Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical device technology, specifically referring to a debridement device for diabetic foot. Background Technology
[0002] Many foot complications in diabetic patients originate from sensory neuropathy and mild autonomic and motor neuropathy. Among these, sensory neuropathy combined with excessive mechanical stress is a major initiating factor for foot ulcers and infections. Sharp debridement, using a scalpel or scissors to trim necrotic tissue, is the preferred method for removing scabs and non-viable tissue. This debridement promotes wound healing and removes pathogens present in non-viable tissue. If diabetic foot patients do not receive timely treatment, the gangrene in their feet may continue to develop, potentially leading to more severe foot ulcers. Many patients may therefore have to undergo amputation. Wound debridement for diabetic foot patients must be thorough, completely removing necrotic tissue and exudate from the wound surface. Through proper wound debridement, the symptoms of ulcers can be effectively controlled, preventing further aggravation.
[0003] Current foot debridement devices often require medical staff to manually restrain the patient's legs. Prolonged manual restraint can lead to hand fatigue, reducing the effectiveness of leg restraint. Furthermore, the cleaning chambers of these devices are often exposed to the air. When the patient's foot wound is not being cleaned, external dust can fall into the chamber. When the chamber is in use, this dust mixes with the disinfectant, potentially causing infection on the patient's foot. The water used to rinse the affected area is also contaminated and can easily stick to the inner wall of the device when splashed, making it difficult to clean and posing a risk of cross-infection, thus hindering wound healing. Therefore, a debridement device for diabetic feet has been developed. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides a diabetic foot debridement device. The device utilizes an adaptive adjustment mechanism to control a hydraulic actuator, which drives the base and fixing column to slide, thus adjusting the height of the enclosure and resolving the issue of inability to adapt to patient positioning. A fixing and sealing mechanism reverses the inner ring of the annular elastic cloth, facilitating foot extension. A fixing servo motor and other mechanisms clamp the lower leg, ensuring the inner ring is tightly sealed against the skin, reducing staff fatigue and improving debridement efficiency. In the disinfection mechanism, the user, wearing gloves, observes the debridement process through a transparent sealing cover. Stepping on foot switch one allows the circulation frame to rotate, adjusting the angle of the disinfection nozzle and removing droplets. Stepping on foot switch two adjusts the distance between the nozzle and the wound, and simultaneously activating the disinfection pump, enabling simultaneous debridement and disinfection in a closed environment, preventing external bacterial infection. A self-cleaning mechanism allows disinfectant droplets to fall into a waste container and splash-proof grid. After debridement, a cleaning servo motor and disinfection pump are activated for self-cleaning, preventing future bacterial infection. The waste container can be extracted for waste disposal.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention is provided with an adaptive adjustment mechanism. By controlling the operation of the adjustable hydraulic device, the base can be driven to slide in the telescopic groove, and the fixed column can slide on the outer surface of the base, thereby adjusting the height of the box and realizing the technical effect of adjusting the height of the device. This effectively solves the problem that the existing technology cannot adapt to the patient's position. (2) The present invention is provided with a fixed sealing mechanism, which flips the inner ring of the annular elastic cloth into the open groove, making it convenient for the patient to insert his foot into the box. After the patient's foot is inserted into the box, the user can control the fixed servo motor to rotate through the electrical control panel. Since the threads at both ends of the bidirectional threaded rod are opposite, the two fixed seats will slide on the inner wall of the fixed slide groove through the bidirectional threaded rod, thereby clamping the patient's lower leg. At this time, the buffer pad plays a buffering role, reducing the patient's discomfort. At the same time, the inner ring of the annular elastic cloth