What are Medical Infusion Pumps & Their Types?

An infusion pump helps in the infusion of fluids, medication or nutrients into a patient’s circulatory system. Medical infusion pumps can infuse fluids in ways that would be impractically expensive or unreliable if performed manually by nursing staff. Due to this, infusion pumps are used in Hospitals.

Infusion pumps can deliver fluids in small or large quantity and are used to deliver medications, nutrients, and other important liquids into a patient’s body. Depending on their functionality, infusion pumps are divided into following 4 categories:

IV Infusion Pumps: Intravenous therapy is the therapy of infusion of liquid substances directly into the vein. Intravenous means within the vein. Intravenous infusions are commonly used as drips. The intravenous way is the fastest way to deliver medications and fluids throughout the body. Intravenous therapy can be used for fluid administration such as dehydration to deliver medications, correct electrolyte imbalances, and blood transfusions.

Syringe Pumps: A syringe pump or syringe driver is a small infusion pump which is used to deliver small amounts of fluids in patients gradually. They are also used for biomedical and chemical research. Their applications include electrospinning, electrospraying, microfluidics, microdialysis, organ/tissue perfusion and fluid circulation, etc. Other uses of syringe pumps are to continuously deliver painkillers, medications to suppress vomiting and nausea, etc.

As the medication is delivered in small amounts, therefore there is no need for multiple tablets. People who have swallowing problems will get help from this. Area of its administration is limitless. The intravenous route is the fastest method for delivering medications and fluids throughout the body. Intravenous therapy may be used for administering fluids like correcting dehydration, electrolyte imbalances, delivering medications and blood transfusions.

Feeding Pumps: Feeding pumps are the type of Enteral pumps which helps you to meet the nutritional needs of your baby or person who is not able to eat with his/her mouth. Doctors prescribe this method to deliver life-saving nutrients in the patient’s stomach. For some people, this slowly metered infusion method may be tolerated in a better manner as compared to the gravity or bolus methods.

PCA Pumps: Patient-controlled pumps provide infusions in a pre-programmed manner. They usually have a pre-programmed ceiling to protect you from intoxication. The rate of a patient-controlled pump is controlled by a pressure pad or button which can be activated by the patient. Repeated small doses of opioid analgesics are delivered in such a way that the device is coded to stop the administration before it reaches the point of hazardous respiratory depression.

Based on the functionality of each type of infusion pumps, you can buy medical infusion pump for your hospital from an online or offline vendor. These days to cut short the medical expenses, hospitals are buying refurbished infusion pumps. These devices are not only very reliable functionality wise but are also available at a cost 60-70% less than the new ones. So, buying refurbished infusion pumps is definitely a smart move.
