  • Publication number: 20150361278
    Abstract: A method for treating a surface touched by people to reduce an amount of microbes transferred to people touching the surface, the method comprising the step of depositing a conformal coating onto the surface, the coating comprising an ablative layer, the ablative layer being formed of a material sufficiently soft or frangible such that the ablation layer is worn away in response to repeated human contact, said coating comprising a material that is hydrophobic when the conformal coating has cured.

  • Patent number: 6748260
    Abstract: A hand-holdable structure implementing electrodes to enable good skin-electrode contact to acquire ECG readings is disclosed. Specifically, the structure is shaped to enable patients to apply a simple gentle grip to have a reliable skin-electrode contact and to automatically commence ECG tracing transmission to a patient monitoring station. In one embodiment the structure incorporates an RF telemetry head to simultaneously transfer IMD stored data in conjunction with the ECG tracings. The structure independently or in combination with the RF telemetry head is adaptable to a system of data communications with a programmer or equivalent instrument to transfer ECG and IMD data to a remotely located physician station or patient data storage server. The system is also adaptable for use with a web-enabled network such as, without limitation, the Internet, intranet, World Wide Web, extranet or equivalent.

  • Patent number: 5316724
    Abstract: A membrane oxygenator designed to provide blood flow evenly across a gas permeable membrane in a direction substantially perpendicular to the longitudinal direction of the gas permeable membrane. In particular, the present invention is directed to a membrane oxygenator wherein the blood is distributed substantially evenly and at a substantially constant velocity, in a cross-wise direction across the gas permeable membrane. In accordance with a preferred embodiment, the membrane is a bundle of gas permeable hollow fibers with the blood being distributed in a direction substantially perpendicular to the longitudinal direction of the individual hollow fiber membranes.

  • Patent number: 5120501
    Abstract: A device including an integrally formed membrane oxygenator and heat exchange device positioned in a single housing. The device includes a thermally conductive body formed with a plurality of blood pathways on its surface, and a gas permeable membrane, or membranes positioned in the housing in substantial contact with the heat exchange body to cover or lie within a portion of each of the pathways. The membrane defines a gas pathway separate from the blood pathway through which a gas is directed. The blood is directed through the individual blood pathways. The device also includes various ports and passageways for delivering the blood to the individual channels, and for collecting and removing the blood from the device.
