IPC: A61F5/445

Abstract: This invention is intended for use primarily as a medical device, predominantly relating to ostomy equipment. Traditional ostomy pouch clamps employ a snap lock at their distal end manufactured from plastic or similar materials. They are also vulnerable to snags, most commonly on clothing, leading to unwanted opening of the clamp. With continued wear, these snap locks begin to soften and produce a less reliable closure. The Ostomy Pouch Clamp Ring Fastener provides a redundant mechanism by which the clamp seal is reinforced to prevent opening. This provides added confidence for the wearer and increases the useable life of a traditional ostomy pouch clamp. Canadian Patent CA 2424404 and US Patent 6702794 detail a traditional Ostomy Pouch Clamp. The basic mechanism involves a hinged 2-member design whereby a blade member inserts into a trough member and a snap lock on the distal end provides closure.  This design was further improved, per the above patent, by means of adding a mechanical interlock along the entire length of the clamp. While providing added security, this mechanism requires added dexterity on the part of the user to disengage/reengage the snap lock while also creating accelerated wear-down of the pouch itself. Both the basic design (snap lock only) and enhanced design (full mechanical interlock) can both benefit from the redundancy of a ring fastener. Even upon snap lock failure, the ring fastener when engaged prevents full opening of the clamp and prevents the release of pouch contents.

Abstract: A nuclei formation step of reacting an organic buffering agent having a piperazine ring with a solution of a first gold salt to form nuclear gold nanoparticles and a growth step of growing the nuclear gold nanoparticles by simultaneously adding a solution of a second gold salt and an organic acid having reducing properties to the solution of the nuclear gold nanoparticles to cause the reaction of these components are carried out. Thus, it becomes possible to readily produce gold nanoparticles which can be dispersed into a colloid solution having a blue color as determined by visual examination and each of which comprises an organic buffering agent having a piperazine ring, gold and an organic acid having reducing properties. The gold nanoparticles thus produced can be used as labeling particles for use in immunological measurement methods.

Abstract: A coupling device that implements a related method for remote powering wide band digital telecommunication devices through telephone lines or coaxial cables installed in all buildings, has an AC blocking transistor inserted in the electrical path from a voltage supply line to the telephone line or coaxial cable. The transistor has a first current terminal coupled to the supply line and a second current terminal coupled to the telephone line, and it is controlled with a DC control voltage such to keep it in a substantially linear functioning condition at the edge of a saturation condition during the normal functioning whatever the supply current that flows through the transistor is, destined to the connected telecommunication devices. This may be done by properly generating this control voltage by means of a dedicated voltage generator, or by nulHfying the DC component of the difference of potential between the control terminal and the second current terminal, for example through a low-pass filter that generates the voltage on the control terminal as a low-pass replica of the voltage on the second current terminal.
