The box comprises a box body and a sealing device, wherein a temperature control device is fixedly installed on the left side of the box body, a button is fixedly installed on the left side of the temperature control device, and the button is electrically connected to the temperature control device. A replacement hole is opened on the front side of the box body, a replacement plate is slidably installed on the front side of the box body, and a sealing plate is slidably penetrated on the right side of the box body, wherein the sealing device comprises a limiting hole, a limiting rod, a limiting spring, a U-shaped rod, a T-shaped plate, a stabilizing plate and a mesh frame. After an experimental container containing azacitidine is placed in the box body, the sealing plate is manually pulled to move to the left to reset and restore the sealing of the box body.

Description

Technical Field

[0001] The invention relates to the technical field of experimental equipment, in particular to an experimental box for raw material medicine azacitidine. Background Art

[0002] The experimental box for the raw material azacitidine usually consists of a box body, supporting equipment, temperature control equipment and protective equipment.

[0003] The patent with the patent announcement number CN220091456U relates to a low-temperature test box, including a test box body, buffer mechanisms are symmetrically arranged on both sides of the test box body, a placement frame is movably arranged in the test box body, movable connection blocks are fixedly installed on both sides of the bottom of the placement frame, a lifting mechanism is arranged between the placement frame and the bottom of the test box body, an air conditioner is fixedly installed on the outer wall of the test box body, an air outlet pipe is fixedly installed at the bottom of the test box body, the air conditioner and the air outlet pipe are connected through a connecting pipe, and a plurality of air outlet holes are opened on the air outlet pipe. The patent sets a lifting mechanism to make the placement frame move up and down, avoiding the need for workers to bend down one by one to operate when taking and placing test pieces, which increases the workload of workers and increases the labor intensity of workers. By setting a buffer mechanism, it plays a buffering role when the placement frame moves up and down, avoiding the increased impact force on the device when taking and placing concrete test pieces.

[0004] In the above patent, a buffer mechanism is provided to play a buffering role when the mounting frame moves up and down, thereby avoiding a large impact force on the device when the concrete specimen is taken and placed. However, it is difficult to prevent the sealing plate from loosening due to human error. Azacitidine is particularly sensitive to moisture. If azacitidine is exposed to a humid environment, the hydrolysis reaction of the drug will be accelerated, reducing its efficacy and stability. When the sealing plate is loosened due to human error, the humid air from the outside will more easily enter the interior of the box, causing the humidity inside the box to increase, thereby affecting the quality of the drug.

[0013] The present invention provides an experimental box for the raw material drug azacitidine. It has the following beneficial effects:

[0014] (1) This patent, by manually pulling the T-shaped plate toward the stabilizing plate, the T-shaped plate moves toward the stabilizing plate to break away from the contact with the bottom of the limit rod and release the limit on the limit rod. The loosening of the sealing plate will cause moisture in the air to enter the box, thereby accelerating the degradation of azacitidine. The anti-mistouch restriction of the T-shaped plate can ensure that the sealing plate is always tightly closed, thereby ensuring the stability of azacitidine. The sealing plate is moved to the left to restore the sealing of the box. The sealing plate and the rubber strip ensure the sealing of the box, thereby extending the shelf life of azacitidine and ensuring the optimal therapeutic effect of azacitidine during treatment.

[0015] (2) This patent, by moving the second rack toward the T-shaped plate, drives the curved plate to move. The movement of the curved plate cooperates with the arc plate to assist in fixing the experimental container containing azacitidine. During the transportation or storage of azacitidine, any slight tilt or movement of the box will cause leakage or contamination of azacitidine. The auxiliary fixing design of the arc plate ensures that the experimental container is always in the predetermined position, effectively avoiding the risk of leakage and contamination. The activated carbon particles inside the mesh frame are stirred by rotating the stirring rod. Stirring the activated carbon particles by the stirring rod can avoid the accumulation or agglomeration of the activated carbon particles, so that the activated carbon particles can continuously and effectively adsorb moisture, further ensuring that azacitidine can be stored within the specified humidity range.

[0016] (3) In this patent, the linkage plate is squeezed by the liquid inside the L-shaped tube and moves upward. The upward movement of the linkage plate drives the L-shaped rod to move upward. The L-shaped rod moves upward to break away from the contact with the protective groove and release the limit on the button. After the limit on the button is released, the temperature control device can be adjusted by pressing the button. Frequent adjustment of the temperature control device will cause adverse temperature fluctuations, thereby affecting the stability and activity of azacitidine. By making it impossible to adjust the temperature control device through the button when the box is sealed, the stability and activity of azacitidine can be ensured, thereby improving the storage stability of azacitidine.

[0034] The limiting device includes an L-shaped tube 141, a monitoring plate 142, a monitoring rod 143, a linkage plate 144 and an L-shaped rod 145. The L-shaped tube 141 is fixedly installed on the left side of the box body 1, the monitoring plate 142 is slidably installed on the inner wall of the L-shaped tube 141, the monitoring rod 143 is fixedly installed on the right side of the monitoring plate 142, and a No. 1 spring is arranged between the L-shaped tube 141 and the monitoring plate 142.

When the T-shaped plate 9 moves toward the direction close to the stabilizing plate 10, the T-shaped plate 9 moves toward the direction close to the stabilizing plate 10 and breaks away from the contact with the arc panel 134. The arc panel 134 breaks away from the contact with the stabilizing plate 10, causing the rotating rod 131 to rotate clockwise under the elastic force of the clockwork spring.

The second rack 135 moves away from the T-shaped plate 9 and drives the curved panel 136 to move and reset to break away from the contact with the experimental container. At the same time, the rotation of the rotating rod 131 drives the stirring rod 137 to rotate. The stirring rod 137 rotates to stir the activated carbon particles inside the mesh frame 12. The stirring of the stirring rod 137 enhances the absorption effect of the activated carbon particles on the moisture inside the box 1.

[0037] The second rack 135 moves in the direction away from the T-shaped plate 9, driving the curved plate 136 to move. The curved plate 136 moves in the direction away from the T-shaped plate 9 and contacts and squeezes the monitoring rod 143. The monitoring rod 143 is squeezed by the curved plate 136 and moves in the direction away from the arc plate 134.

The first spring is pulled by the monitoring plate 142 to produce deformation and accumulate force. At the same time, the monitoring plate 142 moves to the liquid inside the L-shaped tube 141. The body is squeezed, and the liquid inside the L-shaped tube 141 is squeezed by the monitoring plate 142 and moves toward the direction close to the linkage plate 144. The liquid inside the L-shaped tube 141 moves toward the direction close to the linkage plate 144 to squeeze the linkage plate 144. The linkage plate 144 is squeezed by the liquid inside the L-shaped tube 141 and moves upward. The upward movement of the linkage plate 144 drives the L-shaped rod 145 to move upward. The L-shaped rod 145 moves upward to break away from the contact with the protective groove and releases the limit on the button 146. After the limit of the button 146 is released, the temperature control device 2 can be adjusted by pressing the button 146.
