INFUSION DEVICE Russian patent published in 2025 - IPC A61M5/142 A61M39/28 

FIELD: medicine.

SUBSTANCE: invention relates to infusion devices for delivering medical fluids, such as drugs or nutrient solutions to patients. Infusion device comprises a housing and a door of the pump assembly. Body is configured to receive an infusion line and comprises a pump mechanism. Pump mechanism is configured to allow the medical fluid to flow through the infusion line inserted into the body. Pump assembly door is configured to be connected to the body for closing the body and configured to fix the infusion line in place in the body. Pump assembly door comprises clamping element. Clamping element has clamping protrusions and a groove. Clamping projections are made on both ends of the clamping element, along the longitudinal direction of the clamping element. Upper surfaces of the clamping projections are shaped so that to enable the infusion line reception. Groove is located at intermediate place between clamping projections and has the possibility of being deepened in direction of clamping element height so that it is located below clamping projections.

EFFECT: invention provides the possibility of good fixation of the infusion line in a predetermined position in the infusion device, without causing overlapping of the infusion line, allows more accurate detection of bubbles in the infusion line, can provide accurate positioning of the liquid flow stopping mechanism, fluid flow stop mechanism operates more smoothly and does not wear out during the opening and closing process.
