Abstract

Thorax pump allows extraction of blood, tissue secretions and air from the thorax cavity via the mediastinum, with continuous adjustment in a range between 0 and 60 mbar. A battery provides the electrical operating energy and a control computer provides electronic pump regulation. The thorax pump uses a vacuum pump powered by a battery which allows continuous operation for a duration of up to 10 hours, with a red diode providing an optical warning signal when the battery charge drops below 30 %. The pump has an overall weight of 2.3 kg and is attached to a belt.

Description

Ich stelle den Antrag auf Erteilung des Patentes an einer Thoraxsaugpumpe, die in ihrer Wirkweise elektronisch geregelt ist und nach der Bauart dem Patienten eine fast vollständige Bewegungsfreiheit, unabhängig vom Stromnetz oder einer anderen stationären Einheit zur Sicherung eines konstanten Unterdrucks bei undichtem Lungenparenchym bietet.I am applying for a patent on a thoracic suction pump that is in their Mode of action is electronically controlled and according to the type of construction the patient almost complete freedom of movement, regardless of the power grid or any other stationary Unit for ensuring a constant negative pressure in the case of leaky lung parenchyma offers.

Die Unterdruckpumpe wird im weiteren als das Gerät bezeichnet.The vacuum pump is referred to below as the device.

Das Gerät dient der Dauersogtherapie bei Patienten nach Thorakotomie, Sternotomie, Erkrankungen (Pneumothorax) und Verletzungen mit Parenchymschädigung der Lunge.The device is used for continuous suction therapy in patients after thoracotomy, sternotomy, Diseases (pneumothorax) and injuries with parenchymal damage to the lungs.

Mit dem Gerät sollen über in die entsprechenden Körperhöhlen einzubringende Drainage­ schläuche Wundsekrete, Blut, Luft aus Leckagen des Lungenparenchyms mit konstantem, elektronisch gesteuertem Unterdruck abgesaugt werden.The device is said to have drainage to be inserted into the corresponding body cavities tubing wound secretions, blood, air from leaks in the lung parenchyma with constant, electronically controlled vacuum can be extracted.

Mit dem Gerät muß der Patient nicht mehr wie bisher an stationäre Systeme gebunden werden.With the device, the patient no longer has to be bound to stationary systems as before become.

Die in Anwendung befindlichen Absaugsysteme, die dem Patienten derzeit eine Bewegungsfreiheit gewähren, sind mit einem Gewicht von bis zu 7 kg zu schwer für kranke Menschen und bieten mit einer Batteriebetriebsdauer von unter einer Stunde eine zu kurze Dauer der Bewegungsfreiheit.The suction systems in use, which currently give the patient a Allowing freedom of movement is too heavy with a weight of up to 7 kg for sick people and offer with a battery life of less than one hour too short a period of freedom of movement.

Die bei dem Gerät erreichte besonders lange Betriebsdauer bei Batteriebetrieb erlaubt in ausgesuchten Fällen auch eine ambulante Behandlung entsprechend geeigneter Patienten und Krankheitsbilder. The particularly long operating time achieved with the device in battery operation allows in selected cases also outpatient treatment according to suitable patients and Clinical pictures.  

Der Unterdruck wird über eine mit Akku oder Netzteil betriebene Vakuumpumpe erzeugt.The negative pressure is generated by a vacuum pump operated with a battery or power pack.

Das Gerät ist stufenlos einstellbar in einem Bereich von 0 bis ≈ 60 mbar.The device is continuously adjustable in a range from 0 to ≈ 60 mbar.

Der Akku in Zusammenhang mit der Vakuumpumpe und der elektronischen Steuerung erlauben einen netzunabhängigen Betrieb des Gerätes unter Vollast von bis zu zehn Stunden bei einem Gewicht des Gerätes von knapp über zwei kg.The battery in connection with the vacuum pump and the electronic control allow mains-independent operation of the device under full load of up to ten Hours with a weight of the device of just over two kg.

Der Steuercomputer regelt die Abschaltung der Vakuumpumpe beim Erreichen eines maximalen Unterdrucks von 60 mbar.The control computer controls the shutdown of the vacuum pump when it reaches one maximum vacuum of 60 mbar.

Bei Erreichen einer Restkapazität des Akku von unter 30% wird ein optisches Signal (rote Diode) aktiviert.When the remaining battery capacity is below 30%, an optical signal (red Diode) activated.

Der Istwert des herrschenden Unterdrucks und der Ladekapazität wird laufend im Display angezeigt.The actual value of the prevailing negative pressure and the loading capacity is continuously shown on the display displayed.

Der Unterdruck wird über ein Drosselventil mit Lufteinlaßventil eingestellt.The negative pressure is set via a throttle valve with an air inlet valve.

Ein vorgewählter Sollwert kann nicht überschritten werden.A preselected setpoint cannot be exceeded.

Ein abnehmbarer, sterilisierbarer Sekretauffangbehälter mit Überlaufschutz dient zur Aufnahme der abgesaugten Sekrete.A removable, sterilizable secretion collection container with overflow protection is used for Absorption of the suctioned secretions.

Abgesaugte Luft aus Leckagen des Lungenparenchyms wird an die Umwelt abgegeben.Extracted air from leaks in the lung parenchyma is released into the environment.
