摘要:
A breathing assistance apparatus includes an inner volumetric member pressurizable from a first pressure to a second pressure and an outer volumetric member surrounding at least a portion of the inner expandable volumetric member. The inner volumetric member pressurizes the outer volumetric member as the inner volumetric member is pressurized from the first pressure to the second pressure. In another embodiment, a breathing assistance apparatus includes exhalation and inhalation chambers with respective biasing members providing for the exhalation chamber to apply a pressure to the inhalation chamber and thereby provide assisted inhalation. Methods for assisting breathing are also provided.

An adapter for use in a breathing circuit including a housing with a conduit having a ventilator port adapted to be coupled to a breathing circuit and a patient port adapted to communicate with a patient interface. A medicament container receptacle communicates with the conduit between the ventilator port and the patient port. The receptacle includes a support block having a well shaped to receive a valve stem extending from a container of medicament and an actuator finger extending upwardly in the receptacle adjacent the support block. The actuator finger is adapted to actuate a dose counter coupled to the container.

Processes for preparing alkylation aromatic compounds are provided herein. In an embodiment, a process for preparing alkylated aromatic compounds includes reacting an aromatic compound and an olefin in a first alkylation reaction in the presence of a first alkylation catalyst to produce a first effluent that includes an alkylated aromatic compound and unreacted aromatic compound. Unreacted aromatic compound from the first effluent and additional olefin are reacted in at least one downstream alkylation reaction in the presence of a second alkylation catalyst to produce a second effluent including the alkylated aromatic compound. A recycle stream including the alkylated aromatic compound is recycled from the second effluent to the at least one downstream alkylation reaction and, optionally, the first alkylation reaction. A ratio of the recycle stream to a total mass flow is greater in the at least one downstream alkylation reaction than in the first alkylation reaction.

In a modular medicament delivery system, a dispenser housing has a support block with a well and an orifice communicating with the well. A first container assembly includes a valve stem shaped to be received by the well in the support block. The first container assembly has a first exterior shape. A second container assembly includes a valve stem shaped to be received by the well in the support block. The second container assembly has a second exterior shape that is different than the first exterior shape. An insert member is adapted for mounting to the dispenser housing in the cavity and defines an interior space shaped to receive the second exterior shape of the second container. Methods of assembling the system, a system kit and a device are also provided. A medication delivery device includes first and second end pieces and a collapsible chamber disposed therebetween.

Ventilator circuit aerosol delivery systems used to administer medication to a patient are disclosed. In one implementation, a metered dose inhaler (“MDI”) ventilator assembly may include a housing that defines an interior space, an inhalation port that defines an inhalation passageway in communication with the interior space, an exhalation port that defines an exhalation passageway in communication with the interior space, a patient port that defines a patient passageway in communication with the interior space, and a MDI receptacle positioned on the housing and in communication with the interior space. The MDI receptacle is operative to receive a MDI container and dispense an aerosolized medication within the MID container into the interior space so that during inhalation, an inhalation flow including the aerosolized medication may flow through the inhalation port, the interior space, and the patient port. Conversely, during exhalation, gases, moisture, condensation, and/or mucus expelled from the patient flow through the patient port, the interior space, and the exhalation port.
摘要:
In this application is described substrates for high-throughput assays of clostridial neurotoxin proteolytic activities. Two types of substrates are described for use in assays for the proteolytic activities of clostridial neurotoxins: (1) modified peptides or proteins that can serve as FRET substrates and (2) modified peptides or proteins that can serve as immobilized substrates. In both types a fluorescent molecules is present in the substrate, eliminating the requirement for the addition of a fluorigenic reagent. The assays described can be readily adapted for use in automated or robotic systems.
摘要:
A deflector for a discharge outlet of a tailings conveyor of a harvesting machine for providing tailings dispersal over a sieve of a cleaning system or other location on the harvesting machine, without significantly interfering with crop material flow from a threshing system of the combine and while also preventing entry of crop material from the threshing system into the conveyor outlet.
摘要:
Photographic glass plates can be prepared by directly coating the appropriate layer formations onto a glass support. One element comprises a thin subbing layer (less than 2 .mu.m), an antihalation layer, a silver halide emulsion layer, and a protective overcoat layer that can also include a matting agent or lubricant. Another embodiment has the antihalation layer coated directly onto the support.
