Description

The invention relates to medical products intended for measuring the size of individual organs and body parts of adults and children, in particular, the height of the uterine fundus in pregnant women above the pubis in order to assess the quality of pregnancy and the dynamics of the size of the uterus, fetus and amniotic fluid volume.

Known soft ruler made of rubberized fabric or soft plastic 150 cm long and 1.5-2.0 cm wide with markings on both sides, applied in the form of major divisions with an interval of 1 mm, with a report of the scale indicators on each side from the opposite end , covered with a metal coating, with the ability to fold in a circle in the form of a roll, which can be squeezed and tied with a string or folded into a round plastic box with a lid (The measuring tape is the faithful assistant of a tailor, doctor and ordinary housewife.https: //www.google. com / amp / s / fb.ru / article / 147580 / santimetrovaya-lenta --- vernyiy-pomoschnik-portnogo-medika-i-obyichnoy-domohozyayki / amp / Found on the Internet on 10/21/2020).

The disadvantage of the known centimeter tape is a narrow range of application, low speed, efficiency, safety, accuracy and high labor intensity due to the lack of registration and diagnostic capabilities and public use of the tape. The fact is that the tape is only a measuring device, moreover, it is used to measure body size in many women. At the same time, the tape does not provide registration and evaluation of the obtained data, since it has insufficient width, and also lacks columns with empty and filled cells. It is no secret that due to the use of one tape in several women, the exclusion of infectious infection from each other and from third parties through this tape is not ensured.

Due to the lack of registration and diagnostic function in the known tape, an outpatient card of a pregnant woman and a normal gravidogram are currently used in this role. Moreover, this outpatient card is made of paper, therefore, it does not ensure the safety of information when it gets wet in water, milk, jam and after accidentally dousing with other liquid food products during transportation, for example, in a shopping bag. The need to use two products (tape and outpatient card) reduces efficiency, accuracy, speed and increases labor intensity. In addition, this increases the likelihood of losing the obtained data due to damage and / or loss of an outpatient card due to the fault of a pregnant woman or her family members by accident.

The absence in the known tape of the possibility of registering the obtained data and the presence of similar indicators characteristic of a normal pregnancy slows down the rate of diagnosis of the course of pregnancy and the dynamics of the fetus. The tape can only be used as a measuring device, therefore, the known tape allows an erroneous and late conclusion about the dynamics of fetal growth in a pregnant woman under study, which can lead to a late identification in a woman of the risk of fetal growth retardation, macrosomia, low and polyhydramnios, and other developmental pathologies the fetus due to late additional examination, to termination of pregnancy and to fetal death.

Known flexible tape, foldable in a roll with a double centimeter scale in the range from 0 to 150 cm on one side and in centimeters and inches in the range from 0 to 60 inches on the back for medical measurement of body measurements, made of non-stretch vinyl, from soft plastic, white, with sufficiently large and readable black markings on the bright white tape, metal tabs at each end to prevent abrasion, designed to measure any curved surface (Soft double-scale tape measure.https: //www.amazon.com / Measure-Flexible-Measurement-Centimetre-60-inch% EF% BC% 88White% EF% BC% 89 / dp / B07MT89MCW / ref = pd_bxgy_3 / 137-4857572-1378014? _Encoding = UTF8 & pd_rd_i = B07MT89_da6 & pd_ff_44 -90d6-c60410ef62c6 & pd_rd_w = 2zsTN & pd_rd_wg = 7d3wB & pf_rd_p = ce6c479b-ef53-49a6-845b-bbbf35c28dd3 & pf_rd_r = 20QSZ95SH7ZZFR9

The disadvantage of the known centimeter tape is a narrow range of application, low speed, efficiency, safety, accuracy and high labor intensity due to the use of the same tape for many women, insufficient tape width, the absence of columns with divisions and cells in it opposite whole scale values, one of which demonstrates the correspondence of the size of the standing height of the uterine fundus to the gestational age in weeks, corresponding to the normal dynamics of fetal growth and the volume of amniotic fluid during a normal pregnancy, and the second and third columns allow registering in cells opposite the scale values in one - gestation periods in weeks, in another - the date of determination of these values of the height of the uterine fundus in the studied pregnant woman.

