The existing gas flow detection device uses the inflatable joint, the edge of the end of the inflatable joint has a seal ring, the pressure of the inflatable joint is detected, the silicon rubber ring and the outer edge of the end of the filter end are fitted, and then the gas is inflated to carry out the flow detection. The main problem of this method is that the mechanical contact pressure is produced when the inflatable joint is under pressure, and the mechanical extrusion pressure is produced from the end to the middle of the filter, so that the unsealed filter is temporarily sealed, and the gas is still leak in the area without sealing after the completion of the extrusion pressure, which causes the inaccurate detection. A big problem of quality. The utility model provides an intercalated gas flow detection device, which includes a fixed seat, an active inner cavity body, an outer cavity and an inflatable rod. The front end of the inflatable rod is provided with a sliding mechanism that can move up and down, and a seal ring is arranged between the front of the sliding mechanism and the front end of the inflatable rod, and the front end of the inflatable rod is inserted into the interior of the filter interface when the test is detected. After the inner cavity is inflated, it pushes down the sliding mechanism and oppresses the seal ring, and the seal ring expands outwards because of the pressure, so that the outer wall of the end of the inflatable rod is closely fitted to the inner wall of the detected filter, so as to achieve a reliable sealing effect.

一种内插式气流量检测装置
本技术属于医疗器械的制造设备
,涉及到一种过滤器的生产检测装置,特别是一种用于吸氧装置上的氧气过滤器的气流量检测装置。
技术介绍
吸氧装置是医疗行业临床上氧疗法应用非常广泛的装置,通常由一次性使用吸氧管及湿化装置两部分组成。一次性吸氧管是为患者提供氧气的通道,主要由软管、气源接头、氧气过滤器等组成,其中氧气过滤器由上盖、下盖、过滤膜组装而成,为了保证过滤膜不会出现破损,上盖、下盖组合后密封性良好,在组装过程中需要进行气流量检测,确保氧气过滤器能起到良好的过滤效果。现有气流量检测装置是利用充气接头,充气接头端部边缘设有密封圈,检测时充气接头下压,利用硅胶圈和过滤器端部外边缘贴合,然后进行充气,在充气管路后端设有精密流量开关,进行流量检测。这种方法存在的主要问题是充气接头下压时产生了机械接触压力,对过滤器从端部到中间产生了机械挤压力,使原本没有密封的过滤器暂时密封,在检测完成挤压力消失后没有密封的部位依然漏气,从而造成检测不准确,存在较大的质量隐患。
技术实现思路
本技术是针对现有的气流量检测装置存在的上述缺点,提供一种能够从过滤器产品内壁密封并进行充气,实现可靠的气流量检测的目的。本技术提供了一种用于医用过滤器内侧气流量检测装置。它解决了现有从过滤器外侧端部检测容易压迫产品造成检测不准确或伤害产品内部结构及组成等技术问题。本技术通过下列技术方案来实现:一种内插式气流量检测装置,包括固定座、活动内腔体、外腔体和充气杆。固定座表面上端设有安装孔,用于固定整个气流量检测装置,在固定座上方设有通过充气能够使活动内腔向下运动的进气孔,在固定 ...
