Description

Technical Field

[0001] The present invention relates to the technical field of image acquisition for oral cleaning, and in particular to an intelligent oral cleaning and image acquisition device and system after esophageal cancer surgery. Background Art

[0002] The most common complications after esophageal cancer surgery are oral ulcers or other oral diseases. The main reason is that the oral mucosa is damaged during esophageal cancer surgery. At this time, if the oral cavity does not have good hygiene conditions, it will lead to bacterial proliferation and oral ulcers.

[0003] Therefore, in order to reduce the incidence of oral ulcers in patients after esophageal cancer surgery, medical staff generally advise patients to maintain oral hygiene. Common ways to maintain oral hygiene include brushing teeth, gargling, etc. However, the common method only relies on the patient's own oral sensation to judge the oral hygiene. Some smaller food residues accumulate in the dead corners of the mouth, which cannot be cleaned by traditional oral cleaning, so the patient's oral hygiene cannot be fully guaranteed. Of course, there are also devices on the market specifically for cleaning the dead corners of the oral cavity, which mainly include a handheld handle, and the output end of the handheld handle outputs a high-pressure water flow to clean foreign objects in the dead corners of the oral cavity, but the oral cleaning devices on the market lack image acquisition function and cannot meet the needs of patients to operate by themselves. Summary of the invention

[0004] The present invention provides an intelligent oral cleaning image acquisition device after esophageal cancer surgery. The device can capture internal images of the oral cavity by installing a camera on a handheld handle. An air duct is provided with an air pump to avoid generation of aerosol on the camera and blurring of the captured image.

[0005] The technical problem solved by the present invention is achieved by adopting the following technical solutions: On the one hand, the present invention provides an intelligent oral cleaning image acquisition device after esophageal cancer surgery, including a camera, which is placed in a slot at the end of a handheld handle; it also includes: an air duct, which is inside the handheld handle and whose top output end passes through the side wall of the slot and is connected to the inside of the slot, and the bottom input end of the air duct is connected to the output end of an air pump; a controller, the input end of the controller is connected to the output end of the camera, and is used to receive the image captured by the camera, and the output end of the controller is used to send a control signal, and the control signal is used to control the operation of the air pump.

[0006] Preferably, a heating wire for heating the air is provided inside the air duct.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0021] In order to enable those skilled in the art to understand the inventive point of the present invention, the prior art part of the present invention is first described. Figure 1 and Figure 2 The oral cleaning device includes a handheld handle 1 and a tank body 17 that can hold a cleaning liquid (water, saline or other fluids that can be used for oral cleaning). A water pump 19 is provided at the inner bottom of the tank body 17, and a liquid storage space 18 is provided above the water pump 19. The input end of the water pump 19 can extract the cleaning liquid, and the output end of the water pump 19 is connected to a water pipe 20. The output end of the water pipe 20 is connected to the waterway 10 inside the handheld handle 1. A water spray pipe 2 (with a nozzle at the output end, not shown in the figure) is provided at the end of the handheld handle 1 and at the output end of the waterway 10. In order to facilitate the water spray pipe 2 to better align with the area to be cleaned and to facilitate the water spray pipe 2 to move inside the oral cavity, the diameter of the water spray pipe 2 is smaller than the diameter of the handheld handle 1. When cleaning the dead corners of the oral cavity, Aim the output end of the water spray pipe 2 at the position that needs to be cleaned, start the water pump 19, and the cleaning liquid flows out along the water pump 19, the water pipe 20, the waterway 10, and the water spray pipe 2 to impact the cleaning position to achieve the cleaning effect. The above is the general composition structure and use principle of the existing oral cleaning device, and the details are not elaborated in detail. The above-mentioned existing oral cleaning device can fully clean foreign objects in the dead corners of the oral cavity due to the directional spraying of high-pressure water, maintain oral hygiene, and reduce the incidence of oral ulcers or other oral diseases in patients after esophageal cancer surgery. However, the existing oral cleaning device lacks image acquisition function, so other people are required to clean the patient's mouth, which is very inconvenient. Based on the above situation, the present invention makes the following improvements.

