A spine image generating system based on an ultrasonic rubbing technology comprises a collecting unit and a processing unit. Ultrasonic rubbings are generated by the system based on ultrasonic imageswith two-dimensional spine surface structure characteristic outlines, and matched with a digital medical image outline, and thus a personalized spine surface topographic map which is consistent with an intraoperative position of a patient and updated in real time is obtained. A spine surgical navigation positioning system based on the spine image generating system comprises a navigation module andthe spine image generating system based on the ultrasonic rubbing technology. The spine surgical navigation positioning system can obtain the spine surface topographic map which is consistent with the intraoperative position of the patient and updated in real time, and can conduct real-time intraoperative navigation based on the spine surface topographic map. The spine image generating system based on the ultrasonic rubbing technology and the spine surgical navigation positioning system can greatly reduce the difficulty of a spinal operation, can achieve the operation auxiliary purposes of precise and nonradiative guided puncture, real-time navigation and being simple, convenient and reliable, and are particularly beneficial for application and popularization of a spinal minimally invasive surgery technology which is represented by a spine endoscopy to primary health care institutions.

The invention relates to a closed-loop expectoration method for automatically titrating the pressure of expectoration, comprising S1, setting the reference value C2 of the user's negative pressure phase flow-volume ring area F-V ring area; S2, calculating the user's The actual value R2 of the negative pressure phase F-V ring area; S3, compare the reference value C2 of the negative pressure phase F-V ring area, and the actual value R2 of the negative pressure phase flow-volume ring area to adjust the negative phase pressure E-P and / or normal phase pressure I‑P. The present invention also proposes a closed-loop expectoration system for automatically titrating the pressure of expectoration, including: a reference value setting module, which sets the reference value C2 of the negative pressure phase flow-volume ring area F-V ring area; the actual value calculation module , monitor and calculate the actual value R2 of the negative pressure phase F-V ring area; the comparison module compares the reference value C2 and the actual value R2; the adjustment module adjusts the negative phase pressure E-P and the positive phase based on the results of the comparison module Pressure I‑P. The expectoration method and system of the present invention ensure safer and more effective expectoration.

The invention discloses a portable intelligent multi-probe TCM pulse diagnosis instrument, which includes a frame assembly, a probe assembly and an information collection system, wherein the frame assembly includes a pulse pillow part and a frame part, and the probe assembly and the frame part The three-degree-of-freedom movement of the probe assembly in the plane perpendicular to the arm is realized by a kinematic mechanism. The arm is placed on the pulse-occipital part, and the placement position and angle can be adjusted. Through the image acquisition module and image analysis and positioning module in the information acquisition system, the acquisition and positioning of the arm position and posture are realized. The pulse diagnosis instrument can automatically find the pulse position, automatically apply pressure and automatically collect the pulse signal according to the method of "five belts, six areas and seven floors". Reproducible, portable and flexible; it can be used for early warning and diagnosis of clinical diseases, effectively solving the problems of low acquisition accuracy, incomplete acquisition signals, and bulky body of similar instruments.
