DETAILED DESCRIPTION

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1-3 As shown, a sample rack scheduling mechanism includes a sample rack conveying platform 1, a longitudinal pushing mechanism 2, an emergency sample injection platform 3, a sample rack recovery platform 4, an optical coupler detector, a micro switch, and a sample rack conveying mechanism. The sample rack conveying mechanism conveys the sample rack 5 placed on the sample rack conveying platform 1 to the end of the sample rack conveying platform 1. The longitudinal pushing mechanism 2 disposed at the end of the sample rack conveying platform 1 pushes the sample rack 5 to the detection position of the scanner 6, so that the scanner 6 can scan and identify the sample tubes in the sample rack 5 one by one. After all sample tubes have been scanned, the sample rack 5 is further pushed by the longitudinal pushing mechanism 2 to the sample rack cache mechanism 7. A sample analyzer disposed on one side of the sample rack cache mechanism takes samples from the sample rack cache mechanism 7 and performs tests. In this embodiment, the sample analyzer is disposed on one side of the movement path of the sample rack cache mechanism 7.

[0030] A sample rack conveying platform 1 is provided with a conveying channel 8, into which a sample rack 5 is loaded and slidable. A sample rack output channel 9 is provided at the front end of the conveying channel 8. The sample rack output channel 9 is in communication with the conveying channel 8 and extends perpendicularly to the direction of the conveying channel 8. The sample rack conveying mechanism includes a prying gripper 10 and a prying gripper drive mechanism. The prying grippers 10 are provided on either side of the conveying channel 8. A prying gripper drive mechanism (not shown) is provided at the bottom of the conveying channel 8. The prying gripper drive mechanism can drive the prying gripper 10 to move back and forth between the two sides of the conveying channel 8, thereby driving the sample rack 5 forward within the conveying channel 8 to the sample rack output channel 9 located in front of the longitudinal pushing mechanism 2. The longitudinal pushing mechanism 2 slowly moves the sample rack 5 within the sample rack output channel 9, and after being scanned by a scanner 6, it is moved out to the sample rack buffer mechanism 7. The sample rack output channel 9 is provided at the end of the conveying channel 8 and in front of the longitudinal pushing mechanism 2.

[0031] An optocoupler detector and a microswitch are installed at the end of the sample rack conveyor platform 1, located at the sample rack output channel 9. The optocoupler detector detects the presence of a sample rack on the sample rack conveyor platform 1 and, based on the detection signal, activates the grabber to push the sample rack on the sample rack conveyor platform 1. The microswitch detects the presence of a sample rack in the sample rack output channel 9 and, based on the detection signal, determines whether to activate the longitudinal push mechanism 2 to complete the sample rack 5 injection operation, thereby achieving automated injection. In this embodiment, the optocoupler detector is a through-beam optocoupler.

[0032] An emergency sample introduction platform 3 is located on the side corresponding to the front end of the sample rack transport platform 1. This platform 3 is equipped with an emergency sample rack transport channel (not shown in the accompanying drawings in this embodiment). An emergency sample rack output channel 11 is located horizontally at the front end of the emergency sample rack transport channel, and an emergency sample rack introduction channel 12 is located horizontally at the rear end of the emergency sample rack transport channel. The emergency sample rack output channel 11 is arranged parallel to the sample rack output channel 9, and both are located in front of the longitudinal push mechanism 2, on both sides of the longitudinal push mechanism 2's travel. The introduction end of the emergency sample rack introduction channel 12 is oriented in the opposite direction to the output end of the emergency sample rack output channel 11.

[0033] The longitudinal push mechanism 2 is positioned between the emergency sample rack output channel 11 and the sample rack output channel 9. The scanner 6 is positioned on the side of the output end of the emergency sample rack output channel 11. The scanner 6's detection direction can simultaneously cover the output ends of the emergency sample rack output channel 11 and the sample rack output channel 9, enabling scanning of both emergency sample racks and standard sample racks. It is understood that in other embodiments, the scanner 6 can be positioned elsewhere, as long as it can scan both emergency sample racks and standard sample racks. Positioning the longitudinal push mechanism 2 between the emergency sample rack output channel 11 and the sample rack output channel 9 allows for separate emergency sample racks, avoiding the need for emergency sample racks and standard sample racks to share the output channel, which could easily lead to sample confusion, thereby improving detection efficiency and reducing detection errors. In this embodiment, the longitudinal push mechanism 2 does not push sample racks on both the emergency sample loading platform 3 and the sample rack transport platform 1 simultaneously. Instead, the longitudinal push mechanism 2 can only push sample racks on one of the platforms at a time.

