Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular, to an electrocardiogram monitoring device for a medical transfer bed, a medical transfer bed, and a method for using the same. Background Art

[0002] An electrocardiogram monitor is a sophisticated medical instrument that can simultaneously monitor physiological parameters such as a patient's dynamic electrocardiogram pattern, respiration, body temperature, blood pressure, blood oxygen saturation, and pulse rate, and can compare them with known set values. If the values exceed the standard, an alarm can be issued. Electrocardiogram monitoring is a means of monitoring the electrical activity of the heart. An ordinary electrocardiogram can only simply observe the short-term electrocardiogram activity at the time of electrocardiogram recording. Electrocardiogram monitoring is a non-invasive monitoring method that continuously observes and monitors the electrical activity of the heart through a display screen. It can timely observe the patient's condition, provide reliable and valuable electrocardiogram activity indicators, and guide real-time treatment. Therefore, it has important application value for patients with abnormal electrocardiogram activities, such as acute myocardial infarction and various arrhythmias.

[0003] When in use, an electrocardiogram monitor needs to be placed beside the patient, generally on a dedicated electrocardiogram monitoring cart. Although an ordinary electrocardiogram monitoring cart is equipped with wheels and is easy to move, there are many connecting wires on the electrocardiogram monitor. When a patient on a transfer bed needs electrocardiogram monitoring, on the one hand, the length of the connecting wires is not enough, and on the other hand, the connecting wires are easily pulled and damaged during transportation, posing a great safety hazard to the patient. In actual clinical work, when a patient's condition is critical and needs to be transferred to the intensive care unit for rescue and treatment or from the emergency department to the operating room for emergency surgery, the electrocardiogram monitor is generally transported together. The currently commonly used method for transporting an electrocardiogram monitor is to directly place the electrocardiogram monitor beside the patient's pillow or even on the patient's body for transportation. Such a transportation method usually causes problems: the plane of the hospital bed is uneven, and the electrocardiogram monitor is not placed stably; because the electrocardiogram monitor cannot be fixed, when the transfer movement is relatively fast, the electrocardiogram monitor often topples over, which not only poses a risk of injury or infection to the patient, but also may accidentally trigger an unwanted function on the instrument, affecting the normal electrocardiogram monitoring process.

[0004] Therefore, those skilled in the art are committed to developing an electrocardiogram monitoring device for a medical transfer bed that can be fixedly integrated with the transfer bed and become an integral part of the transfer bed, which is very convenient and safe to use and store. Summary of the Invention

Among them, the power board, the main screen, the sensor module, the button module, and the recording and storage module are respectively connected to the main board. The electrocardiogram monitoring device for the medical transport bed further includes a drawer-shaped housing and a metal support frame.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which this invention belongs. The terms used in this specification in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items. In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the electrocardiogram monitoring device for a medical transfer bed described in this embodiment includes a drawer-shaped housing, a support frame, a main screen, buttons, a power board, a main board, a sensor connection cable, and a power and signal interface. Among them, the electrocardiogram monitoring device is integrally installed in the part of the medical transfer bed body near the head of the bed. The drawer-shaped housing has one or more handles, and the handles are embedded. When it is necessary to use it beside the transfer bed, the drawer-shaped housing can be pulled out by holding the handle, exposing the main screen and the sensor connection cable. The sensor connection cable is stored in a dedicated storage slot. The storage slot and the main screen are arranged side by side on the left and right inside the drawer-shaped housing. The buttons are located below the main screen near the handle. The buttons include a power on / off key and other function menu keys (not shown in the figure). The main screen is a color liquid crystal display with a resolution of 1024X768 or 1280X1024, and is equipped with a 10-point capacitive touch screen. The touch function and the buttons can be used in cooperation.

[0033] Inside the drawer-shaped housing, there is a metal support frame which roughly divides the internal space of the drawer-shaped housing into four parts: left, upper, middle, and lower. The left half of the support frame and the left half of the drawer-shaped housing together form a storage slot for the sensor connection cable. In the lower half of the storage slot, there are connection interfaces for the sensor cable and the main board. The connection interfaces include two blood pressure interfaces, one blood oxygen interface, one heart rate / pulse sensor interface, one respiratory sensor (carbon dioxide) interface, and one body temperature sensor interface. These interfaces are connected to the corresponding cables and sensors, and the cables and sensors pass through the first hole (not shown in the figure) at the bottom of the cable storage slot and then pass through the second hole (not shown in the figure) on the bed board inside the bed body to reach the affected area. When the transfer bed enters the transfer state, the drawer-shaped housing can be pushed into the bed body of the transfer bed. After being pushed in, the electrocardiogram monitoring device remains in the working state. On the outside of the drawer-shaped housing on the side away from the handle, there is a spring button. When the electrocardiogram monitoring device is pushed into the bed body of the transfer bed, this spring button collides with the corresponding limit part inside the bed body, and the spring button is pressed. After the main board detects that the spring button is pressed, it knows that the electrocardiogram monitoring device has been pushed into the bed body, so it switches the display content of the main screen to the secondary screen for display. The secondary screen is a color liquid crystal display with a resolution of 800X600 and does not have a touch function. The secondary screen is only used for display. The secondary screen is arranged on the outside of the opaque vault of the shielding cover and displays the corresponding content originally displayed on the main screen when the transfer bed is in the transfer (active or moving) state.

