[0002] With the advancement of medical technology and people's growing demand for health, blood testing, as one of the important means of diagnosing diseases, plays an extremely important role in clinical medicine. The quality of blood samples directly affects the accuracy of test results, so it is very important to ensure the stability of blood samples during transportation after collection.

[0003] During the transportation of blood samples, the sample rack is prone to violent shaking due to road bumps or improper handling. This shaking may not only cause collisions between sample bottles, but may also cause blood components (such as red blood cells, white blood cells, platelets, etc.) to deform or be damaged by mechanical stress, thereby affecting the accuracy of subsequent test results. Even if the sample rack is designed to have a certain degree of stability, since the sample bottle is usually smaller than the diameter of the slot in which it is placed, the sample bottle may still collide with the inner wall of the slot during transportation. This collision will also cause changes in the components of the blood sample, affecting the test results. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] A sample refrigeration storage box for blood testing, such as Figure 1-8 As shown, the refrigerator 100 includes a moving plate 110, a support frame 120, a sample holder 130, a placement slot 140, a sample bottle 160, a stopper 150, a buffer mechanism 200, a speed reduction mechanism 300 and a support mechanism 400; the moving plate 110 is slidably connected to the inner wall of the refrigerator 100; the support frame 120 is fixedly connected to the inner wall of the refrigerator 100, and the support frame 120 is located above the moving plate 110; the sample holder 130 passes through the support frame 120 and is placed on the moving plate 110; multiple placement slots 140 are all opened on the sample rack 130; the sample bottle 160 is prevented from being placed in the placement slot 140; two limit members 150 are symmetrically arranged on both sides of the sample rack 130; multiple buffer mechanisms 200 are arranged between the bottom wall of the refrigerator 100 and the movable plate 110; the number of the deceleration mechanism 300 is consistent with the number of the buffer mechanism 200, and the deceleration mechanism 300 is arranged in the buffer mechanism 200; multiple support mechanisms 400 are all arranged in the placement slot 140.

[0021] By arranging a movable plate 110 in the refrigerator 100, and a support frame 120 above the movable plate 110, the sample rack 131 of the blood sample can be placed on the movable plate 110 through the support frame 120. By arranging a buffer mechanism 200 below the movable plate 110, it is prevented that the refrigerator 100 is violently shaken during the movement, causing the blood sample to also shake, thereby causing a certain stimulation to the blood vessel wall, causing partial coagulation of the blood, resulting in a decrease in the number of red blood cells, white blood cells, platelets, etc. in the blood, thereby affecting the accuracy of the inspection result; at the same time, by arranging a deceleration mechanism 300 in the buffer mechanism 200, the sample rack 130 is prevented from being separated from the limit of the limit member 150. After the control, the sample rack 130 can be slowly raised. On the one hand, it can prevent the sample rack 130 from quickly bouncing upward after being released from the restriction, thereby affecting the blood sample. On the other hand, the upward rise of the sample rack 130 facilitates the removal of the sample rack 130 and facilitates the next operation of the blood sample. Because the diameter of the placement groove 140 is generally larger than the diameter of the blood sample bottle 160, even if the entire sample rack 131 is shaken less, the sample bottle 160 is easy to collide with the inner wall of the placement groove 140. Therefore, a supporting mechanism 400 is provided on the inner wall of each placement groove 140 to prevent the sample bottle 160 from colliding with the inner wall of the placement groove 140, thereby further preventing the blood sample from shaking.

[0022] In an embodiment of the present invention, Figure 1-8 As shown, a buffer pad is provided on the moving plate 110 .

[0023] By providing a buffer pad on the movable plate 110 , a certain buffering effect can be played on the sample holder 130 .

[0024] In an embodiment of the present invention, Figure 1-8 As shown, the sample rack 130 includes: a sample rack 131, a side 132 and an embedding groove 133, which passes through the support frame 120 and is placed on the movable plate 110; the two side edges 132 are symmetrically fixedly connected to the sample rack 131, and the side edges 132 are arranged above the support frame 120; the two embedding grooves 133 are respectively opened on the two side edges 132.

[0025] By providing side edges 132 on both sides of the sample rack 131 , the two side edges 132 can be placed on the support frame 120 and aligned and fixed by the stopper 150 , thereby preventing the sample rack 131 from shaking up and down in the refrigerator 100 .

