Abstract: An insertion site for a cannula (23) on a skin (8) of a patient is prepared by applying a skin cover unit (1) of the type comprising a window (2) and a wall (3) in extension of the window (2) and connected to the window (2) by a bending region (4) for bending the wall (3) into an angled orientation relatively to the window (2); wherein the win-dow (2) comprises a stabilizing frame (5) and an ultrasonic-transparent flexible sheet (6) within the frame (5). The flexible sheet (6) is glued onto the skin (8) of the patient for ultrasonic investigation of the insertion site through the flexible sheet (6). By bending the bending region (4), the angular orientation of the wall (3) is adjusted into an approximately perpendicular orientation relatively to the window (2) for separating the insertion site from the flexible sheet (6) by the wall (3).

Abstract: A patient interventional drape for covering a person has at least one fenestration. A barrier drape is attached to the patient interventional drape. The barrier drape has at least one sterile cover. The barrier drape is attached to the patient interventional drape next to the at least one fenestration, thereby providing a sterile procedure area at the fenestration and a non-sterile area at the other side of the barrier drape, whereby a non-sterile person can handle procedural devices such as an ultrasonic transducer in the non-sterile area and provide the procedural devices to a healthcare person in the sterile procedure area when needed without any risk of contaminating the sterile procedure area.

Abstract: A cover unit for inserting a puncture device such as a cannula in an anatomical structure such as a vein or an artery and for maintaining said puncture device in said anatomical structure, comprising a flexible film having a glue provided surface, and a removable covering layer to cover said glue provided surface, wherein said cover unit comprises a patient adherent member and a barrier member connected along a connection line, which is arranged close to a puncture site in a patient; said film being made of an ultrasound transparent material; said barrier member being provided with at least one slit or weakening line extending from next to said connection line to a side edge of the cover unit and provided in said film; and said covering layer in the barrier member is removable from the film separately from the corresponding covering layer in the patient adherent member.

Abstract: This invention describes an interventional drape comprising a patient interventional drape for covering a person and with a least one fenestration and a barrier drape attached to said patient interventional drape, where said barrier drape comprises at least one sterile cover where said barrier drape is attached next to said at least one fenestration, thereby providing a sterile procedure area at said fenestration and a non-sterile area at the other side of said barrier drape, whereby a non-sterile person can handle a procedural means such as an ultrasonic transducer in said non-sterile area and provide said procedural means to a healthcare person in said sterile procedure area when needed without any risk of contaminating said sterile procedure area.

Abstract: A breath-actuated inhaler for delivery of a medicament by inhalation from a canister (2) which is compressible to deliver a dose of medicament. The inhaler comprises a housing (1) for holding a canister (2) and including a mouthpiece (5) for delivery of a dose of medicament from a canister (2) held in the housing; and an actuation mechanism (6) for compressing a canister (2) held in the housing (1) in response to inhalation at the mouthpiece (5). The housing includes two separable portions (19, 20). The first housing portion (19) mounts the actuation mechanism (6). The second housing portion (20) houses the mouthpiece (5) and a duct (24) shaped to direct an inhalation flow from the mouthpeice (5) to the first housing portion (19) for triggering the actuation mechanism (6). The duct (24) and the mouthpiece (5) are integrally formed and separable from the second housing portion (20).

Abstract: A dispenser with child protection and a method of operating the dispenser. Friction engagement, engagement using leaf springs or rotatable elements, or engagement directly on e.g. blisters on blister packs are used. Also, biasing against an edge portion and displacement of the holding means edge portion is described in order to remove the engagement. Release mechanisms not visible to children are described as well as the use of multiple independent release mechanisms, which makes release more difficult for children.

Abstract: An inhaler for holding a canister (2) of medicament. The canister (2) has a mount (26) secured thereto mounting an indication member (41) movable slidably from a first state to a second state. A ratchet arrangement (41a, 42) is provided between the mount (26) and the indication member (41) to make the movement irreversible. The inhaler has a catch (49) for moving the indication member from the first state to the second state on removal of the canister (2) from the inhaler. An electrical switch contact (48) detects the state of the indication member (41), thereby providing an indication of whether the canister (2) has been used before. An LCD display is controlled in response to the detection.

Abstract: A fastening device for fixing seismic circular devices is designed with a rigid, split, annular clamp (4) with an open void facing the seismic device (1) for insertion of at least one shock absorbing member (7) in the void. Such a clamp (4) is provided in the region of the device which is most subjected to strain, where a concentric securing ring (8) is also mounted, about which the clamp is fitted with a shock absorbing member (7) on each side of the ring. One more such clamp is provided on the seismic device (1) in order to distribute the load. This arrangement is especially suitable for use in connection with seismic airguns which are to be fixed at predetermined mutual distances in a frame structure (2).

Abstract: A high voltage direct current transmission apparatus having a DC carrying line (L1, K, L2) and including voltage-limiting members (A1, A2) which are arranged so that the limiting level is higher for a line voltage (u.sub.D) of one polarity than for a line voltage of an opposite polarity, and so that for both polarities the limiting level is other than zero.
