Technical Field

[0001] The present invention relates to the technical field of medical diagnosis, and in particular to a pipeline system and a sample scheduling method. Background Art

[0002] As the level of medical testing improves, the number of samples tested in hospitals is getting larger and larger. Traditional single testing instruments cannot meet the needs of medical institutions. The assembly line system composed of various medical analysis instruments connected online is becoming more and more popular.

[0003] A large amount of sample container loading is required during the operation of the assembly line system. The existing sample container sampling requires manual sampling, and the matching of the test items and the sample containers is also completed by manual operation. When the sample containers are loaded, the sample containers are manually placed in the sample rack, and the sample rack carries the sample containers on the assembly line system. The above sampling and injection operations are likely to cause the test items to not match the sample containers, resulting in the inability of the assembly line system to perform normal testing. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention discloses a pipeline system and a sample scheduling method to solve the problem in the existing pipeline system that the sample cannot be detected due to the mismatch between the detection items and the sample containers.

[0006] Furthermore, the first identification device includes: An optical coupling component is used to detect whether it contacts the sample container below during its descent; The driving mechanism is used to drive the optical coupling component to move up and down.

[0007] Furthermore, when the optical coupling component descends to contact the sample container, the optical coupling component sends a trigger signal to the controller, and the controller is configured to: determine the descending height of the driving mechanism according to the trigger signal; and determine the type of the sample container according to the descending height.

[0008] Furthermore, the optical coupler assembly includes a mounting bracket, an optical coupler and a signal reflecting plate; the optical coupler and the signal reflecting plate are both mounted on the mounting bracket; a conveying channel for the sample container is formed between the optical coupler and the signal reflecting plate; the mounting bracket is connected to a driving mechanism, and the driving mechanism is used to drive the mounting bracket to move up and down, thereby driving the optical coupler and the signal reflecting plate to move up and down.

[0009] Furthermore, it also includes: The second identification device is used to identify the project information of the sample container and the sample rack information of the sample rack where the sample container is located.

[0010] Furthermore, after the second identification device identifies the project information and the sample rack information, the controller is configured to: determine the sample analyzers corresponding to all the detection items on the sample rack according to the project information and the sample rack information, and determine whether the sample analyzer is compatible with the types of all the sample tubes on the sample rack; if they are compatible, the sample container is allocated to the corresponding sample analyzer, otherwise the sample container is recycled.

[0015] Figure 1 is a structural diagram of a first identification device; Figure 2 The flowchart of the sample scheduling method is shown in FIG.

[0016] Figure numerals: 1-mounting bracket; 2-optical coupler; 3-signal reflection plate. Implementation

[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. 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 creative work are within the scope of protection of the present invention.

[0018] An embodiment of the present invention provides an assembly line system, comprising a plurality of sample analyzers, a first identification device and a controller; the sample analyzer is used to perform at least one detection item on the sample; the first identification device is used to detect whether it contacts the sample container below during its descent; the controller is used to control the operation of the sample analyzer and the first identification device, and to determine whether the first identification device contacts the sample container based on feedback information from the first identification device, and when it is determined that the first identification device contacts the sample container, obtain the descent height of the first identification device, determine the type of the sample container based on the descent height, and determine whether the type of the sample container matches the item information, and allocate the sample container to the corresponding sample analyzer or recycle it based on the matching result.

[0019] The pipeline system provided by the present invention detects the type of sample container before scheduling the sample container and determines whether the type of the sample container matches the project information, which can prevent mismatched sample containers from being assigned to the sample analyzer, resulting in the sample analyzer being unable to detect. The present invention improves the detection efficiency and speed of the pipeline system.

[0020] Furthermore, the first identification device includes an optical coupling component and a driving mechanism. The driving mechanism is connected to the optical coupling component and is used to drive the optical coupling component to move up and down. The optical coupling component is used to detect whether it contacts the sample container below during its descent. When the optical coupling component descends to contact the sample container, the optical coupling component sends a trigger signal to the controller.

[0021] As an embodiment, the controller is configured to: control the driving mechanism to descend until the optical coupling component contacts the sample container and sends a trigger signal, determine the descent height of the driving mechanism according to the trigger signal of the optical coupling component; and determine the type of the sample container according to the descent height.

[0022] In this embodiment, when the optical coupling component contacts the sample container, the controller immediately determines the descending height of the driving mechanism according to the trigger signal, and determines the type of the sample container according to the descending height of the driving mechanism. Not only is the determination method simple and accurate, but the process operation is also simple.

[0023] Furthermore, the type of sample container includes information on height and presence or absence of a cap. Specifically, in the present embodiment, the sample containers are divided into four types according to the height and presence or absence of a cap, including a tall sample container with a cap, a tall sample container without a cap, a low sample container with a cap, and a low sample container without a cap. The heights of the above four types of sample containers are different. Therefore, when the first identification device identifies, the descending height of the driving mechanism is different, and the type of the sample container can be judged based on the descending height of the driving mechanism.

[0024] Furthermore, the controller pre-stores a relational database of the descent height of the drive mechanism and the type of sample container, that is, for each type of sample container, the corresponding sample container type can be found in the relational database according to the descent height, which helps to simplify the determination of the type of sample container.

