no. 1 approach

[0103] like figure 1 , figure 2 as well as image 3 As shown, the solution transfer apparatus of the first embodiment includes a pump 60 and a substrate 70 . The solution transporting device may include a plurality of pumps 60 . In addition to the pump 60 shown in the figure, the solution transport device may include a plurality of pumps not shown.

[0104] like Figure 4 to Figure 7 As shown, the pump 60 is a tube pump, and the pump 60 is provided with: a tube 1 for flowing a solution; tube rotors 21A, 21B, 21C, which are in contact with the tube 1; The tube rotors 21A, 21B, and 21C are rotated in such a manner that 21B and 21C are in contact, and are used to transport the solution in the tube 1 . The solution contains, for example, cells.

[0105] Examples of cells include somatic cells, but are not particularly limited. Examples of cells include fibroblasts, nerve cells, retinal epithelial cells, hepatocytes, beta cells, kidney cells, blood cells, dental pulp stem c...

no. 2 approach

[0143] like Figure 9 to Figure 12 As shown, the tube 1 of the pump 60 and the tube rotor 21 may be arranged in the base plate 70 . In addition, the tube 1 that houses the pump 60 and the casing 3 of the tube rotor 21 may be arranged in the base plate 70 . Alternatively, the housing 3 may be omitted. In the base plate 70, at least a part of the tube 1 is arranged as a ring-shaped part. The inside of the base plate 70 may be provided with a concave portion that accommodates, for example, the tube 1 , the tube rotor 21 , and the transmission rotor 5 . The drive device 10 disposed outside the base plate 70 can rotate the tube rotor 21 inside the base plate 70 by magnetic force. The other constituent elements of the solution transporting device of the second embodiment are the same as those of the solution transporting device of the first embodiment, for example.

no. 3 approach

[0145] like Figure 13 as well as Figure 14 As shown, the pump 60 may include light reflecting portions 7A, 7B, and 7C connected to at least a part of the tube rotors 21A, 21B, and 21C. The light reflection parts 7A, 7B, and 7C reflect light. For example, the light reflection parts 7A, 7B, and 7C are arranged at equal intervals on the circumference. The light reflection parts 7A, 7B, and 7C may be arranged on the tube rotor holding member 9 that holds the tube rotors 21A, 21B, and 21C. The tube rotor holding member 9 can rotate with the rotation of the tube rotors 21A, 21B, and 21C. In addition, the pump 60 may include a light source for irradiating the light reflecting parts 7A, 7B, and 7C with light from outside the casing 3, and a light receiving part for receiving the reflected light from the light reflecting parts 7A, 7B, and 7C. The light receiving unit converts the received reflected light into an electrical signal. The light source and the light receiving unit ma...

Abstract

A solution transport device is provided with a pump (60) provided with a tube (1) through which a solution flows, tube rotors (21A, 21B, 21C) that come into contact with the tube (1), and a drive device (10) for transporting the solution in the tube (1) while rotating the tube rotors (21A, 21B, 21C) without coming into contact with the tube rotors (21A, 21B, 21C), and a substrate (70) provided with a flow path connected to the tube (1) of the pump (60). And a solution can flow through the flow channel.

Description

technical field [0001] The present invention relates to a solution delivery device. Background technique [0002] Pumps are used to transport fluids as liquids and gases. Pumps that are in direct contact with the fluid being handled may cause contamination in the fluid. Therefore, in the case where contamination by the fluid is not desired, a tube pump capable of transporting the fluid in the tube without directly contacting the fluid is applied (for example, refer to Patent Documents 1 and 2). The tube pump includes a rotating part that rotates while pressurizing the tube. The cross-sectional area of ​​the pressurized portion of the tube is reduced. Because the pressurized portion of the tube moves with the rotation of the swivel, the fluid within the tube moves towards the direction of rotation of the swivel.
