Description

DESCRIPTION

Method and system for the surveillance of a person who requires supervision before at least one potentially dangerous product, preferably a drug and/or medicine

Technical sector of the invention

The method and system of the present invention allows monitoring a person who requires supervision to avoid contact with one or more potentially dangerous products, such as chemicals or drugs.

Background of the invention

Currently, most medications and/or any type of product considered dangerous, toxic, corrosive, irritant, chemical, etc. they are a problem when they are within reach and can be manipulated and even ingested unduly, accidentally and/or unconsciously by a population at risk.

When we refer to a population at risk, it is, ultimately, the entire population of a country-territory, but we are especially referring to people who, due to their age, physical condition and vulnerability, require care and surveillance, such as babies, children, elderly people, people with any type of disability, dependent people, people with neurological diseases and others.

Warning messages and notes incorporated in the same containers and/or packaging of medicines and products considered dangerous to health warn and/or warn to establish a safety distance and not to keep medicines within the reach of children, innumerable means whether they are public and/or private televisions, radio stations, press, official national health agencies, official international health agencies (World Health Organization-WHO) and other bodies of all kinds, especially health, have and In fact, they show great sensitivity and support this issue in articles and periodic informative publications of all kinds, issuing messages, press releases, announcements and communications in these media with the aim and purpose of trying to convey to the population in general the precaution, recommendations , and the sensitivity and care that must be taken especially with children and all kinds of people d ependants with this type of dangerous health products and especially with medicines, and all this due to the millions of poisoning and hundreds of thousands of deaths worldwide that occur each year due to its handling and/or ingestion. Notwithstanding and despite this collective effort, the fact that many serious domestic accidents continue to occur daily due to these circumstances cannot be avoided, unfortunately often resulting in death in the homes of these children and dependents. (population at risk), on many occasions these groups are also located in kindergartens, nurseries and schools, the first and in innumerable care centers, shelters and residences for the elderly of all kinds, the second.

It is therefore an objective of the present invention to disclose a procedure and system for the surveillance of a person who requires supervision in the face of at least one potentially dangerous product, preferably a drug, which allows for satisfactory control, prevention, warning and control. protection, so that it helps this population at risk in particular (who are ultimately dependent people in all cases) to be controlled and protected at all times by their guardians or caregivers wherever they are, whether they are professionals or not, in order to preserve your health and/or on many occasions your life.

Explanation of the invention

The method of the present invention for the surveillance of a person who requires supervision before at least one potentially dangerous product, in which the potentially dangerous product is preferably a medicine, is essentially characterized in that it comprises the sequence of steps of issuing by some signaling means located on the potentially dangerous product a radioelectric signal comprising an identification of the product and/or the composition of the product; detecting by portable detection means located on the person requiring supervision the radioelectric signal emitted by the signaling means when the portable detection means and the signaling means of the potentially dangerous product are less than a predetermined threshold distance from each other; extracting the identification of the product and/or the composition of the product from the radio signal and triggering a warning of the approach between the person and the potentially dangerous product from the identification of the product and/or the composition of the product extracted.

Advantageously, by means of this method an effective control of the people who require supervision is achieved, so that their tutors or caregivers can receive an alert when these people approach products considered dangerous. Thus, the media signaling will transmit a radioelectric signal of a previously predetermined type and format and adapted for reception by the portable detection means, in which the identification will be encoded, for example, in a known modulation and that the portable detection means will be prepared to detect, demodulate and decode. These portable detection means can be made up of and comprise a nanochip, a subcutaneous microchip and/or an identification microchip located in the person considered to be the risk population to be controlled. The portable detection means may also comprise an FSK modulator (frequency shift modulator), a radio frequency amplifier and a demodulator composed of a high-pass filter and an envelope detector followed by a voltage level changer. Naturally, the portable detection means will in turn be provided with one or more processor and memory assemblies, adapted to execute software for managing the reception and processing of the radioelectric signals received from the signaling means to trigger a warning of the approach between the person and the potentially dangerous product based on the identification of the product and/or the composition of the extracted product, which can be carried out in the portable detection means or in other devices of the system as configured.

