Description

Technical Field

[0001] The present invention relates to the technical field of point-reading teaching, and particularly relates to a point-reading device for medical knowledge education and publicity. Background Art

[0002] With the aging of the population and the change of lifestyle, chronic diseases (such as cardiovascular diseases, diabetes, and cancers) have become the main health threats, and such diseases are often closely related to personal behaviors. It is urgent to improve the prevention awareness through education and publicity. From SARS to COVID-19, new and emerging infectious diseases have emerged frequently, and the public's demand for prevention and control knowledge (such as vaccination and personal protection) has increased sharply. Education and publicity have become the key to blocking the transmission chain. The uneven distribution of medical resources has led to low health literacy among vulnerable groups (such as rural areas and low-income populations), and education and publicity can narrow the health information gap.

[0003] Traditional paper manuals or oral explanations rely on the ability to read text, but some groups (such as the elderly, those with low educational levels, and visually impaired patients) have difficulty understanding complex medical content. Some existing point-reading devices use multi-sensory interaction of "vision + hearing + touch" (such as clicking on a picture to trigger voice / animation), reducing the cognitive threshold and improving the information absorption efficiency.

[0004] In the prior art, a patent with the authorized publication number CN212061489U discloses a point-reading book (including a front cover board, a connecting board, a bottom cover board, a point-reading paper, a support platform, and a point-reading component. The first-page point-reading paper is fixedly arranged on the front cover board, the last-page point-reading paper is fixedly arranged on the support platform fixed on the bottom cover board. The point-reading component includes a touch component, a circuit board, a speaker, a power supply, a charging port, and a start-stop switch. The charging port and the start-stop switch are fixedly arranged on the outer end face of the support platform, the circuit board, the speaker, and the power supply are fixedly arranged inside the support platform. The touch component includes a touch switch electrically connected to the circuit board. Touch switches are arranged between the first-page point-reading paper and the front cover board and between the last-page point-reading paper and the support platform. Learning areas are arranged on the front and back of the inner point-reading paper, the back of the first-page point-reading paper, and the front of the last-page point-reading paper. Touch marks and block-distributed learning contents are arranged in the learning areas. The touch marks are all directly opposite the touch switches. Sound holes directly opposite the speaker are arranged on the inner point-reading paper and the last-page point-reading paper), and corresponding content is broadcast by clicking on the point-reading paper to carry out the education and publicity of the content.

[0005] However, it has some deficiencies when used for medical knowledge education for some groups of people (such as the elderly or those with low educational levels, etc.). Especially for some elderly patients in the department of neurology, since they often seek medical treatment due to neurodegenerative diseases, cerebrovascular diseases, etc., their clinical characteristics, treatment, and nursing need to comprehensively consider age-related physiological changes and comorbidities. The common disease types include Alzheimer's disease, Parkinson's disease, cerebrovascular diseases, and other diseases. When conducting education, it is often more difficult. It is difficult for them to perform normal page-turning operations like some young people. For example, when used for an elderly person in a hospital bed, on the one hand, if their hand movement is difficult (such as muscle weakness or the presence of some medical devices), it is difficult for them to turn the page alone and also difficult to perform page-turning operations by hand. On the other hand, if these elderly people can perform autonomous page-turning and page-pointing operations, during the page-pointing process, the movement of their hands is likely to get some liquids (treatment liquids or other living liquids (such as sweat)) onto the page, which is not convenient for cleaning and subsequent page-pointing operations. At the same time, if these liquids are not processed in time, it may lead to a reduction in the service life of the device. And in actual use, the page-pointing device is generally used in a one-to-many form, that is, multiple people or multiple wards use the same instrument crosswise. Each time it is used, the patient's hand is likely to touch the page-pointing paper, thus transferring some germs on the hand to the page-pointing paper, and it is easy to cause cross-infection of some germs during the repeated use process.

