Description

Technical Field

[0001] This invention relates to the field of human head support structure technology, specifically a human head support for testing. Background Technology

[0002] Tongue diagnosis is a method of diagnosis and differentiation that uses the observation of changes in the color and shape of the tongue. It is one of the important observation indicators in the observation of the tongue in traditional Chinese medicine. However, the traditional tongue diagnosis, which relies on human vision to observe changes in the color and shape of the tongue, is easily affected by external factors, and the results of diagnosis and differentiation are easily affected by the subjective factors of the observer, which leads to a lot of controversy and error in the diagnosis and differentiation of tongue diagnosis.

[0003] However, with the development of science and technology, a diagnostic and identification technology that uses machine vision to assist in tongue diagnosis has emerged. It converts the color and shape changes of the tongue into image information and transmits it to a dedicated image processing system to obtain information such as the pixel distribution, brightness, and shape of the tongue color, thereby greatly improving the accuracy of tongue diagnosis.

[0004] However, existing methods for collecting tongue information using machine vision equipment lack a specific head support structure, making it difficult for the patient's head to maintain a specific position and angle with the machine vision equipment. Consequently, when collecting tongue image information, the color and shape of the collected image information are easily deviated and shadows are produced due to the angle of light, which greatly affects the accuracy and efficiency of tongue information collection, and the stability and reliability are poor.

[0005] Therefore, there is an urgent need for a head support structure for acquiring tongue diagnosis image information to solve the problems existing in the current machine vision equipment when acquiring patients' tongue information. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] This invention provides a human head support for detection, which has the advantages of efficient and accurate acquisition of patient tongue information, preventing deviations or shadows in the acquired image information due to the angle of light, and high stability and reliability. It solves the problem that existing machine vision devices, when acquiring patient tongue information, lack a specific head support structure, making it difficult for the patient's head to maintain a specific position and angle with the machine vision device. Consequently, when acquiring tongue image information, deviations in color and shape and shadows are easily caused by the angle of light, which greatly affects the accuracy, efficiency, stability and reliability of tongue information acquisition.

[0008] (II) Technical Solution

[0009] This invention provides the following technical solution: a human head support for detection, comprising a fixed frame, a movable block movably sleeved in the middle of the inner cavity of the fixed frame, and both sides of the movable block forming a transmission connection with the inner cavity of the fixed frame through a set of pressure springs, forming a sealed space between the bottom of the outer side of the movable block and the inner wall of the fixed frame. A set of side airbags is provided on both sides of the inner wall of the movable block, and a support airbag is provided at the bottom of the inner wall of the movable block. A pressure sensor is provided inside the top of the support airbag, and the two sets of side airbags are interconnected with the inner cavities of the support airbags. The interior of the left side airbag is connected to the sealed space on the left side and is connected to an external air pressure pump through a first connecting pipe. The support airbag... The pressure sensor and the air pump form an electrical feedback connection, and the air pump can be automatically started when the pressure sensor is triggered by pressure to squeeze and deliver gas into the side airbag and the support airbag. The interior of the right side airbag is connected to the right side sealed space, and is connected to the exhaust mechanism fixedly installed on the right side of the top of the fixed frame through a second connecting pipe. A solenoid valve is provided in the second connecting pipe and forms an electrical feedback connection with the pressure sensor on the support airbag. At the same time, the solenoid valve is in the normally open state and only closes when the pressure sensor is triggered by pressure. A fixed bracket is fixedly installed in the middle of the top of the fixed frame, and one end of the fixed bracket is provided with a mounting shaft for fixing the machine vision equipment.

[0010] Preferably, the exhaust mechanism includes a mounting base, a connecting sleeve is fixedly sleeved inside the mounting base, the bottom of the inner cavity of the connecting sleeve is connected to one end of the second connecting pipe, and a constant pressure spring is movably sleeved on the top of the inner cavity of the connecting sleeve. A linkage piston is movably sleeved on the bottom of the inner cavity of the connecting sleeve and forms a transmission connection with the constant pressure spring. A first conductive ring is provided on the top of the outer surface of the linkage piston, and a second conductive ring is provided in the middle of the inner cavity of the connecting sleeve. An exhaust hole communicating with the outside is provided in the middle of the right side of the inner cavity of the connecting sleeve. A one-way valve is provided inside the first connecting pipe.

[0012] Preferably, the elastic force of the constant pressure spring is less than the sum of the elastic forces of the side airbag and the support airbag. Therefore, when the solenoid valve returns to the normally open state, the elastic forces of the side airbag and the support airbag can drive the linkage piston to move upward and compress the constant pressure spring.

