Non-interference culture dish automatic cover opening and dish changing device used in sterile drug production area

Abstract

The invention discloses a non-interference culture dish automatic cover opening and changing device used in a sterile drug production area, which comprises a box body, bearing plates are arranged on the bottom plate of the box body and close to the left and right side plates, and jacking trays are arranged in the bearing plates; a jacking mechanism for driving the jacking tray to move up and down is arranged on the bottom plate; an arc-shaped opening matched with the upper end of the bearing disc is formed in a top plate of the box body; a culture dish dustproof cover plate supported by a front trapezoidal cross beam and a rear trapezoidal cross beam is arranged between the two arc-shaped openings on the top plate of the box body; trapezoidal beams are symmetrically arranged on the opposite surfaces of the front trapezoidal cross beam and the rear trapezoidal cross beam; a horizontal driving mechanism is arranged in the box body, a semicircular-ring-shaped pusher dog matched with the culture dishes is arranged on the horizontal driving mechanism, and the pusher dog is driven by the horizontal driving mechanism to push the culture dishes to horizontally move between the feeding area and the recycling area. According to the invention, the culture dish can be automatically replaced and the cover opening action of the culture dish can be automatically completed, and inoculation can be completed according to set time.

Description

technical field [0001] The invention belongs to the field of aseptic drug production, and in particular relates to a non-interference petri dish automatic opening cover changing device used in a sterile drug production area. Background technique [0002] The production of sterile drugs needs to meet the requirements of their quality and intended use, and the contamination of microorganisms, various particles and heat sources should be minimized. The skills, training and working attitude of production personnel are the key factors to achieve the above goals, but in fact, the human body carries a lot of microorganisms. Without disinfection, there are about 1000-6000 microorganisms per square centimeter on the hands , Healthy people also walk particles (such as human body sheds) into the environment, and they can walk 100,000 particles per minute while standing still, and the number will increase sharply when moving. [0003] However, at present, the detection of microorganism...
