Description

Technical Field

[0001] This invention relates to the field of testing sampling devices, specifically a testing sampling device and method for medical testing. Background Technology

[0002] Sampling for medical microbiology testing must follow strict procedures to ensure accurate and reliable results. Sampling is the starting point of the entire testing process, and its quality directly affects the detection rate of pathogens and the accuracy of clinical diagnosis. After the medical microorganisms have been cultured, they are generally stored in test tubes (multiple tubes are used), and samples are taken from these stored tubes for testing.

[0003] Existing medical testing sampling devices require sampling from test tubes stored inside test tube supports when testing for microorganisms located inside the tubes. Traditional sampling methods rely heavily on manual sample collection, verification, and transfer, which is insufficient for high-throughput testing demands. Furthermore, in clinical practice, processing large quantities of in-tube samples involves repetitive operations by medical personnel, increasing the risk of errors such as sample confusion, labeling errors, and inconsistent sample volumes, thus affecting the accuracy and reproducibility of test results.

A clamping sampling component is installed on the side of the lifting slide, and a vision capture component is installed on the outside of the L-shaped support body.

[0011] As a preferred embodiment of the present invention, the clamping sampling component includes: A first horizontal cylinder is installed at both ends of the side of the lifting slide, and its output end is connected to a clamping drive source. Another clamping drive source is installed at the center of the side of the lifting slide; A lifting slide plate is connected to the output end of the clamping drive source. Angled grooves are provided on the left and right sides inside the lifting slide plate. The lifting slide plate extends into the interior of the clamping component, which is slidably connected to the side of the lifting slide block. The side pressure claw is movably connected to the lifting slide plate through an oblique groove.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In medical laboratory sampling devices and methods, an automated system is used to move the side clamping claw vertically, horizontally, and longitudinally. The claw moves above the test tube and automatically clamps and fixes it, ensuring random sampling of test tubes located inside the storage rack. This system can handle hundreds of clamping / sampling actions, far exceeding the speed of manual operation, thus improving efficiency and throughput. It also eliminates the risk of sample confusion, sampling deviation, or contamination caused by operator fatigue, lack of concentration, or differences in technique. Furthermore, during the sampling and clamping process, the distance between adjacent clamped and sampled test tubes can be adjusted according to their size, allowing for simultaneous sampling and clamping of multiple test tubes of varying sizes. This effectively improves the efficiency of test tube clamping and sampling, ensuring the accuracy and repeatability of test results. 2. In medical laboratory sampling devices and methods, when clamping and sampling test tubes stored inside a test tube storage rack, the combined use of a visual inspection module and a focusing lens can quickly identify the location, morphology, color, and density distribution of bacterial colonies. This helps determine whether there is contamination, abnormal growth, or a concentrated area of ​​target bacterial colonies, locating the dominant bacterial colony area within the test tube and reducing ineffective operations. Simultaneously, if unexpected color, turbidity, or foreign matter is detected, the sampling operation for that test tube can be stopped immediately, ensuring that all sampled test tubes are valid samples. 3. In medical laboratory sampling devices and methods, when sampling and clamping test tubes stored inside test tube storage racks, multiple test tube storage racks and their stored test tubes can be placed against each other on top of the rack using automated equipment. This reduces the movement distance of the automated sampling structure during sampling, increases sampling speed, and is particularly suitable for high-throughput sample processing scenarios (clinical testing). Simultaneously, the adjacent test tube storage racks form a stable array, helping the automated sampling structure accurately position the test tubes inside, reducing the risk of accidental grasping, slippage, or breakage.

