Abstract: A gas flow reversing element is provided comprising a main piece defining at least one closable outlet opening, a branching piece extending from the main piece, a line connector connected to the distal end of the branching piece, a pressure connector connected to the main piece, the pressure connector being structured to be fluidly connected to a pressurized gas supply; and a nozzle being configured and arranged in the main piece in such a way that a gas flow flowing in the main piece from the pressure connector through the nozzle to the at least one outlet opening, with the at least one outlet opening being disposed in the second open position, a gas flow can also be generated in the branching piece in a direction toward the at least one outlet opening.

Abstract: The present invention relates to a catheter for ventilating a patient, with a ventilation channel for alternately delivering and removing air and/or oxygen to and from the patient's airways, the catheter having a maximum external diameter of at most 6 mm, mm, and the ventilation channel having an open end, and a connector end for connection to a gas flow reversing element. According to the invention, the catheter is provided with means or elements for measuring the pressure outside the ventilation channel near the open end. The catheter preferably has a pressure measurement channel, with an open measurement end near the open end of the ventilation channel, and a measurement connector piece for connecting a pressure display device. Of particular advantage is a catheter with an expansion body (cuff) that is fluidically connected to a supply channel through which the expansion body can be increased or reduced in size by means of a fluid.

Abstract: A dilator (100) for performing a percutaneous medical procedure, said dilator (100) comprising a proximal shaft portion (112) near a proximal end (114) thereof and a distal portion having a general tapering shape towards a distal end (120) of said dilator (100), said distal portion being adapted for dilation of body tissue. To provide a dilator which can shorten time of procedure a region of an outer surface of said distal portion is provided with a pattern of depressions having a depth in the interval of 0.1 to 3 mm.

Abstract: A nebulizer uses air or preferably oxygen to aerate and transport an anesthetic for providing topical anesthesia to the airway passages of a patient undergoing analysis or treatment by any of several medical instruments used to traverse the airway passages. The nebulizer is preferably applied in connection with fiberoptical diagnostic and therapeutic instruments, such as bronchoscopes, endoscopes and laryngoscopes, and many variations of these instruments. Other liquid, aerosol, and gaseous drugs may also be administered with the nebulizer.

Abstract: The invention concerns a one-person-operable, sterilisable, medical pressure measuring apparatus (1: 6: 8: 11: 12: 23: 31), in particular for blood pressure measurement, wherein the pressure measuring apparatus (1: 8: 11: 12: 23: 31) has least one cannula connection (26), a measuring duct (4) and an entry (27). The measuring duct (4) opens into a closed container (2) with rigid walls (7), a compressible medium (3) being disposed in the container (2). The pressure measuring apparatus (1: 6: 3: 11: 12: 23: 31), besides the measurement of the pressure in a vessel, permits contamination-free insertion of a catheter, preferably for monitoring the position of a cannula (24). Unnecessary injury to vessels can be avoided thereby and complications upon the insertion of catheters can be considerably reduced.

Abstract: A process and a device for pressure controlled manipulation of a fluid (4a), in particular for medicinal applications. The device comprises a receptacle (1a) of variable volume to contain the fluid (4a), a pressure creation device (2a) for producing pressure on the fluid (4a), an opening (1c) for admitting and/or discharging to fluid (4a), a measuring channel (2e) of prescribed cross-section connected to the receptacle (1a), and a buffer (2d) of prescribed volume which communicates with the measuring channel (2e), the measuring channel (2e) and the buffer (2d) being filled with a compressible medium. The pressure creation device is preferably a piston (2a) which can be pushed into the receptacle (1a), the piston being sealed to the inner wall of the receptacle (1a) by a sealing means (2c).
