  • Patent number: 8216178
    Abstract: A breast pump set for expressing human breastmilk comprises a breastshield (1) to be placed on the female breast with a coupling part (12) for connection to a milk collection container (2), and an electrically driven suction pump (4, 4?). The breastshield (1) is provided with an actuator (5) for actuating the suction pump. The inventive breast pump seat allows easy handling of the suction pump and eliminates the need for the mother to have a hand free for handling.

  • Patent number: 8105335
    Abstract: A manually manipulatable tool for removing a fecal impaction, the tool is adapted for insertion into a patient's rectum to engage and penetrate the impaction. The tool is fitted with flexible, arcuately configured elements collapsible at least partially during insertion into the rectum and penetration of the fecal impaction, withdrawal of the tool deploying the elements to exert traction on the impaction thus facilitating withdrawal of at least portions of the impaction. A body member of the tool is preferably elongated and can optionally be provided with a longitudinally extending lumen for introduction of an enema solution concurrently with or independently of impaction removal.

  • Patent number: 8083712
    Abstract: A flat-hose assembly has a proximal end and a distal end adapted for use with a negative pressure wound drainage system. The flat-hose assembly comprises a top layer, a bottom layer, and a filter layer. The bottom layer forms an opening at the distal end of the flat-hose assembly to allow exudates of a wound to flow into the flat-hose assembly. The filter layer is disposed between the top layer and the bottom layer. The top and bottom layer form a seal area along a periphery of the top layer and the bottom layer to seal the filter layer therebetween.

  • Patent number: 8075516
    Abstract: A portable breast pump has a suction unit and a collecting unit which is connected to this suction unit via a flexible suction line. The collecting unit comprises a breast shield, a milk-receiving container and a coupling element which connects the breast shield to the milk-receiving container. The suction unit has a housing with an operating means for operating the pump and a fastening means for fastening the housing on a carrying means, which can be fastened on the mother's body. This breast pump is easy to operate, allows the milk to be expressed even in confined areas with no set-down surfaces and, in addition, does not hinder the mother's mobility.

  • Publication number: 20110301569
    Abstract: The present invention provides an indirect method and accompanying apparatus for supplying a high concentration of medicaments, particularly antibiotics, to the nasal sinuses by first loading the medicament into the cerebrospinal venous system (CVCS) via a Valsalva manuever. Because the CVCS is a valveless, three-dimensional closed system, traditional physiological dogma such as veins always draining tissues does not always apply. Instead, because in its closed-system blood can flow in any direction, the blood of the CVCS and any medicaments that it contains will be drawn to any portion of it where there is increased outflow, such as the copious venous-derived sinus fluid drainage present during nasal allergy or nasal infection. Thus, the very nasal congestion that impedes the effectiveness of direct medicament application, such as seen with nasal inhalers or systemic antibiotics, aids in applying the medicament indirectly to the nasal sinuses via the CVCS.

  • Patent number: 8070716
    Abstract: A breastpump, manual or motorized, that includes a mechanism to regulate pressure change, e.g., vacuum, within a breastshield chamber, including in some cases to a maintained minimum pressure that is less than ambient (atmosphere). The pressure regulator provides control for varying negative pressure between a minimum value and a maximum value (and values in between), or to achieve a specific actually measured negative pressure value within a breastshield.

  • Patent number: 8048023
    Abstract: Systems and methods for nasal irrigation are provided in which a nasal irrigation device includes a source of saline solution, an effluent receptacle, a nasal interface, a vacuum source, a fluid passageway to communicate the source of saline solution with the effluent receptacle through the nasal interface and a nasal cavity of the user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline solution through the fluid passageway. The saline solution source is disposed relative to the device to provide gravitational inducement of saline solution to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and the relative vacuum from the effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of a user. The entire device is assembled as a hand-held device for convenient lifting and disposal against the user's nostrils.
