A joining element has an anchoring portion for in-depth anchoring in the object and a head portion arranged proximally of the anchoring portion with respect to an insertion axis. The head portion has a lateral outer surface that has a structure that is well-defined, especially within tight tolerances. The joining element is positioned relative to an object of a non-liquefiable material such that the anchoring portion reaches into an opening of the object or is placed adjacent a mouth thereof. Then, the joining element is pressed towards a distal direction, to press the anchoring portion into the opening, while mechanical vibration energy is coupled into the joining element by a tool, in an amount and for a time sufficient for liquefaction of a portion of the thermoplastic material to cause interpenetration of the thermoplastic material into structures of the object.

A cover plate, a method of manufacturing the cover plate, and an electronic device having the cover plate are provided. The cover plate includes a substrate, at least one slot defined in the substrate and penetrating through the substrate, and a filling layer received in the slot including an insulating layer and a gel layer located on the insulating layer.

A first object is anchored in a second object. The first object has a material with thermoplastic properties, and the second material has a material that is solid and is penetrable by the first material when in a liquefied state. The second object has an insertion face with an opening having a mouth in the insertion face, and the first object has an insert portion that for anchoring is placed in the opening or about the mouth thereof. For anchoring, energy suitable for liquefaction of the first material impinges in an amount and for a time sufficient for at least partial liquefaction of the first material and interpenetration of the first and second materials. The second object, around the opening, has an anisotropic strength with respect to forces perpendicular to the opening axis.

In more particular embodiments, the polymer coating may be silicone or polyethylene, for example. The dressing may additionally include a drape disposed over the tissue interface and a port fluidly coupled to the tissue interface through the drape. The tissue interface may be applied over a tissue site, and therapeutic levels of negative pressure may be applied to the tissue site through the tissue interface.

A resin panel according to an embodiment includes a core material, a reinforcing material, a skin material covering the core material and the reinforcing material, and a fastened member. A reinforcing material has a first plate provided on a front surface of the core material, a second plate provided on a back surface of the core material, and a connecting plate connecting the first plate and the second plate. The fastened member is attached to the skin material by a fastening member penetrating the skin material and the first plate or the second plate of the reinforcing material.

A method for manufacturing a valve unit includes fixing a first flow channel member and a flexible member to one another, the first flow channel member including a first surface, a second surface and a through-hole passing through the first surface and the second surface, in a manner in which the flexible member is supported by a fixing member and the through-hole is covered at the first surface side thereof by the flexible member; and fixing the first flow channel member and a second flow channel member, the second flow channel member including a hole through which a valve body passes, in a manner in which the through-hole is in communication with the hole at the second surface side of the through-hole, the valve body configured to open and close a flow channel in communication with the through-hole according to displacement of the flexible member.

Dressings for tissue treatment with negative pressure and methods of assembling the dressings for tissue treatment with negative pressure are disclosed. A method of assembling a dressing, which may comprise at least three layers assembled in a stacked relationship, may comprise providing an assembly station having at least one retaining pin, placing a first layer on the assembly station, placing a second layer on the assembly station, and bonding the second layer to the first layer. The first layer may comprise a plurality of apertures, at least some of which may be engaged by the retaining pins, and the second layer may comprise fluid restrictions and alignment areas for engaging with the retaining pins so that the fluid restrictions may be aligned with the apertures of the third layer.

A dressing for treating a tissue site with negative pressure may comprise a cover having an adhesive, a manifold, a perforated polymer film, and a perforated silicone gel having a treatment aperture. The cover, the manifold, the perforated polymer film, and the perforated silicone gel may be assembled in a stacked relationship with the cover and the perforated silicone gel enclosing the manifold. The perforated polymer film may be at least partially exposed through the treatment aperture, and at least some of the adhesive may be exposed through the perforated silicone around the treatment aperture.

Systems and methods for controlling and/or calibrating a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes calculating an amplitude and an offset for a drive signal based at least in part on previously calculated parameters and a negative pressure setting, generating the drive signal, and applying the drive signal to a pump system. The pump system can be fludicially connected to a wound dressing positioned over a wound.

Apparatuses for use in negative pressure wound therapy are described herein. In some embodiments, the apparatus includes a pump assembly having a pump housing, a magnet, an electrically conductive coil, and a diaphragm, wherein the electrically conductive coil is configured to move a portion of the diaphragm to pump a fluid through the pump apparatus, and a dampener positioned within the pump assembly configured to reduce sound generated by the pump assembly during operation of the pump assembly. In some embodiments, the apparatus includes a housing having a first section and a second section, and an illumination source disposed within the housing adjacent the first section, wherein the illumination source is configured to illuminate the first section, wherein the first section is one of transparent and translucent, and wherein the first section is thinner than the second section as measured perpendicularly from inside to outside the housing. In some embodiments, the pump apparatus includes components configured to be laser welded together.
