  • Publication number: 20160030727
    Abstract: This invention provides an implantable infusion port which comprises a non planar septum, a fluid reservoir of a substantially spherical shape, inlet means to access the reservoir, and optimized outlet means from the reservoir. The present invention provides for a reservoir that precludes angular junctions between portions of the reservoir which can lead to eddies, countercurrents, and stagnation, thereby creating a more laminar and efficient flow pattern within the reservoir.

  • Patent number: 7794445
    Abstract: A fluid delivery device for delivering fluid to a patient includes a fluid delivery tube, a needle in communication with the fluid delivery tube, a base connected adjacent a distal portion of the fluid delivery tube and a flexible shield connected at one end to the base. The shield includes an adhesive portion located on an outer surface, wherein in an insertion configuration the needle fits through a shield aperture and the adhesive portion contacts a target skin region, and when in a protection configuration a needle tip contacts a portion of an inner surface of the shield spaced apart from the shield aperture when the fluid delivery device is removed from the skin region.

  • Patent number: 7150726
    Abstract: The invention provides a subcutaneous infusion device including a delivery tube having a central lumen and a closed first end and an open second end. The device further includes a support base attached adjacent a first end of the delivery tube; and a plurality of needles extending substantially perpendicular to the support base and in communication with the central lumen of the delivery tube. A method for hydrating a patient in accordance with the invention includes pressing a support base against a skin surface of the patient and inserting a plurality of needles into a subcutaneous skin layer responsive to the pressing. The method further includes delivering a saline fluid to the subcutaneous skin layer through the needles via a delivery tube.

  • Patent number: 6884224
    Abstract: A needle safety and protection device that automatically caps the used tip of a needle the instant the needle is withdrawn from the patient to protect the user against infection risks. A spiral type cut safety shield remains relaxed until the device comes in contact with the patient's skin. The safety shield attaches to the patent's skin through an adhesive component creating a tensile force once the needle is withdrawn, extending the safety disk out of its relaxed position. Under tension, the safety disk creates a cone around the needle, forming a protective shield for the needle, without any assistance by the user. The tip of the needle then engages a portion of the shield, which prevents the tip from being re-inserted into the skin of the patient or the user of the needle.
