Description

A kind of with diaper with the use of Respiratory Care device

Technical field

The present invention relates to medical monitoring device field, particularly relate to a kind of with diaper with the use of Respiratory Care device.

Background technology

Sudden infant death syndrome also claims cradle death (cot death, crib death), mean that appearance seems completely healthy baby and dies unexpectedly suddenly, the second itternational SIDS(Sudden infant death syndrome held in Seattle, North America for 1969, newborn baby's Sudden Death Syndrome) meeting specifies that it is defined as: baby dies unexpectedly suddenly, though after death also fail to determine that its cause of death person claims SIDS through postmortem.Sudden infant death syndrome is the modal cause of death between 2 weeks ~ 1 years old, accounts for 30% of this age group mortality rate.Sickness rate is generally 1 ‰ ~ 2 ‰, and its distribution is worldwide, and general midnight to early morning, morbidity was for many, and the death of nearly all sudden infant death syndrome occurs in baby sleep.

Correlational study proves, the breathing pattern of baby and sudden infant death syndrome have larger relation, comprises long-time asphyxia, frequently transient respiratory apnea, periodic breathing frequency deceleration etc.Lacking waking response may be the essential condition that SIDS occurs.SIDS victim may lack (panting) function of automatically reviving, and this is the ingredient lacking the waking response that suffocates.

Educational circles, to the understanding of its mechanism of causing a disease, starts from the Epidemiological study of the 1980's Holland, and finding that lying prone sleeps at that time is one of risk factor of Sudden infant death syndrome.The country such as knob Australia also found to lie prone successively afterwards, and to sleep be important risk factor, sleeps so advocated not lie prone from 1991, the rapid decline of Sudden infant death syndrome incidence rate on this ground of result.The U.S. started suggestion and does not lie prone and sleep in 1992, and initiated " Back to Sleep " motion in 1994, obtained the achievement that sudden infant death significantly reduces equally.

Because sudden infant death and its sleep have greatest relation, if therefore there is a kind of apnea detector effectively can monitoring baby's sleeping position and breathing state thereof, band is helped prevention sudden infant death by that, because apnea detector to be lain prone alarm of sleeping baby, its sleeping position just can be corrected; And occur that the asphyxia initial stage reports to the police at baby sleep, thus have an opportunity to wake baby up in time, make it recover to breathe thus prevent unexpected generation of dying suddenly.

Current existing infant breathes testing product has different forms, comprises contact and contactless.Contact have baby's fine motion checkout gear, breast binder type device for detecting respiratory etc., and contactless have microwave respiration monitoring device, high sensitivity mattress fine motion monitoring device etc.

Microwave monitoring of respiration price is obviously somewhat expensive, and people also hamper the application of its universalness to the worry of microwave radiation.Baby's fine motion for contact is monitored, and has a kind ofly not use on baby's trousers, the softness probe that this device has to protract, during use, the abdominal part of this probe contacts baby can respond to its respiratory movement, if but fixing bad, probe and baby's abdominal section from, just there will be false alarm.

Then comparatively simple and practical as breast binder type respiration detection, its main deficiency is that monitored person will by the constraint of breast bellyband when sleeping, and if constraint loosely also can affect the effect of detection.Although decline to move as mattress and monitor the constraint that it relieves breast bellyband, but need very high sensitivity due to during work, this is easily by extraneous interference, such as noisy environment, on road, vehicle crosses, the blowing over of mild wind outside window, all likely interferes with testing result, even if really there is infant breathes suspending event to occur also may not necessarily detect in this case.

Please refer to shown in Fig. 1, this is the schematic diagram of conventional diaper when normally using.In figure, 10 is the diaper (baby or adult diaper are all applicable) of a routine, diaper is divided in two parts, the first section is abdominal part, back part is buttocks, from back part extend to form left and right (with towards reader for reference) two surrounding edges 11,12, surrounding edge 11,12 is respectively equipped with an adhesive subsides button 16,18, left and right two surrounding edges 11,12 can be strained and abdomen pastes on 15 before being fixed on diaper, thus the abdominal part of parcel user that two parts before and after diaper are connected together and buttocks.The benefit of this structure is that dress is convenient, and left and right is pasted, and button can the random attaching difference of pasting at front abdomen be local as required, to regulate size and the degree of tightness of diaper waistline.

