Description

Technical Field

[0001] The utility model relates to the technical field of ferritin detection kits, in particular to a ferritin detection kit. Background Art

[0002] The ferritin test kit is a tool used to measure the ferritin level in the blood or body fluids. The concentration of ferritin needs to be strictly controlled. Iron deficiency in the body can cause certain diseases, but iron cannot be excessive. A large amount of iron accumulates in important organs such as the liver, causing liver damage. Therefore, the ferritin content needs to be tested. Usually, a test kit is used for testing. The test kits used in existing laboratories can usually be reused.

[0003] The Chinese patent "A Ferritin Detection Kit with Distinguishing Reagent Tubes" authorization announcement number "CN218229905U" is connected to the support plate shaft by a connecting shaft. The connecting shaft is shaken by a hand crank and limited by a limit rod, so that the connecting shaft drives the detection reagent tube inside the support plate to swing back and forth, thereby accelerating the mixing speed of the reagent inside the detection reagent tube.

[0004] In the above scheme, the support plate is used to drive the test tube to swing to improve the mixing efficiency of the reagents. However, when the test tube is inserted into the support plate, the test tube is not fixed. Under the action of gravity, the bottom end of the test tube will contact the partition mesh plate. When the test tube rotates, a large friction force will be generated between the bottom end of the test tube and the partition mesh plate, which may easily cause damage to the test tube and leakage of the reagent, thereby affecting the accuracy of the experimental results.

[0005] Therefore, a ferritin detection kit is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a ferritin detection kit in order to solve the above-mentioned problem. The utility model improves the problem that when the test tube is inserted into the support plate, the test tube is not fixed. Under the action of gravity, the bottom end of the test tube will contact the partition mesh plate. When the test tube rotates, a large friction force will be generated between the bottom end of the test tube and the partition mesh plate, which can easily cause damage to the test tube and leakage of reagents, thereby affecting the accuracy of the experimental results.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a ferritin detection kit, comprising: a detection box, the inner wall of the detection box is rotatably connected with a placement plate, the top of the placement plate is provided with circular holes distributed in equal rows, and a fixing mechanism is arranged inside the circular holes; wherein the fixing mechanism comprises a support plate slidably connected to the lower end of the inner wall of the detection box, the inner wall of the circular hole is provided with an annular groove, the inner wall of the annular groove is provided with an annular airbag, the bottom end of the placement plate is fixedly connected with air storage rings distributed in equal rows, the position of the air storage rings corresponds to the position of the circular holes one by one, the inner wall of the air storage ring is slidably connected with an extrusion plate, a connecting pipe is arranged between the air storage ring and the annular airbag, and a driving component is arranged at the bottom end of the air storage ring.

[0008] Preferably, the driving assembly includes a moving plate slidably connected to the inner wall of the detection box, the inner wall of the moving plate is fixedly connected with annular plates distributed in equal rows, the position of the annular plates corresponds to the position of the gas storage ring, the bottom end of the extrusion plate is fixedly connected with a push rod, the bottom end of the push rod penetrates the gas storage ring and is fixedly connected to the top of the annular plate, one side of the detection box is fixedly connected with two fixed blocks, a threaded rod is rotatably connected between the opposite sides of the two fixed blocks, the surface of the threaded rod is threadedly connected with a round rod, one end of the round rod penetrates the detection box and is fixedly connected to one side of the moving plate. Under the action of the threaded rod and the round rod, the push rod pushes the extrusion plate to move upward to squeeze the gas in the gas storage ring, which is conducive to the gas in the gas storage ring entering the annular airbag so that the annular airbag expands and contacts the surface of the test tube and wraps the test tube to fix it, thereby ensuring the stability of the test tube when rotating.

[0009] Preferably, one side of the support plate passes through the test box and is fixedly connected with a pull rope, the other end of the pull rope is fixedly connected with a ring, and the lower end of one side of the test box is fixedly connected with a hook. When the test tube is placed, under the action of the pull rope, the ring and the hook, it is convenient to pull and fix the support plate. After the test tube is fixed, the contact between the ring and the hook is released, which is convenient for the support plate to automatically move downward and release the contact with the test tube, avoiding the test tube from contacting the bottom of the test tube and the support plate when the test tube reciprocates, thereby reducing the friction of the test tube when it reciprocates.

[0010] Preferably, one end of the rotation axis of the placement plate passes through the detection box and is fixedly connected to a handle, and the lower end of the surface of the rotation axis of the placement plate is fixedly connected to a limit rod. When the device is in the initial state, the round rod and the limit rod are used to limit the rotation axis of the placement plate, ensuring that the placement plate is in a stable state when placing the test tube, thereby improving the stability of the test tube when being placed.

