Description

Technical Field

[0001] The invention relates to the technical field of medical care equipment, in particular to a diabetic foot decompression device. Background Art

[0002] The diabetic foot decompression device is a medical auxiliary equipment specially used for foot decompression, care and rehabilitation of diabetic foot patients. It aims to relieve the pressure on the patient's feet, promote wound healing and improve blood circulation in the feet.

[0003] Chinese patent CN110584870A discloses "a care device for diabetic foot wounds", which is equipped with a foot massage component that can massage the patient's foot to facilitate the patient's recovery. It is also equipped with a heating chamber that can heat the patient's foot to facilitate blood circulation in the patient's foot, save energy and protect the environment, and is conducive to promotion and use.

[0004] The exudate from the patient's foot wound often carries pathogenic microorganisms such as bacteria and viruses, and the hot and humid environment provides ideal conditions for the reproduction of these pathogens. The heating chamber in the device heats the foot with water vapor. Although it can increase the local temperature, promote vasodilation and improve blood circulation, the hot air flow it generates will become a carrier for the spread of pathogens. If the water vapor or heated air carries the pathogens in the exudate to the surrounding environment or contacts the patient's wound again, it may cause secondary contamination. This phenomenon can be explained by the principle of aerosol transmission in microbiology. Aerosol transmission is a way to spread pathogens using tiny droplets or particles suspended in the air as carriers. When pathogens attach to these particles and spread with the air flow, their range of transmission can be greatly increased. Studies have shown that if the nursing device does not filter or disinfect the generated hot air flow, the pathogens will spread into the indoor environment with the aerosol, causing cross-contamination and increasing the risk of infection. Therefore, the device does not fully consider hygiene issues, which will aggravate the spread of pathogens, posing a threat to patients and the surrounding environment. Summary of the invention

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a diabetic foot decompression device, which has the following beneficial effects:

[0019] 1. The diabetic foot decompression device utilizes a decompression mechanism and the arrangement of the filter and the placement of the bactericidal drug to help ensure that the water flow output through the device is effectively treated, thereby reducing the risk of contamination when the water flow that may carry pathogens is output through the nozzle, and reducing the potential risk of infection by effectively filtering the water flow.

[0020] 2. The diabetic foot decompression device uses a top water bath mechanism. Through the sealing design of the flexible hollow parts and the heating system, the device minimizes the loss of hot air flow, so it can effectively control the heat to be concentrated in the area that needs to be heated. This closed design reduces the potential pollution and pathogen transmission risks caused by hot air.

[0021] 3. The diabetic foot decompression device uses a decompression mechanism to start the drive motor to drive the impeller, which drives water through the filter, input pipe, hollow cylindrical block, and telescopic tube into the hollow bar, and then outputs through the hollow block and nozzle, using the power of the water flow to generate a certain pressure and massage effect. The sprayed water can stimulate the foot skin, promote blood circulation, relieve fatigue, and bring a comfortable massage experience. In addition, the impact of the water flow can also promote blood return to the foot, enhance the disease resistance and rehabilitation effect of the foot, and further accelerate the wound healing and comfort of diabetic foot patients.

[0022] 4. The diabetic foot decompression device is set up with a decompression mechanism. When the nozzle sprays, it is subjected to a large reaction force to drive the hollow block to rotate. The hollow block drives the nozzle to rotate and spray. The nozzle can continuously adjust the spray angle during rotation to ensure that the water flow evenly and comprehensively impacts the surface of the foot. Through this rotary spray design, it can provide a more three-dimensional and multi-angle massage effect, improve local blood circulation, help to care for the wound surface of diabetic foot patients, improve comfort and treatment effect, and drive the motor to rotate the reciprocating screw through the belt. The reciprocating screw drives the connecting block and the hollow bar to move back and forth, and drives the nozzle to move back and forth to spray. The reciprocating design can prevent the water flow from being overly concentrated in a certain area, avoid the unevenness of the massage effect, effectively promote blood circulation, and further improve the efficacy. Through this reciprocating spray mechanism, the device can provide more detailed and comprehensive care for the foot wound surface of diabetic foot patients.

[0023] 5. The diabetic foot decompression device uses a massage mechanism. The reciprocating movement of the hollow bar drives the reciprocating movement of the raised block. The reciprocating movement of the raised block contacts different guide columns, so that the guide column drives the cube block and the connecting roller to press and massage the sole of the foot upward. This design can provide a rhythmic foot massage effect, help promote blood circulation, relieve foot pressure, and effectively stimulate the muscles and blood vessels of the foot. Through reciprocating pressing and massage, the device can further help diabetic foot patients relieve foot fatigue, reduce foot edema, promote wound healing, and provide a comfortable treatment experience.

[0024] 6. The diabetic foot decompression device is set up with a top water bath mechanism, and the connector is connected to the flexible hollow part. The hot water in the telescopic tube is output through the cylindrical block, the connecting hose, the connector, and the flexible hollow part, so that the flexible hollow part bulges to tightly resist the legs, preventing the hot air in the body from floating out, thereby effectively isolating the hot air flow in the body and preventing the leakage of the hot air flow. At the same time, it provides a warm heating effect for the legs and heats the legs. At the same time, the hot water in the flexible hollow part is discharged downward through the oblique output port to impact the legs with water flow, so that the circulation in the flexible hollow part and the legs are impacted by water flow at the same time. This design not only enhances the heating effect of hot water on the legs, but also promotes blood circulation in the legs through water flow impact, performs hydrotherapy on the legs, and relieves muscle fatigue and tension. Through the dual effects of warmth and water flow, patients can obtain a more comfortable and effective hydrotherapy effect, which helps improve blood flow and reduce leg discomfort.

[0045] The reciprocating movement of the hollow strip 37 drives the reciprocating movement of the protruding block 47, and the reciprocating movement of the protruding block 47 contacts different guide columns 45, so that the guide columns 45 drive the cube block 44 and the connecting roller 46 to press and massage the sole of the foot upward. This design can provide a rhythmic foot massage effect, help promote blood circulation, relieve foot pressure, and effectively stimulate the muscles and blood vessels of the foot. Through reciprocating pressing and massage, the device can further help diabetic foot patients relieve foot fatigue, reduce foot edema, promote wound healing, and provide a comfortable treatment experience.
