Description
Technical field
This utility model belongs to the medical infusion bags accessory.
Background technology
The tube for transfusion of medical infusion bags, pouring pipe are main accessories, because it is harder that the material of tube for transfusion, pouring pipe requires, and the requirement of the material of the bag of transfusion bag is very soft, cause the connecting portion of harder tube for transfusion, pouring pipe and 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, pouring pipe are circular under normal conditions, make the connecting portion of tube for transfusion, pouring pipe 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, pouring pipe and bag, just the connecting portion at tube for transfusion, pouring pipe 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 the non-damageable transfusion bag accessory of a kind of tube for transfusion, pouring pipe and bag material connecting portion.
Design of the present utility model is: make the body seat with the plastics of a kind of hardness between tube for transfusion, pouring pipe and bag, tube for transfusion, pouring pipe and body seat three are integrated becomes the transfusion bag accessory.Because of the hardness of body seat and tube for transfusion, pouring pipe and bag is close, thereby make the connecting portion of body seat and tube for transfusion, pouring pipe and bag not fragile.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:
The transfusion bag accessory of two-tube and saddle type body seat, comprise softer plastic film shape body seat, tube for transfusion, a pouring pipe, it is characterized in that: plastic film shape body seat is provided with infusion hole and fill hole, one 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.In the same side of tube for transfusion, an end of pouring pipe is fixedlyed connected with the fill bore edges, pouring pipe and fill hole mutually, pour into medicinal liquid after, with the charging aperture of welding or alternate manner sealing pouring pipe.
The effect of plastic film shape body seat is harder tube for transfusion, pouring pipe is cambic is connected with very soft transfusion bag, prevent from firmly directly to be connected with soft material very, 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 shape body seat transition, plastic film shape body seat is made thick middle and hard, thin edge and soft structure.Plastic film shape body seat and tube for transfusion and pouring pipe connecting portion are sheet shape pipe jointing part, and the edge of plastic film shape body seat is a sheet film connecting portion, and the thickness of sheet shape pipe jointing part is greater than the thickness of sheet film connecting portion.
Plastic film shape body seat is square, rectangle, circle, oval-shaped a certain, also can be irregular geometry.Plastic film shape body seat can be a single injection-molded with being connected of tube for transfusion and pouring pipe, also can be welding, bonding etc.It can be welding, bonding etc. that plastic film shape body seat is connected with the mantle of transfusion bag.
The Kongxiang is logical in pouring pipe and the medicated bag, and the charging aperture of pouring pipe is an opening.After in medicated bag, being filled into the medicinal liquid of regulation, with the charging aperture sealing of pouring pipe by pouring pipe.The sealing mode can be the permanent closure of heating welded closure or other form.
Plastic film shape 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 shape body seat is connected with the lateral surface of transfusion bag, on the face that plastic film shape body seat and tube for transfusion and the phase-splitting of pouring pipe 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 shape body seat edge forms a complete bag with after the bag film material of transfusion bag is connected, and two facial films of bag will pull into the shape of a saddle to plastic film shape body seat.
Copolymer, polyethylene and the polyacrylic mixture of plastic film shape body seat, tube for transfusion, pouring pipe three's material available polyethylene, polypropylene, ethylene and propylene, 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 shape body seat is made thick position, center and is connected with pouring pipe with the tube for transfusion of hard material, the position of thin edge is connected with the mantle of transfusion medicated bag, has realized that the transition with mantle the best of transfusion medicated bag is connected with pouring pipe for the tube for transfusion of hard material.The special pouring pipe that is provided with is convenient to liquid drug, sealed feed inlet after being filled into medicinal liquid.As charging aperture acupuncture or other vestige are arranged, show that then medicine changes in the bag chamber that communicates with this pouring pipe.