is removed from the open groove. Since the inner ring contains an elastic rubber ring, the inner ring can be tightly attached to the patient's skin surface to complete the seal, thereby fixing the patient's foot, reducing the fatigue of medical staff, and improving the efficiency of wound cleaning. (3) The present invention is equipped with a disinfection mechanism. The user wears medical rubber gloves and inserts them into the box through the operation port. To achieve a better sealing and sterile effect, the opening of the rubber gloves can be fixed at the operation port. Through the transparent glass sealing cover, medical staff can clearly observe and clean the patient's wound. When disinfecting, step on foot switch one, and the circulating servo motor drives half gear one and two to rotate in opposite directions at the same speed through the power and transmission gears. Since only half of the circumferential surface of the two gears has teeth, the circulating frame can be rotated back and forth, thereby adjusting the angle of the disinfection nozzle. At the same time, the rubber scraper removes the disinfection droplets on the inner surface of the sealing cover. Step on foot switch two, and the adaptive servo motor drives the disinfection crossbar to slide through the adaptive threaded rod, which can adjust the distance between the disinfection nozzle and the wound. When both foot switches are stepped on at the same time, the disinfection pump works and sprays the disinfection liquid to the wound. This realizes the simultaneous cleaning and disinfection in a closed environment, which solves the problem of easy infection by external pathogens during wound cleaning in the prior art. (4) The present invention is equipped with a self-cleaning mechanism. When disinfecting the patient's wound, the disinfectant droplets will fall into the waste liquid box below and the anti-splash grid seams on the side wall, reducing the problem of infection caused by droplet splashing. After the wound is cleaned, the user can start the cleaning servo motor to rotate through the electrical control panel. Through the cleaning threaded rod, the cleaning rack slides on the side wall of the box, which in turn drives the cleaning nozzle to slide. At the same time, the disinfection pump is controlled by the electrical control panel to pump the disinfectant through the cleaning nozzle to the anti-splash grid, thus completing the self-cleaning of the device and avoiding bacterial infection during the next use. This achieves the technical effect of self-cleaning and effectively solves the problem of virus growth caused by exposure storage in the prior art. In addition, the waste liquid box can be pulled out from the side wall of the box and the waste liquid inside can be sent to the outside for treatment. Attached Figure Description

The splash guard 501 is fixedly arranged in an array on the inner side wall of the housing 1. The cleaning servo motor 503 is fixedly arranged in an array on the inner wall of the housing 1.

The cleaning nozzle 505 is connected to the output end of the disinfection pump 412 through a hose. The waste liquid box 506 is slidably arranged on the inner bottom wall of the housing 1.
[0027] An electrical control panel 101 is fixedly installed on the side wall of the housing 1, and foot switch one 102 and foot switch two 103 are fixedly installed on the side wall of the base 202. The electrical control panel 101 is electrically connected to the regulating hydraulic device 204, the fixed servo motor 312, the circulating servo motor 421, the adaptive servo motor 429, the disinfection pump 412, the cleaning servo motor 503, the foot switch one 102 and the foot switch two 103 via wires.
[0028] The two ends of the bidirectional threaded rod 313 have opposite thread directions. The bidirectional threaded rod 313 is connected to the fixed seat 314 by threads. The power gear 423 meshes with the transmission gear 424. Half gear one 425 and half gear two 426 mesh with the circulation gear 427 respectively. The number of teeth of half gear one 425 and half gear two 426 is half that of the normal gear. The cleaning threaded rod 504 is connected to the cleaning frame 502 by threads.
[0029] The side wall of the fixed seat 314 is arc-shaped, the buffer pad 315 is arc-shaped and made of flexible rubber, the sealing cover 321 is arc-shaped and made of transparent glass, the rotating shaft of the circulation frame 422 coincides with the arc shaft of the sealing cover 321, the rubber scraper 4212 is in contact with the inner wall of the sealing cover 321 and is made of elastic rubber.
