Silence oxygen flowmeter

一种静音的氧气流量表

Abstract

A silence oxygen flowmeter comprises a body, an air inlet connector, an air outlet connector, a flow displaying pipe, an adjusting button, a humidification bottle and an overflowing pipe. The silence oxygen flowmeter is characterized by further comprising a shielding cover upper shell body and a shielding cover lower shell body. The small-opening end of the shielding cover upper shell body is connected with the body, the large-opening end of the shielding cover upper shell body is connected with the shielding cover lower shell body, and a formed sealing space wraps the humidification bottle. After the shielding cover upper shell body is connected with the shielding cover lower shell body, a formed sealing structure effectively and further insulates and reduces the noise led out from the humidification bottle, the silence of the oxygen flowmeter is achieved, and the problem that oxygen inhalation people and other patients in the same ward cannot fall asleep easily caused by the noise produced by an oxygen flowmeter in the prior art is solved. Meanwhile, the silence oxygen flowmeter has the advantages of being simple in structure, easy to manufacture, small in occupied space and low in cost.
一种静音的氧气流量表,包括本体、进气接头、出气接头、流量显示管、调节钮、湿化瓶和逸出管,其特征在于,还包括隔离罩上壳体和隔离罩下壳体,所述的隔离罩上壳体的小开口端与本体连接,所述的隔离罩上壳体的大开口端与所述的隔离罩下壳体连接,形成的密闭空间包覆着湿化瓶;隔离罩上壳体和隔离罩下壳体连接后,形成的密封结构有效地将从湿化瓶传导出的噪音进一步隔离和衰减,实现了氧气流量表的静音,解决了现有技术的氧气流量表因产生噪音,而影响吸氧者和同病房的其他患者难以入睡的问题;同时,本发明具有结构简单,易于制造,占用空间小,成本低的特点。
