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.

Claims

1. A device for subcutaneously introducing a liquid to a body of a patient, comprising:

a first member with a connection port for coupling of a conduit for supplying a liquid; and

a second member with a cannula protruding therefrom for introduction in a body of a patient,

wherein the first member and the second member are configured such that they can be rotated and connected relative to one another in a plurality of positions and in every relative position be fluidly coupled for introducing a liquid from the conduit to the cannula, and

wherein the connection port is designed such that the coupling and uncoupling of the conduit takes place in a direction transverse to a longitudinal axis of the cannula.

2. The device of claim 1, wherein the second member comprises a contact surface for contacting the body of the patient.

3. The device of claim 2, wherein the contact surface comprises an adhesive layer for coupling the first member to skin of the patient.

4. The device of claim 1, wherein the plurality of positions is arranged throughout 360 degrees around the longitudinal axis of the cannula.

5. The device of claim 1, wherein the first member and the second member can be rotated relative to one another about an axis of rotation parallel to the longitudinal axis of the cannula.

6. The device of claim 5, further comprising at least one locking element to selectively secure the first member and the second member relative to one another to prevent relative rotation.

7. The device of claim 6, wherein the at least one locking element is configured to selectively secure the first member and the second member relative to one another in at least one predetermined position.
