Description

The urine-wet alarm apparatus of wet diaper of disposable electric sense and separable reuse

Technical field

The present invention relates to a kind of diaper and alarm apparatus, the urine-wet alarm apparatus of wet diaper of particularly a kind of disposable electric sense and separable reuse.

Background technology

Disposable diaper is very popular in the world at present, and disposable diaper both used up and abandons, and is more healthy and convenient undoubtedly with respect to traditional diaper.Disposable diaper is made up of dry and comfortable layer (internal layer), moisture absorption layer (interlayer) and impervious barrier (skin) usually, and dry and comfortable layer is the innermost layer of diaper, and when the baby urinated, urine can be passed dry and comfortable layer and be absorbed by moisture absorption layer, thereby made dry and comfortable layer be kept dry and comfortable.Yet this dry and comfortable be relative, the wettability power that is moisture absorption layer on the one hand is limited, be that urine also can be distributed moisture at moisture absorption layer on the other hand, impervious barrier is ventilative inadequately because will prevent urine from leaking simultaneously, the gas that urine is decomposed in moisture absorption layer can be retained within the diaper for a long time, this has stimulation to infant skin, so diaper urine should change after wet as early as possible, to keep the health of infant skin.

Because the closeer comparatively speaking gas of disposable diaper, be not easy to observe diaper generally speaking and whether urinated wetly, particularly when the ward is busier, often ignore the replacing of wet diaper easily, cause the problem of infant skin.Therefore in real life, need a kind of prompting mode of more effective, initiative really, when diaper urine is wet, remind the ward to carry out the replacing of diaper, make baby's skin health more secure.Similarly disposable diaper also is suitable for the old man or the patient of gatism, this can be to urinating the diaper that wet situation be carried out the initiative prompting and be reported to the police, the raising of the service quality of mechanisms such as hospital, sanatorium, nursing homes, care centre do not had be suspected to have certain help.

At present existing diaper with the wet deictic function of urine is mainly realized by chemical mode, promptly is to coat a kind of chemical reagent at the outer inner edge of diaper, thereby its color changes and realizes the indication that urine is wet when urine is wet.This indicating mode has two shortcomings, and the one, chemical reagent is coated on the outer inner edge of diaper, because diaper is outer and not exclusively transparent, so the change of its color and be not easy to observe; The 2nd, this color change is a kind of passive type of alarm, and it can initiatively not tell the ward to go to change one to have urinated the diaper that has wet.

Can realize that the device of active urine-wet alarm mainly is the electronics urine-wet alarm device, existing on the market at present electronics urine-wet alarm device mainly is divided into two classes, one class is a built-in disposable urine-wet alarm device in disposable diaper, this alarm is built-in when diaper production, and after use, abandon with diaper, this class alarm major defect is that cost is somewhat expensive, and the sound of reporting to the police too little (because built-in), and do not have flashing warning-function (because can't see), can't in existing diaper products, realize the warning function that urine is wet simultaneously yet; Another kind of is the wet induction alarm device of repeatedly used urine, this class device is the internal layer (dry and comfortable layer) that puts within the diaper from the diaper outside by waistline (or lower limb encloses) pick off earlier and be affixed on diaper in use, urine just can trigger warning when wet, when diaper change, take out then, after cleaning, can reuse.The wet induction alarm mode major defect of this class urine is the internal layer that pick off need be positioned over diaper, user can be felt uncomfortable (because pressing close to very much skin), the wet induction of urine simultaneously too sensitive (because touching Excreta too easily), cause false alarm (for example perspiring) easily, also need after use, clean simultaneously, not too convenient also not enough health, the adult who particularly is not suitable for hospital, nursing homes and care centre uses.

Summary of the invention

Technical problem to be solved by this invention is, deficiency at above-mentioned existing product technology, wet diaper of a kind of effective sense electronics and alarm apparatus are provided, once cross solve that it produces in using functional, comfortableness, reliability, and problems such as health and cost.

