Abstract
Description
Technical Field
[0001] The present invention relates to performing actions or making judgments such as scratching, applying medicine, or consulting a doctor while viewing the conditions of the back, head, neck, and buttocks that cannot be confirmed by oneself in real time with a camera.
Background Art
[0002] The hands of grandchildren or the rods for applying medicine were convenient for scratching or applying medicine to areas that could not be reached by hand for treatment.
[0003] However, one had to perform treatment without being able to grasp the conditions of the itchy areas or the skin conditions when applying medicine.
[0004] As an improvement measure, there are methods such as using a mirror or taking an overall picture with a camera from the side of the back, head, neck, and buttocks for confirmation. However, when performing treatment while using a mirror, difficulties occur where the left and right are reversed and the hands cannot move as desired. Also, for taking pictures from a distance with a camera, it takes time and effort to set up each time.

Summary of the Invention
Problems to be Solved by the Invention
[0006] The problems to be solved are that in the conventional method, one has to perform treatment without being able to grasp the conditions of one's own back, head, neck, and buttocks, cannot intuitively operate the instrument, and it takes time and effort for setting up.
Means for Solving the Problems
[0007] The most important feature of this invention is that a small camera is attached to a part of a rod. [Effects of the Invention]
[0008] This invention offers the advantage of allowing users to intuitively observe the condition of the skin on their back, back of the head, neck, and buttocks, and then scratch, apply medication to, or treat the necessary areas, and, in some cases, decide whether or not to consult a doctor. [Brief explanation of the drawing]
[0009] [Figure 1] Figure 1 shows a small camera attached to a rod.
[0010] [Figure 2] Figure 2 shows a small camera mounted above the treatment area.
[0011] [Figure 3] Figure 3 shows the rod with a stabilizing material attached to ensure stability. [Modes for carrying out the invention]
[0012] Embodiments of the present invention will be described below. [Examples]
[0013] Figure 1 shows the most useful prototype. An endoscope camera is mounted on the back, back of the head, neck, and buttocks side of a back scratcher or medicine applicator stick. This is because the stick does not obstruct the back, back of the head, neck, and buttocks, and the center of gravity is on the side of the body, making it easy to operate stably without rotation. By using an endoscope camera, a light source was secured, and the condition of the back, back of the head, neck, and buttocks could be checked in detail. However, since the skin is viewed from an oblique angle, if it is desired to view it from a vertical direction, the shape of the lens or image correction on the LCD side will be necessary. [Examples]
[0014] Enable the rod to be flexibly bent and enable the orientation to be changed without fixing the camera.
Example
[0015] As shown in Figure 2, place the lens of the camera above the treatment part to obtain an image seen from above.
Example
[0016] As shown in Figure 3, arrange a stabilizing material around the treatment part to prevent the rod from rotating.

Claims
1. A camera is attached to a pole, allowing you to view images of the back, back of the head, neck, and buttocks on an LCD screen.
2. A camera is attached to part of the back scratcher, allowing users to view and operate the device while checking the back, back of the head, neck, and buttocks using a smartphone, tablet, or PC.
3. A camera is attached to the applicator stick, allowing the user to check the condition of the affected area while applying medication. Alternatively, the user can check the condition and decide whether or not to consult a doctor.
4. Camera images can be sent to the LCD screen via USB or wirelessly.
5. The camera used will be a small one with a light source similar to that of an endoscope camera.
6. Make the rod flexible enough to be bent, and allow you to change the camera's direction.
7. On the LCD side, inverted and processed images will also be available for easier viewing.
8. The lens is deformed like a fisheye lens so that the back, back of the head, neck, and buttocks appear as if viewed from directly above.
9. By placing a mirror or similar object in front of the lens, you can capture a vertical view of your back, the back of your head, your neck, and your buttocks.
10. By placing a small camera above the treatment area, it becomes easier to see the overall condition of the skin.
11. By attaching components around the treatment area and extending to the left and right from the rod, these components come into contact with the skin around the affected area, suppressing shaking and rotation of the treatment area and camera, making operation easier.
12. By using transparent materials for the rod, treatment area, and stabilizing material, the affected area can be made as visible as possible in the camera image.