[0013] Preferably, when the linkage piston moves upward and compresses the constant pressure spring to its minimum length, the first conductive ring and the second conductive ring come into contact with each other, while one end of the exhaust hole is offset from the outer surface of the linkage piston.

[0014] (III) Beneficial Effects

The human head support used for detection uses gas filling to fix the patient's head and maintain the corresponding position and angle with the machine vision equipment on the mounting shaft. This allows for precise image acquisition of the patient's tongue without deviation or shadows caused by lighting angle issues, resulting in high stability and reliability.

[0017] 2. The human head support used for testing can automatically control the triggering state and start-up time of the disinfection components on the fixed bracket by using the gas filled in the side airbags and support airbags for the exhaust mechanism and its upper structure. Thus, after the human head support is used, it can be disinfected in time to prevent the growth and spread of bacteria and viruses, thereby effectively improving the hygiene of the human head support during use.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-2 A human head support for detection includes a fixed frame 1 that can be fixedly mounted on an operating table. A U-shaped movable block 2 is movably sleeved in the middle of the inner cavity of the fixed frame 1. Both sides of the movable block 2 are connected to the inner cavity of the fixed frame 1 via a set of pressure springs 3. A sealed space is formed between the bottom outer side of the movable block 2 and the inner wall of the fixed frame 1, allowing the movable block 2 to move upward and compress the pressure springs 3 when filled with gas. A set of side airbags 4 are provided on both sides of the inner wall of the movable block 2, and a support airbag 5 is provided at the bottom of the inner wall of the movable block 2. The side airbags 4 and support airbags 5 are used to hold the patient's face. A pressure sensor 6 is provided inside the top of the support airbag 5, and the inner cavities of the two sets of side airbags 4 and support airbags 5 are interconnected. Meanwhile, both the side airbags 4 and the support airbags 5 are made of elastic materials that are harmless to the human body. The interior of the left side airbag 4 is connected to the sealed space on the left and is connected to an external air pump through the first connecting pipe 7. The pressure sensor 6 on the support airbag 5 forms an electrical feedback connection with the air pump. When the pressure sensor 6 is triggered by pressure, the air pump can be automatically started to squeeze and deliver gas into the side airbags 4 and the support airbag 5, thereby adjusting the height of the control block 2 and the degree of expansion of the upper side airbags 4 and the control block 2, so as to fix the patient's head in a specific position and maintain a corresponding angle relationship. The interior of the right side airbag 4 is connected to the sealed space on the right and is connected to the exhaust mechanism 10 fixedly installed on the right side of the top of the fixed frame 1 through the second connecting pipe 9. Figure 3 As shown, a solenoid valve 18 is provided in the second connecting pipe 9 and forms an electrical feedback connection with the pressure sensor 6 on the support airbag 5. At the same time, the solenoid valve 18 is in a normally open state and only closes when the pressure sensor 6 is triggered by pressure. After the image information of the tongue is acquired, the solenoid valve 18 can be automatically triggered to discharge the gas filled in the side airbag 4 and the support airbag 5, so that the movable block 2 returns to its initial state. A fixed bracket 11 arranged in an inclined state is fixedly installed in the middle of the top of the fixed frame 1. One end of the fixed bracket 11 is provided with a mounting shaft 12 for fixing and installing the machine vision equipment, and the machine vision equipment is used to acquire the patient's tongue image information.

[0024] At the same time, different devices can be installed on the mounting shaft 12 according to the actual usage to collect different information about the patient's face.

[0025] like Figure 3 As shown, in this technical solution, the exhaust mechanism 10 includes a mounting base 14 fixedly installed on the right side of the front of the fixed frame 1. A connecting sleeve 15 is fixedly sleeved inside the mounting base 14. The top of the connecting sleeve 15 is provided with a vent hole communicating with the outside. The bottom of the inner cavity of the connecting sleeve 15 is connected to one end of the second connecting pipe 9. A constant pressure spring 16 is movably sleeved on the top of the inner cavity of the connecting sleeve 15. A linkage piston 17 is movably sleeved on the bottom of the inner cavity of the connecting sleeve 15 and forms a transmission connection with the constant pressure spring 16. A sealing bushing is provided on the outer surface of the linkage piston 17 to increase the sealing between it and the inner wall of the connecting sleeve 15. A first conductive ring 19 is provided on the top of the outer surface of the linkage piston 17, and a second conductive ring 20 is provided in the middle of the inner cavity of the connecting sleeve 15. An exhaust hole 21 communicating with the outside is provided in the middle of the right side of the inner cavity of the connecting sleeve 15 to exhaust the gas filled in the side airbag 4 and the support airbag 5. Figure 1 As shown, the first connecting pipe 7 is equipped with a one-way valve 8, which allows the gas on it to flow only towards the side airbag 4 and the supporting airbag 5. The other end of the fixed bracket 11 is fixedly installed with a disinfection component 13, which forms a series circuit with the first conductive ring 19 and the second conductive ring 20, thereby controlling the triggering state of the disinfection component 13. The disinfection component 13 can be flexibly selected as an ultraviolet disinfection lamp.

