Description
Technical Field
The invention relates to the technical field of infant intelligent monitoring, in particular to a mattress with an infant state monitoring system.
Background
For infants who do not have the ability to express themselves or environmental influences accurately, the guardian usually knows the emotions, needs and health of the infant by means of crying or limb movements.
The reasons causing the infant crying may be pathology, hunger and thirst, tiredness and sleepiness, discomfort, flatulence, desire to fight, pain, fear, irritability, bed-wetting or desire to go to the toilet, etc., the guardian of the infant usually checks the infant crying reasons one by one, although a certain range can be reduced, a lot of time is wasted in the process of detecting the crying reasons, and the actual demand state of the infant crying cannot be rapidly and scientifically acquired every time. The above reasons are expressed in the form of uniform crying, and the actual need for crying of the infant cannot be accurately and effectively determined due to the fact that the guardian, especially young parents, are extremely lack of long-term care experience. Moreover, if the infant is cared by the elderly who are high in the ages at home, the elderly do not have enough heart and energy to care for the infant, the health condition of the infant is judged by the feelings and experiences of the elderly, and the actual needs and the actual health condition of the monitored infant are difficult to accurately know.
The prior art infant monitoring auxiliary systems usually reflect the actual demand state of the infant crying for a specific reason, and little attention is paid to that the crying in the actual life is often driven by a plurality of reasons. For example, infants may initially cry as a result of hunger thirst, and after a period of time without human attention and timely handling, infants feel tired and womb to cry. Therefore, in a similar situation, no matter which reason is displayed, even if the reason is accurate (such as hunger and thirst or tiredness and sleepiness), the baby still cries after the guardian treats the reason according to the provided single reason, the condition that the baby cries due to multiple reasons cannot be solved, and the nursing effect is affected.
Chinese patent (publication No. CN103489282B) discloses a baby monitor capable of identifying baby crying, which comprises a main control module, a baby crying identification module and a short message sending module, wherein the baby crying identification module collects voice information in the surrounding environment in real time and processes the voice information, distinguishes the crying of the baby from other sounds in the environment and sends the crying information of the baby to the main control module; the main control module sends an alarm short message to a preset mobile phone number. Although the baby monitor provided in the system and the method of the patent can monitor whether the baby cries or not within 24 hours, and automatically send alarm information to the guardian when the baby cries, the deficiency of manual supervision can be effectively made up; it can replace part of manual labor, and reduce the cost of manual supervision. However, the patent does not solve the problem of how to accurately distinguish and provide better monitoring auxiliary effect under the condition that crying is caused by a plurality of reasons, and the frequent alarming information caused by frequent crying of the baby cannot achieve the beneficial effects of making up for the manual supervision and reducing the cost. Therefore, there is a need for a mattress with an infant status monitoring system that can provide more accurate actual needs of the guardian for the infant according to the environment of the infant and the physical sign information thereof under the environment condition, so as to achieve a better monitoring assistance effect.

Example 2
This embodiment is a further improvement of embodiment 1, and repeated contents are not described again.
Preferably, the mattress is further provided with an auxiliary device 8 communicatively coupled with the cloud server 7. The auxiliary device 8 may be a voice player, a video player or a hypnotic device, which can be used to aid the infant in sleeping when it is in a shallow or awake state to avoid the infant from further crying when it is in an awake state at night. For example, the auxiliary device may play a voice message recorded by the mother in advance or a video such as an animation to distract the baby and gradually let the baby go to sleep again. The aid 8 may also be a device capable of stimulating the infant with sound, light or motion. For example, the aid device may be provided with various toys, which during the day the infant is awake can attract the attention of the infant through the various toys, thereby avoiding crying caused by, for example, being boring alone.
