Description
Technical field
The system that the utility model relates generally to intravenous (IV) conveying, can be by the system directly by fluid
It is delivered to the vascular system of patient.More particularly, the utility model relates to a kind of tool, there are two the positive pressure needle-free connectors of pre-terminated
IV conduit.
Background technique
Therapeutic treatment is generally included will the medical fluid such as saline solution or liquid medicine using intravenous (IV) conduit
It is conveyed to patient, which is connected to fluid source, such as IV bags by Needleless connector.Needleless connector, which usually has, to be met
" female Luer " of International Standards Organization (ISO) standard.
There is the IV conduit of the various Needleless connectors with pre-terminated in the market.Fig. 1 shows a kind of existing IV conduit
100, there are two the non-positive pressure needle-free connectors of pre-terminated for tool.IV conduit 100 has several components, comprising: conduit tube component 101,
Needle assemblies 102, extension 103, clip 104, Y shape adapter 105 and two non-positive pressure needle-free connectors 106.
It is using the problem of non-positive pressure needle-free connector, when IV conduit is disconnected from fluid source (for example, IV bags)
When, blood may be pulled in conduit cavity.If the blood stays in conduit cavity, which may be condensed into blocks and cause
There is health problem in patient.
Fig. 2 shows another existing IV conduits 200.The structure of IV conduit 200 is similar with the structure of IV conduit 100,
It include: conduit tube component 201, needle assemblies 202, extension 203, clip 204 and Y shape adapter 205.IV conduit 100 and IV conduit
Difference between 200 is that IV conduit 200 includes the positive pressure needle-free connector 206 and an end cap 207 of a pre-terminated.
The IV conduit 200 of positive pressure needle-free connector 206 with a pre-terminated can contribute to anti-Hemostatic Oral Liquid and enter conduit
End, thus avoid blood clotting it is blocking/pollution and therefore caused by blood infection.However, IV conduit 200 only has one
It is connected to the positive pressure needle-free connector of the first branch of Y shape adapter 205 in advance, and the second branch of Y shape adapter 205 is by end cap
207 are covered.In this case, if needing to carry out using the second branch of Y shape adapter under emergency medical scenario
Drug conveying, then need for end cap to be changed to another connector, this may be time-consuming, and may during replacing connector
Cause to infect.In addition, due to pre- the first branch for being connected to positive pressure needle-free connector that only used Y shape adapter, Y shape adapter
The second branch with end cap may still remain blood or drug, and this is undesirable.