[0026] In an embodiment of the present invention, Figure 1-8As shown, the limiting member 150 includes: a limiting hole 151, a moving column 152, a limiting plate 153, a first spring 154 and a limiting block 155; the limiting hole 151 is opened on the support frame 120; the moving column 152 is slidingly connected to the limiting hole 151; the limiting plate 153 is fixedly connected to the moving column 152, and the limiting plate 153 is slidingly connected to the inner wall of the limiting hole 151; the first spring 154 is sleeved on the moving column 152, and one end of the first spring 154 abuts against the inner wall of the limiting hole 151, and the other end of the first spring 154 abuts against the limiting plate 153; the limiting block 155 is fixedly connected to the side of the moving column 152 away from the limiting hole 151, and the limiting block 155 is embedded in the embedding groove 133.

[0027] When the sample rack 131 is placed in the support frame 120, the limit blocks 155 on both sides are pulled and rotated. At this time, the first spring 154 is squeezed to rotate the extended ends of the limit blocks 155 on both sides to one side of the sample rack 131 and align them with the embedding groove 133. Then, the limit blocks 155 are released to allow the limit blocks 155 to enter the embedding groove 133 to prevent the sample rack 131 from shaking up and down in the refrigerator 100.

[0028] In an embodiment of the present invention, Figure 1-8 As shown, the buffer mechanism 200 includes: a cavity cylinder 210, a sliding column 220, a sliding block 230 and a second spring 240; the cavity cylinder 210 is fixedly connected to the bottom wall of the refrigerator 100; one end of the sliding column 220 is fixedly connected to the movable plate 110, and the other end of the sliding column 220 is slidably connected to the cavity cylinder 210; the sliding block 230 is fixedly connected to the sliding column 220, and the sliding block 230 is slidably connected to the inner wall of the cavity cylinder 210; the second spring 240 is sleeved on the sliding column 220, and one end of the second spring 240 is in contact with the movable plate 110, and the other end of the second spring 240 is in contact with the cavity cylinder 210.

[0029] When the sample rack 131 is placed on the movable plate 110, the movable plate 110 moves downward, pushing the sliding column 220 and the sliding block 230 fixedly connected thereto to move toward the bottom of the cavity tube 210, thereby squeezing the second spring 240. Under the elastic force of the second spring 240, when the sample rack 131 shakes, the second spring 240 absorbs a certain amount of kinetic energy, so that the sample rack 131 is more stable on the movable plate 110, thereby preventing the refrigerator 100 from shaking violently during the movement, causing the blood sample to shake, and then causing the blood vessel wall to be stimulated to a certain extent, causing the blood to partially coagulate, resulting in a decrease in the number of red blood cells, white blood cells, platelets, etc. in the blood, thereby affecting the accuracy of the inspection result.

[0030] In an embodiment of the present invention, Figure 1-8As shown, the deceleration mechanism 300 includes: a through hole 310, a one-way valve 320 and a rubber ring; multiple through holes 310 are all opened on the sliding block 230; the number of one-way valves 320 is less than the number of through holes 310, and the one-way valves 320 are arranged in the through holes 310; the rubber ring is set on the sliding block 230.

[0031] When the sliding column 220 pushes the sliding block 230 to move toward the bottom of the cavity tube 210, high-pressure nitrogen is filled into the sliding column 220. Because the sliding block 230 is attached with a rubber ring, the gas passes through the through hole 310 and the one-way valve 320 (the one-way valve 320 can only allow the gas to flow from bottom to top, not from top to bottom) and enters the upper part of the cavity tube 210. When the sample rack 131 is free from the restrictions of the two limit blocks 155, the second spring 240 pushes the moving plate 110 to move upward, thereby driving the sliding column 220 to move upward as well. The movement drives the sliding block 230 to move upward, and then the gas flows downward from the through hole 310. Since a one-way valve 320 is provided in some of the through holes 310, the gas can only flow downward from the through holes 310 without the one-way valve 320. Therefore, the airflow slows down, thereby causing the upward speed of the moving plate 110 to slow down, so as to avoid the sample rack 131 from quickly bouncing upward after being released from the restriction, thereby affecting the blood sample. At the same time, the sample rack 131 rises upward, which is convenient for taking out the sample rack 131 and facilitating the next operation of the blood sample.

[0032] In an embodiment of the present invention, Figure 1-8 As shown, the support mechanism 400 includes: a spring sheet 410, a third spring 420, a notch 430, a fixing rod 440 and a rolling column 450; the spring sheet 410 is arranged at an angle, and one end of the spring sheet 410 is fixedly connected to the inner wall of the placement groove 140; one end of the third spring 420 is fixedly connected to the spring sheet 410, and the other end of the third spring 420 is fixedly connected to the inner wall of the placement groove 140; the notch 430 is opened at the spring sheet 410 away from the inner wall of the placement groove 140; the fixing rod 440 is fixedly connected to the notch 430; and the rolling column 450 is rotatably connected to the fixing rod 440.

