  • Publication number: 20210277440
    Abstract: A method for detecting, on a detection support, at least one microorganism present in a sample to be analysed and revealed by means of at least one cell marker includes a first taking of an image (I0, I?0) before a step of controlled release of said markerand bringing this marker into contact with said microorganism, and at least one taking of an image (Ii) following this contact step, so as to detect said microorganism according to the change in the staining kinetics thereof, by means of a comparative analysis between the different images that have been taken. An automated detection device is capable of implementing the method and a detection support is capable of being used in the method and which is part of the device.

  • Patent number: 10370634
    Abstract: The incubation and detection device includes a heater, a detection surface with at least one receptacle including a growth medium, and a detection system. There is also a system for preventing the formation of condensation in the receptacle, which includes a temperature-control formed by temperature sensors, heaters, coolers, and management device capable of collecting and analyzing the information collected by the sensor and controlling the heater and cooler so as to generate the desired incubation temperature and permanently apply a temperature gradient to the surface of the receptacle.

  • Patent number: 9732368
    Abstract: The device permitting an early detection, without measurement of the fluorescence, of colonies resulting from the multiplication of micro-organisms present in a sample to be tested, includes a substantially flat and horizontal detection surface, on which at least one support for growing the micro-organisms in the form of colonies is arranged immobile. The support is of the type membrane or agar medium. There is a detection system, such as a linear scanner, mounted movable and flat for scanning the whole or part of the surface, including at least one CCD sensor associated with an optical system comprised of at least one lighting and at least one optical device, such as a lens. The CCD sensor has a resolution higher than or equal to 2400 dpi. The detection system images colonies having a diameter smaller than 50 [mu]m through a useful magnification higher than or equal to 60.

  • Patent number: 9216262
    Abstract: The invention relates to a device for implementing a system for detecting the observance by a patient of an oxygen-therapy treatment involving an oxygen supply, and for recording the data of said treatment and transmitting said data. The invention also relates to the use of said device, and to a method for tracking the observance of an oxygen-therapy treatment.

  • Publication number: 20120103186
    Abstract: The invention relates to a method for producing gaseous oxygen by adsorption from compressed air, comprising: a) using at least one adsorption unit for generating gaseous oxygen having a purity greater than or equal to a predetermined purity threshold value (VPS) and according to a variable production flow rate (Dp); b) recovering the gaseous oxygen produced in a); c) measuring the purity of the gaseous oxygen (Pp) produced in step a) and comparing same with a preset purity threshold value (VPS); and d) adjusting the oxygen production flow rate (Dp) on the basis of the comparison of step c) such that: i) reducing the oxygen production flow rate (Dp) when the oxygen purity (Pp) measured in step c) is such that VPS>Pp; or ii) increasing the production flow rate (Dp) when the oxygen purity determined in step c) is such that VPS<Pp in order to obtain a gaseous oxygen purity (Pp) such that VPS=Pp+X, with X<0.5%, X being the standard deviation.

  • Publication number: 20120073680
    Abstract: The invention relates to a safety device constituting a valve for releasing pressurized gas in the event of a dangerous situation, including a body defining a gas flow channel extending in a longitudinal direction between a first upstream end to be brought into contact with a pressurized gas source (G) and a second downstream end to be brought into contact with the outer atmosphere, wherein the device includes a plug located in the channel for preventing the flow of gas between the upstream end and the downstream end in a normal situation, the plug being shaped so as to release the passage for the gas in the event of a dangerous situation in which it is subjected to a pressure and/or a temperature exceeding a predetermined threshold, characterized in that, from the upstream direction toward downstream direction, the channel includes two upstream and downstream adjacent flow portions, respectively, having different respective transverse dimensions (d, D), the ratio D/d between the transverse dimension D of the
