[0004] BACKGROUND

[0005] In a conventional analytical laboratory, biological samples are collected, labelled, pretreated using, for example, a centrifuge and subsequently sorted while preparing for an analytical detection. Typically, the sample preparation may be performed manually by a medical technical assistant. Subsequently, the prepared sample may be loaded into or unloaded from the analyzing device manually and transported between the analyzing device and an sample handling table by the medical technical assistant. A modem automated analysis laboratory equipped is highly desired to be developed with the automation of the pre-detection and post detection procedures.

[0006] SUMMARY

[0007] It may be seen as an objective of the invention to provide an automated analyzing system with improved sample loading and unloading procedures.

[0008] The objective is achieved by the subject matter of the independent claims. The dependent claims, the following description and the drawings show embodiments of the invention.

[0009] According to a first aspect of the present, an unloading assembly is provided for a laboratory automation system. The unloading assembly comprises a removal insert element that comprises a bearing surface and a removal driving element. The removal driving element is configured to drive the sample tube rack to move towards a removal position, at which the bearing surface of the removal insert element is in contact with the sample tube rack. The removal insert element is configured to be arranged inside a first inner volume of the sample processing and / or analyzing system and allow the sample tube rack being removed from the sample processing and / or analyzing system at the removal position.

[0010] The unloading assembly may further comprise an unloading tray, on which the removal insert element and the removal driving element may be arranged.

[0011] The removal insert element may comprise a bearing element, which comprise the bearing surface facing the sample tube rack to be removed. At the removal position, the removal insert element may be configured to exert a resistance force against the sample tube rack at the bearing surface. In other words, the removal insert element may be configured to stop the moving of the sample tube rack driven by the removal driving element, so that the sample tube rack may be removed from the unloading assembly and from the sample processing and / or analyzing system, for example, by means of a robot arm.

[0012] In this way, the unloading procedure for the sample detection in the sample processing and / or analyzing system may be automated, without a manual loading by a user or a technical assistant. Advantageously, the automated unloading assembly may allow an efficient and economic sample analysis or detection even for a small or medium-sized hospital, for example, having up to 350 beds in the hospital, without being affected by the shortage of skilled personal.

[0013] According to an embodiment, the sample tube rack may be a single sample tube rack comprising at least one rack opening for accommodating at least one sample tube.

[0019] According to another embodiment, the removal driving element may be arranged at the same side of the sample tube rack as the removal insert element and configured to pull the sample tube rack and the removal insert element towards the removal position. For example, the removal driving element may be a suction element that may be arranged directly on the removal insert element to pull the sample tube rack for the removal of the sample tube rack. The removal driving element may be integrated at the bearing surface of the removal insert element. In this way, a separately arranged driving element may not be provided in the sample processing and / or analyzing system.

For example, when the position of the removal insert element may be detected to be at the removal position by means of the first sensor, the sample tube rack may be removed from the sample processing and / or analyzing system, for example, by means of a robot arm.

[0037] For example, when the presence of the sample tube rack may be detected at the loading position by means of the second sensor, the loading assembly may be configured to actuate the loading driving element to move towards the sample tube rack and drive the sample tube rack to slide along the guide element of the loading tray.

[0038] The first sensor and the second sensor may advantageously result in an automated sample processing and / or analyzing system.

[0073] DETAILED DESCRIPTION OF EMBODIMENTS

[0074] Fig. 1 to Fig. 4 show, respectively, schematically an example of an unloading assembly 100 for automatically unloading a sample tube rack from a sample processing and / or analyzing system 500 of a laboratory automation system 10 (as shown in Fig. 7 and Fig. 8). The unloading assembly 100 comprises a removal insert element 110 and a removal driving element 120.

[0075] The unloading assembly 100 may comprise an unloading tray, on which the removal insert element 110 and the removal driving element 120 may be arranged. The unloading assembly, in particular the removal insert element 110, may be arranged inside a first inner volume 510 of the sample processing and / or analyzing system 500.

[0076] The removal driving element 120 is arranged inside the first inner volume 510 of the sample processing and / or analyzing system 500 and may be configured to drive the sample tube rack 50 to move from a detection ending position 320 in the sample processing and / or analyzing system 500 towards a removal position, at which the bearing surface of the removal insert element 110 is in contact with the sample tube rack.

