Transcutaneous devices which provide wireless communication between a sensor and an external device are also disclosed.

Accessories for an angle grinder include a disposable rotary sanding disk having quite large shaped ventilating / viewing apertures, for use with a resilient backing plate also having shaped ventilating apertures. The apertures of one or both parts are shaped so that snagging of the apertures on projections from the work surface is minimized and to facilitate air flow across the work surface during use. This air flow helps in cooling the work and ejecting detritus, so minimising clogging effects. The ventilating apertures also facilitate viewing the work to be sanded through the spinning disk during the abrasion process, so that operator feedback is immediate. The holes also give the sanding disk more resilience so that a greater area comes in contact with the work and the disk wears more evenly over its abrasive surface.

An impact absorber employs dilatant (shear responsive) fluid that is subjected to a controlled, low amplitude, high frequency oscillatory stress which controls the stiffness of the fluid. Piezoelectric transducers, voice coils, and other forms of transducers may be used to apply controlled vibratory stress to the fluid. The energy absorber may be used in protective body armor, medical devices such as splints and casts, vehicle safety absorbers and many other products which benefit from ability to control the stiffness of the energy absorber.

A personal protection device can be used to protect individuals from falls. The device can be linked to a mechanical or electrical device, which triggers deployment of the device when the individual accelerates vertically. In this manner, a falling individual's injuries such as hip fractures, upper extremity injuries, and head injuries are minimized by the mediated gradual deceleration of the wearer of the device. The device allows mobility of the individual, because it is worn in a non-deployed compact form within a wearable article of clothing or belt. The device may also be used to protect non-ambulatory individuals who sustain falls from a bed or chair.

An optical coherence tomography probe and laser combination device configured for real-time z-directional guidance of the incisional depth of a surgical procedure. It can be used alone or placed within the working channel of an endoscope. The device includes an OCT single mode fiber, and a laser fiber or laser hollow waveguide or electrical surgical wire positioned adjacent to the OCT single mode fiber. The single mode fiber is configured to move laterally when activated by an actuator to scan light data reflected from a sample that is positioned in front of a distal end of the device. The light data can be processed to generate a B-scan image. The device can collect data in real-time during lasing, or immediately prior to and following the cutting. The surgical tool, when coupled to a processor, can deactivate when the B-scan image identifies that the incision is within a predefined tolerance.

The invention relates to a finger guard (7) for an injection device for administering a dose of a liquid medicament (M), the finger guard (7) comprising two inwardly biased spring arms (8) arranged for bearing against a protective needle shield (5) arrangeable at a hollow needle (4), the finger guard (7) further having a respective locking arm (9) assigned to each spring arm (8) biased in a distal direction (D) thus bearing against the respective spring arm (8) when the protective needle shield (5) is in place, wherein the spring arms (8) are arranged to move inwards when the protective needle shield (5) is removed thus allowing the locking arms (9) to move distally into a position where they prevent the spring arms (8) from being pushed outward again.

A manually directed, electronic multi-channel pipettor uses servo controlled motors to drive a carriage and pipetting head in response to a user's manipulation of a control handle. The pipetting head include an array of tip fittings, e.g. 96. The system includes a check processor to avoid unintended motion in case of system faults or crashes. The system requires substantial force to attach the array of tips, and therefore includes controls that require both of the user's hands be occupied during the tip attachment process.

This invention relates to a safety needle to prevent needle stick injuries. The invention provides a safety needle accessory comprising a hollow needle having a base end and a sharp end, a hub surrounding the base end of the needle and having a connector for connection to an injection device, a sleeve surrounding the hub and slidable relative to the hub in an axial direction, an elastically deformable member, and a pack having a closed end covering the sharp end of the needle and an open end exposing the connector of the hub and which is releasably mounted over the needle, hub and sleeve. The sleeve is slidable in a first axial direction from a first position in which the needle is fully or partially covered by the sleeve to a second position in which the needle is exposed, via an intermediate position between the first and second positions in which the sharp end of the needle projects from the sleeve, and in a second axial direction from the second position to a third position in which the needle is fully covered by the sleeve. The deformable member is deformed by the sleeve sliding from the first to the second position and the force for sliding from the second to the third position is provided by the stored elastic energy in the deformable member. The closed end of the pack has a removable cap at a position on the pack such that removal of the cap exposes the sharp end of the needle but not the sleeve when the sleeve is in the intermediate position.

The invention is a portable, non-pressurized oxygen generation device. A first chamber holds an oxygen liberating chemical, and a catalyst from a second chamber begins the oxygen liberating reaction when the two chemicals mix.

A protective foot cover for use in dance, exercise, or athletic applications using strategically placed thicker protective pieces in ball and toe areas of the foot in connection with an elastic material in the sole structure to allow the foot to move freely and provide less of a barrier between the foot and floor such that a dancer can better sense the floor upon which they dance. The foot cover incorporates strategically placed protective patches that provide support, protection, and comfort to the ball and toe portions of the foot. The patches are spaced from one another so that the footwear is able to move more naturally with the expansion of the foot as pressure is applied to the foot. The foot cover may be used alone, whereby the toe and heel portions of the foot are exposed, or in combination with a dance shoe providing a stretchable sole running from the arch portion to the toe portion of the foot.
