Continuous anodic oxidation equipment and technology of single-sided anodic oxidation porous infusion device filter membrane

Abstract

The invention discloses a continuous anodizing equipment and process for a filter membrane of a single-sided anodic oxidation porous transfusion device, wherein the continuous anodizing equipment includes an unwinding device, a winding device, an anodic oxidation electrolyte tank, an overflow tank, and an anode power supply roller , cathode and electrolyte pump; the unwinding device and the rewinding device are respectively set on both sides of the anodizing electrolyte tank, the aluminum foil roll is set on the unwinding device, and the anodized aluminum foil is rewound on the rewinding device; The launder is set inside the anodic oxidation electrolyte tank; the anode power supply roller is pressed on the aluminum foil between the unwinding device and the winding device, so that the lower surface of the aluminum foil is in contact with the surface liquid level of the overflow tank, and the anode power supply roller supplies power to the aluminum foil The cathode is arranged inside the overflow tank; the electrolyte pump pumps the electrolyte in the anodic oxidation electrolyte tank into the overflow tank. The invention realizes the continuous anodic oxidation process, and in the process, can completely protect the non-electrolytic surface, and has the ability of continuous anodic oxidation.

Description

technical field [0001] The invention relates to a single-sided anodic oxidation porous infusion device filter membrane continuous anodic oxidation equipment and process. Background technique [0002] Intravenous fluids are the most common method of drug delivery therapy. Since intravenous infusion directly contacts the blood circulation system and directly affects the safety of life, infusion sets are strictly managed according to three types of medical devices. Particle pollution is an unavoidable problem in the infusion process, and a special filter device needs to be added to the infusion set. The national standard GB8368 (2005) and the pharmaceutical industry standard "YY 0286.1-2007" clearly require the infusion set to be equipped with a filter device to filter micron-sized particles. Actual medical practice and research have shown that some special drugs and patient groups require a filter membrane with higher filtration accuracy. The US "Standards of Nursing Practi...

Problems solved by technology

In this method, although the aluminum foil is covered with a non-conductive film, it still goes deep into the electrolysis as a whole, which increases the chance of leakage
