Abstract
Description
"Blutdruckmessgerät mit Solarzellen" Bekanntes: Es sind vielerlei elektronisch betriebuer Plltdruckmessgeräte bekannt geworden, deren Betriebsstrom sowbhl Batterien entnommen wird, als auch über Trer:rtransformatoren und gleichwie ausgeführte Netzanschlussteile aus dem Lichtnetz entnommen wird, Im Falle der Batteriespeisung treten die bekannten Schwierigkeiten aller batteriebetriebenen Geräte auf, wie beispielsweise Auslaufen iilJeralterter Batterien, Beschaffungsschwierigkeiten für Ersatzbaterien."Blood pressure monitor with solar cells" Known: There are many things electronically Betriebsuer Plltdruckmessgeräte become known, their operating current both batteries are removed, as well as via Trer: rtransformatoren and alike executed mains connection parts are taken from the lighting network, in the case of battery supply the well-known difficulties of all battery-operated devices arise, such as Obsolete batteries are being phased out, difficulties in obtaining replacement batteries.
Im Falle der Netzspeisung sind die Sicherheitsbedingungen und die Brummschleifenbedingungen erschwerend. Geräte mit aus fremden Stromçuellen aufladbaren Akkumulatoren beinhalten eine Mischung aus vorgenannten Schwierigkeiten besonders dann, wenn die für die Elektronik des Bludruckmessers erforderliche Betriebsspannung im üblichen Bereich um etwa 9 Volt liegt.In the case of mains supply, the safety conditions and the Aggravating hum loop conditions. Devices with rechargeable electricity from other sources Accumulators in particular involve a mixture of the aforementioned difficulties when the operating voltage required for the electronics of the blood pressure meter is in the usual range around 9 volts.
Effindungsgedanke: Die Elektronik des Blutdruckmessers wird so ausgelegt, dass als Betriebsspannung etwa 1 Volt, instesondere die Klemmenspannung einer Nickelcaitmium-Zelle al so etwa 1,2 Volt, ausreicht. Diese Speicherzelle wird über eire Diode aus einer entsprechenden Anzahl in Reihe geschalteter sogenannter Solarzellen aufgeladen. Bei heutigen Solarzelien werden dazu etwa 6 Solarzellen in Reihe geschaltet, um auch bei mässiger Beleuchtung die Speicherzelle aufladen zu können.Idea of development: The electronics of the blood pressure monitor are designed in such a way that that the operating voltage is about 1 volt, in particular the terminal voltage of a nickel calcium cell al so about 1.2 volts is sufficient. This memory cell is made from a corresponding number of so-called solar cells connected in series. In today's solar cells, around 6 solar cells are connected in series to achieve this to be able to charge the storage cell even with moderate lighting.
Wird eine Reihenschaltung aus 7 Solarzellen benutzt, so ist eine sichere Aufladung bereits mit Glühlampenlicht mittlerer Helligkeit erreichbar.If a series connection of 7 solar cells is used, it is safe Charging can already be achieved with incandescent light of medium brightness.
Soll die Speicherzelle des Blutdruckmessgeräts unter Benutzung vorhandener Stromquellen wie beispielsweise Irichtnetz, Bordnetz in Fahrzeugen und anderweitigen Stromquellen aufgeladen werden, so bedarf es nicht der Benutzung spezieller Netzanschlussteile der herkömmlichen Form, sondern die zur Aufladurg zu benutzende vorhandene Stromquelle speist eine einfache Glühlampe, deren Licht möglichst wirkungsvoll gebündelt die Solarzellen des Blutdruckmessgeräts trifft. Einfache Anordnungen, die beispielsweise an die Bordsteckdose eines Autos oder an die Steckdose im Wohnraum angeschlossen werden können, und an deren Lichtaustritt die Solarzellen angenähert und nìittels an sich bekannter Halte Auflege, Einschiebt und/oder Haftmittel angebracht werden, sind erfindungsgemäss virgesehen. Es wird besonders darauf hingewiesen, dass derartige Aufladegerate die o.g. Schwierigkeiten eines Netzbetriebs" nicht erheben.Should the memory cell of the blood pressure monitor using an existing one Power sources such as electrical systems, vehicle electrical systems and others Power sources are charged, so it does not require the use of special mains connection parts the conventional form, but the existing power source to be used for charging feeds a simple incandescent lamp whose light is bundled as effectively as possible The solar cells of the blood pressure monitor. Simple arrangements such as connected to the on-board socket of a car or to the socket in the living room can be, and at the light exit of which the solar cells are approached and not by means of known holding means are applied, inserted and / or adhesives are applied, are seen according to the invention. It is particularly pointed out that such Charging devices do not raise the above-mentioned difficulties of network operation ".
Es erfolgt in keinem Falle eine elektrisch leitende Verbindung zwischen Blatt 2 "Blutdruckmessgerät mit Solarzellen" dem zur Aufladung der Speicherzelle benutzten Netz und dem Blutdruckmesser.In no case is there an electrically conductive connection between sheet 2 "Blood pressure monitor with solar cells" the one used to charge the storage cell Network and the sphygmomanometer.
Erfindungsgemäss ist weiterhin vorgesehen, die Aufladung der Speicherzelle des Blutdruckmessers durch Anwendung von Licht geeigneter Wellenlänge und beliebiger anderer quelle vorzunehmen und/oder entsprechende Vorrichtungen hierzu darzustellen. eispielsweise kann das Licht einer einfachen Petroleumlampe mit oder ohne Benutzung von Bündelungsmitteln wie etwa Sammellinsen und/oder Hohlspiegel berutzt werden.According to the invention it is also provided that the storage cell is charged of the sphygmomanometer by using light of suitable wavelength and any make another source and / or represent corresponding devices for this purpose. For example, the light of a simple kerosene lamp can be used with or without use be used by focusing means such as converging lenses and / or concave mirrors.
Gaslampen oder offene Flammen sind gleichfalls benutzbar.Gas lamps or open flames can also be used.
Erflndungsgemass kann, um Störungseinflüsse durch nicht konstante Beleuchtung der Solarzellen auszuschliessen, die Verbindung zwischen den Solarzellen und der Elektronik des Blutdruckmessers während der Durchführung einer Messung unterbrochen werden. Hierzu können spwohl mechanische Kontakte als auch gesteuerte Halbleiter angewandt werden.According to the invention, in order to avoid interference effects from non-constant Illumination of the solar cells exclude the connection between the solar cells and the electronics of the sphygmomanometer are interrupted while a measurement is being carried out will. Mechanical contacts as well as controlled semiconductors can be used for this purpose can be applied.
Es ist erfindungsgemäss weiterhin vorgesehen, das vorbezeichnete Verfahren auch auf andere medizinische Messgeräte anzuwenden.According to the invention, the aforementioned method is also provided also apply to other medical measuring devices.
Es ist erfindungsgemäss weiterhin vorgesehen, die störende Wirkung nicht konstanter Beleuchtung auf den Solarzellen während der Durchführung einer Messung dadurch auszuschliessen, dass die Solarzellen während der Messung weitgehend lichtdicht abgedeckt werden, beispielsweise durch eine mechanische Flende, welche mit dem Einschalter für die Messung mechanisch gekoppelt sein kann.According to the invention, the disruptive effect is also provided inconsistent lighting on the solar panels while performing a Exclude measurement by keeping the solar cells largely during the measurement be covered light-tight, for example by a mechanical Flende, which can be mechanically coupled to the on-switch for the measurement.