Paste about conventional diaper and be buckled with two kinds of bonding methods, one uses gum, gum cohesively, Pasting abdomen before being designed to smooth plastics thin film pastes on 15, and repeatedly can paste use, check that the urine of diaper wets situation to facilitate to untie, or regulate the elasticity of diaper.Another kind of bonding method adopts Velcro (Hook & Loop), and Velcro is called again double buckle or nylon buckles, and its one side is the fiber garden hair (Loop, below referred to as hair side) of small, flexible, can be arranged on front abdomen and paste on 15; The another side of VELCRO is the seta (Hook, below referred to as thorn face) compared with stiff ribbon hook, and can be arranged on the left and right subsides button 16,18 of diaper, left and right like this subsides button 16,18 and front abdomen just can produce viscous force between pasting 15 and repeatedly can paste use.

Please refer to shown in Fig. 2, this be the embodiment of the present invention one with diaper with the use of the structural representation of respiration monitoring device.In figure, 10 is the diaper shown in Fig. 1, comprise the surrounding edge 11,12 of left and right both sides waistline, be separately positioned on the subsides button 16,18 on surrounding edge 11,12, the front abdomen that left and right subsides button 16,18 is pasted onto diaper 10 respectively pastes on 15, thus the abdominal part of parcel user that two parts before and after diaper are connected together and buttocks.Except the basic structure of these conventional diaper above-mentioned, the respiration monitoring device of the present embodiment also comprises tool first component 21 at regular intervals and second component 22, wherein, first component 21 is arranged on left side thread gluing 16 and front abdomen pastes between 15, and second component 22 is arranged on right side thread gluing 18 and front abdomen pastes between 15.Particularly, first component 21 and second component 22 are pasted onto thread gluing 16,18 respectively and front abdomen pastes between 15, gum also can be divided into paste for its mode of pasting and VELCRO is pasted, preferred VELCRO bonding method in the present embodiment, but its ultimate principle is also equally applicable to gum stickup.First component 21, second component 22 paste towards front abdomen the thorn face that 15 sides are provided with VELCRO, and Pasting abdomen before being provided with VELCRO hair side pastes on 15.The surface of pasting 15 due to front abdomen is covered by parts such as first component 21 and second components 22, occupy about originally keeping for diaper and paste button 16, 18 places of pasting, in order to address this problem, the present embodiment first component 21 and second component 22 dorsad before abdomen paste the hair side that 15 sides are provided with VELCRO, the left and right of diaper 10 is made to paste button 16, 18 can directly be pasted onto on first component 21 and second component 22 respectively, before so not only can playing replacing paper urine pants, abdomen pastes the stickup fixation of 15, dual fixation is played to first component 21 and second component 22 simultaneously, the breathing tension force of diaper user is made can be effectively delivered on first component 21 and second component 22.

The object making the breathing tension force of diaper user can effectively be delivered on first component 21 and second component 22 is, the present embodiment realizes the monitoring to breathing state by the sensor be arranged in first component 21 and second component 22.

Please refer to shown in Fig. 3, this is the configuration schematic diagram of each associated components of the respiration monitoring device of the embodiment of the present invention one.20 cross sections representing user (baby or adult) abdominal part in figure, first, second parts 21,22 are arranged at the arranged on left and right sides of preabdomen respectively along user abdominal surface 20, lie low when user is in (lying on the back) position time, first component 21 is a with the angle of horizontal level, and second component 22 is b with the angle of horizontal level.It should be noted that, horizontal level herein refers to horizontal plane, when namely user lies low, and the plane tangent with diaper preabdomen center.

In this case, when the wearer breathes, its abdominal surface 20 can with respiratory movement in periodic fluctuations.Because first, second parts 21,22 are all within the abdominal respiration moving region of user, in the ordinary course of things, first, second parts 21,22 are except the component having vertical change, and also have a component moved left and right, this component can cause horizontal sextant angle a, b to change.

Please refer to below shown in Fig. 4, this is the schematic diagram that the inclination angle (or position) of one of them parts (first component 21) of the respiration monitoring device of the embodiment of the present invention changes with user respiratory movement again.In figure, A1 is the situation (abdominal part because of expansion raise) of user when making abdominal breathing exercise air-breathing, and corresponding horizontal sextant angle is a1.In figure, A2 is the situation (abdominal part reduces because of contraction) that user does when abdominal breathing exercise is exhaled, and the horizontal sextant angle of its correspondence is a2.When user eupnea, described angle, just in the catch cropping cyclically-varying of a1 and a2, by the detection to described angle, just can know breathing state and the breathing cycle of user, and the respiratory frequency can measuring user is thus come.