In order to solve the problems of the technologies described above, the embodiment of the invention provides the urine-wet alarm apparatus of wet diaper of a kind of disposable electric sense and separable reuse, comprise diaper and alarm, described diaper comprises internal layer, skin and moisture absorption layer, also include independently dry and comfortable space, this dry and comfortable space can enter outside diaper and use, and described alarm is fit to be positioned in this space, and realizes wet induction of urine and warning function in this space.The embodiment of the invention also provides a kind of disposable electric sense diaper that wets, and comprises internal layer, skin and moisture absorption layer, also includes independent dry and comfortable space simultaneously, and is positioned at the outer inner edge of diaper and with moisture absorption layer the conduction line of induction that contacts is arranged.The embodiment of the invention also provides a kind of urine-wet alarm apparatus of separable reuse, comprises contact electrode, elasticity folder, sensing input circuit, warning output loop, processor and wireless transmitter.

The beneficial effect that the present invention has is: the first, and it is the wet induction of urine and the alarm device of an electronization, can realize the urine-wet alarm of initiative; The second, it is an external device, and promptly alarm can be placed on outside the moisture absorption layer of diaper, can not produce uncomfortable feeling in use; The 3rd, pick off away from skin, can effectively prevent to perspire or slightly drains the false triggering that causes when using; The 4th, diaper is disposable, with after promptly abandon the clean and health that has guaranteed to use; The 5th, alarm and diaper are can be isolating, and alarm can reach repeatedly repeatedly and use, and this has reduced the cost that uses effectively; At last, alarm installation of the present invention and separation are all very simple, are suitable for all kinds of personages and use.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

Please refer to shown in Figure 1ly, this is that the urine-wet alarm device of wet diaper of disposable electric sense of the present invention and separable reuse is installed on the typical schematic appearance when using.Among the figure, 10 is the main part of disposable diaper (hereinafter to be referred as diaper) described in the invention, 11 is the diaper waistline, angle from 10 and 11, its the basic outward appearance and the mode of wearing are the same with traditional disposable diaper, certain position (being the place ahead of diaper or rear among the figure) that different is outside diaper is provided with an independently dry and comfortable space 12, an opening (inlet) 13 is arranged on the dry and comfortable space, can can insert alarm 20 in the porch, a display lamp (LED is arranged on the alarm, light emitting diode) 21, can do the indication of work state or wetting state.Also further include an elasticity folder 22 on alarm, this elasticity folder can be sandwiched on the independent dry and comfortable spatial outward flange, so that alarm is fixed.

The design of Fig. 1 has been mainly the technical deficiency that solves existing disposable diaper product and has put forward.The first, it is the wet induction of urine and the alarm device of an electronization, can realize the urine-wet alarm of initiative; The second, it is an external device, and promptly alarm can be placed on outside the moisture absorption layer of diaper, can not produce uncomfortable feeling in use; The 3rd, pick off away from skin, can effectively prevent to perspire or slightly drains the false triggering that causes when using; The 4th, diaper is disposable, with after promptly abandon the clean and health that has guaranteed to use; The 5th, alarm and diaper are can be isolating, and alarm can reach repeatedly repeatedly and use, and this has reduced the cost that uses effectively; At last, alarm installation of the present invention and separation are all very simple, are suitable for all kinds of personages and use.

Please refer to shown in Figure 2ly again, this is a then cutaway view (before the assembling) of the alarm side view of the embodiment of the invention one and diaper.Among the figure, 11 is the diaper waistline, and 15 is diaper skin (impervious barrier), and 16 is diaper moisture absorption layer (interlayer), and 17 is diaper internal layer (dry and comfortable layer).Skin at diaper has an opening 13, and an antiseepage protective layer 18 is arranged under the opening, and protective layer is covered under the diaper opening, and its four limit is pasted on the outer inner edge of diaper, can prevent that urine is in the opening part seepage.Meanwhile, protective layer also forms independently dry and comfortable (ne-leakage) space 12 with the outer inner edge of diaper is common, and this space can directly be touched by the outer opening of diaper from the outside of diaper, and can be used by the user.In the present invention, the dry and comfortable space of this independence is mainly used in and lays the wet induction alarm apparatus of (placement) urine.In addition in the drawings, 20 is alarm (or alarm body device, in comprise the wet induction alarm circuit of urine), and 22 press from both sides for elasticity, and 23 is contact electrode, and auspicious feelings are with further instruction in the relevant below legend.

