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 claiming 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 this body seat (or claiming Connection Block) still produces breakage because of bending easily with the connecting portion of bag.
Summary of the invention
The purpose of this utility model provides a kind of tube for transfusion and the non-damageable transfusion bag of bag material connecting portion.
Design of the present utility model is: establish single tube and straddle transfusion bag accessory on the liquid splitting of liquid splitting that has a weak weldering spacer bar to be separated into and the synthetic bag of solid splitting, prevent that tube for transfusion hard material and transfusion bag soft material connecting portion from being bent damage.Single tube and straddle transfusion bag accessory are made the body seat with the plastics of a kind of hardness between tube for transfusion and bag, and tube for transfusion and body seat are integrated becomes the transfusion bag accessory.Body seat contour structures is the sheet type structure, and body seat sheet material hardness is between tube for transfusion and bag material.Because the sheet material edge is softer, and the surface is level and smooth substantially, the connecting portion of sheet material and bag is difficult for bending to be damaged, and 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: two chambers bag of single tube and saddle type accessory and rhombus base powder filling pipe, the bag that comprises the edge fixing seal, establish weak weldering spacer bar in the middle of the bag, weak weldering spacer bar is separated into two splittings that do not communicate with bag, one of them is the liquid splitting, another is the solid splitting, is provided with the Obstruct membrane that is made of composite aluminium film at the lateral surface of solid splitting bag film.It is characterized in that: solid splitting afterbody is provided with the powder filling pipe, and the connecting portion profile of powder filling pipe and solid splitting is a rhombogen body seat; Liquid splitting and single tube and Ma An Shi Group close the edge fixing seal of transfusion bag accessory; Softer plastic film body seat is provided with infusion hole, and an end of tube for transfusion is fixedlyed connected with the infusion hole edge, and tube for transfusion communicates with infusion hole; 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 transfusion needle can contact the liquid in the transfusion bag; The discharging opening of tube for transfusion is provided with seal cover, and seal cover is made with materials such as plastics, rubber.
The effect of plastic film body seat is cambic with the very soft transfusion 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 plastic film body seat transition, plastic film body seat is made thick middle and hard, thin edge and soft structure.Plastic film body seat and tube for transfusion connecting portion are the sheet pipe jointing part, and the edge of plastic film body seat is a sheet film connecting portion, and the thickness of sheet pipe jointing part is greater than the thickness of sheet film connecting portion.
Plastic film body seat is square, rectangle, circle, oval-shaped a certain, also can be irregular geometry.Plastic film body seat can be a single injection-molded with being connected of tube for transfusion, also can be welding, bonding etc.It can be welding, bonding etc. that plastic film body seat is connected with the mantle of transfusion bag.
Plastic film body seat can be connected with the medial surface of transfusion bag, also can be connected with the lateral surface of transfusion bag.
When plastic film body seat is connected with the lateral surface of transfusion bag, on the face that plastic film body seat and the phase-splitting of tube for transfusion main part are faced, can be provided with shallow anti-skidding depression.These shallow anti-skidding depressions are used for when tube for transfusion inserts transfusion needle, can be holding steady transfusion bag.The character pattern depression that shallow anti-skidding depression can be relevant trade mark, nomenclature of drug, usage, consumption etc.
Plastic film body seat, powder filling pipe and after the bag film material of transfusion bag is connected form a complete bag, and two facial films of bag will pull into the shape of a saddle to plastic film body seat.
The copolymer of plastic film body seat, tube for transfusion, powder filling pipe three's material available polyethylene, polypropylene, ethylene and propylene, polyethylene and polyacrylic mixture, 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 plastic film 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 powder filling pipe that is provided with is convenient to fill medicated powder, be filled into the sterile solid medicine in bag after, with the charging aperture sealing of powder filling pipe.As charging aperture acupuncture or other vestige are arranged, show that then medicine changes in the bag that communicates with this powder filling pipe.