[0025] Furthermore, the controller pre-stores a database of relationships between project information and sample container types, that is, for each type of project information, the corresponding sample container type can be found in the relationship database; the controller is configured to: obtain the pre-stored sample container type according to the project information, compare the pre-stored sample container type with the actually determined sample container type, and determine whether the project information matches the sample container type according to the comparison result.

[0026] Further, such as Figure 1 As shown, the optical coupler assembly includes a mounting bracket 1, an optical coupler 2 and a signal reflecting plate 3, the optical coupler 2 and the signal reflecting plate 3 are both mounted on the mounting bracket 1, and a conveying channel for the sample container is formed between the optical coupler 2 and the signal reflecting plate 3; the mounting bracket 1 is connected to a driving mechanism, and the driving mechanism can drive the mounting bracket to move up and down, thereby driving the optical coupler 2 and the signal reflecting plate 3 to move up and down; when the sample container moves to the bottom of the optical coupler assembly, the controller controls the driving mechanism to carry the optical coupler assembly downward, and when the optical coupler 2 and the signal reflecting plate 3 sense the presence of the sample container during the movement, the optical coupler assembly sends a trigger signal to the controller, and the controller determines the descending height of the driving mechanism.

[0027] Furthermore, it also includes a second identification device, which is used to identify the project information of the sample container and the sample rack information of the sample rack where the sample container is located. The sample container and the sample are provided with an identification code. The second identification device identifies the identification code on the sample container and the sample rack and feeds it back to the controller.

[0028] Furthermore, the controller is configured to: determine the sample analyzers corresponding to all the test items on the sample rack according to the project information and the sample rack information, and determine whether the sample analyzer is compatible with the types of all the sample tubes on the sample rack; if compatible, the sample container is allocated to the corresponding sample analyzer, otherwise the sample container is recycled. By determining whether the sample analyzer is compatible with all the sample tubes on the sample rack, it is possible to prevent one or more sample containers at different heights on the same sample rack from not matching the sample analyzer.

[0029] Furthermore, the controller pre-stores a relational database of sample analyzers and sample tube types, that is, each type of sample analyzer can find the corresponding sample tube type in the relational database, and the controller is configured to: determine the sample analyzer used for all sample containers on the sample rack based on the sample rack information and project information, and determine whether the sample analyzer is compatible with all sample containers on the sample rack based on the relational database. This is helpful in determining whether the sample analyzer matches a sample container of the wrong height. For example, according to the identification code, it is confirmed that there are both high sample containers with tube caps and low sample containers without tube caps on a sample rack. When the sample analyzer is not compatible with the above two types of sample containers, the controller cannot allocate the sample containers on the sample rack, and the sample containers that cannot be sampled need to be left behind and re-identified and allocated.

[0030] Furthermore, the second identification device is a code scanning device, and the identification code is an identification code such as a barcode or a QR code.

[0031] Furthermore, it also includes a track system, which includes a loading area, a conveying track and an unloading area; the first identification device is arranged in the loading area; the sample analyzer is arranged on one side of the conveying track; the conveying track is used to distribute the sample containers in the loading area to the sample analyzer for detection or to the unloading area for recovery according to the scheduling instructions of the controller.

[0032] Furthermore, the multiple sample analyzers may be of the same type capable of detecting the same items, or may be a combination of different sample analyzers capable of detecting different items. The sample analyzers may be configured differently according to the needs of the hospital. Specifically, the sample analyzer provided in this embodiment may be a combination of any one or more of a hematology analyzer, a coagulation analyzer, and a chemiluminescence analyzer.

[0033] like Figure 2As shown, this embodiment also provides a sample scheduling method for a pipeline system. The sample scheduling method can be applied to a controller of the pipeline system for scheduling sample containers, and includes the following steps: Determining the type of the sample container according to the descending height of the first identification device; Determine whether the type of the sample container matches the project information; The sample container is assigned to the corresponding sample analyzer or recycled according to the matching results.

[0034] The method detects the type of sample container and determines whether the type of sample container matches the project information, thereby preventing mismatched sample containers from being assigned to a sample analyzer, causing the sample analyzer to be unable to detect, thereby improving detection efficiency and speed.

[0035] Further, determining whether the type of the sample container matches the project information includes: Acquire the type of the pre-stored sample container according to the project information; The type of the sample container is compared with the type of the pre-stored sample container to determine whether the project information matches the type of the sample container.

[0036] Furthermore, it also includes: Identify the project information of the sample container and the sample rack information of the sample rack where the sample container is located by a second identification device; Determine the sample analyzer corresponding to all the test items on the sample rack according to the project information and the sample rack information; Determine whether the sample analyzer is compatible with all sample tube types on the sample rack; If compatible, the sample container is assigned to the corresponding sample analyzer; otherwise, the sample container is recycled.

[0037] By determining whether the sample analyzer is compatible with all sample tubes of the sample rack, it is possible to prevent one or more sample containers at different heights on the same sample rack from being incompatible with the sample analyzer.

[0038] The above are merely embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of the claims of the present invention to be approved.
