The invention of the otoscope is credited to Sir Francis Bacon, an English philosopher and statesman, in the early 17th century. His original design was a candle-based instrument, which has since evolved into the contemporary, more advanced otoscope used in medical practice today. This device has been instrumental in improving the accuracy of ear examinations and the diagnosis of ear ailments.
7. ventilator

A ventilator assists individuals with compromised or insufficient respiratory function. It is commonly used in hospitals and intensive care units to support patients who are unable to breathe adequately on their own. A ventilator operates by delivering a controlled mixture of oxygen and air into the patient's lungs and removing carbon dioxide, thereby ensuring adequate oxygen supply and maintaining proper carbon dioxide levels in the bloodstream.

The concept of mechanical ventilation dates back to the early 20th century, with significant contributions from Dr. George Poe and Dr. James A. Cunningham. They developed early versions of mechanical ventilators, which were essential during the polio epidemic of the 1950s, marking the beginning of modern mechanical ventilation. Over time, ventilators have undergone extensive technological advancements, resulting in more efficient and user-friendly designs.
8. reflex hammer

The reflex hammer is a simple yet essential medical instrument used by neurologists and physicians to test and assess the body's reflexes. It typically consists of a long, slender handle with a rubberized head at one end. The reflex hammer is employed to strike specific areas on the body, such as the knee, elbow, or ankle, eliciting involuntary muscle contractions, or reflexes. These responses help doctors evaluate the integrity of the nervous system and detect abnormalities or underlying neurological conditions.

The invention of the reflex hammer is credited to Sir William Osler, a prominent Canadian physician, who introduced it in the late 19th century. His innovation greatly enhanced the precision of assessing reflexes and became an integral part of physical examinations. Over time, the reflex hammer has undergone various design modifications, though its fundamental purpose remains unchanged.
