Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, it relates to an automatic sample injection assistance device for colorectal cancer screening. Background Art

[0002] Biochemical tests are often required for colorectal cancer screening of fecal samples to preliminarily determine whether a patient has colorectal cancer. Although the biochemical test equipment for fecal samples on the market is accurate in detection, it does not consider the quantity of samples, resulting in cumbersome and time-consuming manual loading of samples.

[0003] As Figure 4 shown, it is a structural schematic diagram of a manual sample injection device on an existing biochemical test equipment for fecal samples. It includes a tray 100 that can be pushed into the equipment. Four horizontally extending front-back material grooves 101 are provided on the tray 100. A material rack 102 with an upward-facing notch is embedded in the material groove 101. A row of five sample jacks 103 arranged horizontally front-back is provided on the material rack 102. Each time a biochemical test of a fecal sample is carried out, twenty samples need to be manually loaded for testing, which is time-consuming and cumbersome to pick up.

[0004] Moreover, with the gradual increase in the popularity of colorectal cancer screening, the number of fecal samples to be tested received by the testing center on a single day is large, the testing pressure is high, and the overall effect is not good. Accordingly, the present invention proposes an automatic sample injection assistance device for colorectal cancer screening. Summary of the Invention

Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0017] The present invention will be further described below in conjunction with the drawings and preferred embodiments.

[0018] Embodiment 1

[0019] See Figures 1 to 4 As shown, an automatic sampling auxiliary device for colorectal cancer screening involved in this embodiment includes a vibrating disk 1 and a conveying rail 2 for feeding in cooperation with the vibrating disk 1. The conveying rail 2 extends horizontally from left to right. One end of the conveying rail 2 facing away from the vibrating disk 1 is provided with an inserting platform 3, and a transfer and insertion mechanism 4 is provided between the inserting platform 3 and the conveying rail 2; a baffle 5 is provided at the end of the conveying rail 2, and a vision detection device 6 is provided above the end of the conveying rail 2; the bottom of the inserting platform 3 is provided with a first linear module 7 for controlling its horizontal left and right movement and a second linear module 8 for controlling its horizontal front and back movement. The first linear module 7 is arranged on the sliding table of the second linear module 8, and the inserting platform 3 is arranged on the sliding table of the first linear module 7; a robotic arm 9 is also included.

[0020] Furthermore, the transfer and insertion mechanism 4 includes a suspension 10 extending horizontally from left to right. A first linear reciprocating motion mechanism 11 for controlling its vertical up and down movement is provided on the suspension 10. A slide rail 12 also extending horizontally from left to right is provided on the suspension 10. A slide seat 13 is slidably connected to the slide rail 12. A rotary cylinder 14 with a horizontally extending front and back rotation axis is provided on the slide seat 13. A double-end air chuck that rotates with it is provided on the rotating table of the rotary cylinder 14. A second linear reciprocating motion mechanism 15 for controlling the slide seat 13 to reciprocate on the slide rail 12 is also provided on the suspension 10.

[0021] Further, the double-end air chuck includes a chuck base 16. A first air guide cavity 17 extending vertically up and down is formed in the chuck base 16. Second air guide cavities 18 connected to the inside thereof are respectively provided above and below the first air guide cavity 17. The diameter of the second air guide cavity 18 is larger than that of the first air guide cavity 17. A flow blocking ball 19 is slidably connected in the second air guide cavity 18. An air inlet channel 20 with one end communicating with the outside and the other end communicating with the first air guide cavity 17 is formed in the chuck base 16. An air outlet channel 21 with one end communicating with the outside and the other end communicating with the second air guide cavity 18 is further formed in the chuck base 16. A first clamping block 22 extending upward from its top and a second clamping block 23 extending downward from its bottom are provided on one side of the chuck base 16. A first clamping channel 24 with one end communicating with the outside and the other end communicating with the air outlet channel 21 is formed in the first clamping block 22. A second clamping channel 25 with one end communicating with the outside and the other end communicating with the air outlet channel 21 is formed in the second clamping block 23.

[0022] Further, the flow blocking ball 19 is a steel ball with a soft rubber layer coated on its surface.

[0023] Further, an illumination unit 26 is provided on the visual detection device 6.

[0024] In this embodiment, by placing four groups of material racks 102 on the inserting platform 3 and controlling their corresponding front-back, left-right movements by two linear modules at the bottom of the inserting platform 3, the sample insertion into each sample insertion hole 103 is realized. Among them, by operating the vibrating disk 1, the vibrating disk 1 discharges materials (samples to be measured). The materials are output along the conveying material rail 2 until blocked by the baffle 5. Then, the visual detection device 6 determines whether the head is facing left. If so, the transfer and insertion mechanism 4 directly performs normal clamping; if not, it rotates 180° by the rotary cylinder 14 and then performs normal clamping.

[0025] Among them, the working principle of the transfer and insertion mechanism 4 is as follows: The first linear reciprocating motion mechanism 11 controls the suspension 10 to perform reciprocating motion in the vertical up and down direction; the second linear reciprocating motion mechanism 15 controls the sliding seat 13 to perform reciprocating motion in the horizontal left and right direction. When it is determined that the head of the sample to be measured is facing left, the rotary cylinder 14 does not rotate first, and one end of the double-end air chuck is used for material adsorption and transfer. Then, the rotary cylinder 14 rotates clockwise by 90°, and after the material is located above the corresponding sample insertion hole 103, automatic insertion is realized through downward movement; when it is determined that the head of the sample to be measured is facing right, the rotary cylinder 14 rotates 180° first, and the other end of the double-end air chuck is used for material adsorption and transfer. Then, the rotary cylinder 14 rotates counterclockwise by 90°, and after the material is located above the corresponding sample insertion hole 103, automatic insertion is realized through downward movement.

[0026] By using double-ended air chucks at different ends to pick up and transfer materials in different orientations, the materials can be prevented from contacting the components, and it is also convenient to insert the samples, eliminating the need for an additional secondary transfer mechanism.

[0027] Among them, the working principle of the double-ended air chuck is as follows: when the second chuck 23 is located below the first chuck 22, the choke ball 19 above the first air guide cavity 17 closes the upper air port, so that when a negative pressure is provided to the air inlet channel 20, the first picking channel 24 is blocked, and a negative pressure is formed at the end of the second picking channel 25 to realize negative pressure suction of the sample to be tested; when the second chuck 23 is located above the first chuck 22, the choke ball 19 (which has been switched up and down) above the first air guide cavity 17 closes the upper air port, so that when a negative pressure is provided to the air inlet channel 20, the second picking channel 25 is blocked, and a negative pressure is formed at the end of the first picking channel 24 to realize negative pressure suction of the sample to be tested.

[0028] Among them, by setting the choke ball 19 as a steel ball with a soft rubber layer coated on its surface, the sealing effect is better.

[0029] Among them, by adding an illumination unit 26 to the visual inspection device 6, it plays an illuminating role.

[0030] The automatic sample loading auxiliary device for colorectal cancer screening involved in the present invention, through the linkage of various mechanisms, enables the samples to be tested sent out by the vibrating disk to be transferred one by one by the transfer and insertion mechanism into the sample insertion holes of the racks preset on the insertion platform. After twenty samples to be tested are fully loaded, the four groups of racks are clamped off from the insertion platform by the robotic arm at the end of the device and finally placed into the corresponding slots of the tray, realizing the automatic sample loading function. The overall function is complete and the practicability is strong.
