More specifically, the reagent vessel can be snapped or hung within the placing through hole 211.

More specifically, the preset direction is a direction indicated by X as shown in fig. 1.

In the above reagent kit, since the reagent tube placing member 210 is provided with at least one placing through hole 211 for the reagent tube to pass through, and the placing through hole 211 penetrates through the upper and lower sides of the reagent tube placing member 210, the reagent tube to be detected can be stored in the placing through hole 211. And the reagent tube can be clamped or hung in the placing through hole 211, so that the reagent kit has the advantages of safety and reliability in the preservation process of the reagent tube.

In addition, since the outer protection member 100 is provided with the accommodating cavity 110 having the opening 111, the placing assembly 200 is movably disposed in the accommodating cavity 110, and the guide inclined wall 120 is disposed inside the accommodating cavity 110, when a reagent tube stored in the placing through hole 211 needs to be tested, the reagent tube placing member 210 in the accommodating cavity 110 can be dragged to move in the accommodating cavity 110 in a direction indicated by X shown in fig. 1. In the moving process, since the guide inclined wall 120 can give an upward pushing force to the reagent tube, the reagent tube can be pushed by the guide inclined wall 120 and move toward the outside of the opening 111, so that the reagent tube in the placing through hole 211 is pushed out from the placing through hole 211. After the reagent tube is pushed out of the placing through hole 211 by the guide inclined wall 120, the reagent tube can be easily taken out from the reagent cartridge.

As shown in fig. 2, in one embodiment, the guide inclined wall 120 is disposed on the bottom wall of the accommodating chamber 110, and the height of the guide inclined wall 120 is set from low to high along a preset direction.

In this manner, the first and

second slide assemblies

300 and 400 can suspend the reagent tube placement member 210 within the accommodation chamber 110 to facilitate storage of reagent tubes within the reagent tube placement member 210. When the reagent tube needs to be taken out from the reagent tube placing part 210, the reagent tube placing part 210 can be driven to slide along the preset direction only by sliding the first sliding assembly 300 in the first sliding groove 112 along the preset direction and sliding the second sliding assembly 400 in the second sliding groove 113 along the preset direction, and then the reagent tube can be pushed by the guide inclined wall 120 and moves towards the outer side of the opening 111, so that the reagent tube can be conveniently taken out from the reagent tube placing part 210.

When the reagent tube accommodating member 210 from which the reagent tube has been taken out needs to be restored, the reagent tube accommodating member 210 can be driven to slide along the reverse direction of the preset direction only by sliding the first sliding member 300 along the reverse direction of the preset direction in the first sliding groove 112 and sliding the second sliding member 400 along the reverse direction of the preset direction in the second sliding groove 113, so that the purpose of restoring the reagent tube accommodating member 210 from which the reagent tube has been taken out is achieved.

the second sliding assembly 400 includes a second fixed member 410 and a second movable member 420, the second fixed member 410 and the second movable member 420 are arranged in parallel and at an interval along a predetermined direction, one end of the second fixed member 410 is fixedly connected to the outer sidewall of the reagent tube placing member 210, one end of the second movable member 420 is movably connected to the outer sidewall of the reagent tube placing member 210, both the second fixed member 410 and the second movable member 420 are slidably disposed in the second sliding groove 113, and the second movable member 420 can be operatively retracted into the second sliding groove 113.

Specifically, one end of the first movable member 320, which is far away from the reagent tube placing member 210, protrudes out of the first sliding groove 112, and one end of the second movable member 420, which is far away from the reagent tube placing member 210, protrudes out of the second sliding groove 113.

Because the first fixed member 310 and the first movable member 320 are slidably disposed in the first sliding groove 112, and the second fixed member 410 and the second movable member 420 are slidably disposed in the second sliding groove 113, the reagent tube placing member 210 can horizontally move along a predetermined direction, thereby ensuring the stability and safety of the reagent tube during the movement. And because the end of the first movable member 320 far away from the reagent tube placing member 210 protrudes out of the first sliding groove 112, and the end of the second movable member 420 far away from the reagent tube placing member 210 protrudes out of the second sliding groove 113, the stability of the first sliding member 300 sliding in the first sliding groove 112 and the stability of the second sliding member 400 sliding in the second sliding groove 113 can be further ensured, so that the stability and the safety of the reagent tube in the moving process can be further ensured. And because one end of the first fixing member 310 is fixedly connected to the outer sidewall of the reagent tube holding member 210, and one end of the second fixing member 410 is fixedly connected to the outer sidewall of the reagent tube holding member 210, when a reagent tube needs to be taken out from the reagent tube holding member 210, the reagent tube holding member 210 can be driven to move along the preset direction only by dragging the first fixing member 310 to slide along the preset direction in the first sliding groove 112, or dragging the second fixing member 410 to slide along the preset direction in the second sliding groove 113, so that the reagent tube can be pushed by the guide inclined wall 120 and move towards the outer side of the opening 111, thereby achieving the purpose of taking out the reagent tube from the reagent tube holding member 210.