[0030] In practical use, the patient can first lie down or sit on the bed, and at the same time, the hydraulic device 204 can be adjusted through the electrical control panel 101. This will cause the base 202 to slide in the telescopic groove 203, and the fixed column 201 to slide on the outer surface of the base 202. This will adjust the height of the box 1, thus achieving the technical effect of adjusting the height of the device and effectively solving the technical problem that the existing technology cannot adapt to the patient's position. The user can then flip the inner ring of the annular elastic cloth 322 into the open slot 324, making it easier for the patient to insert their foot into the box 1. When the patient's foot is inside the box 1, the user can control the fixed servo motor 312 to rotate via the electrical control panel 101. Since the threads at both ends of the bidirectional threaded rod 313 rotate in opposite directions, the two fixed seats 314 can slide on the inner wall of the fixed slide groove 311 through the bidirectional threaded rod 313, thereby clamping the patient's lower leg. The buffer pad 315 acts as a buffer at this time to reduce patient discomfort. At the same time, the inner ring of the annular elastic cloth 322 can be removed from the open slot 324. Since the inner ring of the annular elastic cloth 322 contains an elastic rubber ring, it can seal the inner ring tightly against the patient's skin surface, thereby fixing the patient's foot, reducing the fatigue of medical staff, and improving the efficiency of wound cleaning. The user can then put on medical rubber gloves and insert them into the box 1 through the operating port 323 (for better sealing and sterility, the opening of the rubber gloves can be fixed at the operating port 323). Since the sealing cover 321 on the box 1 is transparent glass, medical staff can clearly observe the patient's wound and perform debridement. When it is necessary to disinfect the patient's wound, the user can step on the foot switch 102, which will control the rotation of the cyclic servo motor 421. Through the power gear 423 and the transmission gear 424, the half gear 1 425 and the half gear 2 426 will be activated. Rotating in opposite directions at the same speed, since half-gear 425 and half-gear 426 only have half the number of teeth on their circumferential surfaces, when half-gear 425 engages with the circulating gear 427, half-gear 426 is not engaged with the circulating gear 427, thus driving the circulation frame 422 to rotate. When half-gear 425 disengages from the circulating gear 427, half-gear 426 engages with the circulating gear 427, causing the circulation frame 422 to rotate, thereby achieving the technical effect of adjusting the angle of the circulation frame 422 and the disinfection nozzle 413. The reciprocating rotation of the circulation rack 422 causes the rubber scraper 4212 to slide back and forth on the inner surface of the sealing cover 321, which can remove disinfectant droplets splashed on the inner surface of the sealing cover 321 and avoid limiting the field of vision of medical staff. When the circulation rack 422 is rotated to face the wound, the foot switch 102 can be stopped to fix the circulation rack 422. When more detailed disinfection of the patient's wound is required at close range, the user can step on the foot switch 2103, which will start the adaptive servo motor 429 to rotate. Through the adaptive threaded rod 4210, the disinfection crossbar 4211 can be adjusted. The inner wall of the groove 428 slides, thereby adjusting the distance between the disinfection nozzle 413 and the wound. Stopping the foot switch 103 fixes the disinfection crossbar 4211. When spray disinfection is required, the user can simultaneously press the foot switch 102 and the foot switch 103 to start the disinfection pump 412. This allows the disinfectant in the disinfection tank 411 to be sprayed onto the patient's wound through the disinfection nozzle 413, achieving the technical effect of disinfecting the wound edge in a closed environment. This effectively solves the technical problem of external bacterial infection during wound cleaning in the existing technology. When disinfecting a patient's wound, disinfectant droplets will fall into the waste liquid box 506 below and into the gaps of the anti-splash grid 501 on the side wall, thereby reducing the technical problem of droplet splashing and infection. After the wound cleaning is completed, the cleaning servo motor 503 can be started by the electrical control panel 101 to rotate. Through the cleaning threaded rod 504, the cleaning frame 502 can be driven to slide on the side wall of the box 1, which in turn can drive the cleaning nozzle 505 to slide. At the same time, the disinfection pump 412 is controlled by the electrical control panel 101 to pump the disinfectant through the cleaning nozzle 505 to the anti-splash grid 501, completing the self-cleaning of the device and avoiding bacterial infection during the next use. It achieves the technical effect of self-cleaning and effectively solves the technical problem of virus growth caused by exposure storage in the prior art. At the same time, the waste liquid box 506 can be pulled out from the side wall of the box 1 to send the waste liquid inside to the outside for treatment. Once the debridement is complete, simply reverse the fixed servo motor 312 and flip the inner ring of the annular elastic cloth 322 into the open slot 324 to easily remove the patient's foot.
