A novel one-step lens cleaning device using air and water flow for endoscopic surgery.

In a surgical operation requiring endoscopy, it is essential to obtain a clear endoscopic view. However, it is often disturbed by the contamination on the lens during the surgery. No device can clean the lens surface simply and completely. Many surgeons are hampered by the impaired view and the distraction by the repeated cleaning of the lens. Therefore, we developed a novel endoscope cleaning device to address this problem. The device was made of 3D-printed rubber-like plastic. It contains a syringe filled...

Increased Detection Of Carbapenemase-Producing Enterobacteriaceae On Post-Clean Sampling Of Burns Units Wet Surfaces.

Wet surface biofilms are a potential reservoir for multidrug-resistant Gram-negative organisms, including carbapenamase-producing Enterobacteriaceae (CPE). Recognition of environmental sources is important in reducing secondary patient transmission. We report the increased detection of bla-IMP-4+ CPE in environmental samples from floor drains in Burns Unit shower rooms, when collected following cleaning as compared to pre-cleaning. We propose that disruption of biofilms during cleaning may account for the i...


Development of an industrial ultrasonic cleaning tank based on harmonic response analysis.

A small industrial ultrasonic cleaning tank, which is one of the best-selling models, had cleaning problems. Customers sometimes complained that the tank did not completely clean all objects, or that some objects got damaged, so a solution to the problem was urgently needed. The tank has a volume of 18 L, frequency of 28 kHz, eight horn style PZT4 transducers, and a total electric power of 400 W. The cleaning occurs from the cavitation effect which corresponds to an increase in the acoustic pressure. ...

Pillars or Pancakes? Self-cleaning surfaces without coating.

Surfaces that stay clean when immersed in water are important for an enormous range of applications from ships and buildings to marine, medical and other equipment. Up till now the main strategy for designing self-cleaning surfaces has been to combine hydrophilic/hydrophobic coatings with high aspect ratio structuring (typically micron scale pillars) to trap a (semi-)static water/air layer for drag and adhesion reduction. However, such coating and structuring can distort optical properties; get damaged in h...

The goal was to prevent microbial transmission to patients in a clinical setting after two cases of sepsis caused by multi-drug ...

In situ biofilm removal from air cathodes in microbial fuel cells treating domestic wastewater.

One challenge in using microbial fuel cells (MFCs) for wastewater treatment is the reduction in performance over time due to cathode fouling. An in-situ technique was developed to clean air cathodes using magnets on either side of the electrode, with the air-side magnet moved to clean the water-side magnet by scraping off the biofilm. The power output of the magnet-cleaned cathodes after one month of operation was 132 ± 7 mW m, which was 42% higher than the controls with no magnet (93 ± 4 mW...

Self-cleaning superhydrophobic nanocomposite surfaces generated by laser pulse heating.

Micro- and nanostructured surfaces are known to induce anti-wetting and self-cleaning properties. However, traditional formation of these structures is difficult and requires high-resolution micro- and nanofabrication methods. Here, we demonstrate a facile method for the formation of superhydrophobic self-cleaning surfaces by laser pulse heating of a carbon nanotube-polymer composite. Laser treatment exposes a carbon nanotube network which controls surface wetting properties. Advancing and receding contact ...

How clean is your house? A study of house dust mites, allergens and other contents of dust samples collected from households.

Household dust contains an array of constituents, including house dust mites (HDM) and the HDM allergen, Der p 1, which can cause sensitivities such as asthma and eczema. Vacuuming can help alleviate symptoms, yet little is understood about cleaning behaviour in different households. This pilot study investigated the contents of dust from four household types (students; over 65 s; and families with and without pets). This was then related to cleaning behaviours and perceptions of cleanliness. Our investiga...

Optimizing seed processing techniques to improve germination and sowability of native grasses for ecological restoration.

Grasslands across the globe are undergoing expansive degradation due to human impacts and climate change. If restoration of degraded native grassland is to be achieved at the scale now required, cost effective means for seed-based establishment of grass species is crucial. However, grass seeds present numerous challenges associated with handling and germination performance that must be overcome to improve the efficiency of seeding. Previous research has demonstrated that complete removal of the palea and le...

The presence of fecal test soil protects bacteria during cleaning/disinfection.

Reusable medical devices (RMDs) must be reprocessed between uses to render them safe for each use and each patient. Cleaning used devices removes organic and inorganic soil making them either safe for reuse or ready for disinfection/sterilization depending on the device. Although cleaning is an important step in a RMD's life cycle, it is not always a priority during device design. In addition, when performing cleaning validation, it is recommended that the manufacturer takes into consideration, what the mos...

A "hasty" 1-min cleaning of a blood droplet was simulated using the thre...

Occupational exposure to cytotoxic drugs: the importance of surface cleaning to prevent or minimise exposure.

Healthcare workers who prepare or administer cytotoxic agents run the risk of exposure, and the risks for health are real even at doses lower than those applied in cancer patients, because, in theory, no dose is safe. The most common and problematic route of exposure is through the skin, especially as work surfaces can remain contaminated even after cleaning. This pilot study aimed to demonstrate the importance of having an effective surface decontamination protocol by determining surface contamination with...

A test method to assess the contribution of fluid shear stress to the cleaning of reusable device surfaces.

Adequate cleaning of reusable medical devices is critical for preventing cross-infection among patients. For reusable medical devices, cleaning using mechanical brushes and detergent may not be sufficient to completely remove the infectious contaminants from the surfaces. This study evaluates the role of fluid flow-induced shear stress in the detachment and removal of contaminants from device surfaces. A stainless-steel test coupon, acting as a surrogate for a device surface, was coated with artificial clot...
