As time passes, the medical field continues to evolve into an increasingly sophisticated and efficient method for saving lives. Medicine improves not only in the knowledge but the very technology used to implement it. Through the history of medicine, many instruments have been invented that completely change medical practice. Take a look at these 5 devices that changed the scope of the medical field.

  1. The Doppler Fetal Monitor
    This hand held ultrasound tranducer transfers the fetus heartbeat in prenatal care into an electronic beat that the entire family can hear. Electronic fetal monitors broadcast the sound, offering not only family bonding time but important aspects of the health of the fetus. This allows the mother to eat a special diet or engage in specific exercises that could benefit the health of the fetus.

  2. Heart Lung Machine
    Known in the medical world as a CPB pump, this device takes over the patient's heart and lung capacities during surgery. It ensures the maintenance of circulation and proper oxygen levels so that the doctors can better concentrate on the surgery at hand. It creates a form of extracorporeal circulation in the blood.

  3. EKG
    This device creates a digital interpretation of the electrical activity of the heart over a period of time. It's a great non-evasive way to measure the health of the heart, detecting discrepancies and weaknesses in the heart muscle. Like other types of cardiology equipment, it's been quite effective at gauging the risk of heart disease and heart attacks. A weak heart can readily get a health intervention.

  4. Infusion Pump
    Delivering fluids, nutrients and medications into a patient's circulatory system at a steady rate, this device ensures that a regular does of blood, medication or food in away that minimizes the attention of the staff. This eliminates the possibility for human error with a consistent supply of sustenance.

  5. Electronic Medical Records
    The most recent development in medical equipment, electronic medical records put doctors on the same page when a patient is seen by many medical specialists. This minimizes the miscommunication between the medical community by putting everyone on the same page. Allergies and other medical diagnoses can be better shared. There are privacy concerns, but so long as a patient's confidentiality remains honored, these have not become legal concerns.
