Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to an irrigator and application thereof in ear canal treatment. Background Art

[0002] In the ENT clinic of the hospital, there is a great demand for external auditory canal flushing. Earwax, foreign bodies in the external auditory canal, fungal otitis externa, suppurative otitis media, middle ear cholesteatoma, etc. all require external auditory canal flushing.

[0003] An ear canal irrigator is a medical device used to clean the ears. Its working principle is based on the principle of air pressure change and water flow dynamics. An ear canal irrigator usually consists of a handheld nozzle and a water tank. When the user inserts the nozzle into the ear canal and presses the button, the water in the water tank enters the ear canal through the nozzle. At the same time, the nozzle generates a small air pressure change, which can help flush out dirt and earwax in the ear canal.

[0004] However, most of the existing ear canal flushers are syringes connected to blood collection needles. This flushing method has some disadvantages. First, the dirt in the ear canal is generally attached to the inner wall of the ear canal. Due to the small inner diameter of the ear canal, it is difficult to adjust the angle. Directly using a syringe and a blood collection needle to flush the medicine into the ear canal is not only difficult to flush off the dirt attached to the inner wall of the ear canal, but also easy to damage the eardrum. Secondly, if a plurality of liquid outlets are opened on the side wall of the blood collection needle towards the inner wall of the ear canal, on the one hand, due to the large number of liquid outlets, the pressure of the sprayed medicine is small, which is not conducive to impacting the dirt. On the other hand, the simultaneous discharge of liquid from multiple liquid outlets will cause a large amount of medicine to enter the ear canal in an instant, causing discomfort to the patient and increasing the frequency of applying the medicine. Summary of the invention

[0033] See also Figures 1 to 7 In an embodiment of the present invention, a flushing device comprises a needle tube 1 and a liquid pushing column 2 slidably matched with the needle tube 1, one end of the needle tube 1 is movably sleeved with a sleeve 3, and a side wall of the sleeve 3 away from the liquid pushing column 2 is provided with a liquid outlet 4;

[0034] A rotating propulsion assembly is provided between the needle tube 1 and the liquid pushing column 2, and the sleeve 3 is connected to the rotating propulsion assembly. Under the action of the rotating propulsion assembly, the sleeve 3 will extend into the ear canal while rotating, so that the cleaning liquid in the needle tube 1 rotates and rinses the inner wall of the ear canal through the liquid outlet 4;

[0035] A sealing assembly is provided between the needle tube 1 and the sleeve 3 , and the sealing assembly is used to enable the cleaning liquid to be quickly discharged from the liquid outlet 4 and to prevent excessive cleaning liquid from filling between the needle tube 1 and the sleeve 3 .

[0036] In this solution, during the process of the liquid pushing column 2 pushing the medicine into the needle tube 1, the sleeve 3 will rotate and extend into the ear canal under the action of the rotating propulsion component, so that the cleaning liquid in the needle tube 1 can rotate and rinse the inner wall of the ear canal through the liquid outlet 4, which not only ensures the impact force of the cleaning liquid on the inner wall of the ear canal, but also avoids a large amount of medicine from entering the ear canal in an instant, thereby reducing the frequency of medicine application; in addition, the provided sealing component can enable the needle tube 1 and the sleeve 3 to always maintain a smaller cavity, which is more conducive to the rapid discharge of the medicine from the liquid outlet 4.

[0037] See also Figures 1 to 3The outer wall of the needle tube 1 is provided with a protective cover 5, which is used to fit the auricle so that the device is firmly on the head; a disposable liquid injection head is detachably connected to the liquid outlet 4, which is used to guide the liquid medicine into the patient's ear canal, and the protective cover 5 is detachably connected to the needle tube 1. In this embodiment, a disposable liquid injection head is provided to avoid poor infection.

[0038] In this embodiment, when in use, the protective cover 5 is fitted to the auricle with the palm of the hand, and the sleeve 3 is located inside the ear canal, so that the entire device is fixed on the patient's head to prevent the sleeve 3 from touching the ear canal due to shaking caused by the user holding the device in mid-air.

[0039] In this embodiment, the size of the sleeve 3 needs to meet the size required for use, that is, its diameter needs to be smaller than the patient's ear size. When the sleeve 3 enters the patient's ear, the outer wall of the sleeve 3 will not be squeezed against the inner wall of the patient's ear, which is convenient for user operation. It should be noted that in this embodiment, the dimensions shown in the drawings do not represent the actual dimensions of the product. The drawings are only for illustrating the structure of the device of this application. The user can set the specific dimensions according to actual needs.

[0040] In this embodiment, a visual component is also included; the visual component includes a micro camera and a display; the display is fixed on the protective cover 5, the display is connected to the micro camera, and the micro camera is arranged on one side of the liquid outlet 4 to display the position of the liquid outlet 4 and the end position of the sleeve 3.

[0041] In this embodiment, currently, during the process of applying medicine to the ear, it is generally necessary to use it with the assistance of an endoscope to prevent the instrument from causing damage to the inner wall of the patient's ear; the purpose of setting up a miniature camera is to provide a visual environment to prevent the instrument from causing damage to the patient's ear.

[0042] Furthermore, it also includes a processor, which includes: an acquisition module and a data processing module; the acquisition module is connected to the micro camera and is used to acquire the image of the affected part in the patient's ear, and the data processing module is used to analyze the image of the affected part in the patient's ear and then provide a treatment strategy.

