  • Patent number: 11660388
    Abstract: A digital syringe is used with conventional polymer disposable syringe construction to be practical in the medical environment. Errors associated with the larger volumes of the syringes (which exacerbate minor errors in plunger position) and the flexibility and dimensional variations of the polymer plungers are accommodated by direct measurement of the syringe plunger position rather than indirect measurement of motor position and inference of syringe plunger position. This direct measurement eliminates mechanical tolerances (“stack up”) in the motor, gear train, and lead screw on plunger movement, an effect exacerbated by flexibility of the plunger and changes in syringe resistance and medicament viscosity, for example, with different medicaments or when the syringe is refrigerated. The digital syringe may be combined with the motor unit to provide additional versatility.

  • Patent number: 11484656
    Abstract: A drug solution administration device includes a drug solution reservoir, a drive unit, a rotation detection unit, and a control unit. The control unit counts the number of rotations of the drive unit from when a rotation sensor value reaches a blockage start threshold value until the rotation sensor value reaches a blockage detection threshold value. Further, the control unit determines that a blockage of a flow path has occurred when the rotation sensor value reaches the blockage detection threshold value, and rotates the drive unit in a direction opposite to a direction in which the drug solution is administered based on the counted number of rotations.
