Abstract
The invention relates to a transfusion container sealing cover with a side-pull type transfusion pipe and a drug feeding pipe, belonging to a liquid inlet and outlet pipeline of a transfusion bottle (bag) and a pipeline sealing device. The side-pull type transfusion pipe and the drug feeding pipe are fixed on the same outer surface of a cover body basically in parallel; the side-pull type transfusion pipe comprises a side-pull type transfusion needle guide pipe and a sealing sheet; the drug feeding pipe comprises a drug feeding pipe body, a gasket, a gasket fixing ring and an easily-pull cover, wherein the gasket is arranged on a gasket membrane, and the gasket fixing ring is arranged on the gasket; the cover body comprises a cover bottom sheet, a hollow cylinder and a cylinder welding ring, wherein the hollow cylinder is formed by connecting the side walls of the cover, and the cylinder welding ring is formed by outwards extending the edge of the hollow cylinder. The invention has the advantages that a double-pipe connector can realize two functions of drug feeding and transfusion, and the transfusion container sealing cover has difficult scrap dropping and easy puncture in the process of transfusing puncture; and the transfusion container sealing cover also has lower production cost.
Description
Technical field
The invention belongs to medical infusion packing technique field, particularly have the two-tube transfusion container sealing cover of dosing and two kinds of functions of transfusion.
Background technology
Transfusion container sealing cover requires to have the transfusion function, preferably also the dosing function should be arranged.
The closing device of existing plastic infusion bottle or transfusion bag all is to come sealing bottles (bag) mouth with the combined plastic seal cover, and this seal cover is made up of three parts: inner cap, enclosing cover and place inner cap and enclosing cover between pad (like the polyisoprene pad).When transfusion,, contact the back with medicinal liquid and realize transfusion with resin needle penetration pad and inner cap.Because pad and inner cap are thicker, in piercing process, pad and inner cap all are prone to bits, often cause medicinal liquid contaminated; Penetration Resistance is big, and is not easy to operate; In addition, the production cost of this combined plastic seal cover is also higher.
Summary of the invention
The purpose of this invention is to provide a kind of two-tube conjuncted transfusion container sealing cover that side-pull type transfusion pipe and chemical feed pipe are arranged, the sealing lid can be realized dosing, two functions of transfusion.In the vein puncture process, be difficult for falling bits, be easy to puncture; And the production cost of this transfusion container sealing cover is also lower.
Structure of the present invention is:
The transfusion container sealing cover of band side-pull type transfusion pipe and chemical feed pipe comprises side-pull type transfusion pipe 1, chemical feed pipe 2 and lid 3, it is characterized in that: both are fixed on the same one side of thin slice 35 appearances at the bottom of lid 3 lids side-pull type transfusion pipe 1 and chemical feed pipe 2 substantially parallelly; Lid 3 is used for being tightly connected with the eck of infusion bottle (bag), synthetic complete infusion bottle (bag).
The logical integrative-structure in Kongxiang in side-pull type transfusion pipe 1 is connected to become with lid 3; Side-pull type transfusion pipe 1 is made up of side-pull type infusion needle guide tube 4 and diaphragm seal 7 two parts; The hollow cross-section of side-pull type infusion needle guide tube 4 is provided with seal dissepiment 5, is sealed with diaphragm seal 7 on the layback sealing of tube ring 6; Lateral wall near the side-pull type infusion needle guide tube 4 of diaphragm seal 7 is provided with easy-to-draw circle 8, and the position of easy-to-draw circle 8 is between seal dissepiment 5 and diaphragm seal 7, and other sidewall position of the wall ratio side-pull type infusion needle guide tube 4 of easy-to-draw circle 8 is thin, connects pulling-on piece 9 on the easy-to-draw circle 8; When transfusion is used, hold pulling-on piece 9 and firmly pull off easy-to-draw circle 8 and diaphragm seal 7, the interior sky of side-pull type infusion needle guide tube 4 exposes and is used to insert transfusion needle.Transfusion needle puncture through seal barrier film 5 back medicinal liquids get into transfusion needle.
The logical integrative-structure in Kongxiang in chemical feed pipe 2 is connected to become with lid 3; Chemical feed pipe 2 is made up of dosing body 21, pad 11, spacers ring 17,10 4 parts of easy-open lid; The opening inner surface of dosing body 21 is provided with sky 12 in the depression, and empty 12 bottom is provided with pad barrier film 22 in the depression; Pad barrier film 22 is provided with pad 11, and pad 11 is provided with spacers ring 17; Easy-open lid 10 comprises easy-to-draw spill lid 13 and pull-tab 14, is easy-to-draw diaphragm seal 15 in the middle of the easy-to-draw spill lid 13, and easy-to-draw diaphragm seal 15 peripheries are provided with easy-to-draw impression, and pull-tab 14 is connected above the easy-to-draw diaphragm seal 15; The welded edge 23 of easy-to-draw spill lid 13 is tightly connected with interior empty 12 the groove circle welding ring 24 of depression; Spacers ring 17 is a circulus.Spacers ring 17 in the chemical feed pipe 2 is between pad 11 and welded edge 23; Welded edge 23 is pressed in spacers ring 17 above the pad 11; Make pad 11 when dosing is needled into and pull out; The problem that pad 11 can not produce displacement, can not produce the gap, can not gapped long-pending medicine produces, and the sanitary standard of chemical feed pipe 2 is improved greatly.
Following structure is a preferred form of the present invention:
The thickness of pad 11 is 4.0-6.0mm; Pad barrier film 22 thickness are 0.3-1.0mm;
Easy-to-draw circle 8 can also be the annular ring between the line that is interrupted that two substantially parallel depressions are gone up in the side-pull type infusion needle guide tube 4 walls outside, and cup depth is less than 3/4 of side-pull type infusion needle guide tube 4 wall thickness.
Advantage of the present invention:
The present invention is a kind of two-tube conjuncted transfusion container sealing cover with side-pull type transfusion pipe and chemical feed pipe, can realize dosing, two functions of transfusion, compares with traditional seal cover, in the vein puncture process, is difficult for falling bits, is easy to puncture; And the production cost of this transfusion container sealing cover is also lower.
The easy-open lid of chemical feed pipe and interior empty being tightly connected of depression can guarantee that chemical feed pipe water when sterilization can not infiltrate, and inner any position is in aseptic condition all the time, before in infusion vessel, injecting or taking out medicinal liquid, must not carry out disinfection to the pad outer surface.Sky makes falling bits and can not getting in the infusion vessel of pad in the depression, has got rid of chemical feed pipe and has fallen bits and pollute.The easy-to-draw opening structure of easy-open lid can be simplified transfusion operation.
The present invention is provided with the spacers ring between pad and easy-open lid; On the one hand pad is played fixation; Pad can not become flexible after when dosing, drawing back easy-to-draw diaphragm seal, makes on the other hand to keep rational distance between pad and the easy-open lid, and pad can not destroyed by high temperature when the welding easy-open lid.
With diaphragm seal simple in structure to side-pull type infusion needle guide tube sealing.