[0020] Example 1

[0021] Please see Figures 1-10 A medical testing sampling device includes a frame 10; a horizontal feeding structure 20 installed on one side of the top of the frame 10, with a test tube storage rack 30 clamped and fixed inside the horizontal feeding structure 20, and the test tube storage rack 30 being transported and moved to the top of the frame 10; an automated testing sampling structure 40 installed on the top of the frame 10, the automated testing sampling structure 40 clamping and sampling test tubes located inside the test tube storage rack 30, the automated testing sampling structure 40 including: a bidirectional conveying assembly 401 installed on the top of the frame 10; a lifting sampling assembly 402 installed on the side of the bidirectional conveying assembly 401 by screws; a clamping sampling assembly 403 installed on the side of the lifting sampling assembly 402, with a test tube clamped and fixed at the bottom of the clamping sampling assembly 403; and a visual capture assembly 404 installed on the side of the lifting sampling assembly 402, wherein the visual capture assembly 404 performs visual capture and testing of the sample inside the test tube.

[0022] It should be noted that the test tube storage rack 30 has two hollow spaces inside, and multiple test tubes are stored equidistantly inside the test tube storage rack 30.

[0023] The working principle is as follows: When sampling test tubes (containing microorganisms) stored inside the test tube storage rack 30, the test tubes are first placed inside the test tube storage rack 30. The horizontal feeding structure 20 clamps and fixes the test tube storage rack 30 and moves it horizontally to the corresponding position at the top of the frame 10. Then, the bidirectional conveying component 401 and the lifting sampling component 402 are activated, driving the visual capture component 404 mounted on the side of the lifting sampling component 402 to move vertically, horizontally, and longitudinally, approaching the test tube storage rack 30 to visually capture and inspect the test tubes (containing microorganisms) inside. After completing the visual capture and inspection of the test tubes (containing microorganisms), the bidirectional conveying component 401 and the lifting sampling component 402 are activated again, driving the clamping sampling component 403 to move vertically, horizontally, and longitudinally, moving to the top of the test tubes to clamp and sample the test tubes stored inside the test tube storage rack 30, realizing automatic and intelligent sampling and clamping operations.

[0024] For details, please refer to the following: Figure 4 The horizontal feeding structure 20 includes a horizontal slide rail system 201, which is installed on one side of the top of the frame 10. A horizontal electric slider 202 is installed on the top of the horizontal slide rail system 201, and a longitudinal electric push rod 203 is installed on the top of the horizontal electric slider 202. An electric gripper 204 is connected to the output end of the longitudinal electric push rod 203, and a test tube storage rack 30 is clamped and fixed on the inner side of the electric gripper 204.

[0025] In the medical testing sampling device of the present invention, after the test tube storage rack 30 is moved to the top of the frame 10, the test tube storage rack 30 is first moved to the inside of the electric gripper 204, and the electric gripper 204 squeezes and fixes the test tube storage rack 30 and the test tubes inside it. Then, the horizontal slide rail system 201 is activated, driving the top of the horizontal slide rail system 201 to move horizontally along the electric gripper 204 and the test tube storage rack 30 mounted on the horizontal electric slider 202 to the top of the frame 10. At this time, through the design of the longitudinal electric push rod 203, the test tube storage rack 30 can be moved to different positions on the top of the frame 10, so that multiple test tube storage racks 30 can be placed together in contact with each other.

[0026] For details, please refer to the following: Figure 5 and Figure 6 The bidirectional conveying assembly 401 includes an upper support 4011, which is installed on the left and right sides of the top of the frame 10 by screws.

A transverse slide seat 4015 is installed on the side of the transverse slide rail system 4014 and is slidably connected to the side of the transverse slide rail system 4014.

[0027] In this design, an I-beam bracket 40151 is mounted on the side of the transverse slide block 4015 by screws, and a lifting sampling assembly 402 is mounted on the side of the I-beam bracket 40151 by screws.

[0028] In the medical testing sampling device of the present invention, when visual inspection and clamping sampling are performed on the test tube, the longitudinal slide rail system 4012 is activated to operate, driving the sliding seat 4013 on the side of the longitudinal slide rail system 4012 to move longitudinally, adjusting the position of the clamping sampling component 403 and the visual capture component 404 in the longitudinal direction; the transverse slide rail system 4014 is activated to operate, driving the transverse sliding seat 4015 to move laterally, adjusting the position of the clamping sampling component 403 and the visual capture component 404 in the transverse direction.