Please refer to shown in Figure 3ly again, this is a then cutaway view (assembling back) of the alarm side view of the embodiment of the invention one and diaper.Each accompanying drawing mark is the same with Fig. 2 among the figure, here will not give unnecessary details, different is that alarm 20 is placed within the dry and comfortable space 12 of diaper, alarm elasticity folder is then clamped dry and comfortable spatial outward flange 14 (for the part of diaper skin 15) from diaper is outside, this is used for fixing between alarm and the diaper on the one hand, make the conduction line of induction that depends on the outer inner edge of diaper and contact electrode on the alarm can have one on the other hand and contact (increase contacts elastic force) reliably, this also has further description in Fig. 4.

Please refer to shown in Figure 4ly again, this is the expanded view of the outer inner edge of diaper of the embodiment of the invention one.11 is the waistline of diaper among the figure, and 15 is the cladding material of diaper, and 19 is two conduction lines of induction, after the diaper molding, the conduction line of induction should be minimum some contact with the moisture absorption layer of diaper, with realization to diaper moisture absorption layer status detection.The material of the conduction line of induction can be any compliant conductive media such as conductive filament, conductive paper, conductive fabric, conductive fiber or electrically conductive ink, the line of induction also can be distributed in the different local of diaper, different length and shape can also be arranged, and different line of induction number etc. is arranged, to specify/to determine different induction ranges.Also has opening 13 in the drawings; (the outer inner edge of diaper) is coated with antiseepage protective layer 18 on the opening; this protective layer can prevent that urine is in the opening part seepage on the one hand; can form an independently dry and comfortable space of ne-leakage with diaper outer 15 on the other hand, so that in this space, settle the urine-wet alarm apparatus.In order to realize this dry and comfortable space, antiseepage protective layer 18 must have suitable size, and the outer inner edge of its four limit and diaper is bonding, and mid portion swells a little and just can form corresponding space.Can see two dry and comfortable spaces (corresponding to the place ahead and the rear of diaper) up and down in the drawings, can in any one dry and comfortable space, settle alarm, to be fit to different prone positions, alarm can be installed in the place ahead of diaper when for example lying on the back, and alarm can be installed in the rear of diaper when prostrate, in order to avoid influence the comfortableness of its sleep.

Please refer to shown in Figure 5ly again, this is the alarm front view and the dorsal view of the embodiment of the invention.20a is the front view of alarm among the figure, and wherein 20 is the alarm body device, and inside comprises warning circuit, and 21 are the led state indication, and 22 are the elasticity folder.The front view that 20b is an alarm after removing the elasticity folder can have been found two contact electrodes 23 among the figure and since contact electrode be positioned at the elasticity folder below, so in the alarm front view shown in the 20a, can't see 23 existence.20c is the dorsal view of alarm.24 is a button among the figure, can make the switch of alarm power supply or make the usefulness of function test.Also have a reset key 25 in addition in the drawings, can make the usefulness that resets of alarm circuit.

Please refer to shown in Figure 6ly again, this is the alarm side view of the embodiment of the invention two and diaper then cutaway view and assembling sketch map.The diaper main body structure is the same with embodiment one among the figure, is made up of diaper skin 15, moisture absorption layer 16, internal layer 17 and waistline 11 respectively, and the difference main with embodiment one is that its dry and comfortable spatial structure/generating mode is different.In the present embodiment, the conduction line of induction 19 be stuck or silk-screen in the outer inner edge of diaper, and extend to outside the diaper from the waistline 11 of diaper positions such as (or the lower limb of diaper) enclosing, and in the place ahead of diaper or the rear form a pocket 12 (also be in the dry and comfortable space a kind of), alarm can pass through pocket openings (inlet) 13 agent set 20 is inserted within the pocket (as the direction of arrow among the figure), the elasticity folder 22 of alarm then is clipped in outward flange 14 places (extension of diaper skin 15) of pocket, alarm is fixed in the diaper pocket, simultaneously elasticity folder 22 can also apply an elastic force on contact electrode 23, makes contact electrode 23 and conducts electricity 19 of the lines of induction electric and contact more reliable.

