[0119] 首先,如图5A至图5E所示,其为本发明的具有闭锁针头安全盖的一次性注射器10在使用的前的整体示意图。 [0119] First, as shown in FIGS. 5A to 5E, the front latch having an overall schematic view of the needle safety cap 10 in disposable syringes which use the present invention. 根据本发明的实施例中,此种具有闭锁针头安全盖的一次性注射器10包含有活塞组件、固定套筒200、以及注射器本体400。 According to an embodiment of the present invention, such a lid having a latch needle safety disposable syringe comprises a piston assembly 10, the fixed sleeve 200, and the syringe body 400. 其中,上述的活塞组件包括:活塞臂100及活塞端300,而上述的固定套筒200设置于注射器本体400当中。 Wherein said piston assembly comprising: a piston arm 100 and the piston end 300, and said fixed sleeve 200 which is provided on the syringe body 400.

[0120] 根据本发明的实施例,活塞端300位于注射器本体400内部的前端上。 [0120] According to an embodiment of the present invention, the piston 300 is located on the distal end of the interior of the syringe body 400. 活塞臂100的杆件140卡合于活塞端300的基座320的容置空间321中。 The lever arm 100 of the piston 140 engages with the end of the base 300 of the piston accommodating space 321 in 320. 固定套筒200环绕设置于活塞立而300的关出尖纟而330的周围,并使得关出尖纟而330抵持于尖纟而凸缘122,由此使得活塞端300与活塞臂100固设在一起。 Fixed sleeve 200 disposed about the periphery 300 of the tip clearance of the piston 330 and Si stand, and such that tip off the Si and Si tip 330 abuts against the flange 122 to thereby end the piston 300 and the piston arm 100 Solid set up together.

[0121] 详细而言,如图6A至图6B所示,当使用者通过手持部110回拉活塞臂100时,在此情况下,由于图1C中的尖端凸缘122可卡合于突出尖端330,由此,使得活塞端300与图1A的活塞臂100固定在一起,而同时被回拉(即往图示下方的方向)。 [0121] Specifically, as shown in FIGS. 6A-6B, when the user pulled back by the holding portion 110 of the piston arm 100, in this case, since the tip of FIG. 1C flange 122 may be engaged with the projecting tip 330, whereby the piston end 300 of FIG. 1A piston arm 100 secured together while being pulled back (i.e., to the direction shown below). 此时,活塞端300的顶端310 —并推动固定套筒200,使得固定套筒200、活塞端300以及活塞臂100三者一起被拉动。 At this time, the piston ends 310,300 of the top - and push the retention sleeve 200, the sleeve 200 is fixed such that the piston end 300 and a piston arm 100 is pulled along the three.

[0122] 当固定套筒200在注射器本体400内往后移动后,固定套筒200的套筒凸肋225接触于注射器本体400的本体壁410。 [0122] When the fixed sleeve 200 moves backward within the syringe body 400, the fixed sleeve 225 of the sleeve rib 200 in contact with the body wall 400 of syringe body 410. 值得注意的是,根据本发明的实施例,一旦固定套筒200往后移动,则位于其上的套筒凸肋225与注射器本体400的本体壁410之间的摩擦力就会相对地大,而使得固定套筒200无法再次往前移动(即往图示上方的方向)。 It is noted that, according to embodiments of the present invention, once the fixed sleeve 200 is moved backward, which are located on the sleeve rib 225 and the frictional force between the syringe body 410 of the body wall 400 will be relatively large, It can not be fixed so that the sleeve 200 is again moved forward (i.e., toward the illustrated upward direction). 换言的,套筒凸肋225的设计用以限制固定套筒200无法被往前推进,但其仍可继续往后拉动。 In other words, the sleeve rib 225 is designed to limit the fixed sleeve 200 can not be moving forward, but it can continue to pull back.

[0123] 之后,若使用者持续回拉活塞臂100,则固定套筒200将一并随着活塞组件(包括活塞臂100与活塞300)而持续被往后拉动。 After [0123] If the user continued retraction of the piston arm 100, the sleeve 200 is fixed together with the piston assembly (100 comprises a piston and the piston arm 300) and continues to be pulled back.

[0124] 当固定套筒200退到注射器本体400的底部开口时,注射器本体400上的止挡块460将抵持住固定套筒200,使得固定套筒200无法继续往后移动。 [0124] When the fixing sleeve 200 retreated to the bottom opening of the syringe body 400, the stopper 460 on the syringe body 400 against the hold of the fixed sleeve 200, such that the mounting sleeve 200 can not continue to move back. 换言的,止挡块460使得固定套筒200无法自注射器本体400内退出。 In other words, the stopper 460 so that the fixing sleeve 200 can not be ejected from the syringe body 400. [0125] 在此情况下,如第6C图所示,固定套筒200被限制住而无法再次往前、或者往后移动,其原因在于固定套筒200被止挡块460所挡住,因此无法继续往后移动。 [0125] In this case, first as shown in FIG. 6C, the fixed sleeve 200 is locked and can not re-forward or backward movement, the reason that the mounting sleeve 200 is blocked by the stop block 460 can not be We continue to move backward. 并且,固定套筒200也因为套筒凸肋225的设计,而使得固定套筒200无法再次往前移动。 Further, because the design of the fixed sleeve 200 of the sleeve rib 225, such that the mounting sleeve 200 can not move forward again.