Preferably, the auxiliary device 8 is configured to be in an operating mode that is activated or deactivated by the cloud server 7. Specifically, the physical sign information acquisition device 1 can transmit acquired data information of the infant, such as heartbeat, limb action amplitude, respiratory frequency, body temperature and the like, to the cloud server 7, so that the cloud server can monitor the sleep state of the infant. For example, the sleep stage can be divided into three basic stages, the first stage being a light sleep stage where the infant has limbs that move more frequently and can be easily awakened. The second phase is a transition phase in which the infant relaxes further in muscles to reduce limb movement and the heart rate and body temperature are both further reduced. The third stage is a deep sleep stage, the heart rate and body temperature of the infant are in a continuous steady state, and the frequency of limb movements is minimized. When the infant is in a light sleep stage, the infant is easily in a waking state due to interference of the external environment, and further crying is induced.
Preferably, the cloud server 7 is configured to determine the nursing time of the infant according to the following steps:
s1: an initial care time profile for the infant is established based on the physiological and/or pathological needs of the infant. Preferably, the physiological need may be a need for lactation of the infant and the pathological need may be a need for feeding or dressing change of the infant. Physiological and pathological requirements have the property that they must be met by the time they occur, otherwise they will have a significant impact on the infant. The physiological requirement or the pathological requirement can be input and designated by a third party, or can be determined after autonomous learning is carried out by the cloud server according to historical data. For example, the third party may be a nurse, a doctor or a parent thereof who is nursing a baby, who is familiar with the physiological needs and pathological needs of the baby, and thus, an initial nursing time history of the baby, i.e., how often the baby is cared for, may be established in the server in a specified manner. The cloud server may also autonomously determine a preliminary nursing time profile by, for example, a third party for the baby's daily nursing time. The primary care time history is a schedule at which the physiological or pathological needs of the infant are met.
S2: first time T for determining that infant is in waking state based on infant sign information acquired by sign information acquisition device1At a first time T1The second time T closest to the primary nursing time calendar2In case the difference between each other exceeds a first set threshold, the auxiliary device 8 is activated to turn on to avoid the baby crying, and the need information analysis module 701 determines at least two first theoretical need information of the baby based on the vital sign information and the environmental information. In particular, a first time T1The second time T closest to the primary nursing time calendar2A difference between each other exceeding the first set threshold indicates that the infant is in an abnormally awake state, which has an early wake-up that is most likely due to external environmental factors or its own factors. For example, the infant is awake at 4 am, and the second time T of the preliminary nursing time history, which is the most recent nursing time or dressing change time, for example2A first set threshold of 1 hour at 6 am indicates that the infant is awake too early, which in the present situation may not be due to hunger but may be due to other factors such as bed wetting or external noise. To avoid crying of the infant due to premature arousal, the supplementThe aid 8 can be opened in advance to soothe the infant. Meanwhile, the environmental sensor 5 and the physical sign information acquisition device 1 transmit the environmental information and the physical sign information acquired by the environmental sensor and the physical sign information acquisition device to the demand information analysis module 701. The need information analysis module 701 is capable of determining a reason for the infant to suddenly wake and determining at least two first theoretical need information based on the reason. For example, the transition from a sleep state to an awake state of an infant may be caused by a combination of factors such as thunder, external noise, bed wetting, etc. The first theoretical requirement information may include noise abatement and diaper replacement.
