Description

Technical Field

[0001] This utility model relates to a fully automated fluorescence immunoassay analyzer, and in particular to a device for delivering sample tubes on the analyzer. Background Technology

[0002] A fully automated fluorescence immunoassay analyzer is a medical testing device used for blood testing. The operator places a test tube or vacuum sample tube containing the blood sample into the analyzer. The analyzer extracts the sample from the tube, mixes it with a reagent, and analyzes the blood based on fluorescence after the reaction is complete. Existing fully automated fluorescence immunoassay analyzers require operators to manually place vacuum sample tubes one by one into the instrument, or to place a rack containing multiple vacuum sample tubes into the instrument, and then remove the tubes after sampling. This type of fully automated fluorescence immunoassay analyzer has a low degree of automation, requiring a high level of operator involvement. This not only results in low efficiency and is time-consuming and labor-intensive, but also increases the likelihood of errors due to frequent operation. Utility Model Content

[0003] The purpose of this invention is to provide a sample tube delivery device with a higher degree of automation, so as to improve work efficiency and reduce the probability of human error.

[0004] The sample tube transport device for the fluorescence immunoassay analyzer described in this utility model includes a test tube rack for placing two or more sample tubes in a straight line, an infeed platform and an outlet platform for placing two or more test tube racks side by side, and the infeed platform and outlet platform are set on the same horizontal plane. The outlet of the infeed platform and the inlet of the outlet platform are connected by a detection channel. The outlet of the infeed platform, the detection channel and the inlet of the outlet platform are located on the same straight line and are equipped with positioning baffles to block the test tube rack at the adjacent positions of the three. The detection channel is set opposite to the sampling station for drawing blood samples. There are also an infeed transport mechanism, an outlet transport mechanism and a detection transport mechanism that drive the test tube rack to move along the infeed platform, the outlet platform and the detection channel, respectively. The detection transport mechanism drives the test tube rack to move and moves the sample tubes on the test tube rack one by one to the sampling station.

[0005] The sample tube conveying device for the fluorescence immunoassay analyzer described in this utility model can hold multiple test tube racks on both the infeed and outlet platforms. A detection channel is located between the two platforms, and a sampling mechanism for extracting blood samples from the sample tubes is installed above the detection channel; this location is also known as the sampling station. When using the fluorescence immunoassay analyzer, the operator places the sample tube containing the blood sample onto the test tube rack, and then places the test tube rack horizontally on the infeed platform. Subsequently, the infeed conveying mechanism moves the test tube rack to the position opposite the detection channel. Next, the detection conveying mechanism moves the test tube rack along the conveying channel, making room for subsequent test tube racks. The test tube racks on the detection channel move gradually under the action of the detection conveying mechanism, allowing all sample tubes on the test tube racks to enter the sampling station one by one, enabling the sampling mechanism to extract blood samples from each sample tube. After all sample tubes have been sampled, the test tube rack also enters the outlet platform from the detection channel. The outlet conveying mechanism then moves the test tube rack to the outlet position, where the operator can remove the test tube rack. This fluorescence immunoassay analyzer features a sample tube delivery device. Staff only need to place the test tube rack into the discharge platform, and the sample tube delivery device will automatically move the sample tube to the sampling station and automatically deliver it after sampling. Its high degree of automation can effectively improve work efficiency. Moreover, both the infeed and discharge platforms can hold multiple test tube racks at the same time, allowing staff to pick up and put down the test tube racks more conveniently and calmly, reducing the risk of errors.

[0026] This invention proposes a sample tube delivery device for a fluorescence immunoassay analyzer.

[0027] The sample tube delivery device of the fluorescence immunoassay analyzer in this embodiment includes a test tube rack for placing two or more sample tubes in a straight line, an infeed platform 1 and an outlet platform 2 for placing two or more test tube racks side by side, and the infeed platform and outlet platform are set on the same horizontal plane. The outlet of the infeed platform and the inlet of the outlet platform are connected by a detection channel 3. The outlet of the infeed platform, the detection channel and the inlet of the outlet platform are located on the same straight line and a positioning baffle 4 is installed at the adjacent position to block the test tube rack. The detection channel is set opposite to the sampling station 8 for extracting blood samples. There are also an infeed delivery mechanism 5, an outlet delivery mechanism 6 and a detection delivery mechanism 7 that drive the test tube rack to move along the infeed platform, the outlet platform and the detection channel, respectively. The detection delivery mechanism drives the test tube rack to move and moves the sample tubes on the test tube rack one by one to the sampling station.

