Abstract
A fluid collection reservoir for receiving an aspirated fluid has a secretion connection for connecting a drainage tube situated at a patient's side, and a vacuum connection for connecting to a suction pump. The reservoir has an interior space which is divided by means of ribs. The interior space is divided at least into a vacuum chamber and a secretion chamber, with said two chambers being connected to one another by means of at least one passage. The vacuum connector is arranged in the vacuum chamber and the secretion connector is arranged in the secretion chamber. This reservoir prevents contamination of the suction line or of the suction pump with aspirated fluid.
Core Innovation
The invention relates to a portable medical aspiration pump with a detachable fluid collection reservoir that receives aspirated fluid and isolates aspirated fluid from a suction pump via separate connections. The reservoir has a secretion connection for connecting a drainage tube situated at a patient's side and a vacuum connection for connecting to a suction pump. The interior space of the reservoir is divided by means of ribs into at least a vacuum chamber and a secretion chamber.
The vacuum chamber is arranged in an upper region of the reservoir and the vacuum connector is arranged in the vacuum chamber, while the secretion connector is arranged in the secretion chamber. The vacuum chamber and the secretion chamber are connected to one another by means of at least one passage. An intermediate chamber is arranged between the vacuum chamber and the secretion chamber, with a vacuum passage running from the vacuum chamber to the intermediate chamber and an intermediate passage running from the intermediate chamber to the secretion chamber.
An inclined rib is arranged adjacent to the vacuum chamber in an upper region of the secretion chamber. The inclined rib extends over a significant part of the width, but not over the entire width, and extends over the entire depth of the reservoir. This rib-based interior geometry, together with the passage arrangement, forms a reservoir interior in which aspirated fluid is guided toward the secretion chamber rather than communicating directly between vacuum and secretion regions.
Claims Coverage
The independent claim covers a rib-divided fluid collection reservoir for a portable medical aspiration pump, including an upper vacuum chamber and lower secretion chamber connected via passage(s) through an intermediate chamber, and featuring an inclined rib adjacent to the vacuum chamber. Additional dependent claims refine internal fluid-flow and connectivity constraints and further subdivide the secretion chamber with vertical ribs into interconnected sub-chambers.
Rib-divided vacuum and secretion chambers with separate connections
A fluid collection reservoir for receiving an aspirated fluid, having a secretion connection for connecting a drainage tube at a patient's side and a vacuum connection for connecting to a suction pump, wherein the reservoir interior space is divided by ribs into at least a vacuum chamber and a secretion chamber.
Upper vacuum region and connector placement with passage-connected chambers
The vacuum chamber is arranged in an upper region of the reservoir, the vacuum connector is arranged in the vacuum chamber, the secretion connector is arranged in the secretion chamber, and the vacuum chamber and secretion chamber are connected to one another by means of at least one passage.
Intermediate chamber between vacuum chamber and secretion chamber
An intermediate chamber is arranged between the vacuum chamber and the secretion chamber, wherein a vacuum passage runs from the vacuum chamber to the intermediate chamber and an intermediate passage runs from the intermediate chamber to the secretion chamber.
Inclined rib adjacent to the vacuum chamber
An inclined rib is arranged, adjacent to the vacuum chamber, in an upper region of the secretion chamber, said inclined rib extending over a significant part of the width, but not over the entire width, of the reservoir, and said inclined rib extending over the entire depth of said reservoir.
No direct connection between vacuum chamber and secretion chamber
There is no direct connection between the vacuum chamber and the secretion chamber.
Vertical rib subdivision of the secretion chamber into sub-chambers
The secretion chamber is divided by means of vertical ribs into sub-chambers, wherein the sub-chambers are connected to one another.
Overall, the claims primarily cover a reservoir interior that isolates vacuum and secretion functions through rib-based chamber division, an intermediate chamber with vacuum passage and intermediate passage, and an inclined rib adjacent to the vacuum chamber to guide aspirated fluid toward the secretion chamber. Dependent refinements explicitly constrain vacuum-to-secretion connectivity and further subdivide the secretion chamber into interconnected sub-chambers.
