The nebulizer gas scavenging system includes a condenser positioned in the expiratory pathway of the breathing circuit for extracting liquid from expiratory gases and redirecting the extracting liquid to the input of the nebulizer. The system is further configured to detect the actual consumption of inhaled medication by measuring the concentration of medication in the expiratory pathway and comparing it to the initial content of medication in the aerosol of the inspiratory pathway. A more accurate determination of the amount of inhaled medication is advantageous in certain critical situations involving application of medication by inhalation.

The invention is a wearable breast pump system including a housing shaped at least in part to fit inside a bra and a piezo air-pump. The piezo air-pump is fitted in the housing and forms part of a closed loop system that drives a separate, deformable diaphragm to generate negative air pressure. The diaphragm is removably mounted on a breast shield.

Nanoparticles are suspended in a fluid medium which is activated using an ultrasonic transducer in contact with the fluid medium. The fluid may be injected into a body cavity and ultrasonically activated to induce a cavitation effect. The body cavity may contain a natural or artificial hard surface, inflamed or with a biofilm harnessing bacteria, such as a bone, joint or implant, as well as the surrounding tissue. In an embodiment, a treatment device may be used before, during or after a procedure such as a minimally invasive or open surgery to disinfect the body cavity via irrigation with liquid containing suspended nanoparticles and ultrasonically activated. The irrigation device may supply the cavity with the liquid and include therein an ultrasonic transducer. The cleaning and disinfecting process may be performed as treatment of infection in absence of another surgical procedure.

Light weight, compact, battery powered, body-worn devices and systems are configured to allow automated, hands-free monitoring and care intervention, such as of an infant, by providing audio and/or physical stimulus when a negative comfort or health condition is detected by the body-worn device and system, and by monitoring the infant's temperature, pulse, and oxygen levels. The body-worn device preferably includes a flexible printed circuit board (“FPCB”) that allows the device to be conformed to the wearer's body, and has a plurality of linear resonant actuators affixed to the FPCB that are configured to impart soothing vibrations from the device to the wearer. A control program is provided and executable on a remote computing device, which control program is configured to enable users (such as a caregiver) to selectively control the actuators. The device may include a water-resistant casing covering its internal components, including the actuators, FPCB, battery, and those portions of on-board sensors not intended for direct monitoring contact with the wearer.

Infusion devices are disclosed herein. The present technology includes, for example, an infusion device for delivering a medicament to a body of a user. The device can comprise an insertion assembly comprising a cannula, a reservoir assembly comprising a reservoir configured to receive a medicament, and a trigger assembly configured to trigger insertion of the cannula into the user in response to a command from a remote computing device communicatively coupled to the infusion device.

Disclosed is a method for initializing an ambulatory infusion system. The method includes providing a liquid drug cartridge including a cartridge body, and a cartridge piston. The method further includes providing a dosing unit including a metering pump unit with a dosing cylinder and a dosing piston. The dosing unit further includes a valve unit configured for switching between a filling state and a draining state. The filling port being fluidically coupled with the dosing cylinder in the filling state and the draining port is fluidically coupled with the dosing cylinder in the draining state. The method further includes a) exerting an initialization force displacing the cartridge piston, and b) increasing a fluidic volume of the dosing cylinder by displacing the dosing piston, thereby sucking liquid out of the liquid drug cartridge into the dosing cylinder and further displacing the cartridge piston, without the initialization pushing force being exerted.

The removing device is configured to remove a needle cover removably mounted on a distal tip of an injection device comprising a barrel. The removing device comprises a housing including a holder configured to hold the injection device and a needle cover remover configured to remove the needle cover from the injection device, a first abutment member provided on the holder and being configured to abut against the injection device, a second abutment member provided on the needle cover remover, and being configured to abut against the needle cover, and displacement means configured to displace the needle cover remover relative to the holder in a translational direction so that the first and second abutment members translationally move away from each other in order to separate the needle cover from the injection device.

A medical implant includes a primary tubular member having a first end and a second end and defining a primary longitudinal axis and a primary lumen. The primary tubular member is disposed in an arterial-venous connection. The medical implant also includes a baffle disposed transversely to the primary longitudinal axis within the primary lumen. The baffle defines at least one aperture therethrough.

A pathogen detection system includes a pathogen sensing adaptor that detect pathogens present in the breathing circuit associated with a ventilated patient. A pathogen sensing adaptor may include a conduit, removable cartridges with testing strips, an optical sensor, and communication circuitry. Upon detecting a colorimetric change on the testing strip, the optical sensor generates a signal indicative of the presence and/or level of pathogens.

Delivery systems and methods for forming and delivering biomaterials from two components are described herein. In particular, apparatus and methods for performing controlled delivery of multicomponent delivery of biomaterials into or onto a body part, such as a body lumen are described. More specifically, in some embodiments, the apparatus and methods are directed towards controlled delivery of micro-volumes of biomaterials into or onto a target location, the micro-volumes being defined as 0.001 mL-1 mL (or 1 μL-1,000 μL) of volume.
