- the spatial addressing of the analysis site may be preceded by mounting an image sensor device on the slider 211 before reading the analysis site, by radial search and azimuthal search.
- 9 and 10 show one embodiment of a liquid valve to prevent leakage of liquid during centrifugation.
- the liquid valve (7) is a high-speed rotation of the body 100, the serum contained in the sample chamber 131a to move to the analysis site 132 by the English alphabet V-shaped or U-shaped channel (7) prevent.
- 9 and 10 are detailed views of the liquid valve implemented by the liquid valve 7.
- the liquid valve 7 is largely divided into an inward channel 7a and an outward channel 7b.
- the inward channel 7a refers to a channel formed in the central direction of the body (the direction opposite to the centrifugal force), and the outward channel 7b refers to a channel formed in the centrifugal force direction.
- the operation of the liquid valve 7 is as follows.
- liquid leaked out from the sample chamber 131a is first filled in the inward channel 7a. Once the leaked liquid fills the inward channel 7a, the radial direction centrifugal force acts on the leaked liquid itself within the inward channel 7a so that the liquid in the sample chamber 131a is no longer present. Leaks are detained. Rather, the leaked liquid is withdrawal back into the sample chamber 131a by centrifugal force. That is, at the high speed of rotation of the body 100, when a part of the liquid has escaped from the sample chamber 131a, the centrifugal force acting on the liquid itself causes a force to be further leaked from the sample chamber 131a and the liquid that has already leaked. The balance of forces between the acting centrifugal forces prevents further liquid leakage. Preventing leakage of liquid by centrifugal force acting on such already leaked liquid is called liquid valve operation in one embodiment of the present invention.
- the outlet of the sample chamber 131a may further include a liquid valve for preventing the leakage of liquid during centrifugation.
- the liquid valve comprises a V-shaped or U-shaped flow path or one implemented by a superhydrophilic coated flow path causing a liquid valve action.
- FIG. 11 is a diagram illustrating the periphery of the sample chamber 131a and the residue chamber 131b in the thin film centrifuge device 100 of FIG. 2 to explain the centrifugation process.
- FIG. 11 illustrates a step of separating blood and blood cells from the sample chamber 130 into the sample chamber 131a and the residue chamber 131b by the rotation of the body 100 into serum and red blood cells by centrifugation.
- step 1 during the initial rotation of the body, the blood is moved from the sample chamber 130 to the sample chamber 131a and the ground chamber 131b, and the blood exceeding the height of the metering flow passage 93 is subjected to the centrifugal force. The movement to the surplus chamber 131c is shown. It also shows that the blood cannot be moved to the analysis site 132 by the liquid valve 7 and is retained in the sample chamber 131a.
- Step 2 shows the intermediate state of the centrifugation, and the centrifugation is performed independently for each blood stored in the sample chamber 131a and the residue chamber 131b by centrifugal force according to the rotation of the body, thereby separating serum and red blood cells.
- the red blood cells in the sample chamber 131a are left in the ground chamber 131b through the bottleneck channel 67. Go to.
- the serum centrifuged in the residue chamber 131b moves into the sample chamber 131a through the bottleneck channel 67.
- the bottleneck channel 67 may provide a passage through which serum and red blood cells separated during centrifugation can freely move between the sample chamber 131a and the ground chamber 131b. Since the residue chamber 131b is disposed on the outer side of the circumference more than the sample chamber 131a, red blood cells are collected in the residue chamber 131b and serum is collected in the sample chamber 131a as the centrifugation progresses. Step 3 shows that the serum is collected in the sample chamber 131a and the red blood cells are collected in the debris chamber 131b while the centrifugation is completed by the step 2. Step 4 indicates that the serum of the sample chamber 131a is hydrophilically moved to the analysis site 132 through the liquid valve 7 when the rotation of the body is stopped after the centrifugation is completed.
- Step 5 shows that only the quantitative serum in the sample chamber 131a has moved to the assay site 132. That is, only the quantitative serum moves into the assay site 132 and the fluid in the bottleneck channel 67 and the residue chamber 131b does not move to the assay site 132 and remains intact.
- the amount of serum that moves to the assay site 132 is determined by the amount of serum stored in the sample chamber 131a.
- This phenomenon may be due to the following five causes.
- the bottleneck channel 67 As a thin film flow channel (channel), a strong capillary phenomenon acts on the fluid during the stop of the body, so that the fluid in the ground chamber 131b passes through the bottleneck channel 67 to the sample chamber 131a. Do not move. Therefore, the red blood cells in the residue chamber 131b can be prevented from moving into the sample chamber 131a. Since the ground chamber 131b is configured as a capillary chamber, the red blood cells stored in the ground chamber 131b are hard to escape. The red blood cells are hardly freed from the ground chamber 131b due to the binding force between the surface of the ground chamber 131b and the red blood cells.
- the red blood cells stored in the residue chamber 131b are difficult to move because the bottleneck channel 67 is blocked by the viscosity of the serum. Since the ground chamber 131b does not have a dedicated exhaust port thereof, the red blood cells stored in the ground chamber 131b are difficult to move.
- FIG. 12 illustrates one embodiment of the bottleneck channel 67 above.
- the detailed figure shows a cross section of the bottleneck channel 67 by the baseline connecting baseline identification numbers 67a and 67b.
- the bottleneck channel 67 is a first thin film adhesive tape 1a for bonding the upper substrate 1 and the middle substrate 2 and a second thin film adhesive tape for bonding the intermediate substrate 2 and the lower substrate 3. It consists of two thin film flow paths formed by (2a).
- the bottleneck channel 67 formed by these two thin-film flow paths allows red blood cells in the sample chamber 131a to move to the residue chamber 131b or freely move serum in the residue chamber 131b to the sample chamber 131a during centrifugation.
- the bottleneck channel 67 may serve as a bottleneck channel for preventing fluid movement when the body is stopped, and may provide a passage for moving serum and red blood cells during centrifugation.
