The detection disc 6 is made of high-temperature-resistant transparent materials, the front side face and the rear side face of the detection disc 6 are respectively pasted with an opaque shielding film 10, a notch 101 is formed in the shielding film 10, and the notch 101 is used for observing the color change condition of the allochroic silica gel in the groove 62 communicated with the detection tube 7.
The specific implementation process is as follows:
when the sector gear 83 is ready to mesh with the first gear 84, the detection pipe 7 is not in communication with the grooves 62, but the connection port 64 is in communication with one of the grooves 62, i.e., the state shown in fig. 3, and the second gear 65 is in relation to the incomplete gear 85 as shown in fig. 2.
When beginning to detect the moisture in the patient oral cavity, motor 81 is in the starting condition, sector gear 83 rotates to mesh with first gear 84, gear section 86 and the meshing of second gear 65 of the incomplete gear 85 on the jackshaft 82, make carousel 61 rotate, rotate the back, connector 64 still communicates with the recess 62 that originally communicates, simultaneously detecting tube 7 also communicates with this recess 62, when sector gear 83 drives jackshaft 82 and rotates, convulsions are opened to convulsions unit 9, be convenient for take out the recess 62 through convulsions unit 9 with the gas in the oral cavity through detecting tube 7.
When the first gear segment 86 is separated from the second gear 65, the rotation of the turntable 61 is stopped, but the air draft unit 9 continues air draft (namely, the negative pressure blades 92 in the negative pressure shell 91 continuously rotate), so that air in the oral cavity of the patient is pumped into the groove 62 through the detection pipe 7 through the pipeline and the groove 62, when the moisture content in the air pumped out of the oral cavity is high, the color of the allochroic silica gel is changed into pink, and along with the air draft, more and more allochroic silica gels are gradually filled in the groove 62; if the silica gel colour that discolours does not change basically, then it is few to mean moisture in the patient's oral cavity, needs carry out the moisturizing, and medical personnel just can judge directly perceivedly that the patient is in the state of lacking water when observing test tube 7 and recess 62 intercommunication and the silica gel that discolours not discolour, and whole process does not need artificial data collection, and it is convenient to detect.
When the sector gear 83 causes the second gear segment 87 to mesh with the second gear 65, the second gear segment 87 causes the rotating disc 61 to rotate, the groove 62 for detecting oral cavity moisture rotates counterclockwise away from the detecting tube 7, and meanwhile, the detecting tube 7 is blocked by the rotating disc 61 again to return to the state shown in fig. 3 to prepare for the next detection.
After the sector gear 83 drives the first gear 84 to rotate for one turn, the sector gear 83 continues to rotate until the sector gear 83 rotates again to be meshed with the first gear 84, and then the next oral cavity moisture detection can be started, so that the timing interval detection of the oral cavity moisture is automatically realized through the sector gear 83.
To using the allochroic silica gel that has discoloured, can utilize heater strip 63 to heat allochroic silica gel for moisture on the allochroic silica gel disperses through the intercommunicating pore on the circular arc groove, and allochroic silica gel resumes to the dry state, and the follow-up allochroic silica gel with in the recess 62 of being convenient for continues the detection of oral cavity moisture, makes the material can cyclic utilization.
Example two
With reference to fig. 5 to 8, the second embodiment is improved based on the first embodiment as follows: the oral cavity moistening device comprises a spraying instrument 1 and a spray pipe 2, a water tank 11 and a spray head are installed on the spraying instrument 1, the upper end of the spray pipe 2 is inserted into the spray head of the spraying instrument 1, and the lower end of the spray pipe 2 is inserted into the oral cavity of a human body; install color code photoelectric switch 12 on the carousel 61, color code photoelectric switch 12 electricity is connected the switch of spraying appearance 1, and color code photoelectric switch 12 is used for putting through spraying appearance 1 when sensing that the color of color changing silica gel does not change.
With reference to fig. 7 and 8, a baffle 66 is bonded to an opening of the groove 62, the baffle 66 is used for blocking the color code photoelectric switch 12 (so that the color code photoelectric switch 12 cannot detect color-changing silica gel), a third gear segment 88 is arranged on the incomplete gear 85, the first gear segment 86, the third gear segment 88 and the second gear segment 87 are sequentially distributed counterclockwise, and the third gear segment 88 is used for making the baffle 66 on the groove 62 not block the color code photoelectric switch 12 any more.
The specific implementation process is as follows:
After allochroic silica gel accomplished the detection to oral cavity moisture, color mark photoelectric switch 12 loses the sheltering from of baffle 66 under the effect of gear section three 88, and then detects allochroic silica gel's the condition of discolouing, when detecting allochroic silica gel still is blue, it is few to explain the moisture in the oral cavity that just detects, the patient needs moisturizing, color mark photoelectric switch 12 makes atomizer 1 the vaporific hydrone of blowout this moment, vaporific hydrone enters into the patient through spray tube 2 internal, the completion is supplemented to patient's moisture.
When the second gear segment 87 is engaged with the second gear 65, the rotary plate 61 is rotated to prepare for the next detection, and the color patch photoelectric switch 12 is also shielded by the baffle 66 again.
On the basis of embodiment one, this embodiment two had both accomplished the detection to patient's oral cavity moisture, had realized again that the automatic judgement patient lacks water to in time adopt color mark photoelectric switch 12 and spraying appearance 1 to in time moisturizing to the patient in the time of lacking water, further improved degree of automation, reduced medical personnel's work load, also made patient's lack of water obtain in time solving.
EXAMPLE III
