为了减少在治疗中使用普通注射针头带来的不便，在临床使用的普遍注射针头基础上，我们研制了球阀单流向注射针头，可以按照治疗的需要使液体和气体顺利通过，不发生逆流。回结构原理特种医用针头是将普通注射针头的针座部分适当加长，增加的长度为其直径的2倍时即可满足需要。
In order to reduce the inconvenience caused by the use of common injection needles in the treatment, based on the commonly used injection needles used in the clinic, we developed a ball-valve single-flow injection needle that can smoothly pass the liquid and gas according to the needs of the treatment, and no backflow occurs. Back to structural principle The special medical needle is to properly lengthen the needle seat part of a common injection needle, and the increased length is 2 times the diameter to meet the needs.
