Description

Technical Field

[0001] The invention relates to the technical field of nursing monitoring equipment, in particular to a vital sign monitor. Background Art

[0002] A vital signs monitor is a device used to monitor human vital signs. It is usually used in medical institutions, emergency scenes, home care and other occasions. Its main functions include measuring body temperature, heart rate, respiratory rate and other indicators. It can help medical staff or guardians to monitor the patient's vital signs in a timely manner, understand the patient's health status, detect abnormal conditions in time and take appropriate treatment measures.

[0003] In recent years, with the increase of people's life and work pressure and the arrival of the aging of the social population, various sub-health and chronic diseases have occurred frequently, and even sudden cardiac death without obvious symptoms has occurred. Researchers have found that most sudden cardiac deaths are caused by ventricular tachyarrhythmias, and often occur at night. In addition, researchers have also found that sleep apnea syndrome (SAS) is often complicated by arrhythmias and may cause angina pectoris, myocardial infarction, etc. In this regard, some vital signs monitoring devices have been developed to monitor the user's heart and respiratory function, mainly wearable vital signs monitoring devices and non-wearable vital signs monitoring devices. Wearable vital signs monitoring devices need to be worn for a long time to collect and monitor vital signs data. This process is likely to cause discomfort to the user, which will reduce the quality of data collection and monitoring while affecting the user's sleep and rest; for non-wearable vital signs monitoring devices such as monitoring mattresses or monitoring pads placed on mattresses, the monitoring sensing components of the monitoring mattresses and monitoring pads are fixedly arranged therein. During sleep, the monitoring is easily interrupted for a long time due to changes in sleeping posture. The movable monitoring pad will be offset due to changes in sleeping posture, further reducing the subsequent monitoring quality.

[0004] Chinese Patent 202110497134.9 discloses an intelligent multifunctional intra-hospital transfer bed, comprising a bed frame and a bedside, wherein a storage rack is fixedly arranged under the bed frame, and a display screen is arranged on the bedside; a translation plate is placed on the bed frame, and a mattress is placed on the translation plate, and the mattress is communicatively connected to the display screen; the mattress is an ECG monitoring mattress, comprising a mattress body, a heating wire and a laser light arranged in the mattress body, a pressure monitoring belt, and a control processor, the pressure monitoring belt collects circuit signals, the control processor converts the circuit signals into digital signals, monitors the patient's respiratory rate, heart rate, blood pressure, blood oxygen and other vital signs, the control processor transmits the digital signal data to the display screen, and the display screen displays the content monitored by the ECG monitoring mattress to remind abnormal vital signs. Chinese patent CN202010168668.2 discloses a vibration sign monitor, a vital sign monitoring system and method, wherein the vibration sign monitor includes: a piezoelectric film sensor for collecting simulated vibration sign signals of the monitored person; a controller connected to the piezoelectric film sensor, for performing analog-to-digital conversion on the simulated vibration sign signals to obtain vibration sign data, and determining whether the parsing and display terminal is online, and if so, sending the vibration sign data to the parsing and display terminal, and if not, sending the vibration sign data to the original data storage and parsing server. However, the vital sign monitor in the prior art, whose monitoring component is fixed during use, is prone to be separated from the contact point between the monitoring component and the monitored person for a long time due to the change of sleeping posture, resulting in monitoring interruption, thereby reducing the monitoring quality. Summary of the invention

[0005] The purpose of the present invention is to overcome the problem that the existing vital signs monitor is easily separated from the contact point between the monitoring component and the monitored person for a long time due to changes in sleeping posture, causing monitoring interruption and thus reducing the monitoring quality. The present invention provides a vital signs monitor that can be adapted to changes in the sleeping posture of the monitored person.

[0022] The technical scheme of the present invention is clearly and completely described below in conjunction with the specific embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1 A kind of Figure 1-7 The present invention provides a vital sign monitor, comprising a host 1 and a monitoring bag 2, wherein the monitoring bag 2 can be arranged between a mattress and a bed sheet, and the four corners of the monitoring bag 2 are adhered to the mattress by means of tape or Velcro, wherein a movable monitor 3 is arranged in the monitoring bag 2, and the monitor 3 is provided with a wire connected to the host 1; the present application performs signal feedback through the monitor 3, and then the vital sign index of the heart rate, respiratory rate and body temperature is obtained through analysis and calculation by the host 1, the present application host 1 also includes a display component, an alarm component and a network module, and the host 1 can store and analyze the original data, and can be used to receive and store various data from the monitor of the present application for monitoring vital signs, and compare and analyze the collected vital sign data with the original stored data, the network module of the present application compares the received respiratory and heart rate monitoring data with the preset data range of various indicators, if the received respiratory and heart rate monitoring data are within the preset data range, the corresponding vital sign data is monitored, if the received respiratory and heart rate monitoring data are not within the preset data range, the network module issues an instruction to drive the alarm component to make a prompt process.

