The correct spelling of "External Infusion Pump" is /ɪkˈstɜːr.nəl ɪnˈfjuːʒən pʌmp/. The word "external" is spelled with an "e" instead of an "a" because it is derived from the Latin word "externus." On the other hand, "infusion" is spelled with a "u" instead of an "o" because it is derived from the Latin verb "infundere." Finally, "pump" is spelled as expected, but its second syllable is stressed (/pʌmp/), which means it receives greater emphasis when spoken.
An external infusion pump refers to a medical device designed to deliver fluids such as medications, nutrients, or fluids to patients in a controlled manner, and is typically used for long-term therapies. The pump is called external because it is a device that is worn externally, often attached to the patient's body through a tube. It is commonly used when a patient requires a continuous supply of fluids or medications that cannot be delivered through traditional oral or intravenous methods.
The external infusion pump consists of several components such as a reservoir, which holds the fluid or medication, a pump mechanism that controls the rate of flow, and a controller that allows healthcare professionals to adjust and monitor the delivery settings. The device operates by means of a motor-driven piston or peristaltic mechanism, which pushes the fluid or medication through the tubing and into the patient's body.
This type of pump is often programmable, allowing precise control over the rate at which the medication or fluid is delivered. It can also be equipped with safety features, such as alarms or alerts that notify healthcare providers if there are any issues with the infusion, such as blockages or low fluid levels. This ensures that patients receive the correct amount of medication or fluid at the right time, minimizing the risk of complications or errors.
Overall, external infusion pumps play a crucial role in providing appropriate and reliable delivery of medications and fluids to patients who require long-term therapy, allowing them to maintain their health and well-being.
