Embodiment Construction

[0049] According to the invention, different medical devices can be inserted into the subcutaneous or muscular region of the patient. Such medical devices include, for example, an infusion set or an infusion part of an infusion set, a sensor device with one or more inserted sensors, a port device comprising only a body with a restricted access for replacing Repeated injections with a syringe, or such medical devices include any other device having a penetrating member inserted into the subcutaneous or muscular region of the patient.

[0050] It is an object of the present invention to provide an insertion device which enables a controlled, defined and adjustable insertion of a medical device into a patient. This controlled, defined and adjustable insertion can be achieved by controlling the speed of insertion and optionally by controlling the speed of retraction of components of an insertion device such as those commonly used for inserting The insertion needle of a medical de...

Abstract

The invention concerns an inserter device for inserting a medical device into the subcutaneous or intramuscular area of a patient. More specifically, this invention relates to an inserter device comprising means for providing a controlled and defined acceleration and deceleration of a penetrating member. The inserter device (200, 500) according to the invention comprises a housing (201, 221, 251; 501, 502, 503) encompassing said penetrating member (105, 243), a rotating member (204, 300, 400, 512) and driving means (203, 561) for rotating the rotating member (204, 300, 400, 512) around a rotating axis. The rotating member (204, 300, 400, 512) comprises transformation means (216, 246, 521) transforming the rotational movement into a longitudinal movement of the penetrating member (105, 243) in the direction of insertion and the transformation means (226, 246, 521) comprises controlling means providing a controlled variation of the velocity of the penetrating member (105, 243) in the direction of insertion.

Description

technical field [0001] The present invention relates to an insertion device for inserting a medical device into a subcutaneous or muscular area of ​​a patient. More particularly, the present invention relates to an insertion device comprising a member for providing controlled and defined acceleration and deceleration of a penetrating member. Background technique [0002] Insertion devices, also known as syringes, are commonly used in the medical field to insert medical devices such as infusion sets and the like through the skin of a patient in a semi-automatic manner. [0003] It is well known that most patients, especially children, are afraid of sharp objects such as injection needles and other penetrating devices commonly used in medical procedures and treatments. This fear is often unfounded and may prevent proper medical management. [0004] Another problem with inserting medical devices is the risk of contamination of the penetrating member before or during applicati...
