Patent number: 6641177Abstract: A coupling system for coupling flexible tubing between ports includes a port element provided with a barb, and a clamp which secures the tubing over the port element. A first end of the clamp is formed as a plurality of axially extending resilient, yet stiff, fingers having a barb at a tip. The fingers are biased slightly inward toward a center of the channel to define an inner diameter which is smaller than the outer diameter of the tubing. A diameter at the second end of the clamp is larger than a diameter of the tubing to allow for easier installation of the tubing through the channel of the clamp. A diameter of a portion of the channel between the first end and the second end is substantially the same or slightly smaller than the diameter of the tubing such that the clamp snugly grips the tubing without affecting the flow through the tubing. In use, the tubing is inserted through the second end of the clamp, and the tubing is then positioned over the barb of the port element.Type: GrantFiled: August 25, 2000Date of Patent: November 4, 2003Assignee: Precision Design Concepts, LLCInventor: John Pinciaro

Patent number: 5772261Abstract: A method for securing the connection of a medical tube to a port of a fluid transfer instrument. The method provides connections with superior resistance to unexpected disconnection, and thus is particularly beneficial for joining elastic tubes which are implanted within the body for conducting body fluid from one internal location to another or between the body and an external location. The novel method includes inserting a rigid nipple on the port into the lumen of an elastically deformable tube to be joined to the port, placing an initially loose fitting, nonelastically deformable sleeve around the tube on the nipple, and deforming the sleeve radially toward the nipple to clamp the tube between the sleeve and nipple. The extent of deformation is controlled to prevent damaging the tube.A tool for clamping the sleeve to a controlled extent of deformation is also provided.Type: GrantFiled: July 21, 1995Date of Patent: June 30, 1998Assignee: The Nemours FoundationInventor: Gary Magram

Patent number: 5762108Abstract: A hose has an inner wall 1 of blow moulded tube and an outer wall 2 of continuous, spirally formed, corrugated tube. At each end of the hose, the inner wall extends further than the outer wall. The walls are separated by a rigid spacer 3 inserted into the end of the outer tube. The walls are united to a moulded connection member 4. This arrangement has a relatively long spigot 5 which extends from a cavity 6. The inner wall is slid onto the spigot as far as the bottom 8 of the cavity. A radially parting mould is placed around the connection member at a nose 9, within which the cavity extends.

Patent number: 5749603Abstract: A holding device for securing a hose clip in position relative to a pipe connection over which a hose is to be positioned. The holding device has a plurality of holding arms arranged around an axis. The holding arms are connected by a connecting body and each has an internal, radially inwardly directed groove. All grooves are in the same transverse plane of the holding arms and are of the same width as the clip band so that the clip band can be received therein. Preferably, a hose clip in the form of a spring band clip with a clip band having radially outwardly angled clamping jaws is used. A U-shaped clamp, which holds the clamping jaws together when the spring band clip is in an open position, may be connected to the connecting body by a connecting member which permits the clamp to pivot away from the clamping jaws but which prevents the clamp from being separated and thereby becoming lost.Type: GrantFiled: May 16, 1996Date of Patent: May 12, 1998Assignee: Rasmussen GmbHInventor: Stephan Mann

Patent number: 5743569Abstract: A frangible region is provided around at least one end of the outer connector part or cover of a hose and connector assembly, whereby a significant portion of such outer cover can be easily removed from the frangible connection to its end. This frees the end of the underlying hose to be removed from the inner connector part, a new hose part engaged over the exposed portion of the inner connector part, and a conventional clamp used to secure the new hose piece in place on the inner connector part. The outer jacket can be comprised of a plurality of bands, each band molded in place around a hose end, instead of a single piece outer jacket. The frangible region is created in the original molding process, and can, if desired, be formed on more than one of the ends of the outer molded connector part or the bands.Type: GrantFiled: October 15, 1996Date of Patent: April 28, 1998Assignee: Cooper Tire & Rubber CompanyInventors: Dennis J.

Patent number: 5735554Abstract: A tube conduit connection and method of producing the same, whereby an end of a pipe made of polyolefin is cold-deformed, i.e. at the ambient temperature, by means of a spreading mandrel. After the spreading mandrel is removed, the enlarged pipe end and a desired connecting piece or the end of another pipe are plugged onto each other. The polyolefin pipe end is then deformed back to the original shape and forms by self-redeformation a solid and gas-tight connection with the connecting piece or the end of the other pipe.Type: GrantFiled: August 26, 1996Date of Patent: April 7, 1998Inventor: Fredrich Imgam

Patent number: 5681061Abstract: Quick-connect couplings having a sleeve with a tubular tube support mounted therein, an internal O-ring, an external O-ring and a collet are configured to retain a tube on the tubular tube support by engaging the tube with the collet. In accordance with one embodiment of the invention, the tubular tube support is retained in the sleeve by engagement with a first internal annual shoulder in the sleeve. The interior O-ring positioned against a second annular shoulder within the sleeve to seal against the tube. The collet resiliently fits within the sleeve to retain the tubular tube support and internal O-ring in place prior to assembly. An external groove is provided in the sleeve for receiving an external O-ring to seal with the bore which receives the coupling. In accordance with another embodiment of the invention, the tubular tube support is staked to a first end of the sleeve by a radially extending flange. The internal O-ring is disposed between the end of the collet and the radially extending flange.Type: GrantFiled: October 27, 1995Date of Patent: October 28, 1997Assignee: Dana CorporationInventor: Darwin C. Olson

Patent number: 5620209Abstract: A device for clamping a hose end section that is fitted onto a pipe end section includes a hose clamp surrounding a hose end section. The hose clamp has overlapping end sections, each of which has an approximately radially outwardly extending tensioning jaw. A securing ring is fixed to the hose end section and has a radial projection. The securing ring surrounds the hose end section and is disposed between the hose end and the hose clamp. The securing ring is joined to the hose clamp in an area diametrically opposite to the area of overlap of the end sections of the hose clamp. The securing ring has a recess disposed in a radial projection. An approximately U-shaped clip has a cross-piece and a pair of legs depending from the cross-piece. The U-shaped clip is disposed such that, in the tensioned state, the legs of the clip overlap the tensioning jaws of each of the end sections. The U-shaped clip has a hook depending from the cross-piece that is radially engaged in the recess.Type: GrantFiled: February 5, 1996Date of Patent: April 15, 1997Assignee: Rasmussen GmbHInventor: Heinz Sauer
