  • Publication number: 20230200852
    Abstract: An apparatus for medical purposes is disclosed. The apparatus includes a medical device configured to be at least partially insertable into body tissue of a user. It also includes an inserter configured for at least partially inserting the medical device into the body tissue. A housing has a removable cap connected thereto, and the removable cap is removed from the housing before insertion of the medical device. A flexible connector connects the removable cap to the housing, the flexible connector being reversibly displaceable from a locking position in which the removable cap is secured to the housing and a releasing position in which the removable cap is released from the housing. A frangible securing element secures the flexible connector into the locking position prior to use. Further, methods for preparing the apparatus and inserting the medical device into the body tissue of the user are disclosed.

  • Publication number: 20020108701
    Abstract: A method of producing a filter insert (1) having folds (2) extending radially, by first pleating a filter material to form an essentially rectangular filter sheet (3) having folds (2) arranged across the longitudinal direction (4), then wrapping the pleated filter sheet (3) around a core (7), and next joining the first fold (8) and last fold (9) of the filter sheet (3) adjacent to one another in the circumferential direction.

  • Patent number: 6143046
    Abstract: A filter cartridge, including a tubular filter element which encloses an interior space on the downstream, clean air side, is joined in the axial direction on one side to a side-face lid, forming a seal. In order to reduce pressure peaks which occur in the filter element on the clean air side, the lid has a diaphragm which is capable of vibrating.

  • Patent number: 5954848
    Abstract: A filter cartridge having pleated filter material, the ends of which are joined together to form a conical tube. At least one band is bonded to the pleated filter material and extends at least partially around the circumference of the material in the area of each of its end sides. The band may be bonded to crease points of the filter material. A method of manufacturing the filter cartridge includes providing the initially strip-shaped, planar filter material with pleats. The pleated strip-shaped filter material is laid out forming an unwound cone-shaped shell. A band is placed onto the crease points of one side and is bonded to the crease points. Subsequently, the filter material is bent to form a conical tube, and the tube is closed upon itself by joining the two ends together.