Detection for variable angle has multiple diverse ways, the present embodiment adopts at first component 21 and second component 22 inner each self-configuring obliquity sensor, in this case, first, second parts 21,22 aforesaid can be referred to as first, second obliquity sensor.Obliquity sensor can detect himself angle of inclination, by the continuous monitoring to described angle of inclination, just can know the breathing state of user, and calculate its breathing cycle and respiratory frequency.In order to reach best monitoring effect, obliquity sensor adopts Gravity accelerometer (also known as gravity sensor, Gravity Sensor, G-Sensor etc.), particularly preferably three axles (or more) Gravity accelerometer, it can export the numerical value of X, Y, Z tri-axis, being configurable on user abdominal part embodies within respirometric region, it not only has higher sensitivity, also has good reliability simultaneously.Simultaneously because three axle Gravity accelerometers can provide clear and definite 3D positional information, therefore more accurately can also judge the sleeping posture of user, such as, can differentiate the lying on the back of baby, lie on one's side, the sleeping position such as prostrate (lie prone and sleep).

In actual applications, not must detect the horizontal sextant angle of obliquity sensor, as long as in fact detect that any one angle in X, Y, Z axis changes, the respiratory movement state of user can be judged, by the further statistical analysis to respiratory movement rule, the breathing cycle information of user can also be obtained, and then the respiratory frequency of user can be calculated.

In the present embodiment, adopt two (or more) be configured in user abdominal respiration moving region, and be in diverse location, different towards or the tool sensor at regular intervals of differing tilt angles carry out the breathing state of monitoring user, than employing single-sensor, or by two (or more) sensor configuration more effective in same place (or same towards/angle of inclination), reason is as follows:

1, avoid the appearance of check frequency: although the abdominal part of user can with respiratory movement fluctuations, but on some ad-hoc location, such as the lie on the back inclination angle of abdominal part center of user can't change because of the fluctuating of described abdominal part, namely there will be so-called " translation " region (only moving up and down), which forms the blind area that an angle detects.Because the sleeping position of user can change at any time, therefore described blind zone position has uncertainty.The present embodiment select two (or more) diverse location, different towards or the monitoring point of differing tilt angles just can effectively address this problem, and guarantee has a minimum test point effective change of pitch angle can occur in most cases.

2, improve the reliability of capacity of resisting disturbance and data: in order to reach best Detection results and cost benefit, the embodiment of the present invention is two sensors be separated preferably, and by described sensor balanced configuration on the position, the diaper left and right sides of user preabdomen (as Fig. 2, shown in 3), this can not affect the sleep of user on the one hand, order can produce larger span again on the one hand, and produce obvious change of pitch angle, and described change of pitch angle has symmetry, detect simultaneously and compare the capacity of resisting disturbance that two symmetrical change of pitch angles can improve device greatly, data are made to have higher credibility.

The respiration monitoring device of the present embodiment also includes the parts that can analyze the output of sensor, judge, calculate, process, to obtain user breathing state information accurately and reliably.Can microprocessor be adopted in actual applications, other similar device can certainly be adopted, just can as long as corresponding data processing function can be realized.

Please refer to shown in Fig. 5, the waveform schematic diagram that the inclination angle for the first component 21 of the respiration monitoring device of the embodiment of the present invention one changes with user respiratory movement, this is the abstractdesription of the change of pitch angle to first component 21 shown in Fig. 4.Suppose in figure that the respiratory movement of the angle of first component 21 and horizontal level with user generating period between a1 and a2 changes.

Please refer to below shown in Fig. 6, this is the Gravity accelerometer signal output apparatus figure of the respiration monitoring device of the embodiment of the present invention again.In figure, 23 for being included in three axle Gravity accelerometers in aforementioned first component 21 or second component 22, and its voltage including Xout, Yout, Zout tri-axles exports.These voltages are exported to A/D input (analog digital conversion input) of microprocessor further, to carry out sampling analysis to the output of Gravity accelerometer 23, the obliquity information of Gravity accelerometer 23 can be obtained thus, by just can know the sleeping position of user to the analysis of described obliquity information, or the breathing state of change information monitoring user according to described Gravity accelerometer 23 inclination angle, and come according to the respiratory frequency information that periodic change of pitch angle waveform calculates user further.

