Is there any daily/weekly service (if it's a vending machine)? Such questions interest me in advance
do you mean a sort of subscription plan?
No,
I meant maintenance, as in coffee vending machines (for example)
Well, this is something we are going to discuss with local distributors
I rephrase my question: does the owner of your machine need to add anything to the device (something to fill) every day or every week? (For example, in a coffee machine you need to add coffee, glasses)
No for device are required only electricity
look
Health Monitor specification details.
The device allows to keep track of low acetone admixtures in patient’s exhaled air. It is comprised of power supply source, spectrometer, discharge cell, sample selection line and process unit.
Health monitor is an electrical accessory, which is to be used with 12V direct current nominal voltage (inclusive). In case of instrument’s failure, voltage (on condition the circuit is broken), multiplied by measured current (which is meant to flow through the circuit with the possible defect) is not more than 15 volt-ampere.
The monitor is constructed of non-toxic materials, sans the ionization radiation. The device is isolated with no impact on the environment, as well as on the vital activity of any organism.
Once an exhaled air sample is drawn, it goes straight to the sample selection line, where the discharge is to be initialized in the discharge cell. Process unit stands for the registration of an exhaled air emission spectrum, with the subsequent analysis of it. Upon that, in order to decrease the exhaled air pressure in a discharge cell, a purge pump is used. Discharge initialization is conducted with the low pressure. Analysis of an exhaled air emission spectrum is to be done by means of spectrum intensity normalization, (rationing with the water vapor concentration in an exhaled air). Hence, water vapors have no impact on the measuring accuracy.
To conduct measurements, blowing the monitor’s tube for a few seconds is enough. All the following processing is automatically accomplished.
The main work principles of the device:
1. An exhaled air sample is drawn, and carried to the sample selection line.
2. With help of adjustable valve, the exhaled airflow through the sample selection line is easily regulated.
3. The air is passed to the discharge cell, with low air pressure (10 – 100 torr), kept up by the purge pump.
4. On condition the process pressure is reached, a glow discharge is initialized in the discharge cell (with constant current, varying from 5 to 20 mA). To maintain the glow discharge, a 1500V and Imax = 20 mA power supply is applied.
5. Further, discharge’s emission radiation is passed to the spectrometer through the fiber-optic cable. Spectrometer’s signal is registered and processed by the processing unit.
6. The device’s software analyses the exhaled air specter and compares it to the surrounding air specter. Based on this comparison, various impurity gases concentrations are calculated.
The device could be used for measuring the blood sugar level, as well as to detect the infancy of lung carcinoma, stomach ulcer and diabetes. It experimentally finds, the acetone concentration, measure by Health Monitor, is linearly proportional to the blood sugar level. Presence of the certain impurity gases does well indicate a probable disease, even though the device does not find the precise diagnosis. Such a medical test results may accent the necessity of the full medical examination.
Moreover, technical facility, described above, could serve as a detector of pollution and impurity gases in an environment air, such as mercury, xenon, methane vapors, narcotic and explosive substances in the air, etc.
