Abstract

A fluid-drive device includes a base, a fluid container, a pressing mechanism, and a rotation mechanism. The fluid container is disposed on the base. The pressing mechanism is disposed on the base, and configured to press the fluid container. The rotation mechanism is connected to the pressing mechanism. The pressing mechanism presses the fluid container by rotating the rotation mechanism. The fluid-drive device may guide the flow of the detection fluid in the fluid container in a non-contact manner to reduce the contamination of the fluid specimen and increase the reliability of the detection.

First claim

What is claimed is:

1. A fluid-drive device, comprising:
a base;
a fluid container disposed on the base;
a pressing mechanism disposed on the base, and configured to press the fluid container; and
a rotation mechanism connected to the pressing mechanism;
wherein the rotation mechanism is rotated so as to make the pressing mechanism press the fluid container,
wherein the fluid container comprises:
a fluid-guiding portion having a fluid channel;
a storage portion disposed on the fluid-guiding portion, and having a storage chamber in communication with the fluid channel;
an inspection portion disposed on the fluid-guiding portion, and having an inspection groove connected to the fluid channel;

wherein the pressing mechanism is configured to press the storage portion, and the storage chamber is configured to store detection fluid;
wherein when the storage portion is pressed by the pressing mechanism, the detection fluid of the storage chamber flows to the inspection groove via the fluid channel.

2. The fluid-drive device as claimed in claim 1 , wherein the pressing mechanism comprises:
a first rotation shaft connected to the base and the rotation mechanism; and
a first cam connected to the first rotation shaft, and configured to directly or indirectly press the fluid container;
wherein the first cam is rotated with the first rotation shaft by rotating the rotation mechanism.

3. The fluid-drive device as claimed in claim 2 , wherein the pressing mechanism further comprises a second cam connected to the first rotation shaft, and configured to directly or indirectly press the fluid container;
wherein the second cam is rotated with the first rotation shaft by rotating the rotation mechanism.

4. The fluid-drive device as claimed in claim 3 , wherein the first cam extends parallel to the second cam.

5. The fluid-drive device as claimed in claim 2 , wherein the pressing mechanism comprises:
a second rotation shaft connected to the base and the rotation mechanism;
a second cam connected to the second rotation shaft, and configured to directly or indirectly press the fluid container;
wherein the second cam is rotated with the second rotation shaft by rotating the rotation mechanism.

6. The fluid-drive device as claimed in claim 2 , wherein the pressing mechanism further comprises a pressing element movably disposed on the base, and located between the first cam and the fluid container, wherein the rotation mechanism is rotated so as to make the first cam move the pressing element, and to make the pressing element press the fluid container.

7. The fluid-drive device as claimed in claim 1 , wherein the rotation mechanism comprises:
a first connection plate connected to the pressing mechanism; and
a first handle connected to the first connection plate.

8. The fluid-drive device as claimed in claim 7 , wherein the rotation mechanism further comprises:
a second connection plate connected to the pressing mechanism;
a second handle connected to the second connection plate; and
a connection rod connected to the first handle and the second handle.

9. The fluid-drive device as claimed in claim 1 , wherein the storage portion further comprises a storage body, and a film disposed on a portion of the storage body, wherein the pressing mechanism is configured to press the film.

10. A fluid-drive device, comprising:
a base;
a fluid container disposed on the base;
a pressing mechanism disposed on the base, and configured to press the fluid container; and
a rotation mechanism connected to the pressing mechanism;
wherein the rotation mechanism is rotated so as to make the pressing mechanism press the fluid container,
wherein the rotation mechanism comprises:
a first connection plate connected to the pressing mechanism; and
a first handle connected to the first connection plate,
wherein the rotation mechanism further comprises:
a second connection plate connected to the pressing mechanism;
a second handle connected to the second connection plate; and
a connection rod connected to the first handle and the second handle.

11. The fluid-drive device as claimed in claim 10 , wherein the pressing mechanism comprises:
a first rotation shaft connected to the base and the rotation mechanism; and
a first cam connected to the first rotation shaft, and configured to directly or indirectly press the fluid container;
wherein the first cam is rotated with the first rotation shaft by rotating the rotation mechanism.

12. The fluid-drive device as claimed in claim 11 , wherein the pressing mechanism further comprises a second cam connected to the first rotation shaft, and configured to directly or indirectly press the fluid container;
wherein the second cam is rotated with the first rotation shaft by rotating the rotation mechanism.

13. The fluid-drive device as claimed in claim 12 , wherein the first cam extends parallel to the second cam.

14. The fluid-drive device as claimed in claim 11 , wherein the pressing mechanism comprises:
a second rotation shaft connected to the base and the rotation mechanism;
a second cam connected to the second rotation shaft, and configured to directly or indirectly press the fluid container;
wherein the second cam is rotated with the second rotation shaft by rotating the rotation mechanism.

15. The fluid-drive device as claimed in claim 11 , wherein the pressing mechanism further comprises a pressing element movably disposed on the base, and located between the first cam and the fluid container, wherein the rotation mechanism is rotated so as to make the first cam move the pressing element, and to make the pressing element press the fluid container.
