Abstract
The utility model relates to a disposable light-tight dropping funnel for a transfusion system, belonging to a medical instrument. A liquid inlet is arranged at the top of a funnel body, a liquid outlet is arranged at the bottom thereof, characterized in that the funnel body is in an integrated double-layer composite structure, the internal layer is a PVC layer, the external layer is a light-tight PVC layer, the internal layer and the external layer are in one-shot forming by a double-layer co-extruder. The structure is simple and reasonable, the pollution of the dissolving-out photophobic pharmaceutical on the liquid medicine is fundamentally avoided, thus the disposable light-tight dropping funnel is safe and reliable.
Description
Technical field
This utility model relates to improved disposable use light proofing infusion apparatus dropping funnel, belongs to medical apparatus and instruments.
Background technology
At present, the disposable use light proofing infusion apparatus of clinical use in order to reach the requirement of lucifuge, all adds the lucifuge agent in the transfusion device raw material, and the mode that has even adopt the interpolation common dye reaches the purpose of lucifuge.Therefore, in infusion process, the lucifuge agent in the transfusion device material can be dissolved in the medicinal liquid inevitably to a certain extent, has influence on the quality of infusion medicinal liquid, and input people cognition causes very serious consequence and harm.
The utility model content
The purpose of this utility model is to provide a kind of improved disposable use light proofing infusion apparatus dropping funnel, has fundamentally avoided the pollution of lucifuge agent to medicinal liquid, and is safe and reliable.
Disposable use light proofing infusion apparatus dropping funnel described in the utility model, inlet is arranged at the top of bucket body, and liquid outlet is arranged at the bottom, and its bucket body is the two-layer composite of integral type, and internal layer is the PVC layer, skin is a lucifuge PVC layer.
Internal layer, skin can pass through the one-shot forming of double-layer coextrusion machine double-layer coextrusion, and be effective, dependable performance.
PVC is the general infusion set organic material, also claims polrvinyl chloride; Lucifuge PVC makes by add the lucifuge agent in PVC, and the lucifuge agent has female element of commercially available color and titanium dioxide etc., and the weight addition is 0.1-20%.
Lucifuge PVC layer is coated on the outer surface of disposable use light proofing infusion apparatus with dropping funnel, does not contact medicinal liquid, can not pollute medicinal liquid, only plays the lucifuge protective action, therefore can have multiple material to select, and globality is strong, and is effective.When lucifuge PVC layer was selected, the light transmittance of the light in its lucifuge performance selection 290-450nm wave-length coverage was not more than 35% and is advisable, and not only plays the lucifuge effect, is able to observe the purpose that has or not inspection situations such as bubble with drop weight again.
Also just because of the lucifuge protection has been arranged, internal layer need not to add the lucifuge agent again, has fundamentally avoided the influence of lucifuge agent to medicinal liquid, and is simple in structure, safe and reliable.
The disposable use light proofing infusion apparatus of this utility model dropping funnel, simple and reasonable, fundamentally avoided the pollution of lucifuge agent stripping to medicinal liquid, safe and reliable.
Description of drawings
Fig. 1, this utility model one example structure sketch map.
Among the figure: 1, internal layer 2, skin.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
As shown in the figure, disposable use light proofing infusion apparatus dropping funnel described in the utility model, inlet is arranged at the top of bucket body, liquid outlet is arranged at the bottom, bucket body is the two-layer composite of integral type, internal layer 1 is the PVC layer, and outer 2 is lucifuge PVC layer, internal layer, outer by the one-shot forming of double-layer coextrusion machine double-layer coextrusion.