[0011] Preferably, the lower end of the surface of the limiting rod is bent into an arc shape.

[0012] Preferably, a mounting plate is fixedly connected to the upper surface of the rotation axis of the placement plate, two limit blocks are fixedly connected to one side of the detection box, and the mounting plate is arranged between the two limit blocks. Under the action of the two symmetrically arranged limit blocks, the rotation angle of the placement plate is limited, which is conducive to better observation of the rotation angle of the placement plate.

[0013] Preferably, the angle between the two limit blocks is less than 90 degrees, so as to avoid the placement plate from rotating at too large an angle and ensure the stability of the test tube during the reciprocating rotation.

[0014] Preferably, the bottom end of the threaded rod passes through a fixed block and is fixedly connected with a knob, which is conducive to making it more convenient for the staff to rotate.

[0015] The beneficial effects of the utility model are:

[0016] 1. The setting of the fixing mechanism: when the test tube is inserted through the round hole, the support plate is used to initially support the test tube, and the push rod pushes the extrusion plate upward to squeeze the gas in the gas storage ring under the action of the threaded rod and the round rod, which is conducive to the gas in the gas storage ring entering the annular air bag so that the annular air bag expands and contacts the surface of the test tube and fixes the test tube in a wrapped manner, thereby ensuring the stability of the test tube during rotation. At the same time, after the test tube is fixed, the support plate moves downward and releases the contact with the test tube. Under the action of the fixing mechanism, it is conducive to making the bottom of the test tube in a suspended state, thereby avoiding the damage caused by the large friction force at the bottom of the test tube during the rotation process, improving the safety of the test tube during the reciprocating rotation process, and thus ensuring the accuracy of the experiment;

[0017] 2. When placing the test tube, the pull rope, the ring and the hook are used to pull and fix the support plate. After the test tube is fixed, the contact between the ring and the hook is released, which is conducive to the support plate automatically moving downward and releasing the contact with the test tube, avoiding the contact between the bottom of the test tube and the support plate when the test tube reciprocates, thereby reducing the friction of the test tube when it reciprocates;

[0018] 3. When the device is in the initial state, the round rod and the limit rod are used to limit the rotation axis of the placement plate, ensuring that the placement plate is in a stable state when placing the test tube, thereby improving the stability of the test tube when being placed.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] When implementing: Figure 1-5 As shown, a ferritin detection kit comprises: a detection box 1, the inner wall of the detection box 1 is rotatably connected with a placement plate 2, the top of the placement plate 2 is provided with circular holes 3 distributed in equal rows, and a fixing mechanism 4 is arranged inside the circular holes 3; wherein the fixing mechanism 4 comprises a support plate 401 slidably connected to the lower end of the inner wall of the detection box 1, the inner wall of the circular hole 3 is provided with an annular groove 402, the inner wall of the annular groove 402 is provided with an annular airbag 403, the bottom end of the placement plate 2 is fixedly connected with an air storage ring 404 distributed in equal rows, the position of the air storage ring 404 corresponds to the position of the circular hole 3 one by one, the inner wall of the air storage ring 404 is slidably connected with an extrusion plate 405, a connecting pipe 406 is arranged between the air storage ring 404 and the annular airbag 403, and a driving component 407 is arranged at the bottom end of the air storage ring 404.

[0027] The detection box 1 has a cover body and a box body. The inner bottom wall of the detection box 1 is provided with an ice pack drawer. Similar to the original scheme, when ferritin needs to be tested, the reagent to be tested is placed in a test tube, and the test tube is inserted into the circular hole 3. At this time, the support plate 401 supports the bottom of the test tube. After placement is completed, the fixing mechanism 4 is driven to fix the test tube.

[0028] like Figure 2 , Figure 3and Figure 4 As shown, the driving assembly 407 includes a moving plate 4074 slidably connected to the inner wall of the detection box 1, the inner wall of the moving plate 4074 is fixedly connected with annular plates 4075 distributed in equal rows, the positions of the annular plates 4075 correspond one to one with the positions of the air storage rings 404, the bottom end of the extrusion plate 405 is fixedly connected with a push rod 4076, the bottom end of the push rod 4076 passes through the air storage ring 404 and is fixedly connected to the top of the annular plate 4075, one side of the detection box 1 is fixedly connected with two fixed blocks 4071, the opposite sides of the two fixed blocks 4071 are rotatably connected with a threaded rod 4072, the surface of the threaded rod 4072 is threadedly connected with a round rod 4073, one end of the round rod 4073 passes through the detection box 1 and is fixedly connected to one side of the moving plate 4074.

