂食管壁。
本发明所提供的自动喂食装置中， 该控制器可外接或内设一蜂鸣器或警示 装置， 而该灌食空针 5及喂食管内均可设一压力侦测器， 该灌食空针 5内的压力 侦测器用以侦测灌食空针 5 内液态食物或温水残余量 （当所侦测的压力忽然变 小，表示灌食空针 5内的液态食物或温水已灌食完毕，当所侦测的压力忽然变大， 则表示喂食管堵塞，导致灌食空针 5内的液态食物或温水无法经喂食管流入患者 胃中） ， 再者， 该喂食管内的压力侦测器则可侦测喂食过程中， 患者是否有呕吐 现象（当喂食管内压力侦测器所侦测的压力变大， 即表示患者发生呕吐， 导致胃 中食物反灌喂食管， 致使喂食管内压力增加） ， 而当上述灌食空针 5及喂食管内 压力侦测器侦测出压力变化时，则由控制器控制蜂鸣器或警示装置发出声响或灯 号， 以通知医护人员进行处理， 又， 该三向控制阀与液态食物储存桶间可设置一 红外线侦测器， 当空气泵浦抽取液态食物至灌食空针内时， 若液态食物储存桶内 已无液态食物或水， 则该红外线侦测器则传送讯号予控制器， 由控制器控制蜂鸣 器或警示装置发出声响或灯号， 以通知医护人员， 由医护人员停止喂食并补充液 态食物储存桶的内容物。
本发明所提供的自动喂食装置于喂食过程中， 以侦测带绑缚于患者躯干上 (亦可依测量的方法不同而放置于胸、 手臂或鼻子)， 通过患者吸气将侦测带向外 撑， 使侦测带内的二触碰开关相接触， 以侦测患者的呼吸频率， 而当侦测出患者 呼吸频率过快， 即代表患者于喂食过程中产生不适而导致呼吸加快， 此时控制器 则控制蜂鸣器或警示装置发出声响或灯号， 以通知医护人员进行处理， 另外， 该 侦测带上亦可以加速度，心电图侦测器或肌电图侦测器或压力侦测器代替呼吸侦 测器， 或于侦测带上设置麦克风以监听患 之呼吸及心跳声， 再者， 该侦测带上 亦可设置湿度侦测器， 以侦测患者的流汗程度， 而该控制器亦可连接一可贴于患 者耳后或手指以侦测缺氧程度的血氧浓侦测器若侦测带上有压力侦测器绑缚在 手臂上测脉搏即心跳速率。
本发明所提供的自动喂食装置中， 该喂食管上可装设一与控制器连接的温 度侦测器， 该温度侦测器可侦测通过喂食管的液态食物或水的温度， 藉由控制器 设定侦测温度上、 下限， 使温度侦测器侦测到液态食物或水的温度超过设定温度 上、下限时，可由控制器停止喂食动作，并以蜂鸣器或警示装置发出声响或灯号， 以通知医护人员进行处理。
本发明所提供的自动喂食装置中， 该侦测带亦可以挂于患者鼻上的鼻吸管 代替， 且该鼻吸管后面设置有一压力侦测器， 通过鼻吸管内因患者的呼气及吸气 而产生压力变化来计算患者的呼吸频率， 另外， 该鼻吸管亦可与一氧气供应装置 连接， 而于患者吸气时提供氧气。
本发明所提供的自动喂食装置中， 该液态食物补充桶 1中可装设容量量表 或测重器， 以侦测患者每次的灌食量； 该三向控制阀上则可设置一流速侦测器， 该流速侦测器可以可用细绳、 光反射、 流速计或正负压利用 PV=NRT的原理进 行流速侦测， 另外， 该控制器上可设置一定时器来观察喂食速度及时间， 且该控 制器可以有线或无线的方法与录像装置相连接， 利用该录像装置纪录喂食时间、 喂食量、 患者名称、 有无副作用反应、 护理人员名称及患者呼吸时之胸部起伏作 为测量患者的呼吸频率。
又， 本发明所提供的自动喂食装置中， 该喂食管末端亦可设置一奶瓶以供 婴幼儿或动物喂食之用， 且奶瓶前端一侧延伸有一管体， 该管体内设有一薄膜与 外界透气， 目的在平衡奶瓶内外压力差。