[0034] In this embodiment, the emergency sample rack output channel 11 and the emergency sample rack inlet channel 12 are arranged adjacent to and parallel to each other, forming the emergency sample rack transfer channel. The adjacent arrangement of the emergency sample rack output channel 11 and the emergency sample rack inlet channel 12 saves space and shortens the pushing distance between the emergency sample rack inlet channel 12 and the emergency sample rack output channel 11, thereby preventing the emergency sample racks from tilting or falling during the pushing process.

[0035] In other embodiments, the emergency sample rack transfer channel can be set separately, and the horizontal distance of the emergency sample rack transfer channel can be set as needed, and it is ensured that the extension direction of the emergency sample rack output channel 11 and the extension direction of the emergency sample rack injection channel 12 are perpendicular to the emergency sample rack transfer channel, and the emergency sample rack output channel 11 and the emergency sample rack injection channel 12 are both connected to the emergency sample rack transfer channel.

[0036] A horizontal pushing mechanism 13 is provided on one side of the emergency sample rack inlet channel 12, which is used to push the emergency sample rack being sampled through the emergency sample rack inlet channel 12 to the emergency sample rack output channel 11. A microswitch is provided at the end of the emergency sample rack inlet channel 12, away from its injection end. When an emergency sample rack is inserted into the emergency sample rack inlet channel 12, it contacts the microswitch. Based on the contact signal from the microswitch, the mechanism detects whether a sample rack is present in the emergency sample rack inlet channel 12, activates the horizontal pushing mechanism 13, and pushes the emergency sample rack in the emergency sample rack inlet channel 12 to the emergency sample rack output channel 11.

[0037] The longitudinal pushing mechanism 2 includes a push plate 14 and a sample injection drive mechanism for driving the push plate back and forth. The push plate 14 includes a left push portion 15 and a right push portion 16. The left push portion 15 and the right push portion 16 are integrally formed. The left push portion 15 is positioned on one side of the emergency sample rack output channel 11 and is used to push the emergency sample rack within the emergency sample rack output channel 11 for sample injection. The right push portion 16 is positioned on one side of the sample rack output channel 9 and is used to push the conventional sample rack within the sample rack output channel 9 for sample injection. Specifically, when a sample rack is injected into the emergency sample rack output channel 11 or the sample rack output channel 9, the sample injection drive mechanism drives the push plate 14 forward. The moving push plate 14 then drives the sample rack within the emergency sample rack output channel 11 or the sample rack output channel 9 forward. After being scanned by the scanner 6, the sample rack moves to the sample rack buffer mechanism 7. The sample analyzer then extracts and tests the sample from the sample rack buffer mechanism 7.

[0038] In this embodiment, the sample injection drive mechanism includes a guide rail 17, a driving wheel 18, a transmission wheel 19, a slider 20, a fixed block 21, a fixed frame 22 and a drive motor. The guide rail 17 is arranged parallel to the emergency sample rack output channel 11 and the sample rack output channel 9, and is arranged between the two. The slider 20 is slidably mounted on the guide rail 17 and can slide back and forth along the guide rail. The fixed block 21 is fixedly mounted on the slider 20, the fixed frame 22 is mounted on the fixed block 20, the middle part of the push plate 14 is mounted on the top of the fixed frame 22, and the two sides of the push plate 14 form a left push part 15 and a right push part 16. A driving wheel 18 and a transmission wheel 19 are provided on one side of the guide rail 17; a conveyor belt 23 is provided between the driving wheel 18 and the transmission wheel 19, the fixed block 21 is fixed to the conveyor belt 23 by a clamping piece, and the driving wheel 18 is mounted on the output shaft of the drive motor. The driving motor drives the driving wheel 18 to rotate, thereby driving the conveyor belt 23 between the driving wheel 18 and the conveyor wheel 19 to move back and forth, thereby driving the push plate 14 fixed on the fixed frame 22 to move back and forth along the guide rail. The push plate 14 that moves back and forth drives the sample rack 5 in the emergency sample rack output channel or the sample rack output channel to inject samples.

[0039] A sample rack recovery platform 4 is also provided on the side of the horizontal push mechanism 13 away from the emergency sample rack inlet channel 12. The horizontal push mechanism 13 is positioned between the emergency sample inlet platform 3 and the sample rack recovery platform 4. A recovery guide 24 is defined on the sample rack recovery platform 4. A recovery channel 25 is provided at one end of the recovery guide 24, adjacent to the horizontal push mechanism 13, and is in communication with the recovery guide 24. The recovery channel 25 extends perpendicularly to the recovery guide 24. The sample rack recovery platform 4, the emergency sample inlet platform 3, and the mounting platform for the horizontal push mechanism 13 can be integrally formed or separately provided.

