摘要： The present invention concerns a fistula insert with a tubular body which has a distal and a proximal end and a central lumen, in particular to seal fistulas in connection with voice prostheses, speech valves, tracheal cannulas, stoma buttons and connectors. To produce such a device, which on insertion can be conformed individually to the size and shape of the stoma or fistula and produce a suitable seal, in accordance with the invention, the tubular body has an outer surface which can be conformed to the shape of a fistula to be sealed and an inner surface which is essentially stable in shape.

摘要： 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.

摘要： 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. In order therefore to keep the cuff pressure within the pressure range that is generally considered to be useful and optimal of between approximately 20 mbar and 30 mbar, but also make possible, if required, to increase the pressure in a controlled manner, according to the invention the equalizing balloon keeping the pressure generally constant is accommodated in a protective sleeve which has radial bulges deviating from a uniformly concave form matched to the outer contour of the balloon, which bulges are designed such that the equalizing balloon first abuts against the wall areas of the protective sleeve matched to the contour of the balloon and then, when pressure is increased, extends only into the bulges, whereby the pressure in the equalizing balloon gradually increases as the volume in the bulges increases.

摘要： 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.

摘要： The present invention concerns a device having a guide catheter for the introduction of a tracheal cannula into a tracheostoma. To provide a device for introducing a tracheal cannula into a tracheostoma, which prevents injury by the distal end face of the cannula and which is suitable for use in relation to highly flexible cannulas, in relation to cannulas of tight inside diameter and/or of large wall thickness, it is proposed in accordance with the invention that the guide catheter has a shield which is mounted in the proximity of the distal end of the guide catheter and which comprises a flexible material and which is substantially in the form of a distally directed conical tip, wherein the tube of the guide catheter passes through the axis of said tip, with a base outside diameter which in a first state corresponds at least to the outside diameter of the tracheal cannula and in a second state by deformation is smaller than the inside diameter of the tracheal cannula and is thus retractable through the tracheal cannula.
