Specific embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Refer to shown in accompanying drawing 1 and accompanying drawing 2, a kind of arteriopuncture servicing unit, including blood back tubular construction 1 and guiding nook closing memberStructure；Described blood back tubular construction 1 is hollow tubular structure, and one end internal diameter of described blood back tubular construction 1 is thin, in the other endFootpath is thick, forms horn-like structure, and the small-caliber end of described blood back tubular construction inserts the tail end of remaining needle；Described blood return tube knotStructure 1 is made up of transparent plastics material；Described guid needle cored structure includes hand holding handle 21, hard guide wire 22 and soft guide wire23, described hand holding handle 21 is arranged on one end of described hard guide wire 22, and described soft guide wire 23 is arranged on describedHard guide wire 22 the other end, described guid needle cored structure inserted in described blood back tubular construction 1；It is described soft to leadDraw silk 23 and bend curved structure, described hand holding handle 21, hard guide wire 22 and soft guide wire 23 are made up of metal materialIntegrative-structure, and described hard guide wire 22 is provided with scale marker.
The length of described blood back tubular construction 1 is 5cm.
The external diameter of the small-caliber end of described blood back tubular construction 1 is 2.5mm, the heavy caliber end of described blood back tubular construction 1External diameter be 5mm.
The length of described guid needle cored structure is 12cm.
Described scale marker does a scale marker since the tip point of described soft guide wire 22 every 1cm,Totally 10.
The length of described hand holding handle 21 is 1cm.
The length of described soft guide wire 22 is 1cm.
The utility model is suitable for radial artery or arteria dorsalis pedis punctures auxiliary and puts pipe, using through transmission technique.Use ordinary venousRemaining needle penetrates artery, when seeing that tube core afterbody has blood to flow back, extracts metal die, connects blood back tubular construction 1, and slow rollback is stayedPin is put, when blood back tubular construction 1 has blood to flow back and flow back unobstructed, guid needle cored structure is inserted, on observation guid needle cored structureScale, after soft guide wire 22 enters 1cm in arteries, you can push remaining needle and enter artery, extracts guiding nook closing member knotStructure, punctures successfully.
In description of the present utility model, it is to be understood that term " one end ", " other end ", " internal diameter ", " tail end "," interior ", " on ", " length ", the orientation of the instruction such as " external diameter " or position relationship be based on orientation shown in the drawings or position relationship,It is for only for ease of description the utility model and simplifies description, must has rather than the device or element for indicating or imply meaningSpecific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
In the utility model, unless otherwise clearly defined and limited, term " setting ", " insertion ", " connection ", " putEnter " etc. term should be interpreted broadly, for example, it may be fixedly connected, or be detachably connected, or integrally；Can beMechanically connect, or electrically connect；Can be joined directly together, it is also possible to be indirectly connected to by intermediary, can be twoThe connection of element internal or two interaction relationships of element, unless otherwise clearly restriction.For the common skill of this areaFor art personnel, concrete meaning of the above-mentioned term in the utility model can be as the case may be understood.
In the utility model, unless otherwise clearly defined and limited, fisrt feature second feature " on " can beFirst and second feature directly contacts, or the first and second features pass through intermediary mediate contact.
In sum, whether the utility model blood return tube has sufficient length, be easy to observation blood back unobstructed, to prove remaining needleWhether in arteries, and blood back is unlikely to quickly to gush out and pollute；Blood back bore is front fine and rear thick into horn-like, favorablyEnter in remaining needle in soft guiding nook closing member；Guiding nook closing member indicates scale, is easy to judge whether nook closing member enters arteries, becauseAnd it is applied to the remaining needle of different length model；Guiding nook closing member front end is soft flexible metal material, it is to avoid insert remaining needleWhen penetrate blood vessel.
Preferred embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited,The equivalent structure transformation that every utilization the utility model description is made, or it is directly or indirectly related with other are attached toThe technical field of product, is similarly included in scope of patent protection of the present utility model.
