Problems solved by technology

This kind of light-shielding polyvinyl chloride raw material is blended by adding light-shielding powder on the basis of ordinary polyvinyl chloride raw materials. The light-shielding powder used includes two small molecular substances, toner and ultraviolet absorber, which are easy to dissolve during the infusion process. Precipitation due to immersion in the medicinal liquid, resulting in discoloration of the medicinal li

Embodiment Construction

[0013] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the advantages of the present invention will become clearer and easier to understand.

[0014] exist figure 1 Among them, the low-adsorption multi-layer co-extruded light-proof infusion set of the present invention includes a puncture device 1, an air filter 2, a drip funnel 4, a flow regulator 5, and a liquid medicine filter 6, which are connected in series by an infusion catheter 3. It is characterized in that the infusion catheter 3 and the dripping funnel 4 adopt a double-layer structure, the material of the outer layer 7 is polyvinyl chloride added with light-proof powder, and the material of the inner layer 8 is thermoplastic polyolefin or thermoplastic polyurethane, such as figure 2 shown. exist figure 1 On the basis of the structu...

Abstract

The invention relates to a low adsorption multi-layer co-extrusion light-proofing infusion apparatus, comprising a puncture, an air filter, a dropping funnel, a flow regulator, and a liquid filter with infusion catheter linking the above mentioned parts in between. The invention is characterized in that the infusion catheter and the dropping funnel adopt a multi-layer structure, and the outer layer is made of medical PVC with additive light-proof powder, the inner layer is nonpolar medical TPE thermoplastic elastomer). The invention eliminates the possibility for the light-proof system to precipitate from the infusion apparatus, and meets the need of clinical light-proofing infusion safely and effectively. The inner layer does not absorb the medical liquid at all, so that wastes of medicine are avoided. The product of the invention is simple in structure and easy to use as ordinary infusion apparatus.

Description

Technical field [0001] The invention relates to a light-proof infusion set, in particular to a pipeline and a drip funnel with a multi-layer structure, which belongs to the technical field of medical devices. technical background [0002] In clinical practice, some medicines need to be transfused under light-proof conditions, such as sodium nitroprusside, nitroglycerin, vitamin B2, etc. Common infusion sets cannot meet this infusion requirement, therefore, infusion sets with light-proof function are needed. The earliest light-proof infusion set was wrapped with opaque materials. Although it can protect the infusion set from light, it is also cumbersome to operate, which is not conducive to observing the dripping speed and bubbles. Appeared again afterwards with light-proof polyvinyl chloride raw material, a kind of by the black or brown raw material of light-proof, the light-proof infusion set that the structure of making is similar to common infusion set. This kind of ligh...