请参阅图 3及图 3A， 本发明所提供的自动喂食装置中， 该灌食空针 5的 前端及后端管壁可设置红外线侦测器 Ί与控制器连接，通过红外线侦测器 7以侦 测灌食空针 5内活塞 6的位置，当红外线侦测器 7侦测到活塞 6位置已达灌食空 针 5前端时， 即代表灌食空针 5内的温水或液态食物已全部灌入患者胃中，此时 该控制器则控制空气泵浦抽取液态食物至灌食空针 5内，而当活塞 6位置到达灌 食空针 5后端红外线侦测器 7的位置时（亦即达每次灌食的预定量时）， 则该控 制器控制空气泵浦停止抽取动作， 另外， 该本发明所提供的自动喂食装置亦可于 针筒盖接头上设置超音波侦测器 8， 以侦测活塞 6位置。 请参阅图 1及图 4， 本发明所提供的自动喂食装置中， 由于采用以空气泵 浦推动灌食空针 5内的活塞 6， 而将温水或液态食物灌入患者胃中， 因此为避免 活塞 6在推行中产生停顿动作而致使患者产生不适的现象，故本发明所提供的自 动喂食装置于灌食空针 5及空气泵浦间设有一控制阀组及一空气容槽 9， 其中， 该控制阀组为由三向阀 Vi、 三向阀 V2、 三向阀 V3、 三向阔 V4、 三向阀 V5、 三向阀 V6、 三向阀 V6、 泄压阀 (leaking valve) Μ~ι、 泄压阀 (leaking valve) Vg 及泄压阀 (leaking valve) Vg所组成， 各三向阀的两侧分别为方向通道 A2及方向 通道 A3， 而方向通道 A2及方向通道 A3 间则为方向通道 Αι， 其中该泄压阀 (leaking valve) Vj及泄压阀 (leaking valve) V9为进气用， 泄压阀 (leaking valve) Vs则为泄气用， 且该泄压阀 (leaking valve) Ve及泄压阀 (leaking valve) Vg互相 连动，该三向闽 V1之方向通道 A2与空气泵浦的出气口连接，三向阀 V1的方向 通道 A3与三向阀 V3的方向通道 A2连接， 三向阀 V1的方向通道 Αι与三向阀 V4的方向通道 A3连接， 三向阀 V2的方向通道 A2与空气泵浦的进气口连接， 三向阀 V2的方向通道 Αι与三向阀 V4的方向通道 A2连接， 三向阀 V2的方向 通道 A3与三向阀 V3的方向通道 A3连接， 三向阀 V3的方向通道 A1与三向阀 V6的方向通道 A3连接， 三向阀 V4的方向通道 Αι与三向阔 V5的方向通道 A3 连接， 三向阀 V6的方向通道 A1与空气容槽 9连接， 三向阀 V5的方向通道 A2 与泄压阀 (leaking valve) V7及泄压阀 (leaking valve) Vs连接，三向阀 V6的方向 通道 A1与泄压阀 (leaking valve) V9连接， 而三向阀 V6的方向通道 A2则与灌 食空针 5连接， 再者， 该空气容槽 9一端为与三向阀 V5的方向通道 连接， 另一端则为一末端具细微针孔 (pine hole) 92的引气针 91； 其使用流程为：
步骤一、 空气泵浦进气时， 将三向阀 V5的方向通道 A2、 三向阀 V4的方 向通道 A3、 三向阀 V2的方向通道 A3关闭；
步骤二、 空气泵浦抽取空气容槽 9内的空气；
步骤三、 空气泵浦出气时， 将三向阀 V1的方向通道 Αι、 三向阀 V3的方 向通道 A3、 三向阀 V6的方向通道 Αι关闭；
步骤四、 使空气泵浦所抽取空气容槽 9内的空气作为起始动力推动灌食空 针 5内活塞 6; .
