Problems solved by technology

[0002] When conventional infusion sets are used clinically to infuse photosensitivity drugs, the drugs are easily decomposed under the action of light, which affects the curative effect, and even produces negative effects. In the bucket, through the infusion set catheter and the inner surface of the dripping funnel, it is in direct contact with the liquid medicine, which is prone to decolorization under the infiltration of the liquid medicine, resulting in toxic and side effects, and it is difficult to guarantee the safety of patients.

Embodiment 1

[0011] The outer surface of the light-proof infusion set catheter (8) is colored by atomizing and spraying light-proofing agent solution, which consists of one, two or more nozzles (1), isolation cover (4), exhaust pipe (5), residual liquid It is composed of a return pipeline (6) and a drying device (7). According to the requirements of the degree of light protection, the proportion of light protection agent in the solution is between 0% and 30%. The solvent of light protection agent solution is composed of cyclohexanone, butanone, acetone, tetrahydrofuran, n-hexane, methylene chloride, One, two or more of ethyl chloride, methanol, isopropanol, butanol, ethylene glycol, fluorodichloroethane, freon, petroleum ether, solvent oil, etc. The nozzle (1) is provided with a compressed air inlet pipe (2) and a light shielding agent solution liquid inlet pipe (3). Under the action of compressed air, the light shielding agent solution is atomized and evenly sprayed on the conduit (8) thr...

Embodiment 2

[0013] The structure and implementation of the second embodiment are basically the same as those of the first embodiment, except that the second embodiment is the atomization spraying and coloring process of the dropping funnel (9).

Abstract

The invention relates to a coloring technology for outer surfaces of a catheter and a drip chamber of a light resistant infusion apparatus and belongs to the technical field of medical instruments. The coloring technology is characterized in that the outer surfaces of the catheter and the drip chamber of the light resistant infusion apparatus are colored by adopting a coloring mode of atomizing and spraying light resistant agent solution; and a device for coloring consists of one, two or more spray nozzles, an isolating hood, an exhaust pipeline, a residual liquid reflowing pipeline and a drying device. A light resistant agent accounts for 0-30 percent of the solution; and solvent of the light resistant agent solution consists of one, two or more of cyclohexanone, butanone, acetone, tetrahydrofuran, normal hexane, dichloromethane, dichloroethane, methanol, isopropanol, butanol, ethylene glycol, dichlorofluoroethane, freon, petroleum ether, solvent oil and the like. Compressed air inlet pipelines and light resistant agent solution pipelines are arranged on the spray nozzles; and under the action of compressed air, the light resistant agent solution is atomized and sprayed on the surfaces of the catheter or the dipper chamber by the spray nozzles and is naturally dried or baked to finish the coloring.

Description

Technical field [0001] The invention relates to a coloring process for the outer surface of a catheter of a light-proof infusion set and a drip funnel, and belongs to the technical field of medical devices. Background technique [0002] When conventional infusion sets are used clinically to infuse photosensitivity drugs, the drugs are easily decomposed under the action of light, which affects the curative effect, and even produces negative effects. In the bucket, through the infusion set catheter and the inner surface of the dripping funnel, it is in direct contact with the medicinal liquid, and it is easy to cause decolorization under the infiltration of the medicinal liquid, resulting in toxic and side effects, and it is difficult to guarantee the safety of the patient. Contents of the invention [0003] The invention provides a coloring process for the outer surface of the catheter and the dripping funnel of a light-proof infusion set. It has the characteristics of simp...
