Intelligent full-closed biological tissue dehydrator

Abstract

The invention discloses an intelligent full-closed biological tissue dehydrator, which has the following characteristics that: a specimen and a reagent complete a full dehydration process in a sealed space; equipment is detected before a program runs; whether liquid supply and liquid discharge are normal can be automatically judged in the running process; if a fault appears, the fault can be automatically recovered; if the fault cannot be recovered, an automatic protective program is operated, and remote alarm can be given through a telephone; if power is cut off in the running process, continuous running or entry of a power-off protective program can be automatically selected according to the running reagent; the dehydrator can be used for normal pressure dehydration, vacuumizing dehydration, positive pressure dehydration, positive and negative pressure alternated dehydration and ultrasonic quick dehydration; the dehydrator also has a function of automatically detecting the concentration of paraffin dissolved in a cleaning agent; particularly an annular electromagnetic distribution valve is designed, and the reagent does not have residue; the paraffin cleaning agent, the paraffin and the common reagent enter a working cylinder in three paths, so that the fault is lower; and the dehydrator is provided with a special working cylinder locking mechanism, a special spare bottle and a special protective bottle.

Description

technical field [0001] The intelligent full-seal biological tissue dehydrator of the present invention is a kind of inspection auxiliary equipment, which is mainly used for dehydration and wax dipping of animal and plant tissues. Background technique [0002] The existing biological tissue dehydration machine is mainly driven by the mechanical part to run one reagent cylinder and one test cylinder for specimen tissue, and some reagents have carcinogenic effect, while the reagent cylinders of ordinary dehydration machines cannot be sealed, and they are easy to volatilize and cause environmental pollution. damage to the health of workers. Contents of the invention [0003] 1. Let the specimens and reagents complete the whole process of dehydration in a sealed space; [0004] 2. Before running the program, self-check the equipment first, mainly check the sealing of the working cylinder and pipeline, whether the positive pressure, negative pressure, and the heating of each pa...
