Description

Technical Field

[0001] The present invention belongs to the technical field of vital sign monitoring equipment, and specifically refers to a terminal non-invasive continuous vital sign monitoring equipment and a control system thereof. Background Art

[0002] In today's medical and health monitoring field, vital sign monitoring is a key means of evaluating human health. Traditional vital sign monitoring equipment has exposed a series of significant limitations in practical applications.

[0003] Most of the existing vital signs monitoring instruments have relatively single functions. For example, traditional blood pressure monitoring equipment only focuses on the collection of blood pressure data. Mercury sphygmomanometers rely on professionals to auscultate Korotkoff sounds to determine systolic and diastolic blood pressure. The operation is complicated and inconvenient to carry. Although electronic sphygmomanometers simplify the operation to a certain extent, they can only provide measurement results for a single indicator, blood pressure, and cannot take into account other important vital signs at the same time. Similarly, traditional blood oximeters only detect blood oxygen saturation, which is incapable of scenarios that require comprehensive health assessments based on a variety of vital signs data. If users want to fully understand their own blood pressure, blood oxygen and other key vital signs, they often need to be equipped with a variety of different monitoring devices, which not only increases costs, but is also extremely inconvenient to use.

[0004] Furthermore, traditional vital signs monitoring equipment has serious deficiencies in portability. Whether it is the large multi-parameter monitors commonly used in hospitals, or desktop blood pressure monitors and blood oximeters for home use, they are large in size and weight, making them inconvenient to carry and use at any time. For special groups of people who need to monitor their vital signs in real time, such as patients with chronic diseases who need to go out for activities, people who work outdoors for a long time, and athletes during training and competitions, it is not possible to conveniently use these devices for continuous monitoring in daily activity scenarios. This lack of portability greatly limits the scope and timeliness of vital signs monitoring, making it impossible for many potential health risks to be discovered and dealt with in the first place, which is not conducive to the comprehensive, dynamic and effective management of health conditions. Summary of the invention

[0005] In order to overcome the problems of the prior art, the present invention designs a fingertip non-invasive continuous vital signs monitoring device and a control system thereof, which can continuously monitor the fingertip blood pressure and blood oxygen of the human body and is easy to use.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a terminal non-invasive continuous vital signs monitoring device and its control system, comprising:

[0007] A housing, the front of which is provided with a screen, a switch button, a blood pressure measurement button and a blood oxygen measurement button, a controller is provided inside the housing, and the screen, the switch button, the blood pressure measurement button and the blood oxygen measurement button are all electrically connected to the controller;

[0008] A positioning cylinder is arranged on the top of the housing, and one side of the positioning cylinder is provided with an opening for inserting a finger;

[0009] An end cap is arranged at the end of the positioning tube, and when a finger is inserted into the positioning tube, the finger tip extends into the end cap;

[0010] Blood pressure measurement component, used to detect fingertip blood pressure;

[0011] Blood oxygen measurement component, used to detect blood oxygen.

[0012] Further, the blood pressure measurement assembly includes an air pump, an air pressure sensor and an air bag, the air bag is arranged in the positioning cylinder, the air bag is connected to the air pump and the air pressure sensor through a pipeline, the air pump is arranged in the housing, and the air pressure sensor and the air pump are both electrically connected to the controller;

[0013] Furthermore, the blood oxygen measurement component includes a light-emitting element and a photodetector, and the light-emitting element and the photodetector are respectively arranged on the upper and lower sides of the end cover, and the light-emitting element and the photodetector are both electrically connected to the controller.

[0014] Furthermore, an inner shell is embedded in the end cover, and openings are provided at both upper and lower ends of the inner shell to expose the light-emitting element and the photoelectric detector. The inner shell is elastic and is used to support and fix the fingertips.

[0015] Furthermore, the light emitting element includes a red light emitting diode and an infrared light emitting diode.

[0016] A control system, applied to the above-mentioned fingertip non-invasive continuous vital signs monitoring device, the controller is provided with a key detection module, a display control module, a blood pressure detection module and a blood oxygen detection module;

[0017] The button detection module is used to detect the pressed button; the display control module is used to control the screen display; the blood pressure detection module is used to detect blood pressure related vital signs, including pulse rate, systolic pressure and diastolic pressure; the blood oxygen detection module is used to detect the blood oxygen content and display it on the screen.

[0018] Further, the blood pressure detection module includes an air pump control unit, an air pressure detection unit, a pulse recognition unit, a systolic pressure recording unit and a diastolic pressure recording unit;

[0019] The air pump control unit is used to control the air pump to inflate and deflate the airbag;

[0020] The air pressure detection unit is used to obtain the air pressure change data measured by the air pressure sensor;

[0021] The pulse recognition unit uses a filtering algorithm to extract the pulse waveform from the air pressure change data, recognizes its parameters, calculates the pulse rate, and displays the pulse rate on the screen;

[0022] The airbag is inflated until the pulse cannot be identified and then begins to be deflated. During the deflation process, when the pulse identification unit identifies the pulse for the first time, the systolic pressure identification unit records the pressure value as the systolic pressure and displays it on the screen;

[0023] After the systolic pressure recognition unit recognizes and records the systolic pressure, the airbag continues to deflate until the pulse recognition unit cannot recognize the pulse, and the diastolic pressure recognition unit records the pressure value at this time as the diastolic pressure and displays it on the screen.

