What are elastomeric infusion pumps?
An elastomeric pump, also known as a balloon pump or ball pump, is a medical device used for infusing medication. Depending on the therapy needed, these medications might include antibiotics, chemotherapy, 5FU, cytostatics, analgesics, and local anesthetics.
How does temperature affect the infusion rate of elastomeric devices?
Temperature also affects the infusion rate of elastomeric pumps. Most manufacturers calibrate the pumps at 31-32°C to simulate the normal skin temperature. Any variation in the temperature such as fever, warm suits or blankets would increase the infusion rate (4, 11, 18).
What is elastomeric ball?
An elastomeric device is a device used to deliver medication through your intravenous (IV) line. Medication is put in a balloon-like chamber, and pressure from the balloon delivers the medication at a safe and steady rate.
What are elastomeric pumps made of?
Types of Elastomeric Pump manufactured by Epic Medical: Soft shell pumps are designed with double layer of silicone membranes. The stretched membrane after being crammed with medicine exerts mechanical pressure to administer the contents at a predetermined rate by the flow restrictor.
What is 5FU pump?
Background: Infusional-5-fluorouracil (inf-5FU), administered over 48 hours every 2 weeks, is frequently prescribed for the treatment of gastrointestinal cancers. A portable infusion device (ID) may be used for this purpose to enable treatment at home.
How do you fill an elastomeric pump?
Remove the Fill Port Cap and retain for later use. Remove all air from a 60 ml syringe. Place the end of syringe plunger on work surface. Keeping the unit vertical, grasp syringe barrel or flanges and push slowly downward on the syringe to gradually force fluid into the Elastomeric Reservoir.
What is a large volume infusion pump?
Large-volume pumps (LVPs) are used to accurately deliver liquids through IV or epidural routes for therapeutic and/or diagnostic purposes, normally with rates from 0.1 to 999 mL/hr or higher.
How is 5-fluorouracil?
5-fluorouracil can be administered by intravenous injection as bolus, infusion or continuous infusion for up to several days.
What are volumetric pumps?
Volumetric infusion pumps (VIP) are medical devices capable of delivering continuous and very specific amounts of fluids at very slow to very fast rates. Infusion pumps are commonly used to control the flow of intravascular drugs, fluids, whole blood, and blood products to patients.
How reliable are Elastomeric pumps?
In vivo reliability of elastomeric pumps is different than in vitro. In the event of early insufficient postoperative perineural analgesia, an absence of deflation of the elastomeric pump must be considered. We recommend weighing these devices every 3 h during the first 24 h of infusion.
How many flow rate errors are there in Elastomeric pumps?
Error of elastomeric pump flow rates. Percentages of flow rate errors of 430 consecutive devices are shown (300 Easypump, empty circles, and 130 Infusor LV5, filled circles). In the inferior part of the double abscissa, devices are presented chronologically from the beginning of the follow-up (number 1) to its termination (number 430).
Do elastomeric perineural pumps improve postoperative analgesia?
Postoperative analgesia via continuous perineural infusion of local anesthetics compares favorably with systemic analgesia. Elastomeric pumps increase patient satisfaction compared with electronic models. In in vitro investigations, infusions remained within 15% of their designated set rates.
How do you calculate global elastomeric pump flow rate?
Global elastomeric pump flow rate was computed as the difference between its first weight on the surgical ward and the last one, divided by the time (in min) between these two measures.
