The subject matter of the invention is a filter element (13) for insertion into a vacuum cleaner, with an upper side (14), a lower side (15) which lies opposite the upper side (14), a filter body (19) which extends from the upper side (14) to the lower side (15) and which forms a wall (26) of a clean air space which is situated between the upper side and the lower side, and with a conveying opening (17) which is arranged on the upper side (14), opens into the clean air space, and through which an air flow which is driven by way of the vacuum cleaner can be conveyed. According to the invention, a deflecting surface (20) which extends in the direction of the lower side (15) is arranged in the clean air space below the conveying opening (17), which deflecting surface (20) is configured to deflect an air flow which is introduced through the conveying opening (17) in the direction of the wall (26) of the clean air space. The filter element (13) according to the invention can be relieved of filter cakes in a simple and effective way.

A blood clot removal device for removing blood clots from the vascular system of a patient is implantable in the patient's body. The blood clot removal device comprises a blood flow passageway, a filter provided in the blood flow passageway for filtering blood clots, and a cleaning device for cleaning the filter. By means of such blood clot removal device and system, the risk of blood clots reaching sensitive areas of the patient's body, such as the brain, is reduced.

A filtering device for removing particles from a fluid of a patient is provided. The filtering device being implantable in the patient's body and comprising a cassette comprising a revolving member, said revolving member having at least two segments each holding a respective filter. The device further comprises a tube forming a fluid passageway through one of the filters in said cassette, wherein the cassette is adapted to, upon revolution of the revolving cylinder, change the filter positioned in the fluid passageway from a first one of said filters to a second one of said filters, thereby allowing particles present on the first filter to be moved away from the fluid passageway, while at the same time changing the filter positioned in the fluid passageway.

This document discloses a valve comprising a main valve closure body, arranged on a low pressure side of the valve and moveable to open towards the low pressure side, a control body, fixedly connected to the main valve closure body, such that a position of the main valve closure body is fixed relative to a position of the control body, a control chamber, partially defined by the control body, whereby a volume of the control chamber is variable in relation to the position of the control body, and a control fluid connector for controlling a pressure in the control chamber. The document also discloses use of the valve in a separator for separating dust and debris from an airflow, a separator comprising such a valve and a method of operating a separator.

A blood clot removal device for removing blood clots from the vascular system of a patient is implantable in the patient's body. The blood clot removal device comprises a blood flow passageway to be connected to the patient's vascular system to allow circulation of the patient's blood through the blood flow passageway, a filter provided in the blood flow passageway for collecting blood clots occurring in the blood flowing through the blood flow passageway, and a cleaning device for moving blood clots collected by the filter out of the blood flow passageway. By means of such blood clot removal device, the risk of blood clots reaching sensitive areas of the patient's body, such as the brain, is reduced.

Provided is an operation method for a coating exhaust treatment system that includes a filter configured to filter discharged air discharged from a coating chamber in which a coating object is spray-coated and collect overspray coating material included in the discharged air, and a powder dispersal means configured to disperse powder for forming a filter covering layer in the discharged air and form a filter covering layer made of a layer of the accumulated powder on a surface on the filter as the discharged air passes through the filter, the method including, when the number of repetitions of a first operation reaches a set number while the first operation and a second operation are being repeatedly carried out alternatingly, discarding coating material-containing powder and supplying fresh powder to a first supply tank, and when the number of repetitions of the second operation reaches the set number, discarding the coating material-containing powder and supplying the fresh powder to the second supply tank.

A method for removing particles from a bodily fluid in a patient with a filtering device, the filtering device being implantable in the patient's body and the method comprising the steps: pass bodily fluid of the patient through a tube forming a main fluid, filtering the bodily fluid passing through said main fluid passageway with a filter connected to the tube, collecting particles in the bodily fluid to be removed passing through the tube, and cleaning the filter with a filter cleaning device by removing particles collected by the filter out of the fluid passageway.

A method for controlling and implanting an implantable drainage device is provided. The device is adapted to move body fluid from one part of the body of a patient to another part of the body. The invention also extends to a filter adapted to filter particles from a drained fluid.

The present invention relates to an implantable cassette for holding filters. The cassette is provided with a revolving compartment having a plurality of segments. Each segment is for holding a filter for filtering blood. Also provided is attachment means for attaching the cassette to a blood flow passageway to thereby allow blood to flow through a first segment of the revolving compartment. An operation device for revolving the revolving compartment, to thereby move the first segment out of the blood flow passageway, is also provided.