[0006] Therefore, the present invention proposes a page-pointing device for medical knowledge education to solve the above problems. Summary of the Invention

[0007] To solve the above problems, the present invention provides a page-pointing device for medical knowledge education. Through multi-mode selection, it is convenient to conduct medical knowledge education for some groups of people (such as the elderly, those with low educational levels, and some elderly patients in the department of neurology), and at the same time, clean the liquid on the surface of the device during the page-pointing process.

[0008] To achieve the above object, the technical solution of the present invention is as follows: A page-pointing device for medical knowledge education includes a housing and a controller built in the housing. A working slot is opened at the top of the housing. An information component for recording medical knowledge is arranged in the working slot. A rolling component for driving the information component to turn pages is arranged on the inner side wall of the working slot. A stabilizing component for stabilizing the information component is arranged on the inner top wall of the working slot. A cleaning component for cleaning the information component is arranged inside the fixing component; An auxiliary component for page-pointing the content shown by the information component is arranged on the surface of the top of the housing.

[0009] Principle of the basic solution: The information component is scrolled and turned pages by the rolling component. At the same time, through the restriction of the stabilizing component, the information component is further stabilized and provides support for the auxiliary component during page-pointing. When the information component moves, the cleaning component is used to clean it automatically, thereby cleaning sundries such as liquids on its surface.

[0010] The above - mentioned solution has the following beneficial effects: Compared with the prior art, the present invention has an automatic cleaning function. The design of the cleaning component effectively solves the problem that the surface of the information component is easily contaminated with dust, liquid and other sundries, ensuring the clarity and hygiene of the reading interface. This not only extends the service life of the device but also improves the user experience. In the process of medical knowledge education, a clean reading environment will undoubtedly enhance the learners' concentration and comprehension ability.

[0011] Furthermore, the rolling component includes two rolling shafts symmetrically and rotatably connected to the inner side wall of the working groove. One end of each rolling shaft is coaxially and fixedly connected with a first gear, and each first gear meshes with a second gear; there are two motors corresponding to the two rolling shafts one by one inside the housing, and the output shafts of the motors are respectively coaxially and fixedly connected with the corresponding second gears; the motors are all electrically connected to the controller.

[0012] Beneficial effects: The combination of double - motor independent drive and gear transmission structure realizes the precise two - way control of the information component. Specifically, two symmetrically arranged rolling shafts are driven by the meshing of the first gear and the second gear, and cooperate with independently controlled motors to rotate synchronously or asynchronously under the coordination of the controller. This not only ensures the flatness of the information component during the page - turning process but also can adjust the page - turning speed and direction according to needs. This design is particularly suitable for the display of medical materials with different thicknesses and materials. When encountering adhered pages, the system can automatically increase the torque to achieve flexible separation, avoiding the page - jamming problem easily caused by traditional single - shaft drive.

[0013] Furthermore, the information component includes a point - reading paper, and both ends of the point - reading paper in the width direction are respectively fixedly connected to the two rolling shafts.

[0014] Beneficial effects: By directly fixing both ends of the point - reading paper to the rolling shafts, a closed - loop transmission structure is formed, making the page always in a uniformly tensioned state. This design not only eliminates the common paper offset or wrinkle phenomena in traditional page - turning devices but also can achieve millimeter - level precision synchronous displacement during the rolling process, which is particularly suitable for displaying medical imaging materials that require high - definition presentation. When the cleaning component operates, the tensioned paper surface can effectively enhance the uniformity of the scraping - type cleaning force, ensuring the thorough removal of liquid residues.

[0015] Furthermore, the stabilizing component includes a fixing plate fixedly connected to the inner top wall of the working groove. A groove is opened at the top of the fixing plate, and a fixing through - groove is opened on one side of the fixing plate in the width direction. The bottom wall of the groove is located below the bottom wall of the fixing through - groove.

[0016] Beneficial effects: Through the stepped - structure design of the fixing plate and the groove, a three - point positioning system is formed. When the point - reading paper is unfolded, its top edge automatically fits into the groove, and the bottom is limited by the fixing through - groove, realizing longitudinal displacement constraint. This structure makes the paper surface present a certain pre - tensioning force, effectively eliminating the vibration offset caused by high - frequency point touch.

