Description
Vynález se. týká držáku tenzometrické membrány čidla měřiče krevního tlaku pro lékařské účely.The invention is. relates to a strain gauge membrane holder for a blood pressure meter sensor for medical purposes.
Známá provedení držáku tenzometrických membrán jsou zhotovována například ze slitiny 54 Z železa, 28 % niklu a 18 Z kobaltu, skla a nerezavějící oceli. Všechny uvedené materiály se vyznačují obtížnou obrobitelností. Při použití slitiny 54 % železa, 28 Z niklu a 18 % kobaltu není dosahováno dokonalé korosní odolnosti, sklo se naopak vyznačuje vysokou křehkostí. Držáky z nerezavějící oceli se vyznačují vysokou tepelnou roztažností, která snižuje technické parametry tenzometrických membrán.Known embodiments of the strain gauge diaphragm holder are made, for example, of an alloy 54 of iron, 28% nickel, and 18 of cobalt, glass and stainless steel. All of these materials are difficult to machine. When using an alloy of 54% iron, 28 nickel and 18% cobalt, perfect corrosion resistance is not achieved, while glass is characterized by high brittleness. Stainless steel holders are characterized by high thermal expansion which reduces the technical parameters of strain gauge membranes.
Předmětem vynálezu je držák tenzometrické membrány čidla měřiče krevního tlaku zhotovený z titanu,popřípadě z jeho slitin, například slitiny 92,5 X titanu, 5 Z hliníku, 2,5 X cínu, nebo slitiny 92 % titanu,The subject of the invention is a tensometric diaphragm holder of a blood pressure sensor made of titanium or its alloys, for example an alloy of 92.5 X titanium, 5 of aluminum, 2.5 X tin or an alloy of 92% titanium,
Z hliníku, 3 Z cínu.Made of aluminum, 3 made of tin.
Povrch držáku zhotovený z uvedených materiálů ja pasivován vrstvou kysličníku titanu. Držák zhotovený podle vynálezu seThe surface of the holder made of said materials is passivated by a titanium oxide layer. The holder made according to the invention is
