Benefits of technology

The patent is about a system for filtering biological fluids. It includes a device for receiving the fluid and a valve that can direct it through either one or two outlets based on the information scanned from the fluid. The system can filter out unwanted substances from the fluid and help improve its quality. The patent is not limited to the specific details given and can be applied to different embodiments and arrangements.

Problems solved by technology

Thus, rarity is a significant challenge for the identification and separation of CTCs and CTC-clusters.
Furthermore, some CTCs overlap in size with white blood cells, making size based separation challenging.

Embodiment Construction

[0066]A. Overview.

[0067]An example biological fluid filtration system 10 generally comprises a receiver path 20 adapted to receive a biological fluid 16 from a biological fluid source 17. The receiver path 20 may comprise various types of conduits, channels, or the like known in the art for transferring a fluid between two locations such as, for example, an apheresis catheter, an indwelling line, or a venous catheter. Other examples could include two intravenous (IV) lines: one for access to an artery and the other for access to a vein. The systems and methods described herein may be utilized for filtering a wide range of biological fluids 16, such as but not limited to blood, lymphatic fluid, cerebrospinal fluid, sweat, urine, pericardial fluid, stools, saliva, and the like. The biological fluid source 17 may comprise the patient 12 herself or, in some embodiments, a separate reservoir in which the biological fluid 16 is temporarily stored after being drawn from the patient 12.

Abstract

A biological fluid filtration system for scanning a biological fluid so as to filter potentially undesirable constituents from the biological fluid for therapeutic or diagnostic purposes. The biological fluid filtration system generally includes a fluid receiving device adapted to receive a biological fluid. A valve including an inlet, a first outlet, and a second outlet is fluidly connected to the fluid receiving device. The biological fluid within the fluid receiving device is scanned by a scanner to produce scanned data relating to the biological fluid. A control unit in communication with the scanner and the valve receives the scanned data and controls the valve based on the scanned data. The valve is controlled to direct the biological fluid through either the first or second outlet of the valve depending upon the constituents of the biological fluid identified by the control unit.
