Description

Water seal filter core three-way pipe
Technical field
A kind of pipe jointer part in medical device research field is the utility model is related to, it is particularly a kind of to be suitable for bearing Press the water seal filter core three-way pipe of drainage system.
Background technology
In existing drainage system, generally by three-way pipe by negative pressure drainage bag, aspirator and for fixing The drainage bottle connection of negative pressure drainage bag, but three-way pipe simply connects three, inside does not set structure of only overflowing, works as negative pressure When liquid in drainage bag is fully loaded with spilling, it can be flowed into from three-way pipe in aspirator, cause aspirator to damage, there is also filtering The biochemical microorganism of pollution and medical smog pollution material leakage, pollute the vacuum source in hospital, influence the peace of medical worker and patient Entirely.Accordingly, it is now desired to a kind of band stops the three-way pipe for function of overflowing.Negative pressure equipment centered on aspirator.
Utility model content
The purpose of this utility model, is to provide a kind of water seal filter core three-way pipe.
The solution that the utility model solves its technical problem is:Water seal filter core three-way pipe, including threeway tube body, institute State be provided with threeway tube body the first siphunculus being connected with negative pressure drainage bag, the second siphunculus being connected with aspirator and with drainage The three-way pipe of bottle connection, is disposed with first through hole in first siphunculus, it is recessed that the first through hole is disposed with cricoid first Groove, the internal diameter of first groove are more than the internal diameter of first through hole, water seal filter core are disposed with the first groove.
Further as above-mentioned technical proposal is improved, the outer surface of the water seal filter core and the inner surface of the first groove Between formed annular venthole.
Further as above-mentioned technical proposal is improved, and three that gas can be allowed to pass through are disposed with inside the water seal filter core Tie up intercommunicating porosity.
Further as above-mentioned technical proposal is improved, and the axis of first siphunculus and the axis of the second siphunculus overlap, The axis of first siphunculus and the axis of three-way pipe are vertical, and the second siphunculus and three-way pipe are by integral molding techniques into three-way pipe Support body, the first adapter is reserved on the three-way pipe support body, and one end that the first groove is disposed with first siphunculus passes through sealing It is connected in the first adapter.
The beneficial effects of the utility model are:The utility model in the first siphunculus by being disposed with water seal filter core, just Often during work, the gas in negative pressure drainage bag after water seal filter core by flowing into aspirator, when the water of negative pressure drainage bag overflows After into the first siphunculus, the first groove is closed and closes its internal through hole by water seal filter core immediately after expanding rapidly, Water cannot continue through, and play function of only overflowing, prevent water from flowing in aspirator.The utility model is suitable for drainage system In.
Brief description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described.Obviously, described attached drawing is the part of the embodiment of the utility model, rather than entirely Portion's embodiment, those skilled in the art without creative efforts, can also obtain it according to these attached drawings His designing scheme and attached drawing.
Fig. 1 is the structure diagram of the utility model.
Embodiment
Carried out below with reference to the technique effect of the design of embodiment and attached drawing to the utility model, concrete structure and generation Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment It is the part of the embodiment of the utility model, rather than whole embodiments, the embodiment based on the utility model, the skill of this area The other embodiment that art personnel are obtained without creative efforts, belongs to the model of the utility model protection Enclose.In addition, all connection/connection relations being previously mentioned in text, not singly refer to component and directly connect, and refer to can be according to specific reality Situation is applied, by adding or reducing couple auxiliary, to form more preferably draw bail.
With reference to Fig. 1, water seal filter core three-way pipe, including threeway tube body is provided with the threeway tube body and negative pressure drainage The first siphunculus 1, the second siphunculus 2 being connected with aspirator and the three-way pipe 3 being connected with drainage bottle of bag connection, described first After siphunculus 1, the second siphunculus 2 and three-way pipe 3 are intersected at one inside first siphunculus 1, the second siphunculus 2 and three-way pipe 3 Connection, is disposed with first through hole 8 in first siphunculus 1, and the first through hole 8 is disposed with cricoid first groove 5, and described the The internal diameter of one groove 5 is more than the internal diameter of first through hole 8, and water seal filter core 4 is disposed with the first groove 5.Water seal filter core 4 uses Special substance, in the dry state, gas can be uniformly through in the case where there is water state, water seal filter core 4 is closed immediately, water-soluble Liquid cannot continue through.Water seal filter core 4 is nonpoisonous and tasteless pure ultra-high molecular weight polyethylene.
By being disposed with water seal filter core 4 in the first siphunculus 1, during normal work, the gas in negative pressure drainage bag passes through Flowed into after water seal filter core 4 in aspirator, after the water of negative pressure drainage bag is spilt into the first siphunculus 1, water seal filter core 4 is rapid The first groove 5 to be closed immediately after expansion and closes its internal through hole, water cannot continue through, and play function of only overflowing, Prevent water from flowing in aspirator.The utility model is suitable for drainage system.
