Abstract

The thigh adhesion quantitative measurement system is a sensor system for precisely locating fibers and/or bands of connective tissue formed between layers of body tissue, binding the layers together and not permitting them to glide over each other. This bonding is called an adhesion. The present system is designed to determine quantitatively the degree of adhesion and the location of high-pressure adhesion(s) such that medical removal procedures (e.g., liposuction) can be precisely performed. The system makes use of a scanning device having an array of pressure sensors, the scanning device being defined by a flexible plate wrapped by a belt to a patient'"'"'s limb, such as a thigh. A flexible cable connects the plate to a body-worn transmitter that wirelessly transmits real-time pressure distribution images received from the flexible plate to a computer for use by doctors preparing for the liposuction procedure.

Claims

1. A thigh adhesion quantitative measurement system, comprising:

a processor;

a scanning device, the scanning device consisting of a flexible plate and a flexible plate pressure sensor array disposed thereon and in operable communication with the processor, the flexible plate pressure sensor array having a central active sensor area and two inactive areas disposed on opposing ends of the central active sensor area, a (0,0) datum coordinate marker disposed on a corner of an active portion of the central active sensor area, the scanning device conforming to and taking pressure readings of the inner thigh region of a subject'"'"'s body, sensor belts extending from opposite edges of the scanning device to secure the scanning device to the subject'"'"'s inner thigh region;

means for digitizing the pressure readings taken by the scanning device to obtain a pressure profile providing indicia of high pressure points within the region;

a wireless data converter in operable communication with the processor; and

a pressure scanning display computer in communication with the wireless data converter, the pressure scanning display computer having a screen for displaying the pressure profile as images, wherein the pressure profile images are presented as a color map of pressure over the subject'"'"'s inner thigh region.

2. The thigh adhesion quantitative measurement system according to claim 1, further comprising a multiplexer connected between the scanning device and the processor, the multiplexer selecting inputs to scan elements of the pressure sensor continuously into the processor.

3. The thigh adhesion quantitative measurement system according to claim 2, wherein the processor further comprises a signal conditioner circuit for conditioning the pressure data before the data is digitized.

4. The thigh adhesion quantitative measurement system according to claim 3, wherein the signal conditioner circuit is selected from the group consisting of a programmable gain amplifier circuit and a low pass filter circuit.

5. The thigh adhesion quantitative measurement system according to claim 3, further comprising a DC offset compensator connected to the signal conditioner circuit.

6. The thigh adhesion quantitative measurement system according to claim 1, further comprising a connection cable extending from the flexible plate and attachable to the processor, the connection cable facilitating operable communication of the scanning device with the processor.

7. The thigh adhesion quantitative measurement system according to claim 1, further comprising:

a transmitter unit belt; and

a transmitter unit belt loop disposed on a housing of the wireless data converter, the transmitter unit belt being threaded through the transmitter unit belt loop to secure the wireless data converter to the subject'"'"'s body.
