Abstract
The utility model relates to a circular connecting pipe transfusion bag accessory with a top-pull transfusion needle catheter. The circular connecting pipe transfusion bag accessory with the top-pull transfusion needle catheter comprises a structure integrating the top-pull transfusion needle catheter with a connecting pipe body, wherein the edge of a port of the top-pull transfusion needle catheter is extended outwards to form a welding ring, the outer wall of a junction between the top-pull transfusion needle catheter and the connecting pipe body is extended outwards to form a hand-held ring, the top-pull transfusion needle catheter is hollow and provided with a seal diaphragm, and the welding ring is sealed by a top-pull seal cover; and the top-pull seal cover comprises a concave cover body and a pull ring, the middle of the concave cover body is provided with an easily-pull sealing strip the periphery of which is provided with easily-pull indents, and the pull ring is connected on the external surface of the easily-pull sealing strip. The circular connecting pipe transfusion bag accessory with the top-pull transfusion needle catheter 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 push-pull-type infusion needle guide tube, comprise push-pull-type infusion needle guide tube 1 and the conjuncted structure that is connected 7 two sections of bodys, push-pull-type infusion needle guide tube 1 port edge stretches out into welding ring 2, push-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, push-pull-type infusion needle guide tube 1 hollow is provided with seal dissepiment 3, is sealed with push-pull-type seal cover 4 on the welding ring 2; Push-pull-type seal cover 4 comprises matrix lid 30 and draw ring 31, is easy-to-draw diaphragm seal 32 in the middle of the matrix lid 30, and easy-to-draw diaphragm seal 32 peripheries are provided with easy-to-draw impression, and draw ring 31 is connected on the outer surface of easy-to-draw diaphragm seal 32.
Push-pull-type infusion needle guide tube 1 be connected body 7 in skies can communicate, sky is preferably circular in it, just push-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 seal cover 4, holds when ring 12 is used to infuse and holds steady push-pull-type infusion needle guide tube 1 and be connected body 7.Push-pull-type seal cover 4 is used to keep the health of push-pull-type infusion needle guide tube 1, easy-to-draw diaphragm seal 32 surfaces of push-pull-type seal cover 4 are connected with draw ring 31, when the easy-to-draw impression of easy-to-draw diaphragm seal 32 peripheries makes pulling draw ring 31, be easy to remove easy-to-draw diaphragm seal 32, the interior sky that exposes push-pull-type infusion needle guide tube 1 inserts for transfusion needle.
Push-pull-type infusion needle guide tube 1 internal diameter is less than or equal to and connects body 7 internal diameters.
When being used to infuse, inserts push-pull-type infusion needle guide tube 1 transfusion needle; Seal dissepiment 3 is used to seal the medicinal liquid in the transfusion bag; Push-pull-type seal cover 4 is used to keep the health of push-pull-type infusion needle guide tube 1, and is easy to remove easy-to-draw diaphragm seal 32, exposes the interior sky of push-pull-type infusion needle guide tube 1, inserts for transfusion needle.
Connecting body 7 has two effects, and one is that sky communicates as infusion channel with push-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.
Advantage of the present utility model: with the push-pull-type infusion needle guide tube be connected the integral body that body is made as once-forming, when using this utility model to make transfusion bag, can reduce one push-pull-type infusion needle guide tube and the welding sequence that is connected body, 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.