[0024] Furthermore, it also includes a vital sign monitoring alarm module, which continuously monitors pulse rate and blood oxygen, regularly detects blood pressure, and stores data, and issues an alarm when an abnormality is detected.

[0026] Furthermore, it also includes an operation guidance module, which controls the screen to display the corresponding operation guidance text when the blood pressure measurement button or the blood oxygen measurement button is pressed.

[0027] The beneficial effects of the fingertip non-invasive continuous vital sign monitoring device and its control system of the present invention are as follows: multi-index detection can not only detect fingertip blood pressure (including systolic pressure, diastolic pressure and pulse rate), but also detect blood oxygen content. One device can obtain multiple key vital sign indicators at the same time, reducing the trouble of using multiple different detection devices, making it convenient for medical staff or users to have a more comprehensive understanding of the physical condition, and helping to more accurately evaluate and diagnose the health status; equipped with a vital sign monitoring alarm module, it can continuously monitor the pulse rate, blood oxygen, and regularly detect blood pressure. Once abnormal conditions are detected in these vital signs, an alarm will be issued in time, allowing medical staff to know the changes in the patient's condition in the first time, or reminding the user to take corresponding measures (such as medical treatment, etc.) in time, which is of great significance for protecting life, health and safety; one end of the shell A data line interface is provided to facilitate the export of data monitored and stored by the device, which is conducive to the subsequent data analysis, archiving and comparison of data in different time periods by medical staff, so as to better track the development of the disease and evaluate the treatment effect; a power-saving module is provided to determine whether the finger is pulled out by detecting the change of light intensity data through a photoelectric detector. When the pull-out time exceeds the preset time, the device is automatically shut down, avoiding the long-term meaningless standby power consumption of the device, extending the overall battery life of the device, and being more energy-saving and environmentally friendly, which meets the use requirements of modern equipment; the operation guidance module can control the screen to display the corresponding operation guidance text when the blood pressure measurement button or the blood oxygen measurement button is pressed, providing clear guidance for users who are using the device for the first time or are not familiar with the operation process, ensuring that each test can be carried out accurately, and improving the accuracy and reliability of the test results.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-2 As shown, the present invention is a fingertip non-invasive continuous vital signs monitoring device, comprising:

[0034] A housing 1, on the front of which a screen 11, a switch button 12, a blood pressure measurement button 13 and a blood oxygen measurement button 14 are arranged, and a controller 2 is arranged inside the housing 1, and the screen 11, the switch button 12, the blood pressure measurement button 13 and the blood oxygen measurement button 14 are all electrically connected to the controller 2;

[0035] A positioning tube 3 is arranged on the top of the housing 1, and one side of the positioning tube 3 is provided with an opening for inserting a finger;

[0036] An end cap 4 is arranged at the end of the positioning tube 3. When a finger is inserted into the positioning tube 3, the fingertip extends into the end cap 4;

[0037] A blood pressure measuring component 5, used for detecting fingertip blood pressure;

[0038] The blood oxygen measurement component 6 is used to detect blood oxygen.

[0039] Further, the blood pressure measurement assembly 5 includes an air pump 51, an air pressure sensor 52 and an air bag 53, the air bag 53 is arranged in the positioning cylinder 3, the air bag 53 is connected to the air pump 51 and the air pressure sensor 52 through a pipeline, the air pump 51 is arranged in the housing 1, and the air pressure sensor 52 and the air pump 51 are both electrically connected to the controller 2;

[0040] Furthermore, the blood oxygen measurement component 6 includes a light emitting element 61 and a photodetector 62 , and the light emitting element 61 and the photodetector 62 are respectively arranged on the upper and lower sides of the end cover 4 , and the light emitting element 61 and the photodetector 62 are both electrically connected to the controller 2 .

[0041] Furthermore, an inner shell 41 is embedded in the end cap 4, and openings are provided at both upper and lower ends of the inner shell 41 to expose the light emitting element 61 and the photodetector 62. The inner shell 41 is elastic and is used to support and fix the fingertips. The inner shell 41 fits the fingertips to prevent the movement of the fingers from affecting the detection results, and is elastic and can adapt to different finger thicknesses.

[0042] Furthermore, the light emitting element 61 includes a red light emitting diode and an infrared light emitting diode. The LEDs include two different wavelengths, generally a red light wavelength of about 660nm and an infrared light wavelength of about 940nm, because the oxygenated hemoglobin HbO2 and reduced hemoglobin Hb in the blood have different absorption characteristics for the two lights, oxygenated hemoglobin absorbs infrared light more strongly and red light less weakly; reduced hemoglobin is the opposite, by alternately emitting the two lights, the degree of absorption of the two lights can be measured, and then the blood oxygen saturation can be calculated.