[0024] The inner bottom of the monitoring bag 2 is made of smooth material, and the upper layer of the monitoring bag 2 is made of smooth film material to reduce the contact friction between it and the monitoring bag 2, so as to improve the sliding of the monitor 3 of the present application in the monitoring bag 2; the monitor 3 is provided with a vital sign monitoring sensor 4, and the outer wall of the monitor 3 is designed to be smooth, which further reduces the contact friction between the monitor 3 and the monitoring bag 2, so that it can slide freely during the process of the pull rope 5 being retracted and released by the pull rope motor; four pull ropes 5 are provided on the four corners of the monitoring bag 2, and the pull ropes 5 are respectively adhered to the mattress by tape or Velcro to fix it, such as Figure 7 The pull rope 5 comprises a soft inner core rope body 51 and a conduit 52. The inner core rope body 51 is in smooth contact with the inner wall of the conduit 52 and lubricating oil is provided between the inner core rope body 51 and the conduit 52. The diameter of the conduit 52 of the pull rope 5 is 5-10 mm, and the inner core rope body 51 is made of flexible steel rope. The pull rope 5 of the present application is arranged between the mattress and the bed sheet. There is no obvious discomfort when the monitored person lies down, and it will not cause discomfort to the back due to lying for a long time. One end of the pull rope 5 is connected to the four corners of the monitor 3, and the other end is connected to the host 1, that is, one end of the inner core rope body 51 of the pull rope 5 is connected to the four corners of the monitor 3, and the other end is connected to the host 1. Four pull wire motors and electronic devices for monitoring vital signs are provided in the host 1. The host 1 is equipped with a driving power supply and a frequency converter corresponding to the pull wire motor. The operating parameters of the pull wire motor of the present application are obtained through a preset program before leaving the factory. During the operation process The monitor 3 can be adjusted in the monitoring bag 2 by retracting and releasing the pull rope 5 through coordination between the pull wire motors, so that it can meet the multi-directional search for the monitoring target, that is, in the process of searching for the monitoring target, the pull wire motor retracts half a circle and pauses for 3-5s. After the monitor 3 finds the area where the monitoring target is located, the pull wire motor fine-tunes the monitor 3 by retracting and releasing the pull wire 5. Under normal circumstances, the monitor 3 is fine-tuned to be as close as possible to the bottom of the heart of the monitored person for monitoring. Due to changes in the sleeping posture of the monitored person, such as sleeping on the side with the heart side away from the mattress, the monitor 3 is fine-tuned to be in contact with the body of the monitored person for monitoring. This application uses a small pull wire motor to retract and release the pull wire 5; the electronic device for vital signs monitoring can obtain the vital signs monitoring value according to the information fed back by the vital signs monitoring sensor 4; the host 1 adjusts the position of the monitor 3 in the monitoring bag 2 by controlling the four pull wire motors.

[0025] like Figure 6The vital sign monitoring sensor 4 described in the present application includes a pressure sensor 41, a vibration sensor 42, a humidity sensor 43 and multiple temperature sensors 44. The pressure sensor 41, the vibration sensor 42 and the humidity sensor 43 are arranged on the monitor 3 at equal intervals and are installed alternately with the temperature sensor 44; and the monitor 3 is initially arranged below the chest position of the monitored person after the monitored person lies flat (set according to the average height of the monitored person). The present application monitors the respiratory rate sign data of the monitored person through the vibration sensor 42, and collects the corresponding simulated vibration sign signal of the monitored person. Under the data monitoring and analysis of the temperature sensor 44, the vibration sensor 42 of the present application can also perform waveform separation on the vibration sign data in combination with the pressure sensor 41 to determine whether the separated waveform has a periodic feature, and can determine whether the monitored person has left the bed or changed his sleeping posture, thereby improving the data monitoring quality; if so, it is determined that the vibration sign data is obtained when the monitored person is in bed, otherwise it is determined that the vibration feature data is obtained when the monitored person is out of bed.

