File:Cadet Nurse Corps holding a glass syringe.png

Summary[edit]

Notes[edit]

This image is incorrectly used in multiple places on the Internet to illustrate either Letitia Mumford Geer or the self-administered enema syringe she patented, and the image shows neither. No image of Letitia Mumford Geer is known to exist. An illustration of her 1895 syringe is in her patent application. There is a lot of misinformation about Letitia Mumford Geer both in English Wikipedia and other Internet sites. She was not married, she did not start a manufacturing company. Most importantly, she did not invent the modern all-glass syringe. She received a patent for a self-administered enema using a novel hook-shaped finger grip that slid past the barrel of the syringe so it could be self-administered with one hand. In previous models the end of the plunger was too far from the barrel to self-administer with one hand. The novelty was the U-shaped plunger grip. Glass barrel syringes had been in use prior to 1895, when she submitted her patent. Alexander Wood designed the modern all-glass syringe in 1851.
