Description
Related application
The application is partial continuous application, require that the applying date is on November 15th, 2010, be entitled as " electrolyte sensor using conductive elastomer ", application numbers is 12/946, the right of priority of the U.S. Non-provisional Patent application of 853, its full content is included in herein as a reference.
Technical field
Disclosure case relates to the use of conductive elastomer in electron device.Specifically, disclosure case relates to the electrode used in sensor.More specifically, disclosure case relates to the electrode detecting and include but not limited to use in existing electrolytical sensor in urine, sweat, blood, ight soil, saliva and spinal fluid.
Background technology
Existing fluid detection alarm is attached on user's clothes by safety pin, magnet or a special clip.In fact these methods not only have limitation, and cause various inconvenience to user.Although adhere to a fluid detection alarm can guarantee to hear warning when fully close on the clothes of user, if user is coated with woollen blanket or some other covertures with it, then the sound of reporting to the police is easy to become overcast.In addition, for guaranteeing that he/her sits up on fluid detection alarm, user must not sit up a position.Moreover safety pin and special clip may be easy to affect the comfortable and convenient of user, and magnet is not often enough to the powerful suction holding fluid detection alarm.
Method described by this part can be implemented, but the method not necessarily previously conceived.Therefore, unless otherwise indicated herein, the method described by this part is not the prior art of the claim of the application, and is not recognized as the prior art that this section comprises.
As everyone knows, conducting polymer and conductive elastomer have elasticity and electric conductivity, therefore use with the form of pad or seal.Comprise some useful performances as conductor, comprise shaping, corrosion resistance and sealing contact interface easily.But owing to being difficult to obtain the equally low resistivity of metal, its use as conductor can be limited.Conductive elastomer is generally made up of the silicon rubber introducing conduction carbon element or metallic particles.The resistivity of material changes with the content of conducting particles.
Being used for the treatment of enruesis with warning device by the sensor electrode that circuit is connected is news from nowhere.The electrolyte existed in urine realizes warning circuit by the gap between filling electrode or passage and closes, and indicates the situation occurring urinating thus.Most of existing electrode has one group of parallel both positive and negative polarity figure, otherwise is exactly linearly snakelike figure, so urine must contact bare wire, warning circuit is closed.Bare wire by gap in insulator can with urine contact, such urine just must enter both positive and negative polarity gap with trolley wire makes closing of circuit.
Existing electrolyte sensor is only limitted to close along the close clearance between two conductive plastics half districts, and each halfth district contacts with negative conductive element with the positive conductive element stretching into sensor main body from junction block respectively.Do not make closing of circuit because electrolyte may be present in plastics half district, and whole sensor surface is only made up of Liang Geban district, so this situation exists disadvantage.Disclosure case is not limited to this mode, by the positive and negative track Electrode connection of conductive elastomer of the present invention to respective wire terminal lead end, and conductive elastomer track electrode is all close to each other on whole sensor " track pattern ", thus make electrolyte can will make closing of circuit by contact simultaneously along any point on the positive and negative track electrode surface of the track pattern of the whole sensor surface that accounts for.This is a very important improvement, this is because to consider penis or other electrolyte source unpredictable in electrolyte position, so when in nervous system training, per a moment all will be striven for, electrolyte volume needed for each closed circuit or quantity should be low as far as possible, corresponding closing of circuit should be rapid as far as possible, to realize effective treatment.The example of sensor track pattern is as shown in Fig. 2 A-2K.
Another advantage compared with existing solution uses thermoforming mounting rail apodized electrode.Described thermoforming elastic body electrode is significantly larger than existing colorimetric sensor films or P.e.c. more firm, can tolerate user and dress and spend the night, also can tolerate the degraded of the corrosive substances such as urine.Dedicated printed circuit board on solid inflexibility carrier is used to detect " humidity sensor " at catheter position.This circuit can not tolerate the corrosivity effect of urine and the amalgamation used continuously of spending the night of wearer.
The sensor being used for detecting the electrolyte that exists in material beyond urine used runs with the principle forming bridge joint between sensor electrode, perform the function of closed circuit thus, for different form of therapy is offered help, specifically depend on the body system of content that sensor detects, upstream electronic device and process.The example of other object comprises the ight soil in the blood and spinal fluid leakage and perception diaper detecting catheter position.These examples do not get rid of other purposes, but some application of some conductive elastomers used in sensor electrode will be described, and which demonstrate conductive elastomer electrode in existing solution, done general improvement, particularly because electrolyte can contact reliability conductive elastomer track electrode (but particularly because electrolyte can make the metal wire contact of electrolyte and distribution or need enough volumes and directivity to be connected plastic electrode half district) is generally improved than existing solution because a lot of reasons.
