  • Patent number: 9844456
    Abstract: Methods are disclosed for converting on a mass scale elongated material webs into finished parts or devices. Slits form strands in a web, the strands comprising interconnected objects which correspond to parts of finished devices. Strands are combined with additional webs to form a material laminate from which finished devices are die cut. The methods are suitable for a range of converting applications including medical devices, particularly the external nasal dilator. Complex dilator devices produced from the methods are formed as a single body truss having horizontal regions adapted to engage outer wall tissues of first and second nasal passages of a nose. When in use the dilator stabilizes or expands nasal outer wall tissues and prevents the outer wall tissues from drawing inward during breathing. Methods of manufacture comprise separate steps for fabricating and assembling the elements and layers of finished dilator devices and for packaging finished devices individually or in groups.

  • Publication number: 20150051566
    Abstract: The purpose of the present disclosure is to provide an absorbent article that can be made smaller because the crown section continues to fit the wearer's excretory opening, which has a complex shape, both when dry before absorbing menstrual blood and when wet after absorbing menstrual blood, and with which leakage does not occur easily. This absorbent article is as follows: The absorbent article (1), which comprises a liquid-permeable top sheet (4), a liquid-impermeable back sheet, and a specified absorbent (7) between the liquid permeable top sheet (4) and the liquid-impermeable back sheet, is characterized in that: the absorbent article (1) has a crown section (2), which protrudes in the thickness direction of the absorbent article (1) in the region that is in contact with the excretory opening and comprises a specified cushion section; and in the central section, the crown section (2) has a compression workload (WC) of 10-50 (N·m/m2) and a compression resilience (RC) of 35-100%.

  • Publication number: 20150045756
    Abstract: An absorbent core composite is disclosed for incorporation into a disposable absorbent article. The composite includes a first material layer and a second material layer (preferably nonwoven) partially secured to the first material layer to define at least one pocket therebetween. Preferably, multiple pockets are defined, except in the case of where a generally uniform layer or bed of absorbent is preferred or better suited fro the application. The pocket is said have a fixed initial volume. Further, an aggregate of absorbent particles is provided in the pocket(s) to occupy a portion of the fixed initial volume. The absorbent particles are preferably SAP particles and is characterized by a dry volume associated with a dry state and a swell volume associated with a liquid saturation state. In respect to or for the pocket, the aggregate is characterized by a collective dry volume and a collective swell volume, wherein the pocket has an initial configuration that retains the aggregate therein.

  • Patent number: 8876780
    Abstract: An attachable needle storage device is provided with a main body and a rotatable sleeve and a plurality of new needles stored within the sleeve, a leaf spring to direct each needle into a circumferential position of the pen body when rotated, and a ramp to move the needle into an axial position of the pen body when retracted or pulled rearward by the user. The attachable needle storage device is configured to attach to a pen device in a manner substantially the same as a conventional needle hub. In doing so, the rotation of the sleeve can be used to rotate a new needle onto a shuttle, and the retraction of the device can be used to cause a ramp to engage the needle and needle hub, moving the needle toward the axial position of the pen body and the septum. Once under the septum, the user continues pulling the device rearward, such that the needle is then moved rearward, pierces the septum of the medicament cartridge and exposes the distal end of the needle for injection.
