Abstract
Description
Bezüglich eines Zusatzpatentes für P 39 35 818.6 möchte ich nachträglich folgende Merkmale geltend machen: das Wundreinigungs-Therapiegerät Aquaderm benötigt zwei Pumpaggregate mit getrenntem Kreislauf. Zeichnung dazu wurde Ihnen bereits früher zugesandt. Die Bedienungsanleitung soll ebenfalls Inhalt des Zusatzpatentes sein. Insbesondere soll auch der Manschettenmechanismus geschützt werden, hier sind die Sprüh- und Düsenköpfe Inhalt des Gesamtsystems, diese können mehrdüsig, eindüsig und andere Merkmale aufweisen, auch die Druckgradienten können variieren, so Impulsdruckgradienten, Feineinstellung und massive Druckerhöhung bis zur Gewebsinfiltration. Auch die Absaugmechanismen sind in der Variabilität zu schützen, so können verschiedene Materialien dazu benutzt werden, auch doppelwandige Manschetten sind möglich. Auch die Absaugdüse ist mehreren Variationsmöglichkeiten ausgesetzt. Hier sind die verschiedenen Möglichkeiten unter Patentschutz zu stellen. Insbesondere ist die Gesamtheit des Gerätes, die aus vielen Einzelkomponenten besteht, den Patentregularien zu unterwerfen. Weiter wird ein Druckmanometer installiert werden, Barbereich etwa von 0-3 bar oder auch mehr. Auch ein Temperaturfühler zur Messung der Flüssigkeit ist möglich, ebenso soll eine Kurzzeituhr eingebaut werden, um die Länge der Applikation zu steuern. Auch diese Materialinhalte sind im gesamten Funktionsbild der Geräteeinheit dem Patentschutz zu unterstellen. Bisher sind keine Steuerungsmechanismen der Computerklasse vorgesehen, jedoch sind diese zu einem späteren Zeitpunkt notwendig, so wären auch diese, so sie der Gerätefunktion dienlich sind, zu patentieren. With regard to an additional patent for P 39 35 818.6, I would like to subsequently claim the following features: the wound cleaning therapy device Aquaderm requires two pump units with separate circuit. You have already been drawing sent earlier. The operating instructions should also contain the content of the Be additional patent. In particular, the cuff mechanism should also are protected, here the spray and nozzle heads are part of the Overall system, these can be multi-nozzle, one-nozzle and other characteristics the pressure gradients can also vary, so pulse pressure gradients, Fine adjustment and massive pressure increase up to Tissue infiltration. The suction mechanisms are also variable different materials can be used to double-walled cuffs are also possible. The suction nozzle is also exposed to several variations. Here are the different ones Possibility to put under patent protection. In particular is the entirety of the device, which consists of many individual components exists to submit to the patent regulations. Next one Pressure gauges can be installed, bar range from about 0-3 bar or also more. Also a temperature sensor for measuring the liquid is possible, a short-term clock should also be installed in order to control the length of the application. This material content too are patent protection in the entire functional picture of the device unit to assume. So far there are no control mechanisms Computer class provided, however, these are for a later If this was necessary, this would also be the case for the device function are useful to patent.
Die ringförmige, doppelwandige Absaug- und Reinigungsmanschette hätte den Vorteil, daß die Spannbänder wegfallen würden und die Manschette selbständig durch Unterdruck auf der Hautoberfläche haften würde, eine Zeichnung ist zur Demonstration beigegeben. Hierzu wäre in das Gerät noch eine zusätzliche Unterdruckpumpe einzubauen, die auf Luftbasis beruhen würde. Hier ergeben sich vielfältige Variationen, die ebenfalls patentrechtlich geschützt sein sollen.The ring-shaped, double-walled suction and cleaning collar would have the advantage that the straps would be eliminated and the cuff independently due to negative pressure on the skin surface would be liable, a drawing is attached to the demonstration. For this purpose there would be an additional vacuum pump in the device to incorporate that would be air-based. Here there are many variations, which are also patent law should be protected.
Was die zu entwickelnden Manschettenköpfe anlangt, so sind diese noch nicht parat, sollen jedoch alsbald produziert werden. Hier sind für die einzelnen Extremitäten verschiedene Paßformen zu entwickeln, wobei das generelle Prinzip der Spülung und Absaugung im Hautbereich beibehalten wird. Auch rektale und vaginale Drucksaugköpfe sind zu entwickeln und patentmäßig zu schützen. Durch durchsichtig gestaltete Manschettenköpfe und entsprechende Druckstrahlerhöhung kann auch eine Art Gewebeschneidung erfolgen, wobei hier jedoch noch stärkere Druckaggregate notwendig sind, die entwickelt werden sollen. Hier kann dann unter Aufsicht bzw. Durchsicht durch die Manschette, es ist auch ein glasfensterartiger Einsatz denkbar, eine lokale Entfernung nekrotischer Wundbestandteile (sogenannte Wundausschneidung) vorgenommen werden. Insgesamt wäre wichtig, daß das geschlossene Zirkulationssystem mit dem Aufsatz der Manschette und der Druck- bzw. Absaugdüse und auch die beschriebenen anderen Gerätschaften dem Patentschutz unterworfen werden. As for the cuff heads to be developed, these are not yet ready, but should be produced soon. Here are different fits for the individual extremities to develop, taking the general principle of flushing and Suction in the skin area is maintained. Rectal and vaginal too Pressure suction heads must be developed and patented protected. Through transparent cufflinks and corresponding A kind of tissue cutting can also be carried out however, even stronger printing units are necessary here, that are to be developed. Here, under supervision or Looking through the cuff, it's also a stained glass window Possible use, local removal of necrotic wound components (so-called wound cutting). Overall, it would be important that the closed circulation system with the attachment of the cuff and the pressure or suction nozzle and also the other devices described for patent protection be subjected.

