摘要： A syringe device and injector system including a vent for relieving a vacuum within a syringe is provided. Embodiments provide a syringe device including a reservoir having a sidewall. The reservoir includes a dispensing distal end a proximal end. The syringe device also includes a piston in movable sealing engagement with the sidewall. Furthermore, the sidewall defines a vent extending from the proximal end of the reservoir. The vent is configured to interrupt the sealing engagement between the piston and the sidewall so as to allow a gas to enter the reservoir through the proximal aperture and past the piston member as the piston member is moved from the distal end to the proximal end of the tubular aperture.

摘要： The invention includes a device, kit, and system capable of manually distending a subject's body cavity. In one embodiment, the invention includes a distention media reservoir (10), insertable member (20) for insertion into a body cavity, and a manually operated pumping member (12) capable of displacing distention media from the reservoir and into a body cavity. In some embodiments, the distention media reservoir may be air or CO2. In one embodiment, the invention is available in the form of a kit. In another embodiment, the devices include a reusable portion and a consumable portion. The reusable portion may include the media distention reservoir and pumping member, the consumable portion includes the insertable member, and may also include a barrier for preventing effluent from contaminating the reusable. In other embodiments, the device is adapted to function as a distention media booster pump that may be used in conjunction with an electro-pneumatic insufflation system.
