Abstract
The utility model discloses a disposable light-proof infusion apparatus which comprises a puncture device, a dripping hopper, a liquid medicine filter, a liquid flow rate adjustor and a joint which are sequentially connected together in series by infusion catheters; the disposable light-proof infusion apparatus is characterized in that the dripping hopper and the infusion catheters have structure with an internal layer and an external layer, wherein the external layer is made of light-proof black or brown polyvinyl chloride material, and the internal layer is made of transparent polyvinyl chloride material; and the liquid medicine filter comprises filtering films which are arranged at the upper and the lower layers, wherein the filtering film arranged at the upper layer is a precise filtering film, and the filtering film arranged at the lower layer is a support filtering film. The disposable light-proof infusion apparatus has light-proof function, has simple structure, is disposable, safe and reliable as well as convenient for operation, and has very positive effect for improving the clinical medical treatment efficiency, enhancing the treatment effect and further reducing the occurrence of medical negligence. The product can be widely applied to intravenous infusion needing light-proof medicine, and is also applicable to all intravenous infusion which does not need the light-proof medicine.
Description
One, technical field
This utility model belongs in a kind of medicine and hygiene fields the infusion set of using when carrying out venous transfusion to clinical patients, specifically relate in venous transfusion, have when needing lucifuge can safe medication disposable use light proofing infusion apparatus.
Two, background technology
Some medicine in the clinical treatment---for example sodium nitroprusside, nitroglycerin etc. need be infused under the lucifuge condition, could ensure patient's drug safety.At present, though seeing light proofing infusion apparatus is used in the clinical treatment, but the common light proofing infusion apparatus of this class all ubiquity such defective: transfusion catheter on the common light proofing infusion apparatus and dropping funnel all have only the lucifuge layer and the clear layer that medicinal liquid and lucifuge layer do not intercepted, cause medicinal liquid directly to contact with the lucifuge layer, also disengage because of the chemical substance of lucifuge layer, the chemical material generation chemical reaction of the just big chance of medicinal liquid and lucifuge layer causes medication dangerous and malpractice takes place easily.
Three, utility model content
The purpose of this utility model is that a kind of disposable use light proofing infusion apparatus will be provided, and solving the above-mentioned drawback of existing common light proofing infusion apparatus, thereby reaches the usefulness of safe infusion and safe medication.
The purpose of this utility model is achieved in that the disposable use light proofing infusion apparatus of this utility model, comprise perforator, dropping funnel, liquid medicine filter, fluid flow regulator, joint, they are cascaded successively by transfusion catheter, it is characterized in that: described dropping funnel and described transfusion catheter are inside and outside double-layer structure, its skin is made by the black or the brown pvc material of lucifuge, and internal layer is then made by transparent pvc material; Described liquid medicine filter includes the upper and lower two-layer filter membrane that has, and the filter membrane that is positioned at the upper strata is the secondary filter film, and the filter membrane that is positioned at lower floor is for supporting filter membrane.
The utlity model has the lucifuge effect, simple structure, disposable use, safe and reliable, easy to operate, all produce very positive effect to improving clinical treatment efficient, enhancing therapeutic effect and further reducing malpractice.This product needing can be widely used in also being applicable to the venous transfusion that all do not need the lucifuge medicine in the venous transfusion of lucifuge medicine.
Four, description of drawings
Fig. 1, be according to the structural representation that the utility model proposes;
Fig. 2, be A part enlarged diagram among Fig. 1;
Fig. 3, be B part enlarged diagram among Fig. 1;
Fig. 4, be C part enlarged diagram among Fig. 1.
Five, the specific embodiment
Below in conjunction with drawings and Examples structure of the present utility model is further described:
Labelling among the figure: 1, perforator; 2, transfusion catheter; 2-1, transfusion catheter internal layer; 2-2, transfusion catheter skin; 3, dropping funnel; 3-1, dropping funnel internal layer; 3-2, dropping funnel skin; 4, liquid medicine filter; 4-1, secondary filter film; 4-2, support filter membrane; 5, fluid flow regulator; 6, joint.
In the drawings, the disposable use light proofing infusion apparatus of this utility model comprises perforator 1, dropping funnel 3, liquid medicine filter 4, fluid flow regulator 5, joint 6, and they are cascaded successively by transfusion catheter 2.
Wherein, described dropping funnel 3 is inside and outside double-layer structure, and the outer 3-2 of its dropping funnel is made by the black or the brown pvc material of lucifuge, and dropping funnel internal layer 3-1 is then made by transparent pvc material, and this two layers of material is by injection moulding or extrude and be composited; Described transfusion catheter 2 is inside and outside double-layer structure, and the outer 2-2 of its transfusion catheter is made by the black or the brown pvc material of lucifuge, and transfusion catheter internal layer 2-1 is then made by transparent pvc material, and this two layers of material is composited by extruding.
Dropping funnel internal layer 3-1, transfusion catheter internal layer 2-1 are set respectively in dropping funnel 3, transfusion catheter 2 above, just can intercept contacting of medicinal liquid and the outer 3-2 of dropping funnel, the outer 2-2 of transfusion catheter effectively, make medicinal liquid produce chemical reaction, thereby guaranteed the safety of medication with the chemical substance of the outer 3-2 of dropping funnel, the outer 2-2 of transfusion catheter.
In addition, described liquid medicine filter 4 also is provided with upper and lower two-layer filter membrane, and the filter membrane that is positioned at the upper strata is secondary filter film 4-1, and the filter membrane that is positioned at lower floor is for supporting filter membrane 4-2.Here, why to below secondary filter film 4-1, add and support filter membrane 4-2, be to avoid medicinal liquid that secondary filter film 4-1 is caused big pressure and damage secondary filter film 4-1 easily and cause its forfeiture filtration, at this moment, support filter membrane 4-2 just plays the effect to secondary filter film 4-1 support reinforcing.
Above-described only is preferential embodiment of the present utility model.Should be pointed out that to those skilled in the art under the prerequisite that does not break away from this utility model principle, can also make some modification and improvement, this also is considered as belonging to protection domain of the present utility model.