Mittels der aufsetzbaren Manschette und der Reinigungsdüse kann bei ulcerösen Prozessen im Hautbereich, die meist mit pathogenen Keimen (Staphylokokken, Streptokokken) superinfiziert sind, eine problemlose Reinigung des Wundgrundes erfolgen. Im klinischen Bereich gilt die Wundreinigung bei Ulcus cruris (Dekubitalgeschwüre, Dekubitalsepsis u. a.) als eine Voraussetzung zum Wundheilungsprozeß.By means of the attachable sleeve and the cleaning nozzle in ulcerative processes in the skin area, mostly with pathogenic Germs (staphylococci, streptococci) superinfected are easy to clean the wound bed. In the clinical area, wound cleaning for leg ulcers applies (Decubitus ulcers, decubital sepsis, etc.) as a prerequisite to the wound healing process.
Bei der Applikation der Reinigungsmanschette sind zuvor die Wundgranulationen zu entfernen, dies geschieht am besten mittels einer Pinzette, danach kann die desinfizierende und reinigende Wasserlösung appliziert werden. Der Vorgang kann unbedenklich bis zum Abheilen des Geschwürs mehrmals wöchentlich erfolgen.When applying the cleaning cuff, the wound granulations are before to remove this is best done using a Tweezers, then the disinfectant and cleaning water solution be applied. The process can be safely until Heal the ulcer several times a week.
Der Wundrand ist mit einer wundpflegenden Salbe zu bestreichen, dann sterile Abdeckung.The wound edge is to be coated with a wound care ointment, then sterile cover.
Durch Ödeme, Varizen u. a. ist im Unterschenkelbereich stauungsbedingt eine schlechtere Sauerstoffversorgung vorhanden und der dadurch geschädigte Hautbereich vermehrt für infektiöse Prozesse und Ulcerationen anfällig. Deshalb ist in diesem Bereich eine peinliche Hygiene erforderlich, insbesondere sind Kratzeffekte und kleine Rhagaden zu vermeiden, der Spüllösung können auch Penizilline in löslicher Form u. a. Medikamente zugesetzt werden. Ein weiteres Indikationsgebiet zur Aquatherapie sind rheumatisch bedingte Schwellungen im Bereich großer Gelenke, hier kann allein durch gezielte Anwendung von wärmendem Wasser eine Umstimmung erfolgen, durch Zugabe von Kortikosteroiden, Salizylaten, Antirheumatika (in Form von Lösungen oder auch löslichen Tabletten) ist eine Potenzierung des Erfolges möglich.Through edema, varices and the like a. is due to congestion in the lower leg area poorer oxygen supply and the damaged skin area for infectious processes and susceptible to ulceration. Therefore there is one in this area embarrassing hygiene is necessary, especially scratching effects and to avoid small rhagades, the flushing solution can too Penicillins in soluble form u. a. Medicines are added. Another area of indication for aqua therapy is rheumatic conditioned swelling in the area of large joints, here alone a change of mind through the targeted use of warming water, by adding corticosteroids, salicylates, anti-inflammatory drugs (in the form of solutions or soluble tablets) a potentiation of the success is possible.
Gesicherte Erkenntnisse liegen jedoch hierzu noch nicht vor. Weiteres Indikationsgebiet sind degenerative Prozesse sowie punktförmige Knochenhautreizungen, wie Periostitis und Epicondy litis etc. Hier kann durch Druckstrahlerhöhung der Prozeß therapeutisch günstig beeinflußt werden. However, there is as yet no reliable knowledge. Another area of indication are degenerative processes as well punctate periostitis and epicondy litis etc. Here the process can be therapeutic by increasing the pressure jet be influenced favorably.
Die Kombination aus dem Aquaderm und einem Reizstromgerät, ähnlich wie bei einem Stangerbad, nur in Kleinformat, soll patentiert werden. Zu der bekannten Aquatherapie soll in geeigneter Form eine Elektrode in der Manschette angebracht werden, die auch bipolar, also in Mehrfachform, Reizströme in Wasser vermittelt. The combination of the Aquaderm and an electrical stimulation device, similar to a rod bath, only in small format, should be patented. The well-known aqua therapy is said in suitably form an electrode in the cuff, which are also bipolar, i.e. in multiple forms, stimulation currents in water mediated.
