The present invention relates to a sensor configuration () for non-invasive measurement of parameters of a body tissue with a sensor unit () and a sensor mat () for detachable placement of the sensor configuration () on a body surface (). Furthermore the sensor unit () of the sensor configuration () is connectible to a contact head (), which is designed for electrical contacting of the sensor unit () and for supply of light from a light source to the sensor unit (), the sensor unit () being designed as a flexible printed circuit board with optical components, at least comprising a light detector device (), in order to detect light that is emitted into the body tissue and has passed through the latter, a first contact means () and conducting tracks () for operative connection of the sensor unit () to the contact head (). The sensor mat () of the sensor configuration () has a multi-layered structure, with a lower layer (), which has a lower contact surface for contact on the body surface () and an upper contact surface for contact of the sensor unit (), whereby openings () are provided which are aligned with the optical components of the sensor unit (), and form an optical passage, and with an upper layer (), which is connected to the upper contact surface of the lower layer () in a way detachable from one another.

Sensor configuration

A measurement system and method for measuring at least one parameter in a body tissue comprise at least one measurement device to be applied to the body, an optical unit for emitting light waves, wherein at least one wavelength of the light waves lies in the region of the absorption of a body parameter, at least one light guide between the optical unit and the measurement device in order to transmit light waves, and an evaluation unit for evaluating measurement waves. Light waves emitted by the optical unit can be beamed into an optical measurement volume in the body tissue by means of the measurement device, and measurement waves received by the measurement device from the measurement volume can be transmitted from the body tissue to the evaluation unit. The evaluation unit comprises a transformation algorithm, which transforms pulsatility of a body parameter measured in the measurement volume into a parameter of the pressure in the body tissue, wherein the body parameter is measured by determining the absorption of the light waves.

Measurement system and method for measuring parameters in a body tissue

The invention relates to a device and a method for noninvasive measurement of parameters of a bodily tissue, the measuring device having a sensor unit and a sensor mat for detachable placement of the device on a body surface. The sensor unit () has a receptacle (), the interior of which accommodates a sensor arrangement, wherein the receptacle () has a sensor surface () in the direction of the body surface. The sensor mat () has a cutout () for accommodating the sensor unit () and a contact surface (), at least partially surrounding the sensor unit (), for placement on the body surface (). A cover () is provided for closing the cutout () over an upper side of the sensor unit () and the sensor mat () during a measurement of parameters. The sensor unit (), the sensor mat () and the cover () are detachable from one another.

Measuring device for determining cerebral parameters

The invention relates to a measuring device and to a method for measuring parameters of a body tissue using an elongate probe () for insertion into the body tissue, comprising at least one optical waveguide () for transmitting light beams that runs along the longitudinal axis of the probe within the probe, an exit region () from which light beams emitted from the optical waveguide exit into the body tissue, and at least one receiving region () through which light beams reflected and/or scattered in the body tissue enter the probe as input light beams on a photodetector or in an optical waveguide (). The exit region () is provided at the distal end of the probe () and is oriented at least partially in the longitudinal direction of the probe (). At least some of the emitted light beams exit the probe in the longitudinal direction of the probe. The at least one receiving region () is located at a distance from the distal end of the probe on a lateral circumferential region of the probe. The input light beams entering a receiving region () are subject to a deflection of more than 90&#xb0; relative to the light beams emitted from the exit region ().

Measuring device for measuring cerebral parameters

The invention concerns a method and an apparatus for mechanical stimulation in vitro of tissue, wherein tissue patches () are retained in a tissue carrier (), thereby presenting first surfaces () to be stimulated in a plane (X) and wherein a roller () having a second surface () arranged at its periphery is moved parallel to said plane (X), thereby imposing selected forces on said first surfaces () by said second surface () for stimulating the tissue patches (). By presenting the surfaces () to be stimulated in a common plane (X) and by moving the roller () parallel to said common plane (X) of the first surfaces (), serving several tissue carriers () with one roller () is made easy, thus integration into an industrial production is made practicable.
