Description

Technical Field

[0001] The present invention relates to the technical field of biological instruments, and in particular to a slide pushing device. Background Art

[0002] In the biological and medical fields, glass slides are needed for sample preparation. Traditional sample preparation generally involves manually extracting glass slides and manually making smears of samples. However, this method requires high operator skills and is inefficient, and is not suitable for the preparation of large quantities of samples. There are many devices on the market that can replace manual slide preparation to achieve batch sample preparation, but if the slides in the slide box are manually taken out and then inserted into the slide preparation device, the time and labor costs are relatively high. In order to improve the efficiency of batch production and realize the full automation of the production process, a device that can automatically take slides and push them into the slide preparation device is particularly important.

[0003] Patent document CN209222169U discloses a push-pull type slide storage device, comprising a storage box with an opening on one side and one or more slide placement bins; the push-pull slide placement bin allows the slide placement bin to enter or pull out of the storage box along the opening of the storage box; a movable door is provided at the opening of the storage box; the movable door and the side wall of the storage box are provided with a mutually cooperating anti-drop structure. This patent document can classify and place slides for easy sorting, without being directly exposed to the outside, and has a large storage capacity and is easy to access and place, but it only has a storage function without a push function, and needs to be manually accessed, which is too inefficient for batch preparation of samples.

[0053] An embodiment of the application of the present invention is as follows Fig.10As shown, the present invention is applied to the insert of a sedimentation tray 7220, and the sedimentation tray 7220 is used to prepare biological samples. A plurality of sedimentation cups are circumferentially arranged inside the sedimentation tray 7220, and a glass slide placement position is provided under each sedimentation cup for sample preparation. The sedimentation cup can rotate around the central axis of the sedimentation tray 7220, and one or more glass slide insertion ports 7221 are circumferentially arranged on the sedimentation tray 7220. When there is one glass slide insertion port 7221, the position of the glass slide insertion port 7221 is fixed and does not rotate. When there are multiple glass slide insertion ports 7221, the glass slide insertion ports 7221 correspond one-to-one to the sedimentation cups and rotate with the sedimentation cups.

After a glass slide is pushed out, the next glass slide automatically falls to the push position corresponding to the glass slide outlet 7203 due to gravity. At the same time, the sedimentation tray 7220 rotates one grid, and then a glass slide is pushed out from the glass slide outlet 7203 by the push piece 7216 and pushed from the glass slide insertion port 7221 to the glass slide placement position corresponding to the sedimentation cup in the sedimentation tray 7220.
