Abstract
The utility model discloses a kind of vital signs device, it is related to technical field of electronic communication, including：Sense pad body and Signal Processing Element；Wherein, sensing pad body further comprises：At least one friction sensor and encapsulated layer, wherein, at least one friction sensor, is corresponding electric signal for the pressure conversion by the vital sign effect of object to be monitored on it；Encapsulated layer, is coated on outside at least one friction sensor, at least one friction sensor of sealing protection；Signal Processing Element, is connected with least one friction sensor in sensing pad body, and the electric signal for being exported at least one friction sensor is handled, and the vital sign for determining object to be monitored is analyzed according to handling result；Wherein, vital sign includes at least one of the following：Breathing, heartbeat and body action.The vital sign information of the vital signs device real-time monitoring object to be monitored of the utility model, and to the abnormal phenomenon and alarm of appearance.
Description
Technical Field
The utility model relates to an electronic communication technical field, in particular to vital sign guards device.
Background
It is estimated that about 1500 million babies born per year are premature babies who fail to complete 37 weeks of gestation, with about 100 million babies dying from the complications of premature delivery. In the premature delivery complications, the premature infant has a very high probability of respiratory problems, which is the biggest killer of health problems and death of the premature infant, and a professional respiratory heartbeat device is needed for timely monitoring so as to effectively reduce the probability of respiratory problems. Studies have found that 80% of infant deaths can be associated with unsafe sleep patterns. This abnormality, which is mostly found in infants under 1 year of age, is called "sudden infant death syndrome" medically, SIDS for short, and is the first cause of death in infants under 1 year of age. For example: recently, a disease called Sudden Infant Death Syndrome (SIDS) frequently exposed in news is the most common cause of death of infants between 2 weeks and 1 year, accounts for 30% of the death rate of the age group, the morbidity is generally 1-2%, the distribution is worldwide, the peak of the disease is 2-4 months after birth, the disease is generally developed from half night to early morning, almost all deaths of the sudden infant death syndrome occur in the sleep of the infants, the cause and the solution of the disease are not found so far, and the most effective prevention measure at present is to monitor the heart and lung of the infants. And according to statistics, the newborn sleeps for at least 16 hours every day, and high-quality sleep can help the newborn to grow healthily and promote intelligence development, so that the guarantee of the sleep health of the newborn is the most important thing for novice parents and caregivers.
However, the inventor is realizing the utility model discloses an in-process discovery, at present, some auxiliary assembly that guardianship carries out the infant has appeared on the market, however, the monitoring rate of accuracy of these equipment is all lower, in addition, some equipment though structure, manufacture craft, installation and simple to use, low cost, but the function is single, can not realize the monitoring to infant's breathing, heartbeat and health position simultaneously, and other equipment have realized the monitoring to infant's breathing, heartbeat and health position simultaneously, but structure, manufacture craft, installation and use are complicated, and are with high costs, have brought very big difficulty for the use.
Therefore, the prior art lacks an infant monitoring device which can simultaneously monitor the breathing, heartbeat and body position of an infant, has high monitoring sensitivity and accuracy, and is simple in structure, manufacturing process, installation and use and low in cost.
SUMMERY OF THE UTILITY MODEL
The utility model provides a vital sign guardianship device for monitoring device sensitivity and the rate of accuracy among the solution prior art are low, and structure, preparation technology, installation and use are complicated, the high scheduling problem of cost.
The utility model provides a vital sign guards device, include: the sensing mat comprises a sensing mat body and a signal processing component; wherein,
the sensor mat body further comprises: the device comprises at least one friction sensor and an encapsulation layer, wherein the at least one friction sensor is used for converting pressure acted on the friction sensor by vital signs of a subject to be monitored into corresponding electric signals; the packaging layer is coated outside the at least one friction sensor and used for sealing and protecting the at least one friction sensor;
