[0001] POSTPARTUM HAEMORRHAGE CONTROL AND MONITORING SYSTEM

[0002] Technical Field

[0003] The invention relates to a postpartum haemorrhage control and monitoring system, in the field of health, especially in obstetrics / midwifery departments, that minimises possible fatal consequences by ensuring that vaginal bleeding that may occur after birth is controlled and monitored by the mother or specialists, bleeding data is digitally processed after being collected in the data pool, and these data are transferred online to the responsible specialist or personnel.

[0004] State of the Art

[0005] Postpartum uterine bleeding can occur when the uterine muscles fail to contract sufficiently after birth to cut off the flow of blood previously circulating in the uteroplacental space to nourish the unborn child (fetus). This lack of contraction is called atony (lack of tone).

[0006] The mechanism by which contraction of the uterine muscles typically cuts off blood flow is the cross-hatch configuration of the myometrium, which by contraction of its muscles effectively compresses the arterial vessels passing through the cross-hatch sections. In some cases, atony can cause arterial vasculitis.

[0007] The rate of bleeding can vary from one drop to what is described as a tap flow, which can have a flow rate similar to the flow rate of the placenta to the fetus at full term (approximately 750 ml / min).

[0008] Postpartum haemorrhage, or excessive uterine blood loss after birth, is the leading cause of maternal death worldwide, with more than 125,000 mothers dying each year.

[0009] The inability to control postpartum bleeding may require a woman to receive multiple blood transfusions and, in severe cases, a complete hysterectomy.

[0010] Accordingly, it is desirable to control such postpartum haemorrhage at its onset, if possible. The cause of postpartum haemorrhage, in about 80% of cases, is uterine atony, which is the inability of the woman's uterus to contract after giving birth to the child. Risk factors for uterine atony include prolonged labour, preeclampsia, and multiparity.

[0011] Postpartum haemorrhage has traditionally been treated using oxytoxic agents, hormonal agents that induce muscle contraction. Unfortunately, studies have increasingly shown that oxytoxic agents do not significantly reduce the incidence of postpartum haemorrhage or the amount of blood lost. Some studies have even shown that oxytoxic agents are overused and that this treatment increases the risk of uterine atony.

[0012] Current medical devices and surgical procedures have also proven inadequate and / or overly invasive in reducing postpartum haemorrhage or the amount of blood lost.

[0013] Every woman who gives birth is at potential risk of postpartum haemorrhage. Biological and physiological evaluation is only a part of the event. Bleeding that starts within 24 hours after vaginal delivery is called early or primary postpartum haemorrhage, while bleeding that starts later and continues up to 12 weeks after birth is called late or secondary postpartum haemorrhage. Secondary postpartum haemorrhage is less common than primary postpartum haemorrhage and affects 1 -3% of all births. Certain classifications are used to understand blood loss. These are measured by parameters such as the amount of blood loss and the rate of blood loss.

[0014] Postpartum haemorrhage is an important cause of maternal death, especially in developing countries. As for the serious illness of the mother, postpartum haemorrhage is a common problem in both developed and developing countries. According to the World Health Organization (WHO), obstetric haemorrhage occurs in 10.5% of all live births. In 2000, approximately 13,795,000 women had to deal with postpartum haemorrhage. Approximately 132,000 maternal deaths occurred directly due to haemorrhage. This accounts for 28% of direct maternal deaths. In order to minimise maternal mortality due to postpartum haemorrhage, it is necessary to consider every puerperal woman as one with haemorrhage potential and to implement interventions to prevent haemorrhage rather than treat it. Knowing the criteria for evaluating postpartum haemorrhage is extremely important for the follow-up process to be effective and timely. Calculation of the amount of blood loss is the main criterion in the evaluation. In our country, when there is no problem, mothers are discharged 12-24 hours after vaginal birth and within 3-5 days after cesarean section. In general, for cases without complications, the hospital stay is accepted as 24 hours after vaginal birth and 48 hours after cesarean section. Having the mother in the hospital for the first 24 hours after birth may be sufficient to prevent emergent complications. However, this period is not sufficient to detect problems in cases where mothers are not monitored by a nurse or midwife at home during the postpartum period.

[0015] Since postpartum haemorrhage control cannot be monitored to certain standards, the World Health Organization and international guidelines recommend haemorrhage control with certain classifications for the first 24 hours after birth. However, there is no system or model in which the mother can monitor her own bleeding after 24 hours and transmit this data to the doctor online. The postpartum haemorrhage control and monitoring system is also an efficient and practical solution for midwives who will monitor the postpartum haemorrhage of puerperal women and postpartum mothers.

[0016] Brief Description of the Invention

[0017] The invention relates to a postpartum haemorrhage control and monitoring system, in the field of health, especially in obstetrics / midwifery departments, that minimizes possible fatal consequences by ensuring that vaginal bleeding that may occur after birth is controlled and monitored by the mother or specialists, bleeding data is digitally processed after being collected in the data pool, and these data are transferred online to the responsible specialist or personnel.

