Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clear, embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

As shown in fig. 1 to 3, the present invention provides a cold storage tube for immune cells, which includes an outer tube 1, an inner tube 2 disposed inside the outer tube 1, and the inner tube 2 for storing immune cells. The immune cell in the cold storage pipe need freeze under low temperature environment and deposit, for avoiding the immune cell to lead to the cell to freeze too fast because the temperature dip, the inside moisture of cell can't be discharged to produce the ice crystal and damage the cell, the cold storage pipe in this embodiment is divided into outer tube 1 and inner tube 2, through such setting, can delay the cooling speed, avoids damaging the immune cell because the temperature dip. The top of the outer tube 1 is provided with a tube cap 3, the tube cap 3 is in threaded connection with the outer surface of the outer tube 1, a threaded through hole 4 is formed in the center of the top of the tube cap 3, a threaded rod 5 is connected to the inner thread of the threaded through hole 4, a rotary handle 6 is fixedly connected to the top end of the threaded rod 5, a rubber plug 7 is fixedly connected to the bottom end of the threaded rod 5, and the size of the rubber plug 7 is matched with the inner diameter of the inner tube 2. During the use, at first make tube cap 3 and outer tube 1 pass through threaded connection, then rotation turning handle 6 drives threaded rod 5 and moves down, and then rubber buffer 7 gets into and seals inner tube 2 among the inner tube 2, through the secondary seal to inner tube 2, can improve the leakproofness of cold storage pipe, prevents that the condition of damage can appear in the long-time back screw thread of using, influences the quality of cold storage intraductal immune cell. A damping component is arranged between the outer pipe 1 and the inner pipe 2, and the outer surface of the outer pipe 1 is provided with scale marks 8.

Further, fixedly connected with first stopper 9 and second stopper 10 on the outer tube 1 lateral wall internal surface, fixedly connected with connecting rod 11 of the vertical setting of fixedly connected with between first stopper 9 and the second stopper 10, and fixedly connected with connecting plate 12, connecting plate 12 and connecting rod 11 sliding connection that the level set up on the 2 lateral wall surface of inner tube.

Further, damper includes a plurality of first fixed blocks 13 and a plurality of second fixed blocks 14, and first fixed block 13 fixed connection is on the surface of inner tube 2 bottom, and second fixed block 14 fixed connection is on the internal surface of outer tube 1 bottom, and first fixed block 13 and second fixed block 14 one-to-one are provided with first spring 15 between first fixed block 13 and the second fixed block 14. When the cold storage pipe is vibrated, the inner pipe 2 can be prevented from generating large deflection under the buffering action of the first spring 15.

Further, the part cover that connecting rod 11 is located between first stopper 9 and connecting plate 12 is equipped with second spring 16, and when the cold storage pipe received vibrations, inner tube 2 moved down, and first spring 15 is further compressed, sets up second spring 16 and can prevent that inner tube 2 from producing great vibrations because of restoring to the throne too fast.

Further, outer tube 1 bottom is provided with rubber suction cup 17, and through setting up rubber suction cup 17, the cold storage tube can steadily adsorb on the test bench desktop, and the staff of being convenient for adds the immune cell to the cold storage tube.

Further, 3 tops of tube caps are provided with apron 18, and apron 18 is connected with 3 tops locks of tube caps, is provided with identification code 19 on the internal surface of 18 tops of apron, and identification code 19 is used for distinguishing sample information, and identification code 19 is the bar code, and the bar code sets up on 18 tops internal surfaces of apron through modes such as pasting, has avoided identification code 19 to set up the problem that drops easily because of the low temperature on the body.

Further, apron 18 is transparent material, and the cold storage pipe is generally all placed and is kept cold in cold storage plant, and apron 18 sets up to transparent material then the staff need not take off apron 18 and just can distinguish sample information, convenient operation through scanning the bar code.

Further, the outer wall of the tube cover 3 is provided with anti-skid grains 20. By arranging the anti-slip threads 20, the pipe cover 3 can be screwed or unscrewed conveniently by workers.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model.
