Patent number: 8308726Abstract: A system to minimize fluid turbulence inside a tissue cavity during endoscopic procedures. A body tissue cavity of a subject is distended by continuous flow irrigation using a solenoid operated pump on the inflow side and a positive displacement pump, such as a peristaltic pump, on the outflow side, such that the amplitude of the pressure pulsations created by the outflow positive displacement pump inside the said tissue cavity is substantially dampened to almost negligible levels. The present invention also provides a method for accurately determining the rate of fluid loss into the subject's body system during any endoscopic procedure without utilizing any deficit weight or fluid volume calculation, the same being accomplished by using two fluid flow rate sensors. The present invention also provides a system of creating and maintaining any desired pressure in a body tissue cavity for any desired cavity outflow rate.Type: GrantFiled: September 1, 2005Date of Patent: November 13, 2012Inventors: Atul Kumar, Alka Kumar

Publication number: 20110295205Abstract: According to one embodiment, a cannula assembly may include a cannula module and an inserter module. In the pre-operational state the cannula is retracted with respect to the skin-contacting surface. In operational state the cannula projects beyond the skin-contacting surface. The inserter module may include an energy store and an activation mechanism. When the energy store is at least partially discharged, the stored potential energy is transformed to kinetic energy that moves the cannula from the pre-operational state to the operational state. The activation mechanism is triggerable from outside the cannula assembly with a trigger device. The activation mechanism prevents the energy store from being discharged before it is triggered by the trigger device, and enables the energy store to be discharge after it is triggered by the trigger device to force the cannula from the pre-operational state into the operational state.Type: ApplicationFiled: November 22, 2010Publication date: December 1, 2011Applicant: Roche Diagnostics International Ltd.Inventors: Heiner Kaufmann, Simon Scheurer, David Teutsch

Patent number: 7806866Abstract: A device for automatically injecting an active agent, the device involving a syringe filled with an active agent and carrying an injection needle, the syringe displaceable in a receiver by the tension of a spring. A transmission displaceable by at least one spring traverses a first partial path for sticking the injection needle and a second partial path for emptying the active agent from the syringe. The at least one spring acts between the transmission and an intermediate part, and another spring acts between the intermediate part and a support fixedly connected to the receiver. An indicator visible from the outside is connected to the intermediate part, moves only during the second partial path, and traverses a path length that is substantially smaller that the sum of both partial paths.Type: GrantFiled: May 20, 2005Date of Patent: October 5, 2010Assignee: TecPharma Licensing AGInventors: Edgar Hommann, Benjamin Scherer, Lorenz Broennimann

Publication number: 20100228193Abstract: Medicine injection apparatuses having multiple chambers. The chambers may be in lateral relationship. A torsional part is adapted to turn and be repositioned angularly relative to a main body to allow different chambers to be used to receive an injection assembly. The medicine injector can be constructed to administer multiple doses. The apparatuses may also have a storage chamber for storing the injection assembly after use. Plural drivers may be used to administer multiple doses, such as at the different angular positions of the torsional part. The apparatuses may allow multiple automatic injections from different angular positions and storage of an injector after use. Needle fright is reduced by minimizing exposure of an injection needle prior to injection.Type: ApplicationFiled: March 4, 2009Publication date: September 9, 2010Inventor: Ronald E. Wyrick

Publication number: 20100228226Abstract: The invention relates to an inserter for a medical device e.g. an infusion set or the like for intermittent or continuous administration of a therapeutical substance, such as e.g. insulin. The inserter comprises a needle hub comprising an insertion needle and two elastic elements assuring automatic insertion and automatic retraction of the insertion needle. Activation of the first elastic element (11) cause a penetrating member (6A) to be inserted sub-or transcutaneously into the skin of a patient, and the second elastic element (12) cause the penetrating member (6A) to be retracted from the skin of the patient. The first elastic element (11) is in an unloaded state before activation and upon activation the first elastic element (11) energizes the second elastic element (12).Type: ApplicationFiled: July 2, 2008Publication date: September 9, 2010Inventor: Jens Egebjerg Nielsen

Publication number: 20100100040Abstract: A disposable injector with a housing (10) in which are arranged at least one mechanical spring energy reservoir (50), at least one cylinder/piston unit (100), at least one piston-actuating ram, and at least one trigger unit. For this purpose, the housing has at least one inverted draw hook, which has at least one support surface respectively in the region of its free end. The spring-loaded piston-actuating plunger rests on the support surface, whereby the contact zone placed between the draw hook and the piston-actuating plunger represents a variable-speed gear pair thrusting the draw hook radially outwards. The locking position of the draw hook is secured by an actuating element positioned in a locked position. The actuating element has a triggering position which effects radially outwards aligned retreat of the draw hook when the piston-actuating plunger is released.Type: ApplicationFiled: December 14, 2009Publication date: April 22, 2010Inventor: Rudolf Matusch
