摘要:
A system and a method for administering a solution (12) from a container (10) to a patient (35) are provided. The container (10) is divided into a solution side (16) and a drain side (18) separated by a tear line (20). The solution side (16) and the drain side (18) are in fluid communication with one another and with a port (28) that connects to the patient (35). The container (10) is separable at the tear line (20) such that contents of a peritoneum cavity of the patient (35) may be drained into the drain side (18) of the container (10). Then, the solution (12) from the solution side (16) of the container (10) may be drained from the container (10) into the patient (35).

A connector assembly and disinfectant system is provided for any system requiring a connection, such as during a peritoneal dialysis procedure. The connector assembly includes a transfer set connector and a disposable connector. The transfer set connector and disposable connector each include a member that join to create a fluid path. The disposable connector contains a housing that includes a ring partially saturated with disinfectant for bathing the transfer set member near the opening of the fluid path when a connection is made. The ring forms an opening through which the transfer set member passes. At disconnection, the transfer set member passes through a section of the ring having wiping properties to wipe the member dry.

A method is provided for creating a plastic component constructed, at least in part, from polychlorotrifluoroethylene, having improved properties. The method creates a component from a composition that has polychlorotrifluoroethylene, heats the component to a temperature that is greater than the melting point of the composition, and rapidly quenches the component in a cold medium.

A connector assembly is provided having a male component (12) and a female component (10) to provide fluid communication between a fluid source and a destination such as a patient. The female component (10) includes a door (28) rotatable about a hinge (30). The door (28) is forced open by a longitudinal member (34) within the male component (12). The door (28) is converted into a position parallel to the length of the female component (10) providing fluid communication between a tubing (36) extending into the female component (10). A sleeve (44) is further provided to permit and to prevent fluid flow through a tubing by rotation of the sleeve (44) resulting in compression and expansion of longitudinal members (46) within the sleeve (44) and thereby the tubing.
摘要:
A non-cross-linked extrudable flame retardant composition and fabricated sheets extruded therefrom are described wherein the composition comprises a blend of polypropylene, a flame retardant and a non-vulcanized copolymer of ethylene and propylene wherein the ratio of polypropylene to copolymer is within the range of from approximately 0.5 to approximately 0.8.
摘要:
A system and method for balancing flows of renal replacement fluid is disclosed. The method uses pressure controls and pressure sensing devices to more precisely meter and balance the flow of fresh dialysate and spent dialysate. The balancing system may use one or two balancing devices, such as a balance tube, a tortuous path, or a balance chamber.
摘要:
A hemodialysis system includes: (i) a dialyzer; (ii) a dialysate source; a dialysate pump; (iii) a dialysate cassette operatively connected to the dialysate pump such that the dialysate pump can pump dialysate through the dialysate cassette when the dialysate cassette is in fluid communication with the dialysate source, the dialysate cassette in fluid communication with the dialyzer; (iv) a blood pump; and (v) a blood cassette separate from the dialysate cassette, the blood cassette operatively connected to the blood pump such that the blood pump can pump blood through the blood cassette, the blood cassette including a housing, the housing including a from-patient tube connector, a to-patient tube connector, a saline/priming tube connector, a to-dialyzer tube connector, a from-dialyzer tube connector, and an internal air separation chamber.
摘要:
A dialysis system includes: a portable device configured to be carried by a patient and to read a marking displayed on a dialysis fluid container, the device obtaining data concerning at least one of a dialysis fluid type and a dialysis fluid volume from the marking; the device defined dialysate dwell time, alert patients for the next exchange and further configured to transfer the data to a computer; and wherein the computer is configured to use the data to track therapy progress of the product.
摘要:
A peritoneal dialysis system includes: a dialysis fluid container associated with an identifier; a reader for reading the identifier; a signal transmitter for communicating data based on the identifier; and a patient transfer set for semi-permanent connection to a patient, the patient transfer set including: (i) a signal receiver for receiving the data sent by the signal transmitter, (ii) an output device for communicating with the patient, and (iii) electronics configured to receive the data and command the output device to communicate with the patient accordingly.
摘要:
A method of modeling a patient's peritoneal dialysis drain phase includes (i) modeling a first segment of a drain phase curve as having a constant flowrate; (ii) modeling a second segment of a drain phase curve as having a decaying exponential flowrate; and (iii) incorporating a switching component into the first and second components so that (a) at a first time the first segment is active and while the second segment is inactive and (b) at a second time the first segment is inactive and while the second segment is active.