[0043] like Figure 3 As shown, a control system is applied to the above-mentioned fingertip non-invasive continuous vital signs monitoring device, and the controller 2 is provided with a key detection module 21, a display control module 22, a blood pressure detection module 23 and a blood oxygen detection module 24;

[0044] The button detection module 21 is used to detect the pressed button; the display control module 22 is used to control the display image of the screen 11; the blood pressure detection module 23 is used to detect blood pressure related vital signs, including pulse rate, systolic pressure and diastolic pressure; the blood oxygen detection module 24 is used to detect the blood oxygen content and display it on the screen 11.

[0045] Further, the blood pressure detection module 23 includes an air pump control unit 231, an air pressure detection unit 232, a pulse recognition unit 233, a systolic pressure recording unit 234 and a diastolic pressure recording unit 235;

[0046] The air pump control unit 231 is used to control the air pump 51 to inflate and deflate the airbag 53;

[0047] The air pressure detection unit 232 is used to obtain the air pressure change data measured by the air pressure sensor 52;

[0048] The pulse recognition unit 233 uses a filtering algorithm to extract the pulse waveform from the air pressure change data and recognizes its parameters to calculate the pulse rate, and displays the pulse rate on the screen 11;

[0049] The airbag 53 is inflated until the pulse cannot be identified and then begins to deflate. During the deflation process, when the pulse identification unit 233 identifies the pulse for the first time, the systolic pressure identification unit 234 records the pressure value as systolic pressure and displays it on the screen 11.

[0050] After the systolic pressure recognition unit 234 recognizes and records the systolic pressure, the airbag continues to deflate until the pulse recognition unit 233 cannot recognize the pulse, and the diastolic pressure recognition unit 235 records the pressure value at this time as the diastolic pressure and displays it on the screen 11.

[0051] Furthermore, it also includes a vital sign monitoring alarm module 25, which continuously monitors pulse rate and blood oxygen, regularly detects blood pressure, and stores data, and issues an alarm when an abnormality is detected. A data line interface 15 is provided at one end of the shell 1 to export data, and a speaker 7 is provided inside the shell 1.

[0052] Furthermore, it also includes a power saving module 28. The power saving module 26 measures the change of light intensity data through the photoelectric detector 52, determines whether the finger is pulled out, and automatically shuts down the device after the finger is pulled out for more than a preset time.

[0053] Furthermore, an operation guidance module 27 is included, and pressing the blood pressure measurement button 13 or the blood oxygen measurement button 14 controls the screen 11 to display a corresponding operation guidance text.

[0054] The beneficial effects of the fingertip non-invasive continuous vital sign monitoring device and its control system of the present invention are as follows: multi-index detection can not only detect fingertip blood pressure (including systolic pressure, diastolic pressure and pulse rate), but also detect blood oxygen content. One device can obtain multiple key vital sign indicators at the same time, reducing the trouble of using multiple different detection devices, making it convenient for medical staff or users to have a more comprehensive understanding of the physical condition, and helping to more accurately evaluate and diagnose the health status; equipped with a vital sign monitoring alarm module, it can continuously monitor the pulse rate, blood oxygen, and regularly detect blood pressure. Once abnormal conditions are detected in these vital signs, an alarm will be issued in time, allowing medical staff to know the changes in the patient's condition in the first time, or reminding the user to take corresponding measures (such as medical treatment, etc.) in time, which is of great significance for protecting life, health and safety; one end of the shell A data line interface is provided to facilitate the export of data monitored and stored by the device, which is conducive to the subsequent data analysis, archiving and comparison of data in different time periods by medical staff, so as to better track the development of the disease and evaluate the treatment effect; a power-saving module is provided to determine whether the finger is pulled out by detecting the change of light intensity data through a photoelectric detector. When the pull-out time exceeds the preset time, the device is automatically shut down, avoiding the long-term meaningless standby power consumption of the device, extending the overall battery life of the device, and being more energy-saving and environmentally friendly, which meets the use requirements of modern equipment; the operation guidance module can control the screen to display the corresponding operation guidance text when the blood pressure measurement button or the blood oxygen measurement button is pressed, providing clear guidance for users who are using the device for the first time or are not familiar with the operation process, ensuring that each test can be carried out accurately, and improving the accuracy and reliability of the test results.

[0055] The present invention and its embodiments are described above, which is not restrictive. What is shown in the accompanying drawings is only one of the embodiments of the present invention, and the actual content is not limited to this. In short, if ordinary technicians in this field are inspired by it and do not deviate from the purpose of the invention, they can creatively design structural methods and embodiments similar to the technical scheme, which should all fall within the scope of protection of the present invention.
