What is an Infusion Pump?

Infusion pumps refer to electro-medical instruments that supply nutritive medicated edibles to a patient. This includes medicines, water, pain-relievers, food, etc.

Moreover, nurses carry out under this delivery of fluids monitored amounts in hospitals, private clinics, and medical facilities.

Mostly, the trained medical staff operates these infusion pumps for their smooth operation. Each pump has an inbuilt software integrated with a user-friendly interface.

This user-friendly interface times the amount and duration of nutrient and medication delivery to a patient’s body. In fact, these pumps feature as better alternatives to manual pumps and therefore, most of the medical installations must have it on their premises.

Applications of Infusion Pumps

Infusion Pumps have numerous benefits if used in a hospital or a nursing home. Some of the pertinent applications of infusion pumps are as follows:

Infusion pumps assist in the delivery of medicated and non-medicated fluids in tiny volumes.
These devices feature a bioavailable option of 100%.
With infusion pumps, the medical staff can supply fluid at a pre-programmed rate.
These are safe and risk-free devices working on an automated mode and alarm integrations.
Alarm integrations in infusion pumps inform the users about critical drug penetration, pump breakdowns, tube blockage, etc. They also alert the user about irregular drug interactions or exceed of supply limit in rare cases. All these advantages allow the medical staff to takes timely action.
Infusion pumps allow medical experts to administer the required concentration of drug supply to patients. This makes their task easier as per a patient’s customized medical needs.

Components of an Infusion Pump

An ideal infusion pump is multi-component medical equipment. Some of its significant components are:

Open Loop System: It helps a nurse to set a pre-decided rate of drug delivery to a patient’s body. This decision depends upon the hit and trial method or a mathematical computation technique.
Closed Loop System: In this, a set of transducers monitor drug supply operating in an automated mode.

Types of Infusion Pumps

The Indian markets brim with numerous kinds of infusion pumps. Some of the prominent infusion pumping devices are mentioned below:

General Purpose or Volumetric Infusion Pumps

These pumps find application in the supply of intravascular drugs and blood fluids to the patient.
Such pumps are integrated with a piston or a pump cassette to control the amount of infusion delivered.

Syringe Drivers Infusion Pumps

These infusion pumps have an electronically regulated electric motor for drug supplication.
The medical staff penetrates a syringe in the patient’s body to deliver adequate nutrient-filled substances.
These pumps stand imperative to the size and placement of the selected syringe.

Patient Controlled Analgesia Infusion Pumps

This type of infusion pump features a manual or a hand-held control system for fluid delivery.
It employs pre-requited settings and to monitor the dosage and frequency of drug supply.

Ambulatory Infusion Pumps

Ambulatory infusion pumps are small, compact, and portable medical devices for drug delivery.
These are battery-powered devices with a non-advanced alarm network.
This makes these instruments in the need of stringent monitoring and observation under professional medical staff.
Thus, ambulatory pumps are not recommended to engender critical drug delivery in hospitals. This comprises pump failures, high-risk medications which can adversely impact a patient’s medical condition.

Other Types of Infusion Systems

Some other types of infusion systems incorporated in a medical facility comprise:

Continuous infusion
Intermittent infusion
Patient-controlled infusion
Total parenteral nutrition

Technical Specifications of an Infusion Pump

An infusion pump operates on the following technical specificities:

Operated on a drip rate peristaltic finger pump method.
Should enable the integration of micro and macro drip sets.
Its flow rate should be as follows:
15 drops/ml 3~450ml/hour 1~100drops/min
20drops/ml 3~450ml/hour 1~100drops/min
60drops/ml 1~100ml/hour 1~100drops/min
The drip rate and flow rate accuracy of infusion pumps must be 2% and 10% respectively.
Should have a KVO and purge facility.
Should operate on a supply of 50Hz and an input of 200 to 240 Vac.
Should have a high definition display screen with a user-friendly interface for clarity and precision.
Should be certified and manufactured in medically approved facilities.

Working Principle of Infusion Pumps

Here is a step-by-step working principle for infusion pumps

Performing adequate patient assessments.
Recording the vital signs of a patient’s ailments and diagnosis.
Examine the validity of medical contradistinctions.
Finally, the medical staff infuses recommended medications and fluid into a patients’ body.
The setting of the delivery rate and transmission time of the infused fluid.
Connecting the infusion tubing to the stop-clock integrated with an alarm bell.
Or else, infusing heparin with a syringe pump without hampering the patient’s intravenous line.
Evaluating the administered volume of infusion.
Checking messages on the display screen time and again.
Finally, ensure the timely maintenance of the infusion pump to protect it from wear and tear.
Continue to change its battery or keeping recharging the pump after every use.
