Calibrating device for medicinal vacuum freeze dryer

Abstract

The utility model relates to the technical field of equipment calibration, in particular to a calibration device for a medicinal vacuum freeze dryer, which effectively improves the detection efficiency and the measurement accuracy by arranging a temperature and vacuum degree integrated detection device. A small-size calibration device is arranged, and a long rod is a straight rod and can be inserted into liquid medicine in a penicillin bottle and then placed in a plate layer; a plurality of upper through holes are formed in the top wall of a shell, a pressure sensor is attached to the lower portions of the upper through holes, and the outer edge of the pressure sensor comprises the outer edges of all the upper through holes, so that the vacuum degree is accurately measured; the supporting unit is fixedly connected to the bottom face of the shell, it is guaranteed that the long rod vertically extends to the lower end all the time when the main body unit is stably placed on a bottle opening of the penicillin bottle, and the temperature of liquid medicine in the penicillin bottle is accurately measured; the electronic unit comprises a single chip microcomputer, a memory, a wireless communication module and a Hall module, one or more off-line calibration devices can be controlled at the same time through software, and the use reliability and accuracy of the medicinal vacuum freeze dryer are ensured.
