A kind of infusion pipelineTechnical field
The utility model is related to medical instruments field, more particularly to a kind of infusion pipeline.
Background technology
Liquid in container is discharged into transfusion by traditional infusion device provided with exposed body-free transfusion puncture needle to puncture into infusion vesselDevice, nursing staff needs hand-held exposed body-free transfusion puncture needle operation when changing transfusion, easily accidentally injures.
Body-free transfusion puncture needle is smooth because of surface, and adhesive force is low, when inserting infusion vessel, such as because attached on transfusion device and transfusion devicePart is excessive, overweight, easily slips, and forms medical hidden danger；Meanwhile, because puncture needle needs part to be exposed in outside air, easilyIt is contaminated, when contaminated puncture needle punctures into next bottle of transfusion again, decoction can be caused contaminated.
Existing body-free transfusion puncture needle is worn substantially provided with hollow pipeline with facilitating decoction water conservancy diversion, but being provided with the transfusion of hollow pipelineThe production cost of pricker is higher, and required puncture force is larger, it is often more important that it can bring more puncture chips.
Nursing staff need to come back when patrolling transfusion condition and observe infusion vessel situation, also need to look squarely observation dropping funnel situation,Increase nursing staff's workload.
The flow set formula infusion regulator of existing modular structure up and down is because of two sealing surfaces above and below being related to, in systemMake very difficult during sealing gasket, excessively soft, regulation resistance is very big；It is really up to the mark and leak or infiltration occurs.
Have and speed governing groove and liquid are flowed into groove or liquid spout is arranged on firm banking, because it can be by sealing surface by doubleFace is optimized for one side, hence it is evident that the manufacture craft of reduction sealing gasket, but design is needed when making firm banking mould same flatThe groove of two same centers of circle and high processing request is provided with face, causes difficulty of processing to significantly increase.
The complexity of processing technology and the increase of difficulty, cause the costs such as mould, injection to increase, so as to cause product cost to occupyIt is high not under, it is difficult to popularization and application.
