Methods of separating, identifying and dispensing specimen and device therefor, and analyzing device method
A specimen sorter includes a separating device to remove a specimen from a container, a detection device to identify the specimen as a target specimen or a non-target specimen, and a dispensing device to dispense the specimen. The dispensing device includes a dispensing nozzle to contact a vibration member to form liquid droplets at a front end of the dispensing nozzle and to dispense the liquid droplets, a first container to collect the liquid droplets dispensed from the dispensing nozzle that contain the target specimen, and a second container to collect the liquid droplets dispensed from the dispensing nozzle that contain the non-target specimen.
1. A specimen sorter, comprising:
a separating device to remove a specimen from a container;
a detection device to identify the specimen as a target specimen or a non-target specimen; and
a dispensing device to dispense the specimen, the dispensing device comprising:
a dispensing nozzle and a vibration member, wherein one of the dispensing nozzle and the vibration member moves relative to the other of the vibration member and the dispensing nozzle from a position in which the dispensing nozzle is not in contact with the vibration member to a position in which the dispensing nozzle and the vibration member collide to form liquid droplets at a front end of the dispensing nozzle and to dispense the liquid droplets;
a first container to collect the liquid droplets dispensed from the dispensing nozzle that contain the target specimen; and
a second container to collect the liquid droplets dispensed from the dispensing nozzle that contain the non-target specimen.
2. The specimen sorter according to claim 1 , wherein the dispensing device further comprises:
a driving device to move the first container and the second container to collect the liquid droplets.
3. The specimen sorter according to claim 1 , wherein the dispensing device further comprises:
a third container to collect the liquid droplets dispensed from the dispensing nozzle that contain the target specimen; and
a fourth container to collect the liquid droplets dispensed from the dispensing nozzle that contain the non-target specimen.
4. The specimen sorter according to claim 3 , wherein the dispensing device further comprises:
a driving device to move the first container, the second container, the third container, and the fourth container to collect the liquid droplets.
5. The specimen sorter according to claim 1 , wherein the liquid droplets in the dispensing nozzle are formed by a predetermined vibration generated when the dispensing nozzle and the vibration member collide.
6. The specimen sorter according to claim 1 , wherein the nozzle includes a front end member at the front end of the nozzle, and the vibration member is moved to collide with the front end member.
7. The specimen sorter according to claim 1 , wherein the vibration member is moved to collide with the nozzle to form the liquid droplets.
8. The specimen sorter according to claim 1 , wherein the nozzle is moved to collide with the vibration member to form the liquid droplets.
9. The specimen sorter according to claim 1 , wherein the vibration member includes two side members, and the dispensing nozzle is shook between the side members to collide with the side members alternately one after another.
10. A method of sorting a specimen, comprising:
removing a specimen from a container;
identifying the specimen as a target specimen or a non-target specimen; and
dispensing the specimen, the dispensing the specimen comprising:
forming liquid droplets at a front end of a dispensing nozzle by moving one of the dispensing nozzle and a vibration member relative to the other of the vibration member and the dispensing nozzle from a position in which the vibration member is not in contact with the dispensing nozzle to a position in which the vibration member and the dispensing nozzle collide;
dispensing the liquid droplets from the dispensing nozzle;
collecting, in a first container, the liquid droplets dispensed from the dispensing nozzle that contain the target specimen; and
collecting, in a second container, the liquid droplets dispensed from the dispensing nozzle that contain the non-target specimen.
11. The method according to claim 10 , wherein the dispensing further comprises:
moving the first container and the second container to collect the liquid droplets.
12. The method according to claim 10 , wherein the dispensing further comprises:
collecting, in a third container, the liquid droplets dispensed from the dispensing nozzle that contain the target specimen; and
collecting, in a fourth container, the liquid droplets dispensed from the dispensing nozzle that contain the non-target specimen.
13. The method according to claim 12 , wherein the dispensing further comprises:
moving the first container, the second container, the third container, and the fourth container to collect the liquid droplets.
14. The method according to claim 10 , wherein the forming the liquid droplets in the dispensing nozzle includes generating a predetermined vibration to form the liquid droplets when the dispensing nozzle and the vibration member collide.
15. The method according to claim 10 , wherein the forming liquid droplets includes moving a vibration member to collide with a front end member at the front end of the nozzle.
16. The method according to claim 10 , wherein the forming the liquid droplet includes moving the vibration member to collide with the nozzle to form the liquid droplets.
17. The method according to claim 10 , wherein the forming the liquid droplet includes moving the nozzle to collide with the vibration member to form the liquid droplets.
18. The method according to claim 10 , wherein the forming liquid droplets further comprises:
shaking the dispensing nozzle between two side members of the vibration member so that the dispensing nozzle collides with the side members alternately one after another.
