The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be understood that the medical monitoring device of the present invention is not limited to a monitor, but includes an invasive/noninvasive ventilator having a monitoring function, a nurse station, a central station, etc. The present application mainly uses a monitor as an example for explanation. As shown in FIG. 1, FIG. 1 provides a system framework diagram of a multi-parameter monitor. The multi-parameter monitor has a separate housing having a sensor interface area on a panel of the housing, in which a plurality of sensor interfaces are integrated for connecting with external physiological parameter sensor accessories 111, and a small-sized IXD display area, a display 119, an input interface circuit 122, an alarm circuit 120 (e.g., an LED alarm area), and the like. The parameter processing module is used for communicating with the host and getting electricity from the host, and is used for an external communication and power interface. The parameter processing module also supports an external parameter insertion module, a plug-in monitor host can be formed by inserting the parameter insertion module and is used as a part of the monitor, the plug-in monitor host can also be connected with the host through a cable, and the external parameter insertion module is used as an external accessory of the monitor.
The internal circuit of the parameter processing module is disposed in the housing, as shown in fig. 1, and includes at least two signal acquisition circuits 112 corresponding to physiological parameters, a front end signal processing circuit 113 and a main processor 115, the signal acquisition circuits 112 may be selected from an electrocardiograph circuit, a respiration circuit, a body temperature circuit, a blood oxygen circuit, a non-invasive blood pressure circuit, an invasive blood pressure circuit, and the like, the signal acquisition circuits 112 are respectively electrically connected to corresponding sensor interfaces for electrically connecting to the sensor accessories 111 corresponding to different physiological parameters, an output end of the signal acquisition circuit is coupled to the front end signal processor, a communication port of the front end signal processor is coupled to the main processor, and the main processor is electrically connected to an external communication and power interface. The various physiological parameter measuring circuits can adopt a common circuit in the prior art, a front-end signal processor completes the sampling and analog-to-digital conversion of the output signal of the signal acquisition circuit and outputs a control signal to control the measuring process of the physiological signal, and the parameters include but are not limited to: electrocardio, respiration, body temperature, blood oxygen, noninvasive blood pressure and invasive blood pressure parameters. The front-end signal processor can be realized by a single chip microcomputer or other semiconductor devices, for example, a mixed signal single chip microcomputer such as LPC2136 of PHLIPS company or ADuC7021 of ADI company can be selected, and the front-end signal processor can also be realized by an ASIC or an FPGA. The front-end signal processor may be powered by an isolated power supply, and the sampled data may be sent to the host processor via an isolated communication interface after being simply processed and packaged, for example, the front-end signal processor circuit may be coupled to the host processor 115 via the isolated power supply and communication interface 114. The reason that the front-end signal processor is supplied with power by the isolation power supply is that the DC/DC power supply is isolated by the transformer, which plays a role in isolating the patient from the power supply equipment, and mainly aims at: 1. isolating the patient, and floating the application part through an isolation transformer to ensure that the leakage current of the patient is small enough; 2. the voltage or energy when defibrillation or electrotome is applied is prevented from influencing board cards and devices of intermediate circuits such as a main control board and the like (guaranteed by creepage distance and electric clearance). The main processor completes the calculation of the physiological parameters and sends the calculation results and waveforms of the parameters to a host (such as a host with a display, a PC, a central station, etc.) through an external communication and power interface 116, which may be one or a combination of an Ethernet (Ethernet), a Token Ring (Token Ring), a Token Bus (Token Bus) and a local area network interface (lan interface) composed of a backbone Fiber Distributed Data Interface (FDDI) as these three networks, one or a combination of wireless interfaces such as infrared, bluetooth, wifi, WMTS communication, etc., or one or a combination of wired data connection interfaces such as RS232, USB, etc. The external communication and power interface 116 may also be one or a combination of a wireless data transmission interface and a wired data transmission interface. The host can be any computer equipment of a host computer of a monitor, an electrocardiograph, an ultrasonic diagnostic apparatus, a computer and the like, and matched software is installed to form the monitor equipment. The host can also be communication equipment such as a mobile phone, and the parameter processing module sends data to the mobile phone supporting Bluetooth communication through the Bluetooth interface to realize remote transmission of the data.
