Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a debridement device for diabetic foot. Background Technology

[0002] Diabetic foot is a common and serious complication of diabetes, requiring regular debridement to prevent infection and worsening. With the increasing prevalence of diabetes, debridement equipment for diabetic foot is playing an increasingly important role in clinical treatment.

[0003] However, existing diabetic foot debridement equipment has a problem: when both the instep and sole of the patient's foot need debridement, the structure supporting the leg is not easy to adjust, making it impossible for medical staff to effectively debride different parts of the foot from the same operating position. Specifically, the structure of the existing equipment is not easy to adjust the position of the foot, which requires medical staff to adjust their own position to perform debridement operations on the instep and sole of the foot separately. This operation method increases the workload of medical staff. In addition, the existing equipment is not convenient for collecting disinfectant. Summary of the Invention

[0004] The present invention aims to provide a wound cleaning device for diabetic foot, so as to reduce the workload of medical staff and facilitate the collection of disinfectant.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a debridement device for diabetic foot, comprising a support, a reclining chair, and a foot and leg support mechanism. The reclining chair is connected to the support, and two support ears are connected to the reclining chair, with a support rod fixedly connected between the two support ears. The foot and leg support mechanism includes a drive component, a support plate, and at least one stretching and collecting unit. The support plate is rotatably connected to the support rod, and the drive component is rotatably connected to both the support and the support plate. The stretching and collecting unit includes double protrusions, a push rod, and a stretching block. The support plate has a notch, a groove, and a channel connecting the notch and the groove. The double protrusions are fixedly connected to the support rod at the notch. The push rod is slidably disposed within the channel. The stretching block is slidably disposed within the groove and can be reset. One end of the push rod is connected to the stretching block, and the other end of the push rod contacts the double protrusions. The stretching block has a strap, a collecting groove, and a frame plate. The frame plate is slidably connected to the stretching block and can gradually cover the collecting groove.

[0006] The beneficial effects of this solution are as follows: After the patient lies on the recliner, the support plate supports the patient's legs, and the heel is placed on the stretching block. The medical staff then use straps to tie the patient's ankle. After cleaning the instep, the medical staff use the drive mechanism to rotate the support plate, thereby lifting the leg to facilitate cleaning the sole of the foot. During the cleaning process, the frame plate does not block the collection tank. The detached tissue flows directly from the sole of the foot to the heel with the disinfectant, or flows from both sides of the instep to the heel and then into the collection tank for collection.

[0007] During the rotation of the support plate, the tension block returns to its original position, and the frame plate gradually blocks the collection trough, which helps to reduce the problem of waste liquid spillage during the rotation of the support plate. Moreover, when the support plate is about to rotate into place, the double protrusions drive the push rod and tension block to move, thereby applying appropriate tension to the lower leg through the straps. This helps to stimulate the formation of a new microvascular system in the lower limb. The main reason why diabetic foot is difficult to heal is the poor blood supply to the lower limb. By traction, it is beneficial to improve the blood supply to the foot and promote ulcer healing.

[0008] Moreover, the muscles of diabetic patients are often resistant to insulin. Passive stretching helps to activate glucose uptake. When the muscles are stretched, the veins are compressed, and blood is squeezed toward the heart. When the muscles return to their original state, the veins refill and fresh blood is drawn in from the arterial end, thus forming a passive calf muscle pump, promoting venous return in the lower limbs, and also helping to reduce foot congestion and edema.

[0009] In addition, this method stretches the lower leg only when the support plate is about to rotate into position, which can avoid the lower leg bearing the combined stress of torsion and stretching at the same time and causing tissue damage. Moreover, through intermittent stretching, the rotation process becomes a natural relaxation phase, blood flow is restored, and the tissue obtains oxygen and nutrients. Stretching begins again after the rotation is in place, maintaining a regular stretching-relaxation rhythm, which is more conducive to stimulating angiogenesis.

[0010] Furthermore, the stretching collection unit also includes a sealing block, which is located at the chute and connected to the support plate. The frame plate is connected to the sealing block, and a spring is provided between the stretching block and the sealing block.

[0011] Furthermore, the stretching block is provided with an arc-shaped heel groove.

[0012] Furthermore, there are two stretch collection units.

[0013] Furthermore, the recliner has an armrest on one side.

[0014] Furthermore, the recliner also has two straps near the support plate, and each strap is connected to a cover that can cover the knees.

[0015] Furthermore, the push rod is a telescopic rod. Attached Figure Description
