Objective: To develop a portable microcomputer infusion pump for clinical constant pressure skin dilatation. Methods: Using a linear peristaltic liquid drive and microcomputer automatic control technology, a portable infusion pump consisting of modules was designed and manufactured to perform seismic, fatigue, and sensitivity tests. Clinical applications were also observed. Results: HY-III intelligent constant pressure infusion pump volume 10.5cm × 12.1cm × 6.5cm, net weight 900g. Press the menu prompts to set the operating parameters, the maximum flow rate of the micropump is 1000mL/h, the shortest start-up time is 1s, and the pumping liquid is 0.55mL. The laboratory test passed the test, and 9 cases of constant pressure skin dilatation were successfully performed. Conclusion: HY-III intelligent constant pressure infusion pump is small, light weight and easy to carry. The machine is stable in operation and can be used for the brief introduction of the author: Li Jiang, male, 37 years old.