[0043] In this embodiment, the data processing module uses a neural network model to analyze the image of the affected part in the patient's ear. Specifically:

[0044] The visual acquisition component acquires a picture of the patient's ear injury site, and preprocesses the picture using a graphics preprocessing module, wherein the graphics preprocessing module includes: a denoising submodule, a graphics enhancement submodule, and a graphics generation submodule.

[0045] The denoising submodule is used to smooth the wound site image using a Gaussian kernel, and perform median filtering on the smoothed wound site image, replace each pixel value with the median of its neighborhood pixel values, decompose the image through wavelet transform, perform threshold processing in the wavelet domain, and reconstruct the denoised wound site image through inverse wavelet transform.

[0046] The graphic enhancement submodule is used to adjust the contrast of the wound site image in a linear or nonlinear manner, and adjust the grayscale histogram of the wound site image, thereby enhancing the contrast of the wound site image; perform histogram equalization on the wound site image after the grayscale histogram is adjusted, and use the Laplace operator to sharpen the wound site image to enhance the edge of the target area of ​​the wound site image.

[0047] The graphic generation submodule is used to regenerate the image processed by the graphic enhancement submodule to obtain a wound site image showing the wound contour edge.

[0048] The trained image analysis model is used to analyze the wound site image at the wound contour edge to obtain wound parameters corresponding to the wound site image at the wound contour edge.

[0049] Furthermore, the model training method includes: obtaining a training set, wherein the training set includes an input data set and an output data set; the input data set is an image set of photos of the patient's wound site; the output data set is a wound treatment plan data set of the patient's wound site, and the wound parameter data set includes the shape, size and degree of wound corresponding to each of the patient's wound site photos;

[0050] Build a neural network-based image analysis model;

[0051] Inputting the input data set and the output data set into the image analysis model for training in a one-to-one correspondence, and determining the weight of the data sorting model;

[0052] The data sorting model is trained using multiple training sets, and the final weights are adjusted and obtained with the output data set as the result to obtain the data sorting model.

[0053] In this embodiment, the trauma treatment plan data set can be obtained based on the doctor's clinical experience. For example, the doctor uses the pictures of the affected areas in the files of past patients as a training set, and the treatment plan corresponding to each patient as an output data set to achieve the training of the aforementioned model.

[0054] By adopting the above scheme, before using the device of the present application, medical staff can first insert the flusher into the patient's ear according to needs to obtain the image of the affected part. After processing by the data processing module, a preliminary treatment plan can be obtained to provide the doctor with a preliminary diagnosis strategy. Of course, the treatment strategy proposed in the scheme of the present application is only a preliminary treatment plan, and the doctor needs to further determine it.

[0059] In this embodiment, since the circular ring 8 and the fixed plate 9 cooperate with each other through the T-shaped ring groove 10 and multiple T-shaped slide bars 11, and the sleeve 3 is fixedly connected to the circular ring 8, in the process of the liquid pushing column 2 pushing the medicine into the needle tube 1, the fixed plate 9 will move with the liquid pushing column 2 and push the circular ring 8 and the sleeve 3 to extend into the ear canal through the multiple T-shaped slide bars 11, so that the medicine in the needle tube 1 gradually impacts the deep ear canal through the liquid outlet 4.

[0060] See also Figure 4 The rotary propulsion assembly further includes a ball 12 rollingly embedded in the ring 8 . A spiral groove 13 is formed on the outer wall of the needle tube 1 , and the ball 12 is also rollingly embedded in the spiral groove 13 .

[0061] In this embodiment, since the needle tube 1 is fixed and the ball 12 rolling and engaging inside the ring 8 is also engaged in the spiral groove 13 provided on the outer wall of the sleeve 3, when the ring 8 drives the sleeve 3 to move into the ear canal, the ball 12 will cooperate with the spiral groove 13, so that the ring 8 drives the sleeve 3 to rotate and move into the ear canal, thereby realizing the rotational flushing of the inner wall of the ear canal by the liquid through the liquid outlet 4.

[0062] See also Figures 5 to 7 The sealing assembly includes a liquid retaining tube 14 fixedly disposed inside the sleeve 3, and the liquid retaining tube 14 is slidably sleeved on the end of the needle tube 1;

[0064] In this embodiment, since the liquid retaining cylinder 14 is fixedly arranged inside the sleeve 3 and the liquid retaining cylinder 14 and the needle tube 1 are slidably matched, when the sleeve 3 rotates and moves toward the inside of the ear canal, the liquid retaining cylinder 14 will follow the sleeve 3 to perform synchronous actions, so that the needle tube 1 and the sleeve 3 always maintain a small cavity, which is more conducive to the rapid discharge of the liquid medicine from the liquid outlet 4;

[0065] The sealing ring 16 disposed in the groove 15 is used to ensure the sealing between the liquid retaining cylinder 14 and the needle tube 1 to prevent the drug liquid from entering the gap between the liquid retaining cylinder 14 and the needle tube 1 .

[0066] See also Figures 1 to 3 The needle tube 1, the sleeve 3 and the protective cover 5 are all made of transparent plastic material, and the needle tube 1 is also provided with scale lines.