[0022] refer to Figure 3-Figure 8On the one hand, the present invention provides an intelligent oral cleaning image acquisition after esophageal cancer surgery. The main improvement is that, on the basis of the above-mentioned existing oral cleaning device, a camera 5 is installed on the handheld handle 1 to realize the acquisition of the image inside the oral cavity. Specifically, in order to prevent the camera 5 from being blocked by the moisture in the exhaled gas of the human body, resulting in blurred images, the camera 5 is set in the notch 4 at the end of the handheld handle 1, and an air duct 6 is opened inside the handheld handle 1. The output end of the air duct 6 runs through the side wall of the notch 4 to ensure that the wind blown out from the air duct 6 can dry the surface of the camera 5. An air pump 11 is set at the bottom input end position of the air duct 6, and the output end of the air pump 11 is connected to the input end of the air duct 6 to realize air supply to the air duct 6. In order to further ensure that the air entering the oral cavity is The air is clean. By setting a dust cover 12 at the input end of the air pump 11, the hygiene of the oral cleaning process can be further guaranteed, and large particles of dust carried in the air can be prevented from entering the oral cavity. When the camera 5 is used to collect image information inside the oral cavity, the surface of the camera 5 is dried by starting the air pump 11 to control the flow of gas, so as to ensure that the image collected by the camera 5 remains clear. At the same time, when cleaning the blind spots of the oral cavity, the air flow can also flow at the position of the camera 5 to reduce the adhesion of the cleaning liquid on the camera 5 and blow away the cleaning liquid splashed on the camera 5. In order to solve the problem that the camera 5 cannot have sufficient light to obtain images inside the oral cavity in some blind spots or when the opening angle of the oral cavity is limited, lamp beads 8 are also arranged on the side of the camera 5 to realize lighting by emitting light.

[0023] Further, such as Figure 4 As shown, a heating wire is further provided inside the air duct 6, and the heating wire can heat the air inside the air duct 6, so as to realize heating up the surface of the camera 5, and further avoid the phenomenon that the surface temperature of the camera 5 is lower than the internal temperature of the oral cavity, causing the surface of the camera 5 to contact the gas exhaled from the oral cavity, causing the water in the gas to be atomized. At the same time, the hotter air can also prompt the surface of the camera 5 to quickly recover to a dry state.

[0024] Furthermore, by Figure 1 and Figure 3 It can be seen that in order to better align the output end of the water spray pipe 2 with the blind spot in the oral cavity, the water spray pipe 2 is arranged to be in a bent state. In order to ensure that the area photographed by the camera 5 can be directly cleaned, the shooting direction of the camera 5 should be directed to the output end of the water spray pipe 2. Specifically, a conical ridge 3 with a notch 4 on the side wall is provided at the end of the hand-held handle 1. The water spray pipe 2 extends upward from the central position of the conical ridge 3 and bends to one side at the same time. The camera 5 is placed in the notch 4 to achieve a tilt angle, thereby ensuring that the shooting direction of the camera 5 is toward the output end of the water spray pipe 2.

[0025] Furthermore, the operation of the air pump 11 and the water pump 19 are controlled by the controller 9. The water pump 19 and the air pump 11 are controlled by the controller 9 to perform a single operation or a simultaneous operation. In order to facilitate the user to convey instructions to the controller 9 through operation, specifically, a pressure sensor 16 is provided on the handheld handle 1 and is connected to the input end of the controller 9. The controller 9 controls the water pump 19 and the air pump 11 to perform a single operation or a simultaneous operation according to the value of the pressure sensor 16 received. Considering that the air pump 11 is usually not working properly when obtaining the internal image information of the oral cavity, Only when the interruption time is short can it be ensured that the lens position of the camera 5 does not generate water mist at all times. Only when foreign objects are found in the blind spot area, it is necessary to control the water pump 19 to work and clean the blind spot area of ​​the oral cavity. Therefore, the control logic of the controller 9 is preferably set to when the pressure sensor 16 received by the controller 9 has a value, the air pump 11 is controlled to work. When the pressure sensor 16 received by the controller 9 has a value and the value exceeds the set threshold, the controller 9 controls the water pump 19 to work. At this time, the air drying work and oral cleaning work of the camera 5 surface are carried out simultaneously.

