embodiment 1.
A kind of diaper monitoring detector bar, detector bar is provided with matrix and conduction band, and conduction band is printed in matrix, and matrix is set to hydrophilic non-woven, and conduction band is set to membrane resistance.
Conduction band is printed on the matrix of hydrophilic non-woven by this detector bar, even defecate when occurring when there being the liquid such as urine, liquid is instantaneously by this detector bar, due to the high water-permeability of hydrophilic non-woven, liquid is very fast through detector bar, capacitance between detector bar can sharply become the process then fallen after rise greatly by spontaneous experience electric capacity, therefore can be judged user whether defecation and defecation time length by the capacitance variation between detector bar.
This detector bar is used to be assembled to Excreta contact subject, carries out monitoring alarm by the capacitance variation measured between detector bar to the excretion situation of user.
Concrete, conduction band is set to film resistor, and the resistance of conduction band is not more than 10 kilo-ohms, and the width of conduction band is not more than 10mm.This optimum configurations makes detector bar can be applicable to conventional Excreta contact to carry out the monitoring of excretion situation.
It should be noted that, matrix also can be set to water repellency non-woven fabrics.Practice finds, when matrix is water repellency non-woven fabrics, liquid enters conduction band, and the electric capacity after liquid enters conduction band between conduction band returns and sharply increases.Because this diaper monitoring detector bar is in use coordinate the stronger diaper material of water absorbing capacity, liquid afterwards under detected bar below absorbed after, the electric capacity between conduction band reduces again.Therefore user whether defecation and defecation time length can be judged by the capacitance variation between detector bar.
Preferably, detector bar is also provided with protective layer, and protective layer is arranged at conduction band surface, and protective layer is set to hydrophilic or water repellency non-woven fabrics.The setting of protective layer can protect conductive paste, and avoids conduction band directly to contact skin.This diaper monitoring detector bar can be fixed in urine pants (or being called diaper), the diaper of traditional cloth material, diaper or other Excreta contact subject, also can be fixed on other device, carry out detection early warning.
For the ease of fixing with Excreta contact subject, adhesive tape can be set in the side away from conduction band of the matrix of detector bar, by adhesive tape, this Excreta detector bar be directly fixed on diaper, diaper etc.
This diaper monitoring detector bar can coordinate monitor, remote alarming system to carry out long distance monitoring.By defecation excretion situation on the Excreta contact that detector bar display is detected, and by the electric capacitance change situation between monitor test detector bar, relevant information is delivered to remote alarming system and is passed to second party by the wireless delivery port on monitor, remind it to carry out the replacings such as diaper, also can be checked the excretion situation of user by remote alarming system.
This diaper monitoring detector bar also can only coordinate with monitor, detects the electric capacitance change situation between detector bar, report to the police according to the electric capacitance change situation between detector bar by monitor, reminds nursing staff to change in time.
In sum, diaper monitoring detector bar of the present invention has the advantages that comfort is high, easy to use, accuracy of detection is high, detects the defecation excretion situation of user by it.
embodiment 2.
First be described, early warning monitoring diaper of the present invention does not have self-care ability person for child or old man etc. to use.Early warning monitoring diaper of the present invention should be understood to comprise diaper, diaper, diaper or other are for accepting the excremental Excreta contact subject of user defecation.
A kind of early warning monitoring diaper, as shown in Figure 1, be provided with urine pants body 100 and go along with sb. to guard him portion 200, the subsides skin inner surface of urine pants body 100 is provided with the detector bar 110 that two run through body internal surface.Detector bar 110 stretches out urine pants body 100, and the end that detector bar 110 stretches out urine pants body 100 is provided with the joint 120 for being connected with processor.
It should be noted that, the form of detection tabs 120 can be electric contact piece, intermediate plate, buckle-like or be plug-in unit etc., more convenient with plug-in unit.
It should be noted that, in the present embodiment, urine pants are provided with urine pants body and go along with sb. to guard him portion, also can only have urine pants body and not arrange the portion of going along with sb. to guard him.
It should be noted that, this early warning monitoring diaper at least needs to arrange two detector bars, can certainly be set to many detector bars, and as three or four, corresponding processor adjusts according to the facilities correspondence of detector bar.
Detector bar 110 is set to two, and two detector bars 110 are set in parallel.It should be noted that, the distance between detector bar can affect capacitance, and as general knowledge known in this field, the spacing accommodation processor according to detector bar is set to routine techniques means, does not repeat them here.Detector bar 110 is provided with matrix and conduction band, and conduction band is printed in matrix, and matrix is set to hydrophilic non-woven, and conduction band is set to membranaceous resistance.
