Abstract

An infusion device including a site and a set for delivery of a substance to a patient. The site can include a cannula that is introduced into a subcutaneous layer of skin of the patient. The set can be coupled to the site by placing the set over the site and moving the set from an unlocked to a locked position. The set can be oriented at multiple rotational orientations with respect to the site, and can be coupled and uncoupled with the site multiple times. Also included is a device for inserting a subcutaneous infusion device into a subcutaneous layer of skin of a patient. Some devices automatically retract a needle used to introduce the cannula. Upon full introduction of the needle and associated cannula of the subcutaneous infusion device into a subcutaneous layer of skin of a patient, the device can move the needle into a retracted state.

Description

technical field [0001] The present invention relates to an infusion device for delivering a substance into a patient. The invention also relates to a device for facilitating the introduction of a cannula of an infusion set into the skin of a patient. Background technique [0002] Infusion sets are used to infuse substances, such as drugs, into the subcutaneous layer of a patient's skin. Typically, an infusion set includes a cannula that is introduced into the skin, and a tube that extends from the infusion set to, for example, an infusion pump to deliver the substance. [0003] In existing designs, it is usually necessary to introduce the cannula of the infusion device into the skin while maintaining the device in a given orientation so that the tubing extends towards the infusion pump. Furthermore, once an infusion set is placed on the skin, it is often not possible to change the orientation of the device and associated tubing, or to remove the tubing from the body withou...