[0017] Further, the auxiliary component includes a placement groove opened at the top end of the housing. A plurality of magnetic suction seats are provided on the bottom wall of the placement groove. A point reading pen is placed in the placement groove, and a plurality of magnetic suction layers corresponding to the magnetic suction seats are provided on the surface of the point reading pen.

[0018] Beneficial effects: The magnetic coupling design realizes the intelligent positioning and anti-loss protection of the point reading pen.

[0019] Further, the cleaning component includes sponge layers provided on the bottom wall and the top wall of the fixed through groove; the point reading paper passes through the fixed through groove and contacts the sponge layers.

[0020] Beneficial effects: The double-sided clamping type sponge layers constitute a dynamic cleaning system, realizing two-way wiping each time the point reading paper is displaced. The high-density hydrophilic sponge (porosity 92%) can instantaneously absorb more than 90% of the liquid residues on the surface of the point reading paper, and its siphon effect cooperates with the movement of the rolling shaft to form a continuous self-cleaning cycle.

[0021] Further, annular grooves are provided on the surface of the rolling shaft along its axial direction, and both ends in the width direction of the point reading paper are respectively fixed in the annular grooves of the two rolling shafts.

[0022] Beneficial effects: The limiting structure of the annular groove realizes the zero-offset fixation of the point reading paper.

[0023] Further, the width of the fixed through groove is greater than the width of the groove.

[0024] Beneficial effects: The differential groove width design forms a progressive guiding structure. The gradient difference between the groove and the fixed through groove generates a self-correction effect, which can automatically compensate for the paper cutting error and reduce the installation difficulty. At the same time, the widened through groove reserves a dynamic adjustment space for the cleaning component (sponge layer), preventing the cleaning sponge from hardening and failing due to long-term extrusion.

[0025] Further, a tracking module electrically connected to the controller is fixedly connected to the top end of the housing; the tracking module is used to judge whether the user uses the point reading pen, and based on the judgment result, execute the manual point reading mode or the automatic point reading mode.

[0026] Further, when the user uses the point reading pen and is in the manual point reading mode, if all the information recorded on the current point reading paper has been read, automatic page turning is performed; when the user does not use the point reading pen, in the automatic point reading mode, page turning is performed according to the position where the user's eyes focus.

[0027] Beneficial effects: In manual reading mode, if all the information on the current reading paper has been read, the tracking module will send a signal to the controller to trigger the automatic page turning function, so as to seamlessly transition to the next page of content without the user having to turn the page manually, thus improving the fluency of reading. In automatic reading mode, the device uses advanced eye tracking technology to intelligently determine when to turn the page based on the position where the user's eyes are focused, thus achieving a more personalized reading experience. This intelligent page turning mechanism not only improves reading efficiency, but also further enhances the interactivity and fun of medical knowledge education.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0038] The following is a further detailed description through specific embodiments:

[0039] Embodiment 1:

[0040] As shown in the attached Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 : A point-reading device for medical knowledge education and publicity, including a housing 1 and a controller built in the housing 1. A working groove is opened at the top of the housing 1. An information component for recording medical knowledge is arranged in the working groove. A rolling component for driving the information component to turn pages is arranged on the inner side wall of the working groove. A stabilizing component for stabilizing the information component is arranged on the inner top wall of the working groove. A cleaning component for cleaning the information component is arranged inside the fixing component; an auxiliary component for point-reading the content shown by the information component is arranged on the top surface of the housing 1.

[0041] The rolling component includes two rolling shafts 7 symmetrically and rotatably connected to the inner side wall of the working groove. One end of each rolling shaft 7 is coaxially and fixedly connected with a first gear 9. The first gears 9 are all engaged with a second gear 10; two motors corresponding to the two rolling shafts 7 one by one are arranged inside the housing 1. The output shafts of the motors are respectively coaxially and fixedly connected with the corresponding second gears 10; the motors are all electrically connected to the controller. The two motors can rotate synchronously or asynchronously under the coordination of the controller, which not only ensures the flatness of the information component during the page-turning process, but also can adjust the page-turning speed and direction (previous page or next page) according to needs. And the periphery of the first gear 9 and the second gear 10 can be wrapped with sound-absorbing materials, which can effectively reduce the running noise while ensuring the transmission accuracy and avoid interfering with the education and publicity process.

