A device for performing an ophthalmic procedure in an eye including a hand-held portion; an elongate member extending from a distal end region of the hand-held portion; and an aspiration pump within the hand-held portion. The elongate member includes a lumen and an opening near a distal end region of the elongate member. The aspiration pump is in fluid communication with the opening of the elongate member. The aspiration pump includes a camshaft extending along a longitudinal axis and having a plurality of lobed cams; tubing extending parallel to the longitudinal axis; and a plurality of cam followers driven by the cams of the camshaft to move in a plane perpendicular to the longitudinal axis to sequentially compress the tubing. Related devices, systems, methods are provided.

Devices used to collect bodily fluids are disclosed. The devices may include a fluid bag and a transformable hanger for mounting the fluid bag to a support structure such as a hospital bed rail. The fluid bag can include a first fluid compartment and a second fluid compartment. The devices may further include a displaceable front cover and a back cover to obscure the bodily fluids from observation.

Systems and methods can determine whether a patient is attached to a respiratory device (such as to via a patient interface) by analyzing a flow parameter signal in the time domain. Additionally, the processes can classify the patient attachment status into one of the four categories: detached, attaching, attached, or detaching. The system can include a non-sealed patient interface, such as a nasal cannula in a nasal high flow therapy, or any other patient interfaces. Data of the patient's use of the respiratory system can provide therapy compliance and long-term trend of use information and/or progress in the patient's respiratory functions and/or other physiological functions.

An aspiration control device can have an aspiration control valve and a switch, button, slider, trigger, grip, lever, rotating wheel, rotating valve, handle or other interface for resizing the aspiration control valve. The aspiration control interface can be conveniently positioned and configured to be manipulated while simultaneously stabilizing a catheter and/or retracting an elongated member. The aspiration control device can be integrated with a hemostasis valve, integrated with a wire gripping device, and/or attached to an inlet, outlet, hose, pump, or syringe in series with an aspiration flow path.

Described is a medical adapter assembly comprising an end including a neuraxial fitting that is not directly connectable to a standard luer fitting, an opposing end including a fitting connectable to an intravenous medical device, and a check valve that allows fluid flow from the end with the standard luer fitting to the end with the neuraxial fitting, but prevents fluid flow from the end with the neuraxial fitting to the end with the standard luer fitting. Methods of using the medical adapter assembly and kits containing the medical adapter assembly are also described.

Methods of treating a medical condition in a patient include performing a lipectomy of visceral fat to remove a quantity of the visceral fat from the subject. The removal of visceral fat treats the medical condition such that the subject experiences at least a reduction of symptoms of the medical condition.

A system includes a respiratory device, a mask, a microphone, a speaker, and a control system. The respiratory device is configured to supply pressurized air. The mask is coupled to the respiratory device and configured to engage a user during a sleep session to aid in directing the supplied pressurized air to the user. The microphone is configured to generate audio data. The speaker is configured to emit sound. The control system is configured to analyze the audio data to determine if noise associated with air leaking from the mask is occurring. Responsive to (i) the analysis resulting in a determination that noise associated with air leaking from the mask is occurring, (ii) the respiratory device determining that air is leaking from the mask, or (iii) both, the speaker is caused to emit the sound to aid in masking the noise associated with the air leaking from the mask.
