A modular medical device catheter including a parent module and an adapter module. An attachment mechanism couples the adapter module to a surface of an inner lumen of the parent module. The attachment mechanism includes a coil in which a surface of the coil directly engages with the surface of the lumen of the parent module. The adapter module can include an elongated element having one or more electrical conductors.

A capnography system includes a CO.sub.2 sensing system having a CO.sub.2 sensor configured to measure a CO.sub.2 concentration in exhaled breath of a subject, a processor configured to derive one or more breath related parameters based on the measured CO.sub.2 concentration, and a communication unit. The capnography system includes a tubing system configured to allow flow of respiratory gasses therethrough. The tubing system includes a connector configured to connect the tubing system to the CO.sub.2 sensing system and a communication component configured to provide an indication of a type of the tubing system to the communication unit. The communication unit is configured to transfer data to the processor based on the indication obtained from the communication component, and the processor is configured to change or suggest a change of an operation mode of the CO.sub.2 sensing system based on the data.

Methods and systems provide provides a vacuum surge protection system or an Anti-Vacuum Surge (AVS) module and a console-side connector that form an energy (power) and/or data transfer system, which passes the energy and/or data using a magnetic field, via non-contact magnetic induction, between the console-side connector and the AVS module. The AVS module typically powers a medical tool, such as a phacoemulsification handpiece, for ophthalmic procedures, such as cataract removal.

A circuit connector for a humidification system, the system comprising a base unit configured to be engaged by a humidification chamber. The circuit connector comprises an inlet to fluidly connect to an outlet of the humidification chamber to receive humidified gases therefrom, an outlet to sealably connect to or integral with a conduit for directing the humidified gases to a user, and an electrical terminal for electrically coupling the circuit connector to an electrical terminal associated with the base unit. The circuit connector may be releasably and lockably connectable to the outlet of the humidification chamber and/or orientation features may control orientation of component parts of the system as they are assembled.

A blower unit for use as part of an integrated blower/humidification system is described. The blower unit has an outer casing, which encloses and forms part of the blower unit, the casing including an air inlet vent. The blower unit further includes a humidifier compartment for receiving a humidifier unit with a separate gases inlet and outlet, the compartment having a heater base for heating the contents of the humidifier unit. The compartment also has a blower inlet port which aligns with the humidifier unit inlet in use, the blower providing a gases path through the casing between the inlet vent and the inlet port. The blower unit also includes a fan for providing a pressurised gases stream along the gases path, and a power supply unit for powering the fan. The gases path is routed over the power supply unit in order to provide a cooling air flow.

A connecting piece having a transfer apparatus for data transfer and/or for transferring electrical energy with the counter connecting piece. A connecting piece of this type is preferably used in an intelligent medical fluid conduction and transfer system, in which various components are interconnected by means of the connecting pieces not only fluidically but also for the purpose of transferring energy and/or data with each other, such that, for example, information regarding the medication can be exchanged or validated.

A threaded fluidic fitting may include a fluid passage, at least one fluid port, a threaded fitting portion, an engageable body portion, and an electro-fluidic leak detection element. The fluid passage extends from the fluid port of the threaded fluidic fitting. The threaded fitting portion comprises a helical thread, extends from a leak detection face of the engageable body portion, and is configured to rotate with the engageable body portion to enhance a fluidically sealed engagement of one of the fluid ports with a complementary fluidic component. The electro-fluidic leak detection element is positioned on the leak detection face of the engageable body portion or on a drip edge portion of a face extending from the leak detection face. A fluid handling system may include a plurality of threaded fluidic fittings and a leak detecting computing hub in communication with the plurality of threaded fluidic fittings.

A powered catheter and/or powered catheter system is described. The catheter includes a catheter hub with one set of contact components that are configured to connect to a mating cable with a corresponding second set of contact components. The mating cable can be part of another device, such as a controller or power source.

A tube and connector assembly for warming an intravenous fluid comprises a tube, a temperature sensor, and a connector. The tube includes a single hollow generally cylindrical side wall with an inner surface along which the intravenous fluid flows. The tube further includes first and second electrically conductive wires, each within the side wall and electrically connected to one another to carry electrical current to warm the intravenous fluid. The temperature sensor is configured to measure a temperature of the fluid flowing through the tube. The connector includes first, second, and third side walls. The first side wall receives the tube. The second side wall is positioned opposite the first side wall and is configured to receive line tubing. The third side wall is spaced apart from the second side wall and includes threads on an inner surface thereof configured to receive a line connector for the intravenous line.

The disclosure relates to medical tubes and methods of manufacturing medical tubes. The tube may be a composite structure made of two or more distinct components that are spirally wound to form an elongate tube. For example, one of the components may be a spirally wound elongate hollow body, and the other component may be an elongate structural component also spirally wound between turns of the spirally wound hollow body The tube need not be made from distinct components, however. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or may be employed for other medical uses.