In a variant embodiment, the step of extracting the identification of the product and/or the composition of the product from the detected radioelectric signal is carried out in the portable detection means, thus allowing the portable detection means carried by the person and which are provided with the necessary electronics for the reception and processing of the radioelectric signal, and for extraction of the identification, the portable detection means being able to generate an alarm signal or send an alert to other devices. These portable detection means may be of any type, in the form of a bracelet, a pendant or even a consumer electronics device such as a smartphone, a smart watch or a tablet that runs a computer application that allows it to detect the radioelectric signal. and process it conveniently in order to trigger a warning.

For example, in an embodiment variant, the step of triggering a warning of the approach between the person and the potentially dangerous product comprises notifying the portable detection means to a monitoring device of the approach between the person and the potentially dangerous product, so that the surveillance device generates an alarm signal of approach between the person requiring supervision and the potentially dangerous product. In this way, the portable detection means will be adapted to send to a monitoring device, which may be for example located in a guardian and/or caregiver of the person requiring supervision, or in their environment, in such a way that it can alert the guardian and/or caregiver of the approach of the person requiring supervision to the product considered dangerous and provided with the signaling means, so that they can warn that the person who requires supervision could be in danger in a few seconds if urgent and rapid action is not taken, for example based on a previously established protocol. Within the scope of the invention, it is considered that the caregiver can be a professional, such as a nursing professional, a professional caregiver or an operator of an alarm center, but can also be a person close to the person who requires supervision, for example, with a degree of kinship the person who requires supervision, such as parents or children.

In a variant embodiment, the signaling means are located in a container and/or packaging that contains the potentially dangerous product. These can be, for example, a radio frequency card, RFID tag attached to the container and/or packaging or any other device known in the state of the art, such as NFC, zigbee or bluetooth devices, which allow the emission of a radioelectric signal. that incorporates a unique identification, as a beacon. It is naturally also provided that the signaling means are arranged in the immediate vicinity of the product. It is contemplated that the emission frequencies of the signaling means may be in the VHF, UHF or even EHF radio bands.

These signaling means can be formed, for example, by an RFID chip previously pre-encoded or pre-recorded by the manufacturers in the container and/or packaging of any type of drug and/or medication, product and/or chemical element considered dangerous to health and/or or the life of people and/or human beings.

In a variant embodiment, the method further comprises the step of obtaining and submitting a previously established emergency action protocol associated with the product and/or the composition of the product to be carried out in the event of contact of the person requiring supervision and the product considered dangerous based on the identification of the product and/or the composition of the product. It is expected that this emergency action protocol can be presented on a screen of the surveillance device. This emergency action protocol can be stored in the surveillance device itself, for example, in a local database, so that from the identification of the previously obtained product, the emergency action protocol can be extracted. show and what the caregiver should do to the person requiring supervision if they come into contact with the product. This local database, which can be consulted without connection to a network, such as the Internet, can be a copy of a remote database that, whenever possible, is updated. It is also foreseen that the database is remote and each time a request is made to the remote database, for example, based on identification.

In a variant embodiment, the signaling means of the potentially dangerous product emit the radioelectric signal that includes the identification of the product and/or the composition of the product when the signaling means receive a radioelectric power signal emitted by the portable detection means, thus being energized by proximity and not requiring its own dedicated power supply.

In a variant embodiment, the threshold distance is equal to or less than 10 meters, in order to ensure that the radioelectric signal is detected by the portable detection means sufficiently in advance and before manipulation or contact can occur and subsequently possible ingestion of the content of the product considered dangerous, such as a drug, medicine, or chemical element considered dangerous.

Preferably, the threshold distance is equal to or less than 1.5 meters, this being considered as a risk distance below which the operation of the alarm system will necessarily be activated. Advantageously, when the signaling means are RFID technology labels, the maximum transmission distance is already established at approximately 1.5 meters, so it would be a sufficient threshold distance to trigger a warning sufficiently in advance of the person requiring supervision. come into contact with the product considered dangerous.

In a variant embodiment, the step of triggering a warning of the approach between the person and the potentially dangerous product comprises making an emergency telephone call.

