Полезная модель относится к области медицины и медицинской технике, а именно к устройствам, предназначенным для вакуумного дренирования ран с использованием попеременного отрицательного давления, может быть использована при лечении гнойных ран, в том числе и в торакальной хирургии у пациентов, которым выполнена стернотомия.Осуществляется эффективное вакуумное дренирование ран с помощью устройства, которое состоит из герметичной раневой повязки, соединенного с контейнером для сбора раневого отделяемого и источником вакуума (создающего попеременное отрицательное давление) посредством порта вакуум-провода. Предварительно вакуум-провод располагают в толще пористой губки. Пористую губку укрывают со всех сторон пленкой из синтетического материала, которую перфорируют инъекционной иглой 21 G на всем протяжении, на 1 смнаносят от 6 до 9 отверстий. Расположения вакуум-провода в толще пористой губки обеспечивает равномерное, более эффективное дренирование раны, укрытие пористой губки пленкой из синтетического материала защищает ее от прорастания грануляционной тканью и при извлечении губки исключается риск возникновения кровотечения.

Полезная модель относится к области медицины, в частности к области нейрохирургии, и может быть использована для хирургического лечения пациентов с хроническими субдуральными гематомами.Разработанный нами субдуральный порт выполнен с учетом практики использования оригинального порта (патентный № US 7,553,290 В1 от 30.06.2009, А61М 1/00) и с учетом выявленных в ходе использования замечаний. Порт имеет резьбу на конце, предназначенном для завинчивания в полость черепа, с ограничителем. За ограничителем имеется болт под накидной ключ на 8 мм, что облегчает завинчивание порта в кости черепа и создает меньшие неудобства на перевязке. Кроме того, конец порта, предназначенный для соединения с закрытой системой, имеет резьбу для соединения с системой с переходником типа Люэр Лок (Luer Lock), что обеспечивает герметичность закрытия, а сама система предусматривает наличие трехходового катетера для ирригации и промывания гематомы, и имеется возможность контролировать создаваемое отрицательное давление позиционированием системы для сбора относительно головы пациента. 4 ил.

Полезная модель относится к области медицинской техники, в частности к устройствам для сбора слюны при самоистечении из полости рта в диагностических и медицинских целях. Заявляемая полезная модель позволяет максимально эффективно производить сбор слюны при самоистечении из полости рта в диагностических и медицинских целях. Техническим результатом является устранение недостатка прототипа, усовершенствование конструкции, позволяющее повысить эффективность сбора слюны для врача и пациента. Технический результат достигается за счет следующей совокупности существенных признаков: устройство для сбора слюны при самоистечении из полости рта (фиг. 1), представляет собой насадку с воронкообразным расширением из силикона (1) и ободом жесткости для фиксации губ (2), плотно фиксирующееся на пробирке для сбора слюны при помощи конической трубки (3). В отличие от прототипа у насадки наличие силиконового воронкообразного расширения и обода жесткости позволяет поместить губы пациента внутрь расширения, и слюна может свободно стекать в приемный сосуд, не вытекая из насадки. Заявляемая полезная модель является многоразовой, поэтому требуется стерилизация при многоразовом использовании. Устройство имеет следующие размеры: диаметр воронкообразного расширения 60 мм (1), обод жесткости 5 мм (2), угол при вершине в 30 градусов, длина конической трубки 20 мм (3), диаметр трубки в области воронкообразного расширения 15 мм, в свободной части - 8 мм. Данные размеры позволяют плотно установить устройство в приемном сосуде любого размера, и удобно разместить и зафиксировать губы для эффективного самоистечения слюны. Заявляемая полезная модель проста и удобна при взятии проб слюны при самоистечении из полости рта для диагностических и медицинских целей, может быть использована в процедурном кабинете или в домашних условиях.

Methods and systems for anticoagulating blood

Номер: US20120053501A1
Автор: Richard I. Brown
Принадлежит: Individual

Methods and systems are provided for anticoagulating blood. Whole blood is drawn from a donor into a system at a draw flow rate. Anticoagulant from an anticoagulant source is pumped into the system at an anticoagulant flow rate to mix with the blood. The anticoagulated blood may be subsequently processed in any of a number of known ways, including separating it and removing at least a portion of one of the components of the blood. Thereafter, at least a portion of the remaining blood may be returned to the donor. The anticoagulant flow rate is independent of the draw flow rate and can be based on a number of factors, including the weight of the donor and the rate at which the donor can metabolize the anticoagulant.

Fluid removal systems and methods for removing fluid from a tissue site are presented. The system includes a semi-permeable inbound conduit, which is fluidly coupled to a treatment-fluid delivery unit, for placement proximate to the tissue site, and a semi-permeable outbound conduit, which is fluidly coupled to the inbound conduit and to a treatment-fluid collector, for placement proximate to the tissue site of a patient. The treatment-fluid collector receives a treatment fluid and a recruited fluid from the tissue site. A recruited-fluid determination unit may be coupled to the treatment-fluid collector to determine a volume of fluid recruited from the patient. The treatment fluid is any fluid (including a gas) that pulls fluid from the interstitial and intracellular space.

Apparatus and associated methods for a wound valve assembly provide an annular space extending radially around a central portion of a valve, which valve acts to substantially relieve pressure build up in a thoracic cavity when applied to a thoracic wound. In an illustrative example, the valve assembly may form an annular space that extends radially in all directions around a check valve. In some examples, gasses and exudates may flow substantially radially and/or parallel to the patient's local body. Various embodiments may advantageously provide open fluid communication for the gasses and exudates escaping from the wound when the valve assembly is partially covered (e.g., body armor, clothing, blankets), or when the patient may be lying down on the side of the body with the wound, for example.

The present invention provides a breastshield for use in a breastpumping system for expressing milk, the breastshield being of such a construction that substantially limits the amount of air between the breast/nipple and the breastshield surrounding the breast/nipple, and most preferably virtually eliminates any air at least in the area of the breast and nipple. In some embodiments, any air in the breastpumping system is substantially eliminated. With the amount of air limited, the mechanism used for generating the pressure difference in the breastshield (e.g., vacuum or negative pressure), such as a diaphragm pump, does not need to do as much work. Less energy is required for the expression of milk, and thus the size of pump used can be decreased, thereby reducing the overall cost of the device. 1.
