November 20, 2018 – Civco Medical Solutions will present Envision, the next generation of ultrasound probe covers and scan pads, at the 2018 Radiological Society of North America (RSNA) annual meeting, Nov. 25-30 in Chicago.
Envision ultrasound probe covers and scan pads are viral barriers allowing for 100 percent gel-free ultrasound procedures. Radiology physicians and clinicians simply activate Envision with a sterile liquid to perform ultrasound procedures, removing the need for gel. The elimination of gel from procedures utilizing Envision can improve the quality of fine needle aspiration (FNA) specimens, reduces the risk of contamination and simplifies workflow.
Envision covers can help improve the visibility of cells in FNAs by eliminating the need for gel from these procedures. Several studies show the adverse effects gel can have on FNAs:
- Impairs the visibility of cells and interferes with staining of cells1;
- Causes a significant increase in the number of slides with artifacts1;
- Causes widespread cell lysis, increasing the risk of misinterpretation and a false positive diagnosis2; and
- Mimics colloid, creating difficulty in differentiation between artefact and colloid.1,3
The removal of gel when using Envision can help reduce the risk of contamination during needle-guided ultrasound interventions or while scanning non-intact skin. Ultrasound gel has been shown to harbor and spread infection and can:
- Contribute to increasing nosocomial infection, the spread of hospital-acquired infections4,5,6,7;
- Cause bacteria to be introduced into the blood stream6,9; and
- Make the disinfection of sterilization process of devices, including ultrasound probes, less effective.8
The Envision ultrasound probe cover and scan pad enable physicians and clinicians to simplify workflow throughout a procedure.
- A quick-peel, silicone liner adheres safely to the probe face or to the patient’s skin – no gel needed inside the cover or applied to the patient;
- Apply a sterile liquid, such as sterile saline, to the Envision cover or pad, or directly on the patient’s skin, and begin scanning; and
- Pre-cleaning of the ultrasound probe is simplified without gel, before sending to high-level disinfection.
Envision is U.S. Food and Drug Administration (FDA) 510(k) clearance pending.
