Abstract: A syringe assembly may include a syringe having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end and defining an interior volume; and an indicator float provided in the interior volume of the syringe. The indicator float may be buoyant such that the indicator float is movable between the distal end and the proximal end of the syringe based on a fluid fill level within the interior volume of the syringe.

Abstract: The present invention is a device and system to permit the isolation of two fluid compounds to be delivered to a patient without intermingling the two fluid compounds, yet permitting the labor saving activity of permitting a nurse or other medical staff member to hang two IV bags simultaneously. Fluid from the first IV bag inflates the barrier pressure valve and seals the system against the intrusion of the second fluid from the second IV bag until the first fluid has been fully delivered. The barrier pressure valve then unseals the system to permit the flow of fluid from the second IV bag to the patient. This implementation permits this isolation and separate delivery of two fluids without using electronics or other technology that would require a battery backup or other uninterruptible power source.
Abstract: A method of sterilizing objects as well as the sterilized objects obtained from the method are disclosed. The method involves contacting an object such as a medical device to be reused with polycationic dendrimer under conditions which result in rendering a conformationally altered protein (e.g. a prion) non-infectious. A disinfecting agent or surgical scrub composition which comprises the dendrimers is also disclosed as are gelatin capsules treated with polycationic dendrimers.

Abstract: A hemorrhoid relief and anal hygiene device is provided including a pressure member for placement between opposing buttock surfaces in the natal cleft adjacent to the anus of the user. The pressure member has opposite side faces for each positioning against one of the opposing buttock surfaces of the user. Each of the side faces of the pressure member is substantially planar. Each of the side faces of the pressure member lie in substantially parallel planes. The pressure member has a perimeter wall that extends between the opposite side faces. The perimeter wall has a first section, a second section, and a third section. The first and second sections of the perimeter wall has inboard ends converging at a protruding crest adapted for partial insertion in the anus of the user. The first and second sections are concave for abutting opposite areas of the surface of the anus. The third section extends between outboard ends of the first and second sections.
