Embodiment Construction

[0028] Such as figure 2 As shown, hold the handle 11 of the tenderness mechanical tester, and place the measuring device on the upper surface of the patient's skin, see figure 1 , so that the indenter 1 touches the surface of the human skin and keeps it perpendicular to the skin surface, and presses down on the measuring device, the indenter 1 will move down with the measuring device, causing muscle deformation, and due to the obstruction of the skin surface, the sleeve The sleeve 2 will bounce upwards, and the displacement sensor 3 connected to the sleeve 2 can detect the displacement change of the sleeve 2 at any time. This displacement value is the deformation of the skin surface. The pressure sensor 7 connected to the sleeve 2 can detect the displacement of the sleeve 2 at any time. The pressure changes, and this pressure value can reflect the tension on the skin surface. The above two physical quantities are transmitted to the digital display screen 10 through the displ...

Abstract

The invention provides a pressing pain mechanics tester. The pressing pain mechanics tester comprises a shell, a digital display screen and a measuring device, wherein the measuring device is arrange inside the shell, the top of the shell is provided with the digital display screen having a data processing function, and the measuring device measures pressure and displacement and transmits signals to the digital display screen. A pressing pain value is calculated on the basis of a viscoelastic model of soft tissue of the human body with large deformation, and a measured value is displayed on the digital display screen through the measuring device. The pressing pain mechanics tester overcomes the defect that detection of a muscle state of the human body is affected by subjective perception of a patient in the prior art, and a pain state of a muscle of the human body can be recorded objectively and quantificationally.

Description

technical field [0001] The invention relates to a tenderness mechanics tester, which belongs to the technical field of surgical medical instruments. Background technique [0002] Pain is a common clinical symptom that brings many negative impacts on patients' lives. At present, clinical pain diagnosis mainly relies on asking patients about their subjective pain perception. There is no reliable means to quantify pain value, and the accuracy is poor. [0003] The internationally used psychological pain scale can obtain the patient's subjective pain information, but it is greatly affected by the patient's subjective pain when used in clinical diagnosis. There is also a method that researchers use functional MRI to scan the brain to measure a person's true pain level, but this method is expensive and complicated to operate. Contents of the invention [0004] The purpose of the present invention is to provide a mechanical tester that is not affected by the patient's subjectiv...
