CN-115803636-B - Sample conveying device and sample conveying carrier

Abstract

The sample carrier (100) is provided with two or more holding parts (101) for supporting sample containers (150) with different diameters from different directions, and a conveying surface (201) for sliding the sample carrier (100), wherein the sample carrier (100) is provided with a direction adjustment part for adjusting the travelling direction of the sample carrier (100) when the sample carrier slides on the surface of the conveying surface (201) so that the direction of one holding part (101) of the two or more holding parts (101) holding the sample container (150) is the direction opposite to the travelling direction of the sample carrier (100). Thus, a specimen transport apparatus and a specimen transport carrier are provided which can suppress the shaking of a specimen compared with the prior art without restricting the transport path during electromagnetic transport.

Description

Sample conveying device and sample conveying carrier Technical Field The present invention relates to a specimen transport apparatus and a specimen transport carrier for transporting a specimen container in a specimen inspection automation system. Background In order to prevent the hand from wearing the grip surface of the hand when the hand holds the bucket on which the sample container is mounted, patent document 1 describes that the plurality of finger portions provided on the hand include a branch portion extending downward and a claw portion bent from the lower end portion of the branch portion toward the center axis of the hand, the bucket includes a protruding rod including an umbrella portion having a shaft and a flange portion protruding in a horizontal direction from a side surface of the shaft, and a slider vertically slidable along the outer periphery of the side surface of the shaft at a position lower than the umbrella portion, and the plurality of finger portions are lifted together with the slider in a state of gripping the slider, and the claw portion is hooked on the flange portion during this process. Prior art literature Patent literature Patent document 1 Japanese patent laid-open publication 2016-203309 Disclosure of Invention Problems to be solved by the invention In recent years, in a specimen examination for diagnosis in the medical field, effort and speed of the examination using an automated device have been advanced. Therefore, in the sample inspection automation system, the pretreatment device, the automatic analysis device, and the post-treatment device are connected by the sample transport device, and the automation of the operation related to the analysis treatment of blood is advanced. In such an automated system, a specimen carrier capable of mounting a specimen container containing one specimen is used. As an example of this, a method is known in which a plurality of electromagnets fixed below a transport surface are arranged to generate a magnetic field, and the magnets in a sample carrier are attracted and repelled to slide on the transport surface. By this transport method, the transport of the specimen is realized not in one dimension but in two dimensions. Here, if the specimen is shaken, there is a possibility that the analysis result is affected, and therefore it is important to suppress the liquid shake of the specimen. Therefore, it is preferable to convey the sample container so that the sample container itself does not shake. However, since specimen containers having different diameters are provided on the specimen carrier, it is difficult to control a minute force by the conveyance of the specimen carrier due to the attraction/repulsion of the electromagnet, and thus it is difficult to suppress the shake of the specimen container. Patent document 1 describes that the direction of the specimen carrier is corrected by the side surface of the specimen carrier in the one-dimensional belt conveying system. However, in such a technique, if the sample carrier is to be approached from the side during the two-dimensional sample transport, various problems occur such as a limitation in the transport path and a long transport time. The invention provides a sample conveying device and a carrier for conveying a sample, which do not limit a conveying path in electromagnetic conveying and can restrain shaking of the sample compared with the prior art. Means for solving the problems The present invention includes a plurality of means for solving the above-mentioned problems, and as an example thereof, is characterized by comprising a carrier having 2 or more holding portions for supporting specimen containers having different diameters from different directions, and a conveying surface on which the carrier slides, wherein the carrier has a direction adjustment portion for adjusting a traveling direction of the carrier when the carrier slides on the surface of the conveying surface so that a direction in which 1 of the 2 or more holding portions holds the specimen container becomes an opposite direction to the traveling direction of the carrier. Effects of the invention According to the present invention, in electromagnetic conveyance, the conveyance path is not limited, and the shake of the sample can be suppressed as compared with the conventional one. Other problems, configurations and effects than those described above will become apparent from the following description of examples.
