Abstract

The invention relates to the technical field of medical drug-containing catheter equipment, in particular to a drug-containing catheter coating device. The device comprises a drug storage tank provided with a material return port, a coating container, a clamp and a gas pumping device. The coating container communicates with the drug storage tank through a coating pipeline, the coating container is provided with a discharging port communicating with the material return port, and the coating container is provided with an opening allowing a catheter to be inserted in. The clamp is arranged at the opening and is used for fixing the catheter. The gas pumping device communicates with the drug storage tank through a first gas pipe and can pump gas into the drug storage tank or pump gas out of the drug storage tank. According to the drug-containing catheter coating device, the probability and area of exposure of drug liquid are greatly reduced, the drug liquid is prevented from being polluted, and volatilization of the drug liquid is greatly reduced; and meanwhile, volatilization of solvents in the drug coating process is reduced, and waste of the solvents is reduced.

Description

technical field [0001] The invention relates to the technical field of medical drug-containing catheter equipment, in particular to a drug-containing catheter coating device. Background technique [0002] The most important thing in the production process of medical drug-containing catheters is to coat a layer of drugs on the catheters. In order to make the drugs with specific effects adhere to the outer surface of the medical catheters, it is necessary to dissolve the drugs in a solvent to make a solvent-containing catheter. When the drug solution is applied, the solvent corrodes the surface of the catheter, and its medicinal ingredients adhere to the surface of the catheter, and then the solvent evaporates by itself, and the surface of the catheter is air-dried and adhered to the drug. Therefore, during the coating process, this solvent exists and needs to be volatilized, but volatilization is difficult to control. In the prior art, when producing a drug-containing cathet...