As shown in fig. 2, a processing system architecture for a single physiological parameter is provided. The same can be found in the above.
As shown in fig. 3, a networked system of monitors for use in a hospital is provided, by which data of the monitors can be integrally stored, patient information and nursing information can be centrally managed, and the patient information and the nursing information can be stored in association with each other, so that storage of historical data and associated alarm can be facilitated. In the system shown in fig. 3, a bedside monitor 212 may be provided for each patient bed, and the bedside monitor 212 may be the multi-parameter monitor or the plug-in monitor described above. In addition, each bedside monitor 212 can also be paired with a portable monitoring device 213 for transmission, the portable monitoring device 213 provides a simple and portable parameter processing module, and can be worn on the body of a patient to perform mobile monitoring corresponding to the patient, and physiological data generated by the mobile monitoring can be transmitted to the bedside monitor 212 for display after the portable monitoring device 213 is in wired or wireless communication with the bedside monitor 212, or transmitted to the central station 211 for a doctor or a nurse to view through the bedside monitor 212, or transmitted to the data server 215 for storage through the bedside monitor 212. In addition, the portable monitoring device 213 can also directly transmit the physiological data generated by the mobile monitoring to the central station 211 through the wireless network node 214 arranged in the hospital for storage and display, or transmit the physiological data generated by the mobile monitoring to the data server 215 through the wireless network node 214 arranged in the hospital for storage. It can be seen that the data corresponding to the physiological parameters displayed on the bedside monitor 212 may originate from a sensor accessory directly connected above the monitor, or from the portable monitoring device 213, or from a data server.
Referring to fig. 4, the physiological sign monitoring method for hemodynamics provided by the embodiment of the present invention is applied to a medical monitoring device, and is particularly suitable for a medical monitoring device including a display, and is used for displaying waveform monitoring information corresponding to physiological signs related to hemodynamics by using the display. The medical monitoring device may execute program instructions stored in the memory to implement a corresponding physiological sign monitoring method for hemodynamics.
The physiological sign monitoring method aiming at hemodynamics comprises the following steps:
in this embodiment, a processor in the medical monitoring device may first obtain physiological signs related to hemodynamics, the physiological signs including at least blood pressure and pulse rate, wherein the blood pressure may be non-invasive blood pressure, arterial pressure, central venous pressure, and/or the like.
Hemodynamics refers to the mechanics of blood flow in the cardiovascular system, and mainly studies blood flow volume, blood flow resistance, blood pressure, and their interrelationships. Blood is a fluid, and thus the basic principle of hemodynamics is the same as that of general hydrodynamics. However, because the vascular system is a relatively complex elastic pipeline system, and blood is liquid containing various components such as blood cells, colloidal substances and the like rather than ideal liquid, the hemodynamics not only has the common characteristics of general hydrodynamics, but also has the characteristics of the hemodynamics.
in this embodiment, the physiological sign sensor in the medical monitoring device may acquire historical data of at least one physiological sign parameter related to hemodynamics of the monitored subject within a preset time period. The preset time period may be preset by a user, for example, 8 hours or 24 hours, or may be set when the medical monitoring device leaves a factory, which is not limited herein.
The sensor is a detection device which can sense the measured information and convert the sensed information into an electric signal or other information in a required form according to a certain rule to output so as to meet the requirements of information transmission, processing, storage, display, recording, control and the like.
304, displaying a special monitoring interface for hemodynamics, wherein the special monitoring interface for hemodynamics at least comprises a first display area;

For easy understanding, please refer to fig. 5, fig. 5 is a schematic diagram of an interface of information related to hemodynamics according to an embodiment of the present invention, and as shown in the figure, when a user clicks on the "hemodynamics" module, a dedicated monitoring interface related to hemodynamics can be accessed. In practical application, a user can select a 'vital sign' interface, an 'infection' interface or a 'craniocerebral injury' special monitoring interface to view according to requirements, and waveform monitoring information related to a required slice is displayed on each special monitoring interface.
In this embodiment, the display in the medical monitoring device may display, in the first display area, the waveform monitoring information corresponding to the monitoring data of the hemodynamic-related physiological sign parameter based on the monitoring data of the hemodynamic-related physiological sign parameter.
