摘要:
A dialysis valve includes a tube attached between an artery and a vein which, when elongated, simultaneously narrows in diameter at at least one location. The narrowed portion of the tube decreases the volume and velocity between the arterial and venous side of the patient to prevent damage or intimal hyperplasia on the venous side between dialysis treatments. When the valve is opened for dialysis, an unrestricted blood flow exists between the arterial and venous side, permitting a controlled, open blood flow during dialysis.
摘要:
A retention device for anchoring indwelling catheters, sheath introducers, feeding tubes, ostomy bags or other medical devices beneath the skin of a patient includes an deployable section coupled to a medical device; following introduction into a patient, the deployable section is subcutaneously deployed, securely anchoring the device and coupled medical device for the duration of treatment.
摘要:
Some embodiments of an anchor device may include bendable anchor mechanism that is deployable in a subcutaneous layer to releasably secure the anchor device to a patient's body. Certain embodiments of the anchor mechanism may include one or more barbs that flexibly bend in response to an insertion or removal force. As such, the anchor mechanism may be inserted into a subcutaneous layer, and removed from the subcutaneous layer, without the need for a separate actuation device to extend or retract the barbs.

摘要:
An apparatus for preparing formaldehyde from methanol by dehydrogenation in a reactor in the presence of a catalyst at a temperature in the range from 300 to 1000° C., a carrier gas stream which has a temperature above the dehydrogenation temperature is fed to the reactor.
摘要:
A system for storing and dispensing game cartridges and a method for the same. A housing system that requires a user to store a game cartridge in the apparatus before another game cartridge in the apparatus can be dispensed. Thus, insuring that game cartridges will be returned to a storage apparatus before another game cartridge is removed thereby preventing game cartridges from being lost and keeping all game cartridges not being played in one storage container.
摘要:
Some embodiments of a medical device anchor system include an anchor device that receives a medical instrument (such as a catheter or the like) and secures the instrument in place relative to a skin penetration point. In some circumstances, the anchor device may allow the anchor device to be used after medical instrument is already in place without the need for a second penetration point for the anchor device.
摘要:
Method and system are disclosed for dynamic probing of software. The dynamic probe is capable of being inserted into (or removed from) the software under test during run-time. This dynamic insertion (and removal) of the probe allows the user to insert and remove probes as needed instead of recompiling the software in order to insert new probes. Also, the dynamic insertion (and removal) of probes saves memory space by allowing the user to add probes only as needed and to remove probes that are no longer being used. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
摘要:
A process for the post-purification in particular of pyrolysis gases for preparing pure formaldehyde, hemiformal being pyrolyzed in an evaporator, the resulting formaldehyde vapor being passed through a condensed liquid component collected in the bottom area of the evaporator, the condensed liquid component being passed out as a falling film situated on the inner wall through a cooled outlet tube disposed in the bottom area of the evaporator and the formaldehyde vapor being passed through the cooled outlet tube in cocurrent and the liquid component and the formaldehyde being taken off separately at the outlet tube end remote from the evaporator.
