Problems solved by technology
[0003] When the traditional medical syringe is not in use, the injection needle will still be tightly inserted on the end of the syringe, resulting in the length of the entire syringe being too long, which will not only take up a large storage space, but will also It is easy to touch the injection needle by mistake, which affects the installation stability between the injection needle and the syringe in the unopened syringe

Embodiment Construction
[0034] The following is attached figure 1 - attached Figure 4 , the specific implementation manner of the present invention will be further described in detail, so as to make the technical solution of the present invention easier to understand and grasp.
[0035] A medical foldable injection syringe, comprising a syringe 1, an injection needle 2, an injection push rod 3 installed in the syringe 1, a rubber stopper 4 is installed at the end of the injection push rod 3, and the periphery of the rubber stopper 4 is in contact with the injection barrel 1 is in conflict with the inner cylinder wall. An insertion hole 5 is provided at the end of the injection barrel 1 , and a ring-shaped boss can extend outward from the opening of the insertion hole 5 away from the injection push rod 3 . The injection push rod 3 can be pushed, and the injection liquid in the injection barrel 1 can be squeezed out from the insertion hole 5 and the injection needle 2 in sequence.

The invention provides a medical folding type injection needle cylinder. The medical folding type injection needle cylinder comprises an injection cylinder, an injection needle head, an injection pushrod mounted in the injection cylinder, and a mounting seat, wherein a rubber plug is mounted at the end of the injection push rod; the periphery of the rubber plug is propped to the inner cylinder wall of the injection cylinder; an inserting hole is formed in the end of the injection cylinder; the side wall of the mounting seat is hinged to the outer cylinder wall of the injection cylinder; the injection needle head is mounted on the mounting seat; a mounting sleeve is arranged at the end of the injection needle head; a clamping part is arranged on the outer cylinder wall of the injection cylinder; and when the mounting seat rotates around a hinging shaft, the mounting sleeve on the injection needle head can be inserted in the inserting hole, or the injection needle head is clamped to a clamping part, and is attached to the outer cylinder wall of the injection cylinder. When the medical folding type injection needle cylinder is not used, the injection needle head can be folded to be attached to the outer cylinder wall of the injection cylinder, so that saving storing space is facilitated, and the subsequent mounting stability between the injection needle head and the injection cylinder is not liable to influence.
Description
technical field [0001] The invention relates to the technical field of medical injection syringes, in particular to a medical folding injection syringe. Background technique [0002] Medical injection syringes usually include a syringe and an injection push rod installed in the syringe. A rubber stopper is installed at the end of the injection push rod. The periphery of the rubber stopper conflicts with the inner wall of the syringe. Injection needle; by pushing and pulling the syringe, the injection liquid can be sucked into the syringe or ejected from the injection needle. [0003] When the traditional medical syringe is not in use, the injection needle will still be tightly inserted on the end of the syringe, resulting in the length of the entire syringe being too long, which will not only take up a large storage space, but will also It is easy to touch the injection needle by mistake, which affects the installation stability between the injection needle and the injectio...
