The detailed description of preferred embodiment
The present invention proposes the more durable probe or the teat of eardrum infrared thermometer.No. 5088834 United States Patent (USP) by people such as Howe application described a kind of eardrum infrared thermometer, by measure the heat energy of eardrum radiation in the duct by probe (preferably putting health, disposable overcoat), can be rapidly and the temperature of accurately reading human body.When with the combination of this thermometer and probe of the present invention, for example when 3 feet height lands, thermometer can bear damage physically and break, its accuracy and precision and free of losses.The present invention has obtained this result by structure and the composition that changes some probe elements.
Referring to Fig. 2 (a) and 2 (b), catoptron 200 imports the Infrared survey element of probe the optimum position with respect to eardrum in duct.Catoptron 200 also can support and accommodate other probe element.As seen, catoptron 200 is that the cross section is the shape of infundibulate and radial symmetry mostly from preferred embodiment shown in Fig. 2 (a) and 2 (b), from the inside surface 208 of catoptron seal 202, cylindrical shell 204 (or waveguide) and window 206 is set with inwardly going forward one by one.Catoptron 200 of the present invention directly is engaged to the preceding piece 210 of thermometer shell 300, piece 210 before preferably screwing in by screw thread 212.Catoptron 200 is installed on the preceding piece 210, its preferably a kind of firm metal support, 214 provide additional rigidity for popping one's head in, making pops one's head in when thermometer lands clashes into the shell 300 of the mechanical energy guiding thermometer that is produced with the floor, rather than absorb by it, or be delivered to cylindrical shell 204 and window 206 via catoptron by the distortion of catoptron 200.Cylindrical shell 204 and window 206 are sensing units, and its aligning and integrality are critical for the normal function of probe 214 and thermometer 302.
In order to increase the rigidity of probe, catoptron 200 of the present invention is made such as glass polycarbafil (being commonly referred to glass fibre) by more hard material.In preferred embodiment, rigidity and hard catoptron 200 are made by the polycarbonate that polyimide (polyetherimide) that strengthens with 20% glass (sold by General Electric Co. Limited, trade mark is called " ULTEM ") or 30% glass strengthen.Find respectively that now these two kinds of materials are stood teat and highly at first fallen hard place plate surface such as on the ceramic tile from four feet and 3 feet repeatedly.Even " land " afterwards repeatedly repeatedly this, probe 214 of the present invention also can continue to work as before, is not having any accuracy and loss of significance aspect infrared acquisition and the measurement.
Because cylindrical shell 204 or infrared waveguide are responsive especially to environment temperature, preferably with it with catoptron 200 heat isolation and sealed.Hot isolation can guarantee that the environment thermal energy (being its temperature) of catoptron 200 can not influence the Infrared survey of being carried out.In addition, seal 202 can prevent that liquid such as cleaning solution from flowing to the outside of waveguide, and prevents to reduce because of evaporative cooling makes performance.Except having these functions, seal 202 of the present invention also provides a kind of additional structural function simultaneously, can 214 provide better protection to popping one's head in when falling.
For making probe 214 and thermometer 302 operate as normal, the aligning of infrared emission window and integrality are crucial.In order further to protect window 206 to avoid breakage and misalignment, window 206 is thicker in usually to increase durability.In addition because its whole placing in the cylindrical shell 204, away from the wheel rim of catoptron 216, thus under the situation that teat at first lands, can by the wheel rim of catoptron 216 and cylinder lateral wall 218 both and around seal 202 protect window 206 jointly.By window 206 being bonded in the cylindrical shell 204 with bonding agent, during falling, keep the gas-tight seal between cylindrical shell 204 and the window 206, can provide additional protection for it.Preferably, this bonding agent is injected into via two side openings forms gas-tight seal in the cylindrical shell.This mode that window is installed provides excellent protection for window 206, can not clash with the part light path.Preferred embodiment adopts a kind of bonding agent that passes through the urethane groups single component of heating or ultraviolet light photopolymerization.The unhardened viscosity of this bonding agent is 300 centipoises.During curing, bonding agent has 160,000psi elastic modulus, 3,500psi tensile strength, the elongation of 30% crash rate and 85 Shore D level hardness.A kind of suitable bonding can have been bought from Norland Products company at present, and production number is Norland 121.
Thermometer has shell 300 to accommodate the relevant parts of this device.By Jacob Fraden, No. 4797840 United States Patent (USP) of Ph.D. application described the function aspects of non-sonde-type thermometer elements in more detail, but can only do simple description here.Housing 300 is supporting preceding piece 210 and is comprising one away from the sensor on the cylindrical shell of window 206.Sensing system can comprise thermoelectric pile type and thermoelectric element.This sensor is connected to a processor, in order to infrared data is converted to high-quality temperature reading.This temperature reading is fed to visual display unit in order to treatment or other purposes.Housing 300 preferably is shaped to and is easy to catch and supports an exercisable switch, and announcement apparatus reads out the infrared energy from eardrum.
Obviously, without departing from the spirit and scope of the present invention, those skilled in the art can also make various conversion and improvement to said structure.But scope of the present invention is limited by claims.
