Description

Technical Field

[0001] This utility model belongs to the field of medical and nursing technology, and in particular relates to a support brace to prevent foot drop in critically ill patients. Background Technology

[0002] In critically ill patients, prolonged bed rest and compression, especially along the sciatic nerve pathway in the buttocks, can damage the sciatic nerve. The sciatic nerve is a vital nerve in the lower limbs, controlling the movement of the muscles in the calf and foot. Damage to it can cause dysfunction in the muscles it innervates, such as the tibialis anterior, leading to foot drop.

[0003] Chinese patent announcement number CN221654714U discloses a foot support device for critically ill patients with foot drop, including a shell and a breathable protective pad. The breathable protective pad is detachably installed inside the shell, and multiple straps are provided on the outer wall of the shell. Support straps are detachably installed between the shells. The foot support device for critically ill patients with foot drop also includes a comfort component, which is detachably installed inside the bottom end of the shell. The comfort component is used to increase the comfort of wearing the shell and can be replaced according to the usage environment. The comfort component includes a groove plate, a comfort pad, a first locking block, a foot pad, and a fixing block, which can provide a more comfortable wearing experience and can be replaced according to indoor and outdoor environments. The design of the support block and the support plate can support the shell, facilitate placement and arrangement, increase user comfort, and prevent displacement. The connection of the second locking block can fix the support plate and ensure the stability of the support plate when it is not unfolded.

[0004] However, this device has the following drawbacks: while it can limit ankle joint movement, it needs to be loosened after a period of fixation, and then re-fixed, requiring frequent adjustments by medical staff. This makes it inconvenient for medical personnel to use. To address these drawbacks, we propose a support brace to prevent foot drop in critically ill patients. Utility Model Content

[0005] The purpose of this invention is to provide a support brace to prevent foot drop in critically ill patients, thereby solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A support brace to prevent foot drop in critically ill patients, comprising:

[0007] The lower limb protective gear includes a leg support pad, a foot support pad fixedly installed at the left end of the leg support pad, and a leg restraint strap and a foot restraint strap fixedly installed on the surfaces of the leg support pad and the foot support pad, respectively.

[0008] A foot restraint structure, the foot restraint structure including a first sliding frame and a second sliding frame respectively slidably mounted on the surfaces of a leg restraint strap and a foot restraint strap, and a traction component disposed between the first sliding frame and the second sliding frame;

[0009] The traction assembly includes an electric telescopic rod rotatably mounted on the surface of a first sliding frame, a traction rope fixedly mounted on the surface of a second sliding frame, and an adjustment component disposed between the electric telescopic rod and the traction rope.

[0015] The support brace for preventing foot drop in critically ill patients according to this utility model has the following advantages:

[0016] 1. This is a support brace to prevent foot drop in critically ill patients. It consists of a lower limb brace and a foot restraint structure. A leg support pad is worn on the patient's calf, and a foot support pad is worn on the sole of the foot. Driving an electric telescopic rod to retract causes a traction rope to pull the foot support pad, thus fixing the patient's ankle joint. A timer switch allows setting the opening and closing time of the electric telescopic rod. After the set time, the electric telescopic rod resets, allowing the traction rope to loosen and relax the ankle joint and muscles. The timer switch provides cyclical interval traction on the patient's ankle joint, eliminating the need for frequent manual adjustments by medical staff and simplifying its use.

[0017] 2. This support brace for preventing foot drop in critically ill patients, by setting an adjustment component, allows the patient to rotate their foot and overcome the elasticity of the compression spring when prolonged traction on the ankle joint causes discomfort. This allows the guide rod to slide within the guide hole and change the length of the traction component, thereby enabling moderate movement of the patient's ankle joint and avoiding muscle soreness caused by prolonged traction on the ankle joint.

[0029] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a support brace for preventing foot drop in critically ill patients.

[0030] like Figure 1-4 As shown, this utility model provides a support brace to prevent foot drop in critically ill patients, comprising: a lower limb brace and a foot restraint structure.

[0031] The lower limb brace includes a leg support pad 10, a foot support pad 11 fixedly installed on the left end of the leg support pad 10, and a leg restraint strap 12 and a foot restraint strap 13 respectively fixedly installed on the surfaces of the leg support pad 10 and the foot support pad 11.

[0032] The leg support pad 10 is worn on the patient's calf, and the foot support pad 11 is worn on the sole of the foot. Then, the foot support pad 11 is fixed to the patient's foot using the foot restraint strap 13, and the leg support pad 10 is fixed to the patient's calf using the leg restraint strap 12, thereby fixing the device in place.

[0033] The foot restraint structure includes a first sliding frame 20 and a second sliding frame 21 that are slidably mounted on the surfaces of the leg restraint strap 12 and the foot restraint strap 13, respectively, and a traction component disposed between the first sliding frame 20 and the second sliding frame 21. The surfaces of the first sliding frame 20 and the second sliding frame 21 are threaded with locking bolts 40. After tightening the locking bolts 40, the leg restraint strap 12 and the foot restraint strap 13 can be clamped in the first sliding frame 20 and the second sliding frame 21 respectively by means of the locking bolts 40, thereby fixing the first sliding frame 20 and the second sliding frame 21.

[0034] The traction assembly includes an electric telescopic rod 30 rotatably mounted on the surface of the first sliding frame 20, a traction rope 31 fixedly mounted on the surface of the second sliding frame 21, and an adjustment component disposed between the electric telescopic rod 30 and the traction rope 31. The adjustment component includes a support plate 50 fixedly mounted on the telescopic end of the electric telescopic rod 30, a guide hole opened on the surface of the support plate 50, a guide rod 51 slidably mounted on the inner wall of the guide hole, a connecting plate 52 and a baffle 53 respectively fixedly mounted on both ends of the guide rod 51, and a compression spring 54 sleeved on the surface of the guide rod 51. The end of the traction rope 31 away from the second sliding frame 21 is fixedly connected to the left side of the connecting plate 52.

[0035] When the leg support pad 10 is fixed on the patient's lower leg and the foot support pad 11 is fixed on the foot, the electric telescopic rod 30 can be retracted to drive the traction rope 31 to pull the foot support pad 11, thereby fixing the patient's ankle joint.

[0036] The opening and closing time of the electric telescopic rod 30 can be set using the timer switch 60. When the device pulls the patient's ankle joint for the set time, it can drive the electric telescopic rod 30 to return to its original position, thereby allowing the traction rope 31 to relax and relax the ankle joint and muscles. The timer switch 60 can be used for cyclical interval switching, so that the patient's ankle joint can be pulled cyclically at intervals without the need for frequent manual adjustment by medical staff, which is convenient for medical staff to use.

[0037] One end of the compression spring 54 is fixedly connected to the left side of the baffle 53, and the other end of the compression spring 54 is fixedly connected to the right side of the support plate 50. When the patient feels uncomfortable due to prolonged traction of the ankle joint, the patient can rotate the foot and overcome the elasticity of the compression spring 54, thereby driving the guide rod 51 to slide in the guide hole and changing the length of the traction component. This allows for moderate movement of the patient's ankle joint, avoiding muscle soreness caused by prolonged traction of the ankle joint.

[0038] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
