Abstract

The utility model relates to a monitor for providing omnibearing monitoring for newborns. The utility model is composed of a host machine, a respiration sensor, a body temperature sensor and a urine moisture sensor. The respiration sensor, the body temperature sensor and the urine moisture sensor can be put in a loose covering for the breast, signals of the human body are picked up, and whether the sending out signals of the operation is normal is dectected by the host machine. The utility model has multifunction with one machine, and the requirements of the health growth of the babies can be well solved. The problem of the parents can be relieved, and the burden of the parents are also lightened. The utility model has the advantages of simple structure and convenient operation. The monitor is the necessary tool for newborns.

Description

The multifunctional infant monitor

This utility model relates to a kind of instrument that newborn infants is provided multi-faceted monitoring.

Breathing is a kind of basic life movement, the breathing that continues nature is healthy important symbol, clinical medicine shows, the ewborn infant respiratory center is grown not perfect, often has the asphyxia phenomenon to occur under sleep state, as untimely discovery, relief in time, will cause lasting anoxia, cause brain cell necrosis, even threat to life.The delicacy of infant skin, if untimely more changing babies' napkin is easy to cause buttocks red, the slight red meeting of buttocks causes the infant pruritus, the influence sleep if buttocks is red to be further developed, can cause buttocks to infect on every side and form septicemia, threat to life.In addition, scleroderma neonatorum takes place easily when infant body temperature is lower than 35.5 ℃, body temperature is higher than 37.5 ℃ and then should in time seeks medical advice.At infant these requirements in growing up healthy and sound, medical circle and scientific research institution more and more pay attention to developing relevant instrument and equipment.China does not also have sophisticated this type of launch products at present.

The purpose of this utility model is, provide a kind of can be to the breathing of infant, situation such as body temperature and urine are wet, a kind of instrument of monitoring.

This utility model is achieved in that monitor is made up of main frame and wherein circuit board, set of cells, power supply, display lamp, and pick off is made up of respiration pickup, body temperature trans, urine wet sensor respectively.Respiration pickup and body temperature trans are placed in the bellyband of infant, and to pick up human body signal, urine wet sensor is placed on the outside of bellyband, links to each other with main frame.

In circuit based on detection module, breathing, body temperature trans link to each other with module, and urine wet sensor links to each other with module through urinating wet testing circuit, and module detects the signal of being imported, be transferred to warning circuit after storage is analyzed, detection module determines whether to report to the police or send normal signal.

Respiration pickup adopts strain gage, and foil gauge is affixed on the fritter copper sheet, and copper sheet lies in the abdominal part of health, the curvature variation when breathing to pick up abdominal surface by the belt that links to each other with bellyband.Body temperature trans adopts the PN junction voltage of diode or triode to vary with temperature and the principle pickoff signals that changes.Urine wet sensor utilizes then that urine is wet to have certain conductive capability, and then detects resistance variations between two electrodes, and output signal is for the further analyzing and processing of main frame.Link to each other by holding wire between bellyband and the main frame, send the signal of being surveyed to main frame.

With reference to the accompanying drawings this utility model is further described below:

Fig. 1 is the shape assumption diagram of multifunctional infant monitor.

Fig. 2 is the theory diagram of multifunctional infant monitor.

Fig. 3 is the circuit diagram of multifunctional infant monitor.

In Fig. 1, wherein main frame (4) is by circuit board (7), set of cells (8), on and off switch (6), display lamp (5) is formed, and pick off has respiration pickup (1) respectively, body temperature trans (2), urine temperature sensor (3), respiration pickup (1) and body temperature trans and the bellyband of being made by cotton (9) are formed one.Respiration pickup (1) is placed on the right side of bellyband (9), to measure the temperature at human liver position.Urine wet sensor (3) is placed on the outside of bellyband (9), links to each other with main frame.

Fig. 2 is a theory diagram of the present utility model.

The output of respiration pickup and body temperature trans directly is connected to breathes the temperature check module, this module is with the rate detection signal of sensor of per second 5 times, and with the output buffers of respiration pickup 15 seconds, analyze institute's deposit data simultaneously in storage, if data change human abdomen not motion, i.e. respiratory arrest are not described then.So drive sound light alarming circuit in advance reporting to the police, if institute's deposit data period of change is less than 1 second, promptly frequency of respiration is sent warning equally greater than 50 times/second, otherwise module is sent the eupnea indication, breathe display lamp bright dark with breathe synchronously.The body temperature trans operation principle is identical with respiration pickup, and its module links to each other with the audible alarm circuit with the luminous tube indication respectively.Urine wet sensor is connected the back with the wet testing circuit of urine and joins with module.

Fig. 3 is a circuit diagram of the present utility model

HS01 is a special module, be used for will input signal compare, again with the output buffers certain hour of signal, analyze institute's deposit data simultaneously, to determine that normally whether signal in storage.N ₂, R ₄For constant-current source circuit links to each other with respiration pickup and power supply respectively.2.3 feet of HS01 module are the respiration detection input pin, 9 feet output 1.235V reference voltage provides reference potential for peripheral circuit, 6 feet are the temperature sensor signal input, in HS01 inside temperature signal is amplified in advance, and regulate zero point by 7 feet, the temperature signal after the output of 27 feet is amplified is connected to by N ₃: B and N ₁: the temperature bound comparator that C forms, N ₃: B is a upper limit alarm, is set in 37.5 ℃, N ₃: C is that lower limit is reported to the police, and is set in 35.5 ℃, and comparator output is connected to 14,15 feet of HS01, finishes monitoring, alarming by HS01.

25 feet of HS01 connect press button, are used for the use of functions such as design temperature warning.

R ₉, C ₁, N ₁Form humidity measuring circuit, when humidity acquired a certain degree, 11 feet of HS01 detect level to be changed, and sends urine-wet alarm.

N ₅, N ₆, N ₇, N ₈Be condition prompting luminous tube, wherein N ₅Be used to show breathing rate, N during adnormal respiration ₆Light N during temperature anomaly ₇Light N when urine is wet ₈Light.

R ₁₉, N ₉, N ₁₀, BL is the audible alarm circuit, when above-mentioned three kinds of one of unusual appearance, the warning of all sounding.

Circuit adopts 5 _#Battery powered is established on and off switch S2.

The utlity model has a tractor serves several purposes, finely solved infant these requirements in growing up healthy and sound, removed the head of a familys' a difficult problem, alleviate their burden, this product structure is simple, and is easy to use, is the infant necessary tool.
