Abstract: A sanitary extubation cover used to cover an endotracheal tube and a patient's face in order to accommodate sanitary extubation. The sanitary extubation cover includes a mask and a cover which covers the endotracheal tube. If the patient coughs, the cough would be directed into the mask and the endotracheal tube (which is covered by the cover) but contaminants from the cough would be suppressed from spreading into the open air. The mask can have an air cushion at the bottom of the mask in order to securely press against the patient's face. The mask can also have a solid silicone base at the bottom of the mask in order to securely press against the patient's face.

Abstract: An automatic injection and retraction device having a longitudinal axis is provided that includes an injection assembly, a retraction assembly, and a pre-filled syringe cartridge. The injection assembly has an activation-prevention feature moveable between an on position and an off position. The retraction assembly has a needle guard that is removable in a direction along the longitudinal axis upon application of a removal force. The pre-filled syringe cartridge has a hypodermic needle with a needle sheath thereon. The retraction and injection assemblies are secured to one another so that the pre-filled syringe cartridge is in the retraction assembly with the needle sheath secured to the needle guard. The retraction and injection assemblies are configured so that, upon application of a twisting torque to the injection and retraction assemblies, the activation-prevention feature moves from the on position to the off position simultaneous with applying the removal force to the needle guard.

Abstract: A coupling for selectively securing a spring to a plunger is provided. The coupling has a first end defining a spring rest for receiving the spring and a second end defining a shoulder. The shoulder is moveable to a first position into contact with the plunger and to a second position out of contact with the plunger. The shoulder is normally in the second position and is resiliently moveable to the first position.

Abstract: An automatic injection and retraction syringe having a medicine cartridge, an injection assembly, and a retraction assembly is provided. The retraction assembly is selectively securable to the injection assembly to house the medicine cartridge. The retraction assembly includes an end cap, a hypodermic needle, a retraction spring, and an upper seal. The retraction spring is maintained in a partially compressed condition between the needle hub and the end cap. The upper seal is urged against a sealing surface by the retraction spring in the partially compressed condition to form a hermetic seal. In some embodiments, the injection assembly includes an injection spring, a plunger engaged to the injection spring, and a safety element to prevent the plunger from escaping the injection assembly if the injection spring is released from the normally stressed condition before the assemblies are secured to one another.

Abstract: A fixed needle syringe having a medicine compartment, a hypodermic needle, a piston, and a plunger is provided. The hypodermic needle is in fluid communication with the medicine compartment. The piston is slideably disposed in the medicine compartment. The plunger is secured to the piston. The plunger has a bore defined therethrough, where the bore allows access to the piston through the plunger.

Abstract: The invention provides a method and system for reducing latency in reviewing and presenting web documents to the user. A cache coupled to one or more web clients request web documents from web servers on behalf of those web clients and communicates those web documents to the web clients for display. The cache parses the web documents as they are received from the web server, identifies references to any embedded objects, and determines if those embedded objects are already maintained in the cache. If those embedded objects are not in the cache, the cache automatically pre-fetches those embedded objects from the web server without need for a command from the web client. The cache maintains a two-level memory including primary memory and secondary mass storage. At the time the web document is received, the cache determines if any embedded objects are maintained in the cache but are not in primary memory.