S3: when the auxiliary device 8 is turned on to suppress crying of the infant, the demand information analysis module 701 can determine the tendency of the infant to crying based on at least the information such as the infant sign information, the limb movement information, the facial expression, the eye attention and the like acquired by the sign information acquisition device, wherein the configuration update module 702 determines the execution time T at which the first theoretical demand information is satisfied when the infant does not crying3Move to the second time T2The method performs configuration updating on the preliminary care time history table. The opening of the aid 8 when the infant is awake can attenuate the effects on the infant caused by factors such as noise, irritability, convulsions, bed wetting, etc. I.e. a part of the first theoretical need information of the baby, is eliminated by the aid 8. During the opening of the auxiliary device 8, it can be determined whether the auxiliary device has an effect on the baby by analyzing the physical sign information of the baby. For example, when the auxiliary device is turned on to play an animation video or a pre-recorded audio of the mother, if the baby is attracted to the infant, the breathing frequency and the body movement frequency are reduced, the eye attention is focused, and the facial expression is changed from being irritated. By monitoring the state of the infant in the waking state in real time, the condition that the first theoretical requirement information is met can be effectively found, and the first theoretical requirement information of the infant, such as changing a diaper, can be met in a delayed manner when the infant does not have a crying trend. At this time, the execution time T of the first theoretical requirement information3May be delayed to the nearest secondTime T2. Preferably, the execution time T of each piece of first theoretical requirement information3All can independently set limit execution time T4. Limit execution time T4The information indicative of the first theoretical need must be performed before that moment, otherwise it will have a significant impact on the infant. For example, the limit execution time T of the baby bed-wetting4It can be set that within 3 hours from the time of occurrence, treatment for more than 3 hours will cause the infant to feel extremely uncomfortable to cry and affect the skin of the infant's buttocks. Preferably, the limit execution time T4A setting mode configured to be manually configurable by a third party. The auxiliary device can effectively inhibit the baby from crying, and avoid the influence of the frequent crying on the baby. Meanwhile, not all the first theoretical requirement information needs to be executed and satisfied at the fastest speed, and the combination of the execution time of the first theoretical requirement information and the nursing time in the preliminary nursing time history table can effectively reduce the nursing frequency of the third party to the baby and greatly reduce the labor intensity of the third party.
Preferably, in the case where each piece of the first theoretical demand information is individually configured with the limit execution time and the difference between the limit execution time and the nearest third time is smaller than the second set threshold, the preliminary care time history table is configured and updated in such a manner that the third time at which the physiological demand and/or the pathological demand is satisfied is advanced or retarded to the limit execution time. For example, the third party sets the limit execution timing of the first theoretical demand information for diaper replacement to within 3 hours from the time of occurrence. When the time for the baby to get out of bed is monitored to be 2 am, the limit execution time for changing the diaper is 5 am. The time of physiological need for an infant, for example, to suckle, is in the order of 5 am and 8 am. The third closest time is 5 and a half in the morning. The second set threshold may be configured manually by a third party. For example, the second set threshold is set to 0.5 hour. The difference between the limit execution time and the third time is less than the second set threshold value, which indicates that the time interval between the limit execution time and the third time is short, and two times of nursing are not needed separately, and the combination treatment can be performed, so that the third time when the physiological requirement is met, namely, the third time is originally half a day in the morning, can be changed into the limit execution time, namely, five hours in the morning. Preferably, different second setting thresholds can be set for different first theoretical requirements, so that the requirement for the baby can be met to the greatest extent while the nursing times are reduced.
Example 3
This embodiment is a further improvement of the foregoing embodiment, and repeated contents are not described again.
Preferably, the mattress body 9 further has a first receiving area 11 for supporting the head of the infant and a second receiving area 12 for supporting the chest and back of the infant. Preferably, the shape of the mattress body 9 is defined by a rectangle. First inflatable air bags 13 that can slide in the width direction of the mattress body 9 are provided on both sides of the first receiving area 11 in the width direction of the mattress body 9. For example, when an infant is placed on the mattress body 9 and the head thereof can be received by the first receiving area 11, one first inflatable bag 13 is provided on each of the left and right sides of the head of the infant. The first inflatable air bag 13 can be in a deflated and folded state when not in use. When it is desired to use the first inflatable air bag 13, oxygen for rescue can be injected thereinto through an external device such as an air pump 19.
Preferably, the first inflatable air cells 13 are respectively fixed to mounting plates 14, the mounting plates 14 are connected to push rod motors 15, and the push rod motors 15 are provided on both sides of the mattress body 9 in the width direction. The telescopic motion of the push rod motor 15 can drive the two first inflatable air bags 13 to move towards the head of the baby, and then the first inflatable air bags are abutted to the head of the baby. During the sleeping process of the infant, the head of the infant often presents a shape inclined to a certain side due to the sleeping habit of the infant or the influence of the outside. Under the condition of head deflection, the infants are easy to generate respiratory tract blockage, further induce apnea, and in severe cases, also can cause the infants to die by suffocation. The baby head can be pushed to move by the first inflatable air bag 13 moving to abut against the two sides of the baby head, so that the baby head takes the standard posture of facing upwards. The posture of the head of the infant can be corrected firstly when the breathing frequency or the heartbeat frequency of the infant, which is acquired by the physical sign information acquisition device 1 arranged in the mattress body 9, is abnormal through the first inflatable air bag, so that the breathing channel of the infant can be opened conveniently.
