У меня тут три дня скачет давление, и я пользуюсь новым электронным тонометром. Это прибор размером чуть больше пачки сигарет, крепится на запястье и питается от пары ААА батареек. Он полностью автоматический: надел, нажал одну кнопку, всё.
Моё поколение застало, как измеряли давление наши родители: манжета на плечо, которую не всегда легко затянуть одной рукой. Необходимость вручную накачать её грушей, а усилие для этого требуется немаленькое — удивительно, как бабушки справлялись. Затем нужно правильно закрепить головку стетоскопа на сгибе локтя. И слушать, параллельно следя за аналоговой стрелкой и стравливая воздух в нужном темпе.
Технологии в этом отношении сделали гигантский шаг в плане удобства. Хотя ничего принципиально магического в современном тонометре нет: и электрический компрессор и возможность прибором определить сердцебиение были и раньше. Но развитие вот таких бытовых вещей в целом идёт по пути автоматизации и уменьшения размеров. Можно попредставлять, какая техника сейчас не слишком удобна, и куда её будут улучшать. Хотя, конечно, где-нибудь в пределе ТРИЗ намекает нам о том, что решать задачу нужно совсем иначе — например, собрать человеку новое тело, вообще не нуждающееся в измерении давления. Но это уже другая история.
