摘要： An indwelling needle 1 is constituted by a body 3 having a closed end, a needle 4 with which a sharp edge 4a is formed at the tip, a tubular hub 5 retaining the proximal end of the needle 4 while sliding along the main body 3, a protective cover 6 sliding along the main body 3 while projecting from the main body 3 in a left direction of the drawings, and a spring 7 elastically fitted between the body and the protective cover.When a first projection 23b is lifted by operating an actuating lever 23 provided on the body to be retracted along with the protective cover relative to the body, the first projection 23b is housed in a through hole 14 and presses a second projection 31 of the protective cover engaged with a second engaging portion 13b toward the inner circumference, so that a use state of the protective cover and the body is released and the protective cover is projected from the body by elastic force of the spring.The total length of the indwelling needle 1 in the use state can be shortened, inhibiting damage to a blood vessel or the like.

摘要： Indwelling needle composed of a body having a closed end, a needle forming at the tip a sharp edge, a tubular hub retaining the proximal end of the needle and slidable along the main body, a protective cover slidable along the main body and projecting from the main body, and a spring elastically fitted between the body and the protective cover.When a first projection is lifted by actuating a lever provided on the body and retractable along with the protective cover relative to the body, the first projection is housed in a through hole and presses a second projection of the protective cover engaged with a second engaging portion toward the inner circumference, rendering an operative state.The resultant length of indwelling needle in operative state can be modified, inhibiting injury to patient.
摘要翻译：留置针，其由具有封闭端的主体构成，针尖在尖端形成尖锐边缘;管状毂，其保持针的近端并沿着主体滑动;保护盖，其可沿主体滑动并从该主体突出主体和弹性地装配在主体和保护盖之间的弹簧。当通过致动设置在主体上并且与保护盖相对于主体可缩回的杆来提升第一突起时，第一突起被容纳在通孔中并且按压与第二接合部分接合的保护盖的第二突起朝向内圆周，呈现操作状态。留置针在手术状态下的长度可以修改，抑制患者的伤害。

摘要： An indwelling needle 1 is composed of a cylindrical body 3, a needle 4 having a sharp edge 4a at a tip thereof, a cylindrical hub 5 which retains a proximal end of the needle 4 and which advances and retracts along the main body 3, and a protective cover 6 which advances and retracts along the main body 3 to project leftward, in the drawings, from the main body 3, and a spring 7 elastically installed between the hub 5 and the protective cover 6. A first engaging portion 11b of an actuating lever 11 provided on the body is engaged with a first projection 6a of the protective cover and a second through-hole 22b in the hub to allow a first retention mechanism A to retain the indwelling needle in a use state. The first engaging portion is moved upward to release the first retention mechanism. This separates the protective cover and the hub from each other under the elastic force of a spring. The protective cover and the hub are thus retained in a housed state by a second retention mechanism B and a third retention mechanism C, respectively.This configuration enables a reduction in the length of a member contacting a patient in the use state.
摘要翻译：留置针1由圆筒体3，尖端4a的针4，保持针4的近端并沿着主体3前进退出的圆筒状的毂5构成，以及沿着主体3前进和后退的保护罩6，从主体3向图中左侧突出，弹簧7弹性地安装在轮毂5和保护罩6之间。第一接合部分11b 设置在本体上的致动杆11与保护罩的第一突起6a和第二通孔22b接合在毂中，以允许第一保持机构A将留置针保持在使用状态。第一接合部分向上移动以释放第一保持机构。这在弹簧的弹力下将保护盖和轮毂彼此分开。保护罩和轮毂因此分别由第二保持机构B和第三保持机构C保持在容纳状态。这种构造使得能够在使用状态下减少与患者接触的部件的长度。

摘要： Indwelling needle includes a cylindrical body, a needle having a sharp edge at a tip thereof, a cylindrical hub retaining proximal end of needle and moveable along main body, a protective cover moveable along main body and projecting from main body, and a spring elastically installed between hub and protective cover. First engaging portion of actuating lever is provided on body engaged with first projection of protective cover and second through-hole in hub to allow first retention mechanism to retain indwelling needle in a use state. First engaging portion is moved upward to release first retention mechanism. This separates protective cover and hub from each other under elastic force of spring. Protective cover and hub are thus retained in a housed state by second retention mechanism and third retention mechanism, respectively. This configuration reduces length of member contacting patient in the use state.
