A respiratory mask for use with a patient, and that is suited for use with children, includes a flexible cushion arranged to interface with and deliver air to the patient's nose. The cushion has a tube connection portion at one or both sides adjacent the patient's nares, the tube connection portion being arranged to connect to an air delivery tube. This location, plus the very low profile of the mask, allows a patient (e.g. an infant) to sleep on their face more comfortably. A more rigid support structure adjacent the cushion is provided to stabilize the cushion and prevent it from collapsing. Headgear is also provided and arranged for releasable attachment to the support structure.

A blood withdrawal system for producing blood from a body part for diagnostic purposes, comprising a housing with a lancet guide capable of guiding a lancet on a predetermined puncturing path and a lancet drive for driving a puncturing movement of a lancet on the predetermined path. The lancet drive comprises a drive rotor driven by a drive spring and rotates about an axis during the puncturing movement, and a coupling mechanism which converts the rotational movement of the drive rotor into a puncturing movement, wherein the lancet is moved during a forward phase of the puncturing movement in the puncturing direction until its tip penetrates into the body part to create a wound and is retracted from the skin during a retraction phase of the puncturing movement. The coupling mechanism includes a translation element coupled to the lancet and guided by a guide on a movement path.

A method of deploying multiple stents using a multiple stent delivery system includes moving a distal stent into contact with a stent-holding surface of a compressible expanded tip of an inner member. A sheath is retracted relative to the inner member to deploy the distal stent by holding the distal stent stationary with the inner member and retracting the sheath. The sheath is advanced relative to the inner member to reposition a proximal stent to capture, be positioned behind a next stent to be deployed by being compressed and passing the compressible expanded tip through the next proximal stent. The sheath is retracted relative to the inner member to bring the next stent to a pre-deployment position and then deployment of the next proximal stent can take place as already performed for the first deployed stent.

Receiver apparatus for use with an analyte sensor, and methods of operation and manufacturing. In one embodiment, the analyte sensor is an implanted/implantable blood glucose sensor, including oxygen-based detector elements. The receiver apparatus is a wireless-enabled small form-factor device with limited functionality that can be easily worn or kept with the user on a continual basis, thereby obviating the need for a more fully featured receiver or smartphone for extended periods of time (e.g., one week). The exemplary oxygen based analyte sensor, with high degree of stability over time, enables the user to divorce themselves from the more fully functioned receiver or smartphone, since no external calibration of the sensor is required during the extended period. In one variant, the device is a lightweight wristband. Other variants include e.g., pendants, finger-worn rings, arm or head bands, skin patches, and even dental, subcutaneous, or prosthetic implants.

In a motor-vehicle drive train containing a differential, which has an differential input part and two differential output parts, a friction clutch with a limited transmittable torque is arranged between two of the differential parts, so that, with a small predetermined difference in torque between the two coupled differential parts, said friction clutch can slip to accommodate torque shocks. A temperature-dependent adjusting means is provided, which reduces the clutch engagement pressure with increasing clutch temperature.

A ball endmill includes a cylindrical tool body that is to be rotated about its axis, ball-nosed end cutting edges located in an axially distal end portion of the tool body and describing a semi-spherical-shaped locus during rotation of the tool body, and spiral gashes located in the axially distal end portion of the tool body and defining rake faces of the respective ball-nosed end cutting edges. The tool body is made, at least at its part providing each ball-nosed end cutting edge, of a hard sintered body. Each ball-nosed end cutting edge is inclined with respect to the axis by a helix angle in a range from about 10° to about 30°. The tool body has, in its distal end, a non-gashed central area in which the spiral gashes do not exist. A ratio of a size of the non-gashed central area to a ball nose radius is in a range from about 0.03 to about 0.1.

It is an object of the present invention to increase durability of a driving tool. A representative driving tool comprises an elongated operating member that drives in a driving material and a drive mechanism that drives the operating member. The drive mechanism comprises a rotating flywheel and the flywheel includes an inner wheel and an outer wheel which are concentrically disposed to each other. The inner circumferential surface of the outer wheel is fitted on an outer circumferential surface of the inner wheel. The outer circumferential surface of the outer wheel directly contacts the operating member and thus, the rotational force of the flywheel is transmitted from the inner wheel to the operating member via the outer wheel and the drive mechanism linearly moves. A frictional force between the outer circumferential surface of the inner wheel and the inner circumferential surface of the outer wheel is set to be smaller than a frictional force between the outer circumferential surface of the outer wheel and the operating member. With such construction, when the operating member contacts the rotating flywheel, slippage is caused between the inner wheel and the outer wheel such that only a smaller frictional force may be produced between the inner wheel and the outer wheel. Therefore, stress which acts upon the inner wheel and the outer wheel can be alleviated and as a result, wear of the flywheel and the operating member can be reduced to increase the durability.

The invention provides an assembly for preparing a medical device, in particular a urinary catheter, by releasing a fluid medium onto the device. The device is packed in a package which contains the fluid medium confined in a compartment. To ensure preparation of the device, the package is adapted to open the compartment and the package in one and the same opening action, preferably so that the compartment opens at the latest when the package opens. In that way, removal of the device from the package requires opening of the compartment and the device is therefore wetted automatically as part of the opening procedure.

A structure is provided that applies support to wiring such as heat trace wiring to the joints and elbows of a marine arm allowing enough flexibility to avoid significant friction in the wiring while accommodating movement of the joints. A removable insulation blanket having internal retention members of wire positioning is wrapped around the joints of the marine arm and the wiring is looped outside the insulation blanket and over the joints to prevent unnecessary friction rubbing of the wiring due to joint movement.
