Publication number: 20220146023Abstract: A system of connecting two flexible tubes together using the rolled back ends of the tubs to create abutment surfaces which when urged together for a fluid-tight seal. The rolled back ends are supported on tube supports including a spigot extending along the outside of the tube and over which the rolled ends are supported. Urging two rolled backed ends together creates a fluid tight seal. This may be achieved by attaching flanges to the rolled back ends and using standing clamping means. Alternatively, other types of clamping means can be used.Type: ApplicationFiled: March 11, 2020Publication date: May 12, 2022Applicant: Bio Optimal LimitedInventor: Roy Peter Maunder

Patent number: 9115836Abstract: A retaining clamp for retaining a tube on a barbed connector. The clamp includes a collet, having a first portion sized to fit over a tube on a barbed connector, and a plurality of fingers extending from the first portion for fitting behind the barb of a connector, the fingers having inward extensions at their distal ends for urging the tube against the connector behind the barb. The clamp also includes a sleeve, sized to fit over the collet and to urge the fingers on the collet inwards to retain the tube on the connector. The collet and sleeve are held in position with a ratchet. In addition, one of the sleeve or the collet includes an inward projection for urging the tube against the end of the barb on the barbed connector in use.Type: GrantFiled: October 19, 2010Date of Patent: August 25, 2015Assignee: BioPure Technology LimitedInventor: Roy Peter Maunder

Patent number: 9044845Abstract: Apparatus to insert a spigot into a flexible tube comprises a support for holding and advancing a spigot, actuated by a motor, and a grip for holding a flexible tube, its opening and closing controlled by a motor. On operation of the apparatus, the support is advanced to urge the spigot into the flexible tube. To prevent catching or snagging of the tube on the spigot preventing insertion, after forward motion of the spigot, the jaws are opened, and the spigot is retreated a short distance, the jaws are closed and the spigot is advanced again. This cycle is then repeated until the spigot is fully within the tube. The jaws have a front section and a separate back section, mounted against a resistance, to hold the tube. The front section will be urged back against the resistance on insertion of the spigot, which will not reach the back section.Type: GrantFiled: October 10, 2012Date of Patent: June 2, 2015Inventor: Roy Peter Maunder

Patent number: 8756780Abstract: Apparatus to connect a flexible tube to a spigot on bio-disposable systems. The apparatus comprises a support for a spigot and jaws for gripping and holding a flexible tube. The jaws open and close for insertion of the flexible tube either under manual or pneumatic force. The jaws also include a front section that is openable against a resistance. In use, the end of the spigot is place inside the end of the flexible tube, the spigot is then positioned on the support, and the tube clamped into the jaws. Either on manual or pneumatic action, the spigot is advanced into the flexible tube within the jaws. The front section of the jaw opening slightly to accommodate the spigot, while the back section of the jaw holds the tube firmly in position.Type: GrantFiled: January 24, 2011Date of Patent: June 24, 2014Assignee: BioPure Technology LimitedInventor: Roy Peter Maunder

Publication number: 20140082898Abstract: A clamp having a pair of clamping tangs hinged together at one end and connectable together at the other end by means of a screw and nut. The screw has a main threaded section for tightening of the nut onto a seat on a tang. It also has an unthreaded section of shaft, over which the nut can move freely. At the distal end of the screw is a further short threaded section, to retain the nut on the screw, when disconnected from the main threaded section. The nut can be removed totally from the screw by engaging with the short threaded section, and rotating to disengage. The to other end of one tang having a clevis into which a crossbar on the screw connects, the other tang also having a clevis into which the screw pivotally fits, the upper surface of the clevis providing a seat for the nut.Type: ApplicationFiled: September 19, 2013Publication date: March 27, 2014Applicant: BioPure Technology LimitedInventor: Roy Peter Maunder

Patent number: 7677612Abstract: A clamp for connecting flanged tubes comprising a pair of tangs having a tampered groove around their insides to engage the flanges. One of the tangs is provided with a pivotally connected screw, which passes through an aperture in one end. A nut attached to the screw holds the tangs in position. To prevent rotation of the tang about the screw, the lower shaft of the screw is provided in a non-circular shape, with the aperture in the tang being provided in mating conformity.Type: GrantFiled: September 25, 2008Date of Patent: March 16, 2010Assignee: BioPure Technology Ltd.Inventor: Roy Peter Maunder

Patent number: 7370889Abstract: A connector for a tube comprises a hollow spigot and an outer securing member for capturing a tube therebetween. The hollow spigot includes an internal bore matched to that of the tube, a tapered end with a frusto-conical length and its small diameter at its distal end and a parallel length inwards of the tapered end, with a diameter less than the maximum tapered diameter and an annular rib inwards of the parallel length to provide an end stop for the tube when fitted onto the spigot. The outer securing member includes an internal tapered bore matched to the frusto-conical length and of respectively increased diameter to accommodate the tube therebetween and at least one latch formation spaced from the member's large tapered end for engaging behind the annular rib.Type: GrantFiled: February 7, 2005Date of Patent: May 13, 2008Assignee: Bio Pure Technology LimitedInventors: Roy Peter Maunder, David Whitmore Hilton

Patent number: 6708377Abstract: A clamp has two injection moulded tangs 1, 2 hinges together by a pin 3 and held closed by a wing nut 4 and a screw 5 having a cross-head 6. The tangs each have a tapered groove 7 running around inside them. In use, this groove engages flanges F on tubes T with a seal S therebetween to hold the tubes in sealing relationship with each other. The one tang 2 has a clevis 10 defined by two lugs 11. Each has an overhung recess 12 into which the cross-head 6 of the screw clips. A crossbar 14 connects the lugs remote from their tang, whereby the screw is limited in its angular displacement about the recesses 12, as shown in FIG. 3. The crossbar also stabilises the lugs against relative displacement under load when the nut is tightened. The other tang 1 has a part conical formation 21 on lugs 22 defining a clevis 23 similar to clevis 10. The nut has a complementary conical recess 24. Engagement of the formation 21 in the recess 24 restrains the lugs from separating under load as the nut is tightened.Type: GrantFiled: April 26, 2002Date of Patent: March 23, 2004Assignee: Bio Pure Technology LtdInventor: Roy Peter Maunder
