  • Publication number: 20220287606
    Abstract: Measurement system which can be used at patients bedside to monitor the amount of blood drawn from the patient. The system uses disposable sensor and electronics to measure accurately and in real time the volume of the blood drawn from the patient using a paddlewheel sensor wherein the rotation of the paddle wheel is correlated with the volume of the blood that is drawn from the patient and collected.

  • Publication number: 20220002130
    Abstract: A system and method for a self-actuating, mechanically-biased container restraint. The system requires no computer-aided control or timing, nor is any external power source needed, other than the force exerted as a container is inserted into the restraint. The system relies upon an assembly including mechanically-biased pivoting levers, each of which has a horizontal element and a vertical element. All actuation occurs as the base of an inserted container comes into contact with the upper surface of the horizontal elements of multiple pivoted levers positioned at the base of a channel adapted to serve as a guide for the inserted tube. The levers are biased in this elevated position by mechanical means, such as a spring. As the inserted tube presses the horizontal members downward, the top portions of the vertical members are pivoted inward toward the container's exterior.

  • Publication number: 20210147206
    Abstract: A system and method for gripping, torqueing and releasing an element so as to cap and/or decap a container, such as those typically utilized to house specimens in laboratory environments. The system is driven by a single bi-directional motor linked to a coupler assembly via a rotating threaded shaft. The coupler assembly is configured to engage with an element, such as a cap or container, via mechanically-biased splines that are actuated without any complex linkages, or operative connection to the motor or other powered components. The system employs an ejector nut and an ejector, both of which are concentrically positioned about the threaded shaft. The ejector nut translates along the shaft as a function of the shaft's rotation, so as to permit the retraction of the ejector when an element is engaged in the coupler assembly or cause the ejector to extend into the coupler assembly to disengage the element.
