Abstract
The utility model relates to a double-layer composite light-avoiding transfusion device, comprising a puncture device, an air filter, an automatic drop funnel, a flow adjuster, a medicine liquor filter and a transfusion needle, wherein a protection cap of the puncture device covers the puncture device, the lower end of the puncture device is respectively communicated with the air filter and the automatic drop funnel, the lower end of the automatic drop funnel is communicated with a liquid inlet of the medicine liquor filter by a hose, the hose is provided with the flow adjuster for adjusting the flow and the liquid outlet of the medicine liquor filter is connected with the transfusion needle, characterized in that: the automatic drop funnel, the flow adjuster, the medicine liquor filter and the hose are composed of inner, outer layers. The double-layer composite light-avoiding transfusion device has advantages of simple structure, low cost and convenient operation and simultaneously avoids the bad influences of the material on the medicine liquor and the bad influence of the outer light source on the medicine liquor, thus a certain economic benefit can be obtained and the double-layer composite light-avoiding transfusion device is suitable being widely popularized and used.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of two-layer compound light proofing infusion apparatus.
Background technology
The actuator that the present transfusion device that uses clinically is provided with by an epimere tube for transfusion, Murphy's burette, hypomere tube for transfusion, venipuncture needle and tube for transfusion is from top to bottom successively formed.Though these transfusion devices are simple in structure, easy to operate, but because surfaces such as its tube for transfusion, dropping funnel have printing opacity, light absorptive, when therefore under conventional light, using, the medicinal liquid that the part heliosensitivity is strong can cause bigger injury to the patient in decomposition under the light action, inefficacy even medicinal liquid degeneration.
The utility model content
The purpose of this utility model is the deficiency that overcomes above-mentioned technology existence, and a kind of two-layer compound light proofing infusion apparatus that uses when clinical infusion has the medicinal liquid of requirement to infuse to heliosensitivity that is exclusively used in is provided.
This utility model is that the achieve the above object technical scheme that adopted is as follows:
A kind of two-layer compound light proofing infusion apparatus, it comprises perforator, air filter, automatic dropping funnel, flow regulator, liquid medicine filter and transfusion needle, the perforator helmet covers on the perforator, the perforator lower end is communicated with air filter and automatic dropping funnel respectively by flexible pipe, automatically the dropping funnel lower end is communicated with the liquid medicine filter liquid feeding end by flexible pipe, be useful on the flow regulator of Flow-rate adjustment on the flexible pipe, the liquid medicine filter liquid outlet is connected with transfusion needle, it is characterized in that the automatic dropping funnel of institute, flow regulator, liquid medicine filter and flexible pipe are all by inside and outside two-layer the composition.
The inside and outside two-layer co-extrusion of automatic dropping funnel, flow regulator, liquid medicine filter and flexible pipe is integral described in this utility model.
The internal layer of automatic dropping funnel, flow regulator, liquid medicine filter and flexible pipe is a medical polyvinyl described in this utility model, and skin is the lucifuge material.
The co-extrusion equipment coextrusion mold double-decker that this utility model adopts industry newly to develop, internal layer are that medical polyvinyl, skin are special lucifuge material; Because internal layer adopts the medical polyvinyl material, the special lucifuge material of outer employing, completely cut off the irradiation of external light source to medicinal liquid, make when having medicinal liquid that heliosensitivity requires and can not make drug effect degeneration, reduction or inefficacy because of external light source by this bag transfusion system infusion, simultaneously, because special lucifuge material is the skin at product, can directly not contact with medicinal liquid, do not worry that the lucifuge material produces any harmful effect to medicinal liquid.And the use that this two-layer compound light proofing infusion apparatus is the same with general infusion set can not change the operation of medical workers custom, can not increase medical personnel's workload.
The utlity model has harmful effect simple in structure, with low cost, easy to operate, that avoided harmful effect that material produces medicinal liquid and external light source that medicinal liquid is produced simultaneously, therefore have certain economic benefits, be fit to extensively promote the use of.
Description of drawings
Fig. 1 is this utility model structural representation
Among the figure: 1-perforator helmet, 2-perforator, 3-air filter, the automatic dropping funnel of 4-, 5-flow regulator, 6-liquid medicine filter, 7-transfusion needle.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further
As shown in Figure 1: a kind of two-layer compound light proofing infusion apparatus, it comprises perforator 2, air filter 3, automatic dropping funnel 4, flow regulator 5, liquid medicine filter 6 and transfusion needle 7.Perforator helmet 1 covers on the perforator 2, perforator 2 lower ends are communicated with air filter 3 and automatic dropping funnel 4 respectively by flexible pipe, automatically dropping funnel 4 lower ends by flexible pipe be communicated with liquid medicine filter 6 liquid feeding ends, be useful on the flow regulator 5 of Flow-rate adjustment on the flexible pipe, and this flow regulator 5 is between automatic dropping funnel 4 and liquid medicine filter 6, and liquid medicine filter 6 liquid outlets are connected with transfusion needle 7.The automatic dropping funnel 4 of institute, flow regulator 5, liquid medicine filter 6 and flexible pipe are all by inside and outside two-layer the composition.
The inside and outside two-layer co-extrusion of above-mentioned automatic dropping funnel 4, flow regulator 5, liquid medicine filter 6 and flexible pipe is integral.And the internal layer of dropping funnel 4, flow regulator 5, liquid medicine filter 6 and flexible pipe is a medical polyvinyl automatically, and skin is the lucifuge material.
