摘要：
A safety needle device having a housing, a retractable sheath, and a needle cannula. The retractable sheath includes a tubular portion that is slideably mounted about a portion of the housing to completely or partially encase the length of the cannula. The retractable sheath includes a sheath bevel at the distal end having a blunted or angled tip. The angled tip being configured to suitable injection angles and may be fixed or rotatable. The sheath bevel may include a skin-engaging contact surface at the distal end. The needle may be connected to a needle hub at the proximal end of the housing and includes a needle bevel at the distal end. The sheath bevel and needle bevel may be offset from each other. A safety needle device having a retractable sheath having a graduated injection depth gauge to indicate needle penetration is also disclosed.
摘要（中）：
一种具有外壳，可伸缩护套和针套管的安全针装置。 可伸缩护套包括可绕壳体的一部分可滑动地安装的管状部分，以完全或部分地包围套管的长度。 可伸缩护套包括在远端具有钝角或倾斜尖端的护套斜面。 倾斜的尖端构造成适合的注射角度并且可以是固定的或可旋转的。 护套斜面可以包括在远端处的皮肤接合的接触表面。 针可以在壳体的近端处连接到针座，并且在远端处包括针斜面。 护套斜面和针斜面可能彼此偏移。 还公开了具有可伸缩护套的安全针装置，其具有用于指示穿刺的刻度注射深度计。
