For example, the breast cancer drug fulvestrant, because it contains castor oil, can be so thick that nurses struggle to inject it
Once the hand slips due to too much force, it is especially easy to cause the needle to move and cause unnecessary puncture injuries

Embodiment Construction
[0025] Below, the syringe of the present invention will be described in detail in conjunction with the accompanying drawings.
[0026] The syringe for viscous liquid medicine of the present invention comprises: a cylinder body 10 , a piston member 20 , and a steel needle 30 .
[0027] The cylinder 10 is formed with an air inlet (not shown) and a circular hole 13 at its second end, and an internal thread is formed on the inner peripheral wall of the circular hole 13; the cylinder can form a reinforcing platform 12 around the circular hole 13 to Strengthen the robustness of the circular hole 13.
[0028] The cylinder body 10 is formed with a steel needle base 15 outside the side wall of its first end, and the first end of the steel needle base 15 is formed with a silicone tube needle 17; a steel needle joint hole 19 is formed in the steel needle base; the steel needle joint hole 19 communicates with the silicone tube needle 17; a connection through hole 16 is formed close to th...

The invention discloses an injection syringe for viscous liquid. The injection syringe comprises a cylinder block, a piston component and a steel needle; an air inlet hole and a circular hole are formed in a second end of the cylinder block; an inner thread is formed on the inner peripheral wall of the circular hole; a steel needle base is formed outside the side wall of a first end of the cylinder block; a silicone tubular needle is formed at the first end of the steel needle base; a steel needle coupling hole is formed in the steel needle base; the steel needle coupling hole communicates with the silicone tubular needle; a connecting through hole clings to the inner side of the first end of the cylinder block; the connecting through hole communicates the inside of the cylinder block withthe steel needle coupling hole; a piston head is rotatably coupled to the first end of a piston rod by taking the piston rod as an axis; a wheel-shaped handle is fixedly formed at the second end of the piston rod; an outer thread is formed on the rod body of the piston rod; the piston rod extends from the circular hole of the second end of the cylinder block to the outside; the steel needle is inserted into the steel needle coupling hole and the silicone tubular needle; a tip, extending to the outside of the silicone tubular needle, is formed in the first end of the steel needle; and the second end of the steel needle extends to the outside of the second end of the steel needle coupling hole.
Description
technical field [0001] The invention relates to a syringe, in particular to a syringe for viscous medicinal liquid. Background technique [0002] When injecting viscous medicinal liquid, it is difficult to push the medicinal liquid out of the syringe due to the viscosity of the medicinal liquid. For example, the breast cancer drug fulvestrant, because it contains castor oil, can be very viscous, and nurses struggle to inject it. Once the hand slips due to too much force, it is particularly easy to cause the needle to move and cause unnecessary puncture injuries. Contents of the invention [0003] In view of the above problems, the present invention aims to provide a syringe suitable for viscous medicines, which can be smoothly pushed out from the barrel of the syringe without unnecessary needle stick injuries. [0004] The syringe for viscous liquid medicine of the present invention comprises: a cylinder body, a piston member, and a steel needle; [0005] The cylinder b...
