Abstract
There is a process and a system for removing body fluids from a body opening. The system can comprise a container having an inflow port and an outflow port. The inflow port is coupled to a fluid conduit, the outflow port is coupled to a pump. In one embodiment, disposed in the outflow port is a coagulant agent for coagulating bodily fluids. There can be one or more filters coupled to the container as well. In one embodiment at least one filter is coupled to the outflow port to prevent coagulated bodily fluids from leaving the container and flowing towards the pump. There can also be a process which involves providing at least one coagulant in the container, wherein the coagulant for coagulation of the body fluids and storing the coagulated body fluids in the container. There is also a process for assembling the container as well which in one embodiment includes providing both a coagulant and a filter coupled to the container. The container can also include support ridges or ribs suitable to support intake ports or outflow ports or surfaces of the container.
Core Innovation
The invention relates to a body-fluid collection system and process that uses a container supported in an oblique manner above a surface and subject to negative pressure. Body fluids are pumped from a body opening into the container using a pressure pump creating negative pressure in the container. The container includes at least one inflow port for entry of the body fluids and at least one outflow port for removal via a fluid conduit coupled to the pump.
A coagulant is positioned in or near the outflow-side fluid path upstream of at least one filter to coagulate the body fluids within the conduit. The system provides at least one filter fluidly coupled with the outflow port and disposed within the conduit upstream of an outflow end of the outflow port, and an additional filter positioned upstream of the at least one coagulant and adjacent to the outflow end. The additional filter functions for preventing body fluids from exiting the outflow port and damaging the pump while coagulated body fluids are trapped for storage.
The system further provides removable filter arrangements, including frames or filter support structures and removable filter elements such as PTFE filters. Container structural features include ribs/support ridges and a base section configured with offset supports to enable an oblique or tilting container orientation. The integration described includes a schematic system using a wound dressing and a pump with the container and filtration/coagulation components to collect coagulated or solidified body fluid.
Claims Coverage
The patent document presents three independent claims. The inventive features across these claims focus on an obliquely supported, negative-pressure body-fluid collection container; a conduit-based coagulation and filtration arrangement that includes a pump-protecting additional filter; and removable filter(s) in the outflow conduit.
Oblique container under negative pressure with inflow and outflow ports
A process providing a container supported via a stand such that the container extends in an oblique manner above a surface, pumping body fluids from the body opening into the container using a pressure pump creating negative pressure, and providing at least one inflow port and at least one outflow port for entry of the body fluids into the container.
Conduit filtration with upstream coagulant and pump-protecting additional filter
Providing at least one filter fluidly coupled with the outflow port and disposed within a fluid conduit upstream of an outflow end of the outflow port; providing at least one coagulant positioned upstream of the at least one filter within the conduit for coagulation of the body fluids within the conduit; and providing at least one additional filter positioned upstream of the at least one coagulant and adjacent to the outflow end of the outflow port to prevent body fluids from exiting the outflow port and damaging the pump.
Removable outflow conduit filtration arrangement with coagulant disposed between removable filters
A container for receiving body fluid comprising a housing with a base, an intake port coupled to the housing for entry of the body fluids, and an outflow port coupled to the housing with a conduit and an end; a stand supporting the housing in an oblique manner above a surface; at least one filter coupled to the housing disposed in the conduit of the outflow port adjacent to and upstream from the end; at least one coagulant disposed in the conduit upstream of the at least one filter; and at least one additional filter disposed in the conduit and coupled to the coagulant opposite the at least one filter such that the coagulant is disposed between the at least one filter and the at least one additional filter, with the at least one filter and the at least one additional filter removable.
Across the independent claims, the document centers on an obliquely supported container that receives body fluid under negative pressure and routes fluid through an outflow-side conduit where a coagulant is positioned relative to filter(s), including an additional filter to prevent pump damage. The container claim further specifies a removable filter arrangement disposed in the outflow conduit around the coagulant.
Stated Advantages
Prevents body fluids from exiting the outflow port and damaging the pump.
Traps coagulated body fluids in the container for storage.
Documented Applications
Collection and handling of coagulated or solidified body fluid in a body-fluid collection system integrated with a wound dressing and a pump, as described in the schematic system integration.
