[Abstract]:Needle-free injection is the technical process of injection by using the high-speed jet of the liquid into the injected body. With the promotion of clinical needs and the development of science and technology, needle free syringe technology has shown a vigorous development trend, the United States and Europe have been different types of commodities, the study of needle free injection in China has just started. At present, there is no domestic demand for products on the market. The main contents of this paper are as follows: 1. This paper introduces the existing syringe technology at home and abroad, summarizes the technical index and research and development route of the existing syringe. 2. According to the function, the syringe is divided into mechanical structure part, hydraulic circuit part and electrical control part. According to the analysis and the requirement to refine the structure, the key parameters are calculated theoretically, the product 3D model is designed, and the prototype of the design principle is simplified to verify the feasibility of the principle of the needle less syringe. 4. Based on the small hole injection model and liquid impact model designed by predecessors, the designed machine is simulated and the spray characteristic distribution for each high-pressure air spring is obtained. 5. The stability experiment, high speed camera experiment, injection bionic material experiment and in vitro pork injection experiment were carried out. Four experiments were carried out step by step, which gradually proved the stability of the principle prototype of the needle free syringe. The consistency of the model simulation data with the experimental data and the stability of the injection morphology are verified, and the conclusion that the injection depth increases with the increase of the injection power is verified. In this paper, the mechanical mechanism, electrical control, theoretical analysis of the injection process, processing and debugging of the prototype are designed, and a variety of experiments are carried out to verify the feasibility and reliability of the prototype, and the preliminary work of the new product development is completed. For the subsequent development of new products to establish a solid foundation.
