neurogenen Harnblaseneurogenic urinary bladder
Die Erfindung betrifft eine Vorrichtung zur künstlichen Entleerung des Inhalts der neurogenen Harnblase^ durch deren aus einer Entfernung erfolgenden elektrischen Neurostimulation, was insbesondere nach einem Traumatismus des Rückenmarks sowie bei anderen Beschwerden des Nervensystems vorteilhaft sein kann.The invention relates to a device for the artificial emptying of the contents of the neurogenic urinary bladder ^ through the latter remote electrical neurostimulation what especially after a trauma to the spinal cord as well as other ailments of the nervous system.
Es gibt verschiedene Verfahren, um die Zurückhaltung des Harns zu behandeln, die als Folge von Traumatismen des Marks oder anderen Beschwerden des Nervensystems auftritt:There are several different procedures to treat urine retention that occurs as a result of trauma to the urine Marks or other nervous system ailments occurs:
Die intermittierende Dränage durch urethrale^Eath&terbehandlung besitzt einerseits den Nachteil der Gefahr einer urinären Infektion mit deren Komplikationen (Steinbildung, Pyelonephritis, TJrämie), andererseits ist es unmöglich, diese Behandlungsweise in allen Fällen anzuwenden (urethraleThe Intermittent Drainage by Urethral Eatheter Treatment on the one hand has the disadvantage of the risk of urinary infection with its complications (stone formation, Pyelonephritis, trauma), on the other hand it is impossible to use this mode of treatment in all cases (urethral

Strikturen, Risse der Harnröhre etc.). Die dauernde Dränage mit einer urethralen Sonde birgt eine erheblich grössere Infektionsgefahr in sich, genau so wie Veränderungen des Muskelgewebes und der Elastizität der Harnblase, Urämie etc.Strictures, tears of the urethra etc.). The constant drainage with A urethral probe carries a significantly greater risk of infection, as does changes in muscle tissue and the elasticity of the urinary bladder, uremia etc.
Die Cystostomie, die fast nicht mehr angewandt wird, verzögert abgesehen von der Gefahr einer Infektion, die Wiedererlangung der Kontraktionsreflexe der Harnblase und stellt eine erhebliche Belästigung für den Patienten dar.The cystostomy, which is almost no longer used, delays recovery, apart from the risk of infection the contraction reflexes of the urinary bladder and represents a considerable annoyance for the patient.
Ausserdem gibt es ein Verfahren, bei dem eine direkte elektrische Stimulation des Harnblasenmuskels erfolgt. Diese Stimulation wird mit Hilfe von Elektroden aus Stahldrähten oder in Form von Scheiben, welche auf der Harnblasenwand befestigt sind, hervorgerufen. Die Elektroden sind mit einem Empfänger verbunden, der auf chirurgischem Wege unter die Haut eingeführt worden ist. Dieser wird mittels eines äusseren Senders von herabgesetzter Eindringleistung in Tätigkeit gesetzt.There is also a method in which direct electrical stimulation of the urinary bladder muscle takes place. This stimulation is carried out with the help of electrodes made of steel wires or in the form of discs, which are attached to the urinary bladder wall, evoked. The electrodes are connected to a receiver that has been surgically inserted under the skin is. This is activated by means of an external transmitter of reduced penetration power.
Auf Grund einer hochinduzierten elektromotorischen Spannung von bis zu 40 Volt besitzt d.ieses Verfahren den Nachteil, dass gleichzeitig während der Stimulation Schmerzen erzeugt werden sowie Kontraktionen der Muskulatur der unteren Glieder und des Unterleibes, weiterhin Brandwunden und Narben auf dem Niveau der Stimulation, Performationen des Blasenwand und Unterbrechungen des Leiters durch die Bewegungen. Das sind Nachteile, welche der Anwendungsmöglichkeit eines derartigen VerfahrensDue to a highly induced electromotive voltage of up to 40 volts, this method has the disadvantage that At the same time, pain and contractions of the muscles of the lower limbs and the lower limbs are produced during the stimulation Abdomen, burns and scars continue at the level of stimulation, perforations of the bladder wall and interruptions of the leader through the movements. These are disadvantages of the possibility of using such a method
