Problems solved by technology

However, this method relies heavily on the doctor's experience, and the judgment of the patient's swelling degree is too subjective, and there is no unified classification and quantification standard for the swelling degree, which leads to the occurrence of different diagnoses for the same patient by different doctors, which damages the medical system. The scientific nature of technology reduces the trust of patients

Embodiment 1

[0044] Such as figure 1 As shown, it is a schematic structural diagram of a test device for measuring muscle or soft tissue hardness provided by an embodiment of the present invention, and the device includes:

[0045] Balloon cuff module to provide the constant back pressure needed to measure muscle or soft tissue stiffness;

[0046] Raised bladder module for applying pressure to swollen areas;

[0047] The measurement and control integration module is used to controllably inflate and pressurize the airbag cuff module and the raised airbag module, and measure and display the real-time signal of the flexible bending sensor.

[0048] In the embodiment of the present invention, in order to control the degree of pressing of the air bag to be consistent during measurement, the inflation pressure of the air bag cuff module and the raised air bag module must be kept constant, and the swelling lesion can be consistent with the raised air bag during measurement. Appropriate degree o...

Embodiment 2

[0099] Such as Figure 4 As shown, it is a schematic structural diagram of another test device for measuring muscle or soft tissue hardness provided by an embodiment of the present invention. The device may include: a weight module, an airbag deformation indenter module, a measurement and control integration module, two wing modules and a housing.

[0100] In a specific embodiment, the housing is detachable to facilitate maintenance of the original components of the testing device. And there is an opening for charging, and a structural support for installing the measurement and control integrated module; there is a structural support for fixing the airbag deformation indenter module, so that the relative position of the airbag 39 remains stable during the test without sliding. Grooves for installing the inflation conduit 36 ​​and the lead wire 35 are arranged on the inner wall.

[0101] In a specific embodiment, the load-bearing module is filled with polyether ether ketone, w...

Abstract

The embodiments of the present invention relate to a testing device and method for measuring hardness of muscles or soft tissues. The device comprises an air bag cuff module used for providing constant backpressure required by measuring the hardness of the muscles or soft tissues, raised air bag modules used for applying pressures to swollen areas and a measurement and control integrated module used for performing controllable inflation and pressurization on the air bag cuff module and the raised air bag modules, and measuring and displaying real-time signals of flexible bending sensors.

Description

technical field [0001] The embodiments of the present invention relate to the interdisciplinary technical field of medicine and mechanics, and in particular to a test device and method for measuring muscle or soft tissue hardness. Background technique [0002] Swelling is the increase in volume of tissues such as muscles, skin or mucous membranes due to inflammation or congestion. When lesions (such as inflammation, tumor, etc.) occur in human muscles and soft tissues, their mechanical properties (hardness, elasticity, etc.) will change significantly. [0003] In related technologies, clinical doctors can perceive the degree of illness or recovery of the patient by touching and pressing the patient's part. However, this method relies heavily on the doctor's experience, and the judgment of the patient's swelling degree is too subjective, and there is no unified classification and quantification standard for the swelling degree, which leads to the occurrence of different diag...
