The present application relates to the technical fields of deep vein catheterization infusion, in particular to a constant temperature control speed device for deep vein catheterization infusion, comprising an infusion catheter head and an infusion tube, one side of the infusion catheter head is fixedly connected with one end of the infusion tube. The present application sets a piston frame structure with spiral flow guide grooves inside the infusion tube, changes the fluid dynamics behavior of traditional plunger type propulsion, when the piston frame reciprocates, the liquid medicine forms spiral jet flow under the guidance of the spiral flow guide grooves, forced fluid generates circumferential rotation, effectively destroys the stationary state of the pipe wall boundary layer, converts the axial thrust into rotational shear force, not only reduces the flow resistance, but also eliminates the stagnant zone at the front end of the piston, realizes uniform delivery of the whole cross section, makes the liquid medicine always maintain a dynamic mixing state during the pushing process, avoids density stratification and sedimentation, especially suitable for the infusion of fat emulsion, amino acid and other easily separated nutrient solutions, greatly improves the stability of the infusion.

This invention discloses a parenteral nutrition solution preparation and delivery device, comprising a first mixing component, a second mixing component, a third mixing component, a secondary mixing chamber, a transfer chamber, a tertiary mixing chamber, and a frame. The first mixing component mixes phosphate-free electrolytes, water-soluble vitamins, and trace elements into a compound amino acid solution. The second mixing component mixes phosphates into a glucose solution. The third mixing component mixes fat-soluble vitamins into a fat emulsion. The secondary mixing chamber further mixes the mixed amino acid solution and the mixed glucose solution. The transfer chamber agitates the mixed solution to ensure thorough mixing. The tertiary mixing chamber adds the fat emulsion containing fat-soluble and water-soluble vitamins to the amino acid and glucose mixture. This device, through the coordinated operation of its components, enables the rapid and accurate preparation of large quantities of parenteral nutrition solution, and the preparation process is carried out within a sealed container, preventing contamination of the nutrient solution by the external environment.
