  • Patent number: 9616164
    Abstract: A device and method for detecting recirculation for an extracorporeal blood treatment apparatus and an apparatus with a device for detecting recirculation are based on targeted haemodilution by administration of a substituate bolus, causing a pressure change in venous and arterial branches of the extracorporeal circuit due to a viscosity change of flowing fluid. Recirculation is detected based on detection of the pressure change. The device includes a control unit cooperating with a device for conveying blood and a device for supplying substituate. The control unit provides an operating mode for detecting recirculation, in which blood flow rate is reduced during administration of a substituate bolus. With simultaneous substituate bolus administration and reduction of blood flow rate, the composition of fluid flow is optimized for detection of recirculation, so that fairly large pressure changes result in venous and arterial branches, thereby improving sensitivity and reliability of the measurement method.

  • Patent number: 9616168
    Abstract: The invention relates to a medical device and a method for delivering at least one fluid from a medical device. More particularly, the present patent application relates to medical devices for delivering at least one, in particular two drug agents from separate reservoirs. The technical problem of preventing after-dripping and at the same time improving the safety and the dose accuracy of a medical device is solved by a method for delivering at least one fluid from a medical device, wherein the fluid is ejected from a reservoir by an advancing movement of a bung, wherein an electromechanical device is instructed to move the bung via a piston over a predetermined distance and wherein, after a dwell time following the advancing movement of the piston, the piston is retracted by the electromechanical device.

  • Patent number: 9616173
    Abstract: An auto-injector for injecting a fluid medicament into a patient from a pre-filled syringe requires a disposable cassette that is selectively engageable with the reusable injector. The syringe is latched onto the cassette, and the cassette is then engaged with the injector. Activation of the injector causes a first motor to move the syringe so its needle is extended from a concealed position inside the cassette for injection of the medicament. A second motor on the injector is then activated to expel fluid medicament from the syringe. Then, the first motor is again activated to withdraw the syringe into the cassette for disposal of the cassette/syringe after an injection.

  • Patent number: 9616202
    Abstract: A treatment device includes: a balloon; a biologically active agent part applied on an outer surface of the balloon; a protective sleeve encircling the balloon and being displaceable proximally; and an interposed member having a self-expanding function arranged between the balloon and the protective sleeve. When the protective sleeve is moved proximally in order for the balloon to be exposed to the inside of a blood vessel, the presence of the interposed member prevents the biologically active agent part from being scraped and peeled off by the inner surface of the protective sleeve.

  • Patent number: 9616203
    Abstract: A method and device are provided for simultaneously or near-simultaneously diagnosing and treating tension pneumothorax and/or hemothoraxA Veress-type needle portion includes a hollow needle for puncturing the chest wall over a blunt hollow probe biased by one or more springs to extend distally into the pleural cavity. Openings in the blunt hollow probe connect via a pathway to an automatic check valve, which permits the flow of air and/or fluid only in a proximal direction. Pressure from within the pleural cavity is transmitted to the interior surface of a pressure documenter. If pressure greater than atmospheric pressure is present in the pleural cavity, the pressure documenter will be automatically urged proximally to simultaneously allow air and/or fluid to escape from the pleural space through the device, thus treating the tension pneumothorax and/or hemothorax, as well as providing a stable indicator to positively document the diagnosis of increased pressure.

  • Patent number: 9616206
    Abstract: The invention relates to an electronic pill (102) for delivery of a medication (104) inside a mammal. The electronic pill (102) comprises a reservoir (106) for releasing the medication (104) in response to a predefined level of pressure. Furthermore a primary elastic element (108) is comprised for applying said predefined level of pressure to the reservoir (106) via a piston (110) upon release from the piston (110) of its constrained position. The piston (110) in its turn, when in constrained position, induces a predefined level of stress in the primary elastic element (108) by accordingly deforming it. The electronic pill (102) comprises a mechanism (114) for changing, upon actuation, from a constraining configuration in which the piston (110) is maintained at its constrained position to a releasing configuration in which the piston (110) is released.

  • Patent number: 9616208
    Abstract: An apparatus for cleansing and promoting tissue growth in wounds, in which irrigant fluid optionally containing cell nutrients and/or other physiologically active material from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing, a biodegradable scaffold in contact with the wound bed and a means for fluid cleansing and back to the dressing. The apparatus has means for supplying thermal energy to the fluid in the wound. The cleansing means (which may be a single-phase, e.g. micro-filtration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.

  • Patent number: 9616209
    Abstract: A single-piece, injection molded, hand-held liquid dispensing applicator. The single-piece applicator comprising a source of fluid and a frangible applicator tip attached to the fluid source. When the frangible applicator tip is broken, the fluid flows from the source to an absorbent member attached to the applicator tip to spread the liquid on a surface. The frangible tip may comprise a support element permanently connected to the fluid source, a relatively rigid tongue element, and a frangible region therebetween. The tongue element may comprise ribs for reinforcement. The frangible tip may comprise a semi-permeable or non-permeable cover to control the speed and direction of the dispersion of the fluid. The dispensing applicator may be used in various medical applications.
