In addition, in infusion process, usually need patient can not arbitrarily movement, because patient is in moving process, medicinal liquid may be caused to reflux, and even venous backflow be in transfusion bag, and transfusion can not normally be carried out, and this often brings larger inconvenience to patient.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of medicinal liquid that prevents to reflux, tear the reverse-filling polypropylene infusion bag with teared cap that is simple to operate and good sealing effect.
The purpose of this utility model is achieved through the following technical solutions: the reverse-filling polypropylene infusion bag with teared cap, comprise transfusion bag body, mouthpiece, teared cap assembly and reverse-filling mechanism, one end of mouthpiece is communicated with transfusion bag body interior, and the outer wall of mouthpiece and transfusion bag body are tightly connected, teared cap assembly is arranged at the other end of mouthpiece, described reverse-filling organization establishes is in mouthpiece
Described teared cap assembly comprises inner cap and enclosing cover, inner cap cooperation is installed in the mouthpiece mouth of pipe, enclosing cover is covered on outside the mouthpiece mouth of pipe, the arranged outside of mouthpiece tears ring, tear ring and be provided with multiple junction point respectively and between enclosing cover and mouthpiece sidewall, inside enclosing cover, roof center is provided with connecting portion and elastic card buckle portion, connecting portion is arranged along the axis of enclosing cover, elastic card buckle portion is arranged along the radial direction of enclosing cover, connecting portion is connected with elastic card buckle portion, the top of inner cap offers the cavity that can coordinate with connecting portion and elastic card buckle portion, connecting portion and elastic card buckle portion are placed in described cavity,
Described reverse-filling mechanism comprises drain post and non-return plug, drain post is the tub structure that one end has opening, the opening of drain post is connected with the inner wall sealing of mouthpiece, and drain post offers many fluid seams along its axis direction, and non-return plug is slidably installed in drain post.
The quantity of described junction point is more than three or three, and described junction point distributes along the even circumferential of enclosing cover.
The junction of described mouthpiece and drain post is cone structure, and described non-return plug is also provided with non-return towards the side of described cone structure, and non-return is the conical surface consistent with the tapering of described cone structure.
This utility model has the following advantages:
1, reverse-filling mechanism is set in mouthpiece, when transfusion bag overturns, the cone structure of non-return plug to mouthpiece under the effect of the medicinal liquid of self gravitation and backflow moves, and the conical surface of the conical surface of non-return plug and mouthpiece is formed and seals, thus prevent medicinal liquid from refluxing, bring larger convenience to patient.
2, on teared cap assembly, arranging two tears a little, one of them is arranged between enclosing cover and mouthpiece, another is arranged between enclosing cover and inner cap, these two to tear dot structure simple, tear conveniently, and then can tear second a little and tear a little tearing tearing between enclosing cover and mouthpiece, whole operating process links up.
3, inner cap and enclosing cover are set on mouthpiece, during storage, inner cap and enclosing cover play sealing function simultaneously, when in infusion process, tear two and tear a little, inner cap is still retained in mouthpiece, sealing can be formed, that is store in transfusion bag or be provided with hermetically-sealed construction in infusion process, can effectively prevent medicinal liquid from being polluted, good sealing effect.
