[0002] Diabetic foot is a common complication in diabetic patients. It refers to a series of problems in the lower limbs caused by long-term high blood sugar levels, which can cause blood circulation and nerve damage, including ulcers, infections, necrosis, etc. In severe cases, amputation may be required. The formation of diabetic foot is usually closely related to the following factors: Nerve damage: Long-term high blood sugar levels can damage peripheral nerves, especially those in the lower limbs, leading to sensory loss and numbness. Patients may not feel injuries or pressure on their feet, which can lead to trauma without them realizing it. Poor blood circulation: Diabetes can also cause damage to blood vessels, especially the microvessels in the lower limbs, affecting blood circulation in the feet, reducing the supply of oxygen and nutrients, making wounds difficult to heal and prone to infection.

The whole process is convenient and fast, and is convenient for medical staff to use, thereby increasing the convenience during use; at the same time, a clamping and fixing mechanism is arranged on the outside of the seepage collection tank 5. When the adsorption work is performed, the seepage collection tank 5 can maintain a stable state when collecting waste liquid, avoiding interference from external factors, which may cause the seepage collection tank 5 to tip over. At the same time, under the action of the clamping and fixing mechanism, the disassembly of the seepage collection tank 5 is also facilitated, further increasing the convenience when using the overall device.
[0020] Specifically, the display alarm mechanism includes a control panel 6 fixedly mounted on the front side of the upper end of the outer frame 1, a display screen 601 is embedded in the interior of the control panel 6, and a number of adjustment knobs 61 and control buttons 62 are provided on one side of the display screen 601. A pressure sensor 63 is fixedly mounted on the upper surface of the outer frame 1, and a red alarm light 64 and a green alarm light 65 are also fixedly mounted on the upper surface of the outer frame 1.

The fixed sleeve is connected with a turning handle 78, and the clamping and fixing mechanism also includes a socket 75 fixedly mounted on both ends of the inner side of the outer frame 1, and the movable rod 73 is movably plugged into the inside of the socket 75. The end of the movable rod 73 away from the connecting plate 72 is fixedly connected with a clamping member 76, and the exudate collection tank 5 is arranged between the two clamping members 76, and the two clamping members 76 fixedly clamp the square base 51 at the lower end of the exudate collection tank 5.

At this time, the screw rods 71 screwed and installed at both ends of the rotating member 7 begin to move, which will drive the connecting plate 72 and the movable rod 73 to move, thereby driving the two clamping members 76 away from each other. At this time, during the movement of the clamping member 76, the roller 77 starts to rotate, reducing friction and making the rotation more labor-saving. When the two clamping members 76 move away from each other to the appropriate position, the fixed and clamped seepage collection tank 5 is removed, the waste liquid inside it is processed, and disinfection is performed.
[0024] Specifically, the adsorption component 4 includes a frame body 41 and a dressing 42. The rear side of the frame body 41 is connected to the end of the drainage tube 3.

The dressing 42 is installed on the inner side of the frame body 41, and a limiting mechanism for the dressing 42 is provided around the outer side of the frame body 41. The dressing 42 is a polyurethane silver ion dressing. The frame of the adsorption component 4 is adhesively connected with a layer of sealing paste.

The dressing 42 is a polyurethane silver ion dressing, which has antibacterial and disinfecting effects, thereby avoiding infection of the patient's wound during adsorption. At the same time, a limiting mechanism is provided on the outer side of the dressing 42. Under the action of the limiting mechanism, when the dressing 42 needs to be replaced, the card plate 43 is pulled open. In the process of pulling the card plate 43 open, the spring 46 at the bottom of the card plate 43 is stretched and is in a stretching device. Without applying external force, the card plate 43 will quickly return to its original position, thereby being able to limit and fix the dressing 42 installed inside the frame body 41.
[0026] A method for using a diabetic foot wound negative pressure suction device comprises the following steps: S1: Debugging, adjusting the required adsorption pressure value of the adsorption component 4 according to the needs of the diabetic foot wound patient through the pressure value displayed on the display screen 601 of the control panel 6, so as to use the adsorption component 4 to treat the patient's wound; S2: Adsorption. After debugging is completed, the frame body 41 of the adsorption assembly 4 is used to fit the wound on the patient's foot to be treated and maintain a sealed fit. Then, the negative pressure pump 2 is started, and the adsorbed liquid flows into the exudate collection tank 5 along the drainage tube 3; S3: Cleaning. When the adsorption is completed, the clamping and fixing mechanism is opened to unlock the fixed seepage collection tank 5. Then, the sealing plug 52 provided at the bottom of the seepage collection tank 5 is opened to treat the waste liquid and disinfect the seepage collection tank 5.