[0126] 续请参阅第6D图,由于此时的固定套筒200已经被限制住,而无法再往前、或往后移动了。 [0126] Continued See FIG. 6D, since in this case the fixed sleeve 200 has been locked, and can no longer move forward or backward moved. 因此,若使用者持续推动手持部110,在此情况下,将仅有活塞臂100可以继续往前移动,进一步地,也将带动活塞端上的突出尖端330自固定套筒200内被推出。 Thus, if the user continues to drive the handheld unit 110, in this case, only the piston arm 100 can continue to move forward, and further, will drive the piston protruding tip end 330 is pushed out from the fixed sleeve 200. 更进一步而言,当突出尖端330离开固定套筒200的套设范围后,如第6D图所示,突出尖端330将不再卡合于活塞臂100上的尖端凸缘122。 Still further, when the tip 330 protrudes from the fixed sleeve sleeved range 200, as first shown in FIG. 6D, the protruding tip 330 is no longer engaged with the tip of the flange 122 on the arm 100 of the piston. 不过,虽然如此,活塞端300仍可继续凭借与的接触的杆件140与关出尖〗而330的推动,而持续往如移动。 But, nevertheless, with the piston end 300 may continue to push the lever 140 in contact with the tip and off〗 and 330, such as to move continuously. [0127] 如第6E图所示,当活塞组件一路往前推进,最后活塞端300将被抵挡于注射器本体400接近针头处的前端处。 As shown in [0127] FIG. 6E as in the first, when the piston assembly moving forward all the way, the final resist piston end 300 is near the front end of the needle of the injector body at 400.

[0128] 此时,若使用者再一次地回拉活塞臂100,由于突出尖端330已不再卡合于尖端凸缘122,因此,如第6F图所示,活塞端300与活塞臂100 二者将开始分离。 [0128] At this time, if the user once again retraction of the piston arm 100, since the protruding tip 330 is no longer engaged with the tip of the flange 122, and therefore, as shown on FIG. 6F, an end of the piston 300 and the piston arm 100 two We will begin to separate.

[0129] 因此,当活塞端300与活塞臂100 二者分离之后,活塞臂100将无法再次结合于活塞端300。 [0129] Thus, when both ends of the piston 300 and the piston arm 100 is separated, the piston arm 100 will be unable to bind to the piston end 300 again. 换言的,如第6G图及第6H图所示,本发明提出的具有闭锁针头安全盖的一次性注射器10即无法再次地被重复使用。 In other words, as the first and second FIG. 6G 6H FIG, proposed by the present invention a disposable syringe needle safety cap latch 10 that is not reused again.

[0130] 详细而言,当突出尖端330 —旦退到固定套筒200的套设范围的外后,活塞端300即开始与活塞臂100分离。 [0130] Specifically, when the protruding tip 330-- retreated once after the outer sleeve is provided a fixed range of sleeve 200, i.e. piston end 300 and the piston arm 100 begin to separate. 并且,活塞端300与活塞臂100亦无法再次结合。 Further, the piston end 300 and the piston arm 100 will not be able bind again. 由此,使用者再也无法凭借拉动活塞臂100,来一并致动活塞端300。 Thus, the user can no longer be pulled with the plunger arm 100 to the actuator piston end 300 together.

[0131] 并且,在活塞端300与活塞臂100分离之后,活塞臂100上的使用指示器123即被显露出来。 [0131] and, after separation of the end of the piston 300 and the piston arm 100, 100 using a pointer 123 on the piston arm i.e. revealed. 使用者便可凭借判读使用指示器123,得知该注射器是否已经被使用过。 With the user can interpret the use of the indicator 123, to know whether the syringe has been used.

[0132] 其次,为扩大本发明的实际应用层面,产品设计者更可选择性地凭借设置多个套筒凸肋225,来控制注射器所应注射的药物用量。 [0132] Next, to expand the level of practical application of the present invention, product designers more selectively provided with a plurality of ribs of the sleeve 225, to control the amount of drug to be injected by the syringe. 举例而言,若注射器所需引入的药物用量,对应于注射器本体的管体积的25%,那么,套筒凸肋225可选择设置于对应固定套筒200的管体积25%的地方。 For example, if 25% of the required amount of the drug introduced in the syringe, the syringe body corresponding to the volume of the tube, then the sleeve rib 225 is provided to select the volume of the tube 200 corresponding to the fixed sleeve 25 percent place. 又,若注射器所需引入的药物用量,对应于注射器本体的管体积的50%,则另一个套筒凸肋225应设置于对应固定套筒200的管体积50%的地方,以控制固定套筒200行至套筒凸肋225所在处后即无法再次往前回推,并且,活塞端300在此时也开始与活塞臂100分离。 Further, if 50% of the required amount of the drug introduced in the syringe, the syringe body corresponding to the cylinder volume, the other sleeve rib 225 should be disposed in the cylinder volume corresponding to the fixed sleeve 200 where 50% to control the fixing sleeve cylinder line 200 to the sleeve 225 is located after the ribs can not be pushed back forward again, and the piston end 300 also begin to separate and the piston arm 100 at this time.
