摘要： 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.

摘要： 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.

摘要： 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.

摘要： A device for inserting a tracheal tube into a tracheostomy has as insertion aid with a shaft (6, 6′, 14) which can be inserted through the tracheal tube, and a conical tip (2, 13) which is or can be joined to the tracheal tube. In order to provide a device for inserting a tracheal tube which considerably reduces the risk of injury when inserting the tracheal tube, which makes the insertion process easier, the inserted tube being highly comfortable even with a long-term use, keeping low the danger of injuries or sore points in the trachea, the insertion aid according to the invention has a conical tip (2, 13) which can have a small base diameter in a first state and a large base diameter in a second state. The insertion aid includes a section (6′, 14) adjacent to the conical tip (2) whose diameter corresponds at the most to the inner diameter of a tracheal tube (1) to be inserted by means of the insertion aid, the small base diameter of the conical tip also being at the most equal to the inner diameter of the tracheal tube, while the large base diameter of the conical tip is larger than the inner diameter of the tracheal tube and preferably corresponds to approximately the outer diameter of the tracheal tube to be inserted with the insertion aid.
