One-way valve for chest drainage: Experimental evaluation

Válvula unidireccional para drenaje torácico: Valoración experimental

Carrera, Carlos - Iriondo, Nilsa - Rubí, Francisco - Cestaro, Leticia

Resumen:

The present work discusses the design and usage of a unidirectional valve for drainage of the pleural cavity in experimental surgery. It is designed in a duckpeak shape, with 2 latex valves, 0.5 mm thick and 5.05 cm2 surface. Its critica! leve! of opening ranges between a pressure of 0.3 and 1 centimeter of water. Its output depends upon the gauge of the adapter (a 6 mm tube was used) and upon the fluid or gaseous supply to be drained. It has been tested on 15 animals with hypertensive pneumothorax, either provoked or after carinal surgery. It has proved to be efficient and easy to manage. Possible clínica! applications of this device are suggested.


Se analiza la construcción y la utilización de una válvula unidireccional para el drenaje torácico en cirugía experimental. Diseñada en forma de pico de pato, con 2 valvas de látex de 0.5 mm de espesor y 5.05 cm2 de superficie, su nivel crítico de apertura oscila entre 0.3 y 1 cmde agua. Su gasto depende del calibre del adaptador (se usó un tubo de 6 mm) y de la oferta líquida o gaseosa a drenar. Testada en 15 animales con neumotórax hipertensivo provocado o luego de cirugía carinal, se mostró eficaz y de simple manejo. Se sugieren posibles aplicaciones clínicas de la misma.