In addition, since the first movable member 320 can be retracted into the first sliding groove 112 and the second movable member 420 can be retracted into the second sliding groove 113, the reagent kit can be conveniently packaged, and the first movable member 320 protruding from the first sliding groove 112 and the second movable member 420 protruding from the second sliding groove 113 can be prevented from affecting the packaging.

In another embodiment, the end of the first fixing member 310 away from the reagent tube placing member 210 protrudes from the first sliding groove 112, and the end of the second fixing member 410 away from the reagent tube placing member 210 protrudes from the second sliding groove 113.

In this way, it is possible to further facilitate the dragging of the first fixing member 310 to slide in the first sliding groove 112 and the dragging of the second fixing member 410 to slide in the second sliding groove 113, so that it is possible to more conveniently manipulate the movement of the reagent tube placing member 210 in the preset direction.

As shown in fig. 3, 4, 5 and 6, in one embodiment, a third sliding groove 212 is formed on a side wall of the reagent tube placing member 210, the first fixing member 310 is fixedly disposed in the third sliding groove 212, the first moving member 320 is slidably disposed in the third sliding groove 212, the first fixing member 310 is located behind the first moving member 320 along a predetermined direction, the first sliding assembly 300 further includes a first elastic member 330 disposed in the third sliding groove 212, one end of the first elastic member 330 is fixedly connected to the first moving member 320, and the other end of the first elastic member 330 is fixedly connected to one end of the third sliding groove 212 far away from the first fixing member 310;

When the reagent tube placing member 210 is released, the elastic potential energy of the second elastic member 430 can make the second elastic member 430 have a tendency to move in a direction opposite to the predetermined direction, so that the second elastic member 430 can drive the reagent tube placing member 210 to move in the direction opposite to the predetermined direction.

the third movable unit 421 has a second movable rod 4211, the fourth movable unit 422 has a second movable sleeve 4221, the second movable rod 4211 is movably inserted into the second movable sleeve 4221, the second elastic unit 423 is disposed in the second movable sleeve 4221, one end of the second elastic unit 423 is connected with the second movable sleeve 4221, and the other end of the second elastic unit 423 is connected with the second movable rod 4211.

Because the first movable unit 321 and the second movable unit 322 of the first movable member 320 are disposed along the width direction of the guiding inclined wall 120, the first movable unit 321 is located at the outer side of the second movable unit 322, and the first elastic unit 323 is located between the first movable unit 321 and the second movable unit 322, when the above-mentioned reagent kit is packaged, the first movable unit 321 is pushed to move towards the direction close to the second movable unit 322, and the first movable rod 3211 of the first movable unit 321 can move towards the end of the first movable sleeve 3221 close to the reagent tube placing member 210 in the first movable sleeve 3221 of the second movable unit 322, so that the first movable unit 321 can retract into the first sliding groove 112, and at this time, the first elastic unit 323 has elastic potential energy.

Meanwhile, since the third movable unit 421 and the fourth movable unit 422 of the second movable member 420 are disposed along the width direction of the guiding inclined wall 120, the third movable unit 421 is located outside the fourth movable unit 422, and the second elastic unit 423 is located between the third movable unit 421 and the fourth movable unit 422, when the above-mentioned reagent kit is packaged, the third movable unit 421 is pushed to move toward the direction close to the fourth movable unit 422, so that the second movable rod 4211 of the third movable unit 421 can move toward the end of the first movable sleeve 3221 close to the reagent tube placing member 210 in the first movable sleeve 3221 of the second movable unit 322, so that the third movable unit 421 can retract into the second sliding groove 113, and at this time, the second elastic unit 423 has elastic potential energy.

