    (54) DEVICE FOR MONITORING A BIOLOGICAL SAMPLE, PARTICULARLY FOR A LABORATORY ANALYSIS.
    The present invention relates to a device for monitoring a biological sample. Typically it includes:
    - at least one receptacle for receiving at least one biological sample associated with a writable chip,
    a control unit with manual triggering means and first transmission means allowing the recording of data relating to the sample following a triggering,
    a container for storing and transporting said at least one receptacle, comprising a temperature sensor, second transmission means allowing the recording, in the chip associated with each receptacle, of measurements of temperatures at programmable time intervals,
    - a central unit with data processing means capable of controlling the quality of a sample of a receptacle as a function of the temperature and / or time data entered in the associated chip.
    TECHNICAL FIELD OF THE INVENTION
    The present invention relates to a device for monitoring a biological sample, in particular for laboratory analysis.
    PRIOR ART OF THE INVENTION
    When the healthcare professional takes a sample from the patient's home, significant logistical and traceability problems arise to preserve the quality of the sample. Indeed, the health professional cannot go, after each sample taken, directly to the medical analysis laboratory or pharmacy to deliver the sample for analysis and the sample undergoes uncontrolled temperature variations which may affect its quality.
    In practice, the healthcare professional must note his schedule for each sample and take into account the urgency for delivery to the laboratory or pharmacy. This operation is tedious and also insufficient because the degradation of the sample is also due to the temperatures undergone by the sample which are not recorded by the professional.
    To date, taking into account the vagaries linked to the travel time, the distance to the laboratory being sometimes important, and especially to the conditions of transport of the samples thermally, it is not possible to precisely assess the quality of the sample arrived at the laboratory.
    On the medical level, this poses an important problem since a degraded sample does not allow a satisfactory analysis which can be used by the doctor to be able to make a diagnosis or modify the treatment, for example.
    From a regulatory standpoint, the regulations in force are placing increasing responsibility on laboratories with a view to increasing the quality of analyzes and ultimately patient safety. The laboratories that have to analyze the samples carried out at home therefore engage their responsibility without mastering the entire supply chain. To limit the risk of error in analysis, laboratories are forced to increase the sample rejection rate, and in particular as soon as there is any doubt about compliance with the sampling chain in terms of temperatures experienced and / or on the time between sample collection and analysis. Each refusal requires a repeat sample, which is problematic both economically and medically in the sense that the diagnosis based on the analysis of the sample taken is necessarily deferred.
    TECHNICAL PROBLEM TO BE SOLVED
    A first aim of the present invention is to solve all or part of the technical problems linked to the above-mentioned prior art.
    Another object of the present invention is to improve the control of the sampling chain, upstream of the laboratory analysis.
    Another object of the present invention is to allow the traceability of the samples upstream of the laboratory analysis.
    Another object of the present invention is to propose a system for monitoring a biological sample making it possible to improve the biological analysis of the samples and to decrease the rate of refusal of samples.
    Another object of the present invention is to provide a reliable and easy recording system for the healthcare professional ensuring the sample.

    DEFINITIONS
    The term "sample" refers to any biological material from the organism of a living being; it can be a fluid or a piece of cloth. The fluid can be a fluid excreted naturally by the body or be taken from it. The sample can be, for example, urine, blood, a biopsy tissue sample, stool. The term "sample" can include both biological material and the first container containing this biological material.
    DETAILED DESCRIPTION OF THE INVENTION
    With reference to FIG. 1, a particular embodiment of the device of the invention will now be described. According to this embodiment, the device 1 comprises a control unit 2, a remotely rewritable chip 3 secured to a receptacle 4, the latter allowing the reception of biological samples, the control unit 2 comprising first transmission means 5 These samples are advantageously in the form of a plurality of tubes containing blood while the receptacle 4 is in the form of a pouch.
    The device 1 also comprises a container 6 advantageously in the form of an insulated bag, this container 6 is equipped with a temperature sensor 12 and second transmission means 7, arranged in said container 6.
    Referring to Figures 2 and 3 we see that the device 1 further comprises a central unit 8 with in particular processing means 9, these processing means 9 can be at least partially offset in the container 6 or in the control unit 2 allowing certain processing operations to be carried out locally or remotely. This central unit 8 is preferably installed in the medical analysis laboratory
    The control unit 2 includes manual trigger means 10 with a push button 11, pressing the button 11 activates the recording of the date and time on the chip 3.
    In a variant not shown of this particular embodiment, the control unit 2 comprises a second push button, pressing this second button to write on the chip 3 the fact that the sample must be analyzed urgently.
    In another variant, not shown, which can be combined with the aforementioned variant, the control unit 2 is coupled to a temperature sensor which measures the ambient temperature. In general, if we consider that the sample taken will be very quickly introduced into the container, this measurement of the ambient temperature is not necessary. However, recording the room temperature during sampling can also be useful for subsequent biological analysis of the sample.
    The manual triggering means 10 activate the first transmission means 5 so as to write on the chip 3, the time of sampling, and also other types of information and in particular the ambient temperature measured by the temperature sensor the date or the name or code of the professional who took the sample when the control unit 2 is linked to the latter.
    In an alternative embodiment, the box 2 includes writing means for writing on said chip 3 at least one parameter chosen from the name of the person who carried out said sampling, the urgency of said sample, the type of sample or even the conditions of withdrawal. These means of registration can constitute a keyboard or even a voice command. To this end, the control unit 2 is advantageously produced by a portable telephone equipped with RFID or NFC technology or any other radiofrequency electronic device equipped with a keyboard or a voice command.