For convenience of introduction, please refer to fig. 6, where fig. 6 is an interface schematic diagram of a first display area in an embodiment of the present invention, as shown in the figure, the first display area is a portion S1 indicated by a dashed box, related waveform monitoring information can be displayed in the first display area, 5 pieces of waveform monitoring information in the figure are one schematic diagram, and in an actual application, other numbers of waveform monitoring information may also be provided.
It should be noted that the execution sequence between step 301 and step 305 is not limited in the present invention.
In the technical scheme provided by the embodiment of the application, a physiological sign monitoring method for hemodynamics is provided, and the method includes the steps of firstly, acquiring a physiological sign related to hemodynamics of a monitored subject, wherein the physiological sign related to hemodynamics at least includes blood pressure and heart rate, or the physiological sign related to hemodynamics at least includes blood pressure and pulse rate, then acquiring monitoring data corresponding to the physiological sign related to hemodynamics, generating waveform monitoring information corresponding to the physiological sign related to hemodynamics based on the monitoring data corresponding to the physiological sign related to hemodynamics, and displaying a special monitoring interface for hemodynamics, wherein the special monitoring interface for hemodynamics at least includes a first display area, and finally displaying the waveform monitoring information corresponding to the physiological sign related to hemodynamics in the first display area. Through the mode, the medical monitoring equipment can directly display the waveform monitoring information related to the hemodynamics according to the requirements of the user, slice display of the physiological parameters of the hemodynamics is realized, so that the time for the user to search the waveform monitoring information related to the hemodynamics one by one is saved, and the operability of the scheme is improved.
Optionally, on the basis of the embodiment corresponding to fig. 4, in an optional embodiment of the method for monitoring physiological signs for hemodynamics provided by the embodiment of the present invention, the physiological signs related to hemodynamics further include one or more of a pulse pressure variation rate, a cardiac output and a peripheral vascular resistance index.
In this embodiment, it is specifically explained that the physiological parameters related to hemodynamics include: heart Rate (HR), non-invasive blood pressure (NIBP), arterial pressure (ART), Central Venous Pressure (CVP), pulse pressure variation rate (PPV), Cardiac Output (CO) (e.g., continuous cardiac output, CCO), and peripheral vascular resistance index (SVRI) parameters.
Waveform monitored information of the physiological signs related to hemodynamics can be displayed on the first display area for a period of time, wherein the waveform monitored information can be short trend waveform information, for example, waveform information within 8 hours belongs to the short trend waveform information. Or may be long trend waveform information such as within 24 hours of waveform care information belonging to the long trend waveform information.
In an embodiment, the physiological sign monitoring method for hemodynamics further comprises:
displaying a graphical touch button in a special monitoring interface for hemodynamics;
acquiring a switching instruction input by a user through a graphical touch button;
and determining to display the waveform monitoring information corresponding to the physiological signs related to the hemodynamics in the first time period or display the waveform monitoring information corresponding to the physiological signs related to the hemodynamics in the second time period based on the switching instruction.
For example, as shown in the "<" button in fig. 5-7, the hemodynamic dedicated monitoring interface currently displays waveform monitoring information (i.e., short trend) within 8 hours (first time period), and when the user touches the "<" button, the hemodynamic dedicated monitoring interface switches to display waveform monitoring information (i.e., long trend) within 24 hours (second time period).
It can be understood that HR refers to the number of heartbeats per minute of a normal person in a resting state, also called resting heart rate, which is generally 60-100 beats/minute, and may cause individual differences due to age, gender or other physiological factors. Generally, the smaller the age, the faster the HR, the slower the heart beat in the elderly than in the young, and the faster the HR in women than in men of the same age, are normal physiological phenomena. Under a quiet state, the normal HR of an adult is 60-100 times/min, and the ideal HR is 55-70 times/min.
NIBP also can be called as automatic noninvasive pressure measurement, which means that a special air pump is used to automatically control the cuff to inflate, and pressure measurement can be performed at a fixed time interval, so that the NIBP is the most widely used blood pressure monitoring method in Intensive Care Units (ICUs) and anesthesia surgeries.
