Definitions

  • the invention relates to a secure device for dispensing fluid to a user.
  • 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 in the context of the present application means a gaseous, liquid or diphasic liquid-gas body.
  • the opening of the fluid bottles is usually controlled by means of a plastic seal, a new plastic seal to be put back in place by the nursing staff after each use.
  • the presence of a new seal ensures that the bottle is not used in the meantime by personnel who do not hold such plastic seals, ie unauthorized personnel of the patient type.
  • the invention aims to remedy all or part of the disadvantages of the state of the art identified above, and in particular to provide means for securing access to containers adapted to contain the fluid, such as fluid bottles.
  • the device conditions the unlocking of the valve of the container, 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 adequacy between the authentication information of the user and the predetermined value contained for example in a memory of the secure device.
  • the nature of the authentication means and 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 stripe card, smart card etc ...
  • the use of a contactless communication improves the reliability of the system, because of the absence of contact zone, this type of zone being worn over time. This communication technology should preferably allow the establishment of a short-distance communication, low consumption and embedding security layers.
  • the authentication information may be information about the medical personnel authorized to administer the treatment, or information about the patient to receive the treatment, or both information at a time.
  • the type of authentication information expected depends on the setting of the device and the predefined authentication information which may be the sum of the authentication information of the medical staff and the patient.
  • valve is not necessarily opened, i.e. passed to its second state, immediately.
  • the medical staff user, may have to perform preliminary medical steps, such as preliminary care.
  • the opening of the unlocked valve can be done manually by the medical staff.
  • the second state of the valve corresponding to the opening of the valve may 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 may be a housing adapted for insertion of the user authentication means, or may also be a push button that the user activates so as to wake 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 may be of the type: card, keychain, mobile device (mobile phone, tablet, computer, 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 retrieving it on a remote means.
  • a remote server could manage the authorization of use of the bottles and a means of authentication of the mobile phone type retrieves this authorization on the remote server by means of a communication type 3G for example, then it establishes a connection of communication with the secure device whose type depends on the interface installed on the secure device.
  • the secure device could include a plurality of interfaces, each interface can establish a different type of communication link depending on the nature of the authentication means available to users.
  • the method may advantageously comprise a prior step of awakening the interface by the detection means. This step may be carried out by an 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 activation once it has been activated. it has been detected.
  • the method for safely dispensing a fluid to a user by means of the secure dispensing device comprising means adapted to make the valve evolve 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 may advantageously comprise a step of transmitting the predefined intermediate state of the valve of the user authentication means to the secure device
  • the predefined intermediate state of the valve corresponds to a dosage in flow, in this case the administration of the fluid is done at a precise flow rate, i.e. for a predefined intermediate state of the valve.
  • the secure device could comprise calculation means for converting this value into a flow rate in a predefined intermediate state of the valve, ie a specific valve position. , or calibrated orifices, on the passage of the fluid in the valve.
  • the authentication of a user for unblocking the device is enhanced.
  • the predetermined value is not stored on the secure device but on a remote server with which the secure device requests verification of the identity of the user.
  • the method may include a step of transmitting fluid quantities / fluid flow 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 comprises a valve 2.
  • the fluid contained in the container 1 is distributed towards the outside of the container 1 (in the direction of the arrow shown in FIG. 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 outwards and a second state in which it is open, allowing the fluid to be dispensed to the fluid.
  • This second state may correspond to a total opening of the valve or to a predefined intermediate opening, corresponding to a specific flow rate of the fluid distribution.
  • the device further comprises control means 6 activatable by a control signal.
  • the control means 6 are connected to the locking means 3 so as to be able to move it from the first position, in which it blocks the valve, to the second position, in which it no longer blocks the valve.
  • the device further comprises a detection means 4 for detecting the presence of an authentication means 5 of the user.
  • 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 awake.
  • the device comprises an interface 7, which is an RFID reader, in this embodiment.
  • the interface 7 enables 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 in 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 woken up, activates the RFID tag of the user's RFID badge by supplying the necessary energy.
  • the communication channel is established only if the detection means 4 detects the presence of an authentication means 5, which thus limits the power consumption of the device.
  • the RFID tag 5 comprises an authentication information of the user to whom it belongs and information on the posology in fluid flow and duration of administration of the fluid, in this embodiment.
  • the authentication information is transmitted to the secure device over 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 pass the locking means 3 in the second position, in which the valve is no longer locked in the closed position. In this way, the valve 2 is free of movement and can move 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 can not unlock the secure fluid dispensing device.
  • the RFID badge also includes information concerning the dose rate of the fluid to be administered to the patient by the user.
  • the device comprises means, of the type valves, or calibrated orifices, adapted to evolve 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 flow rate information of the fluid transmitted by the RFID badge via the communication channel.
  • Valves, or calibrated orifices make it possible to vary the opening section of the valve between the fully open and fully closed position.
  • a fluid flow measurement means D is positioned at the outlet of the valve.
  • the flow measurement means D may 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. When activated, the display means may display an alert message to the user or beep.
  • the RFID badge in this embodiment, also includes information regarding the dosage of fluid administration time to the patient that defines a predetermined period of time after which the valve must return to the first position, in which it is closed .
  • the user when the user opens the valve, once it has been unlocked by the locking means, 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 engage a movement of the electromechanical device adapted to disarm 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 to know the capacity of said container. It is connected to a computer of the display means A so as to prevent in order to activate the display means when the pressure of the fluid contained in the container will not complete the treatment determined by the dosage or when the bottle is empty.
