摘要:
A picture frame includes four legs delineating a rectangular opening and coupling members joining the adjacent ends of the legs, each leg including a longitudinal outer web, a high front flange and a low rear flange projecting upwardly from the web front and rear edges and coplanar legs projecting toward each other from the flanges to form confronting channels and each coupling member includes a corner angle section with arms terminating at their ends in mutually perpendicular faces and rectangular tongues offset from the edges of and projecting from the ends faces into sliding engagement with the channels of adjacent frame legs, the front and peripheral faces of the end sections being coplanar with the leg front flange front faces.

A picture frame has a lip for supporting the front of a picture and at least one groove. Resilient means, such as spring clips, have tongues for insertion into the groove. The clips support the rear of the picture and can hold pictures of varying thickness. A second groove can be disposed behind said first groove for holding extra thick pictures, such as canvasses.

A detachable stylet assembly for endotracheal intubation of a patient is disclosed. The stylet comprises an elongated tube defining: a longitudinal axis, a proximal end for detachably mounting the stylet to a hand grip, and a distal end for entering the trachea of the patient. The tube comprises an articulation section adjacent the distal end adapted to curve into the trachea upon actuation. An actuator housing is mounted on and adjacent to the proximal end of the tube. An actuating assembly is constructed inside the actuator housing having connection means for engaging the hand grip. A control wire is mounted within the actuator housing and connected to the actuating assembly. The control wire extends through the tube to the distal end of the tube and is adapted to curve the articulation section upon actuation. The hand grip comprises a base handle and a trigger for manual actuation of the actuator assembly. The trigger comprises finger grooves for convenient gripping. The base handle comprises a hand stop to prevent slippage.

A stylet assembly for performing a nasal endotracheal intubation of a patient is disclosed. The stylet assembly includes an elongated tube as a stylet for the intubation defining a longitudinal axis, a proximal end, and a distal end for entering the trachea of the patient. The elongated tube includes (i) a rigid section adjacent the proximal end, (ii) an articulation section adjacent the distal end and adapted to curve into the patient's trachea upon actuation, and (iii) a flexible section between the rigid section and the articulation section, the flexible section being adapted to curve to an internal shape of at least one of the patient's nose, nasal cavity, pharynx, and larynx during nasal intubation. The stylet assembly can further include an actuator housing, a control wire for actuating the articulating section, and a hand grip for maneuvering the stylet assembly.
摘要:
The present invention provides novel MDCK-derived adherent non-tumorigenic cell lines that can be grown in the presence or absence of serum. The cell lines of the present invention are useful for the production of vaccine material (e.g., viruses). More specifically, the cell lines of the present invention are useful for the production of influenza viruses in general and ca/ts influenza viruses in particular. The invention further provides methods and media formulations for the adaptation and cultivation of MDCK cells such that they remain non-tumorigenic. Additionally, the present invention provides methods for the production of vaccine material (e.g., influenza virus) in the novel cell lines of the invention.
摘要:
A method for supporting communication between a source internet protocol phone and a destination internet protocol phone is provided. The source internet protocol phone communicates via a Network Address Translator (“NAT”) gateway. The method includes receiving a packet from the source phone at the NAT. The packet is for communication with the destination phone. The method further includes querying whether the destination phone is located in the subnetwork serviced by the NAT gateway. If the destination phone is not located in the subnetwork serviced by the NAT gateway, then the method includes sending the packet upstream to the destination phone via the Internet. If the destination phone is located in the subnetwork serviced by the NAT gateway, then the method includes directing the packet to the destination phone.

Methods and compositions for the optimization and production of influenza viruses, e.g., ca influenza B strains, in eggs and host cells suitable as influenza vaccines are provided.
摘要:
The present disclosure provides for a guide adapted for facilitating insertion of a medical device into the trachea of a patient. The guide comprises an integral curved-shaped member having at least a first leg at one end of the guide. The curved-shaped member consists essentially of an outside curved side defining a concave groove. A first angle is defined on the first leg configured and dimensioned to allow for at least the first leg to pass through the mouth and into the trachea of the patient. Insertion of the guide into the trachea allows for elevation of the tongue and surrounding soft tissue of the patient thereby forming an air space that allows for passage of a medical device.
