Abstract

The utility model relates to a medical apparatus, in particular to an indwelling needle capable of being operated with one hand. The indwelling needle comprises first casing tubing, indwelling needle tubing, second casing tubing, a fixation removing unit, a seal tampon, a connection tampon, a bottom block, a spring, flow guide tubing, a needle wing and a puncture needle. The bottom end of the indwelling needle is fixedly connected with the first casing tubing; the first casing tubing is arranged in the second casing tubing in a penetration mode; the seal tampon is arranged in the first casing tubing in a penetration mode and fixedly connected with the first casing tubing; the connection tampon is arranged in the first casing tubing in a penetration mode and fixedly connected to the bottom end of the first casing tubing; the bottom block is arranged in the second casing tubing in a penetration mode and fixedly connected to the bottom end of the second casing tubing; the spring is arranged between the connection tampon and the bottom block and in a compression state when the spring is not used; the flow guide tubing is communicated with an inner cavity of the first casing tubing; the needle wing is detachably connected to the bottom end of the second casing tubing; and the bottom end of the puncture needle is fixedly connected with the needle wing, and the puncture needle penetrates into the indwelling needle tubing, the seal tampon, the connection tampon and the bottom block. The indwelling needle capable of being operated with one hand overcomes defects that traditional indwelling needles cannot be operated with one hand, operation difficulties are large and the like, and certain advantages are produced.

Description