[0026] In the monitoring process of the present application, when the sleeping posture of the monitored person changes, the data fed back by the pressure sensor 41 and the vibration sensor 42 set on the monitor 3 are analyzed and processed by the host 1, and the corresponding pull-wire motor is driven to retract and release the pull rope 5 to drive the monitor 3 to search for the monitoring target in the monitoring bag 2, and then the temperature sensor 44 of the monitoring bag 2 is used in combination with the vibration sensor 42. If there is no obvious change in temperature after the search, the information is fed back to the host 1, and a command is issued through the network module of the host 1 to drive the alarm component to make a prompt processing; that is, the host 1 of the present application calculates the temperature difference based on the temperature feedback information of the temperature sensor 44, and then drives the corresponding pull-wire motor to retract and release the pull rope 5 based on the feedback information of the pressure sensor 41 and the vibration sensor 42 combined with the temperature difference, so that the monitor 3 moves to a position close to the position below the heart of the monitored person, so as to monitor the corresponding vital signs of the monitored person.

[0027] Embodiment 2 On the basis of the above embodiments, the applicant of the present application referred to the "Chinese Adult Body Size Standard and Intelligent Management System", "American Society of Human Biology Anthropometrics Manual" and the data from the "Chinese Body Shape Survey" (compiled by Sun Baochen, Zhu Qiqun, etc., published in 2010), and made a reference to the average body size of the adult population (including the elderly) in China, and found that the average body width of adult males is 42-48cm, and the average body width of adult females is 37-43cm. Therefore, the present application provides a monitoring bag 2 on the mattress relative to the upper body of the monitored person, such as Figure 2-4It is stated that, through experimental analysis by the applicant, it is concluded that when the monitored person's upper body lies on the mattress in the area where the monitoring bag 2 is located, and the length of the monitoring bag 2 described in this application is 2 / 5-3 / 5 of the mattress length, and the width of the monitoring bag 2 is 1 / 2-2 / 3 of the mattress width, that is, the width of the monitoring bag 2 is greater than the body width of the monitored person, so that the data monitored in the monitoring bag 2 can be maintained in a stable fluctuation range and can adapt to changes in the monitored person's sleeping posture; the experiment found that when the width of the monitoring bag 2 is greater than 2 / 3 of the mattress width, and the length of the monitoring bag 2 is 2 / 5-3 / 5 of the mattress length, after the monitored person lies down, the data monitored in the monitoring bag 2 can be maintained in a stable fluctuation range, and can also be applicable to the monitored person. Monitor changes in a person's sleeping posture; experiments have found that when the width of the monitoring bag 2 is less than 1 / 2 of the width of the mattress and the length of the monitoring bag 2 is 2 / 5-3 / 5 of the length of the mattress, after the monitored person lies down, the data monitored in the monitoring bag 2 can be maintained in a stable fluctuation range, but as the monitored person's sleeping posture changes, the monitoring data is prone to loss and data false alarms; therefore, when the length of the monitoring bag 2 described in this application is 2 / 5-3 / 5 of the length of the mattress and the width of the monitoring bag 2 is 1 / 2-2 / 3 of the width of the mattress, after the monitored person lies down, the data monitored in the monitoring bag 2 can be maintained in a stable fluctuation range, and can adapt to changes in the monitored person's sleeping posture, thereby improving its practical performance.

[0028] Embodiment 3 On the basis of the above embodiments, in order to improve the ability of the monitor 3 to slide freely in the monitoring bag 2 when the pull rope 5 is retracted and released by the pull rope motor, and reduce the contact friction between the monitor 3 and the monitoring bag 2, the monitor 3 described in the present application is elliptical in shape, and the bottom of the inner side of the monitoring bag 2 is paved with sand or lubricant (not shown in the figure) for contacting the bottom of the monitor 3. Through comparison of simulated monitoring tests, it is found that the wear at the connection between the pull rope 5 and the monitor 3 of this embodiment is reduced by 3%; and the energy consumption of the pull rope motor is reduced by 2%.

