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.
This application claims the benefit of U.S. Provisional Application No. 61/028,262, filed Feb. 13, 2008, and Danish Patent Application No. PA 2008 00203, filed Feb. 13, 2008. These references are incorporated by reference herein in their entirety.
One aspect of the invention relates to a device for continuous administration of a therapeutically working substance, such as insulin, comprising a base part to which an injection part and a delivery part can be fastened. A delivery part normally comprises a reservoir and e.g. a pump, and the injection part comprises a body with a through-going opening, and at least one cannula having a proximal end protruding from the lower side of the body. One aspect of the invention comprises a fluid connection formed between a reservoir and a cannula part which fluid connection normally is attached unreleasably to the base plate and has the form of a tube made of a rigid material.
WO 2007/071258 describes a medical device for delivering fluid comprising an injection part and a fluid delivery part where the fluid delivery part and the injection part can be separated and rejoined. The fluid delivery part comprises a reservoir, means for transport of liquid e.g. in form of a pump and a housing in which the active units of the delivery part is placed. The injection part comprises: a base plate, a cannula part comprising a body with a through going opening provided with a cannula extending past the proximal side of the base plate and means for fixation of the base plate to the skin of the user e.g. in the form of a mounting pad. The delivery part and the injection part is assembled through a connector comprising a fluid path leading fluid from the reservoir to the through-going opening in the cannula part which fluid path comprises means for blocking access to the injection part when the connector is disconnected from the delivery part and/or the injection part. FIG. 20-24 in this document illustrates an embodiment where the connector is constructed of a molded body fastened unreleasably to a base plate and provided with an interior compartment to which access is protected by a septum. The septum can be penetrated by a connector needle belonging to the delivery part when the delivery part is fastened to the base plate. From the lower part of the interior compartment of the connector, an opening 5 a allows fluid to enter into a flexible tube and pass onto the cannula part 9. The flexible tube is connected to the first part of the injection part and when the second part 1 b of the injection part is positioned in the first part 1 a a fluid path is created from the flexible tube 5 to the cannula 9.
An object of the invention is to provide a fluid connection between a reservoir and a cannula part which fluid connection is attached to a surface plate and has the form of a tube made of a rigid material. That the fluid connection is placed between the reservoir and the cannula part means that the fluid connection does not form part of either the reservoir or the cannula part e.g. the tube does not comprise the actual cannula which penetrates the patients skin. The tube can be releasably or unreleasably attached to the surface plate.
According to one embodiment the tube is bent at an angle >0 degrees in at least one position. According to this embodiment the tube can be bent in an angle >0 degrees in at least two positions. Normally the angle will be larger than 45 degrees and according to one embodiment the angle is around 90 degrees. Further the angles of the two positions will normally be identical.
FIG. 9 shows a second embodiment of a cannula.
FIGS. 10A, B and C show one embodiment of a connection part according to the invention including the internal parts.
FIGS. 12A and 12B show a second embodiment of a connection according to the invention including the internal parts.
FIGS. 13A and 13B show a third embodiment of a connection according to the invention including the internal parts.
In order to secure a fluid tight connection between the inlet opening 13 in the connection part 3 and the reservoir 6, a bubble shaped membrane 17 has been positioned in the first opening 13. The membrane 17 completely covers the inlet opening 13 (which according to this embodiment could be understood as being the open end of a connector needle 19) and prevents contamination of the connection part 3. When the reservoir 6 is pressed towards the connection part 3, the connector needle 19 will penetrate the membrane 17 and provide a completely fluid tight transferal of fluid between the connection part 3 and the reservoir 6.
FIG. 8 shows an enlargement of the cannula part 7 shown in FIG. 1. This embodiment comprises a body 24 provided a cannula 22 and with a protruding front 25 having a flat surface. The surface of the cannula part 7 having an opening need not be flat; it can actually have any desired shape as long as it is possible to create a corresponding surface on the connection part 3 facing the cannula part 7. In one embodiment the front 25 is inclined in such a way that the cross-section at the upper i.e. distal end is larger than the cross-section at the proximal end, i.e. the end closest to the patient after insertion, of the front. The front 25 is provided with an opening 20 through which liquid can exit or enter the cannula part 7. The body 24 is further provided with a top opening 21 which opening can be covered with a self closing membrane. The opening 21 need some kind of entrance protection as it is facing an outer surface which is in contact with the surroundings. The top opening 21 is primarily used when inserting the cannula part 7 if the cannula 22 is a soft cannula. That the cannula 22 is soft means that is made of a relatively soft material which can not penetrate the patients skin, in this case it is necessary to use a pointy insertion needle of a relatively hard material when inserting the cannula and this pointy needle can be inserted through the top opening 21, pass through an inner hollow in the body 24 of the cannula part and further pass through the full length of the cannula 22 in such a way that the pointy end of the insertion needle stick out of the open end of the hollow cannula 22. After insertion i.e. after the cannula 22 has been placed sub- or transcutaneous in the patient, then the insertion needle is retracted and the cannula 22 is left inside the patient.
