Disclosed are devices, systems, and methods for self-constructing structures. In particular, a mold for forming a structure includes an inflatable inner balloon, a non-inflatable outer shell coupled to the inner balloon about a base circumference, the outer shell having an apex and an opening disposed at the apex, and a pump in fluid communication with the opening of the outer shell; wherein, when the inner balloon is inflated, a gap is formed between the inner balloon and the outer shell for containing a building material, and the outer shell comprises a dome shape.

A disposable blood separation set and a centrifugal blood processing system comprising a blood processing chamber adapted to be mounted on a rotor of a centrifuge; a frustro-conical cell separation chamber in fluid communication with the processing chamber, the cell separation chamber having an inlet, an outlet and a gravity valve inside the cell separation chamber. The valve is responsive to the gravitational field created by the speed of the rotor. When the rotor spins at high speed, the gravity valve may open the outlet at a location proximal to an axis of rotation of the rotor. When the rotor spins at a lower speed, the gravity valve may open the outlet at a location distal from the axis.

An apparatus (10) for removing particulates from a fluid is described. The apparatus (10) includes a rotatable vessel (12) for receiving a dirty fluid containing the particulates in suspension, the vessel (12) having a plurality of side walls (14) arranged to form a polygonal cross-sectional shape in a plane orthogonal to an axis of rotation of the vessel. The vessel (12) has a fluid inlet port (16) through which the dirty fluid enters the vessel, and a fluid outlet port (18) through which a clean fluid exits the vessel after removal of particulates.The apparatus (10) also comprises a solids discharge port (20) provided at each of the vertices of the polygonal cross-section wherein, in use, when the vessel is rotated the particulates in the fluid entering the vessel (10) migrate to the vertices, from where they can be discharged through the discharge ports.
摘要:
A laboratory apparatus that is readily adapted to execute a wide range of sample preparation protocols is a set forth. The laboratory apparatus comprises a plurality of tools that are adapted to execute one or more processes in preparing a sample for subsequent analysis and a hollow rotor that is mounted for rotation about a rotation axis. A septum divides the hollow rotor into first and second chambers. Both the first and second chambers are accessible to one or more of the plurality of tools. One or more valve mechanisms are disposed to control fluid communication between the first and second chambers based, at least in part, on the rotation rate imparted to the hollow rotor.

Embodiments relate to systems, chambers, and methods for processing particles by washing, concentrating, and/or treating the particles. Some embodiments provide for the processing of cells that may be in a liquid medium (e.g., a liquid in which the cells were grown) and are processed by being washed and concentrated for later use in research or other therapies.

미소입자 처리 장치는 기판 및 적어도 하나의 유로를 포함한다. 상기 기판은 중심 영역을 가지며, 상기 중심 영역에 대하여 회전 가능하다. 상기 유로는 상기 기판에 구비되어 상기 중심 영역으로부터 반경 방향으로 연장하며, 상기 기판의 회전에 의한 원심력을 사용하여 미소입자를 포함하는 유체를 입력 단부로부터 출력 단부로 이송시킨다. 상기 유로의 상기 입력 단부와 상기 출력 단부 사이에 상기 미소입자를 포획하기 위한 가변적 단면 형상들을 갖는 포획 영역이 형성된다.
摘要:
The invention relates to methods and apparatus for recovery of cells from a tissue sample using a single container for processing and separation of tissue and cells. The processing unit comprises a processing compartment having a processing side wall; at least one wash fluid compartment having a washing side wall, wherein the wash fluid compartment is located radially outside of the processing compartment and separated by the processing side wall, wherein a first opening is formed at the top of the processing side wall to allow fluidic communication between the processing compartment and the wash fluid compartment; and at least one concentration compartment, wherein the concentration container is located radially outside of the wash fluid compartment and separated by the washing side wall, wherein a second opening is formed at the top of the washing side wall to allow fluidic communication between the wash fluid compartment and the concentration compartment.
摘要:
An apparatus for separating a volume of composite liquid into at least a first component and a second component comprises a centrifuge having a rotor (32, 33, 34, 35). The rotor comprises a turntable (35) for supporting a separation bag (1) and a central compartment (34) for containing satellite bags connected to the separation bag (1). The central compartment is fitted with a support member (87) for supporting at least one satellite bag (2, 3) so that a liquid contained in the supported satellite bag (2, 3) drains from the supported satellite bag (2, 3) into the separation bag (1) under centrifugation forces when the rotor (32, 33, 34, 35) is set in rotation.
