On April 11 1899, her patent was approved with the publication number ‘US622848A.’ In the patent application, she states how it is to be used: “The operator inserts the nozzle in the rectum and holds the cylinder by placing the fingers of the same hand in the rigid arm of the handle. The handle is in a position away from the cylinder before injecting the medicine. The extension prevents the fingers from slipping off the rigid arm. The handle can be drawn into a position near to the cylinder while injecting the medicine by the use of one hand, thereby enabling the operator to use the syringe-upon himself without the aid of an assistant. Death Letitia Mumford Geer passed away in 1935 in Kings County New York at the age of 83.<ref name=":0" />
