Description
Изобретение относитс к медицинской технике , а именно к устройствам, используемым при трансплантации сердца, в частности к устройствам дл нагрева крови при имплантации искусственного сердца.The invention relates to medical technology, namely to devices used in heart transplantation, in particular to devices for heating blood during implantation of an artificial heart.
Известно устройство дл нагрева крови при имплантации искусственного сердца, выполненное в виде металлической трубки, на внешней стороне которой последовательно размещены электронагревательный элемент и теплоизол ци 1.A device is known for heating blood during implantation of an artificial heart, made in the form of a metal tube, on the outer side of which a heating element and thermal insulation 1 are sequentially placed.
Однако это устройство обладает р дом недостатков, затрудн ющих получение длительной выживаемости животного с имплантированным искусственным сердцем. К этим недостаткам относ тс необходимость пережати кровеносного сосуда на срок до 30 мин при иплантации устройства в кровеносное русло или применение методов обходного шунтировани , что усложн ет процесс имплантации, и наличие чужеродного материала, контактирующего с кровью и вл ющегос источником тромбообразовани .However, this device has a number of disadvantages that make it difficult to obtain a long-term survival of an animal with an implanted artificial heart. These disadvantages include the need to hold the blood vessel for up to 30 minutes when the device is implanted into the bloodstream or the use of bypass shunting methods, which complicates the implantation process, and the presence of foreign material in contact with blood and a source of blood clots.
Целью изобретени вл етс исключение тромбообразовани путем устраЕ1ени контакта устройства с кровью.The aim of the invention is to eliminate thrombosis by eliminating contact of the device with blood.
Поставленна цель достигаетс тем, что устройство выполнено в виде манжеты, одеваемой на сосуд.The goal is achieved by the fact that the device is made in the form of a cuff, worn on the vessel.
На фиг. 1 изображено предлагаемое устройство , общий вид; на фиг. 2 - то же, поперечный разрез; на фиг. 3 - электронагревательный элемент.FIG. 1 shows the proposed device, a general view; in fig. 2 - the same, cross section; in fig. 3 - electric heating element.
Устройство дл нагрева крови содержитA device for heating blood contains
металлическую трубку 1, электроизол циюmetal tube 1, electrically insulated
2, электронагревательный элемент 3 и теплоизол цию 4. Все устройство выполнено2, electric heating element 3 and heat insulation 4. The whole device is made
в виде манжеты.in the form of a cuff.
Устройство работает следующим образом .The device works as follows.
После вскрыти грудной клетки устройство надеваетс на кровеносный сосуд и закрепл етс на нем одним из известных способов . Питание электронагревательного элемента 3 осуществл етс от специального регулируемого источника тока.After opening the chest, the device is put on the blood vessel and secured to it by one of the known methods. The power of the electric heating element 3 is supplied from a special regulated current source.
