Method for monitoring the dispensing of a drop and assistance device

A method for monitoring a dispensing of a drop by a device for dispensing a liquid in a form of drops, using a detector for detecting the liquid, said detector is arranged near an orifice for dispensing the drops of the liquid, and a system for processing information provided by the detector, a monitoring method during which the processing system receives information corresponding to the following series of steps:

• a step of detecting a presence of the liquid, during which the detector detects the presence of the liquid near the dispensing orifice, the detector being configured such that the detection of the presence of the liquid is indicative of the drop of the liquid while being formed, the drop being in contact with the dispensing orifice,
• after the step of detecting the presence of the liquid, a step of detecting an absence of the liquid, during which the detector detects the absence of the liquid near the dispensing orifice
• and the processing system processes information on the series of steps of detecting the presence of the liquid and detecting the absence of the liquid in order to provide information on the dispensing of the drop, wherein the processing system identifies an occurrence of a sequence of the step of detecting the presence of the liquid followed by the step of detecting the absence of the liquid to indicate the dispensing of the drop, wherein the step of detecting the absence of the liquid of the sequence is a last step of liquid detection steps of the sequence.
