Specific embodiment

Embodiments of the present invention will be further described with reference to the accompanying drawing.

In general, general puerpera's production sequence is that amnion first ruptures, and amniotic fluid outflow, most of amniotic fluid can be preferential Outflow will cause a small amount of blood outflow since placenta separates etc. with the uterine wall of puerpera later.But in the progress of labor, It can occur to cause uterine wall rupture or colporrhexis generates bleeding abdominal pressure is excessively high, or even since site is not right, or Other situations of person cause main blood vessel to burst, cause big bleeding or abdominal cavity hemorrhage.

In traditional parturient childbirth monitoring, the detection to blood pressure and heartbeat level is relied on, is judged indirectly by physical signs The blood loss situation of puerpera, when puerpera's hypopiesia, heart murmur, carry out the rescues such as corresponding blood transfusion.But this method category In post, cannot the lying-in woman during delivery of effective monitoring in real time blood loss.Need to rely on sentencing for obstetrician and nurse Disconnected, this judgement needs certain experiences and attention.

The present invention analyze containing blood volume by amniotic fluid and watery blood mixture that puerpera is discharged, to judge the blood loss of puerpera Amount, it is more direct compared to above-mentioned judgment method, and the real-time concern without relying on obstetrician.

As shown in Figure 1 and Figure 2, amniotic fluid watery blood dynamic flow monitor when puerpera of the present invention produces, by detection pipe, face Color probe, flowmeter, microcomputer and display composition, it passes through on the watery blood amniotic fluid collecting bag and connection collecting bag for producing pad lower section Detection pipe carry out flow and color monitoring, come further estimate blood volume number.

Specifically, being scarlet or dark red, blood since amniotic fluid is usually colourless perhaps faint yellow and usual bleeding color Water and amniotic fluid mixture, can according to watery blood proportion number and the change of color occurs, especially to sanguine dedicated Monitoring.Color-values assessment is carried out to the liquid for flowing through detection pipe by color probe, especially red gradation assessment passes through Artificial intelligence deep learning analyzes the proportionate relationship that blood accounts for liquid mixture；In addition with real-time traffic monitoring, Ke Yijin One step extrapolates the practical amount of bleeding and amniotic fluid flow of puerpera.

Amniotic fluid watery blood dynamic flow monitor when puerpera of the present invention produces is connected with detection box, and detection box is one Light-shielding container is sealed, inside includes that color probe, LED light source, flowmeter and identification colour atla, flow are calculated as digital flowmeter. The detection pipe for detecting box is connected with pad collecting pipe is produced, and is returned the digital signal that the signal of flowmeter and color are popped one's head in by signal wire It is transmitted to microcomputer.

Color probe uses TCS3200 color spectrum identification chip, TCS3200D sensor have RGB and 4 kinds of optical filters are removed, filter mode can be selected by the low and high level of its pin S2 and S3, and carried LED photograph Mingguang City source.Identify the colour atla side opposite by color identification chip as the background of detection pipe.

In the present invention, color probe passes through the detection with identification colour atla from the amniotic fluid watery blood mixed liquor for flowing through detection pipe Guan Hou pops one's head in color and acquires RGB color relationship, and comparing and artificial intelligence carry out deep learning through a large number of experiments Afterwards, a substantially accurate coefficient of correspondence ratio table has been obtained.Its corresponding relationship is as shown in Figure 3.

By proportionate relationship preset table, microcomputer automatically converts the color rgb value of amniotic fluid watery blood mixed liquor to shared by blood According to gear corresponding to ratio, and the flow obtained according to flowmeter is calculated current real-time amount of bleeding and accumulation automatically Amount of bleeding, and shown over the display by computer program.

Software program interface is shown on display, and there is warning function, early warning value is set in program, when real-time amount of bleeding Or accumulation amount of bleeding is more than early warning value, is sounded an alarm, and doctor and nurse's concern are reminded.

In clinical trial, a certain proportion of watery blood is taken to mix with amniotic fluid respectively, flow through detection box, survey is obtained by calculation Data are measured, there is a certain error between the data and the practical blood volume taken, and after repeatedly comparing, which is surveyed Amount is as shown in figure 4, the error is learnt and looked after and guided by artificial intelligence technology, the gear of modification aforementioned proportion relationship preset table Color data obtains coefficient of correspondence ratio table of the error amount less than 10% after comparing repeatedly.

Since venous blood bleeding color is deeper, and arterial blood color is more scarlet, and there are certain errors for practical bleeding ratio Range is proved by the mixed liquor simulated experiment of different proportion, is accumulated blood loss error less than 10%, has been able to satisfy clinic and has answered With.

The use of the detection device detects by visual observation relative to doctor and nurse, accurate many.Especially pair The case where small flow bleeding of duration, i.e., uterus or intravaginal wound can not persistently heal, it can accomplish to remind in time.
