PRESSURE MEASURING DEVICE, SERVING FOR DETERMINATION OF LIQUID PRESSURE IN THE DEVICE FOR DISPENSION OF MEDICINAL LIQUID Russian patent published in 2018 - IPC A61M5/142 A61M5/168 G01L19/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. Fluid container is intended for use in a dispensing device. Container contains a rigid body, which limits the volume of the drug liquid to the inside of its wall, and a membrane that overlaps the opening of the rigid body, forming a fluid-tight lid, the opening corresponding to the measurement zone. Membrane further overlaps the portion of the outer side of the wall of the rigid body. Membrane has a flexible measuring part corresponding to the opening of the rigid body, a fastening part that is attached to the rigid body, and a connecting portion that connects the flexible measuring portion to the fastening portion and comprises a rigid portion, the upper portion of which is connected to the flexible measuring portion. Rigid portion has a sealing surface and a deformable portion with which a rigid portion is attached to the fastening portion. Fluid container further has a first gap between the rigid portion and the rigid body, dimensioned to allow at least a portion of the rigid portion to be inserted therein when applying a force to the sealing surface, causing deformation of the deformable part. Pressure measuring device is disclosed that includes a fluid container.

EFFECT: technical result consists in increasing the reliability and reproducibility when assembling the container and ensuring the measurement of the pressure of the drug medium in the container.
