DEVICE FOR ANALYSIS OF LIQUID SAMPLES.

Abstract

The present invention describes a device for analyzing liquid samples that includes a rotating base with different sections, each holding a plurality of capillaries. The liquid sample is introduced into these capillaries for analysis. Each section of the rotating base moves independently, allowing for selective control of its rotation. Another feature of the invention is an injection element, which moves vertically and horizontally via a motor and actuator, enabling it to be positioned in each of the different sections of the rotating base.The device for liquid sample analysis allows the preparation, placement of the liquid sample, application of the reagent and the performance of the analysis by means of the light emitter and receiver that are in the device and that are connected to an external processor, so the process is carried out at the same point without the need to move the sample to other positions of the device.

Description

DEVICE FOR ANALYSIS OF LIQUID SAMPLES nRfrbnn / zznz / B / γΐΛΐ TECHNICAL FIELD OF THE INVENTION The present invention relates to the technical field of mechanics, electronics, physicochemical analysis, laboratory samples and more specifically sample analysis methods, since it provides a device for liquid sample analysis. BACKGROUND OF THE INVENTION Laboratory equipment is essential in all laboratories in the scientific, industrial, and academic sectors, since without it, experiments, health monitoring, quality control, process control, etc., could not be carried out. Only with laboratory equipment are experiments, process controls, and quality controls possible. Electronic meters and vacuum gauges are among the most important tools in laboratory technology. The scientific sector of laboratory equipment would be unthinkable without them. High-quality analytical instruments, research equipment, and laboratory devices have been developed for professional use, especially for laboratory technology. User safety has been a primary consideration in the development and construction of all laboratory equipment. Where appropriate, laboratory equipment is equipped with safety buttons, safety valves, contact buttons, and thermostats. nRfrbnn / zznz / Β / γΐΛΐ A search of the state of the art of devices for liquid sample analysis was carried out, where it was found that different devices have been developed for this purpose, as mentioned in the European patent document number EP1789775 (Bl), with a publication date of June 23, 2021, which has as its title METHODS AND APPARATUS FOR DETECTING FOREIGN PARTICLES OR FAULTS IN A PLURALITY OF FILLED CONTAINERS which describes a method for detecting unwanted objects or faults in a plurality of containers that have a fluid or liquid that provides a path along which the plurality of containers is transported and moves the plurality of containers along a trajectory.The method further comprises a light source that emits light of a specific spectral distribution, the light source being placed to one side of the path, the containers being at least partially transparent or translucent to light in the specific spectral distribution, the fluid or liquid being at least partially transparent or translucent to light in the specific spectral distribution.The method also provides a camera that includes a CMOS (complementary metal semiconductor memory) electronic circuit to detect light in the specific spectral distribution emitted by the light source. The camera defines a field of view; the travel path intercepts the field of view, causing the electronic circuit to emit a digital image comprising a specific number of pixels. The camera records a sequence of digital images as the container passes between the light source and the camera. A portion of each digital image is selected—the portion that substantially corresponds to the scheme of a specific container—and each portion is transmitted to a digital image processing unit. Finally, the portion of the digital image sequence is processed to detect unwanted objects or faults in the specific container. nRfrbnn / zznz / Β / γΐΛΐ The document cited above refers to a device for detecting unwanted objects or faults using light emitters and receivers, but it does not show evidence of having a rotating base for placing containers with different sections that can rotate independently. It also does not describe a dispenser with vertical movement for placing the reagent and the liquid sample to be analyzed in each of the containers located in the different sections, nor does it mention that the operation is by means of a light source and a receiver connected to an external processor. Another document found is United States Patent Application No. US5585068 (A), dated December 17, 1996, entitled APPARATUS FOR AUTOMATICALLY SEPARATING A COMPOUND FROM A PLURALITY OF DISCRETE LIQUID SAMPLES, which describes the use of sample preparation columns that are automatically fed onto a column transport disk. The transport disk is preferably provided with composite perforations that allow the columns to be easily positioned, transported through a plurality of reagent / gas dispensing stations, and ejected after use. The previous document refers to an apparatus for separating a compound from a liquid sample, but it does not describe having a rotating base for placing samples in different sections, where each section has independent movement. It also does not detail having a dispenser with vertical movement to place the reagent and the sample to be analyzed in the different sections where the sample containers are located. Another characteristic not shown in the previous document is that the preparation, application of the reagent, and placement of the sample are carried out at the same point. nRfrbnn / zznz / Β / γΐΛ OBJECT OF THE INVENTION The present invention aims to provide a device for analyzing liquid samples, which has a rotating base with different sections for placing a plurality of capillaries in each of its sections. Another object of the present invention is to provide a device for liquid sample analysis, which allows each of the sections of the rotating base to be rotated independently. An additional object of the present invention is to provide a device for liquid sample analysis with a dispenser that has vertical movement to move between the different sections of the rotating base. Another object of the present invention is to provide a device for liquid sample analysis that allows the preparation, placement of the liquid sample, application of the reagent, and performance of the sample analysis at the same point. An additional object of the present invention is to provide a device for liquid sample analysis that has an integrated light emitter and receiver for sample analysis connected to an external processor. nRfrbnn / zznz / Β / γΐΛΐ BRIEF DESCRIPTION OF IAS FIGURES The characteristic details of this novel device for liquid sample analysis are clearly shown in the following description and accompanying figures, as well as an illustration thereof, using the same reference symbols to indicate the parts shown.

A platform (14) is installed to one side of the base (6), preferably in the direction of the lid (2); a guide (16) is installed vertically on the top of the platform (14), so that the open face of the guide (16) is in the direction of the capillary holder (7); rails (17) are located longitudinally in the middle of the inside of the front and back faces of the guide (16); slots (18) are located longitudinally inside the guide (16) parallel to the sides of the rails (17); a rack (19) is installed inside one of the slots (18). nRfrbnn / zznz / Β / γΐΛΐ A prismatic, preferably quadrangular, and hollow elevator (20) has a projection (21) on each of its lateral faces; the projections (21) are configured to install the elevator (20) inside the guide (16), assembling said projections (21) on the rails (17); a rotating element (not illustrated) is installed inside the elevator (20); a pinion (22) is installed on the rotating element (not illustrated), said pinion (22) is configured to assemble with the rack (19); the rotating element (not illustrated) is configured to transmit rotary motion to the pinion (22) and by means of the rack (19) move the elevator (20) inside the guide (16) upwards or downwards to align it with the different heights of the capillary holders (7).
