Automatic oil dripping mechanism for bone marrow smear scanner and working method of automatic oil dripping mechanism

Abstract

The automatic oil dripping mechanism comprises a component base, a component mounting plate and an oil dripping assembly, the component mounting plate and the oil dripping assembly are arranged on the component base, the oil dripping assembly comprises an oil storage bottle, a first oil pipe, a high-pressure valve, an injection pump, a second oil pipe, a third oil pipe, an oil dripping opening, an oil pipe pressing block and an oil drop induction sensor, the oil tank is used for storing oil for dripping oil; the oil pipe I is connected with the oil storage bottle and the high-pressure valve; the high-pressure valve is used for switching the oil transmission direction and distributing the oil; the injection pump is used for stably conveying the oil liquid and sucking and storing the oil liquid; the second oil pipe is used for connecting the injection pump and the high-pressure valve; according to the oil dripping mechanism, whole-course automatic oil dripping operation can be achieved, manpower and time are saved, the oil dripping process of the oil dripping mechanism can be seen from beginning to end, the operation process of oil drops can be visually observed, and problems can be found in time.

Description

technical field [0001] The invention relates to the field of bone marrow smear scanning equipment, in particular to an automatic oil dripping mechanism for a bone marrow smear scanner and a working method thereof. Background technique [0002] In the existing bone marrow cell image acquisition, an optical microscope is usually used. When using a low-power microscope 40X to a high-power microscope 100X, in order to remove the influence of the air refractive index on the image acquisition information, it is necessary to perform oil dripping on the bone marrow smear. The bone marrow smear can be better observed under the high-power microscope 100X, and the inconsistency of artificial oil dripping will lead to different oil dripping results, which is labor-intensive and time-consuming. Therefore, it is very important to design an automatic oil dripping device for bone marrow smear scanning. necessary. [0003] The invention patent with the patent application number 201910296980...

Problems solved by technology

[0002] When collecting images of bone marrow cells, optical microscopes are usually used. When switching from a low-magnification microscope 40X to a high-power microscope 100X, in order to remove the influence of the air refractive index on the image acquisition information, it is necessary to perform a dripping operation on the bone marrow smear, so that It is better to observe the bone marrow smear under a high-power microscope 100X, and the inconsistency of artificial oil dripping will lead to differences in the results of dripping oil, and it is labor-intensive and time-consuming. Therefore, it is very important to design an automatic oil dripping device for bone marrow smear scanning. necessary

[0003] The invention patent with the patent application number 201910296980.7 discloses an automatic oil dripping device for the objective lens changer on an optical microscope. The oil dripping device is positioned accurately and can control the amount of oil dripping, but the oil dripping process of the device is invisible , the process is not easy to observe, such as air bubbles in the oil pipe or oil leakage and other problems are not conducive to timely detection and solution
