Abstract: The application relates to a device for an intermittent or continuous administration of a therapeutical substance, such as insulin, comprising an injection part and a fluid delivery part (3,4). The fluid delivery part normally comprises a reservoir (4), transferal means e.g. in form of a pump and a house (3), and the injection part normally comprises a base plate (10), a cannula part (1,16) comprising a cannula (9) extending past the proximal side of the base plate and means for fixation of the base plate to the skin of the user. According to the application the device comprises a base plate (10), a cannula part (1, 1b) comprising a body providing a through-going opening leading liquid to a cannula (9) which cannula (9) extends past the proximal side of the base plate (10) and means (21) for fixation of the base plate to the skin of the user wherein a flexible part is arranged in an area between the subcutaneously positioned section of the cannula (9) and the fluid delivery part (3, 4).

Abstract: The application relates to a device for an intermittent or continuous administration of a therapeutical substance, such as insulin, including a base part to which an injection part and a delivery part are fastened. The delivery part includes a reservoir and a pump, and the injection part includes base plate, a cannula part with a body with a through-going opening, and at least one cannula having a proximal end protruding from the lower side of the body and an adhesive portion for fastening the base plate to the skin of the user. The delivery part and the injection part are assembled through a connector having a fluid path leading fluid from the reservoir to the through-going opening in the cannula part.

Abstract: A method for producing a one-piece catheter comprising a hub (3) and a tube-shaped flexible part (4) wherein the tube shaped flexible part (4) has an interior which is divided in two region one being cone-shaped (7-8) and one being cylindrical (5). A one-piece catheter of the above mentioned kind and a mould for moulding such catheter.

Abstract: The application relates to a device for an intermittent or continuous administration of a therapeutical substance, such as insulin, comprising a base part to which an injection part and a delivery part (3,4) are fastened. The delivery part comprises a reservoir and a pump, and the injection part comprises base plate (10), a cannula part (1) with a body with a through-going opening, and at least one cannula having a proximal end protruding from the lower side of the body and means for fastening the base plate (10) to the skin of the user. The device is characterized in that the delivery part (3, 4) and the injection part is assembled through a connector (2) comprising a fluid path leading fluid from the reservoir (4) to the through-going opening in the cannula part (1, 1 b) which fluid path comprises means (7, 8, 8b, 8c) for blocking access to the injection part when the connector (2) is disconnected from the delivery part (3, 4) and/or the injection part.

Abstract: A method for one-piece injection molding of a soft needle catheter having a hub and a tube-shaped flexible part. According to the method, a molten polymer is fed into a mold which includes a core that is used to form the interior of the catheter, the core defining a hub cavity and a tube-shaped cavity. The hub cavity includes a cone-shaped part and a cylindrical part, with the cone-shaped part extending into the tube-shaped cavity. When the polymer is sufficiently cured, the core is removed from the catheter and the catheter is removed from the mold.

Abstract: The invention relates to a connecting element (1) comprising a first body with a through-going axial opening (3) situated in the first body (2) for liquid communication between the first end portion (4) of the first body (2) and the second end portion (5) of the first body (2), said first end portion (4) comprising a cavity (6), and wherein the cavity (6) comprises a female part (9) with a through-going opening (10) and manufactured from a first plastics material and comprising an inner area (35) for mounting of a tube (24) by means of first attachment means (8); and wherein the first body is manufactured from a second plastics material different firm the first plastics material.
