This apparatus was used in the pneumatic project of Dr.Thomas Beddoes, scientific research, the Pneumatic Medical Institution in Bristol, on the potential use of gases in pulmonary diseases. Analyzing the studies and experiments pneumatic of James Watt , focusing on his only work written in collaboration with Dr.Thomas Beddoes, Considerations on The Medicinal Use of factitious Air and Manner of Obtaining them in Large Quantities in Two Pats, 1794. At the same time we analyze the thinking of pneumatics Dr.Joseph Black English (1728 - 1799), Joseph Priestley (1733-1804) and Dr.Erasmus Darwin (1731-1802), who contributed to the study of gases developed by James Watt. This analysis strengthens our argument that these studies have worsened the pneumatic medicine / Nesta dissertação abordamos os estudos pneumáticos, realizados por James Watt (1736-1819) que o conduziram na confecção de um aparato portátil de inalação de gases em colaboração com as terapias médicas do Dr.Thomas Beddoes (1760 - 1808). Este aparato foi utilizado no projeto pneumático do Dr.Thomas Beddoes, de investigação cientifica, o Pneumatic Medical Institution, em Bristol, sobre a potencialidade de utilização dos gases em enfermidades pulmonares. Analisando os estudos e experimentos pneumáticos de James Watt, enfocando sua única obra escrita em colaboração com Dr.Thomas Beddoes, Considerations on The Medicinal Use of factitious Air and Manner of obtaining them in Large Quantities in Two Pats, de 1794. Ao mesmo tempo analisamos o pensamento dos pneumáticos ingleses Dr.Joseph Black (1728 1799), Joseph Priestley (1733-1804) e Dr.Erasmus Darwin (1731-1802), que contribuíram com os estudos dos gases desenvolvidos por James Watt. Esta análise fortalece nosso argumento de que estes estudos potencializaram a medicina pneumática
