Abstract
一种医用咬口器（100），其为一体成型而供使用者咬合并置入使用者的口腔（O），咬口器（100）包括一贯通孔道（1）、一上咬固槽（2）、一下咬固槽（3），贯通孔道（1）贯设咬口器（100），贯通孔道（1）一端具有一入口开口（11），另一端具有一口腔开口（12），口腔开口（12）用于连通使用者口腔（O）；上咬固槽（2）凹设于咬口器（100）的上表面；下咬固槽（3）凹设于咬口器（100）的下表面；下咬固槽（3）供下排牙齿（T2）咬合，上咬固槽（2）供上排牙齿（T1）咬合，下咬固槽（3）相距口腔开口（12）的距离大于上咬固槽（2）至口腔开口（12）的距离，因而使用者的下颚能往前提伸且使得使用者上颚与下颚形成错位。
Description
本发明涉及一种医用咬口器，特别是用于使用者口部伸入的内视镜检查、全身静脉镇静内视镜检查(即无痛内视镜)或胃镜检查时，协助使用者接受检查时维持其上下颚错位的张口嘴形，以利医疗人员顺利将内视镜伸入使用者口中进行检查的医用咬口器。
于执行全身静脉镇静内视镜检查(即无痛内视镜)时，患者受麻醉影响而处于无知觉状态，此时患者需侧躺并配戴咬口器，协助患者维持张口嘴形，以利医疗人员顺利将内视镜插入患者口中进行检查，然而患者往往因麻醉产生舌头后倒而阻塞上呼吸道而有缺氧之情形。
不仅如此，若施予患者的麻醉药物属于呼吸抑制剂时，还可能导致患者包括肺换气不足、血氧不饱和呼吸暂停等与呼吸相关的风险。因此，目前临床为避免患者因前述因全身麻醉而进行内视镜检查所产生各种风险问题，则是让患者采侧躺姿势避免呼吸道阻塞，但医师仍须透过生理参数的监控(心跳、血压等)，得知患者受测时舌头后倒压迫上呼吸道的情形，以避免产生缺氧等问题，但仍难以避免患者受检时产生缺氧、中风甚至死亡等风险。
然而现有的咬口器仅能提供患者在受检时维持张口嘴形、提供输氧/排二氧化碳通道，并无法避免舌头后倒而压迫上呼吸道与咬口器于患者口部稳定性不佳的问题，且输氧/排除二氧化碳的效果因通口距离鼻腔及上呼吸
道均有一段距离，患者无法透过这些通口得到充足的氧气，目前使用于临床的内视镜咬口器皆无法有效降低患者受检时可能存在的风险。
有鉴于此，如何发展一种可避免患者因麻醉产生呼吸抑制、舌头后倒而产生呼吸道阻塞等生理现象造成缺氧的危险，进而解决现有技术与现有产品的缺失，实为相关技术领域目前所需要解决的问题。

图1至图4示出了本发明的较佳实施例，本发明的一种医用咬口器100为一体成型而供一使用者咬合并置入、伸入于使用者的口腔O，其中医用咬口器100包括一贯通孔道1、一上咬固槽2、及一下咬固槽3，贯通孔道1贯设于
医用咬口器100，贯通孔道1于其中一端具有一入口开口11，另一端具有一口腔开口12，而口腔开口12用以连通使用者口腔O，入口开口11用以穿入内视镜设备装置(图中未示出)；上咬固槽2凹设于医用咬口器100的上表面，上咬固槽2对应并供上排牙齿T1咬合卡扣，下咬固槽3凹设于医用咬口器100的下表面，下咬固槽3对应并供下排牙齿T2咬合卡扣，下咬固槽3相距口腔开口12的距离大于上咬固槽2至口腔开口12的距离，亦即下咬固槽3相较于上咬固槽2远离于使用者的口腔O且下咬固槽3与上咬固槽2分别对应于下排牙齿T2与上排牙齿T1而错位设置。
此外，上咬固槽2垂直于贯通孔道1轴向13还包括一第一纵向平面P1，下咬固槽3垂直于贯通孔道1轴向13还包括一第二纵向平面P2，其中第一纵向平面P1与第二纵向平面P2相对应而非重叠，且第二纵向平面P2至口腔开口12的距离大于第一纵向平面P1至口腔开口12的距离。第一纵向平面P1与第二纵向平面P2沿轴向13相距1～12公厘(毫米)，亦即上咬固槽2与下咬固槽3沿轴向13大致相距1～12公厘。
