At present there has been the medical material of the non-PVC that can replace PVC to comprise: polyethylene, ethylene-vinyl acetate polymer, polyurethane, TPO, polyethylene terephthalate etc., if but adopt above-mentioned material to make transfusion device flexible pipe, infusion unit titrimeter and transfusion device thereof, though safety, but cost is more expensive than PVC material, complex process, industrialization are difficult.
For the identical continuous tubular plastic spare in cross section, generally adopt plastic extruder water-cooled molding after mould is extruded, for double-deck or multiwalled above-mentioned working of plastics, then generally adopt the technology of coextrusion mold.
The utility model content
For transfusion device flexible pipe, infusion unit titrimeter and the transfusion device thereof that can either overcome the existing plastifying medical polyvinyl of DEHP to the toxic harm of human body or drug effect there is the deficiency of impairment, can reduce production cost again, technical problem to be solved in the utility model provides a kind of safer transfusion device flexible pipe, infusion unit titrimeter and transfusion device thereof that has cost advantage again simultaneously as far as possible.
Transfusion device flexible pipe of the present utility model comprises tube wall, and described tube wall is made of two-layer at least, and innermost layer wherein is adjacent layer and adopts coextrusion mold, and innermost layer is the safeguard protection layer.
Described tube wall is by innermost layer and outer the composition, and its outer polrvinyl chloride that adopts is made.
Infusion unit titrimeter of the present utility model comprises the tubular container of both ends open, and the tube wall of described tubular container is made of two-layer at least, and innermost layer wherein is adjacent layer and adopts a coextrusion mold, and innermost layer is the safeguard protection layer.
The tube wall of described tubular container is by innermost layer and outer the composition, and its outer polrvinyl chloride that adopts is made.
Transfusion device of the present utility model comprises bottle plug puncture unit and venoclysis needle, also comprises above-mentioned transfusion device flexible pipe and above-mentioned infusion unit titrimeter, and described bottle plug puncture unit, infusion unit titrimeter and venoclysis needle are hose connection by described transfusion device.
In above-mentioned the transfusion device flexible pipe and infusion unit titrimeter; as the innermost layer of safeguard protection layer, can adopt in " polyethylene, ethylene-vinyl acetate polymer, polyurethane, TPO, polyethylene terephthalate, with the polrvinyl chloride of other elasticizer plasticizing except that DEHP " any or different materials to make.
The beneficial effects of the utility model are: the transfusion device that adopts above-mentioned bilayer or multilayer materials, compare with the medical polymer material or the plastifying pvc material transfusion device of the non-DEHP of single employing of single employing non-PVC, can either avoid harm of infusion process toxic or drug effect impairment, has cost advantage again simultaneously, cost performance is higher, and processing technique is simple.
