Abstract
Description
Technical Field
[0001] The invention relates to the technical field of urine detection, and in particular to a centrifugal sediment type urine analysis device and a working method thereof. Background Art
[0002] Urinalysis is a routine test item in clinical medicine, which provides a basis for diagnosis. Urinalysis usually includes urine sediment analysis and urine drying analysis. When performing urine sediment analysis, it is necessary to perform sedimentation operation on the sample liquid that is sampled and dripped on the slide, or to sample the sample liquid after the sedimentation operation and drip it on the slide, and then transfer the slide with the sample liquid to a microscope to check the formed components.
[0003] At present, the sedimentation methods include natural sedimentation and centrifugal sedimentation. Natural sedimentation requires sufficient time for the formed components in the sample liquid to settle down, but this prolongs the overall detection time and the detection efficiency is relatively low. When using a centrifuge for centrifugal sedimentation, the rotating shaft of the centrifuge is usually placed vertically, and the rotating parts of the centrifuge drive the sample liquid to rotate. The sample liquid is subjected to the centrifugal force in the horizontal direction and quickly precipitates. Obviously, when the sample liquid is centrifuged, it needs to be placed in a sealed test tube. If the sampling and dropping operation is performed first and then the sedimentation operation is performed, the sample liquid will be thrown off the slide, affecting the results of the subsequent microscopic examination; if the sedimentation operation is performed first and then the sampling and dropping operation is performed, the staff needs to manually transfer the test tube containing the sample liquid, which is not convenient enough.
[0004] In addition, when existing analytical equipment is in use, sampling, dripping and transfer operations are all performed by staff, with a high degree of manual intervention, which seriously wastes manpower. Moreover, due to the low manual dexterity, the detection time is also relatively long, resulting in low detection efficiency. Summary of the invention
[0005] One advantage of the present invention is that it provides a centrifugal sediment type urine analysis device and a working method thereof. The present invention first performs a sampling and dropping operation and then performs a sedimentation operation. When the sample liquid on the slide is centrifuged, the sample liquid on the slide is subjected to a vertical centrifugal force, so that the sample liquid is accelerated to settle while always remaining on the slide. Compared with the prior art, the situation in which the sample liquid is thrown off the slide is effectively avoided, ensuring that the sample liquid can be smoothly sedimented on the slide.
[0006] One advantage of the present invention is that it provides a centrifugal sediment type urine analysis device and a working method thereof. The present invention can take samples and drop the sample liquid on a slide, and push the slide to move to multiple locations to perform centrifugal sediment operations and microscopic photography and collection operations on the sample liquid on the slide in turn. In this process, no human intervention is required, and each operation is carried out in an orderly manner. Compared with the existing technology, the detection efficiency is higher.

The centrifugal sediment member 62 forms a slot 6201 at a position deviating from its rotation center, and the size of the slot 6201 is adapted to the slide, and the push-in port 6102 and the push-out port 6103 both correspond to the rotation path of the slot 6201 when the centrifugal sediment member 62 rotates. When the two notches of the slot 6201 correspond to the push-in port 6102 and the push-out port 6103 respectively, the slide in the guide groove 1201 can be pushed away from the bottom of the sampling member 211 by the pushing member 4211 and enter the slot 6201 through the push-in port 6102, so as to increase the convenience of the slide transfer.
