Breakthrough as medics create new vibrating catheter that could help 90,000 patients in Briton each year
A new device that uses soundwaves to ‘shake’ away bacteria could protect thousands of hospital patients from painful and potentially life-threatening bladder infections.
It is no secret that Catheter-Associated Urinary Tract Infections (CAUTIs) which are extremely virulent, are very dif cult to treat and eradicate.
National evidence-based guidelines for preventing healthcare-associated infections (HCAI) in National Health Service (NHS) hospitals in England were commissioned by the Department of Health (DH) and developed during 1998-2000 by a nurse-led multi-professional team of researchers and specialist clinicians.
The predominant form of life for the majority of microorganisms in any hydrated biologic system is a cooperative community termed a “biofilm.” A biofilm on an indwelling urinary catheter consists of adherent microorganisms, their extracellular products, and host components deposited
Effective Prevention of Microbial Biofilm Formation on Medical Devices by Low-Energy Surface Acoustic Waves
Low-energy surface acoustic waves generated from electrically activated piezo elements are shown to effec- tively prevent microbial biofilm formation on indwelling medical devices. The development of biofilms by four different bacteria and Candida species is prevented when such elastic waves
Surface acoustic waves increase the susceptibility of Pseudomonas aeruginosa biofilms to antibiotic treatment
Bacterial urinary tract infections resulting from prolonged patient catheterization have become a major health problem. One of the major issues is bacterial resistance to antibiotic treatments due to biofilm formation inside the catheters, thus enhancing the search for alternative treatments.
Biofilms are bacterial communities embedded in extrapolysaccharide matrix which protects them from hostile environmental conditions. Biofilms are extremely resistant to antibiotics treatments and are a major cause of medical device-associated infections. Therefore immense efforts are being made in a search
