Abstract: The invention concerns a combination of a microscope with a measurement device, in particular a diagnostic device, that is usable during an operation on or examination of a specimen performed with the microscope. During the operation or examination, specimen data that are ascertained or determined by the measurement device are directly displayable in the microscope as an optical signal. In the event the measured data of the specimen exceed or fall below threshold values and/or interval values, a warning signal is triggerable by way of which further actions, such as shutdown or switchover actions, can be automatically executed as applicable.

Abstract: An emergency medical treatment system that uses medical information recorded in a user file by a central computer connected to a wide area network. The system is designed to be used with a recording and monitoring health and physical fitness system that automatically sends the parameter information from a sensor worn by a subscriber to a central computer. The wireless communication unit is able to connect to a wireless communication network which, in turn, connects to a wide area network. A central computer is connected to a wide area network that is able to continuously download the physiological parameter information from the wireless communication unit via the wireless communication network. The central computer uses a health information recording software program to create a continuously updated subscriber's medical database containing current and historical medical information.

A bolus of the particulate material is injected into the tissue area to structurally stiffen the tissue.

Abstract: A therapeutic agent is incorporated into microbubbles of a contrast agent, and the microbubbles containing the therapeutic agent are delivered to a region of interest in a patient. An ultrasound image of the region of interest is generated by an ultrasound imaging system, and ultrasound energy for destroying the microbubbles of the contrast agent is transmitted to the region of interest. Parameter data that is representative of activation of the therapeutic agent in the region of interest is acquired, and a parameter display is generated. One or more parameters of the ultrasound energy applied to the region of interest for activating the therapeutic agent may be adjusted, either manually based on the parameter display or automatically based on acquired parameter data. In one embodiment, the parameter display is indicative of a parameter associated with the ultrasound energy transmitted to the region of interest.

Abstract: A container has an upper fluid receiving portion and a lower fluid discharge portion which is closed off at its bottom by a closure. In carrying out the method of the invention, a blood sampling from the umbilical cord of a newly born infant is taken by first clamping off a section of the cord. The clamped section is then separated from the main portion of the cord and deposited into the container. One of the clamps is then removed to permit the blood in the cord section to drain into the container. The drained blood is then transferred to a second container, which may comprise a test tube or syringe, through the fluid discharge portion of the container, this being achieved by either causing a needle attached to the container and sealed with a needle cover to penetrate the needle cover as well as the test tube cover, penetrating the closure with a needle if it be a diaphragm or the like or opening a valve at such closure by a mechanical actuation with the nose of a syringe.
