Abstract: The present invention provides a polymer latex composition. The composition includes from about 35 to about 80 weight percent of aliphatic conjugated diene monomer, from about 10 to about 65 weight percent of unsaturated ester or amide monomer, and above 0 to about 15 weight percent of unsaturated acid monomer.

Abstract: A non-programmatic method for bootstrapping a user database from the web tier using pass-through server-provided form targets is disclosed. A “form target,” used in this context, is the submission destination of an HTML form, submitted via HTTP (typically this is called an “action” in HTTP). The “form target” is usually the name of a CGI script, or an alias to an ASP, Servlet or JSP on the server, which will handle a form request. When the user submits a form via HTTP, the application server will extract security data and then pass control back to an application success target or a failure target.

Abstract: A system for controlling flow through a line during intravenous drug delivery. The system is capable of use in conjunction with a bedside-pharmacy system for the preparation and delivery of intravenous drugs. The system includes a disposable cassette with first and second valve chambers and a control unit into which the cassette is capable of being received. The control unit has a cam and first and second actuators. The bedside-pharmacy system may include a liquid inlet for connection to a liquid supply, vial receptacles, and a liquid outlet for providing the intravenous drug in mixed, liquid form to the patient. That system may include a chamber having a variable volume, and a valve mechanism, which may be actuated to control flow between the liquid outlet, the variable-volume chamber, the vial receptacles and the liquid inlet.

The system may include a chamber having a variable volume, and a valve mechanism, which may be actuated to control flow between the liquid outlet, the variable-volume chamber, the vial receptacles and the liquid inlet. The system induces change in the volume of the variable-volume chamber and actuates the valve mechanism, so as to introduce liquid from the liquid inlet into the vials and reconstitute or dilute the drugs and so as to deliver the drugs to the patient. In a preferred embodiment, the liquid inlet, the vial receptacles, the variable-volume chamber, the liquid outlet and the valve mechanism (in other words, all components that come into contact with the liquid) are located in a disposable cassette, which may be received in a control unit.

Abstract: A medical irrigation pump and pump system utilize a permanent non-sterile drive motor capable of operating disposable sterile single use pump units each of which is specifically designed for a particular medical procedure. The pump units have housings which are adapted to be interchangeable within the permanent controller system. Only the sterilized and disposable pump units come into contact with the fluid pathway during pumping. A pattern of bumps on each pump unit is unique for the medical procedure for which the pump unit was designed. The pattern of bumps engages switches on the controller, enabling the controller to identify what type of pump unit has been installed. After automatically identifying the type of pump unit and the intended medical procedure, the controller automatically selects a default motor speed that will provide an appropriate fluid pressure for that particular procedure. Buttons on a control panel also enable the user to manually adjust the pressure delivered by the pump.

Abstract: The present invention is directed toward a vial-loading mechanism for a system that prepares and delivers one or more IV drugs to a patient. The vial-loading mechanism is used to load a vial onto a cassette spike and includes a vertical support member located adjacent to the spike. A holding assembly holds at least one vial. The holding assembly is mounted to the support member so as to be positionable between an upper position for loading a vial and a lower position for piercing the vial with a spike. The holding assembly has an arcuate-shaped holding member for holding the vial. A catch is provided with an engagement unit for securing the holding assembly in the lower position. This arrangement provides an easy way to add, retain, and remove vials from the system and protects the clinicians that do this from contacting the spikes and hurting themselves.
