A bracket can be affixed to a fixed plate or an adjustable plate and a cooperating tab can be affixed to the other plate for securing a catheter there between. In a modification, a fixed plate is affixed to the pad and a pair of adjustable plates can be rotatably secured on the fixed plate. Secured on the fixed plate are upright tabs and secured on the adjustable plates are brackets that are adapted to cooperate with the tabs. The adjustable plates can be rotatably moved so as to retain a catheter between the respective cooperating brackets and tabs. In a further modification, a base is secured to a pad and a pair of plates or arms are pivotally mounted on the base for rotation with respect to one another. Complementary pawl and ratchet members are used to enable limited rotation of the plates or arm with respect to one another and to fix the plates or arms in selected adjustment position.05-19-2011
20110106048FLUID FLOW CONTROL SYSTEM HAVING CAPILLARY FLUID FLOW RESTRICTOR - A fluid flow rate control system and method comprises a capillary tube having a proximal end that projects into a chamber with a cross-sectional area that is larger than or equal to the fluid supply tube's cross-sectional area. The inner cross-sectional area of the capillary tube is configured less than the inner cross-sectional area of the chamber. The chamber has a volume large enough to slow the fluid conducted to it by the upstream fluid line to permit contaminants to fall out of solution. In another aspect, a sleeve is used to mount the capillary tube into the chamber. The sleeve provides a mounting surface for tube segments from the pump and downstream of the capillary restrictor.05-05-2011

20110068922INVENTORY MONITORING AND VERIFICATION SYSTEM - Methods and systems for monitoring the inventory of products in a storage device that has an antenna are provided, wherein each product has a corresponding wireless tag having a unique wireless tag identification. The inventory monitoring includes accessing an inventory list containing at least one wireless tag identification, sending a specific query via the antenna for each of the at least one wireless tag identifications in the inventory list to the corresponding wireless tag, verifying, in the case that a response is received from the wireless tag corresponding to the wireless tag identification, that the product corresponding to the wireless tag is present in the storage device, determining, in the case that a response is not received from the wireless tag corresponding to the wireless tag identification, that the product corresponding to the wireless tag is not present in the storage device, and updating the inventory list based on the products verified to be present and the products determined to not be present in the storage device.03-24-2011
20110066260SYSTEM AND METHOD FOR DYNAMICALLY ADJUSTING PATIENT THERAPY - A system and method of managing therapy provided to patients in an institution. The system monitors all aspects of the medication delivery to a patient, as well as other information related to the patient, such as values of vital signs, laboratory results and patient factors such as history, diagnosis, allergies and the like. The system includes one or more databases of information, including institutionally developed rules, guidelines and protocol representing the best medical practices of the institution. The system provides alerts and/or recommendations based on the application of the rules to the information being monitored, and alerts care givers accordingly, providing for dynamic adjustment of the patient's therapy. The system also monitors the status of the alerts, and if no action is taken in a selected period of time, may escalate the priority of the alert and/or halt the delivery of medication to the patient until the alert is resolved.03-17-2011
20110060758MEDICATION MANAGEMENT SYSTEM - A system and method for confirming that a medication administration device has been programmed with the correct medication administration parameters. A medical database carrier is used compare medication delivery parameters entered into a medication administration device to institutionally established guidelines or more widely accepted protocols to ensure that the medication is delivered in accordance to those guidelines. The medical database carrier may also be configured to communicate information regarding medication delivery and other patient information between a control system in communication with the care-giving facility's other information systems and a patient specific asset such as an infusion pump. The medical database carrier may be a smartcard, a PDA such as a Palmâ„¢ Pilot, laptop computer, pager, mobile phone, or other device capable of storing, processing and communicating information. The system may use either wired or wireless connections to communicate information between the components of the system.03-10-2011

Each configuration database preferably includes protocols, operating limits, rule sets and/or operating features that collectively define an operating environment, or personality, of the device. Selection of a specific configuration database preferably is based at least in part upon patient-specific information obtained from any location in a distributed hospital network. Examples of such patient-specific information include patient age or size, patient medical characteristics, a location of the patient or a location of the care device. In a preferred embodiment, programming a patient care device to deliver a drug to a patient entails activating a configuration database and scanning a machine-readable drug label identifying a particular protocol stored in the activated database. The selected protocol includes default parameters for delivering the drug, and the label optionally includes instructions for deviating from the default protocol.02-03-2011
