Abstract: A medical device and method configured to disinfect a skin surface, the device comprising a power source that provides electric power, a light emitting source that uses electric power received from the power source to disinfect the skin surface, and a switch that is configured to be operated by user action, wherein upon activation of the switch, the electric power from the power source is received by the light emitting source to emit visible light and disinfect the skin surface.

Abstract: An accessory (60) configured to be attached to a medical device (10) to disinfect a skin surface or a portable medical device surface (54). The accessory (60) comprising a plurality of disinfecting materials (68), and a mounting mechanism (62) that is configured to attach and detach the accessory (60) to the medical device (10).

Abstract: A needle hub assembly for a pen needle includes a needle hub, a cannula or needle coupled to the needle hub, a retractable and compressible sleeve covering at least one end of the cannula, and an outer cover. The outer cover encloses the needle hub and the retractable sleeve. The retractable sleeve is coupled to the hub to cover the end of the cannula where the sleeve can pass through or can be pierced by the cannula and the sleeve retracts axially on the cannula. The sleeve is resilient and returns to an original configuration when an insertion force is released. The needle hub can have a first sleeve to cover a patient end of the cannula, and second sleeve to cover a non-patient end of the cannula where the sleeves retract onto the cannula or hub and expand to the original configuration to cover the ends of the cannula.

Abstract: A universal add-on for an injection pen is provided. A static portion (110) has opposing gripping members to grip a body (112) of the injection pen. A moving portion (106) has opposing gripping members to grip an actuator (114) of the injection pen. Displacement measurement devices (102) measure relative linear and rotational movement of the actuator relative to the injection pen body (112). Doses are determined and recorded based on relative movement of the static portion (110) and moving portion (106), and the dose data is transmitted wirelessly to a mobile device. The device is easily installed on injection pens by pressing opposing buttons to relieve gripping pressure imparted by the gripping members.

Abstract: A two-part cap (100) for an injection pen (106) is provided. The cap includes a static portion (102) that remains on the pen injector (106), and a removable portion (104). The static portion (102) includes a dose sensor (126) for sensing movement of a plunger (118) within a reservoir (114) of the pen injector (106). A delivered dose is calculated based on the detected plunger movement.
