Title: Developing 'JAHAGIBA' and its prerequisite test; wireless measuring equipment of erectile dysfunction (replacing 'RIGISCAN')
Summary:
Most urology hospitals take usage of 'RIGISCAN' for measuring erectile dysfunction. The testers cannot help using it for Industrial Accident Insurance to cover any Industrial accident especially pelvis injury, which causes erectile dysfunction. However, the patients while being tested have the following inconvenience. The patients have to wear it while sleeping. Any slight move of the patients can cause failure of the test. Therefore, they can have another problem, somnipathy, if the test acting in a long term. 'JAHAKIBA', wireless measuring equipment of erectile dysfunction will solve the problem. It will reduce the error, which is happened by movement and compensate the inconvenience.
Introduction:
Sexual disorders, such as erectile dysfunction is mostly caused by blood circulation disorders.
Heart disorder would be suspected for erectile dysfunction. So to solve the erectile dysfunction problem are reviewed blood circulation and heart systems. Erectile dysfunction is divided into organic erectile dysfunction, whose reason is nerve, blood vessel or hormone disorders and psychological erectile dysfunction, which is caused by psychological problem or pressure. Psychological erectile dysfunction is caused by stress, discomfort, depression while organic erectile dysfunction is caused by mostly aging and heart disease like high blood pressure, diabetes, etc. 50 percentage of erectile dysfunction is organic ones and it is getting higher as human kinds aging. Its test methods are blood male sex hormone test, stress test, **bleep** analysis (analyzes the health and viability of a man's sperm), Rigiscan, etc. Most urology take usage of 'RIGISCAN' for measuring erectile dysfunction. RIGISCAN is the erectile test, a patient wears a equipment in the **bleep** during sleeping in the night for about 7 hours. The equipment measures erectile frequency, diameters, etc. The testers take a usage of this test for Industrial Accident Insurance to cover any Industrial accident especially pelvis injury, which causes erectile dysfunction. However, the patients while being tested have the following inconvenience.
The patients must wear it while sleeping. Any slight movement of the patients can cause failure of the test. Therefore, they can have another problem, somnipathy, if the test acting in a long term. The strap around **bleep** is often took off and the test cannot be reliable. The test would be continued in a long term. Normally none of any single erectile phenomenon must be observed to be covered by Industrial Accident Insurance in straight three days. The patients should stay in the test center and it costs them a good amount of admission fee. The tests also should take a good amount of time to have any reliable test result. Therefore, any new method with easiness and sensibility is needed for measurement reliability. Today researches through biological signals such as electromyography, electroencephalography to detect human intension are getting popular as biodynamics and medical and biological engineering being advanced. Electromyograph detects the electric potential generated by muscle cells and evaluates the intension of the power and activity, which human being makes. Using the technologies with wireless equipment will remove the discomfort and unreliability from the patients and testers.
Experimental Procedure:
We designed a conditional probability experiment as using air pump for prerequisite experiment for developing 'JAHAKIBA.‘
Illustration 1
Conditional probability experiment (Illustration 1):
We put a flex sensor on the surface of long balloon. As on and off an air pump, which produces air into a balloon, we measure the voltage value from the flex sensor, which would be transformed as the balloon's size is getting bigger and smaller for a certain period and record the changes. The changing records will be shown on a computer monitor. In this experiment, an air pump and two solenoid valves will be used for controlling air in the balloon. In this experiment, we adopted an air pressure sensor and a glass tank instead of the balloon. We made an algorithm to calculate the pressure changing value into psi and kPa.
Experiment method:
Air pump controlling (with the components of Figure 1, 2, 3):
Figure 1 Air pump DAP-3657
Figure 2 Solenoid Valve VK-332-5GS
Figure 3 MyRIO
MyRIO's 5 voltage output signal has triggered to turn on a mechanical type relay and 24 voltage from outsource is released to run the air pump. When the air pump is on, a valve is opened to let the air come in the tank. When the air pump is off, a valve is closed and another valve is opened to let the air go out of the tank. There are two ways of controlling, manual and automatic, for which the user has to set up the highest and lowest range and the air pump only operates in the range. The air transfers through air hoses into the glass tank.
Data measuring and collecting (with Figure 4 and LabVIEW):
Figure 4 Pressure sensor 33A-015I-2210
The air in the glass tank is transferred through an air hose to the pressure sensor and it measures the pressure. The pressure sensor measures in the format of voltage is transformed into psi and kPa value by the given voltage to psi and kPa transforming formula in its manual.

Test results:
Manual controlling test results:
Manual controlling is to see if each pump, valve, etc. works fine. As turning on and off the vertical toggle switch of the manual mode, we check out the pump valves, etc. MyRIO reads the voltage from the pressure sensor and LabVIEW shows them in voltage, psi and kPa.
Automatic controlling test results:
At the automatic controlling mode, the tester sets up the maximal number and minimal number of the pressure voltage value and the air pump runs between them. The measured voltage number is transformed in psi, kPa values with the following formula. The measured valves run between the maximal setting number and minimal number.
The Conclusion:
Sexual disorders, such as erectile dysfunction is mostly caused by blood circulation disorders. Heart disorder would be suspected for erectile dysfunction. Most urology hospitals take usage of 'RIGISCAN' for measuring erectile dysfunction. However, the patients while being tested have the following inconvenience. The patients must wear it while sleeping. Any slight move of the patients can cause failure of the test. Therefore, they can have another problem, somnipathy, if the test acting in a long term. The strap around **bleep** is often took off and the test cannot be reliable. The test would be continued in a long term. We developed 'JAHAGIBA'; wireless measuring equipment of erectile dysfunction for replacing 'RIGISCAN' and did its prerequisite test by air pressure controlling. Like the following image, we planned to measure the voltage value around the balloon with a flex sensor. However, we replaced it with the air pressure testing because of the technical issue of the sensor. The test has two modes, manual and automatic ones. The air pump works with two valves and the pressure sensor measures the air pressure in the tank in voltage value. The voltage values are transformed into any values in the unit of Psi and kPa with a certain formula or algorithm. By the test, we could measure the pressure change in a certain period. We still have two missions. One is wireless controlling and two is adopting flex sensor or others. The wireless controlling is supposed to control the measuring system as good as the current wired system. When we succeed in wireless controlling and adopting new sensors, we should test them with a long balloon. After that any clinical trials is supposed to be done to see if there is any discomfort and inconvenience in the test term.
The advantage of wireless controlling function would compensate of the discomfort, which is caused by wearing the measuring device, like Rigiscan. The 'JAHAKIBA' would be able to be used in any medical and clinical or industrial fields for measuring muscle expansion, etc., too. As doing this test, we learned how to make any factor, such as moisture, temperature, etc. stay in a certain range. This know-how can be adopted in any things of internet, such as smart planting, etc.
