Abstract: An antimicrobial metallized thin film is provided that can be quickly and easily attached to surfaces of objects. This film includes a polymer substrate onto which a metallized layer is formed. The metallized layer comprises an exposed antimicrobial metal physical contact surface. Ions from this physical contact surface destroy the viral coating and ribonucleic acid of contacting viruses rendering the viruses inactive and noninfectious. The film can be attached via an adhesive layer disposed between and in contact with the polymer substrate and the communal surface. This arrangement allows the film to economically refurbish communal surfaces with a film overlay rather than completely replacing communal surfaces with antimicrobial materials. The film mitigates the likelihood of viruses such as coronaviruses, noroviruses, rhinoviruses, and the like from spreading due to contact with the refurbished communal surfaces.

Abstract: A system and method for calibrating an IV pump infusion system tube comprises a fluid source, an infusion system comprising, an IV pump, a drive unit, a chamber with known constant volume, a control unit, and IV tubing with a known inner diameter tolerance, and a sensor and floating detection object. The system administers medicinal fluid, calculates the flow rate of the medicinal fluid in the chamber by measuring the time the floating detection object and medicinal fluid rises in the chamber, compares the calculated flow rate with a set flow rate of the IV pump input in the control unit prior to infusion, and adjusts the IV pump and flow rate based on the compared deviations for more accurate delivery to a patient. This configuration may provide a more precise delivery rate of medicinal fluid, preventing harm to the patient and waste of medicine.

Abstract: A method that combines injection molding and extrusion is disclosed. First, a molten material is injected into a mold via an injection gate, the mold comprising a first portion and a second portion.
