摘要： A blood collection vessel includes a blood inlet, a pooling region in which blood from the inlet collects, and an outlet in the pooling region for reinfusion of the collected blood. A filter located in the blood path between inlet and outlet extends at least in part into the pooling region and impounds clots so they remain away from the outlet but suspended in the collected blood. Preferably, the filter is located to provide venting between both sides of the filter. In one embodiment the filter is a vertical wall, which defines a shielded outlet column or chimney extending above the outlet. Blood permeates to the outlet region over a broad area, and the column forms an open suction path that prevents suction differentials from arising across the filter, so clots cannot be sucked through the large-pore material. With the clots residing in the collected fluid, the total fluid loss is directly displayed in a single window at all times, and maximal use is made of the limited volume in the vessel. In another embodiment, the filter constitutes a false floor or basket in the pooling region. A preferred construction employs filter material on a support grid, to form a flexible and self-supporting filter sheet, which inserts like a plate to compartmentalize the collection vessel and form an impounding surface in the pooling region.
摘要翻译： 血液采集容器包括血液入口，来自入口的血液收集的汇集区域以及汇集区域中用于回收血液回输的出口。 位于入口和出口之间的血液路径中的过滤器至少部分地延伸到汇集区域中并扣留凝块，使得它们保持远离出口但悬浮在收集的血液中。 优选地，过滤器被定位成在过滤器的两侧之间提供排气。 在一个实施例中，过滤器是垂直壁，其限定在出口上方延伸的屏蔽出口塔或烟囱。 血液在大面积上渗透到出口区域，柱形成一个开放的吸入路径，防止吸入差异跨越过滤器，因此凝块不能通过大孔材料吸入。 在收集的液体中存在凝块的情况下，总的流体损失始终直接显示在单个窗口中，并且最大限度地利用了容器中有限的体积。 在另一个实施例中，过滤器构成汇集区域中的假地板或篮子。 优选的结构是在支撑格栅上使用过滤材料，以形成柔性和自支撑的过滤片，其将类似板的插入物分隔成收集容器并在汇集区域中形成蓄水表面。

摘要： A fluid recovery system, such as a chest or thoracic cavity drain, having a collection chamber for collecting fluid from a patient includes a base and a front face having a translucent portion for viewing the collected fluid and monitoring operation of the system. The front face is coupled to the base at an acute angle to facilitate viewing of the collected fluid, and measurement of the fluid volume, from a position substantially above the fluid recovery system. Additionally, a column insert can be positioned within the collection chamber to collect an initial volume of the fluid and to allow precise determination of its volume.

摘要： An apparatus is provided for indicating the presence of pressure within a collection chamber of a device such as a chest drainage device. The apparatus includes a bladder configured to be positioned within the collection chamber or within another chamber in fluid flow communication with the collection chamber. The bladder has a concavity formed therein and configured to contract or expand in response to pressure in the collection chamber. The apparatus also includes surfaces associated with the bladder that are configured to move with respect to one another upon contraction or expansion of the concavity of the bladder, thereby indicating pressure within the collection chamber.

摘要： A valve for use in a chest drainage device is disclosed, the chest drainage device is adapted to receive liquid and air from a patient's chest cavity via an inlet and to permit air to escape through an outlet for air to leave the chest drain, the inlet and outlet define a flow path and the valve is disposed along the flow path. The valve has a valve element that separates an upstream chamber from a downstream chamber and has a first and second sealing surface that are opposed so that when the first and second sealing surfaces are in contact, air pressure below a predetermined value will be prevented from moving from the downstream location to the upstream location. The valve element allows air to move from the upstream chamber to the downstream chamber at a low pressure differential. A pressure relief actuating element is disposed in the valve and located adjacent the valve element such that when the predetermined sub-atmospheric pressure limit between the upstream side and the downstream side is reached or exceeded, the valve element deforms and contacts the pressure relief actuating element such that the post causes the first and second sealing surfaces to partially separate and reduce the pressure differential.

摘要： A chest drainage system includes a collection device and a fluid pathway configured to extend from the collection device to a patient. The fluid pathway has a proximal portion configured to extend proximally toward the patient and a distal portion configured to extend distally from the patient. The chest drainage system also includes a pressure source including an accumulator configured to selectively provide sub-atmospheric pressure to the distal portion of the fluid pathway and a valve configured to selectively relieve pressure in the proximal portion of the fluid pathway. The system is configured to open the valve and to introduce the sub-atmospheric pressure from the accumulator of the pressure source when a predetermined pressure differential is detected between the proximal and distal portions of the fluid pathway.
