A pumping system comprising a pump comprising a door for access within a housing of the pump, a pump segment configured for conveying a fluid based on compression of the pump segment, a pump segment frame for preventing said pump segment from stretching, a visual placement indicator configured for facilitating in a proper placement of the pump segment frame in the housing, and a non-pinching valve configured to be disposed in the housing and to control a flow of the fluid without requiring pinching of a tube.

A syringe is provided having a hub with an orifice, first and second barrels having interior surfaces to form respective lumens, a slider, and an optional test indicator. The first and second barrels slideably receive respective first and second plungers for movement therein. The slider is operable to provide a fluidly communicative path between the orifice of the hub and the first and second barrel lumens. The optional test indicator is responsive to at least one characteristic of bodily fluid, the test indicator positioned to be exposed to any bodily fluid drawn into the first barrel lumen and visible from an exterior of the first barrel.

A liquid supplying device for a human insulin injection includes a substrate, a liquid storage chamber, a flow-guiding-and-actuating unit, a sensor and a driving chip. The flow-guiding-and-actuating unit includes a liquid guiding channel having a liquid guiding outlet in fluid communication with a liquid storage outlet of the liquid storage chamber. The sensor contacts with the human skin to measure a blood glucose level contained in sweat. The driving chip is configured to control the actuation of the flow-guiding-and-actuating unit, control open/closed states of the switching valves and receive the measured data from the sensor for determination. By driving the flow-guiding-and-actuating unit, a pressure gradient is generated, and an insulin liquid stored in the liquid storage chamber is transported to the liquid guiding outlet through the liquid guiding channel, flowing into a microneedle patch, and injected into a subcutaneous tissue through a plurality of hollow microneedles.

A connector is provided comprising a first hollow connector body having an inner face including a slot, and an outer face, the first hollow connector body having an aperture passing through the inner face and the outer face; a second hollow connector body having an inner face including a slot, and an outer face, the second hollow connector body having an aperture passing through the inner face and the outer face; and, a fluid transfer member, interposed between the first hollow connector body and the second hollow connector body, wherein the fluid transfer member is slidably arranged in the slot of the inner face of the first hollow body and the slot of the inner face of the second hollow body to provide slidable movement between a first fluid transfer position and a second fluid transfer position.

A connector is provided comprising first and second hollow connector bodies, the connector having a first expanded position providing a first fluid flow path through the first hollow connector body, and a second collapsed position providing a second fluid flow path through the first and second hollow connector bodies.

A valve comprises a housing in which a movable valve element having first and second valve members is disposed. A plurality of ports are disposed in the housing, and first and second seal portions are connected to the housing. At least one of the first seal portion and the first valve member is deformable such that, when only the first seal portion is in a sealed configuration with the first valve member, deformation allows the second seal portion to be brought into a sealed configuration with the second valve member, and/or at least one the second seal portion and the second valve member is deformable such that, when only the second seal portion is in a sealed configuration with the second valve member, deformation allows the first seal portion to be brought into a sealed configuration with the first valve member.

A valve mechanism for a suction instrument or an irrigation instrument includes a valve object; a first piston moveably disposed in the valve object; a second piston moveably disposed in the valve object; and a piston buckling unit pivoting on an outside of the valve object. When the first piston is pressed, the first piston moves downward, and a first buckle on the first piston is fixed on a third buckle of the piston buckling unit to open an irrigating pathway. When the second piston is pressed, the second piston moves downward, and a second buckle on the second piston is fixed on another third buckle of the piston buckling unit to open a suction pathway.

A blocked end portion of a cylinder is provided closer to a distal end side in a direction of insertion of the piston into the cylinder than a minimum diameter portion. The blocked end portion includes a minimum diameter uniform portion which has the same inside diameter as the minimum diameter portion and a partial diameter increased portion which has an inside diameter that is increased as compared to the inside diameter of the minimum diameter portion.

Hand-operated suction and irrigation medical devices are provided. An example medical device comprises a housing having a proximal end and a distal end. The housing defines first and second inlet paths and an outlet path. A first tubular member is partially disposed within the first inlet path and a second tubular member is partially disposed within the second inlet path. Each of the first and second tubular members extends from the proximal end of the housing. A third tubular member is partially disposed within the outlet path and extends from the distal end of the housing. A control member is slidably disposed on the housing and is movable between a first, proximal position and a second, distal position. A passageway provides fluid communication between the first inlet path and an opening to an environment external to the housing such that covering the opening provides control over the flow of fluid through the first inlet path and the first tubular member.

The apparatus (1) is designed to mix at least two ingredients coming from at least two distinct reservoirs (2, 3). It has at least two distinct orifices (6, 7) suitable for being connected to the reservoirs (2, 3), a motor-driven pump (15), a fluid-connection selector (9) including at least one network of through channels (12) suitable for putting at least one of the orifices into communication with the pump (15), the fluid-connection selector (9) being arranged to be movable between a plurality of positions in order to make it possible, selectively and by means of the pump (15), to transfer at least one ingredient from one orifice to the other orifice or towards the pump (15) and to blend the resulting mixture.
