Embodiment Construction

[0017] Such as figure 1 Shown, a kind of vibrating equipment of cell culture liquid comprises signal generator 8, the first loudspeaker 10 that is electrically connected with signal generator 8, and first loudspeaker 10 comprises first magnet 12, first basin frame 14 and first vibration Membrane 16, the first diaphragm 16 promotes vibration of the cell culture fluid. The signal generator 8 generates signals of various frequency bands, and transmits them to the first speaker 10, and the first diaphragm 16 of the first speaker 10 vibrates, thereby prompting the cell culture liquid to vibrate.

[0018] The beneficial effect of the present invention is that the vibration of the first diaphragm 16 of the first loudspeaker 10 is used to promote the vibration of the cell culture solution, which has high sensitivity, thus high detection accuracy and wide applicable frequency range.

[0019] In this preferred embodiment, it is possible to detect the influence of the vibrations generat...

Abstract

The invention discloses vibrating equipment of cell culture fluid. The vibrating equipment of the cell culture fluid comprises a signal generator and a loudspeaker which is electrically connected with the signal generator, the loudspeaker comprises a magnet, a basin frame and a vibrating membrane, and the vibrating membrane promotes the cell culture fluid to vibrate. According to the vibrating equipment of the cell culture fluid, vibration of the vibrating membrane of the loudspeaker is utilized to promote the cell culture fluid to vibrate, the sensitivity is higher, and the applicable frequency range is wider.

Description

technical field [0001] The invention relates to a vibrating device for cell culture fluid. Background technique [0002] Existing cell analysis techniques usually analyze the liquid by detecting the liquid impedance value, and detect the growth state of the cell by analyzing the change of the liquid impedance. However, the same oscillation frequency may correspond to two different impedance values. And if an external frequency is added, the detection is prone to errors. And when the applied frequency is higher than the liquid resonance frequency, the impedance value may not be detected, and the measurement sensitivity is not enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vibration device for cell culture fluid, which has high sensitivity and wide application range. [0004] The present invention is the technical solution adopted for solving the above-mentioned technical problems: [0005] A vibrati...
