Description

Technical Field

[0001] This utility model specifically relates to an automatic puncture and mixing sample strip holder injection device. Background Technology

[0002] In clinical medical testing, biological research, and other fields, vacuum blood collection tubes are the most commonly used containers for collecting and storing blood, body fluids, and other samples. To ensure the accuracy of test results, samples must be thoroughly mixed before analysis to ensure that the various components in the sample are evenly distributed.

[0003] Currently, the mixing and pretreatment of vacuum blood collection tube samples in laboratories are mainly carried out manually or using semi-automatic mixing equipment. Manual operation is extremely inefficient, labor-intensive, and the consistency of mixing depends entirely on the operator's experience and sense of responsibility, making standardization difficult and prone to affecting test quality due to insufficient or excessive mixing. Furthermore, manual operation increases the risk of biosafety exposure. Existing semi-automatic equipment mostly requires pre-capping treatment before mixing the sample, offering limited efficiency improvement and posing a risk of sample misplacement.

[0004] Therefore, it is necessary to invent an automatic puncture and mixing sample strip holder injection device to solve the above problems. Utility Model Content

The mounting plate has a horizontal guide rail frame above it and a horizontal guide rail below it. The automatic puncture assembly is mounted on the horizontal guide rail. The mounting plate has a retraction assembly, one end of which is placed between the test tube strip rack and the hemolysis pool. The automatic puncture assembly includes a longitudinal guide rail frame, one side of which is mounted on the transverse guide rail.

[0008] Preferably, the retraction assembly includes a retraction motor fixed to the back of the mounting plate, one end of the retraction motor is connected to a retraction rod, and the end of the retraction rod is placed between the test tube strip holder and the hemolysis pool.

[0009] Preferably, a transverse moving clamp matching the transverse guide rail is provided on one side of the longitudinal guide rail frame. The top of the guide rod passes through the motor frame and is connected to the linear motor. A support base is also installed on one side of the bottom of the longitudinal guide rail frame. The bottom of the guide rod is fixed on the support base. Multiple positioning rods are also installed between the motor frame and the support base. The longitudinal moving plate and the positioning plate are both located outside the guide rod and the positioning rod. The sampling needle is fixed at one end of the longitudinal moving plate and passes through the bottom of the positioning plate.

[0010] Preferably, the positioning plate has a sampling hole on one side, and the sampling needle passes through the sampling hole.

[0011] Preferably, the transverse guide rail frame is equipped with a transverse moving motor, which is connected to the transverse moving belt on the back of the mounting plate. The transverse moving belt drives the longitudinal guide rail frame to move on the transverse guide rail.

[0012] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are: 1. The linear motor of this utility model drives the longitudinal moving plate through the guide rod to precisely raise and lower the sampling needle. In conjunction with the transverse moving motor, it drives the longitudinal guide rail frame to move along the transverse guide rail. This enables full automation of the process from test tube puncture to sample extraction and transfer to the hemolysis pool, eliminating the need for manual operation of each test tube. It is especially suitable for batch sample processing scenarios with multiple test tubes.

The transverse guide rail frame and the transverse moving clamp plate of this utility model cooperate to limit the transverse movement trajectory of the longitudinal guide rail frame; the guide rod and the positioning rod together limit the lifting trajectory of the longitudinal moving plate. The double guiding structure avoids the sampling needle from deviating during the movement and ensures that the puncture position is accurately aligned with the test tube opening; the positioning plate is fixed below the guide rod and placed above the test tube. The sampling needle needs to pass through the sampling hole of the positioning plate for puncture, which not only avoids the sampling needle from shaking due to vibration, but also accurately controls the puncture depth and ensures the consistency of each sampling.

[0023] In this embodiment, the base plate 1 serves as the foundation for the device. Multiple positioning and mounting posts 25 fix the test tube rack base plate 21 to its top side, ensuring the stability of the test tube rack mounting assembly 2. A test tube rack 22 is embedded in the top groove of the test tube rack base plate 21.

[0026] Specifically, the back of the mounting plate 3 is fixed with a retraction motor 51, the output end of which is connected to a retraction rod 52. The end of the retraction rod 52 extends between the test tube rack 22 and the hemolysis pool 24 for auxiliary position calibration and resetting.

[0027] Specifically, the test tube 23 containing the sample is placed into the test tube mounting slot 26 of the test tube rack 22, ensuring that the test tubes 23 are in a uniform position.

The linear motor 43 drives the longitudinal movement plate 46 to descend via the guide rod 45, and the sampling needle 47 precisely punctures the test tube 23 along the sampling hole 481 of the positioning plate 48. After sample extraction, the linear motor 43 drives the sampling needle 47 to rise and reset.

The retraction motor 51 drives the retraction rod 52 to move, pushing the test tube rack 22 to the calibration position, preparing for the next operation, and completing the batch processing of multiple test tubes in a cycle.

[0028] In this embodiment, the lateral movement motor 33 and the linear motor 43 work together to achieve fully automated operation of the sampling needle 47 for lateral positioning, longitudinal puncture, sampling and transfer to the hemolysis pool, without the need for manual intervention. This is especially suitable for batch processing of multiple test tubes, which greatly reduces labor costs and operation time.

[0029] In this embodiment, the transverse guide rail 32 and the transverse moving clamp 411 define the transverse moving trajectory, and the guide rod 45 and the positioning rod 49 define the longitudinal lifting trajectory. The dual guidance prevents the sampling needle 47 from deviating. The positioning plate 48 constrains the sampling needle 47 through the sampling hole 481, which not only prevents shaking caused by vibration, but also accurately controls the puncture depth, ensuring that the sampling position is consistent each time and improving the accuracy of sample processing.

[0030] In this embodiment, the test tube rack base plate 21 is fixed by the positioning mounting post 25, and the test tube rack 22 adopts a standardized test tube mounting slot 26, which can be adapted to test tubes of different specifications; the modular design of each component makes it easy to replace the sampling needle 47 or the test tube rack 22, so as to meet the diverse sample processing needs.

[0031] In this embodiment, the retraction component 5 drives the retraction rod 52 through the retraction motor 51 to automatically complete the position calibration of the test tube rack 22 and the equipment reset, avoiding the waiting time for manual adjustment and ensuring the smoothness of continuous batch processing.

[0032] In this embodiment, automated operation reduces direct contact between humans and samples, lowering the risk of biological contamination or chemical reagent damage; the positioning plate 48 and rigid guide rail structure prevent sampling needle breakage or test tube damage, further ensuring operational safety.
