Problems solved by technology

[0003] The existing LDF probe is small and not easy to hold; and the LED probe needs to be disinfected every time it is used to prevent cross-infection. Disinfection may damage the LDF probe or affect the accuracy of the test results. Bits are relatively less stable to some extent will affect the detection results

Embodiment Construction

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0031] Such as figure 1 and figure 2 As shown, a laser Doppler blood flow detector probe includes a probe body 1, one end of the probe body is connected to the detector; the length of the probe body 1 is 1.2cm-1.7cm, and the A sleeve 2 is sleeved on the probe body 1 . The length of the probe body 1 is 1.2cm-1.7cm, which is more suitable for detecting teeth, so as to prevent the probe from being too long to be perpendicular to the tooth surface when the probe is in contact with the tooth surface during the detection process. Tube 2 is convenient to hold. The outer diameter of the sleeve 2 is 0.8cm-1.2cm. Easy to hold. The sleeve 2 is detachably connected to the probe body 1 . The sleeve 2 adopts a disposable d...

Abstract

The invention discloses a laser Doppler blood flower detector probe which comprises a cylindrical probe body, wherein a sleeve is in sleeving connection to the probe body, the outer diameter of the sleeve is 0.8cm to 1.2cm, a plurality of protruded points are distributed on the surface of the sleeve, the sleeve is in sleeving connection to a rear section of the probe body, a protection film in fit with the outer surface of the probe body is arranged on the outer surface of a front section of the probe body, the protection film is made of a transparent material, the protection film is in a sleeve shape, one end of the sleeve shape is open, one end of the sleeve is closed, the protection film is in sleeving connection to the front section of the probe body, a plurality of thorn protrusions are arranged on the front end face of the sleeve, and the number of the thorn protrusions is 3 to 4. The laser Doppler blood flower detector probe has the advantages of convenience in holding, benefit to reinforcing retention, good practicability and stability and further ability in effectively preventing damage caused by sterilizing to the probe.

Description

technical field [0001] The invention relates to a laser Doppler blood flow detector, in particular to a laser Doppler blood flow detector probe. Background technique [0002] LDF is a new technology for oral microcirculation detection. Traditional LDF is mainly used for microcirculation blood flow monitoring of tissues and organs such as skin, muscle, transplanted flaps and kidneys. Its main advantages are painless, non-invasive, stable and repeatable. The test results are accurate and objective, can be detected continuously, and can reflect instantaneous changes in microcirculatory blood flow. Its high accuracy and specificity has been recognized by more and more scholars at home and abroad, and it can play an important role in the detection of dental pulp vitality. [0003] The existing LDF probe is small and not easy to hold; and the LED probe needs to be disinfected every time to prevent cross-infection. Disinfection may damage the LDF probe or affect the accuracy of the...
