Abstract
The invention relates to a holding means for holding an oxygenator and a blood pump. The holding means is characterised by a frame that can be connected with a carrying case housing in a torque-proof way for fitting the oxygenator and the blood pump relative to each other, wherein the frame has a frame section for connection with the oxygenator in a torque-proof way and another frame section for connection with the blood pump in a torque-proof way.
Core Innovation
The invention describes a heart-lung machine holding means comprising a frame configured to hold an oxygenator and a blood pump. The frame includes a first frame section and a second frame section, each configured to be coupled to the respective component in a torque proof way. A handle is connected to the first and second frame sections to enable handling while the relative angle and alignment of the oxygenator and blood pump is fixed prior to patient use.
The frame is configured to be partly arranged in a carrying case housing, wherein the handle is arranged outside of the carrying case housing. The carrying case housing is configured to receive and hold the frame. The carrying case protects components and reduces transport and alignment time, while providing routing and guiding of fluid, gas, and branch lines, including a branch line to analysis means.
The carrying case is described as including housing sections with openings and/or recesses for inspection, spare parts, and sensors, and a closing cover enabling fluid connection without fully disconnecting sections. Passage openings are provided for fluid lines, and a condensate fluid outlet is included. A footprint and positioning arrangement positions an oxygenator inlet vertically above a blood pump outlet, and the system includes currentless and electrically driven blood pump options as well as gas-source control/regulation of flows, including retraction and ventilation valves for branch and lines.
Claims Coverage
The document provides one independent claim covering a heart-lung machine system with a torque-proofly connected frame and a carrying case that receives the frame while leaving the handle outside. Inventive features are further narrowed by dependent claims that specify carrying-case construction details and positional, fluid-routing, and pump/drive aspects; the listed inventive features below reflect the main elements recited across the independent claim and its cited dependent refinements.
Torque-proof frame holding of oxygenator and blood pump
A frame configured to hold an oxygenator and a blood pump, wherein the frame comprises a first frame section configured to be coupled to the oxygenator in a torque proof way and a second frame section configured to be coupled to the blood pump in a torque proof way.
Handle connected to torque-proof frame sections
A handle, connected to the first and second frame sections.
Carrying case receiving the frame with handle outside housing
A carrying case, comprising a carrying case housing, wherein the carrying case housing is configured to receive the frame, wherein the carrying case housing is configured to hold the frame, and wherein the frame is configured to be partly arranged in the carrying case housing with the handle arranged outside of the carrying case housing.
Sectional carrying-case housing with passage openings for fluid lines
A carrying case, wherein the carrying case housing comprises first housing section and second housing section and includes passage openings for routing fluid line(s) connected to the oxygenator and/or the blood pump and/or for passage of a portion of the frame.
Fluid outlet passage and branch line to analysis means
A carrying case, wherein the carrying case housing includes a fluid outlet passage and further includes a passage opening from which at least one branch line extends to supply blood to an analysis means.
Blood pump driven currentless or by gas through fluid lines
A system including a blood pump driven without current or driven by gas flowing through one or more fluid lines.
Footprint positions oxygenator inlet vertically above blood pump outlet
A configured footprint, that when the carrying case is placed on a positioning surface positions an oxygenator inlet vertically above a blood pump outlet.
Retractable or non-protruding fluid and branch lines relative to carrying case housing
Fluid line(s) and/or branch line(s) associated with the carrying case housing are configured to be retractable into the housing or prevented from retracting/protruding beyond the housing.
Across the independent claim and the cited refinements, the coverage centers on a torque-proofly coupled frame for an oxygenator and a blood pump, a carrying case that holds the frame while keeping the handle outside the housing, and additional structural features for routing fluid/branch lines (including to analysis means), managing fluid outflow, supporting currentless or gas-driven blood pump operation, positioning the oxygenator inlet vertically above the blood pump outlet, and constraining retraction/protrusion of lines.
Stated Advantages
Protects components.
Reduces transport and alignment time.
Documented Applications
Hospital bed and emergency usage, including a bed fitting device with a movable holder.