Please refer to below shown in Fig. 7, this is the Gravity accelerometer signal output waveform figure of the respiration monitoring device of the embodiment of the present invention again.Suppose in figure that described Gravity accelerometer is placed on first component 21 shown in Fig. 3, and be the change of pitch angle (as shown in Figure 5) of a1 ~ a2 as amplitude with the respiratory movement of user.Suppose that this change of pitch angle directly acts on the X-axis of Gravity accelerometer again, make X-axis also change in the angular range periodically of a1 ~ a2, produce the voltage exporting change of Va1 ~ Va2 thus.Suppose that the sensitivity of this Gravity accelerometer is 1000mV/g more further, and a2, a1 are respectively 29 ° and 31 ° (namely changing in the scope of 30 °+-1 °), then the relative signal of Xout when 29 ° and 31 ° exports as Sin(29 °) x 1000mV and Sin(31 °) x 1000mV, i.e. Va2=485mV and Va1=515mV.In above-mentioned algorithm, get sine to horizontal sextant angle is numerical value in order to obtain its vertical component, because the perpendicular component of the output of described Gravity accelerometer is directly related.When being in complete upright position (90 °), described vertical component is just 1g; Vertical component when being in 30 ° is 0.5g; The vertical component of 0 ° of position (i.e. horizontal level) is 0g.By above-mentioned calculating, the monitoring to user breathing state conveniently can be realized; By the periodically variable analysis to respiratory waveform, the respiratory frequency of user can be calculated.

Please refer to shown in Fig. 8, this is the functional module block diagram of the respiration monitoring device of the embodiment of the present invention one again.First component 21 and second component 22 are all built-in with obliquity sensor, obliquity sensor exportable with user respiratory movement the dip angle signal of periodically-varied.Obliquity sensor preferably three axles (or multiaxis) Gravity accelerometer of the present embodiment, so just, exportable X, Y, Z tri-axis information, order to the respirometric monitoring of user more comprehensively, accurately and effectively, simultaneously can also according to the sleeping posture judging user for information about, the lying on the back of such as differentiation baby, lie on one's side, prostrate (lie prone and sleep) posture.Microprocessor 30 can be positioned within first component 21 or second component 22, all there is electrical connection with two obliquity sensors, the output signal of obliquity sensor can be received, thus realize effectively monitoring user breathing state, as long as because user has respiratory movement, just the X of described Gravity accelerometer can be made, Y, Z axis exports generating period change, this not only can confirm the respirometric existence of user, pass through X simultaneously, Y, the analysis of Z axis output signal rule, also can confirm the breathing cycle of user further and calculate the respiratory frequency of user.Breathing state indicator is used for indicating according to the breathing state of judged result to user of microprocessor 30, and reports to the police when microprocessor 30 judges that adnormal respiration state appears in user, mainly comprises audible-visual annunciator 32.Such as when microprocessor 30 can't detect X, Y, Z axis change time, just describe and respirometric existence cannot be detected, just there is the apneic state of so-called user in this, if this state is continued above the time (such as 15 ~ 20 seconds) that intervalometer 31 sets, microprocessor 30 just can start alert program, and can be placed within arbitrary obliquity sensor by audible-visual annunciator 32() sound and light signal report to the police.Microprocessor 30 also can judge the sleeping position of baby's user according to the output of Gravity accelerometer in addition, can implement to report to the police when being found to be and lying prone and sleep, and this also can reduce the incidence rate of sudden infant death syndrome greatly.

In order to realize long-range monitoring and warning breathing state indicator also comprises wireless transmitter 33, wireless receiver 34 and display/alarm 35, launch, receive and show breathing state information, warning message and the apnea alarm information etc. of sleeping of lying prone of user by wireless mode (such as Wi-Fi, bluetooth, Zigbee, low-power wireless etc.), so just effectively expand the monitoring range of user.

Be described below in conjunction with Fig. 9 ~ 13 pair embodiment of the present invention two.

Please refer to shown in Fig. 9, the embodiment of the present invention two and diaper with the use of respiration monitoring device, compared with embodiment one, difference is: between first component 21 and second component 22, add the 3rd parts 28, first component 21 and second component 22 is linked together.With first component 21 and second component 22 similar, the front abdomen that 3rd parts 28 are also pasted onto diaper 10 pastes on 15, the preferred bonding method of the present embodiment is VELCRO mode, 3rd parts 28 paste towards front abdomen the thorn face that 15 sides are provided with VELCRO, are pasted onto the front abdomen being provided with VELCRO hair side and paste on 15.3rd parts comprise the 3rd sensor, and for the sleeping posture of monitoring user or because breathing tension force, the abdominal part that produces changes and exports corresponding signal.