In above-mentioned Fig. 2,3,5,6, the contact electrode of alarm depends on the agent set, in use agent set is positioned within the dry and comfortable space of independence of diaper, be sandwiched in diaper by elasticity then and outward will dry and comfortable spatial outward flange clamp fixing, and it is more reliable to make contact electrode and diaper conduct electricity being connected of the line of induction.In the actual product design, also the contact electricity design poling of alarm can be depended on the elasticity folder, the lead-in wire on the elasticity folder is introduced signal within the alarm body device then.In this case, the elasticity folder can be positioned within the dry and comfortable space of independence of diaper and the outward flange of diaper is clamped, and it is more reliable to make contact electrode and diaper conduct electricity contacting of the line of induction simultaneously, then can be positioned over as for alarm body outside the dry and comfortable space of diaper.This design characteristic is that the part that is built in the independent dry and comfortable space of alarm is less, and the part that exposes to outside the diaper is relatively large.Both then are similar technically, are the different designs and the form of expression of same technology.

In addition in above-mentioned Fig. 2,3,5,6, the elasticity of alarm is clipped on the independent dry and comfortable spatial diaper outward flange, in actual design, also some variations can be arranged, the line of induction that for example will conduct electricity in independent dry and comfortable space separates with the outward flange of diaper, in this case, the elasticity of alarm folder also can directly be clipped in to be implemented on the conduction line of induction and being electrically connected of diaper moisture absorption layer, and also plays certain fixation simultaneously.In order to make it more reliable with contacting of alarm contact electrode, can be on the conduction line of induction album leave rete or supporting layer, to increase the thickness and the intensity of the conduction line of induction.And above-mentioned all these variations also are within ultimate principle of the present invention.

Please refer to shown in Figure 7ly again, this is the alarm circuit schematic diagram one of the embodiment of the invention.Comprise sensing input circuit, high impedance input circuit and warning output loop among the figure, include a cell apparatus in addition, in order to make the alarm designs microminiaturization, present embodiment preferentially adopts button cell.The conduction line of induction of diaper is connected with the sensing input circuit among the figure, and further is connected to the signal input of input of high impedance input circuit.In the present embodiment,, adopt transistor Q1, Q2 to be combined into Darlington circuit, drive warning output loop/device by Q2 output then in order to increase the impedance of input circuit.Alarm output device can be light-emitting device, for example LED; Also can be sound-producing device, for example buzzer; Also can be wireless launcher, so that alarm signal sent to wireless receiver by emitter and make the usefulness of alarm indicator.In the present embodiment, under the dry and comfortable situation of diaper, present high impedance between the conduction line of induction, this moment, Q1 base stage no current flow through the alarm output device no-output; And when diaper urinated wet after, present Low ESR (because urine has electric conductivity) between the conduction line of induction, electric current flows out and crosses over the line resistance of the conduction line of induction from anode, enter the Q1 base stage by current-limiting resistance R2 then, directly driving LED, buzzer and emitter are done the output of reporting to the police after Q2 amplifies.Because the Darlington circuit that Q1, Q2 form has high input impedance, in order to prevent false alarm, can in circuit, increase resistance R 1 and eliminate the leakage current that may occur, can also regulate the sensitivity of reporting to the police and triggering by R1 simultaneously, the R1 resistance is more little, circuit is reliable more, but sensitivity is also corresponding low more.Also have a capacitor C 1 among the figure, the purpose of this electric capacity is to make alarm trigger Q1, Q2 and make light emitting diode shinny in short-term (or buzzer sounding) in powered on moment, the main usefulness of doing the energising test, and the while can also be eliminated the inductive interference of some human bodies.Also have a test button in addition among the figure, when button was pressed, the warning output loop was triggered, and whether this can be used for test battery electricity (or whether electric weight is enough), and whether alarm is normal etc.

