New Description·· 【New Technology Fields】 This creation is a structural improvement of the money-makeup. It is planted in (4) when the transfer is completed, the injection putter can be used to put the needle fox into the invisible injection. The rider needs to break the injection pusher to achieve a fast and safe syringe design. [Prior Art] According to the recent transmission of various kinds of diseases, such as A { D s and various fearful infections such as hepatitis _ have caused human miscellaneous, and these transmissible diseases have been rumored It will be life-threatening and even incurable (such as A! D s ), and in addition to the infection of body fluids, blood infections (such as blood transfusions) are also the main route. Because of this, most of the medical staff directly with this fiber rope 励 _ _ _ _ medical care for these patients is none other than the past ff can hear someone (4) after a patient is injected, accidentally hand The injection needle is stabbed and suffers from the same disease as the patient. Therefore, most of the current medical staff are quite afraid that this situation will happen to them, which will affect the morale of the medical staff. Therefore, it is safe. The design of the syringe. However, the patented safety syringe design is mostly in the factory. After the injection is completed, the injection push rod is pulled back to collect the needle into the syringe, and the injection push rod is broken and separated by the broken portion. However, although this design has a safety effect, it is necessary to break the injection push rod after each injection, which causes inconvenience in use, and the injection push rod and the syringe are separated and discarded after the break. The volume of waste has increased significantly. [New content] <Technical problems to be solved> M314613 The creator has more than (4) knowing the safety job design. (4) There are still problems that are difficult to solve: hope for lack of supply-improvement, and to solve these problems. Concentrate on thinking and materials, and comprehensively collect the results of the eve of the year _ material design, production and teaching expertise and practical experience and research results of the design of the final study of the creation of a safe, sub-, and Improvements to provide a safer and more convenient user 0 <Effects on the prior art > Advantages of this creation ·· Two == After the injection of the cartridge, the injection pusher is stretched backwards out of the syringe - after the length · ^ Easy to operate and scale. Return _ injection putter, 2 = Chuangjing completes the need to fold the gorge to shoot, Sister County needle is placed in the syringe, and then does not increase the medical waste _, so that the cost of processing medical waste is large Reduce the [common method] Shooting (4), the rod of the injection putter (4) (4 Ί, group is the axial track UU), on the injection putter (4), «at least - fishing (4 3 1) and make the elastic claw fishing (4 3 i ) through the sleeve ·, the main shot ^ have - the end with _ position (43), in the -4 = ((10) her coffee - 12) her coffe == Shot: M314613 The group is equipped with a leak-proof gasket (4 3 4) to achieve the effect of leak prevention.

At this time, the injection push rod (4) is pulled outward from the syringe (1). Push (2) with the needle (3) - and in her syringe (1), continue to slide the injection two: (1) outside the pull to make - ^ position (4 3 paste on the outer edge of the needle (1) end hole ((2) At this point, the pullback is shown), the shame is not allowed to be pushed into the lazy (1) (as in the third figure, the ▲ main shot putter (4) moves into the syringe (1), and then the needle (3) And the person who injects the injection (if the sputum is hidden in the syringe, and the injection pusher (1) is not needed again), the safety can be achieved (not shown in the figure), and the injection can be set up (4). For ribs (4 2 ), and this creation (10) (4) 1), the cerebral palsy shows that there is less - (four) corresponding to the elastic fishing (4) 2) (as shown in the fifth figure, on the phased parts (4 3) _ The positioning ring protrusion (4 3 3 ) is provided at the front of the injection push M314613 rod = inner hole - the heterocyclic groove (4) 2), and the pull-back positioning member (4 groups, and the left-hand push rod (4) ) When the front end hole reaches the positioning target.
