Original technical drawing from 1913, hydrotherapeutic water bath made by Carl L. Baumgaertner, medical apparatus

Rare original technical drawing (59 x 58 cm including frame) from 1913, created by Carl L. Baumgaertner. The drawing shows a detailed design of a medical-therapeutic water bath with a mechanical relief device – a historical device used for hydrotherapy in sanatoriums and orthopedic clinics.

The drawing includes cross-sections and longitudinal sections, precisely executed at a scale of 1:10, with handwritten labels and the original workshop stamp. An exceptional document of early medical technology history and an impressive collector's item for enthusiasts of anatomy, engineering, medical history, or historical technical drawings.

This drawing documents a hydrotherapeutic treatment device from the period around 1910–1915. Such devices were used in orthopedic clinics, health resorts and sanatoriums to treat patients in warm water, relieve pressure on the spine or perform exercises under buoyancy.

The system shown combines:
a water basin
a mechanical deployment framework
Pulleys, sheaves and counterweights
a suspension system for partial relief of the body

These constructions were part of early physical therapy, influenced by Kneipp's hydrotherapy, Hoffa's orthopedics, and the emerging field of rehabilitation medicine. The drawing is a typical example of the connection between engineering and medicine in the early 20th century. The stamp "Carl L. Baumgaertner 9.4.1913" indicates a designer or workshop foreman who likely worked for a medical-technical institution or a sanatorium.