[0077] The removal insert element 110 comprises a bearing element 115 which comprises a bearing surface, which faces a sample rube rack loaded into the sample processing and / or analyzing system 500. The removal insert element 110 is configured to allow the sample tube rack 50 being removed from the sample processing and / or analyzing system 500 at the removal position. For example, the removal insert element 110 may be configured to exert a resistance force against the sample tube rack 50 at the bearing surface and to stop the moving of the sample tube rack 50 at the removal position.

[0078] Optionally, the removal insert element 110 may be fixed inside the first inner volume 510, so that the sample tube rack 50 may be driven to move towards the removal insert element 110, until the sample tube rack 50 comes into contact with the bearing surface at the removal position. Alternatively, the removal insert element 110 may be configured to be movable between a first position and a second position which may be the removal position, at which the sample tube rack 50 is removable from the sample processing and / or analyzing system 500. Accordingly, the removal insert element 110 may be configured to come into contact with the sample tube rack 50 at the first position, which may be between the detection ending position 320 and the removal position. Further, the removal driving element 120 may be configured to drive the sample tube rack 50 and the removal insert element 110 to move as a whole from the first position to the second removal position.

[0079] The removal insert element 110 may further comprise a protrusion 150, which may be configured to be driven for moving the removal insert element 110 from the second position to the first position, after the sample tube rack 50 is removed from the sample processing and / or analyzing system 500. As shown in Fig. 1 , the protrusion 150 may be designed to extend in parallel to the bearing surface of the bearing element 115. For example, the protrusion 150 may be designed to come into contact with a external robot arm 650 (shown in Fig. 3) at a surface facing away from the detection ending position 320, so that the removal insert element 110 may be driven from the removal position back to the first position, after the sample tube rack 50 is removed from the sample processing and / or analyzing system 500 by the robot arm 650. The unlading assembly 100 may be designed to arrange the removal insert element 110 at the first position, when the sample tube rack 50 is absent in the first inner volume 510.

[0080] The removal driving element 120 is arranged at an opposite side of the sample tube rack 50 to the removal insert element 110 and configured to push the sample tube rack 50 and the removal insert element 110 towards the removal position.

[0081] The sample tube rack 50 may be a single sample tube rack, which may comprise a plurality of rack openings, such as five rack openings as shown in Fig. 1 , for accommodating sample tubes. The removal insert element 110 may be configured to allow the single sample tube rack 50 being removed from the sample processing and / or analyzing system 500 at the removal position, since the removal driving element 120 may be configured to move freely towards the removal insert element 110 in the first inner volume 510 for pushing the single sample tube rack 50 against the removal insert element 110. The removal insert element 110 may be a three-dimensional printing insert element and designed to fit the first inner volume 510 of the sample processing and / or analyzing system.

[0082] Fig.1 and Fig. 2 show, respectively, that a loading assembly 200 is provided for automatically loading a sample tube rack 50 into a sample processing and / or analyzing system 500 of a laboratory automation system 10.

[0083] The loading assembly 200 comprises a loading tray 210, which comprises a guide element 215, and a loading driving element 220 as shown in Fig. 4 and Fig. 6, which is configured to exert a driving force on the sample tube rack 50 for loading the sample tube rack 50 for the sample processing and / or analyzing system 500, in particular, for drive the sample tube rack 50 to move from a loading position of the loading assembly 100, as shown in Fig. 5, to a detecting starting position 310 of a detection assembly 300 of the sample processing and / or analyzing system 500. The loading tray 210 may be configured to be arranged inside a second inner volume 520 of the sample processing and / or analyzing system 500 and to allow the loading driving element 220 to drive the sample tube rack 50 to slide along the guide element 215 from the loading position to the detection starting position 310 (shown in Fig. 2). Similar to the unloading assembly 100, the loading assembly 200 may allow the single sample tube rack 50 being arranged on the loading tray 210 and being driven to the detection starting position 310.

