It also comprises antipricking layer, and antipricking layer is arranged on the transfusion bag body of the both sides, lower end of lower pipe.
The outer tube wall of described lower pipe is also provided with lower pipe bulge loop, and the inwall of upper pipe is provided with the upper pipe groove that can coordinate with lower pipe bulge loop, during cooperation, lower pipe bulge loop is stuck in pipe groove.
Described Pop-top seal cap assembly comprises top cover, draw ring and sealing-plug, and top cover is fixed on the upper surface of pipe, and it is inner that sealing-plug is fixed on pipe, and draw ring is arranged at the upper surface center of top cover.
Described upper inside pipe wall is provided with pipe bulge loop, the lateral wall of sealing-plug is provided with the plug groove that can coordinate with upper pipe bulge loop, during cooperation, upper pipe bulge loop is stuck in plug groove.
The upper and lower surface of described sealing-plug is respectively arranged with the depressed part extended towards sealing-plug center of gravity.
The upper end end face of described lower pipe is provided with and easily stings film.
This utility model has the following advantages:
1, bypass pipe is set on the tube wall of lower pipe, bypass pipe is communicated with transfusion bag body interior, and in bypass pipe, check valve is installed, when needing dosing in infusion process, directly can carry out dosing from bypass pipe, more convenient to operate, and transfusion can not be affected normally carry out.
2, in bypass pipe, check valve is installed, Pop-top seal cap assembly is installed in upper pipe, bypass pipe keeps feed liquor direction unidirectional, can guarantee that bypass pipe does not occur the phenomenon of leakage in infusion process, Pop-top seal cap assembly also can guarantee the sealing property in infusion process, makes whole infusion safety reliable.
3, the upper and lower surface of sealing-plug is respectively arranged with the depressed part extended towards sealing-plug center of gravity, on the one hand, when medical personnel have just started to insert puncture needle, guiding function is played to syringe needle, make the bottom of syringe needle aligned recess, the i.e. center of sealing-plug, on the other hand, the setting of depressed part, make the center of sealing-plug weaker, more easily puncture, reduce puncture force, thus prevent from overexerting, simultaneously, in transfusion bag and lower pipe junction, antipricking layer is set, even if overexert, also not easily puncture, formation twice are insured, guarantee that infusion process is more safe and reliable.
4, be provided with in the upper surface of lower pipe and easily sting film, be on the one hand to medicinal liquid is isolated from the outside before transfusion, medicinal liquid is not contacted with plug, thus avoid the phenomenon that occurs that Pharmaceutical is polluted, the sealing guaranteed after perfusion solution on the other hand, operability in use.