It is possible to avoid the influence of the movement of the first moving part 320 and the second moving part 420 on the packaging of the reagent cartridge.

In addition, when the package of the reagent kit is removed, since the first elastic unit 323 has elastic potential energy, the first elastic unit 323 can have a tendency to move in a direction away from the second movable unit 322, so as to drive the first movable unit 321 to move in a direction away from the second movable unit 322. Meanwhile, the second elastic unit 423 has elastic potential energy, so that the second elastic unit 423 has a tendency of moving in a direction away from the fourth movable unit 422, and thus the third movable unit 421 is driven to move in a direction away from the fourth movable unit 422. The first movable unit 321 and the third movable unit 421 can be in the working state at this time, and there is no need to use an external force or other devices to bring the first movable unit 321 and the third movable unit 421 into the working state, so the reagent kit has an advantage of being convenient to operate when in use.

And because the second movable unit 322 and the end of the first movable unit 321 close to the second movable unit 322 are both movably disposed in the third sliding groove 212, and the end of the fourth movable unit 422 and the end of the third movable unit 421 close to the fourth movable unit 422 are both movably disposed in the fourth sliding groove 213, when the first movable element 320 moves along the preset direction, the first movable element can be limited by the third sliding groove 212, and when the second movable element 420 moves along the preset direction, the second movable element can be limited by the fourth sliding groove 213, so as to enhance the stability of the reagent kit during movement. Moreover, since the third sliding groove 212 can prevent the first movable unit 321 from falling out of the third sliding groove 212 when the first movable unit 321 moves in a direction approaching or separating from the second movable unit 322, when the first elastic unit 323 drives the first movable unit 321 to move in a direction separating from the second movable unit 322, the first movable unit 321 will not be ejected out of the third sliding groove 212 due to the elastic potential energy of the first elastic unit 323. Similarly, since the fourth sliding groove 213 can prevent the third movable unit 421 from falling out of the fourth sliding groove 213 when the third movable unit 421 moves in a direction approaching or moving away from the fourth movable unit 422, when the second elastic unit 423 drives the third movable unit 421 to move in a direction moving away from the fourth movable unit 422, the third movable unit 421 will not be ejected out of the fourth sliding groove 213 due to the elastic potential energy of the second elastic unit 423.

As shown in fig. 2 and 8, in one embodiment, the reagent kit further includes a buffer assembly 500, the buffer assembly 500 is disposed in the accommodating chamber 110, and the buffer assembly 500 is located behind the reagent tube placing member 210 along a predetermined direction.

Thus, when the reagent tube placer 210 is driven by the elastic potential energy of the first elastic member 330 and the second elastic member 430 to move in the opposite direction of the predetermined direction to return to the initial position before dragging, the buffering assembly 500 can provide a buffering effect for the reagent tube placer 210, so that the reagent tube placer 210 does not collide with the outer protection member 100, thereby ensuring the safety of the reagent tubes stored in the reagent tube placer 210.

As shown in fig. 2 and 8, the outer protection member 100 is provided with a mounting wall 130, the mounting wall 130 is located behind the reagent tube placing member 210 along a predetermined direction, the buffering assembly 500 includes a first buffering member 510, a second buffering member 520, a first reset resilient piece 530 and a reset torsion spring 540, one end of the first buffering member 510 is rotatably connected to the mounting wall 130, the other end of the first buffering member 510 is rotatably connected to one end of the second buffering member 520, one end of the first reset resilient piece 530 is fixedly connected to the mounting wall 130, the other end of the first reset resilient piece 530 is fixedly connected to the second buffering member 520, and the reset torsion spring 540 is disposed at a rotation center of the first buffering member 510;

wherein the second buffering member 520 can be pressed by the reagent tube placing member 210 to force the first buffering member 510 to rotate in a first rotating direction, and the return torsion spring 540 is used to provide potential energy for the first buffering member 510 to rotate in a second rotating direction, which is opposite to the first rotating direction;

the first reset resilient piece 530 is used for providing potential energy for the second buffer 520 to move along a preset direction.

Specifically, the first rotation direction is a clockwise rotation direction, and the second rotation direction is a counterclockwise rotation direction.

