Description

Portable device for personal diagnosis of erectile dysfunction symptoms. The present invention relates to medical technology, namely, devices used in urology and andrology.

The present invention is intended to perform the test of nocturnal penile tumescence and rigidity in the treatment of psychogenic erectile dysfunction.

Known device Rigi-Scan (Rigi-Scan) for determining the radial rigidity and tumescence of the penis in the form of a portable portable meter, which is bandaged to the patient's thigh. (US patent No. 4515166, class A61B 5/20, 1985).

The meter consists of two loop ends, one of which is placed at the root of the penis, and the second at the top, recording elements in the form of linear displacement sensors (cables inside a cloth cover), and an additional data conversion unit.

When measuring tumescence, the loops are tightened around the circumference every 30 seconds with a force of 1.7 N, and the circumference of the penis (loop length) is measured.

Re-measurement is made after 15 s without actively tightening the loop.

If tumescence results in an increase in circumference of 10 mm or more from the baseline, initiate the rigidity measurement.

The rigidity is measured every 30 seconds by compressing the hinges with a force of 2.8 N and is evaluated as a percentage, with the rigidity of the incompressible rubber rod being taken as 100%.

With a decrease in tumescence to 100 mm from the baseline, the measurement of rigidity is stopped until the next episode of adequate tumescence. Rigi-Scan allows three continuous 10-hour sessions.

The data can then be downloaded to a computer and processed, reproduced and printed using special software.

The disadvantages of the known device are:

- inconvenience of use due to rather large weight and size parameters (100 × 150 × 50 mm, weight over 200 g);

- the impossibility of determining the time of the onset of an erection, its duration, frequency and quantitative assessment, which leads to difficulties in making a diagnosis;

- communication with a personal computer only through an additional data conversion unit.

Known portable device for personal diagnosis of symptoms of erectile dysfunction, containing fixed on the patient's body, a portable module for recording the state of erection, configured to transmit data to a personal computer and connected to pressure sensors for measuring erection in the form of pneumatic silicone rings located at the base and on the head of the genital member, and containing an information carrier, analog stages of amplification and filtering of the signal coming from pressure sensors, a microcontroller for converting data and recording them on a medium, a power manager, a battery and a charger (PM patent No. 135509, class A61B 5/00, 2013 g.).

Moreover, the pressure sensors are connected to the portable module on one side by means of a flexible silicone hose soldered into the pressure sensor, and on the other - using a pneumatic connector.

The portable module is connected to a personal computer via a USB cable or wirelessly. The disadvantages of this design are: inconvenience for the patient due to the need to wear the module on the belt around the clock;

- the complexity of the design due to the presence of tubes running from the module to the sensors;

- the complexity of converting the pressure in the tubes into a volume value, since calibration required.

Closest to the proposed invention is a portable device for personal diagnosis of symptoms of erectile dysfunction, containing a portable module wearable with a processor, an inductance sensor connected to it for diagnosing erectile dysfunction, in the form of a curvilinear element with two peripheral ends, and a reader. (Patent PM No. 137715, class A61F 5/41, 2014).

The known device is connected to a personal computer (PC) with a cable for reading and processing information from a portable portable module.

The disadvantages of the known design are:

- inconvenient use of the system due to the size and weight of the wearable portable module;

- the design of the inductance sensor for the diagnosis of erectile dysfunction, its attachment to the patient and the connection by means of wires with the wearable portable module create discomfort for the patient;

- to read information from the module, it is necessary to connect it to a PC by wire and download special software (software), which leads to the need for an additional connector on the module and an additional increase in its overall dimensions;

- the need for periodic charging of the accumulators built into the block.

The technical result solved by the present invention is the creation of a portable device for personal diagnosis of symptoms of erectile dysfunction, which allows to increase the accuracy and reliability of measurements with repeated use of a portable portable module.

The technical result in the present invention is achieved by creating a portable device for personal diagnosis of symptoms of erectile dysfunction, containing a wearable portable module with a processor, an inductive pressure sensor connected to it and a reader, in which, according to the invention, the reader is made in the form of a stationary portable module consisting of a microprocessor with a USB controller, a built-in radio transmitter and a quartz resonator providing synchronization of data exchange with a portable portable module via a radio channel, and the portable portable module additionally contains a memory card, a power supply, 2 counters-timers connected to a microprocessor generator for measuring the inductance of a pressure measurement sensor, watchdog counter-timer connected to a low frequency generator, waking up the microprocessor to measure the inductance value of the pressure measurement sensor and recording the measurement results into a memory card these, an indicator that is triggered when the memory card is overflowed and in the absence of contact with the inductive sensor, a reed switch for switching the operating mode of the portable portable module and a radio transmitter, both modules are connected to each other by a radio channel, a quartz crystal is connected to the terminals of the portable portable generator module built into the microprocessor resonator, and in the measurement mode an inductive sensor.

In the proposed invention, the wearable portable module is made in a miniature design due to its implementation on the basis of a "system on a chip" (SOIC) containing a microcontroller, FLASH memory for data storage and a radio transmitter.

The proposed design does not create discomfort when measuring nocturnal penile tumescence and rigidity due to a miniature portable portable module with a power supply (battery) placed on the patient's body together with an inductance sensor.

The proposed portable device for personal diagnostics of symptoms of erectile dysfunction through the use of a reader made in the form of a stationary portable module with its radio receiver allows you to receive and transmit data from several different wearable portable modules of patients.

The essence of the proposed portable device for personal diagnosis of symptoms of erectile dysfunction is illustrated by the following description and drawings, where:

in fig. 1 shows a diagram of the proposed device for personal diagnosis of symptoms of erectile dysfunction;

in fig. 2 shows a diagram of a wearable portable module.

