- the instrument includes central unit, main memory connected to the central unit by system bus, data register, one or more adapters and analogue gauging unit.
- This gauging unit contains measuring sensor, amplifier connected to a sensor output by means of low-passageway filter, eventually a comparator connected to its output.
- the amplifier output is connected via A/D transducer to an inner system bus.
- at least another one two-way coupler is available as an adapter connected to a screen by an audiofrequency circuit.
- European patent No. EP 1161921 a uterine contractions detector and a development analyzer of contractions frequency are described. This method and instrument determines uterine contractions' frequency, analyses frequency data and generates graphical representation or set frequency in real time.
- the invention uses generally known methods of uterine activity detection. Uterine activity data are analyzed in order to specify the occurrence and frequency of contractions. Specified frequency of multiple time periods is displayed on mother/fetal screen in real time.
- a physiological events detector especially detector for uterine contractions.
- This method and instrument serves to physiological signal detection and for provision of event indication, which is related to the signal.
- the instrument includes input terminal, which is connected to the patient in order to obtain physiological signal, which shows at least one physiological event.
- the instrument also includes analytical module equipped with processor and software for control to set the occurrence of the event and to generate signal of its occurrence; and an indicator, which receives this signal and provides event indication in relationship to the signal.
- the method involves physiological signal obtaining, determining the origin of physiological event and signal generating in relationship to origination of this event.
- the aim of the invention is to create a complex system for effective risk of preterm birth prevention.
- the complex system is formed by the method of uterine activity observation based on the analysis of uterine contractions, which is designed to preterm birth prevention, together with the arrangement for performing the above mentioned method.
- the advantage is, in contrast to existing solutions, that the complex system, in agreement with invention, enables observation of the uterine activity virtually consecutively. It is also capable of running changes of patient's position and their dynamics monitoring, which can influence contractions abundance, their frequency, length and intensity. Obtained results are analyzed by the special application software and integrated with other important. information about patient and course of her gravidity at the same time to be displayed in explanatory print on the computer screen.
- Indispensable advantage of the technique is a possibility of information integration from four available information sources (see further), analyze them together and then provide specialist - gynaecologist with an efficient complex tool for recognizing the risk of preterm birth as the best and the simplest way as possible.
- Concrete realization of method of recognizing the risk of preterm birth consisting in observing the uterine activity based on the analysis of uterine contractions consists in creation of a new system of observing the uterine activity consisting of two integral components.
- the mobile autonomous "holter” type instrument is designed for continuous non-invasive scanning and recording of uterine activity in the context of movement activity of the patient (potential mother), including accessories for re-charging and data transfer to user (specialist).
- the second one, the special analytical computer programme running on regular computer of the specialist enables consecutive uterine contractions detection and determines their frequency and intensity.
- the essence of arrangement for performing the method of recognizing the risk of preterm birth consisting in observing the uterine activity in home background consists in the fact that the mobile sensor module, which saves measured data to the internal memory, is joinable via the home station's connector, which can be connected to data storage on FTP server by the wireless communication GPRS modem, whereas the data storage is accessible from the specialist's computer via Internet.
- the reason for FTP server usage is a permanent available connectivity, which can be promptly used both by home station and specialist's computer.
- a mobile sensor module as a part of microprocessor, which is connected by double-ended buses to power supply unit, connector for connection to the home station, whereas a microprocessor bus is connected to the strain gauge, accelerometer, audible or LED alarm unit (indicating the state of mobile sensor module), and a marker button, which enables indication of subjective ⁇ events (e.g. subjective contractions) by patient; all connected to the microprocessor bus-by double-ended buses.
- the home ' station is formed by microprocessor connected by double-ended buses to power supply unit, connector for mobile sensor module connection, wireless communication modem, USB module, FLASH memory unit and audible or LED alarm unit.
- the advantage of this arrangement is the fact that the specialist is enabled to practically continuous monitoring of patients with indicated risk pregnancy. As soon as the common periodical investigation shows potential problem the specialist allots a mobile instrument to the patient and starts continuous distant monitoring. But it is not a real time t monitoring - this is not necessary in this preventive phase - by default, once a day data download from the patient's instrument to the specialist's one is supposed. In case of need, the specialist can, indeed, require data update repeatedly during the day.
