Is the indwelling needle for children the same as that for adults?

Same. According to the information of Inquiry 39 Health Network, the model of children's indwelling needle is the same as that of adults, but its efficacy is different. Indwelling needle refers to intravascular indwelling needle, which consists of sheath, catheter assembly (including catheter, wedge and catheter seat), needle assembly (including needle tube and needle seat) and air plug.
