Description

Test tube of flow cytometer

Technical Field

The application relates to the field of test tubes, in particular to a test tube of a flow cytometer.

Background

Flow cytometers are devices that automatically analyze and sort cells. The flow cytometry requires that the cell suspension is uniform before detection of the cell suspension, and no agglomeration phenomenon exists, so that a suction pipe of the flow cytometry cannot be blocked during sample loading, and therefore the cell suspension needs to be filtered before detection of the cell suspension, and the uniform cell suspension is obtained.

One common method of filtering cell suspensions is to filter through a filter membrane, which is placed in the mouth of a test tube and manually grasped prior to loading. The cell suspension is then passed through the filter and into a tube, thereby obtaining a filtered cell suspension.

In view of the above-mentioned related art, the inventors considered that there was a drawback that the filter was always held by hand when the cell suspension was filtered, which resulted in an excessive labor.

Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses flow cytometer's test tube, as shown in fig. 1 and fig. 2, including the body 1 of test tube, place ring 2, set up the filter membrane 3 in placing ring 2, the fixed solid fixed ring 4 that is provided with in mouth of pipe department of body 1, solid fixed ring 4 in this embodiment is the same with body 1 integrated into one piece, solid fixed ring 4 and body 1's mouth of pipe size.

As shown in fig. 2 and 3, when the worker adds the cell suspension, the worker holds the tube body 1 in hand, so that the tube body 1 is in the vertical direction, the tube opening of the tube body 1 faces upwards, the placing ring 2 is placed on the fixing ring 4, and the lower surface of the placing ring 2 contacts with the upper surface of the fixing ring 4. When placing ring 2 and placing on solid fixed ring 4, filter membrane 3 is located solid fixed ring 4, and the cell suspension directly adds and filters naturally on filter membrane 3, need not the staff and holds filter membrane 3 with the hand always and filters, reaches the effect that reduces staff's labour.

When filtering, the staff need not to go to tailor filter membrane 3, directly will place ring 2 and place and can filter on solid fixed ring 4, improve staff's work efficiency.

As shown in fig. 2 and 3, the pipe body 1 is sleeved with the stabilizing ring 5, the stabilizing ring 5 is fixedly provided with the contact block 6, the contact block 6 and the stabilizing ring 5 are integrally formed, the contact block 6 in the embodiment is in a circular ring shape, after the placing ring 2 is placed on the fixing ring 4, the stabilizing ring 5 is sleeved outside the fixing ring 4, the placing ring 2 is located in the stabilizing ring 5, and the outer side wall of the placing ring 2 is in contact with the inner side wall of the stabilizing ring 5. The stabilizing ring 5 can reduce the placing ring 2 to move, so that the placing ring 2 is stably placed on the fixing ring 4. The 5 covers of stabilizer ring from the top down establish on solid fixed ring 4 when, conflict 6 downside conflicts on placing ring 2, further reduces and places rocking of ring 2, reaches the effect of stably placing ring 2.

As shown in fig. 3 and 4, the stabilizing ring 5 is horizontally provided with an abdicating groove 7, the abdicating groove 7 in this embodiment has two notches, one notch is close to the placing ring 2, and the other notch is far from the placing ring 2. The middle inserting connection of the receding groove 7 is provided with a supporting rod 8, the supporting rod 8 supports the placing ring 2 tightly, a supporting component which is used for supporting the supporting rod 8 tightly towards one side of the placing ring 2 is arranged on the stabilizing ring 5, and the supporting component comprises a supporting ring 9, an anti-drop ring 10 and a telescopic spring 11. Anticreep ring 10 is fixed to be set up on keeping away from the notch of placing ring 2 one side, and conflict ring 9 is fixed to be set up on supporting pole 8, and expanding spring 11 cover is established on supporting pole 8, and expanding spring 11 one end is contradicted on anticreep ring 10, and the other end is contradicted on conflict ring 9.

As shown in fig. 3 and 4, under the conflict of expanding spring 11, support tight pole 8 and remove towards placing ring 2 one side to let support tight pole 8 support tightly and place ring 2, support tight pole 8 in this embodiment is provided with two, further stably place ring 2 and place. After the filtration of the cell suspension is finished, the placing ring 2 can be taken out simultaneously when the stabilizing ring 5 is taken out because the abutting rod 8 abuts against the placing ring 2. After the stabilizing ring 5 is taken out, the pulling supports the pole 8, lets support the pole 8 break away from and place the contact of ring 2 to let and place ring 2 and break away from stabilizing ring 5, reach the effect of conveniently taking out and placing ring 2.

As shown in fig. 2 and 4, the stabilizing ring 5 is provided with a stabilizing groove 12, and the tightening rod 8 is inserted into the stabilizing groove 12 after moving towards the placing ring 2, so as to further reduce the shaking of the placing ring 2. The fixed pull ring 13 that is provided with of 5 one ends of stabilizer ring is kept away from to the tighting pole 8, when the tighting pole 8 need be opened, can pull ring 13, and quick pulling tighting pole 8 lets the tighting pole 8 break away from and place the contact of ring 2.
