Description
Technical field
The utility model relates to a kind of health care apparatus, specifically a kind of one-way valve formula three-way connector.
Background technique
It is required to use three-way connector device, threeway when carrying out single operation either more manpower arts at this stage
Connector usually requires connection bag of saline, injection needle and needle cylinder device, and existing three-way connector is mostly by comparing complicated
Mechanical structure realize that structure is complex, during being operated, use is more troublesome, or even need more people same
When operation could complete the switching in channel, wasting manpower and material resources, and reduce working efficiency, therefore, a kind of knot of urgent clinical needs
Structure is simple and convenient, does not need the device for wanting complex operations to can be achieved with threeway connection.
Utility model content
The purpose of this utility model is in view of the deficienciess of the prior art, providing a kind of one-way valve formula threeway connection
Device, its technical solution is as follows:
A kind of one-way valve formula three-way connector, including the first connector, the second connector and third connector；Described three connect
Head is respectively connected with two pipelines, and the pipeline of three connectors is respectively connected with to the connecting pipe of the generally triangle of composition one；And
First connector is circumscribed with bag of saline, and second connector is then circumscribed with injection needle, and the third connector is then outer
It is connected to syringe；And one-way valve, and the first connector and second are also separately installed in pipeline interconnected between three connectors
The communication direction of one-way valve between connector is that the first connector is directed toward the second connector；List between first connector and third connector
It is that the first connector is directed toward third connector to the communication direction of valve；And the company of the one-way valve between the second connector and third connector
Logical direction is that third connector is directed toward the second connector.
Preferably, the one-way valve is respectively mounted the middle position of the pipeline of connection between the knuckles, and described
One-way valve be set as four valve structures valve piece constitute.
Preferably, first connector, the second connector and third connector and pipeline can be detachable by bolt arrangement
Installation.
The utility model has the advantages that the utility model has the following beneficial effects: being separately connected pipeline by three connectors in the present apparatus
The connector of the integral triangle of structure, and the equipment accordingly connected outside setting connector, and connected according to each connector
Equipment connection between the knuckles pipeline in one-way valve, while the circulating direction of corresponding setting one-way valve are set, can
Very easily realization is injected with injection needle respectively, syringe inhales salt water and by the function of needle cylinder injection, and essentially without
Carry out operation switching connector, so that it may realize different function of injection, use is very convenient, considerably increases working efficiency.
Detailed description of the invention
Fig. 1 is the utility model perspective view；
Fig. 2 is the utility model main view.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, the present embodiment is with the utility model
Implemented under premised on technical solution, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this reality
With novel range.
As depicted in figs. 1 and 2, a kind of one-way valve formula three-way connector, including the first connector 1, the second connector 2 and third
Connector 3；Three connectors are respectively connected with two pipelines 4, and the pipeline 4 of three connectors is respectively connected with to constitute one generally
The connecting pipe of triangle；And first connector 1 is circumscribed with bag of saline, second connector 2 is then circumscribed with injection needle,
And the third connector is then circumscribed with syringe；And it is also separately installed in pipeline 4 interconnected between three connectors unidirectional
Valve 5, and the communication direction of the one-way valve 5 between the first connector 1 and the second connector 2 is that the first connector 1 is directed toward the second connector
2；The communication direction of one-way valve 5 between first connector 1 and third connector 3 is that the first connector 1 is directed toward third connector 3；And the
The communication direction of one-way valve between two connectors 2 and third connector 3 is that third connector 3 is directed toward the second connector 2.
Preferably, the one-way valve 5 is respectively mounted the middle position of the pipeline 4 of connection between the knuckles, and institute
The valve piece that the one-way valve 5 stated is set as four valve structures is constituted.
Preferably, first connector 1, the second connector 2 and third connector 3 and pipeline 4 can by bolt arrangement
Disassembly installation.
The present apparatus when in use, when only being injected with injection needle, the bag of saline of the first connector and the second connector
Injection needle be directly connected to injection, and it is to block state, therefore the first connector not can turn on third and connect that third connector, which connects syringe,
Head, but injection needle is led to by two other pipeline and one-way valve and completes injection needle injection.
When inhaling salt water with syringe, the first connector is that the first connector direction third connects with third fittings direction
Head, therefore syringe achievable suction salt water work, and the second connector cannot reach the first connector and the in the effect of one-way valve
Three connectors will not impact injection needle when inhaling salt water.
When using needle cylinder injection, after syringe promotes, due to one-way valve, the syringe positioned at third connector will not
It flows to the first connector but flows at the injection needle of the second connector, and the one-way valve of the second connector and the first connector is reversed
, therefore when the second connector flows into a large amount of salt water, the first connector will not be flowed to and intelligently flowed out by injection needle, syringe note is completed
It penetrates.
The connector of the integral triangle of pipeline structure is separately connected in the present apparatus by three connectors, and corresponding
The equipment connected outside connector is set, and setting is unidirectional in the pipeline of the connection according to the equipment of each connector connection between the knuckles
Valve, while the circulating direction of corresponding setting one-way valve, can the very easily injection of realization injection needle, syringe suction salt water respectively
And the function by needle cylinder injection, and switch connector essentially without operation is carried out, so that it may realize different function of injection,
Using very convenient, working efficiency is considerably increased.
Above-mentioned specific embodiment is a preferred embodiment of the utility model, is not practical new for limiting this
The implementation of type and scope of the claims, it is all made according to content described in present utility model application scope of patent protection it is equivalent
Variation and modification, should be included in the utility model patent application range.