[0028] like Figure 1-8 As shown, the feeding platform and the discharging platform are located on the left and right sides of the same side of the fluorescence immunoassay analyzer, so that staff can easily put in and take out the test tube racks. The middle of this side of the fluorescence immunoassay analyzer is the detection channel connecting the feeding platform and the discharging platform. Above the detection channel is a sampling mechanism for extracting blood samples from the sample tubes, which is also the sampling station. At the same time, the detection channel is located inside the feeding platform and the discharging platform, and the outer side can be left for staff to easily put in and take out the test tube racks. When using the fluorescence immunoassay analyzer, the operator places the sample tubes containing blood samples into the test tube rack, and then places the test tube rack horizontally on the feeding platform. The feeding conveyor then moves the test tube rack inward until it reaches the innermost part, where it contacts the positioning baffle, with one end of the rack facing the detection channel. Next, the detection conveyor moves the test tube rack along the conveyor channel and the positioning baffle, leaving space on the inner side of the feeding platform for subsequent test tube racks to enter. The test tube racks on the detection channel move gradually under the action of the detection conveyor, allowing all sample tubes on the rack to enter the sampling station one by one, enabling the sampling mechanism to extract blood samples from each tube. After all sample tubes have been sampled, the test tube rack moves from the detection channel to the innermost part of the discharge platform. The discharge conveyor then moves the test tube rack outward until it reaches the outermost part of the discharge platform, at which point the operator can remove the test tube rack.

[0029] like Figure 2 , 3As shown, the feeding platform 1 has a feeding channel 11 connecting the upper and lower sides along the conveying direction; the feeding conveying mechanism 5 includes a feeding frame 51 installed below the feeding platform, a feeding guide rail 52 parallel to the feeding channel installed on the feeding frame, a feeding slider 53 movably installed on the feeding guide rail, and a feeding motor assembly 54 driving the feeding slider to move. The feeding slider is connected to a feeding push rod 55, and a feeding push plate 56 is hinged to the feeding push rod by a torsion spring. One end of the feeding push plate can rotatably extend out of the feeding channel or retract under the feeding channel. The torsion spring applies a force to the feeding push plate to make it extend out of the feeding channel. The other end of the feeding push plate is provided with a limiting part 57 that abuts against the feeding push rod and makes the feeding push plate continuously extend out of the feeding channel. Figure 4 As shown, this allows the feed pusher plate to fixably push the test tube racks on the feed platform inwards, i.e., to the outlet end of the feed platform. At this time, the feed motor assembly drives the feed pusher plate to move outwards through the feed slider and feed pusher rod. When the feed pusher plate contacts other test tube racks, it is compressed and retracts below the feed channel until it moves to the outermost position. Then, under the action of the torsion spring, it extends out of the feed channel again and applies a pushing action to the remaining test tube racks. This type of feeding and conveying mechanism is fast and accurate, which helps to improve work stability and efficiency. The feed motor assembly 54 can be a motor and a lead screw and nut pair, or it can be as follows: Figure 3 The motor and conveyor belt shown are shown; at the same time, a feed sensor 58 can also be installed on the feed rack 51 to detect the movement of the feed pusher 54 to both ends of the feed channel 11, so as to further improve the working accuracy.

[0030] Similarly, such as Figure 5 , 6 As shown, the discharge platform 2 is provided with a discharge channel 21 connecting the upper and lower sides along the conveying direction, and the positioning baffle 4 has a slot opposite to the discharge channel; the discharge conveying mechanism 6 includes a discharge frame 61 installed below the discharge platform, a discharge guide rail 62 installed on the discharge frame parallel to the discharge channel, a discharge slider 63 movably installed on the discharge guide rail, and a discharge motor assembly 64 that drives the discharge slider to move. The discharge slider is connected to a discharge push rod 65, which is located behind the positioning baffle and moves through the slot and along the discharge channel as the discharge motor assembly works, thereby pushing the test tube rack outward to the outside of the discharge platform; this type of discharge conveying mechanism can be better hidden inside the machine, and compared with the feeding conveying mechanism, it no longer needs to install a hinged feeding push plate on the discharge push rod, but directly uses the discharge push rod to push the test tube rack, which has better working stability and service life. Similarly, the discharge motor assembly 64 can be a motor and a conveyor belt, and the discharge rack 61 can also be equipped with a discharge sensor 66 for detecting the working position of the discharge push rod 65.

