Patent number: 11344701Abstract: A urinary catheter assembly comprises: a urinary catheter, a tubular case and a sleeve fixedly arranged over at least a part of a non-insertable section of the urinary catheter. The sleeve includes two oppositely arranged openings and a body extending between the opening. In a first position, a storage position, the tubular case is arranged to enclose the insertable section of the urinary catheter and is removably connected to the sleeve and/or to the non-insertable section of the urinary catheter. The body portion of the sleeve is provided with a first engagement member, and the tubular case is provided with a second engagement member, thereby enabling the tubular case, when removed from the non-insertable part of the urinary catheter, to be releasably connected to the sleeve in a second disposition, the second disposition being different from the first disposition. A method for producing a urinary catheter assembly is also disclosed.Type: GrantFiled: May 23, 2019Date of Patent: May 31, 2022Assignee: DENTSPLY IH ABInventors: Per Andersin, Karsten Eriksson, Isak Folenius, Michael Sandberg

Patent number: 11123477Abstract: Disclosed are irrigation systems and methods, which can be used for rectal/anal irrigation. One example system includes a reservoir for an irrigating liquid, a probe for arrangement in a user, tubing providing fluid communication between the reservoir and probe, and an electrical pump for indirectly pumping irrigation liquid from the reservoir to the probe through said tubing. The electrical pump is controllable to assume a plurality of predetermined flow rates. The system includes an electrically operable valve to continuously control a degree of openness of the tubing, a flow sensor to measure an actual flow rate of the irrigation liquid in the probe, and a controller to obtain a desired flow rate, and control the flow rate of the electric pump to one of the plurality of flow rates exceeding the desired flow rate, and to continuously regulate the electrically operable valve based on the measured actual flow rate.Type: GrantFiled: September 15, 2017Date of Patent: September 21, 2021Assignee: DENTSPLY IH ABInventor: Göran Eliasson

Patent number: 11058847Abstract: A catheter assembly is disclosed, comprising a catheter, such as a urinary catheter, which at least a partly is provided with hydrophilic coating. The catheter assembly further comprises a wetting fluid. The receptacle is in direct contact with the hydrophilic coating of the catheter over the part of the catheter with the hydrophilic coating. This may, for example, be achieved by using a shrink wrap material. In order to accomplish adequate wetting, channels or the like may be provided on the inner surface of the receptacle or the outer surface of the catheter.Type: GrantFiled: March 14, 2019Date of Patent: July 13, 2021Assignee: DENTSPLY IH ABInventors: Evelina Gustavsson, Jan Utas

Patent number: 11027055Abstract: An irrigation system is disclosed that can be uses in, for example, rectal irrigation. The system comprises a reservoir for an irrigating liquid and a probe for arrangement in a user. The probe includes an inflatable balloon for fixing the catheter in a body cavity. A first pump is provided to pump irrigation liquid from the reservoir to the probe, and a second pump is provided to pump a fluid to the balloon for inflation. A control unit controls the transfer of the irrigation liquid and the fluid, and includes a valve for releasing fluid from the balloon for deflation. Tubing provides fluid communication between the reservoir, control unit and probe. The control unit and the first and second pumps are further arranged as an integrated unitary component, and the manually operable balloon control element is arranged in the vicinity of the second pump.Type: GrantFiled: January 30, 2019Date of Patent: June 8, 2021Assignee: DENTSPLY IH ABInventor: Erik Andréen

Patent number: 11020564Abstract: An insertion aid for catheter manipulation is disclosed. The insertion aid can be used for urinary catheters, such as hydrophilic urinary catheters for intermittent use. The insertion aid includes first and second plate-like arms arranged overlying each other and with a separation distance there between. The insertion aid also includes a resilient hinge connecting adjacent marginal edges of the plate-like arms together. At least one of the plate-like arms includes a groove on its clamping inner surface for holding a catheter shaft. The groove extends at least partly in the same direction as, and essentially parallel to, the resilient hinge, and is arranged at a distance both from the resilient hinge and from the marginal edge of the plate-like arm.
