Embodiment Construction

[0022] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0023] like Figure 1-3 As shown, the present invention provides a technical solution: a radiopharmaceutical injection device for nuclear medicine, comprising a syringe 1, a protective cover 5 is provided on the outer surface of the syringe 1, a scale 17 is provided on the front of the syringe 1, and a pull rod The left end of 3 is provided with a push plate 4. By setting the scale 17, it is convenient for the staff to precisely control the injection volume of the medicine. The inner wall of the injection cylinder 1 is provided with a piston plate 2, and the outer surface of the piston plate 2 is provided with a gasket. The outer surface is provided with an anti-slip sleeve 9. By setting the anti-slip sleeve 9, it can prevent the staff from sliding freely during the rotation of the rotating sleeve 8. The left side of the piston plate 2 is fixedly c...

Abstract

The invention discloses a radiopharmaceutical injection device for nuclear medicine departments, and belongs to the technical field of medical treatment. The injection device includes an injection cylinder; the inner wall of the injection cylinder is provided with a piston plate; the left side surface of the piston plate is fixedly connected to the right end of a pulling rod; the injection cylinder communicates with a syringe needle; and the right side surface of the injection cylinder is provided with a bearing. Through the mutual cooperation of a rotating sleeve, the bearing, a movable sleeve, an external thread, an internal thread and a rubber pad, the movable sleeve and the rubber pad can be controlled to move right by rotating the rotating sleeve so as to shield the syringe needle; when the device is used to inject, the movable sleeve and the rubber pad can be driven to move to appropriate positions by directly rotating the rotating sleeve; and the movable sleeve and the rubber pad can prevent the syringe needle from randomly shaking or tilting in the body of a patient, so that good protection effects on the syringe needle can be achieved to a certain extent, and injection canbe guaranteed to successfully and stably carry out.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a radiopharmaceutical injection device for nuclear medicine. Background technique [0002] In existing nuclear medicine, syringes are used to inject drugs into patients. However, during the operation of the injection device, the staff may shake or tilt their hands due to the long injection time, causing the needle to penetrate the blood vessel. At the same time, when the injection device accidentally falls to the ground It may cause the needle to be bent and damaged, which will affect the smooth and normal progress of the injection process. Contents of the invention [0003] (1) Solved technical problems [0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a radiopharmaceutical injection device for nuclear medicine, which solves the problem that the needle may tilt or shake during the injection process of the existing inje...
