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 tube for transfusion of medical infusion bags is main accessory.Because it is harder that the material of tube for transfusion requires, and that the material of transfusion bag requires is softer, causes the harder tube for transfusion and the connecting portion of very soft bag to produce breakage because of bending.Thereby the intravital medicinal liquid of bag is overflowed with external microbe pollute the bag inner liquid medicine.And tube for transfusion is circular under normal conditions, cause the connecting portion of tube for transfusion and bag in manufacturing process, to be difficult to sealing, so people are provided with the tube for transfusion wing that is beneficial to sealing in manufacturing process at the connecting portion of tube for transfusion and bag, just be provided with the body seat of making by hard material or claim the disjunctor seat at tube for transfusion and bag connecting portion, the width of body seat is less than the width of bag fillet, but the connecting portion of this body seat or title disjunctor seat and bag still produces breakage because of bending.
The utility model content
The purpose of this utility model provides a kind of layback tube for transfusion and the non-damageable transfusion bag accessory of bag connecting portion.
Structure of the present utility model is:
The transfusion bag accessory of interior clean ship formula body seat band layback infusion needle guide tube, comprise layback infusion needle guide tube 1, connect 9 three sections of body 7 and interior clean ship formula body seats successively preface become conjuncted structure, layback infusion needle guide tube 1 port edge stretches out into welding ring 2, layback 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: layback infusion needle guide tube 1 hollow is provided with seal dissepiment 3, is sealed with diaphragm seal 4 on the welding ring 2; Layback 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 interior clean ship formula body seat 9 communicates with being connected body 7, and its connecting portion is ship pipe jointing part position 10.The ship shape edge sidewall of interior clean ship formula body seat 9 is ship film welding position 11.
Layback infusion needle guide tube 1, connect that sky can communicate in 9 three sections of body 7 and the interior clean ship formula body seats, sky is preferably circular in it, just layback 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 layback 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 layback 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 hollow of interior clean ship formula body seat 9 communicates with being connected body 7, and its connecting portion is ship pipe jointing part position 10.The ship shape edge sidewall of interior clean ship formula body seat 9 is ship film welding position 11, and the thickness of ship pipe jointing part position 10 is greater than the thickness of ship film welding position 11.
Layback 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 layback infusion needle guide tube 1 wall outside, and wall thickness is less than 3/4 of layback 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 layback infusion needle guide tube 1 wall outside going up two substantially parallel depressions, its cup depth be approximately layback 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 layback infusion needle guide tube 1 sidewall.
When being used to infuse, inserts layback infusion needle guide tube 1 transfusion needle; Diaphragm seal 4 is used to keep the health of layback 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 layback infusion needle guide tube 1, insert for transfusion needle.
The ship pipe jointing part position 10 of interior clean ship formula body seat 9 be connected body 7 hollows more firmly and connect, softer ship film welding position 11 welds with the co-extrusion film heat seal of transfusion bag, be optimum transfer and connect, thereby prevented that the bag inner liquid medicine from overflowing and an external microbe pollution bag inner liquid medicine.
Advantage of the present utility model: make hard soft two kinds of materials carry out transitional the connection, prevent that the soft material of hard soft two kinds of material connecting portions from being bent damage.Connection body and harder tube for transfusion heat seal welding that particularly interior clean ship formula body seat center is thicker, the ship film welding position of thin edge and the mantle heat seal of transfusion bag welding have realized that the tube for transfusion of hard material is connected with the transition of mantle the best of transfusion bag.