[0042] The information component includes a point-reading paper 4 on the surface of which medical graphic and text information is printed. Both ends of the point-reading paper 4 in the width direction are respectively clamped to two rolling shafts 7. Annular grooves are arranged on the surfaces of the rolling shafts 7 along their axial directions, and both ends of the point-reading paper 4 in the width direction are respectively fixed in the annular grooves of the two rolling shafts 7. For example, the depth of the annular groove can be set to 0.8 mm, and the groove wall is provided with an anti-slip silica gel layer, and the quick disassembly and assembly of the point-reading paper 4 are realized through a buckle structure. In addition, for the update or replacement of medical graphic and text information, the method of pasting a pre-prepared sticker (recording medical education information) on the point-reading paper 4 and performing point-reading through an auxiliary component can also be adopted, so as to avoid frequent replacement of the point-reading paper 4. At the same time, a grid is printed on each page of the point-reading paper 4 to facilitate the positioning and pasting of the sticker. If replacement is needed, only the sticker needs to be replaced.

[0043] The auxiliary component includes a placement groove 2 opened at the top end of the housing 1. A plurality of magnetic suction seats are arranged on the inner bottom wall of the placement groove 2. A point-reading pen 3 is placed in the placement groove 2. A plurality of magnetic suction layers corresponding to the magnetic suction seats are arranged on the surface of the point-reading pen 3. The point-reading pen 3 is coupled with the magnetic suction seats through the magnetic suction layers on its surface. At the same time, a Hall sensor is included in the magnetic suction seat for detecting the taking and placing state of the point-reading pen 3.

[0044] The stabilizing component includes a fixing plate 6 integrally formed on the inner top wall of the working groove. A groove is opened at the top end of the fixing plate 6. A fixing through groove 11 is opened on one side of the fixing plate 6 in the width direction. The bottom wall of the groove is located below the bottom wall of the fixing through groove 11, and the width of the fixing through groove 11 is greater than the width of the groove, so that the edge parts of the point-reading paper 4 in the length direction are all located in the fixing through groove 11, thereby further ensuring the smoothness of the movement process of the point-reading paper 4 and also reducing the possibility of large-range deviation of the point-reading paper 4 during point-reading with the point-reading pen 3, resulting in jamming.

[0045] The cleaning component includes sponge layers 12 adhered to the bottom wall and the top wall of the fixing through groove 11. The porosity of the sponge layers 12 is preferably a sponge with a porosity of ≥90%. At the same time, the size design of the sponge layers 12 needs to ensure that when the point-reading paper 4 passes through the fixing through groove 11, it contacts and presses against the sponge layers 12. At the same time, diversion channels are arranged inside the sponge layers 12, and a plurality of collection bins 8 communicated with the diversion channels are clamped at the bottom of the fixing plate 6, so as to guide the absorbed liquid to the collection bins 8.

[0046] For people who are prone to spill liquids such as domestic water / liquid medicine on the dot paper 4, the specific process of this solution is as follows: When the user turns the page (automatically / manually), the motor drives the rolling shaft 7 to rotate. During the page-turning process, the dot paper 4 passes through the fixed through groove 11 at a constant speed of 0.2 - 1.5 m / min. At this time, the double-sided sponge layer 12 (porosity 92%, Shore hardness 25 HA) on the top and bottom walls of the fixed through groove 11 clamps the surface of the dot paper 4 with a contact pressure of 0.3 - 0.8 N, forming a two-way wiping effect. The hydrophilic modification treatment of the sponge layer 12 enables it to instantaneously absorb more than 90% of the liquid (such as splashed disinfectant), and a single page-turning can remove water droplets with a diameter ≤ 3 mm. Then, a diversion channel is arranged inside the sponge layer 12. The diversion channel is preferably designed in a serpentine structure to increase the contact area. The absorbed liquid is guided to the collection bins 8 (capacity 5 mL) on both sides through capillary action. At the same time, in order to prevent liquid backflow, desiccants such as diatomite desiccants are filled in the collection bins 8, which can convert the liquid into a gel state to prevent backflow, and the collection bins 8 can be cleaned regularly.

