Fluid separation device and fluid separation method thereof

Abstract

The invention discloses a fluid separation device and a fluid separation method using the fluid separation device. The fluid separation device includes a body, a storage tank, a liquid inlet channel and a separation unit. A storage tank is formed in the center of the body. The liquid inlet channel is formed on the body and communicates with the storage tank. The separation unit is formed on the body and communicates with the liquid inlet channel. The separation unit includes a stacking area, a collecting area and a barrier wall. A collection area is located between the accumulation area and the storage tank. A barrier wall is formed between the collection area and the accumulation area.

Description

technical field [0001] The invention relates to a fluid separation device, in particular to a fluid separation device for separating blood. The invention also relates to a fluid separation method using the fluid separation device. Background technique [0002] The structure of the known fluid separation device is usually relatively complicated. For example, the fluid separation device disclosed in US Pat. No. 6,548,788 has a micro-valve design on the cassette to control the flow of fluid. However, since the micro-valve must be produced by micro-machining technology, the known fluid separation device cannot be produced by plastic injection molding, so the cost is relatively high. [0003] Similarly, US Pat. No. 5,061,381 and US 5,089,417 also disclose other forms of fluid separation devices, but their structures are too complicated, so the manufacturing cost is relatively high. Contents of the invention [0004] The present invention provides a fluid separation device for...

[0002] The structure of the known fluid separation device is usually more complex, such as the fluid separation device disclosed in US Patent No. 6,548,788, which has a micro-valve design on its cartridge to control the flow of fluid

However, since the micro-valve must be produced by micro-machining technology, the known fluid separation device cannot be produced by plastic injection molding, so the cost is relatively high

[0003] Similarly, U.S. Patent No. 5,061,381 and U.S. No. 5,089,417 also disclose other forms of fluid separation devices, whose structure is too complicated, so the manufacturing cost is relatively high
