DECONTAMINATION /STERILIZATION OF DENTAL HANDPIECES

Novaflux计划开发一种用于牙科手机(DHS)的低温灭菌技术，该技术基于其专利的两相流体动力学工艺。建议的流程包括使用由Novaflux特别配制的空气和液体两相混合物来清洁和消毒国土安全部的内部通道。所提出的装置旨在将两相流输送到内部通道，同时在国土安全部的外表面喷洒清洁和灭菌溶液。初步结果表明，该工艺在温度低于60℃，循环时间为5-10分钟的条件下，对接种了4x10[6]嗜热脂肪芽胞的DHS内通道和外表面都进行了灭菌。拟议的研究有两个具体目标：(L)开发和(2)在实验室和贝勒大学牙科诊所使用嗜热脂肪芽孢杆菌验证卫生署冷灭菌过程。这项拟议的技术有望延长手机的使用寿命，降低维修成本，并保持手机的清洁度和性能。建议的商业应用：1.为手机提供低温灭菌的装置。2.技术在DUWL和其他牙科工具中的应用。3.将技术外推到医疗和工业领域使用的其他清洁工艺。

Novaflux plans to develop a low-temperature sterilization technology for dental handpieces (DHs) based on its patented two-phase fluid dynamics process. The proposed process consists of cleaning and sterilizing the internal channels of DHs using a two-phase mixture of air and liquid compositions specially formulated by Novaflux. The proposed device is designed to deliver two-phase flow to the internal channels and simultaneously spray the external surfaces of the DHs with cleaning and sterilizing solutions. Preliminary results show that the process sterilized both the internal channels and exterior surfaces of DHs inoculated with 4x10[6] of Bacillus Stearothermophilus spores at a temperature less than 60 degrees C and a cycle time of 5-10 minutes. The proposed study has two specific aims: (l) develop and (2) validate the DH cold sterilization process using the Bacillus Stearothermophilus in a laboratory, and in a dental clinic at Baylor University. The proposed technology is expected to increase handpiece service life, lower repair costs, and maintain handpiece cleanliness and performance. PROPOSED COMMERCIAL APPLICATIONS: 1. Device providing low temperature sterilization for handpieces. 2. Application of technology to DUWL's and other dental tools. 3. Extrapolation of technology to other cleaning processes used in medical and industrial areas.
