Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail:

As shown in Figure 1, a buoy-type two-way anti-bacterial low-noise oxygen absorber provided by the utility model includes a humidification bottle body 11 and a connected humidification bottle cap 7, and an air inlet pipe 16 is provided on the humidification bottle cap 7 And the outlet pipe 15, the air inlet pipe 16 is provided with the antibacterial filter 8, one end of the air inlet pipe 16 is connected with the flowmeter 1, the other end is connected with the conduit 10 in the bottle, and the other end of the conduit 10 is connected with a humidifier 12, The air outlet pipe 15 is provided with the antibacterial filter 4 and is connected with the nasal oxygen tube 6 .

As shown in Figure 1 and Figure 2, the utility model is characterized in that: the intake pipe 16 is connected to the flow meter 1 through the intake connection device, the intake connection device is composed of the connection nut 3 and the pipe joint 2, the connection nut 3 The internal thread is connected with the external thread provided on the top of the intake pipe 16, and the end of the connecting nut 3 is provided with a hole. Connect with flowmeter 1 by thread. The fast thread cap connection method between the flowmeter and the humidifier bottle cap makes it possible to quickly assemble and disassemble all the following parts starting from the humidifier bottle cap or tightening the screw cap, which is convenient for sterilization by conventional disinfection methods. The flowmeter and humidifier The separate setting of the humidifier eliminates the disadvantages of the upper cover of the humidification bottle and the inlet and outlet holes under the traditional flowmeter being humid all the year round, which breeds a large number of bacteria and cannot be sterilized, causing cross infection between patients, and effectively prevents the long-term corrosion of the flowmeter by water vapor , and avoid damage to the flowmeter caused by the wetting fluid entering the flowmeter due to excessive pressure.
