  • the end user is able to manually control breast pumps individually with the help of a visualized control panel (see Figure 21 in the prior art) and by a selection of control presets, i.e. start, stop or change a pumping cycle, increase or decrease each pump peak pressure, or switch between different pre-program pressure profiles such as one mimicking the sucking pattern of a baby during an expression or stimulation cycle.

  • a control preset is selected from at least two control presets defining the selected control preset.
  • the position of the throttle may continuously be visualized on the breast pump and/or a visualized control panel of the second control device.
  • the present invention provides the advantage that the method can be conducted more user- friendly.
  • the control may easily be implemented via apps on a smartphone.
  • the possibility to control via a hand held device such as a smartphone contributes to mother’s comfort because commonly she is used to using a smartphone and because of the self-explanatory visualization of the control as to what control preset is selected.
  • the throttle is self explanatory in that it is inherently clear to the end user what the min/max threshold of the presently adjusted kind of control preset is.
  • the throttle can be adjusted in discrete steps or continuously, the later allowing the user to select any value intermediate of a maximum and a minimum value of a control parameter and/or control preset.

Abstract

La présente invention concerne un procédé de commande d'un tire-lait (2) comportant une source d'aspiration (4), un moyen de connexion (6) et un premier dispositif de commande (10), le premier dispositif de commande (10) étant conçu pour commander la source d'aspiration (4), et le premier dispositif de commande (10) étant connecté par l'intermédiaire du moyen de connexion (6) à un second dispositif de commande (100) qui est un dispositif portatif séparé du tire-lait (2), le procédé comprenant les étapes consistant - à fournir, sur le second dispositif de commande (100), au moins deux préréglages de commande (PR1, PR2, PR3, PR4), chacun desdits deux préréglages de commande (PR1, PR2, PR3, PR4) comprenant l'un d'au moins deux paramètres de commande (P1, P2, P3) destinés à commander le premier dispositif de commande (10), - à sélectionner, sur le second dispositif de commande (100), un préréglage de commande (PR1, PR2, PR3, PR4) desdits deux préréglages de commande (PR1, PR2, PR3, PR4) en tant que préréglage de commande sélectionné (PR-SEL), - à envoyer, au moyen du second dispositif de commande (100), le paramètre de commande (P1, P2, P3, P4) du préréglage de commande sélectionné (PR-SEL) au premier dispositif de commande (10) et à commander le premier dispositif de commande (10) au moyen dudit paramètre de commande (P1, P2, P3, P4), le préréglage de commande sélectionné (PR-SEL) étant sélectionné par une position d'un papillon (116) qui peut coulisser sur une surface d'un panneau de commande visualisé (110) du second dispositif de commande (100) pour définir la position du papillon (116). La présente invention concerne en outre un tire-lait (2), un code de programme informatique pour mettre en œuvre le procédé et un second dispositif de commande (100) tel qu'un téléphone intelligent exécutant le code de programme informatique.
