The invention provides for a cartridge (100, 200, 300, 500, 500', 500", 602, 602', 602", 1100, 1100', 1200, 1200', 1300, 1300', 1400, 1400', 1600, 1900, 1900', 1900", 2000, 2100, 2200, 2300, 2500, 2600) for dispensing a fluid (123). The cartridge comprises: a rigid portion (102), a flexible bladder (104), and an outlet (108). The outlet is attached to the rigid portion. The rigid portion comprises an inner cavity (116). The outlet is connected to the inner cavity. The rigid portion comprises an opening (114). The opening is connected to the inner cavity. The flexible bladder seals the opening to form a fluid chamber (122) from the inner cavity.
摘要:
A cartridge for dispensing a fluid is presented. The cartridge comprises a reservoir chamber for receiving the fluid. The reservoir chamber has a fluid outlet. The cartridge further comprises a controllable dispenser component for dispensing a dispensing volume of the fluid from the reservoir chamber. The dispenser component is connected to the fluid outlet of the reservoir. The cartridge further comprises a single compressible fluid pump with a single elastic pumping element and a conduit extending from the fluid pump towards the fluid outlet. The fluid pump discharges a mixing volume of the fluid from the conduit into the reservoir chamber upon compression of the elastic pumping element. The mixing volume depends on the degree of compression of the elastic pumping element. The fluid pump sucks in the mixing volume from the reservoir into the conduit upon decompression of the elastic pumping element.

The present disclosure refers to a sensor device (1, 1'), a method of operating the sensor device (1, 1') and an IVD analyzer (100) for receiving the sensor device (1, 1') for determining chemical and/or physical characteristics of a fluid. The sensor device (1, 1') comprises at least two fluidic conduits (2, 2', 3) for repeatedly receiving fluids, each fluidic conduit (2, 2', 3) comprising at least one sensory element (11A, 11B, 12A, 12B, 13, 14, 15) arranged such as to come in contact with a fluid in the respective fluidic conduit (2, 2', 3). In particular, the fluidic conduits (2, 2', 3) comprise different sensory elements, respectively, wherein the sensory elements are separated in the respective fluidic conduits according to compatibility or susceptibility to deterioration or operating temperature. Alternately, the fluidic conduits (2, 2', 3) comprise at least in part the same sensory elements, wherein the sensor device (1, 1') is operated in a primary operating mode and in response to a trigger event, switches to an extended operating mode.

The invention provides for a method of determining an amount of an analyte in a blood sample (500) using a cartridge (100, 300, 600) and a blood collector (400, 800, 1200, 1513). The blood collector comprises: a mounting surface (402); a capillary structure (404) for holding the blood sample, wherein the capillary structure comprises a curved portion (406); a capillary inlet (403) for receiving the blood sample. The cartridge comprises: a receiving surface for attaching to the mounting surface; a cartridge inlet (108) for receiving the blood sample from the blood collector; a microfluidic structure (111) for processing the blood sample into a processed sample; a measurement structure (130) for enabling measurement of the processed sample to determine the amount of the analyte in the blood sample; wherein the method comprises: placing (1100, 1400) the blood sample into the capillary inlet; attaching (1104, 1404) the mounting surface to the receiving surface; rotating (1600) the cartridge about the rotational axis to transport the blood sample from the capillary structure to the cartridge inlet; rotating (1602) the cartridge about the rotational axis to transport the blood sample from the cartridge inlet into the microfluidic structure; controlling (1604) the rotation of the cartridge about the rotational axis to process the blood sample into the processed sample using the microfluidic structure; controlling (1606) the rotation of the cartridge to transfer the processed sample to the measurement structure; and measuring (1608) the amount of the analyte using the measurement structure and a measurement system.

The invention provides for a method of performing an optical measurement (1132) of an analyte in a processed biological sample using a cartridge (100). The cartridge is operable for being spun around a rotational axis (108). The method comprises: placing the biological sample into a sample inlet (112); controlling (1200) the rotational rate of the cartridge to process a biological sample into the processed biological sample using a fluidic structure (110); controlling (1202) the rotational rate of the cartridge to allow the processed biological sample to flow from the measurement structure inlet to an absorbent structure via a chromatographic membrane, and performing (1204) an optical measurement of a detection zone (122) on the chromatographic membrane with an optical instrument. An inlet air baffle reduces evaporation of the processed biological sample from the chromatographic membrane during rotation of the cartridge
