Abstract
The utility model relates to a face-to-face single tube single-chamber transfusion bag with two tube body seats, which belongs to a medical transfusion bag. The transfusion bag comprises a bag body with peripheral edges fixed and sealed permanently, a softer boat-shaped tube body seat with internally-hollow boat type structure and a transfusion tube, wherein, a transfusion hole is arranged at the boat-shaped bottom part of the softer boat-shaped tube body seat, and one end of the transfusion tube is fixedly connected with the edge of the transfusion hole; a seal diaphragm is arranged in the hollow of the transfusion tube; a sealed cover is arranged at the discharge hole of the transfusion tube. The bag body is made of a non-PVC multilayer co-extrusion member, three edges of the rectangular bag body are sealed in a hot press way, one open edge is sealed with the tube body seat with the internally-hollow boat type structure in a hot press way. The transfusion bag has the advantage that hard material is transitionally connected with soft material, to prevent the soft material at the connecting part of the hard material and the soft material from being bended and damaged. Particularly, a thick part at the center of the boat-shaped tube body seat is connected with a hard transfusion tube, and the part on the thin edge is connected with the transfusion bag, to realize the optimal transitional connection of the hard transfusion tube and the soft member of the transfusion bag.
Description
Technical field
This utility model belongs to medical infusion bags.
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 the requirement of the material of the bag of transfusion bag is very soft, cause the harder tube for transfusion and the connecting portion of very soft bag to produce breakage, thereby the powder charge hydrorrhea is gone out and external microbe pollutes a bag inner liquid medicine because of bending.And tube for transfusion is circular under normal conditions, make the connecting portion of tube for transfusion and bag in manufacturing process, 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 the connecting portion at tube for transfusion and bag is provided with the body seat of being made by relatively hard materials or claims Connection Block, and the width of body seat is less than the width of bag fillet.This structure such as Chinese patent 200520052881.8,200620050623.0,200620050316.2,200420036219.9.But the connecting portion of this body seat or title Connection Block and bag still produces breakage because of bending easily.
Summary of the invention
The purpose of this utility model provides a kind of tube for transfusion and non-damageable transfusion bag of transfusion bag connecting portion of making.
Design of the present utility model is: a minor face of transfusion bag establish a kind of in the body seat of clean ship formula structure, another minor face is established pouring pipe, two long limit hot sealings.Body seat contour structures is interior clean ship formula structure, and body seat hardness is between tube for transfusion and bag material.The harder lower portion of harder tube for transfusion and interior clean ship formula structure is communicated with, and softer " the ship limit " of the boat form structure of interior sky is used for being connected with the flexible plastic bag of transfusion bag.Because " ship limit " is softer, and the surface is level and smooth substantially, the connecting portion of bag is difficult for bending, can prevent that two kinds of material connecting portions of soft or hard from damaging the situation of soft material because of bending.
Structure of the present utility model is: the bag that comprises the permanent fixing seal in edge, it is characterized in that: one side the body seat, the tube for transfusion that are connected with softer interior clean ship formula structure of bag, the bag another side relative with the body seat is connected with pouring pipe, and pouring pipe is connected with bag with solid ship shape body seat.The ship shape bottom of softer ship shape body seat is provided with infusion hole, and an end of tube for transfusion is fixedlyed connected with the infusion hole edge, and the interior sky of ship shape body seat is communicated with tube for transfusion; Hollow at tube for transfusion is provided with seal dissepiment, seal dissepiment is suitably thick, when promptly the people pushes liquid in the transfusion bag, and the fluid pressure packing film of decoding that can not rise, and transfusion needle can easier puncture seal dissepiment when using, and makes transfusion needle can contact liquid in the transfusion bag; The discharging opening of tube for transfusion is provided with seal cover, and seal cover is made with rubber, plastic or other material.Ship shape body seat and tube for transfusion constitute the transfusion bag accessory of single tube and interior clean ship formula body seat.
The effect of interior clean ship shape body seat is cambic with the very soft transfusion bag bag of harder tube for transfusion is connected, and prevents from directly to be connected with soft material very firmly, cause produce and use in, incite somebody to action the connecting portion damage of very soft transfusion bag because of bending.Be to increase the hard soft two kinds of material linkage functions of ship shape body seat transition, ship shape body seat is made thick middle and hard, thin edge and soft structure.Ship shape body seat and tube for transfusion connecting portion are the ship pipe jointing part, and the edge of ship shape body seat is a ship film connecting portion, and the thickness of ship pipe jointing part is greater than the thickness of ship film connecting portion.
Interior clean ship shape body seat can be a single injection-molded with being connected of tube for transfusion, also can be hot pressing welding, bonding etc., the mantle of ship shape body seat and transfusion bag be connected can be hot pressing weld, bonding etc.
Can be provided with shallow anti-skidding depression on the outer surface of ship shape body seat.These shallow anti-skidding depressions are used for holding steady transfusion bag when tube for transfusion inserts transfusion needle.The character pattern depression that shallow anti-skidding depression can be relevant trade mark, nomenclature of drug, usage, consumption etc.
Ship shape body seat and pouring pipe form a complete transfusion bag with after the bag of transfusion bag is connected.Pour into hot sealing pouring pipe behind the medicinal liquid from open pouring pipe.
The charging aperture of pouring pipe is open state or sealing state.
Copolymer, polyethylene and the polyacrylic mixture of material available polyethylene, polypropylene, ethylene and the propylene of single tube and interior clean ship formula accessory and solid ship shape body seat pouring pipe, modified poly ethylene, modified polypropene etc.
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.Particularly ship shape body seat is made thick position, center and is connected with the tube for transfusion of hard material, and the position of thin edge is connected with the mantle of transfusion medicated bag, has realized that the tube for transfusion of hard material is connected with the transition of mantle the best of the medicated bag of infusing; The special pouring pipe that is provided with is convenient to liquid drug, be filled into medicinal liquid in bag after, with the charging aperture sealing of pouring pipe.As charging aperture acupuncture or other vestige are arranged, show that then medicine changes in the bag that communicates with this pouring pipe.
