  • Patent number: 10537683
    Abstract: A finger grip for receiving and retaining a syringe body of an injection syringe. The finger grip is easily pressed directly onto the syringe and employs a centering feature and a pair of one way, flexible latches that allow easy attachment to a syringe body yet ensures retention during normal and abnormal use. If a high horizontal component force is applied during normal or abnormal use, the finger grip will not become disconnected in an uncontrolled fashion from the syringe body, which might cause injury and/or damage to a patient being injected. The flexible latches may prevent detachment of the finger grip from the syringe below separation force of about 25 lbs.

  • Publication number: 20160106466
    Abstract: Method and device for distending a gynecological cavity. According to one embodiment, a mechanical, non-fluid device is used to distend the gynecological cavity. Such devices include, for example, self-expanding members, such as resilient baskets, coils, whisks, prongs, and loops, or mechanically expanded members, such as inflatable balloons, mechanically-expanded cages and loops, and scissor jacks. The device may serve a purpose in addition to distension, such as illumination, imaging, irrigation, drug delivery, resection and cauterization.

  • Patent number: 9271619
    Abstract: A floor care appliance is provided for cleaning bare surfaces such as tile, marble, linoleum and wood. The floor care appliance is comprised of a base portion having a suction nozzle and a brush block having a plurality of vertical axis rotary agitators for cleaning bare floors. The rotary agitators are driven by an independent motor for agitating the floor surface. With the addition of an accessory hose and tools, the cleaning utility can be expanded to areas wherein the suction nozzle cannot normally reach such as behind the toilet, shower walls, and the grout between tile. While used in the capacity for cleaning bare floors, the floor care appliance can be moved between three modes by a rotating a member located on the upper housing. The first mode is dry mode, the second mode is wet scrub mode and the third mode is wet pickup mode. The accessory tools are stored in an accessory caddy that is placed freestanding over the suction nozzle and in front of the housing.

  • Publication number: 20160037951
    Abstract: Systems, devices and methods for holding a cut live tree in an upright position. A Christmas tree stand comprises a supporting base and non-penetrative one-way-pushable screws. Threads in the nuts through which the screws are disposed are pushed out of the way (disengaged from the threads on the screws) when the screws are pushed towards a tree placed in the base, but not when the screws are pulled away from the tree. This makes the screws much easier to push towards the tree than to pull them away, making secure fastening of the tree quick and easy. Screws can also be tightened to provide finer screw adjustment. Non-penetrative screws allow the cut tree to remain fresh longer.

  • Patent number: 7367082
    Abstract: A floor care appliance is provided for cleaning bare surfaces such as tile, marble, linoleum and wood. The floor care appliance includes a port for the connection of an accessory hose and wand for off the floor cleaning. A variety of cleaning implements can be attached to the wand for cleaning hard to reach bare surfaces such as tile and grout. The port includes a suction inlet, cleaning solution outlet, and an air turbine inlet for an air turbine pump which pressurizes the cleaning solution. A pivoting door seals the suction inlet, cleaning solution outlet, and air turbine inlet when the accessory hose and wand are not in use.

  • Patent number: 7152757
    Abstract: A coupling for connection of a tube comprises a coupling housing which includes a first end into which the tube is inserted, a clamping ring which is positioned in the coupling housing against a first conical surface, a sealing ring which is positioned in the coupling housing, and a return ring which is positioned in the coupling housing between the clamping ring and a second end of the housing adjacent a second conical surface that is tapered opposite to the first conical surface. The return ring is expandable and comprises a central aperture which is smaller than the external diameter of the tube. Accordingly, when the tube is pushed into the coupling housing and forced through the return ring, the return ring will expand and move along the second conical surface.