[0026] like Figure 3 As shown, in this technical solution, the first conductive ring 19 on the linkage piston 17 and the second conductive ring 20 on the connecting sleeve 15 are initially misaligned, thereby keeping the disinfection component 13 on the fixed bracket 11 in a normally closed state, so as not to cause harm to the human body when the machine vision device collects image information of the patient's tongue. In addition, one end of the exhaust port 21 is initially overlapped with the linkage piston 17 to cut off the communication between the inner cavity of the connecting sleeve 15 and the outside.

[0027] In this technical solution, the elastic force of the constant pressure spring 16 is less than the sum of the elastic forces of the side airbag 4 and the support airbag 5. Therefore, when the solenoid valve 18 returns to the normally open state, the elastic force of the side airbag 4 and the support airbag 5 can drive the linkage piston 17 to move upward and compress the constant pressure spring 16.

[0028] In this technical solution, when the linkage piston 17 moves upward and compresses the constant pressure spring 16 to its minimum length, the first conductive ring 19 and the second conductive ring 20 come into contact with each other, and one end of the exhaust hole 21 is offset from the outer surface of the linkage piston 17. Then, the first conductive ring 19 and the second conductive ring 20 come into contact and open the disinfection component 13 to disinfect the movable block 2 and its structure. At the same time, the positions of the linkage piston 17 and the exhaust hole 21 are offset to discharge the gas in the side airbag 4 and the support airbag 5.

[0029] Furthermore, the activation time of the disinfection component 13 can be adjusted by adjusting the flow rate of gas through the exhaust port 21, thereby improving its disinfection effect on the moving block 2 and its structure.

[0030] The usage method and working principle of this embodiment are as follows:

[0031] First, the human head support is fixedly installed on the operating table using the fixed frame 1. At the same time, the machine vision equipment is fixedly installed on the mounting shaft 12. Meanwhile, the pipes and circuit systems on it are connected in accordance with the above.

[0032] When a patient needs to use a machine vision device to collect image information of their tongue, when the chin is placed on the support airbag 5, the pressure sensor 6 on it can be squeezed and triggered. Then, under the feedback system of the circuit, the solenoid valve 18, which is normally open, is closed first. At the same time, the external air pressure pump is triggered, and gas is filled into the sealed space on the movable block 2 and the side airbags 4 and support airbags 5 on it through the first connecting pipe 7. While the movable block 2 moves upward, the side airbags 4 and support airbags 5 on both sides expand, thereby fixing the patient's head in a specific position and maintaining the corresponding angle with the machine vision device on the fixed bracket 11, so that it can accurately collect image information of the patient's tongue.

[0033] After the image information acquisition is completed, when the patient's head leaves the support airbag 5, the pressure sensor 6 on it is no longer triggered by the pressure. The external air pump is turned off and the gas is stopped being squeezed and delivered to the side airbag 4 and the support airbag 5. At the same time, the solenoid valve 18 returns to the normally open state. Then, under the action of the elasticity of the side airbag 4 and the support airbag 5, the gas inside is compressed and enters the inner cavity of the connecting sleeve 15 through the second connecting pipe 9. This drives the linkage piston 17 to move upward and compress the constant pressure spring 16 to the minimum length, so that the first conductive ring 19 and the second conductive ring 20 come into contact with each other and trigger the disinfection component 13 to disinfect the moving block 2 and its structure. At the same time, the positions of the linkage piston 17 and the exhaust port 21 are staggered, so that the gas is discharged to the outside of the connecting sleeve 15 through the exhaust port 21.

[0034] After all the gas in the side airbag 4 and the support airbag 5 has been expelled, the linkage piston 17 moves downward under the elastic force of the constant pressure spring 16, forcing the first conductive ring 19 and the second conductive ring 20 to be misaligned and shutting off the sterilization component 13. At the same time, the linkage piston 17 and the exhaust port 21 are aligned and the exhaust port 21 is blocked again, so that the human head support structure returns to its initial state.