[0018] The Aim of the Invention

[0019] Postpartum Haemorrhage Control and Tracking System provides follow-up of postpartum 0-4 weeks in terms of bleeding. After puerperal woman or the midwife who follows the puerperal records the bleeding amount information manually on a designed visual card on a daily basis, these data are transmitted to the system as digital data. By means of the user interfaces defined in the system, this data is transmitted to the specialist / doctor and online control and follow-up is carried out. Thus, it is aimed to contribute to the reduction of maternal mortality and morbidity rates due to postpartum haemorrhage. This control and follow-up system, which is the subject of the invention, aims to reduce time and cost expenses by reducing examination and hospitalisation rates by ensuring continuous and online patient follow-up by the midwife / doctor.

[0020] An aim of the invention is to facilitate the monitoring of postpartum haemorrhages that may occur in postpartum women and to produce fast and efficient solutions by bringing the mother and the healthcare professional together through a common digital platform.

[0021] An aim of the invention is to provide the function of monitoring the mother remotely, as it can be operated via smart devices by means of its mobile application. An aim is to provide convenient opportunities for mothers who live in regions where access to the hospital is difficult or who want to be followed up from home after birth.

[0022] An aim of the invention is to improve the follow-up and analysis process by collecting bleeding data up to the 4thweek after birth in a single place and enabling these data to be analysed on a daily / weekly basis by the relevant specialist or doctor.

[0023] An aim of the invention is to provide a system that can be used to collect blood discharged from the body of a female patient during obstetric surgery procedures and postpartum surgery procedures and to automatically detect postpartum haemorrhage in a female patient from beginning to end. an aim of the invention is to reduce the workload of both mothers and healthcare personnel by reducing hospitalisation rates / duration by means of the remote follow-up and monitoring function.

[0040] Detailed Description of the Invention

[0041] In this detailed description, the preferred embodiments of the system that is the subject of the invention relates to a postpartum haemorrhage control and monitoring system (10), which, in the field of health, especially in obstetrics / midwifery departments, minimizes possible fatal consequences by only ensuring that vaginal bleeding that may occur after birth is controlled and monitored by the mother or specialists, data on the amount of bleeding and colour change, pad changing frequency are digitally processed after being collected in the data pool, and these data are transferred online to the responsible specialist or personnel.

[0042] Based on the fact that postpartum haemorrhage control is still not monitored to certain standards, it is recommended that haemorrhage control be carried out with certain classifications for the first 24 hours after birth, according to the World Health Organization and international guidelines / directives. However, there is no material / platform that allows the mother to self-monitor her bleeding 24 hours after birth. Postpartum bleeding control application is a useful solution for midwives who will monitor the bleeding of puerperal women and postpartum mothers.

[0043] The 6-week period after birth is the puerperal period, and women who are in this process are called puerperal. The system (10) enables the monitoring of bleeding that may occur in the puerperal period after birth and the control of this data by experts registered / assigned to the system (10).

[0044] The system (10) that is the subject of the invention comprises;

[0045] • smart devices such as computers, mobile phones and tablets belonging to users (11 ),

[0046] • server (12) that provides content service to smart devices (11 ) via communication medium,

[0047] • a database (13) that works with the server (12) and stores puerperal or specialist physician information and postpartum haemorrhage data entered by the mother, and

[0048] • an application (14) that can be downloaded to smart devices (11 ) via the server (12), ensures that postpartum bleeding control data contained in the server (12) is presented to users / experts, run on a smart device (11 ) for 4 weeks, primarily in the first 24 hours after birth, and enables the mother to control and monitor postpartum bleeding on her own and share this data with the relevant specialist(s).

[0049] The application (14), which serves in the system (10) via the server (12) and is installed on the smart devices (11 ), has many interfaces.

[0050] Application (14), the schematic representation of which is presented in Figure 2 comprises;

[0051] • the sign-up screen (41 ), which allows users to log in to the application (14) by creating a user name (email address) and password in order to create a user registration,

[0052] • the authorised view screen (42), which allows the bleeding control data of the puerperal woman to be followed up at the end of birth to be checked online remotely by specialists at the FHC or the hospital, • the puerperal user screen (43), which allows the puerperal woman to enter data on the bleeding amount, colour scale and pad frequency into the system (10),

[0053] • colour scale screen (44), which allows the bleeding data to be manually observed daily by the specialist or the puerperal patient and determined as a colour scale and entered into the system (10),

[0054] • pad change frequency screen (45), via which the information on pad change frequency is entered by the specialist or the puerperal patient, and

[0055] • bleeding measurement screen (46) via which the data on amount of bleeding is entered by the specialist or the puerperal patient.

[0056] The application (4) creates a digital interface where women, especially postpartum mothers, midwives and gynecologists can meet on a common platform and control postpartum haemorrhage.

[0057] After postpartum discharge, the mother downloads the application (14) and enters visual postpartum bleeding control information into the system (10) via the puerperal user screen (43) on a daily basis for 4 weeks. These data entered into the system (10) are transmitted to the authorised view screen (42) of the specialist in the FHC (Family Health Care) or hospital, and the midwife tracks the mother's daily bleeding data online.

[0058] The bleeding control card shown in Figure 3 is embedded in the puerperal user screen (43), and the bleeding data are scored and evaluated by the midwife or responsible official. When the risk score is high in terms of bleeding colour change, pad changing frequency and bleeding amount data, the midwife / specialist can reach the puerperal patient via phone or SMS and provide information.
