A portable suction pump for aspirating secretions from a patient's artificial airway includes a peristaltic pump head, a suction tube extending from a patient through the peristaltic pump head, the suction tube having a tee-fitting conduit, and a collection container having a plurality of ports for collecting patient media. A clinician has an ability to increase or decrease vacuum levels without increasing or decreasing flowrate and/or an ability to increase or decrease the flow rate without increasing or decreasing the vacuum levels. The tee-fitting conduit extends to a vacuum sensor port connecting to a vacuum sensor in communication with a processor, the processor controlling a proportional valve employed to regulate the vacuum levels.

Devices and methods for managing chest or wound drainage are disclosed where in one embodiment, the system generally comprises a chest tube configured for insertion at least partially within a body of a subject, a drainage tube fluidly coupled with the chest tube, a reservoir fluidly coupled with the drainage tube, a pump in communication with the reservoir, and a controller in fluid communication with the drainage tube. The controller may be configured to determine a readiness for removal of the chest tube from the body based upon one or more removal parameters which are obtained over a period of time via the controller.

A wound therapy system includes a dressing sealable over a wound and defining a wound space between the dressing and the wound, tubing fluidly communicable with the wound space, and a canister fluidly communicable with the tubing. The canister, the tubing, and the dressing define a sealed space that includes the wound space. The wound therapy system also includes a therapy unit coupled to the canister. The therapy unit includes a sensor configured to measure a pressure in the sealed space, a valve positioned between the sealed space and a surrounding environment and controllable between an open position and a closed position, and a control circuit. The control circuit is configured to control the valve to alternate between the open position and the closed position to allow airflow through the valve, receive measurements from the sensor, and determine a volume of the wound space based on the measurements.

A clot removal system comprises a catheter, a vacuum source, and a controller. The catheter comprises a proximal end, a distal end, and controller operating parameters and defines a lumen configured to be filled with a liquid column having a proximal portion. The vacuum source is configured to supply vacuum. The controller is configured to carry out a control pattern of turning on and off the vacuum based upon the controller operating parameters and is configured to receive the controller operating parameters in an automatic response to the catheter being operatively connected to at least one of the vacuum source and the controller and, responsive to the connection, to carry out the control pattern to change a level of vacuum at the distal end of the catheter.

System and methods for automatically removing by suction urine voided by a female. The systems include an external catheter and an integrated suction regulator or a stand alone external catheter for use with any source of regulated suction. The external catheter includes a suction tube an a fluid pervious cover. The catheter's cover is applied at the female's urethra opening to receive urine voided by the female, whereupon urine from the external female catheter passes through the cover into the suction tube, from which it is carried by out of the external catheter for collection. The external catheter is malleable so that it can be conformed to the anatomy of the female.

A system includes (i) a solenoid valve, positioned between a handle of a probe, and an aspiration line coupled with the handle for aspirating fluids from the probe, the solenoid valve includes at least a solenoid coil and a plunger movable by the solenoid coil, (ii) a sensor, positioned between the handle and the aspiration line and configured to produce a signal indicative of a fluid metric in the aspiration line, and (iii) a controller, configured to identify, based on the signal, a vacuum surge in the aspiration line, and, in response to identifying the vacuum surge, to apply at least one current to the solenoid coil to selectively move the plunger between a first position and a second position, and to selectively maintain the plunger in the first position and the second position.

An airway assist device and methods of making and using an airway assist device to assist in opening an airway or removing fluid or material obstructing an airway of a subject.

An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.

Systems and methods for dynamically modulating aspiration in response to sensed conditions. An aspiration system can include a catheter configured to be inserted within a vasculature of the subject, a canister coupled to the catheter, a pressure source that generates a vacuum pressure through the catheter for aspirating the fluid, a sensor configured to sense a parameter associated with at least one of the catheter, the canister, or the pressure source, and a computer system coupled to the sensor. The computer can cause the pressure source to initiate the vacuum pressure throughout the catheter, receive a measurement of the parameter from the sensor, determine whether the measurement violates a threshold associated with the parameter, and modulate the vacuum pressure at the catheter tip in response to a determination that the measurement violates the threshold.

Methods of assembling a manifold for a medical waste collection system. A flapper valve unit is secured to a head of a cap. A filter element is positioned within a shell. Basket hands of the filter element are fitted between first pairs of ribs of the cap skirt. Fingers of the shell are fitted between second pairs of ribs of the cap skirt. The cap is secured to the shell to cover an open distal end of the shell. A drip stop is secured to the proximal end base of the shell to seat within the outlet opening. Ears may be fitted through holes defined by the flapper valve unit and cap holes defined by the cap so as to snap lock to the head of the cap. The hub of the flapper valve unit may be compressed with the ears snap locked to the head of the cap.
