Description

Monitor for dynamic flow of amniotic fluid and blood during parturient labor

Technical Field

The utility model relates to a medical equipment, especially a amniotic fluid blood dynamic flow monitor during parturient labor.

Background

When the parturient partures, the amnion is ruptured, the amniotic fluid flows out, and the doctor collects the amniotic fluid by means of the amniotic fluid collecting bag. The color of amniotic fluid is usually colorless or yellowish. During delivery of a parturient, the uterus may develop laceration bleeding, which is usually dark red due to uterine contractions after the flow of amniotic fluid, and red of various shades after mixing with the amniotic fluid.

Doctors often judge the bleeding degree of the lying-in women through visually recognizing the color in the amniotic fluid collecting bag, and if serious blood loss of the lying-in women occurs, related blood transfusion and other rescues need to be carried out.

But the blood outflow volume can not be accurately judged by visual identification, and the continuous slow bleeding is not easy to be perceived. Requiring the judgment of a doctor or nurse's personal experience. The bleeding degree of the lying-in woman can be indirectly monitored only by means of blood pressure and pulse monitoring. When abnormal conditions occur in the pulse and the blood pressure, the doctor can be indirectly reminded of the attention.

At present, a simple and convenient reminding mode or an examination instrument capable of directly examining the bleeding volume of a puerpera does not exist.

Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings.

In general, a parturient is produced in such a sequence that an amnion is ruptured first, amniotic fluid flows out, most of the amniotic fluid flows out preferentially, and then a small amount of blood flows out due to separation of a placenta from a uterine wall of the parturient, and the like. However, during childbirth, it may occur that the abdominal pressure is too high, which may cause rupture of the uterine wall or vaginal rupture to produce bleeding, and even may cause rupture of the main blood vessels due to improper location of the placenta or other conditions, resulting in massive or abdominal bleeding.

In traditional parturient delivery monitoring, blood pressure and heartbeat level are detected, the blood loss condition of the parturient is indirectly judged through physiological indexes, and corresponding blood transfusion and other rescues are carried out when the blood pressure of the parturient is too low and the heart rate is irregular. However, this method is a post-treatment remedy and cannot effectively monitor the amount of blood lost by the parturient during the childbirth process in real time. It is necessary to rely on the judgment of the obstetrician and nurse, which requires some experience and attention.

As shown in fig. 1 and 2, the utility model discloses a carry out the blood content analysis to lying-in woman's exhaust amniotic fluid and blood water mixture, judge lying-in woman's blood loss volume, compare in foretell judgement method more direct, and need not to rely on obstetrician's real-time attention.

Amniotic fluid blood dynamic flow monitor during parturient's labor, constitute by test tube, color probe, flowmeter, computer and display, it carries out flow and color control through the test tube on the amniotic fluid collection bag of lying-in woman's labor below and intercommunication collection bag, comes further estimation blood volume what.

Specifically, since amniotic fluid is usually colorless or yellowish, and the bleeding color is usually bright red or deep red, the mixture of amniotic fluid and blood will change its color depending on the proportion of blood, especially for the special monitoring of blood red. Carrying out color value evaluation, particularly red gradation evaluation on the liquid flowing through the detection tube through a color probe, and analyzing the proportional relation of blood in the liquid mixture through artificial intelligence deep learning; and the real-time flow monitoring is added, so that the actual bleeding volume and amniotic fluid flow of the puerpera can be further calculated.

Amniotic fluid blood dynamic flow monitor during parturient's labor, link to each other with the detection box, the detection box is a sealed shading container, inside includes colour probe, LED light source, flowmeter and discernment colour chip, the flowmeter is digital flowmeter. The detecting tube of the detecting box is connected with the pad collecting tube, and the signal of the flowmeter and the digital signal of the color probe are transmitted back to the microcomputer through the signal wire.

The color probe adopts a TCS3200 series color identification chip, the TCS3200D sensor is provided with red, green and blue filters and a clear 4 filters, the filter mode can be selected through the high and low levels of pins S2 and S3 of the color probe, and the color probe is provided with an LED illumination light source. The identification color card is used as the background of the detection tube and is arranged on the side opposite to the color identification chip.

The utility model discloses in, the colour probe mixes the liquid from the amniotic fluid blood water of the test tube of flowing through, behind the test tube that has the discernment colour chip, gathers RGB colour relation at the colour probe, compares through a large amount of experimental data and carries out the degree of depth study with artificial intelligence after, has obtained an approximate accurate corresponding coefficient proportion table. The corresponding relationship is shown in fig. 3.

Through the proportional relation presetting table, the microcomputer automatically converts the color RGB value of the amniotic fluid and blood mixed liquid into the gear corresponding to the proportion occupied by blood, automatically calculates the current real-time bleeding amount and the accumulated bleeding amount according to the flow obtained by the flowmeter, and displays the real-time bleeding amount and the accumulated bleeding amount on the display through a computer program.

The software program interface is displayed on the display, the alarm function is realized, the early warning value is set in the program, and when the real-time bleeding amount or the accumulated bleeding amount exceeds the early warning value, an alarm is given out to remind doctors and nurses to pay attention.

In clinical test, respectively taking a certain proportion of the blood and the amniotic fluid to mix, flowing through the detection box, obtaining measurement data through calculation, wherein a certain error exists between the data and the actual blood volume taken, after multiple comparisons, the actual error measurement is shown in figure 4, the error is learned and taught through an artificial intelligence technology, the gear color numerical value of the proportional relation preset table is modified, and after repeated comparisons, a corresponding coefficient proportion table with the error value smaller than 10% is obtained.

Because the bleeding color of venous blood is darker, and the color of arterial blood is bright red, a certain error range exists in the actual bleeding proportion, and the mixed liquid simulation experiment of different proportions proves that the error of the accumulated blood loss is less than 10 percent, so that the clinical application can be met.

The use of such test devices has been much more accurate than visual testing by doctors and nurses. Particularly, the device can remind people of continuous small-flow bleeding, namely the situation that the wound in the uterus or the vagina can not be healed continuously.

This lying-in woman is produced amniotic fluid blood dynamic flow monitor networking back, can also pass through other removal receiving terminals such as wireless signal transmission to cell-phone or flat board, shows through APP software, realizes remote monitoring.
