Description

Infusion vessel is reinforced composite cover with polypropylene bivalve Easy-folding inner cap

Technical field:

This utility model relates to the medical package field, is specifically related to the improvement that a kind of infusion vessel is reinforced composite cover with polypropylene bivalve Easy-folding inner cap.

Background technology:

Existing large transfusion flexible bag or the wrapping Welding type composite cover of bottle have two kinds of forms, one is comprised of enclosing cover, Nei Sai and inner cap, covered draw ring outward, thereby during use, draw ring need be drawn on firmly enclosing cover is pulled open together with the draw ring connecting portion expose in the hole of threading a needle beyond the Great Wall, in order to liquid medicine is injected in bag or bottle, or the liquid medicine in bag or bottle is injected to people's blood by transfusion device.The Main Function of interior plug be when injection medicine can not wear out because of interior cover needle tubing and ooze out outside transfusion bag or bottle.But because place and the time of making up a prescription in use with to patient infusion are all different, while entering to infuse to disease, Yin Neisai is exposed a regular hour, likely produce the risk of cross-contamination, disinfect in alcohol therefore must internally fill in exposed part before injection, increased the cost of sterilization while therefore infusing.Another kind of existing two easy-to-fold caps, can tear at twice, while making up a prescription, half torn, and second half still seals with enclosing cover, during transfusion, again it is torn and gets final product.

Can reduce the cost of sterilization so in use, interior plug changes little strip or the circle of changing into, reduces material usage, reduces costs.But plug is left the row problem for strip in the composite cover of this structure: 1. in strip, plug is high to the cutting dies requirement during excision slitter edge in manufacturing process, has increased the cost of manufacture of interior plug; 2. strip is when syringe needle injects in bag or bottle by the hole of threading a needle, and the strip plug easily produces displacement in composite cover, affects like this sealing property of whole composite cover; In the composite cover of this structure, plug is left the row problem for circle: plug is easily fallen in bag or bottle when inserting syringe needle.

Close the lid and often easily be out of shape when high-temperature sterilization or subside in addition in prior art, cause coordinating between inner cap and plug and enclosing cover to produce distortion, the fit clearance distortion easily occurs and strengthen the water inlet caused, and after puncture the risk of leakage drug.

The utility model content:

This utility model provides infusion vessel to reinforce composite cover with polypropylene bivalve Easy-folding inner cap, in the lid manufacture process cost low, two thread a needle and mutually do not pollute when hole is used, inside close the lid and be difficult for distortion and subside, and not affected by external force during the syringe needle puncture and occur that plug moves left and right or fall into the phenomenon in bottle.

Technical problem of the present utility model is to solve by following technical scheme, provide infusion vessel to reinforce composite cover with polypropylene bivalve Easy-folding inner cap, comprise in inner cap, enclosing cover and closing the lid and for the plug of transfusion and the time puncture use of making up a prescription, it is characterized in that, closing the lid in described is provided with a support rim.

Further improve and be: the bottom surface of the middle part that closes the lid in described is provided with one to down-open recess.

Further improve and be: the groove bottom correspondence that closes the lid in described be provided with one with groove vertical direction reinforcement.

Further improve and be: the upper support that inside closes the lid boss is provided with the positioning boss fastened with the plug bottom.

Further improve and be: described plug designs for integral type, and plug adopts two dolioform structures of circular composition, and the enclosing cover top of composite cover is provided with detent and the positioning boss fastened with plug.

Further improve and be: described dolioform structure mid portion adopts the concave surface fit structure, and described composite cover enclosing cover upper part and plug closely cooperate, and ring-type detent and positioning boss, positioning boss are arranged on plug.

Further improve and be: plug is provided with site of puncture.

Further improve and be: dolioform plug structure and the dolioform structure of enclosing cover cooperatively interact closely fully, make the horizontal left and right displacement of plug almost nil, plug closely cooperate locate more accurate.

The present embodiment provides infusion vessel to reinforce composite cover with polypropylene bivalve Easy-folding inner cap, comprise inner cap, enclosing cover and the plug of puncture use for transfusion and while making up a prescription, described plug designs for integral type, plug adopts two dolioform structures of circular composition, described dolioform structure mid portion adopts the concave surface fit structure, move left and right fit clearance while making the plug puncture and reduce to minimum, and the enclosing cover top of composite cover is provided with detent and the positioning boss fastened with plug, and plug is provided with site of puncture; Described composite cover enclosing cover upper part and plug closely cooperate, and the top that inside closes the lid is provided with the positioning boss fastened with the plug bottom, plug are guaranteed consistent with the center of exterior and interior cover, can not be subject to the impact of external force and produce skew; Adopt an orbicular projection to coordinate with the full circle shape concave surface of plug closely, guaranteed accuracy and the compactness of location; It is protruding that the boss inside closed the lid is arranged with a support outward, the boss of this part is very important, the one, play the effect of support can to the first muscle, the 2nd, play the effect of reduction deflection, produce larger distortion when preventing that when the high temperature sterilize temperature difference is larger and changing, have a strong impact on cooperation and the sealing of product, also guaranteed deflection and the flatness on whole plane simultaneously; With cover corresponding part easy to break be the inner concave shape cylindrical structure, ring-type detent and positioning boss, positioning boss are arranged on plug; The upper surface that inside the closes the lid position below corresponding with plug is provided with boss; The bottom surface of middle part of closing the lid in described is provided with one to down-open recess; The groove bottom correspondence that closes the lid in described be provided with one with groove vertical direction reinforcement, with the problem on deformation closed the lid in guaranteeing after high temperature sterilize, solved.

The beneficial effects of the utility model are: this utility model provides infusion vessel to reinforce composite cover with polypropylene bivalve Easy-folding inner cap, in the lid manufacture process cost low, two thread a needle and mutually do not pollute when hole is used, inside close the lid and be difficult for distortion and subside, and during the syringe needle puncture, not affected by external force and occur that plug moves left and right or fall into the phenomenon in bottle, risk and defect that the existing market product exists have been improved, the simultaneously also more perfect correlation function of product, performance are that product has safety more.