Again as shown in Figure 10, this is the configuration schematic diagram of each associated components of the respiration monitoring device of the embodiment of the present invention two.20 cross sections representing user (baby or adult) abdominal part in figure, first component 21, second component 22, the 3rd parts 28 are arranged at the side, left, center, right of preabdomen respectively along user abdominal surface 20, lie low when user is in (lying on the back) position time, first component 21 is a with the angle of horizontal level, second component 22 is b with the angle of horizontal level, and the 3rd parts 28 are 0 with the angle of horizontal level.

In this case, when the wearer breathes, its abdominal surface 20 can with respiratory movement in periodic fluctuations.Because first, second, third parts 21,22,28 are all within the abdominal respiration moving region of user, in the ordinary course of things, the 3rd parts 28 do vertical fluctuating, and the angle of itself and abdominal part is constant; And first, second parts 21,22 are except the component having vertical change, also have a component moved left and right, this component can cause horizontal sextant angle a, b to change.Relevant angle a, b change schematic diagram and please refer to shown in Fig. 4 and Fig. 5.

3rd parts 28 are compliant member 28, be provided with one in it and there is flexible piezoelectric transducer or voltage sensitive sensor (abbreviation flexible sensor), two, the left and right of described flexible sensor is separately fixed on first, second parts 21,22, like this when first, second parts 21,22 are with the respiratory movement of user, (during a, b) generating period change, the flexibility (diastrophic degree) of flexible sensor 28 also can generating period change thereupon for its horizontal sextant angle.The angle supposing first, second parts 21,22 extension line is c, then c=b-a.When the wearer exhales the air, b increases and a reduces, and angle c numerical value becomes large, and the flexibility representing flexible sensor 28 diminishes; And when the wearer inhales the air, b reduces and a increases, angle c numerical value diminishes, and the flexibility representing flexible sensor 28 strengthens.Because first component 21 and second component 22 tool are at regular intervals, an effective span can be produced, the order flexible sensor be in the 3rd parts 28 between span can produce the flexible bending distortion of an efficient periodic with the respiratory movement of user, realize respiration monitoring function equally, be equivalent to outside first component 21 with second component 22, increase again the device of a monitoring breath state newly, made monitoring more comprehensively.

Above-mentioned flexible sensor can be flexible piezoelectric sensors, also can be flexible pressure-sensitive sensor, concrete:

Flexible piezoelectric sensors 28 can adopt soft piezoelectric, and such as piezopolymer, comprises segregation fluorothene (PVDF) thin film etc. and take on.A just exportable voltage as long as this piezoelectric membrane occurs bending and deformation, diastrophic speed is faster/and degree is higher, its voltage exported is also larger, the diastrophic situation of described sensor and cycle can be known thus, thus the state that user is breathed can be judged further, minimum can judge user whether have occur apneic state.In asphyxia situation, no signal is exported (or outputing signal unchanged) by piezoelectric transducer.Segregation fluoroethylene film has good flexibility (elasticity) and quite high sensitivity, is applicable to very much the present embodiment and uses.

Can adopt soft pressure sensitive conductive material as flexible pressure-sensitive sensor 28, such as pressure sensitive conductive composite, or pressure-sensitive conductive rubber material (PCR) etc. forms.These are all the sensitive materials with resistance strain effect, are also called pressure-sensitive conductive material.When without External Force Acting (or without flexural deformation), the resistance value of described pressure sensitive conductive material is higher, and be stressed when adding (or produce flexural deformation) time, its resistance value obviously reduces, and the character of display conduction.By can know the breathing state of user to the detection of described resistance value, such as, whether there is apneic state.In addition, by the detection to user respiration motion cycle, the parameters such as the respiratory frequency of user can also be calculated, can the respiratory health situation of more effective monitoring user.

The present embodiment, on the basis of the embodiment of the present invention one, increases flexible 3rd parts, plays the effect of sensor equally, monitor user breath state, further enhancing reliability and the accuracy of monitoring.In addition, the flexible sensor arranged by the present embodiment the 3rd parts can be known by inference, obliquity sensor in first component 21, second component 22 in the embodiment of the present invention one is replaced with the flexible sensor of the 3rd parts in the present embodiment, the piezoelectric signal change produced by the flexural deformation of monitoring flexible sensor can be played too, to the effect that user situation of breathing is monitored, concrete principle is described above, repeats no more herein.
