4289 results about "Dialysis" patented technology

In medicine, dialysis (from Greek διάλυσις, Dialysis, "dissolution"; from διά, dia, "through", and λύσις, lysis, "loosening or splitting") is the process of removing excess water, solutes, and toxins from the blood in people whose kidneys can no longer perform these functions naturally. This is referred to as renal replacement therapy.

Method for treating amyloid disease

Disclosed herein are methods for treating amyloid disease in humans by clearing amyloid peptides from one or more bodily fluids such as, e.g., blood, of a patient. In particular, the methods are based on the administration capable of binding to amyloid-beta (Aβ) or on dialysis of blood or plasma exchange in order to remove Aβ peptides from the blood circulation, and / or brain or other affected organs.

Disinfection of dead-ended lines in medical instruments

A method of disinfection of a dead-ended fluid line in a medical instrument such as a dialysis machine is described. The method comprises introducing a heated fluid into the fluid line, allowing the fluid to remain in the line for an experimentally determined optimal dwell period, removing the fluid from the fluid line, and then repeating the cycle for a time period sufficient to achieve a disinfection of the fluid line. The optimum dwell period and frequency for exchanging the heated fluid is determined so that the heated fluid is left resident in the line to exert a cidal effect but not so long that the it cools to the point of being ineffective, nor changed so frequently that that the time spent with no hot water resident in the line begins to detract (e.g., unduly prolong) the disinfection process. A representative cycle is introducing water at a temperature of about 85 degrees C, allowing it to reside in the fluid line for about 10 seconds, withdrawing the water, and then reintroducing water at 85 degrees C. The process continues for 1-2 hours. Variation from the representative cycle will be expected based on parameters such as the degree to which disinfection is to be achieved, the length and diameter of the fluid line, the temperature of the fluid, the ambient temperature, the presence of elements in the fluid line that contribute to heat loss, the material used for fluid line tubing, and whether the fluid comprises water or a disinfection solution such as a dilute citric acid solution. The optimum dwell period and frequency of the cycles can be determined experimentally from the teachings described herein.

Apparatus and method for producing purified water having microbiological purity

A process is provided to produce water that will meet the specifications of the United States Pharmacopeia Inc. for Purified Water and Water for Injection, and water for dialysis as circumscribed by the American Association for Advancement of Medical Instrumentation (AAMI). The system has no storage tanks where stagnant water will be fouled by biofilm colonizing the tank surface. Water is circulated throughout the purification system and drawn as required, on demand. The water is purified and used immediately or recycled and repurified to ensure quality. Sanitation of the purification system, maintaining microbiological purity and cleaning is done by controlling the pH so that it is normally acidic by maintaining a high carbon dioxide concentration in solution, the carbon dioxide being allowed to pass into the permeate from a reverse osmosis membrane assembly used to purify the water.

Medication thermal energy water circulating blanket

The invention discloses a medication thermal energy water circulating blanket which comprises a liquid heat radiation circulating loop structure formed by connecting a dialysis macromolecule energy pipe, a constant-temperature furnace, a minitype mute water pump and the like, the dialysis macromolecule energy pipes is evenly arranged on a cotton blanket body to cool the cotton blank body. According to the medication thermal energy water circulating blanket, needed medicinal materials only need to be placed on a filter screen in the constant-temperature furnace, nutrition ingredients of the medicinal materials are absorbed by water, agentia is pumped to the dialysis macromolecule energy pipes to circulate, the dialysis macromolecule energy pipes distribute the nutrition ingredients of the agentia to a bed blanket slowly to be absorbed by a human body through pores of the human body at this moment, and therefore people can be moisturized by the water and can obtain the nutrition effect of the medicinal materials in sleep, people can feel warm and comfortable, and can maintain beauty and keep young, and the special effect of preventing diseases can be achieved. Heating, circulating and heat preservation in the whole process are automatically controlled, the medication thermal energy water circulating blanket is simple in structure, low in cost, convenient to use and good in market prospect and has good market prospects, and social benefits and economic benefits are considerable.
