Description

Technical Field

[0001] The present invention relates to the technical field of foot pressure detection, and specifically to a plantar pressure detection device for diabetic patients. Background Technique

[0002] Diabetic foot refers to the abnormal nerves in the distal lower extremities and varying degrees of vascular lesions in patients after suffering from diabetes. Patients will show symptoms such as ulcers, foot infections, and deep tissue damage. It is difficult for diabetic patients to achieve early monitoring of diabetic foot in their daily lives, resulting in treatment measures being taken only when the condition develops to the late stage, missing the best treatment window period. Diabetic patients need to use a pressure detection device to detect the plantar pressure. Currently, when detecting plantar pressure, it is necessary to detect through a thin film pressure sensor. The patient needs to step on the thin film pressure sensor with the foot, and then detect the pressure generated by different positions of the sole on the thin film pressure sensor. When detecting, not only dynamic detection but also static detection is required. Moreover, the plantar pressure distribution and changes of the tester can be observed through a display screen.

[0003] However, when the existing plantar pressure detection device for diabetic patients is in use, in order to meet the hygiene requirements, the surface of the thin film pressure sensor needs to be manually cleaned by medical staff before or after each use, which is not convenient and hygienic. In addition, after the thin film pressure sensor is used, it cannot be protected in time, making the thin film pressure sensor easily damaged, affecting its detection results and service life. Moreover, the display screen is not only easily contaminated by impurities such as dust and water stains, but also easily scratched by bumps, affecting its display effect and service life.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: For this plantar pressure detection device for diabetic patients, by setting the first reset mechanism, etc., when detection is required, the patient steps on the first inclined surface at the top of the sealing plate. At this time, the two sealing plates can be pushed to move away from each other, and at the same time, the first spring is compressed, so as to ensure that the foot can be placed in the box body and step on the thin-film pressure sensor for detection. At this time, the two sealing plates can move closer to each other under the action of the first spring and contact the calf. After the detection is completed, when the patient lifts the foot, it will abut against the first inclined surface at the bottom of the sealing plate, thereby pushing the two sealing plates to move away from each other, and at the same time, the first spring is compressed. After the foot is separated from the sealing plate, the two sealing plates can move closer to each other under the action of the first spring and abut against each other. And, under the action of the sealing strip, the top of the box body can be sealed and protected, and at the same time, impurities such as dust and water stains can be prevented from entering, avoiding damage to the thin-film pressure sensor, and ensuring the detection effect and service life of the thin-film pressure sensor.

[0016] This plantar pressure detection device for diabetic patients can protect the thin-film pressure sensor when the patient steps on the non-woven fabric during detection by setting up a scraping mechanism, etc., avoiding impurities from falling on the thin-film pressure sensor, ensuring the detection effect and service life. Moreover, after each detection, the handwheel can be rotated, and the rotation of the handwheel drives the rotation of the winding roller, so that the used non-woven fabric can be wound around the side wall of the winding roller. At the same time, when the non-woven fabric moves, under the action of the second inclined plane, the impurities that are likely to fall off the surface of the non-woven fabric can be scraped and cleaned and collected into the collection box. The brand-new non-woven fabric wound around the winding roller can be laid above the thin-film pressure sensor again, eliminating the need for medical staff to clean it manually, making it more convenient and hygienic to use.

[0017] This plantar pressure detection device for diabetic patients can wind up the used non-woven fabric when the winding roller rotates by setting up a limiting mechanism and a tensioning mechanism, etc. At the same time, it can pull the winding roller to rotate and lay the brand-new non-woven fabric above the thin-film pressure sensor again. When the winding roller rotates, it can drive the second fixed ring to rotate. At this time, the sector block slides out of the limiting groove and slides on the side wall of the second fixed ring. At the same time, the third spring is compressed. When the winding roller stops rotating, the sector block can be inserted into the limiting groove again under the action of the third spring for limiting, preventing the winding roller from rotating randomly, making it more stable and reliable. Moreover, under the action of the counterweight, the tensioning roller can be driven to move downward and press against the non-woven fabric through the moving rod and the L-shaped plate, so that after the brand-new non-woven fabric is laid above the thin-film pressure sensor, the non-woven fabric can be tensioned to ensure its use effect.

[0018] This plantar pressure detection device for diabetic patients can sleeve the brand-new rolled non-woven fabric around the side wall of the winding roller after all the non-woven fabric is used up. When it is necessary to remove the used non-woven fabric wound around the winding roller, the second T-shaped guide rod can be pushed, causing the connecting plate and the circular ring to move towards the second cover plate, and at the same time, the second spring is compressed, making it easier to remove the used non-woven fabric, making it more convenient and fast to use. When the second T-shaped guide rod is released, the connecting plate and the circular ring can move back to their original positions under the action of the second spring.