Preferably, the side of the first inflatable air bag 13 abutting the head of the infant is provided with a plurality of vent through holes 16. The outside of the first inflatable air bag 13 is also wrapped by a breathable layer 17. The air-permeable layer 17 may be made of, for example, gauze or cotton cloth having good air permeability. Oxygen in the first inflatable air bag 13 can permeate the breathable layer 17 through the exhaust through holes 16 to reach the mouth and nose parts of the baby, so that oxygen supply rescue for the baby can be realized. The provision of the ventilation layer 17 makes it possible to avoid asphyxia of the infant caused by the first inflatable air bag 13 directly adhering to the mouth and nose of the infant even if the first inflatable air bag 13 does not adjust the head of the infant from the inclined posture to the posture with the face facing upward. Preferably, the first inflatable air bag 13 is further provided with a pressure sensor 17 for acquiring pressure data, and the pressure applied to the first inflatable air bag 13 by the head of the infant is acquired through the pressure sensor 17. In the event that the pressure data from the pressure sensor 17 exceeds the set threshold, the push rod motor 15 is deactivated to prevent the first inflatable bladder from moving further towards the infant's head, preventing the occurrence of infant asphyxiation due to excessive compression.
Preferably, a second inflatable bladder 18 is also provided on the second landing zone 12. The second inflatable air bag 18 can assume an inflated state by an inflating means such as an air pump. Under the condition that the physical sign information acquisition device monitors that the breathing frequency or the heartbeat frequency of the infant is abnormal, the chest cavity of the infant can be lifted upwards through the expansion of the second inflatable air bag 18. Preferably, the second inflatable bladder 18 is configured to alternately inflate and deflate at intervals to enable the second inflatable bladder 18 to assume an inflated-deflated-inflated operational configuration.
Preferably, the first inflatable bladder 13 and the second inflatable bladder 18 provide oxygen rescue to the infant to avoid apnea in the infant as follows:
s1: when the respiratory frequency or the heartbeat frequency acquired by the physical sign information acquisition device 1 exceeds a set threshold value and presents an abnormal state, the second inflatable air bag 18 is inflated and deflated in a mode of a set time interval in a first time period. For example, the first time period may be set to within 10 seconds after an abnormality occurs in the breathing frequency or the heartbeat frequency. Through the alternating process of expansion and contraction of the second inflatable bladder 18, at least the following technical effects can be produced: when the second inflatable air bag 18 is inflated to lift the whole chest of the infant upward, the head of the infant gradually becomes suspended, and the head automatically changes from the inclined posture to the face-up posture under the action of the head gravity. The two, baby's head can be based on its self action of gravity and lean on backward, and then can play the extension effect to the trachea of breathing in baby's neck department, and the plug in baby's choke or the trachea can change the position through the back of head this moment, and to a certain extent, can discharge the plug from the oral area through this kind of mode. The second inflatable air bag alternately expands and contracts to play a role similar to slapping on the back of the infant, so that the blockage of the trachea of the infant can be further relieved.
S2: during a second time period, the first inflatable bladder 13 inflates and moves toward one another to provide oxygen assist to the infant against the infant's head. For example, the second time period may be 1min after the end of the first time period. The first inflatable air bag 13 abuts against the head of the infant, so that the discharged oxygen can be sufficiently absorbed by the infant, and the rescue effect can be improved.
S3: in a third time period, when the breathing frequency or the heartbeat frequency of the infant is still in an abnormal state, the early warning can be given to a third-party nursing staff through the cloud server 7.
It should be noted that the above-mentioned embodiments are exemplary, and that those skilled in the art, having benefit of the present disclosure, may devise various arrangements that are within the scope of the present disclosure and that fall within the scope of the invention. It should be understood by those skilled in the art that the present specification and figures are illustrative only and are not limiting upon the claims.