In this way, when the reagent tube placing member 210 is restored, the reagent tube placing member 210 can apply pressure to the second buffering member 520 to move the second buffering member 520 in a direction opposite to the predetermined direction, so as to force the first buffering member 510 to rotate in the clockwise direction, and since the reset torsion spring 540 is disposed at the rotation center of the first buffering member 510, and the reset torsion spring 540 can provide potential energy for the first buffering member 510 to rotate in the counterclockwise direction, so as to reset the first buffering member 510. Since the first reset resilient piece 530 can provide potential energy for the second buffer 520 to move along the predetermined direction, the second buffer 520 can move along the predetermined direction for resetting. When the first and

second buffering members

510 and 520 are completely reset, the first and

second buffering members

510 and 520 can apply a pushing force to the reagent tube placing member 210 in a predetermined direction, so as to weaken a resilient force of the reagent tube placing member 210 in a direction opposite to the predetermined direction. When the reagent tube placing member 210 repeatedly contacts with the second buffering member 520, the pushing force applied to the reagent tube placing member 210 along the preset direction by the first buffering member 510 and the second buffering member 520 can gradually offset the resilience of the reagent tube placing member 210 along the opposite direction of the preset direction, so as to achieve the restoration of the reagent tube placing member 210, and in the process, the rigidity of the acting force between the reagent tube placing member 210 and the buffering assembly 500 is reduced due to the elastic action of the reset torsion spring 540 and the first reset elastic sheet 530, so that the buffering assembly 500 can play a role in buffering the reagent tube placing member 210, and the safety of the reagent tube stored in the reagent tube placing member 210 is ensured.

As shown in fig. 2 and 8, in one embodiment, the buffering assembly 500 further includes a third buffering member 550 and a second reset spring 560, the third buffering member 550 and the second buffering member 520 are spaced apart from each other along the height direction of the reagent tube placing member 210, the third buffering member 550 and the second buffering member 520 are both rotatably connected to one end of the first buffering member 510 away from the reset torsion spring 540, the third buffering member 550 is located below the first buffering member 510, and the second buffering member 520 is located above the first buffering member 510. The second reset spring 560 and the first reset spring 530 are arranged at intervals along the height direction of the reagent tube placing member 210, one end of the second reset spring 560 is fixedly connected to the mounting wall 130, and the other end of the second reset spring 560 is fixedly connected to the third buffer member 550;

the second reset resilient tab 560 is used for providing potential energy for the third buffer 550 to move along a predetermined direction.

Since the third cushion member 550 and the second cushion member 520 are both rotatably connected to the end of the first cushion member 510 away from the return torsion spring 540, the third cushion member 550 is located below the first cushion member 510, and the second cushion member 520 is located above the first cushion member 510, when the reagent tube placing member 210 returns to the original position, pressure can be simultaneously applied to the second cushion member 520 and the third cushion member 550, and the second cushion member 520 and the third cushion member 550 can simultaneously move along the opposite direction of the predetermined direction. And since the second reset resilient tab 560 can provide potential energy for the third buffer member 550 to move along the preset direction, the third buffer member 550 can move along the preset direction to reset. At this time, since the second buffer member 520 and the third buffer member 550 move in the preset direction at the same time to reset, the buffer assembly 500 can apply more thrust in the preset direction to the reagent tube placing member 210, so that the resilient force of the reagent tube placing member 210 in the opposite direction to the preset direction can be weakened more quickly. And the third buffer member 550 and the second buffer member 520 are spaced apart from each other in the height direction of the reagent tube housing member 210, so that the rigidity of the acting force between the reagent tube housing member 210 and the buffer assembly 500 can be further reduced, thereby further enhancing the buffer effect of the buffer assembly 500 on the reagent tube housing member 210 and ensuring the safety of the reagent tubes stored in the reagent tube housing member 210.

As shown in fig. 7, in one embodiment, there are two sets of cushion members 500, and the two sets of cushion members 500 are arranged in parallel and spaced apart from each other along the width direction of the guide inclined wall 120.

The two sets of buffer assemblies 500 can apply more pushing force to the reagent tube placing member 210 in the predetermined direction, thereby further accelerating the weakening of the resilience force of the reagent tube placing member 210 in the direction opposite to the predetermined direction. Since the two buffer assemblies 500 are arranged in parallel and at intervals along the width direction of the guide inclined wall 120, the local stress of the single buffer assembly 500 on the reagent tube accommodating member 210 can be reduced, the damage of the buffer assembly 500 on the reagent tube accommodating member 210 can be reduced, and the safety of the reagent tube stored in the reagent tube accommodating member 210 can be ensured.
