Definitions
- the present invention relates to a reaction amplification device intended to duplicate a large number of a DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) sequence to detect bacteria, viruses or any other genetic element present in a sample.
- This device lends itself easily to in vitro analyzes such as PCR (Polymerase Chain Reaction), RT-PCR, qPCR, RT-qPCR, LAMP (Loop-mediated isothermal amplification) or RT-Lamp used in particular in the context of screening tests of Covid-19.
- the device according to the invention is disposable and configured to receive a sample of saliva, nasal or buccal swab in, at least, a first compartment containing at least one component used to process the sample.
- the device comprises, at least, a second compartment comprising, at least, a reagent intended for amplification of the PCR, LAMP, RT-PCRRT-LAMP type which is designed so as to be able to receive all or part of the contents of the first compartment at the through a channel having a movable closing and opening mechanism.
- the device is associated with an apparatus comprising in particular at least one thermoregulated element intended to modify the temperature of the first compartment and at least one second thermoregulated element intended to modify the temperature of the second compartment.
- the present invention also relates to a method for implementing the amplification device as well as to a luminescence or fluorescence detector intended to operate with the device.
- PCR or LAMP amplification systems and methods which are based on the transfer of fluid by pipetting or pumping the sample to be analyzed into tubes to operate different purification steps before being transferred into a tube containing the reagent for amplification.
- the preparation time requires many manipulations which slow down the processing of the samples.
- the final step involves heating the reaction tube into which an aliquot of the purified sample is transferred by pipetting or pumping. During the reaction, it is necessary to close the tube in order to avoid the dissemination in the air of the contents that could contaminate operating personnel and the environment, potentially rendering the amplification process hazardous, inefficient and polluting.
- SARS-CoV-2 (Covid-19) in particular in a simplified way such as the "Visby Medical COVID-19 Test” reader which is a disposable system allowing a result to be obtained in 30 minutes based on the patent US20160186240A1.
- This system remains intended for qualified personnel because it also requires the handling of the sample and the transfer of an aliquot with a pipette into the test compartment.
- This system is also difficult to recycle and comprises many non-disposable components, which poses environmental problems and cannot in any case be used on a large scale.
- a main object of the present invention is therefore to propose a device for the amplification of DNA / RNA at low cost by an automatic transfer of the sample collected directly towards the reagent intended for the amplification in a safe manner and without external intervention which overcomes the drawbacks of the prior art allowing it to be used also by the general public.
- a second object of the present invention consists in being able to carry out the PCR or LAMP amplification in a closed compartment avoiding any external contamination and health risk.
- the present invention relates more particularly to a DNA/RNA amplification device, of the type mentioned above, characterized in that the transfer part of the sample collected and treated towards the amplification reagent is activated by a mobile element.
- the present invention also relates to a preferably portable apparatus intended to receive the DNA or RNA amplification device, of the type mentioned above, characterized in that it comprises at least one thermoregulated element.
- the DNA or RNA amplification device allows the detection of a virus present in a sample directly by the user without the intervention of an external person, without risk and at very low cost. It is thus possible to test a very large part of the population in the context of an epidemic such as that of Covid-19 with very high precision while detecting asymptomatic and symptomatic people.
- the device in combination with a suitable reader can be produced in large quantities due to its simplified design.
- the DNA or RNA amplification device can also be integrated into laboratory or mobile test devices that can perform tests in parallel in order to increase the test capacity.
- the reader devices associated with this DNA or RNA amplification device are preferably equipped with a network or wireless communication system so as to be able to communicate the operating parameters, receive commands, transfer data between them and/or with devices devices such as phones, tablets, PCs or across the Internet to servers. It is thus possible to create an interconnected test network making it possible to process data on a large scale, produce statistical reports in real time, create detailed analysis reports via "Cloud” type services, facilitate the detection of outbreaks of infection and communicate to patients the instructions to follow for their treatment or containment.
- the present invention further relates to a method for implementing the DNA or RNA amplification device comprising in particular the following steps: i. open the device containing a solution, ii. add a sample to be analyzed into the collection compartment, iii. adding an ingredient to the collection compartment, iv.
