УСТРОЙСТВО ДЛЯ ВЫРАБОТКИ СВЕРХЧИСТОЙ ВОДЫ

FIELD: chemistry. SUBSTANCE: invention relates to a device for water purification according to the principle of reverse osmosis. The device for the production of superpure water according to the principle of reverse osmosis contains a reverse osmosis filter which is divided into a primary chamber and a secondary chamber, a primary circuit, through which raw water is supplied to the primary chamber and through which a concentrate is discharged from it, and a secondary circuit for the supply of a permeate to at least one consumer, preferably to a dialysis apparatus. A pump is built into a pipeline of the primary circuit, and a valve with a drain is built into the pipeline of the primary circuit concentrate. In or on the primary circuit and/or secondary circuit placed is a device for the registration of organic and/or inorganic deposits, connected with the device of data processing, with an elastic, extendable buffer vessel, adapted for carrying out reverse washing of a membrane with the permeate, being built into the secondary circuit. The device for the registration of organic and/or inorganic deposits is made with a possibility of initiating reverse washing in case of a respective degree of contamination. EFFECT: invention makes it possible to reduce expenditures for the device exploitation due to refusal from periodic cleaning of the membrane and automatic determination of a necessity of the pipeline disinfection. 10 cl, 4 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 536 993 C2 (51) МПК C02F 1/44 (2006.01) B01D 61/12 (2006.01) B01D 65/08 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2012140697/05, 24.09.2012 (24) Дата начала отсчета срока действия патента: 24.09.2012 (72) Автор(ы): ФЁЛЬКЕР Манфред (DE) (73) Патентообладатель(и): ФЁЛЬКЕР Манфред (DE) Приоритет(ы): (30) Конвенционный приоритет: (43) Дата публикации заявки: 27.03.2014 Бюл. № 9 R U 24.09.2011 DE 102011114912.4 (45) Опубликовано: 27. ...

EXTRACORPOREAL FLUID CIRCUIT

A chamber is described for use in an extracorporeal fluid system. The chamber has a bottom entry port and a bottom exit port. A microporous filter at the top of the chamber allows air in the fluid to vent from the chamber. In use, the chamber is filled with saline. Blood is then introduced into the chamber. A layer of saline is above a layer of blood in the chamber. The saline stagnates as the blood flows through the chamber. The saline keeps the blood from contacting the filter and depositing protein on the filter.

SYSTEMS AND METHODS OF MICROFLUIDIC MEMBRANELESS EXCHANGE USING FILTRATION OF EXTRACTION FLUID OUTLET STREAMS

A device, system and method for exchanging components between first and second fluids by direct contact in a microfluidic channel. The fluids flow as thin layers in the channel. One of the fluids is passed through a filter upon exiting the channel and is recycled through a secondary processor which changes the fluid's properties. The recycled fluid is reused for further exchange. The filter excludes blood cells from the recycled fluid and prevents or limits clogging of the filter. The secondary processor removes metabolic waste and water by diafiltration.

FILTRATION FILTER AND PRODUCTION METHOD THEREFOR

Provided is a filtration filter with which a stable opening size during filtration is obtained, and which can be easily regenerated when clogged and used repeatedly. The filtration filter (10) comprises: a substrate stack wherein substrates (11) that have a through hole that penetrates from front to back are stacked; stoppers (15) that define the spacing between the substrates (11); and pillars (16) with a larger thermal expansion coefficient than the stoppers (15). The lengths of the pillars (16) are made to be longer than the lengths of the stoppers (15). The spacing between the substrates (11) at normal temperature is defined at least by the stoppers (15), and the spacing during heating is defined by the thermally expanded pillars (16). The gaps between the substrates (11) form the filtration surface that traps contaminants contained in the liquid that is being treated (A).

DIALYSIS MACHINE AND METHOD OF CONTROLLING IT

A dialysis machine comprises: means for calculating (60) a filtration factor (FF) as a function of the ultrafiltration rate (UFR) and of a plasma flow rate (Q¿p); first comparison means (65) for comparing the filtration factor (FF) with a limit value of admissibility; and signaling means (70) for generating a signal (A) indicating the result of the comparison.

APPARATUS AND METHOD FOR THE AUTOTRANSFUSION OF BLOOD

Autotransfusion apparatus and methods are disclosed for collecting, processing and returning blood to a patient during or after surgery. The processing step of the autotransfusion system comprises sequential rough filtering and filtering of the blood. Filtering is achieved within a single filter housing which includes a first ultrafiltration zone (30) where blood fluids and anticoagulant are separated and removed from red blood cells, a washing zone (71) where washing solution is injected into the remaining concentrated red blood cell solution and a second filtration zone (32) where washing solution, residual blood fluids and anticoagulant are separated and removed from the washed and concentrated red blood cell solution. The filtration includes a rotating disc (46) which creates a shear force upon the blood to prevent clotting and red blood cell build up along the face of filter membranes (48, 50).
