[0002] As of my knowledge cutoff date of September 1, 2021, there is no specific liquid injection gun background technology widely referred to as a "safe liquid metered continuous injection gun". However, I can provide some general information about liquid injection, metered injection, and syringe safety. Liquid injection is a common medical practice used to deliver medications, nutritional solutions, or other therapeutic fluids into a patient's body. A syringe is a frequently used tool for accurately injecting liquids into the body. Measuring injection refers to accurately measuring and delivering a specific dose of liquid through a syringe. This is critical to ensuring that patients receive the correct dose of medication, especially in medical and drug therapy. Syringes need to be designed to be disposable to reduce the risk of cross infection. The syringe should have a leak-proof design to ensure that the drug or liquid does not leak before or during injection.

[0003] According to the public disclosure of the safe type quantitative continuous injection of liquid (publication number: CN 206534727 U), an injection gun body with a handle is provided with a liquid storage tank connected to the liquid outlet pipeline in the injection gun body on the top of the injection gun body, and a liquid filling port with an upper cover is provided on the top of the liquid storage tank; a touch screen is provided on the side wall of the injection gun body, and a PLC controller, a flow control motor and a rechargeable power supply are provided therein; a manually controlled injection valve is provided on the liquid outlet pipeline, and a pressing handle of the manually controlled injection valve extends downward out of the injection gun body; an injection needle that fits tightly with the liquid outlet of the liquid outlet pipeline is movably inserted at the front end muzzle of the injection gun body, and an anti-flying needle clamping piece for clamping the injection needle is movably provided on the outside of the injection needle; the liquid outlet end of the injection needle extends through the front end of the anti-flying needle clamping piece, and a card slot that matches the card tongue at the rear end of the anti-flying needle clamping piece is provided on the outside of the front end muzzle of the injection gun body. During use, the flow rate of the safety liquid cannot be adjusted according to the size of the experimental target, which needs to be improved. Utility Model Content
