Claims (42)

1. Устройство для создания разрежения в области раны, предназначенное для создания в области раны локального разрежения, содержащее
источник разрежения;
процессорный элемент; и
запоминающее устройство, содержащее инструкции, составленные таким образом, что их выполнение процессором обеспечивает осуществление указанным устройством следующих операций:
осуществление попыток создания в области раны требуемого разрежения при помощи источника разрежения;
отключение источника разрежения на второй заданный период времени, если по истечении первого заданного периода времени требуемое разрежение не создано;
осуществление последующих попыток создания в области раны требуемого разрежения,
при этом источник разрежения является насосом, который приводится в действие электродвигателем, который питается от аккумуляторной батареи.
2. Устройство по п. 1, в котором указанные инструкции составлены также таким образом, что обеспечивают осуществление указанным устройством следующих операций:
отключение источника разрежения на второй заданный период времени, если по истечении дополнительного заданного периода времени требуемое разрежение не создано.

последующее осуществление попыток создания в области раны требуемого разрежения.
17. Устройство по любому из пп. 1-5, 7, 8, 10, 11, 13-15, в котором указанные инструкции составлены также таким образом, что обеспечивают осуществление указанным устройством следующих операций:
контроль рабочего цикла источника разрежения; и
отключение источника разрежения, если рабочий цикл превышает порог рабочего цикла без создания требуемого разрежения в области раны.
18. Устройство по п. 17, в котором рабочий цикл содержит количество времени, в течение которого источник разрежения включен сверх лимита времени.
19. Устройство по п. 18, в котором указанные инструкции составлены также таким образом, что обеспечивают осуществление указанным устройством следующих операций:
отключение источника разрежения, если рабочий цикл превышает порог рабочего цикла сверх некоторого промежутка времени.
