Description
Technical field
This utility model belongs to the medical infusion bags accessory, particularly can with the pipeline and the duct sealing device of the turnover liquid of transfusion bag thin film smooth connection.
Background technology
The accessory of existing transfusion bag comprises body seat (interface) and two parts of seal cover, earlier body seat and plastic sheeting heat seal is welded when the production transfusion bag, seal cover and the heat seal of body seat is welded after pouring into medicinal liquid again.This manufacture method has increased welding sequence one, must increase welding post on bag making, filling and sealing machine, thereby increase the device fabrication cost, and easily pollute when producing transfusion.Existing seal cover is made up of three parts again: inner cap, enclosing cover and place inner cap and enclosing cover between rubber sheet gasket (as the polyisoprene pad).When transfusion,, contact the back with medicinal liquid and realize transfusion with resin needle penetration rubber sheet gasket and inner cap.Because rubber sheet gasket and inner cap are thicker, in piercing process, rubber sheet gasket and inner cap all easily fall 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 utility model provides a kind of when being used to make transfusion bag, and as long as the transfusion bag accessory is one welding sequence, form transfusion bag after contaminated probability low, with transfusion bag thin film energy good seal, puncture is difficult for falling bits when transfusion, is easy to puncture and the lower transfusion bag accessory of production cost.
The transfusion bag accessory of this utility model rhombus body seat band side-pull type infusion needle guide tube, comprise side-pull type infusion needle guide tube 1, connect 15 3 sections of body 7 and rhombus body seats successively preface become conjuncted structure, side-pull type infusion needle guide tube 1 port edge stretches out into welding ring 2, side-pull type infusion needle guide tube 1 be connected body 7 intersection outer walls stretch out become to hold the ring 12, it is characterized in that: side-pull type infusion needle guide tube 1 hollow is provided with seal dissepiment 3, is sealed with diaphragm seal 4 on the welding ring 2; Side-pull type infusion needle guide tube 1 sidewall that is right after diaphragm seal 4 is provided with easy-to-draw circle 5, connects pulling-on piece 6 on the easy-to-draw circle 5; The hollow of rhombus body seat 15 communicates with being connected body 7, and rhombus body seat 15 is that bottom surface 9 is rhombohedral rhombus cylinder.
Side-pull type infusion needle guide tube 1, connect that sky can communicate in 15 3 sections of body 7 and the rhombus body seats, sky is preferably circular in it, just side-pull type infusion needle guide tube 1 hollow is provided with the seal dissepiment 3 that transfusion needle easily pierces through, welding ring 2 is used for being connected with diaphragm seal 4, holds when ring 12 is used to infuse and holds steady side-pull type infusion needle guide tube 1 and be connected body 7.The position of easy-to-draw circle 5 is between seal dissepiment 3 and diaphragm seal 4, and other sidewall position of the wall ratio side-pull type infusion needle guide tube 1 of easy-to-draw circle 5 is thin, connects pulling-on piece 6 on the easy-to-draw circle 5.The bottom surface 9 of rhombus body seat 15 is a Pedicellus et Pericarpium Trapae shape; The solder side of two sides 10 for being used for being connected of rhombus body seat 15 with transfusion bag.In order to make rhombus body seat 15 better, thin slice 8 can be set at the two ends of two sides 10 with the welding effect of transfusion bag thin film.
Side-pull type infusion needle guide tube 1 internal diameter is less than or equal to and connects body 7 internal diameters.
Easy-to-draw circle 5 is that the annular ring between the line of two substantially parallel depressions is gone up in the side-pull type infusion needle guide tube 1 wall outside, and wall thickness is less than 3/4 of side-pull type infusion needle guide tube 1 wall thickness.
Attractive in appearance after pulling off easy-to-draw circle 5 for convenience and pulling off easy-to-draw circle 5, easy-to-draw circle 5 made the annular ring between the line of the side-pull type infusion needle guide tube 1 wall outside going up two substantially parallel depressions, its cup depth be approximately side-pull type infusion needle guide tube 1 pipe thickness 4/5～2/5.
3 one-tenth shallow " V " shapes of seal dissepiment, the concave surface of " V " shape are in the face of diaphragm seal 4.As 3 one-tenth shallow " V " shapes of seal dissepiment, when passing seal dissepiment 3, transfusion resin pin just can find the middle part of seal dissepiment 3 accurately, can not stab side-pull type infusion needle guide tube 1 sidewall; Two sides 10 are for smooth flat or a plurality of depression lattice 11 are arranged, and when a plurality of depression lattice, each depression especially surface becomes a plane.
When being used to infuse, inserts side-pull type infusion needle guide tube 1 transfusion needle; Diaphragm seal 4 is used to keep the health of side-pull type infusion needle guide tube 1; Seal dissepiment 3 is used to seal the medicinal liquid in the transfusion bag; Easy-to-draw circle 5 and pulling-on piece 6 are formed easy-to-draw opening apparatus, make it can be easy to remove diaphragm seal 4, expose the interior sky of side-pull type infusion needle guide tube 1, insert for transfusion needle.
The rhombus body seat 15 two ends flakiness 8 that can extend respectively makes the sealing of rhombus body seat 15 two ends and transfusion bag film better.
The bottom surface 9 of rhombus body seat 15 described in the utility model is a rhombus, and its major axis is than the long 0.2-5.0mm of minor axis.
Advantage of the present utility model: rhombus body seat and infusion needle guide tube are combined as a whole, when using this utility model to make transfusion bag, can reduce by one side-pull type infusion needle guide tube and be connected the body welding sequence, reduced the contaminated probability of medicinal liquid after the composition transfusion bag; The puncture seal barrier film is difficult for falling bits when transfusion, is easy to puncture, and bits are easily fallen in existing rubber blanket puncture; This utility model production cost is lower.
