Abstract
A pressure measurement device for measuring pressure and/or for measuring elasticity of a vein, an organ or a compartment of a body in combination with an ultrasound measurement unit. A pressure sensor is configured as a thin film pressure sensor with the speciality that the intermediate space, between the films of the film pressure sensor, is filled with an ultrasound-transparent and electrolytically/electrically inactive liquid. The films of the film pressure sensor are fabricated from an ultrasound-transparent material.
Core Innovation
The invention relates to pressure measurements according to the Baumann concept, combining ultrasound observation with a thin film pressure sensor for measuring pressure and/or elasticity of veins, organs, or anatomical compartments. A pressure measurement device is provided for use in combination with an ultrasound measurement unit.
The pressure sensor is configured as a film pressure sensor having films with an intermediate space between the films. The intermediate space is filled with an ultrasound-transparent and electrolytically/electrically inactive liquid, so that ultrasound transmission is enabled through the sensor structure.
The films of the film pressure sensor are fabricated from an ultrasound-transparent material, at least in some regions of said material. The concept further includes ultrasound measurement and automated ultrasound image processing to identify vein collapse time and measurement start and to evaluate measurement quality.
The overall arrangement is used for non-invasive measurement goals associated with compartment syndrome, intracranial pressure via a newborn fontanelle or via the internal jugular vein, and ocular pressure via a closed eyelid.
Claims Coverage
The independent claim set is centered on a pressure measurement device for measuring pressure and/or elasticity of a vein, organ, or compartment in combination with an ultrasound measurement unit, with three main inventive elements: the film pressure sensor, the ultrasound-transparent electrolytically/electrically inactive liquid in the intermediate space, and ultrasound-transparent sensor films.
Film pressure sensor with ultrasound-transparent intermediate-liquid
A pressure sensor configured as a film pressure sensor is provided, wherein an intermediate space between films of the film pressure sensor is filled with an ultrasound-transparent and electrolytically/electrically inactive liquid.
Ultrasound-transparent sensor films
The films of the film pressure sensor are fabricated from an ultrasound-transparent material, at least in some regions of said material.
Ultrasound measurement unit combination for vein/organ/compartment elasticity
A pressure measurement device measures pressure and/or elasticity of a vein, an organ or a compartment and is for combination with an ultrasound measurement unit.
The claims cover a non-invasive ultrasound-combined pressure measurement arrangement using a film pressure sensor with ultrasound-transparent, electrolytically/electrically inactive liquid in the intermediate space and ultrasound-transparent films, for measuring pressure and/or elasticity of a vein, organ, or compartment.
Stated Advantages
Non-invasive clinical measurement goals are described for pressure and/or elasticity measurements (e.g., for compartment syndrome, intracranial pressure, and ocular pressure).
Documented Applications
Measuring pressure/elasticity associated with compartment syndrome.
Measuring intracranial pressure via a newborn fontanelle or via the internal jugular vein.
Measuring ocular pressure via a closed eyelid.
