Description
Technical field:
This utility model relates to disposable syringe, relates more specifically to a kind of damage formula disposable syringe that is applicable to injection high price medicine.
Background technology:
The syringe of using always does not all have and effectively damages device at present, the probability of using the back existence to reuse, and this product has pressure damage device, and can in use reach the pressure damage, stop repeatedly to use.
Summary of the invention:
This utility model provides a kind of damage formula disposable syringe, and the design has guaranteed that from structure syringe can only use once, damages at once after finishing using, and has overcome the shortcoming of above-mentioned disposable syringe.The technical solution of the utility model is: damage formula disposable syringe, comprise: the needle tubing of a cylindrical shell, cylinder top and needle holder and intravital push rod of tube and packed-piston, it is characterized in that: needle tubing is fixed in the needle holder, and its two ends exceed needle holder, and needle holder places in the cylindrical shell upper end, its peripheral hardware one needle guard, the top of packed-piston is provided with endoporus, and packed-piston is inserted in the forward circle of push rod to be buckled, and its endoporus communicates with the circle button, push rod places in the cylindrical shell, and a push rod sheath is established at its rear portion.This utility model is behind liquid medicine injection, not only medicinal liquid can all inject in patient's body, and the needle tubing of needle holder lower end has also penetrated the endoporus of packed-piston, make it to lose sealing, reach the purpose of forcing damage, that this product also has is rational in infrastructure, easy to assembly, with low cost, medicine to the greatest extent pin characteristics such as ruin, especially be fit to injection high price medicine, very easily promote the use of.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a collapse state structural representation of the present utility model.
Wherein: 1 cylindrical shell, 2 needle tubings, 3 needle holder, 4 push rods, 5 packed-pistons, 6 needle guards, 7 endoporus, 8 circle buttons, 9 push rod sheaths
The specific embodiment:
As shown in Figure 1: this utility model comprises: a cylindrical shell 1, push rod 4 and packed-piston 5 in cylindrical shell 1 vertical needle tubing 2 and needle holder 3 and the cylindrical shell 1, needle tubing 2 is fixed in the needle holder 3, its two ends exceed needle holder 3, needle holder 3 places in cylindrical shell 1 upper end, its peripheral hardware one needle guard 6, the top of packed-piston 5 is provided with 7, packed-piston 5 is inserted on the push rod 4 forward circle buttons 8, its endoporus 7 communicates with 8, push rod 4 places in the cylindrical shell 1, a push rod sheath 9 is established at its rear portion, and the length that the lower end of needle tubing 2 exceeds needle holder 3 is the 0.1-55 millimeter, and the external diameter of needle holder 3 lower ends is greater than the internal diameter of cylindrical shell 1 upper end.
As shown in Figure 1 and Figure 2: during this utility model work, as long as push rod 4 is firmly pushed ahead, medicinal liquid in the cylindrical shell 1 is discharged from needle tubing 2, when packed-piston 5 arrives at the upper end of cylindrical shell 1, medicinal liquid in the cylindrical shell 1 drains, the top that this moment, packed-piston 5 was worn out in needle holder 3 interior needle tubing 2 lower ends, and insertion endoporus 7, thereby destroyed the sealing property of packed-piston 5, make it to keep sealing state again, thereby reach the purpose of forcing damage, again cylindrical shell 1 inner push-rod 4 is pulled out half, be broken push rod 4, reach the purpose of thorough damage.
