In order to sell a piece of equipment you must know it like the back of your hand. This is true for any sales job, especially medical sales.
An Infusion Pump (perfusor) infuses fluids, nutrients and medication keen on patient's circulatory system. It is usually used as intravenous, subcutaneous, arterial and epidural infusion.
It can give a patient fluids in many different ways that is productive for nurses. For example; an Infusion Pumps is so exact that it can give 1mL per hour, or an injection every minute with repeated boluses request, up to a maximum number per hour.
Infusion is made up of one of four different types, giving patients a scaled and controlled infusion such as:
- Continuous Infusion: gives small pulses of infusion (20 nanoliters and 100 microliters).
- Intermittent Infusion: timings are programmable. Alternating low infusion, to keep the cannula open.
- Patient-controlled: it avoids intoxication with a preprogrammed limit. Patient controlled the analgesia. (PCA)
Total Parenteral Nutrition: it gives infusion as normal mealtimes.
The Infusion Pump has 2 main types: large volume and small volume. A large volume pump pumps nutrient solution sufficient to feed a patient. It is use for peristaltic pump. Small volume infuses hormones like insulin, any kind of medicine, opiates. It operate whit a computer controlled motor giving the exact amount of medicine.
The pumps have different sizes and are design to be portable in some cases or used only in hospitals.
Infusion pumps in some places are made by classic medical improvisation, giving a high risk to the patient. The pressure varies by the size and height of the patient. Only trained people should work with this type of situation. The high pressure, in this cases, can help control the flow, because of the small restrictor orifice where the flow pass through.
An Air filter is very essential, to control the air in the veins. If the air gets up to .055 cm³ per kilogram of the weight of the patient, it will kill the patient.
The smallest infusion pumps employ "Osmotic Power", which is a bag of salt solution that absorbs water by a membrane, bump its volume.
Several safety features on some pumps are:
- Certified without any failure.
- Full batteries charge.
- Anti free flow to prevent any blood draining from the patient.
- A sensor for a down pressure.
- A detector for 'air in line"
- An Up Pressure sensor
