When the utility model is in use:

After extracting the bone marrow specimen from the human body and injecting it into the specimen vial, open the cover on the top of the shell 1, and insert the specimen vial into any opening of the small carrier box 2 or the large carrier box 3 obliquely, so that the outer wall of the specimen vial is tightly closed. Adhere to the tongue plate 21, and at the same time, the rubber ring 22 is stuck on the outer wall of the sample vial so that it cannot move freely. At this time, a constant temperature water flow circulates in both the small carrying box 2 and the large carrying box 3 . The constant temperature water flow can ensure that the specimen in the specimen test tube bottle is kept in a constant temperature state.

It should be noted that, one end of the rubber water pipe connected between the small carrying box 2 and the large carrying box 3 should be inserted from the top surface of the small carrying box 2 and extend below the inner water surface of the small carrying box 2, and the other end should be inserted from the top of the large carrying box 3. The surface is inserted into and away from the water surface of the large carrying box 3, and the rubber water pipe connected between the large carrying box 3 and the water tank 6 is also the same. The reason is that the water circulation in this scheme utilizes the siphon principle. Siphoning is the use of the force phenomenon of the liquid level difference. After filling the liquid into an inverted U-shaped tubular structure, the end with the high opening is placed in a container filled with liquid. Low position outflow. In this scheme, the water flow flows from the small carrying box 2 at the high level to the large carrying box 3 at the low level until the water level in the small carrying box 2 is lower than the mouth of the rubber pipe, at which point the flow stops, Until the water pump 5 pumps the water in the water tank 6 into the small carrying box 2 until it does not pass the nozzle of the rubber pipe, the siphon action is repeated, and the water flow between the large carrying box 3 and the water tank 6 is the same.

In addition, it should be noted that the tray 4 can be regularly and continuously swayed by the shaking part 41 and the motor 43, which can fully mix the specimen and the culture solution in the specimen vial, and further ensure that the specimen remains alive for a long time. The rocking part 41 includes a driving wheel 411 and a driving wheel 412. When the driving wheel 411 rotates, the round rod on the driving wheel 411 can fit into the through groove of the driving wheel 412 and drive the driving wheel 412 to rotate. The angle between the two adjacent through grooves on the transmission wheel 412 is 60 degrees. At the same time, since the rocker arm 42 is fixed on the transmission wheel 412, the center of gravity of the transmission wheel 412 sinks. Under the action of gravity, the transmission wheel 412 is driving Driven by the wheel 411, the wheel 411 does not rotate a full circle, but only rotates 60 degrees and then returns to the original position. The above-mentioned movement is repeated as the driving wheel 411 rotates, so that the tray 4 can swing regularly.

The tongue-shaped plate 21 in the upper opening of the small carrying box 2 can make the sample reagent bottle be placed obliquely, so that the liquid column in the sample reagent bottle is inclined, and the contact area between the liquid column and the constant temperature water flow in the small carrying box 2 is increased, and the result is achieved. Better constant temperature effect.

The rubber ring 22 in the upper opening of the small carrying box 2, on the one hand, can fix the sample reagent bottle to prevent it from moving at will; out of the box.

The thermal insulation layer 11 on the inner wall of the casing 1 can effectively prevent the external temperature change from affecting the internal environment of the casing 1 and thus change the constant temperature environment.

Both the handle 12 and the universal wheel 13 installed on the casing 1 are convenient for the operator to move and carry the device.

The utility model has the advantages of good constant temperature effect, tight protection of the sample reagent bottles, and the ability to carry multiple sample reagent bottles, which solves the problem that the existing bone marrow pathological samples cannot guarantee a constant temperature environment during the transportation process, and at the same time, it is inconvenient for human hands to carry a large number of reagent bottles The common reagent bottle rack cannot avoid the risk of breaking.

The above descriptions are merely embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