In a variant embodiment, the method further comprises the sequence of steps of detecting by the portable detection means, simultaneously with the first radioelectric signal, a second radioelectric signal that includes a second identification of a second product and/or composition of the second product; determine if there is an interaction hazard relationship between the first product and/or product composition and the second product and/or second product composition from the first identification and the second identification detected, in the event that the products and/or the composition of the products may produce dangerous interactions, preferably pharmacological interactions, more preferably pharmacological incompatibilities; and triggering an additional warning of the approach between the person, the product and the second product. A pharmacological incompatibility is considered an undesirable reaction between drugs and between drugs and a diluting solution; and drug interaction as when the action of one drug is modified by another drug. For example, dangerous interactions can occur with benzodiazepines administered together with antihistamines; corticosteroids given together with medicines to treat epilepsy; antibiotics given together with anticoagulants; and antihistamines given together with bactericidal antibiotics. It is also considered that a drug is a simple active ingredient, while a drug is the result of combining one or more mixed drugs, in addition to other substances, which despite not being active ingredients help the drug fulfill its function. in the organism.

A system for monitoring a person who requires supervision in the face of at least one potentially dangerous product, preferably a drug, is also disclosed, the system comprising signaling means located on the potentially dangerous product adapted to emit a radioelectric signal comprising a identification of the product and/or the composition of the product; portable detection means suitable for being placed on the person requiring supervision and adapted to detect the radio signal emitted by the signaling means when the portable detection means and the potentially dangerous product signaling means are less than a predetermined threshold distance, the portable detection means being further adapted to trigger a warning of the approach between the person and the potentially dangerous product based on the identification of the product and/or the composition of the product extracted from the radioelectric signal.

In a variant embodiment, the portable detection means are adapted to extract the identification of the product and/or the composition of the product from the detected radioelectric signal.

In a variant embodiment, the system further comprises a surveillance device adapted to receive a notification from the portable detection means, the surveillance device being adapted to trigger a warning by generating a warning signal. alarm to warn of the approach between the person requiring supervision and the potentially dangerous product.

In a variant embodiment, the monitoring device is provided with display means, adapted to display a protocol of action to be carried out in the event of contact between the person requiring supervision and the product considered dangerous.

In a variant embodiment, the surveillance device is provided with a button to make an emergency telephone call, for example, to a preconfigured telephone number, such as 112, so that a caregiver can quickly communicate with emergency services. emergency by simply pressing the button.

In a variant embodiment, the signaling means are located in a container and/or packaging that contains the product, so that they act as a beacon for the product.

In a variant embodiment, the signaling means comprise an RFID tag. Specifically, in a variant of interest, the signaling means comprise an adhesive RFID label. It is further envisaged that signaling means can be obtained individually or in groups, for example, pre-recorded RFID tags with known identifications, as a kit, so that a user can incorporate these labels or other means of signaling in dangerous products, those you want the person requiring supervision to be away from.

It is envisaged that, in a variant embodiment, the portable detection means, optionally in combination with a surveillance device, can be used to carry out a sweep through different regions of a room in search of high-cost drugs (for example, prescription drugs). oral chemotherapy) that have been lost and that have signaling means incorporated, turning the surveillance device with this functionality into a search device. Thus, the portable detection means will trigger the warning when approaching the lost medication provided with the signaling means, allowing its location and recovery.

Detailed description of the drawings

Fig. 1 presents an example of a product 3, which in this case is a medicament, prepared to form part of the system 1 and used in the method according to the present invention. As can be seen, the product 3 is provided with signaling means 4 located in a container and/or packaging 12 containing the potentially dangerous product 3. In Fig. 1, these signaling means 4 are an adhesive RFID-type radiofrequency label that is configured to emit a radioelectric signal 5 that includes an identification 6. It is expected that this identification 6, duly encoded in the radioelectric signal 5, allows identifying product 3 and/or composition of product 3. Thus, identification 6 may allow, as will be presented later, to identify product 3 itself, such as "ZAMENE" and "LYRICA" or its compositions such as "DEFLAZACORT" and "PREGABALINA". In this way, the means of signaling 4 with the same identification 6 of product 3 could be used in products 3 of the same type, and the means of signaling 4 with the same identification 6 of product composition 3 could be used in products that, although they are different, they incorporate the same ingredient in their composition.

For this purpose, as shown in Fig. 2, it is envisaged that this identification 6, which can be for example a unique serial number, has been associated in a database 15 with the details of the product 3 or of the composition of the product 3, for example, its name and with an emergency action protocol 13, as well as a list of danger due to pharmacological interaction 14 and/or pharmacological incompatibility with other products and/or product compositions. In this way, through the database 15, it will be possible to obtain, by means of an identification 6, the protocol 13 for emergency action, which will be, for example, a set of steps to be carried out in the event of contact between a person 2 and the product 3. It is important to be able to know these steps to be able to act correctly in case of contact of a person 2 with the product 3, for example, if it comes into contact with the skin of a person 2 or is even ingested by a person 2. In addition, it is expected that in the database 15 identification 6 is also related to identifications 6 of other products or other product compositions that could produce dangerous interactions, for example, drug interactions, as well as drug incompatibilities. In this way, if the identification 6 of the product, for example a medicine or a component of the medicine, has previously been associated in the database 15 with its emergency action protocol 13, from the identification 6 of the product that during the use of the product 3 can be extracted from the signaling means 4 can be accessed through the database 15 to its protocol 13 for emergency action, as well as possible dangerous interactions with other products, for example drug interactions such as incompatibilities. This database 15, in which the identifications 6 of the different products 3 or compositions of products 3 will be registered, and their related information can be, for example, a relational database of those known in the state of the art, and available for its remote access on a server, accessible for example via the internet. It is also expected that the database 15 can be located locally, allowing faster access to information. Said emergency protocol 13 will establish, for example, carrying out first aid carried out based on product 3 or its composition, for example in the event of ingestion if it is a drug and/or

1

medicine, and that are necessary to stabilize the person 2 to control, if possible. Naturally, it is anticipated that this protocol 13 and the first aid to be performed will have been previously approved, supervised, clinically validated and authorized by the corresponding health authorities. In this way, it is anticipated that the database 15 may be in the hands of authorized bodies, thus standardizing the identifications 6 for the different products 3 that manufacturers must incorporate into the signaling means 4 of their products 3, for example, in drugs and/or medications.

Although it is expected that the signaling means 4 incorporate their associated identification 6 by factory, it is also foreseen that there may be signaling means 4 on which it is possible to configure and write its identification 6, for example if the signaling means 4 are RFID tags writable by means of an RFID label writing device, which in turn allows, if possible, to register the identification 6 in a database 15 and associate it with an emergency action protocol 13 and with identifications 6 of other products 3 or compositions of products 3 with which there could be dangerous interactions. Naturally, it is envisaged that the same signaling means 4 can incorporate more than one identification 6, for example by encoding them serially in the radioelectric signal 5, these identifications 6 being able to be of various components of the product 3, if necessary.

Fig. 3a presents a system 1 according to the present invention, for carrying out a method for monitoring a person 2 who requires supervision for at least one potentially dangerous product 3, preferably a drug and/or medication. The system 1 comprises signaling means 4 located in the potentially dangerous product 3 and adapted to emit a radioelectric signal 5 comprising an identification 6 of the product 3 and/or the composition of the product 3 and portable detection means 7 suitable for be placed on the person 2 requiring supervision and adapted to detect the radio signal 5 emitted by the signaling means 4 when the portable detection means 7 and the signaling means 4 of the potentially dangerous product 3 are within less than one predetermined threshold distance 8, the portable detection means 7 being further adapted to trigger a warning of the approach between the person 2 and the potentially dangerous product 3 based on the identification 6 of the product 3 and/or the composition of the product 3 extracted from the radioelectric signal 5. These portable detection means 7 are adapted to extract the identifi cation 6 of the product 3 and/or of the composition of the product 3 of the radioelectric signal 5 detected.

This Fig. 3a represents a situation prior to the approach of a person 2 who has portable detection means 7 located to a potentially dangerous product 3 provided with signaling means 4. In the embodiment presented, the portable detection means 7 that it can be an electronic device, provided with conveniently programmed memory and processor sets and connected to one or more antennas, mounted on a bracelet, allowing the portable detection means 7 to be correctly located on the person 2 and to be able to move together with the person 2 in order to be able to determine the position of the person 2 and detect, by means of an antenna, radioelectric signals 5 from the signaling means 4. In this way, the portable detection means 7 will allow determining the approach of the person 2 who requires supervision to the dangerous products 3 that will be provided with means of signaling 4 and whose identification 6 will have been deb previously configured in a database 15.

It is envisaged that the portable detection means 7 comprise an antenna, one of those known in the state of the art, and that it is adapted to emit a power radioelectric signal 11 that allows the signaling means 4 that are in its range to be energized, for example when these signaling means 4 are passive and require external energy radiation to be able to emit their corresponding radioelectric signal 5 containing their identification 6. Naturally, the portable detection means 7 may not need to radiate a power radioelectric signal 11 if For example, in the environment, all the signaling means 4 are of the active type, that is, they are provided with their own power means, for example batteries, such as for example a zigbee or bluetooth device.

The range of the radioelectric signal 5 of the signaling means 4, as well as the sensitivity threshold configured in the portable detection means 7 for the reception of the radioelectric signal 5 will determine a predetermined threshold distance 8, so that if the detection means portable detection means 7 and the signaling means 4 are less than this threshold distance 8 from each other, the portable detection means 7 detecting the radioelectric signal 5, and consequently the identification 6 of the product 3 or of the composition of the product 3 , they will determine that the person 2 and the potentially dangerous product 3 are close to each other, being able to trigger a warning to warn of this proximity. This threshold distance 8 could be, for example, equal to or less than 10 meters, for example, if the signaling means 4 are active, or equal to or less than 1.5 meters if, for example, example the signaling means 4 are passive. Although it is expected that in the same environment all the signaling means 4 are either active or passive, in order to have the same threshold distance 8 after adjusting the sensitivity of the portable detection means 7, it is also planned to be able to combine signaling means 4 active and passive, so that different threshold distances are achieved, advantageously allowing the use of active signaling means 4 for those products 3 or compositions of products 3 that require an alert at a greater distance and passive signaling means 4 for those products 3 or compositions of products 3 that require an alert at a shorter distance

As illustrated in Fig. 3b, when the person 2 requiring supervision and the potentially dangerous product 3 are less than the predetermined threshold distance 8 from each other, the portable detection means 7 located on the person 2 detect the radio signal 5 emitted by the signaling means 4 of the product 3, thus determining a dangerous approach between the person 2 and the product 3. Thus, the portable detection means 7 will be provided with an antenna that will allow the detection of the radioelectric signal 5 that will contain an identification 6. In this way, after emitting the signaling means 4 located in the potentially dangerous product 3, the radioelectric signal 5 that includes the identification 6 of the product and/or the composition of the product 3, will allow detection, by the portable detection means 7 located on the person 2 requiring supervision, the radioelectric signal 5 emitted by the signaling means 4 c When the portable detection means 7 and the signaling means 4 of the potentially dangerous product 3 are less than a predetermined threshold distance 8 from each other.

After the portable detection means 7 detect the radioelectric signal 5, the portable detection means 7 will be able to extract the identification 6 of the product 3 and/or of the composition of the product 3 from the radioelectric signal 5 and trigger a warning of the approach between the person 2 and the potentially dangerous product 3 from the identification 6 of the product 3 and/or the composition of the product 3 extracted. In this way, by means of a query to the database 15 that can be stored locally in the portable detection means 7 or by means of a request to a server that provides access to the database 15, from the identification 6 extracted from the radioelectric signal 5 it will be possible to determine the product 3 or composition of the product 3 corresponding to the identification 6, which will indicate the product 3 or the composition of the product 3 to which the person 2 who requires supervision is approaching.

It is envisaged that the portable detection means 7 to trigger a warning of the approach between the person 2 and the potentially dangerous product 3 can emit an alert, for example, acoustic or light to alert other people in the environment of the approach, even being able to present the emergency action protocol 13 associated with the product 3 or the composition of the product 3 by means of a screen. This step of triggering a warning of the approach between the person 2 and the potentially dangerous product 3 may further comprise making an emergency telephone call to a predetermined telephone number.