[0029] Two push rods 4076 are fixedly connected to the bottom end of each extrusion plate 405 . Two push rods 4076 form a group. Both push rods 4076 are fixedly connected to the top end of the annular plate 4075 corresponding to the bottom end of the gas storage ring 404 .

[0030] When the test tube is inserted through the circular hole 3, the bottom end of the test tube will pass through the gas storage ring 404 and the annular plate 4075 in sequence. After the test tube is placed in, the staff rotates the threaded rod 4072 to drive the round rod 4073 to move upward, thereby driving the movable plate 4074 to move upward synchronously. When the movable plate 4074 moves upward, under the action of the annular plate 4075, it will push multiple groups of push rods 4076 to move upward synchronously. When the push rods 4076 move upward, they will push the corresponding extrusion plates 405 to move upward and squeeze the gas in the gas storage ring 404. After the gas is squeezed, it enters the annular airbag 403 through the connecting tube 406, causing the annular airbag 403 to expand and contact the surface of the test tube and wrap the test tube for fixation. After the fixation is completed, the rotation of the threaded rod 4072 is stopped.

[0031] One side of the support plate 401 passes through the detection box 1 and is fixedly connected with a pull rope 4011 , the other end of the pull rope 4011 is fixedly connected with a ring 4012 , and the lower end of one side of the detection box 1 is fixedly connected with a hook 4013 .

[0032] When placing the test tube, the ring 4012 is hung on the hook 4013, and the support plate 401 is pulled and limited by the pull rope 4011, so that the support plate 401 supports the placed test tube. When the test tube is fixed, the ring 4012 is removed from the hook 4013 to release the contact between the ring 4012 and the hook 4013. At this time, the pull rope 4011 and the support plate 401 lose tension and move downward under the action of the support plate 401's own gravity. A moving groove matching the movement of the support plate 401 is opened in the detection box 1. When the support plate 401 moves downward, it is released from the test tube.

[0033] like Figure 3As shown, one end of the rotating shaft of the placing plate 2 passes through the detection box 1 and is fixedly connected with a turning handle, and the lower end of the surface of the rotating shaft of the placing plate 2 is fixedly connected with a limiting rod 203. The lower end of the surface of the limiting rod 203 is curved in an arc shape.

[0034] When the device is in the initial state, the round rod 4073 is located in the recess of the limiting rod 203, and the lower end of the surface of the round rod 4073 fits with the surface of the recess of the limiting rod 203, thereby limiting the limiting rod 203 and thus limiting the rotation axis of the placement plate 2. When the round rod 4073 is driven to move upward to fix the test tube, the round rod 4073 will be disengaged from the recess of the limiting rod 203, and at this time, the rotation axis of the placement plate 2 can rotate normally.

[0035] like Figure 2 As shown, the upper surface of the rotating shaft of the placing plate 2 is fixedly connected with a mounting plate 201, and one side of the detection box 1 is fixedly connected with two limit blocks 202, and the mounting plate 201 is arranged between the two limit blocks 202. The angle between the two limit blocks 202 is less than ninety degrees.

[0036] After the test tube is fixed, the handle is turned to drive the rotating shaft of the placement plate 2 to rotate, so that the placement plate 2 drives the test tube to rotate. When the rotating shaft of the placement plate 2 rotates, it drives the mounting plate 201 to rotate synchronously. The two limit blocks 202 are symmetrical with the center of the mounting plate 201. Under the action of the mounting plate 201 and the limit blocks 202, the rotation angle of the placement plate 2 is less than 90 degrees.

[0037] like Figure 3 As shown, the bottom end of the threaded rod 4072 passes through the fixing block 4071 and is fixedly connected with a knob. A groove begins to appear on the surface of the knob, and when the threaded rod 4072 needs to be turned, the knob can be turned.

[0038] When the utility model is in use and ferritin needs to be detected, the reagent to be detected is placed in the test tube, and the test tube is inserted into the circular hole 3. At this time, the support plate 401 supports the bottom of the test tube. After the test tube is placed, the staff rotates the threaded rod 4072 to drive the round rod 4073 to move upward, thereby driving the moving plate 4074 to move upward synchronously. Under the action of the annular plate 4075, multiple groups of push rods 4076 are pushed to move upward synchronously, and the corresponding extrusion plates 405 are pushed to move upward to squeeze the gas in the gas storage ring 404. The gas enters the annular airbag 403 through the connecting tube 406, so that the annular airbag 403 expands and contacts with the surface of the test tube and wraps and fixes the test tube. After the fixation is completed, the circular ring 4012 is removed from the hook 4013 to release the contact between the circular ring 4012 and the hook 4013. The support plate 401 moves downward under the action of its own gravity and releases the release from the test tube. At this time, the bottom of the test tube is in a suspended state.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