[0019] For this plantar pressure detection device for diabetic patients, by setting up a protection mechanism, etc., when performing detection and when it is necessary to observe through the display screen 23, the moving cover 2403 is pushed to move in the direction close to the fixed plate 2401. At the same time, the fourth spring 2404 and the telescopic cover 2405 are compressed. And when the moving cover 2403 moves, it can drive the moving plate 2411 to move, and drive the sponge block 2409 and the brush bristles 2410 to move, so as to be able to clean the surface of the display screen 23. And under the action of the fifth spring 2408, the sponge block 2409 and the brush bristles 2410 can be made to abut against the surface of the display screen 23, making the cleaning effect better and ensuring the observation effect. After the observation is completed, when the moving cover 2403 is released, the moving cover 2403 can move and reset in the direction away from the fixed plate 2401 under the action of the fourth spring 2404. At this time, the surface of the display screen 23 can be cleaned again through the sponge block 2409 and the brush bristles 2410. And after the telescopic cover 2405 is reset, it can cover the display screen 23, playing a role of sealing and protection, which can not only avoid the pollution of impurities such as dust and water stains, but also avoid bumping and scratching, ensuring its display effect and service life, and further ensuring the detection effect.

After the detection is completed, the top of the box body 1 can be sealed and protected, and at the same time, impurities such as dust and water stains can be prevented from entering, avoiding damage to the thin film pressure sensor 18, ensuring the detection effect and service life of the thin film pressure sensor 18, ensuring the detection effect and service life. After the detection is completed, the used non-woven fabric 20 can be wound up, and at the same time, a new non-woven fabric 20 can be laid above the thin film pressure sensor 18 again and tensioned, eliminating the need for medical staff to manually clean, making it more convenient and hygienic to use.

A second inclined surface 203 is arranged at the bottom of the collection box 202, and a handle 204 is fixedly connected to the side wall of the collection box 202. When the non-woven fabric 20 moves, under the action of the second inclined surface 203, impurities that are likely to fall off the surface of the non-woven fabric 20 can be scraped and cleaned and collected into the collection box 202.

[0025] The tensioning mechanism 3 includes an L-shaped plate 301 disposed in the collection box 15, and the L-shaped plate 301 is connected to the top of the collection box 15 through a constant pressure mechanism 4. A tensioning roller 303 is rotatably connected to the side wall of the L-shaped plate 301 through a rotating shaft 302.

Moreover, when the moving cover 2403 moves, it can drive the moving plate 2411 to move, and drive the sponge block 2409 and the bristles 2410 to move, so as to clean the surface of the display screen 23. And, under the action of the fifth spring 2408, the sponge block 2409 and the bristles 2410 can be abutted against the surface of the display screen 23, making the cleaning effect better and ensuring the observation effect. After the observation is completed, when the moving cover 2403 is released, the moving cover 2403 can move and reset in the direction away from the fixing plate 2401 under the action of the fourth spring 2404.

And after the telescopic cover 2405 resets, it can cover the display screen 23, playing a role of sealing and protection. It can not only avoid the pollution of impurities such as dust and water stains, but also avoid bumping and scratching, ensuring its display effect and service life, and thus ensuring the detection effect.

[0034] Working principle: When in use and detection is required, the patient steps on the first inclined surface 1101 at the top of the sealing plate 11. At this time, the two sealing plates 11 can be pushed to move away from each other. Meanwhile, the first spring 903 is compressed, ensuring that the foot can be placed inside the box body 1 and step on the thin film pressure sensor 18 for detection. At this time, the two sealing plates 11 can move closer to each other under the action of the first spring 903 and contact the calf. After the detection is completed, when the patient lifts the foot, it will abut against the first inclined surface 1101 at the bottom of the sealing plate 11, thus pushing the two sealing plates 11 to move away from each other. Meanwhile, the first spring 903 is compressed. After the foot is separated from the sealing plate 11, the two sealing plates 11 can move closer to each other under the action of the first spring 903 and abut against each other. Moreover, under the action of the sealing strip 12, the top of the box body 1 can be sealed and protected, while preventing impurities such as dust and water stains from entering, avoiding damage to the thin film pressure sensor 18, and ensuring the detection effect and service life of the thin film pressure sensor 18; When detecting, the patient's foot steps on the non-woven fabric 20, which can protect the thin film pressure sensor 18, prevent impurities from falling on the thin film pressure sensor 18, ensure the detection effect and service life. Moreover, after each detection is completed, the handwheel 10 can be rotated. The rotation of the handwheel 10 drives the rotation of the winding roller 21, so that the used non-woven fabric 20 can be wound around the side wall of the winding roller 21. Meanwhile, when the non-woven fabric 20 moves, under the action of the second inclined surface 203, the impurities that are likely to fall off the surface of the non-woven fabric 20 can be scraped and cleaned and enter the collection box 202 for collection. The brand-new non-woven fabric 20 wound around the winding roller 19 can be laid above the thin film pressure sensor 18 again, eliminating the need for manual cleaning by medical staff and being more convenient and hygienic to use; When the winding roller 21 rotates, it can wind up the used non-woven fabric 20. Meanwhile, it can pull the winding roller 19 to rotate, laying the brand-new non-woven fabric 20 above the thin film pressure sensor 18 again. When the winding roller 19 rotates, it can drive the second fixing ring 701 to rotate. At this time, the sector block 703 slides out of the limiting groove 702 and slides on the side wall of the second fixing ring 701. Meanwhile, the third spring 803 is compressed. When the winding roller 19 stops rotating, the sector block 703 can be inserted into the limiting groove 702 again under the action of the third spring 803 for limiting, preventing the winding roller 19 from rotating randomly, being more stable and reliable.
