Technical field
The utility model relates to medical gas conveying equipment technical field, especially a kind of oxygen delivery pipeline.
Background technique
When hospital conveys the sterilizing filter replacement filter core on the pipeline of oxygen, it is often necessary to close the pipe of conveying oxygen
It makes troubles after stopping supply oxygen to patient and doctor on road；Some provides unfiltered oxygen using the method for bypass channel
It is used for patient, it is possible to bring adverse consequences to patient, generate doctor-patient dispute.
Utility model content
Technical problem to be solved by the utility model is: overcoming the deficiencies in the existing technology, provide a kind of without stopping supplying
Answer the oxygen delivery pipeline of oxygen, i.e. replaceable filter element.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of oxygen delivery pipeline, including general pipeline
Road is from left to right sequentially installed with oxygen concentration sensor, shut-off valve one, sterilizing filter, shut-off valve two and oxygen on main pipe rail
Flowmeter further includes bye-pass, and the main pipe rail between oxygen concentration sensor and shut-off valve one is connected by pipeline and bye-pass left end
Logical, the main pipe rail between shut-off valve two and oxygen flow meter is connected to by pipeline with bye-pass right end, and one is equipped on bye-pass
To external thread stop valve, two external thread stop valves are connected to by hose, and hose both ends are respectively equipped with annular male half coupling and can be rotated
Ground is sleeved on the hex nut on hose, hex nut be equipped with it is matching with annular male half coupling, for prevent hex nut from
The annular inner stopper to fall off on hose, between annular male half coupling and the external screw joint of external thread stop valve be equipped with sealing ring, six
Angle nut can be such that external thread stop valve is connected to hose after being spirally connected with the external screw joint of external thread stop valve.
The beneficial effects of the utility model are: the utility model can be replaced under the situation that do not stop the supple of gas or steam to sterilizing filter
Filter core, and provide through the filtered oxygen of sterilizing filter, to be brought conveniently to patient and doctor.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing.

Specific embodiment
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
A kind of oxygen delivery pipeline as illustrated in fig. 1 and 2, including main pipe rail 1 are from left to right successively installed on main pipe rail 1
There are oxygen concentration sensor 2, shut-off valve 1, sterilizing filter 4, shut-off valve 25 and oxygen flow meter 6, further includes bye-pass 7, oxygen
Main pipe rail 1 between concentration sensor 2 and shut-off valve 1 is connected to by pipeline with 7 left end of bye-pass, shut-off valve 25 and oxygen
Main pipe rail 1 between flowmeter 6 is connected to by pipeline with 7 right end of bye-pass, and a pair of of external thread stop valve is equipped on bye-pass 7
8, two external thread stop valves 8 are connected to by hose 9, and 9 both ends of hose are respectively equipped with annular male half coupling 10 and are rotatably mounted around
Hex nut 11 on hose 9, hex nut 11 be equipped with match with annular male half coupling 10, for prevent hex nut 11 from
The annular inner stopper 12 to fall off on hose 9 is equipped with close between annular male half coupling 10 and the external screw joint 13 of external thread stop valve 8
The external screw joint 13 of seal, hex nut 11 and external thread stop valve 8 can make external thread stop valve 8 and hose 9 after being spirally connected
Connection.
In use, pulling hex nut 11 with spanner, 9 one end of hose and an external thread stop valve 8 are disconnected, then
Spare 4 one end of sterilizing filter is connected by the Shu Jieyu external thread stop valve 8, spare sterilizing filter both ends difference
With external screw joint, one end that hose 9 disconnects is connect with the spare sterilizing filter other end then, is then turned on spare remove
The external thread stop valve 8 at bacterium filter both ends, bye-pass 7 is in parallel for gaseity with main pipe rail 1 at this time；It is then powered off cut-off
Valve 1 and shut-off valve 25, i.e., the filter core of the sterilizing filter 4 on replaceable main pipe rail 1, oxygen is continued by bye-pass 7 at this time
Filtered oxygen is provided, seamless switching is realized；Filter element replacing finishes, opening stop valve 1 and shut-off valve 25, then turns off
Two external thread stop valves 8, remove spare sterilizing filter, one end that hose 9 is disconnected again with original external thread stop valve 8
Connection, to guarantee that 9 inner hole of hose is not contaminated, at this point, oxygen is still provided by main pipe rail 1.
Above embodiment is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with this skill
The personage of art can understand the content of the utility model and be implemented, and the protection model of the utility model can not be limited with this
It encloses, all equivalent change or modifications according to made by the spirit of the present invention essence should all cover the protection model in the utility model
In enclosing.
