Abstract
A suction pump system for aspirating body fluids from a patient is disclosed. The suction pump system includes a housing, at least one pump unit, and a one fluid collection container, which is connected to the pump unit via a vacuum line. The at least one pump unit is arranged in the housing, and the housing has more than one fixture for releasably and simultaneously holding the fluid collection container. The suction pump system allows a patient's body fluids to be aspirated from different sites simultaneously. The suction pump system is easy to operate, affords the user great flexibility in terms of the choice of drainage, and permits a good overview of the chosen applications.
Core Innovation
The invention relates to a suction pump system for aspirating body fluids from a patient. The suction pump system includes a housing with an upper side and a side wall, and at least one pump unit arranged in the housing. The housing further has a first and at least one second fixture on the side wall for receiving fluid collection containers, with the first fluid collection container releasably held in the first fixture and each second fixture capable of simultaneously holding a further fluid collection container.
The first fixture and the at least one second fixture are arranged next to one another in the side wall of the housing. The first fluid collection container and the at least one further fluid collection container are arranged next to each other protruding the side wall of the housing in the same direction. Each of the fluid collection containers is at least partially visible when arranged in the fixtures, and multiple containers are positioned for simultaneous arrangement next to each other.
The system further provides a first input and display unit and at least one second input and display unit arranged on the upper side of the housing. The first input and display unit and the at least one second input and display unit are arranged next to each other in a line, forming a parallel line to the arrangement of the fluid collection containers. The first input and display unit is assigned to the first fluid collection container and arranged opposite to the first fluid collection container, and each second input and display unit is assigned to one of the second fluid collection containers and arranged opposite to that assigned container.
Claims Coverage
Independent claim clm-00001 defines the core mechanical and human-machine arrangement: pump units in a housing, multiple fluid collection containers simultaneously held in side-wall fixtures next to each other, and correspondingly arranged input/display units assigned to respective containers in an opposite, parallel line configuration. Dependent claims add further inventive relationships and structural refinements, including drainage-line connection relationships, assignment of multiple containers to a pump unit, and control electronics assignment in groups, as well as a modular architecture and portability.
Side-wall fixtures for simultaneously holding multiple fluid collection containers with side-by-side visibility
A housing with a side wall having a first and at least one second fixture, with the first fluid collection container releasably held in the first fixture and each second fixture capable of simultaneously holding a further fluid collection container, wherein the fixtures are arranged next to one another and the containers protrude the side wall in the same direction and are at least partially visible.
Parallel line arrangement of input and display units assigned opposite corresponding containers
A first and at least one second input and display unit arranged on the upper side of the housing next to each other in a line, forming a parallel line to the arrangement of the fluid collection containers, where the first input and display unit is assigned to the first fluid collection container and arranged opposite to it, and each second input and display unit is assigned to one of the second fluid collection containers and arranged opposite to that container.
Drainage lines with a one-to-one connection to separate fluid collection containers
The suction pump system includes drainage lines connecting the fluid collection containers to the patient, wherein each drainage line is connected to a separate one of the fluid collection containers.
Multiple fluid collection containers assigned to a single pump unit
In the suction pump system, more than one fluid collection container is assigned to one single of the at least one pump unit.
Grouped pump units assigned to a single control electronics unit
A group of pump units where all pump units in the group are assigned to a single one of the control electronics units.
Modular architecture of pump, containers, control electronics, and input/display units
The pump unit, fluid collection containers, a control electronics unit and an input/display unit are arranged as modules, with at least two such modules included.
Portability of the suction pump system
A portable suction pump system as set forth in the suction pump system of claim 1.
Across the independent claim and its refinements, the system coverage centers on side-wall, simultaneously held, side-by-side fluid collection containers with corresponding, parallel-line input and display units arranged opposite their assigned containers, with dependent features specifying drainage-line connections, container-to-pump assignment relationships, shared control electronics for groups, a modular architecture, and portability.
Stated Advantages
Enables simultaneous aspiration from different patient sites (e.g., cardio and pleura drainage).
Improves monitoring by preventing mixing.
Avoids Y-connector blockage risk.
Provides an easy-to-operate modular layout with clear mapping between containers and associated input/display units.
Documented Applications
Simultaneous patient aspiration from different body cavities/sites, including cardio drainage and pleura drainage.
