The Most Common Diagnostic Devices

There are various diagnostic devices clinicians use to measure a patient’s health in order to provide diagnoses for different ailments and conditions. It is important when developing a treatment plan for clinicians to have the appropriate medical equipment supplies to properly record the measurement of vital patient information. Diagnostic medical equipment can be found in any outpatient care facility, emergency rooms, as well as intensive care units and inpatient general hospital care. 

Six Most Common type of Diagnostic Devices

Many diagnostic devices are readily recognized, while still others are not. The six most common are listed below:

  • Stethoscopes
  • Sphygmomanometers
  • Ophthalmoscopes
  • Otoscopes

One of the most readily recognized pieces of equipment is the stethoscopes. It lets medical personnel listen to lungs, blood flow, and heart sounds. They can be utilized to diagnose the following:

Although the stethoscope has been around for more than a century, it has gone through some changes to become part of the latest medical diagnostic equipment. Electronic stethoscopes have improved sound quality when making diagnoses. They can also allow multiple people to listen to the same sounds. This is vital when training interns and residents.
