INSERTION DEVICE FOR AN INSERTION HEAD, IN PARTICULAR FOR AN INFUSION SET
First Claim
1. An insertion device for an infusion set, the insertion device comprising a two-part housing, a retainer by which the infusion set can be temporarily held by the device, and a driver including a pretensionable spring for providing the drive energy for an insertion movement of the infusion set, wherein one of the housing parts can be moved relative to the other to engage the infusion set and, after engagement of the infusion set, can be moved again, as a result of which the spring is pretensioned and the insertion device is brought to a ready-to-use state.

Abstract
An insertion device for an infusion set, the insertion device including a two-part housing and a retainer or a retention means by which the infusion set can be temporarily held on the device, and a driver or a drive means including a pretensionable spring for providing the drive energy for an insertion movement of the infusion set, wherein one of the housing parts can be pivoted relative to the other to engage the infusion set and, after engagement of the infusion set, they can be pivoted again, as a result of which the spring is pretensioned and the insertion device is brought to a ready-to-use state. After the insertion movement has been triggered, the infusion set is separated from the device, such that it can execute the greatest part of the insertion movement free of the retainer.

3. An insertion device for an insertion head with at least one infusion cannula and/or at least one puncturing tip for introduction into the body of a patient, comprising:
-
a) a housing having at least one contact face for placing the insertion device onto an application site on the body of the patient for application of the insertion head; b) retention means with which the insertion head that is to be applied is temporarily held on the insertion device; and c) drive means for effecting an insertion movement of the insertion head relative to the contact face in the longitudinal direction of an infusion cannula or puncturing tip of the insertion head from a first position, in which the insertion head is held ready for application by the retention means in such a way that the infusion cannulas and puncturing tips of the insertion head are set back relative to the contact face, to a second position, in which the infusion cannulas and puncturing tips of the insertion head protrude beyond the contact face to permit introduction of the infusion cannulas and puncturing tips into the body of the patient when the insertion movement is executed with the contact face of the insertion device placed on the body, wherein the housing has a first housing part, which carries the retention means and at least some of the at least one contact face, and a second housing part, which is movable relative to the first housing part from an operating position, in which the two housing parts are arranged in a position relative to one another that they adopt during the application of an insertion head with the insertion device, to a loading position, in which the retention means are accessible for correct engagement of the insertion head that is to be applied, wherein, after the insertion head has been engaged into the retention means, the second housing part can be moved back to the operating position, and the insertion device is designed in such a way that, after the insertion head has been engaged into the retention means and the second housing part has been moved back to the operating position, the insertion head is held with the retention means in the first position ready for application such that, at the start of the insertion movement the insertion head is separated from the retention means such that the insertion head executes at least the greatest part of the insertion movement free of the retention means. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A method for applying an insertion head to the body of a patient, the insertion head comprising one of an infusion set, port and/or sensor arrangement and having at least one infusion cannula and/or at least one puncturing tip, said method involving using an insertion device comprising a housing having at least one contact face for placing the insertion device onto an application site on the body of the patient for application of the insertion head, a retention means with which the insertion head that is to be applied is temporarily held on the insertion device, and a drive means for effecting an insertion movement of the insertion head relative to the contact face, in the longitudinal direction of an infusion cannula or puncturing tip of the insertion head, from a first position, in which the insertion head is held ready for application by the retention means such that the infusion cannulas and puncturing tips are set back relative to the contact face, to a second position, in which the infusion cannulas and puncturing tips protrude substantially completely beyond the contact face, to permit introduction of the infusion cannulas and puncturing tips of the insertion head into the body of the patient when the insertion movement is executed with the contact face of the insertion device placed on the body, wherein the housing has a first housing part, which carries the retention means and at least some of the at least one contact face, and a second housing part, which is movable relative to the first housing part, from an operating position, in which the two housing parts are arranged in a position relative to one another that they adopt during the application of an insertion head, to a loading position, in which the retention means are accessible for engagement of the insertion head, wherein, after the insertion head has been engaged by the retention means, the second housing part can be moved back to the operating position, the insertion head then being held by the retention means ready for use, and wherein at the start of the insertion movement, the insertion head is separated from the retention means such that it executes the greatest part of the insertion movement free of the retention means, said method comprising the steps of:
-
a) making ready the insertion device; b) moving the second housing part to the loading position; c) engaging the insertion head with the retention means such that the the insertion head is held by the retention means; d) moving the second housing part from the loading position; e) arranging the insertion device with the contact face on the desired application site on the body of the patient such that the infusion cannulas and puncturing tips can penetrate correctly into the body during the insertion movement; and f) triggering the insertion movement, whereby the insertion head is separated from the retention means at the start of the insertion movement such that the insertion head executes at least the greatest part of the insertion movement free of the retention means. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41)
