Abstract
The utility model relates to a circular connecting pipe transfusion bag accessory with a side-pull transfusion needle catheter, belonging to a pipeline sealing device and a pipeline which can be smoothly connected with a transfusion bag diaphragm to take in or discharge liquid. The circular connecting pipe transfusion bag accessory with the side-pull transfusion needle catheter comprises a structure integrating the side-pull transfusion needle catheter with a connecting pipe body, wherein the edge of a port of the side-pull transfusion needle catheter is extended outwards to form a welding ring, and the outer wall of a junction between the side-pull transfusion needle catheter and the connecting pipe body is extended outwards to form a hand-held ring. The circular connecting pipe transfusion bag accessory with the side-pull transfusion needle catheter is characterized in that the side-pull transfusion needle catheter is hollow and provided with a seal diaphragm, and the welding ring is sealed by a sealing strip; and the side wall of the side-pull transfusion needle catheter, which is closely connected with the sealing strip, is provided with an easily-pull ring on which a pull strip is arranged. The transfusion bag accessory has the advantages that a seat for the pipe body and the transfusion needle catheter are connected into a whole, thereby reducing one welding procedure during transfusion preparation and reducing the pollution ratio of liquid medicines; scrapes are not easy to fall in a puncturing process, and the operation of puncture can be easily carried out; and the production cost is lower.
Description
Technical field
This utility model belongs to the medical infusion bags accessory.
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 the production transfusion bag.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, puncture is difficult for falling bits during transfusion, is easy to puncture and the lower transfusion bag accessory of production cost.
Structure of the present utility model is:
The circular transfusion bag accessory that connects pipe racks side-pull type infusion needle guide tube, comprise side-pull type infusion needle guide tube 1 and the conjoined structure that is connected 7 two sections of bodys, 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.
Side-pull type infusion needle guide tube 1 be connected body 7 in skies can communicate, 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.
Side-pull type infusion needle guide tube 1 internal diameter is less than or equal to and connects body 7 internal diameters.
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.
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.
Connecting body 7 has two effects, and one is that sky communicates as infusion channel with side-pull type infusion needle guide tube 1 in the end, and the 2nd, the lateral wall of the other end is used for being connected synthetic transfusion bag with the transfusion diaphragm seal, and the open section part that promptly connects body 7 is as circular connection tube.
Advantage of the present utility model: with the side-pull type infusion needle guide tube be connected the integral body that body is made as once-forming, can reduce one side-pull type infusion needle guide tube and the welding sequence that is connected body when using this utility model production transfusion bag, reduce the contaminated probability of medicinal liquid after the composition transfusion bag; In piercing process, be difficult for falling bits, be easy to puncture; And production cost is lower.
