This invention relates to new apparatuses for draining material from a stomach and infusing fluid into the stomach comprising a tubing connector, a housing unit, and a one-way valve. In an embodiment the connector can have a first port, a second port, a third port and a branched lumen that extends through each of the first, second and third ports. The housing unit can have a housing lumen that is sized and shaped to receive the third port and the housing unit is sized and shaped to receive the connector. The one-way valve can be sized and shaped to be received in the housing lumen.

Apparatus and method for draining material from a stomach

A piston-type infusion pump is provided having an improved method of occlusion detection. The infusion pump includes processing circuitry for controlling the drive mechanism to infuse medication to a patient, including a sensor to track the position of the syringe plunger, thereby metering the amount of medication dispensed to the patient. The processing circuitry also includes a force sensor for providing signals indicative of the presence of occlusions along the infusion path. The operation of the drive mechanism causes delivery of medication to the patient. The infusion pump is constructed to be watertight.

Infusion pump with a sealed drive mechanism and improved method of occlusion detection

A syringe for use with an infusion pump, the infusion pump having a cavity for receiving the syringe. The syringe includes a syringe body, a plunger and an end cap. The syringe body has a tube that is open at a first end and transitions to a passage at a second end and a connector extending from the passage, the connector for attachment to an infusion set or tubing. The plunger is slidably mounted inside the tube and comprises a plunger tip and a plunger rod. The plunger tip has a front face that is complementarily received by the second end of the tube and a rear face, the plunger tip forming an interference fit with the tube. The plunger rod has a first end attached to the plunger tip and a second end extending outside the first end of the tube. The plunger rod has a cross-sectional shape that is complementarily received by the cavity of the infusion pump when inserted in only one direction. The end cap is attached to the first end of the tube and has an opening that is shaped to complementarily receive the plunger rod.
