Description

Technical Field

[0001] This utility model relates to the field of medical protective equipment technology, specifically to a heel flap protection device. Background Technology

[0002] After heel flap transplantation, the affected limb needs to be properly elevated to facilitate arterial blood supply and venous return, and to ensure the heel is suspended and avoids pressure. Simply supporting the lower leg with a support to elevate the limb, while preventing pressure on the heel, results in prolonged pressure on the posterior side of the lower leg, affecting arterial blood supply and venous return at the heel, which is detrimental to flap survival. Suspending the lower leg with a suspension device is also not conducive to flap survival. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a heel flap protection device. This heel flap protection device is simple to operate, can be reused, effectively relieves pressure by suspending the heel, and improves the survival rate of the flap.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A heel flap protection device, characterized in that it comprises: Bowl-shaped rubber pads are used to wrap the patient's heel; Foot covers are used to secure cup-shaped rubber pads to the patient's heel; The bowl-shaped rubber pad is made of low-temperature thermoplastic board; The foot cover includes a first foot-shaped fabric and a second foot-shaped fabric that fit the patient's ankle and foot. The first and second foot-shaped fabrics are symmetrical to each other, and the ankle segments of the first and second foot-shaped fabrics are integrated. A first detachable connection structure is provided between the outer edges of the ankle segments of the first and second foot-shaped fabrics, a second detachable connection structure is provided between the upper edges of the foot segments of the first and second foot-shaped fabrics, and a third detachable connection structure is provided between the lower edges of the foot segments of the first and second foot-shaped fabrics. A semi-circular notch is provided at the rear of the foot segments of both the first and second foot-shaped fabrics. When the first, second, and third detachable connection structures are connected, the two semi-circular notches form an annular opening that can accommodate the patient's heel. The size of the annular opening is smaller than the size of the bowl-shaped rubber pad, and the center of the bowl-shaped rubber pad protrudes from the annular opening.

[0005] The aforementioned bowl-shaped rubber pad is simply placed on the patient's heel and supported by the ring opening of the foot cover, making it easy for the patient to remove and replace the dressing.

[0006] The aforementioned low-temperature thermoplastic sheet is a novel medical material made from a specially synthesized high-molecular polyester through a series of physical and chemical processes. It is used in the manufacture of orthopedic external fixation devices, orthotics, and braces. Due to its outstanding properties such as non-absorption of radiation, excellent shaping effect after softening by heating, and unique shape memory function (allowing for reheating and reshaping when the shaping is unsatisfactory), as well as its simple operation and convenient fixation, it is an ideal external fixation material for orthopedic treatment.

[0007] When using, first immerse the bowl-shaped rubber pad in 60-70℃ hot water until it becomes completely transparent and softened. Stretch it appropriately according to the patient's heel size and shape it on-site before use (if the shaping is unsatisfactory, the bowl-shaped rubber pad can be re-immersed in 60-70℃ hot water to soften it again; the material can then be restored to its original size and shape and reshaped for reuse). Next, place the shaped bowl-shaped rubber pad on the patient's heel, and then put the foot cover on the patient's foot. The ankle segments of the first and second foot-shaped fabrics are connected by a first detachable connection structure, and the foot segments of the first and second foot-shaped fabrics are connected by a second and third detachable connection structure. Two semi-circular notches form an annular opening that can accommodate the patient's heel. The edge of the bowl-shaped rubber pad abuts against the edge of the annular opening, providing stable support and protection for the patient's heel.

[0008] In the preferred embodiment, the first detachable connection structure, the second detachable connection structure, and the third detachable connection structure are all Velcro or straps.

[0009] In a further preferred embodiment, the Velcro includes a hook face and a fleece face that mates with the hook face.

The corresponding second connecting straps are respectively located on the outer side of the ankle segment, the upper side of the foot segment, and the lower side of the foot segment of the second foot-shaped fabric.

[0011] In a preferred embodiment, both the first and second foot-shaped fabrics are made of two layers of fabric sewn together, with a sponge interlayer between the two layers. This sponge interlayer possesses high elasticity and extensibility. The addition of this sponge interlayer inside the first and second foot-shaped fabrics provides excellent cushioning for the foot during patient activity, reducing pressure and improving comfort.

[0012] In a further preferred embodiment, the fabric is made of spandex or polyester fiber. Spandex fiber has excellent elasticity, allowing the foot cover to better conform to the foot contours of different patients and ensuring comfortable wear. Polyester fiber, on the other hand, has high strength, abrasion resistance, and wrinkle resistance, ensuring the durability of the foot cover and extending its service life.

[0013] In a preferred embodiment, a reinforcing fabric piece is sewn onto the edge of the semi-circular notch, wrapping around the upper and lower surfaces of the edge of the semi-circular notch. The reinforcing fabric piece increases the strength of the semi-circular notch, and when the bowl-shaped rubber pad is placed in the annular opening, the annular opening with the full circle of reinforcing fabric provides better fixation for the bowl-shaped rubber pad.

[0014] Compared with the prior art, this utility model has the following advantages: 1. This utility model uses a combination of a bowl-shaped rubber pad and a foot cover to elevate the patient's heel, effectively suspending the heel to reduce pressure, reducing pressure on the heel flap, promoting arterial blood supply and venous return, and improving the survival rate of the flap.

[0015] 2. The detachable connection structure and the removable design of the cup-shaped rubber pad of this utility model foot cover allow for flexible adjustment of the tightness of the rubber cover, ensuring a comfortable fit between the rubber cover and the patient's foot. This facilitates disassembly and replacement when changing dressings, is simple to operate, and saves time and energy for medical staff and patients.

[0016] 3. The properties of the low-temperature thermoplastic plate allow the bowl-shaped pad to be shaped on-site according to the size of the patient's heel, and it can be repeatedly shaped and used, improving the applicability of the device. Attached Figure Description
