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-capacity suction device, which includes a suction pipe, a suction head connected to one end of the suction pipe, and a linear motor connected to the other end of the suction pipe. The stator of the linear motor is inserted into the suction pipe, and the stator is driven by the linear motor. Move along the axial direction of the suction pipe, and the suction pipe is also connected with the vacuum pipe joint. This variable capacity suction device provides a new type of cryopreservation tube suction device. By adjusting the length of the stator extending into the suction tube, the number of cryopreservation tubes that the suction tube can absorb at one time is limited, so that the number of cryopreservation tubes drawn each time can be adjusted. Settings, can adapt to a variety of different suction needs.

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...