步骤五、 重复步骤一；
步骤六、.空气泵浦由引气针 91的细微针孔 (pine hole) 92持续抽取空气； 步骤七、 重复步骤三； 步骤八、 使空气泵浦以由引气针 91的细微针孔 (pine hole) 92持续抽取的 空气作为持续推动灌食空针 5内活塞 6的动力。
上述流程中， 该空气泵浦以空气容槽 9内的空气作为推动灌食空针 5内活 塞 6的起始动力，主要是因为活塞 6与灌食空针 5壁面接触， 因此一开始必须以 较大力量推动活塞 6， 而当一开始推动活塞 6后， 后续使活塞 6持续前进所需的 推力即可减小， 因此以引气针 91的细微针孔 (pine hole) 92持续抽取的空气作为 动力即可， 故可避免空气泵浦在推动活塞 6时， 因推动活塞 6的起始动力及持续 动力相同，而使活塞 6推进时产生停顿现象；另夕卜，由于该泄压阀 (leaking valve) Vs及泄压阀 (faking valve) Vg互相连动， 当泄压阀 (leaking valve) 开启时， 泄压阀 (leaking valve) Vg即关闭， 反之亦然， 因此当泄压阀 (leaking valve) Vg 开启进气时， 则将灌食空针 5内的活塞 6向前推， 而泄压阀 (leaking valve) V8 开启泄气时， 则将灌食空针 5内的活塞 6向后拉， 以作为本发明自动喂食装置使 用前活塞 6与灌食空针 5壁面磨合之用， 再者， 泄压阀 (leaking valve) V7则于 喂食完毕后作为迅速补空气容槽 9内的空气以利下次进行喂食之用。

步骤三、以切换开关 2或三向阀 3打开氧气 /水供应装置 4的氧气供应装置； 步骤四、 使氧气供应装置由抽痰管供给患者一分钟左右的氧气；
步骤五、以切换开关 2或三向阀 3关闭氧气 /水供应装置 4的氧气供应装置； 步骤六、 以控制器或手动方式将三向控制阀将连接抽痰器及抽痰管的方向 通道打开;
步骤七、 启动抽痰器， 利用抽痰管的抽痰孔将痰吸入抽痰器中；
步骤八、 关闭抽痰器；
步骤九、以控制器或手动方式将三向控制阀将连接氧气 /水供应装置 4及抽 痰管的方向通道打开；
步骤十、以切换开关 2或三向阀 3打开氧气 /水供应装置 4的氧气供应装置， 以供应患者氧气；
步骤十一、以切换开关 2或三向阀 3关闭氧气 /水供应装置 4的氧气供应装 置；
步骤十二、 医护人员转动抽痰管， 使抽痰管的抽痰孔朝向其它角度； 步骤十三、 重复步骤六〜步骤十二至抽痰管旋转旋转 360° (即抽痰孔旋 转 360° ， 对每一角度均进行过抽痰动作） ；
步骤十四、 关闭抽痰器；
步骤十五、 将抽痰管由患者身上拔出。
当本发明所提供的自动抽痰装置对患者进行完抽痰动作后， 则可以切换开 关 2或三向阀 3打开氧气 /水供应装置 4的储水槽， 并将三向控制阀切换使氧气 / 水供应装置 4连接抽痰器或抽痰管，然后以空气泵浦抽取储液槽中的水清洗抽痰 器及抽痰管， 再者， 本发明于抽痰过程中， 是以侦测带绑缚于患者躯干上， 通过 患者吸气将侦测带向外撑， 使侦测带内的二触碰开关相接触， 以侦测患者的呼吸 频率， 而当侦测出患者的呼吸频率过快， 即代表患者于抽痰过程中产生不适而导 致心跳加快， 此时控制器则控制蜂鸣器或警示装置发出声响或灯号， 以通知医护 人员进行处理， 另外， 该侦测带上亦可以加速度， 心电图或肌电图侦测器或压力 侦测器代替呼吸侦测器可以加速度或肌电图侦测器，或于侦测带上设置麦克风以 监听患者的呼吸及心跳声。 又， 本发明所提供的自动抽痰装置中， 该氧气供应装 置出口可装设雾化器， 以供需要使用气雾吸入剂型的患者使用， 若侦测带上有压 力侦测器绑缚在手臂上测脉搏即心跳速率， 又， 该三向控制阀与氧气 /水供应装 置 4间可设置一红外线侦测器， 当供应氧气予患者时， 若该红外线侦测器侦测到 无氧气通过， 则该红外线侦测器则传送讯号予控制器， 由控制器控制蜂鸣器或警 示装置发出声响或灯号， 以通知医护人员， 由医护人员停止抽痰动作。
本发明所提供的自动抽痰装置中， 该侦测带上亦可设置湿度侦测器， 以侦 测患者的流汗程度，而该控制器亦可连接一可贴于患者耳后或手指以侦测缺氧程 度的血氧浓度侦测器， 再者， 该侦测带亦可以挂于患者鼻上所鼻吸管代替， 且该 鼻吸管后面设置有一压力侦测器，通过鼻吸管内因患者的呼气及吸气而产生压力 变化来计算患者的呼吸频率， 另外， 该鼻吸管上亦与一氧气供应装置连接， 而于 患者吸气时提供氧气。