FIG. 9 shows an enlargement of a second embodiment a cannula part 7. This embodiment also comprises a body 24 provided with a cannula 22 and with a protruding front 25 having a flat surface provided with an opening 20 but according to this embodiment the protruding front 25 is inclined in such a way that the pressure between the opening 20 and the sealing 18 around the second opening 12 of the connection part 3 is increased. The inclination of the front 25 is defined by the angle d between the centre line c of the cannula 22 and a line parallel to the surface around the opening 20. The angle d will be larger than 0° and smaller than 90°, normally d ∈ ]0°, 30°] depending on the diameter or the protrusion of the sealing 18 or [60°, 90°[. The distance d1 between at the distal end of the surface of the protruding part 25, i.e. the end of the cannula part 7 which is furthest away from the patient after insertion, and the centre c of the cannula part 7 is larger than the distance d2 between the surface of the protruding part 25 at the proximal end, i.e. the end closest to the patient after insertion, and the centre c of the cannula part 7. Normally the distance d2 will be so small that the proximal end of the protruding front 25 does not touch the sealing 18 of the connection part 3 during insertion.
In one embodiment (not shown) the angle d is close to about 90° i.e. d=90°, such an embodiment would in a drawing corresponding to FIGS. 9A and 9B appear to have an upward opening 12 of the connection part 3 fitting to a downward opening 20 of the cannula part 7. This means that the force pushing the cannula part 7 toward the sealing 18 will be close to perpendicular to the contact surface of the sealing 18 and this will prevent that the sealing is distorted during insertion of the cannula part 7 by the cannula part 7 sliding along the sealing 18.
In another embodiment (shown in FIG. 8) d is about 0° as the protruding front 25 and the centre line c are parallel. According to this embodiment the cannula part 7 will be in sliding contact with the protruding sealing 18 which can cause the sealing to be distorted.
FIGS. 10A-C show one embodiment of a connection part 3. FIG. 10A show the embodiment of the connection part 3 in an exploded view where the internal holding parts 61 for a tube 60 providing a fluid path is shown. FIG. 10B shows a cut through the internal holding part 61 according to which it is possible to the position of the tube 60. FIG. 10C shows an enlargement of the encircled part of FIG. 10A.
FIG. 10B shows an enlargement of the internal parts of the connection part 3. The holding parts 61 comprise a single molded part which is providing a stable embedment of the tube 60. The open end of the tube 60 opens into a space surrounded by the sealing 18. The closed end of the tube 60 is completely surrounded by a soft membrane. “Completely surrounded” means that the there is no free access to the surroundings, “soft membrane” means that the membrane can be penetrated by a needle, especially the connector needle 19 which is provided by the end of the tube 60 and which is embedded inside the soft membrane. The end of the tube 60 which constitutes the connector needle 19 is in this embodiment not actually in touch with the surrounding membrane 17. The connector needle 19 is surrounded by air, and the internal space surrounding the connector needle 19 has a cylindrical or conical shape i.e. a circular cross-section. The walls of the membrane 17 will deform by bending inwards or outwards when the length of the membrane is reduced as a result of the applied pressure.
The tube 60 can be constituted either by a straight or by a bent piece of pipe-shaped rigid material such as steel or a hard plastic material, and the tube 60 is held by a holding part 61 which holding part 61 according to this embodiment also provides for a cover surface which cover surface is constituted by the outer side of the holding part 61 shown in FIG. 12A. If the tube 60 is a straight piece of material the second end of the tube 60 which is the end connected to the cannula part 7, opens into a room formed in the holding part 61 and having an inlet/outlet to the cannula part 7 through a small opening 18 c in the fastening means for the sealing 18 a. If the tube 60 is a bent piece of material the second end of the tube 60 is bent in about a 90 degree angle through the small opening 18 c which is formed in the fastening means 18 a. The fastening means 18 a provide the means for fastening of the sealing 18 to the holding part 61. The fastening means 18 a are provided with a large opening 18 b which opening provides a connecting room between the tube 60 and the connector needle 19 when the holding part 61, the fastening means 18 a and a separate sealing part 61 b are pressed together. The connecting room provides a fluid connection between the connector needle 19 and the tube 60 as the room can fill with fluid entering from the connector needle 19 where after fluid can exit the connecting room by exciting through the tube 60. The side of the fastening means 61 a for the membrane which is turned toward the fastening means 18 a for the sealing can be provided with a sealing in order to keep the connecting room fluid tight.
According to the embodiment of FIG. 13A-B, the tube 60 is bent at two positions. This is suitable according to this embodiment as the reservoir 6 and the cannula part 7 are mounted on the same side relative to the holding parts 61. The angles of both the bends are about 90 degrees, if the tube 60 is to be positioned in a one piece holding parts 61 by pushing, then the two legs provided by these two bends should have the same angle in relation to the connecting tube piece between the two bends but the angles need not be 90 degrees. If the reservoir 6 and the cannula part 7 are positioned different in relation to each other the tube 60 might be bend only once e.g. in the situation where the cannula part 7 is positioned close to the edge of the surface plate 1 and has the front provided with the opening 20 turned toward the first and only bending of the tube 60.
