Sample pretreatment system that supports multisystem configuration
View Patent ↗A host system recognizes a sample pretreatment system at which a primary sample has first arrived and records the information, if multiple containers containing the primary sample are input. Upon issuing an analysis request to the sample pretreatment system, the host system determines whether the primary sample (sample bearing the same barcode for sample identification) is input to a system different from the system to which the sample was input for the first time and, if that is the case, then determines that “the sample is input to the wrong system” and issues a “do-nothing request” (request to do nothing) so that an aliquoting operation will not be performed. Given the “do-nothing request” from the host system, the sample pretreatment system does not prepare any aliquot sample and places the input sample onto a tray in a predetermined position.
1. A control method used in a system including a plurality of sample pretreatment systems, the control method comprising:
when a sample is input to a first sample pretreatment system of the sample pretreatment systems, determining whether a same sample was previously input to a second sample pretreatment system of the sample pretreatment systems;
when the same sample was previously input to the second sample pretreatment system, recovering the sample from the first sample pretreatment system without aliquoting the sample in the first sample pretreatment system; and
displaying an alarm that the same sample was previously input to the second sample pretreatment system,
wherein the same sample is determined to have been previously input to the second sample pretreatment system when the second sample pretreatment system reads and transmits sample information of the same sample before the first sample pretreatment system reads and transmits sample information of the sample.
2. The control method according to claim 1 , further comprising:
when the same sample was not previously input to the second sample pretreatment system, aliquoting the same sample in the first sample pretreatment system.
3. The control method according to claim 1 , further comprising:
when the same sample was previously input to the second sample pretreatment system, aliquoting the same sample in the second sample pretreatment system.
4. The control method according to claim 2 , wherein the same sample is input to the first sample pretreatment system and the second sample pretreatment system in different containers.
5. The control method according to claim 1 , wherein the same sample from a second container in the second sample pretreatment system is aliquoted, and
the sample in a first container in the first sample pretreatment system is recovered without aliquoting the sample from the first container.
6. A system for pretreating a plurality of sample containers, comprising:
a host; and
a plurality of sample pretreatment systems connected to the host, and each of the sample pretreatment systems includes:
input means for receiving one or more of the sample containers,
reading means for reading sample information from the sample containers received by the input means, and
aliquoting means for aliquoting samples from the sample containers read by the reading means,
wherein the host system is programmed to:
when a sample in a first sample container of the sample containers is input to a first sample pretreatment system of the sample pretreatment systems, determine whether a same sample in a second sample container of the sample containers was previously input to a second sample pretreatment system of the sample pretreatment systems,
when the same sample in the second sample container was previously input to the second sample pretreatment system, recover the sample in the first sample container from the first sample pretreatment system without aliquoting the sample in the first sample container in the first sample pretreatment system; and
display an alarm that the same sample in the second sample container was previously input to the second sample pretreatment system,
wherein the same sample in the second sample container is determined to have been previously input to the second sample pretreatment system when the second sample pretreatment system is determined to have transmitted the sample information read from the second sample container by the reading means thereof to the host system before the first sample pretreatment system has transmitted the sample information read from the first sample container by the reading means thereof to the host system.
7. The system according to claim 6 , wherein the host system is further programmed to:
when the same sample in the second sample container was not previously input to the second sample pretreatment system, instruct the first sample pretreatment system to aliquot the same sample in the first sample container in the first sample pretreatment system.
8. The sample pretreatment system according to claim 6 , wherein the host system is further programmed to:
when the same sample was previously input to the second sample pretreatment system, instruct the second sample pretreatment system to aliquot the same sample in the second sample container.
