Embodiment Construction

[0042] In the following description, various specific details are provided to enable a better understanding of the embodiments provided by way of example. Embodiments may be practiced with or without the specific details, or with other methods, components, materials, and the like. In other instances, well-known structures, materials, or operations are not shown or described so as not to obscure aspects of the embodiments. Reference in the specification to "an embodiment" or "one embodiment" means that a specific detail, structure or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of phrases such as "in an embodiment" or "in one embodiment" at various points in the specification do not necessarily refer to one and the same embodiment. Furthermore, particular features, structures or characteristics may be combined in any convenient manner in one or more embodiments.

Abstract

Wearable device for dispensing fluids and corresponding dispensing method, comprising a fixation part (30; 70) wearable by a subject and a , a replaceable part (20; 60) comprising a container (21; 61) for containing the fluid to be dispensed and a micropump (22; 62), in particular of the MEMS type and intended to be connected via the fluid (12; 51 ) sends the fluid to a stationary part (30; 70) comprising an electrical control module (31) configured to control the operation of the micropump (22; 62) via a pressure sensor device (23; 76) ; 71), the device (10; 50) comprising an actuator (25; 75; 175) arranged to automatically operate said micropump (22; 62). According to the invention, the pressure sensor device (76) is arranged in the fixed part (70) of the fluid connection (51), in particular adjacent to the terminal end of the fluid connection (51) associated with the needle (74) for dispensing the fluid Export Department.

Description

technical field [0001] The present disclosure relates to a wearable device for dispensing fluids comprising a fixed portion worn by a subject and a replaceable portion associable to the fixed portion via a fluid connection, the replaceable portion comprising a A container of dispensed fluid and a micropump for sending the fluid through a fluid connection to said stationary portion, said stationary portion comprising an electrical control module configured to control the operation of the micropump, the apparatus comprising a micropump for operating said A battery actuator for a micropump. [0002] Various embodiments are applicable to devices for dispensing fluids, where the fluids contain insulin or other pharmaceutical preparations. Background technique [0003] Devices are known for dispensing fluids, eg containing insulin or other pharmaceutical preparations, which can be worn by the user or patient so as to be able to dispense the fluid continuously or on demand or, and...
