心脑内科用吸氧面罩
本专利技术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。
技术介绍
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。
技术实现思路
本专利技术针对不足,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。本专利技术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 ...
