The present invention relates generally to a sensor assembly for self-diagnosis of breast cancer. Particularly, the present invention relates to a sensor assembly which is attached to a skin around user's breast to self-diagnose breast cancer, wherein the sensor assembly includes a poly-di-methyl-siloxane (PDMS) module and a mounting module to which the PDMS module is detachably mounted in a screw-coupling manner in which the mounting module wirelessly supplies an operating power to the PDMS module through contact between electrodes.
Generally, breast cancer is cancer that occurs mainly in women in their 40s and needs early diagnosis and treatment in order to reduce the death rate. However, in the early of the occurrence of the breast cancer, most of patients do not feel subjective symptoms, but often find a pain-free lump through a tactile self-examination. Results of such tactile self-examinations may differ according to patients self diagnostic proficiency and sensitivity, so a regular medical checkup is recommended.
A breast cancer-imaging apparatus includes an X-ray mammographic apparatus, an ultrasonic scanner, a magnetic resonance imaging (MRI) apparatus, etc., among which the X-ray mammographic apparatus (disclosed in Korean Patent Application Nos. 10-2009-0096934 and 10-2008-0004564) is widely used in a regular medical checkup for early diagnosis of breast cancer. The X-ray mammographic apparatus uses a phenomenon that X-ray transmissivity differs according to breast tissue, so as to find breast tissue absorbing X-rays, particularly, a calcified tissue, for example. The calcified tissue is likely to develop into cancer tissue, so early fining of the calcified tissue also helps preventing breast cancer.
However, since the X-ray mammographic apparatus tends to find breast cancer tissue by a visual inspection of abnormal breast tissue which is less distinguishable from normal breast tissue, diagnosis by a cancer specialist is essentially required. Thus, the X-ray mammographic apparatus has problems in that the diagnostic precision differs according to the specialists proficiency, and inspection costs are expensive. In addition, there are other problems such as restrictive 2D monitoring using electromagnetic radiation having a wavelength of less than that of violet rays, the risk of radiation exposure, and the like. Particularly, as the incidence of breast cancer increases with westernized eating habits, it is required to overcome the problems with the conventional X-ray mammographic apparatus and to develop a digitized self diagnostic system for breast cancer.
The foregoing is intended merely to aid in the understanding of the background of the present invention, and is not intended to mean that the present invention falls within the purview of the related art that is already known to those skilled in the art.
Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and an object of the present invention is to propose a sensor assembly for self-diagnosis of breast cancer, wherein the sensor assembly is attached to a skin around user's breast to self-diagnose breast cancer, wherein the sensor assembly includes a poly-di-methyl-siloxane (PDMS) module and a mounting module to which the PDMS module is detachably mounted in a screw-coupling manner in which the mounting module wirelessly supplies an operating power to the PDMS module through contact between electrodes.
Another object of the present invention is to provide a sensor assembly for self-diagnosis of breast cancer, wherein the sensor assembly includes a poly-di-methyl-siloxane (PDMS) module and a mounting module to which the PDMS module is detachably mounted in a screw-coupling manner in which the mounting module wirelessly supplies an operating power to the PDMS module through contact between electrodes, thereby having the effects that the sensor assembly can be easily used, and when in not use, simple screw-detachment of the PDMS module from the mounting module enables the PDMS module to be turned off to save power.

The PDMS module 100 is a sensor module which senses elasticity distribution of breast tissue and emits near-infrared rays to allow a mobile analyzing device to obtain and process tactile images and near-infrared images for self-diagnosis of breast cancer. As illustrated in
The casing 110 has a tactile sensor 111 mounted in a rectangular recess 112 of the casing, a plurality of first LED holders 113 respectively provided in four inner walls of the rectangular recess 112, and a screw part 114 provided on a lower side of the casing 110 so as to be screw-coupled with the mounting module 200 to be described later.
The LED holder frame 120 is fixedly inserted into the casing 110 and has a plurality of second LED holders 121 corresponding to the first LED holders 113.
The LED-mounting frame 130 is fixedly inserted into the casing 110 to which the LED holder frame 120 has been mounted, and has four LED brackets 132 to which four near-infrared LEDs 131 are respectively mounted to emit near-infrared rays towards breast tissue so as to obtain near-infrared images of the breast tissue, a power connecting PCB plate 133 to which the four LED brackets are mounted, and a fixing protrusion 134 provided on a lower side of the power connecting PCB plate 133.
The first LED holders 113 and the second LED holders 121 serve to maintain a direction of near-infrared rays emitted from the near-infrared LEDs 131 without scattering and leaking of the near-infrared rays. That is, the first LED holders 113 and the second LED holders serve as passages to allow the near-infrared rays to be guided towards the tactile sensor 111.
The first LED holder 113 and the second LED holder 121 vertically join together to form an LED-mounting hole through which the near-infrared LED 131 mounted to the LED bracket 132 is fixedly held without additional components. The four near-infrared LEDs 131 are fixedly mounted at 90 degree angles to the LED brackets 132, so that the four near-infrared LEDs can emit near-infrared rays towards the tactile sensor 111 of the PDMS module 100 at the same height and direction.

Here, the contact electrodes may be disconnected from the power source of the mounting module when the PDMS module is unscrewed from the mounting module. Although the sensor assembly of the present invention has a separate power ON/OFF switch (not shown), when the PDMS module 100 is unscrewed from the mounting module, the power is turned off so as to save the battery power.
The fixing protrusion 134 of the LED-mounting frame 130 serves to allow the connection between contact electrodes between the PDMS module and the mounting module at the coupling-stop position when the PDMS module is screw-coupled to the mounting module.
The mounting module 200 is a module for attaching a mobile analyzing device. The mounting module 200 can be detachably coupled with the PDMS module 100 in a screw-coupling manner in which the mounting module can wirelessly supply an operating power to the PDMS module through contact between electrodes. As illustrated in
The mounting module 200 additionally includes a clip-type device holder 240 fastened to one side of the base frame 230 to hold a mobile analyzing device. The device holder 240 may have a holding plate, a connection part 141 provided on one side of the holding plate so as to be fastened to one side of the base frame 230, a connection pin 242 connecting the connection part 241 and the connecting side of the base frame 230, a spring member 243 coupled around the connection pin 242 to provide a coupling force to resiliently grip the mobile analyzing device, and a support part 244 provided on the other side of the holding plate to support the mobile analyzing device. Here, the mobile analyzing device to be held by the device holder 240 is a mobile terminal which has a camera unit for picking up tactile images and near-infrared images, and a program engine (application) for processing combined images of the tactile images and the near-infrared images to self-diagnose breast cancer.
