Patent number: 11246977Abstract: A fluid delivery system (1) includes a reservoir (7) for storing a fluid, a pumping chamber (8) and an actuator (20). The pumping chamber (8) has a volume, an inlet valve (48) providing selective fluid communication between the pumping chamber volume and the reservoir, an outlet valve (49), and a membrane (47) the displacement of which changes the pumping chamber volume. The actuator (20) moves a drive member (21) in reciprocating motion. The actuator (20) is disposed in a housing (9) having an aperture (36) from which the drive member projects. The reservoir (7) and the pumping chamber (8) are arranged in a cartridge (3) removably attachable to the housing. When the cartridge (3) is attached to the housing (9) the drive member (20) is operatively coupled to the pumping chamber membrane (47). The fluid delivery system may be applied to an infusion system for the infusion of a liquid therapeutic product, such as insulin.Type: GrantFiled: December 12, 2016Date of Patent: February 15, 2022Assignee: ViCentra B.V.Inventors: Tim Oakes, Joseph Cefai

Patent number: 11032714Abstract: The present invention proposes assigning a common system identification code to each of a control unit and a plurality of controllable slave units, storing that system identification code in a user-inaccessible memory of those units, and allowing pairing between the control unit and each of the slave units only if the system identification code of the control unit matches that of the respective slave unit. Thus a slave unit can only act upon a control signal if the control signal comes from the control master unit which shares the system identification code, i.e. is verifiably from the same family. This ensures that a slave unit only acts on instructions which come from a specified control unit, so providing security to the user. It is therefore impossible for a slave unit to act on instructions from any device other than the control master unit with which it shares a system identification code, which may be alternatively referred to as a family identification code or family ID.Type: GrantFiled: April 20, 2017Date of Patent: June 8, 2021Assignee: ViCentra B.V.Inventors: Tim Oakes, Joseph Cefai

Patent number: 10894123Abstract: The invention generally provides a fluid delivery system comprising: a reservoir (7); a pumping chamber (8) having a volume, an inlet valve (48), an outlet valve (49) and a membrane (47); an actuator (20); and a drive member (21). The inlet valve and the outlet valve each comprise a passive normally closed one-way check valve. The inlet valve provides selective fluid communication between the pumping chamber volume and the reservoir. Fluid in the reservoir is at substantially ambient pressure. The drive member is operatively coupled to the pumping chamber membrane. Energising the actuator moves the drive member in reciprocating motion and thereby displaces the membrane to change the pumping chamber volume between a minimum volume and a maximum volume. The pumping chamber volume is held at a pressure above the ambient pressure in the reservoir when the actuator is at rest.Type: GrantFiled: December 12, 2016Date of Patent: January 19, 2021Assignee: VICENTRA B.V.Inventors: Timothy William Oakes, Joseph Cefai

Patent number: 10854325Abstract: A system and method for processing instructions sent wirelessly between a control master unit and a slave device comprising a slave device memory is disclosed. The control master unit transmits an instruction to the slave device. The slave device writes the received instruction to the slave device memory; reads a stored instruction, corresponding to the instruction written to the memory, from the memory; and transmits the stored instruction to the control master unit. The control master unit compares the stored instruction to the instruction and, if the stored instruction is the same as the instruction, enables a process instruction to be sent to the slave device. In response to receiving the process instruction, the slave device processes the stored instruction.Type: GrantFiled: April 20, 2017Date of Patent: December 1, 2020Assignee: Vicentra B.V.Inventor: Joseph Cefai

Publication number: 20200101218Abstract: A therapeutic product delivery device is described which comprises a device body and a cartridge for holding a therapeutic product. An engagement structure is provided for releasably engaging the cartridge with the device body. A fault detector is provided for detecting a fault in the delivery of the therapeutic product from the cartridge. A release trigger is responsive to the detection of a fault to cause the engagement structure to release the cartridge from the device body. In this way, a fault causes the cartridge to be released from the device body, which will prevent any further delivery of the therapeutic product to the patient. This solution is strongly preferable to a solution in which a product delivery mechanism (e.g. a pump) is merely paused or stopped, since when the cartridge separates then no further delivery is possible at all, until the cartridge is reattached (or more probably replaced with a new cartridge in case the fault is with the cartridge).Type: ApplicationFiled: October 10, 2019Publication date: April 2, 2020Inventors: Julian Shapley, Matthew Powell, Ceri Clatworthy, Joseph Cefai
