Wherein: 10, ampoule body; 11, flange; 20, pars papillaris; 30, sealing cover body; 31, opening board; 32, inner cap; 40, flap valve.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, this utility model is described further:
Refer to Fig. 1, this utility model provides a kind of anti-plastic ampoule that backflows that can be used for remaining needle envelope/washing pipe, therein in an embodiment, described ampoule comprises ampoule body 10, be connected in the pars papillaris 20 at ampoule body 10 tops and be sealedly attached to ampoule body 10 tops and described pars papillaris 20 is accommodated to sealing cover body 30 in the inner, sealing lid 30 comprises opening board 31 and is located at the middle inner cap 32 of opening board 31, this inner cap 32 is sheathed on outside described pars papillaris 20, be sealing state, particularly, the top of ampoule body 10 is provided with the flange consistent with the cross section of sealing cover body 30 11, described sealing cover body 30 is connected with these flange 11 imaginary points, be that sealing cover body 30 is not that whole one are tightly connected with the junction of flange 11, but be provided with some breakpoints in opening board 31 junction corresponding with flange 11, this design can guarantee being tightly connected of sealing cover body 30 and ampoule body 10, guarantee that bottle interior liquid and pars papillaris 20 are aseptic, can be easy to open again---during use, only need firmly rotarily open plate 31 just can turn on sealing cover body 30, pars papillaris 20 and ampoule body 10 internal communication, the medicinal liquid being contained in ampoule body 10 flows out via pars papillaris 20, the size of this pars papillaris 20 is consistent with the good size and spaced farapart of existing ordinary syringe front end, can connect common scalp acupuncture interface, thereby carries out medicinal liquid conveying, described pars papillaris 20 is provided with the one-way valve for pars papillaris described in one-way conduction 20 with the junction of ampoule body 10.
In the present embodiment, described one-way valve comprises two flap valves 40, the lateral edges one of this two flap valve 40 connects, the top edge of two flap valves 40 is separated from each other, the feather edge of this two flap valve 40 is connected with the inwall one of the junction of ampoule body 10 with described pars papillaris 20, the lateral cross of two flap valves 40 is triangular in shape, and this vertex of a triangle is pointed to the port of export of pars papillaris 20; This two flap valve 40 adopts flexible material to make, and when medicinal liquid flows outward from ampoule body 10 inside, can promote described flap valve 40, makes the top of two flap valves 40 strut formation outlet, and medicinal liquid flows out smoothly; When medicinal liquid does not flow or be inner to ampoule body 10 from outer flow, this entrance is mutually drawn close and closed to the top of described two flap valves 40 under the promotion of medicinal liquid, thereby can stop medicinal liquid to flow toward ampoule body 10 is interior; Therefore, the structural design of this two flap valve 40 can realize pars papillaris 20 described in one-way conduction, thereby reaches the object that prevents that medicinal liquid from backflowing.
Particularly, whole ampoule is to use the medical plastic of packing vein medicinal liquid to make, and body is transparent, neither too hard, nor too soft during extruding; Separately, the junction of described ampoule body 10 and sealing cover body 30---be that opening board 31 is used harder medical plastic with the coupling part of flange 11, rotatable turning on during use, sealing cover body 30 is taken off, thereby expose described pars papillaris 20, extruding ampoule body 10 bodies are discharged after the interior air of bottle, again this pars papillaris 20 is inserted in to common scalp acupuncture interface end, push ampoule body 10 bodies simultaneously, just the medicinal liquid being loaded in ampoule body 10 just can be pressed into remaining needle inside, convenient to operation, saved the step operating separately with syringe; And the design of one-way valve can guarantee that medicinal liquid can only flow out outward from this ampoule, and can not backflow, thereby there will not be blood reflux phenomenon in the time of can guaranteeing remaining needle tube sealing or washing pipe.
In addition, on the outer wall of described ampoule body 10, be also provided with containing mark line (in figure do not indicate), be convenient to medical personnel control be injected into remaining needle inside medicinal liquid number.
In sum, this utility model by arranging a pars papillaris 20 of planting and coordinating with common scalp acupuncture interface on the basis of traditional ampoule, the outer sealing cover body 30 with opening board 31 being connected with ampoule body 10 that is provided with of pars papillaris 20, guarantee that bottle interior liquid and pars papillaris 20 are aseptic, as long as rotatably unscrew, open plate 31 and can open sealing cover body 30, after the aerofluxus of extruding ampoule body medicinal liquid, get final product union joint sword-shaped needle interface end, extruding body malleation is injected medicinal liquid tube sealing or washing pipe in remaining needle, can save the another operation from the interior extraction medicinal liquid of ampoule body 10 with syringe, simple to operate, convenient, be conducive to improve medical personnel's work efficiency, by one-way valve being set in pars papillaris 20 and the junction of ampoule body 10, can guarantee liquid unidirectional outflow and can not backflowing only, prevent blood backflow.
To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of this utility model claim.
