Abstract: A mechanical infusion pump device for injecting medication into a patient's IV, includes an IV reservoir and a syringe communicated to the IV reservoir and having a syringe plunger connected to a filling plunger that is moved with the syringe plunger in a first syringe-filling direction to fill the syringe with fluid medication. Biasing weight(s) is/are provided on the filling plunger for exerting bias or force from gravity on the filling plunger and the syringe plunger in a second syringe-discharging direction to dispense medication from the syringe into the patient's IV when the filling plunger is released. Only a calibrated amount of medicine can be discharged to the patent's IV over time as determined by calibration of the biasing weights and the metering element located between the syringe and the patient's IV for a given viscosity of the medication.

Abstract: A mechanical infusion pump device for injecting medication into a patient's IV, includes an IV reservoir and a syringe communicated to the IV reservoir and having a syringe plunger which is moved in a first direction against a mechanical biasing element by engagement with a manually operable, independently movable filling plunger to fill the syringe with fluid medication. The mechanical biasing element is provided for exerting bias on the syringe plunger in a second syringe-discharging direction to dispense medication from the syringe into the patient's IV when the filling plunger is released. Only a calibrated amount of medicine can be discharged to the patent's IV over time as determined by calibration of the biasing element and a metering element located between the syringe and the patient's IV for a given viscosity of the medication.

Abstract: A mechanical patient-controlled analgesia device for injecting medicine into a patient's IV, includes an IV reservoir and a syringe communicated to the IV reservoir and having a syringe plunger. A mechanical biasing element is provided for exerting bias on the syringe plunger in a first syringe-filling direction to draw medicine from the IV reservoir into the syringe. An injection plunger is operable by the patient to move the syringe plunger in a second injection direction against the bias to inject the medicine in the syringe into a patient's IV. The injection plunger is movable independently of the syringe plunger and is engaged with but unconnected to the syringe plunger when the patient moves the injection plunger to inject the medicine. The patient can inject only a calibrated amount of medicine drawn into the syringe as determined by calibration of the biasing element and a metering element for a given viscosity of the medication.
