Medizintechnische Wärmvorrichtung für Hand und Arm zur Vorbehandlung der Venen im Armbereich stark geschwächter Patienten oder Patienten, deren Venen lagebedingt oder krankheitsbedingt von einer den Patienten behandelnden Person schwer auffindbar sind.Medical device for hand and arm pretreatment Veins in the arm area of severely weakened patients or patients whose veins due to location or illness due to a person treating the patient are difficult to find.

Medizintechnische Wärmvorrichtungen sind in unterschiedlicher Form bekannt, wie z. B. Heizkissen, Infrarotstrahler, Wärmflaschen oder dergleichen. Es ist allerdings nicht bekannt, eine medizintechnische Wärmvorrichtung für eine Vorbehandlung der Venen in bestimmten Fällen einzusetzen, in denen dies für die Behandlung eines Patienten erforderlich ist. Bei sehr stark geschwächten Patienten oder bei Patienten mit langen Liegezeiten oder aber bei Patienten während einer Chemotherapie und auch bei Patienten mit chronischer Polyarthritis ist es für den behandelnden Arzt oder den geschulten Mitarbeiter häufig sehr schwer, für Injektionen und Punktionen immer wieder die Venen im Arm, insbesondere im Unterarm, zu finden. Zum Teil benötigen selbst erfahrene Ärzte bis zu zwölf Versuche, bis sie in solchen Fällen die Vene gefunden haben. Dies ist für die betreffenden Patienten sehr schmerzhaft und führt zu Vertrauensverlusten gegenüber dem Arzt oder der behandelnden Person und zu einem erheblichen Zeitverlust für den Arzt bei der Behandlung seiner Patien­ ten.Medical heaters are known in various forms, such as e.g. B. heating pads, infrared heaters, hot water bottles or the like. However, it is not known, a medical device for pretreatment use of the veins in certain cases where this is necessary for the treatment of a Patient is required. In very weakened patients or in patients with long lay times or with patients during chemotherapy and it is also for the treating doctor in patients with chronic polyarthritis or the trained employee is often very difficult for injections and punctures to always find the veins in the arm, especially in the forearm. Partly Even experienced doctors need up to twelve attempts before they can do this Have found a vein. This is very painful and painful for the patient concerned leads to a loss of trust in the doctor or the treating person and a considerable loss of time for the doctor in treating his patients ten.

Die bekannten medizintechnischen Wärmvorrichtungen sind unpraktisch und nicht geeignet, gezielt dafür eingesetzt zu werden, Venen im Armbereich eines Patienten für den behandelnden Arzt oder seinem Mitarbeiter besser auffindbar zu machen.The known medical heating devices are impractical and not suitable to be used specifically for veins in the arm area of a patient make it easier for the attending doctor or his staff to find.

Die Aufgabe der vorliegenden Erfindung ist daher, eine medizintechnische Wärm­ vorrichtung der eingangs genannten Art zu schaffen, mit der die Auffindbarkeit der Venen bei Patienten mit entsprechender Problematik nach der Vorbehandlung er­ heblich zu verbessern. The object of the present invention is therefore a medical heat to create device of the type mentioned, with which the findability of the Veins in patients with corresponding problems after the pretreatment to improve significantly.  

Die Aufgabe wird erfindungsgemäß durch eine medizintechnische Wärmvorrichtung gelöst, die gekennzeichnet ist durch eine Hülle mit einer Öffnung zur Aufnahme von Hand und Arm aus einem wärmeisolierenden Material und mit einer Wärmeeinrich­ tung, die in die Hülle integriert ist und über einen Anschluß mit einer Steuereinrich­ tung zur Wärmesteuerung verbunden ist.The object is achieved by a medical heating device solved, which is characterized by a shell with an opening for receiving Hand and arm made of a heat-insulating material and with a heating device device, which is integrated in the case and via a connection with a control device device for heat control is connected.
