  • Publication number: 20260031211
    Abstract: A pump for administering an agent to a patient includes a housing, a motor, a gearbox, a sensor, and a controller. The motor may be coupled to housing. The gearbox is operatively connected to the motor. The sensor senses a rotation of the motor. The controller acts to control operation of the motor and monitor the quantity of the agent delivered to the patient. The pump also includes a pump assembly such that the pump is configured such that the pump assembly may be interchangeable from a syringe pump assembly and a peristaltic pump assembly.

  • Publication number: 20240082487
    Abstract: A syringe pump includes a lead screw, a cam, and a grasper. The grasper assembly has first and second graspers arms each having a first end and a second end. The second ends of the first and second grasper arms are configured to engage with the lead screw. The first ends of the first and second grasper arms are configured to engage with the cam such that actuation of the cam toward the grasper assembly causes the second ends of the first and second grasper arms to pivotally approach each other. The second ends of the first and second grasper arms each includes threads to engage the lead screw when the second ends of the first and second grasper arms approach each other. The plunger head coupled to said grasper assembly and operative to drive a plunger of a syringe into a barrel of said syringe.

  • Patent number: 11129933
    Abstract: A method for discharging fluid from a syringe and for mitigating occlusion conditions includes actuating the plunger of a syringe into a barrel. The method monitors fluid pressure within the barrel of the syringe and determines that an occlusion exists when the fluid pressure exceeds a predetermined threshold. The method actuates the plunger out of the barrel by a predetermined amount in response to the detected occlusion and actuates the plunger of the syringe into the barrel until a measured fluid pressure within the barrel of the syringe exceeds another predetermined threshold.