The fact is that due to the use of the tape by many women one after another, an infectious infection of them with its help is not excluded.

In addition, due to the narrow width of the tape and the absence of columns in it, in one of which the cells are filled and demonstrate the correspondence of the height of the uterine fundus to the normal gestation period, and the cells of other columns are empty with the possibility of registering the gestational age in them in weeks and dates. conducted studies, during which the dimensions of the height of the standing of the bottom of the uterus in the studied pregnant woman are determined, it is required to have, in addition to the tape, a second product that provides registration of the dimensions of the height of the standing of the bottom of the uterus at certain periods of pregnancy in a pregnant woman and graphically demonstrates the dynamics of the studied parameters in the norm in the form of a gravidogram ... In this regard, the outpatient card of a pregnant woman is currently used for registration. This product is made of paper, which does not ensure the safety of information in case of accidental wetting in water, milk, jam and when doused with other liquid food products. The presence of two products reduces efficiency, accuracy, speed and increases labor intensity. In addition, this increases the likelihood of loss of the obtained data due to damage and / or loss of the second product due to the fault of a pregnant woman or her family members by accident.

In addition, the absence of an example of the dynamics of the height of the uterine fundus during normal pregnancy does not provide the known tape with the possibility of using it to diagnose the development of the quality of pregnancy, the dynamics of the development of the size of the fetus and the volume of amniotic fluid in pregnant women.

In addition, the absence in the known tape of the possibility of registering the obtained data in the corresponding empty cells, opposite to the scale values corresponding to the height of the uterine fundus and typical for normal pregnancy, the safety of using the tape decreases, since an erroneous and / or late conclusion about the dynamics of fetal growth in of the examined pregnant woman. This can lead to late identification in a woman of the risk of fetal growth retardation, macrosomia, low and polyhydramnios, other pathology of fetal development due to late additional examination, termination of pregnancy and fetal death.

Known measuring tape designed to measure the height of the bottom of a pregnant uterus above the pubis, having a measuring scale and a sliding sleeve located in the center of the ruler (Pregnancy fundal-height measuring scale. CN 202920191 U China).

The disadvantage of the known measuring tape is the lack of the possibility of using the tape for registration and diagnostic purposes, which reduces the speed and safety of assessing the quality of pregnancy and the dynamics of fetal development. This can lead to late identification in a woman of the risk of fetal growth retardation, macrosomia, low and polyhydramnios, other pathology of fetal development due to late additional examination, termination of pregnancy and fetal death.

Known flexible measuring ruler, tape or tape measure, having black and red measurement marks on a yellow background for readability, used to measure size or distance, consisting of a tape made of fabric, plastic, fiberglass or metal tape with linear measuring markings (Tare measure. Https : //en.wikipedia.org/wiki/Tape_measure#: ~: text = A% 20tape% 20measure% 20or% 20measuring, is% 20a% 20common% 20measuring% 20tool. Found on the Internet 10/20/2020).

The disadvantage of the known flexible measuring ruler is that it is not intended for recording and evaluating the data obtained during the measurement. Therefore, the tape has a narrow range of application, low speed and safety of assessing the dynamics of the size of the fetus and the volume of amniotic fluid during pregnancy in pregnant women. This leads to a late identification in a woman of the risk of fetal growth retardation, macrosomia, low and polyhydramnios, other pathology of fetal development due to late additional examination, to termination of pregnancy and to fetal death.

Known measuring tape, consisting of a body, measuring tape, hook / needle, measuring tape holder, stationery holder, blade, the sharp side of which is located at the bottom of the holder, and between the axis of the holder and the sharp part of the blade there is a gap, and the pencil blade is installed with the ability to adjust the gap for the thickness of the rod of the stationery (RU 2679612 C1).

The disadvantage of the known measuring tape is that it is not a device for individual use, is not a registration and diagnostic device, therefore, it does not provide an urgent and safe diagnosis of pregnancy and the dynamics of the size of the fetus and the volume of amniotic fluid.

