Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A sinusitis detecting device, as shown in fig. 1 and 4, comprises an oral optical component 1 for insertion into a patient's mouth, a light source 2 connected to a distal end of the oral optical component 1 via an optical fiber 21, and a light source 2 for transmitting light from the light source 2 to the oral optical component 1 to diffusely illuminate soft tissues at the top of the patient's mouth, such as a maxillary sinus region; the light source 2 is provided with a detector 3 on one side, the detector 3 is used for receiving optical signals which pass through the patient's nasal sinuses and leave the patient's tissues and converting the optical signals into electrical signals, meanwhile, the detector 3 is also electrically connected with an analyzer 4, and the analyzer 4 carries out data comparison, analysis and grading reference according to the electrical signals provided by the detector 3 so as to obtain a diagnosis data report. Since light can easily travel through the sinuses to the patient's facial tissue, and intra-sinus fluids due to infection can reduce the intensity of transmitted light and alter the pattern of transmitted light, the health of the sinuses can be inferred by the physician from the images taken by the detector 3 and processed by the analyzer 4 for diagnostic purposes and to monitor the progress of the treatment. Therefore, in order to accurately measure the health condition of the sinuses, the above oral optical member 1 is first inserted into the oral cavity of the patient, in which a light transmission point is placed toward the palate region below the maxillary sinus, the present oral optical member 1 is pushed by the patient or doctor to be in close contact with the sinus portion at the top of the oral cavity, then the light source 2 is turned on, thereby transmitting a light signal to the light transmission point of the oral optical member 1 through the optical fiber 2, the soft tissue at the top of the oral cavity of the patient is illuminated in a diffused manner, then the detector 3 is allowed to perform image acquisition at a fixed time node, i.e., light transmitted through the patient's sinuses and cheeks is captured, and this optical signal is converted into an electrical signal, finally the analyzer 4 performs data comparison, analysis and hierarchical reference according to the electrical signal provided by the detector 3, i.e., the absorption spectrum of the fluid or biofilm in the sinuses is separated using a tissue spectroscopy technique (e., diffusion spectroscopy), and processed by various imaging algorithms to form an imaging database, allowing a doctor to identify the degree of hydrops and inflamed mucosa swelling in the sinuses by comparing with target data to obtain a diagnostic data report.
As shown in fig. 3 and 4, the surface of the oral cavity optical component 1 is formed with an arc surface matched with the top of the oral cavity of the patient so as to conform to the change of the palate curvature of the oral cavity and effectively reduce the illumination error. Simultaneously, because left upper jaw sinuses and right upper jaw sinuses are parted by nasal cavity and nasal conch, when oral cavity optical component 1 was placed at the central line of nasal cavity below, the light field produced asymmetric illumination pattern easily, light through the diffuse emittance is partial to one side or opposite side very easily, so for solving this problem, it has the through-hole 11 that the symmetry set up and correspond with patient's sinuses position to open on oral cavity optical component 1's arcwall face, the diameter of through-hole 11 is 2mm, carry out optical transmission through-hole 11, thereby avoid the slope of oral cavity optical component 1 after stuffing the oral cavity to place, with this asymmetric irradiation of preventing.
As shown in fig. 3, a glass plug 13 is disposed in the through hole 11, and the glass plug 13 is disposed to prevent liquid in the oral cavity from penetrating into the oral cavity optical component 1, causing unnecessary errors, and at the same time, light emitted from the light source 2 can illuminate soft tissues at the top of the oral cavity of the patient in a diffused manner, thereby reducing the illumination uncertainty and variability occurring when the oral cavity optical component 1 is in direct contact with the top of the oral cavity.
As shown in fig. 3, a handle 14 is provided at one end of the oral optical component 1 near the optical fiber 12, so that the patient or doctor can insert the oral optical component 1 into the oral cavity and push the oral optical component 1 to be in close contact with the sinus part at the top of the oral cavity; in addition, a shielding plate 15 for preventing light from overflowing from the oral cavity of the patient is arranged between the handle 14 and the oral cavity optical part 1, and meanwhile, after the oral cavity optical part 1 is accurately positioned, the shielding plate 15 is just positioned at the outer side of the lip for blocking the light leakage position, so that the positioning effect is achieved.