[0034] The right half of the metal support frame is divided into three layers: upper, middle, and lower. The upper right layer is used to accommodate the main screen of the electrocardiogram monitoring device. The middle right layer is used to install the power board, fan (not shown in the figure), and internal battery (optional, not shown in the figure) of the electrocardiogram monitoring device. The lower right layer is used to install the main board of the electrocardiogram monitoring device. One or more cable holes are provided between the respective internal sub-spaces divided by the metal support frame, and the rest is enclosed. Such a configuration is based on preventing mutual interference between the various components inside the electrocardiogram monitoring device and also preventing various electrical interferences brought by the outside of the electrocardiogram monitoring device (inside the medical structure) to a certain extent.

[0035] On the outside of the drawer-shaped housing on the side away from the handle, there are power and signal interfaces. The power interface here is connected to the power controller on the chassis of the transfer bed. When and only when the transfer bed is in the stationary (non-transfer) state, the power interface described in this embodiment can also be connected to the power outside the transfer bed. The power interface is internally connected to the main board and the internal battery respectively, and can supply power to the main board and charge the internal battery. The signal interfaces here include a wired network interface, a wireless network interface, and a secondary screen VGA signal interface.

[0036] The electrical functional block diagram of the electrocardiogram monitoring device for the medical transfer bed described in this embodiment is as Figure 5As shown in the figure, the electrocardiogram monitoring device includes a main board, a power board, a main screen and a secondary screen, a sensor module, a button module, and a recording and storage module. Among them, the power board, the main screen and the secondary screen, the sensor module, the button module, and the recording and storage module are respectively connected to the main board. An internal battery and a fan are connected to the power board. An alarm unit, a speaker, and an indicator light are respectively connected to the button module. The recording and storage module includes a USB interface and / or an SD card slot. The sensor module includes a blood pressure sensor, a blood oxygen sensor, an electrocardiogram sensor, a respiration (carbon dioxide) sensor, and a body temperature sensor, as well as corresponding groups of cables for connecting the corresponding sensors and a sensor interface board connected to the main board.

[0037] The electrocardiogram monitoring device for the medical transfer bed described in this embodiment detects and preprocesses the signals of physiological parameters through various preset sensors. The main board converts the biomedical signals into electrical signals, and performs preprocessing such as interference suppression, signal filtering, and amplification on the electrical signals output by the sensors in the signal processing system on the main board to obtain the output of the electrically processed signals. Then, through the data extraction and processing module, sampling, quantization are performed, and various parameters are calculated and analyzed. The results are compared with the set thresholds in the alarm device to determine whether they are within the safe monitoring range for supervision and alarm. The result data is stored in the external memory in real time through the recording device, so that medical staff can better view the changes in various previous parameters of this patient. The data output from the signal processing system can also be transmitted to the display device in real time, and the values of various parameters can be displayed in real time on the display device. If there are parameters that need to be monitored and controlled in real time, it can be achieved through the control system on the main board.

[0038] The electrocardiogram sensor is used to monitor the electrocardiogram signal. The electrocardiogram signal, from large to small, includes: input buffer, digital-to-analog conversion and lead definition, preamplification, high-pass filtering, analog-to-digital conversion, etc. After the lead collects the weak electrocardiogram signal, the electrocardiogram signal is collected through the lead. Using a thousands-of-volt isolated floating ground power supply and optoelectronic isolation, the electrocardiogram sensor is used alone. The communication adaptation circuit transmits the electrocardiogram signal to the microprocessor on the main board, and the microprocessor controls the working state of the electrocardiogram module through data instructions. After the electrocardiogram data is collected by the sensor, a series of tasks such as the display, storage, printing of the electrocardiogram, data management, waveform parameter calculation and analysis, and patient information management are completed. The electrocardiogram monitoring device for the medical transfer bed described in this embodiment can understand the changes in the human heart under active and quiet states through 7*24-hour continuous dynamic electrocardiogram recording and statistics, and present the relevant data in the form of an inspection report, with a higher detection rate of arrhythmia than conventional examinations, and can timely detect potential heart health hazards.

[0039] The electrocardiogram sensor module of the electrocardiogram monitoring device for the medical transfer bed described in this embodiment uses 12 leads to detect the electrical activity of the heart. A lead refers to a waveform diagram of the potential difference between two or more body surface parts of the human body changing with the cardiac cycle. Since the heart is three-dimensional, a lead waveform represents the electrical activity of the heart on a projection plane. Then, 12 leads will reflect the electrical activities of the heart on different projection planes from 12 directions, so that the lesions in different parts of the heart can be comprehensively judged. When measuring the electrocardiogram signal, the limb electrodes are placed on the wrists and ankles, and the electrodes for electrocardiogram monitoring are placed on the abdomen. The electrocardiogram monitoring device described in this embodiment can simultaneously monitor the waveforms of 12 leads and display 3 - 6 of them on the main screen, and extract cardiac parameters through waveform analysis, such as extracting the ST segment and capturing arrhythmia events. The electrocardiogram signal is an extremely weak electrical signal and is easily affected by external interference. The passband width of the amplifier in the measurement circuit of the electrocardiogram monitoring device described in this embodiment is relatively large, from 0.1 Hz to 75 Hz, which can ensure that the waveforms of each lead show more subtle structures.

[0040] The usage steps of the electrocardiogram monitoring device for the medical transfer bed described in this embodiment are as follows:

[0041] S1. Open the shielding cabin of the transfer bed, pull out the drawer-shaped outer shell to expose the electrocardiogram monitoring device panel;
