Presentation of Dieulafoy’s aspirator
On 2 November 1869, Adolphe Gubler presented an aspirator to the Academy of Medicine, developed to Georges Dieulafoy’s specifications. Manufactured by Robert and Colin, it combined a fine needle with a previously created vacuum to investigate or evacuate fluid collections.[1]

Contributions to medicine
- A simple mechanism: a syringe, needles or cannulas, and stopcocks allow a vacuum to be created and then applied. Fluid movement relies on this suction; the instrument’s value lies in the practical arrangement of its components.[2]
- A link between diagnosis and treatment: Dieulafoy proposes collecting fluid to determine its nature and considering evacuation. His note includes joint and pleural effusions among its applications.[1]
- A clinical approach: his textbook links the description of diseases with diagnosis, prognosis and treatment. His teaching combines bedside observation with pathological knowledge and the investigations available in his time.[3]
Documented anecdotes
An innovation immediately disputed
In his 1873 treatise, Dieulafoy describes priority claims arising in France and abroad after the presentation. He emphasises the combination of fine needles with a vacuum created in advance. The account also reveals the human side of innovation: its advocates must publish observations, defend their choices and persuade their colleagues.[5]
