A breath test system is provided comprising a sensor unit configured to sense the presence or concentration of a volatile substance present in air flowing through a predefined inlet area, and generate a signal corresponding to the concentration of said substance. Also provided is an apparatus configured to detect the presence of a person in the vicinity of said input area, and registering said presence, and configured to respond by delivering an output. This apparatus includes a unit configured to call for immediate attention of said person, and upon registration of the presence of said person, provide instructions to said person to direct an expiratory air flow towards said inlet area. An analyzer to determine breath substance concentration of said person is also provided, the determination based on said signal corresponding to the substance concentration.

Breath test system

A wheel assembly comprising a wheelchair wheel () and a backstop arrangement () configured to selectively engage and disengage a backstop function and comprising a backstop selector () and a backstop member (), wherein the wheel () comprises an internal-gear wheel hub () comprising a number of internal gears () and having an inner rotatable circumferential surface (), and wherein the backstop member is configured to allow the inner circumferential surface to rotate in one direction and to prevent rotation in the opposite direction. The wheel assembly comprises further a gear-shift arrangement comprising a shift member (), which is axially moveable within the internal-gear hub () to engage a specific gear of said number of internal gears (), and wherein the shift member () via a connector member () is operatively connected to the backstop selector.

A system for authorization control and breath testing, comprising a management system unit and an authorization control and breath testing unit, wherein the authorization control and breath testing unit is configured to grant authorization to an individual seeking authorization without having access to any personal identification information about that individual.

System for authorization control and breath testing

Embodiments herein relate to a wheelchair gearshift arrangement (), which comprises an axle tube () and a pair of wheel attachment adaptors () inserted into a respective end () of the axle tube (). The wheel attachment adaptors () further includes a respective axle sleeve () adapted to receive and hold a respective wheel axle () of a respective complete wheelchair wheel (). Each complete wheelchair wheel () having a respective wheel axle centric, axially translatable, gear change mechanism (). One or more gear change actuators () are arranged within the axle tube () such that they are operative to selectively, upon user manipulation of an associated gear selector (), axially translate the associated gear change mechanisms () of the respective complete wheelchair wheels (). Such translation will affect a change of gear ratio between a push-rim () and wheel-rim () of each respective complete wheelchair wheel ().

The invention relates to a medical sealing device () for the sealing of a puncture hole in a vessel wall, and comprises an inner member (), which is adapted to be positioned at an interior surface of the vessel wall, and an outer member (), which is adapted to be positioned outside the vessel wall, the inner member () and the outer member () being held together by a retaining member (), wherein at least one of said inner member (), outer member () and retaining member () is made from at least one shape memory polymer.

Medical sealing device

The present invention provides a dissolvable medical sealing device () for closing a wound in vessel. A sealing device () according to the invention is made of a material that dissolves by means of physical processes, rather than by means of chemical or biological processes. Such a sealing device () can be made of polyethylene glycol, polypropylene glycol, copolymers containing ethylene glycol and propylene glycol, polyvinyl alcohol or polyvinyl pyrolidone, or any combinations thereof.

Erodible vessel sealing device without chemical or biological degradation

The invention provides a method for replacing a first introducer, whose distal end is inside a vessel and whose proximal end is outside the skin of a patient, with a second introducer. The method comprises the steps of inserting a guide rod into the first introducer, removing the first introducer, passing the second introducer over the guide rod, and removing the guide rod. The guide rod to be used according to the method has preferably a flexible distal portion with a blunt distal end and a stiff proximal portion with a tapered proximal end.

Guide rod for introducer replacement

The present invention relates to a measuring device, insertable into a living body. The device includes an elongated flexible member in the form of a thick-walled hollow tube with a proximal end and a distal end. The tube defines a central lumen with an inner wall. The lumen may contain a core and an insulating material provided between the core and the inner wall. The core may be made of an electrically conductive material and may be of essentially constant diameter over its entire length. Alternatively, the lumen may contain at least two electrical leads. An electrical sensor is attached to the distal end of the elongated flexible member and is electrically connected to the core.

An indicator device for visually indicating a pressure of blood inside a blood vessel includes: a body, the body comprising a duct extending in the body and having a sealed proximal end; a distal end portion adapted to be positioned inside the blood vessel and including a liquid inlet opening in fluid communication with the duct; and a window including an at least semi-transparent section configured to enable visual observation of blood entering into the duct via the inlet opening when the inlet opening is located inside the blood vessel.

Device for visually indicating a blood pressure

The present invention relates to a sensor assembly arranged to be disposed in a body for measuring a physiological variable. A basic idea of the present invention is to provide a sensor and guide wire assembly which communicates with an external unit by an inductive coupling between a first coil provided in the sensor assembly and a second, external coil which is disposed in or connected to the external unit. The external unit is preferably the same unit that is used to numerically or graphically display the physiological variables that are measured with the sensor and guide wire assembly. With the terminology introduced above, it should here be clear that both the signal transfer from the sensor as well as the energy feeding from the external unit to the sensor may be accomplished through the inductive coupling between the first and second coils.
