Fig. 8 A～8B shows an embodiment of the hydration sensor 450 that can use more than once.The detector arrangement 454 that is used for this detector 450 comprises a timer 456, one switches 458, and a power supply 460.This detector arrangement also comprises a cavity 462 and a hinged door, holds a dank material 452.For example, this dank material is the glass fibre cloth.In cavity 462 inside some electric contactors 470 are arranged, be positioned at structure 454 first end 466 near.Catalyst 470 can be on the surface of a printed circuit board (PCB).Catalyst 470 is spaced apart from each other, and the resistance value between its preceding two catalysts is used to start timer 456, and the resistance value between the second and the 3rd catalyst is used to stop timer 456.Interval between any two catalysts for example, can be 0.010 inch.
In order to measure the amount of drinking water level, a detecting element 452 places in the cavity 462.Then close door 464, and detecting element 452 touches catalyst 470.As shown in Fig. 8 B, user inserts Sublingual with hydration sensor 450, and saliva is inhaled (wick) and come up.Near catalyst 470, can there be an elastomer or a little spring to make it near catalyst 470 under the door 464 with pinch detection element 462.In one embodiment, the remaining edge of catalyst 470 ratio sensor structures (for example 474) is more near first end 466.In one embodiment, in the structure 454 multi-disc detecting element 452 is arranged.This element 452 can be roll, and this roll or a plurality of can add sawtooth.
In another embodiment, this detecting element can use once again, such as being suitable for continuous use.In one embodiment, the detecting element that can use once again comprises a passage aisle (or pipe), and capillarity can be brought saliva up along passage.In another embodiment, pump is taken out effect and also saliva can be brought up along passage.Fig. 9 shows an embodiment of an amount of drinking water detecting element 500 that can use once again.This passage is a hollow pipe 502, and wherein liquid can be along little internal diameter, such as about nine Mils cun or five Mils cun, drinks up.This pipe can be by glass, nylon, poly carbon, acrylate, hydrophilic (trend by water-wet), or its inner surface is made by the coated material of the material of water-wet with tending to.Detecting element 500 comprises the number of metal catalyst, as 504,506 and 508, upwards is spaced apart from each other along pipe 502.First, second and third line 514,516 and 518 connects with first, second and third catalyst 504,506 and 508 separately.
In order to determine individual amount of drinking water level, as shown in Figure 9, the part of hollow pipe 502 places mouth, and the resistance between the catalyst is measured.
Can there be diverse ways to remove saliva from this pipe.A kind of method is based on a mechanical pump.Figure 10 A shows the hydration sensor that can use once again 550 based on a mechanical pump 552.Figure 10 B shows some assemblies of detector 550 inside.Detector 550 comprises a passage or the hollow pipe 554 with little internal diameter, and some electric contactors are wherein arranged.From the line of catalyst is the resistance that is used for measuring (between oramong) between the catalyst, and this is by using the printed circuit board (PCB) 556 with a microcontroller 558 to finish, and this printed circuit board (PCB) is by an accumulator 560 power supplies.In one embodiment, the circuit on this plate 556 comprises that those are shown in the circuit among Fig. 7 A or the 7B.
In order to remove the saliva in the pipe 554, user can be pressed mechanical pump 552, and it can be the bellows 562 with spring 564, so that saliva is discharged from managing 554.In one embodiment, surpassed specific predefined point when bellows 562 push downwards, switch 566 is triggered to measure the resistance value between the catalyst.Depend on suction along pipe 554 flow velocitys to the saliva of getting on.Suction depends on the vacuum that expansible bellows are created, the viscosity of the saliva in the diameter of pipe and the user mouth.Water content is inversely proportional in viscosity and the mouth.The pressure that is produced by vacuum can be constant, and for example, via the spring that will have similar constant elastic force, or hollow rubber ball (as eye dropper ball) is as bellows.Perhaps the pressure of being created can be measured by the vacuum-pressure detection device in the bellows.
In one embodiment, the upper surface of bellows has a hole.The finger of extruding bellows 562 covers this hole to release air.When bellows 562 expanded, this hole was exposed to air is sucked back in the bellows 562.If there is competent size in this hole, just can not produce vacuum.The viscosity that depends on the saliva in the user mouth along the flow velocity of pipe 554 salivas that make progress.
In one embodiment, after saliva is removed, also have the opening part that a droplet saliva may remain in pipe, available cloth is wiped.
In one embodiment, thus the detector among Figure 10 B comprises that also an interface such as standard USB interface are so that be uploaded to another equipment analytical data with measurement result.
In one embodiment, an amount of drinking water detecting element directly is linked to user or is linked to the wearing on the thing of user, such as eyes, medicated cap or clothes, is used for the mouth of the Guan Ze of saliva at user.In one embodiment, detecting element can be the saliva of the interval continuous measurement user that is predetermined.
In one embodiment, detecting element can wirelessly or by circuit be connected to another equipment, the portable set entrained as user.This portable set can transmit drinking-water and indicate to detecting element, and perhaps this portable set can directly provide indication to user.This portable set can wirelessly transmit the relevant information of measurement result and give remote equipment or platform in one embodiment.But remote stations continuous monitoring and analyze the amount of drinking water level of user, and send signal to portable set for user.
This portable set or devices in remote electronic based on information and other information about weather, can advise how many user should drink at next moisture/liquid supply point.This suggestion also can be depending on the moisture/position of liquid supply point and the orientation of user.These positions can be determined by the entrained GPS equipment of user.
Figure 11 A-11D is showed in an embodiment of the hydration sensor that can use once again 600 at least one tooth in the user mouth.When user was stung detector rightly, this detector can be removed the saliva in pipe.Figure 11 B-11D shows vertical view, side view and the rearview that can sting detector 600 separately.This can sting the pipe 608 that 602, one at seat that detector 600 comprises a U-shaped allows saliva enter, bellows 604 (can sting bellows and remove saliva in the pipe), and one makes it to be shaped being fit to the loam cake 606 of user upper teeth, and a packing 610.Electronic device is reliably stung bellows 604 or is pushed away an on/off button with tongue and activated.In one embodiment, this strap has wireless transmitter.
The hydration sensor that can use once again can comprise that an electromechanical pumps is to remove saliva in passage or pipe.Figure 12 shows so embodiment 630.Three electric leads 634,636 and 638 to micro controller unit 632 can be from three leads 514,516 and 518.Figure 13 shows the step of the electronic device that uses the hydration sensor that can use once again, the high or logic (logic) 1 of 1 expression wherein, and 0 expression low or logical zero.Waiting step 674 can depend on the frequency that micro controller unit 632 is measured.The pressure of time T and vacuum pump and the viscosity of saliva are proportional.
In a use vacuum pump pulls saliva along pipe embodiment, this pipe or passage use hydrophobicity (hydrophobic) material, and as polypropylene or polyethylene, it can easilier be cleaned and be dry so that use afterwards.
In one embodiment, embodiment 630 does not comprise vacuum pump 642, and the viscosity of time T and saliva is proportional.
