| titleOfInvention | Needle unit with biostatic chamber |
| abstract | The invention provides a needle unit (10, 310, 410, 510) having a proximal space (13, 513) adapted to accommodate a portion of a variable volume reservoir, the needle unit (10, 310, 410, 510) comprising: a needle holder (15, 315, 415, 515); a needle cannula (21, 121, 221, 321, 421, 521) fixed to the needle holder (15, 315, 415, 515) and comprising a distal needle end (23, 123, 223, 323, 423, 523) for providing fluid communication with an injection site; a needle shield (50, 350, 450, 550) carrying a sealed chamber (38, 138, 238, 338, 438, 538) for receiving a distal portion of the needle cannula (21, 121, 221, 321, 421, 521), the sealed chamber (38, 138, 238, 338, 438, 538) being distally sealed by a penetrable self-sealing septum (39, 139, 239, 339, 439, 539); and a flow channel (24, 124, 224, 324, 424, 524) for establishing fluid communication between the sealed chamber (38, 138, 238, 338, 438, 538) and the proximal space (13, 513), wherein the needle shield (50, 350, 450, 550) and the needle holder (15, 315, 415, 515) are relatively movable between a first relative position in which the sealed chamber (38, 138, 238, 338, 438, 538) houses the distal needle end (23, 123, 223, 323, 423, 523) and a second relative position in which the distal needle end (23, 123, 223, 323, 423, 523) protrudes from the sealed chamber (38, 138, 238, 338, 239, 339, 439, 539) through the penetrable self-sealing septum (39, 139, 239, 339, 439, 539); and wherein the needle cannula (21, 121, 221, 321, 421, 521) further comprises a side aperture (25, 125, 225, 325, 425, 525), the side aperture (25, 125, 225, 325, 425, 525) being in fluid communication with the flow channel (24, 124, 224, 324, 424, 524) and positioned within the sealing chamber (38, 138, 238, 338, 438, 538) when the needle shield (50, 350, 450, 550) and the needle holder (15, 315, 415, 515) are in the second relative position. |
