Fig. 2 is a schematic structural view of the retraction state of the safety syringe with a retractable needle point of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further explained below.
Referring to fig. 1 to 2, a safety syringe with a needle tip capable of repeatedly extending and retracting includes a syringe 10, a syringe 11, a syringe holder 12 and a syringe jacket 13, an outer sleeve 10a is sleeved on the syringe 10, a piston 10b and a core rod 10c fixed on the piston 10b are arranged in the syringe 10, one end of the core rod 10c extends outwards to the outside of the syringe 10, the syringe holder 12 is arranged in the syringe 10 and faces away from the piston 10b, the syringe 11 is fixed on the syringe holder 12, the syringe 11 and the syringe holder 12 are bonded by medical adhesive, the syringe jacket 13 is arranged at the front end of the syringe 10, and the syringe jacket 13 is arranged in parallel with a needle 11a of the syringe 11. An elastic member 20 is provided at an end of the needle holder 12 facing the piston 10a, and the elastic member 20 is preferably a stretch hose. The elastic member 20 is provided to float on the needle holder 12, and an opening/closing member 30 for controlling the expansion/contraction of the elastic member 20 is provided on a side portion of the needle holder 12.
The switch component 30 comprises a button 31 and a locking piece 32, the locking piece 32 is arranged on the button 31, one end of the button 31 is connected with the needle tube seat 12, the other end of the button 31 penetrates through the needle tube sleeve 13 to extend outwards, and the locking piece 32 is matched and connected with a locking piece 33 arranged on the inner wall of the needle tube sleeve 13. The button 31 has a spring 34 thereon, the spring 34 being connected to the needle hub 12. When the push button 31 is pushed, the lock member 32 is moved by separating from the lock member 33 by the spring 34 of the push button 31.
