AI Technical Summary

Technical Problem

Traditional disinfection methods are inefficient when treating patients' skin wounds, and existing treatments such as stem cell therapy have problems such as high cost, long time, and susceptibility to infection. Furthermore, temperature control during cell growth in vitro has a significant impact on cell function and survival rate.

Method used

An application device is used to apply an electrospinning treatment solution, including an application device housing, a rotatable needle, a motor, a pressure pump, and an electrospinning fan. The treatment solution, such as a mixture of disinfectant and stem cells, is formed into an electrospinning fiber pad through electrospinning technology and applied evenly to the treatment site.

Benefits of technology

It achieves efficient and uniform application to the treatment site, improves cell survival rate and treatment effect, reduces infection risk, and lowers treatment cost and time.

Abstract

An applicator for applying a therapeutic solution to a treatment site of a patient is disclosed. The applicator can include an applicator housing including a therapeutic solution reservoir. A cartridge can be removably disposed within the housing. The cartridge can be in fluid communication with the therapeutic solution reservoir when disposed within the housing. The cartridge can include an electrostatic module for electrostatically charging the therapeutic solution in the therapeutic solution reservoir; and a nozzle for applying the therapeutic solution.
