A tubing connection adaptor system is provided. The system includes a male connector body having a first end opposite a second end and a female connector body having a front end opposite a rear end. The front end of the female connector body is dimensioned to operably engage the first end of the male connector body therein, such that a continuous channel is defined through the male connector body and the female connector body upon engagement therebetween. A tab extends from the first end of the male connector body, wherein the tab frictionally engages a notch disposed through the front end of the female connector body.

The adapter includes a housing and a filling nozzle provided in communication with a containing portion in the housing and coming into contact with an end surface of the injection device, in which the injection port of the injection nozzle is formed, when the housing is attached to the injection device. An open end of the filling nozzle is set to be smaller than an inner diameter of the containing portion and larger than the injection port. Of an internal space of the housing from a partial region of the containing portion to the open end, at least a predetermined space being continuous and including the partial region is formed in a manner where an inner diameter of the predetermined space decreases toward a side of the open end. According to this configuration, the injection fluid can be suitably transferred from the outside to a needleless injector.

Treatment delivery apparatuses include a treatment administration device, a multi-lumen catheter reversibly couplable with the treatment administration device, and a controller. The treatment administration device has a housing cartridge-pump interfaces disposed within the housing, each cartridge-pump interface being reversibly couplable with a medication cartridge type. The treatment administration device further includes pumps disposed within the housing, each pump being in fluidic connection with at least one cartridge-pump interface. The controller enables the treatment administration device to: receive a treatment selection, determine available medications based upon medication cartridges coupled with the cartridge-pump interfaces, and administer a treatment to the multi-lumen catheter, based at least upon the treatment selection.

A connector is used to connect a gases supply to a user. The user can be fitted with an interface, such as a cannula, while the gases supply can include a conduit. The connector interfaces between the conduit and the interface. The connector has a female assembly and a male assembly that connect together, such as by push fit. The male assembly includes an inner portion sized and configured to mate with a first female connector and an outer portion sized and configured to alternatively mate with a second female connector.

A luer connection device is disclosed having a housing including a side wall having an inside surface defining a lumen with a central axis, an proximal end, and a distal end including a male luer tip within the lumen having a central flow diverter extending outwardly from the central axis to direct a fluid to a circumferential dead space distal to the male luer tip. A luer connection device is also disclosed having a flow expansion channel disposed in the lumen tapering outward from the wall of tubular housing and partially extending along a longitudinal axis from the tip opening toward the base opening for increasing mixing and flow through a circumferential dead space in the fluid path distal to the male luer tip.

A catheter system may include a luer adapter, which may include an outer surface having threading or a recess. The catheter system may also include a flow control plug, which may include a proximal end and a distal end. The proximal end of the flow control plug may include a filter element permeable to air and not to blood. The distal end of the flow control plug may include a cylinder and a taper-shaped luer tip spaced apart from the cylinder. An inner surface of the cylinder may include a protrusion engaged in a snap-fit with the recess or corresponding threading mated with the threading.

A catheter priming apparatus may include a barrier forming a reservoir. Fluid may be disposed within the reservoir. A support structure may be disposed within the barrier. The support structure may include an opening extending through the support structure and a connector configured to couple the catheter priming apparatus to a catheter system. A one-way valve may be coupled to the support structure and configured to allow the fluid to flow out of the reservoir through the connector in response to compression of a portion of the barrier aligned with the opening.

A device for filling a reservoir. The device includes a cover portion comprising a septum window, and a bottom portion, the bottom portion configured to attach to a disposable housing assembly comprising the reservoir, wherein the cover portion and the bottom portion are rotatably attached in a locked configuration and wherein in a locked configuration, a septum is obscured through the septum window, wherein when the cover portion and the bottom portion are placed in an unlocked configuration, the cover portion rotates with respect to the bottom portion and the septum is visible through the septum window.

A gas measurement adapter includes a flow tube portion configured to allow gas to pass through the flow tube portion and a window portion configured to allow measurement light for measuring a component of the gas passing through the flow tube portion to pass through the window portion. The adapter is prepared by using an adapter forming material containing a cycloolefin-based resin as a main component.

A morselizer comprising (a) a hollow cylindrical structure with an inner wall and an outer wall and comprising a first end section, a second end section, and a center section extending axially between the first end section and the second end section providing a substantially axial liquid pathway therein; (b) wherein each end section comprises a axially and radially hollow luer fitting that is attachable to a structure with a complementarily sized luer fitting; and (c) one or more blades extending transversally across the inner diameter of the center section wherein (i) each blade is comprised of a plurality of ends, including a posterior end secured to at least the center wall section inner wall at a center section inner wall first position and an anterior end proximal a center section inner wall second position opposite the center section inner wall first position, with a gap positioned between the blade anterior end and the center section inner wall second position, and (ii) at least two ends comprise cutting ends.
