Systems and methods are provided for transferring fluid between a container and a reservoir. In an embodiment, a system may include a container having an interior volume configured to hold a volume of fluid. An adapter may be associated with the container for providing fluid communication with the volume of fluid. A receiver may be configured to be fluidly coupled with a reservoir. The receiver may be configured to releasably engage the adapter, and may include a valve configured to be opened when the adapter is engaged with the receiver to allow fluid transfer between the container and the reservoir.

The invention relates to a fluid transfer system, a fluid transfer method and a biochemical substance analysis system.The fluid transfer system comprises a fluid storage module, a fluid using module, a fluid quantitative driving module and an air pressure control module, the fluid storage module is used for storing fluid, the fluid using module is provided with a flow channel, and the liquid inlet end of the flow channel is communicated with the fluid storage module; the liquid outlet end of the flow channel is communicated with the fluid quantitative driving module, and the fluid storage module is further communicated with the air pressure control module; the air pressure control module is used for providing pressure for the fluid storage module and enabling the liquid inlet end of the flow channel to maintain a positive pressure environment; the fluid quantitative driving module is used for generating driving force, so that the fluid in the fluid storage module is quantitatively transferred to the flow channel. The fluid transfer system is simple in structure and low in cost, the risk of gas precipitation in fluid can be reduced, the quality of biochemical reaction can be improved, meanwhile, the flow speed of the fluid can be more flexibly regulated and controlled, and it is guaranteed that the liquid passing amount in a flow channel is consistent every time.

Systems and methods for the transfer of medical fluid are provided. A medical fluid transfer system may comprise a pump configured to transfer fluid through a tube assembly having a first connector configured to couple to a source container and a second connector configured to couple to a target container. The medical fluid transfer system may also comprise a destination sensor configured to output information about the target container. The medical fluid transfer system may further comprise a control system configured to operate the pump based on an operational setting associated with fluid volume; receive measurement data representing a measurement of the target container by the destination sensor, and adjust the operational setting based on an observed volume of fluid transferred to the target container.

The invention provides a recovery tank, a fluid transfer control method of the recovery tank, and an inertia valve operation method for suppressing fluid surge in the recovery tank. The recovery tank comprises a first fluid cavity, a second fluid cavity, a fluid passage and an inertia valve; the fluid passage is used for connecting the first fluid cavity and the second fluid cavity; the inertia valve is used for controlling the opening degree of the fluid passage and comprises a valve plate, the valve plate can move between a first position and a second position, when the valve plate is located at the first position, the inertia valve allows fluid of a first flow flowing through the fluid passage to transfer from the first fluid cavity to the second fluid cavity, and when the valve plate is located at the second position, the inertia valve allows fluid of a second flow flowing through the fluid passage to transfer from the first fluid cavity to the second fluid cavity. The inertia valve allows a second flow rate of fluid flowing through the fluid passage to divert from the second fluid chamber to the first fluid chamber, where the first flow rate is greater than the second flow rate.

An implantable fluid operated expandable device (200) may include a fluid reservoir (202) configured to hold a fluid, an expandable member (204), and a fluid structure providing fluid transfer between the fluid reservoir and the expandable member. The fluid reservoir, expandable member, and fluid structure may be included in a single unit or a single housing, thus providing a relatively compact implantable fluid operated expandable device. The relatively simple, compact device allows for simplified insertion into a patient and allows for simplified user operation.

A sliding riser system is provided herein which may include at least one moving riser bar attached at a first end to a showerhead, at least one fixed inlet waterway connected to a fluid line, and a balance spring mechanism which may include a balance spring attached at a free end to the at least one moving riser bar. The fluid line may provide water to the sliding riser system, and thereby, to the showerhead for use. A portion of the moving riser bar may be housed within the fixed inlet waterway, or a portion of the fixed inlet waterway may be housed within the moving riser bar. Such housing may cause fluid flowing in the fixed inlet waterway to transfer and flow into the moving riser bar.