- the specialist has a special computer application programme (software), which processes and evaluates obtained data by the filtration and measured data analysis algorithms and enables visual graphical and numerical interpretation of obtained data and highlighting the potential risk factors.
- the invention has these benefits:
- the effect expected is oqtn financial savings in health service in the area of prenatal and subsequent care, and a significant ethical contribution to the area of mother and children care and also ; an increase in health care of citizens.
- fig. 1 shows the engagement of mobile sensor module (MSM)
- fig. 2 represents the participation of home station module (DSM)
- fig. 3 describes the engaging of home system with linkage to the central workplace

- fig. 5 depicts the application software
- fig. 6 and 6b explains the algorithm for contraction detection.
- the method of recognizing 'the risk of preterm birth consisting in observing the uterine activity based on the analysis of uterine contraction is related to the statistical proven connection (92%) between the uterine activity data and the risk of preterm birth, whereby offers a possibility of decrease of these cases.
- the basis of this method is a 'continuous monitoring of patient's uterine activity in context to her movement activity, where obtained data are measured and stored in mobile sensor module 1 at the same time and then compared and evaluated by the application software 5, which uses filtration and measured data analysis algorithms. Determining is the method of objective observation of the state of the cervix enabling consequent uterine contractions detection, determining their frequency and intensity, evaluating their causes and severity levels and, as a result, recognizing the risk of preterm birth.
- cervix score monitoring of partial factors of pathological changes on cervix.
- penal points 0-1-2 are given to five quantitative characters of trfe * cervix: o length, o permeability, o consistency, o placing in relation to .axis of small pelvis, o entering of pressing part of child.
- Application software 5 for implementation execution processes, evaluates and interprets obtained data by algorithms 57 for filtration and measured data analysis.
- Data collection is proceeded from Other' information resources, mainly from the work form "Day view” 56, which shows 1 to tfte user (specialist) necessary information for early tendency of imminent preterm birth?.
- Necessary supporting data can be entered by other work forms (52 to 55), while the form “List of patients” 51_ is the initial for patient's choice and for handling with other forms.
- Patient's file 52 contains basic data about patient (statistical in term of one gravidity), including the anamnesis.
- Form "Investigation file” 53 collects data during the gravidity, which are potentially variable with a distinction into five categories: “Status praesens” (current state of the patient), “Midwifery findings',' (cervix score, ultrasonic cervicometry), “Serial diseases”, “Pharmaceuticals” and “Laboratory investigations”.
- Form "Gravidity calendar" 54 is actually "plan" of entire gravidity course by weeks in the form of synoptic table with the possibility to complement weekly commentaries.
- Form "Gravidity file” 55 summarizes the most important data about each patient's gravidity. ;•. ' .
- Application software 5 is "the fundamental part of the invention by the view of specialist.
- a work form (window) 56 “Day view” (see further) is used, which can be accessed directly from the patients' list.
- Day v view an evolution of important value criteria, i.e. frequency of objective contractions ; with distinction by relevancy and movement dynamic of the patient in conjunction with subjective contractions (according to the patient) and then with the cervix-score value.
- Each line represents one day of monitoring, where first line above responds with current (last) day of monitoring.
- a graphical visualisation of a day's contractions history is visible in the context of changes in patient's position with the possibility of detailed look in required parts of history (function "zoom").
- Zoom function can be cancelled by clicking on the icon termination (x), which refreshes overall course in the bottom partpf ,the window. If we want to leave only the detailed preview in the lower part of the window, just click on the icon enlargement (D). Together with the function "zoom", changes of both scales are available as well as shifts, inserting and cancellation of markers, eventually a possibility to adjust curves (artefacts eliminations, etc.)
- the advantage of this lay-out is a plasticity of what the user (specialist) see - day by day - development trends of contractions in relation to cervix-score value.
- the plasticity is reached by a combination of numerical and graphical expression of all of the important criteria.
- contractions from first group have major importance. This fundamental distinction is enabled by usage of accelerometer in mobile sensor which enables registering of patient's position changes and allocates them to the contractions curve: '
