Description

Technical Field

[0001] The utility model relates to the field of in vitro diagnostic automation equipment, in particular to a reagent disk driving mechanism and a mixing device. Background Art

[0002] With the development of analytical fields such as biological detection technology and in vitro diagnostic technology, the processing of samples has gradually become more complicated. A common processing method is to use a reagent containing a magnetic bead solution to fully mix the sample and react, and use the magnetism of the magnetic beads to separate the desired test objects in the sample. In the prior art, a non-contact mixing method is usually used, in which the transmission mechanism rotates the magnetic bead bottle to mix the reagents in the magnetic bead bottle, which has the advantage of preventing cross infection and can effectively ensure the accuracy of the test results.

[0003] In the process of non-contact mixing by the mixing device, it is necessary to drive the large pulley to rotate through the transmission mechanism, and then drive the first drive shaft to rotate through the large pulley to realize the rotation and revolution of the magnetic bead bottle in the test kit, and complete the reagent mixing in the magnetic bead bottle. However, in the prior art, the reagent tray drive mechanism has the problem of unreasonable structural layout. The transmission shaft length of the transmission mechanism is longer, which increases the transmission load. For example, the patent document with publication number CN203241422U discloses a reagent tray. The drive motor in the above-mentioned reagent tray needs to pass through the bottom plate and then be connected to the large pulley transmission. In the above-mentioned reagent tray in the prior art, it is necessary to design the drive shaft of the drive motor to be long enough, so that the design will cause the drive shaft to be longer, which increases the transmission load.

[0013] Optionally, a shock-absorbing pad is provided between the motor fixing plate and the bottom plate.

[0014] Optionally, the reagent disk drive mechanism further includes: a support member; the support member is arranged on one side of the base plate where the drive module and the transmission module are installed to form a receiving cavity for receiving the drive module and the transmission module.

[0015] Optionally, the drive module and the transmission module are both mounted on the base plate.

[0016] A mixing device comprises: the above reagent disk driving mechanism.

[0019] A driven gear is arranged on the magnetic bead bottle in the reagent box, and the driven gear is rotatably arranged on the reagent disk along its circumferential direction;

[0020] A fixed gear is fixed on the bottom plate and remains stationary; a first tooth is arranged on the inner periphery of the fixed gear, and the first tooth is matched and connected with the second tooth on the driven gear; the reagent disk is connected to the driving module and is driven to rotate along its circumferential direction to guide the driven gear to rotate and revolve around the center position of the fixed gear.

[0021] Optionally, the mixing device further comprises:

[0022] The driving sleeve is fixedly mounted on the bottom plate, away from the side of the driving module; the fixed gear is mounted on the annular step of the driving sleeve, and the second driving shaft on the transmission module passes through the connecting hole of the driving sleeve and is connected to the reagent disk to drive the reagent disk to rotate.

[0023] Optionally, the magnetic bead bottle and the driven gear are an integrated structure; and / or,

[0024] The fixed gear is an annular arrangement cavity, and the first tooth is arranged on the inner cavity wall of the annular arrangement cavity.

[0025] The technical solution of the utility model has the following advantages:

[0026] 1. The reagent tray drive mechanism provided by the utility model can directly drive the drive module to drive the drive module by arranging the drive module and the transmission module on the side of the bottom plate away from the fixed gear, thereby driving the magnetic bead bottle in the reagent kit to rotate and mix the reagent.

[0027] 2. The reagent tray driving mechanism provided by the utility model, the driver drives the synchronous belt to rotate through the small pulley on the first driving shaft, thereby further driving the second driving shaft on the large pulley through the synchronous belt. Then the reagent tray is driven to rotate through the second driving shaft to mix the reagent.

The above structure can effectively shorten the length of the first driving shaft, thereby effectively reducing the transmission load of the driving shaft.

[0028] 3.

Compared with assembling the drive module and the transmission module on two modules respectively, the above-mentioned structure in the present invention can effectively simplify the difficulty of assembly.

[0032] 7. The mixing device provided by the utility model includes a reagent disk driving mechanism. Therefore, the mixing device has all the advantages of the transmission mechanism.

[0033] 8. The mixing device provided by the utility model is provided with a driven gear on the magnetic bead bottle, and the magnetic bead bottle is rotatably arranged on the reagent disk. Since the driven gear is meshed with the inner periphery of the fixed gear, and the above-mentioned fixed gear remains stationary.
