As shown in figures 1-4, the syringe for quickly recovering the needle cap comprises a cylinder body 2, a core bar 1, a piston 4, a needle 5 and a needle cap 6.
In order to solve the technical problem that the needle cap 6 is easy to lose and difficult to recover, the needle cap 6 is connected with the cylinder 2 into a whole through an elastic connecting piece 8. The elastic connecting piece 8 is a plastic spring or other elastic materials. One end of the elastic connecting piece 8 is connected with the needle cap 6, and the other end is connected with the top 9 of the cylinder body. When the needle cap 6 is sleeved on the needle head 5, the elastic connecting piece 8 is in a stretching state; when the needle cap 6 is pulled off, the needle cap 6 automatically retracts to the top part 9 of the barrel body, the needle cap 6 can be pressed conveniently during injection operation, and the injection process cannot be influenced.
In order to solve the problem that prevents to retrieve and recycle, the syringe still set up non return preforming 3 be equipped with the slotted hole that suits with non return preforming 3 thickness on the 2 lateral walls of barrel, non return preforming 3's bottom is moulded the system material through can breaking off and is connected with slotted hole edge sealing, non return preforming 3's top is equipped with spacing piece 302 for the position in restriction and the fixed non return preforming 3 embedding barrel 2. The upper ends of the two sides of the non-return pressing piece 3 are provided with anti-reset wedge-shaped protrusions 301, and the anti-reset wedge-shaped protrusions 301 are made of elastic materials. After injection operation, piston 4 is pushed to 2 bottoms of barrel, press non return preforming 3 to 2 interior imbeds of barrel, the plastic material disconnection of can breaking off of 3 bottoms of non return preforming and section of thick bamboo wall junction, non return preforming 3 then begins to imbed in barrel 2, then the protruding 301 by the section of thick bamboo wall compression of slotted hole both sides of the wedge that prevents resetting of 3 both sides of non return preforming, make non return preforming 3 imbed in barrel 2 smoothly, then prevent the protruding 301 reconversion of wedge that resets and block on the 2 inner walls of barrel of slotted hole both sides, thereby prevent that the people from for pulling up non return preforming 3 outward, further restrict non return preforming 3's fixed position. At this moment, non return preforming 3 just blocks in piston 4 upper end, prevents the piston 4 outwards pull to the realization prevents the mesh of reuse. The non-return pressure plate 3 can be designed as a square or a right triangle.
In order to solve the inconvenience brought to the injection operation due to dim environment, insufficient light and the like, a noctilucent film can be arranged at the bottom of the pintle 7 or the barrel body 2. The luminous film can play a role of supplementing a light source in a low-light environment, so that the direction and the position of the needle point are well indicated.