Please refer to shown in Figure 8ly again, this is the alarm circuit schematic diagram two of the embodiment of the invention, is an improvement to schematic diagram one, and schematic diagram two has stronger function and higher reliability than schematic diagram one comparatively speaking.The core of Fig. 8 is a processor, or comprises the device of processor, for example single-chip microcomputer or special digital integrated circuit etc.Also adopted the sensing input circuit that holds the resistance formula among the figure, this circuit can detect not only whether urine is wet takes place, and can also detect the wet degree of urine, because it can produce a quantized input.The key of this circuit is the capacitor C 2 of input termination at the conduction line of induction, this capacitances in series is among conduction line of induction loop, battery can charge to this electric capacity by the line resistance of the conduction line of induction, when charging reaches a certain level, the sampling input circuit is triggered, the time that processor triggers according to charging judges whether diaper is wet by urine, and the wet degree of urine etc., because should the time and the line resistance relevant (being inversely proportional to relation) of the conduction line of induction, and the line resistance of the conduction line of induction be with to urinate the degree of wetting relevant.Also have a controlling of sampling loop among the figure, this loop is connected to processor and is subject to processing device control.In the time will urinating wet induction (sampling), processor makes capacitor C 2 discharge by diode D1 by controlling of sampling loop low level of output, and the input circuit of at this moment sampling is a low level.Processor stops (at this moment oppositely ending with the control loop diode in series) by a high level order of controlling of sampling loop output discharge more then, this moment, battery just can charge to capacitor C 2 by above-mentioned loop, till the sampling input circuit becomes high level and triggers processor.If diaper is in dry and comfortable state, the resistance between the conduction line of induction presents high impedance, and the charging rate of C2 is just very slow, and it is longer relatively that the input circuit of just sampling becomes the required time of high level from low level; If instead diaper is in wetting state, resistance between the conduction line of induction presents Low ESR, the charging rate of C2 just becomes than very fast, it is shorter relatively that the input circuit of just sampling becomes the required time of high level from low level, at this moment can confirm just that diaper is in wetting state, and the above-mentioned time is short more, shows that the wet situation of urine is serious more.Because the participation of processor is arranged, quantized signal input is achieved, and this makes the wet induction of urine of schematic diagram two compare with schematic diagram one higher accuracy and credibility.In the present embodiment, the LED light emitting diode is except that as the alarm output device, can also be as the usefulness of state indication, for example dodging green light is the dry and comfortable state of diaper, dodging red colored lamp is the diaper wetting state, dodging orange lamp (traffic lights are simultaneously bright) is low-voltage state etc., and these three kinds of states just can be realized with a dual-colored LED.

Alarm output device among the figure has also comprised an emitter, but this emitter transmitting radio alarm signal, make supporting with it wireless receiver can receive corresponding wireless alarm signal and do (long-range) output of reporting to the police, for example the relevant information of sound and light alarm or display alarm/emitter etc. at the wireless receiver end.Because emitter links to each other with processor, so processor can be by the digitized information transmission between emitter realization and receptor.Can also see that in the drawings a switch/test button is arranged, this button can be made the purposes such as transmission test of the on and off switch or the wireless transmitter of alarm.

Because alarm circuit of the present invention designs for power saving type, a button cell just can make the alarm work long time, therefore also can not consider the replacing problem of battery in actual applications.In this case, alarm can adopt sealed design, and (battery is disposable, do not have in the alarm to supply the parts of user's replacing), this design is the most safer, particularly on the market that the baby uses, can prevent from that tiny parts (for example button cell etc.) accident in the alarm from dropping out to be gulped down by baby's mistake and cause accident.

The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
