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.