[0029] Embodiment 4 Based on the above embodiments, Figure 3-4As described, in order to improve the monitoring device 3, the present embodiment is provided with micro electromagnets at the midline positions of the four sides of the monitoring bag 2. The circumference of the monitor 3 of the present application is coated with iron sheets or provided with iron blocks (not shown in the figure), so that after the monitor 3 moves to the corresponding area, the micro electromagnet can be charged so that it is combined with the micro electromagnet under the action of the magnetic attraction of the micro electromagnet, and the micro electromagnet can be discharged so that it is separated from the micro electromagnet, so that the monitor 3 of the present application can reach the area of ​​the position of the midline of each side of the monitoring bag 2, thereby increasing its search for the monitored person and its contact area with the monitored person. Through experimental comparison, it is found that four pull ropes 5 are provided on the four corners of the monitoring bag 2 described in the present application, and one end of the pull rope 5 is connected to the four corners of the monitor 3. The monitor 3 adjusts the position of the monitor 3 in the monitoring bag 2 by retracting and releasing the pull rope 5 through a pull rope motor, so that the moving area is relatively adjusted relative to the circular monitoring bag 2 by three or four pull ropes 5 set for position adjustment and the moving area is relatively adjusted relative to the four pull ropes 5 set for position adjustment at the midline positions of the four sides of the monitoring bag 2. The moving areas are large, that is, the moving area of ​​the monitor 3 adjusted in the monitoring bag 2 of the present application is greater than the moving area of ​​the monitor 3 adjusted by the four pull ropes 5 set on the circular monitoring bag 2> the moving area of ​​the monitor 3 adjusted by the four pull ropes 5 set on the center lines of the four sides of the monitoring bag 2> the moving area of ​​the monitor 3 adjusted by the three pull ropes 5 set on the circular monitoring bag 2; after the present application searches the corresponding area in vain by retracting and releasing the pull rope 5 by the pull rope motor, and cooperates with the charging and discharging of the micro electromagnet to enable the monitor 3 of the present application to move to the area where the four center lines of the monitoring bag 2 are located, thereby increasing the moving area of ​​the monitor 3 of the present application in the monitoring bag 2, so as to improve the accuracy of the data transmission of the monitor 3, and avoid the data misreporting caused by the fixed moving area of ​​the monitor 3 and the failure to search for the monitored person. After experimental comparison, the use of the pull rope motor of the present application in conjunction with the micro electromagnet can increase the moving area of ​​the monitor 3 of the present application in the monitoring bag 2, and its search monitoring data transmission accuracy is improved by 5%.

[0030] Control group 1 The difference between this control group and the above-mentioned embodiment is that a wide-mouthed receiving groove is arranged at the midline position of the four sides of the monitoring bag corresponding to the monitor, and an air pipe is arranged in the receiving groove. The air pipe is connected to the high-pressure air pump through a pipeline. When the monitor moves to the area where each side is located, the pull-wire motor releases the rope, and the air pipe ventilation on the opposite side of the area where the monitor is located pushes the monitor so that it can be placed on each side of the monitoring bag, thereby increasing the search area for the monitoring target. Through experimental comparison of the monitor moving to the midline position area of ​​the four sides of the monitoring bag, it is concluded that the comprehensive energy consumption required for the pull-wire motor combined with the high-pressure air pump in the control group one to drive the monitor to move in the monitoring bag is increased by 8% compared with the comprehensive energy consumption required for the pull-wire motor combined with the micro electromagnet in the embodiment four of the present application.

[0031] Control group 2 This control group uses a vital sign monitoring mattress in the prior art, and its structure includes a mattress body, a heating wire and a laser light arranged in the mattress body, a pressure monitoring belt, and a control processor. The pressure monitoring belt collects circuit signals, and the control processor converts the circuit signals into digital signals to monitor the patient's respiratory rate, heart rate, blood pressure, blood oxygen and other vital signs. The control processor transmits the digital signal data to the display screen, and the display screen displays the content monitored by the ECG monitoring mattress to remind abnormal vital signs. The monitoring components of the monitoring mattress provided in the control group 2 cannot be used to make adjustments automatically due to changes in the sleeping posture of the monitored person, which is easy to reduce its monitoring quality. After experimental comparison, it is found that the false alarm rate of its monitoring data is improved by 8% compared with the vital sign monitor improved in this application.

[0032] Control group three The control group uses a vital signs monitoring belt in the prior art, such as a certain brand of vital signs (sleep) monitor, in which the monitor is placed between the bed sheet and the mattress, below the chest when the person lies down, and the monitoring component is fixed in the monitor, and the monitor is placed between the bed sheet and the mattress, and is fixed by the pressure of the monitored person lying flat. It is easy to move when the monitored person changes his sleeping posture and exerts great force, affecting the reliability of the monitoring data. Through experimental comparison, it is found that the false alarm rate of its monitoring data is improved by 12% compared with the vital signs monitor improved in this application.

[0033] To summarize, the present application uses a pull-wire motor in combination with a host 1 and a monitor 3, so that the vital signs monitor 4 provided by the present application can make automatic adjustments after the sleeping posture of the monitored person changes. The vital signs monitoring sensor 4 arranged on the monitor 3 feeds back the monitoring signal, and then the host 1 analyzes and calculates the vital signs index of the heart rate, respiratory rate and body temperature, thereby improving the data monitoring quality of the life characteristics monitor of the present application for the monitored person, so as to solve the problem that the existing vital signs monitor is easily separated from the contact point between the monitoring component and the monitored person for a long time due to changes in sleeping posture, resulting in monitoring interruption, thereby reducing the monitoring quality.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