[0047] In addition, when this device is actually used, it is generally not the case that there is one device for each bed. It may be that one device is shared by one ward or multiple wards, that is, one device needs to conduct medical knowledge education for multiple patients. Then, in addition to the above cleaning of the dot paper 6, it also needs to be disinfected regularly, that is, in line with medical care principles. Then, several disinfection bins corresponding to the sponge layer one by one are clamped at the bottom end of the fixing plate. The disinfection bins are all connected to disinfection pipelines, and the disinfection pipelines respectively extend to the sponge layer corresponding to the disinfection tank, and disinfection pumps are arranged in the disinfection pipelines. A disinfection button electrically connected to the disinfection pump is arranged on one side of the housing 1.

[0048] For example: A total of 3 such dot reading devices are configured in the neurology ward of a certain tertiary hospital for the education of patients with Alzheimer's disease and Parkinson's disease. Each device is used about 20 times a day, and the following disinfection process needs to be carried out:

[0049] Disinfectant selection: Use 0.5% hydrogen peroxide solution (compatible with sponge material, no residue), inject it into the sponge layer through the disinfection pipeline to avoid corroding electronic components.

[0050] Regular disinfection: Once in the morning and once in the evening every day, the head nurse presses the disinfection button for 3 seconds. The disinfection pump injects the disinfectant into the sponge layer at a flow rate of 5 mL / min. At the same time, the motor rotates to make the dot paper 4 roll and rub against the sponge layer for disinfection, killing pathogens such as Escherichia coli and Staphylococcus aureus. After the disinfection is completed, press the disinfection button again to stop the disinfection. The excess liquid during disinfection flows into the collection bin 8, and the inside of the collection bin 8 can also be disinfected.

[0051] Example 2:

[0052] The difference from Embodiment 1 is that a tracking module 5 electrically connected to the controller is fixedly connected to the top end of the outer shell 1; the tracking module 5 is used to determine whether the user uses the point-reading pen 3, and based on the judgment result, execute the manual point-reading mode or the automatic point-reading mode. Among them, the tracking module 5 may preferably include a millimeter-wave radar array, an infrared camera, and a pressure sensor array sensor to achieve the operation and switching of dual modes.

[0053] Specifically, when the user uses the point-reading pen 3 and performs the manual point-reading mode, when the millimeter-wave radar detects that the distance between the point-reading pen 313 and the paper surface is <10 mm and lasts for >0.5 s, and at the same time the pressure sensor detects a touch pressure of ≥3 N, the controller starts the point-reading trajectory analysis and calculates the proportion of the area of the read area in real time. When the single-page point-reading completion rate ≥98%, the motor 7 rotates synchronously at an angular acceleration of 0.8 rad / s 2 to complete the page turning (time-consuming 1.2 s).

[0054] When the user does not use the point-reading pen 3, that is, the point-reading pen 3 is not taken out (the magnetic suction seat maintains the adsorption state), and the infrared camera recognizes that the user's eye focus point persists, the automatic point-reading mode is performed. The pupil center coordinates are calculated in real time through the sub-pixel tracking algorithm (accuracy ±0.1 mm) and mapped to the corresponding position of the point-reading paper 4. If the gaze duration in the same area >15 s, the controller drives the motor 7 to turn the page at a slow movement speed of 0.2 rad / s 2 to avoid interruption of thinking; when it is detected that the user's line of sight moves away >5 s, the page turning is automatically paused and the low-power standby state is entered. Thus, it is convenient for users with inconvenient limb (arm) movement in the hospital bed to perform automatic point-reading, that is, phonetic reading based on the position where their eyes are looking, to help them understand medical knowledge.

[0055] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
