Devices and methods for controlling intracompartmental pressure in muscle compartments and, potentially, reducing the incidence of compartment syndrome are disclosed. A device according the invention is a thin, elongate member with an outer layer. The device has a proximal end, which has a coupling constructed and adapted to connect with tubing, and a distal end. The outer layer is at least somewhat permeable to liquids and to cells, either by way of perforations along its length or because of its natural properties. Within and encased by the outer layer lies a core, also porous, and typically an open-celled foam. The core is compressible under the range of suction pressures typically applied in medical contexts. A guide wire may initially be present in the device to aid in its placement. Methods for making such devices, especially on an ad hoc basis, are also disclosed.

Provided is a medical suction device including a compressible object comprising a surface, an opening in the surface, and a lumen defined by the surface and the opening, along with a tubular member located inside the compressible object. Also provided is a medical suction apparatus including the medical suction device and a catheter dimensioned to fit inside the tubular member of the device. A method of removing liquid from the throat of a subject using the medical suction apparatus is also provided, as well as kits including the medical suction device.

Methods and apparatuses for automatically switching different aspiration levels to an ocular probe are disclosed herein. The probe may be a phacoemulsification probe. A first aspiration level, supplied by a first pump, may be applied to the probe simultaneously with ultrasonic energy. A second aspiration level, supplied by a second pump, may be automatically switched from the first aspiration level. Control feed back of the pumps may be varied according to set thresholds.

Certain embodiments provide an apparatus comprising a hand-piece, an outer tube coupled to the hand-piece, an inner tube housed within the outer tube and having a distal end coupled to a soft tip and a proximal end coupled to an adapter, a proximal end of the adapter coupled to a distal end of a valve, the valve slidably coupled to the hand-piece, and a core slidably coupled to the hand-piece and having a distal end coupled to a proximal end of the valve. To retract the soft tip, the valve is retracted, causing the adapter, the valve, and the core to slidably retract in a proximal direction in relation to the hand-piece, and to extend the soft tip, the valve is protracted, causing the adapter, the valve, and the core to slidably protract in a distal direction in relation to the hand-piece.

Some embodiments are directed to a system 10 for the application of topical negative pressure therapy to a site 18 on the body of a mammal. Some embodiments of the system 10 comprise a piston 22 and cylinder 24 device 12 having a self-contained power source for the generation of a reduced pressure and for aspirating the site 18. Some embodiments of the system 10 comprise a dressing 14 sealably surrounding the site 18 that can be operably connected to the device 12 by a conduit means 16 to apply the reduced pressure to the site 18.

An aspiration thrombectomy system, comprising an aspiration catheter having a proximal end and a distal end, wherein the proximal end of the aspiration catheter comprises a lumen configured to accommodate fluid, a vacuum source comprising a controllable vacuum valve, and a controller configured to detect a change in a connection between the aspiration catheter and the aspiration thrombectomy system, wherein the controller is further configured to change a pulsation protocol associated with the aspiration catheter responsive to the change in the connection between the aspiration catheter and the aspiration thrombectomy system, wherein the pulsation protocol specifies pressure variations and pressure patterns to modulate the vacuum valve to change a level of vacuum at the distal end of the aspiration catheter.

System and methods for analyzing the contents of a fluid canister are provided for use in healthcare settings. The system includes optical and weight sensors to analyze the canister contents.

The present disclosure discloses a device for automatically collecting snot, which comprises a suction nozzle, a collecting cup, a cup holder and a shell component which are detachably connected in sequence, wherein the shell component is a hollow cavity. The present disclosure generates negative pressure suction through the air pump, and then the suction air enters the inner collecting cup through the air suction pipe, the cup holder air inlet, the air inlet channel and the micropore in sequence. Finally, the suction sucks the snot in the nose of a user into the inner collecting cup through the suction nozzle, effectively solving the problem of snot reflux.

A syringe for withdrawing an aspirate from a body for micro fat grafting is provided. The syringe includes a barrel having an inner wall extending therein. The inner wall has one or more apertures formed therein allowing the aspirate to contact an absorbent positioned between the inner wall and an outer wall of the barrel. A plunger moves longitudinally within the barrel along the inner wall and has a gasket attached to a proximal end forming a seal against the inner wall. The absorbent may take many forms to absorb a non-fat cell portion of the aspirate. A related method includes retracting the plunger from a first position to draw the aspirate from a harvest site of a body into the barrel, exposing the aspirate to the absorbent, and moving the plunger toward the first position so a remaining portion of the aspirate is no longer exposed to the absorbent.

A clot capture module can include a housing, a chamber inside the housing, a window, and a filter. The window permits visual inspection of a clot inside the chamber. The clot can access the chamber via an incoming flow path configured to direct blood from an aspiration catheter to an upstream surface of the filter. An aspiration control valve can block the flow of incoming aspirated blood until actuated to permit inflow of aspirated blood. An outgoing flow path can direct blood from a downstream surface of the filter to a remote vacuum canister.