A portable device for personal diagnosis of symptoms of erectile dysfunction consists of a wearable portable and stationary portable modules.

The reader is made in the form of a stationary portable module consisting of a microprocessor 1 with a USB controller 2, a built-in radio transmitter 3 and a quartz resonator 4 (not shown in the devil), which provides synchronization of data exchange with a portable portable module via a radio channel.

The wearable portable module consists of an inductive pressure measurement sensor 5, a microprocessor 6, a card 7, a power supply 8, a time counter consisting of two counters 9 and 10, connected to a microprocessor generator 11 to measure the inductance of a pressure measurement sensor 5, a watchdog timer 12, connected to a low frequency generator 13, waking up the microprocessor to measure the inductance value of the pressure measurement sensor and recording the measurement results into the memory card 7, indicator 14, which is triggered when the memory card 7 is full and in the absence of contact with the inductive sensor 5, reed switch 15 for switching the mode of operation of the portable portable module and the radio transmitter 16. Moreover, both modules are connected to each other by a radio channel, while a quartz resonator 4 is connected to the terminals 17 and 18 of the generator 11 built into the microprocessor in the portable portable module in the read mode, and the inductive sensor 5 is connected in the measurement mode.

A portable device for personal diagnosis of erectile dysfunction symptoms works as follows:

The wearable portable module operates in three modes:

1. Measurement mode;

2. Save and shutdown mode (sleep mode);

3. Mode of data exchange with a stationary portable module via radio channel.

In the measurement mode, the inductive pressure measurement sensor 5 is connected via inputs 17 and 18 to the built-in generator 11 of the microprocessor 6 of the wearable portable module.

After switching on the module, the generator AND is started at its average operating frequency, the change in which becomes inversely proportional to the value of the inductance of the sensor 5.

When the geometric dimensions of the inductive sensor 5 change, its inductance and, accordingly, the clock frequency of the generator 11 of the microprocessor 6 of the wearable portable module change.

The time counter consists of two timer counters 9 and 10.

Using the built-in timer-counter 9, a certain number of clock cycles of the generator 11 are counted for a fixed time interval T, determined by the value of the inductance of the sensor 5.

The fixed segment T is counted by a counter-timer 10, which operates from a generator at a low frequency 13 and does not depend on the value of the inductance of the external sensor.

The value of T is programmatically selected so that the number of counted pulses of the generator 11 is sufficient to measure the change in the inductance of the sensor 5 with the required accuracy.

The main operating time of the microprocessor is in the so-called sleep mode (sleep mode).

The current consumption of the portable portable module from the built-in power supply 8 at this time is negligible (units of microamperes), which makes it possible to use a small-sized battery as a power source for the microprocessor without a power switch for the entire operation time of the portable portable module.

The inclusion (awakening) of the microprocessor of the portable portable module is carried out using a reed switch 15 built into it, when the recorder is brought to an external magnet.

To periodically turn on the wearable portable module, measure the inductance value and store it in the memory card 7, it periodically wakes from sleep mode using the built-in watchdog counter-timer 12, which is also connected to the low frequency generator 13 and is programmed for a certain interval of waking up the microprocessor (from units up to tens of seconds).

Upon waking up, the microprocessor 6 performs a single measurement of the inductance value described above, records the measurement results in its internal non-volatile memory card 7 and is turned off until its next wake-up by the watchdog timer 12.

At the end of the measurements, the inductive pressure measurement sensor 5 is disconnected from the wearable portable module, which automatically detects that the sensor is disconnected and goes into sleep mode until the next wake-up for additional measurements or data reading.

Data in memory is stored as double-byte words. The memory capacity of the MP (14 Kbytes) and the recording frequency into it (1 time in 10 sec) is sufficient to monitor the change in the inductance value of sensor 1 for 18 hours.

When the memory card 7 is full, the wearable portable module stops writing data to it and, using the indicator 14, signals this by flashing, and then goes into sleep mode.

If there is no contact with the inductive sensor 5, the wearable portable module signals this by triple blinking of the indicator 14 and falling asleep.

Such a mode of alternating sleep and short-term wake-up or shutdown in the absence of free memory or the absence of a sensor 5 allows for a long time to maintain the performance of the wearable portable module from the built-in small capacity battery,

The mode of reading data from a wearable portable module is performed using a radio transmitter 3 built into the microprocessor.

To start the data reading mode, it is necessary to connect a quartz resonator 4 instead of an inductive pressure sensor 5 to terminals 17 and 18 of the generator 11 of the microprocessor.

The quartz resonator 4 is necessary to stabilize the frequency of the oscillator 11, which is used in this case to transmit data from the portable module to a stationary radio channel, which may have, for example, a strip antenna,

Thereafter, the wearable portable unit is brought to the stationary portable unit of the connected personal computer PC.

The reed switch 15 built into the wearable portable module is triggered by a magnet located in the stationary portable module and starts the wearable portable module in data transfer mode.

The microprocessor 6 of the wearable portable module determines the start mode of its generator 11 as generation from the quartz resonator 4 and starts the program for transmitting data to the stationary portable module via a radio channel (not shown in the drawing).

The reader transmits data to a PC via a USB channel to reflect the data, using specialized software, in the form of a graph on the screen and save them in the PC memory for further work.

After transferring all the contents of its internal memory, the wearable portable module goes into sleep mode until the next restart by the reed switch.

The software (registered certificate number No. 20016611845 of 12/17/2015) on a PC allows you to save the data received from the wearable portable module, display them in the form of graphs, change the scale of the curves and save them for further viewing in the database.
