The invention provides an injection device provided with a metering structure and used for intravenous nutrition injection for neonatal treatment. The injection device comprises: an injection cylinder; and an injection assembly, wherein the injection assembly slides on the inner wall of the injection cylinder. According to the invention, the injection device provided with the metering structure and used for intravenous nutrition injection for neonatal treatment has the advantages that the injection cylinder is connected with a retention needle on the vein of a neonatal, a nutrition solution in the injection cylinder is conveyed into the vein of the neonatal through the injection assembly, the nutrition solution is stored through the quantifying assembly, the nutrition solution in the quantifying assembly is quantitatively conveyed into the injection cylinder through the control assembly and the clamping assembly to achieve the quantitative input of the nutrition solution, the control assembly is limited through the limiting assembly so as to make the control assembly stably move in the quantifying assembly, and the quantifying assembly is fixed to the injection cylinder through the positioning assembly so as to improve the stability of the device, so that the operation is convenient.
Description
technical field [0001] The invention relates to the field of medical injection equipment, in particular to an injection device with a metering structure for intravenous nutrition injection for neonatal treatment. Background technique [0002] A syringe is an instrument used to inject liquids. The traditional syringe mainly includes a syringe and a push rod that is slidably inserted into the syringe through a sealing plug. When in use, the sealing plug in the syringe is driven to move axially by pushing and pulling the push rod. , so as to realize the function of suction and injection, and the operation is very simple. [0003] Newborns will use syringes when they are treated in the hospital, but the existing syringes lack a metering device when they are used. When giving nutritional injections to newborns, medical staff need to observe the graduation line of the syringe every time to control the amount of inhalation. Repeated use causes medical staff to be easily fatigued, ...