Conduction band is preferably set to film resistor, better with carbon-base film resistance, and conduction band resistance is not more than 10 kilo-ohms, and the width of conduction band is not more than 5mm.
This early warning monitoring diaper, two detector bars 110 form electric capacity with urine pants body 100, have capacitance characteristic.When urine etc. appears in urine pants body 100, the electric capacity formed between urine pants body 100 and detector bar 110 can present capacitance variation according to the situation of liquid, just can judge the defecation excretion situation of user according to capacitance variation situation.Very little without electric capacity during urine between two detector bars in normality, and when user is urinated, urine enters urine pants instantaneously and soaks into detector bar 110, the capacitance moment between two detector bars 110 significantly increases.Because this detector bar 110 adopts hydrophilic non-woven, urine understands infiltrate detector bar 110 very soon, and detector bar recovers dry condition again, and the capacitance between detector bar 110 reduces very soon.Therefore, can judge according to the capacitance variation situation between detector bar whether user urinates, number of micturitions, the amount etc. of at every turn urinating.
A kind of processor structure coordinated with these early warning urine pants as shown in Figure 2, processor is provided with resistance R, MCU chip and display lamp, the two ends of resistance R are connected with the P1 pin of MCU chip, P2 pin respectively, detector bar 110 ground connection, another root detector bar 110 is connected with P2 pin, the P3 pin of MCU chip is connected with display lamp, and MCU chip is provided with for the blue tooth interface with mobile device wireless connections.During test, MCU chip applies a high level to resistance R to detector bar 110 by P1 pin, and for detector bar 110 charges, the P2 pin test electrode sheet of MCU chip charges to the time T of high level, and time conversion goes out capacitance size thus.Judge whether to occur defecation by the capacitance between test detector bar.When there is urine or stool, can there is significant change in capacitance, just can judge whether to there is defecation according to this change.Experiment finds, when only there is urine, the rate of change of electric capacity is higher than more than ten times, and when occurring defecating during particularly more dry stool, capacitance can occur sharply to change.The present invention adopts capacitance characteristic to detect, and has highly sensitive, and result is obvious, judges accurate feature.
This early warning monitoring diaper, adopt and arrange at the subsides skin inner surface of urine pants body 100 detector bar 110 running through body internal surface, detector bar 110 adopts mode of printing that slurry is printed in matrix, and therefore detector bar 110 can be firmly secured to urine pants body 100.No matter user in use appearance activity, roll, when the situation such as to grind, detector bar 110 all can not produce position and move, and can guarantee the excretion situation of accurate measurements user.
Because detector bar 110 is the subsides skin inner surface that strip runs through body, when the optional position of user in urine pants occurs that defecation is drained, all can detect in time.The defect avoiding sensor of the prior art can only detect certain part, causes installation requirement and the high defect of instructions for use.Therefore, as long as this early warning monitoring diaper is directly worn on user, do not need special mounting and use to note item, operation is very easy.
Because detector bar 110 matrix adopts hydrophilic non-woven, this base material has good water absorption and good water permeability.After urine enters, capacitance can become large instantaneously, and along with after hydrophilic non-woven absorbs urine gradually, and the good electrode cloth of water penetration recovers dry condition very soon, occurs that the capacitance short time reduces, the capacitance of the normal anuria state of convergence.By this Parameters variation, urination time length, total urination time and stool situation can be judged, control function of repeatedly pissing can be realized.Overcome monitoring diaper of the prior art once there is urine, can be low resistive state for a long time, cannot high-impedance state be recovered, the test function of secondary piss, three pisses cannot be realized.
Owing to adopting the film resistor be printed on hydrophilic nonwoven fabrics matrix as conduction band, therefore paste skin face contact with urine pants good, sensitivity is high.Drying stool under corresponding extreme case, capacitance there will be sharply significantly to be increased, and can realize the warning function to drying stool.Overcome the defect that urine pants of the prior art cannot realize carrying out drying stool test and monitoring.
This early warning monitoring diaper, adopts mode of printing that slurry is printed in matrix detector bar 110, has volume little, the feature that product is thin.
In sum, early warning monitoring diaper of the present invention has that comfort is high, easy to use, highly sensitive, accuracy of detection high, detected magnitude just can drain situation.
It should be noted that, the shape of detector bar is not limited only to the strip of the present embodiment, also can be set to curve or other shapes.Article two, the arrangement of detector bar is not limited to arranged in parallel, also can be other disjoint arrangement modes.