As shown in fig. 4, the light source 2 includes a mixed light source and a dual wavelength light source, and a white diode, a light emitting diode or a laser may be used as the light source 2 to guide light to a specific region of the paranasal sinus for detection. In this embodiment of the present invention, the light emitting diode is preferably capable of generating light in the NIR spectrum, the wavelength range is 650nm-1050nm, and the type, wavelength and number are not limited. Since white light covers all relevant wavelengths from 600 to 1000nm, all relevant information about the sinusitis disease can be obtained, on the other hand at discrete wavelengths the intensity is much higher and the resulting image quality is higher. Therefore, in a multispectral imaging setting, the commonly used biomedical spectroscopic method can be used to quantitatively determine endogenous chromophores and fluorophores (i.e., fluids in the sinuses), and switch between white light and dual wavelength light, using the data of multiple measurements for comparison, resulting in better imaging quality and the ability to reject the effects of ambient light on the image.
As shown in fig. 4, the detector 3 is a camera, the type of camera is not limited, and in some embodiments, the camera is wifi-compatible, and automatically transmits data, for example, a mobile device with a built-in camera can be used for image capturing, displaying and storing. In addition, the camera is configured to capture images at all wavelengths and has a high ISO setting, enabling fast acquisition of data.
When a bare LED array light source directly contacting the palate of the oral cavity is used, since one part of the LEDs is in close contact with the tissue of the paranasal sinus of the human body and the other part is not in close contact with the tissue of the paranasal sinus, the degree of clarity of the illumination image may vary depending on the location position of the illuminator, and thus it is difficult to generate a uniform square when the bare LEDs are used, so that the arrangement of the oral optical member 1 is necessary. Meanwhile, when the light source 2 is arranged inside the oral cavity optical component 1, the structure cannot provide enough safety guarantee between the mouth and the electronic element, and the light source 2 can generate heat transfer after being opened for a long time to influence the detection experience of a patient, so that the light source 2 is arranged outside the body as shown in fig. 1, and optical signals are transmitted through the optical fiber 21, thereby effectively solving the problem.
As shown in fig. 4, the analyzer 4 includes an image selecting section 41 that selects any one of the output signals obtained by the m detectors 3 as a reference image signal and selects the output signal obtained by the m-1 detectors 3 as a superimposed image signal; an image synthesizing section 42 for superimposing the m-1 superimposed image signals and the reference image signal; an image difference section 43 that separately images the m-1 superimposed image signals from the reference image signal; and an analysis unit 44 for collecting data from the image synthesis unit 42 and the image difference unit 43 and performing statistical analysis to obtain a diagnostic data report. In this embodiment of the present invention, m is 4, that is, when the exposure is not performed, the light source 2 uses white light, the light source 2 uses light with a wavelength of 650nm, and the light source 2 uses light with a wavelength of 1050nm, the detector 3 performs image acquisition at a fixed angle at a fixed time node, and then the important regions are superimposed and separated according to a pixel method or a region analysis method, so that the illumination pattern of the patient can be obtained to clearly see the result of the fluid in the sinus. These pattern shapes may indicate the patient's anatomy and physiological blockage, e.g., the thin bone layer may transmit more light at the zygomatic bone, the image is shown thicker, the light field intensity of the maxillary sinus of the underlying effusion is weaker, and the fluid or biofilm stacking in the maxillary sinus may change the shape of the illumination pattern, thereby enabling a fine quantitative comparison between normal and diseased sinuses based on typical isoparametric shape patterns.
As shown in fig. 1 and 2, the main unit 5 is disposed outside the light source 2, the detector 3 and the analyzer 4, and the diagnostic data display interface 51 and the operation keys 52 are disposed on the side surface of the main unit 5, so that the nasosinusitis detection device is more portable, highly applicable, widely popular, and simple to operate, and can detect nasosinusitis at any time without special diagnostic conditions and operation training.
The invention also discloses a use method of the nasosinusitis detection device, which comprises the following steps:
