Definitions

  • a secure method of delivering fluid to a user is provided.
  • the invention relates more particularly to the distribution of fluid contained in bottles intended for patients in a non-hospital environment, in the context of home care.
  • fluid means a gaseous, liquid or two-phase liquid-gas body.
  • the opening of the fluid bottles is generally controlled by means of a plastic seal, a new plastic seal to be replaced by the nursing staff after each use.
  • the presence of a new seal guarantees the non-use, in the meantime, of the bottle by personnel who do not have such plastic seals, i.e. unauthorized personnel of the patient type.
  • the invention aims to remedy all or part of the drawbacks of the state of the art identified above, and in particular to provide means making it possible to secure access to the receptacles suitable for containing the fluid, of the fluid bottle type.
  • the device conditions the unlocking of the valve of the container, on the authentication of the user who presents his means of authentication.
  • the use and administration of the fluid contained in the container is conditioned on the match between the user's authentication information and the predetermined value contained for example in a memory of the secure device.
  • the nature of the authentication means and of the communication channel depends on the type of interface installed on the secure device. Any communication technology of the type with or without contact is possible: RFID, NFC, WIFI, magnetic strip card, smart card, etc.
  • the use of contactless communication improves the reliability of the system, due to the absence of contact zone, this type of zone wears out over time. This communication technology should preferably allow the establishment of a short distance communication, low consumption and embedding layers of security.
  • the authentication information can be a information concerning the patient to receive the treatment, or else both information concerning the medical personnel authorized to administer the treatment and information concerning the patient to receive the treatment.
  • the type of authentication information expected depends on the configuration of the device and the predefined authentication information which may be the sum of the authentication information of the medical personnel and of the patient.
  • valve is not necessarily open, i.e. passed to its second state, immediately.
  • the medical personnel the user, may have to carry out preliminary medical steps, of the preliminary care type. Opening of the unlocked valve can be done manually by medical personnel.
  • the second state of the valve corresponding to the opening of the valve can be a total opening of the valve or a partial opening, i.e. an intermediate opening determined by the dosage required by the patient.
  • the detection means can be a housing suitable for the insertion of the user authentication means, or also be a push button that the user activates so as to wake up the device and allow the establishment of the communication channel. for its authentication.
  • the authentication means used by the user and capable of communicating with the secure device for the exchange of authentication information can be of the type: card, key ring, mobile device (mobile phone, tablet, computer, etc. etc.). It can be any type of means capable of establishing a communication link with the interface chosen for the device and capable of storing authentication information or else of retrieving it on a remote means.
  • a remote server could manage the authorizations to use the bottles and a means of authentication of the mobile telephone type retrieves this authorization from the remote server by means of a communication of the 3G type for example, then it establishes a connection of communication with the secure device, the type of which depends on the interface installed on the secure device.
  • the secure device could include a plurality of interfaces, each interface being able to establish a different type of communication link depending on the nature of the authentication means available to the users.
  • the method can advantageously include a preliminary step of waking up the interface by the detection means.
  • This step can be performed by a operator pressing a push button for example or by the authentication means which sends a wake-up signal to the detection means which itself sends it to the interface for its activation once it has been detected.
  • the method of secure distribution of a fluid to a user by means of the secure distribution device comprising means adapted to cause the valve to move to a predefined intermediate state between the first state in which the valve is closed and the second state in which the valve is fully open can advantageously include a step of transmitting the predefined intermediate state of the valve from the user authentication means to the secure device
  • the predefined intermediate state of the valve corresponds to a flow rate dosage, in this case the administration of the fluid takes place at a precise flow rate, i.e. for a predefined intermediate state of the valve.
  • the secure device could include calculation means for converting this value into flow rate in a predefined intermediate state of the valve, ie a specific position of the valves. , or calibrated orifices, on the passage of the fluid in the valve.
  • the authentication of a user for unblocking the device is reinforced.
  • the predetermined value is not stored on the secure device but on a remote server from which the secure device requests verification of the user's identity.
  • the method may include a step of transmitting the quantities of fluid / the flow rate of fluid to be delivered from the remote server to the secure device when the authentication information is equal to the predetermined value. This information can be integrated into the acknowledgment signal or sent separately.
  • the device comprises a container 1 adapted to contain the fluid, preferably a fluid for medical use.
  • the container 1 is of the fluid bottle type.
  • the container 1 has a valve 2.
  • the fluid contained in the container 1 is distributed to the outside of the container 1 (in the direction of the arrow shown in figure 1 ) by means of the valve 2.
  • the valve 2 has a first state in which it is closed, thus preventing the fluid from exiting to the outside and a second state in which it is open, allowing the fluid to be distributed to the outside.
  • This second state may correspond to a total opening of the valve or else a predefined intermediate opening, corresponding to a specific flow rate of distribution of the fluid.
  • the device further comprises control means 6 which can be activated by a control signal.
  • the control means 6 are connected to the locking means 3 so as to be able to pass it from the first position, into which it blocks the valve, in the second position, in which it no longer blocks the valve.
  • the device further comprises a detection means 4 for detecting the presence of a user authentication means 5.
  • the authentication means 5, of the badge type in this embodiment can be inserted into a slot / housing of the detection means 4 comprising for example a push button.
  • the secure device is awakened.
  • the device comprises an interface 7, which is an RFID reader, in this embodiment.
  • the interface 7 allows the establishment of a communication channel between the secure device, via the interface 7, and the authentication means 5, which is of the RFID badge type in this embodiment.
  • the badge When the user inserts the RFID badge into the detection means 4, the badge activates the establishment of the communication channel.
  • the RFID communication channel is established by the RFID reader 7 which, once awakened, activates the RFID marker of the user's RFID badge, providing it with the necessary energy.
  • the communication channel is only established if the detection means 4 detects the presence of an authentication means 5, which thus makes it possible to limit the energy consumption of the device.
  • the RFID badge 5 includes authentication information for the user to whom it belongs and information on the dosage in terms of the flow rate of the fluid and the duration of administration of the fluid, in this embodiment.
  • the authentication information is transmitted to the secure device by the established communication channel. If this authentication information corresponds to a predetermined value that the bottle recognizes, a control signal is generated, for example, by a computer C connected to the interface 7.
  • the computer C is connected to the control means 6 and the signal control generated by the computer C activates them so that they cause the locking means 3 to pass into the second position, in which the valve is no longer blocked in the closed position. In this way, the valve 2 is free to move and can pass from the first position to the second position and vice versa.
  • the control signal would not have been generated and the locking means would have been maintained by the control means 6 in the first position, ie the position in which it blocks the valve. Thus, an unauthorized user cannot unlock the secure fluid distribution device.
  • the RFID badge in this embodiment, also includes information relating to the flow rate dosage of the fluid to be administered to the patient by the user.
  • the device comprises means, of the valve type, or calibrated orifices, suitable for changing the valve between the first state, in which it is closed and the second state in which it is open, the valve adopting an intermediate position predefined between the first state and the second state.
  • the predefined intermediate position corresponds to the information concerning the dosage in flow rate of the fluid transmitted by the RFID badge by means of the communication channel.
  • the valves, or calibrated orifices make it possible to vary the opening section of the valve between the fully open and fully closed position.
  • a means for measuring the flow rate of the fluid D is positioned at the outlet of the valve.
  • the flow rate measuring means D can be connected to a computer of a display means A in order to activate the display means when the actual flow rate does not correspond to the expected flow rate.
  • the display means may display an alert message to the attention of the user or emit an audible signal.
  • the RFID badge in this embodiment, also includes information concerning the dosage in duration of administration of the fluid to the patient which defines a predetermined period of time after which the valve must return to the first position, in which it is closed. .
  • the user arms a return means (not visible in the figure) of the spring type.
  • the spring is connected to an electromechanical device to which the predetermined period of time is transmitted by the interface 7 so as to initiate a movement of the electromechanical device adapted to cause the disarming of the spring once the time has elapsed.
  • the device also comprises a means for measuring the pressure P of the fluid contained in the container making it possible to know the capacity of said container. It is connected to a computer of the display means A so as to be able to warn in order to activate the display means when the pressure of the fluid contained in the container will not allow to complete the treatment determined by the dosage or when the bottle is empty.