[0084] As shown in Fig. 2, Fig. 4, Fig. 5, and Fig. 6, the guide element 215 of the loading tray 210 may be designed to comprise a rail structure which extends along the loading tray 210 and may be configured to allow the sample tube rack 50 sliding along the rail. By means of a robot arm 650 as shown in Fig. 3, the sample tube rack 50 may be placed on the loading tray 210 of the loading assembly 200 in the second inner volume 520.

[0085] Fig. 4 shows further that the loading assembly 200 is connected to the detecting assembly 300 at the detection startin position 310, while the unloading assembly 100 is connected to the detecting assembly 300 at the detection ending position 320. The guide element 215 of the loading tray 210 is arranged perpendicular to the detecting path.

[0086] Alternatively or additionally, the loading assembly 200 may be designed as a fast track channel, which may be configured to allow the sample tube rack 50 moving from the loading tray to the detection starting position 310 continuously without altering the moving direction. The guide element 215 of the loading tray 210 is arranged laterally to the detecting path, allowing the sample tube rack 50 being driven to move from the guide element 215 to the detecting path continuously in a direction.

[0087] Fig. 5 shows further that the guide element 215 may comprise a securing unit 216, which may be configured to secure the sample tube rack 50 on the loading tray 210, when the sample tube rack 50 is arranged on the loading tray 210 at the loading position and / or slides along the guide element 215 towards the detection starting position 310. The guide element 215 may be designed to engage with a recess of the sample tube rack 50, which may be arranged at the bottom of the sample tube rack 50.

[0088] In Fig. 2, Fig. 4 and Fig. 6, the loading driving element 220 is arranged separately from the guide element 215 of the loading tray 210 and may thus be configured to push the sample tube rack 50 towards the detection starting position. Alternatively, the loading driving element 220 may be integrated in the guide element 215 of the loading tray 210 and configured to slide along the guide element 215 with the sample tube rack 50 towards the detection starting position 310, so that an external loading driving element is not necessary, resulting in a simplified and compact loading assembly 100.

[0089] Fig. 8 shows schematically an example of a laboratory automation system 10, which comprises multiple sample processing and analyzing systems 500 and a sample handling system 600.

[0090] The sample processing and analyzing system 500, which is shown in the previous Fig. 1 to Fig. 6, comprises the unloading assembly 100 in the first inner volume 510 with the removal insert element 110 and the removal driving element 120, the loading assembly 200 in the second inner volume 520 with the loading tray 210 having the guide element 215 and the loading driving element 220, and a detecting assembly 300 that may be configured to allow the sample tube rack 50 moving along the detecting path from the detection starting position 310 to the detection ending position 320 to perform the sample detection of the samples accommodating in the sample tube rack 50.

[0091] The sample to be detected may be, but not limited to, a biological sample such as a blood sample, a tissue biopsies sample, a saliva sample, a cerebrospinal fluid sample, a sputum sample or a bone marrow sample. For example, the sample processing and analyzing system 500 may be a blood sample analyzing system.

[0092] The sample handling system 600 comprises, for example, two robot arms 650 and may be configured to prepare at least one sample in at least one sample tube in the sample tube rack 50. In Fig. 8, one of the two robot arms 650 is arranged at a distance to the sample processing and / or analyzing system 500 and configured to transfer the sample tube rack 50 from the sample handling system 600 to the loading assembly 200 of the sample proceeding and / or analyzing system 500.

[0093] The sample processing and analyzing system 500 may further comprise a first sensor, which may be configured to detect a position of the removal insert element 110 of the unloading assembly 100 inside the first inner volume 510. When the position of the removal insert element 110 is detected at the removal position, the one of the robot arm 650 may be activated. As such, the at least one robot arm 650 may be configured to remove the sample tube rack 50 from the sample processing and / or analyzing system 500, when the position of the removal insert element 110 of the unloading assembly 100 is detected at a removal position.

[0094] Alternatively or additionally, the sample processing and analyzing system 500 may further comprise a second sensor,, which may be configured to a presence of the sample tube rack 50 at the loading position. The at least one robot arm 650 may be configured to drive the sample tube rack 50 from the loading position to the detection starting position 310 inside the second inner volume 520, when the presence of the sample tube rack 50 is detected at the loading position by means of the second sensor.
