Abstract
The utility model relates to a monotube gap bed monolocular infusion bag which belongs to a medical infusion bag. The monotube gap bed monolocular infusion bag comprises a bag body with solidly sealed periphery and a perfusion tube, and is characterized in that one side of the bag body is connected with a softer plastic film tube body seat which is provided with a perfusion hole, and one end of the perfusion tube is connected with the periphery of the perfusion hole; the mid-hollow of the perfusion tube is provided with a sealed septum, and a discharge hole of the perfusion tube is provided with a sealed cover. The monotube gap bed monolocular infusion bag has the advantages that a transitional connection of hard and soft materials is carried out to prevent the soft material of the connected part of the hard and soft materials from being bent and damaged, especially the thick part in the center of the plastic film tube body seat is connected with the hard material perfusion tube, and the thin part of the periphery is connected with a soft coating of the infusion bag, thereby realizing the optimum transitional connection of the hard material perfusion tube and the soft coating of the infusion 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, cause the connecting portion of tube for transfusion and bag in manufacturing process, to 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 non-damageable transfusion bag of transfusion bag connecting portion of making.
Design of the present utility model is: one side establish the plastic sheet of a kind of hardness between tube for transfusion and bag as the body seat, in addition three limit hot sealings at the transfusion bag.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:
This single tube and saddle type transfusion bag, the bag 21 and the tube for transfusion 2 that comprise the sealing of edge property, it is characterized in that: one side bag 21 be connected with softer plastic film body seat 1, softer plastic film body seat 1 is provided with infusion hole, one end of tube for transfusion 2 is connected with the infusion hole edge, and plastic film body seat 1 is communicated with tube for transfusion 2; The hollow of tube for transfusion 2 is provided with seal dissepiment 5, seal dissepiment 5 is suitably thick, when promptly the people pushes liquid in the transfusion bag, and the fluid pressure packing film 5 of decoding that can not rise, and transfusion needle can easier puncture seal dissepiment 5 when using, and makes transfusion needle can contact liquid in the transfusion bag; The discharging opening 8 of tube for transfusion 2 is provided with seal cover 9, and seal cover 9 usefulness rubber, plastic or other material are made.Film body seat 1 and tube for transfusion 2 constitute the transfusion bag accessory of single tube and saddle type body seat.
The effect of plastic film body seat 1 is harder tube for transfusion 2 cambic with very soft transfusion bag are 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 1 transition, plastic film body seat 1 is made thick middle and hard, thin edge and soft structure.Plastic film body seat 1 is a sheet pipe jointing part 6 with tube for transfusion 2 connecting portions, and plastic film body seat 1 is a sheet film connecting portion 7 with bag mantle connecting portion, and the thickness of sheet pipe jointing part 6 is greater than the thickness of sheet film connecting portion 7.
Plastic film body seat 1 is square, rectangle, circle, oval-shaped a certain, also can be irregular geometry.Plastic film body seat 1 can be direct injection mo(u)lding with being connected of tube for transfusion 2, also can be welding, bonding etc.It can be welding, bonding etc. that plastic film body seat 1 is connected with the mantle of transfusion bag.
Plastic film body seat 1 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 1 is connected with the lateral surface of transfusion bag, on the face that plastic film body seat 1 and tube for transfusion 2 main part phase-splittings are faced, can be provided with shallow anti-skidding depression 4.These shallow anti-skidding depressions 4 are used for holding steady transfusion bag when tube for transfusion 2 inserts transfusion needle.The character pattern depression that shallow anti-skidding depression 4 can be relevant trade mark, nomenclature of drug, usage, consumption etc.
Plastic film body seat 1 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 body seat 1.
The copolymer of material available polyethylene, polypropylene, ethylene and the propylene of plastic film body seat 1, tube for transfusion 2, 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 1 is made thick position, center and is connected with the tube for transfusion 2 of hard material, and the position of thin edge is connected with the bag of transfusion bag 1 mantle, has realized that the tube for transfusion 2 of hard material is connected with the transition of mantle the best of bag 1.