[0031] like Figure 7As shown, the bottom surface of the test tube rack is provided with several push recesses at intervals. The detection channel 3 has a detection through-slot 31 connecting the upper and lower sides along the conveying direction. The detection conveying mechanism 7 includes a detection frame 71 installed below the detection channel, a detection guide rail 72 installed on the feed frame parallel to the detection through-slot, a detection slider 73 movably installed on the detection guide rail, and a detection motor assembly 74 driving the detection slider. The detection slider is connected to a detection push rod 75, and a detection push plate 76 is hinged to the detection push rod. The detection push plate is inclined, with one end passing through the detection through-slot and extending into the push recess. A spring 77 is also installed between the end of the detection push plate and the detection push rod. The end of the detection pusher plate is inserted into the pushing recess and moves towards the discharge platform under the drive of the detection motor assembly, thereby pushing the test tube rack a specific distance. This allows the sample tubes on the test tube rack to move one by one to the sampling station. After the required movement distance for one sample tube is completed, the detection motor assembly drives the detection pusher plate towards the feeding platform. The detection pusher plate inserts into the adjacent pushing recess, thus continuing to push the test tube rack until all sample tubes on the test tube rack have been sampled. Finally, the test tube rack is pushed to the discharge platform. This detection conveying mechanism works in conjunction with the test tube rack to stably move the sample tubes on the test tube rack one by one to the sampling station, thereby ensuring the stability and accuracy of the operation. Similarly, the detection motor assembly 74 can be a motor and a conveyor belt, and the detection frame 71 can also be equipped with a detection sensor 78 to detect the working position of the detection pusher plate 76.

[0032] like Figure 8 As shown, there is an adjustment mechanism 9 for adjusting the orientation of the sample tube. The adjustment mechanism includes a rotatable adjustment wheel 91 and a pressing wheel 92 mounted on both sides of the inlet end of the detection channel 3. The axes of the adjustment wheel and the pressing wheel are arranged vertically. There is also a first motor 93 that drives the pressing wheel to push the sample tube into contact with the adjustment wheel, a second motor 94 that drives the adjustment wheel to rotate and drives the sample tube to rotate, and a reader that detects the label information on the sample tube. This makes the label on the sample tube face the reader so that the recorded information on the sample tube can be obtained and accurately correspond to the source of the blood sample. This eliminates the need for staff to place the sample tube into the test tube rack in a specific orientation, thereby further improving the degree of automation and ease of operation. Two clamping rollers 92 are mounted side by side on the directional frame 95. They act on the sample tube and cooperate with the directional rollers to form a three-point positioning, thereby improving the accuracy of the sample tube orientation. The directional frame 95 is also equipped with a steering sensor 96 for detecting the working position of the clamping rollers 92. At the same time, a movable push rod 97 is installed on the directional frame between the two clamping rollers. One end of the push rod facing the sample tube is rounded, and the other end is connected to the directional frame with a spring. The spring applies a force to the push rod to move it toward the sample tube. The push rod further improves the working stability of pushing the sample tube, and its rounded end does not obstruct the rotation of the sample tube.

[0033] like Figure 1 As shown, a queue-jumping detection rack 10 is installed between the feeding platform 1 and the discharging platform 2, and a queue-jumping detection seat 20 for placing sample tubes is also provided. The queue-jumping detection seat is movably installed on the queue-jumping detection rack opposite to the sampling station, and the direction of movement of the queue-jumping detection seat is perpendicular to the conveying channel, so that temporary or urgently needed sample tubes can be queued for detection through the queue-jumping detection rack and queue-jumping detection seat to meet specific needs.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