Known measuring ruler, combining three measuring scales: the first, which runs along one main working edge of the ruler, the second, which runs along the second main working edge of the ruler and has the same direction as the first scale, and the third scale, which runs between the first two scales in the opposite direction. direction, while the divisions of all three scales are aligned so that the beginnings of the first and second scales coincide and coincide with the end of the third, and the beginning of the third opposite scale coincides with the common end of the first and second scales, which makes it possible to universally measure on both working edges of the ruler in mutually opposite direction (RU 2017146559).

The disadvantage of the known measuring ruler is that it does not provide individual measuring, registration and diagnostic use, does not provide a high rate of assessment of the dynamics of the size of the fetus and the volume of amniotic fluid during pregnancy.

The objective of the invention is to expand the range of application, increase speed, efficiency, safety, accuracy and reduce labor intensity by making a tape for individual use, supplementing the measuring scale with three columns with through divisions, which are a continuation of the lines of scale values in centimeters, the presence in the far right column of indications about gestational age in weeks indicated in the cells located opposite the scale values corresponding to the height of the uterine fundus standing in the norm, the presence of two middle columns made with empty cells and with the possibility of registering in them the dates of studies of a pregnant woman in the left column and the timing of her pregnancy in weeks in the right column, with the possibility of selecting cells for this, located opposite the scale values corresponding to the height of the uterine fundus standing in this woman on the day of the study.

The technical result is the possibility of using the tape simultaneously as a measuring, recording and evaluating device, simplicity and ease of diagnosing the course of pregnancy, assessing the dynamics of fetal development and the volume of amniotic fluid, timeliness of identifying the risk of fetal growth retardation, the presence of macrosomia, malo- and micro-conduction, the need for additional examination a pregnant woman, regardless of the participation of a medical worker, the presence of an outpatient card of a pregnant woman, a normal gravidogram, without infection of a pregnant woman, termination of her pregnancy and fetal death.

The essence of the declared diagnostic measuring tape, designed to measure the height of the uterine fundus above the pubis in a pregnant woman, made of rubberized fabric, non-stretchable vinyl or soft plastic 150 cm long with a measuring scale on both sides, applied in the form of major divisions with an interval of 1 mm, having whole numerical values in centimeters, with the beginning of the scale reading on each side from the opposite end, with the ends covered with a metal coating, with the possibility of folding in a circle in the form of a roll, which can be squeezed and tied with a ribbon or folded into a round plastic box with a lid , lies in the fact that the tape is made for individual use, has a width of 5.0 cm, on one side of the tape along its left edge there is a 1 cm wide scale, to the right of it, on the remaining part of the tape width, there are three columns with through divisions, which are a continuation lines of scale values in centimeters, with one s the column is located on the right edge of the tape, is made with a width of 1 cm and in the cells located opposite the scale values corresponding to the height of the uterine fundus in the norm, contains an indication of the duration of pregnancy in the number of weeks, two columns are placed between the measuring scale and the rightmost column, have a width 1.5 cm each and empty cells for registration in the left column of the study dates of a pregnant woman, and in the right column of the dates of her pregnancy in weeks, while the columns are made with the possibility of selecting cells opposite the scale values corresponding to the heights of the uterine fundus in the examined pregnant woman discovered on the days of her examination.

Making the tape for individual use increases safety, since it eliminates the use of one tape for measuring many pregnant women and the infection of pregnant women from each other and from third parties. The fact is that the declared tape is intended not for general, but for personal use, therefore it is intended for its acquisition by each pregnant woman individually for the purpose of its personal use, and not for the purchase of the tape by a medical institution for public use.

The tape with a width of 5.0 cm expands the range of its application, since it allows you to place on the working surface a registration scale, a gravidogram substitute and columns with empty cells, the dimensions of which ensure the registration of the gestational age in weeks and the dates of the examination of a pregnant woman.

In the declared diagnostic measuring tape, its working side contains the following elements (indicating their width):

- measuring scale 1 cm wide,

- the rightmost column with filled divisions 1 cm wide,

- two middle columns with empty divisions, each 1.5 cm wide.

