On the cavity of housing is divided into the filtering area on top and the buffering area of lower part, be filled with adsorbent in filtering area, partition plate is equipped with
The communicating pipe of filtering area and buffering area is connected, the perisporium of filtering area is equipped with exhaust pipe, and exhaust pipe is equipped with air bleeding valve, housing
Bottom wall center is fixed with the air outlet pipe for being connected with respirator, and air outlet pipe is connected with buffering area, and the end of exhaust pipe is connected to
In air outlet pipe, air outlet valve is installed between exhaust pipe and housing in air outlet pipe.
Middle part is equipped with cylindric deflector on the partition plate, and filtering area is divided into inner ring filtering area and outer shroud by deflector
Filtering area, is equipped with the flow-guiding mouth for connecting inner ring filtering area and outer shroud filtering area, institute between the upper end of deflector and the roof of housing
State and connected with inner ring filtering area communicating pipe, exhaust pipe is installed on filtering area perisporium bottom and is connected with outer shroud filtering area.
The roof of the housing is equipped with the ring protection set for covering on air inlet pipe periphery.
The communicating pipe is equipped with two, and two communicating pipes was symmetrically mounted on partition plate.
The exhaust pipe is equipped with two, and two exhaust pipes are symmetrically mounted on the perisporium of filtering area.
The utility model is sleeved on the filtering that the cavity of housing is divided into top on air inlet pipe periphery wall using bulkhead seal
Area and the buffering area of lower part, in surgical procedure, anesthetic gases enters buffering area by air inlet pipe, is then conveyed to by air outlet pipe
Patient, after operation, opens exhaust valve closure air outlet valve, anesthetic gases is inhaled from buffering area by communicating pipe into filtering area
Attached dose of absorbing and filtering, it can quickly absorb the anesthetic gases in anesthesia respirator pipeline, then enter by exhaust pipe again
Tracheae is conveyed to patient so that patient can rapid fluid resuscitation, and the utility model repeats utilization, economizes on resources.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of anesthetic gas filter, including housing 1, housing 1 are cylindric sealing cavity body, housing