换句话说，在上述较佳实施例中，本发明医用咬口器100能提供使用者上排牙齿T1咬合卡扣于上咬固槽2，下排牙齿T2咬合卡扣于下咬固槽3，使用者不需特别费力即可形成以下颚往前提伸的嘴形而咬合本发明的医用咬口器100。进一步言，本发明医用咬口器100能提供使用者于麻醉后，特别是深度麻醉后，在正躺姿势下仍可将下颚前提，避免舌头后倒造成上呼吸道压迫的问题，降低患者产生缺氧等风险。
此外，本发明与入口开口11、口腔开口12大致垂直方向的外表面还设有一供氧通道6及一排气通道7，使用者于麻醉后能藉由供氧系统例如氧气
瓶或液态氧瓶作为稳定供氧的氧源并经供氧通道6而得到外部供氧，并可利用排气通道7而将鼻部、口腔中的二氧化碳等自本发明医用咬口器100中排出(如图3、图4、图5、图6所示)。
在本发明其他实施例中，于贯通孔道1的内壁更环设一口腔供氧排气部4(如图4、图5、图6所示)，口腔供氧排气部4设有一近端供氧引道41及一远端排气引道42，近端供氧引道41及远端排气引道42相互错位且邻接环设于口腔供氧排气部4。不仅如此，近端供氧引道41相距口腔开口12的距离小于远端排气引道42至口腔开口12的距离，且远端排气引道42相较于近端供氧引道41远离于使用者的口腔而错位设置，近端供氧引道41与远端排气引道42间还设有一中隔板43。如此，近端供氧引道41较之现有技术、产品更能自供氧通道6所提供的氧气而从口腔O以更近的距离提供予使用者的上呼吸道，使用者于麻醉时更易接收氧气，且藉由中隔板43的分隔，近端供氧引道41所提供的氧气与远端排气引道42所排出的二氧化碳不会相混合，使得氧气与二氧化碳可分别自近端供氧引道41与远端排气引道42顺利地引进与排出。
另外，本发明还包括一鼻端供氧换气部5(如图4所示)，鼻端供氧换气部5呈一翼片状而与鼻端下缘端至上唇区域相对应。进一步言，鼻端供氧换气部5还设有一供氧换气道51(如图5、图6所示)。亦即本发明藉鼻端供氧换气部5而更有效地提供使用者以更近鼻端的距离供予氧气与排出二氧化碳。
当然，本发明不限于此，中隔板43自口腔供氧排气部4延伸而穿设至鼻端供氧换气部5。因此，供氧通道6连通于近端供氧引道41及鼻端供氧换气部5，亦即供氧换气道51与供氧通道6及近端供氧引道41相连通；另一方面，
排气通道7连通于远端排气引道42及鼻端供氧换气部5，亦即，供氧换气道51与排气通道7及远端排气引道42相连通。换句话说，本发明藉由近端供氧引道41及鼻端供氧换气部5以更近的距离供氧予使用者的口腔与鼻端。另藉由中隔板43的设置，自供氧通道6的氧气直接流通于近端供氧引道41及鼻端供氧换气部5，自远端排气引道42及鼻端供氧换气部5收集二氧化碳等气体则可经由排气通道7而排出。
综上所述，本发明能提供使用者以上排牙齿T1、下排牙齿T2咬合卡扣于上咬固槽2与下咬固槽3，使用者于正躺姿势下藉由本发明可将下颚前提，特别是使用者于麻醉后，亦可因下颚前提而避免舌头后倒造成上呼吸道压迫进而产生缺氧等问题。不仅如此，本发明亦可藉由供氧通道6、近端供氧引道41及鼻端供氧换气部5相互连通而以较近的距离及更有效率的方式提供予使用者氧气。
上述实施例仅用于说明本发明原理及其功效，并非用来限制本发明。因此本领域技术人员对上述实施例进行修改及变化仍不脱本发明之精神。本发明的保护范围由其权利要求限定。
