The kymograph almost immediately became the central instrument in physiology and physiology education. Throughout the nineteenth and twentieth centuries, researchers and technicians devised many improvements to the device, plus numerous new sensory components to measure a wide range of physiological phenomena such as breathing, muscle movement ...
Recording kymograph: historically, used in human or animal experiments to measure and record data Long extension kymograph: historically, used in or human animal experiments to measure and record data Surface plasmon resonance: Label-free detection of molecule binding. Used to determine kinetic constants of the interaction (k a, k d, K D). Can ...
1866 Henry Hyde Salter (1823-1871) added a kymograph to the spirometer in order to record time while obtaining air volumes. 1879 Gad J. published a paper entitled "Pneumatograph" that described a machine that allowed the recording of lung volume changes.
C. F. Palmer, Ltd was an independent manufacturer of scientific instruments, mostly in the field of physiology. Since 1987 it has been a subsidiary of Harvard Apparatus. [1] The company was founded in London in 1891 by the English mechanical engineer and bicycle maker Charles Fielding Palmer (1864-1938). [2]
In 1847 Ludwig had invented the Kymograph (a mechanical instrument to record heartbeat and other muscle contractions or movements), but of course this was still before the invention of the electrocardiograph. MacWilliam began his research with Ludwig on the hearts of cold-blooded animals such as eels, fish and frogs, and noted a phylogenic ...
Doing spirometry. Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs). It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.
His instrument and technique were later supplemented with a kymograph to record the pressure readings. The Rubin test became a standard test to check the tubes in the investigation of causes of infertility and was claimed to be able to open up tubes in some patients with tubal occlusion. [ 5 ]
Diagram of a typical organ bath preparation. An excised piece of smooth muscle tissue is held in an oxygenated solution in a chamber. The tissue is attached to a lever, which transmits its contraction to a myograph, thus recording the physiological response.
