Description

Technical Field

[0001] The utility model relates to the field of automatic sample transmission, and specifically relates to a sample transmission system. Background Art

[0002] In recent years, in order to improve the detection speed of patient samples and reduce the personnel cost, medical institutions usually install an automatic laboratory sample transmission system, which is divided into a sample pretreatment system, a sample transmission system, and a sample detection system. The pretreatment system generally includes an in / out sample module, a centrifugation module, a cap opening module, a buffer module, etc.

[0003] The existing automatic laboratory sample transmission system can automatically process hundreds or even thousands of patient samples in a day. The pretreatment system can automatically identify the patient samples, then classify them according to the test items of the patient samples, and transmit the patient samples that need to be centrifuged / uncapped to the centrifugation module and the cap opening module for sample centrifugation and cap opening treatment, and then transmit the processed patient samples to the sample transmission system and the sample detection system. For the samples that do not need to be processed, the patient samples can be directly transmitted to the sample transmission system and the sample detection system.

[0004] However, since the existing automatic laboratory sample transmission system uses a single-layer track for transmission, the sample holders carrying patient samples and the empty sample holders are both transmitted on the same track. Therefore, the track transmission requires multiple transmission intersection position judgments and transmissions, its structure is relatively complex, and it is easy to cause a decrease in detection efficiency due to blockage.

[0166] It should be noted that the third stepping motor 3-32-1 drives the first pulley 3-32-5 to rotate, which can drive the synchronous belt 3-32-7 to rotate. Since the cup holder fixing plate 3-32-8 is fixed to the synchronous belt 3-32-7, the synchronous belt 3-32-7 can drive the cup holder fixing plate 3-32-8 to move up and down along the third linear guide rail 3-32-9.

[0167] By setting the fifth optocoupler 3-32-2 and the sixth optocoupler 3-32-3, it can effectively detect whether the cup holder fixing plate 3-32-8 moves to the target position, and then facilitate the control of the start, stop, forward and reverse rotation of the third stepping motor 3-32-1 to realize the up and down movement of the sample holder driven by the cup holder fixing plate 3-32-8.

[0184] It should be noted that through the centrifugal conveying assembly 4 disclosed above, when the sample needs to be centrifuged, the sample holder carrying the sample can be conveyed to the first centrifugal support rail 4-1 by the first centrifugal turntable 4-5. At this time, the sample to be centrifuged can be removed from the sample holder for centrifugation. The sample holder from which the sample has been removed is then conveyed to the third lifting mechanism 4-9 through the first centrifugal support rail 4-1, and then the third lifting mechanism 4-9 conveys the empty sample holder to the third centrifugal support rail 4-3. The third centrifugal support rail 4-3 then conveys the empty sample holder to the lower conveyor belt 2 through the third centrifugal turntable 4-7. After the sample centrifugation is completed, when the sample needs to be placed on the sample holder, the fourth centrifugal turntable 4-8 conveys the empty sample holder conveyed by the lower conveyor belt 2 to the fourth centrifugal support rail 4-4, and then the fourth centrifugal support rail 4-4 conveys the empty sample holder to the second centrifugal support rail 4-2 through the fourth lifting mechanism 4-10. At this time, the centrifuged sample can be placed on the empty sample holder, and then the sample holder carrying the centrifuged sample is conveyed to the upper conveyor track through the second centrifugal turntable 4-6 through the second centrifugal support rail 4-2 for subsequent processing.

[0188] It should be noted that since multiple samples can be centrifuged during centrifugation, the fifth centrifuge turntable 4-11 and the sixth centrifuge turntable 4-12 are arranged on the first centrifuge rail 4-1 at a first preset interval, and the fifth centrifuge turntable 4-11 is located upstream of the sixth centrifuge turntable 4-12. The seventh centrifuge turntable 4-13 and the eighth centrifuge turntable 4-14 are arranged on the second centrifuge rail 4-2 at a second preset interval, and the seventh centrifuge turntable 4-13 is located downstream of the eighth centrifuge turntable 4-14. Then, after the sample to be centrifuged enters between the fifth centrifuge turntable 4-11 and the sixth centrifuge turntable 4-12, it waits for the staff to remove the sample to be centrifuged from the sample holder, preventing the sample holder and the sample to be centrifuged from flowing into the lower conveyor belt 2 together. Moreover, the sample to be centrifuged can be cached between the fifth centrifuge turntable 4-11 and the sixth centrifuge turntable 4-12 until the number of samples to be centrifuged reaches a certain amount, and then the samples to be centrifuged are uniformly removed for centrifugation processing.

[0189] The seventh centrifuge turntable 4-13 and the eighth centrifuge turntable 4-14 are arranged on the second centrifuge rail 4-2 at a second preset interval. Then, when the empty sample holder enters between the seventh centrifuge turntable 4-13 and the eighth centrifuge turntable 4-14, multiple empty sample holders can be cached, and caching multiple empty sample holders enables the staff to place multiple centrifuged samples at one time.

The first end of the lid-opening support rail 51 is connected to the first lid-opening turntable 52, and the second end is connected to the upper conveyor belt 1. The sample holder carrying the sample to be lid-opened is conveyed to the lid-opening support rail 51 or the sample holder that does not need to be lid-opened is conveyed to its downstream through the first lid-opening turntable 52. And the sample holder carrying the sample to be lid-opened is conveyed to the lid-opening module through the lid-opening support rail 51 for lid-opening, and the sample holder carrying the sample after lid-opening is conveyed to the upper conveyor belt 1. When the sample needs to be lid-opened, the sample holder carrying the sample conveyed by the upper conveyor belt 1 can be conveyed to the lid-opening support rail 51 through the first lid-opening turntable 52, and then conveyed to the lid-opening module by the lid-opening support rail 51 to open the sample on the sample holder, and the sample holder carrying the sample after lid-opening is conveyed to the upper conveyor belt 1 for subsequent processing.

[0195] Furthermore, the lid-opening conveying assembly 5 further includes: a second lid-opening turntable 53 arranged on the lid-opening support rail 51.

[0196] It should be noted that by arranging the second lid-opening turntable 53 on the lid-opening support rail 51, when the lid-opening module cannot open the sample in time, the second lid-opening turntable 53 can be used to restrict the sample holder carrying the unopened sample from entering the upper conveyor belt 1, thereby effectively preventing the sample holder carrying the unopened sample from flowing into the next link.
