Problems solved by technology

The first method can only be processed at normal temperature, and it is impossible to achieve good sealing. The solution evaporates into the room and diffuses in the air, affecting the health of operators.
The second method has several pipes and dozens of valves, if one leaks, the whole machine will not work
In addition, these two methods also have a potential danger. During the one-day or one-night processing process, it is difficult to ensure that there are always operators present. have irreversible serious consequences

specific Embodiment approach

[0008] In order to better understand the technical solution of the present invention, further description will be made below in conjunction with the accompanying drawings.

[0009] figure 1 It is a structural schematic diagram of the dehydrator device of the present invention.

[0010] As shown in the figure, several liquid storage tanks 4 are placed on the turntable 5 of the cell dehydrator. The liquid storage tanks 4 are connected to the airtight container 1 through flexible pipes 3 and switchable sealing joints 2. There is also a transmission arm 6 on the turntable 5, which can Drive liquid storage tank 4 to move up and down. There are treatment solutions 8 such as alcohol, acetone, xylene and liquid paraffin in the airtight container 1 , and the biological tissue 7 to be treated is immersed in these treatment solutions 8 , and an ultrasonic transducer 9 is installed in the airtight container 1 .

[0011] The present invention adopts a fully automatic airtight method to a...

Abstract

The present invention relates to a cell dehydrater and its dehydration method. It is characterized by that the biological tissue required for treatment is soaked in the treatment solutions of alcohol, acetone, dimethyl benzene and liquid paraffin, and is placed in the reverberation field produced by ultrasonic transducer, several liquid-storage tanks are placed on the rotating disk of the dehydrater, and are connected with closed container by means of flexible pipe and sealing joint. Said invention utilizes the rotating disk, conveying arm and changer-over sealing joint to implement the replacement of liquid-storage tank. It can automatically and quickly replace water content in cell by liquid paraffin, and can effectively shorten the treatment process of biological tissue of cell, and can raise its working reliability.

Description

Technical field: [0001] The invention relates to a cell dehydrator and a dehydration method thereof, in particular to a dehydrator capable of automatically and rapidly replacing intracellular water with paraffin and a dehydration method thereof, belonging to the technical field of biomedicine. Background technique: [0002] Due to the needs of microscopic observation, the slices of animal and plant tissues must be very thin, generally 3-5 microns, which requires removing the water in these tissues and replacing them with paraffin. The traditional method of this process is to soak three to five times with different concentrations of alcohol, each time for 1 to 2 hours, to separate out the water in the tissue, and then soak two times in an intermediate solution that has affinity with alcohol and paraffin. To three times, the time is similar to that of alcohol, and finally the tissue is immersed in molten paraffin for two to three times each for several hours, so that the paraf...
