Extremely shown in Figure 3 like Fig. 1; This utility model fusiformis body seat formula transfusion bag accessory; Comprise drawing and cover 4, infusion needle guide tube 1, connect body 7 and fusiformis body seat 15; Connection is provided with and connects body 7 on the fusiformis body seat 15, connects to be communicated with on the body 7 to be provided with infusion needle guide tube 1, and the end of infusion needle guide tube 1 is provided with and is used for drawing of its port sealing covered 4.Wherein, connecting body 7 is one-time formed conjuncted structures with fusiformis body seat 15.
The transitional link that the thickness aspect of fusiformis body seat 15 is connected with hard, soft two kinds of materials of thin and soft transfusion bag thin film as thick and hard connection body 7.Fusiformis body seat 15 has the diffusing pulling force of the joint face of increasing integration and prevents that damage and hard, the soft two kinds of materials of transition from preventing these two kinds of effects of bending damage.
In order to make fusiformis body seat 15 better with the welding effect of transfusion bag thin film, the thickness of side 10 is thinner than the thickness of fusiformis bottom surface 5.The elastic reaction of the fusiformis body seat 15 of this thick middle thin edge has solved hard connection body 7 and softish transfusion bag thin film in the flimsy problem of connecting portion.
Simultaneously, better in order to make fusiformis body seat 15 with the welding effect of transfusion bag thin film, at the two ends of 15 two sides 10 of fusiformis body seat thin slice 8 is set all.Thin slice 8 can also be further fixing with the transfusion bag welding.15 two sides 10 of fusiformis body seat can be smooth flat; Several depression lattice 11 perhaps are set on side 10; When a plurality of depression lattice, each depression especially surface becomes a plane, and the effect that depression lattice 11 are set also is in order to improve the welding effect of fusiformis body seat 15 and transfusion bag thin film.
7 and the infusion needle guide tube 1 that connect body are for being separately made; The 7 port edges that connect body stretch out into connection body welding ring 13; Infusion needle guide tube 1 lower port edge stretches out into infusion needle guide tube welding ring 12; Connect body 7 and be tightly connected each other through the sealing welding of two welding ring, connect body welding ring 13 and hold ring with the 12 sealing welding thermal synthesis of infusion needle guide tube welding ring with infusion needle guide tube 1.The hollow cross-section of infusion needle guide tube 1 is provided with seal dissepiment 3, and seal dissepiment 3 is a v-shaped structure, and thickness is 0.5mm, and the v-shaped structure opening direction is for to cover 4 direction towards drawing.Infusion needle guide tube 1 port edge stretches out into lid welding ring 2, and heat seal is tightly connected to draw and covers 4 on the lid welding ring 2.
Draw and cover 4 and comprise matrix lid 30, draw ring 31 and thin slice 32,30 seal welds of matrix lid are connected on the lid welding ring 2.Thin slices 32 for being tightly connected in the middle of the matrix lid 30 with it, thin slice 32 peripheries are provided with easy-to-draw impression, draw ring 31 be connected thin slice 32 above.Pull draw ring 31 during transfusion,,, just can pull off thin slice 32 very easily so pull draw ring 31 again because of thin slice 32 peripheries are provided with easy-to-draw impression because draw ring 31 links together with thin slice 32.
The advantage of this utility model: water can not infiltrate fully when sterilization, can guarantee that the seal dissepiment outer surface is in aseptic condition all the time, before container takes out medicinal liquid, need not the outer surface of seal dissepiment is carried out disinfection; The existence of no pad, the risk that the pad bits exist when having stopped puncture, and can easily puncture; The fusiformis hollow of fusiformis body seat connects body seat hollow cross-section, the mobile seriality of medicinal liquid when having guaranteed transfusion because of cross section is far longer than; Welding position when this structure of fusiformis body seat can reduce transfusion production, the transfusion bag accessory needs only one welding sequence, and production cost is low; The existence of seal dissepiment greatly reduces the probability of medicinal liquid seepage, form transfusion bag after contaminated probability reduce greatly; Fusiformis body seat and transfusion bag thin film can excellent sealings.
With the conjuncted structure of polypropylene granules single injection-molded connection body 7 and fusiformis body seat 15, the port both sides that connect body 7 stretch out and become to connect needle tubing welding ring 13; With polypropylene granules difference injection mo(u)lding lid 4 and infusion needle guide tube 1.The port both sides of infusion needle guide tube 1 stretch out and become to take in succession body welding ring 12; Again infusion needle guide tube is taken over body welding ring 12 in succession and is connected body and connects 13 hot sealings of needle tubing welding ring.
The concrete structure and the size of each several part are following:
Infusion needle guide tube 1 stretches out and becomes to take in succession body welding ring 12, and welding ring 12 internal diameters are 5.0mm, and external diameter is 12.0mm, and width is 3.5 mm, and thickness is 2.0mm; Seal dissepiment 3 is arranged in the draw-ring type infusion needle guide tube, 3 one-tenth shallow " V " shapes of seal dissepiment, concave surface facing draw-ring type seal cover 4, its thickness are 0.5 mm;
Connecting body 7 length is 15.0mm, and internal diameter is 10.0mm, and wall thickness is 1.0mm.The port both sides that connect body 7 stretch out and become to connect infusion needle guide tube welding ring 13, and connecing infusion needle guide tube welding ring 13 internal diameters is 10.0mm, and external diameter is 16.0mm, and width is 3.0mm, and thickness is 2.0mm.
The hollow of fusiformis body seat 15 is that its bottom surface 9 is a fusiformis greater than the fusiformis that connects body 7 internal diameters, and the major axis of fusiformis is 35.0mm, and minor axis is 12.0mm; Two side 10 width of fusiformis body seat 15 are 10.0mm.
