  • Patent number: 11850395
    Abstract: A syringe pump can be operated to produce fluid flow from a syringe installed therein. Features of the pump can produce a desired rapid commencement of flow followed by smooth delivery uninterrupted by stiction-induced slowing and acceleration. A stiff drivetrain can facilitate detection of excessive forces indicative of friction at a stopper-wall interface. The motor drive, gearing, and control parameters can enable customized acceleration patterns to determine optimal initial stage advancement to provide fluid delivery. These patterns can minimize or eliminate the delay in commencement of flow by overcoming both mechanical slack remaining and syringe stopper slack. To avoid flow irregularities produced by stiction forces in the stopper further, a mechanical vibration can be provided to the syringe and/or barrel to introduce movement of the stopper-wall interface, reducing the creation of high static friction coefficients.

  • Patent number: 11819643
    Abstract: A device for one-handed insertion of a hollow needle and a guidewire includes a grip, an actuator carriage, a wire guide feed mount, a wire feed surface, and a plunger with a guidewire passage colinear with the needle. The actuator carriage has a trigger and is coupled with the plunger. The wire guide feed mount is mounted on the actuator carriage and has a guide fitting that couples with the plunger and directs the guidewire through the plunger. When the grip is engaged by one hand, a digit of the hand can advance the guidewire through the plunger by engaging the guidewire between the digit and the wire feed surface, sensing a degree of resistance encountered by a tip of the guidewire, with another digit of the hand urging the trigger and drawing the plunger rearwardly and/or forwardly, while the hand continues to engage the grip.

  • Patent number: 11819673
    Abstract: In some embodiments a system and method are described for safeguarding a hazard. The hazard, for example a needle point, may be moved between a protected retracted position, an active extended position and/or an intermediate position. Optionally in the retracted position, the hazard may be protected inside a housing. Optionally in the extended position, the hazard may be exposed. Optionally, in the intermediate position the hazard may be partially protected and/or concealed, for example by a shield and/or in an indentation. In some embodiments, compromising a shield causes the hazard to be retracted to the retracted position.
