Utility model content
The purpose of this utility model is to solve the drawbacks described above that existing calparine cap exists, it is provided that the calparine cap structure of a kind of improvement, arranges cap on calparine cap; place calparine cap repeatedly, repeated localised puncture use during pollution; easy to use, protective effect is good, does not comes off.
In order to achieve the above object, this utility model adopts the following technical scheme that: the calparine cap structure of a kind of improvement, including three way cock's main body and the calparine cap being arranged on a joint of described three way cock's main body, it is provided with cap on described calparine cap, described calparine cap includes the described joint connection of joint connection, injection part and connection and the connecting neck portion of described injection part, and described cap includes the main cap hiding described injection part and the described connecting neck portion being extended to reach calparine cap from described main cap the extension coordinated with described connecting neck portion.
Calparine cap, by the cap adaptive with calparine cap, is protected by technique scheme, prevents the pollution during using, and cap carries out card by joint connection and connecting neck portion and fastens, good fixing effect.
As preferably, the diameter of described connecting neck portion, less than the diameter of described injection part, is possible to prevent to pollute.
As preferably, described injection part is provided with boss with the junction of described connecting neck portion；The extension of described cap is provided with the scrobicular ring of correspondence, strengthens preventing polluting effect.
As preferably, described joint connection forms connecting platform in the end of described connecting neck portion.
As preferably, the concave surface of described connecting platform forms the protector around described connecting neck portion, and the end of described extension extends in described protector.
As preferably, the inner chamber top of described cap is provided with inverted draw cut, is provided with removable aseptic cotton in described inverted draw cut.
As preferably, the top of described cap is provided with the edge portion beyond described cap circumferential edge edge.
By implement technique scheme, this utility model have the advantage that this utility model can effectively prevent calparine cap use during pollution, easy to use, good fixing effect, simple in construction.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of this utility model one embodiment；
Accompanying drawing 2 is the enlarged diagram of calparine cap in accompanying drawing 1；
Accompanying drawing 3 is the schematic diagram of calparine cap in another embodiment of this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, this utility model is described in further detail.
Embodiment 1:
As shown in accompanying drawing 1,2, the calparine cap structure of a kind of improvement, for remaining needle, including three way cock's main body 10, three way cock is respectively communicated with infusion tube, positive pressure connector box calparine cap 20.Wherein, calparine cap 20 being provided with the cap 30 can opened at any time, close, when needs are injected by calparine cap 20, open cap 30, remaining time covers tightly cap 30, prevents from polluting.Calparine cap 20 includes joint connection 201, the injection part 202 being available for puncture injection and the connecting neck portion 203 of jointing connecting portion 201 and injection part 202, so, the cap 30 of matched use includes hiding the main cap 301 of injection part 202 and the connecting neck portion 203 being extended to reach calparine cap 20 from main cap 301 extension 302 coordinated with connecting neck portion 203.The diameter of connecting neck portion 203, less than the diameter of injection part 202, can strengthen preventing polluting effect.It addition, be provided with boss 204 in the junction of injection part 202 with connecting neck portion 203；Cap 30 extension is provided with the scrobicular ring 303 of correspondence, strengthens preventing polluting effect further.Joint connection 201 forms connecting platform 2011 in the end of connecting neck portion 203; the concave surface of connecting platform 2011 forms the protector 2012 around connecting neck portion 203; the end of extension 302 extends in described protector 2012; such design, is for ensureing that calparine cap 20 is the most contaminated.
Embodiment 2:
As shown in Figure 3, the calparine cap structure of a kind of improvement, for remaining needle, including three way cock's main body 10, three way cock is respectively communicated with infusion tube, positive pressure connector box calparine cap 20.Wherein, calparine cap 20 being provided with the cap 30 can opened at any time, close, cap 30 can separate with calparine cap 20, independent, it is also possible to is connected on calparine cap 20 by connecting hinge.When needs are injected by calparine cap 20, opening cap 30, remaining time covers tightly cap 30, prevents from polluting.Calparine cap 20 includes joint connection 201, the injection part 202 being available for puncture injection and the connecting neck portion 203 of jointing connecting portion 201 and injection part 202, and the top of cap 30 is provided with the edge portion 305 beyond cap 30 circumferential edge edge, facilitates opening of cap 30.The cap 30 of matched use includes hiding the main cap 301 of injection part 202 and the connecting neck portion 203 being extended to reach calparine cap 20 from main cap 301 extension 302 coordinated with connecting neck portion 203.The diameter of connecting neck portion 203, less than the diameter of injection part 202, can strengthen preventing polluting effect.It addition, be provided with boss 204 in the junction of injection part 202 with connecting neck portion 203；Cap 30 extension is provided with the scrobicular ring 303 of correspondence, strengthens preventing polluting effect further.Joint connection 201 forms connecting platform 2011 in the end of connecting neck portion 203; the concave surface of connecting platform 2011 forms the protector 2012 around connecting neck portion 203; the end of extension 302 extends in described protector 2012; such design, is for ensureing that calparine cap 20 is the most contaminated.The inner chamber top of cap 30 is provided with inverted draw cut 304, is provided with the aseptic cotton that can regularly replace in inverted draw cut 304, can carry out disinfection the calparine cap 20 after puncturing simultaneously.
