  • Patent number: 11761974
    Abstract: A cell and medicament dispensing device for drug screening is configured to dispense minute amount of cells and medicaments. The device has a base, a transfer plate serving mechanism, a transfer plate positioning mechanism, an injection mechanism, a cell culture plate positioning mechanism, and a dispensing mechanism. The transfer plate serving mechanism moves a transfer plate to the transfer plate positioning mechanism. The injection mechanism injects cells and medicaments into recesses in the transfer plate. A cell culture plate is fixed in the cell culture plate positioning mechanism. The dispensing mechanism moves back and forth between a position above the transfer plate and a position above the cell culture plate to dispense the cells or medicaments from the transfer plate to the cell culture plate. As a result, the process of drug screening is automated to reduce labor and improve quality significantly.

  • Patent number: 11744242
    Abstract: A living body specimen transport device for receiving multiple living body specimens has a frame, a rotating bracket, and a storage assembly. The rotating bracket can be rotated with respect to the frame. The storage assembly can receive a container with a living body specimen and be rotated with respect to the rotating bracket. A center of gravity of the storage assembly is lower than a pivoting point where the rotating bracket is mounted on the frame and a pivoting point where the storage assembly is mounted on the rotating bracket. With such structure, even when the living body specimen transport device is vibrated and shaken during transporting and then the frame of the living body specimen transport device is tilted or turned over, the rotating bracket and the storage assembly can rotate to be vertical by themselves, which keeps the living body specimen being soaked in the preservation solution.
