Embodiment Construction

[0067] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0068] Such as Figure 1 to Figure 9 As shown, the present invention provides a kind of variable capacity sucking device, and it comprises suction pipe 1, the suction head 2 that communicates with one end of suction pipe 1, the linear motor 3 that is connected with the other end of suction pipe 1, the stator 31 of linear motor 3 is inserted into In the suction pipe 1 , the stator 31 is driven by the linear motor 3 to move along the axial direction of the suction pipe 1 , and the suction pipe 1 is also connected to the vacuum pipe joint 4 .

[0069] In this suction device, the suction head 2 is connected with the suction port 201 of the cryopreservation tube storage container 20. After the vacuum pipe joint 4 is connected with the vacuum pumping tube, a negative pressure is generated in the suction tube 1 by pumping air, so that ...

Abstract

The invention provides a variable-volume suction device. The variable-volume suction device comprises a suction tube, a suction head communicating with one end of the suction tube, and a linear motor connected with the other end of the suction tube. A stator of the linear motor is inserted into the suction tube. The stator is driven by the linear motor to move in the axial direction of the suction tube. The suction tube also communicates with a vacuum tube connector. The variable-volume suction device is a novel freezing storage tube suction device, the number of freezing storage tubes sucked by the suction tube every time is limited by adjusting the length of the stator stretching into the suction tube so that the number of freezing storage tubes sucked every time can be set, and different suction requirements can be met.

Description

technical field [0001] The invention relates to a variable volume suction device. Background technique [0002] At present, the storage and withdrawal of biological sample cryopreservation tubes has been automated, and vacuum suction is a common way to take tubes. Since each batch needs to take several cryopreservation tubes, and the quantity is not fixed, if you draw one by one, the efficiency is low; if you want to draw more than one at a time, the commonly used fixed-length straws can only absorb a fixed number of cryopreservation tubes each time , unable to adapt to the uncertain demand of taking tubes in each batch. [0003] At the same time, in order to ensure the activity, biological samples are often stored in a deep low temperature environment; and when the tube is taken out, the sample will be exposed to room temperature, and drastic changes in temperature will cause damage to the biological sample. Contents of the invention [0004] In order to solve the techn...