    It is thus possible to also write in the chip 3 particular information such as the respect of the conditions of sampling by the patient, and for example indicate the respect of a fast, of a previous medication, of a good hydration or conditions specific to his treatment or indicate the patient's condition and in particular indicate fever or flu-like conditions that can modify the analysis to be performed, these data can be very important during the analysis.
    With reference to FIG. 2, an operating mode of a first particular embodiment of the monitoring device 1 according to the invention will now be described.
    Step 1A is the collection of the biological sample. In this case, it is a blood test. The tubes filled with blood forming the biological sample are enclosed in a pouch, acting as receptacle 4, on which the chip 3 is stuck.
    In step 1B, the nurse starts using the control unit 2 the recording on the chip 3 of the date of the sample and the time of the sample. It may also, if necessary also record the fact that the sample must be analyzed urgently and / or the type of sample (urine, blood, biopsy or other). It can also record the measurement of the ambient temperature if the control unit 2 is coupled to a temperature sensor.
    During step 1 C, the sample 2 provided with the chip 3 is inserted into the insulated bag 6 acting as a container 6. The second transmission means 7 are configured to register at predetermined intervals, for example every 5 minutes, the temperature measured in the insulated bag 5 by the temperature sensor 12.
    In this case, the second transmission means 7 write on the chip 3, every 5 minutes the time and the temperature in the insulated bag 6.
    In step 1 D, the healthcare professional transports the sample 2 contained in the cooler bag 6, either directly to the analysis laboratory, or by passing to other patients to take other samples. During this step the second transmission means 7 write the same information on the chip 3, that is to say the time and the temperature measured at said time by the temperature sensor 12. If the bag 6 contains several samples comprising each a chip 3, the inscription is done on each of the chips 3.
    Step 1E is the delivery to the laboratory of the sample 2. Each receptacle 6 is taken care of in the laboratory.
    The central unit 8 is equipped with reading means 13, such as a chip reader, adapted from the information contained in said chip 3. The processing means 9 make it possible to process the data of the chip 3, advantageously these processing means 9 further include a display for displaying the temperature curve of the sample as a function of time.
    Referring to FIG. 3, an example of the representation of this curve is shown for a chip 3.
    The processing means 9 in addition to processing the data from the chip 3 to display them can also assign a level of quality to a sample according to the data on the chip and the type of analysis to be carried out on this sample, for this purpose the processing means include a database. For example, the database will include different maximum temperature thresholds for the validity of the sample according to the type of analysis and for example according to a urine analysis or a blood analysis. For example, the database will include maximum transport time thresholds before analysis depending on the type of analysis to be performed.
    According to an advantageous aspect of the invention, the processing means 9 and the database make it possible to link the data of the chip and / or of each sample with the data of the patient.
    Referring to Figure 4 there is shown an alternative embodiment in which the monitoring device 1 further comprises a central container 14, in the form of a terminal. This terminal 14 constitutes a deposit point for the receptacles 4 and comprises means of access control. Access control makes it possible both to control the deposit by the professionals who carried out the sampling and also to allow the recovery of samples by a person accredited by the laboratory.
    The advantage of such a terminal and of creating a drop-off point for professionals, making it possible to reduce the length of trips by not requiring them to go each time to the laboratory.
    Advantageously, this central container 14 comprises in addition to the technical characteristics of the containers 5, such as the remote processing means, the second transmission means and a temperature sensor, various additional characteristics and in particular secure access means, means of autonomous energy operation or means of alert. Note that these alert means can also be present in an alternative embodiment in the containers 6.
    Referring to fig. 4 it can be seen that the monitoring device in this second embodiment is very close to that of FIG. 2, apart from the fact that the samples are not delivered by the health personnel having taken the sample in the laboratory but inserted by the latter in the central container 14. Step 1F is therefore different from that concerning the use of the first embodiment of the monitoring device 1 of the invention.
    When the samples 2 are introduced into the central container 14, the latter records, in particular via the second transmission means, the temperature and the time on the chips 3 of each of the samples (step 1G). In the same way, the temperature is measured, for example every 5 minutes
    During step 1H, the laboratory personnel collect the samples contained in the central container 14 and place them in a container 6 (which can also be the insulated trunk of a vehicle) which in turn records the data, in particular temperature , in chips 3. He then transports this tray to the laboratory. Step 11 is the laboratory processing step. It is identical to that described with reference to FIG. 2.
    Fig. 3 represents an example of display on the screen of the remote central unit 9 of the data written in the chip 3 and processed by the processing means 9. The time range 2A corresponds to the duration of storage of the sample in the container 6 in the form of an insulated bag 6; the time range 2B corresponds to the duration of storage of the sample in the central container 14. The time range 2C corresponds to the duration of storage in the container 6 in the form of an insulated container, during the transport of the samples in the container 6 of the laboratory.
    The 2D curve represents the temperature as a function of time, measured by the various temperature sensors. The remote central unit 8 can also display the maximum temperature measured by the sensors, the total storage time, the minimum temperature recorded on the chip, the name of the nurse and / or of the patient if these have been recorded on the chip or the reference of the containers 6.
    The monitoring device 1 as described thus allows complete traceability of the storage temperatures of the receptacles 4 containing the samples from the taking of these samples and until their analyzes.
    Of course, other characteristics of the invention could also have been envisaged without departing from the scope of the invention defined by the claims below.
    By way of example, according to an alternative embodiment, the container includes alert, visual or audible means which are coupled to the second temperature sensor and which make it possible to alert the healthcare professional when the temperature measured in the second container is greater than a pre-stored given value.
    According to an alternative embodiment, the container further comprises means for inscribing on said chip an element indicating the entry of said sample into said storage area. It is thus easier to determine the start of storage of the sample in the collection device. In the case of the central container or terminal, these means can, for example, cooperate with the access opening mechanism inside the storage area.
