Digital assistant appliance for assisting an operator in the manual preparation of a liquid pharmaceutical composition in a medical instrument for administering the composition to a patient, and corresponding operating method

摘要

Digital assistant appliance for assisting an operator in the manual preparation of a liquid pharmaceutical composition comprising: a memory device containing, for each active principle of the liquid pharmaceutical composition: one or more first sample images of vials containing the active principle, and one or more second sample images of syringes that can be used for transferring the active principle from the vials to the medical instrument; an artificial viewing system designed to acquire: a vial image of a vial chosen by the operator and/or a syringe image of a syringe chosen by the operator; and an electronic processing system configured in such a way as to compare the vial image with each of the first sample images for determining whether the vial chosen by the operator is incorrect, and/or compare the syringe image with each of the second sample images for determining whether the syringe chosen by the operator is incorrect, and warn the operator of an error condition in the preparation step when the vial or the syringe chosen by the operator is incorrect.

主权项

1. A digital assistant appliance configured to assist and to monitor an operator as the operator manually prepares a liquid pharmaceutical composition to be administered to a patient using a medical instrument, said appliance comprising:
a user-interface system configured to indicate, to the operator, operations to be performed by the operator to prepare the liquid pharmaceutical composition and to provide assistance preparation messages to the operator as the operator prepares the liquid pharmaceutical composition; a memory device configured to have stored thereon, for each active principle of the liquid pharmaceutical composition: one or more first sample images of vials that can contain said active principle, and/or one or more second sample images of syringes that can be used to transfer said active principle from the vials to the medical instrument; a scale positioned on a horizontal surface, the scale being configured to have positioned thereon, by the operator, a vial and/or a syringe; an artificial viewing system configured to acquire: a vial image of the vial positioned by the operator on said scale and/or a syringe image of the syringe positioned by the operator on said scale; and an electronic processing system configured to:
compare said acquired vial image with each of said first sample images and determine that an incorrect vial has been positioned on said scale by the operator, when said acquired vial image does not correspond to any of said first sample images;compare the acquired syringe image with each of said second sample images and determine that an incorrect syringe has been positioned on said scale by the operator, when said acquired syringe image does not correspond to any of said second sample images; andprovide a warning to the operator, through the user-interface system, when the electronic processing system determines that an incorrect vial and/or an incorrect syringe has been positioned on said scale by the operator.
