Abstract
A device for removing fluid from a body, the device comprising an array of microneedles and a housing; the array of microneedles being disposed within the housing and the housing defining a chamber. The microneedles are moveable between a disengaged position and an engaged position where, in use in the engaged position, the microneedles penetrate the surface of a body. The chamber is adapted to surround the surface of the body through which the microneedles penetrate when in the engaged position. The chamber is configured for connection to a vacuum device such that negative pressure can be applied to the chamber.
Claims19
A device for removing fluid from a body, the device comprising:
- i) an array of microneedles;
- ii) a housing, the array of microneedles being disposed within the housing, and the housing defining a chamber;
- and
- iii) an applicator for applying the array of microneedles to a surface, wherein the applicator includes a pressure element to contact a contact element associated with the array of microneedles, the contact element being the housing, and a hammer configured to be driven from a primed position to an impact position to deliver an impulse to the pressure element,
- wherein the pressure element is operably connected to the hammer whereby exertion of a force on the pressure element allows the hammer to be driven from the primed position to the impact position.
An applicator for applying a microneedle array to a surface, the applicator comprising:
- a pressure element to contact a contact element associated with a microneedle array to be applied to a surface;
- and
- a hammer configured to be driven from a primed position to an impact position to deliver an impulse to the pressure element,
- wherein the pressure element is operably connected to the hammer whereby exertion of a force on the pressure element allows the hammer to be driven from the primed position to the impact position.
