Patent ID: 11946034
Assignee: NIHON KOHDEN CORPORATION
Field: Measurement (Instruments)
Classification: CPC C  G | IPC C  G

Claim 0:
1. A sterile sampling apparatus comprising:
a first flow path configured to be connected to a first tank for accommodating a culture medium containing cells;
a second flow path configured to be connected to a second tank for accommodating a buffer solution;
a third flow path configured to communicate with ambient air:
a fourth flow path includes a first branch portion where the second flow path and the third flow path are configured to be joined together;
a fifth flow path includes a second branch portion where the first flow path and the fourth flow path are configured to be joined together;
a sixth flow path configured to branch off from a third branch portion which is downstream of the fifth flow path;
a seventh flow path configured to branch off from the third branch portion; and
a sampling section configured to be disposed in the seventh flow path,
wherein a first pump that sends a fluid in the sixth flow path is disposed in the sixth flow path,
wherein a second pump that sends a fluid in the seventh flow path is disposed in the seventh flow path,
wherein the second flow path includes a first opening/closing mechanism,
wherein the third flow path includes a second opening/closing mechanism,
wherein the fourth flow path includes a third opening/closing mechanism,
wherein the first flow path includes a fourth opening/closing mechanism,
wherein the sixth flow path includes a fifth opening/closing mechanism,
wherein the seventh flow path includes a sixth opening/closing mechanism,
wherein the apparatus operates in a manner that, in a case where the first opening/closing mechanism is opened, the second opening/closing mechanism is closed, or, in a case where the second opening/closing mechanism is opened, the first opening/closing mechanism is closed,
wherein the apparatus operates in a manner that, in a case where the third opening/closing mechanism is opened, the fourth opening/closing mechanism is closed, or, in a case where the fourth opening/closing mechanism is opened, the third opening/closing mechanism is closed,
wherein the apparatus operates in a manner that, in a case where the fifth opening/closing mechanism is opened, the sixth opening/closing mechanism is closed, or, in a case where the sixth opening/closing mechanism is opened, the fifth opening/closing mechanism is closed, and
wherein a rate at which the fluid is sent by the second pump is higher than a rate at which the fluid is sent by the first pump.
