Dentin permeability detection device

牙本质通透性检测装置

Abstract

The utility model discloses a dentin permeability detection device which comprises a pressure bottle, a pressure conversion container, a micro tube, an injection bubble device and a dentin fixing device, wherein an air inlet tube is arranged between the pressure bottle and the pressure conversion container; an air inlet pressure gauge valve is arranged on the air inlet tube; a first water outlet tube is arranged between the pressure conversion container and one end of the micro tube; a water outlet pressure gauge valve is arranged on the first water outlet tube; a second water outlet tube is arranged between the other end of the micro tube and a sample fixing device; the injection bubble device is arranged below the second water outlet tube and is communicated with the second water outlet tube; the sampling fixing device is provided with a sample groove; the sample groove is communicated with the second water outlet tube. The dentin permeability detection device overcomes the defects of a conventional dentin permeability detection device that great measurement errors and verification result errors can be caused as air inlet pressure can not be determined and the position of dentin is not fixed, and has the advantages that the air inlet pressure can be adjusted, the position of dentin is fixed, and the measurement error and verification result error are small.
本实用新型公开了一种牙本质通透性检测装置,包括压力瓶、压力转换容器、微量管、注射气泡装置和牙本质固定装置;压力瓶与压力转换容器之间设有进气管,进气管上设有进气压力表阀门;压力转换容器与微量管的一端之间设有第一出水管,第一出水管上设有出水压力表阀门;微量管的另一端与样本固定装置之间设有第二出水管,注射气泡装置设于第二出水管的下方且相连通,样本固定装置设有样品槽,样品槽与第二出水管连通。本实用新型克服了现有的牙本质通透性检测装置进气压力无法确定,牙本质位置不固定,致测量误差大,验证效果误差大的缺陷,提供一种进气压力可调节,牙本质位置固定,测量误差小,验证效果误差小的牙本质通透性检测装置。