[0033] When the sample bottle 160 filled with blood is inserted into the placement groove 140, the sample bottle 160 contacts the rolling column 450. By providing a plurality of supporting mechanisms 400 on the peripheral side of the placement groove 140, the peripheral side of the sample bottle 160 can be supported, and the rolling column 450 is rotatably connected to the fixing rod 440, so that when the sample bottle 160 is inserted downward, the rolling column 450 will rotate, so that the sample bottle 160 can be smoothly inserted into the placement groove 140. At the same time, the rolling column 450 is supported by the spring sheet 410, and a third spring 420 is provided between the spring sheet 410 and the inner wall of the placement groove 140, so that the sample bottle 160 can be supported, thereby avoiding collision between the sample bottle 160 and the inner wall of the placement groove 140, and further avoiding shaking of the blood sample.

[0034] In an embodiment of the present invention, Figure 1-8 As shown, the rolling post 450 is an arc-shaped post.

[0035] Because the sample bottle 160 is usually round, the rolling column 450 is designed as an arc column so that the rolling column 450 can better fit the sample bottle 160. At the same time, a rubber pad can be pasted on the outside of the rolling column 450 to increase the friction between the sample bottle 160 and the rolling column 450, thereby providing good support for the sample bottle 160.

[0036] In an embodiment of the present invention, Figure 1-8 As shown, it also includes: a box cover 170, a handle 180 and a lock 190. The box cover 170 covers the top of the refrigerator 100; the handle 180 is arranged on the box cover 170; and the lock 190 is fixedly connected to the refrigerator 100 and the box cover 170.

[0037] The handle 180 is provided to facilitate carrying the refrigerator 100 ; the lock 190 is provided on the refrigerator 100 and the cover 170 , to facilitate fixing the cover 170 to the refrigerator 100 .

[0038] Implementation process: When in use, the sample bottle 160 with the blood sample is placed in the placement slot 140 on the sample rack 131, and the sample bottle 160 is supported by the multiple supporting mechanisms 400 in each placement slot 140 to prevent it from shaking with the inner wall of the placement slot 140 and affecting the blood sample. After the blood sample is collected, the sample rack 131 with the blood sample bottle 160 is placed on the moving plate 110 in the refrigerator 100, and the moving plate 110 moves downward to push the sliding column 220 and the sliding column 220 fixedly connected to it. The sliding block 230 moves toward the bottom of the cavity tube 210, thereby squeezing the second spring 240. Under the elastic force of the second spring 240, when the sample rack 131 shakes, the second spring 240 absorbs a certain amount of kinetic energy, so that the sample rack 131 is more stable on the moving plate 110, thereby preventing the refrigerator 100 from shaking violently during the movement, causing the blood sample to shake, and then causing the blood vessel wall to be stimulated to a certain extent, causing the blood to partially coagulate, resulting in a decrease in the number of red blood cells, white blood cells, platelets, etc. in the blood. The sample rack 131 is reduced, thereby affecting the accuracy of the inspection result. At the same time, the upper part of the sample rack 131 is limited by the limit pieces 150 on both sides to prevent the sample rack 131 from shaking up and down with a large amplitude, which may affect the blood sample. When the sample rack 131 needs to be taken out, the limit blocks 155 on both sides are pulled and rotated to the side away from the side 132. When the sample rack 131 is free from the limit of the two limit blocks 155, the second spring 240 pushes the moving plate 110 to move upward, thereby driving the sliding column 220 to move upward as well. The sliding block 230 moves upward, thereby driving the sliding block 230 to move upward, and then the gas flows downward from the through hole 310. Since a one-way valve 320 is provided in some of the through holes 310, the gas can only flow downward from the through holes 310 without the one-way valve 320. Therefore, the airflow slows down, thereby causing the upward speed of the moving plate 110 to slow down, so as to avoid the sample rack 131 from quickly bouncing upward after being released from the restriction, thereby affecting the blood sample. At the same time, the sample rack 131 rises upward, which is convenient for taking out the sample rack 131 and facilitating the next operation of the blood sample.

[0039] It should be noted that the specific models and specifications of the first spring 154, the second spring 240, the one-way valve 320 and the third spring 420 need to be selected and determined according to the actual specifications of the device, so they are not described in detail.

[0040] The above are only preferred 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 variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