At the same time, the implementation of a 1 cm wide measuring scale and the extreme right column with a demonstration of the normal ratio of the values of the gestational age indicated in the cells located opposite certain values of the measuring scale is sufficient for using the tape as a measuring and evaluating device. In turn, the execution of a tape with a width of the middle columns of 1.5 cm provides registration in their empty cells of the dates of the studies performed and the timing of pregnancy in weeks.

The execution of the tape with the placement on the left edge of its working side of the measuring scale, and to the right of it three columns with divisions, which are the continuation of the lines corresponding to the values of the measuring scale in centimeters, increases speed, efficiency, accuracy and reduces labor intensity, since it provides automatic sequential filling (produced at each subsequent study) of the next, that is, "necessary", empty cells of the tape columns immediately immediately after measuring the height of the uterine fundus in a pregnant woman.

Placing the cells of the extreme right column with gestational periods in weeks opposite to certain values of the measuring scale, which correspond to the size of the height of the uterine fundus in the norm, expands the range of application increases speed, accuracy, safety, ease and reduces labor intensity, since it excludes the use of an outpatient card of a pregnant woman and a gravidogram ...

Making the cells of the two middle columns empty with the possibility of registering in the left of them the dates of the studies being carried out, and in the right periods of pregnancy in weeks in which the dimensions of the height of the uterine fundus in the studied pregnant woman are revealed, expands the range of application, increases efficiency, accuracy, safety, speed and reduces labor intensity, since it allows the use of empty columns of the tape for recording the results obtained instead of sheets of the outpatient card of a pregnant woman.

In addition, the presence of a column with empty cells intended for registering the dates of the studies being carried out further increases the efficiency, accuracy and safety, since it provides a clarification of the timing of pregnancy in the event of an unexpected change in the information about the date of the last menstruation in the studied pregnant woman. The fact is that changing the timing of pregnancy automatically changes the placement of this information in the cells and the ratio of the resulting diagram to the standard diagram.

Brief description of the drawing

The drawing of Figure 1 schematically shows the working side of the diagnostic measuring tape after removing the tape from the box and transferring it from the folded state to the stretched state.

FIG. 1. The working side of the diagnostic tape for a pregnant woman (top view). Measuring scale 1 is located on the left edge of the working surface of the tape, to the right of it there are columns with through divisions 2, which are a continuation of the whole scale values in centimeters, the divisions form cells 3, some of which are in the column located on the right edge 4, and corresponding to certain the values of the measuring scale are made with the factory indication of the timing of pregnancy in weeks 5, which form a normal diagram that replaces the gravidogram, between the left column and the scale are two empty columns, of which the left column 6 is intended for registration in its cells of research dates, and the right column 7 is intended for registration in its cells of the gestational age in weeks for the examined pregnant woman.

The device is used as follows.

Currently, for the initial assessment of the course of pregnancy, the dynamics of fetal growth and the volume of amniotic fluid, each pregnant woman periodically visits the antenatal clinic, where, at each regular visit, a medical worker measures her height of the uterine fundus using a conventional tape measure. At the same time, the same measuring tape is used to measure the height of the uterine fundus in all women attending antenatal clinics. The measurement is carried out by a medical professional who, at each visit to a woman, enters the results obtained in her outpatient card. The fact is that today there is no special measuring tape developed and proposed for individual measurement, registration and evaluation of the results obtained in a pregnant woman without her outpatient card.

Consequently, today pregnant women are not provided with special individual centimeter tapes that allow measuring the height of the fundus of the uterus, registering and evaluating the data obtained, regardless of the participation of a medical worker and the availability of outpatient records of pregnant women both in a medical institution and at home. Moreover, ordinary centimeter tapes of general use do not exclude infection of women from each other and from third parties, they require regular and thorough antiseptic treatment, which results in a progressive deterioration of the contrast of divisions and the visibility of the values of the measuring scale of the tape, which reduces the accuracy and speed. In addition, conventional centimeter tapes do not provide simultaneous measurement, registration and evaluation of the data obtained, simplicity and ease of diagnosis of the course of pregnancy, fetal growth dynamics and amniotic fluid volume, timeliness of identifying the risk of fetal growth retardation, the presence of macrosomia, mal- and micronutrient conduction, the need for additional examination a pregnant woman, regardless of the participation of a medical worker, the presence of an outpatient card of a pregnant woman, a normal gravidogram, without infection of a pregnant woman, termination of pregnancy and fetal death.

