  • Patent number: 4684367
    Abstract: An apparatus for ambulatory intravenous delivery of substances to a recipient comprising a container and delivery means for pressurized delivery of the substance. The container communicates with a source of pressurized gas to provide the pressurizing force and is uniquely attachable to the recipient so as to provide portability to the system. The flow rate is controlled by feedback electronics connected to a flow rate meter and a throttle valve. The flow rate meter has a heating resistor in the flow path of the substance and a thermistor to detect a temperature rise in the substance downstream from the resistor. A constriction in the flow tube is disposed between the resistor and thermistor to cause a flat wavefront of temperature increase. The throttle valve is a pin disposed partially within a tube to form an annular gap. The flow rate is adjusted by changing the distance the pin extends into the tube and thereby change the length of the annular gap.

The assembly also includes a rigid, tubular insert which is engageable within the body port and to which the fluid conduit can be attached. A secure and rugged interconnection between the container and the conduit results. When the container and conduit are fabricated from dissimilar materials, the body of the assembly is fabricated from the same materal as the container, and the associated insert is fabricated from the same material as the conduit and adapted for an interference or friction fit within the body port. The same secure and rugged interconnection between the container and conduit is achieved, despite the presence of dissimilar materials.

  • Patent number: 4406655
    Abstract: According to the present system and technique, with the patient lying on his right side, a soap containing enema solution, preferably with a laxative therein, is introduced into the colon through the anal opening via a suitable tube held in the rectum by an inflated balloon (18), preferably from a bag (11) held above the patient, in a volume, usually sufficient to completely fill the colon all the way to the cecum, usually 1500 cc to 3000 cc in a normal adult. Inflation of the balloon can be accurately controlled by using a calibrated syringe (40), acting through a suitable valve containing conduit (21). The balloon and tube can be further secured in place with a limiting means (19) on the tube outside of the patient's anal opening and/or with specially made device (60) designed to squeeze the patient's buttocks together.

  • Patent number: 4403992
    Abstract: For portable use of peritoneal dialysis, a flexible bag of plastic material has two chambers therein, one being a dialysis liquid chamber (42) and substantially larger than a further disinfectant chamber (8); the bag is formed of thermoplastic material, heat-sealed together at seam lines extending thereacross, and sealed into the seam lines are a communication line (16) from the dialysis chamber (42) to the outside, and a branch duct (17) extending from the disinfectant chamber to the communication duct; the respective ducts are closed off at the inside of the chambers, after filling, by releasable closures, such as a ball squeezed into the duct, or a frangible pin which can be broken off by flexing the bag, thus permitting removal of, respectively, dialysis fluid and disinfectant from the respective chambers; used dialysis fluid can be returned into the bag.