ART is one of the important indicators of circulatory function, and too high or too low ART affects blood supply to various organs and cardiac load. If ART is too low, blood supply to organs is reduced, especially blood supply insufficiency of important organs such as brain and heart, and serious consequences are caused. If the blood pressure is too high, the burden on the heart and blood vessels becomes excessive. Patients with long-term hypertension often suffer from compensatory cardiac hypertrophy, cardiac insufficiency, and even heart failure. The blood vessel is under high pressure for a long time, the blood vessel wall is pathologically changed, and even the rupture can cause serious consequences such as cerebral hemorrhage, and the like, so that the relatively stable state that ART is close to normal is very important to keep.
CVP refers to the pressure in the right atrium and the thoracic segments of the superior and inferior vena cava. It can judge the comprehensive condition of blood volume, cardiac function and blood vessel tension of patient, and is different from peripheral venous pressure. The latter is affected by the valves in the venous lumen and other mechanical factors, and therefore cannot reflect the blood volume and cardiac function exactly.
PPV is defined in the fluid management of patients as the rate of arterial blood pressure variation, and infusion responsiveness is assessed by means of cardiopulmonary interactions during mechanical ventilation. Arterial PPV from arterial waveform analysis and pulsatile output variation from pulse contour analysis have proven to be very predictive of infusion responsiveness.
CO refers to the amount of blood per minute that is ejected into the aorta or pulmonary artery from either the left or right ventricle. The left and right ventricular outputs are substantially equal. The blood volume output by each beat of the ventricle is called the stroke volume, the volume is about 70 ml when a human body is at rest, if the HR is averagely 75 times per minute, the volume of the blood output per minute is about 5000 ml, namely CO per minute, and the CO is an important index for evaluating the efficiency of the circulatory system. CO is largely compatible with the metabolism of systemic histiocytes. CCO refers to CO obtained over a continuous period of time. The CO in this embodiment may specifically include CCO.
SVRI is related to peripheral vascular resistance (SVR), which is a quantitative indicator that diagnoses and reflects levels of afterload in the circulating blood stream group and the heart, and the decrease in vessel radius in the group caused by the increased vasomotor response and the progressively aggravated vascular remodeling of the resistance vessels, which is a key factor in the increase of SVR. An increase in SVR increases blood pressure, exacerbating afterload levels and oxygen consumption of the heart.
In another embodiment of the present invention, the waveform monitoring information includes one or more physiological parameters related to hemodynamics. Through the mode, one or more of the heart rate, the non-invasive blood pressure, the arterial pressure, the central venous pressure, the pulse pressure variation rate, the cardiac output (such as continuous cardiac output) and the peripheral vascular resistance index parameters can be directly displayed according to the requirements of medical workers, so that the time for the medical workers to search physiological sign parameters related to the parameters one by one is saved, and the application efficiency is greatly improved.

It will be appreciated that in practice, one or more of a Hemosight interface entry, a CVP2-5Tool interface entry, and a PLR guide Tool interface entry may be included.
In addition, a craniocerebral injury integrated coma index scoring entry, a rescue Sepsis exercise (SCC) treatment guideline tool, a Sequential Organ Failure Assessment (SOFA) scoring tool entry, and the like may also be displayed in the second display region.

The leg lifting posture of the patient is adjusted by adjusting the sickbed, and the change of the observation parameters is observed and recorded. 3. The patient was adjusted to recover the semi-supine position and checked to see if the observation parameters recovered from the baseline.
The CVP2-5Tool interface inlet is used for providing real-time CVP parameter trend display in the process of fluid infusion of a patient by a user, providing an auxiliary Tool based on a CVP2-5 principle commonly used clinically, presenting CVP parameter change in the fluid infusion process in real time, intelligently prompting whether fluid infusion can be performed or not, and helping a doctor to complete fluid infusion conveniently and accurately.

The vital signs are used to determine the severity and criticality of the patient. There are mainly heart rate, pulse, blood pressure, blood oxygen saturation, respiration rate, pain, body temperature, changes in pupillary and corneal reflexes, etc. They are the pillars that maintain the normal movement of the body, and are not the least, and either abnormality can cause serious or fatal diseases, and some diseases can also cause the changes or aggravation of these four major signs.
