Abstract:
A medical fluid machine, such as a dialysis machine, includes a pump (100) that pumps a medical fluid and sterile water or other disinfecting liquid, such as ozonated water, for flushing and reconditioning the medical fluid machine. The machine may also include a heater (38) that heats the medical fluid or disinfecting solution in order to kill bacteria and other microorganisms that may contaminate the machine after use. Disinfecting the machine, and a disposable kit (50) used with the machine, may allow re-use of the disposable within a reasonable amount of time after completion of the disinfecting procedure. Dialysate treated with ultra-violet light or water with low concentrations of ozone also helps make the disposable kits suitable for resuse.
Abstract:
A peritoneal dialysis machine includes an enclosure; dialysate pump located within the enclosure; a graphical user interface connected to the enclosure and configured to display a parameter associated with the dialysate pump; and a projector configured to project the parameter onto a surface external from the enclosure so as to allow a patient to readily view the parameter.
Abstract:
The present invention provides a polymer blend for fabricating a laser-weldable article having a first component of a material not thermally responsive to a laser beam and selected from the group consisting of polyolefins, ethylene and lower alkyl acrylate copolymers, ethylene and lower alkyl substituted alkyl acrylate copolymers, ethylene vinyl acetate copolymers, polybutadienes, polyesters, polyamides, and styrene and hydrocarbon copolymers; a second component of a laser responsive material having low solubility in an aqueous medium and present in an amount by weight of from about 20 ppm to about 2000 ppm; and the blend being sufficiently thermally responsive to exposure to a laser beam having a wavelength within a range of wavelengths from about 700 nm to about 1500 nm to at melt upon exposure to the laser beam for a short period of time.
Abstract:
Una máquina de suministro de fluido, tal como una máquina de diálisis o hemodiálisis peritoneal, incluye un surtidor o casete (3) que bombea un fluido médico para diálisis u otros tratamientos para pacientes. La maquina incluye y utiliza un dispositivo de auto-conexión (5) para conectar recipientes de liquido, tales como bolsas de fluido de diálisis o fluidos de medicamento, a la maquina, mientras se mantiene la esterilidad de la conexión. El dispositivo de auto-conexión remueve la tapa de la tubería de la bolsa de fluido y perfora la membrana de sellado en la tubería. Eso facilita más que los pacientes reciban el tratamiento, especialmente en tratamiento casero. Otras modalidades son útiles para el suministro de otros líquidos a partir de otros tipos de máquinas de suministro o de bombeo.
