Abstract: A system and method for a patch-like, self-contained substance infusion device which can be attached to a skin surface via an adhesive contact surface. A push button activation assembly can then be used to remove an interlock, allowing a disk or Belleville spring assembly to apply an essentially even and constant pressure to the contents of a fluid reservoir assembly. This allows the release of one or more spring-loaded patient needles into the skin surface, and establishes a fluid communication path between the patient needles and the pressurized fluid reservoir contents thereby delivering an infusion into the skin. The push button activation assembly further allows the release of one or more improved safety mechanisms after use.

Abstract: A system and method for a patch-like, self-contained substance infusion device (700) which can be attached to a skin surface via an adhesive contact surface. A push button (780) activation assembly can then be used to remove an interlock (730), allowing a disk or Belleville spring (735) assembly to apply an essentially even and constant pressure to the contents of a fluid reservoir assembly (710). This allows the release of one or more spring-loaded patient needles (760) into the skin surface, and establishes a fluid communication path between the patient needles (760) and the pressurized fluid reservoir contents thereby delivering an infusion into the skin. The push button (780) activation assembly further allows the release of one or more improved safety mechanisms (794) after use.

Abstract: An apparatus includes and ampoule and a protective sleeve. The ampoule includes a body portion and an openable end portion. The body portion defines an internal cavity for containment of a substance. The openable end portion is configured to be opened by removal of a distal section, which upon removal creates an opening into the internal cavity of the body portion for liberation of the substance from the internal cavity. The protective sleeve is disposed over at least a portion of the openable end portion. The protective sleeve provides a contamination barrier to prevent contamination of an outer surface of the openable end portion covered by the protective sleeve.

Abstract: A one-piece low drag septum is provided for preventing escape of fluid from an introducer needle during removal of such a needle from a catheter and introducer needle assembly. The septum generally includes a distal portion, a proximal portion, a cavity portion, and a longitudinal axis. The distal portion acts as a primary seal to prevent escape of blood from the catheter into the assembly and is generally positioned furthest away from the user of the apparatus and nearest the patient. The cavity portion reduces friction placed on the introducer needle. The proximal portion of the septum acts as a secondary seal to prevent escape of material from the cavity, seals the cavity, and wipes the needle as it is being withdrawn from the catheter assembly.

Abstract: An oral cleaning device is described. The oral cleaning device includes a brush head, a stem, a suction adapter, and a supply reservoir. The brush head includes a cleaning surface and defines an internal cavity. The stem is coupled to the brush head. The stem includes a fluid channel for bi-directional fluid flow to dispense fluid out of the brush head and to suction fluid into the brush head. The suction adapter is to the stem. The suction adapter couples a suction device to the stem for providing a suction flow within the stem in response to control by a user. The supply reservoir includes an integrated supply adapter to couple the supply reservoir to the suction adapter. The supply reservoir contains a water-based cleaning solution with less than a prescription amount of a cleaning agent.

Abstract: A system and method for a patch-like, self-contained substance infusion device (700) which provides one or more substantially hidden patient needles (760) which can be placed in fluid communication with a fluid reservoir assembly (710) that includes a rigid bladder portion (712) used in conjunction with a non-distensible bladder film (740), such as a metallized film. The device (700) can be attached to a skin surface via an adhesive contact surface and a push button (780) activation assembly can then be used to remove an interlock (730), allowing a disk, or Belleville spring (735) assembly to apply an essentially even and constant pressure to the contents of a fluid reservoir assembly (710).

Abstract: A needle assembly with needle shield that is connected to the needle hub by a tether. The tether prevents unwanted proximal movement of the needle with respect to the needle shield once the needle has been withdrawn into the needle shield. The tether is maintained in its compressed state by use of the invention for ease of assembly.
