Abstract: A door lock system may include an outer spindle operatively connected to a disc with a larger diameter than a diameter of the outer spindle. The disc may include an opening that slidingly receives a lock spindle along a lock axis configured to engage a lock body. The lock spindle and the spindle opening may have complementary shapes and sizes such that the lock spindle is rotationally coupled to the disc about the center axis. Torque may be transmitted from a handle to the disc and from the disc to the lock spindle via the opening.

Abstract: A system for intraosseous access can include an elongated instrument that is positioned within a cannula portion of a cannula assembly. The system can include a shield that is coupled with both the elongated instrument and the cannula assembly when in an unlocked state. The shield can permit proximal movement of the elongated instrument relative thereto when in the unlocked state. The shield can automatically transition to a locked state to attach to a distal end of the elongated instrument to restrict access to a distal tip of the elongated instrument.

Abstract: A portable and passive safety intraosseous device to allow for direct introduction of medications, etc., within the intermedullary space of a subject patient's bone or, if needed, the removal of certain substances from such a subject patient's bone. Such a device permits direct drilling and placement of a cannula within the subject bone with access external to the subject patient's skin, permitting, as well, connection of a tube for such introduction/removal purposes. The ability to provide a passive safety unit allows for facilitated utilization in, for instance, emergency situations with the entire device provided for utilization thereof. The device includes a drilling component with a permanently attached stylet and a removable cannula, a power supply for a single drilling operation, a mechanism to draw the stylet back into the drill component after use and disengagement from the cannula, and an automatic closure that activates with the separation of the cannula.

Abstract: A catheter delivery system (10) includes: (i) an introducer sheath (12); (ii) a catheter (14) disposed at least partially within the introducer sheath and movable axial along the introducer sheath; (iii) an invaginating tube (16) sealably secured at or near a first axial end (16a) of the invaginating tube to the introducer sheath at or near a first axial end (12 a) of the introducer sheath; (iv) a runner (28) slidably connected to the catheter; (v) the invaginating tube being sealably secured at or near a second axial end (16b) of the invaginating tube to the runner, such that the runner with inavaginating tube secured thereto is sealably connected to the catheter and movable axially along at least a portion of the catheter; and (vi) means for pressurising the annular space defined between the introducer sheath, the catheter and the invaginating tube.

Abstract: Provided is a bumper capable of improving a maneuvering stability of a vehicle. The bumper is a front bumper 7 to be attached to a front lower portion of a vehicle 1. Flow-straightening protrusions 31 each formed along a vehicular front-rear direction are provided on a lower portion of the front bumper 7 in a way such that they are aligned along a vehicular width direction across a region on an extended line 36 of a vehicular width direction inner end portion 2T of each of front wheels 2L, 2R of the vehicle 1. Thus, the occurrence of turbulent flows around the front wheels 2L, 2R can be restricted so that a vehicle stability can be improved.

Abstract: A portable sampling device includes a sampling housing at least partially enclosing an inner chamber; at least one pumping element disposed within the inner chamber and configured to facilitate airflow through the device; and at least one gas sensor disposed within the inner chamber and configured to detect and/or characterize one or more gases in the airflow.

Abstract: An invaginating device includes an inner elongate member and an outer flexible tube with invaginated axial ends. The outer flexible tube is: disposed at a first axial end of the inner elongate member; concentric with the inner elongate member; sized to provide a radial gap there between; sealably connected at the axial ends of the outer flexible tube to the inner elongate member, with the axial spacing between such sealed axial ends being less than the axial length of the outer tube; and extendable to protrude from the first axial end of the inner elongate member and retractable to reduce such protrusion from the first axial end of the inner elongate member. Fluid contained within the radial gap defined between the inner elongate member and the outer flexible tube is either pressurized or a non-compressible fluid.

Abstract: Optical connection systems including electrical-and-optical connection systems and methods thereof are disclosed. An electrical-and-optical connection system can include an extension tube having a plug and a relay module having a receptacle. The plug can be formed of a metal piece around electrical wires, which, in turn, are around optical-fiber cores that extend along a length of the extension tube. The plug can be configured to pierce through at least a sterile barrier. The relay module can include electrical wires and optical-fiber cores within a housing of the relay module, as well as a receptacle disposed in the housing. The receptacle can be configured to simultaneously accept insertion of the plug therein and establish both electrical and optical connections between the plug and the receptacle from a sterile field to a non-sterile field set up by the sterile barrier. Shape-sensing systems including the optical connection systems are also disclosed.

Abstract: A water treatment system having a base assembly and a treatment assembly. The treatment assembly of the system may be configured to filter particulates from water. The base assembly may include a UV reactor operable to disinfect water for consumption.

Abstract: The anti-back-flow devices and methods prevent fluid from leaking proximally from a catheter, but allow ready access to the catheter using any male luer device. The devices include proximal surfaces that urge open a valve in response to force from a male luer tip. The valves are associated a female luer hub and adapted to function with standard and typical non-standard male luer fittings.

Abstract: Embodiments disclosed herein are directed to a securement device including a retainer defining a channel and at least one mounting wing extending therefrom. The mounting wing extends distally of an insertion site a skin surface adjacent to the insertion site to prevent “rocking” or “pistoning.” The mounting wing further includes channels of reduced thickness configured to impart malleable properties on the mounting wing. This can allow the mounting wing to be shaped to fit different portions of the patient. The retainer further includes various locking and anti-rotational features to guide the catheter into position within the retainer and further prevent “rocking” or “pistoning.” The securement device also includes a protective pad to inhibit abrasions from a medical line, spin nuts, and the like, and includes a clasping feature to retain a portion of the release liner to prevent obstructing ingress/egress of the catheter.

Abstract: A therapeutic back support device including a back support portion that automatically and repeatedly moves forward to maintain engagement with a user's back as the user moves forward with respect to a chair seat. The back support portion substantially resists backward motion and provides substantially continuous therapeutic support to the user's spine pending a release signal.

Abstract: Methods and devices to facilitate positioning of a catheter into a vessel. Devices include axially concentric assemblies of a piercing cannula, a shield and tubing such as a catheter where the shield can be passively or actively locked into position over the cannula tip to prevent inadvertent needle sticks.