Waveform monitoring information of at least one basic vital sign related physiological sign parameter can be displayed on the first display area for a period of time, wherein the waveform monitoring information can be short trend waveform information, for example, waveform information within 8 hours belongs to the short trend waveform information. Or may be long trend waveform information such as within 24 hours of waveform care information belonging to the long trend waveform information.
It can be understood that HR refers to the number of heartbeats per minute of a normal person in a resting state, also called resting heart rate, which is generally 60-100 beats/minute, and may cause individual differences due to age, gender or other physiological factors. Generally, the smaller the age, the faster the HR, the slower the heart beat in the elderly than in the young, and the faster the HR in women than in men of the same age, are normal physiological phenomena. Under a quiet state, the normal HR of an adult is 60-100 times/min, and the ideal HR is 55-70 times/min.
SpO2 is the volume of oxygenated hemoglobin bound by oxygen in the blood as a percentage of the total available hemoglobin volume, i.e., the concentration of blood oxygen in the blood, which is an important physiological parameter of the respiratory cycle. The metabolism process of human body is biological oxidation process, and the oxygen required in the metabolism process is passed through respiratory system and fed into human body blood, and combined with hemoglobin in blood erythrocyte to form oxygenated hemoglobin, then fed into various tissue cells of human body. The ability of blood to carry transported oxygen is measured by the blood oxygen saturation.
ART is one of the important indicators of circulatory function, and too high or too low ART affects blood supply to various organs and cardiac load. If ART is too low, blood supply to organs is reduced, especially blood supply insufficiency of important organs such as brain and heart, and serious consequences are caused. If the blood pressure is too high, the burden on the heart and blood vessels becomes excessive. Patients with long-term hypertension often suffer from compensatory cardiac hypertrophy, cardiac insufficiency, and even heart failure. The blood vessel is under high pressure for a long time, the blood vessel wall is pathologically changed, and even the rupture can cause serious consequences such as cerebral hemorrhage, and the like, so that the relatively stable state that ART is close to normal is very important to keep.
BP is the lateral pressure acting on the wall of a blood vessel per unit area when blood flows in the blood vessel, and is the motive force for pushing the blood to flow in the blood vessel. In different vessels are called arterial blood pressure, capillary blood pressure and venous blood pressure, respectively, and the blood pressure is commonly referred to as arterial blood pressure of the systemic circulation.
RR represents the number of milligrams of oxygen consumed or carbon dioxide released per gram of living tissue per hour. The magnitude of RR may reflect the magnitude of metabolic activity of an organism. RR per minute varies with age, sex, and physiological state, RR at calm in adults is about 16-20 times per minute, in children is about 20 times per minute, and generally women are 1-2 times faster than men. It is also an important diagnostic basis for doctors in clinical diagnosis.
PR refers to the frequency of arterial pulsations. The pulse rate is affected by age, sex, exercise and mood. Adults have more than 100 beats per minute called tachycardia and less than 60 beats per minute called bradycardia. There are many diseases in the clinic, especially heart disease, which can cause pulse rate changes. Therefore, measuring PR is an indispensable examination item for the patient.
TEMP can vary slightly within the normal range, for example: TEMP is relatively high in the early morning of the afternoon, but generally differs by less than 1 deg.C; after meals, work or strenuous exercise, TEMP can also rise slightly; TEMP can be slightly increased by factors such as sudden high-temperature environment entering or emotional agitation; women have slightly higher TEMP than normal during ovulation and pregnancy. Slight TEMP difference exists in different age stages, for example, children have higher TEMP than adults due to high metabolic rate; the old also has a slightly lower TEMP than young and strong years due to the low metabolic rate.
The waveform monitoring information also includes one or more physiological sign parameters associated with the underlying vital sign. Through the mode, one or more of heart rate, oxyhemoglobin saturation, arterial pressure, body temperature, blood pressure, respiratory rate and pulse rate can be directly displayed according to the requirements of medical personnel, so that the time for the medical personnel to search physiological sign parameters related to the parameters one by one is saved, and the application efficiency is greatly improved.
