A method of cleaning a contaminated surface, such as cleaning the elongate interior lumen of an endoscope contaminated with flesh, bone, blood, mucous, faeces or biofilm, said method comprising the steps of: providing a suspension of solid particles in a liquid to said contaminated surface, and flowing said suspension along said surface thereby to remove contaminant from the surface. The suspension is preferably a paste, where the solid material may be e.g. crystals of a salt, silicon oxide or organic material. The paste preferably has a solid fraction between 5 and 55%. A rheology modifier may be present.

Systems and methods for adhering biofilm to a lumen

The invention relates to compositions and methods for reducing biocontaminant (for example flesh, blood, mucous, faeces or biofilm) on a surface, such as an endoscope surface. The compositions are viscoelastic and of low lubricity, having the following properties at 21° C.: a rotational yield point between 140% strain and 300% strain; a peak viscosity between 550 Pa·s and 2000 Pa·s; an oscillatory flow point between 250 and 700% strain; and a coefficient of friction μ which has a maximum value (preferably 0.06 or greater) in the viscoelastic liquid's elastohydrodynamic region.

Endoscope cleaning with viscoelastic liquid

Described herein is a disinfectant system in the form of an autonomous device for performing a disinfectant operation within an enclosed space defined by the walls, ceiling and floor of a room when a predefined condition, in the form of the absence of a human being within the room, is met. The purpose of the system is environmental decontamination and specifically to inactivate pathogenic organisms. The device includes a disinfectant module for carrying out the disinfectant operation when there is an absence of a human being within the room, and a sensing module for sensing the presence of a substantially stationary human being within the room.

Suspension cleaning

A nebuliser cup for maintaining a safe level of liquid during nebulization, the cup comprising a liquid level sensor comprising: a first element sensing liquid at or below a position corresponding to a filled liquid level in the nebuliser cup; a second element electrically isolated from the first element and located at a position corresponding to a filled liquid level in the nebuliser cup; and wherein when the cup is not filled with a liquid to the filled liquid level, the first element, the liquid and the second element do not form an electrically coupled circuit; and when the cup is filled with a liquid to the filled to liquid level, the first element, the liquid and the second element together form an electrically coupled circuit.

Liquid level sensor

A method of measuring density of a sterilant aerosol e.g. aqueous hydrogen peroxide, in a gas stream (such as a stream of air) for the purposes of measuring sterilant dosage comprising: passing a gas stream at flow rate past an electrically heated element and measuring a first cooling effect, passing an aerosol suspended in a gas stream at flow rate past an electrically heated element and measuring a second cooling effect and measuring the difference between the first cooling effect and second cooling effect and correlating the difference with aerosol density. The total dosage can thus be determined. A measured dosage of a sterilant aerosol can be delivered by way of a feedback loop to halt further delivery of sterilant aerosol when the amount of aerosol delivered reaches a predetermined dosage. The methods allow sterilization to be certified.
