Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be described below, apparent, as described herein is merely embodiments of the invention, not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0024] See Figure 1 to 6 The present invention provides a projectile injection device including the first syringe 1, the second needle 2 and the push rod 3, the second needle 2 is disposed inside the first pinch 1, and the push rod 3 is disposed in the first The two-pinch 2 is inside, and the first pinch 1 is used to mount the medical injection needle, and the first plunger 4 is mounted on the needle seat of the second pinch. The bottom of the push rod 3 is mounted with a second plunger 5. The second syringe 2 is tightened with the inner wall of the first plunger 4, and the second needle 2 can slide up and down in the first p...

Abstract

The invention relates to the field of medical equipment, in particular to a bolus injection device. The bolus injection device comprises a first needle cylinder, a second needle cylinder and a push rod, wherein the second needle cylinder is arranged in the first needle cylinder; the push rod is arranged in the second needle cylinder; a needle base of the first needle cylinder is used for installing a needle; a first plunger is installed on a needle base of the second needle cylinder; a second plunger is installed at the bottom of the push rod; the second needle cylinder is tightly attached to the inner wall of the first needle cylinder through the first plunger; the push rod is tightly attached to the inner wall of the second needle cylinder through the second plunger; a through hole is formed in the middle of the first plunger and allows the needle base of the second needle cylinder to be led in; a one-way valve is installed in the through hole; and an annular protruding part with a diameter smaller than the diameter of the through hole is arranged at the bottom of the first needle cylinder and serves as a control switch of the one-way valve. The bolus injection device is ingenious in design, reasonable in structure and low in manufacturing cost, bolus injection can be achieved, and the residual amount of the injector is reduced; and time for workers to receive radioactive medicine radiation is shortened, and remarkable popularization significance is achieved.

Description

Technical field [0001] The present invention relates to the field of medical equipment, and more particularly to a projectile injection device. Background technique [0002] As nuclear medicine is increasingly recognized, its unique "projectile" injection is also constantly improving. "Projectile" injection is a common technique in nuclear medicine imaging, refers to injecting high concentration of radioactive drugs into veins under high pressure, then rapidly decompression, small doses will enter to be tested in a group . At present, the commonly used "projectile" injection method is to extract tracer in ordinary disposable sterile syringe, and then release the pressure pulley after rapid injection. The defects present in the above methods are uniform flow standards; there is no uniform speed standard; the residual amount of the syringe is increased; it is not conducive to the standardization of technology. [0003] Therefore, it is necessary to solve the above technical problem...
