Abstract: A method of determining a pressure of a body cavity with a controller of a fluid management system includes determining a pressure and a volume of a cuff disposed about a collapsible bag, determining a volume of the collapsible bag based on the pressure and the volume of the cuff, and determining a pressure of the collapsible bag based on the volume of the collapsible bag. The method also includes calculating a fluid flow from the collapsible bag into a body cavity from the collapsible bag and determining a pressure of the body cavity based on the fluid flow.

Abstract: The present disclosure relates to a administration assembly for a medicament delivery device, comprising: an elongated tubular delivery member cover (7), a cartridge holder (11) configured to be received by the delivery member cover (7) and configured to accommodate a medicament cartridge (31), the cartridge holder (11) having a radially flexible and radially inwards extending cartridge blocking protrusion (11b) configured to prevent the medicament cartridge (31) from moving proximally until being subjected to a proximally directed force larger than a threshold value, a needle assembly (13) comprising a double-edged needle having a proximally extending needle portion (13a) and a distally extending needle portion (13b), wherein the needle assembly (13) is configured to be assembled with the cartridge holder (11) so that the distally extending needle portion (13b) extends into the cartridge holder (11), and an administration mechanism including a plunger rod (27) configured to be proximally biased, wherein the

Abstract: A stopper being adapted to be fixed in a rear end portion of a syringe is provided. The stopper is reduced in diameter at a fitting portion of a rod portion of a plunger rod so as to have a diameter smaller than an inner diameter of the rear end portion and be insertable into the rear end portion. After insertion, the stopper is increased in diameter and is fixed in the rear end portion so as not to be movable in an axial direction by fitting a first recessed portion on a periphery into a second protruding portion of an inner surface of the rear end portion. The stopper has, on an inner surface, a third protruding portion having an inner diameter smaller than an outer diameter of a gasket support flange of the rod portion in a fixed state.

Abstract: A port fixation device is disclosed and includes a body portion and a plug. The body portion includes a circular portion, a first tab, and a second tab. The circular portion defines an aperture which is configured to allow a surgical access port to extend therethrough. The first tab and the second tab are disposed in mechanical cooperation with the circular portion. Movement of the first tab with respect to the second tab from a first position to a second position causes a diameter of the aperture to change from a first size to a second size. The first size is smaller than the second size, and the first position of the first tab is its rest position. The plug is disposed in mechanical engagement with the body portion, and has sufficient elasticity to remain engaged with the body portion when the first tab is in the first position and in the second position.

Abstract: A rigid hollow tubular adapter releasably attached at a longitudinal nozzle end to a flexible tube during equine nasogastric intubation comprising an annular sleeve having a stationary tubular member and a slidable tubular member. The slidable tubular member is delimited at its ends by the stationary tubular member and a detent member disposed between an equine reflux drainage hole and a longitudinal mouthpiece end. Operator's puffs of airflow through a mouthpiece urges the slidable member to slide toward the detent member closing the equine drainage hole to enable passage of medication into the equine stomach. Equine reflux urges the slidable tubular member to slide toward the stationary tubular member opening the reflux drainage hole to divert equine backflow downwardly through the equine backflow drainage hole preventing passage of equine reflux into the operator's mouth.