[0026] Specifically, a shell 13 with a cavity 14 inside is provided on the hand-held handle 1, and a button 15 is provided on the shell 13. One side of the button 15 is left outside the shell 13 for the user to press, and the other side of the button 15 extends into the cavity 14 for squeezing the pressure sensor 16. When the user squeezes the part of the button 15 left outside the shell 13, the part of the button 15 left inside the shell 13 squeezes the pressure sensor 16. Of course, an elastic element 22 is provided between the part of the button 15 outside the shell 13 and the shell 13 to facilitate the resetting of the button 15.

[0027] Furthermore, the extension shape of the air duct 6 inside the handheld handle 1 can be straight, spiral or serpentine. The straight shape can reduce the manufacturing difficulty of the handheld handle 1 and facilitate processing, while the spiral and serpentine shapes can increase the air path inside the air duct 6, thereby increasing the heating time of the heating wire on the air, and having a better surface drying effect on the camera 5.

[0028] Furthermore, the side of the slot 4 opposite to the outlet end of the air duct 6 is a flat opening 7, thereby preventing the cleaning liquid from accumulating inside the slot 4 and achieving rapid air drying inside the slot 4.

[0029] On the other hand, the present invention also provides an intelligent oral cleaning image acquisition system after esophageal cancer surgery, which includes the above-mentioned intelligent oral cleaning image acquisition device after esophageal cancer surgery and an external terminal 21, which is connected to the image acquisition device by wired or wireless means, and is used to display the image acquired by the image acquisition device in real time. For example, a mobile phone or a computer is used as the external terminal 21, which is connected to the above-mentioned intelligent oral cleaning image acquisition device after esophageal cancer surgery via a data cable or WIFI, so that the user can observe the picture taken by the camera 5 inside the oral cavity in real time, so that the patient can clean the blind spot area of ​​the oral cavity by himself without the assistance of others.

[0030] When in use, firstly, the above-mentioned intelligent oral cleaning image acquisition device after esophageal cancer surgery is powered on. At this time, the camera 5, the heating wire and the lamp bead 8 are all in working state. Then, the intelligent oral cleaning image acquisition device after esophageal cancer surgery is connected to a matching external terminal 21. At this time, the image captured by the camera 5 can be displayed in real time through the outside. The patient holds the handgrip 1 and places the end of the handgrip 1 with the water spray pipe 2 inside the oral cavity. The image captured by the camera 5 at this time is the internal image of the oral cavity and can be displayed through the external terminal 21. By rotating or moving the handgrip 1 to change the shooting position of the camera 5, the interior of the oral cavity can be found. Are there any blind spots, such as between teeth or under the tongue coating, and are there any foreign objects (such as food residues)? Since the camera 5 is inside the oral cavity, it will be affected by the liquefaction of water in the exhaled gas, causing water mist to form on the surface of the camera 5. At this time, a small amount of pressure is applied to the button 15 on the handle to make the air pump 11 work. The air pump 11 blows the external air through the air duct 6 to the surface of the camera 5 to dry the camera 5. When a blind spot with foreign objects is found, the squeezing force on the button 15 is increased, the water pump 19 works, and the high-pressure cleaning fluid sprayed from the water spray pipe 2 cleans the target area. The above is an introduction to the use process of the present invention.

[0031] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