[0040] The horizontal pushing mechanism 13 in this embodiment can push the sample rack 5 on the sample rack recovery platform 4 as well as the sample rack 5 on the emergency sampling platform 3, and the same structure completes the pushing function of the sample racks on different platforms. In other embodiments, different pushing mechanisms can also be configured at the ends of the emergency sampling platform 3 and the sample rack recovery platform 4 as needed to complete the pushing task of the sample rack 5 on each platform. The present invention sets the horizontal pushing mechanism 13 between the sample rack recovery platform 4 and the emergency sampling platform 3, so that the horizontal pushing mechanism 13 can push the sample rack on the sample rack recovery platform 4 as well as the sample rack on the emergency sampling platform 3. The same structure realizes multiple functions, which not only improves the detection efficiency but also reduces the size and cost of the entire instrument. Similarly, the horizontal pushing mechanism 13 in this embodiment does not push the sample racks on the sample rack recovery platform 4 and the emergency sampling platform 3 at the same time. Each push can only achieve the pushing of the sample rack on one of the platforms.

[0041] In this embodiment, a sample rack recovery and advancement mechanism 26 is further provided. This mechanism is located on the side opposite the sample inlet end of the recovery channel 25 and is used to push the sample rack 5 after sampling from the sample rack buffer mechanism 7 into the recovery channel 25. The horizontal advancement mechanism 13 then pushes the sample rack 5 recovered in the recovery channel 25 into the recovery guide trough 24. Since the sample rack recovery and advancement mechanism 26 is a common mechanism in the art, it will not be described in detail.

[0042] The sample rack conveying platform, the emergency sampling platform and the sample rack recovery platform are arranged on the same horizontal line; the sample rack buffer mechanism is arranged on one side of the above-mentioned platform, and is used to move between the platforms to receive the sample rack output from the sample rack conveying platform or the emergency sampling platform to complete the sample injection or carry the sample rack after sampling by the sample analysis instrument to the side of the sample rack recovery platform. The sample rack recovery pushing mechanism pushes the sampled sample rack from the sample rack buffer mechanism into the recovery channel, and finally pushes it to the recovery guide groove for recovery by the horizontal pushing mechanism.

[0043] In addition, this embodiment also provides a sample rack injection mechanism, including a sample rack conveying platform, an emergency injection platform and a longitudinal pushing mechanism; a sample rack output channel is provided on the sample rack conveying platform; an emergency sample rack output channel is provided on the emergency injection platform; the emergency sample rack output channel and the sample rack output channel are arranged in parallel; the extension directions of the emergency sample rack output channel and the sample rack output channel are consistent; the longitudinal pushing mechanism is arranged between the emergency sample rack injection channel and the sample rack output channel, and is used to push the sample rack output channel or the sample rack on the emergency sample rack output channel.

[0044] In addition, this embodiment also provides a sample rack scheduling method, which includes the following steps:

[0045] Transferring the sample rack on the sample rack transfer platform to the sample rack output channel;

[0046] The sample rack in the sample rack output channel is pushed to the sample rack buffer mechanism by the longitudinal pushing mechanism, and the sample rack buffer mechanism completes the scheduling of the sample rack.

[0047] This embodiment also provides a sample rack recovery method, comprising the following steps:

[0048] The sample rack caching mechanism carries the common sample rack and / or emergency sample rack after sampling to the side of the sample rack recovery platform;

[0049] The sample rack recovery and propulsion mechanism pushes the sample rack on the sample rack buffer mechanism into the recovery channel;

[0050] The sample rack in the recovery channel is pushed to the recovery guide groove by the horizontal pushing mechanism.

[0051] The present invention distributes and injects emergency sample racks and ordinary sample racks through different output channels. The emergency sample rack does not occupy the sample rack output channel used for injecting ordinary sample racks, which facilitates the sequential allocation of the emergency sample rack and the ordinary sample rack without affecting each other, thereby improving the allocation efficiency.

[0052] The present invention addresses the need for high-volume sample retesting through a sample rack caching mechanism, reducing the need for cuvette retesting while also eliminating the need for internal instrument cache slots, reducing instrument size, and improving operating speed. The present invention automatically delivers sample racks containing sample tubes to a sample aspiration station for aspiration upon user request. Upon completion of testing, the tested samples are transported to a sample rack recovery platform for user retrieval. It also implements functions such as emergency priority and retest caching.

[0053] The emergency channel of the present invention is set up. When the user places the sample rack in the channel and clicks the emergency option on the instrument interface, the track will give priority to pushing the channel sample rack into the instrument and giving priority to absorbing the emergency sample; the sample rack cache mechanism of the present invention can temporarily store multiple groups of sample racks inside the instrument. After the test is completed, if the instrument receives an instruction to retest a certain sample, the track will automatically transport the sample on the sample rack to the absorption position for re-absorption and testing. If retesting is required multiple times, the sample rack will be automatically pushed out after the last retest is completed.

[0054] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
