Description
The utility model relates to a kind of detector cover cap, particularly relates to the deserted cover cap of a kind of ear thermometer device use.
Among the medical diagnosis on disease process, clinical thermometer often provides great help.In all measuring points, the temperature of ear-drum more can be represented the temperature of body interior than the temperature of oral cavity, rectum or oxter.We can measure the temperature of ear-drum by detecting the infrared radiation of radiating from ear-drum in the duct.Use the required Measuring Time of infra-red thermometer also shorter when taking temperature in addition, for patient.Therefore, the use of infrared ear temperature meter is more and more general.
As shown in Figure 1, in order to measure the infrared radiation in the duct, use the timing of ear temperature one microscler detector 11 must be stretched in the external auditory meatus.The infrared radiation of sending from ear-drum is by the window 12 of the distal openings 13 of detector 11, arrives sensor in the thermometer via the guiding of wave guide then.Yet when using this thermometer to measure different patients' body temperature, pollute probably and the infection of disease.In order to prevent this from occurring, all be with a detector cover cap outside the detector of these thermometers, after using each time, abandon.Except the protective effect of health aspect, this detector cover cap also should possess following function simultaneously.At first, this detector cover cap is necessary for the penetrable formula of infrared ray, or has at least a part to can be used as the use of infrared ray window.Secondly, this detector cover cap must be able to allow detector smooth-going and make patient enter in the duct with feeling comfortably cool.
For reaching this purpose, existing multiple detector cover cap is devised.For example Okha reins in that (it is a kind of by the made deserted detector cover cap of the penetrable formula film of harder tubular body 22 and infrared ray 21 that O ' Hara) waits the people to propose in the patent of United States Patent (USP) number 4662360.The penetrable formula film 21 of this infrared ray be adhered to tubular body 22 than far-end and with its sealing.The penetrable formula film 21 of this infrared ray is to be made by infrared ray penetrable tygon or polypropylene screen as the usefulness of infrared ray window, and thickness is between 12.7 to 25.4 microns (0.0005 to 0.001 inch).As shown in Figure 2, film 21 is adhered to the periphery of the distal end portion of tubular body 22, can form seam 23 at its edge.If this seam 23 protrudes in the surface of detector cover cap, patient is felt under the weather.On the other hand, if the adhesion of film 21 and tubular body 22 is firm inadequately, film even may drop in duct.
With reference to Fig. 3, Fu Laideng people such as (Fraden) proposes the another kind of detector cover cap of protecting the thermometer detector with convolution sheath 33 in the patent of United States Patent (USP) number 5163418.This sheath is made by the penetrable formula film of infrared ray of a slice thickness about 25.4 microns (0.001 inches), and the blind end of this sheath constitutes Infrared window oral region 31.Be adhered to around the convolution sheath 33 at the bottom of the cyclic group on 32, this substrate 32 be designed to can with the driving fit of thermometer detector.Infrared window oral region 31 is positioned on the approach of the infrared radiation that ear-drum sends.The shortcoming of this detector cover cap is for when this detector cover cap enters in the duct, and the pleat trace that probe cover covers scrapes the duct epidermis can make us very uncomfortable, and sheath itself can send suitable noise when being squeezed.In addition, the Zhe that wrinkles may appear in Infrared window oral region 31 when being contained in this detector cover cap on the detector, causes ultrared stray radiation (stray radiation) and influences the accuracy of measured temperature.
He Wei people such as (Howe) has also proposed another detector cover cap in the patent of United States Patent (USP) number 5088834.With reference to Fig. 4, this integrally formed detector cover cap has the sheath 43 and a substrate 42 of a truncate capitiform, and sheath 43 and detector coincide mutually, and substrate 42 be bonded on sheath 43 proximal around, be used for sheath is fixed on the detector.Sheath 43 is all made by the penetrable formula material of infrared ray, the thickness convergent of its distal portion, and make that window 41 thickness that are positioned at distal end portion are the thinnest, between 25.4 to 12.7 microns (0.001 to 0.0005 inch).Infrared radiation can enter in the thermometer through detector by this window 41.Because the thickness of sheath is to be tapered to 12.7 microns (0.0005 inches) from 762 microns (0.03 inches), the control of quality is comparatively difficult in manufacture process.And manufacturing equipment is through the use of segment length's time and after aging, changing may appear in the thickness of window 41.Thicker window can absorb more infrared ray, and thin window then breaks easily.In addition, the window 41 of wrinkle Zhe can cause ultrared stray radiation and influence the correctness of measured temperature.
Therefore, one of the purpose of this utility model is to propose a kind of ear thermometer device cover cap of improvement, and it has smoothly and the infrared ray window of thickness homogeneous, can not influence the accuracy of measured temperature.
Another purpose of the present utility model is to propose a kind of ear thermometer device cover cap of improvement, can't make patient do not feel like oneself when the detector that this cover cap is housed stretches into duct.
