摘要： Apparatus for injecting fluids into the walls of blood vessels, body cavities, and the like, includes a plurality of laterally flexible needles disposed in a catheter for exit either out the distal end of the catheter or the catheter or through corresponding side openings in the catheter. In the latter case, the terminal ends of the needles would be curved laterally, with each terminal end being positioned in a respective side opening so that when the needles were moved forwardly in the catheter, the terminal ends of the needles would move laterally out the respective openings to pierce a vessel or cavity wall adjacent to which the catheter was positioned. Hilts positioned near the terminal ends of the needles serve to control the depth of penetration of the needles.

摘要： A volumetric pump for administering intravenous fluids to a patient comprises a housing having an elongate cavity therein with an open and a closed end. A resilient sheet of material having two branched portions which form a centrally-located aperture is disposed over the open end of the housing. A pump shaft is slidably disposed through the aperture such that one branched portion toward the cavity and the other branched portion extends away from the housing such that a sphincter seal is formed about the shaft. An inlet conduit leading from a fluid source such as an IV bag passes through the housing into the cavity near one end thereof, and an outlet conduit leading to a fluid sink such as a patient passes through the housing from the cavity near the other end thereof. The shaft is driven back and forth in reciprocating motion, inwardly and outwardly of the cavity, to alternately produce a positive pressure forcing fluid out of the outlet conduit to the fluid sink, and a negative pressure forcing fluid from the fluid source through the inlet conduit.

摘要： A volumetric pump valve for pumps for controlling fluid flow, such as in pumps for administering intravenous fluids, comprises a housing formed with first and second cavities, an inlet conduit leading through the housing into the first cavity, an outlet conduit leading through the housing from the second cavity and a passage between the first and second cavities to allow fluid to flow between them. A resilient sealing means is disposed adjacent the passage for selectively sealing the passage to prevent fluid flow between the cavities during low pressure events in the first cavity such that the fluid flows in the direction of the second cavity. A ball disposed on the side of the resilient sealing means opposite the passage is moveable toward the passage to cause the resilient sealing means to selectively seal the passage.
