Abstract
The utility model discloses a disposable polyurethane precise filter infusion set. The disposable polyurethane precise filter infusion set comprises a puncture device, a drip chamber, an infusion catheter, an adjuster, a filter, a venous duct and a vein needle, wherein the tail end of the puncture device is communicated with a liquid inlet end of the drip chamber, a liquid outlet end of the drip chamber is communicated with a liquid inlet of the infusion catheter, a liquid outlet of the infusion catheter is communicated with a liquid inlet end of the filter, a liquid outlet end of the filter is communicated with a liquid inlet of the venous duct, a liquid outlet of the venous duct is communicated with the vein needle, the adjuster is connected in the infusion catheter, the drip chamber, the infusion catheter and the vein duct are respectively of a double-layer structure and composed of an inner layer and an outer layer, the inner layers are made of a polyurethane material, and the outer layers are made of a PVC material. According to the disposable polyurethane precise filter infusion set, the harm to the human body caused when plasticizer is transferred and dissolved out from a catheter in the using process is avoided, and absorption of medicine liquid in the infusion process can be reduced.
Description
Technical field
This utility model relates to a kind of disposable use polyurethane precision filter infusion set, belongs to medical instruments field.
Background technology
At present, the main material that China's disposable infusion set uses is polrvinyl chloride (PVC) transfusion device of dioctyl phthalate (DEHP) plasticising, the deficiency of PVC transfusion device in transfusion is mainly manifested in aspect two: the migration of plasticizer DEHP and stripping in the one, PVC, threaten to health; The 2nd, some medicines can be adsorbed by PVC, lessen the curative effect.Many authoritys' international research tissue is studied the toxicity of DEHP, finds that it can produce multiple harmful effect to body, as reproduction and development toxicity, mutagenicity and carcinogenecity, general toxicity, endocrine and induced tumor generation etc.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, a kind of disposable use polyurethane precision filter infusion set is provided, it not only can avoid the transfusion device harm that in use plasticizer moves from conduit and stripping produces human body, and can reduce the adsorption of infusion process herb liquid.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of disposable use polyurethane precision filter infusion set, comprise perforator, dropping funnel, transfusion catheter, actuator, filter, venous duct and intravenous needle, the end of perforator is connected with the liquid feeding end of dropping funnel, the liquid outlet of dropping funnel is connected with the inlet of transfusion catheter, the liquid outlet of transfusion catheter is connected with the liquid feeding end of filter, the liquid outlet of filter is connected with the inlet of venous duct, the liquid outlet of venous duct is connected with intravenous needle, actuator is connected in transfusion catheter, dropping funnel, transfusion catheter and venous duct are double-decker, and by internal layer and outer composition, internal layer is made up of polyurethane material, skin is made up of PVC material.
Adopt after technique scheme, the internal layer of dropping funnel, transfusion catheter and the venous duct directly contacting with medicinal liquid is made up of polyurethane material, internal layer prepared by this material does not contain plasticizer, and there is low absorbability, can reduce migration of plasticizer and stripping, reduce the adsorption to medicine in infusion process, therefore product is safely and efficiently simultaneously.
Brief description of the drawings
Fig. 1 is the connection diagram of disposable use polyurethane precision filter infusion set of the present utility model;
Fig. 2 is the cross-sectional view of dropping funnel or transfusion catheter or venous duct.
Detailed description of the invention
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail below.
As Fig. 1, shown in 2, a kind of disposable use polyurethane precision filter infusion set, comprise perforator 1, dropping funnel 2, transfusion catheter 3, actuator 4, filter 5, venous duct 6 and intravenous needle 7, the end of perforator 1 is connected with the liquid feeding end of dropping funnel 2, the liquid outlet of dropping funnel 2 is connected with the inlet of transfusion catheter 3, the liquid outlet of transfusion catheter 3 is connected with the liquid feeding end of filter 5, the liquid outlet of filter 5 is connected with the inlet of venous duct 6, the liquid outlet of venous duct 6 is connected with intravenous needle 7, actuator 4 is connected in transfusion catheter 3, dropping funnel 2, transfusion catheter 3 and venous duct 6 are double-decker, and by internal layer a and outer b composition, internal layer a is made up of polyurethane material, outer b is made up of PVC material.
Operation principle of the present utility model is as follows:
The internal layer of dropping funnel 2, transfusion catheter 3 and the venous duct 6 directly contacting with medicinal liquid is made up of polyurethane material, internal layer prepared by this material does not contain plasticizer, and there is low absorbability, can reduce migration of plasticizer and stripping, reduce the adsorption to medicine in infusion process, therefore product is safely and efficiently simultaneously.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that this utility model is solved further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
