AUTOMATED ENDOSCOPE REPROCESSOR Russian patent published in 2013 - IPC A61L2/18 A61B1/12 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medical equipment, to sterilisation of medical devices. A processor for medical devices, particularly endoscopes, comprises a device fixation chamber, a liquid distribution system for delivering a liquid containing a sterilant to the device, a sterilant (e.g. ortho-phthalaldehyde) concentration measurement subsystem. The above subsystem comprises a bubble filter coupled with the liquid distribution system, a sample chamber with transparent walls coupled to a sample outlet of the bubble filter, a light source, a light sensor, a control system for measuring the sterilant concentration in the sample based on the light supplied to the sensor. The bubble filter comprises a cross flow filter. A liquid flow is directed through the bubble filter. The liquid sample is directed to the sample chamber. The light of specific intensity and wave length is provided to pass through the liquid sample in the sample chamber. The light having passed through the chamber and the sample therein is detected by means of the sensor, and the sterilant concentration in the sample is measured. The liquid flow passes along the membrane and a portion of the fluid passes through the membrane while providing the sample and thereby preventing the bubble collection in front of the membrane.

EFFECT: use of the group of inventions enables higher accuracy of the sterilant concentration measurement in the processor for various medical devices.
