Abstract
Description
[Stand der Technik][State of the art]
Die Erfindung betrifft eine Haftvorrichtung für Prüfköpfe zum Einsatz in der medizinischen Diagnostik. Diese kann bei der Aufnahme von Messsignalen am Patientenkörper eingesetzt werden.The invention relates to an adhesive device for test heads for Use in medical diagnostics. This can be done when recording of measurement signals on the patient's body be used.
Dabei kommt es häufig vor, dass sich auf Grund von Bewegungen zwischen Prüfkopf und Haut des Patienten die Haftvorrichtung (z.B. eine Saugelektrode) lockert, was zur Verfälschung der Messergebnissen führt. Lockere Haftvorrichtungen können ferner unerwünschte Bewegungsartefakte hervorrufen. Außerdem sollte die Haftvorrichtung selbst keine störenden Signale emittieren.It often happens that due to of movements between probe and skin of the patient the adhesive device (e.g. a suction electrode) loosens what distorts of the measurement results. Loose adhesive devices can also be used undesirable Cause movement artifacts. In addition, the adhesive device itself no annoying Emit signals.
Eine Haftvorrichtung nach dem Stand
der Technik ist aus der Patentschrift
In der Auslegeschrift 2365008 wird eine Vorrichtung zum Betrieb von Saugelektroden beschrieben, mit wenigstens einer Saugelektrode, die über eine pneumatische Leitung mit einer Saugpumpe verbunden ist, wobei ein Strömungsfühler in der pneumatischen Verbindung zwischen Saugelektrode und Saugpumpe eingeordnet ist.In the design specification 2365008 a device for operating suction electrodes described, with at least one suction electrode via a pneumatic line is connected to a suction pump, with a flow sensor in the pneumatic connection is arranged between the suction electrode and the suction pump.
Des weiteren gibt es eine Ankopplungs-
und Haftvorrichtung für
Schallsender, die durch die
Alle vorgenannten Schriften haben weisen den Nachteil auf, dass sich der Prüfkopf schnell lockert, oder dass -aufgrund zu hohem Unterdruck- die Hämatombildung im angesaugten Hautbereich gefördert wird.Have all of the above have the disadvantage that the test head loosens quickly, or that - due to high negative pressure - the hematoma formation in the aspirated Skin area promoted becomes.
[Aufgabe der Erfindung]OBJECT OF THE INVENTION
Aufgabe der Erfindung ist es daher, eine Haftvorrichtung zu schaffen, die den praktischen Einsatz von Prüfköpfen für die medizinische Diagnostik auf der Grundlage einer Unterdruckhaftung vereinfacht oder verbessert.The object of the invention is therefore to create an adhesive device that the practical use of Probes for medical Diagnostics based on negative pressure liability simplified or improved.
Die gestellte Aufgabe wird erfindungsgemäß durch eine Haftvorrichtung für Prüfköpfe nach Anspruch 1 gelöst, die alle oben genannten Bedingungen für vernünftige Messergebnisse mittels eines Prüfkopfes am Patientenkörper erfüllt.The object is achieved according to the invention an adhesive device for Probes after Claim 1 solved, using all of the above conditions for reasonable measurement results a test head on the patient's body Fulfills.
Zwischen den beiden Kammern besteht
eine pneumatische Verbindung (
Die Kompensationskammer ist ebenfalls
vorzugsweise als axial beweglicher Faltenbalg ausgeführt und
verfügt über ein
handbetätigtes
federbelastetes Ventil (
Beim Andrücken der Vorrichtung über die Betätigungsscheibe
(
Die entwickelte Haftvorrichtung weist folgende Vorteile auf:
- – Der Prüfkopf lässt sich durch einfaches Andrücken der Vorrichtung sicher, positionsgenau und reproduzierbar ankoppeln
- – Die Anpresskraft des Prüfkopfes lässt sich über die Wahl der Kompensationsfeder oder mittels Einbau einer Feder mit einer verstellbaren Federkonstante variieren
- – Durch die leichte Bauweise wird nur ein kleiner Unterdruck für eine sichere Ankoppelung benötigt
- – Es ist kein externer apparativer Aufwand zur Unterdruckerzeugung nötig
- – Die Vorrichtung lässt sich nach der Messung durch die Belüftung derselben über das Ent-/Belüftungsventil leicht und ohne Hautirritationen beim Patienten abnehmen
- – Durch die Verwendung der Werkstoffe Silicon, Stahl und Aluminium sowie die einfache Demontage der Vorrichtung lässt sich diese unproblematisch desinfizieren
- - The test head can be easily pressed Connect the device securely, precisely and reproducibly
- - The contact force of the test head can be varied by choosing the compensation spring or by installing a spring with an adjustable spring constant
- - Due to the lightweight design, only a small negative pressure is required for a safe connection
- - There is no need for external equipment to generate negative pressure
- - After the measurement, the device can be removed easily and without skin irritation from the patient by ventilation of the device via the ventilation valve
- - The use of silicone, steel and aluminum as well as the simple disassembly of the device make it easy to disinfect
Die Handhabung der Haftvorrichtung ist ebenfalls einfach und praktisch. Vor dem Ankoppeln der Vorrichtung an eine Hautoberfläche wird diese mit einem Koppelmittel, in Form einer hautverträglichen, niederviskosen Fettpaste, eingerieben.Handling the adhesive device is also simple and practical. Before coupling the device to a skin surface is this with a coupling agent, in the form of a skin-friendly, low-viscosity fat paste, rubbed in.
Das eigentliche Ankoppeln wird durch
einfaches Andrücken
der Vorrichtung mittels der Betätigungsscheibe
an die Hautoberfläche
realisiert. Dabei entlüften
sich die beiden Kammern über
das Be- und Entlüftungsventil.
Nach dem Wegnehmen des Andruckes schließt sich das Be-/Entlüftungsventil
(
Die, durch den auf die Kompensationsfläche (
Die Verbindung zwischen der Haftvorrichtung und der Körperoberfläche wird durch das leichte Andrücken des Prüfkopfes gegen die Haut sichergestellt. Während der Messung kann die Ansaugkammer den bei der Bewegung auftretenden Oberflächenveränderungen folgen. Treten doch kleinere Leckagen auf, so dehnt sich die Kompensationskammer so lange aus, bis das Rückstell-/Federkraft-Gleichgewicht und somit die Ansaugkraft wieder hergestellt ist.The connection between the adhesive device and the body surface will by pressing lightly of the test head ensured against the skin. While During the measurement, the suction chamber can detect those that occur during the movement surface changes consequences. If small leaks do occur, the compensation chamber expands until the return / spring force balance and thus the suction force is restored.
