Problems solved by technology
[0013] However, it has been shown that the delivery line cross-section alone does not guarantee the fastest possible pressure equalization in the intracorporeal balloon, but rather the overall structural design of the flow path between the intracorporeal balloon and the extracorporeal regulating device has an impact on the achievable flow rate. have an effect on the temporarily movable filling pressure volume

Embodiment Construction
[0076] figure 1The catheter according to the invention is exemplarily described in connection with a tracheal catheter 1, which consists of a rod element 2 which carries a tracheal sealing cuff 3 at the distal end, wherein the cuff is passed through a channel-shaped integrated in the rod part. The delivery line 4a is connected to an extracorporeal volume reservoir 5a, which transitions outside the stem to a filling hose 4b, which loads the cuff with filling pressure or stores a gas filling medium with a tracheal seal nominal pressure, or the The cuff is connected to an electronically regulated volume source 5b which regulates the tracheal seal nominal pressure by the pressure differential produced by the volume source or which exceeds the tracheal seal nominal pressure. The reservoir or the source is connected to the filling hose 4b by means of the connector 6 . In addition to the branch 7 , which is closed by means of the connector 6 , the filling hose 4 b has a further bran...

The invention relates to a device for dynamically adapted sealing of organs or body cavities, for example the trachea of a patient having been intubated and using a respirator, in which a sealing balloon element is created by a particularly rapid movement of a filling medium from an extracorporeal reservoir or an extracorporeal source to the sealing balloon, in an exemplary case of dynamic sealing of the trachea, a balloon-like film body, which is preferably residual-shaped in a diameter that exceeds the diameter of the trachea, abuts against the inner wall of the trachea in a sealing manner at a pressure that is as constant as possible. Wherein fluctuations in the volume of the balloon caused by fluctuations in the intrathoracic pressure associated with respiratory mechanics are compensated for with a time delay as short as possible by delivering the volume from an extracorporeal reservoir or an extracorporeal source and the tracheal secretions of the balloon are always kept sealed. According to the invention, the above-mentioned solution is achieved on the one hand by means of a delivery line which leads to the lumen of the balloon filling medium of the cuff and on the other hand by avoiding steps, gaps or burrs in the delivery line in order to achieve a minimization of the volumetric flow towards the balloon, which is crucial for the as fast as possible stabilization of the filling volume in the balloon, in particular at a small pressure difference of the driving volume flow of about 15 to 30 mbar.
Description
technical field [0001] The present invention relates to a device for organ-synchronized and dynamic occlusion, sealing and / or packing of hollow organs by means of balloon-like elements, in particular for spontaneously breathing patients and patients mechanically ventilated in an assisted spontaneous breathing mode, Dynamically adapted, aspiration-resistant secretion seal for intubated trachea. In particular, the present invention relates to a device for dynamically adaptive sealing of organs or body cavities, in particular by means of sealing balloon elements, for example sealing the trachea of an intubated and ventilated patient, wherein in the example of dynamic sealing of the trachea In this case, the balloon-like film body preferably remaining formed in the diameter, that is to say exceeding the diameter of the trachea, rests tightly against the inner wall of the trachea with as constant a pressure as possible; in this case, it should pass through with the shortest possi...
