Abstract: A device (1) for performing ultrasonic examinations and pressure measurements comprises an ultrasonic transducer (60), a pressure sensor (50), a housing (10) to accommodate the ultrasonic transducer (60) and the pressure sensor (50), a support plate (40) arranged in the housing (10) and a flexible membrane (21) arranged on the end face of the housing. A sealed chamber (47) for receiving a liquid medium is formed between the membrane (21) and the support plate (40), and the ultrasonic transducer (60) and the pressure sensor (50) are arranged on the support plate (40) in such a way that a first transmission surface of the ultrasonic transducer (60) and a second transmission surface of the pressure sensor (50) are directed towards the chamber (47).

Abstract: The invention relates to a method for measuring an internal pressure (ICP1, ICP2) of a compartment, in particular a muscle compartment, in which an ultrasonic measuring unit coupled to a pressure measuring device is placed on a tissue under which the compartment to be measured is located and a pressure is increased on the tissue by exerting a force. In order to be able to perform a fast and inexpensive, non-invasive measurement of the pressure within a compartment, in particular a muscle lodge (so-called lodge syndrome), it is proposed that the internal pressure (ICP1, ICP2) is determined from a change? p in the pressure p acting on the compartment and a change? E in an extension E(p) of the compartment that occurs during the action of the pressure p.

Abstract: A replaceable attachment for an ultrasound probe includes a ring-like fastening region for fastening the attachment to the ultrasound probe, and a flexible membrane arranged on the fastening region. A first liquid or gel-like contact medium is applied to an inner contact surface of the membrane. The contact surface makes contact with an end face of the ultrasound probe when an attachment is fastened to the ultrasound probe. Before the attachment is fastened, the first contact medium is distributed on the contact surface in such a manner that, in an array region of the contact surface, a quantity of the first contact medium per surface is at least twice as large as in a remaining region of the contact surface. A positioning and extent of the array region is adapted to a positioning and extent of a piezo array of the ultrasound probe.

Abstract: A method for determining intracranial pressure of a patient comprises the steps of ultrasound imaging of a central retinal vein (14) supplying a retina of an eye (10) of the patient, for generating ultrasound images, exerting a varying external pressure on the eye (10), identifying a collapse and/or an occlusion of the central retinal vein (14) based on the ultrasound images, correlating a value of the external pressure to the collapse and/or occlusion, and determining the intracranial pressure based on the correlated external pressure value. A device (1) for determining intracranial pressure of a patient comprises an ultrasonic transducer, a pressure sensor and a housing (2) to accommodate the ultrasonic transducer and the pressure sensor. The housing (2) features a face being adapted to contact an eye lid (11) and/or eye ball (13) of the patient in order to exert external pressure on the eye (10), wherein ultrasonic radiation from and to the transducer is transmitted through the face of the housing (2).

Abstract: In a method for the non-invasive capture of a temporal development of a state of a tissue structure, first measurement data of the body region (1) are recorded non-invasively and first image data are generated from the recorded measurement data. This first image data is pre-processed locally with the aid of a first local terminal device (100.1) and transmitted together with first identification data from the first local terminal device (100.1) to a server (10) for storage. At a later time, image data stored using second identification data is retrieved from the server (10) and displayed on the second local terminal device (100.2). This is followed by a non-invasive recording of second measurement data of the body region (1) to generate second image data.

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.