In this regard, in order to expand the range of application, increase safety, speed, accuracy, simplicity and reduce labor intensity, before the next measurement, each pregnant woman acquires a diagnostic measuring tape made with a measuring scale, two empty columns designed to register the dates of examinations and the timing of pregnancy, and one filled column, serving as an example of the final relationship between the timing of pregnancy and the size of the standing of the fundus in the norm, that is, a normal diagram.

To use the diagnostic measuring tape, a pregnant woman opens the lid of the box, which contains her individual measuring tape, and takes out the tape. She then exposes her abdomen and measures the height of the fundus with this tape. Before measuring, the working side of the tape is determined, and the end of the tape with the origin of the measuring scale on the working side, after which the tape is applied to the woman's stomach with the working side outward and the end of the tape with the origin of the scale directed towards the pubis. Immediately by palpation, the upper edge of the symphysis is determined, the end of the tape is applied to the place of its projection and fixed to it. Then the tape is stretched from this place of fixation towards the navel, after which, by palpation of the abdomen, the fundus of the uterus is determined, the place of projection on the skin of the abdomen of the fundus of the uterus is diagnosed, and the distance from the upper edge of the symphysis to this place is measured. The tape is removed from the woman's abdomen, placed on the table top of the writing table with the working side up to record and evaluate the result. Before this, the estimated gestational age of a pregnant woman is determined. Usually, the date of the last menstrual period is found out for this, and this date is used as a beacon for the theoretical calculation of the gestational age of the woman under study. This period in weeks is recorded in that cell of the right empty column of the tape, which is located opposite the value of the measuring scale corresponding to the revealed height of the uterine fundus in a pregnant woman. The date of this study is also written in the adjacent cell of the left empty column. After that, the correspondence of the location of the cells with the indicated periods of pregnancy is compared with the control cells located on the right edge of the working side of the tape and constituting a kind of control chart. If the locations of the hand-filled cells and the factory-filled cells are completely consistent, the course of pregnancy, the dynamics of fetal growth and the volume of amniotic fluid in the pregnant woman under study are assessed as normal. If there is a significant difference in the arrangement of hand-filled cells and factory-filled cells that make up a normal diagram, a recommendation is issued for an additional examination of the pregnant woman.

After completing the measurement of the height of the uterine fundus, registration and evaluation of the data obtained, the tape is rolled up, placed in a box, the box is closed with a lid, and then stored and transported as usual.

The proposed diagnostic measuring tape expands the range of application, increases speed, efficiency, safety, accuracy and reduces labor intensity due to the fact that the tape is made for individual use, has a width of 5 cm, is made with placement on the working side of the tape along its left edge of the measuring scale 1 cm, and to the right of it and parallel to it with the placement of two empty columns with a width of 1.5 cm and one column along the right edge of the tape with a width of 1 cm with divisions opposite the whole values of the scale in centimeters, indicating the dates of pregnancy in the cells of the extreme right column opposite to certain sizes of the height of the uterine fundus in the norm, the execution of two middle columns with the possibility of registering in the right of them the gestational age in weeks, in the left of the dates on which the corresponding dimensions of the height of the uterine fundus in the studied pregnant woman are revealed.

The fact is that the diagnostic measuring tape is made for individual use by each pregnant woman simultaneously and / or sequentially as a measuring, recording and diagnostic device, which ensures high accuracy, timeliness and ease of diagnosing the course of pregnancy, assessing the dynamics of fetal development and the volume of amniotic fluid independently from the participation of a medical worker, the presence of an outpatient card of a pregnant woman, a gravidogram characteristic of the course of a normal pregnancy, and also excludes infection of a pregnant woman.