It is also envisaged that in an alternative or complementary way, the portable detection means 7 can send a warning signal 16 to a surveillance device 10 to trigger a warning of the approach between the person 2 and the potentially dangerous product 3 from the identification 6 of the product 3 and/or of the composition of the product 3 extracted, as well as that the surveillance device 10 can in turn make an emergency telephone call to a predetermined telephone number. It is envisaged that this surveillance device 10 can be a computer and telecommunications device, provided with processor and memory assemblies, duly programmed and adapted to receive the warning signal 16. This warning signal 16 can be transmitted establishing a point-to-point communication between the portable detection means 7 and the surveillance device 10, which can be direct, for example through radio frequency communication with a previously established frequency and protocol between the portable detection means 7 and the surveillance device 10, or it can be routed in a known manner via different network nodes, for example the communication taking place via a network, such as a mobile phone network or the internet. For example, the portable detection means 7 could incorporate a mobile phone network card that allows the warning signal 16 to be sent to a network card of the surveillance device 10.

This surveillance device 10 will be adapted to receive a notification from the portable detection means 7, the surveillance device 10 being adapted to trigger a warning by generating an alarm signal 9 to warn of the approach between the person 2 requiring supervision and the product 3 potentially dangerous. It is further provided that the monitoring device 10 is provided with display means, adapted to display an emergency action protocol 13 to be carried out in the event of contact between the person 2 requiring supervision and the product 3 considered dangerous.

It is also contemplated that the monitoring device 10 is adapted to receive notifications from a plurality of portable detection means 7, for example, when the monitoring device 10 is located in a hospital for the monitoring of a group of patients. For this functionality, it is envisaged that each of the portable detection means 7 incorporates, for example, an identifier that makes it possible to determine the person 2 who requires supervision carrying the portable detection means 7 that have triggered the warning of the approach between the person 2 and a potentially dangerous product 3. This identifier could be incorporated in the notification that the portable detection means 7 sends to the surveillance device 10, for example, in the warning signal 16. It is also envisaged that a prior pairing or registration of the portable detection means can be carried out 7 and the surveillance device 10, so that parameters incorporated in the warning signal 16 can be used to identify the portable detection means 7 that have generated the warning signal 16, obtaining the data of the person 2 associated with the means of detection. laptop detection 7 for example of a database. One of these parameters incorporated in the warning signal 16 could be an identifier such as a unique identifier of the portable detection means, such as an IP or MAC address, when the communication between the portable detection means 7 and the surveillance device 10 is via network. Naturally, other known identifiers specific to the communication protocol between the portable detection means 7 and the surveillance device 10 could be used. It is also envisaged that the portable detection means 7 optionally inform the surveillance device 10 of its location, for example, if the portable detection means 7 are provided with a positioning system, such as GPS, so that it can be identified and located quickly to person 2.

In addition, the surveillance device 10 can be provided with a button to make an emergency telephone call to a predetermined telephone number, so that in an emergency situation a guard, guardian or caregiver can quickly contact emergency services. emergency.

Although the step of extracting the identification 6 of the product 3 and/or of the composition of the product 3 from the detected radioelectric signal 5 is expected to be carried out in the portable detection means 7, it is also foreseen that the portable detection means 7 will not carry out a processing of the radioelectric signal 5 and act as a gateway, forwarding the radioelectric signal 5 to other devices of the system 1 in which the information will be extracted

1

identification 6 of the product 3 and/or of the composition of the product 3 of the radioelectric signal 5, such as the surveillance device 10.

As presented in Fig. 3c, it is envisaged that after extracting the identification 6 of the product 3 and/or of the composition of the product 3 from the radioelectric signal 5 detected in the portable detection means 7, the portable detection means 7 send a warning signal 16 to a monitoring device 10 to trigger a warning of the approach between the person 2 and the potentially dangerous product 3 from the identification 6 of the product 3 and/or the composition of the product 3 extracted. This surveillance device 10 can be located in a remote location, for example, in an alarm center, and it is expected that the warning signal 16 can be routed and encapsulated by different devices of the system 1, being sent through different means until reaching the surveillance device 10. Naturally, it is also envisaged that the warning signal 16 received by the surveillance device 10 is directly the radioelectric signal 5, so that the surveillance device 10 has to extract the identification 6 from the product 3 and/or of the composition of the product 3 of the radioelectric signal 5, decoding it, and obtaining the corresponding data from the database 15, which can be stored locally or remotely in the surveillance device 10.

