Description

Automatic dry chemical analyzer test strip dispensing device

[0001] The present invention relates to an automatic dry chemical analyzer, and more particularly to a fully automatic dry chemical analyzer test strip dispensing device.

Background technique

[0002] At present, there are two main types of automatic paper separation and sample loading methods for automatic dry chemical analyzers:

1) Automatic paper separation structure The test paper is placed on the side of the single reaction paper, and sent to the sample loading position, and each sample test paper is sampled by the sample needle and then sent to the instrument detection position for detection. The shortcomings of this method are mainly: a. It is difficult for the paper separation mechanism to ensure that all the test strips that are sent out are test paper faces up, and all are sent to the sample or detection position without bias. Therefore, the sample misdetection and the test paper waste phenomenon sometimes occur; b. Even if the test paper is normally sent to the sample loading position, it is difficult to ensure that each test paper block can be sampled and cause a certain Detection of missing items;

2) After the automatic paper separation, the test paper is immersed in the sample by the robot, and then the test paper impregnated with the sample is sent to the instrument detection position for detection.
