Description

一种心脑内科用吸氧面罩
技术领域
本发明涉及一种吸氧用的医疗器械，尤其涉及一种心脑内科用吸氧面罩。
背景技术
在临床医学中，尤其是在心脑内科，经常会使用到吸氧工具，较常用的有吸氧面罩和吸氧鼻塞，吸氧面罩和吸氧鼻塞都能够提高蓄积气体的利用率，进而提高吸入氧气的浓度，适用于呼吸困难的患者。吸氧面罩在使用时罩于患者的鼻子和口上面，能够有效快速的提高血氧饱和度，改善病人缺氧状态，多适用于重症、昏迷和术后的患者，待患者病情好转、需要长期低流量吸氧时，就不能再继续使用吸氧面罩，因为此时患者会感到憋闷，所以要及时更换吸氧鼻塞，这无疑造成了医疗器械的浪费。而且，有的病人病情时好时坏，需要多次更换吸氧工具，也带来了更多的工作量。
发明内容
本发明针对不足，提供一种能够自由切换、使用方便、避免浪费的心脑内科用吸氧
面罩。
本发明解决上述技术问题的技术方案如下：一种心脑内科用吸氧面罩，包括鼻口罩体，鼻口罩体密闭连通有进气管，其特征在于，鼻口罩体上密闭连接有套筒，套筒两端均带开口，套筒将鼻口罩体内侧和外侧的空间连通，位于鼻口罩体内侧的套筒侧壁上开设有导气口，导气口与进气管之间通过软管密闭连通；套筒内前后滑动密闭连接有鼻塞，鼻塞为里端开口、外端封闭的圆筒状，鼻塞的外端固定连接有推杆，鼻塞的侧壁上开设有连通口，连通口的运动轨迹经过导气口；导气口后侧套筒的侧壁上还开设有换气口，连通口与导气口相交后、换气口将鼻口罩体内侧和外侧的空间连通。
根据所述的心脑内科用吸氧面罩，其特征在于，所述套筒与鼻口罩体为软连接。
根据所述的心脑内科用吸氧面罩，其特征在于，所述套筒位于所述鼻口罩体中部。
根据所述的心脑内科用吸氧面罩，其特征在于，所述连通口位于所述鼻塞侧壁的后端，所述导气口位于所述套筒侧壁的前端。
根据所述的心脑内科用吸氧面罩，其特征在于，所述连通口和导气口均为圆形口，连通口的直径小于导气口的直径，连通口的面积是导气口面积的1/3至4/5。
根据所述的心脑内科用吸氧面罩，其特征在于，所述连通口为圆形口，所述导气口为沿连通口运动方向设置的条形口，导气口的长度是连通口直径的1.5至3倍。
根据所述的心脑内科用吸氧面罩，其特征在于，所述推杆外端固定连接有握柄。
根据所述的心脑内科用吸氧面罩，其特征在于，所述推杆上固定连接有挡杆，挡杆与推杆互相垂直，挡杆的长度大于推杆与所述套筒内壁之间的距离。
本发明将鼻塞融合在了面罩中，当遇到重症、昏迷的患者需要急救时，向后抽拉鼻塞，本发明便可作为吸氧面罩使用，当病人病情好转后，向前推动鼻塞，将鼻塞插入患者鼻中，患者便能进行长时间的低流量吸氧，两种吸氧方式可以自由切换，操作使用方便。且本发明一物多用，避免了浪费。

具体实施方式
以下结合附图对本发明的原理和特征进行描述，所举实例只用于解释本发明，并非用于限定本发明的范围。
如图1至图4所示，一种心脑内科用吸氧面罩，包括鼻口罩体1，鼻口罩体1密闭连通有进气管10，鼻口罩体1上密闭连接有套筒4，套筒4位于鼻口罩体1中部。套筒4两端均带开口，套筒4将鼻口罩体1内侧和外侧的空间连通，套筒4与鼻口罩体1为软连接，便于调节套筒4的角度，以利于向病人鼻中插入鼻塞2。
位于鼻口罩体1内侧的套筒4侧壁上开设有导气口8，导气口8与进气管10之间通过软管9密闭连通；套筒4内前后滑动密闭连接有鼻塞2，鼻塞2为里端开口、外端封闭的圆筒状，鼻塞2的外端固定连接有推杆5，鼻塞2的侧壁上开设有连通口3，连通口3的运动轨迹经过导气口8。当需要本发明作为面罩使用时，向后抽拉鼻塞2，套筒4后端被封堵，套筒4前端与进气管10连通，病人可以正常吸氧；需要本发明仅作为鼻塞使用时，向前推动鼻塞2，使连通口3与导气口8交叉重叠，氧气经鼻塞2出来，将鼻塞2插入病人鼻中便可使用。同时，通过控制连通口3与导气口8重叠面的大小，还能一定程度上控制氧气的流速。
导气口8后侧套筒4的侧壁上还开设有换气口11，连通口3与导气口8相交后、换气口11将鼻口罩体1内侧和外侧的空间连通。在病人使用鼻塞后，由于换气口将鼻口罩体1内侧和外侧的空间连通，因此病人并无不适之感。
所述连通口3位于鼻塞2侧壁的后端，导气口8位于套筒4侧壁的前端，这样能够缩短鼻塞2的整体长度，使本发明结构紧凑。
作为一种实施例，所述连通口3和导气口8均为圆形口，连通口3的直径小于导气口8的直径，连通口3的面积是导气口8面积的1/3至4/5。
作为另一种实施例，所述连通口3为圆形口，所述导气口8为沿连通口3运动方向设置的条形口，导气口8的长度是连通口3直径的1.5至3倍。
另外，推杆5外端固定连接有握柄7。推杆5上固定连接有挡杆6，挡杆6与推杆5互相垂直，挡杆6的长度大于推杆5与所述套筒4内壁之间的距离。通过挡杆6能够控制鼻塞2的伸入长度，也能避免连通口3过于向内，与导气口8错开，影响病人吸氧。