In this way and in the manner illustrated in Fig. 3c, the step of triggering a warning of the approach between the person 2 and the potentially dangerous product 3 comprises notifying the portable detection means 7 to a monitoring device 10 of the approach between the person 2 and the potentially dangerous product 3, so that the monitoring device 10 generates an alarm signal 9 of approach between the person 2 requiring supervision and the potentially dangerous product 3.

It is further envisaged that the method further comprises the step of obtaining and submitting an action protocol 13 associated with the product 3 and/or the composition of the product 3 to be carried out in the event of contact between the person 2 requiring supervision and the product. 3 considered dangerous based on the identification 6 of the product 3 and/or the composition of the product 3, for example, on a screen of the surveillance device 10.

Naturally, the method of the present invention could also be applied, for example, to domestic animals, applying the same criteria as for people, with the obvious differences in terms of the protocols to be carried out in each case.

1

It is also envisaged that the system 1 also advantageously allows preventing the contact of the person 2 who requires supervision with products 3 or compositions of products 3 that may lead to dangerous interactions, for example pharmacological interactions, and preferably pharmacological incompatibilities. As illustrated in Fig 3d, the method may further comprise the sequence of steps of detecting by the portable detection means 7, simultaneously with a first radioelectric signal 5, a second radioelectric signal 5a comprising a second identification 6a of a second product 3a and/or composition of the second product 3a, as this second product 3a is also less than the threshold distance 8 from the portable detection means 7 and therefore from the person 2 requiring supervision.

At this point it will be possible to determine if there is a relationship of danger due to pharmacological interaction 14 between product 3 and/or composition of product 3 and the second product 3a and/or composition of the second product 3a from identification 6 and the second identification 6a detected, for example by accessing their relationship of danger due to pharmacological interaction 14 previously registered in the database 15, which, as indicated above, can be local or remote. Naturally, the interaction hazard ratio 14 between the product 3 and/or composition of the product 3 and the second product 3a and/or composition of the second product 3a can be determined by the portable detection means 7, as well as other devices of the system 1 such as surveillance device 10.

In the event that products 3 and/or the composition of products 3 can produce dangerous interactions, preferably pharmacological interactions, more preferably pharmacological incompatibilities, an additional warning should be triggered of the approach between person 2, product 3 and the second product 3a. For example, in the manner illustrated in Fig. 3d this additional warning can be realized by the monitoring device 10 emitting a reinforced alarm signal 9a.

Logically, this novel functionality will force all the countries and health systems of each of them that decide to implement it to create an International File of products or active ingredients and/or elements that make up all the drugs and/or medications that currently exist, to database mode 15, and update it permanently with the new ones that are incorporated, and must be validated in each country by the corresponding Ministries of Health in order to avoid those unfortunate drug interactions that occur daily throughout the world due to lack of information and methodology for it. As a reference, the software and computer application will be able to communicate with infrastructures in the cloud and databases such as the one available at the European Medicines Agency (EMA), where all the technical data sheets for drugs and/or medicines are stored, in which They include, among other data, information related to drug interactions and/or incompatibilities.

Another field in which the functionalities of the method and system would be of great use would undoubtedly be in the control, administration and management in all the centers where they are used, of drugs to carry out chemotherapy treatments that, due to their high costs, traceability and dangerous use (alkylating agents, nitrosoureas, antimetabolites, antitumor antibiotics, topoisomerase inhibitors, mitosis inhibitors, corticosteroids, etc...) should only be able to be handled and subsequently administered to patients by identified persons and authorized to do so, using for this purpose, the devices mentioned and described above and provided with the corresponding software. Likewise, the portable detection means 7 would serve to track and locate the container and/or packaging 12 provided with the signaling means 4 containing the medication in the event of loss within a controlled area.

In addition, it is envisaged that the signaling means 4, for example, one or more RFID radiofrequency labels containing respective identifications 6, can be located not only in a container and/or packaging 12 of the product 3, but also in other elements or in their proximity, as shown in an illustrative manner in Fig. 4. Thus, it is anticipated that within the scope of the invention the term products does not only include chemical products and drugs and/or medicines, but that the products may be other elements that are wants to signal to avoid the proximity of the person 2 who needs supervision and who carries the portable detection means 7, such as doors, windows, wells or other dangerous places.