[0029] For details, please refer to the following: Figure 7 The lifting sampling component 402 includes an L-shaped support body 4021, which is mounted on the side of an I-beam bracket 40151 by screws. A belt drive system 4022 is provided inside the L-shaped support body 4021, and a lifting slide 4023 is installed on the outside of the belt drive system 4022. The lifting slide 4023 is slidably connected to the side of the L-shaped support body 4021 and moves up and down through the belt drive system 4022. A clamping sampling component 403 is installed on the side of the lifting slide 4023, and a vision capture component 404 is installed on the outside of the L-shaped support body 4021.

[0030] In the medical testing sampling device of the present invention, when visual inspection and sampling are performed near the test tube, the belt drive system 4022 is activated to operate, driving the lifting slide 4023 installed on the outside of the belt drive system 4022 to move vertically up and down, and adjusting the height of the clamping sampling component 403 installed on the side of the lifting slide 4023.

[0031] For details, please refer to the following: Figure 7 , Figure 8 , Figure 9 and Figure 10 The clamping and sampling assembly 403 includes a first horizontal cylinder 4031, which is installed at the left and right ends of the side of the lifting slide 4023. The output end of the first horizontal cylinder 4031 is connected to a clamping drive source 4032. Another clamping drive source 4032 is installed at the center of the side of the lifting slide 4023. A lifting slide plate 4033 is connected to the output end of the clamping drive source 4032. The left and right sides of the interior of the lifting slide plate 4033 are provided with inclined grooves 4034. The lifting slide plate 4033 extends into the interior of the clamping component 4035, which is slidably connected to the side of the lifting slide 4023. A side pressure claw 4036 is movably connected to the lifting slide plate 4033 through the inclined grooves 4034. The side pressure claw 4036 is slidably connected to the left and right sides of the clamping component 4035, and a test tube is clamped and fixed on the inner side of the side pressure claw 4036.

[0032] In this design, the lifting slide plate 4033 has a guide rod 40331 that slides through the clamping component 4035. The guide rod 40331 is connected to the output end of the second horizontal cylinder 40332, which is installed on the side of the lifting slide block 4023.

[0033] In the medical testing sampling device of the present invention, when clamping and sampling a test tube, the distance between the two first horizontal cylinders 4031 mounted on the side of the first horizontal cylinder 4031 and the middle first horizontal cylinder 4031 can be adjusted by activating the first horizontal cylinder 4031. When clamping and sampling a test tube, the clamping drive source 4032 is activated, driving the lifting slide plate 4033 connected to the output end of the clamping drive source 4032 to move up and down inside the clamping component 4035. At this time, through the inclined grooves 4034 opened on the left and right sides inside the lifting slide plate 4033, the side pressure claws 4036 movably arranged inside the inclined grooves 4034 can be driven to extend and retract inside the clamping component 4035, clamping and sampling the test tube placed inside the side pressure claws 4036.

[0034] It should be noted that when the first horizontal cylinder 4031 operates to adjust the position of the two clamping drive sources 4032, the lifting slide plate 4033 can extend and retract within the guide rod 40331. At this time, the position of the guide rod 40331 can be adjusted by activating the second horizontal cylinder 40332, ensuring that it remains in a sliding connection with the lifting slide plate 4033, thus guiding the lifting and lowering movement of the lifting slide plate 4033.

[0035] For details, please refer to the following: Figure 7 The visual capture component 404 includes a side pressure seat 4041, which is mounted on the side of the L-shaped bracket 4021 by screws. A visual inspection module 4042 is mounted on the side of the side pressure seat 4041. The detection end of the visual inspection module 4042 is connected to a focusing lens tube 4043, which is oriented towards the test tube and performs visual capture and inspection of the sample in the test tube.

[0036] In the medical testing sampling device of the present invention, the design of the visual detection module 4042 and the focusing lens tube 4043 enables visual capture and testing of microorganisms located in the test tube.
