Abstract
The utility model relates to a connection base structure for injection. The connection base structure for the injection comprises a connection base body, the connection base body is provided with a connection port connected with an injection head of a syringe, a connection head connected with an injection piece and a connection channel connecting the connection port and the connection head, a check valve is arranged in the connection channel, and the injection head of the syringe opens or closes the check valve. According to the connection base structure for the injection, the check valve is arranged in the connection base body and opened and closed through the injection head of the syringe, the bidirectional checking function on liquid medicine and sampling is achieved, safety and hygiene are achieved, the hidden danger of virus spreading is reduced, and the connection base structure for the injection is simple and suitable for various injection devices.
Description
Technical field
this utility model relates to medical instruments field, particularly relates to a kind of connecting base structure of injection.
Background technology
in medical procedure, injecting liquid drug need to be sampled to diagnose or treat in patient body or to patient, and the syringe adopting is mainly syringe.As shown in Figure 1: syringe comprises bobbin 10, piston 11, and the end of bobbin 10 has injection head 100.In the time injecting, by injection head 100 being connected to entry needle or tube for transfusion is injected or samples.But at present completely easily there is back liquid or water clock while extracting injection head 100 when injecting or sampling, have the hidden danger of virus disseminating.
Summary of the invention
the purpose of this utility model is to provide a kind of connecting base structure of injection.
for achieving the above object, the technical solution adopted in the utility model is:
a kind of connecting base structure of injection, comprise a Connection Block body, described Connection Block body has the connector that is connected with the injection head of syringe, is connected with the union joint of injection member and is connected described connector and the interface channel of union joint, in described interface channel, be provided with check valve, described check valve is opened or closed to the injection head of described syringe.
preferably, described injection member is syringe needle.
preferably, described injection member is tube for transfusion.
preferably, described check valve has an elastomeric element, on described elastomeric element, offers and can shrink closed hole.
because technique scheme is used, this utility model compared with prior art has following advantages:
this utility model by arranging check valve in Connection Block body, injection head by syringe is opened, is closed, and medicinal liquid, sampling is played to the effect of dual check, safety and sanitation, reduce the hidden danger of virus disseminating, and be simple in structurely applicable to all kinds of injection devices.
Brief description of the drawings
the structural representation that accompanying drawing 1 is syringe;
the structural representation (injection member is syringe needle) that accompanying drawing 2 is embodiment mono-;
accompanying drawing 3 is structural representation of the present utility model (injection member is tube for transfusion);
accompanying drawing 4 is this utility model and syringe connection diagram.
wherein: 10, bobbin; 100, injection head; 11, piston; 2, Connection Block body; 20, connector; 21, union joint; 22, interface channel; 3, check valve; 40, syringe needle; 41, tube for transfusion.
Detailed description of the invention
below in conjunction with drawings and Examples, this utility model is further described:
embodiment mono-:
the connecting base structure of a kind of injection as shown in Figure 2, comprise a Connection Block body 2, Connection Block body 2 has connector 20, the union joint 21 that is connected with injection member being connected with the injection head 100 of syringe and is connected the interface channel 22 of connector 20 and union joint 21, in interface channel 22, be provided with check valve 3, open or close this check valve 3 by the injection head 100 of syringe.
in the present embodiment: injection member is syringe needle 40, and the structure of check valve 3 is: it has an elastomeric element, offers and can shrink closed hole on elastomeric element.
as shown in Figure 4: in use, the injection head of syringe 100 is inserted in the connector 20 of Connection Block body 2, exert pressure and make it the hole through on elastomeric element by manpower, due to elastic shrinkage, the surrounding of injection head 100 is surrounded by elastomeric element, can not produce any leakage; Piston 11 is exerted pressure, the medicinal liquid in bobbin 10 is injected to interface channel 22 by injection head 100, or piston 11 is carried out to evacuation, take a blood sample and gather; After injection or sampling, the injection head of syringe 100 is extracted out from elastomeric element, hole is shunk closed, avoids refluxing.
embodiment bis-:
one is as shown in Figure 3 penetrated with connecting base structure, and the present embodiment and embodiment mono-are basic identical, and difference is: injection member is tube for transfusion 41.
the application opens or closes this check valve 3 by the injection head 100 of syringe, from traditional to open check valve 3 by fluid pressure different: in the time sampling (as blood drawing), blood pressure does not have enough large pressure conventionally to be washed check valve 3 open automatically, is only suitable for having the injection that external force is exerted pressure; The application is a kind of two-way non-return, is applicable to injection and sampling.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to this utility model spirit change or modify, within all should being encompassed in protection domain of the present utility model.
