20150300937 | Apparatus and Method to Determine the Blood Sedimentation Rate and Other Parameters Connected Thereto - An apparatus to determine the blood sedimentation rate and other parameters connected thereto, carried out by emitting, by means of emitter means, a beam of radiations which passes through a sample being examined, and by detecting, by means of receiver means, the beam of radiations after they have passed through said sample, comprising a reading chamber associated to at least a tube connected to a feed of the sample to be analyzed. Said reading chamber is at least partly transparent to radiations in a certain range of wavelengths, and has at least a substantially rectilinear segment of reduced size into which the sample to be analyzed is introduced. The reading chamber consists of a tube made of plastic material, or glass, defining a capillary channel coupled to said tube in fluidic continuity. | 10-22-2015 |
20130022962 | METHOD AND APPARATUS FOR DIAGNOSTIC ANALYSES - A method for diagnostic analyses, in particular to identify pathogens, such as viruses, bacteria or other micro-organisms present in a biological sample, comprises a first step of measuring and continuously monitoring the turbidity and/or the concentration of the pathogens, by means of an instrumental reading technique, of a liquid culture medium into which the sample to be analyzed has been inoculated and in which the replication of the pathogens possibly present occurs, said measuring and monitoring being carried out dynamically during the replication of the pathogens growing in the culture medium; and a second step of identifying the pathogens, carried out by taking at least an aliquot of the liquid culture medium containing the biological sample directly obtained from the first step, which has reached a desired value of turbidity according to a standardized value scale, such as the McFarland turbidity scale, and/or of concentration of the pathogens, and using said aliquot directly in mass spectrophotometric identification means ( | 01-24-2013 |

20110307183 | METHOD FOR THE BACTERIOLOGICAL INVESTIGATION OF A BIOLOGICAL SAMPLE AND RELATIVE DEVICE - A method for the bacterial investigation of a biological sample, which provides to carry out a light scattering reading in order to determine the turbidity according to the McFarland standard of a suspension formed from a liquid culture means or eugonic medium in which the biological sample is inoculated, and in which the turbidity is continuously measured directly from the suspension of the sample analyzed during the growth step of the bacteria, until a determined threshold of turbidity is reached expressed according to the McFarland standard. | 12-15-2011 |
20110306087 | APPARATUS TO ANALYZE A BIOLOGICAL SAMPLE - An apparatus to analyze a biological sample contained in a container, comprising an examining device able to perform an optical measurement on the biological sample, based on light-scattering technology, at least of the bacterial growth in the biological sample. The examining device is provided with emitter means able to emit a first light beam toward the container of the biological sample and sensor means able to detect at least a light beam diffused from the container of the biological sample and to transmit a relative signal, correlated to the light beam diffused, to a control unit which is able to process, directly or indirectly, the signal in order to verify at least the possible bacterial growth in the biological sample. The container is disposed along a determinate lying plane and comprises at least a containing micro-element able to contain at least a part of the biological sample and inside which a liquid culture ground is provided so as to allow bacterial growth in the biological sample. The emitter means and sensor means are able to be located on each occasion in correspondence with the containing micro-element. The sensor means comprise first sensor means disposed on the same side of the emitter means with respect to the lying plane, and second sensor means disposed on the opposite side of the emitter means with respect to the lying plane. The first sensor means are able to detect a back-scattering radiation coming from the determinate containing micro-element. The second sensor means are able to detect a forward-scattering radiation coming from the determinate containing micro-element, from which back-scattering radiation and forward-scattering radiation derive respective first and second signals transmitted to the control unit. | 12-15-2011 |
