Moulded Connection Between Cannula and Delivery Part
A fluid connection for use between a reservoir and a cannula part of a medical device is provided. The fluid connection includes a tube of rigid material. The tube has a first end operably connected to the reservoir and a second end operably connected to the cannula part. The tube is operably attached to a surface plate of the medical device.
1 . A fluid connection for use between a reservoir and a cannula part of a medical device, the fluid connection comprising:
a tube of rigid material, the tube having a first end operably connected to the reservoir and a second end operably connected to the cannula part, the tube being operably attached to a surface plate of the medical device.
2 . A fluid connection according to claim 1 , wherein the fluid connection is fastened to the surface plate by a holding part.
3 . A fluid connection according to claim 1 , wherein the tube comprises metal or plastic.
4 . A fluid connection according to claim 3 , wherein the tube comprises a hollow needle.
5 . A fluid connection according to claim 1 , wherein the tube has a diameter or maximum cross-section less than or equal to about 1 mm.
6 . A fluid connection according to claim 1 , wherein the tube has at least one pointed end protruding from a holding part.
7 . A fluid connection according to claim 6 , wherein the tube has a blunt end.
8 . A fluid connection according to claim 6 , wherein the pointed end of the tube forms a connector needle forming an inlet to a connector part and when pushing a reservoir towards the inlet, the connector needle penetrates a membrane completely covering a first opening of the connector part.
9 . A fluid connection according to any of the claims 1 , wherein the tube comprises a single piece.
10 . A fluid connection according to claim 9 , wherein the tube is bent at an angle greater than 0 degrees in at least one position.
11 . A fluid connection according to claim 10 , wherein the tube is bent in an angle greater than 0 degrees in at least two positions.
12 . A fluid connection according to claim 11 , wherein the angles of the two positions are identical.
13 . A fluid connection according to claim 1 , wherein the tube is stationary in relation to the surface plate after the tube has been attached to the surface plate.
14 . A fluid connection according to claim 1 , wherein the length of a fluid path provided by the connection is maximally about 3 cm.
15 . A fluid connection for use between a reservoir and a cannula part of a medical device, the fluid connection comprising:
a tube of rigid material, the tube having a first end operably connected to the reservoir and a second end operably connected to the cannula part;
a holding part configured to secure at least a portion of the tube therein;
a membrane surrounding the first end of the tube to protect the first end; and
a sealing portion connected to the holding part and surrounding the second end.
16 . The fluid connection according to claim 15 , wherein the tube is bent at an angle greater than 0 degrees in at least one position.
17 . The fluid connection according to claim 15 , wherein the medical device further comprises a surface plate and the fluid connection is operably connected to the surface plate.
18 . The fluid connection according to claim 15 , wherein the first end is pointed to form a connector needle.
19 . The fluid connection according to claim 15 , wherein the holding part comprises a single molded part.
20 . The fluid connection according to claim 15 , further comprising a cover for covering the holding part with the tube secured in the holding part.
