技术领域technical field
本发明涉及料体注射领域，尤其涉及一种连续式注射装置。The invention relates to the field of material body injection, in particular to a continuous injection device.
背景技术Background technique
注射法是使用无菌注射器或输液器将药液直接注入动物体组织内、体腔或血管内的给药方法，是临床治疗上最常用的技术，具有确实、见效快的特点。当前多数的注射装置，每次注射完成，均需取下注射装置，从注入口重新抽入料体，然后进行注射，这样的注射装置注射效率比较低，每次加料也较为繁琐，同时不便于注射计量，对生产影响较大。Injection is a drug administration method in which a sterile syringe or infusion set is used to directly inject medicinal liquid into animal tissues, body cavities or blood vessels. Most of the current injection devices need to remove the injection device after each injection, re-inject the material from the injection port, and then inject. The injection efficiency of such injection devices is relatively low, and it is cumbersome to add materials each time, and it is inconvenient. Injection metering has a great impact on production.
