Description
Technical field
The utility model relates to a kind of double-colored infusion connector integral caps of transfusion flexible bag.
Background technique
Medical large transfusion is one of important species of pharmaceutical industry, and big product of being infused is generally divided into three according to its packaging material
Major class: glass bottle, plastic bottle and soft bag.Traditional vial is lacked since its quality weight, cracky, not Portable belt and environmental pollution are big etc.
The appearance of point, plastic bottle and soft bag then compensates for these disadvantages of vial, and is also equipped with can be with effective recycling the advantages of, because
This, the big plastic for being infused product packaging becomes main trend, for example, the use ratio in the U.S. is up to 90%, Europe is
70%, India also reaches 50% or more.At home, the policy based on carry out in an all-round way medical insurance and reinforcement community medicine construction, it is big defeated
Liquid will be stepped up as clinically used basic medication, big infusion products usage amount, it is contemplated that market capacity, which is up to, to be needed in year
About 8,000,000,000 bottles (bag), the infusion of current developed country is basically reached using horizontal, thus, use safer more environmentally friendly plastic bottle and soft
Bag transfusion package will be where promoting the trend of Medicare.
Packing Infusion Used Large Plastic Bottle packaging is usually made of two parts such as bottle body, combined caps, and packed in flexible pouchy is then by soft bag, interface, group
The three parts such as closing lid composition, and common combined cap is then made of three parts such as outer cover, inner cover, rubber mat.For rubber mat, mesh
The preceding country mostly uses rubber as raw material greatly, but the drawbacks of be easy to produce fragmentation due to rubber, thus, external some enterprises
Gradually in the rubber plug rubber mat for releasing elastomeric material, such as the medicinal TPE rubber mat of GLS Corp., the U.S.；Japanese big tomb TPE series glue
Pad；The thermoplastic elastomer (TPE) transfusion rubber plug etc. of WEST company, the U.S., thus, thermoplastic elastomer (TPE) is referred to as " third generation synthesis rubber
Glue ", abbreviation TPE (Thermoplastic Elastomer), is used in medical packaging industry, shows its distinctive dustless, nothing especially and falls
The characteristic of bits, nontoxic, resistance to general chemicals, so currently, domestic related scientific research studies carefully institute, medical packaging material enterprise is also actively being unfolded
The research and development and application of medicinal TPE material.
As depicted in figs. 1 and 2, the prior art is that a soft bag is needed with an interface and a set of combined cap, a set of combination
Lid need to be formed by tri- a PP outer cover 1-1, a PP inner cover 1-3, rubber pad 1-2 component assemblies, these three parts are again
It needs mating corresponding production equipment, technique respectively and assembles equipment to produce, the disadvantage is that process is various, complicated, qualification rate
Low, equipment investment is more, takes up a large area, the wasting of resources.
After processing part PP outer cover 1-1, PP inner cover 1-3 and interface 1-4 respectively with injection molding, with sulfidization molding plus
Work goes out rubber pad 1-2；The production process of rubber pad 1-2 are as follows: ingredient → mixing → mixing → calendering → cut-parts → vulcanizes → picks
→ punching → prerinse → extracting sulphur → cleaning → packaging, process is various, complicated, and qualification rate is low, and equipment investment is more, occupied area
Greatly, the wasting of resources, and environmental pollution is also big.After producing and processing out single product respectively, PP outer cover 1-1, PP inner cover 1-3
It needs first to do primary group lid process with rubber pad 1-2, first rubber pad 1-2 is pressed into PP outer cover 1-1, then PP inner cover 1-3 is pressed
Enter in PP outer cover 1-1, be assembled into combined cap, the combined cap combined is combined with infusion bottle again, by interface 1-4 and adds good liquid medicine
7 welding of transfusion flexible bag forms the soft bag with interface；Finally combined cap and the soft bag with interface are welded together.This
Set combined cap the weight of material, matched equipment, product production run on put into very big cost, be finally completed in product
The operation by multiple production process is needed, each operation has certain defect rate, therefore combined cap product not only closes at present
Lattice rate is low, but also there is the risks repeatedly polluted；Next is on rubber plug or uses rubber material, made of rubber material
Product is easy to produce exfoliation phenomenon in multiple acupuncture course, and generated rubber exfoliation will directly fall into liquid medicine, and there is rubbers
Glue exfoliation flows into the danger of human body with liquid medicine.Combined cap often occurs rubber pad in clinical use and is needled into infusion appearance by resin
Phenomenon in device, safety are lower.

Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
Embodiment 1
As in Figure 3-5, the double-colored infusion connector integral cap of the transfusion flexible bag of the utility model, including 2 He of plastic cover
Thermoplastic elastomer (TPE) rubber mat 1, plastic cover 2 and thermoplastic elastomer (TPE) rubber mat 1 use dual-color forming technology single injection-molded.Modeling
Expect that 2 lower end of lid is the interface for connecting with transfusion flexible bag, plastic cover 2 is in hollow cylinder structure, and inner cavity is by every liquid film 4
It is divided into upper cavity and lower chamber, thermoplastic elastomer (TPE) rubber mat 1 is placed in upper cavity.The thermoplastic elastomer (TPE) rubber mat 1 with it is upper
The inner sidewall of cavity and the fitting every 4 upper surface of liquid film are connected.
The plastic cover 2 is PP material, and thermoplastic elastomer (TPE) rubber mat 1 is thermoplastic elastomer (TPE) (TPE) material.It is described
Thermoplastic elastomer (TPE) rubber mat 1 upper surface be plane, thermoplastic elastomer (TPE) rubber mat 1 have one thickening part, it is described
The part of thickening is located at the middle part of thermoplastic elastomer (TPE) rubber mat 1, and the lower part of thermoplastic elastomer (TPE) rubber mat 1 is segment-shaped, thermoplasticity
The middle part of elastomer rubber mat 1 is thicker than the edge of thermoplastic elastomer (TPE) rubber mat 1 to increase screen resilience.
The upper surface of the thermoplastic elastomer (TPE) rubber mat 1 is plane, and the middle part of lower surface is that longitudinal section is arc-shaped
Curved surface, the corresponding center of circle of the circular arc are located at the top of the curved surface.The middle part of 1 lower surface of thermoplastic elastomer (TPE) rubber mat is spherical.
When the thermoplastic elastomer (TPE) rubber mat 1 is needled to form pin hole, around the lower surface pin hole of thermoplastic elastomer (TPE) rubber mat 1 by
When the pressure of medical fluid, it can gather in transfusion flexible bag to pin hole, so that the pin hole on thermoplastic elastomer (TPE) rubber mat 1 be made to close
It closes.
The middle part of the lower surface of the thermoplastic elastomer (TPE) rubber mat 1 is lower than the edge of lower surface, in infusion, infusion
Soft bag is inverted with double-colored infusion connector integral cap, and when being infused defeated most, the resin pin hole on thermoplastic elastomer (TPE) rubber mat 1 exposes at first
Liquid level also can avoid pulling out needle leakage.
It is described every liquid film 4 be it is spherical, longitudinal section be it is arc-shaped, the corresponding center of circle of the circular arc is located at the upper of the curved surface
Side is that the contact of liquid medicine and elastomeric body 3 is isolated every the effect of liquid film 4.
