Abstract: To be able to prevent a situation in which, in percutaneous dilational tracheostomy, the guide catheter already inserted into the trachea can kink, a device for percutaneous dilational tracheostomy is disclosed which has a puncture needle, a guide catheter and a guidewire. The puncture needle has a ground tip at its distal end. The maximum external diameter of the puncture needle is smaller than the minimum internal diameter of the guide catheter, and the puncture needle is insertable so far into the guide catheter that the ground tip of the puncture needle protrudes beyond the distal end of the guide catheter. The maximum diameter of the guidewire is smaller than the minimum internal diameter of the puncture needle, with the result that the guidewire can be guided through the puncture needle such that its end protrudes beyond the ground tip of the puncture needle.

Abstract: The volume of a pressure equalization balloon is connected to a further volume, the pressure of which is intended to remain as constant as possible. To keep the cuff pressure in the pressure range of between roughly 20 mbar and 30 mbar, the equalization balloon is produced from a thermoplastic polymer (TPE) and is overstretched past the maximum intended control volume before first use and is then relaxed to the range of the control volume.

Abstract: A speaking valve for fitment on to a tracheostomy cannula includes a valve unit and an attachment unit. The attachment unit has a tubular housing having a first and a second end and a longitudinal axis extending from the first to the second end. The first end of the attachment unit can be connected to a connector on the tracheostomy cannula and the valve unit is arranged at the second end of the attachment unit. The valve unit and the attachment unit are connected together movably. The valve unit is designed that in a first position it closes the housing of the attachment unit air-tightly with respect to a flow direction, and in at least one second position it permits a flow of air into the housing and out of the housing.

Abstract: The present invention relates to a pressure equalizing device with a pressure equalizing balloon, the volume of which is connected to a further volume, the pressure of which is intended to be kept at as constant a value as possible even in the event of an enforced change in volume.

Abstract: A tracheal tube arrangement includes at least one neck strap including, a deformable material. The tracheal tube arrangement further includes at least one reinforcing member integrated into the neck strap. The reinforcing member includes a first opening for receiving a tie. The reinforcing member further includes at least one reinforcement opening for receiving a portion of the deformable material for bonding the reinforcing member to the neck strap. A method of providing a tracheal tube arrangement that has at least one neck strap is also provided.

Abstract: The present invention concerns a tracheostomy cannula comprising a cannula tube, wherein the cannula tube has a bend with a radially inward and a radially outward side of the cannula tube and a tube lumen and a tube wall and an axis extending parallel to the tube wall in the tube lumen and a distal and a proximal end and on the radially outward side of the bend a first window region having one or more openings in the tube wall. To provide a tracheostomy cannula having a cannula tube, with which talking is made possible and the entry of air into the tissue is prevented even when the position of the tracheostomy cannula in the trachea or the anatomical conditions change, it is proposed in accordance with the invention that the cannula tube has in axially displaced relationship with the first window region at least one further window region having one or more openings in the tube wall.

Abstract: The invention concerns a collar with a tracheotomy cannula or tube, wherein the collar embraces a respiratory tube in sealing relationship. The collar comprises separate inner and outer films, the outer film being elastically stretchable. The collar of the device allows no or only small tight folds formed which do not affect sealing integrity between the collar and the trachea wall even at low pressures. The outer film is expandable to a diameter larger than the diameter of a trachea, and in particular is at least 1.5 times the outside diameter of the tube, and the inner film comprises a material of lower elastic stretching. The inner film is produced oversized and without an external restriction at an internal pressure of at most 20 hPa assumes a diameter which is larger than the diameter of a trachea.
