Profile: Dwyer Precision Products, Inc. offers oxygen safe pneumatic nurse call cords. Our brands are Presscall™, Padcall™, Unicall™, Breathcall™, Mini-Breathcall™ and Adaptacall™. Our Presscall™ nurse call cords are used by patients with sufficient motor skills to either press or lean on the bulb to activate a call. They have an oval shaped, soft vinyl bulb design that prevents them from rolling off the patients bed. Our Breathcall® nurse call cords are oxygen safe and used by patients with no motor skills and are activated by simply breathing into a disposable filter assembly. They have a flexible goose-neck with a universal clamp for mounting.
