The present disclosure relates to a devices and methods to control suction during medical procedures, and more particularly to medical suction devices, systems, and methods for controlling suction using the portable suction devices/systems during endoscopic procedures. For example, the present disclosure includes a portable suction device in fluid communication with an endoscope system, the portable suction device including: a suction regulator device releasably coupled to and in communication with at least one suction tube of the endoscope system, the at least one suction tube in fluid communication with an endoscope of the endoscope system and a suction source of the endoscope system, wherein the suction regulator device is actuatable to at least one of increase or decrease a suction force within the at least one suction tube.

A system and apparatus for the collection of serous or serosanguinous fluid from a percutaneous site after surgery. A pump unit with one or more pumps or powered sources provide continuous negative pressure suction to draw fluid from the percutaneous site and pumps the fluid into disposable reservoirs with one-way valves that are easy to handle while maintaining sterility and a seal to prevent the loss of vacuum. Air is continuously removed from the reservoirs. Measurement and analysis of the output is performed automatically. Additionally, through such a peristaltic pump device, controlled collection of measured surgical and/or bodily fluid from a subject patient may be undertaken allowing for more effective and closer analysis, as well.

A nasal aspirator suction bin assembly comprises a suction bin base, which has a first connecting end connected with a host and a second connecting end connected with a suction bin cover; after the suction bin base is connected with the suction bin cover, a cavity is formed therein; the middle of the suction bin base is provided with an outlet tube, which runs through the suction bin base and extends into the cavity; the upper end of the suction bin cover is provided with a suction tube, which runs through the suction bin cover and extends into the cavity; a bracket is arranged in the cavity, and the bracket comprises a bracket tube which can be inserted on the outlet tube and a baffle arranged at the other free end of the bracket tube, and at least one air hole is arranged on the bracket tube to keep the suction tube and the outlet tube in communication all the time; the cavity is used to store the inhaled nasal fluid. Because of the umbrella-shaped bracket, the nasal fluid cannot touch the position of the air hole during normal use and small-angle inclined use, so the nasal fluid cannot enter the host and cause pollution.

A nasal mucus suction device includes an air pump and a head structure. The air pump has an intake tube and an outlet tube. The head structure is coupled to the intake tube and the outlet tube of the air pump, and defines a channel between a nasal mucus suction inlet and a gas outlet. The channel includes a first channel section in communication with the nasal mucus suction inlet, and a second channel section in communication with the gas outlet. The first channel section includes at least one mucus storage cavity, the second channel section is in communication with the intake tube and the outlet tube of the air pump. The first channel section has a maximized path length, and includes an anti-backflow channel structure. The second channel section includes a noise reduction space.

A manifold for a medical waste collection apparatus includes a fluid path connection portion and a storage connection portion. The storage connection portion includes a mounting connector in communication with the fluid path connection portion and coupled with the mounting base of the waste collection apparatus, and a docking valve arranged inside a connector cavity defined by inner walls of the connector. The docking valve is in an open state when the mounting connector is coupled with the mounting base, and a passage is formed between the storage connection portion and a waste collection container in the waste collection apparatus. The docking valve is in a closed state to close the connector cavity when the mounting connector is decoupled. The connection port between the manifold and the apparatus does not require manual opening or closing, thereby preventing waste from contaminating the environment, equipment and personnel, and enhancing convenience of use.

A collection liner for a medical or a surgical operation is disclosed which includes a closed bag portion and inlets opening into the bag portion. The collection liner can include a handle which includes at least one of the inlets inside the handle.

A manifold for a medical waste collection system. A filter element is disposed within a housing and includes a basket, and a seal retaining element coupled to the basket. The seal retaining element supports the seal in sealing engagement with a rim of the housing. The basket may be disposed within a body portion of the housing, and the seal retaining element may be disposed within a first leg of the housing. The seal may define a groove, and the seal retaining element may be partially disposed within the groove. The seal retaining element may define an aperture, and a tongue of the seal may be resiliently deflected into the aperture by an inner surface of the housing. The seal may have a width greater than a height to be noncircular, and may include flaps defining a seal aperture oriented widthwise.

A method for detecting a state of a dressing includes measuring air pressure within a tube. The tube provides airflow between a pump device and the dressing. The method also includes determining whether the air pressure differs from a pressure setpoint by more than a preset limit, and running the pump to cause the air pressure to approach the pressure setpoint. In response to a determination that the air pressure does not differ from the pressure setpoint by more than the preset limit, the method also includes determining a duration of time since a last running of the pump, determining whether the duration of time since the last running of the pump exceeds a threshold duration, and, in response to a determination that the duration of time since the last running of the pump exceeds the threshold duration, generating an alert that indicates that the dressing is full.

Devices for collecting patient excretions utilize existing suction sources and facilitate the cleaning of bedding and/or a patient. Patient excretion collection devices comprise a collection reservoir and a collection wand which are attached to an existing source of suction.

A reduced-pressure system for delivering reduced pressure for medical purposes to a desired site and to receive fluids in one instance includes a reservoir having an interior space operable to contain the fluids. A reduced-pressure delivery conduit is placed in fluid communication with the interior space for delivering the reduced pressure to the desired site. A source conduit and a pressure sensor conduit are placed in fluid communication with the interior space. A pressure sensor is placed in fluid communication with the pressure sensor conduit. A reduced-pressure source is placed in fluid communication with the source conduit. A reduced-pressure control unit is associated with the pressure sensor and the reduced-pressure source and is operable to receive pressure data from the pressure sensor and supply data from the reduced-pressure source and to determine when a reservoir-full/blockage condition exists. Other systems and methods are presented.
